Basically, I cannot get past uploading firmware step, because LCD panel inputs are not working properly, so I am suspecting something is wrong with the firmware.
I hooked-up all the wiring to RAMBO, powered it on, and everything seemed OK (got 2 horizontal bars on LCD). Afterwards, I've installed windows drivers (using 8.1 64-bit), downloaded Arduino IDE 1.05, selected correct board and COM port, and performed EEPROM_clear operation (worked perfectly). Then, I've downloaded the V2 sketch, compiled and uploaded it to the printer (there were many compilation warnings, but the sketch was uploaded to the machine). Is this normal to have dozens of warnings when uploading the sketch?
Afterwards, the RAMBO restarted and took me to the default screen, which looked perfectly. There were temp readings for the thermistors, and the status said "OK." However, when I try to turn the knob, instead of navigating the menu, it just momentarily displays gibberish characters on the top line of LCD . When I click the knob, it does take me to the menu screen, but again it displays gibberish on the top line when I try to turn the knob left or right.
The 'Reset' button also does nothing, and there is no movement whatsoever from the stepper motors.
Also, MatterControl cannot seem to connect the printer either (went through all the steps, but it is perpetually stuck while saying 'Connecting'). The yellow light is continuously blinking on the RAMBO when the PC is on. Restarted both the PC and RAMBO several times to no avail.
I hooked-up all the wiring according to the guide, so am not sure what the issue might be. The only problem that I've encountered was that the bridge between LCD panel and RAMBO board (the one where ribbon cables plug into) had some of the pins bent slightly (it was packaged too tightly against the plastic LCD box), however, I've straightened them out with needle-nose pliers and there did not appear to be any damage to the connectors.
I would really appreciate it if you can point me into the right direction to fix this issue (very eager to start printing!). Thank you very much!
p.s. I tired to upload images of the LCD screen error, but the forum errors out when I do that
