Gasherbrum-K3 VS strayr-k-macros

Also, I hate to recommend a not voron based build but https://github.com/Annex-Engineering/Gasherbrum-K3 is my next printer. Small but has the volume you want, and is the fastest FDM printer I’ve seen. Not as user friendly to build as a voron from what I’ve seen playing with the idea. Not that I expect it to be a problem.

Hey that's a nice printer. I had a look at https://github.com/Annex-Engineering/Gasherbrum-K3 It reminds me of a Voron crossed with a Hypercube.

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.
