I have had two print failures now with my K2Plus with CFS–which I was also having on my K1c with CFS. With the K1c, it told me it was memory issues or non-specific errors. With the K2 plus, I have gotten a fan error, and two BM2355 errors: “MCU task scheduling failed, possibly due to high load or communication issues.” and two 2s2353 System error, try restarting.
are there limits to the types of things you want printed? I was trying to print small refrigerator magnets (100 initially then still failed with 50). They only fill 1/4 of the K2 plus print bed.
The last time, it failed after a single layer print (5 colors). Pretty frustrating. I had hoped I left these types of problems behind with my K1c.
