What could this be?(V Minion)
I printed this petg at 245° with an 84° bed. My bed and hotend are both pid tuned. This spool has been kept in a bag after it was used each time. I pid tuned both hotend and bed, set the appropriate rotation distance, swapped to a new nozzle, and I am using vz hextrudort. My bed's deviation was 0.204mm. Could this be bowing on the vminions x gantry(I noticed the ratos mesh deviation slowly kept reaching to 0.5mm), could this be z wobble or is something else off?

A deviation of 0.5 would definitely call for a re-adjustment - with such a small part, i doubt that's the core of the issue in THIS print tho.
PETG is a moisture bitch tho. Even in Bags etc. it IS sucking that up, so before you try anything else, try drying the hell out of that stuff, if you have to, in the oven 😅
THEN try other stuff 👍
Thanks
I think I figured out the issue partially, the motor I received had a bent gear and had more resistance to move in one spot by hand.

Nice find!

second that - there must've been some serious shit going on to bend a stepper shaft 😅
It was actually a new stepper😵💫

oh - i wasn't implying it was you. my first thought was "shipping company" but then again, they are usually neatly packed. who knows what went wrong there ^^
Now that you say it: You did not overload the shaft way too much by belt tension or something, didn't you? 😅
Not at all, I just was trying to use it on the extruder, but then I later compared it to the popular pancake ldo motor people use and something felt off.
In fact when I first saw the motor like that I thought this was just how moons had their motors, but I ordered a spare and that one did not have it.

it's good that you found it. problems like that can drive you crazy

Well, shit ^^

It is worse now with the fixed motor?
Nope the final picture I sent is the result with the temporary ldo motor, ignore the layer shift I was outside when that happened.
