Prusament PETG on Texture PEI sheet issue.

Hello, 

I have trying to print Prusament PETG on the Texture PEI sheet. The first layer calibration was OK, but when I try to print something I obtain the results shown in the pictures.

My current Z is -0.850mm. If I decrease this value (Increase the distance nozzle-plate), the adhesion is very bad.

May anybody tell me how I can solve this issue?

Thank you

Adjust your Z like in this article and post a picture of your result.

No point printing anything else until your Z is correct.

Thank you,

I've recalibrated the printer. The Z calibration provide for the firmware is not so good for PETG. I have calibrated according this picture: 

As reference, these are my values:

Steel Sheet:
PLA: -0.520mm

TXT Sheet:
PLA: -0.850mm
PETG: -0.750mm

Another issue was the correct cleaning process.  I solved it with wiping with IPA the texture sheet with a towel paper pressing a lit bit to allow clean correctly the ultem micro cells.

Finally, I'm happily printing PETG.
