Machine: 80W Goldmark 600mmx400mm wih M2 Nano originally
Problem/ Question: I have had my 80W laser for a couple of months but had been dealing with usb disconnect issues, so I wanted to try a new board. I had been using basically the default settings of the K40 Whisperer with the M2 Nano board with decent results when it worked. I was interested in trying the cohesion 3d board so as to try using the sd card without being tied to a laptop. I already had lightburn from using it with my 5.5W diode laser on my cnc.
I installed the laserboard yesterday. Comparing engraving samples from the M2 Nano/K40 Whisperer and the results I get from the Laserboard/Lightburn has left me a little underwhelmed. I assume it is because of something that I am not doing correctly either in lightburn or the configuration setting for the laserboard, so please bear with me.
It looks like the edges of a raster engraved image are pixelated on the lightburn/laserboard sample compared to the raster engraved image from the M2 Nano/k40 whisperer.
The lines per inch on lightburn are 254 compared to whisperer’s scan line step of 0.004 inches. I turned off the overscanning in the fill in lightburn and that seemed to help some. I assume there are some other things I need to adjust to improve my results, so I appreciate any help that anyone can give.
