I have a Raspberry Pi 3B with a NanoDLP Shield 1.1. I have gotten NanoDLP running and Nextion screen working but the Z-axis wont move, from the screen or from browser. I've confirmed the motor is good (actually tried 2, both good). I checked the ports on my pi and got this list:
/dev/tty /dev/tty19 /dev/tty3 /dev/tty40 /dev/tty51 /dev/tty62
/dev/tty0 /dev/tty2 /dev/tty30 /dev/tty41 /dev/tty52 /dev/tty63
/dev/tty1 /dev/tty20 /dev/tty31 /dev/tty42 /dev/tty53 /dev/tty7
/dev/tty10 /dev/tty21 /dev/tty32 /dev/tty43 /dev/tty54 /dev/tty8
/dev/tty11 /dev/tty22 /dev/tty33 /dev/tty44 /dev/tty55 /dev/tty9
/dev/tty12 /dev/tty23 /dev/tty34 /dev/tty45 /dev/tty56 /dev/ttyAMA0
/dev/tty13 /dev/tty24 /dev/tty35 /dev/tty46 /dev/tty57 /dev/ttyprintk
/dev/tty14 /dev/tty25 /dev/tty36 /dev/tty47 /dev/tty58 /dev/ttyS0
/dev/tty15 /dev/tty26 /dev/tty37 /dev/tty48 /dev/tty59
/dev/tty16 /dev/tty27 /dev/tty38 /dev/tty49 /dev/tty6
/dev/tty17 /dev/tty28 /dev/tty39 /dev/tty5 /dev/tty60
/dev/tty18 /dev/tty29 /dev/tty4 /dev/tty50 /dev/tty61
ttyS0 doesn't work and ttyAMA0 is the port for the Nextion screen so I set the Ramps USB/Serial Port Address to ttyprintk. It allows me to do this but neihter z-axis control nor the touchscreen move the motor. Any thoughts on what I may be doing wrong?

I think you might have the ports flip-flopped.
How is your Nextion connected? If its through the conventional GPIO pins 15 & 16, it should be on /dev/ttyS0. Have a look at the sticky for connection Nextion in the Tips & Tricks pages
if you leave your printer disconnected, what is the output of 'lsusb' ?
the 3B+, the physical ports are ganged togther. you will only see 1 USB port to show up if you ls /dev, I am pretty sure it is the root USB of the hub.
( see https://github.com/mvp/uhubctl#raspberry-pi-b2b3b)
for me, its /dev/ttyAMA0 and /dev/ttyS0 which is the Nextion
for my setup - with 3B+, lsusb yields

Thank you! Turns out I was looking in completely the wrong place... using the NanoDLP Shield 1.1 (not sure about 2.0) i had to access it via gpio, not serial. If anyone else runs into this issue here are the key gpio ports on the 1.1:
Step: 25
Dir: 23
Limit Top: 18
Limit Bottom: 24
PWM: 17
UV LED (Shutter): 5

Please accept my apologies- I missed that you were using the sheild.
Its great that you got it worked out.
Can you post a screenshot or two of your config settings pages? That might help people to see where they have to enter this info.
