I will have to look at the designs to see what I can share, but I am sure there is something I can post. I’ve been trying different papers to get the right outcomes (we have a paper studio after all, so there’s a lot to choose from!) but for thicker papers I’ve been using a lot of 500 speed / 60 or 65 power, which blasts through quickly without a lot of residual scarring. maybe for finished pieces I’d slow it down and lower the power but for quick trials like these I want it done faster 
the fact I can’t save power settings as presets in GF is pretty maddening but I expect it to be resolved soon enough; I’m happy it saves all my settings from previous cutting sessions so that’s enough for me right now.
