Universal Geeetech 3Dman Extruder Printers Review

The seller didn't even try to make it presentable. The extruder was packed in a dirty plastic bag. I took it apart to get the gears I needed for the project and found some old thread on the teeth of these very tired gears. Oh well.

I had no setup issues after printing the mounts for my Ender 3 Pro. AFTER correct execution of the electronic steps and voltage setting. I haven't had a single issue with slippage or filament extrusion. In my opinion it was a quality purchase that helped to better understand my new hobby.

You need to put a small washer on the bottom of the gear on the lever that rotates in the open position to restrict it or it will pop out if you print quickly with the case. This resulted in 2 failed prints, both after an hour and a half to two hours. I was printing with a 0.8 nozzle, so quite a bit of filament was wasted in that time. If you add a tiny shim to keep the gear on the opening arm from playing, this won't happen again. Have spent 100 hours on it since then and it works flawlessly…
