OK, you set up your buttons as oem triggers.  Now you need to set what the oem triggers do.  Hood has given you the oem numbers for start, feedhold and stop.  They could just as easily be mapped to coolant on, off, for example by entering the approiate OEM codes.

Neptune, so glad your still with us and hate you had to go through this.  Thanks for shareing.  All of us need to hear about these things when they happen.  They are sobering reminders. 

Get well soon,

Luiz. i can't comment on either of those.  I have never used either of them.  I'll be using a PMDX 126 on the lathe.  It doesn't have differential outputs for the step and direction but adding a line driver will cure that.  There are many options for BOBs and motion controllers and new ones being added everyday it seems.  I can't suggest any for you, I can only tell you what I'll be using.  I chose what I thought would be the best options for my machine.  You'll have to do your homework and decide for yourself what would be best for you.

Luiz, you could add a differential line driver between the BOB and the AB drive.  This will convert your single ended Step and direction signals to Step + and Step -  Direction + and Direction -.  I don't know of any BOBs right now that offer double ended outputs for step and direction.  It should work fine single ended but I think the biggest advantage in making it differential would be noise immunity.  As far as the encoder for the job, this will effect your resolution and I wouldn't want to go higher than 35KHz with a parallel port which will in turn limit your speed.  Mach can go to 100KHz but if the hardware your using (PC/BOB) can pull it off or not is another story.  I would look at the Smooth Stepper and a differential line driver.  http://www.warp9td.com/index.php  and I saw some line drivers on ebay a while back.  I'm setting up a lathe right now with AB drives and motors and this is the hardware I'll be using.
