I already have Mach3, but am thinking about changing over to MACH4. The decision is dependent upon some of Mach4's functionality. In Mach3, I can use "Formula Axis Correction" to insert a simple linear formula to adjust for X (or Y) being out of square in relation to Y (or X). For example, if X is out-of-square by .050 inches over 48 inches of travel, a correcting formula could be written: f(x)=X+Y*.00104. (.050/48=.00104). "Formula Axis Correction" is located under "Function Cfg's" > "Formulas" in Mach3. I've searched around in Mach4, but can't find anything that appears to provide the same ability to correct for out-of-square conditions.

Can anyone tell me where in Mach4 to find this functionality, or confirm that it doesn't exist?

Thank you,

Gary
