Don't beat yourself up too badly... You'll get to watch, point, smile, and giggle when you hear me describe the same things shortly... Glad you got it figured out.

Wired up wrong

I'm lucky enough to have a manual for the machine. I just wish they put ask relevant info in the same area's not spread out all over. Are you working in a brother also. If so I'll take some better pics and send them to you and include the wiring I needed to get Mine ruNning in detail.

No, no... I am working on an Emco turning center. But I'm very ignorant and likely more bull-headed to boot, so will no doubt be bashing into things while trying to finish it up... ( as most of my recent threads will confirm )

Ok everything is wired correctly and working. All the limit switches are active.
I still have a little run away and joint following error on the x axis.
Anyone have any ideas. also may need to be talked through tuning the servo's
Thanks again to everyone for their help

Does the x axis follow jogging or does it runaway as soon as you jog?
(having a little runaway is like being a little bit pregnant you either have runaway or you dont)
runaway means that the feedback is backwards so you have no control of motion at all
once you have control of all axis (even with large following errors) you can begin tuning

As soon as I take the e stop off and hit the machine button it moves the x Axis. The y axis and z are OK. I am wondering if changing the x axis to inverted may have some thing to do with it.

If the X axis DRO is correct (correct direction for X) you will need to change the analog output polarity
Not sure how this is done with pncconf, in hal its done changing the sign of
hm2_[HOSTMOT2](BOARD).0.7i77.0.1.analogoutN-scalemax
(where N is the channel)

The dro is reading backwards, goes down in the pos dirrection, up in the neg dirrection.

In that case reversing either the encoder scale or swapping encoder leads is the solution
