I have been using both white and black PETG-HF and I get really good results with the black material. However, the white PETG-HF tends to warp off the Cool Plate SuperTack, strings and has zits all over the place. When I print with the black material the surface is smooth and clean and rather secured to the build plate.
Are there differences between the colors that need to be taken into account in the material profiles?
I’ve ran multiple calibrations on the white and I just can’t get as good of results as the black stuff.
This just sounds like the white is moist and needs to be dried

It’s bizarre to me that they list PETG as “recommended” for drying. Personally, I’d call it a requirement.

I’ve had both colors in dried for the same length of time. I have two dryers and set them to about 58C for over 24hrs.
Different colors require different ingredients, so different settings are often necessary for best results.
Strings and zits do seem to indicate the white needs more drying. You have no way of knowing how much moisture is in the spool, so there is no way to predict the amount of time needed to get it out. That is why I weigh my spools before I start and dry until the weight stops dropping.

This is a good idea. I pull the spool out and give this a whirl.
Thank you for the suggestion.
I had the white in dryer with a bunch desiccant and held it at the temp 58C. I weighed it before I put the spool in the dyer it was 1010g and after 24 hours I weighed it again and still 1010g. I’ve left it in the dryer and I’ll check again.
The black spool I’ve dried along with the white is still in my AMS and I’ve been using it non stop and no problems.
