hello jdm033056 ,

the best Thing is to add it to your code.
 for example:

Code: [Select]


%        (1)
G91 (it is allways good to put a Header line in G-Code not only G91 or G90 some other basic's would be good)

G01
F50
Y-2
X2       (5)
Y4
X-4
Y-4
X2
Y2       (10)

this is one way of many's. do not use OEMLED(13) it is Flood LED

use 1200 and abofe

Hello,

your code will only work, if you are in incremental mode (G91), not if you are in absolute (G90)

simply set a OEMLed in your ATC macro, then macropump is able to check, that ATC macro whants to set the Output
and enable it.

first off all, you have to tell us how you start the homing.

by pressing Ref All Home button?

so if you are able to set PWM Output to OEMDRO(1200) code for macropump would be:

Code: [Select]

If GetOEMDRO(817) <= 8000 then
   SetOEMDro(1200,0)
Else
   SetOEMDro(1200,GetOEMDro(817)-8000)
End If


800

General Mach Discussion / Re: Getting a Handle on Tool Height

ok i try to explai, how i do it.

you have your XYZ probe and the tool setter. and you have to have a referenced machine.
your XYZ probe is the master tool, let's say tool99.
put a fixed toollength of 100mm in tooltable for tool99.

-now you do a probing with the XYZ probe at the tool setter.
-after probing your read the machine coord for Z-axis and store it in a OEMDRO (for example 150mm)
-anounce tool99 to System by G43H99
-now you can do a z probing of workpice surface with XYZ probe and Zero z for G54

-now insert next tool in this example tool1 and do a probe at tool setter
-let's say tool1 probes at machine coord for Z-axis 140mm

now you know tool1 is 10mm shorter than mastertool99.
fixed toollength of mastertool is 100mm so toollenght for tool1 is 90mm.
now, if toollenght for tool1 (90mm) is entered in tooltable, and toollenght is set
via G43H1 Mach will compensate this.


all this can be done within a macro.

hope i was able to explain the difference between Auto Tool Zero and Tool Lenght Compensation.
