I am in contact with tormach for help with this, but I was wondering if any of you came across this before? All my threads look like barbed fittings. The start end thread form looks more or less correct, but the back side looks like a different degree. Using iscar lay down inserts, tried a shars one too. same results from conversational or fusion. It did this on earlier versions of path pilot when I got the machine, but I didn't need threading at the moment and assumed user error. My thought is maybe the timing is not calibrated correctly? I verified z travel to be accurate to a known good indicator over 1.5".
