Post the XML file for the profile your using for Mach3 so I can see how you have Mach setup.
You'll find it in the Mach3 folder with the same name as the profile you use and ending with XML.
Zip it up to post other wise won't allow you to post.

i made a right balls of trying to copy the XML file and deleted it instead. i tried to restore it but having no joy. i will set it up again and get it up a.s.a.p. sorry for the inconvience Jazz

Mach keeps a backup for you. Just look in the XML backup folder it will be there.

after pulling the little hair i have left on my head and trying everything i thought would improve my spindle issue i have stumbled accross what i think is my issue and solution. i had a single wire run from +10v (bob) to +10v (vfd). when i made off the control cable initially between BOB and VFD i just used 4 core,2 for the PWM and 2 for START/STOP, all sheilded. because i needed another signal for +10v I ran a single cable temporarily to test and this is where i believe my problems stem from. i unknowingly had the single cable next to a power cable and by chance moved it during the spindle running on its own and the problem dissapeared. Now i know why experienced builders keep the VFD outside the cabinet. i didn't realise how sensitive these signal cables are. once again a big thank you to Jazz for the time given in relation to this. everyday is a day for school .

Sorry didn't get back to you last night but I was in workshop late and never got time to look until tonight.
I'm relieved you found something because I couldn't see anything wrong with Mach setup and come to the end of what I could suggest.!! . . . Next step was a ferry ride to Limerick.!!

Grounding and silly Wiring issues are probbaly THE most common cause of premature Hair loss.

Ok it occured to me last night in my sleep that noise on the 10v signal still wouldn't make the spindle Spin if the relay was working correctly.
So I still think you have some issue with the relay not being set correctly. The 0-10v signal just defines the speed reference it's the Run signal and relays that controls whether the spindle turns or not.
I think relay is not being controlled correctly and the run circuit is still closed. Mach stops sending a speed reference when M5 or spindle button is toggled off but the noise on the 0-10v line is causing the spindle to still spin because the relay circuit is still closed.

So only thing I can suggest now (other than you've not wired it correctly which I'm sure you have.!) is that the BOB is some how taking over controlling the relay duty's and because in Spindle setup you have the Relays enabled your getting conflicts.
I suggest to test this theory you put the VFD back into using the on board speed control PD002 = 0 and leave the Start/stop to set to external control. (make sure the vfd speed reference is set above zero for this test) I think you will find the spindle starts again and won't stop and you can't control it using F5 which if was correct it would.

If I'm correct then try disableing the relays in spindle setup and see what happens.?
