(not really) New machine geometry for plasma

Hi all,

I just saw a ##### ad on #####  facebook for this : arcdroidcnc.com . A bi rotation arm that hold a plama torch. Simple and compact.

I already saw this kind of machine for pcb engraver (from elektor journal, in europe), and although for metrology devices.
I think it could be interesting, for people like me who don't have enough space to build a classic gantry plasma table. I need to stop filling my garage with machines.

I don't have the time yet, but I may be interesting in trying to make one with linuxcnc. At least trying to use this kind of geometry.

Any advices ? Does it already exist with linuxcnc ?

It is a scara robot. Hard to believe no one has ever done one in linux cnc I guess a 2nd hand one without controller is very affordable.

Maybe all you need to check is scara kinematics, scara robot, 4 axis robot.

It help a lot to know the right name !
The most interesting thread I found is forum.linuxcnc.org/10-advanced-configura...-kinematics?start=10

One of the video we can find on the web

So, scara robot are definitely just another kind of config already implemented.

If you have no space you can mount a Kuka robot on the seiling.


But I think plasma makes some mess, so a big feature is the water tray.
I skipped any ideas of laser or plasma. Laser I find too expensive for my hobby. $$$ and a plasma has to compete with the local laser company that cuts things for a small fee.
