Dry-Erase Plotter

[Brendan]

Gang,

I'm inspired to try and build something that moves...I've recently come into the possession of some new (to me) whiteboards...I don't have them in front of me at the moment, but they're big...possibly as big as the one on wheels at SC.

So, I'd like to build a 3-axis plotter to have an Arduino or Microchip (and probably a PC) draw on the white-board.

I'm comletely ignorant of things that move...I'm *thinking* I'll need linear-bearings (like the big delta printer) and two (maybe 3 stepper motors)...and then a servo for the Z-axis (Pen up, pen down).

I've seen Whiteboard "plotter" set-ups with just two motors hanging above the whiteboard, dangling the pen on two strings...I'm not interested in that, as it seems slow, and not as accurate. I'd also like to avoid a screw-drive, and go with belt...as it seems faster.

Oh, and I'd like to keep this under $100 if at all possible.

Am I completely off my rocker here?

I know you all have lots of experience with CNC tables, 3D printers, so I'm hoping you all might have some insight.

Thanks!

Brendan
