Hi! I've been recently building a 3D printer and I'm having issues testing it.
This is my hardware:
Ramps1.4
Arduino mega2560
4x Pololu Motor shields a4988
1x Nema17 extruder
2x floppy stepper motor
1x DVD stepper motor
Generic hotend with 0,4 nozzle
Then I assembled everything and I started testing... I tried ramps test code and it didn't work (motors did not move, but I'm sure they are ok), then I tried using marlin and pronterface; it showed hotend temperature stuck at 150 degrees, but the hotend was not hot. Moreover motors would not move.
I also tried repetier host and it returned me a m999 error without any further explanation.
I had no problem installing firmwares on the arduino and the fan of the hotend is working. I also tried changing baud rate but it seemed not to work.
I need a quick help since this is a school project I need to have a working printer before next week (13 days max). I'm asking for a fast solution to this problem.
Thank you in advance and sorry for my bad English.
3d printer test issues (m999 and more) need help quickly!

1)The firmware issue,maybe your thermistor is not the same type as the firmware.
2)The socket of your extruder's thermistor was broken somehow,you can plug one jumper cap to it then check the display of your LCD(it should be 358 degree or maxtemp).
