2387 | Since Version 8.3, EAGLE supports Fusion synchronisation.
2388 | This feature will not be available in this version and saving
2389 | the document will break the link to the Fusion PCB feature.
2390 |
2391 |
2392 | Since Version 8.3, EAGLE supports URNs for individual library
2393 | assets (packages, symbols, and devices). The URNs of those assets
2394 | will not be understood (or retained) with this version.
2395 |
2396 |
2397 | Since Version 8.3, EAGLE supports the association of 3D packages
2398 | with devices in libraries, schematics, and board files. Those 3D
2399 | packages will not be understood (or retained) with this version.
2400 |
2401 |
2402 | Since Version 9.5, EAGLE supports persistent groups with
2403 | schematics, and board files. Those persistent groups
2404 | will not be understood (or retained) with this version.

1 | # Smart Touchscreen DRO for Milling Machines

9 | ### Introduction
10 | The Smart DRO is a touchscreen digital readout for milling machines. You
11 | can see in the photos an installation on a Grizzly mill/drill, replacing
12 | the original display head (shown on the mill table). The OEM position
13 | sensors for the X, Y, and Z axes directly connect to the back of the unit.
14 | Position sensors like these are individually available commercially for
15 | mills that do not have them factory installed.
16 |
17 | The Smart DRO can greatly simplify milling from dimensioned drawings. If
18 | you enter the diameter of the tool it can automatically adjust the
19 | display reading by the tool radius. This allows you to cut at the specified
20 | dimension without having to add or subtract the radius offset. Note in the
21 | lower left corner of the main screen (the dark rectangle with a circle on
22 | each side): you can select which side you're cutting so it knows whether to
23 | add or subtract the cutter radius.
24 |
25 | You can enter the diameter of each tool as you use it, but the Smart DRO
26 | can also keep your entire tool library (up to 500 tools) in non-volatile
27 | memory. You can enter the list manually or import it from a flash drive
28 | if you share it with other programs or devices. The Smart DRO will also
29 | calculate feeds and speeds, and it displays the current feed rate when
30 | any of the axes move.
31 |
32 | Another helpful feature is the undo list for changes in the origin of any
33 | axis. If you accidently zero out or set a value to the wrong axis, you can
34 | easily recover the origin even if the axis has been moved.
35 |
36 | The on-screen calculator allows you to include axis readings in
37 | calculations, and copy results back to an axis.
38 |
39 | ### Sensor Compatibility
40 | It is industry standard that position sensors use a 9-pin "D" connector
41 | (like a PC serial port). However, there is no standard for the pin
42 | assignments for the connector! To solve this, the Smart DRO uses a pinout
43 | adapter for each axis. A tiny printed circuit board with a single connector
44 | routes signals to the correct pins. A set of 3 of these PCBs costs just 45 cents.
45 | See the [*Servo* magazine article](https://www.timpaterson.com/articles/Servo/SmartDroP1_P2.pdf)
46 | for more info.

48 | ### The Project
49 | The main component is the 10" LCD touchscreen, specified in the parts
50 | list. This repository includes all other aspects of the hardware design
51 | needed to build this project as shown. These elements include:
52 | - Custom [electronics design](https://github.com/TimPaterson/TouchscreenDigitalReadout/tree/master/Electronics),
53 | with printed circuit board ready for fabrication.
54 | - Enclosure design, using a 3D-printed bezel and machined aluminum back.
55 |
56 | A [separate repository](https://github.com/TimPaterson/Touchscreen-DRO-Firmware)
57 | has the microcontroller firmware and graphics images.
58 |
59 | Here are the critical links:
60 | - The [*Servo* magazine article](https://www.timpaterson.com/articles/Servo/SmartDroP1_P2.pdf)
61 | has complete instructions on how to build it.
62 | - The [Touchscreen-DRO-Firmware](https://github.com/TimPaterson/Touchscreen-DRO-Firmware) repository
63 | has firmware and everything else you need, bundled into a release.
64 | - [Touchscreen at BuyDisplay.com](https://www.buydisplay.com/serial-spi-i2c-10-1-inch-tft-lcd-module-dislay-w-ra8876-optl-touch-panel).
65 | Be sure to select options per the [parts list](https://github.com/TimPaterson/TouchscreenDigitalReadout/blob/master/Electronics/DroPartsList.pdf).
66 | - [Main PCB shared at OSH Park](https://oshpark.com/shared_projects/AQX5MSFg). The
67 | EAGLE CAD for the PCB is included is you want to use another PCB source.
68 | - Pinout PCBs at OSH Park. Pinouts are specified by a 4-digit number where
69 | the digits are the pin numbers on the 9-pin D-connector for GND, +5V, A, & B, respectively.
70 | - [2768 (Grizzly)](https://oshpark.com/shared_projects/TLEyl9I6)
71 | - [2134 (Jing/Jcgs)](https://oshpark.com/shared_projects/ilViDS0E)
72 | - [6724 (Acu-Rite)](https://oshpark.com/shared_projects/GIDBOB83)
73 | - [Tool Library Manager](https://github.com/TimPaterson/CNC-Tool-Library-Manager)
74 | for making tool libary files the Smart DRO can import.
