need help tuning scanpro20's

[mrblack927]

Hi all!

You're all so helpful I wonder if anyone can help me out with my goal here. Here's the problem; I bought a set of scanpro20's from LSP and set it up. In the manual it says to "match the serial number of the driver with the serial number of the scanner". There's only one problem... they don't match up! I got a kit with 4 different serial numbers. This is unfortunate because the drivers are factory-tuned for the specific scanners they go with. I set it up anyway hoping for the best, and found that at least one of them is outrageously out of tune, so I set out to tune it myself. I'm using the tutorial from the LSP website but I can't seem to adjust anything correctly.

I guess what I'm asking is, is there anyone here who has tuned a set of scanpro's? I've identified the pots on the drivers, but when I turn them, nothing seems to happen. I'm using the ILDA test pattern and looking for undershoot or overshoot to occur as I rotate them but I can't see any decernable change. Am I using the wrong scan angle maybe? How do I change that?

I'm very worried that I'll overturn something and break the scanners, what's the risk of that? Any advice is appreciated.

Thanks!

If LSP means Laser Show Parts, then ask here directly to Dave
If I were you I would not try toset scan, especially when identification serial number are not matching. I think it could be a highly risk attempt.
Better to wait few hour rather than destroy a scanner set..........

Dave.... where are you? there's a job for you.....

Haha thanks, I agree it's better to find out more than to risk the scanners.

I did email LaserShowParts about the error when I first got the kit in the mail, and I believe it was Dave who responded. He basically told me that the items are dropshipped from china and if the serials dont match up then just try both X/Y combinations to see which has the better result.

Unfortunately, the Y axis is simply to skewed... I need to do something.

Hello MrBlack927;

If you post some pictures of what the scanned image looks like, we can probably talk you through the process. (Need to see the ILDA test pattern and the LaserMedia Test pattern.)

I wrote the tutorial that you found on the LSP website. If you're having trouble following it, post your questions here and we'll figure out what the issue is!
