I just verified my E-Steps: 98 mm @ 1.5 mm/s (100 mm were requested)
I successfully printed yours and the following models in the past:
Then I noticed I was under-extruding all the time (88 %, which made my PETG prints fail). When I fixed that, the printed hinges started to get fused together. I have to reduce the flow rate to 90 % to get working hinges again.
Thank you for sharing the information - I'll try to find out what's wrong. Maybe the problem lies elsewhere.
