Optimal slicer settings

qlqlo

I noticed a header in the docs of calibrating the printer which points to the optimal slicer settings. Why is there nothing to see? I would be interested in seeing the setting for PrusaSlicer

@qlqlo I don't think there is an 'optimal' slicer settings, because the nature of boards running RepRapFirmware is that they end up in custom machines, doing customised jobs. There are a couple of settings to improve compatibility of Gcode with RepRapFirmware.

PrusaSlicer (I've just updated to 2.8, so these may be in different places on older versions)
Printers > General > Firmware > G-code flavor: choose "RepRapFirmware"
Printers > General > Firmware > G-code thumbnails: set "160x160/QOI" for compatibility with PanelDue
Printers > General > Advanced > Use relative E distances: enable this
Printers > Machine limits > General > How to apply limits: choose "Use for time estimate" to stop Prusaslicer overriding speed, acceleration and jerk settings in config.g

Edit: another one I remembered. To get the layer count correct on the DWC progress chart, add ;LAYER:[layer_num] to the custom gcode tab under the Before layer change G-code section

Cura (using 5.7.2, though generally I use Prusaslicer)
Settings > Printer > Manage Printers > (select printer) > Machine Settings > Printer (tab) > G-code flavor: select RepRap
In Print settings:
Special Modes > Relative Extrusion: check this is ticked, it should be if G-code flavor: RepRap is selected

I would welcome any settings suggestions for other slicers, eg Orcaslicer

@droftarts just a note you need the Printer Settings plugin in Cura to enable firmware retraction.
