Anet A8 with PyCNC

Hi!I have replaced the main board of my Anet A8 printer to a Raspberry Pi based one, running PyCNC (https://github.com/Nikolay-Kha/PyCNC). After many issues I have finally got to a point where all the motors work as well as heating and sensors.However I am unable to print due to the motors seem to run too much, not being precise. When I execute `x5` it moves more than 5 cm. How can I figure out what values should go to the config of PyCNC? I use Cura, maybe a different slicer/gcode format needs to be chosen? Thanks!!Config:# Maximum velocity for each axis in millimeter per minute.MAX_VELOCITY_MM_PER_MIN_X = 3000MAX_VELOCITY_MM_PER_MIN_Y = 3000MAX_VELOCITY_MM_PER_MIN_Z = 300MAX_VELOCITY_MM_PER_MIN_E = 150MIN_VELOCITY_MM_PER_MIN = 1# Average velocity for endstop calibration procedureCALIBRATION_VELOCITY_MM_PER_MIN = 300# Stepper motors steps per millimeter for each axis.STEPPER_PULSES_PER_MM_X = 50STEPPER_PULSES_PER_MM_Y = 50STEPPER_PULSES_PER_MM_Z = 50STEPPER_PULSES_PER_MM_E = 15# Mixed settings.STEPPER_PULSE_LENGTH_US = 2STEPPER_MAX_ACCELERATION_MM_PER_S2 = 3000 # for all axis, mm per sec^2SPINDLE_MAX_RPM = 10000EXTRUDER_MAX_TEMPERATURE = 250BED_MAX_TEMPERATURE = 100MIN_TEMPERATURE = 40EXTRUDER_PID = {"P": 0.059161177519, "I": 0.00206217171374, "D": 0.206217171374}BED_PID = {"P": 0.226740848076, "I": 0.00323956215053, "D": 0.323956215053}
