I set up my bar puller last night and the physical aspects went well but the G code did not go well at all. The lathe is a week old so I know nothing about it. I can not get it to respond to any G code commands with the spindle unclamped. I looked through the settings and could not find anything to do with this situation except the option to disable the foot pedal. I was able to get the program to run through the M11 and unclamp the collet but that's where she locked up.
I would appreciate it if someone could give some suggestions on the sequence of events or movements they use to pull a bar and maybe include the G code they are using to accomplish it. I did notice that sometimes my collet would spit the bar forward when it unclamped. I would think this could complicate the pulling operation. Do you position a tool in front of the bar to limit the amount the collet can spit the bar?
This has to be a lot simpler then I'm making it.
I found the information on this forum to keep my spindle from starting and stopping with every tool change, that was a major improvement in its self, it sure is great to have forums and responders to point these things out to us amateurs.
I'm still looking for the number of the parameter that determines the amount of time the air flows through the spindle after it shuts off. Mine runs 5 minutes after shut off which seems to me and my compressor to be a little excessive.
