Build Your Own SLA/SLS

I don't think the focus issue is solved by moving the lens out but by moving it down (edit: put up at first). I'll give it a try tomorrow. Also how'd your sensor work out?

Has anyone successfully opened the 6510? I tried for a few minutes but didn't feel like breaking it....

Looks pretty good!

That looks like the problem is the post above yours, ie computer turning the screens off. Happened to me on my first print, CW keeps the layer cycles going but the project just shows the acer logo. Then at some point you woke it up to check progress and it turned the projector back on.

I made a pretty detailed tutorial that can be found here viewtopic.php?f=5&t=3684

Not an arduino master and haven't use the while command before but I think this should do it...

It should show the reading until you press the "R" button again. I repeat should...

Looks great. Always nice to hear about people building their own instead of buying!

I'd like to request that the machine profile and slicing profile in use be added as variables when slicing. I have visions of putting my projector on a motorized axis and having it automatically goto the right position for the xy resolution based on the machine profile selected

If you use Marlin you can find the pin assignments in the pins.h file https://github.com/MarlinFirmware/Marlin/blob/Release/Marlin/pins.h This file has the pin assignments for all the different types of boards so you need to find the Arduino Mega. Having a quick look I found: #define Z_STEP_PIN 46 #...

Looks great!
