PAM for RatOS

Print Area Mesh for RatOS

Adds dynamic mesh calibration to your RatOS printer.

• works out of the box with any printer running RatOS
• respects all RatOS probe and mesh settings

1. Install

SSH into your Raspberry PI and execute:

cd ~/
git clone https://github.com/HelgeKeck/pam.git
bash ~/pam/install.sh

2. Activate

Add this to the overwrite section at the end of your printer.cfg file.

# PAM
[include pam/pam.cfg]

3. Modify your slicers start print g-code

• PrusaSlicer / SuperSlicer

MESH_CONFIG X0={first_layer_print_min[0]} Y0={first_layer_print_min[1]} X1={first_layer_print_max[0]} Y1={first_layer_print_max[1]}
START_PRINT EXTRUDER_TEMP=[first_layer_temperature] BED_TEMP=[first_layer_bed_temperature]

• Ideamaker

MESH_CONFIG X0={print_pos_min_x} Y0={print_pos_min_y} X1={print_pos_max_x} Y1={print_pos_max_y}
START_PRINT EXTRUDER_TEMP={temperature_extruder1} BED_TEMP={temperature_heatbed}

• Simplify 3D V5

MESH_CONFIG X0=[build_min_x] Y0=[build_min_y] X1=[build_max_x] Y1=[build_max_y]
START_PRINT EXTRUDER_TEMP=[extruder0_temperature] BED_TEMP=[bed0_temperature]

• Cura

MESH_CONFIG X0=%MINX% Y0=%MINY% X1=%MAXX% Y1=%MAXY%
START_PRINT EXTRUDER_TEMP={material_print_temperature_layer_0} BED_TEMP={material_bed_temperature_layer_0}

To make PAM work with Cura you need to install a post processing plugin

1. in cura open menu Help -> Show configuration folder
2. copy MeshPrintSize.py into the scripts folder
3. restart cura
4. in cura open menu Extensions -> Post processing -> Modify G-Code and select Mesh Print Size

4. Update
