Hi,

I tried testing my printer but the motors go opposite directions and other issues.

I now understand that I have to upload new FIRMWARE to the RAMPS 1.4 printer control board. So it learns which way to turn the motors etc.
Is there a default file with all the default settings already in place available for this kitset?
Or a page of instructions showing what to edit and save as default?

I found this... http://www.geeetech.com/wiki/index.php/Ramps1.4
Are the settings in your wiki good for this kitset or all kitsets? or just a sample of what work is required?

Regards Lee

Hi,
Can you please advise me on the correct calculations for the firmware for this Kitset.
We need to know exactly the right configuration to setup in the firmware for stepping etc.
This kit has M5 rods for z axis but i dont know the pitch and it is something you could tell me.
Currently I have these set in firmware. Please advise what should be the correct ones as Z axis is a long way off.
Steps per unit and acceleration etc... what is correct settings in firmware for this exact kitset please.

Regards Lee


//// MOVEMENT SETTINGS
#define NUM_AXIS 4 // The axis order in all axis related arrays is X, Y, Z, E
#define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0} // set the homing speeds (mm/min)

// default settings

#define DEFAULT_AXIS_STEPS_PER_UNIT {85.333,85.333,2560,158.308} // default steps per unit for Ultimaker 78.7402,78.7402,200.0*8/3,760*1.1
#define DEFAULT_MAX_FEEDRATE {500, 500, 5, 25} // (mm/sec)
#define DEFAULT_MAX_ACCELERATION {9000,9000,100,10000} // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for Skeinforge 40+, for older versions raise them a lot.

#define DEFAULT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for retracts

Just a minor note: The YouTube video for adding the Z-axis stepper motors shows the technician installing them on the wrong side of the frame.
