Thanks gene Hey you might know how to loop a gcode file
I want to loop a gcode file 50 times. Ideally using m98 and m99 But I'm a bit stuck on how to do it. Does anyone have some tips? This is for bar pulling in CNC lathe M400 unclamps chuck and m401 clamps chuck And I need some way to loop the g code On Fri, 27 Jan 2023, 15:12 gene heskett, <ghesk...@shentel.net> wrote: > On 1/26/23 16:42, andrew beck wrote: > > hey guys > > > > just wanted to let people know i just made a tutorial on custom m codes > and > > i couldn't find much info on it and wanted to help the next guy and > remind > > myself when i forget next time lol > > > > > https://forum.linuxcnc.org/10-advanced-configuration/48071-custom-m-codes-and-bar-puller-set-up#262959 > > > > > > and also if any of you machinists have good tips for bar pulling on a cnc > > lathe i would love the ideas i have never done it before > > > > regards > > > > Andrew > > > > I don't have a bar puller, not even a 5C collet, just an ER42 collet > kit.
