I’m sorry, but I don’t insist on anything.
Again, I am just following the “instructions” from Klipper documentation
As can be observed, the very first line says
These instructions assume the software will run on a Raspberry Pi computer in conjunction with OctoPrint
In fact, I tried to get away from OctoPrint by installing klipper, mainsail, fluidd, moonraker and pgcode, as mentioned in my first post.
I now totally reformatted the uSD card, removing the boot partition and all.
Copied only “klipper.bin” from the “home/[the name of my Pi]/klipper/out” folder onto the blank uSD card.
And renamed it so it’s different than the last name used for flashing (I increment a number behind klipper, right now I’m at klipper5).
The result of all this is still a dark lightly backlit screen!
It might be that klipper works, did ask here how I can check.
I used the recommended OctoPrint and it shows this:
A) is it typical that the screen of the Ender is dead?
B) how can I find out if the klipper FW for the Ender is working?
C) can I reinstall klipper, mainsail, fluidd, moonraker and pgcode via kiauh now or will it mess up all the stuff I installed thus far?
after installing the
GitHub - thelastWallE/OctoprintKlipperPlugin: A plugin for a better integration of Klipper
which you kindly recommended I can now see the firmware, which lead me to believe that the FW flash worked.
Considering this I dug deeper and now believe that the screen might not work due to having been flashed itself before diving into Klipper.
As mentioned, “I had already flashed it prior to all this with “MRISCOC Professional firmware” successfully”.
During that prior flash the sceen itself had to be flashed also.
Could it be that now the screen is not compatible with klipper (or whatever I installed here)?

So how do I change the display to finally get this klipper thing going?
I did the display FW tour already, opening it, inserting uSD card etc.
Thanks!
Personally, I think a display is not needed because the webinterfaces are much more powerful. For example, Orca Slicer even has a direct integration for them. You can control the entire printing process from this slicer. Of course, your personal preferences may be different.
Your log looks good. Seems you are ready to fine tune and start printing. You may want to check:
Thanks for those, but the screen has to work since as mentioned above, I need to make sure that the printer still functions as it was before.
My friend is a total un-geek, he just plays discjokey with his uSD cards.
So he would need the screen to navigate his project once he inserts his uSD card into Ender’s slot.
I’m a bit at loss here, so after all the issues and back and forth of the installation you say that the Ender display won’t work with this Klipper software??
The options you kindly pointed out are
buying yet another part, a display,
or wire the existing display to the Pi (?),
or compile something designed for a (touchscreen) which the Ender 3 V2 does not have?
Just to make sure, the Ender 3 V2 I work on has a (non-touch) DWIN display, “the original display unit, it supports all firmware functions”.
Unfortunately yes.
There are countless printer types and hardware combinations out there. Klipper supports most combinations, but not all.
Especially displays are a bit of a weak spot and Klipper focuses on different UI solutions and less these little displays.
You can always easily revert to Marlin. Just flash the board with this MRISCOC firmware and disconnect the RPi.
TBH, Klipper is about printing fast and at high quality, and definitively not about looking fancy. Personally, I prefer fast and high quality over anything else. YMMV.
what a bummer, days of trying and now this.
It would be really great from the Klipper team to tell people all these issues they have.
I read all over that getting Klipper to work is a big hassle, many gave up.
It’s really sad to waste people’s time with such a software.
Initially I was really impressed with the abilities, but what’s the point if it totally wrecks havoc on your system.
If I had known about all these issues I would not have touched it.
Really frustrated after all this.
So much time and enery wasted…
Sorry to leave you frustrated.
You are right, a Klipper setup is a bit more involved than flashing a precompiled Marlin binary. Nevertheless, this is rewarded with many benefits over Marlin (which I used myself at least over 8 years), like:
Higher speed
Better quality
Changing settings without recompiling the firmware
Powerful webinterfaces
It is like switching from Notepad to a full-fledged word processor. It has a learning curve, but the reward is great once you mastered it.
Although I really understand your point, with Klipper being an open source project, all development and support is done by unpaid volunteers (in contrast to a company like Creality, who earns a good deal of money with selling the printers and releasing some half baked Marlin with GPL violations).
So it might be a bit out of scope to expect that you get delivered a solution that respects all your personal needs on a silver plate.
