arh , if i'm reading correctly , you wish to use an external output form your vfd to trigger ? , hence an input pin
the spindle at speed signal is internally generated within linuxcnc , using the spindle rpm encoder so therfore does not need an input from the vfd directly to use . so long as your spindle speed rpm is correct or within bounds of a few rpm it will work fine , On 29 December 2015 at 15:11, Sarah Armstrong <sarahj.armstron...@gmail.com> wrote: > you can use stepconf to produce a configuration , > you usually see a > sets spindle-at-speed true , this overides the spindle at speed > it may be in your postgui.hal file . > comment it out and you should be ok > > > > > > > On 29 December 2015 at 14:59, lloyd wilson <llwilso...@rochester.rr.com> > wrote: > >> I'm trying to add a pyvcp panel to control a spindle vfd.
