GRBL version

[benknight135]

Which version of GRBL is this intended for?

I tried running on the latest 1.1h release and the status messages are not interpreted correctly.

This is the section where the regex fails.

    def _update_state(self, line):
        m = re.match("<(.*?),MPos:(.*?),WPos:(.*?)>", line)
        self.cmode = m.group(1)
        mpos_parts = m.group(2).split(",")
        wpos_parts = m.group(3).split(",")

@benknight135 I noticed this issue as well. It's definitely a GRBL v1.1 issue...you can find more information about the changes here: https://github.com/gnea/grbl/blob/master/doc/markdown/settings.md#10---status-report-mask

I was able to work around this by doing the following: Make sure you're only reporting machine position by issuing the following command: $10=1

I also changed the lines of code you posted above as follows:

def _update_state(self, line):
        # <Idle|MPos:0.0000,0.0000,0.0000|Bf:15,128|FS:0.0,0|WCO:0.0000,0.0000,0.0000>    CXA
        m = re.match("<(.*?)\|MPos:(.*?)\|", line)    #CXA
        self.cmode = m.group(1)
        mpos_parts = m.group(2).split(",")
        self.cmpos = (float(mpos_parts[0]), float(mpos_parts[1]), float(mpos_parts[2]))

This essentially removes the "work position" reporting but hopefully that isn't a huge issue for you.

Target grbl is v0.9.

@arsinio Thanks for documenting a workaround for grbl v1.1.

Pull requests to prevent the regular expression from failing, are welcome. But gerbil should support both grbl v0.9 and v1.1.

I’ll play with it a little more and put together a PR which fixes MPos and WPos hopefully sometime this week.

Michael- thanks for all of your fantastic work on this library!
