Hi, haven't been on here in awhile. I am STILL using version 1.84 on my lathe, and have had great success with threading and found no reason to upgrade, especially after the massive threading problems that the newer versions seemed to suffer. But, I usually make both parts of a thread, the male and female pieces, and have no issues. However I recently had to do some very long threads that were to screw into a deep threaded hole, and found that the pitch is off by maybe a half pitch over 1.25" of length, and nothing I could do would fix it. So, wondering if the newer versions of Mach have that issue fixed, and are as stable as my old reliable standby 1.84?
