Hi everyone,
I’ve been trying to get my printer running properly for some time now, but I keep having problems with the extrusing rate, the setting below is what i’ve flashed into my printer.
However whatever I do to the extrusing value, the amount of extrusion does NOT change.
I’ve tried values like 100, but also 8000.
When I extrude in pronterface or simplify3D (100mm) it won’t matter, it will only extrude something like 1cm of material.
#define DEFAULT_AXIS_STEPS_PER_UNIT {160, 160, 8000, 1550}
I’ve got a mendel prusa p3steel xl with a e3d v6 bowden extruder running marlin 1.1.0-RC2.
When testing the extrusion I offcourse work without the hotend attached. 
It may be using values stored in eeprom and overriding anything you upload. You can try disabling EEPROM support in configuration.h and reuploading again. You can also run the eeprom clear program in the arduino software.
This makes a lot of sense, the EEPROM support is indeed enabled, I will try both options (first a EEPROM clear) if that doesn’t change anything I’ll disable the support in the configuration.h
Thanks for your reply!
Why would you disable the EEPROM instead of just using it? It allows you to change those settings on the fly which is very useful especially if you don’t already know what exact values you need.
