This is my second print using TPU, after the calibration cube. The material is soft. The main strategy is to abandon all hope of retracting the elastic filament. Instead, to maintain a constant feedrate so the pressure in the hotend can stabilize, cross perimeters as little as possible, and do rapids as fast as possible.
Is this with a bowden extruder or direct drive? Getting a MicroSwiss made TPU95 print as easily as anything else for me. I also have a sample of Cheetah, which is super super soft, but I haven't had a chance to try it out yet.
