A PCI LPT card is not expensive and the right one may fix your problem if it is a 3.3v issue.

However there is good argument to be made for leaving the old one on the machine and only use it for that purpose.

Use the newer one for other general work.

Going by your description, having just changed computer, I would suspect that you have 3.3v signals on the LPT.

Most modern BoBs will handle 3.3v signal, but maybe yours is just on the borderline.

Yes that is correct.

I am suggesting trying this command.  Because you are hitting the A axis home switch before the Y.

See if it works.

Here is the relevant line from the wiki on refcombination command,

Sub RefCombination(Axes as Integer)

Performs simultaneous referencing on several axes. They are coded by ORing or addition of the following codes: X = 1, Y= 2, Z = 4, A = 8, B = 16 and C = 32.

So try, 

RefCombination ( 10 )  'ref Y and A simultaneously.

after removing,

DoButton ( 23 )  'ref Y
DoButton ( 25 )  'ref A

I looked at your XML and could see no issues regarding probe input.

While I had it loaded I tried a G31 move and it stopped when the probe input was emulated.

I don't know what else to suggest apart from try a clean reinstall of Mach.

Greg

EDIT:  Just had a thought.   

If you are testing on a computer without the driver installed then emulation of the probe input will not work.

Do you have the driver installed?

I am not all that savvy with computers how do I post the XML.  Also I have a legacy version of the software and there are 2 XMlL files do you want them both.

What do you mean by "Legacy Version".    You should probably be using the latest lockdown version.

The XML will most likely be called, "Mach3Mill.xml", unless you have made a custom one.  Just add it to your post as an attachment.

You had better post your XML and I will have a look.

Code "G90 G31 Z-30 F50" 'probing move, can set the feed rate here as well as how far to move
While IsMoving() 'wait while it happens
Wend

I don't see anything in this code fragment that would stop the Z movement once it has been commenced until it has reached Z-30.

G31 is a probe move, so it is inherent in the move to stop when the probe input goes active.

Sawdustman,  will the probe move stop when triggered if you manually enter the "G31 Z-30 F50" in the MDI?

When you say the probe lights, what do you mean?

Look on the diagnostics page.  When the probe "lights" then the "digitize" LED should light.

Greg

PS:  Are you using the LPT or another external pulsing device?

No real tip here.

I just am one of those odd ones who prefer to manage backups myself rather than have a program doing it automatically.
