Hello,

I'm retrofit an old cnc lathe :

www.usinages.com/threads/retrofit-tour-j...micro-tour-2.142903/

but I can not find best parameters for Step motor controler DM542A(Step Time,...) and my stepper motor. (speed, acceleration...)

I can not used the "test Axis" in stepconf wizard because I use Raspbery PI and not parallel port.

In attached file you have my ini and my hal file.

Can you help me please.

BR

This manual should give you some base figures:

This is the Linuxcnc manual for tuning:
linuxcnc.org/docs/2.8/html/motion/tweaking-steppers.html

Accel & Max Velocity are a machine by machine thing. Sound & feel help in this respect. I backed my machine down so I had some headroom. From what I remember it could go scary fast.
