Klipper Firmware

Well...
I was thinking about moving to Klipper for a while. And now I got my TEVO Tarantula configured with it.

Klipper is new firmware, that is totally different from any other firmware by the way how it controls printer's kinematics.
You need Octoprint with Raspberry 3 or similar
You can read and get it here: https://github.com/KevinOConnor/klipper

There is new plugin in Octoprint for Klipper.

What is good:

• to change config you won't have to flash it into printer - just edit it in OctoKlipper plugin of OctoPI
• at same speed it can give better quality;
• it can achieve much higher speeds (you might need to make printer more sturdy). Before I used to print at 50-60 mm/s. First my print with Klipper I did at 80 mm/s. Second - at 110 mm/s. It has shown that I need to tension belts better. Also I will redo extruder bracket shorter and add the stiffening ribs to it. But overall it is OK for my purpose. 2 Hours instead of 5 is important! And definitely I can increase speed further.

What is no so good, though it is only for high speeds above 100 mm/s:

• You have to use highest filament temperature to extrude it faster;
• with PLA it is fine, you use fan. but with ABS you need to tune corner speed, and sometimes use fan (slightly).

Bed leveling is working fine. Same as mesh leveling.

In the config file there is a section for Bed Tilt leveling commented out, because I used Mesh leveling. You can use only one - ether ether.
Note that I specified number and coordinates of points for my large bed. You need to adjust that is yours is not 200x280.
Also, My Octoprint by some reason uses ttyUSB0. You will find it when you install Klipper in your OctoPi following instruction.

As for your printer additions/mods: the more weight you hang on cartridge and bed it the more wobble you introduce.
I might review some parts of my printer to make it stiffer and lighter.

Has anyone flashed a ffcp with klipper? Ive some how managed to burn out my mother board (unrelated) and finally got a new one. i know the chip is supported and Id really like to try klipper but im not sure of what pins are used for what. Any help would be greatly appreciated.

Hello,

Can you connect a z-probe to the raspberry pie and use Klipper to level your bed ?
