I recently had two print failures on my Ender 3 Neo. In both, it looked like the part came free from the heated build plate after about an hour or so of printing. Both had good starts in the first 15 minutes or so. I had a successful print finish two days ago.
It has been hot and humid here today, and my printer is in a non-AC shed not connected to the house.
I’m wondering if I should wait to kick off the next print until this evening when it should be cooler. Do I need to clean the build plate? I’ve not done that at all, other than make sure these isn’t any filament left on the plate when it finishes.
UPDATE: It’s apparent the problem isn’t the heat, but the fact that I haven’t cleaned the build plate since… well, ever. Adjusting the title to reflect that.
Your print doesn’t come off from heat, its the opposite. If you never cleaned the build plate that is 100% the problem. I clean mine before every print.
OK, good to know – just did an alcohol/dish soap wipe and restarted the print, will check it in a bit, and do the cleaning after every print.
