TronXY X5SA PRO with CURA 4.8.0 stops printing after a minute and freezes

[Petronius 0]

My Printer is a TronXY X5SA PRO with the 330x330x400mm volume.

The TronXY-slicer (which is said to be an offshoot of CURA) has no option for online print via USB - at least I could not find it.

And using these small micro SD-Cards does function but is a real pain.

Therefore my next step was to get the latest Cura version 4.8.0 in the hope to get the USB connectivity I had on my trusty old Dremel printer.

Well, I found the profile for my printer, set the Baud rate to the appropriate 115200 and could connect PC and printer.

Only to realize that there is some problem - after a minute or two the print stops without giving any information whatever the cause may be.

Temperatures of bed and nozzle are as I had set - hot filament slowly oozes out of the nozzle, but the printer does nothing, reacts to no input and has to be restarted.

All with the effect that I now have two holes burned into the bed surface.

Any help will be greatly appreciated
