Sounds dumb. Should be.
I JUST PID tuned this v3 Se. Trying to print at 250. Upgraded hot end heats to 250, drops to 237, heats to 250, drops to 237. Never starts printing. Again, just tuned it (again) 10 minutes ago.
So then… how do we print?
Ha! Tricked it. Adjusted temp to 220 and it started. Bumped back to 250 and while it’s not holding temp, it is actually printing. This is a duct tape fix but that’s what I get for cheaping out on the Bambu.
