M106 remap to M67

is there a way to create a new mcode (m106) which would allow for a synchronous remap to M67

looking for options to easily remap lightburn output.... it seems that they have output grbl for pwm control


I have asked on the lightburn forum about why they are using M106 with what they have listed as a Linuxcnc post processor, so maybe they can sort out their end. They don't seem to provide easy access t edit the post processor (like you can in sheetcam) and you can change stuff according to your needs

thanks Andy

the M106 just looks like this

M106 S1000
.....
M106 S500

(you can rescale the S val in lightburn ).... almost the only adjustment given

I filter may be an interesting idea to swap out m106 for M67 even if just to learn about

Could the following be used to convert the 0-1000 supplied by Lightburn to the 0-1 required by the M67?

For example S500 would be 500/1000 = 0.5
Resulting in M67 E0 Q0.5

has this been resolved? I ask because I would also like to remap Lightburn code but wondered if it is possible to remap depending on the S value.
What I would like is that M106 S0 be remapped to M68 E0 Q0 and M106 S500 be remapped to M67 E0 Q(#<S>/1000),
I have tried reading the remap documents but it's a bit confusing for me at this stage.
Maybe one day Lightburn will have the option to do this in their PP.
thanks

Thanks for the response Andy, I did read that so not sure if it would work either, but I made a work around by creating a bash script with 2 sed commands (been ages since I did any bash scripting)
FYI or anyone else reading this my bash script is
#!/bin/bash
sed -i 's/M106 S0/G68 E0 Q0/g' $1
sed -i 's/M106 S/G67 E0 Q/g' $1
I saved it as RunSED (no imagination)
made it executable chmod +x RunSED
and then run it with ./RunSED 'filename'
seems to work OK
