Building a Hadron

I've been fairly busy with work and the past few months and my 3D printer has pretty much taken the back seat.  But one of the things I have been doing is gathering the parts to build an OrdBot Hadron.  This was given a big boost by the successful funding of a European MakerSlide project on

This weekend most of the parts have finally arrived and so I started the build.

The Y Assembly
Some of it went smoothly, but I found that one of the laser cut parts, the Gantry Plate, was totally the wrong size.

Upon investigation I found that the DXF file I originally used was wrong.  Fortunately the others were OK, so I only have to get that plate re-cut.

Serves me right for forgetting the old adage 'Measure twice, cut once'.  In this case, check that the dimensions make sense before sending the DXF off to be cut.

So project is back on hold until the reworked plates arrive.

I had the laser cutting done by 4D Modelshop in London.  An excellent service and really helpful to a novice in Laser cutting. I highly recommend them.

More once the new Gantry Plates arrive!

  1. That's a neat looking machine! I look forward to seeing more of the build.

  2. Thanks, I've been interested in building either this or a Rostock as my second machine and the ulule campaign made the Makerslide affordable.

    It will be a week or so before I get the new lasercut parts, the first thing I have to do is create a new DXF from the PDF file. The PDF for some reason has the right dimensions, whilst the original DXF is way out, e.g. one dimension is 95mm in the PDF but 112 in the DXF :(

    I was thinking about sourcing the parts for a Hadron myself.

    would it be possible to post the DXF files ?

    Best Regards

    At the moment I have them spread over a few files. Let consolidate them a bit and I will posts them up.
