I have a TAZ5 that I just purchased off ebay (yes another one of those poor used and abused TAZ5 specials you find no-where else!)
Besides the physical damage to the frame it endured during shipping (what else is new), I’ve been trying to evaluate the electronics side of it.
When I power the printer on, the X Y and Z displayed on the LCD screen cycle between "X,Y,Z and a ? mark. Does anyone know what that means?
I’ve checked the wiring and the control board, and it appears physically to be in ok shape.
With the build in controls, I can move the X, Y and Z axis steppers, and the heated bed and extruder heats up… BUT… I cannot get the extruder stepper to do anything. I’ve checked the wiring and it’s ok. I’ve swapped in a known working print head, and the stepper to extrude filament will not do anything when told to do so from the control panel.
Any thoughts?
Thanks for your time and reading about my woes…
