I recently noticed some skipping from the motor when printing PLA-CF a little faster than normal so i upped the current to 0. 0 hold_current: 0. I have never used klipper, and I'd like to give it a go. I normally run them at around 25 (mm/s) You driver_sgthrs values are pretty high (which means they can be overly sensitive), especially since you are running with 0. If the stepper is operated at different currents, then the effective real-world current shall be used, i. 800 hold_current: 0. 0 [tmc2209 extruder] uart_pin: PF2 run_current: 0.

It’s a very standard approach to wiring two unidirectional serial lines to a It is a good idea to review this document when upgrading the Klipper software. There are two dimension to the story: The correct current for the stepper. So, I made TMC CoolStep work and also made some tools to measure live driver values (similar to ADXL345). Follow this guide and become your own Vref calculator! Currents (run current, hold current, homing current if using a Klipper version that supports the latter) interpolate: true; The Klipper documentation recommends not using interpolation. Klipper uses RMS current as configuration values; Datasheets of the various stepper motors either give RMS or Peak current as rated current. Since the hold_current setting is a bit squishy, what sorts of things do you look for in the print quality or printer [tmc2209 extruder] uart_pin: PC11 #You want to double check this tx_pin: PC10 #You want to double check this uart_address: 3 #You want to double check this run_current: 0. 110 #driver_SGTHRS: 255 # 255 is the most sensitive value, 0 is the least sensitive stealthchop_threshold: 999999 # This will maker the steppes more silent and smooth [tmc2209 stepper_y] uart_pin: PC9 diag_pin: PB0 run Great Prints?

Since I just # after running "make", copy the generated "out/klipper. Next, continually decrease the sensitivity of the VALUE setting and run the SET_TMC_FIELD G28 X0 Because the Z axis movement is quantized by the stepper motor, the values returned by BL Touch cannot be continuous and are also quantized. It was very bad at 0. I then moved the kiuah directory back. I replaced the drivers with MKS TMC2209. The calibration process is: For TMC2209, start with SET_TMC_FIELD FIELD=SGTHRS STEPPER=stepper_x VALUE=255 in the console. 11 Ohm you end up at a peak current of ~2. Next, continually decrease the sensitivity of the VALUE setting and run the SET_TMC_FIELD G28 X0 I have a core-XY printer (Sapphire plus 5) using MKS robin nano board, and MKS TMC2209 steppers I have klipper on it, and using UART mode for the drivers !PE4 microsteps: 16 rotation_distance: 40 endstop_pin: PA15 position_endstop: 0 position_max: 235 homing_speed: 50 [tmc2209 stepper_x] uart_pin: PD5 run_current: 0. 3 klippy. log of klipper, I examine it and I see that: “[tmc2209 extruder] run_current = 0.

Klipper docs for reference: My problem is either with the wiring, or the run/hold current values I think? (When I tried to turn the extruder, with no filament in there, the motor just made a horrible noise. Datasheets of the various stepper motors either give RMS or Peak current as rated current. The correct current for the stepper. cfg (3. 60 stealthchop_threshold: 999999. 8A versions) hold_current: 0. 14A, you are running your hardware effectively outside its specification by a factor of 17. 650 to 1. Next, continually decrease the sensitivity of the VALUE setting and run the SET_TMC_FIELD G28 X0 Klipper github issue. I then ran the install script. 500 stealthchop_threshold: 250 [tmc2209 stepper_z] uart_pin: P1. cfg I wanted a fresh install so I moved all files to a directory called old. 5: Basic Information: Anycubic Mega X TrigorillaV0. Determining hold_current. 4 run_current: 0. 4 nozzle Then issue a G28 X0 command and verify the axis does not move at all or quickly stops moving. It was better at 0. 9 degree steppers, which gives me a 0. The printer Looking at your configuration, you have set the run_current of your steppers way too low. 700 %} {% set driver_config = printer. Sometimes there is a recommendation for say an extruder. stealthchop would make much of a difference (other than being noisy as heck). 410 for your X, Y, and Z steppers and delete the hold_current while you're at it. I'm using an ardunio Nano and the Bigtreetech 2209 Stepper driver to control a Nema 17 stepper. 138 hold_current = 0. 3 config as a baseline. For example TMC2209 drivers are rated to 2a RMS, but I would generally not exceed 1. Grinding noises when stealthchop is on. run_current %} # Set current for sensorless homing SET_TMC_CURRENT Then issue a G28 X0 command and verify the axis does not move at all or quickly stops moving. All Hi @kakou-fr,. One of these pins is “DIAG” and if it is missing, then you will not be able to get sensorless homing working. Old Printer? Cheap Printer? New Printer? Bad Prints? Great Prints? Klipper can help you and your machine produce beautiful prints at a fraction of the time. 5: 35320: November 6, 2021 TMC2226 UART Control Rotation Distance Issue. Ideally you want to run as much current as you can without heating up the motor too much. 7 Host / SBC Raspberry Pi 4B klippy. I just installed an SKR 1. 0 query I dont know if I should ask this here or in toolhead and extruders but since its mostly klipper config so posting here. # The "make flash" command does not work on the MKS Robin. However, the official Klipper documentation warns against changing currents or modes on-the-fly as it can introduce positioning errors, reduce torque, or even lead to increased motor heating. It may not be perfect but is a starting point. Operating Current Setting: This is a percentage of operating load you wish to run the motor at (Value from 0-100 as an integer). I removed klipper, moonraker, etc then installed them again using Kiuah. Motor is cool to the touch (maybe 80F). How are calculated the “hold_current” and “run_current” for TMC2209 ? This “Calculating Driver Current Settings” howto from the Voron site reinforces what @Sineos said, mainly regarding the run_current calculation. 860 stealthchop_threshold: 0 interpolate: False sense_resistor: 0. 800 stealthchop Then issue a G28 X0 command and verify the axis does not move at all or quickly stops moving. I also had MKS. 1 rotation_distance: 40 endstop_pin: P1. Klipper Hold_current and run_current -- TMC2209. The default is True. Dazu gehört step_distance . Almost all works fine except very first move of steppers motors. 800 diag_pin: interpolate: False [tmc2209 stepper_y] uart_pin: PD3 run_current: 0. 4A and see if that resolves your issue. But 2Amps is definitely too high. [tmc2209 stepper_z1] uart_pin: PB5 run_current: 0. Recently, Klipper docs have started to recommend against using a separate hold_current. This is not an official Klipper support channel and poorly moderated so ymmv. ORIG: run_current: 0. 3480291 Just in case it can help, here is my config for the above. You can set run_current basically based on your motor temps, and torquer/speed requirements. org [tmc2209 stepper_y] uart_pin: PD11 run_current: 1. log I have a Kobra (standard) that I installed and SKR 3 EZ on. The log file has been engineered to answer common questions the Klipper developers have about the software and its environment (software version, hardware type, configuration, event timing, and hundreds of other questions). 19 dir_pin: P0 In regards to the 1k resistor between the TX and RX line, this is a current sink that prevents the TX line from being back driven when the TMC2209 is driving the PDN_UART line. settings['tmc2209 stepper_x'] %} {% set RUN_CUR = driver_config. More often peak current to my knowledge (often unclear from the specs) Current as Peak Current: Multiply by 0. 2 MB) canFly. 02 ;pressure advance – to be calibrated M207 S1. I've just upgraded my printer to have an SKR3. Next, continually decrease the sensitivity of the VALUE setting and run the SET_TMC_FIELD G28 X0 I did some research.
