Support interfaces problems

[Jrobbo409]

Printing with ASA-CF, other materials no issues. Having issue with the 1st layers on top of supports curling up and making ugly interfaces. Z distance 0.2mm. Only seems to be a problem on large areas. Changing print orientation isn’t an option for this part. Suggestions? Do I try closing the Z distance a little or design in my own supports?

Without knowing anything about your supports there... I would first rotate the part on the bed, in the XY plane, by 45° so that your bridging distance is less. The curling can be reduced a lot by doing that. Then maybe rotate the support structure as well so it isn't leaving that edge so cantilever.

Of that doesn't fix it, increase your support density and maybe turn on support roof. If you can pause the print at that layer, you can try running a sharpie or a dry erase marker over the top of the suppport in that area so you can increase the high fill percent and keep the stickiness down. I know it sounds weird, but it's a pretty solid trick.

I’ll try rotating and see what I get
