Peter,

I added steps 1 - 4 to the tutorial to save typing time.

Ok got servos running in open loop test of pnccon. How do I check the encoders to see if they are working correctly.

Also if anyone has any idea on how to keep the z axis from falling on start up I would appericiate the hints

Can you rotate the screws with the servos off?
You need to make sure that a positive voltage to the drives moves the axes in the positive direction. Then make sure that a postive move makes the encoders count up.
You can do this in the GUI. Don't power up the drives, set the GUI to show actual rather than commanded position, and move the axes by hand.

i guess there is some delay between the brake releasing and the drive enabling. What is break-release connected to? Ideally it would connect to drive-enable. Possibly with a delay component set to a small fraction of a second.

Ok found a few little hick ups on my part. 1st wired the limits wrong. Need some one a little bettwer then my on it. I'm a little lost

what I did was took the two leads from the limit switch (nc switch)

wired 1 end to tb8 pin 1

wired the other to a terminal block

wired 24v pos to tb2 pin 1
wired 24v neg to tb2 pin 8

wired terminal block to tb2 pin 2.

Also no position info from resolver/encoder.

I disconected the power to my z axis , removed it from the machine (easiest to remove) turned the motor by hand, no position read out change.
I was able to have linus move it also in a countinous movement. No change in the position readout.

The drives encoder outputs will not work without drive power
(but should work with the drives disabled)

(looks like disconnecting CN8 pin 15 will disable the drive)

what is the easiest way to just disable the drive
