It didn’t work John, had to use the E-Stop again

How do I find out if the probe is registered?

If the diagnostic screen shows the green light on the digitize and touching the plate on/off the light also turns on/off isn’t this an indication the probe is working?

It happens so fast, I remember the second try I touch the plate twice with the alligator clip, the first didn’t work but the second time it did go up.

Should I use 120ohms resistor?

Apologies John, one of my probe connections was loose and after tighten it now the probe stops but it doesn’t go up, just stops. I did it a few tries using the script/midi with the same result.

The last line on the script says G1 Z1, perhaps it should be –Z1?

I hope I don’t do anything else stupid

Hi,
a block like:
g31 z-1 f20

will cause the machine to travel at 20 in/min to z = -1 inch or when the probe activates, which ever comes first. It does not turn around and drive upwards again.
It will, but you have to tell it explicitly what to do, for example:

g31 z-1 f20
g0 z1

The g0 z1 will cause the machine to drive to z =1 inch, presumably above the material, but only after Mach has latched the probe values into the pound registers.

Thanks Craig, but the last line on my script is “G1 Z1” and tomorrow I will change it to “G0 Z1”.

Reading the User’s Guide again (see picture) I noticed pin 15 where the probe is connected already has a resistor and I have set the jumper to pull-up. Tomorrow I will remove the 1K resistor I installed and hopefully all will be fine.

try writing "Code" rather than "code" in the last line.

Starting work late this morning and I hope to finish this subject today

I will do the change as you suggest John, thanks

Unexpected visits delayed my todays work…..

Finally the probe works and I don’t know if changing the “code” to “Code” had anything to do with it. I attach 3 pictures to see the layout. I’m not setup yet to take a video of the probe working but I will be pretty soon.

It’s possible the problem was related to my motors because I discover there may be a problem with the motors despite that they all jog properly and I will start a new thread about this subject.

Your help is much appreciated

"Code" is a defined command in the visual basic assembler, "code" is just a word.
