8. Click on Load.
Loading starts, first compiling the program for errors, and then, properly speaking, loading the firmware on the me-
mory board.
9. If the process is completed successfully the message Charge completed is displayed and the printer is ready to use.

Hysteresis correction and backlash
The hysteresis effect is purely mechanical and derived from the backlash from some of the components used in our
BCN3D+ printers. It occurs when a change in the direction of the platform to follow a given drawing suffers from a
delay. It’s present in changes in the Y axis.
The result can be noticed especially when printing circles, where a lengthening of the shape of the circumference in
the point the axis shifts is produced.
The solution implemented in the firmware allows to force an X and Y axes correction right at the moment it changes
direction. The printing platform is forced to correct its position going up or down to compensate depending on the
direction in which the change occurs, thus the hysteresis and the elongation above mentioned disappear.
