Would it be possible to change feed rate and perhaps also Z-depth on the go in FluidNC?
I just got my M4,1 up & running and during my first run i notised that I had put the feed rate to low in the CAM program.
To change the feed rate on the go would be a perfect feature while cutting.
Also z-depth would be nice to be able to change. Perhaps with an off-set to the G-code
All the best

AFAIK this is not possible in fluidnc

you could change the Z-home setting (but watch out that this may mean that
movement that is supposed to be above the material is now in the material)

Thanks David for the reply.
So I figured. Perhaps it could be a future feature.

Not possible, but if you load your GCode into a text editor you can look for Z- and change those to a new value and you can change the F to change the feed rate, then save file with a new name, same extension.

Thanks, Ian.
I ended up redoing the gcode in the CAM software with a higher feed rate.

That works too

I was wrong, this is possible in the fluidnc tab.
you can send commands directly via telnet or USB serial
from the google search:
luidNC allows you to change the feed rate in real-time using feed override
commands (10%, 1%, coarse/fine) via the web UI dashboard, serial commands (f+, f-), or by
modifying the F value in G-code (G1 X… F100). The Web UI offers panels for
overriding speed during jobs, and max/min rates can be configured.
Methods to Change Feed Rate
FluidNC Web UI (Real-time): On the dashboard/web interface, locate the feed
override buttons to adjust the percentage of the current feed rate while running a job.
Serial Commands (Real-time): Send these commands in the terminal:
f+ / f-: Fine Increase/Decrease Feedrate.
F+ / F-: Coarse Increase/Decrease Feedrate.
That’s great.

It’s these guys here
I have never pressed those tho so while they should work I’m not sure 
I second that it would be really nice to be able to adjust the depth of cut a bit while the gcode is running. I’ve several times discovered that I set my depth slightly off and I’m not quite cutting all the way through.
I gave it a try. The F adjustments work to adjust speed, obviously can’t adjust spindle speed. Clicking on X,Y and Z values (Left target) only works while not cutting
Thanks guys, This will make life much easier, or faster…
