Hello everyone,
I am pretty new to the Reprap scence, this is my first printer. I finally got the thing built but not I am having problems getting the board to communicate with the computer. I am running Windows 7 on a 64 bit machine. I have built a Prusa Mendel model and having a RAMPS 1.4 & Arduino Mega 2560 board for the electronics.
I purchased a LED power supply to power the board and has the required current. When I frist connected the circuit to the computer a LED 01 (right near the USB connection on the RAMPS board) would just continuley flash. After searching the internet for awhile I thought it may be the drivers and the firmware. I downloaded the latest drivers and installed Merlin on the board. In the Arduino software it says it uploaded successfully but now there is no LED flashing on the board.
I have tried checking the BAUD rates and making sure they are both set to 115200. Whenever I try and get RepSnapper to communicate with it just tells me no printer is connected.
Please help me figure this out. If you need more infomation I would be happy to provide it.
