Z Motors turning on retract/unretract
I'm not trying to cross post, but I'm really being stymied by a problem and I didn't see this particular section before posting to the printing section. On retract/unretract my z motors are turning...

Ok, seems this is a firmware issue after all. There appears to be a bug in Marlin related to UBL. If I disable UBL, the problem goes away.

I'm attempting to replace 1stepper driver on a Mightyboard with a A4988 to which I will solder the pins. As you probably know the pins on the A4988 carrier board as fitted to a mightyboard are...

I'm curious about the max amperage we should use when setting stepper voltages. If I have a stepper motor that according to the specs is rated at 1.2A, at a rated 2V. Do we have to do any conversion...

Don't worry about the coil voltage. Most people use 80% of max. current and calculate Vref accordingly. You've registered 4 years ago, so I won't bother you with links to our Wiki or suggest...

In research of the RepRap Mendel, I found the resolution of this printer to be 100 microns. How many cycles of the stepper motor are required to reach this resolution, and can this be reduced through...

Replacing the steppers with 0.9° versions would double up the resolution. Using smaller GT2-pulleys where possible would help, too ( 16 tooth vs 20 tooth ) Or leadscrews with finer pitch. Then there...

To bad you can't feed the MKS bords from the RasPi. AFAIR, it's 5V regulator is much beefier than the faintharded Arduino stuff.
