Marlin Settings for Geared Extruders

Marlin is Acting Up

This [1] shows how to set up Marlin for a geared Titan Aero extruder. Setting the Axis steps was done - yet extrusion happens now at a very slow rate, almost invisible. Testing extrusion in Cura works as it should - only to fail upon running a print. What gives??

• Could config.ino be overriding steps per mm?
• Hint - do M92 E837 in the start gcode? Save with M500
• Note that currently EEPROM is on in Configuration.h
• Note that listing EEPROM settings with M501 -

> M501 < echo:Hardcoded Default Settings Loaded < echo:Steps per unit: < echo: M92 X80.00 Y80.00 Z80.00 E837.00 < echo:Maximum feedrates (mm/s): < echo: M203 X300.00 Y300.00 Z10.00 E25.00 < echo:Maximum Acceleration (mm/s2): < echo: M201 X3000 Y3000 Z100 E10000

• Note that max feedrate on Z is problematic - E25.00. Set that to 200
