Hey guys,
The wife bought me a chuck style rotary and I am needing some assistance with setting it up in LB
Seller provided these number but I am not exactly sure what I need to put in the rotary setup sections…

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.
