Re: vertical operation

I had completely missed the sliders. Are they custom designed or some kind of standard order part? I will try to get a closer look at them when I visit your shop next. I also got a little curious… does the friction matter where they rub against the wood? Are they perhaps rolling on bearings?

And the Polargraph drawing machines made my day… :-) thanks for sharing that! 

That probably must be the simplest way to setup a pen plotter. I suppose Sandy could also have just used the EiBotBoard.
