Garbled Terminal

I am running NanoDLP on a Windows ultrabook.
I have an Arduino Mega w/ Ramps using Marlin 1.1.
I run nanodlp and access it via http://127.0.0.1:8080.
Then I go to setup and select 'COM3', leaving everything else at default.
When I go to Terminal, I get this:

Eventually I also get the error "Could Not Write to Status JSON File public/status.json open public/status.json: Access is denied."

?

Re: Garbled Terminal

The usual issue when getting a garbled response from and Arduino/ Ramps set up is the baud rate is incorrect
The baudrate is set in the Marlin configuration.h file  ( default is 250000)
PS there have been some comms issues with the latest Marlin 1.1.x  so you may also want to try older versions and see if that helps
Good luck

Re: Garbled Terminal

bigfilsing,
Thank you for your advice!
I went back to Marlin 1.0 and changed the baud rate to 115200 and now it communicates properly! Thank you.

On my printer, I only have a Z axis stepping motor (Nema 17 from Openbuilds) and two end stops at the top/bottom of the z-axis. I use GCode to turn on/off the projector lamp. Basically a Kudo Titan type printer.
I am not sure which board to choose. I am currently getting errors about temperatures heat bed etc, which I do not have.
