Collection of stuff for Creality Ender 3 3D printer

Build

Ender 3 with Creality glass bed
Build using "Precision Alignment Guide" from Luke Hatfield (Thanks!!!) from facebook user group.

Firmware

Flashed bootloader using Arduino Decimila as ArduinoISP. This needs an 100 Ohm Pull-Up between Arduino RST and 5V otherwise the uploader just finds the Decimila.
Installed firmeware using this bootloader.
Currently used Marlin 1.1.9 with configuration taken from https://github.com/wronex/Marlin-Ender-3
Activated manual mesh leveling with 9 points

PlatformIO USB access: https://docs.platformio.org/en/latest/faq.html#platformio-udev-rules Restart OS afterwards!

Extruder calibration

Disconnected PTFE tube -> 100 mm result in 96 mm output M503 shows 93 steps/mm Original extruder steps/mm value × 100 mm = total steps taken: 93 × 100 = 9300

From that, we can extrapolate that calibrated extruder steps/mm value (y) × actual extruded distance = total steps taken: y × 96 = 9300

Therefore, calibrated extruder steps/mm value (y) = total steps taken / actual extruded distance: y = 9300 / 96 = 96.875 Use M92 E96.875 to upload it M500 to save it Test it again See its to much, measure and calculate again Set to 95 steps/mm

Test again at end of tube change it in Marlin FW!

##Leveling: Manual mesh bed leving from printer options

• preheat PLA
• Start proccess
• Set z value for all 9 points (paper)
• Store settings!
• Add M420 S1; to start gcode after homing to load stored mesh!

Filaments

3DEE PLA +Good color and good printing experience ~Cartboard box -No vacuum seal or silica gel -One clog due to thick part in filament (spliced together?)
