I'm from Brazil. I would pay $40 for shipping! I read in a forum that LRFZ44N mosfet is a good equivalent (is easier to find here). Do you think it will work? LRFZ44N Datasheet Thanks for the help!by MatheusBrum - RAMPS Electronics
Hello, Accidentally both heater wires touched the aluminium block and now the extruder isn't heating. The red led lights up very fast, when i send the command to turn on the extruder, and it turns off again. Every motors and the thermistor are working fine. Anybody knows if there is a way to save the board?by MatheusBrum - RAMPS Electronics

Hello, When power up my Ramps 1.4 (using Sprinter firmware), the arduino became very hot and starts shutting down. Currently Ramps don't turn on (the red led isn't lighting). However, when using the test code it turn on! (I get the leds lighting, but no any movement) Some pics:by MatheusBrum - RAMPS Electronics
