Converting an A3 printer into CNC machine - In Summary

In short, it's been an awesome project to do, and I would do it again in a heartbeat.  I've still got some tidying up with cable routing, etc, but it has had it's first run with a pen zip-tied to the Z-axis.  The results are pretty good, and the accuracy is nice to see. (

There will be some enhancements and improvements:

  • Upgrade the rails and linear bearings to 12mm,
  • Expand the Z carrier to accommodate a 52mm CNC spindle,
  • Put in a 400W CNC spindle
  • Make the lights on the dash go blinky blink :-)
I would also like to drop in a 4x20 character LCD screen and get some output from the Arduino...some sort of job status maybe?

So on behalf of Dasher (she's been sitting here listening to me typing this blog) and myself, thanks for reading.  Feel free to leave feedback or ask questions.  Dasher won't give a fat rats bum about feedback or questions, but I'll do my best to get back you as soon as.

In the meantime, please check out the video of the first run, and I'll update the blog when I do something a bit more exciting than an electronic sketchograph.



  1. Nice Build! Can't wait to see the video.
