I did get a speed pickup mounted and have been doing some threading,  seems to work just fine although I am using an older version.   .034 or something like that.

Also just finished installing a VFD,  my Harbor Freight motor died,  bad starting cap.  I had more trouble troubleshooting it to the cap than it took me to swap to a 3phase motor and vfd.
I went through the relay starter with a fine tooth comb until I discovered the leaking cap,  had that thing apart 6 times before the light came on.  Half the wires in the relay start/reverse were poorly connected, half loose, the relays were designed for larger wire and would not crimp down tight on the small guage wire they used.  That lead me down the path to thinking loose wiring.

Bill,

The Z axis is a servo motor, Kollomorgen, with about 3 to 1 reduction driving a 3tpi ballscrew.  The X axis is a 1125oz/in nema 34 with a 2/1 ratio, driving a 5tpi ballscrew.  I was a little worried about the reduction on the servo but it drives it just fine,  great resolution and speed much faster than I would allow.   The X axis has good resolution also, not as fine as the servo, but very good,  I use a 1/8 microstepping controller.
The speed of the stepper is not nearly as fast as the servo but more than fast enough for good rapids.

Rich,

On those other turn wizards, can you send those to me or let me know where I can get them.
I have done a few myself and would like to have those also, until I get brave enough to try out Lazyturn.

go into the configuration - ports & pins - spindle - change the m3 & m4 output#'s
or go to the outputs and change the pin numbers for outputs, usually #1 & #2  to correspond to your machine.

I do this upgrade,  email me at aminear@wyomingwireless.com for more info.

You should get a message  in the STATUS:  message line telling you what caused the reset to go off.
something like External Estop Requested, or Limit Switch Triggered

Then you can do things like disable your -- & ++ limits one at a time and determine which one is tripping you off.

looks like you are getting exactly what you should be.
Not sure why you thought you should have 1/2 volts with the pin off.

the direction pin will put out 5v or 0, depending on the direction you are traveling
the step pin will put out a pulse, 5v with a duration depending on the motor tuning parameter step pulse duration.
You should hookup your driver and try to run it.  Don't forget to get an enable output to it.

Noise most likely.  Where from is the question along with why now and not before.

How is your wiring, are all your signal lines shielded and grounded (one end only).
Do you have any VFD's ?

are you typing a g31 Z-1,

Show us some code maybe we can round up some help.

A lot will depend on your budget. 
How much can you afford to spend on your upgrade?
