UM2+, USB does not work with my MacMini M1

Why can I not print via USB-Cable with my MacMini M1? I use Cura 4.12.1

 

Printing via USB-Cable with my old MacBookPro and Cura 4.8.0 works fine.

It could be that a driver is necessary. But since Ultimaker never officially supported USB printing with the Ultimaker 2(+), if Apple is not providing that driver for their new architecture then chances that you will get this to work might be slim.

 

You could try if you can save the gcode to a file and then print it using Printrun (www.pronterface.com). Or if you want something that is nicely integrated into Cura, you could install OctoPrint (either on your Mac Mini, or on a Raspberry Pi), and print to that with the OctoPrint Connection plugin available from the Marketplace.

I see from time to time also problems with other USB devices on my Macs when using a USB-C to A adapter. So maybe try another adapter if you have one. But the driver issue can still be a reason as well, as ahoeben mentioned above.

It would actually be useful to know if Printrun works on your M1. If so, I might dust off my effort to integrate the core of Printrun into a plugin for Cura, replacing the existing non-maintained USB Printing functionality.

Printrun was also not working on a Mac before M1, so save your time 🙂

I'ld rather have an answer from someone if *any* application successfully does USB printing. Printrun not working does not necessarily mean the core of printrun is at fault.
