Looking to upgrade from my JGRO router for larger work area. When I built the machine back in 2009 I used 425 oz Kelling motors, Kelling drivers and a controller board. All of this is still working and mounted in a control box. I would like to reuse the electronics on a new machine.

I have the plans for the JOESCNC Evolution and starting to price out a 4x4 machine. I am also thinking should I look for an older machine that needs new electronics.

Which is more cost effective?
