RE: [CAD_CAM_EDM_DRO] Matching Microsteps to moters

Hi, Dale:

Although I'm not the expert that Mariss and the others are, I've worked with
Compumotors a few years back. I was told that the motor's basic step rate is
the same 200 step per rev that many of the others are, but that the motors
are manufactured to close tolerances and matched to the controller.

Regarding your X language controllers? Does Compumotor make a similar
motor/controller that uses step and direction? If so, you might be able to
swap the EProms in your driver for EProms from a Step/Direction drive. We
once worked with our local Compumotor rep to get EProms to change an RS-232
interface controller to Step/Dir. It might work for you.

|Hi Jon, Tim, Mariss, others,
|All this talk about microstep accuracy and smoothness has gotten me
|thinking about my compumoter steppers. My Moters are compumoter c
|series which came as part of a package which included the moters and
|cx drivers, which I can't use for my project since they use
|compumoter X language instead of step & direction signals. They may
|have provided me with a valuable piece of info however. These drivers
|are 12800 microstep drives. The Geckos are as I understand it are
|2000 microstep drives (200 steps x 10 micro per step if I'm thinking
|correctly). This didn't concern me untill now as I have heard so much
|about how smooth the geckos make your machine perform. Now I see that
|Tims API drives have a 12800 setting, and after reading the previous
|posts I wonder if these might run smoother with my moters that were
|designed to run with 12800 microsteps. Will my moters run poorly with
|Geckos? With everything Mariss does here, including designing
|circuits for plasma controls etc. I prefer to purchase Geckos, But if
|my moters are not going to like them, maybe I should grab some APIs
|while I can, and next time purchase moters that will be compatable
|with geckos.
|Any Thoughts from the experts?
|Thanks, Dale
