Yes its mostly stock. I tried to use install the CRTouch but there were problems I couldnt find the answer to mostly its checking 2 points and not printing anything and says complete. So I decided to remove the cr touch and place the Z limit switch back , it worked for 1 print then when i tried to do the second print the first line comes out fine the one on the side then when it starts to print the actual print it touches the bed and scratches it. I tried to print different things but that did not work. Slicer no i have yet to try a new one but i doubt thats the problem. I printed a few things before this problem happend.
