I have a few pics, i just have to pass to my desktop, my smartphone is on repair so i can't pass the pics directly :/

When i get the pics i post here.

Set your G55 to X100 Y50 and save fixture

Move to the Point of Origin X0Y0 on your material. then Zero the xy axis(that will set the g54 to 0,0)  the example just drills 1 hole then offsets the head and drills another hole in the same spot to prove the offsetting works correctly.

G00 X200. Y0. S4851 M3
N5 Z6.
N6 G81 X200. Y0. Z-10.866 F1000. R2.5
N7 G80
 
(Switch to G55 to offset to the 2nd head)

G55

N9 G81 X200. Y0. Z-10.866 F1000. R2.5
N7 G80
   
G54 ( go back to the original fixture offset)

G0 X0 Y0  (Go back to the original Point of origin)

M5 M9
M30

NOW do not get confused by what you see in the toolpath as it does NOT exactly show what the machine is going to do. Just follow the machine tool as it does the job IT will be correct.



Thanks!....I will try that!

I wanna make "hole and screw" path because the OSB panel is loose on the table, so the screw will secure the panel...but i will test the 2 scenarios ;)

Still not sure what your trying to do as your using the same Z move to do two things? Wont one of the heads run into something while they are both going up and down at the same time?

but as far as your numbers I would think your mixing imperial fixture offsets with metric gcode movements
150" * 25.4 = 3810mm and 50" * 25.4 = 1270mm ( that's why your seeing the huge movements)
you might want to make sure you setup units are in metric or use the equivalent value (just some more math).

I think the same thing, my units on the mach is "MM", and i tried to convert to imperial (X6 Y2 Z0) and the mach do the same thing :/

BTW, The second head is activated by pneumatic actuator and another guide, that's why i dont need to use Z offsets.

Hi guys,

I tried your sugestions but the machine goes crazy, i go on fixtures offset on the "config" menu, put G54 X0 Y0 Z0, on the G55 i put X150 Y50 and Z0 (my mach3 is in millimeter), then i put the G54 and them G55 on the second step, and the machine goes to the center of the machine, goes to X3000 Y1200 or something like that, them i go to the "fixtures offsets" screen and the values change to this crazy numbers...i'm not understanding what's happening  :-\

Fixtures offsets is the only way to do that?....I have to make this work fast and simple...

This is the code i tried:

Thanks TPS!  :)

This week i will test all the sugestions here  ;)

I found here one of the codes i was testing there, i'm using M9 to cancel the M8, but i think this code is before i found the delay on M8, this week i will test again:

I used a limit switch to return the cylinder, i just need a pulse to activate the system, the rest is made by an arduino with some basic program  ;D

I don't remeber my last tests, but if my memory is right the delay ou M8 activate the relay and after a few seconds they "reset" the comand, i think i have the code here of my tests...

Thanks!!!

And Thanks to everyone who posted here helping me with this problem!  :) :) :)

if you can get your drill coordinates in a text file,
write a little VB-script with reads the file and
executes the movements.

Thomas

Its easy to write this VB-Script?....I'm noob on codes and programing, i use rhinocam to make the g-codes and a little bit of codes "by hand"....my biggest experience on writing code is on MachTurn.

Ya-Nvr-No

All the cylinder system is already setted, the return is automatic whem the screw is flat on the panel... i was thinking on using dwell to make the delay, but i found on configuration a delay on M8, that is perfect for this "screw" head  ;) My only problem is with offset  :(

You put the offset on the mach3 config, right?....Them you only put the G54 and G55 with the coordinates of the holes?

Its a big panel, about 8 x 7 feets and 50 holes with screw distributed on this panel, so machining time is crucial, it's for an industry, big production...
