10:22 <set_> Hello...I have a BBG attached to a board for a CO2 laser.

10:23 <set_> how can I test to make sure my power supplies are both used in a smart manner?

10:23 <set_> For instance. The terminal connectors are on both PSUs.

10:24 <set_> I know for sure what is on PSU 2 but PSU 1 is giving me issues so far.

10:24 <set_> The BBG may need to have common grounds from both PSU 1 and PSU 2. I am not sure as of now.

10:25 <set_> All I know is this...I have some open lines when testing for supplied logic.

10:26 <set_> Would I use a common GND like a large piece of iron or steel to test the open lines or would I need to find a part of PSU 1 that I can use for GND?

10:27 <set_> ...

10:28 <set_> This is the issue. W/out knowing what reference is my GND, is there still a way to test?

10:29 <set_> On PSU 1, I have three (separate) types of terminal connectors. All of which seem to be isolated. So, terminals 1-4 are my Line In/Out and GND.

10:30 <set_> Terminals 5-12 are various functions along w/ voltage logic and the firing of the laser outside of source.

10:31 <set_> Terminals 13-16 are 24v out, GND, and hmm.

10:31 <set_> Okay. I just needed to type it I guess.

10:31 <set_> Sorry.

10:34 <set_> I may just plug it in and see if I can get testing...

10:34 <set_> I have this enormous transformer that I think is used for higher voltage to the laser. This is open for now. Not good...

10:35 <set_> Nothing is plugged in. So, this is it. I am trying to configure what exactly can be used outside of the other end of the laser to handle my reference.

10:37 <set_> Or...the transformer is cutting back as a buck converter (AC/DC). Whelp, time to sleep on it (one day soon).

13:25 <set_> Anyway, no fretting. I will try to figure things out.

13:25 <set_> I panicked as usual.

20:11 <set_> I worked hard and poof.

20:11 <set_> Dogs showed up.

20:11 <set_> Anyway, this BBG is not goin' work unless I have time away from family, dogs, and bad ofood.

20:12 <set_> I think we just started a war in Italy.

20:12 <set_> ha.

20:12 <set_> Just kiddin'.

20:16 <set_> We just ate at the nicest place in town. Instead of chatting about electronics, I found poison ivy...

20:17 <set_> Everywhere! I was goin' to chat about the bbb and newer things in life. All I saw was ivy everywhere.

20:18 <set_> People were dressed nice, full of poison, and ready to not mingle. Blah.

20:18 <set_> sometimes it is hard to say beagleboard.org.

20:19 <set_> I am serious. I typed it and read it and know it as a local name b/c I use the boards but discussing it seems a bit hard on peoples' senses.

20:19 <set_> Anyway, I will just stay quiet.
