Unfortunately, the vfd's I have bought are totally w/o even the footprint for a serial port on the pcb's. And yes, I've looked. > ________________________________ > From: Gene Heskett <ghesk...@shentel.net> > Sent: May 14, 2020 5:55 PM > To: emc-developers@lists.sourceforge.net > <emc-developers@lists.sourceforge.net> Subject: Re: [Emc-developers] > spindle status > > On Thursday 14 May 2020 13:22:18 Chris Morley wrote: > > There is no 'actual spindle RPM' in a NML message. > > You must use HAL for that and in fact it's possible that that is not > > available if there is no spindle feedback in hardware. > > There is, and their isn't if you don't have an encoder.
