I'm currently using Marlin firmware (1.1.0-RC7 - 31 July 2016) and would like to experiment with print speed.
In the file Marlin_main.cpp
I see in the process_next_command()
function, there is a variable called current_command
which (supposedly) holds the G-Code values for travel distance and feedrate(speed).
I'm expecting the actual command for travelling to look something like this:
G1 X50 Y25.3 E22.4 F1500
but I'm getting tied up figuring out exactly where it is. I'm assuming if I can change F1500
to F200
, I can effectively slow down the print speed.
I'm aware of line 753 in the configuration.h
file:
#define DEFAULT_MAX_FEEDRATE {300, 300, 5, 25} // (mm/sec)
I'm not interested in setting a fixed slow feedrate but would rather change individual G-Code commands. Can someone tell me where I can find the actual G-Code command to edit it?
