Prusa i2: I am trying to get past my first print. Using ABS, I've set the extruder to 230c and the bed to 110. When pronterface tells me it;s up to temp, I try textrudede a bit, and I get bout 5mm and it spins, but no more ABS is taken up. I have tightened the door as tight as I can get it. I suspect the hot endjustjsut not getting hot enough.crankedmked the temp up to 340 just to test, bby charlieRC - Reprappers
Ok, never mind. Found that the thermistor was plugged into the wrong header.by charlieRC - Reprappers
Any idea what could cause the heat bed not to come on. no power from the rambo but not sure why. The hot end (and everything else) seems to work fine. I have a 10k thermistor on the bed. Is there someplace else I need to be configuring this? ,,,from configuration.h ... #define TEMP_SENSOR_0 1 #define TEMP_SENSOR_1 0 #define TEMP_SENSOR_2 0 #define TEMP_SENSOR_BED 4by charlieRC - Reprappers
My heat bed is not heating up. No power is going to the bed. The hot end works fine, but I must have something wrong in the settings for the heat bed. Can someone give me some ideas of things I can look at. Right now, I have TEMP_SENSOR_BED set to 4, the 10k bed thermistor plugged into T3 on the Rambo board, the bed heater is plugged into HEAT2-BED. In Pronterface, I have the bed set to 11by charlieRC - General Mendel Topics

Does anyone know a part number for the fuses on the UltiMachine Rambo board? My F2 fuse seems to be blown, but not sure where to find replacements. Thanks. Charlieby charlieRC - Reprappers
I don't know how to tell if my rambo board is any good or not. I don't seem to get any motion from the moters, or heat from the extruder or bed. No LEDs light except those associated with the processor. Unfortunately, I am new to this and don't really know what the next step is. Can anyone PLEASE help?
