Klipper has a tool to assist with this. Then count the number of teeth on the stepper motor pulley. SET_STEPPER_ENABLED STEPPER=stepper_y ENABLE=0. This document is a reference for options available in the Klipper config file. It was like the tmc2209 had not been defined yet so it was confused when trying to use it in the endstop_pin definition. The rotation_distance is then calculated as: rotation_distance = <belt_pitch> * <number_of_teeth_on_pulley>. Can you please add this to the documentation as an example ? Klipper creates a "virtual serial port" via the "/tmp/printer" file, and it emulates a classic 3d-printer serial interface via that file. I made macros with manual stepper and X-axis stepper move at the same time then it worked, but not for two manual steppers at the same time. So, to invert the direction your X Axis stepper is going in, use the “!” character to change direction the “dir_pin” in the [stepper_x] statement commands the stepper to move like: [stepper_x] step_pin = PE2 dir_pin = !PB4 ### - Note the "!" Jan 29, 2023 · To invert the value of a pin, use the “!” character. Dec 28, 2019 · Manual steppers can only be moved one at a time. Klipper uses the hardware names for these pins - for example PA4. For certain applications it would be desireable to move two or more manual steppers at the same time. So, to invert the direction your X Axis stepper is going in, use the “!” character to change direction the “dir_pin” in the [stepper_x] statement commands the stepper to move like: [stepper_x] step_pin = PE2 dir_pin = !PB4 ### - Note the "!" 1. Configuration reference ¶. Maybe it's just me but it's a bit confusing configuration requires full name and command doesn't. Is there a specific reason you want to connect two motors to opposite ends of the same axis? Yes, you'll get more torque if your driver can deliver sufficient current, which would be shared between the two motors, but I would guess you'll add a whole load of additional mechanical issues. And it also works for other steppers? Like for X: SET_STEPPER_ENABLE STEPPER=stepper_x ENABLE=0. So, to invert the direction your X Axis stepper is going in, use the “!” character to change direction the “dir_pin” in the [stepper_x] statement commands the stepper to move like: [stepper_x] step_pin = PE2 dir_pin = !PB4 ### - Note the "!" Initial Startup Checks. If you are sure it is supposed to be 360 then look somewhere else, but I would lower that number EDIT: your first configuration for the [tmc2208] is right, rotation Jan 13, 2024 · Generally if you have a stepper motor that you want to be able to synchronize to an extruder you would use an extruder_stepper config section: Configuration reference - Klipper documentation. The descriptions in this document are formatted so that it is possible to cut-and-paste them into a printer config file. Although in practice, using SYNC=0 doesn’t seem to work at all. Most printers use a 2mm belt pitch (that is, each tooth on the belt is 2mm apart). It seems it waits roughly the time it would take for the full move when the move is actually over alrleady. However, when the drivers are in this mode, no special Klipper configuration is needed and the advanced Klipper features discussed in this document are not available. If yes, most probably firmware configurations of the motor current have no effect. front right screw must be turned clockwise 1 full turn and a quarter turn.

Klipper has several compelling features: High precision stepper movement. It is not a goal to support every possible G-Code command. [tool_name] is linked to #1 above. Edit: So I found an install manual for the CR-10 printer and followed those instructions. I will try the hardwire route but don't understand why this way will not work. This value # will be used if a MANUAL_STEPPER command does not specify an ACCEL # parameter. If you are using klipper you can put a carat () in front of the stepper pin in printer config to reverse it. works, i was expecting it to be the way i tried it. The Klipper PROBE_CALIBRATE tool can be used to obtain this value - it will run an automatic probe to measure the probe's Z trigger position and then start a manual probe to obtain the nozzle Z height. So, for example, 15 minutes is a quarter of a full turn. #accel: # Set the default acceleration (in mm/s^2) for the stepper. Locate the pin the white wire is connected to and note it down as “sensor pin. Extruder kinematics. To enable this feature include an exclude_object config section (also see the command reference and sample-macros. When I press home all the motors are turning in the good direction and detect properly the end stops. ) Unlike other 3D printer firmware options, a printer Jan 29, 2023 · To invert the value of a pin, use the “!” character. I'd also like to not have acceleration if possible, or have minimal otherwise. The default for the value for the endstop position is -0. image838×199 14. The proper way to do it is to set the direction in the firmware config file and reflash it. It is labeled as position_endstop and can be found in the [stepper_z] section of the configuration file. During this guide, it may be necessary to make changes to the Klipper config file. May 11, 2018 · SET_STEPPER_ENABLED STEPPER=stepper_x ENABLE=0. But MANUAL_STEPPER STOP_ON_ENDSTOP=1 takes it’s sweet time after the stop. A "normal" rotation distance for a bed slinger (aka Ender 3 style) would be 40 for XY axis steppers and 8 for the Z stepper, extruder stepper is also lower than 40 usually. The default is 5mm/s. Here is a macro I’m trying to implement: [gcode_macro STAND_UP] gcode: MANUAL_STEPPER STEPPER=leg_left MOVE=120 SYNC=0 MANUAL_STEPPER STEPPER=leg_right MOVE=120 SYNC=0 MANUAL_STEPPER Use the STEPPER_BUZZ command to verify the connectivity of each stepper motor.
