all sorted. horay
ended up getting onto peter.
after discussing what we had found during the coarse of this thread the fix was quite easy. basically the issue was caused by the logic of the bob. i am no electronics guy but as i had positive logic (i think that is what peter called it) to was sending a 'flat out' signal to the bob all the time.
the dc03 status led should flash slowly when the spindle is running from a f5 start (start and run at min htz) and when it is commanded to increase the rpm the signal is sent to the dc03 and then the led will flash fast as it is recieving the pwm signal. i was getting the fast flash from first power up of the dc03.
the unit works great and i am now so much happier about the whole set up. i have put in to much time and money to have something this simple rain on my parade
thanks to all that helped me with this issue, i knew it would be such a simple fix.
maybe this simple fix will help someone else in the future.
