Extruder motor inner gear not attached

[seso]

Hi , I have a some problems with me extruder motor
1- The inner gear is not attach any more so the motor turns and nothing happens

2- the motor heats up so high while in prints

i glued the inner gear which worked for couple a days but after that it just became lose again due to heat issues i guess

more info is needed. what gear are you referring to? the gear that drives and makes contact with the filament or one inside the planetary gearbox of the stepper?

I had the same problem awhile ago on my newest press about a month after firing it up. After some back and forth with MG support we figured out the gear that drives the planetary gears wasn't properly fastened to the main shaft so the gear... while it still turned would slip down the shaft and no longer make contact well enough with the planetary gears which in turn would cause some funky feeding issues. (it would feed in inconstantly or not at all) Support said I could reattach it with a certain Loctite (can't remember which number variant) to temporally fix it while they sent me out a new motor. I just waited on the new motor so I never tried the fix but in a nut shell..... Just contact support and they will get you going again.

the one inside the gear box i just glued it and printed with it but that would be the second time my main issue right now is the overheating of the extruder motor

The pinions are glues on with loctite retaining compound. Normal operating temp after running a couple few hours is in the 60c range. So fairly warm. 60-70 would Not be overheating. You dont contact support through the forum. Open a support ticket. Instructions should be on the website.

seso,

i bought some loctite 609 (retaining compund) to fix a stepper that had a worn out pinion ... i didn't use for the opposite reason, i count get the old pinion off.
if support dosnt help you, and you cant find the right loctite anyplace, let me know i'll ship this out to you.. even have a pinion gear. i can send with it if needed.
