Sorry but I have no idea regarding Mach wizards. It is tricky unless you are 90-degree arcs and I usually make mistakes when doing such manually.

they are all in IJK format, will it be too much trouble? easier to start over? does there happen to be a converter from IJK to R, ha ha? probably should just look for a wizard and do it over again.

Are your arcs defined in R or IJK format? If they are in radius mode it should be as simple as changing the radius. With IJK it is a little more complicated. See for a pretty good tutorial on how things work and possible pitfalls.

i am trying to be lazy at least for initial testing. my code is a mess developed over time. i also wrote it a long time ago using various tools and do not remember how they work but certainly can learn again if forced to.
so the last question is: if i have circular pockets using arcs is there any simple change to the arcs that can effectively compensate for a larger cutter? i have been making my pockets with something like cambam?
so i never really learned the syntax for arcs.
I know there are all sorts of wizards for mach4. i will look soon but is there something for creating simple shapes like circular pockets and a d slot which is two straight moves and two arcs?

Read the description for G41/G42 carefully since there are leadin/out requirements related to cutter diameter. If you were not previously using cutter compensation it is doubtful if your CAM follows those rules for an even larger cutter. Why not simply redo the CAM?

I am looking for a simple solution. I am using a 1/4" router bit to cut slots d shaped pockets and holes i would like to use a bigger cutter for various reasons. especially for testing i would like to do as little reprogramming as possible.
i have read about cutter compensation but can not make sense of it. is there a way to apply a cutter compensation and switch to a 3/8" bit and make the same sized slots holes pockets etc. Do i need to turn compensation on and off for each arc of a circle, for example or can i just make a 3/8" bit behave like a 1/4"? there are no features with a minimum inside dimension of less than 3/8"
