Hey everyone,
First off, I would appreciate any and all help with this issue, as I'm quite at a loss at the moment.
So I'am running a heavily modified Twotrees Sapphire Pro corexy printer, and it produces quite fine prints, almost perfect.
The issue I'm facing is that I've recently purchased a spool of white TPU, and while printing ring objects, it produces these weird artifacts.
Please view the picture for details.
To me it seems like the lower half of the objects has shrunk, or that the layers has shifted, except the issue isn't uniform, turn the object 180 degrees, and that side is OK.
The circles are perfectly uniform.
I've tried tightening the belts, re calibrating everything (e/x/y steps etc). I'm printing at 205 degrees on the hotend, and 50 at the glassbed. The hotend doesn't go lower than 200 without affecting extrusion, and the bed I've tried at 30 degrees, but no difference. Speed is 7mm/s across the board, except travel. The cooling is running at 20%.
Any ideas?
