Z Tramming for 3d printers running Klipper, that do not have separate drivers for the z axis.
If the printer is not perfectly square, the z axis will not move in level. This means your nozzle could be at different heights at different sides of the bed.
Some 3d printers, like the Sovol SV06, do not have separate drivers for the z axis. Thus automatic calibration of the axis is not possible, as the motors are not independent.
This is a solution to this problem. But it requires some manual adjustments of the z axis motors.
The macro probes each side of the bed, then calculates the amount you need to rotate one of the motor screws. If we have to rotate clockwise by 1 hour and 20 minutes, it means that we need to rotate the motor 1 full rotation for the hour, then another third of a rotation for the 20 minutes. Calculation is done using the lead of your lead screw. This is the only input you need to provide.
As more people use this and contribute, I will strive to keep a list so that it becomes easy.
Simply run the Z_TRAMMING in your console.
Your printer will probe and then use Mainsail's prompt to inform you what to do next.
Continue till you are happy.
G28 Z if you abort without using the prompt.
See this for the reason.
To ease installation, there is a script you can simply curl and execute.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Jomik/klipper-z-tramming/main/install.sh)"Then you only need to configure your lead screw lead. See How to configure it?.
- Clone this repository to your printer's Klipper host.
git clone https://github.com/Jomik/klipper-z-tramming.git ~/z_tramming- Symlink it to your config folder.
ln -s ~/z_tramming/macros ~/printer_data/config/z_tramming- Copy the
z_tramming_settings.cfgto your config folder.
cp ~/z_tramming/macros/z_tramming_settings.cfg ~/printer_data/config/z_tramming_settings.cfg- Include the macros in your
printer.cfgby adding these lines:
[include z_tramming_settings.cfg]
[include ./z_tramming/z_tramming.cfg]- Add the repo to moonraker
cat >>$HOME/printer_data/config/moonraker.conf <<EOF

Open z_tramming_settings.cfg.
There is an example of what values can be configured together with their defaults.
