+ | ===== Dead Stepper driver - workaround ===== | ||
+ | i recently printed a quite tall structure over night. it tunred out, that the screws of the z-axis wheels did not clear the mounting bracket for the extruder. as a result of the z-axis missed most of its steps during several hours and was jammend. | ||
+ | sadly it turned out that after this the Z-axis stepper driver was broken. when i moved the z-axis the stepper would randomly move forward or backward or just humm. i've tried to adjust the potentiometer but with no luck. | ||
+ | |||
+ | as a workaround i changed the marlin config, so that it's now using the E1 (second extruder, which i don't have) stepper driver in place of the z-axis. i could simply move the molex connector over from Z to E1 and continue to print. | ||
+ | |||
+ | to implement the workaround, i had to start my Arduino IDE, open the Marlin project and edit the '' | ||
