MakerFarm Pegasus 8' Printer Problem

[DreaMPoweR]

Thanks for your reply.

Well, I built the printer in a workshop so before doing anything, we checked everything but after that have not done any calibration. I am new to 3D printing so do not know how to calibrate.

Yes, it prints as you described. I also attached new pictures and apparently, the problem is only the front part (towards to front). It seems that when it finishes a layer and comes back to start a new layer, it kind of pushes a little more filament. Yes, this might be still an issue about retraction.

I have not had any issues with the printer bed but I will keep an eye on it.

Retraction:
Length: 2.5mm
Lift Z: 0
Speed: 40 mm/s
Extra Length on restart: 0
Min. travel after retraction: 3 mm
Retract on later change: checked
Wipe while retracriong: unchecked
