Very nice pen holder/actuator!

Thousands of dollars for new plotters? Do they even make them anymore? Used ones can be found for less than $100.

@justin – think they’re still fairly common in large engineering drawing applications.

I haven’t seen a plotter used for engineering drawings in years. Instead, they use large ink jet printers that look very much like the plotters they replaced.

I wish he gave us some specs on the driver he is using and if the price of it factors into the $20. Nice machine though!

I was thinking about PCB etching, this would be simplest and fastest etching, just draw layout picture on PCB and throw it to acid!

I have worked and visited at several mechanical design and engineering firms and I haven’t seen an old school plotter since the early 80′s. The zerox large format lazer printers spit out sheets 30×42 at less than 45 seconds each. The large format inkjet printer are a bit slower. Not as slow as that ploter – but slower. I would turn it into an engraving machine.

Wow. I recently failed at this project on my own. Cannot wait for your instructions.
