Help improve my print quality
I got my printer (mk3) built a few weeks back and I’ve been printing lots of stuff :).
I am a little disheartened by the way some objects come out. Can someone suggest what’s wrong? I believe I’ve got my belts tight enough. But the print maybe has layer shift?
Re: Help improve my print quality
Do you have these artifacts both in X and Y direction?
For a start you can check if the grub screws against the drive shaft on the idlers are tight. Looseness of those might lead to what looks like tiny layer shifts.

Looks like the root cause is uneven extrusion. Here are my thoughts on it:
1. Check extruder gears are perfectly aligned and sits tight
2. Change filament.
3. Make some cold pulls to clean up the nozzle

I don't think it's the the grub screws those seem fine (I checked them recently with the belt tension). it could be uneven extrusion though, the gears look fine, and I believe I've got the right tension on the extrusion gears (though it isn't clear to me how to check) I very likely could need to do some cold pulls I've had clogs in the past....

Did a few cold pulls and printed it again. The results are much better!!!
Is anything wrong with this (seems near perfect to me)? Anything else I should do?
Thanks so much!

Glad it did work out. Without knowing how you sliced it, maybe reduce the extrusion multiplier and slow down the print. It might produce better quality.
But with a pure white filament I would consider this as a really good print already.
