need some help with a problem I got.
First: the magnetic balls that hold the bars, which in turn hold the printer's head are dirty from some black stuff which I think comes from the bars themselves.
I tried to clean them but it does not help much and I think it cause the bars to disconnect during printing of large objects.
Second: as mentioned above I have difficulty when printing large objects, I tried to print the back cover of an electric motor that I designed: internal diameter is 6.5 cm and outer diameter is around the 12 cm, around 25% completion of the printing the head disconnected and I had to abort the printing.
Third: when printing with PETG the plastic keep piling up on the head, later on big burned chuncks fall back.
I tried to recallibrate and made sure there is enough space between the nozzle and the bed but it dosen't help..
Also with PETG the first layer look hideous most of the time..

First:
For me...
After each month, I always clean those two ends and lubricate with machine oil. Never like grease as it will collect dirt easily.
Second:
You may need to check the belts. I hope that helped.
Third:
PETG, Measure diameter of the filament first. And change in settings. Then, you may need to adjust retraction and speed flow.
Give a bit more speed, you have 40-50mm speed to play.
And make sure to clean your nozzle. Heat it, and wipe it of with acetone.

What kind of acetone? should the head still be hot during cleanup?
Lubricate the balls themselves?

Home Depot hardware store acetone I use, and not acetone that use for finger nails, their not strong enough. And yes, make sure the head is hot when cleaning.
