Set arm_solution to corexy or hbot in config, for example, add this line to your configuration file :

<code>
arm_solution      corexy
</code>

Then uncomment corexy_homing in config if using homing

Also it is recommended to set

<code>
alpha_max_rate
beta_max_rate
</code>

to the top speed your steppers can go, as these 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 going in certain directions.

== Getting Direction Right
Movement in the X direction or Y direction always involves both alpha and beta motors.  This can make it confusing to configure a corexy solution.  If you find that after wiring and configuring your printer that movement is wrong, then these possible 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 |
