Build Your Own SLA/SLS

I had just a question? What is required for turning the projector on and off? Should I use a Max3232 chip? I also couldn't find which pins are used for projector.

Hi,
it looks like a nice piece of software. I haven't been able to try it yet though. I'm using a Trinamic stepper driver for which i'm writing my own firmware.
Is there a possibility to implement a function to send custom serial commands (Ascii or binary) instead of directly controlling the driver?

I really like the function of masking parts of the area while printing! Also waiting for a premultiplied mask to correct exposure issues

Cheers^^

from what i read, you put a lot of thought into the programming. Would it be possible to just use a USB-Serial Converter to support sending serial commands if the PI internal UART sucks? Probably it could be used to further expand support for GCODE Devices, maybe?

Can you give me more details on how to control the projector? whatever I do my projector won't turn on. I should turn it on manually.
