Using the correct connection and everything appears to be working as intended.
problem: the heated extruder got nothing coming out. The feeder try pushing hard and then the PLA would skip back because the head is blocked.
I tried sharped the PLA head but still it just don’t feed into the header.
From the software the head is 200’C already before feeding start.
I tried using flashlight to see the head but the hole is black, i am not sure is it by design or part of the PLA is already blocked inside.
