prusa i3 extruder issue
November 21, 2015 05:52PM
Hello, I have an issue with my printer extruder. I set to extrude 10mm of filament but it actually extrudes ~ 5mm, when E steps in marlin set to 7000 and I think motor spins way too fast . In this video [www.youtube.com] E steps set to ~928 but motor sipins much slower than mine. What is wrong with my settings?

Try 1000.

Your motor gear might be slipping on the filament and not grabbing it.

Check your micro-step jumpers. You may have one loose.
