Hope someone can help

What kind of controller are you running?

Ruida controller. I have a yellow and black 7050, 50w. I unplug the Y axis from a 4 pin plug and plug the rotary in to it.

So far, the two important bits I see are 1.8 degree step angle (200 steps per rotation) and 3:1 pulley reduction. Without any micro-stepping, that’s have 600 steps per rotation.

The Y axis driver in your Ruida will be set to use micro-stepping - likely 10:1 or 16:1, so you could try 6000 (10:1) or 9600 (16:1) as an initial guess for the Steps per Rotation value in the rotary screen.

Choose the chuck style rotary, and then, as a test, set an arbitrary value for Circumference, make a rectangle that’s that tall, and run it using ‘Current Position’ mode on the rotary. It should make one perfect rotation and then go back again. If it doesn’t, the steps count is off. If it doesn’t make a full 360 rotation, you need a larger step count. If it overshoots, you need a lower one.

Does that make sense? If any of that isn’t clear, let me know.

Arbitrary value like 254mm?

Yes, pretty much any number that’s smaller than the Y axis length of your machine. I usually use 100mm just because it’s easy.

ok, cool, Thanks!
