Hi Todd,
I was wondering this also, at least can I call a function or similar
also, I think its a subset of VB scripting and can call some
predefined( not user defined (?)) routines Art has setup. The manual
covers some specific macros, buts its really murky if your trying to
do your own stuff. I'd like to see a bunch of real world examples of
macros for Mach2. (Actual scripts with all the content explained).

It'd be nice if we could post a 'library' of them in the files
section to help all of us.

Hi-
Is the a way to execute simple lines of g-code from a macro (

mo3,

g01 etc. )? If so what is the proper way to enter this info into a
macro.
Thanks

I agree it's murky! Documenting macros seemed a bit like writing the
user manual for a Swiss Army Knife!

It would be very helpful if you and others on the Group would like
to post explaining what you would like to do in your macros or,
perhaps easier, what you cannot do at present in Mach2. For example
is it to make MDI easier through less typing, to get round problems
with an existing post-processor, to control special features like a
part catcher etc.

With this sort of background established, I will try to document
sone more interesting examples.

Murky indeed...

Macro's were originally designed so I could reuse code, but they didn't
work out that way. Instead they are used to create usefrull subroutines for
specific purposes. Doc's are a little sketchy. John's idea is a good one, as
functions are needed I will add more. This is a troublesome area however, as
the macro's are run in a separate thread, so unknown interactions may occur.
This is evident in the serial output macro (on my immediate list for
repair) in that while it runs in testing mode, it will not transmit during a
program run. I will be spending some time to strengthen this over the next
little while to allow more complex programs with more stable interaction.
I'm attempting to make the main interpreter loop stop until the macro thread
is finished. This may cure the serial problem and allow for more
functionality. I have many requests for more output, so I am trying to make
the macro facility be able to transmit bytes to port addresses unknown to
Mach2, this would allow a 48pin IO card, for example, to be configured and
used as M-Code I/O no matter what card is desired. It may be the solution
for IO required for toolchangers and such.

I'll get back to you on specifics as I go. In regards to the question, "Can
I execute G-Code in a macro, yes, I believe the command is GCode("G0X0") for
example, but I will have to look this up...

Thanks,

Hi John,
I am just trying to find if you can issue simple g-code
instructions and pile them in a macro, I would like to take standard
gcode files and install calls for a m50 macro and have this macro
control cut speeds, output signals, dwell times, offsets etc. this
way I could alter the macro to make the same g-code file work with
different thicknesses, cut speeds, piece times etc. What it boils
down to is I would like to know if I could take something you would
type into the mdi window and insert it into a macro.
Thanks
Todd

Sorry, I didnt mean any offense, just needed to de-murkify my self:-)

That's very useful, is it mentioned in the docs and I missed it? -Lee

Your use of Yahoo! Groups is subject to

I guess its not really as important as I used to think, the current
activation signals are really all that are required most of the time.

I was interested in macros to create custom M commands to control
special features particular to a machine like you say.

One case was the arc startup delay for a plasma control before I knew
about using the dwell Gcode. I was going to use the macro to set the
feedrate really low for a time period, then go back to the commanded
speed. Then I found the dwell Gcode which made more sense, and then
tripped on the the related Mach1 'feature:-)' on the first occurance
after a Estop or fresh startup. Art said he killed that rodent in
Mach2.

But I still think the macro docs are murky nananananaa ;-)

I am sure no offence has been taken.

The function to execute G-code is documented in manual revision A2 -
sadly this is of little use to you as this revision also covers the
function key screen selection and XML profiles (as in Release
Candidate 7) but, as RC2.2 is still suggested for mainstream use, I
have not published it yet to avoid confusion!

The function as I have it is:
code (LPCTSTR block)
and will execute the commands in the string (VB script variable or
literal) that would be valid as an MDI line.
e.g. code ("F100G1X1Y3") in a macro will feed at 100 units per min
to 1,3

Thanks for your input I will definitely improve the explanations -
perhaps everyone should have somethink murky in their life though ;=)

Best wishes

I have been trying to get the g code to run in the macros as well and
have not been successful. I think I am doing it wrong ;o) … Is there
anyone having any luck getting it to work?? What I would like to do
is change the tool change macros (G00 G53 Z-.1).

Thank you
Brian

Actual code is without the paren's as in

code "G0X6"

This will execute a move to 6 in X, haven't tried G53 yet.

Thanks,
Art
www.artofcnc.ca

Yup works fine on mine.. Save just the line

code "g0 g53 x6"

in a file called M60.m1s and call it from MDI with M60, the tool will move
to Machine coord X 6.

Thanks,
Art

Thank you that works GREAT and the G53 works too

Thanks John,
Your method works perfect. code ("F100G1X1Y3")
