Dear Greg, I hope you don't mind me trying to get in touch with you via this forum about your former project, the Microslice? (If it makes it any better I'm on my second E3D v6 on my MakiBox 3D printer!) I have had a 2.6 kit lying around unbuilt, as it was a bit beyond my knowledge when bought for me as a present some years ago, but have recently tried to tackle it. I have the instructions for the 2.5 model, which I've been following successfully, but can't find the instructions for 2.6 (the link I had is now broken) and I think there are some differences (no raster/vector switch maybe?). I'm also lacking the correct firmware; it seems that the one I need is the LaserMode branch here: https://github.com/alsliahona/grbl/tree/LaserMode but I'm not sure? Any help with the 2.6 instructions/build manual and/or firmware would be really appreciated. Thanks, Jim.
