Always something to make for whatever reason.

So true.......

Thanks,

1) Are there keys already assigned for jogging the A axis?

.
Those are "home" and "end" buttons on my keyboard using Rev 3.041

All I can say is "WOW", Rich. What an unbelievable amount of time and work you put into this and I for one appreciate it very much.

Thank you very much-

Thanks Tweakie, and agreed, PCB's make the job look much nicer indeed, but I'm impatient at times so I did it the old fashion way with point to point wiring, lol. Turned out well and now you can see why I needed such a small fitting setup as the channel everything is housed in is very very small. The laser incorporated more compactly and closer to the spindle centerline will be a nice improvement as well. A PCB would have made it even better fitting but, alas, I'm impatient as we just learned seconds ago 

I will definitely be playing with PCB drawing in Paint Shop pro to see what kind of results I can get, and thanks for the helpful info once again-

Some pics for you all.
Thanks,
Dave

lol! I don't know tweaks, I'm going to have to do a little reading and a lot of learning about doing traces but I may just jump into it and see what I can come up with. Any advice on software to draw these things?

In the meantime, got my breadboard and did a little experimenting today,

Went with this array setup for the experiment:

C'mon Rich, I'm disappointed in you.....now when do I ever make things easy? Seriously, I want this to be like my other spindle light housing, but it will now incorporate my laser finder as well. It's a form fitting spindle light that I designed around the Taig Spindle. I've actually looked at the round microscope lights but they're not a good fit because I can't reach the ER16 collet nuts for the cutters if installed.

As I mentioned above, I actually bought a $10 LED puck light just to tear it open to see how "they" did it and they use those tiny surface mount resistor arrays which there's no way that I can eeven begin to solder those! lol!

Thanks for the thoughts, my friend, but I've already been there, lol -

Hi Russ,

Unfortunately that's what Tweakie was saying and it's not the "best" way to go as it's hard on the LEDs and it can get pretty warm as well. The best way I'm finding out (that I can personally do) is to have 7 "banks/arrays" of LEDs with a resistor for each bank. I think that I'll be able to pull that off even though I don't have much room to work with.

I wish I was good at doing circuit boards as this would be a breeze for someone who has a clue, lol!

Thanks again, Russ-
Dave

Some pics of a job off Gertrude, used for the RhinoCam+Minitech 3sided tutorial I just finished

Excellent as always, Chris 

And where may I ask can the tutorial be seen?

Thanks,
Dave
