well i have a working spindle orientation! once you have a vfd that allows a low speed 15 rpm accurate motor rotation its not too hard
just rotate until the input-index pin changes state with a m66 code then stop spindle it overshoots the sensor by about 10 degrees but its repeatable so just change the location of the sensor (aka index pulse and we are away) next bit of progress i am just trying to get done is to preload my tool i have a random position tool changer and have selected that option in linuxcnc ini file but its not preloading tool it sits there and waits for the tool to load instead of doing it while the program is running when i type t1m6 the IOcontrol tool prepare pin goes high then once tool is selected the IOcontrol tool prepared pin goes high and then the tool actually gets changed with the m6 command anyway do you guys have any ideas regards Andrew On Tue, Nov 8, 2022 at 11:20 PM andrew beck <andrewbeck0...@gmail.com> wrote: > Hey andy. > > I was just having a play and I can actually just sense the input-index > pin directly.
