I am not sure how this slipped through, please accept our apologies in this delayed response.
What version of LightBurn are you using? We have had a few communication issues with the last few releases (9.21 +) affecting Ruida and Mac, but primarily Big Sur. All reports so far, identify 9.24 resolves these communication issues. Have you tried 9.24?
There have been a couple issues reported with Ruida 320A compatibility in the most recent . All of my hardware is packed for our upcoming move, but I’ll be looking into this soon. In the meantime, can you try going back to 0.9.20 and letting me know if that works properly for you?
Unfortunately, nothing to further report at this time. We are working on this, but some delays have occurred. The recent corporate move required pulling the plug and putting a ton of gear in boxes (computers, cables and controllers, oh my), which we are unpacking and setting up in the new digs as we speak. This has impacted our development efforts, but things are getting sorted, we are settling in and getting back to our normal routine.
I’m having the same issue with my Big Sur M1 MacBook Pro using a Ruida RDLC220 (Voccell). It doesn’t frame correctly which makes precision placement very difficult. My PC runs fine, but is no longer adjacent to the laser.
