step and dir pulse problem Mach3

[dazp1976]

Hahaha taking the mick , sorted the Z axis it was a loose connection , so all i need to do is sort probe and e-stop out.
Also Jazz the 10v on the vfd does that need a wire going from it to anywhere.
Many Thanks.

No.
The vfd 10v is to give power to a manual 3 pin potentiometer. Then the pot dial adjusts that voltage and sends it back into the avi input via the wiper based on where you position the dial. Then it has a 3rd wire that goes to gnd .

That's how that one works.

If you did want to add a manual pot you can use the analog inputs on the axbb-e.
There are 2 on it so you could manually override both the spindle rpm and the feedrate using the wiper wire on a 3 pin dial if wanted.
I'm doing this on my 300eth.

Glad you figured the Z out.
