Hi tom37, You are quite right about that. There are just a few but's and if's involved as well. Using a MIG welder will require a good electrical and electromagnetical separation of the weld voltage and current, from the three-axis movement voltage and current. On top of that the MIG nozzle is quite stiff and heavy as it is adapted for hand movement, so the re-design would be very hefty, but yes, the functionality is there. Converting a CNC mill to 3D-printing, well that is a lot easier as it more or less "just" requires an extruder head clamped on the mill Z-axis and that extruder can very well be a REPRAP one. The downside here is that I don't have a CNC mill - but yes, the functionality is there. I could even think of a solution to have a special attachment for the plastic extruder so that it can be mounted using the CNC mills normal tool fixing means, then change from mill to print is just a minutes job. Well, we'll see where it goes. It is fun testing and trying new things. Thanks for your thoughts :thumbup: /Peter |

We use our CNC router for welding... Here's the TIG head: We also use it for stud welding, although I just realised that we don't have a video of that. Here's the welder when we first got it. It did take a bit of sorting out to eliminate earth loops and capacitive coupling. But we use these setups commercially. PK |

Great stuff :thumbup: Looking forward to the CNC stud welder - are you automating the loading into the collets? I have this little hand held stud welder that works a treat: http://madmodder.net/index.php/topic,10358.0.html |

PK, thanks for showing! As far as I could see, the TIG nozzle was mounted to the ordinary machine spindle. Is it clamped around the outside or held by a collet? This looks very mucxh like you could also fit a similar attachment for 3D-printing using ABS or PLA, it is just the extruder part that needs fixing. Really a multi-putpose machine! /Peter |
