Other parameters and correction targets can be set in the general SD 54760 $SNS_MEA_FUNCTION_MASK_PIECE .
1)
The contact angle always refers to the positive direction of the 1st axis of the active coordinate system, e.g. for G17 to +X,
2)
G18/+Z, G19/+Y
The sign of the incremental angle specifies the positioning direction of this angle.
