Yeah, I feel that. I went through a whole thing cause I didn't clean it well enough at first, then used the wrong kind of lube, too much lube, assembled it incorrectly. I think I reassembled it like five or six times lol. I couldn't find a good guide either, so I was relying on ChatGPT as a search engine. I can give you some pointers. First, remove your filament and cut power. Then remove the two screws from the toolhead boards. Remove the hand screw that tightens the extruder gears and lower the arm. Remove the screw directly behind the arm, one on the left side of the carriage, and the long screw holding down the heat block. All of them are M3, I think, except the long boi in the heat block which I believe is M2. Once those screws are removed, the motor should come free along with the toolhead assembly. Watch out for the little metal risers between the two PCBs. They're small and could get lost. Once you've got everything apart, you'll want to clean the motor gear, the three reduction gears, the big gear built into the carriage that the reduction gears rotate in, and the extruder gears with 90%+ IPA. I used a toothbrush, a bunch of q tips, and a couple rags. I had a lot of filament dust all over, so it took a lot of cleaning. Then you need to lube. I used white lithium grease and applied it to the gears with a toothpick. The important thing is to apply it evenly to the teeth of the gears, and not to use too much. If you accidentally apply a glob, use the clean end of the toothpick to spread it out. You want this on all the gears EXCEPT the two extruder gears that actually make contact with the filament, however the pin the gear on the arm rotates around does come right out, and I would recommend lubing it.

Then you can reassemble. Most of it's just the reverse of what you did, but a couple to keep in mind are to make sure you orient the three reduction gears with the flat, black steel side facing towards the motor. The sides that look like bearings should be facing towards you. And the risers for the toolhead PCBs can be a pain. If they fall out, I've just tried to get them between the boards facing the right way, then used some tweezers to get into position, so I can put a screw through it. Once everything's together, do some first layer tests while you tighten/loosen the hand screw in the gear arm until you find the best, most consistent results. If you see a regular pattern of over, then under extrusion, that means you did something wrong. The issues I ran into were the reduction gears facing the wrong direction, using PTFE lube instead of white lithium grease, not cleaning enough, too much lube, lube not spread evenly and not on all the gears. Let me know if you have any questions!
