Indded I didn't and I try to use the more decimal numbers the calculator allows me to use. Fortunately I only have 1 gear on the Mazak, but anyway the encoder is directly coupled to the spindle shaft with a timing belt so no issues with that matter. Its working flawlessly now that it has the original control so it should do equally right with LCNC. The beauty of having a continuous curve for lobes drawn in autocad is that I can export them with the amount of points I want so I can match the encoder exactly. Now I'm doing fine with 512 control points, but If I want I could use the 1024 pulses of the encoder each one with a control point. The only thing I have left to test is how it goes on the Mazak at around 200 RPM which is the average speed I plan to use to turn the lobes. I hope I can go back as soon as possible to install the new control and start the real machining :).
