Ortur Laser 1.3 : overheating motor stepper

Soo…I start a simple laser engraving on my Ortur laser. But After like 10 min the 2 stepper motor are really really hot. I make some research and it look like it is a problem of too much electric power on motors. Buuut I can’t find the Potentiometer on the card. And i don’t know where to change that setting on a software like laserGRBL.

So if someone can help. thx Here the scheme of the card.

How hot? Stepper motors can get hot enough to burn you but still be completely within their specs. They do run hot.

very hot. I can’t touch them after 10 min. I have an other machine with the same motor and after 1 hour of engraving they are barely warm. ( I am unlucky 2 machine with the same problem, first one i repair it by adjusting the little Potentiometer on it.)

Ok i will try a run with the hot one. and check if it stop by overheating.

ok soo…it work during one hour without a problem…still hot but work.

I suppose all is OK. Thank for the help Oz.
