I find that I spend too much time ensuring that I get every speck of support material off the print plate long after I’ve removed the actual print.
When it comes to the skirt, I always set it to be two layers tall for this exact reason, and I was hoping it’s possible to do the same with the support base.
EDIT: PETG on textured printsheet



Yeah, that makes sense for your frustration. I get stabbed under my fingernails trying to take PETG remnants off the textured beds. I typically just deal with it because the solutions I’ve found are more time-consuming, but I guess it might depend on how much.
I’ve had people suggest heating the bed as high as it will go. PETG’s glass transition temperature is usually less than 90° C. I’ve seen some people print over bits to try to merge them to make them pull up easier, but that just seems like a waste of material to me. I generally don’t care for solutions that involve applying liquids or gels to the bed.
