Re: [Emc-users] Execute MDI command, from hal pin

[Kenneth Lerman]

I've implemented some safe probing routines here
.
They are examples of subroutines that might be called by external switches
-- or in my case from buttons on a pendant.

Re: [Emc-users] Execute MDI command, from hal pin

[Kenneth Lerman]

The other half of the pins that Sebastian mentioned is that the commands
must be defined in the .ini file.

This

will
tell you that you can put things like:

   -

   *MDI_COMMAND = G53 G0 X0 Y0 Z0* - An MDI command can be executed by
   using halui.mdi-command-00. Increment the number for each command listed in
   the [HALUI] section.

The first such entry will be executed when halui.mdi-command-00 is
asserted. The second corresponds to -01, etc.

You might then write subroutines to do such things as jog in +X, -X, +Y,
-Y, etc. Those subroutines might save the direction of the last jog. You
could also have a subroutine to use your touch probe. It could be "smart
enough" to probe in the direction of the last jog.

I'm not entirely sure what you're asking for, but one of my machines has 
a hardware button coming in to HAL through a gpio, connected to a halui 
input which triggers an MDI command.  Check out halui.mdi-command-XX:

What is the MDI_COMMAND?

I think that if it is pure G-code then it can be an OCALL
and you can use that same format in your G-code.

Alternatively, perhaps configure it as a use M-code or a remapped G-code.

[Emc-users] Execute MDI command, from hal pin

[Nicklas SB Karlsson]

Anybody know about a method to execute a MDI command with g-code then on 
a hal pin flank?
