Tom,

I currently have four axes - X, Y, Z(quill), and A(knee). These are all connected using IO8-15. I now need to add an additional axis, for the stepper motor that runs my power drawbar. What options do I have for where to connect STEP/DIR for the new motor? Is it only JP5?

Regards,
Ray L.

Tom,

Trying to sort this out, but it's confusing, and I'm especially confused by this line in the documentation:

"Setting Bit-6 high of the register can be set high to multiplex Step/Dir generators 0-3 from JP7 to JP4 and JP6." - Huh?? generators 0-3 can be switched to JP4??? Which signals end up on which pins? This is not indicated at all in the connector pinouts.

Here's what I think I'd like to do:

Move my X/Y/Z/A Step/Dir outputs off JP7. Assuming the documentation that indicates generators 0-3 can be moved to JP4 is wrong, I'd like to move them to JP6 using Step/Dir generators 4-7.

Put the new drawbar stepper on Step/Dir generator 0, 1, 2, or 3, on JP7, leaving the 3 unused channels as available I/Os.

Can I do that?

Regards,
Ray L.

Brad,

That diagram doesn't show any of the I/O mapping options for the Step/Dir outputs, just the JP7/JP5 defaults.
