There is a difference in the schematic, the Non Z seems to have what I presume is a voltage regulator? VReg it says anyway but not being an electronics person it may be something totally different. Dont really see how that would affect things anyway but its the only difference I saw.

Good point, but the physical properties of all the connections appear to be the same, so it shouldn't make any difference.
The Z obviously signifies some changes of the internals.

This is the kind of problem where an oscilloscope comes in very handy!

Yes a scope would be handy for sure but I am thinking there must be a setting wrong that maybe I missed in the xml but it certainly seemed to work fine here when I simulated the Index pulse. Will look at the xml again and see if I can find anything.

Ok may have found a problem, you have a ratio set for the spindle puley, unless your index pulse is geared then you shouldnt have that.

OK i tried changeing the spindle pully ratio like you suggested and its now working like a charm  ;D (i now have 1 in both pully ratios)

Thankyou both for all the replys and help, it is much appresiated.

Just sorry I never noticed it the first time. I was just simulating the input so never really paid attention to the time I was inputting the simulated pulses and wrongly just presumed it was showing correct.
