cool pictures...
Biggest reason we are doing CNC related things now is that my poor old body got too banged up to haul it up and down the ropes anymore spelunkings...THAT TRUMPS...

Point in...

Well, you made us curious all weekend...so we finally checked one....and in design, it is said that a two motor design makes for rounder spheres, but three motor goes faster. We were in a bit...

I will endeavor to post two pictures to this.
Who is we? Myself, and three sons....the twins are 17 and their younger brother is 10.

Our question had to do with larger stones....not nec. the...

Well, it got me started thinking about faceting again....but making very small gems hasn't been introduced into my blood yet....how about much larger ? We did make a sphere machine and we also...

It is quite possible that the equipment you pruchased was an earlier method of marking...and worked a great deal like older dot matrix printers...only with alignments of lasers instead of alignments...

Sorry to be gone so long.

My 3 sons and I were building a larger plasma torch but that got put on hold. We lost the mom and family business due to cancer and I had to quit work due to messed...

GO!!

We started to convert a working laser ( we have two) into an engraving system earlier, but ran into snags in other areas, not the least of which was knowledge. (and lots of cash)

We would...

:cool: I wonder how these would work out? ($35 OR SO?)
Supposedly, they are made for Excimer/CO2 only....wonder if that is
what saves some $$$. One could quickly do a test to find out without...

I just read an answer on the laser newsgroup....perhaps you can post it here?
It did sound rather involved, but the name of the game is prevention of accumulated gas that could go boom in the...

If it would be of value, we could provide a few things we have learned lately about cooling after using our laser and studying it with the other one.

Being able to read the comments here and...

I have no idea how unusual it is to use liquid cooling in other power supplies. Water has some great and unusual properties, so I am sure that using it in some power supply settings might be in...

I can get away with flaming myself, right?

We were not getting any leads as to pin outs or schematics, so we hauled the laser into a lot more light, and pulled panels off...

We found that the...

Murphy and others have brought up some good specifics as far as actual cooling needed and they have introduced the quantitative aspects of the cooling operation.

Since many formulas show up in...

Thanx
You are right, naturally.
We have been contacting second hand dealers all over (why so many in Florida?!!)

Armed with a new term now, BME, we will be collecting yellow page phone numbers...

While I had the covers off of the 40 watt Coherent surgical laser, we read the specs on the coolant pump.(laser units manufactured in Hull, England, with a Japanese coolant pump no less)

The...

So far, I have received nothing, yet, from the posting to alt.lasers...

I did find one place back east that would sell documentation to me for the Coherent laser, for $200. They said there was...

My sons and I started to combine a cast-off Isel with DeskCNC and a laser for cutting and photo engraving.
We hit a snag with the lasers when we decided to adapt existing surgical lasers instead of...

Thanx
I posted quick pictures of the two in files here.
I will post message as you indicated later today.

I did find one place that had 3 of the flowing gas for sale and a university that...

We were going to build a laser, but found two working surgical CO2 lasers, each with articulated arms. The smaller of the two is Coherent 30 watt with hand piece, and is a sealed beam, with sealed...

I wan't nec. advocating just plugging in a box, but pointing out that all 4 axis, the Power supply and isolation circuits are all together in a small package. It would still be nice to know which...

Isn't DenverCNC putting out a Xylotex based 4 axis controller, rated at about 2.5 amps and 24 volts? It is listed on the DenverCNC web site and also on Tim's K.T. Marketing but neither one goes into...

Jeff said "I don't have any trouble with my Gecko G320's faulting at ALL!!

If you have a large count encoder this could be your problem."

Could you bring me up to speed as to what size motors...

Am pleased to report the end of the pin-out request.
When I posted the picture, I posted the pins I had identified to that point, leaving only a few to figure out.

Erik gave an excellent URL...

thanks for the reference.

I did sort out which was probably the brake....both black, and on top of the motor. I posted that as pins 6 & 4, in the explaination with the diagram, in an earlier...

Well, looks like I inadvertently stumped the wizards again....I put a hand-copy of the wiring pins for that Isel engraver....and cleared up the text a little....in the thread "Pin out help".

I...

OK
here is a quick sketch of the general config. showing dark pins
and clear circles as no pins.
Hopefully, it is easier to envision....we are just not sure how
to hook it up to a controller and...

HI
The plug appears to be a circular plug, with 4 large in the middle
with 11 smaller around outside. A total of 9 are used, but there
are more wires coming from top of motor housing. Some are...

ok
We are in the middle of several projects, but we could use some help on stepper motor wiring...basic stuff, but we are new at this.

We ended up with a used Isel engraver, and we have no...

I've been checking it out as well.
Seems Rutex will be setting up a US dealer soon. It is in the
works and supplies will be from the US of A. The dealer is also
a builder and has experience...

What are the specs on your lead screws and the nuts?
