    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.

    Did you set up all the configuration file for your board or just drop in the latest marlin? What did you get the firmware

    I used preconfigured firmwares... was it a wrong idea?

    well if it is preconfigured correctly its fine but you may need to make adjustments to the configuration file. What version and where did you download the firmware.

    If your following a tutorial have you tried to ask the authors?
    I usually start with base Marlin
    https://github.com/MarlinFirmware/Marlin

    I would go one revision back from RC8 and use RC7 though as I have heard RC8 is buggy
    https://github.com/MarlinFirmware/Marlin/releases/tag/1.1.0-RC7

    Then open the configuration.h folder and read through it, setup the option on however your printer is configured.

    Sounds good. I may be unavailable later but if you have a question I will try to respond. The tutorials should have most of the info you need.
