thanks for the reply, i am using the S5 printer,
so even the flexifil is a TPC it is ok to call it a CPE and chose this on the printer when feeding it is that correct?
Have you used the Colorfabb varioshore on the ultimake S5 as it is only a 92 TPU and not 95
Generic CPE works at similar temperatures. I would use this as a starting point. AA0.4 print core is the correct choice.
Make all speed settings visible in Cura and print slow (approx. 20mm/s) at approx. 250C (depending on the layer height).
It works better for me if i set the feeder tension a little bit higher than normal. And you can increase the flow setting in Cura to approx. 115%, if you still notice gaps between printed lines. Use little to no fan.
And as with all flexible filaments: it's not suitable for prints that require a lot of retractions. Try to reduce the count of retractions to a minimum or switch retractions off.
If the filament sensor doesn't work for this type of filament it should be possible to switch the sensor off (someone with an S-Line printer probably knows more).
I don't use the "material unload" function but simply pull out the filament by hand when the print is finished. Works like a charm... 🙂
BTW: which printer is it used on?
...oh, and if you print tires as functional parts... you should take a look at Colorfabb Varioshore
