BC SET BACKLASH
COMPENSATION
The BC command sets the backlash compensation factor for the currently active axis. This is a
numeric value of the number of additional steps output when a direction reversal occurs. The
additional steps output are intended to compensate for any mechanical play (known as backlash
or lost motion) that occurs when an axis changes directions from plus to minus or minus to plus.
BC? can be used to query the current parameter setting. Starting with V1.30 firmware (see WY
command), a question mark can follow the command in order to query the last parameter setting.
RANGE: 0 backlash 1024 Steppers
-1024 backlash +1024 Servos
Example: Set backlash compensation factor of axis X to 12 counts
Enter: AX;
BC12;
Response: None.
