RE: [CAD_CAM_EDM_DRO] Gecko + Servos + Taig Mill

Hello Robin,

I am sure you will get lots of advise, but for the most bang for the buck
here is what I would suggest:

I would suggest you look at the Gecko G320 drives (servos instead of
steppers. The performance is better, but they are a little more work to set
up) Get the case, power supply, and motors from Camtronics, the driver
software from Yeager Automation, and the CAD/CAM from IMService.
You can get motors cheaper if you cruise E-bay, but you have to know what
you are looking for. The Camtronics ones are reasonably prices and known to
work great.

There are pictures of the Camtronics servo case with power supply on my
