PetG White layer bonding problem

[TomR]

I am having trouble with ESun PetG White layer bonding. No problems with black, ruby or Natural. The calibration is spot on: Filament diameter 1.73, multiplier 0.85 Width 0.40 with a measured thickness of 0.40. When printing the edge layers separate. I increased the multiplier and width to .90 and .42 to see if this solved the problem if underextruding. The measured thickness was 0.45. No change. I do notice the white petG filament is rougher that the other petG filaments. The bottom layer seems to be fine, just the edge layers split. Any ideas?

Couple of things.

I assume you are using the .35mm nozzle.

1) Print with no fan. When I used a fan while printing PETG I had bond issues myself
2) Increase your infil extrusion width % - I run at anywhere between 110 and 140
3) Print slowly - generally I print at around 65mm/s
4) Less retraction that PLA

Try those first. Once you dial it in it prints amazingly

I do have the .35 nozzle and print at 3600mm/ min. My infill is at 150. My black, natural and ruby petG all print great with these settings. Just the white is giving me problems. I love the petG and would love to get the white print like the other ESun PetG does.

Also I have the fan off, bed temp is 90 and extruder is 250

Try increasing infill overlap percentage.

Forgot to mention I run my petg white at 265... Granted that's with a e3d... Every other color I run at 250

I was wondering if the temp needed to be higher. What temp for the white petG is everyone using and how high can I safety go with the stock VB3.
