Python Module program_units returns wrong code

[jethornton]

program_units

(returns integer) - one of CANON_UNITS_INCHES=1, CANON_UNITS_MM=2, CANON_UNITS_CM=3

If you start a file with G21 and at the end change back to G20 program_units returns 1

gcodes returns the correct G20/21 status

There are no CM units and even the NIST documents state that.

this just returns task.programUnits, so AFAIU it is sync with the g-code parser which is probably not what the machine is currently doing (lookahead and so on).

You should probably get that info from the state tag.

[jethornton]

Which state tag is that?

[rmu75]

I think it should be bit index "GM_UNITS" (=0) in field "packed_flags" in the state tag.

I think it should be bit index "GM_UNITS" (=0) in field "packed_flags" in the state tag.

That information is not accessible through the python module, is it?

[jethornton]

No, only the program_units is accessible through the python module.

Maybe programUnits should be updated in emcTaskUpdate... can you have a look at active g-codes from within python? It seems those are updated from the current state tag.
