Hi Guys. I have a scanner output of upside down pattern. and wording. X and X input look right but? Thanks John H

Turn projector over?

Seriously not sure what your asking, but you just need to swap invert the +/- signal. You can use speaker polarity switches or rewire, possibly your scanner amps have jumpers also.

Hi. I will try switching the + and - around. I have never seen this before. (I could mount projector upside down to get right) Ha Ha. Thanks John H

Just to be be clear I am referring to the +/- of the Y or X signal coming in on the ILDA plug. think on pin 1 and 14, or 2 and 15. Don;t have a plug in front of me but wanted to be sure you knew i wasn;t talking power of any sort.

For a "quick fix", you can also invert the individual axis in your laser software (at least I know you can do that in the Pangolin software suites), and use that to determine whether the X or Y axis is actually the culprit...

I see different things from different DAC manufacturers. What is up for some is down for others. So, just fix it in software or change the X/Y pins at the scanner. No biggie.

Hi Thanks for the input. I did change the X - & + around then Y - & + aound to the scanner only, so now the pattern is right. Looks good now. CHEERS John H
