Hotend gear
I just melted my original gear so I modeled another one and printed in A1 with 0.2 nozzle and now I’m going to test if it will work, 6 walls 80% infill grid
Update: After I ran a 4-hour ABS print, the gear shaft heated up in about 20 minutes and ended up expanding the gear’s hole, causing it to slip. The gear teeth are still in perfect condition, but the printer stopped printing because the gear was slipping. I’ll run another test with ABS and PETG-CF.
