Title: Mixing Stepper motors with servo's
Post by: Jimster on January 08, 2014, 12:30:46 PM
Hu Guys,
I'm not sure if this is possible (I think not), but I thought I would check first. I want to add a 4th axis to my machine, I'm currently using a CSMIO IP-A controlling 3 analogue servo drives. Could I add a stepper motor controller (parallel Port base) just to control the 4th axis???

Thanks

Jim

Afraid not, the IP-A can only control analogue command drives and you can only use one motion controller with Mach.
There may be stepper drives out there that can accept analogue commands but I have never seen any.

Thanks for clearing this up for me. Could I use something like this for a 4th axis with a servo drive?

That has been listed more than a few times on eBay and I remember looking at the specs and deciding it was not suitable for me. I cant recall exactly why but you can find info regarding it via google.
