When I press the switch for one second there is a horrible grinding noise from the stepper motor in the 3D chameleon. Is this normal?
When I tried printing, the firth thing that happens is the grinding noise, then the chameleon unloads one of the filaments so that it ends up far away from the y, then the printer starts "printing" with no filament loaded. I used the gcode generator. Not sure what else to do other than perhaps changing the code to press the switch 3.5 seconds to load instead of 5.5 seconds.
