RRF-PAM

Print Area Mesh for RepRapFirmware

Adds dynamic mesh calibration to your RepRapFirmware printer.

• Should work out of the box on any RepRapFirmware
• respects all probe and mesh settings
• This script will also run G29 so it's not needed to do that separately anymore

1. Install

1. Copy the contents of the print_area_mesh.g file in the repo.
2. Move to your RRF interface and create a new file named print_area_mesh.g in system
3. Paste the content you copied in step 1.

2. Alterations

The file allows you to change a few things

deviationFromOriginal This value determinens when the print area mesh will be activated. If the print area is within the deviation from the original, the original probe settings will be upheld Change this if you want the print area mesh to be activated at a different deviation

minMeshPoints This value will determine the minimal amount of probe points that will be used

maxMeshPoints This value will determine the maximum amount of probe ponts that will be used

3. Modify your slicers start print g-code

Replace your G29 command with the specified command for your slicer

• PrusaSlicer / SuperSlicer

M98 P"sys/print_area_mesh.g" A{first_layer_print_min[0]} B{first_layer_print_max[0]} C{first_layer_print_min[1]} D{first_layer_print_max[1]}

• Ideamaker

M98 P"sys/print_area_mesh.g" A{print_pos_min_x} B{print_pos_max_x} C{print_pos_min_y} D{print_pos_max_y}

• Cura

M98 P"sys/print_area_mesh.g" A%MINX% B%MAXX% C%MINY% D%MAXY%

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
