At 1TPI that motor would have to fly the lead screw would be spinning much faster than the spindle. I'm not sure that is possible even if you ran a...

First of all the encoder count should be 4096. its 4 time the pulse per rotation. What is your stepper drive motor ratio you have it set up for a...

First off you have to use toothed timing belts for everything. It has to hold exact position with no slip. The drive should be the larger HTD 3m by 10mm...

I made a carrige stop and an emergency stop on my lathe, not for threading but fot safty and turning to a rough shoulder. It works very well for that...

As I mentioned I cut the enable wire going to the servo, this stops the motor quickly. It will stop every time within .002 of the shoulder. I ran my...

Direction wire wont do it so try the pull wire, just disconnect it at the els board and see what happens. If it doesnt stop it try the red +...

Does it show RPM on the display?? The display boards thyem selves are quite finicky. My first one didn't work properly. you can buy them on Amazon, quite inexpensive. Try...

I am sure the encoder can be diagnosed with a scope although I'm not sure what you would expect for a good one. but I do believe there were some...

https://github.com/clough42/electronic-leadscrew/issues/246#issuecomment-1480478130 How are you driving your encoder?? My suspicion would be a slight offset in the 1 to 1 drive ratio. Mark the position of the spindle and the encoder....

I have no idea of how to properly test the encoder although i believe i once found a youtube video but you needed an oscilloscope for proper diagnosis. this is...
