@Zax New version released with support for Cohesion 3D (CO2 laser) and Marlin firmware (3D printer + laser module) which uses M106/107 fan speed for laser power control. DXF Optimizer now works for the trace hatch. Lots more features and more coming soon. T2Laser is fully supported and stable but still actively being developed.
For adjusting photos for engraving, I am still learning from @nottingham82
He has a youtube channel showing many how-to videos Youtube Video
A rotary axis replaces your X or Y axis and allows you to laser on cylindrical objects. I have done wine glasses, wine bottles and wooden dowels. I know nottingham82 has engraved on some metal tumblers as well.
Here is my rotary axis https://www.thingiverse.com/thing:2565273
Thanx Zax and Nottingham82.. firmware was not required as eleksdraw is responding perfectly to commands. I finally managed to get a greyscale using velocity mode with 40 laser value and feed rate of 200 to 2000.. will do some more tweaking to get more good results .. thanks all for your help
So the nano is the little controller board that the USB plugs into. If you pull it off the board there is 3 pins and a little connector called a jumper. Move the jumper from the middle left to the middle and right pins. It should be marked .9 This will let you run the new firmware.
