No, you don't have that, what you have is a rate number which is no real path error value, it is just a rate which only indirectly influances the path error, but the path error will still depends on the acceleration settings of the axes.
You can't define the max.error in millimeters or inches, you can only guess about the error it will create on different paths.
Both Linuxcnc and UCCNC has real path deviation control, you can define the tolerances in length units and the software will obey that setting, will not create a larger path error than what you setup.

um...are you looking in the right spot? it has an angle and a distance setting in units.... actually i always found this setting a bit more useful and useful than the gcode deviation settings in linuxcnc. only drawback to the mach way is its not gcode accessible, and sometimes you want to be able to choose different settings per program or even in 1 program.
