H-Bot and CoreXY Configuration
H-Bot
CoreXY
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 |
