I have mach4 up and running with a hicon board, I have my probe working,( LED lights up when activated, ) I have motin, ( I can run gcode) but when I go to the probing page, and click measure Z
I get a ERROR: invalid gcode. I have searched and researched but I can not figure out how to get this to work. I can do a g31 z-5 f10 and that works as well. it seems to be something wrong with the measure z??  mach 4 ver 4.2.0.2803
I coiuld use some help or a place to start looking

thanks

on the probing screen, have you configured the settings tab and added the gcode 31 to it.

yes i have,  it worked (kind of) once,the first time I added the 31 to gcode box the Z started moving but in the wrong direction.
The next time I got an error no contact with probe.

ok I have got it to work i had to give it a z poistion of -5 but it is probing, I can't seem to find the place to give it my touch plate height??

See this thread for help http://www.machsupport.com/forum/index.php/topic,31367.30.html

There is also another one called "Auto Tool Zero" that might help. It talks about screensets to use as the basis.

The easiest way to do it in mach4 is to use the probing screen and use the measure z, once the probe has touched you can then switch over to the offsets tab where you will find a box for your gauge height and set z

I tried that but I keep getting unexpected results I must not have the correct settings or procedure. every time I probe it keeps setting my g54 z in the fixture table. but never give me the correct z in the dro

In the top right set this on measure only before you start the probe
