The G50 and G28 lines are the problem. Otherwise the Tormach PathPilot controller is good with output. This is just a face operation to keep it simple. I think the G50 has to do with a C axis that I don't have. Thanks for your help.

How can I strip the Mplfan.pst (default Lathe post) back to a simple 2 axis (X,Z only) post. I'm trying to post to a Tormach PathPilot lathe. I've reworked many mill posts but this is the first time working on a Lathe post. Mastercam 2022

I'm getting better using the debugger. It's much nicer than the old one in Mastercam X. I'm currently running X7 and using the mpmaster.pst. My last job at work was the IT focal for the Mastercam users. I did a number of custom posts including a custom drill cycle for a Fadal deburing holes on assemblies. It's jut been over 5 years since I've worked on posts. I can had write taping cycles until I can get it to output the exact code. Not sure if the dwell will ever change. That's a good question. I could see it may need to change if the spindle speed changes too much. It was allot easier to do right after I took the posts training at CNC. But that was 7-8 years ago when Mastercam V9 went to X.

I tried that already. It was close but not close enough. Had problems with the tool starting at the bottom of the hole. Then I had problems with the timing partially due to the dwell being before the spindle stop. Getting close but still not there yet. I'll get it eventually. It's pausing too long when the spindle reverses. The sample code from Tormach works great. I'm just hand coding tap routines for now using a manual operation.

It's been 4-5 years since I've worked on Mastercam Post files. I need to create or just replace the ptap$ section of code in the mpmaster.pst to create this output for a custom tap routine. I could really use some help getting back into this or help developing this cycle. This is an example of good manual code that runs properly.
