combination machine.

[pierantoine]

i was thinking of this yesterday :-)
if i had to do this i will make it with 2 gantry on the same bed when one works the other is totally parked at one end.
the Milling one would be strong, with ballnut.
the laser + printer head would be fast with belt and pulleys.
don't see too much interest with a laser diode for cutting, but will work for wood marking.
cutting PMMA etc needs CO2 with a invisible infrared pathway made with dedicated head, mirrors etc available on ebay

it sounds interesting...
