Steppers and stepper boards are cool
i tried lowering the temperature with no success i had under heating problems
retractions have been reduced to hotend manufacture suggestions
part cooling fan was at 30% to 40%
i tried everything i could think.
I found others with similar problems with that specific hotend.
Probably mosquito is more focused in printing with high temperature materials and i

The build is new in a lot of areas.
New motherboard
New stepper drivers
New stepper motors on XY
and after all that a new hotend
The problem appeared when i changed the hotend.
I am more confident that the problem is some kind of heat creep as i again finished another 2 hours print by leaving the enclosure open and have an ambient temperature of 20c.
Today i will revert back to the e3d V6.

Material : PETG
Hot End : Mosquito Magnum (as stated in the first post)
Temperatures : Black PETG : 255c Orange PETG : 260
Speeds : Not remember exactly but nothing fancy considering i am using rather moderate speeds due to material (PETG) . Not sure but its like 80 for infill/travel and 40 for perimeters
Cooling Fan : 30%-40% after layer 3
BUT please keep in mind that with same settings Bench

Come on any ideas ???
Is this hotend heat creep
or
z axis skipping problem.
Z axis never had any problems and as you can see it manifests in either higher or lower layers.
I tried to print with the enclosure open keeping the ambient temperature at around 22c..25c and i managed to finish printing a two hours print.
So i am thinking the heat creep is more probable cause.The mosquito has an 25x2

Hello all,
this happens after one .. one and a half hour of printing.
Benchy and 20x20 cube are printing fine with dimensional accuracy.
It starts as underextrusion in infill and finally the nozzle starts dragging and the print fails.
Printer is in an enclosure so ambient temperature is around 30c .
Every time i check for overheated stepper or stepper drivers but both are relative cool.
