I've written up a guide on setting up the nanoDLP v1.1 shield from Fysetc with an attached Nextion screen. It's pretty straightforward, but not everything is intuitive and the manufacturers documentation is virtually non existent. The biggest gotcha is the fact that the stepper motor driver sense resistors are 1/10th of the value usually used, which means that if the formulae found all over the web for the DRV8825s are used, you will end up overdriving the motor and thus the whole shebang will just shut down

I see lots of these board out there, but without guidance I believe majority does not get deployed.
Your guide looks great, thank you.

Yup, they're not the easiest things to get working with hte lack of documentation, but once you know how, they become very easy to deploy.
I'm now attempting to get one working with an Orange Pi PC 2... that's not going too well, can't get nanoDLP working with the Raspbian image provided - I have a feeling it's to do with the fact that some of the libraries wanted by nanoDLP are specific to the Raspberry Pi, like some BCM related libraries.

Yes you are right it build against BCM.
Try generic ARM builds as it does not require BCM library be available.

Is it possible to get smooth movement of stepper motor with nanoDLP v1.1? I get really nice movement with Ramps 1.4 but if I use nanoDLP v1.1 shield with direct control from RP3 it moves but not smooth.

Right now it is not possible to get smooth movement through direct control.
