Hi,
posting this here as I wrote it for my 2.4/350 Voron Stealthchanger.
I'll have to implement quite a bit of custom functionality for my envisioned "workflow" but found that code - both Klipper modules in Python and GCODE - can't be changed without Klipper reload and loss of homing.
Add Quad Gantry Leveling for toolchanges, possibly bed mesh, and this gets old real quick.
Enter "KlipperHotload" - my project - to (re)compile Python code on the fly. For what I need, it's a gamechanger, I will probably stop using GCODE files and code everything I need in Python.
In a nutshell (see README in above link) it provides one macro - I picked the letter "U" as it's not used in GCODE -
to run a given function from a given file, passing arguments (where {CONFIG} interpolates to the directory of printer.cfg). There are a few tricks built in to assist with keeping GCODE concise, e.g. PATH and FILE may need to be set only once, the last value becomes default.
If only a single function is required, it collapses to
or if I don't need arguments just
which is about as short as it gets
Speaking of "short", it's just a single ~200 line file in
I hope someone will find it useful.
