Hello everybody, I’m new here. Recently, I bought this DLT-600 printer from HE3D. Was able to assemble and wire it together, even with the silly instructions included with the printer.

At first, it would not heat up, the LCD display would show “DEF” instead of temperature reading, and the temperature would always stay at 0% of target. In Repetier_host, I was able to manually send M303 command to the printer and it would work normally just fine. So, I figured, maybe the configuration file doesn’t like the thermistor settings in it. So, I uploaded the configuration.h file to the repetier online configuration tool, “fixed” the problem, downloaded it back, compiled and loaded it to the Arduino Mega 2560 board, and boom!!! The LCD screen now is blank, printer is unresponsive, no command works :frowning:

Now, I’m trying to load the original repetier firmware that came with the printer, and it would not compile, saying that there twi.c is missing, even though, I can see it in the specified directory. Please help!
