0.6 nozzle, 0.3 layer height and 0.6 line width
Seems very hot for TPU
@elcoj you think it would help if I increase the extrusion multiplier ?
I think less than 0.3 later height will help a lot more
Try 0.2
And TPU probably needs a lower temperature. What does the spool say?
ok will try 0.2 and 245
nothing but ill try 245

I've set my extrusion factor to 1.2, 210°C first layer, 205°C next layers, 30°C bed, 0mm retraction, and my Sunlu TPU prints quite alright on an otherwise stock RR TPU profile from PS
ok will try that. do i need the cooling fan ?

Won't do harm I'd say
its so weird on my ender 3 the same tpu printed perfect but on the ratrig its doesnt print good at all. sadly i dont have the old slicer settings anymore
