The 21 | following considerations are for informational purposes only, are not 22 | exhaustive, and do not form part of our licenses. 23 | 24 | Considerations for licensors: Our public licenses are 25 | intended for use by those authorized to give the public 26 | permission to use material in ways otherwise restricted by 27 | copyright and certain other rights. Our licenses are 28 | irrevocable. Licensors should read and understand the terms 29 | and conditions of the license they choose before applying it. 30 | Licensors should also secure all rights necessary before 31 | applying our licenses so that the public can reuse the 32 | material as expected. Licensors should clearly mark any 33 | material not subject to the license. This includes other CC- 34 | licensed material, or material used under an exception or 35 | limitation to copyright. More considerations for licensors: 36 | wiki.creativecommons.org/Considerations_for_licensors 37 | 38 | Considerations for the public: By using one of our public 39 | licenses, a licensor grants the public permission to use the 40 | licensed material under specified terms and conditions. If 41 | the licensor's permission is not necessary for any reason--for 42 | example, because of any applicable exception or limitation to 43 | copyright--then that use is not regulated by the license. Our 44 | licenses grant only permissions under copyright and certain 45 | other rights that a licensor has authority to grant. Use of 46 | the licensed material may still be restricted for other 47 | reasons, including because others have copyright or other 48 | rights in the material. A licensor may make special requests, 49 | such as asking that all changes be marked or described. 50 | Although not required by our licenses, you are encouraged to 51 | respect those requests where reasonable.

Subject to the terms and conditions of this Public License, 148 | the Licensor hereby grants You a worldwide, royalty-free, 149 | non-sublicensable, non-exclusive, irrevocable license to 150 | exercise the Licensed Rights in the Licensed Material to: 151 | 152 | a. reproduce and Share the Licensed Material, in whole or 153 | in part; and 154 | 155 | b. produce, reproduce, and Share Adapted Material. 156 | 157 | 2. Exceptions and Limitations.

Term. The term of this Public License is specified in Section 163 | 6(a). 164 | 165 | 4. Media and formats; technical modifications allowed. The 166 | Licensor authorizes You to exercise the Licensed Rights in 167 | all media and formats whether now known or hereafter created, 168 | and to make technical modifications necessary to do so. The 169 | Licensor waives and/or agrees not to assert any right or 170 | authority to forbid You from making technical modifications 171 | necessary to exercise the Licensed Rights, including 172 | technical modifications necessary to circumvent Effective 173 | Technological Measures. For purposes of this Public License, 174 | simply making modifications authorized by this Section 2(a) 175 | (4) never produces Adapted Material. 176 | 177 | 5. Downstream recipients. 178 | 179 | a. Offer from the Licensor -- Licensed Material. Every 180 | recipient of the Licensed Material automatically 181 | receives an offer from the Licensor to exercise the 182 | Licensed Rights under the terms and conditions of this 183 | Public License. 184 | 185 | b. Additional offer from the Licensor -- Adapted Material. 186 | Every recipient of Adapted Material from You 187 | automatically receives an offer from the Licensor to 188 | exercise the Licensed Rights in the Adapted Material 189 | under the conditions of the Adapter's License You apply. 190 | 191 | c. No downstream restrictions. You may not offer or impose 192 | any additional or different terms or conditions on, or 193 | apply any Effective Technological Measures to, the 194 | Licensed Material if doing so restricts exercise of the 195 | Licensed Rights by any recipient of the Licensed 196 | Material. 197 | 198 | 6. No endorsement. Nothing in this Public License constitutes or 199 | may be construed as permission to assert or imply that You 200 | are, or that Your use of the Licensed Material is, connected 201 | with, or sponsored, endorsed, or granted official status by, 202 | the Licensor or others designated to receive attribution as 203 | provided in Section 3(a)(1)(A)(i). 204 | 205 | b. Other rights. 206 | 207 | 1. Moral rights, such as the right of integrity, are not 208 | licensed under this Public License, nor are publicity, 209 | privacy, and/or other similar personality rights; however, to 210 | the extent possible, the Licensor waives and/or agrees not to 211 | assert any such rights held by the Licensor to the limited 212 | extent necessary to allow You to exercise the Licensed 213 | Rights, but not otherwise. 214 | 215 | 2. Patent and trademark rights are not licensed under this 216 | Public License. 217 | 218 | 3. To the extent possible, the Licensor waives any right to 219 | collect royalties from You for the exercise of the Licensed 220 | Rights, whether directly or through a collecting society 221 | under any voluntary or waivable statutory or compulsory 222 | licensing scheme. In all other cases the Licensor expressly 223 | reserves any right to collect such royalties. 224 | 225 | 226 | Section 3 -- License Conditions. 227 | 228 | Your exercise of the Licensed Rights is expressly made subject to the 229 | following conditions. 230 | 231 | a. Attribution. 232 | 233 | 1. If You Share the Licensed Material (including in modified 234 | form), You must: 235 | 236 | a. retain the following if it is supplied by the Licensor 237 | with the Licensed Material: 238 | 239 | i. identification of the creator(s) of the Licensed 240 | Material and any others designated to receive 241 | attribution, in any reasonable manner requested by 242 | the Licensor (including by pseudonym if 243 | designated); 244 | 245 | ii. a copyright notice; 246 | 247 | iii. a notice that refers to this Public License; 248 | 249 | iv. a notice that refers to the disclaimer of 250 | warranties; 251 | 252 | v. a URI or hyperlink to the Licensed Material to the 253 | extent reasonably practicable; 254 | 255 | b. indicate if You modified the Licensed Material and 256 | retain an indication of any previous modifications; and 257 | 258 | c. indicate the Licensed Material is licensed under this 259 | Public License, and include the text of, or the URI or 260 | hyperlink to, this Public License. 261 | 262 | 2. You may satisfy the conditions in Section 3(a)(1) in any 263 | reasonable manner based on the medium, means, and context in 264 | which You Share the Licensed Material. For example, it may be 265 | reasonable to satisfy the conditions by providing a URI or 266 | hyperlink to a resource that includes the required 267 | information. 268 | 269 | 3. If requested by the Licensor, You must remove any of the 270 | information required by Section 3(a)(1)(A) to the extent 271 | reasonably practicable. 272 | 273 | b. ShareAlike. 274 | 275 | In addition to the conditions in Section 3(a), if You Share 276 | Adapted Material You produce, the following conditions also apply. 277 | 278 | 1. The Adapter's License You apply must be a Creative Commons 279 | license with the same License Elements, this version or 280 | later, or a BY-SA Compatible License. 281 | 282 | 2. You must include the text of, or the URI or hyperlink to, the 283 | Adapter's License You apply. You may satisfy this condition 284 | in any reasonable manner based on the medium, means, and 285 | context in which You Share Adapted Material. 286 | 287 | 3. You may not offer or impose any additional or different terms 288 | or conditions on, or apply any Effective Technological 289 | Measures to, Adapted Material that restrict exercise of the 290 | rights granted under the Adapter's License You apply. 291 | 292 | 293 | Section 4 -- Sui Generis Database Rights. 294 | 295 | Where the Licensed Rights include Sui Generis Database Rights that 296 | apply to Your use of the Licensed Material: 297 | 298 | a. for the avoidance of doubt, Section 2(a)(1) grants You the right 299 | to extract, reuse, reproduce, and Share all or a substantial 300 | portion of the contents of the database; 301 | 302 | b. if You include all or a substantial portion of the database 303 | contents in a database in which You have Sui Generis Database 304 | Rights, then the database in which You have Sui Generis Database 305 | Rights (but not its individual contents) is Adapted Material, 306 | 307 | including for purposes of Section 3(b); and 308 | c. You must comply with the conditions in Section 3(a) if You Share 309 | all or a substantial portion of the contents of the database. 310 | 311 | For the avoidance of doubt, this Section 4 supplements and does not 312 | replace Your obligations under this Public License where the Licensed 313 | Rights include other Copyright and Similar Rights. 314 | 315 | 316 | Section 5 -- Disclaimer of Warranties and Limitation of Liability. 317 | 318 | a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE 319 | EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS 320 | AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF 321 | ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, 322 | IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, 323 | WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR 324 | PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, 325 | ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT 326 | KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT 327 | ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU. 328 | 329 | b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE 330 | TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, 331 | NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, 332 | INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, 333 | COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR 334 | USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN 335 | ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR 336 | DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR 337 | IN PART, THIS LIMITATION MAY NOT APPLY TO YOU. 338 | 339 | c. The disclaimer of warranties and limitation of liability provided 340 | above shall be interpreted in a manner that, to the extent 341 | possible, most closely approximates an absolute disclaimer and 342 | waiver of all liability. 343 | 344 | 345 | Section 6 -- Term and Termination. 346 | 347 | a. This Public License applies for the term of the Copyright and 348 | Similar Rights licensed here. However, if You fail to comply with 349 | this Public License, then Your rights under this Public License 350 | terminate automatically. 351 | 352 | b. Where Your right to use the Licensed Material has terminated under 353 | Section 6(a), it reinstates: 354 | 355 | 1. automatically as of the date the violation is cured, provided 356 | it is cured within 30 days of Your discovery of the 357 | violation; or 358 | 359 | 2. upon express reinstatement by the Licensor. 360 | 361 | For the avoidance of doubt, this Section 6(b) does not affect any 362 | right the Licensor may have to seek remedies for Your violations 363 | of this Public License. 364 | 365 | c. For the avoidance of doubt, the Licensor may also offer the 366 | Licensed Material under separate terms or conditions or stop 367 | distributing the Licensed Material at any time; however, doing so 368 | will not terminate this Public License. 369 | 370 | d. Sections 1, 5, 6, 7, and 8 survive termination of this Public 371 | License. 372 | 373 | 374 | Section 7 -- Other Terms and Conditions. 375 | 376 | a. The Licensor shall not be bound by any additional or different 377 | terms or conditions communicated by You unless expressly agreed. 378 | 379 | b. Any arrangements, understandings, or agreements regarding the 380 | Licensed Material not stated herein are separate from and 381 | independent of the terms and conditions of this Public License. 382 | 383 | 384 | Section 8 -- Interpretation. 385 | 386 | a. For the avoidance of doubt, this Public License does not, and 387 | shall not be interpreted to, reduce, limit, restrict, or impose 388 | conditions on any use of the Licensed Material that could lawfully 389 | be made without permission under this Public License. 390 | 391 | b. To the extent possible, if any provision of this Public License is 392 | deemed unenforceable, it shall be automatically reformed to the 393 | minimum extent necessary to make it enforceable. If the provision 394 | cannot be reformed, it shall be severed from this Public License 395 | without affecting the enforceability of the remaining terms and 396 | conditions. 397 | 398 | c. No term or condition of this Public License will be waived and no 399 | failure to comply consented to unless expressly agreed to by the 400 | Licensor. 401 | 402 | d. Nothing in this Public License constitutes or may be interpreted 403 | as a limitation upon, or waiver of, any privileges and immunities 404 | that apply to the Licensor or You, including from the legal 405 | processes of any jurisdiction or authority. 406 | 407 | 408 | ======================================================================= 409 | 410 | Creative Commons is not a party to its public 411 | licenses.

[Why another toolboard?](#1-why-another-toolboard) 14 | 2. [Why did you make this?](#2-why-did-you-make-this) 15 | 3. [Safety remarks](#3-safety-remarks) 16 | 4. [Open Source Hardware](#4-open-source-hardware) 17 | 18 | --- 19 | 20 | # 1. Why another toolboard? 21 | 22 | There's a multitude of existing toolboards for 3D printers: 23 | 24 | * [Huvud 3D Tool Head](https://hackaday.io/project/174429-huvud-a-3d-printer-tool-head-controller-board) 25 | * [Voron Afterburner Tool-Head](https://www.onetwo3d.co.uk/product/voron-afterburner-tool-head-pcb/) 26 | * [Duet Toolboard](https://www.duet3d.com/Duet3Toolboard1LC) 27 | * [Carabiner PCB](https://github.com/Annex-Engineering/Annex_Engineering_PCBs/blob/master/carabiner-toolboard/buildguide/README.md) 28 | * [Pi G-Code Hat](https://oshwlab.com/matt_1626/pi-g-code-hat) 29 | 30 | They are all great projects, but they are either much more complex, require many difficult to source components, or are simply unavailable / out of stock. 31 | 32 | I wanted something designed specifically for the [EVA platform](https://main.eva-3d.page/) and which makes use of ubiquitous RJ45 cables. 33 | 34 | # 2. Why did you make this? 35 | 36 | Rather than wiring all devices directly from the 3D printer electronics panel to the hotend assembly, this module allows you to connect two simple RJ45 wires between them, and then wire the devices directly using the JST-XH / JST-VH connectors. One module mounts to the hotend, the other mounts on the electronics panel. 37 | 38 | It then makes it simple to swap out a hotend without rewiring everything. It significantly cleans up the wiring and reduces maintenance and upgrading headache. 39 | 40 | **Note:** This module was originally designed to lay flat with 40x40mm dimensions, but a similar project by _"Minty Trebor"_ on The RatRig Discord chat inspired me to alter the design. 41 | 42 | ![Minty Trebor](minty-trebor.jpg) 43 | 44 | # 3. Safety remarks 45 | 46 | **Please use high-end stranded and shielded 24AWG RJ45 cables for safety and reliability.** 47 | 48 | **Please use 16AWG stranded wiring for crimping to high current JST-VH connectors.** 49 | 50 | Low current PCB traces are 0.5mm and can support at most 1A of current, although RJ45 wires of 26AWG size are rated for 350mA per wire, it is not recommended to pull too much current with such thin wires. The PCB does not contain any fuses or diodes to protect wiring or devices. 51 | 52 | High current PCB traces are 3.00mm and can support at most 3.9A of current, and possibly more because the traces are doubled on both sides. **High current traces have only been tested up to 2A. Please be warned and use at your own risk.** 53 | 54 | **Do not** connect a heater cartridge, or high power fan to the low-current JST-XH/RJ45 connectors. It is only designed for low-current devices and you will have a bad day if you decide to pull more than it can handle. 55 | 56 | **Do not** connect anything other than a μ3D module to the RJ45 cables. It does not use any known standard pinouts and will likely destroy any "ethernet" devices you connect (laptops, switches, IP cameras, etc). 57 | 58 | **Do** add your own fuses to protect your wiring and devices. 59 | 60 | **DISCLAIMER: We are not responsible for accidents or problems caused by your use or misuse of these modules.** 61 | 62 | # 4.

[Alternate wiring](#4-alternate-wiring) 19 | 20 | ![PCB board render](pcb-board-render.png) 21 | 22 | # 1. Wiring a PWM fan 23 | 24 | This PCB module is designed for 2 or 3-wire fans (ground, voltage, PWM signal). 25 | 26 | **WARNING:** DO NOT try to control the fan speed of a 2-wire fan. It should/must be _always on_ (i.e: running 100% all the time). 27 | 28 | Simple 2-wire fans only require a ground and voltage wire: 29 | 30 | * If it's a low-current fan (less than 1A), it should be wired to the small JST-XH connector labeled "HOTEND FAN" (pins 1 and GND) or "PARTS FAN" (pins 2 and GND). 31 | 32 | * If the fan is a high-current fan, the voltage and ground should be wired to the larger JST-VH connector labeled "PARTS FAN" (pins a and b). 33 | 34 | A 3-wire fan with a PWM signal should have the PWM signal wired to the smaller JST-XH connector labeled "PARTS FAN" (pin 1), while the voltage and ground should be wired to the larger JST-VH connector labeled "PARTS FAN" (pins a and b). 35 | 36 | # 2. Wiring a heater cartridge 37 | 38 | The following wiring example is based on a _50W E3D V6_ which has a maximum current draw of 3.9A@12V, 2.8A@24V. 39 | 40 | The high-current PCB traces (3.0mm) should theoretically support up to 3.9A of current with a 5deg C temperature rise (tested up to 2A), and the JST-VH connectors can support up to 10A. 41 | 42 | Since the JST-VH connector labeled "HEATER" (pins c and d) is not electrically connected to anything else on the PCB, it should be safe to wire the heater cartridge directly to those pins. The heater cartridge wires do not have polarity, so they can be wired to `c` and `d` in any order. 43 | 44 | # 3. Testing connections 45 | 46 | After soldering all components to the PCB, a good way to ensure there were no mistakes is to perform an electrical continuity test using a multimeter. 47 | 48 | One probe should touch a pin on the back of the RJ45 connector, and the other probe should touch the corresponding (numbered) pin on the JST-XH connector. For example: pin 1 on the left RJ45 should match pin 1 on the "HOTEND FAN". It should beep and/or light up to confirm the circuit is closed. Also make sure pin 1 doesn't match with pin 2 or other pins (if it does then you have a short / solder bridge). 49 | 50 | For testing the JST-VH connectors, simply place a probe on corresponding (lettered) pins for each device. For example: pin e on the left "THERMISTOR" connector should match pin e on the right "THERMISTOR" connector. It should beep and/or light up to confirm the circuit is closed. Also make sure pin e doesn't match with pin f or other pins (if it does then you have a short / solder bridge). 51 | 52 | One final thing to test is connectivity between two PCBs over the RJ45 cables. This should be done _before_ connecting actual devices. 53 | 54 | As in the example above, pin 1 on the left RJ45 (on one PCB) should match pin 1 on the left RJ45 (on the other PCB). Do this for all 8 pins on both RJ45 connectors. 55 | 56 | Perform a similar test with the wiring between both PCBs over the high-current wires (you're using 16AWG, right?). 57 | 58 | --- 59 | 60 | * [EXPLAIN](EXPLAIN.md): learn the story behind this PCB, safety information, and OSHW 61 | * [REFERENCE](REFERENCE.md): learn about the pinouts, trace widths, and other technical information 62 | * [TUTORIALS](TUTORIALS.md): a quick guide to **get started** using this module 63 | 64 | # 4. Alternate wiring 65 | 66 | In the situation where you also want to wire an endstop, thermistor, and have PWM control over the parts fans, all through the RJ45 cables, there is an alternate wiring scheme which can be used. 67 | 68 | The idea is to use the ADXL pins **after tuning with the automatic [Input Shaper Calibration](https://www.klipper3d.org/Measuring_Resonances.html#input-shaper-auto-calibration)**. The ADXL does not need to be wired permanently, and it won't be used while the thermistor or fans are on (they'll cause too much noise), so it is possible to re-use those pins once calibration is complete. 69 | 70 | Simply follow the wiring charts below. 71 | 72 | ### Alternate 1 73 | 74 | **Left side** as viewed from the front: 75 | 76 | | Pin number | Label | Device | 77 | | :----: | :---- | :---- | 78 | | a | PARTS FAN (high current) | unused | 79 | | b | PARTS FAN (high current) | unused | 80 | | e | THERMISTOR (high current) | unused | 81 | | f | THERMISTOR (high current) | unused | 82 | | 1 | HOTEND FAN | Hotend fan + | 83 | | - | HOTEND FAN (GND) | Hotend fan - | 84 | | 2 | PARTS FAN | Endstop + | 85 | | - | PARTS FAN (GND) | Endstop - | 86 | | 3 | ADXL (GND) | unused | 87 | | 4 | ADXL | Thermistor | 88 | | 5 | ADXL | Thermistor | 89 | | 6 | ADXL | Endstop signal | 90 | | 7 | ADXL | Parts fan + | 91 | | 8 | ADXL | Parts fan - | 92 | 93 | ### Alternate 2 94 | 95 | **Left side** as viewed from the front: 96 | 97 | | Pin number | Label | Device | 98 | | :----: | :---- | :---- | 99 | | a | PARTS FAN (high current) | unused | 100 | | b | PARTS FAN (high current) | unused | 101 | | e | THERMISTOR (high current) | Thermistor | 102 | | f | THERMISTOR (high current) | Thermistor | 103 | | 1 | HOTEND FAN | unused | 104 | | - | HOTEND FAN (GND) | unused | 105 | | 2 | PARTS FAN | Endstop + | 106 | | - | PARTS FAN (GND) | Endstop - | 107 | | 3 | ADXL (GND) | unused | 108 | | 4 | ADXL | Hotend fan + | 109 | | 5 | ADXL | Hotend fan - | 110 | | 6 | ADXL | Endstop signal | 111 | | 7 | ADXL | Parts fan + | 112 | | 8 | ADXL | Parts fan - | 113 | 114 | # License 115 | 116 | μ3D: RatRig V-Core 3 EVA wiring over RJ45 and documentation © 2021 by [Alexander Williams](https://a1w.ca/) is licensed under [_CC BY-SA 4.0_ (Attribution-ShareAlike 4.0 International)](https://creativecommons.org/licenses/by-sa/4.0/). 117 | -------------------------------------------------------------------------------- /docs/README.md: -------------------------------------------------------------------------------- 1 | # μ3D: Documentation 2 | 3 | ### RatRig V-Core 3 EVA wiring over RJ45 4 | 5 | A toolboard that mounts on a 3D printer hotend assembly to enable wiring over RJ45. 6 | 7 | ![PCB with EVA mounts](pcb-connectors.jpg) 8 | 9 | **DISCLAIMER: We are not responsible for accidents or problems caused by your use or misuse of these modules.** 10 | 11 | --- 12 | 13 | * [EXPLAIN](EXPLAIN.md): learn the story behind this PCB, safety information, and OSHW 14 | * [HOWTO](HOWTO.md): more detailed information on testing and wiring patterns 15 | * [REFERENCE](REFERENCE.md): learn about the pinouts, trace widths, and other technical information 16 | * [TUTORIALS](TUTORIALS.md): a quick guide to **get started** using this module 17 | 18 | # License 19 | 20 | μ3D: RatRig V-Core 3 EVA wiring over RJ45 and documentation © 2021 by [Alexander Williams](https://a1w.ca/) is licensed under [_CC BY-SA 4.0_ (Attribution-ShareAlike 4.0 International)](https://creativecommons.org/licenses/by-sa/4.0/). 21 | -------------------------------------------------------------------------------- /docs/REFERENCE.md: -------------------------------------------------------------------------------- 1 | # μ3D: Reference 2 | 3 | ### RatRig V-Core 3 EVA wiring over RJ45 4 | 5 | A daughter board that mounts on a 3D printer hotend assembly to enable wiring over RJ45. 6 | 7 | --- 8 | 9 | This document provides technical information about this module. 10 | 11 | **DISCLAIMER: We are not responsible for accidents or problems caused by your use or misuse of these modules.** 12 | 13 | ## Menu 14 | 15 | 1.

Order the PCB kit 30 | 31 | If you haven't purchased the PCB kit already, now's your chance: 32 | 33 | [Buy from Tindie](https://www.tindie.com/products/24538/) 34 | 35 | [![Buy a kit](https://d2ss6ovg47m0r5.cloudfront.net/badges/tindie-mediums.png)](https://www.tindie.com/products/24538/) 36 | 37 | --- 38 | 39 | # 2. Solder the components 40 | 41 | ![PCB top view](pcb-top-view.jpg) 42 | 43 | **Note:** Please use lead-free solder for all components. 44 | 45 | **Note:** Before soldering, please ensure there is proper ventilation, and wear a mask or use a fume extractor if possible. 46 | 47 | ### Test-fit components 48 | 49 | Before soldering, test-fit all the JST-XH and JST-VH connectors to confirm their final location and placement. This step is very difficult to get wrong. 50 | 51 | ### Solder time 52 | 53 | 1. Start with the smaller JST-XH connectors. Insert all the connectors and cover them with masking tape or 54 | kapton tape so they don’t move, then flip the board and solder them carefully. 55 | 2. Solder the larger JST-VH connectors next. Again, cover them with tape so they don't move. 56 | 3. Finally, solder the RJ-45 connectors. Insert the RJ-45 connectors then bend the two side pins for stability. 57 | 58 | ### Verify your work 59 | 60 | It's always a good idea to verify each solder connection's continuity with a multimeter, and ensure there are no bridges with nearby pins. 61 | 62 | See the [Testing Connections howto](HOWTO.md#3-testing-connections) to learn more about testing the solder connections. 63 | 64 | --- 65 | 66 | # 3. Crimp the connectors 67 | 68 | Crimping connectors can be time consuming and error-prone. For the best results, it's recommended to have a **good** crimp tool such as an _Engineer PA-21_ and _Engineer PA-20_ for larger crimps. 69 | 70 | ![Engineer PA-21](engineer-pa21.jpg) 71 | 72 | Also ensure you have the correct size wires: 73 | 74 | * JST-XH crimps support wires 30AWG to 22AWG. 75 | * JST-VH crimps support wires 22AWG to 16AWG. 76 | 77 | Lower gauge (ex: 16AWG) can support higher currents compared to higher gauge (ex: 22AWG). 78 | 79 | **Note:** Make sure you don't shorten wires too much, leave some room for mistakes and future changes. 80 | 81 | The PCB kit includes one extra crimp per PCB. That means you're free to make a mistake, but only one ;) 82 | 83 | --- 84 | 85 | # 4. Connect the devices 86 | 87 | ### Wire the devices 88 | 89 | Wiring devices, such as the thermistor, fans, probe, etc, can be irreversible. If a mistake was made during crimping or soldering, it **could destroy your devices**. 90 | 91 | **Note:** Make sure the 3D printer **is off** before connecting devices for the first time. 92 | 93 | ### Wire the RJ45 cables 94 | 95 | Connect the RJ45 cables between the two PCBs. 96 | 97 | **Note:** Please use high-end stranded and shielded 24AWG RJ45 cables for safety and reliability. 98 | 99 | ### Mount the PCBs 100 | 101 | Make sure to mount the PCBs to your electronics panel and hotend using the grounded M3 mounting holes. 102 | 103 | Congratulations! If you've made it this far, then you're almost ready to start 3D printing. 104 | 105 | --- 106 | 107 | # 5. Start printing 108 | 109 | Turn on your 3D printer, and make some final verifications: 110 | 111 | ### Verify temperatures 112 | 113 | Ensure the wires and cabling aren't getting hot. They should not feel hot after simply turning on the printer. If they do, you might have incorrect wiring and this **could be dangerous**. 114 | 115 | ### Verify voltages 116 | 117 | Ensure the voltages to each device are correct (ex: 24V for the thermistor, 12V for the fan, etc). 118 | 119 | ### Make a test print 120 | 121 | Make a test print, while checking the temperatures of all wiring during printing. Everything should feel _normal_. Smoke is a bad sign, fire is a really bad sign. It's a good idea to avoid those. 122 | 123 | See the [Safety remarks explanation](EXPLAIN.md#3-safety-remarks) to read more safety recommendations. 124 | 125 | --- 126 | 127 | Now that you've
