Can't change material on touchscreen


I’ve raised a support ticket, but thought I’d post here as well to see if anybody can help. My printer is loaded with PLA and my file is set to print PLA, but I can’t change the material setting on the touchscreen. When I press the ABS button on the touchscreen it doesn’t change.

There are 2 identical machines in my classroom - one works perfectly but the other has this fault.

Can anybody help?

You may need to connect the machine to computer and change the material in UP Studio for once.

Did you ever get this resolved? I’m having the same issue. Thanks!
