I am starting to have some major issues with my machine . I am working with the rotary jig with 3 inch pvc pipe as show in the carvewright site. I load the project the machine homes itself then it measures the distance , it ask to load the carving bit , I do and close the door and hit enter , usally the cut motor would rotate with the bit , now it wont , it just goes to the keyboard side like it is going to check for thickness. The bit does not go all the way down to the fixture , it tries two to three times then snaps had to the keyboard side of the machine and gives me the error code. I tried to video it but it is too big to attach to a email or text from my phone . I have changed the ribbon for the z truck , I also replaced the termination board. It figures I would have this when carvewright is closed. If anyone has the LHR troubleshooting guide for the errors codes or knows what causes this could you please let me know. My email is woody315@centurytel.net . I am in desperate state here. Please help !
