I’m pretty new to this, so maybe this is obvious to most or all of you, but wanted to share my experience anyway!
I printed off a couple models and was having an issue with the support material sticking to the print rather tightly. The top layers of support were essentially fused to the print.
I will switch between normal and tree support to view the slice, and after some trial and error I realized what was happening.
If you choose tree support and take the “experimental” values from the pop-up dialogue, it sets “Top Z Distance” to 0. When you switch back to normal, it does not automatically readjust this value - you will need to manually set Top Z Distance again. If you do not change this value from 0, your supports will be fused to the part.
Just throwing this out there for anyone that ran into the same problem!
