Tevo Black Widow and Duet WiFi

Klaus.Waelde

Hello everybody,
Has anyone of you a basic setup for a stock black widow run on a duet wifi board. The y-axis works now but I cant replicate it to the x- and the z-axis. I'm looking for good start values for

Set maximum instantaneous speed changes (mm/min)
Set maximum speeds (mm/min)
Set accelerations (mm/s^2)
Set motor currents (mA) and motor idle factor in per cent

Any help would be greatly appreciated.

Thank you very much in advance

Klaus

i would start of with the tevo values for marlin

# code block
#define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0}  // set the homing speeds (mm/min)

// default settings

#define DEFAULT_MAX_ACCELERATION      {1000,1000,100,10000}    // 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          1000    // X, Y, Z and E acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION  3000    // E acceleration in mm/s^2 for retracts
#define DEFAULT_TRAVEL_ACCELERATION   1000    // X, Y, Z acceleration in mm/s^2 for travel (non printing) moves

// The speed change that does not require acceleration (i.e. the software might assume it can be done instantaneously)
