Can someone show me the thread that describes how to do this, or please explain it to me in terms a 10 year old can understand?

I would greatly appreciate it.  I need to know what program to put into mach three to autoposition like it is doing and also need to understand the electrical circuit, along with where those wire's go on the parrallel chord to the computer for the power and feedback.

There may be one on this forum, but I don't know.  I do know of a description on how to do it on the Mach board on cnczone http://www.cnczone.com/forums/showthread.php?t=56079

As far as I know the software for the "probe" is already in Mach 3.

Any "metal" object is placed on the table, and the tool moved to it. When the tool touches it, it stops. (The metal object must be electrically isolated from the table ) A wire is connected to the metal object and fed into LPT1 input pins and the Config/Inputs/Probe is configured as the input, "active low". If you notice a clip was put on the tool to help with earthing the "target" when touched, but apparently this is not always required.

There is a similar post submitted by Benny further down the main page "Check out this post"

This appears to be a very useful tool - can anyone tell us if this is in Mach3 - and what the syntax is ???
Not me driving the engine - I'm better looking.

Both links I gave are for touching off with Mach.  The first one is the same thread as Benny links to.  Both are using a device with a wire connected to the parallel port.  One uses a macro and a new button on the Mach screen, one uses a specific Mach screen, then adds to it using a small Visual Basic bit of code he wrote.

Thank you so much for the help.

Can anyone identify this board to tell me where I wire this setup to?

I'm trying to build retracts for my Turbine Powered Jet, and want to shorten the time it takes to reset.

Thanks again,

Sean
Picture of my jet.

Almost looks like one of autohec's earlier boards. The pinout may or may not be right.

Looks like you have no breakout board, may need to trace the ribbon to a useable input on the PP.
Good luck.
DAMN nice jet too,
RC
I understand from that document about the pins that are "input" pins on page 11.  However, I don't see anything like his picture on my board.  Does that mean I can't do this?  Or that I need to cut the ribbon on the DB 25 chord and splice in this magical wire?

Sorry I don't understand this.  I can build jets that go 200 MPH from scratch, electronics though, not so much :(

That's a Xylotex 4 axis stepper driver.  http://www.xylotex.com , you can download a manual, it will give you the pinouts for the screw connector block, compare that with the instructions for Mach and you should be set.  Find the correct input pin for Mach and the matching pin on the screw block on the Xylotex board.  There's probably a pullup resistor in there too, don't miss that.  I assume that the threads I linked have that information, I haven't had time to read them completely through.  If you can't figure it out, post back.
