Got around to printing some dry boxes for filament to hang off the back of the printer. Been holding a lot of workshops for 3D printing at work and doing a roadshow with our prototyping program, so it's got to be put up a notch in the professionalism department :-)
So until that gets sorted out I'm back to using the CTC for a while. Really missing that auto calibration right now!
EDIT: Contacted Duet3D for a warranty claim and they got back to me within half an hour. I get to return the faulty controller and they are sending out a replacement ASAP so I can get back to printing, great customer service!
