Klipper Settings for Kossel Clear

[Colin Trachte]

Hello All,

I have been partially successful getting Klipper to run on an Octopi raspbian image with a Kossel Clear. Thought my settings might be something of interest to the community. I could use some help as well, because prints are about half the size they should be. Manual moves are very slow compared to print speeds, need to know how to adjust that.

Step distances have been calibrated. At .00625 step distance, the carriages move 100mm when I command 100mm manual move. The motors are all moving in the correct directions. Homing works. I am using RAMPS with DRV8825 motor drivers, which have 32 microsteps instead of 16. I have the carbon fiber magnetic arms.

Thanks,

- Colin

#   NEXT extended g-code command to record the position at that

#   point. The default is false if a [probe] config section is present

#   and true otherwise.
