General Mach Discussion / Re: Breakout Board
« on: July 31, 2011, 12:58:09 PM »
Hi,
i nice design, but my board is a lot simpler, but ot cheep design. It was derived from my need for a low cost reliable board with the features i need for my Lathe conversion.

i estimate my board will cost less than half the cost of the 122 and still have the features i mentioned in my first post.

If people have ideas they would like to see incorporated, now is the time to speak.

General Mach Discussion / Breakout Board

Hi to all,

 I am looking to make a breakout board with full opto-isolation on Outputs and Inputs as well as 2x dedicated 10A relays.

 The uses will be able to select from a further combination of;
 a) 2 out of 3 comprising 1x 10A relay, Charge pump and 0-10V for Spindle control.
 b) Channel Y Step and Dir or Y Step and Relay no4 (10A relay)


 i believe this board will adequatly cover Lathe and Milling use.

Your comments, recommendations and interest would be most welcome.
