Stringing and jamming with Cheetah TPU configuration file #6

Open arkorobotics opened 4 years ago

The default Cheetah-TPU.ini configuration file results in stringing and jamming when loaded for the Prusa Mk3s w/ Cheetah TPU.

I was able to get clean and consistent results after applying the following changes: 1) Disabled retraction 2) Slowed all speed variables to 20mm/s 3) Increased the extruder temp to 240C

To those unfamiliar with flex material (like I was before trying to print this), I recommend applying a glue stick to the work area prior to printing. Otherwise removing the print will likely result in warping or tearing.

Here's a photo of the comfort print after making the changes mentioned above. IMG_1620
