Lasersaur. Lets never ever ever ever build this.
« on: April 02, 2012, 08:01:31 PM »
Give me a quick rundown, those of you who know what we're dealing with.


What are we looking at as far as cost of parts?
Would this help at all? http://www.thingiverse.com/thing:11653
What size T-slot are we looking at/for when/who can order it?
Can the lab help fund part of this?


Dave Casey, don't you have a lasersaur board?  Lets populate that thing.


The biggest benefit I can see with the lasersaur is thus:
  • We can print out large format objects like the Prusa Air, etc
  • WE CAN HACK IT! (I already suggested a "print feed" alteration where you could load a stack of acrylic in the back and have it auto-cut sets of stuff)
  • A lot of people who want to learn how these things operate, can understand more intimately how to tune them.
  • Redundancy - If our 40w dies, we've got a backup!
I'm pretty much "finished" with my Prusa.  It's only minor tuning from here and making it more user friendly for when I drop it off @ the lab for people to use.  I'd like to start working on a project which will further my engineering capabilities.  We've talked a lot about this already.  It's time to DO it.  I'm willing to coordinate with people to get this done, order the appropriate parts, gather a BOM, etc.  Just need to know who's interested, who can do what, who HAS what already...

I have the "nortd custom parts".  Hybridsix might be able to get us a break on some of the t-slot if we use math to figure out how much we really need. (BOM lists a zillion little pieces.)


The controller board I have is from the LAOS folks.  http://www.laoslaser.org/ It is currently unpopulated, and I haven't gotten around to ordering parts for it yet. (I've been crazy busy lately)


As far as I know, the LAOS board has not been used in a lasersaur yet, but if it doesn't work for us as-is, I am sure the LAOS folks would be happy to help make it happen.

Holy moly.  They want $288 for some laser cut acrylic pieces?!  Surely we can get access to the CAD files?


Also the rest of this...brackets and such?  Wow.  The cost is way out there.  Surely there is a cheaper alternative to a lot of this?

I HAVE the laser cut acrylic pieces. Those are in that big box that says "Lasersaur" on it.  Based on what I paid for 'em, $288 is a bargain. 


Who knows, maybe there is some other stuff in that box too. I guess I should open it and find out, but it says, "open with extreme awesomeness" and I just haven't felt up to it yet.

Matt told me there was a place called ACME surplus down close to me; apparently they sell 2040 extrusion by the pound and very cheaply.  I'm going to pick some up just for shits and giggles really.  I'll try to get some long pieces and we'll see what we can make out of it.  Gotta start somewhere.  The frame would be a nice start.

well, I don't know how cheap it is. I forgot the per-pound price. But it's worth checking out anyway. They have a number of different profiles and sizes. it is all scrap/surplus though, so you might not find everything you need. But ACME is a really cool place anyway so a trip there is never a waste :)

I opened the box.  It said "Handle with awesomeness" not "open with awesomeness".  Not only did it contain the acrylic parts, but it also contained the nuts and bolts, presumably reducing the BOM cost by another $116. (I didn't notice whether or not the t-slot nuts were included in there, if they were, that is another $222 of the BOM taken care of.)

Depending on the profile of the T-slot we get, we might not need specialized T-slot nuts.  I've been told the mitsumi profile actually has the space for standard 3mm(?) nuts so that will reduce the cost a bit as well.  I've gotta get the time to run down to ACME metal surplus and see what kind of tslot they have.


I guess first and foremost is getting the frame put together, right?

Alright, so ThantiK and myself will be busting some ass getting this thing up and running. We're going to run subsystem by subsystem, and just build out the whole thing a little at a time. I'm going to work on a Google Spreadsheet with a BOM.. Most of the parts that they have listed they're getting from one supplier, and it's kinda pricy that way, so we're going to explore alternate sources to make things more reasonable.

We're going to start at the top of the whole thing, the frame gantry, and go from there, in the sequence of assembly, so that we can basically buy it as we build it.

Here's the BOM so everyone can see as we're working on it:
https://docs.google.com/spreadsheet/ccc?key=0Akfb5p719f2-dG9tTUxVVlRhNjRlREFqZFpNMDdkQWc


If anyone would like to help out in the laser area, that'd be cool. We're going to need a power supply and laser tube. I was thinking 100W, since that'd open up more possibilities for us.

Is there a reason the CNC router could not be fitted with a laser?

Well, the laser tube has to be mounted somewhere, mirrors need to be assembled to direct the beam via flying optics, and then you have open-beam that is uncovered.. 100W laser beam without protection would be very dangerous, not to mention that there would be no shielding around the workpiece, at that wattage specular reflections can start fires and blind, since the laser beam is invisible, we can't tell where it is going.

This part of the project is interesting to me.   ::)

What version of the p.c. board?

100W CO2 Laser Source
« Reply #12 on: August 25, 2012, 09:31:27 AM »
Through my connection with Inventors Council I have contact with a prominent laser inventor/manufacturer.  I asked him about 100W lasers and this is his reply.  Seeing I know nothing about this stuff I leave it to you to follow on.
Dave Woods
 
       Yes. We have Carbon Dioxide LASERS already being Built, that are rated for 100 Watts, CW, Output. We have one, Now that does 80 Watts, CW. We just opened up a Larger PLANT, in order to Process the Assemblies. We have the Laser Tubes, Chiller (for the Water cooling), Sealed CO 2 LASER TUBES of 100 Watts (RATED, and Power Supplies for them.         We also have a Unique Construction Plan for them, which is very stable, and self-aligning. and, we have the correct optics to make the Laser Work more Precise, and have NO Astigmatism!  It is a Special Process/SETUP.         We have been "jammed up" with work, and did not see your email until today.    Hopefully, you have not purchased the LASER, yet, as we can Build ones for You that are Very Inexpensive, and attractive Compared to "Other" Company's Products.   Please Advise.   Thank You kindly,  *********************************  LASEROB !!

Very cool Dave! Definitely a key part of this build.

We really need to get an inventory of what we have in da3v's kit, and then start ordering the first 'set' of parts.

I finished (I think) the CAD drawing.. I made things bigger and stuff.
