Start printing issue
I have built my printer, everything works fine, I used the firmware configured with the utility online.
Now the problem:
when I start printing in ABS, the bed warms up, then warms the head. When the head reaches around 160 degrees, the extruder (case A) retract rapidly about 40mm filament, then the head continues to heat. So before you start printing the extruder expels (case very quickly about 50 mm of filament.
In my configuration using an extruder type MK7/MK8.
This is my problem:
The (case A) brings out the filament from the drive gear and the (case can not take place because the filament is out of the drive gear.
I tried a parameter to adjust both the (case A) and the (case but I could not find anything.
Can you help?
