Do you have one of those china laser or is it from a surgery, too? 0,2mm engraving depth? Thats enough for colour fillings! Cool! But the adjusting process until you got a working laser without becoming blind is probably too difficult (for me). Do you have to readjust the lense when using different aluminium panels with different material thickness? The other thing is... its probably hard to set the same zero point when changing from milling to laser engraving. Do you drill the holes for the switches (the switch at the HF section for example) with a drilling machine? I looks like it was milled?
Hi Frank, around 2001, Sharplan closed one of Israeli branches and
a lot of laser surgery stuff came direct to surplus place 10 km from my house..
think china laser from ebay will work OK...0.2 mm is beam diameter,
it cleanes anodise, not engraving into depth, iirc it called sign marking..
anyway, looks pretty good.
The focuss of laser have to be re-adjusted for different pannels, and
of course when you working with laser use protection glasses.
I use same machine for milling, and it has holes for pannels,
which are standard for 1/2/3/6 etc RU.
To zero machine, use home sensors,
it looks in g-code:
g28
g92 x0 y0
g00 x-500 y50
g92 x0 y0(laser)
(there's magic in this name -G-code!!
)))
I think to build another machine for laser engraving only, and
use "moving mirrors". To get this thing working, you don't need to
adjust all the stuff with co2 laser, just put small red laser at the
same axe for start, adjust mirrors to get the beam correct
on all of machine positions, then after installing c02,
some little corrections needed.
Why is CIn (the red beast) needed with DC-servo present for the input stage ?
Ask George
))) Anyway, it works just fine, see schemo.
where do you buy centertapped alphas? alphastat here in germany doesn´t have them.
???? I have a stock from year go...ask Peter Gross they should to have them. As well, they helped me once with pot which was unavailable from any other place...for me, it is a bit hard to communicate with them, but the service is excellent and potentiometers are very good quality.
