Galil / Re: VFD Spindle control 0 to 10V (not -10 to +10V)

Yep that's OK and what I had planned to do, was just wondering if we could be crafty and save some standard IO, perhaps an idea for future. Not important though I have enough IO.
Thanks Mark

Thanks Kenny
No immediate rush, I'm not quite there with it's install yet, just trying to cover possible problem areas before the conversion point of no return and avoid too much down time.  Thanks for the offer of help. I just need to get a 0 to 10V signal for VFD with M3 and M4 relays the same as many mach users operate. Actually just forward M3/M5 on/off spindle motion will do for now.
I did even wonder whether for spindle use, and to save some valuable outputs, whether the Galil was better confgured if possible to use the step/direction signal for spindle direction, and the enable signal to start the spindle. Easy enough then to wire the enable signal steered via a step direction relay to the CW/CCW inputs on a VFD. Not that I've read enough of the Galil stuff to know if that's viable, or viable to mach.

Regards Mark

It's now Aug 20111. Can I ask what state the spindle plugin is in.
For a simple spindle typical mach user with VFD running a 0 to 10V control without feedback, whats teh setup requirement?
Do we need to put an SM link on the Galil card?
I see no box to select -10V to +10V or 0 to +10V in the plugin configure screen.

Thanks Mark

Not sure whether I've posted here or not before. I usually use the yahoo group, which communicates by email rather than having to log on all the time.
It also seems a bit silly to delete all the zero posters, many people just use this forum to study the problems and solutions of others.

Anyhow to comply, I am Dr Mark Vaughan, have a large Avon CNC mill under mach3, a Harrison M280 still under development, a large router in a crate somwhere on it's way from China which will be on mach3, and who know what else. Most of you know me anyway, so that should do for the post.
