nanoDLP

Hello Shahin,

I'm recently making a DLP printer with Nanodlp. The Nanodlp is successfully installed on Nanodlp and connected to wifi, and I used ramps with Marlin-mUVe1DLP-Running as firmware. The z-axis could be controlled, and I can see Gcode commands on terminal. However, when I tried to change some setting (such as enable LCD display, change Ramps port address) and click submit, nothing could be changed and the Nanodlp page will show "value must be larger or equal to 1". I tried to update Nanodlp and firmware, but still nothing changed. Now I'm struggling. To let you understand my issue, I'll illustrate how did I install Nanodlp:

·Download Raspbian Lite image file and wrote to RSPi 3.
·Connect Pi 3  to internet, copy the link on Nanodlp website to download Nanodlp.
·Download Marlin-mUVe1DLP-Running from website, and flash it into Ramps. Note that I've tested Marlin and Grbl with Nanodlp, they work well but they don't have tilt control, so I can only choose Marlin-nUVe firmware.
·Connect Ramps to my Pi. and click "connect" button on Nanodlp page. It's connected.

Then my issue comes. I can't change anything on Setup page. Whatever I changed and submitted, it will show "Value must be larger or equal to 1". Could you help me solve this problem?

Thank you!
Johnny
