No Sam, we are not alone..................... 

Looking very good Tweakie.............. top shelf.

The completed circuit board, well more of a terminal board really as just about everything connects here. The board contains 3 voltage regulators (12V, 9V & 5V) and the logic IC's to drive the indicator LED's.

Well now the weather has warmed up enough I am back on the Laser Project, at last.
Connected up the final lot of wiring to the control panel, which looks a bit like a rat's nest but it will all be hidden from view by the cover, once I get it sprayed.

   

Checked all my work for silly mistakes and fired it up - Hey it works !!.

This is the first test piece, Wile.E.Coyote - thanks to Sam for the GCode.

That's one very tidy rat you've got there Tweakie.
Fine job .... VERY fine.
Thanks !

That's just awesome Tweakie. I think that's the fastest I've ever seen Wile be completed. You'll be cutting all sorts of things now, and hopefully sharing more vids, too! Thanks a ton for sharing.

Very nice job, Tweakie! Finally got to see it working

Now need to see how it cuts some hard stuff which I assume it was primarily made for.

Amazing stuff right there, my friend, look forward to seeing how else you'll be using this piece of art....er um.... I mean machine 


Thanks,
Dave

Very nice Tweakie, Good tunes too.

Thanks Guys, you are all too kind.

I really can't believe that it has been 7 Months since I started this project, still I have learned a lot in the process and goodness knows just how much extra weight has been added to my machine (I just keep bolting more stuff on) but it is very satisfying to know that I am well on the way to getting it all completed. I will post some more pics of the laser head as I get it all tided up.

                

Not everything went according to plan as I badly underestimated the size of the heatsink that was required for the 12 Volt regulator. The replacement here is a bit overkill but there was space on the machine to fit it !.

Tweakie.

Fitted a 10 turn potentiometer with graduated locking dial for the current control. Also the safety lockout key switch.

   

Finished and fitted the cover for the Rats Nest.

   

This is the display panel. The DRO indicates laser current when the laser is triggered and the LED's indicate the various parameters.

   

This is the front of the machine with all the extra stuff fitted.

   

Finally this is another test run with aluminum faced engraving laminate. The laser cuts through the ally skin with surprising ease.
