Topic: Problems with circles

Seems my prints are ok except the worst part being circles and curves. Suggestions, I've tried to calibrate what I can.

Re: Problems with circles

Do you have a fan on your printer?  If not it would help a lot with the small features/layer being printed to fast. Also, under the filament settings, change your cooling print speed to 20mm/s or so

As far as actual calibration, this tutorial should help you out quite a bit:

+1 I would add that circle problems are mostly caused by misalignment of the side Y-axis belts.  Second to that is deflection of the y-axis drive rod.  This can be fixed by adding a pillow block with bearings on that drive rod.  Search " how to end circle problems forever"

Re: Problems with circles

There is the stock fan on my printer (SD2), it seems to be going at all times.

I have no adjusted my cooling print speed, so I can try that.

I'll check out the "how to end circle problems forever" about those Y belts. I also have not tightened the various belts in a long time, and I have been printing a lot.

Thanks for the help.
