Parameter Help

[jc1976]

is anyone here familiar with changing parameters on a HAAS VF-3? have a 4th axis installed and need to have it rotated for each tool change, but dont want to write it in the program. i know how to change parameters for the x and y axis, but the 4th just goes to zero, whereas I need it to rotate 90 degs

If this is a case where the A axis needs to be in a home position prior to a tool change, you can set bit "Zero axis TC" in parameter 269. This will bring A to machine zero prior to any tool change. Parameter 212 can then be used to shift the home position of the A axis.
