Over the past few days I've had a new issue with my machine. During a print with CPE and standard UM print core (AA 0.4), the y-axis print head shaft fell out during the print. (This happened when the print was about two inches off the bed).
I popped the shaft back in and did some basic diagnostics and everything seemed to be fine. I did some test prints and sat and watched and everything was good.
Later, I switched over to a 3d Solex printcore (so I could print nylonx) and did more test prints. Everything was good. So I let the machine go for another print job and went about my business.
Naturally, sometime during the print (about 1 cm off the bed) the same thing happened and the shaft popped out of the front and back brackets.
So I fixed it. Again. This time, I was going to watch the print and see what happened if it happened. Of course, the minute I take a bathroom break, it pops out again.
I have no idea what's going on. I've had the printer for three years and this is the first real issue I've had.
