I have successfully printed a few models on my Maker Select V2 (Wanhao Duplicator i3) including 3D Benchy, but I'm seeing a consistent problem with a model that I've sliced with Cura.
The extruder starts by doing a little filament wipe at the origin, then moves to the center of the build plate where the part should be printed. During this move, it extrudes a big burst of filament (PLA), several centimeters worth, which completely ruins the print.
I debugged the initial G-code that Cura uses, and am able to reproduce the problem with this:
M104 S200 ; heat to 200 C M109 S200 ; wait to reach temperature G21 ; metric values G90 ; absolute positioning M82 ; set extruder to absolute mode ; move to home G28 X0 Y0 G28 Z0 G1 Z15.0 F120 ; move up 15 mm G92 E0 ; zero the extruded length ; problematic! G1 F200 E6 ; extrude 6 mm of filament
What this is doing is moving to the origin position and pushing some filament through the extruder.
