So I went through the online instructions TWICE and I am running into the following…
When I print my “Keychain” sample after setup, it comes out fine.
When I go to print a new dual extrusion print, the rear hot end is touching the build plate and the front hot end is at proper height. This problem causes the filament in the rear hot end to jam against the plate and the gear grinds into the filament.
No matter how many times I raise and lower the front hot end, the same problem occurs.
When I send it “Home”, the rear end barely touches the edge of the home button, and not the center of it. Then, when the heads clean against the cleaning pad, they move around considerably and do not appear to be centered on it.
Can someone give me some guidance on these issues?
