I have indeed a UM2

What do suggest to print PETG on the UM2?

[ERO3 when printing PETG]

Hi, I want to print PETG on my UM2, settings 70 on the heatbed and 245 on the nozzle.

Want to start the fan after the first layer on 100%

After some time (I guess 30minutes) the printer stop with this error messages on the display

I think it's because the nozzle is cooling down to fast, but I am not sure.

Anybody who can help me out here?

[bad first layer at right upper side with UM2]

hi,I try to print a large object and I find out that the first layer is very thin at the right upper side ...

how can I solve this? I already calibrated the nozzle!

[help with printing issue]

Hi, I have issues with printing the ribs, it prints fine for the two thirds of the print .

My guess because the object is moving at that moment and is unstable.

So second try I add support but you see, it's still bad :-(

can you please help me out here? I used for both prints a raft.
