For the motor config block, try:
; Motor Configuration !!! For stock motors
; !!! Also note that you should edit the current-sense-homing.g file and increase current to 50 on X and Y, 100 on Z.
; !!! M913 X20 Y20 Z60 ---> M913 X50 Y50 Z100
;
M350 X16 Y16 Z16 I1 ; Set X, Y, and Z microstepping with interpolation
M350 E32 I0 ; Set Extruder Microstepping without interpolation
M92 X100.00 Y100.00 Z400.00 E280.00 ; Set steps per mm
M566 X600.00 Y600.00 Z24.00 E300.00 P1 ; Set maximum instantaneous speed changes (mm/min)
M203 X15000.00 Y15000.00 Z900.00 E2000.00 ; Set maximum speeds (mm/min)
M201 X4000.00 Y4000.00 Z1000.00 E5000.00 ; Set accelerations (mm/s^2)
M906 X620.00 Y620.00 Z550.00 E550.00 I50 ; Set initial motor currents (mA) and motor idle factor in percent
M84 S1000 ; Set idle timeout before shifitng to idle-current
; Motor remapping for dual Z and axis Limits
M584 X0 Y1 Z2:4 E3 ; Set two Z motors connected to driver outputs Z and E1
M671 X-37:287 Y0:0 S10 ; Leadscrew at left connected to Z, leadscrew at right connected to E1
and also current-sense-homing.g:
; 0:/sys/current-sense-homing.g
; Set the current and sensitivity for homing, non-printing, routines
M915 X S2 F0 H400 R0 ; Set the X axis sensitivity.
M915 Y S2 F0 H400 R0 ; Set the Y axis sensitivity.
M913 X50 Y50 Z100 ; Set the X, Y, and Z drivers current percentage for non-print moves, per config.g.
Let me know if that helps.
