Re: Vibration at low speed
If I were you and spending $5 on a microstepping module meant the difference between getting the job done quickly and many hours of essentially wasted effort, I'd spend the $5. If your boss is so...

Hi all, I have a power stage proving power to a stepper motor. [ftp.phytron.de] This power stage, the MSD Mini Powerpack 172-140, outputs a constant 140V DC, with no user-friendly way to reduce it. My...
View ArticleRe: Resisting Voltage from Power Stage
Stepper motors' torque specs are based on current, not voltage. The voltage value is simply the current x winding resistance. The current you set in the driver is the average value that will be...

Thanks stephenrc, that kind of worked, I can get up to 12800 steps/mm now. For some reason auto home on z has now stopped working, it just drives straight through. Maybe I'll try to 1/8 step at 6400?
