Hello,
I have finally completed my 3DR, all seems to be working correctly, levelled the bed, so far so good.
I have hit a problem with printing. When I print everything looks fine, it heats up then starts to print, the extruder motor starts and pushed PLA through. But the PLA doesn't go into the hot end, it just starts collecting at the other side of the extruder. If I manually add a little force to the pla towards to hot end it starts to ooze fine, but as soon as I stop it doesn't push itself through.
Am I missing something, any help would be appreciated. What is the usual mechanism for pushing the pla from the extruder end to the hot end (with a gregs extruder setup)?
