LittleRP and Raspberry Pi 3

Hi all,

Is it possible to upgrade my LittleRP with Raspberry Pi 3 to be able to use nanodlp software?

I run my LittleRP with a Raspberry Pi 3 and the Photonic3D software (previously known as Creation Workshop Host). Version 1.0.0 worked fine; the current version 1.0.5 isn't working for some reason I haven't figured out yet. But the problem is in software somewhere, not in the LittleRP. It didn't work well with an original Raspberry Pi; it needs the additional processing power of the later versions.

I haven't tried NanoDLP software but it should work fine as well. I'm intrigued by its ability to directly talk to the stepper driver. I currently run the printer through a RAMPS board, and it would be nice to control directly instead and eliminate one circuit board and one cable from the back of my printer.

I really appreciate how I no longer have to worry about ruined prints from screensaver turning on, my wife switching to her account on the computer, accidentally opening or dragging a window onto the projector's screen, etc. Main difficulty I have currently is lack of a z homing switch. Manually homing the build platform when the printer isn't right next to the computer is not convenient. Currently I use a small tablet so that I can stand at the printer while homing, but the buttons on the screen are small and I've accidentally lowered the platform 10mm when I meant 1mm, causing it to stretch out my flexvat's bottom. (Happily it didn't break!) Any day now I'm going to make a z endstop holder for the LittleRP.
