Nice work! I'd love to see a video of it in action.

Re: DVD reader is a SLA printer
Very impressive! I see that they are using a CD as a first-surface mirror.

Re: DVD reader is a SLA printer
tx u all.
the video can be seen on the FB page.
actually, the miror is a hdd and not a cd. optical miror are expensive and hard to find.... while a old hdd... there are tons around u ! the quality is fine and I see no difference with optical miror for printing. (I'd tested both).

Re: DVD reader is a SLA printer
For the French readers or Google Translate users, you could see my website which was severely updated today, with infos on the control board and V2 printer pages.
Enjoy.
Enjoy.

Print of the day:
25mm high with 50µm / layer (max resolution limit of the DVD reader).

Re: DVD reader is a SLA printer
I'am following this project and I have tested a dvd with a controller board toshiba TB6560 but I don't find the number of the steps for a right positioning of the plate. I have set the controller at half step, current 20%, voltage between 5v and 12v, steps between 9 and 9,15 (I need the right number). I use grbl firmware and to move the plate Universal-G-Code-Sender.

Re: DVD reader is a SLA printer
dvd's steppers are pretty standard try 20 steps
dvd motor spec ( resonably standard )
pl15s020.pdf https://github.com/taksan/Arduino-Lab/b ... 15S020.pdf
the problem you will have is that the tb6560 , suit 1.8 deg steppers , where dvd steppers are 18 deg per step
so they probably will not be optimum .
you'll find full step is better for these drives , however i do not think the tb6560 goes to full step , i think the lowest is half step
so probably a basic L298 Circuit may be better , i dont know .
