Ultimaker v1.5.7 with arduino mega firmware help

Recommended Posts

Hey guys, i have a problem with connecting my printer to pc. I have downloaded the repetier host software and arduino software. Then i got marlin firmware for my boards and tried uploading it, then i get errors about codes being void. I think the firmware might be corrupted. I did get a firmware that loaded onto the board, and activated the lcd display, but when its uploaded the lcd screen is blank and when i do manual control on the printer via repetier host there is no output/movement on the motors. I just have two red led's glowing.

Can you guys assist me to start the firmware loading from fresh?

And where can i get legit firmware for my boards
