@rubensx Take a look at this post, you need to measure the Vref (when motors are not running) and adjust carefully. Also check the belts are not too loose or tight and the axis are not sticking (must move freely).
@Dominykasssx I can't give you an exact value, but I would start with a 10kohm (1/8W would be ok) and if the laser doesn't turn off you go lower until it does. If it's not turning off by ~1kohm then you probably won't find a solution that works.
Say a 2.2kohm turns the laser off when disconnected, then you must check that the laser turns on with software control (TTL input connected).
