Bed Mesh Calibration
By default, RatOS calibrates the bed mesh before each print. If you prefer calibrating your bed mesh manually, you can disable it. Disabling variable_calibrate_bed_mesh will stop RatOS from loading a bed mesh entirely. If you want it to load a mesh, you can set variable_bed_mesh_profile to the name of the profile you want it to load.
| Name | Possible Values | Default | Description |
|---|---|---|---|
| variable_calibrate_bed_mesh | True / False | True | Whether or not to calibrate a bed mesh before each print. |
| variable_bed_mesh_profile | undefined / string | undefined | The name of the profile you want to load. |
If variable_calibrate_bed_mesh is False, you must set variable_bed_mesh_profile variable to the profile name you wish to load, or no bed mesh will be loaded. If variable_calibrate_bed_mesh is True and this variable isn't set, RatOS will use ratos as the profile name.
Adaptive Meshing
RatOS comes with its own deeply integrated and IDEX-aware adaptive meshing implementation. Do not try to set up the Klipper variant of it, which works only in combination with the exclude_objects feature. RatOS will only probe the print area and your configured probe location, potentially saving a lot of time on smaller prints on bigger printers. RatOS will keep the resolution of your mesh (probes per mm), so that you always get consistent mesh performance. Contrary to other implementations, RatOS doesn't move your prime location, instead it probes the prime location (constrained by min/max bed_mesh settings) and uses the difference between the probe result and your z_offset to dynamically apply a gcode offset only for the prime macro. This ensures no collision with the prime blob and the toolhead on small meshes.
Adaptive Meshing Configuration
Adaptive bed meshing is enabled by default. To disable it, set variable_adaptive_mesh to False in your printer.cfg file.
| Name | Possible Values | Default | Description |
|---|---|---|---|
| variable_adaptive_mesh | True / False | True | Whether to enable adaptive meshing |
Adaptive Prime Blob Configuration
For single toolhead printers, you can control the location and direction of the prime blob. IDEX printers use a fully automated and intelligent prime control depending on the situation and print mode.
| Name | Possible Values | Default | Description |
|---|---|---|---|
| variable_nozzle_priming | "primeblob", False | "primeblob" | Whether to enable the prime blob |
| variable_nozzle_prime_start_x | "min", "max", Number | "max" | non IDEX priming x-location |
| variable_nozzle_prime_start_y | "min", "max", Number | "min" | non IDEX priming y-location |
| variable_nozzle_prime_direction | "auto", "forwards", "backwards" | "auto" | non IDEX priming y-direction |
| variable_nozzle_prime_bridge_fan | Number | 102 | priming bridging fan speed 0-255 |
Prime Blob X-Margin
By default, the prime blob has an x-margin of 5 mm from the edge. This value can be changed by overriding it in the printer.cfg.
[gcode_macro PRIME_BLOB]
variable_x_offset: 5 # the prime blob x-margin
Slicer configuration
Make sure to setup your slicer according to the official RatOS slicer configuration.
Zero reference position
RatOS Adaptive Meshing currently doesn't modify the zero reference position, it's generally not advised to set the zero reference position with adaptive meshing.
