I bought an ender 3 a few days ago, and when i tried to calibrate the heatbed, the metal clamp fried one of the stepper drivers. Becuse i cant change it on the factory motherboard i had to buy a new one, so i bought the MKS GEN L motherboard. When i was trying to make it work, the motor just vibrated. I made a huge mistake and then put a drv8825 stepper driver in the board but backwards. That maby kriszmen66 - Controllers
