Two little MK4 bugs  

Two little MK4 bugs

I love my new MK4.  It and my MK3 sit side-by-side in the hood.  The MK4 is MUCH quieter, ~25% faster and can handle all the way down to 0.05mm, where my MK3 choked on 0.1mm.  I uploaded the 4.7.0, which requires complete re-setting up the machine including WIFI, PrusaLink and running the calibration set.  All runs so well.  

But there are two little problems:

1)  After several (did not count, but ~10) prints with color changes, it does not see the removal of the 1st color, so cannot move forward with the print.

2)  Again, after a bunch of printing, the start-up "dance" includes checking the X-axis calibration comes back saying the X-axis cannot be calibrated (don't remember the actual words) and it stops.  

Both problems are resolved by hitting the "Reset" button (turns the MK4 off then on again).  Now, that is my habit every so often and the problem has not resurfaced, but it sure would if i just left the machine on.  

Overall, this upgrade its worth every single penny I spent on it.  Small, precise parts come out looking like they were injection molded!
