So, I haven’t really needed to ask for help re: 3d printers in a long time, but I have been ramming my head against a wall for the last couple of days and this time I might need some help.
The X axis on a makergear prusa at my hackerspace seems to be exhibiting some “backlash” on the X axis. Except, I’ve tested nearly every form of backlash I can find. I redid the X belting, checked the pulley, idler, they’re all tensioned correctly. Afterwards, I figured it might be the driver overheating and going into fault mode, but it keeps happening the exact same place every time. Nevertheless I replaced the driver, added a big ol heatsink on it, and same thing happens.
I went back to the belt, quadruple checked it, even checked the carriage and its attachment, I can not find any form of mechanical backlash at all on this machine.
This on a ramps 1.3, mega 2560. Can stepper motors “go bad”? It seems the only thing I haven’t attempted yet is replacing the stepper motor. Any suggestions?
