I'm trying to write a custom interface and using python api.
But when I try the command
s = linuxcnc.stat.
s.limit

I have as result:
(0, 0, 0, 0, 0, 0, 0, 0, 0)
Anyone can Explain me why?


regards.

Seems to be normal to me for no limits violated. What were you expecting?

I assume you just gave a snippet of your code...

Ok.. so i misunderstand command. How i can get size of software X limit? From Ini file?
I want to do a mdi command like:
cmd = "G0 X%" % xmin

If your wanting to go to the X0 machine coordinate the G code is:
G53 G0 or G1 X0

I guess it depends if you set your machine up in the normal way or some other way. Normally the machine coordinate X0 is the minimum limit of the X axis or just before the minimum limit

I simply use a wrog command for my purpose.
I get the X min limit from Ini file.
And then i use
cmd = "G0 X%" % xmin
      self.emccommand.mdi(cmd)
Thanks.
