Basic Information:

Printer Model: Vcore 3.1
MCU / Printerboard: Octopus Pro+EBB42
klippy.log Not necessary

Fill out above information and in all cases attach your klippy.log file. Pasting your printer.cfg is not needed

Hi,

I’ve had some problem, I think with the extruder motor overheating, and one of the things I want to check is if the driver (TMC2206) is configured correctly.

Right now I have this configuration for the extruder driver

[tmc2209 extruder]
uart_pin: EBBCan: PA15
run_current: 0.60 # antes 0,40
stealthchop_threshold: 0
interpolate: True
sense_resistor: 0.11
driver_TBL: 0
driver_TOFF: 4
driver_HEND: 6
driver_HSTRT: 7

…

I have read that for the extruder motor it is advisable to put it in “spreadCycle” mode, but I am not sure how to do that if:

A)-Setting it to 0, just as I have it (stealthchop_threshold: 0)

either

B)- Erasing the line (stealthchop_threshold: 0)

C)-A nother way…

The truth is that the lines: driver_XXXX, I don’t know where they are from, I think I remember that I copied them from some configuration… They are fine, it has the Orbiter 2 motor, I think a Nema 14 LDO

Are ok?

Thx

This means you are already in spread cycle. Spread Cycle is also Klipper’s default.
For the Orbiter settings see Orbiter v2.0 – ORBITER PROJECTS

How do you know? :wink:

#stealthchop_threshold: 0
#   The velocity (in mm/s) to set the "stealthChop" threshold to. When
#   set, "stealthChop" mode will be enabled if the stepper motor
#   velocity is below this value. The default is 0, which disables
#   "stealthChop" mode.

To keep stealthChop it always on, set the value to 999999
