maybe its to large so the scanners miss corners off

But that effect I mentioned works perfectly when there is no blanking at all on it. It just seams to be blanking the wrong effects some times.

there is something very wrong with that video.

at first i thought the blanking was not working, then i noticed breaks on some animations???

strange???

Yeah, thats what I thought first time I tried it but then it changed in some animations. Some of them look like its blanking the wrong parts...

Haven't tried the other two connectors yet, they are connected to the same place in a very similar way. But even my dad, who's an electrical engineer, said the one its on now is logical.

Just spitballing here... But it sort of looks like RGY blanking and the way it's connected, it's only blanking one color channel... Isn't there a master blanking output?

Interesting idea.

Not sure about a master output no, there are three different TTL connectors on the board though. It's just a case of which one.

I bet that's what it is.. You're seeing a color change on one channel as blanking.. If there are three outputs, it would make sense that one is a master blanking output when RG=00. The other two outputs would be discrete channel blanking. That seems logical to me.. Which output is your laser hooked to now?

R G
0 0 = blank
0 1 = green
1 0 = red
1 1 = yellow

no, because if you watch its drawing what looks like blanking lines. even if it is suppose to blanking RGB the red should not be on drawing blanking lines

But... some lines look like they're blanked when they should be color changes.  I'm still betting that changing the connector to the right output will fix it.

I'm not sure with these new fangled projectors but in the old days I think we had a separate output for a blanking galvo and then three separate outputs for RGB color selection (we used an AOTF).

im not saying it wont help. but it looks like its drawing blanking lines.

and red or any colour it should not be drawing blanking lines.

can we get any good close up pics of the dmx board?

Close but it has mostly fixed it!

I connected it to each different connecter one by one seeing what the effect does. The middle one, not sure what it was has done the trick... almost.

The connector it was on before... god knows what that was, the middle one works perfectly for most effects and the same for the last one. It seams it wants more than 1 laser.

this could be a problem if you cant tell it you only have single colour.

with a DAC for example you tell it what laser/coloours you have, 1,2 or 3

Ok worked it out now, I have two connectors. One for green and one for red, the third one has the words 'reverse' on them so I am not sure what that one does. But if I plug a laser into the TTL connectors the shapes are perfect in two different colors.
