I’m having issues with my extruder motor. It stopped working all of a sudden at the start of a print and refuses to operate now. I’ve tested the stepper motor by plugging in the x axis cable and operating the x axis and that’s fine. However, plugging in the extruder motor cable into x axis stepper has no reaction, even when extruder is up to temp. I’ve checked the cable and it has continuity. I’ve also checked the interface PCBA and I have continuity between the large multi pin ribbon cable housing and extruder connector housing. The rest of the components on the PCBA are working which would suggest the ribbon cable is fine. So it seems to suggest there’s an issue with the main board, possibly a dead driver?
Has anyone seen this issue before? Is there a fix, aside from replacing the main board? Finding a replacement main board for my Aldi Balco printer is difficult, I’ve only seen v5.1 and v5.4 boards online, struggling to find the v5.2c board that I have.
Any help would be greatly appreciated! I really hope I don’t have a dead printer on my hands
