Purpose

I would like to unleash the power of my Ender 5 Plus(here after referenced as E5+) by removing the "bottleneck" that the weak mainboard processing power introduce. I also need to keep the cost as low as possible. Klipper supposedly should do just this, by moving all data processing from the E5+ mainboard on to the Raspberry Pi 4 i got connected already anyway.

First try/step will be a combo of Klipper and Octoprint. This makes it easy to flash the Klipper firmware onth the E5+ and I already got OctoPrint running at a Raspberry Pi 4 connected to my E5+ so...

Later i might try the Klipper + Moonraker + MainSail combo.

Klipper + OctoPrint combo

An installation guide is avilable on the Klipper website. I will follow that now.

make menuconfig will ask for microcontroller - the E5+ uses atmega2560. See printer-creality-ender5plus-2019.cfg

You(and I) MUST read, understand and perform the Config checks - Manual Leveling - Probe Calibration & Bed Leveling BEFORE you try to print!!

The overview page is a valuable resource of information so i got a lot of reading to do ;-)

Depending on the result of the first Benchy test print I believe that the next tuning should be done in this order:

Resonance compensation: A tool to reduce ringing in prints.
Extruder E steps - I skipped this because the test prints didn't show _any_ signs of over- or under-extrution.
Extruder nozzle temperature - I skipped this because i already know what temperature the PLA i use need to be printed at on my E5+
Pressure advance: Calibrate extruder pressure.

Klipper + OctoPrint problems I ran into

OctoPrint reported errors in the Gcode that turned out beeing related to hidden ascii codes in the start_gcode. Solution was found somewhere on the Intarwebs i cannot recall. I copied the Start and End G-code from Cura int Notepad++ and manually replaced all spaces with new ones. I could not see any difference on the spaces before and after BUT it worked so who cares ;-)

Klipper + Moonraker + MainSail combo

will be addressed later ...

Reference pages

My cry for help in the Danish Facebook group Den seriøse Ender-3/Ender-5 gruppe
Klipper is a 3d-Printer firmware. It combines the power of a general purpose computer with one or more micro-controllers.
OctoPrint provides a snappy web interface for controlling consumer 3D printers.
Moonraker is a Python 3 based web server that exposes APIs with which client applications may use to interact with Klipper.
Mainsail lightweight & responsive web interface for the Klipper 3D printer firmware.

Notes for the future

Calibrating PID settings is a wise thing to do everytime the environment around the printer changes 'significantly'.
