So, I got the lower half of the left forearm printed out. My ender 3 pro decided to be a real prick about printing it out. as I reached about 50% completion I had to give the printer some time to relax because it was having thermal runaway issues. I don't quite know what caused it, it could have something to do with my ender 5 being in the same room and also running. On top of that, there is a lot of inconsistency in the print (straight lines ended up all wavy) whereas the other forearm was perfectly fine. the other forearm was printed entirely on the ender 3 pro. maybe the gcode was bad or something, I don't really know. I'll have another update soon since the left bicep is almost done!
EDIT: There was also a smidge of lifting on one part of the base
cheers!
