9.2 How to change the motor direction in firmware?

In the configuration.h tab of firmware, find the following codes. Change the true of corresponding

axis into false or false into true, and save the firmware and burn into the printer. ( Because you don’t

know the firmware which has been burned by mother board is true or false, it may be necessary to

burn both of the two parameters.)
