Same for me when using production firmware, it’s great. But when using the beta firmware whatever I do it fails. And the customer support says that they could not replicate my issues… I highly doubt that.

See my post here
So I rolled back to the latest public release and re-ran all the calibrations. The left nozzle layed down a clean first layer but now the right nozzle is having issues with symptoms of over extrusion (rippling). I just can’t catch a break 
. I’m going to run a high precision nozzle offset calibration tomorrow, and then try printing with the nozzles seperately and then in the same print to see what happens.
so you were on beta and you had issues, now you’re back and the issues are roughly gone?
Tl;dr the primary issue was that the nozzle offset calibration wasn’t working at all and would error out if I tried to run a nozzle offset calibration. This issue was happening on both public and beta releases. Replacing the nozzle offset calibration sensor with a new one fixed that issue. Now the first layer is wavy on my right nozzle when I never had this issue previously, but my left nozzle layed down the best first layer I’ve ever seen from it.
try do a full calibration and check if the nozzle seat (the seat that holds the hotend) is loose, and probably check the screws as well
