I just switched from GRBL to AWC708C on my homemade laser and am now having the scanning offset problem. It seems fixed with the Lightburn software option for the 100mm/s and 300mm/s but as shown in the images, the 200mm/s rectangle is skewed in both. Any ideas? Also, why would the laser not have this issue at all with GRBL (on 8 bit controller) and have the issue on a nicer controller, I believe the 708c is 32bit? Thanks for the help.
