Help configuring Marlin for different extruder
I have a homemade 3D printer setup and working with one exception. The extruder steps per unit does not seem to work ccorrectly. This particular extruder needs that to be set to 400, but no matter what I set it at, extruding 100 mm results in extruding about 150 mm of filament. I set it to 100 and it still extruded 150 mm.
I am using Arduino 1.8.9
Marlin 1.9 tweaked for Robo 3d
Here are the relevant settings.
Any thoughts on why the extruder setting may not be working when I was able to successfully change the Z setting to 400. .
