Hey I just got an easydriver stepper controller and stepper motor off of sparkfun and I’m having some trouble with it. I’m using EMC linux and I’m trying to configure it properly but obviously, I’m new at this. So whats the voltage that the step and dir should see? Anyway here’s what I have to configure:
Step time
Step space
Direction hold
Direction setup
driver microstepping (i set it to 8)
acceleration
velocity
I could definately use the help if anyone has any insight, thanks in advance.

The EasyDriver boards need 5V for the step and direction signals, so they should work fine with any normal parallel port. I’ve never tried the ED boards with any of the PC CNC software (TurboCNC, Mach3, EMC, etc.) But they should work just fine.
The EDs are set to use 8 microstep mode in hardware, so you should configure your software that way. I would start with accel and vel very low, and ramp them up until things stop working. I know that Mach3 has a motor configuration screen where you can play with all of this stuff in real time and watch the motors run to see what parameters work and which don’t. Is there such a thing in EMC?
For the step time and step space, I’m assuming those are minimums. I’d use 50us for each to start with (for a 10KHz step rate). For direction hold and setup, use something similar - maybe a bit longer like 1ms. You can always start slow and speed things up when you see that they are working right.

EMC has something similar. I’ll give it a try and let you know how it pans out, thanks.
