General Mach Discussion / Re: Turn + Threading problems

Hello. I have a question about disk to recognize velocity and position of spindle. At older versions of mach I could use disk with some slots and one wider. Now i had to change PC in my turning machine and install the newest mach,but It works with one slot only! I dot like it. From time to time I have to cut thread on quit big pipes (~10"), then speed of spindle is rather low (~50 RPM). In spite of high power of spindle motor - 10HP, the rpm is not so rigid and plays according size of chips. At low spindle speed, it makes problems, thread is imprecision. So do you have any ideas to solve this problem?

Regards Marek.
