Yes you need a license in order to do threading. Note also to "NOT" use the Turn Diagnostics plug in. Also manually set the VFD rpm. Have A read of Threading On The Lathe - Mach 3 Turn.

You don't need to manually set the RPM. I've got it threading just fine while allowing Mach3 to control the RPM. The turn diagnostics is what helped me figure this out.

Problem solved. Mach3 must have a license in order to use spindle feedback threading. You would think there would be a pop-up or some type of error that says "You are in DEMO MODE. You cannot use this fuction in DEMO MODE."

Something I noticed while using the turn diagnostics is that the threading data shows 1.#INF for the locked rpm, current rpm variation, and highest variation during thread.



I can't find any information on "1.#INF" other than another thread where someone is having the same problem. I think I am on the right track here but I need more input from someone who would know more about this. I find it odd that nothing is throwing any type of error or anything to show me something is wrong or out of sync or anything. The program just stops and waits.

General Mach Discussion / Mach3 threading problems

I am running a Patriot Shopmaster VFD and I am trying to do some lathe threading. I am running a canned threading cycle and I have the spindle setup to use feedback sync via a magnetic sensor on the spindle. I have verified that Mach3 is reading the spindle speed correctly via sTrue and a digital tachometere to verify the reading. When I go to start the canned threading cycle the machine moves to the starting position, begins to move into the work and stops shortly before it does any cutting, almost as if it is waiting for some type of sync or input. It does NOT do this when I disable the feedback sync mode for the spindle but when I disable that setting it does not cut the thread correctly. Has anyone else had this problem and if so what did you do to fix it? I can provide any other information necessary (I hope).

I am currently using Mach3 and in the process of transitioning to Mach4 (using demo version for testing purposes atm) for our pipe profiler. Using the Tomahawk 40A cutter we can cut 2" sch40 at 80IPM, we are in the process of purchasing a PowerMax 125 with the CPC package for a few added features such as OK to move and arc voltage out. The machine was designed and built by in-house. 1300 IPM theoretical max X (length of pipe) and 800 IPM theoretical max Y (rotation). We are running the machine at 800 X and 600 Y since it is powered with steppers without encoders. This is to ensure the steppers don't lose positioning. Currently using a chuck out a pipe threading machine. Looking for better, larger options.

I also have a 10'x20' format plasma table in the works, currently nearing the end of the design phase. Attached to the Y carriage is an infinity rotation +2 axis' setup.
