hole macro help please :)
« on: May 10, 2009, 05:41:26 AM »
Hi guys..

This may seem a simple task to the guru's here but after playing around with mach for a while i have to admit defeat (ie: i reached the threshold where i stop being obstinate and ask for help instead)

i have a repetitive task that need to happen for virtually every ring i cut. so i have the gcode saved on my desktop for it.. it simply drills a  hole (6mm hole with 3.17mm endmill)  in the middle of a hub in the centre of a ring to allow me to pick it up 90' to a finishing pass on my 4th axis.. i have been playing with MachScreen for tweaking my mach interface and i was thinking it would be cool to be able to add a button that would simply drill this hole for me. the example attatched is round but i hve a variety of hubs so i was hoping to add another screen to mach and have a few different hub buttons.. once i figure out how to add one the rest will be easy.. i hope :)

some clues to get me going in the right direction?

posting images and the gcode as an example.



Thanks in advance

Chris :)


[edit] aded rhino hub to help this post make more sense.. i hope

Make the macro and store it in the macro fiolder of the profile you use with a name such as M111.m1s  (User macro should be over 100 if I recall correctly) then its  just a matter of having a VB button on your screen that calls the macro, all you would need in the button is code("m111").  Incidentally calling M111  from MDI or code would also do that macro.

How the macro is written depends on what you need to do but  if its simple then its just a case of
Code("G0X0Y0XZ2")
While IsMoving()
Sleep(10) 'the sleep should not be needed if using one of the recent revisions of Mach
Wend
Code ("G1Z-5F40")
etc etc


You will may need to add spindle calls etc, all depends on how you want to do things and how your machine is setup.
I am not good enough at VB to rattle things off in seconds and it often takes me a few hours to do simple things I want to do but in the end it all works out and the sense of achievment is a nice thing for a thicko like me :)

Just tested things out and looks like the VB will wait until the code is completed before executing the next line so probably no need for the
While IsMoving()
Wend

but as said I am a thicko when it comes to VB so test with caution ;)

Phi next to some I may be  a genius but there are many more that are geniuses when compared  to me ;)

Test and see , easy enough to do, just open Mach copy your code and then go to the Operator menu and open the VB editor. Paste in your code and then add the Code(" to the start and ") to the end, Press the green arrow and you will either get a syntax error or the code will run correctly, I suspect it will need to be line by line though.

Ok just tested myself and as suspected you will need tto put it on each line, you might also need to put a G0, G1 or whatever on each line that involves axis movementl.

thanks man.. gave it a whirl and got syntax error..




some of the code is huge!  i will have to brush up a bit or manually load code for now.. occurs to me it should be easir to insert a section of gcode into a macro?

thanks for all the help man :)

You may be able to call the code from a macro, sort of like calling a sub but afraid I dont know enough about that.
