What could be the reason that stepper is losing steps at very low speeds? On
my machine I have servos for XYZ axes (Pico control), and two (leadshine)
hybrid steppers for rotary axes, which I found out that they are loosing steps
at very low speeds. I think it might not be related to driver
Make sure you dont power down, stay at full power, you did not mention
microsteps, Are you expecting higher resolution and accuracy than is
possible with a stepper.
You can see regular accuracy error due to the stepper when I tested a
linear axis

It could be that the drives are of a type that switches to a standby current
when idle. (Though if that always caused problems they clearly wouldn't do

Microstep is set to 4000, gearing is 21:1 and it has very very small backlash
and its well above my accuracy needs. The thing is that at very low speeds (ie
50deg/min on motor side) it loses so many steps that the error is more then few
degrees after reaching final position...
Make sure you
