OEM code 301 is used to call a macro that has been set as trigger macro.

The macropump/brain combination that you have used does not utilise the trigger macro.

Your on-screen button should just call the M615 macro.

Is there a keyboard shortcut to the auto tool zero button? I would like to map it to a controller..Thanks

[ger21]

You can add a shortcut in Screen 4 in less than a minute.

[jjacstcy]

How about 10 minutes for the new guy...Thanks Gerry as always!

[jzak3]

hey, Ger when I use my auto zero plate the z axis comes down and touches off the plate once, it doesn't do the second touch. after the first touch the z rises and stops 1" above the material, why dosen't it do the second touch off?

thanks'

[ger21]

Are you using my Screenset? If so, probably noise is triggering the probe input before the second probe. Most who experience this add a capacitor to eliminate the noise.

[jzak3]

no I'm useing the standard mach3 screen

[jzak3]

you also sent me a script once and I seemed to have lost it, but when I tried useing it it gave me a notice that something to the affect that it was unable to read it? I am useing a peice of pcb 0.060 thick. Thanks'

[ger21]

What script are you using?

[jzak3]

Message( "Auto Zeroing..." )
If IsSuchSignal (22) Then
code "G31 Z-3 F20"
While IsMoving()
Wend
Call SetDRO( 2, .060 )
code "G1 Z1"
End If

[ger21]

why doesn't it do the second touch off?

Because the script you're using only touches once. You need to edit the script to touch off twice.

[jzak3]

I found that script at cockrum.net, being a newbie and always looking for more input, is it reallly necessary for the machine to touch off twice? and if so would you be able to send me the script I need?

Thanks'

Just skimmed over the past 40 pages looking for a auto touchoff that has a double touch... Did I miss it or has it not been posted?

I had a quick attempt at making my own but no luck getting it to run.

Could this double touch method also be put onto the homing macros for x y and z?

[jzak3]

I used the script I found on cockrum.net and follwed the instructions and my machine only touches off once, but still works fine, I guess to make the machine touch off twice you have to edit the script to make it do that and I am not that savvy at editing script yet. Take your time and make sure to follow all the instructions.

Why bother with a double touch?

If you really want it though, try:

Message( "Auto Zeroing..." ) 
If IsSuchSignal (22) Then
code "G31 Z-3 F20"
While IsMoving()
Wend
Call SetDRO( 2, .060 )
code "G1 Z1"
End If
Message( "Double touch Zeroing..." ) 
If IsSuchSignal (22) Then
Rem **** Half the speed on the retouch
code "G31 Z-3 F10"
While IsMoving()
Wend
Rem **** The thickness of the touch plate is 0.06mm
Call SetDRO( 2, .060 )
code "G1 Z1"
End If

[jzak3]

Thanks' I will save this so when I am done with my new and improved cnc machine I will use it.
Thanks again

[jzak3]

hello, I noticed that there is a setting in the script for 0.06mm I am useing standard units and not metric, How will this effect my machine?

Thanks'

Since Mach is only looking at units change them like this:
(However, I doubt you'll be using a 0.002" thick plate).
Maybe, this is really the amount to back off and retouch by.
