ENTERING USER INFO INTO CODES

[TOMMYD]

I am setting up my auto tool zero button and got the code from the forum but don't know how to modify to my specs. I obviously don't know anything about writing codes.
 
for example;


PlateThickness = GetUserDRO(1151) 'Z-plate thickness DRO

  ?should this read?
      ? PlateThickness = .375 'Z-plate thickness DRO ?

                             OR

      ? PlateThickness = .375(1151) 'Z-plate thickness DRO ?


If GetOemLed (825)=0 Then 'Check to see if the probe is already grounded or faulty

? Is this my machine zero,can I jog close to plate ?
DoOEMButton (1010) 'zero the Z axis so the probe move will start from here

           
Code "G4 P5" ' this delay gives me time to get from computer to hold probe in place

  ? what distance does .75 represent  ?
Code "G31Z-.75 F10" 'probing move, can set the feed rate here as well as how far to move

While IsMoving() 'wait while it happens
Wend
ZProbePos = GetVar(2002) 'get the axact point the probe was hit
Code "G0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun
While IsMoving ()
Wend


  ? should I enter plate thickness here or does it know from line 1 ?
Call SetDro (2, PlateThickness) 'set the Z axis DRO to whatever is set as plate thickness


Code "G4 P0.25" 'Pause for Dro to update.


  ? is this set for 1" now?
Code "G0 Z1." 'put the Z retract height you want here


Code "(Z axis is now zeroed)" 'puts this message in the status bar
Else
Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if aplicable
End If
 
Thanks,Tommy

Plate thickness is taken from a User defined DRO on the screen. If your plate is .375, you can code it without using the DRO like this:

PlateThickness =0.375

? Is this my machine zero,can I jog close to plate ?

No, it zero's the Z axis in the current coordinate system.

? what distance does .75 represent  ?

The maximum travel of the Z axis during probing. If you want to start the macro at a location higher than 0.75, you'll want to increase this number. Note that it's negative,  -0.75.

  ? should I enter plate thickness here or does it know from line 1 ?

It's assigned in Line one. "PlateThickness" is a variable, and you're assigning it the value of 0.375

  ? is this set for 1" now?

Yes, it's set to retract 1"


I seriously recommend using a more robust macro for your auto zero. The minimal one you're showing here is open to a lot of possible errors, which can cause broken tols or even machine damage.

You might want to look here for a much more refined version.

Gerry,
  Thanks for the quick responce.I'll use the one you suggested,but I'll probably still be back with questions. Thanks Again ,Tommy

Gerry, It worked flawlessly the 1st time.Now all I need is to learn how to put an LED next to the auto tool zero button so I can test without going to diagnostics page. Thanks,Tommy

[ger21]

If you post your .set file I can do it for you.

[TOMMYD]

Thanks for the offer! I would like to try it myself.If it flops I'll be back. Thanks,Tommy
