So I just had the thought that what you're doing here is essentially building large CNC tattoo machine.. Dear god I hope nobody tries to tattoo themselves with this thing..
I did have an idea though, and I don't know if it will work or help or cause problems so I'll just pass it along and see where it goes. So obviously in this cutting machine, the point of the needle is doing all of the work, simply knocking out a little bit of material on each stroke, and if you go too fast the needle starts to flex and can potentially break right? Well I'm wondering if it would help to add a little bit of a knurl to the last quarter inch or so of the needle shaft to give it some grit and possibly allow this machine to move along a little faster? I had the idea because of the mentions of using a MIG welding tip for the guide tube, you know the little round brushes you use to clean your MIG tip and the tip of your Oxy torch? What about something like that with a sharp point on the end? that way you not only have the puncture action, you also add a little bit of sawing action.
Here's an image of what I'm talking about, sort of hard to see but hopefully you get the idea if you have not seen one of these before..
