Im running GBRL Mega 5x with Rambo support. Everything was working except my laser. In trying to change the PWM pin , i have lost my X2 and Y2 stepper movement. I tried reflashing with original firmware. Still no stepper movement. I swapped cables in the control box. Both stepper move but the original two stop. where do i go next?
OK don’t ask me why, but i reflashed the rambo with Marlin. Verified everything was working. Pass. i then reflashed Grbl mega 5X. Somehow everything except the laser is working now. Well back to trying to kill it again. Has anyone successfully installed a Aenbuslm laser module on their Rambo 1.4A?
