Re: Ben's 2.x Laser Build

Ben,
Did you ever complete the transition to the mesa 5i25 card? I'm in the process of moving mine to that card and I'm wondering if you implemented a watchdog/charge pump.
The mesa card outputs are high before any configuration loads so if linucnc is NOT running at all, pin 17 is high and the laser fires. Obviously this is a safety problem. I posted to the linuxcnc forum and it looks like this is by design and a watchdog is the right way to go. Anyone else using a 5i25 with the buildlog pololu breakout board?
