LaserShark Support / Re: Adjusting output size with Openlase

« on: March 25, 2017, 02:21:43 PM »

Great thank you!

edit: looks like I already had those connected. Is there a specific order I should be running the programs to get them to work? Maybe I'm just not using the output app correctly.

edit pt2: I just had to eliminate the jack connection from playidla to lasershark. Works now.

LaserShark Support / Adjusting output size with Openlase

Hello,

How do I go about using the output application to change the size of my playilda output? Not sure when to run it.

Thanks,

Thanks for the informative reply.

The X and Y lines have three wires each.

Perhaps the issue is tuning. Do you have a link to any good tutorials? I have watched videos explaining the tuning process for the ILDA pattern, but I've been hesitant to touch the pots.

Do you recommend tuning exclusively to the ILDA pattern? Or would it be beneficial to tune to what I want to display (since I just need a static image).

I understand that they might be over advertised. However, even when running the idla test pattern at lower (ie half the rated speed) speeds the distortion is present. I can't really imagine that they would overstate to that extreme, but perhaps.

I have also noticed that the noise is only produced by the Y galvo. Swapping the X and Y outputs on the lasershark confirms this. I did sort of fudge the soldering job on the Y connection (overheated the pads a bit) but it still seems ok. Is there any way I could diagnose whether its an issue with a physical connection?

LaserShark Support / Galvo distortion with Lasershark

« on: March 15, 2017, 01:13:36 PM »

Hello,

I am having distortion issues with my scanner system. The distortion is most pronounced at higher scan speeds. The distortion is also accompanied by odd noises from the galvos, which sort of resembles a repeated scraping sound. The galvos are from Spacelas, and I have been in contact with their representatives. After sharing pictures and videos with them, they sent me this email:

"Hello ---
 
There are too much points for output, you need to cut the some lines by using a DAC card.
 
It is no problem of the galvo set yet."

If anyone has encountered such a problem and can shed some light, please do. I was prepared to simply get another scanner system but they insist it's not an issue with their hardware.

Thank you,

LaserShark Support / Openlase with Lasershark

Hello,

I'm wondering what the correct way to go about using playilda from openlase with lasershark is. I've set everything up with JACK and made the output/input connections for playilda as well. I'm just not sure what to run to get the lasershark sending data to my scanners. Using Ubuntu.

Thank you!

LaserShark Discussion / lasershark_display_image

The scanner appears to move horizontally very quickly, and vertically very slowly. Not sure how to get the image I want.

Some questions:

1. Does _displayimage rely on ttl modulation to draw images?
2. What parameter should I change in _displayimage to make the galvo angle range smaller? In other words I want to limit the DAC output to something like 1000-3000 instead of 0-4095. 3. Is there software for displaying .ild with Lasershark?
