I ran the web configuration tool in newbie mode for firmware 0.91, selecting Megatronics 2.0 with an RRD Graphics LCD and a delta printer config. Since the card isn't hooked up to a printer yet, I left all of the printer measurements and other settings at default.
The resulting firmware compiles clean on Arduino V1.05r2 and uploads without issue to my Megatronics V2.0 clone. The serial monitor shows it rebooting and saying that there is a temperature defect on extruder 0 (not hooked up to anything) and that the printer is in dry run mode with 1130 free RAM. However, sending an M105 or any other command via serial monitor results in a never-ending loop of "Retry:1" messages. In addition, the LCD display is blank, neither piezo buzzer makes a sound of any kind, and I suspect that none of the other items on the LCD card are working.
Is this normal behavior when the board isn't connected to anything? Has anyone tested the web configuration tool with a Megatronics V2.0 setup and had success? Do I still need to edit any config files when using the configuration tool? I can upload the config file(s), if needed.
FWIW, I was able to successfully upload the latest Marlin version and the display and everything worked, so I don't think that it is a hardware problem.....
