Hello. I am having an issue trying to make some threads on my lathe. The lathe will make a correct pass with the correct pitch on the first pass. On its return back to the start of the threads, it is just as slow as the threading pass. When it starts the second pass, it goes extremely fast, ruining the first cut. when it returns, it again moves at a very slow pace. I tried to install an older version, loaded only the necessary info to get the lathe motors to move properly, and it did the same thing. Please help as this is for work, and I have sold management on mach and all of its capabilities.Thanks in advance.
