My problem is with the Glowforge interface.
As I’m in France, I can’t buy proofgrade material (shipping is too much expensive). So I use only non proofgrade material. The Glowforge interface allow to save presets. So for each material, I saved presets (like for 3mm MDF, I use 160 speed and 100 power with only 1 cut).
This morning, all the presets are missing. They have dissappear. I tried to save new ones (as I get the parameters written in a notebook), but it doesn’t work. It’s a pity because using this kind of presets make me gain a lot of time.
