I would first try a thorough clean of the print sheet as your problem is worst where some users habitually leave fingerprints.

If that doesn't work run a first layer 'Z' calibration and show us the result *on the print sheet.*

Cheerio,

We have a complication in that you are printing PETG on the smooth sheet which requires a layer of release agent.  If possible switch to PLA for this procedure and we'll switch back later when it's under control.

Clean the print sheet with dishwashing detergent (Dawn/Fairy) and plenty of HOT water.  Load PLA (you risk PETG stickng too tight) and run a first layer 'Z' calibration.  I suspect your Z level needs to be lower, more squish.  When you have neat, sharp corners on the zigzag and the postage stamp at the end is a smooth sheet that does not break when you bend it come back with a picture of the result and we will look into whether the bed is evenly level.

Cherio,

  • I think your first layer calibration is still not good. Only when you get a good calibration you can expect your print to go well. Move the nozzle slowly further down to the plate until your lines stick to the plate. Careful not to go too far down and damage the plate, though. Always make sure your plate is clean and thatbyour temperature settings are correct (matching your material).

good luck!

Your print sheet looks terrible - how much of that is scratching and how much can you clean off?  Do you have another, clean, sheet or side?

The filament you are using is wet.  Dry it before trying again.  You need to go a little lower with your Z calibration.

Cheerio,
