My touch screen seems to have a problem. When you switch it on it seems to respond, but shortly after that it stops reacting to tough. I had to use the idea maker software to connect and control it. I have had to take apart the second extruder to clean it and been trying to reassemble it and calibrate the hot end s. Seem to be having trouble setting it right. How big is the gap supposed to be between bed and nosels as tries a business car but it kept getting pined or scratched and when I tried to print it appeared to be rubbing the build tac and blocking the flow causing gear skip, but when not on the surface material does flow. it also seems to want to calibrate over the edge of the build plate.
Any help will be apprecited.
I didn't find the right solution from the Internet.
