We recently did a video talking about bar pulling on a 15L and in it I wrote a sub routine to use for commanding the bar puller. We’ll add the sub routine to Pathpilot with a future update but in the mean time I’ve attached it here so that any one can use it if they want to set up their machine to use a bar puller.

Here is the video where I go over use of the routine: Tormach 15L EZ Bar Puller/Automatic Collet Closer
Norman,
I love this approach with a sub-routine does that conflict with wanting to cycle a project for multiple parts with a single file? For example I manually coded my bar pulling inside of a G98 block for a total of 17 pieces from a single bar. Considering this is often how one would use the bar puller how does this code marry with the nc file for the part to get a completely automated code block?
Rich,
The lines that I added to the program for M99 in the video is all you’d need to run as many parts as you can fit in a bar.
Thank you,
Norman
nkowalczyk,
Forgive my ignorance here. Manual machinist for 10 years, just beginning my CNC journey with the Tormach 15L. Have been learning tons over the last couple weeks. For whatever reason the Bar_Puller.nc file you have posted for download has way more lines of code in it and looks way more complicated than the code you were editing in the video. I have tried making sense of it but cannot seem to figure out how to program and whether or not I need to remove any of the pound symbols. Can you provide more detail about how to program that file to set the bar puller up to run automatically in my part program?
