Remap G04 from P code F code was created by CNC4Life

Hello people I have a machine I’m retrofitting that has two sisters machines that are not retrofit. The original controller uses F instead of P on G04. Is there a relatively easy way I can fix this so all the machines can run the same code?

I was going to remap it but found on the man pages it’s protected.

Any help would be appreciated.

I think a filter program could be a solution:

linuxcnc.org/docs/devel/html/gui/filter_programs.html

So you could write a python code to search your gcode for 'G04 F' and replace it with 'G04 P'.

Here is a filter file that might do the job:

#! /usr/bin/python
import re
import sys

infile = sys.argv[1]
f = open(infile, 'r')
for line in f:
    print(re.sub(r"G0*4\s*P\s*(\d*)",r"G04 F\1",line), end="")

It works for me, anyway, to change P04 to F04. If you want to go the other way switch the P and F in the regex strings.

He gets :
G04 Pn << n= number of seconds to wait
He needs :
G04 Fn << n= number of seconds to wait
At least that is what i understood from his post.

You are correct I just need to change G04 Fxx to G04 Pxx

for line in f:
print(re.sub(r"G0*4\s*P\s*(\d*)",r"G04 F\1",line), end="")

So then you just need to swap P and F as suggested. Try:

for line in f:
    print(re.sub(r"G0*4\s*F\s*(\d*)",r"G04 P\1",line), end="")
