Breakout boards
« on: November 03, 2010, 01:39:57 PM »
Are there any recommendations for a BOB? I am looking at the CNC4PC C11 and CNC4PC C11G.
I am using Gecko G320s.

Because the gecko 320 already has opto isolated step and direction inputs it is usual to use a passive BoB similar to this http://www.cnc4pc.com/Store/osc/product_info.php?products_id=131
Often fitting two lots of opto isolators on step and direction (active BoB) has caused problems.

Did you mean to send me to the CNC4PC C13? Their site says:
"Do not use this board for wiring Geckodrvies, these drives require 16 milliamps signals, the parallel port can only deliver 10 milliamps. Using this board for these drives can cause lose of steps and unreliable operation. "

For use with Geckos, the cheap, simple, buffered (not opto-isolated) boards from Homann Designs work great.  And at about $30, they're dirt cheap.  Add one of his spindle speed controllers, and you've got everything you need.  And Peter Homann is a member of this forum, so if you need help it's just an e-mail or PM away.

Thanks, I already ordered a CNC4PC C11G. I will most likely use all of the included features.

Ooops sorry, my mistake. Looks like you have made a good choice with the C11G.
