My friend just purchased a used ShopBot PRS: http://www.shopbottools.com/mProducts/prSalpha.htm
His has a 96" x 60" work area.
I'm hoping to engrave and cutout panels on his ShopBot.
He's already made a ring and pinion gear for his flat earth models using it.
It's a pretty amazing tool.

Re: ShopBot CNC Router
that sounds like a real production machine.... did he get the alpha with the closed loop?
2 mil repeatability is pretty decent for that size table.

Re: ShopBot CNC Router
I forgot to ask but based on the original price he quoted ($19,995) I think its the open loop version.
The cutting speed for some materials is limited without feedback.
Sort of like slew rate limiting I guess.
His bits will cut T6 aluminum.

Re: ShopBot CNC Router
nah more like checking it's work... you can cut slower and ASSume it can always keep up. With feedback it will tell you if it can't keep up.mediatechnology wrote: ↑Tue Aug 22, 2017 3:01 pm I forgot to ask but based on the original price he quoted ($19,995) I think its the open loop version.

I wish I had room for one. I've thought long and hard about a setup and i just can't see it happening given current circumstances.

The Shop Bot cuts the ring gear and the astrological formations on the dome prior to vacuum-forming.
