A feature of CAMBOX allows the use of TABLE values that don't start at 0. The CAMBOX motion should use the first value as an offset for the rest of the table.
In the MC4 range firmware V2.0246, a bug was introduced that causes a jump in motion when a table start value other than 0 is used. The jump may cause an unexpected movement on the axis, or it may cause the axis to trip out on Following Error.
The bug was fixed in V2.0252, so any version after that will process the Cam Table values correctly.
