ok could someone post some links or pics of beam table setups (mine will be RG or RGV)

I think a lot of us think of "beam tables", at least for our particular interests, as something like the "Mobolazer" type projectors, as seen here:
http://www.onestoplasershop.com/specials.htm
You often see them as a longer (sometimes open) projectors with multiple mirror mounts for fixed-diameter "chase" beam effects and some (generally) lower-resolution graphics.
A scanner-based multi-color projector like you (and most of us on the forum) have been talking about building can do multiple, 3D beam effects and higher resolution graphics without any external hardware. You could use it in conjunction with bounce mirrors to create many of the same effects as a Mobolazer-type beam table setup, plus a whole lot more!

no, im looking for pics of how people setup their combining optics and lasers and galvos
Gotcha!
I'm attaching a MS Word document that depicts a typical RGB layout (substitute the violet for blue if you decide to go that route), along with the ILDA wiring diagram.
Also, here is a link to a GREAT tutorial & discussion concerning the details of the alignment process:

nice thanks...
i appreciate all the help...
I have my own skills to add to the mix, promise

No problem - most folks on this forum are EXTREMELY helpful!!
I had a LOT of help over the last 1 1/2 years, and I'm just passing on some of the tips I learned along the way.
As was mentioned earlier - if you can make it to any of the SELEM or FLEM meets, you'll be guaranteed to get your money's worth! They're a great learning experience, and a whole lot of fun!!

Hi Keeperx
i have just posted on another thread my optics setup and ... personaly after trying all the other methods i find this the best .... and easyist
to save you time i will copy it here ( so sorry all for the duplicate post )
if anyone has an easier way please tell me
think i might have mentioned this a few times before
But the way that i have laid out my projector optics totaly eliminates any adjustment of the laser heads .... the laser emmision does not have to be at the same hight... infact on mine there is about 8 mm total difference in hight between the beams of the three heads ...
so no floating tables ... no shims ... the lasers can even be at slight angles to each other no no need for perfect drilling ......
the correction of hight is done by mirrors A and B
these also align the beams onto the center of the green laser beam
( nearfield correction )
then the Dicros C and D keep the beams parallel ..... ( farfield correction )
after using this method i would not do it any other way it takes seconds to get perfect alignment
all the best ... Karl
i have percision mounts that will work for a and b, where can i get a set of c and d?
BTW i like that method and will be using it..
and could i replace a and b with a couple of these instead

should have same effect right?

sorry Keeperx
i dont think they will ... the one you linked 2 are platforms and dont have the same multiaxis fine adjustment
the ones im using on C and D are standard MM1 mounts from laserwave although my dichros came from medialas ..... and are rectangular ... so i have just super glued them to the edge of the mount
all the best .... Karl
ahh i see that...
this guy gives me hope..
