00:58 <set_> Whelp...I ripped it apart to make the BBG utilize some fancy technology for laser use!

00:58 <set_> It is in the works. Will it work?

00:58 <set_> Who knows? I sure do not but one thing, I will keep on trying!

00:59 <set_> I only have about 56 wires. I should be able to figure it out!

01:00 <set_> Wait a good half a year and watch the fireworks or at least the Class IV!

01:04 <set_> Gas and Electricity...what could go wrong?

01:06 <set_> two motors so far. That is the part that will need drivers. Done but the rest of the wires are a bit unidentified so far. Updates on the way!

01:08 <set_> I can trace the stops and estop so far. So, those wires are done. Now, onto what exactly comes out of the PSU? Hmm. I wonder...

01:12 <set_> It damn near took me all day to conquer the demo. of the machine. One socket head gave me the insecurities I have always felt. Blah.

01:35 <set_> GenTooMan: Do you know anything about laser drivers/PSU stuff?

01:36 <set_> Look here: https://imgur.com/a/c6MPpY5 does something?

01:37 <set_> The Stellaris is old news and cannot be updated or "used any longer." Updating to BBG!

21:02 <BeagleBoneAi-LCD> Hello All, I need some help. I want to use an beagleboneAI with an LCD/ LCD cape:  https://www.waveshare.com/w/upload/9/93/LCD_CAPE_Schematic.pdf

21:02 <BeagleBoneAi-LCD> there is someone that can help me?

21:06 <BeagleBoneAi-LCD> Im using debian: AM5729 Debian 10.3 2020-04-06 8GB SD IoT TIDL

22:26 <GenTooMan> set_, off the shelf laser drivers are available, however it depends on if it's a semiconductor (IE laser diode) discharge laser (uses a gas) or a pumped laser (uses a emission source to energize the laser). So I assume semiconductor you need to read the specs for the diode carefully. Further you also need to know the bandwidth you plan to drive it at. IE how fast you wish to change it's current drive.

22:48 <set_> gas.

22:49 <set_> I have a gas laser for use for now. I will keep on reading on.

22:50 <set_> I have a driver for it. BBG! PRU!

22:53 <GenTooMan> gas laser are not as simple to drive FYI.

22:57 <set_> I understand.

22:58 <set_> I have the built in driver and connections along w/ the hardware that handles PWM/GPIO/1/0, etc.

23:00 <set_> The issue so far is that drivers for motors (done) are expensive for running 24v through them, the Single Strand (heavy duty) power connection to the laser (done) is going to need a few days or prep work, and the rest of the PSU has these wires that are (so far) dysfunctional b/c I do not know anything about them.

23:00 <set_> ...

23:01 <set_> The PSU for all I know is a PSU/Driver/Thing w/out paperwork. Blah. Dang it.

23:02 <set_> GenTooMan: Is there a way to figure out what is PWM/GPIO/i2c or whatever that comes from the mistook lines/wires out of the psu/driver?

23:04 <set_> I have the o-scope but am lacking ideas so far. I will research the way i2c/gpio/pwm look in the o-scope so I can tell.

23:04 <set_> This may be a reasonable way to go about things. I can start small, 5v or 3.3v, and work my way up.

23:05 <set_> Too bad I do not have a filter.

23:06 <set_> Well...anyway. I know the company would not approve of me dismantling their machine I purchased but woof. They stopped supplying the correct resources.

23:08 <set_> The machine is '13 w/ a working laser (gas). The steppers still move, the laser fires, and the damn connection to the machine w/ their add-on/daughter card is, well, not getting anywhere these days ('13). Blah.

23:10 <GenTooMan> I suggest look at the given schematic for the Laser and how to drive it first.

23:10 <set_> None.

23:10 <set_> I know...that was my first resource to look at then but it never did exist.

23:12 <set_> I am the only one that knows about it! Aw. Ha. So, their Stellaris from TI is gone, unoperable, and the daughter card is no more (useless). It worked for six years. What can I say. They tried.

23:12 <set_> Money shifted hands. New ideas came in. People got shifted around. Blah. Okay. Blah. Not this chat issue or anything...

23:13 <set_> But...the BBG in question came w/ a nice schematic.

23:16 <set_> It says this, that, and then some. So, I use motor drivers, a GUI, and figure out what powers what...if I can. And then, I can try to configure the right pin diagram to let others know...!

23:17 <set_> It is not easy. You know this, man! One wrong move, poof. The whole atmosphere turns sour in the ole garage!

23:18 <set_> Hopefully, their silkscreen on the driver is a bit more helpful than the co. I talk messes of mess about companies. Everyone knows this about me.

23:19 <set_> ...

23:19 <set_> I just know I am missing the bigger picture. I could use 90w instead of 40w or galvo?

23:20 <set_> Fibers! That is where it is at now! Shove in and passed the metal!

23:20 <GenTooMan> the schematic can tell a lot in how to drive it

23:21 <set_> GenTooMan: There is no schematic. You mean for the XMOS or Stellaris?

23:22 <set_> These people at the co. did their own Stellaris. I knew I should not have cut the wires...I could have tested the wires in the housings.

23:24 <GenTooMan> what the ... well I guess it's totally done for yep

23:25 <set_> No!

23:25 <set_> It is not. Do you understand about the way to power something to get feedback from the oscope?

23:26 <set_> Fine.

23:26 <set_> No issue. The wires have been cut (trimmed) out of the housing (screw terminals), taped, marked in bunches, and now I can slowly move on.

23:28 <set_> And by "slowly move on," I mean move into more fascinating progress and tech.
