	Hi, when I compile in release it works without any problem. When I switch to debug I receive the following messages: Compiling debug version of 'Marlin' for 'Arduino Mega w/ ATmega2560 (Mega 2560)' Marlin_main.cpp:536:2: error: 'MicroDebug' does not name a type Marlin_main.cpp:536:30: error: 'MicroDebug' does not name a type Marlin_main.cpp:536:69: error: 'MicroDebug' does not name a type Marlin_main.cpp:536:116: error: expected constructor, destructor, or type conversion before '(' token Marlin_main.cpp:536:125: error: expected constructor, destructor, or type conversion before '(' token Marlin_main.cpp:536:130: error: 'MicroDebug' does not name a type Error compiling Does anyone know why this happens?

	Hi, A few questions 1) Does your sketch code redefine the standard Arduino Serial object? So can you compile Serial.println("Hello world") in your sketch? 2) What breakpoints have you set? and where? Thanks

	I put breakpoints both in setup and loop. I have to say that I'm trying to debug a 3D printer firmware to understand how it works. So it's not really clear to me what happens and where it happens. Serial is not defined in my sketch, I would guess that is because there's a lcd and most likely the serial connection is used there. (It's also the first time I get in touch with arduino, so I might say something wrong)

	The debugger uses Serial by default. If you sketch re-defines the Arduino Serial then it will not work. Please answer question... Can you compile your sketch with Serial.println("Hello world") It's just test code that you need to add to the setup or loop to see if it compiles ????

	When I said that it is not defined I was meaning that Serial.whatever doesn't compile. So the answer is no: Serial.println("Hello world") doesn't compile. I understand that the debugger needs the serial to communicate, can't I redirect it somewhere else or use the class serial defined in the sketch?

	Hi, Thanks that is clear now. I guess the Arduino hardwareSerial class has been dumped so I guess that also makes it impossible to use Serial2 or Serial3 (which the 2560 has). You can try SoftwareSerial but it depends on how much free space you have on the 2560. It will need 3k or so. Normally projects that re-define Serial are BIG and clever projects that take a lot of cpu space. To use SoftwareSerial you will need a couple of spare digital pins and something like an FTDI cable or adapter. There is a doc here. http://www.visualmicro.com/page/User-Guide.aspx?doc=Debugging-With-Different-Por... Hope that helps.
