Temporary Path Tolerance | Acu-Rite CNC 3500i instruction

7.1 Explaining Basic Cycles

Temporary Path Tolerance

The PathTol command is used to temporarily override the parameter for path tolerance. This should only be used in a program and should be programmed by itself. The value in the system configuration is restored at the end of the program. The typical default is 0.010 mm (0.0004"). This can be useful if the 3500i hesitates between small moves, such as with a 3-D surface output from CAD-CAM. The feed rate for corners and curvatures is limited so that error does not exceed this value.

Select the More Milling button, and then "PathTol" from the pop-up menu.

Conversational format: PathTol

G-code format: G1000

Field	Code	Description
PathTol	X	The path tolerance for contour transitions.
		The MM range is from 0.0001 to 10.
