Hello,

I have a DIY machine with arduino one and I want to make an upgrade by changing the arduino.

the problem is that, my machine has a separate power supply and is 12v and as I saw mini gerbil works 24v, I would like to know which Power Supplies I can buy or wha is your recomendations.

Hi, 12V DC still works fine for the Mini Gerbil. The step sticks A4988 work from 6V up to 30V DC.

Cheers, Paul

Hi, pls can you give me a bit more details since it's very hard to understand what is happening? Can you measure 12V DC on the stepper driver (Between VMOT, GND)? Can you manually move the gantry or is it firm in position hold by energised motors?

When you unlock the controller via command $X, can you give it a few G code instructions like G92, G0 X10, G0 Y10, G0 X0, G0 Y0 etc. Do the motor step 10mm?

G92=zero out the position

G0 (G zero) X10 means goto position X=10mm
