Hi all -
I had a pretty bad clog on a print a few days ago, and the plastic wrapped around the nozzle and the bottom of the aluminum block.
I’ve taken it apart, cleaned it all, and re-assembled, but now the heating rod is not heating up.
I viewed the tutorial videos on YouTube, and am trying to remove the heating rod and temperature sensor to check for open circuit, broken wire, or other issues, however the ‘set screw’ won’t come out - the one that faces the bottom of the aluminum heating block, next to the nozzle, which holds the heating rod in place.
I think plastic got all into the set screw location during the clog, so it’s really stuck in there. I’m a pretty strong guy, and it’s not coming out of there with the allen wrench. I’m pushing as hard as I dare - any more and I’m afraid I’ll just strip it. The person in the video, by comparison, seemed to be able to use almost fingertip pressure to get the screw out and remove the heating element.
Any ideas on how I can get that screw out?
Should I just order a replacement block/heating element/temperature sensor from Dobot?
Thanks,
Aaron
