Anyone using Lightburn for photos on there K40. I was doing good with Inkscape and k40whisper. But now that I switched to the C3D board and lightburn I cant get the knack of it. Trying do do a white tile painted black and it’s kicking my butt 
Thanks
You will get more responses if you could provide some information along with this post. Maybe start with what settings you have tried and what results you got. Show the starting photo, explain the changes/prep-work done to the photo if any, and the settings for each result you share. This will give folks a better chance to share their relevant experience which might benefit you in dialing in your setup.
