wantai specs are:

black= A+
green = A-
blue= B-
red= B+

that´s aliexpress says about.


my question is:
2B/ 2A/ 1A/ 1B RAMPS matches A+/ A-/ B+/ B-?

if so, I´ve tried:
BLACK/ GREEN/ RED/BLUE
BLACK/ GREEN/ BLUE/ RED

and also:
RED/BLUE/ BLACK/ GREEN

the 3 combination produces the same results. Despite of spinning in the right direction, the motor can´t barely move.

stepstick has R=100 OHMS, VREF is 0,5V

1/4 microstepping (X,Y,Z) - only middle jumper attached
1/16 microstepping(E) - all jumpers attached

X, Y and Z axis are D=12mm and Pitch= 4mm
Extruder is D=11mm 26 tooth gear

#define DEFAULT_AXIS_STEPS_PER_UNIT {200.0, 200.0, 200.0, 95.0}
#define DEFAULT_MAX_FEEDRATE {50, 50, 5, 30} // (mm/sec)
#define DEFAULT_MAX_ACCELERATION {200,200,200,200}

#define DEFAULT_ACCELERATION 200
#define DEFAULT_RETRACT_ACCELERATION 200

there are lot of variables to play with. I got confused trying to isolate the error. I have been almost a week with no progress at all.
the only thing I know for sure is that RED/BLUE are a pair. I have no more ideia to change.
