Farbeinstellung von Kristall mit Pango Intro QM32

[flo]

Hallo!!

Habe gerade das erste Mal meine Version von Pangolin mit Farblaser und 8 KAnal PCAOM getestet.

Jedoch hab ich Mühe mit dem Blau!! Liegt das an dem, das PAngolin nur 6 Kanäle ansteuert und somit den 7 und 8. Kanal beim Kristall nicht ansteuert? (Ich gehe übrigens vom QM32 nur mit RGB raus)

Oder habe ich den falschen Pin an der Karte angeschlossen? Denn es soll ja 2 Blau von der QM 32 geben. Ich habe natürlich das "brightest blue" genommen, und darum kann ich mir nicht vorstellen, dass ich den dunklen Blauton nehmen sollte.

Desweietern nützt es gar nichts, wenn ich in den Farbeinstellungen von LD die Farben auf andere Kanäle setze.

Tja, ausser das Blau hab ich sonst alle brilliant drin.

Vielen Dank für die Infos

Hi flo,

I can see that there is some confusion here. Yes, it is true that common PCAOM drivers have 8 channels, and yes it is true that Pangolon "only" has 6 channels, but let me assure you that this is a workable situation.

Typically, the red wavelengths are very close to eachother and are indistinguishable. So for example if you have 647nm and 676nm, your eye can not perceive a difference in the color, only in the brightness. Likewise, multiple green wavelenths also look the same to your eye.

If your PCAOM is set up for the following wavelengths:
676nm RED
647nm RED
560nm YELLOW
530nm GREEN
514nm GREEN
488nm CYAN
476nm BLUE
457nm DEEP BLUE

Drive both 676nm and 647nm RED with QM2000 channel 1
Drive the 530nm, 514nm and any other greens with QM2000 channel 2
Drive the 476nm BLUE with QM2000 channel 3
Drive the 457nm DEEP BLUE with QM2000 channel 4
Drive the 560nm YELLOW with QM2000 channel 5
Drive the 488nm CYAN with QM2000 channel 6

In any case, the idea is "strapping". You "strap" certain inputs of the PCAOM driver together and drive the "strapped" channels with a single QM2000 channel. This is a very common technique.

I believe that there is more information within the QM2000 help file.

Hello William

First, thanks for your fast support...)

Second, now you mean, i should connect both blue wires into one to get the reached blue..

My ILDA Test pattern for colors seems to be okay, exept the blue looks very pink. There is red inside... too much red.. I use a crystal technologies crystal and a ALC 909TLC Whitelight laser.

Dont forget, i use QM32 not LD2000.. but i think the pins are the same like QM32.

The main question now is: How can i get out the blue color..?? Should i now wire both blue lines from QM32 into one? I actually use only RGB to control the PCAOM.

Thanks and greetings from switzerland!!!

Hello Flo,

OK, there is a slight difference. The QM2000 uses an ILDA allocation of colors by default. (Of course the QM2000 and QM32 can use any color on any channel, but there are default assumptions).

In any case, no matter what QM you have, all have 6 channel output. (At one point in time, LD Intro and Basic only had 3 channel output, but that restriction disappeared many years ago.)

The thing to keep in mind here is that ideally, you want each wavelength THAT IS VISIBLY DIFFERENT to have its own drive from the QM board. You can strap colors that look similar, like reds and greens, but each shade of blue should get its own line.

As to the reason why your blue looks pink, I believe that this is probably caused by the color system not being trained properly. Training is unique to Pangolin products and so it is often misunderstood. However, it is very well documented. I recommend that you take a look at the "color" section of the LD help file.
