PETG way off  

RE: PETG way off

Ive found that pla and petg often require different zoffets.  I set up separate steel sheet profiles for pla and petg.  Tpu even has a different z.  Create a 75 or 100mm .2mm high test square and calibrate each sheet profile separately.  Petg is usually less negative I.e further from the plate

Agree.  We need a first player calibration print to help.

No joy. What you see is a range of Z offsets. Even when I got one fairly close, it still had this pulsing effect throughout.

Petg needs to be higher generally than pla on the same plate.  The textured plate definitely likes petg as long as it’s clean

your waaay to high, lower the nozzle

RE: PETG way off

Sorry if I wasn't clear earlier, but this is just the worst of it - at the Z level suggested by others. It seems like no Z level will work. What seems to happen is those lines of excess material across the direction of the print. Look at the right side. See how very little material is laid down, then splat! a big blob as the direction reverses, then back to almost nothing. Then a hiccup of material, then too thin, etc. etc.

Are you sure you've selected a suitable PETG profile in slicer?  Looks like the temperature could be too low given the poor extrusion, I'd double check the recommended settings of the filament.

I agree.  if you zip up your .3mf file and attach it here we'll be able to see what temps you are trying to print with.

In my limited petg experience I found that when the z is too high the filament has nowhere to go but back onto the nozzle. This results in the excess finally depositing on the print or worse catching the print and lifting it.
