Printer: MK 3.0
Firstly, apologies, i bought my printer fully assembled, a thing i now regret because i have no idea how to fix what is now happening - i hope you guys can help!
The printer was working fine until i couldn’t unload a filament that would not come out - i had to open the extruder and pull it out - the end was a bit fat. anyway, i put it back together and the next few prints seemed fine
Then i started printing my first several hour print - and i had to stop it mid print because it looked a bit messed up - lots of spots on it: https://imgur.com/uCzLfYZ
this is the first print i ever made from the printer after it was delivered: https://imgur.com/ChKT4jS
I printed this after the failed print i mentioned above: https://imgur.com/iZruPrx
I ran the wizard in the calibration menu, and then printed this: https://imgur.com/7PTwOXf
Not sure what is happening, but feels bad man
any help much appreciated!
