CoreXY Diagram

To configure your HBot or Corexy, set the arm_solution parameter in your configuration file to either corexy or hbot. For example:

arm_solution corexy

If you are using homing, also uncomment the corexy_homing line in the config.

It is recommended to set the alpha_max_rate and beta_max_rate to the highest speed your steppers can achieve. These settings refer to the actuator speed (the X and Y steppers), which on a corexy can run nearly twice as fast as the requested Cartesian speed when moving in certain directions.

Getting Direction Right

Movement in the X or Y direction always involves both alpha and beta motors, which can make configuring a corexy solution confusing. If you find that movement is incorrect after wiring and configuring your printer, the following solutions may help:

Problem Possible Solution
My axes are swapped Invert the signal of one motor by adding or removing ‘!’
One of my axes goes in the wrong direction Swap the alpha and beta cables or swap the pin assignments
