Replace part of Gcode

Axel Dekeyser

Hi,

I want to replace a part of my Gcode.
Example:
G1 Z0.250 F1800.000
G1 X84.650 Y85.654 F1800.000

I can’t simply replace the F1800.000 because it is used in other parts. I only want to replace the F1800.000 with F90.000 in the lines with Z. The number behind the Z also changes.
So for the example. The first line has to change but the second line has to be the same.

I already tried:
Find: G1 Z(.*) F1800.000
Replace: G1 Z\1 F90 \nG1 F1800

Where’s the mistake? It doesn’t change anything. Do I have to change the search method?

Thank you :),

Axel

Hallo @Axel-Dekeyser,

Do I have to change the search method?

Yes, if you didn’'t use regular expression

with the regular expression it also doesn’t change what I want.
Is the Find and Replace that I use correct?

Well it depends, your replace does more than you have described,
so I don’t know if it is expected or just an error.
If you could give something like

This is what I have
and
this is what I want to have

we can definitively say what is going wrong.
So from what you described, you wanna replace F1800.000
value in lines with Z coordinates, which of course will differ…
From your description it is only needed to have
G1 Z\1 F90

There is room for simplifying the regex like
Find: (G1 Z.* F)1800.000
Replace with: \190

But your find/replace should work as well.

With the simplification it worked fine :)

Thank you so much Claudia.
