Two printers will always beat one printer. Upgrading your ender 3 will be a money pit if you want something that does same as last generations printers.
An designed enclosed printer will let you use ABS that is to my mind one of the best plastics I use.
I don’t know for Creality K1/K2 though.
That’s a great answer too.
Hi there Paf,
You are totally right, lack of power (cpu) on a Marlin firmware. When using klipper, the board doesn’t do any processing anymore. It becomes dumb and transfert the input signals to the pi and output signals to the motors etc…
A board not powerful enough for anything can do evrything under klipper if compatible. (some cpu was not compatible last time I checked 2 years ago, it may have changed). The awesome thing with klipper is that it can be compatible with the original motherboard and you can add resonance compensation just by plugging a pi. But that’s not OP problem as he needs a new board.
For me, Klipper had been a great discovery and I can’t think to go back simply due to the easy way of changing the config files compared to recompiling everything in Marlin.
Hahahaha, sorry about that.
The board you chose will limit what you can do due to memory space limitations or raw power.
The original ender 5 board didn’t had enough memory to activate auto bed leveling without removing other things.
In this world we have 3 firmware usable I know of:
The board you choose will limit the firmware you will use that will limit what you can do with it.
Take a look to what resonance compensation is by example. I’m not sure it’s available on Marlin due to lack of raw power of the boards.
But with kipper firmware offloaded to the pi, with a compatible board, you can unlock resonance compensation that gives a way better finish to your prints and easier config changes like Reprap (duet3d)
As you can see it’s a rabbit hole 😁
It depends what you want:
You are fine with the current options you had with the creality board, maybe activate auto-bed levelling Go the SKR way as other have mentionned
You want to get the most of your printer with Resonance Compensation (the next best thing for surface quality) Go check klipper I have it on all my machine. You’d need a board like @emilie mentions or a basic board + a full raspi (Zero 2 if no cam) Duet3D may be doing it too but I’m not knowledgeable on their solutions.
Start to spread into your friends/parents/kids place and send them virtual files to print :p
