looks very good i hope it will work on my chiron
Solid build, feels sturdy and nice. Gears are all metal. Gears felt a bit rough first and one gear was leaving small metal bit (I'm guessing it's the coating). Scraped it a bit and turned the gears and finally added some oil. Hooked it to the stepper and it's now running smoothly. It's making little bit more noise than the stock extruder, but not bad at all. On my Ender 3 V2 I had to set E steps via Octoprint's terminal. The Ender 3 v2 controller seems to max out Esteps to 186. So I used gcode command M92 E448 to set the E steps corretly. Then M500 command to save the settings to eeprom. Now it prints very nicely.
