Y and Z axis seem to be locked up

Hello everyone,

Wondering if anybody ever had issues with their motors locking up. When everything is turned off, all axis’ move freely. Once I power up the SLB and connect to Gsender, the Y axis and Z axis motors lock up and do not move. The X axis moves, but slower than normal and in the wrong direction. Left is right and vice versa. Ive tried to uninstall and reinstall gsender but I am getting the same results. I’ve tried to switch out my cord to connect the machine to my computer and still nothing. I swapped motors to the X axis, and all motors turn. I am thinking there is something wrong with my SLB?
