every so often, my print bed rises too high and the print heads dumbly try to position themselves over the bed but cannot because they hit the side of the print bed instead. by faking a print and turning off the machine multiple times, the print bed gradually lowers and the print heads are eventually able to clear the top of the bed. this is unacceptable.
how do i tell the printer to lower or raise the print bed? i see no option on the menu to do so.
Make sure your bed is always in the printer when you do any manipulation with filament (load, unload). In the beginning of every operation printer searches for bed level with left extruder microswitch. If there is no bed at this moment Z coordinate will be wrong – about 5 mm lower. And when you put the glass back the extruder will hit the glass. That’s how we broke the right microswitch once.
Sorry if it is not your case.
i just upgraded to the latest firmware and now my printer is hosed.
image 000 = missing icon
image 001 = missing icon. no files are listed and the data card has multiple gcode files
image 002 = backing out of the utilities calibration screen comes here with no way to exit
image 003 = neither of the filament buttons respond
i need to get operational again asap.
