Build Your Own SLA/SLS

Hi All,

I desparate need your help, i got PJD7820HD as recommended projector but i have issue with the focus on the upper and side parts of the build plate how can i fix that?

Thanks

This is the same projector as the P1500 / H6510BD and they have similar problems. There are some users who have said that shifting the optics helps.

Hi on which hole should I put it ? And the projector "eye" should be reflected right in the middle of the mirror?

the furthest away of the 4 holes will help with focus. here is a thread on the focus issues I mentioned:
