They really are.

The MK3 is an absolute beast of a workhorse. We use two MK3s at the lab I work at. They collectively have 2000 hours of print time and they just now started exhibiting issues. One had a hotend fail, the other had a thermistor fail.

They’re damn good printers. I heard bad things about the MMU2, but I’m hopeful the MMU3 will be great, I have one on preorder.

I’d look into the nextruder upgrade for you MK3, it’s really nice. Only two thumbscrews to release the hot end out.
