ATC Project - Debug phase

So I had a look at various stdglue.py files, and there doesn't appear to be any significant difference between py2 and py3.  The py3 were updated with py3-compatible dialect, but the fundamental stuff didn't change.

I fiddled with some of the ngc files, and can see that the main toolchange.ngc is running, as the error I'm getting about named parameters is a third of the way through the file.  I think this means that LCNC is at least starting to process toplevel, remap, and stdglue.

I think I'm going to follow my own advice in the recent rack ATC thread and try to get the ATC working outside of Probe Basic first.  I just don't have the experience or knowledge to sort out so many new-to-me concepts and details in one bite.

So... next question to help me diagnose and monitor everything: how do I see the value of parameters?  I can open linuxcnc.var and read the numbers, but I'm not clear on how to view the value of named or named global parameters when LCNC is running.

Is there an MDI command that will display the variable?  Or do I need to open a second terminal and type something out?

Tommy - I think those are for hal component parameters.  I'm looking for system parameters used in g-code.

Like #<_selected_pocket> or #<local_named_paramter>

That Magic Comment was pure magic.  Thanks Andy.

Ok, so I can now read the global named parameter values.  More importantly, they change when I load a tool in the spindle with the on-screen button. Load tool #2, and #<_tool_in_spindle> = 2.  So far, so good.

Problem the next is if I change to a local named parameter, #<tool_in_spindle.  Maybe I'm misunderstanding, but this should be what stdglue & remap passes from the global to local named parameter(s).  In the sample toolchange.ngc file, there's the following:

;assign the variables passed by M6 to some parameters
#100 = #<selected_tool>
#110 = #<tool_in_spindle>
#120 = #<selected_pocket>

Those local named parameters aren't defined anywhere else, so they must (?) be coming from stdglue. Right?

If that's the case then stdglue isn't actually working, which is why I keep getting the Named parameter #<selected_pocket> not defined error when I try to unload the spindle to the ATC.  That particular ngc file simply calls T0 M6, which in turn references the toolchange.ngc file.

And if I set tool #4 to pocket #4 then load it in the spindle (via gui button), #<_selected_pocket> changes to 4.  So LCNC is working, and the global parameters are updating.

But stdglue/remap isn't passing the global parameters to the local named parameters in the various ngc files.

INI file path error?  Thought I had that fixed, but maybe it needs a relative vs. absolute path to the python folder?

[PYTHON]
# ***leave the following commented out unless you are using the ATC macros***
TOPLEVEL = /home/mill/linuxcnc/configs/HAL_rev32_ATC/python/toplevel.py
PATH_APPEND = /home/mill/linuxcnc/configs/HAL_rev32_ATC/python/
LOG_LEVEL = 8
 

I think it does, but I've attached it here in case I've overlooked something.

python folder contains:

toplevel.py (one line = import remap)
remap.py (one line = from stdglue import *)
stdglue.py (previolusly attached)
