Oh well – I have to apologize. I did a few more experiments, and found out where the secret hides. Yes, there is a small button on the CrealityPrint slicer to connect the printer. I could send a print file to the printer downstairs, only I could not start the print. I had to do that manually on the printer. But maybe I will find out also how that works.
At least it seems I don’t need Neil’s help, atm.
Kind regards,
Hans
