TAZ 6 Archim2 CURA LE 3.6

Hi all

I have converted my TAZ 6 to the Archim2 controller and I was wondering if anybody has an ide how to “enable” the USB-print from CURA LE 3.6 again?
I can connect to the TAZ and run commands through the console.
When I try to USB-print 2 messages pop up:
first “Wrong printer detected…” → developer setting show suppress this?
USB-print message1
second “The printer has restarted or lost power”
USB-print message2

Has anybody any tips how to fix this or a recommendation for an alternative slicer?
