  24       <div class="date"> 8th January 2023</div>
  25       <div class="body"><p>I watched <a href="https://yewtu.be/watch?v=jmKUV3aNLjk">a 2015
  26 video from Andreas Schiffler</a> the other day, where he set up
  27 <a href="https://linuxcnc.org/">LinuxCNC</a> to send status
  28 information to the MQTT broker IBM Bluemix.  As I also use MQTT for
  29 graphing, it occured to me that a generic MQTT LinuxCNC component
  30 would be useful and I set out to implement it.  Today I got the first
  31 draft limping along and submitted as
  32 <a href="https://github.com/LinuxCNC/linuxcnc/pull/2253">a patch to the
  33 LinuxCNC project</a>.</p>
  34
  35 <p>The simple part was setting up the MQTT publishing code in Python.
  36 I already have set up other parts submitting data to my Mosquito MQTT
  37 broker, so I could reuse that code.  Writing a LinuxCNC component in
  38 Python as new to me, but using existing examples in the code
  39 repository and the extensive documentation, this was fairly straight
  40 forward.  The hardest part was creating a automated test for the
  41 component to ensure it was working.  Testing it in a simulated
  42 LinuxCNC machine proved very useful, as I discovered features I needed
  43 that I had not thought of yet, and adjusted the code quite a bit to
  44 make it easier to test without a operational MQTT broker
  45 available.</p>
  46
  47 <p>The draft is ready and working, but I am unsure which LinuxCNC HAL
  48 pins I should collect and publish by default (in other words, the
  49 default set of information pieces published), and how to get the
  50 machine name from the LinuxCNC INI file.  The latter is a minor
  51 detail, but I expect it would be useful in a setup with several
  52 machines available.  I am hoping for feedback from the experienced
  53 LinuxCNC developers and users, to make the component even better
  54 before it can go into the mainland LinuxCNC code base.</p>
  55
  56 <p>Since I started on the MQTT component, I came across
  57 <a href="https://yewtu.be/watch?v=Bqa2grG0XtA">another video from Kent
  58 VanderVelden</a> where he combine LinuxCNC with a set of screen glasses
  59 controlled by a Raspberry Pi, and it occured to me that it would
  60 be useful for such use cases if LinuxCNC also provided a REST API for
  61 querying its status.  I hope to start on such component once the MQTT
  62 component is working well.</p>
