Not sure where I can see it on Repetier. Is it the bar called feedrate in the Manual Control tab? That’s at 100 as well.
I can’t find those cubes anymore (I printed 2, just to make sure the first wasn’t a mistake). I threw them away. Both of them had a big lump protruding out of the Y face, and the other surfaces were all bumpy and lacking detail as well.
Accelerations are way higher than 200, but the extruder is not skipping steps or making any beeping noises.
I took the value down from 5000 to 200 for the test. Exactly 100mm of filament came out.
