Precision Matthews PM-1030 Lathe - Clough42 Electronic Lead Screw

thingiverse

This is one person's implementation of the Clough42 Electronic Lead Screw project for a PM-1030 (also PM-1022) lathe. Clough42 has an extensive playlist for this project on YouTube at: https://youtube.com/playlist?list=PLDlWKv7KIIr90ZZ7Zqt-ge5nVVdS3WVgg I strongly encourage watching this entire series for details and use my writeup for PM details and quick reference. Here's a link to his GitHub repository with the code and supporting documentation: https://github.com/clough42/electronic-leadscrew Full set of notes and links to James Clough's orginal work on YouTube and GitHub are all in the file Clough42 Electronic Leadscrew.pdf. Dimensioned drawings of the mount and key adjustments to the code to match the PM-1030 feed gearing are all covered in the pdf. Please note that my implementation uses parts designed and posted to ThingiVerse by nstahl at https://www.thingiverse.com/thing:4732492 The TI LaunchPad bracket and grommet designs are mine. For the cable grommet, that was my solution to a pre-built cable with a large connector. One end of the stepper motor encoder cable has a screw together headshell that can come off and allow the cable to pass through a hole of about an inch. Print a pair of the half grommets, put those together around the cable and use screws to mount to the electrical box. The TI LaunchPad can be mounted on the bracket with #2 hex head screws similar to those used to mount servos in RC model airplanes. I used nylon washers to prevent the chance of making electrical contact between the screws and any trace on the PCB.
