We have 2 Mira 7 machines. When trying to engrave (scan) one machine works fine, the other it’s blurred. When we send the job from RDWorks it works just fine on both machines. All settings appear to be the same. Both machines are connected via ethernet (not wireless); both machines have the same ruida controller version.
Check the reverse interval settings in the RDWorks version that works. You likely haven’t set those in LightBurn (and, be aware that LightBurn uses half the values that RDWorks does - I think RDWorks automatically cuts the numbers in half, and we do not).
