Very little time tonight to work on the #ElectronicLeadScrew. Just wired up the 4-pin aviation connector for the toolpost grinder motor. Right now using only two conductors for DC, but this lets me upgrade to 3-phase ESC/VFD later if I want to. Also modeled spacers to hold the M6 mounting screws captive to make installation easy and avoid scratching the lathe with the mostly-flush screws.
@mcdanlj tool post grinder? Sounds like advanced electronic leadscrew usecase.
I got my Arduino setup pretty optimized. Going to try threading this weekend. Bought a slightly better driver to see if I can squeeze a bit more power out of my small motor before i upgrade that. By the numbers I should be about to 16x microstep 1mm travel per rotation easily up to 1000rpm which is wildly more that I need.
@makergeek The toolpost grinder is not really related to the ELS. It's just that I'm picking power off the lathe's primary box, and I want a toolpost grinder. So I'm putting the servo power supply and the toolpost grinder power supply both behind a secondary contactor that is energized when I arm the lathe, and the box is sufficient for both the ELS and the (future) toolpost grinder.
