    Ok thanks i just wired the z steppers up and it works but the steps are alot greater ( not sure what you call it but 10mm move is definitely not a 10mm move more like 30-40mm ) so far i got the z axis moving and the x axis moving at least next is to connect up the y axis and then connect all of them up at the same time and check again.

    As far as endstops go the ones on the C2 are 2 wires but on the Ft5 they are 3 wires any idea if i can just connect two wires to the endstops instead of the 3?

    I have no idea lol. I dont have a C2 or a FT5, I'd say no that it needs all 3 (if its 3 wire there is a reason)

    Dustin Corbin has a piece on YouTube for adjusting voltage in steppers.

    I think if it were me I'd keep the FT 5 endstops. They must be using them in a special way to wire all 3 (something the firmware will look for)

    Well the robo main board only has 2 prings for the endstop and ill be editing the firmware if possible on the robo board for the build plate size and z acis height. So far all the motors are working the z axis though are runing backwards though so up is down and down is up im assuming its the way they are wired and just have to swap the wires around to get the correct position for them

    yea flip the connector on the board to get the z motors going in the correct orientation. I shot you a PM about the leftover c2 stuff :D

    Replied back. Ill try switching them and hopefully that works. Once i get that then its onto the firmware to try to change the size of the bed and height

    so im trying to change the config.h file for the size of the bed but what im not fully understanding is. I have to download the file from the robo github and edit the config.h file and upload the new one? or am i able to just edit the file that is already on the mainboard?

    you have to do it the first way using Arduino software.

    You have to download the entire firmware, edit the one file, compile and upload to the Arduino (OK, the control board)

    Correct bunch of files ... yes. Probably the only one you need to actually edit is CONFIGURATION.H

    Yeah, you might want to share what you changed. There are a number of interrelated settings and it is easy to loose track.

    the only thing i changed was the below from the original size the the updated size thats below. i notice when i first turn everything on i can hear the steppers kick on and you cant move them manually but then the raspberry looses connection to the board and the motors loose power.

    Code:
    // Travel limits after homing (units are in mm)
    #define X_MIN_POS 0
    #define Y_MIN_POS 0
    #define Z_MIN_POS 0
    #define X_MAX_POS 300
    #define Y_MAX_POS 300
    #define Z_MAX_POS 380
