It looks like you have the datum on the bottom face in Vcarve.

General Mach Discussion / Re: Can Mach3 Do a simple loop to increment a variable?

Sorry for the error, I was thinking in Mach4 mode, I had forgotten Mach3 needs the square brackets.  How soon we forget lol

You can call a sub to do the work.

E.G.

%
O0001 (MAIN)
#100 = 0
G00 X0 Y0
M98 P2 L50 (loop 50 times)
M30

O0002(SUB)
#100 = [#100 + 0.003]
G00 Z-#100
M99
%

Or

%
O0001 (MAIN)
G00 X0 Y0 Z5.
M98 P2 L35 (1ST)
G00 X10. Y5.
M98 P2 L35 (2ND)
G00 G90 Z10.
M30

O0002 (SUB)
G00 G90 Z1.
G01 Z-1.  F25.
G00 Z1.
G91 X-.003
G90
M99
%

If you are short on outputs you could use a manual switch.

The easy way is to put the output from each probe through a relay and switch the relay with an M code to select the correct input to send to the G31 input on the CSMIO.

G53 is an absolute unchangeable machine value that is set to zero by Mach3/4 after going to the machine home position.

G92 sets the fixture position.

G10 sets a new value in the selected fixture offset.

G52 sets a local fixture offset.

Have you got soft limits turned on?

I hope you are not using the pirate Mach3 & licence file that they provide!!

If you are then get rid and download the demo version from the web site, remove and replace then start setup again.

We do not usually help people that use this type of board due to the piracy issue.

It might be best to have the home switches on a separate input wired normally closed in series and forget the limit switches for now.  Limit switches are usually wired through the e-stop circuit.  So you would have 3 switches per axis.

What breakout board/motion controller are you using?
