klipper VS strayr-k-macros

There is _a lot_ wrong with Marlin. It is a complex codebase, full with ancient artefacts, litterred with preprocessor ifdefs every 2-3 lines of code, dynamic includes in the middle of CPP files, etc[1]. It's about as unreadable as C++ code gets--well, I guess it's not template metaprogramming.

Klipper by contrast is a breeze to read through[2].

I am very grateful for Marlin, for all of reprap, and everyone who has contributed to it. But saying there is nothing wrong with it is straight up misguided.

That's the cfg from my photo https://github.com/Klipper3d/klipper/blob/master/config/generic-mks-sgenl.cfg Just confuses me more

If you have (like me) problems getting the auto reconnect solution mentioned on klipper https://github.com/Klipper3d/klipper/issues/835 running.

Did you check the printer cfg examples folder? Looks like there are a few BTT octopus cfg in there.

Compare your current printer.cfg with the master example here. https://github.com/Klipper3d/klipper/blob/master/config/printer-creality-ender3-2018.cfg

I found scripts to handle this problem, like this here: https://github.com/Klipper3d/klipper/issues/847

Guys, I hope someone who has it could send me the printer.cfg of the Ender 3 V2 Neo, I found it here on github, but it seems that some things are out and don't work the right way. Thanks!

I use this macro to do square the gantry against the top frame You should only do this if you have adjustable current for your stepper drivers ([tmcxxxx] sections in your config for stepper_z and stepper_z1 drivers) You'll also want to make sure your stepper_z.position_max is just before the gantry would contact the frame.

I've added it into my LCD menu https://github.com/strayr/strayr-k-macros/blob/main/improved_menu.cfg, but beware, some of the menuitems pull in macros from other parts of the package. You may find the whole lot useful, read the docs. it needs some updating and perhaps the probe menu splitting into a standalone file.

I use u/strayr-k's macro for this: mechanical_level_tmc2209.cfg

I always use strayrr-k's mechanical gantry calibration macro to tram the gantry against the frame before using screws_tilt to level the bed.

Last note, the G34 macro I use is this one. Works really well on my dual Z setup (one driver for both steppers). I've noticed my Ender3 X gantry likes to set itself just a bit off-kilter when steppers are disabled, so I run a G34 at every startup to ensure it stays level as long as the motors are enabled.

you can try this https://github.com/strayr/strayr-k-macros/blob/main/M204.cfg but it can cause crashes if you have gcode with lots of accel changes, I encountered this on small mmu prints with lots of very short perimeters but it might be ok.

I use mech_gantry_cal.cfg a lot, but that only applies if you use dual z steppers and dual z drivers. This macro will bump the gantry against the z_max to straighten it against the frame and eliminate any drift between the drivers.
