RE: [CAD_CAM_EDM_DRO] Kit Difficulity of Camtronics Boards

Alan,

I have not used the new version, but I built the previous version of the 5
amp controller. A very nice controller when you are done and the new one
looks to be better. I would advise you that this is not a great kit to do as
your first one. Nothing wrong with the kit, but it is fairly complex and if
it does not fire up for you on the first go you likely don't have the
equipment to troubleshoot it very easily. For someone that has done some
electronics and build a few projects it is a great way to go and a lot of
fun.

Just to clear one thing up, all bipolar drives that I am familiar with can
drive a unipolar motor as long as it is a 6 or 8 wire motor (almost all of
them). They do not drive the motor in a unipolar manner, but as a bipolar.
Unipolar motors work just fine this way and actually give higher torque then
when driven as a unipolar.

You may want to consider going with an already built drive considering your
electronics experience. May as well give a plug for myself, I am offering
some new close-out original production Gecko G201 drives which are 7 amp
bipolar microstepping drives that will work just great with unipolar motors.
4 of them would cost you about what the Camtronics kit does and are factory
tested to work. Contact me off list if interested (timg@...)
