Thank you very much, today I unclogged my UM2 nozzle using the simpler version method.
However, I have some questions
1) how do you push the head? Is there any menu to move the head x and y position in new firmwares?
what I did was using the "change material" to have the machine place the head at the front. Normally, at power on the motors are powered and stiff.
2)Similarly, when in the "heat nozzle" menu, the feeder is stiff (motor on). To pull the filament, once I was at 90 degrees, I switched the machine off, and manually pulled the filament. Is there a better way?
