Hi Gvhf

When importing a G-code program, the following G-code import error is shown: “Tool height compensation has no effect.” Could you provide an explanation and/or supplementary documentation for how RoboDK interprets all G-code commands and reasons for this error?

This error shouldn't affect the imported G-code.
All useful G-code commands are interpreted by RoboDK.

What impact do the Path to Tool Offset and Select Algorithm , specifically Minimum Tool Orientation Change and Tool Orientation Follows Path , parameters have on importing and exporting G-code files? Does this affect the accuracy of the simulation?

Path to Tool offset will create an Offset between the path and the active tool following the orientation of the selected reference frame.
Minimum tool Orientation Change and Tool Orientation Follows Path has no effect on the imported points and their precision. It only affects the orientation of the tool with respect to the path.

从RoboDK的文档”,因为一个六轴机器人is used to follow a 3-axis or 5-axis CNC manufacturing program we have an additional degree of freedom to define. This degree of freedom is usually the rotation around the Z axis of the TCP." Are there ways in RoboDK to fully constrain this motion about the 6th axis so RoboDK does not manipulate the G-code commands and orientation(s)?

Simply bring the "Optimization parameters" to zero. You will, therefore, lock the rotation around the Z-axis.

Have a great day.
