Hi All, I have a CR-10S PRO V2 that I bought second hand. It has an intermittent problem that i need your help with. Generally it prints fine with far better quality than my anycubic I3 mega, but, yesterday I printed a file successfully twice one after the other. I then set it running for a third print of the same file straight after clearing the previous print. I checked after 30 minutes to find a birds nest on the build plate, the head was printing about 150mm above the build plate.
I checked and releveled manually and then auto. I started a print, as the auto level process did its thing, it got to point 7 and the touch sensor did not deploy and the Z axis went up not down. I switched off and went through the whole leveling process again this time when set to print the auto leveling process went fine but the print failed, I think the Z was too high and the first layer failed to stick in places. My machine is running firmware Ver 1.70.0 BL. Standard machine. PLA at 200 nozzle temp and 60 bed temp
Your help would be much appreciated thanks
