Hi,
Please help!
Im new to CNC machines and just bought an Industrial Artesan 4x8 used for 3 months. My Z-axis is just making a buzzing sound and not spinning when I try to hold pag up or down keyboard keys. I was told to change the stepper motor controller then the power transformer and the Z was still not working(X and Y axis work fine). I plugged the Z stepper motor into A different controller and then the Z works fine. I was told to check all boards inside the control box for burned components but all are fine. The “life help support” refused to help since I didnt buy directly from them even though the machine is technically brand new. The only part that I haven't changed yet is the one on my 2nd photo uploaded here.
Thank you
