@chargepositif I have an update on this. While I didn't connect the diode and check that, I did fire up the fiber and the tool layer does indeed frame. On the CO2 w/ a Ruida controller it does not, unless you use the "Rubber Band Frame" button - the one with the circle. Then it'll frame the tool layer. No idea why, I think it's a bug but Lightburn devs are aware of it.
