It's too late to help the OP, but I thought I'd write this to help someone else down the line. We had the same problem with the T22 error. Here's what the folks at Cubify told us:

Thank you for contacting Cubify!

A temperature error can be fixed rather simply.

Please uninstall the print tips and then reinsert them.

Make sure you turn the tips until you feel a slight click and that the dots align on the top of the tip and carriage.

If this does not resolve the issue then please unplug the printer form the outlet, uninstall the cartridges and wait about 5-10 minutes.

Insert the cartridges and then power the printer back on.

This should resolve the issue.
