RE: [CAD_CAM_EDM_DRO] A little bit of help; Always works!!!

I would like to point out that you don't have to buy little electronics just
because it is a little machine. When I started it was to convert a Sherline.
I choose to get the Camtronics 5 amp chopper driver kit even though the 2
amp unit would have driven the Sherline just fine. After I got the Sherline
up and running I decided I wanted a bigger machine so I bought a Shoptask. I
was then able to take the Camtronics driver from the Sherline and use it on
the Shoptask with some 250 in/oz of so motors. I then decided I wanted more
torque so I upgraded the motors to 55 in/oz and the Camtronics was still up
to the task. If I had started out with a small 2 amp driver I would have had
to replace it along the way. All the chopper drivers I am familiar with
allow you to adjust the amperage to suit the motor so you can throttle down
a big driver, but you can't beef up a small driver.
