Mendel Firmware Settings (5 replies)

Hello there. This will be my second post since my first one was very successful on here before. :)

So I have been building my own CNC machine / 3d printer and have everything physically built. I can move the motors with Repetier Host. They move in the correct direction. My problem is setting the step/unit ratio. The default was around 30 or so for the x and y and after running the calculations I have set them to 1009 each. When doing this, the motors will no longer move. They make a very high pitch noise like they are receiving the output but won't move at all. My question is two fold. First of all, I assume that Repetier uses mm as the default unit of measure? So in manual mode when I click to go "100" that would mean to move 100 mm right? If this is correct then should there be something else I change when using such a high step/unit ratio?

Here are my settings:

// default settings

#define DEFAULT_AXIS_STEPS_PER_UNIT {1009.45, 1009.45, 711.51, 167} // default steps per unit x,y,z,e
#define DEFAULT_MAX_FEEDRATE {500, 500, 10, 100} // (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 1200 // X, Y, Z and E max acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION 1200 // X, Y, Z and E max acceleration in mm/s^2 for r retracts

//
#define DEFAULT_XYJERK 20.0 // (mm/sec)
#define DEFAULT_ZJERK 0.4 // (mm/sec)
#define DEFAULT_EJERK 5.0 // (mm/sec)
