I installed the K1 Series CFS Upgrade Kit and CFS recently and have noticed a real problem. Sometimes, things work fine. Then the Z axis will move down instead of up while homing. Unless I turn the machine off, it will move all the way to the bottom and then try to keep moving, which can’t be good for the mechanism or the belt.
The only way to get it back to normal is to turn the machine over, take off the bottom cover, and manually move the Z axis up to the level of the side-fan’s outlet. Then it will work properly for a bit before repeating the problem. The firmware was what was on the USB stick, which is 2.3.5.33. I really would like to know what is going on and, more importantly, how to fix this so that this problem does not happen again. Any viable solutions would be greatly appreciated.
