Movement Configuration

These are settings used for Movements. Settings with EEPROM in the description can be updated through the Repetier Host user interface without requiring a full firmware flash.

Steps Per MM:

• XAXIS_STEPS_PER_MM - 78.8177
• YAXIS_STEPS_PER_MM - 78.8177
• ZAXIS_STEPS_PER_MM - 320

The X and Y steps/mm is actually 78.817734, but I have calculated that this difference is only 1.6 nanometers over the distance of 310mm - I don't know about your accuracy requirements, but I can't measure that small. Having more decimals also seems to cause issues in the firmware

Axis Maximum Length:

These values are the absolute maximum, which will prevent a move greater than this. It is your responsibility to ensure your slicer does not generate a move outside of the printer that you determined as safe.

I usually test my maximums by jogging the axis 1mm at a time, until a maximum is achieved, then subtract a few mm's and use that value in the firmware.

• X_MAX_LENGTH - 310
• Y_MAX_LENGTH - 210
• Z_MAX_LENGTH - 600

The Z_MAX is able to handle full sized D5 printers, but if you want to reduce it for a Mini, you are welcome.

Axis Speeds:

The maximum speed allowed in each axis:

• MAX_FEEDRATE_X - 200
• MAX_FEEDRATE_Y - 200
• MAX_FEEDRATE_Z - 30

Homing Speeds:

• HOMING_FEEDRATE_X - 40
• HOMING_FEEDRATE_Y - 40
• HOMING_FEEDRATE_Z - 20

Acceleration Print:

• MAX_ACCELERATION_UNITS_PER_SQ_SECOND_X - 1000
• MAX_ACCELERATION_UNITS_PER_SQ_SECOND_Y - 1000
• MAX_ACCELERATION_UNITS_PER_SQ_SECOND_Z - 100

Acceleration Moves:

• MAX_TRAVEL_ACCELERATION_UNITS_PER_SQ_SECOND_X - 2000
• MAX_TRAVEL_ACCELERATION_UNITS_PER_SQ_SECOND_Y - 2000
• MAX_TRAVEL_ACCELERATION_UNITS_PER_SQ_SECOND_Z - 100

Jerk (how fast it may go around a corner):

• MAX_JERK 10
• MAX_ZJERK 0.3

Homing Order:

• HOMING_ORDER - HOME_ORDER_XYZ
  • Set order of axis homing. Use HOME_ORDER_XYZ and replace XYZ with your order.
