How to make M1** execute Gcode

So while I am recovering from my mountain bike accident [url] forum.linuxcnc.org/51-ot-posts/46365-wel...oing-to-leave-a-mark [/url]
I decided to work on the pick and place project again . Right now I am trying to figure out how to use M172 with a P number to facilitate
moving the placing head to a specific feeder location instead of manually adding that location in my G-codes.. I am still very lost as far as
bash scripting or programming in general. I have been trying to remedy that but sometimes I think it's hopeless. The code below is what I
have so far and obviously it doesn't work. Any idea's?

I don't know much bash, but I think that you are mixing bash and Python.

Does it _have_ to be M172? If you could use one of the remappable codes (M200-M999 or an unused one in the < M100) then you can use the canonical motion commands and have the motion added to the queue, so that it is blended etc.

(Works for me) 
 

But... I tried this inside a programme and it does _not_ work as MDI is not possible in Auto mode.

Back to the drawing board...

Drop the attached files in the same folder as your config and make them executable (probably necessary, though I am not 100% sure)

Then add the following to the [RS274NGC] section:

(ie, add a [PYTHON] section after the [RS274_NGC] section.)

This will currently give you a new "M201" command that takes a P parameter and moves the axes.

It doesn't seem to be possible to map it to M172, though.

 

Thank you andypugh I will give that a try. The only reason I specified M172 was because that was the M code I was using. I used M1** codes with a
P number for firing the feeder advancers. I don't know enough to determin when a pure bin/bash command should be used or a bin/python instead.

 

Hi andy the code I need to add to the [RS274NGC] section: that's the ini. file [RS274NGC] section: correct? Or is it a file elsewhere in the system?
