Had this noise when the current was set too high, but on these 2209s I’ve tried 0. e. This is not an official Klipper support channel and poorly moderated so ymmv. General Discussion. If you need more Experiment with different motor currents and test how they affect your maximum speeds/accels. (I don’t know if there is a difference between BTT TMC2209 and MKS TMC2209. The drivers do some black magic aka By default, Klipper places the TMC drivers in "spreadcycle" mode. cfg. ADMIN MOD Visualizing TMC2209 run current/load in stealthchop If the stepper is operated at different currents, then the effective real-world current shall be used, i. 6 enable_pin: !P2. The tmc2130, tmc2208, tmc2209, and tmc2660 run_current calculation code has changed. Klipper defines the RMS current unlike reprap where the max current is set, I currently run at 1. 000 and it always makes the noise when stealthchop is on. It has been found that the switch between run_current and hold_current has a negative impact on precision; Matching TMC driver. Great Prints? Klipper can help you and your machine produce beautiful prints at a fraction of the time. 110 #stealthchop [tmc2209 stepper_x] uart_pin: PB8 diag_pin: PC4 run_current: 0. 8 run_current: 1. Start with the most sensitive value for the StallGuard threshold based on It is a good idea to review this document when upgrading the Klipper software. Then issue a G28 X0 command and verify the axis does not move at all or quickly stops moving. 150 uart_address: 3 driver_SGTHRS: 81 diag_pin: PA5 I did some research. I’ve set up StallGuard on four printers now and I’ve never needed a value above 75 for driver_sgthrs. Determining hold_current. However, when the drivers are in this mode, no special See the installation document for information on setting up Klipper and choosing an initial config file. 707 to get RMS and then by 0. This extension calculates good values for most registers of TMC stepper motor drivers, given the motor's datasheet This document provides information on using Trinamic stepper motor drivers in SPI/UART mode on Klipper. From there I edited and change some of the values accordingly. 707” 02- I open the “printer. 8 uart_address: 0 [tmc2209 stepper_y] uart_pin: PA13 run_current: 0. Klipper can also use Trinamic drivers in their "standalone mode". I also had MKS. So I changed the run_current for X This # parameter must be provided. This is where I got some weird behaviour when setting the run_current in Klipper, if I set (taking the x motor as an example): [tmc2209 stepper_x] uart_pin: PB8 # diag_pin: PC4 run_current: 0. However, it is no longer recommended to specify a hold_current for most motors. Motor is cool to the touch (maybe 80F). This new configuration should be more accurate, but it may invalidate previous tmc driver tuning. Sometimes there is a recommendation for say an extruder. [stepper_x] microsteps: 16 step_pin: P2. And you can disable interpolation of microsteps and set it to 128 or 256. Finding the right StallGuard threshold . How do I set up tmc2209 uart in the klipper? #3686. 800 diag_pin: interpolate The correct current for the stepper. 750 hold_current: 0. I have PE0 run_current: 0. 14A, you are running your hardware effectively outside its specification by a factor of 17. log of klipper, I examine it and I see that: “[tmc2209 extruder] run_current = 0. 707 to determine the maximum current in RMS. 85 as safety margin Run_current / Stealthchop help. 800 interpolate: True hold_current: 0. Recently, Klipper docs have started to recommend against using a separate hold_current. If the axis does not stop, then issue an M112 to halt the printer - something is not correct with the diag/sg_tst pin wiring or configuration and it must be corrected before continuing. 110 stealthchop_threshold: 5000 [heater_bed] heater_pin: PA0 sensor_type: EPCOS 100K B57560G104F Great Prints?

Klipper can help you and your machine produce beautiful prints at a fraction of the time. Fiddle a little with current settings, I basically run mine at the minimum current and they work fine, even at 120mm/s @ 10k acceleration (belts and nuts were the major problem). 8 uart_address: 1 [tmc2209 stepper_z] uart_pin: PA13 run_current: 0. 1 rotation_distance: 40 endstop_pin: P1. 8A run_current. 8 uart_address: 2 [tmc2209 extruder] uart_pin: Klipper configuration for SKR 1. settings['tmc2209 stepper_x'] %} {% set RUN_CUR = driver_config. 4A) you are left with a range of not even 6% After a recent upgrade of my SV06 to Klipper I noticed that the stepper X & Y motors are running hotter than normal. ) When I set the driver_sgthrs value to 70, it started working. TMC2209 max out at 1720ma (based on its internal current reporting). 4A; If you now limit the actual current to a peak value of 0. 01- Find out the current to which they are configured, for this in Mainsail, I download the *. 4 turbo + TMC2209 + klipper . HOLDCURRENT is applicable only to the tmc2130, tmc2208, tmc2209 and tmc5160. 800 stealthchop A couple of things jump out at me: Your homing_speed (100 for x, 75 for y) is high. Thank you in advance. 860 stealthchop_threshold: 0 interpolate: False sense_resistor: 0. Many config options require the name of a micro-controller pin. 4 PRO + 4x TMC2209 UART - printer. More often peak current to my knowledge (often unclear from the specs) Current as Peak Current: Multiply by 0. For some run_current settings the drivers may now be configured differently. 3 + 4x TMC2209 running with Klipper and hope you could give me some help. 19 dir_pin: P0 Klipper github issue. It’s a very standard approach to wiring two What's the max current I can get through one driver on the skr mini e3 v3? I would like to run two stepper motors from one cable and need to know Hey I just read on the Voron build page that the TMC2209 drivers max current is 1. Multiply the peak current by 0. {% set driver_config = printer. configfile. Calculating Currents - To calculate the maximum Klipper current settings for a given stepper, follow this process: Look up the specifications for the stepper motor and locate the peak current limits of the motor. About two thirds down the page. cfg, until I find that the line [tmc2209 extruder] run Then issue a G28 X0 command and verify the axis does not move at all or quickly stops moving. UPDATE: my setup was a success. Ideally you want to run as much current as you can without heating up the motor too much. 6 sense_resistor: 0. 29 position_endstop: 300 position_max: 310 homing_speed: 50 [tmc2209 stepper_x] uart_pin: P1. 580 stealthchop_threshold: 0 [tmc2209 stepper_z] uart_pin: PD15 run_current: 0. If you created this issue and no longer consider it open, then please login to github and PA13 run_current: 0. Klipper uses the hardware names for these pins - for example PA4. For TMC2130/TMC2660/TMC5160, use SET_TMC_FIELD FIELD=SGT STEPPER=stepper_x VALUE=-64 instead. cfg” file, I examine the configuration files that are included in printer. 650 to 1. There were differences between TMC2209 and EZ2209 about diag. Or to put it differently: From a regulation range of 100% (=2. [tmc2209 stepper_x] CR10S + SKR 1. I replaced the drivers with MKS TMC2209. ORIG: run_current: 0. I am still tuning my run_current on my XY and E motor as they get quite hot. Grinding noises when stealthchop is on. mjoconr October 26, 2021, 11:30pm 2. Klipper current settings are based on Klipper extension for automatic configuration and tuning of TMC drivers. Next, continually decrease the sensitivity of the VALUE setting and run the SET_TMC_FIELD G28 X0 Klipper configuration for SKR 1. 27 Contribute to Klipper3d/klipper development by creating an account on GitHub. I have a tarantula pro (the orange model) with very little 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. Set the hold to around 25 percent. For example, a First step, remove or increase Hold Current and stealthchop_threshold. Check Klipper out on discord, discourse, or Klipper3d. Next, continually decrease the sensitivity of the VALUE setting and run the SET_TMC_FIELD G28 X0 Based on the documentation I have to adjust the run_current in Klipper to have the EZ2209 driver limit the current to the steppers. 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 SET_TMC_CURRENT STEPPER=<name> CURRENT=<amps> HOLDCURRENT=<amps>: This will adjust the run and hold currents of the TMC driver. 5 stealthchop_threshold: 0 Motor2_1 [stepper_z] step Dear Community I can’t get my SKR v1. 800 hold_current: 0. Klipper's run_current Given my understanding is correct, this brings me to the point where the TMC5160 are a complete design flaw for common 3D printers. Video is with it off and on. 6A and its been that way for about a year. A good rule of thumb is to not exceed 70% of the rated current as absolute max. It is recommended to always use "spreadcycle" mode (by not specifyingstealthchop_threshold) or to always use "stealthchop" mode (bysetting stealthchop_th The maximum Klipper RUN current settings can be calculated via the following steps: Use the peak current limit from the stepper specifications sheet for the stepper motor. 7A and its still pretty cool. 2 dir_pin: P2. A stallGuard capable TMC stepper driver (tmc2130, tmc2209, tmc2660, or tmc5160). I switched from Marlin to Klipper recently. 4a RMS. You can set run_current basically based on your motor temps, and torquer/speed requirements. It is a good idea to review this document when upgrading the Klipper software. 4A, so about 70% of what the motor can handle Reply reply Durahl • So basically, using the BTT TMC2209 2A Spec calculated to Run Current From the Voron Docs. Hello all! So I'm fighting this setup already 3rd day and need some help. This is the maximum run This # parameter must be provided. I recently noticed some skipping from the motor when printing PLA-CF a little faster than normal so i upped the current to 0. cfg You should start off with a more conservative run_current. 11 Ohm you end up at a peak current of ~2. 5 sense_resistor: 0. First and foremost, I set it up to use communication via usb cable and in klipper I have following line: [tmc2209 stepper_z] uart_pin: P1. org [tmc2209 stepper_y] uart_pin: PD11 run_current: 1.
