Printer won't work ? Pronterfac Error ?

Hi,

I have a problem with getting my Printer to work. I build a Prusa i3 and I have a 650W PC Power Supply attached to a RAMPS 1.3 Board. The Power Supply puts out 18 A on 12 V and i think it's enough for the whole thing. I have one extruder attached, one Heatbed and 5 Nema 17 Steppers (1 Extruder, 2 Z, 1 X and 1 Y. I can set power to the board and i can connect to the board with pronterface. After Connection it puts out that the "Printer holds because of Errors. Fix the Errors, than restart the Printer". He is also saying that Max Temperature measured at the Extruder, but i am having the Thermistor attached in the right way and there is no warming up or heat on the printer as well.


Does anybody have an idea to this ?


Thanks in Advance

Daniel

I'm far from being an expert but to me it sounds like you may have your maxtemp set wrong in your firmware. This code posted here is part of my configuration.h file from my Marlin firmware. It seems to me that you may have it set somehow as your mintemp maybe? I got that same error you did only when I didn't have a thermistor plugged in and the error was mintemp, not maxtemp. This is one thing I would look at if I were you unless you already have. Hope this helps!

// When temperature exceeds max temp, your heater will be switched off.
// This feature exists to protect your hotend from overheating accidentally, but *NOT* from thermistor short/failure!
// You should use MINTEMP for thermistor short/failure protection.
#define HEATER_0_MAXTEMP 275
#define HEATER_1_MAXTEMP 275
#define HEATER_2_MAXTEMP 275

This is why I eliminated the "wait for temperature" hold procedure where it looks for the temperature to sit within a 1 degree of 3 degree C window before starting. Saves me hours a day on starts.

It is possible your XYZ is jammed against the endstop. Move them to the center manually.

After that check for short circuits.
