Build Your Own SLA/SLS

Hi Guys Little update about focus point of the laser. Oke i can change the focus point of my laser module when you lose the part with the 2 holes, behind it is a lens when you turn the lens counter clockwise the beam will focus more to the module when you do it clockwise it go further away from the...

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: http://youtu.be/cv5_8GxU0d...

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...

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 b...

This is my test video. You can see the laser turned on at the right time. I connected the laser at channel C. But after the first layer, the galvo will not move any more until i reboot the PC and run the CW again. https://www.youtube.com/watch?v=tluyoWnEqNs This is the first layer of the cured resin...

Looks like the 'c' output has voltage along with 'a' and 'b'. It's shutting the laser off, but will not activate it. Tried it on all connections with the laser turning off. Once I remove the connections the laser turns on. Alright, I'm going to double check my code against the MacPod code and make ...

Hi PacManFan,

I am going to buy a lasershark board to build a laser SLA. Will lasershark and stepper motors be controlled by RAMPS or it required the twosteps board as well?
Thanks.
