I've got some g-code that I need to scale the X and Y values on so I am thinking of writing a tool that (1) reads in the file, (2) allows you to specify the prefix you want to change (like X), (3) can change the offset or scale of the prefix items value, and (4) saves the file. Does anything like this exist already before I go through the trouble of writing something?

This may do what you need.

Thanks jfong - that does look handy. I went ahead and threw this together for anyone else you might want to use it too.

It can scale (multiply by a value) any parameter (X, Y, Z, I, J, etc., also scaling with a value of -1 will mirror an axis.)

It can offset (add a value) any parameter.

It can make the precision consistent with rounding.

It will highlight what it changed.

You can copy/paste directly to the text window.

It can display the minimum, maximum, and difference (max-min).

It has a single change undo.


How to use it:

It only works on one AXIS at a time! If you need to scale both the X and Y axis by 0.1, this will have to be done in two change operations, first with X, then with Y. It does support multiple letter prefixes as well, for example, I use variables like #1022=12.4 and if I put "#1022=" in the prefix box, I can change these values as well.

Just paste some G-Code into the text box.

Set the prefix to what you want to change.

Set the precision you want.

Select scale or offset.

Set the value to the value you want.

Click the Change button.

Repeat until you are happy with it, then copy to clipboard and paste it into a notepad, etc.
