I have everything I need to give it a go now. When do you think the next release for LaserShark support will be?

Thanks for the updates PacManFan!

Here are my test results with manually previewing the first layer with all the latest updates.

Thanks a lot!

Here are the fist layer of the print and the actual display image on a paper(by DSLR long exposure).
You can see there are some laser lines on the blank area which is strong enough to cure the resin in you put the vat too close to the laser. So i put the vat far away enough to have a better fist layer.

Excellent results!
Can you display more than 3 or so slices? I want to know if I fixed that bug.
The layer display time in this should be a constant time based on the number of pixels scanned. The next algorithm is going to skip over spans of unlit pixels in the image, this will make the individual slices faster based on the per-scanline model slice geometry. Do you think you can perform a build of a model?

Hello all

This is my first testrun with the new lasershark plugin for CW.
It's look really good now and it begin to work :P
Now i need to make frame and connect stepper motors to print some models.
Here a movie what i have tested.

So far so good! Looks like curing takes a little more then one scan on my setup at .1. I'm currently running at .05 a layer which seems to help, but may go to .02 just to get more exposure time.

Also focusing the laser looks to be a fun job! :)

This is were I'm at so far:

Here is the latest 1.0.0.5 version of the Laser SLA plugin. Replace this with the one in your CW directory. Look for your existing 'LaserSLA.cfg' file and delete it so it will be re-created. Inside, there is a 'pixrepeat' variable. This variable determines the number of samples that lit pixel will be shown for a longer exposure time. Currently, it's set to 1, you can set it to any value (try 2-5), this will make each lit pixel be exposed for X amount of times longer. You can also change the laser galvo rate in this config file. The default is set to 20kpps, your setup may support higher speeds.



Thanks to all who've posted your results, I really didn't expect someone to make a complete build at this point.
