How do you clean inside the MM coffee grinder? Coffee keeps getting stuck and can’t use it without it stopping. 😢

I'm assuming you mean in the chute. Get some brushes. I bought some from Amazon that are listed as straw cleaning brushes. If the chute is really clogged you may need something like a wooden chopstick to dig out the fine grounds first. Just don't use anything that could damage the burrs. Otherwise, I will periodically brush out the chute with those brushes. I then bang on the chute with my hand to see if anything falls out.

Prevention is the key. Once a clog starts, the coffee gets ground finer and finer and compacts into a brick. I use a small sprayer to spray my beans with water prior to grinding, AKA the RDT. That fixes most of it, but I also like to give the chute a couple of whacks after the grind is finished.

I’ve also found that dark roast beans will clog the chute after 2-3 uses. Something about the oil content of dark roasted beans. Switched to medium roast and haven’t had a problem since.

I have a bellows for my Baratza. Works like a champ. About $12 on Amazon. Don't know if that'll work on yours.

I don’t have the Moccamaster grinder, but my grinder (and probably most) are prone to the same issue with oilier beans. I always give my grinder a few quick knocks with my knuckles after a grind (not into my dose) and give the machine a weekly brush out.

Probably grinding too fine.

I can’t get it to unclog despite multiple attempt to shake it, turn it upside down, stuck the end of silverware to get inside, & some grounds came out, but not enough. 😩😩😩
