I don’t have any endstops, and klipper refuses to work w/o endstop pins specified, so i tried to use my TMC2660’s stallguard instead as specified in the configuration documentation and examples. up to 1. Its continuous drive current is 2A and peak current is 2. " Stepper power consumption is close to negligible. (which doesn't work/load in this state) [stepper_x] step_pin: P2. 29 endstop_pin: tmc2209_stepper_x:virtual_endstop I've had this working before for X and Y so I'm wondering if there's a bug with using the probe:virtual_endstop with a tmc_2209_stepper_z:virtual_endstop in the probe section. You put the two plugs into "SERVOS" and "PROBE" (you might have to switch a pin or two in the header, check the wiring). 27 endstop_pin: tmc2209_stepper_z:virtual_endstop homing_retract_dist: 0 position_endstop: 0. Everything will work fine for a few prints, and then the y-axis stops homing. What am i Dec 8, 2023 · The TMC2226 and TMC2209 are advanced motor driver ICs for two-phase stepper motors. Sensorless homing makes use of the stallguard feature built into the TMC2209 stepper drivers plugged into the Manta M8P for the A & B motors that drive the toolhead on X & Y. 0 driver. I have the new SKR 1. The appropriate "DIAG" or "SG_TST" pin of TMC driver connected to the micro-controller. Motor interface type = 1 for AccelStepper. [stepper_x] step_pin: PE9 dir_pin: PF1 enable_pin: !PF2 microsteps: 16 rotation_distance: 40 Feb 5, 2022 · diag_pin:PC1 microsteps: 16 rotation_distance: 40 endstop_pin: tmc2209_stepper_y:virtual_endstop position_endstop: 0 position_max: 235 homing_speed: 20 homing_retract_dist:0 [tmc2209 stepper_y] uart_pin: PC11 tx_pin: PC10 uart_address: 2 run_current: 0. I'll have to check if there will be a potential short in any bend direction. The # defaults for each parameter are next to the parameter name in the # above list. 4 board. I've gone through the sensorless setup instructions with a Sep 3, 2021 · The TMC2209 is an ultra-silent motor driver IC for two-phase stepper motors. 4 Turbo / TMC2209 homing. BTT Octopus v1. To use this config, the firmware should be compiled for the # LPC1768 or LPC1769(Turbo). It moves a bit back and forth and that's it. 1 #Klipper /Moonraker/Mainsail installed with KIAUH script on Raspberry Pi 4 #Yann Vautrin 2022. Over UART, I can detect a stall! However, I want to be much more responsive and respond over the DIAG pin, which is supposed to go HIGH on stall. TRINAMICs sophisticated StealthChop2 chopper ensures noiseless operation,maximum efficiency and best motor torque. Iphase. 900 diag_pin: [tmc2209 stepper_y] uart_pin: PD3 run_current: 0. Jul 24, 2020 · Here is a simple code to get TMC2209 working with basic functionalities. 500 hold_current: 0. TMC2209 pinning is compatible with a number of legacy drivers as well as with the TMC2208. This means that the end stop pin is effectively tied to ground just like when the end stop switch is triggered. 4 Turbo and installed the TMC2209 Drivers. ①一般的TMC2209.
