Do the axis GT2 grub screws commonly fall out?
Hey folks.
So I've noticed a nasty layer shift on the last few prints I've done and started investigating. Belt tension seems fine, took a peak at the grub screws to see if they were tight ... and noticed one was missing. Of course, it was there when I got it ;). I've had to do some tweaks here and there since I got it, and I know I've had to make minor tweaks to the pulleys and loosened then tightened the grub screws, but this is the first time I've noticed it's just gone.
Where ever it went it's certainly long gone. I've ordered some cheap ANET GT2-16 teeth timing pulley 5mm's off Amazon just to steal a single grub screw from it, but honestly I have no idea if they'll fit. I imagine they will but until they show up can't be certain.
Anyways, besides that, this is the first time I've ever seen a screw just go missing like that. I can see them jiggling themselves loose over time but I can't see how one can fall out completely while the others are all tight. Anyone ever heard of that before? Any one know the exact size of the grub screws so I can hunt some down in case these ANET ones don't fit?

Dual screws - if set properly - almost never fail. It's like using two nuts on a bolt to lock things in place. Set the screw on the flat first, then the screw on the round.

Grub screws are m3 3mm diameter 3mm length should do for the gt2 pulleys 2mm long for the bondtech
2mm long would probably so for both but they are fiddly
Dont use a ball end allen key on grub screws. You risk damaging the hex socket

check the magnets under your heat bed they love to catch things like grub screws and use a dab of blue locktite (NOT RED) when you attach them quality hex keys are a must when working with these as a slightly worn key will (like a ball ended key) increase the chance if stripping the internal hex socket. don't crank on these when doing them up just tight with blue locktite is fine.
