Hi !

I recently salvaged a prusa i3 so I could use some of its parts in a "drawing robot" , but the steppers shake intensely and do move (the coils are connected properly) but the shaking is
so extreme that the entire thing just moves when I put it on the ground , and this sort of shaking was nonexistent when the motors were on the prusa .
I have tried 1/16 and 1/32 microstepping (because switching to 1/32 saved me from this shaking once in the past) but nothing changed. I also tried fine tuning the potentiometer on the
driver but it shakes no matter how much current it gets.
I also have another issue regarding grbl itself but I have no idea where to ask , because I believe this forum is about bigger machines than what I am working on ?

thanks in advance !
