Yes I Did! Thank you.
See this thread: [DLC32 M4 does not work]
That was my problem… M4 would crash it. I flashed with the firmware that was given but didnt fix my problem. Trying to flash back the flash program could no longer sync with the board. Being short on patience I figured it’s time to give FluidNC a shot. That loaded easy enough and communicates fine with LightBurn. I’m running the board here on my desk with nothing connected, homing disabled, watching the lights flash as it cruises thru a job. I’ll get it hooked up to a ‘real machine’ tomorrow.
Hope you have better luck. I’m not disappointed with my board, I think it will do fine with FluidNC. Yet another adventure!
