Connect the StepRocker to USB and MPF can control any steppers connected to it.
TODO: Add a picture of a StepRocker
This is an example:
hardware:
platform: virtual
stepper_controllers: trinamics_steprocker
trinamics_steprocker:
port: /dev/ttyACM0
steppers:
# Scenario: 1.8 degree stepper attached to a 7:1 gear ratio with homing flag that you want to control in units of revolutions
positionStepper:
number: 0
homing_direction: clockwise # when facing the shaft
homing_mode: hardware
reset_position: 0
reset_events: test_reset
named_positions:
0.0: test_00
0.6: test_01
1.0: test_10
platform_settings:
move_current: 25 # percent
hold_current: 5 # percent
homing_speed: 0.1 # user units/sec
microstep_per_fullstep: 16 # 1/16 mode (1 step = 1/16 of a full step)
fullstep_per_userunit: 1400 # UU=1 Revolution = 200 full steps per rev (1.8 deg stepper) * 7 gear ratio
velocity_limit: 0.5 # user units/sec (so, 0.8 RPS of output gear )
acceleration_limit: 2.0 # user units/sec^2 (so, 2 RPS^S of output gear)
