I have a brand new Gecko 4 axis controller with a Mach 3 license I'll trade for a good working 4 axis AH-HA Controller with breakout board. I know I'm taking the worse of such a trade as the AH-HA is a relic compared to the Gecko, but I have another AH-HA controller on another Techno Isel cnc that I've been using for 17 years and I already know the AH-HA inside and out. I haven't even set up the Gecko or figured out how to jog the machine with the new system. I know if I want to devote a little time to figuring out the Mach 3 software I'd probably be better off in the long run but I figured before I take the time to do so I'd see if anyone would like to upgrade at my expense which would save me the learning curve in figuring out Mach 3.  If you have a good working AH-HA 4 axis controller and the breakout board (no breakout board necessary with the Mach 3, it uses the printer port) contact me at   sherm@shermcue.com   or call   (513)553-2172 and we can discuss it.
