This will help prevent the wheel from inadvertently spinning should the lathe vibrate while cutting. I cut some of the wheel off to act as a counterbalance for the handle (seen below). I made a spinning handle out of a 1/4-20 bolt and a piece of stainless tubing which makes moving the rest effortless 0) I used some of my scrap 1/4” aluminum plate to make a hand crank that bolts onto the existing hand wheel with two bolts.

Original message -From: dbike199 Date: 5/16/22 6:42 AM (GMT-05:00) To: clough42/electronic-leadscrew Cc: Subscribed Subject: Thread and feed rates are to fine (Issue #215) I wound up getting the right motor after wasting alot of time, playing with ratios. I had a similar issue with that stepper motor, as it is only 1.2 degrees per step, and not 1.8 steps like James used. I tried the Trouble shooting recommendations per James Github page but have not solved the issue yet.Īs stated above, the issue seems to be with the correct numbers for the Stepper Microsteps and Stepper Resolution for my servo and driver setup. I believe it is programed correctly as my spindle RPM is very accurate compared to the display when checked with a tachometer.Īll the buttons and display work as they should. G0602 is set with a 1:1 ration on transmission (1 and A) I believe the issue is with the 3:1 ratio of the Hybrid Servo and Lead screw setupģ:1 ration from Servo to Lead screw via pullies (24t and 72t Pullies) The kit came with a 'NEMA23 KL-23-2N-1000Hybrid Servo Motor with one Encoder 1000 line'. All the manuals and specs are on this link. I ordered this stepper and driver setup from Automation Technology. I'm pretty sure that is where my issue is. I played with the setting in Code Composer 9.1.0 but I can't seem to hit the correct combination Stepper Microsteps and Stepper Resolution for my setup. The best I can tell they are 3 times to fine (clue).

The only issue I have is the threading and feed rates are way to fine. I finally received TI LaunchXL-F280049C last week and programed the board.

I have been doing the G0602 VFD and ELS conversions by James videos.
