Sonic Pad has Klipper which uses rotation_distance, you have to go into the printer. in Klipper there's no such thing as e-steps. Extruder¶ It's possible to obtain an initial rotation distance for extruders by measuring the diameter of the "hobbed bolt" that pushes the filament and using the following formula: rotation_distance = <diameter> * 3. 683 nozz Jan 17, 2023 · Basic Information: Printer Model: ender 3 v2 with an sprite pro extruder MCU / Printerboard: STM 32-bit board (4. 522 # 主动带轮周长mm So, for example, an M6 metric rod has a rotation distance of 1 and an M8 rod has a rotation distance of 1. Here you will find all of the files for the Galileo 2 projects, including a Voron Stealthburner drop-in Extruder (G2E), Z-Drives (G2Z) for V2-style printers (including V2, Micron, etc. 8 degree motor. Measure how much filament was actually extruded. 395 Le stampanti più vecchie con "barre filettate" hanno un solo "filo" sulla vite di comando e quindi la rotation distance è il passo della vite. gear_ratio: 50:17 After the upgrade I changed this value to 50:10 Did a save_config and restart. cfg file in the "Extruder" section: rotation_distance: 22. For Klipper users rotation_distance = full_steps_per_rotation * microsteps / steps_per_mmrotation_distance = 200 * 16 / 415 rotation_distance = 7. Apparently, need to create something like heater_fan. 683. When I used Marlin for my printer. Jan 13, 2023 · Only tested on klipper firmware: [extruder] rotation_distance: 53. This is crucial for accurate printing as it ensures correct Nov 7, 2023 · G’day! I wanted to share my Macro and configuration for a Mixing Hotend, allowing any mix between 2 extruders. The E-Steps were 415. 7 version print board. 17 gear_ratio: `44:14, 37:17` Логика работы концевика в Klipper следующая: при I'm trying to calculate the rotation_distance value for my Klipper printer. 0 Host / SBC: Bigtree CB1 v2 klippy. 5:1 to my config my extruder is putting out way too much. 925 This heavily depends on the dual gears itself as not all of them are same. Dec 16, 2024 · Basic Information: Printer Model: Ender 3 pro with rail mod on X and dual Z MCU / Printerboard: Bigtree MANTA M8P V2. I understand the cfg file isn’t plug and play but I’m having trouble understanding it all together. I've tested and adjusted my rotation distance but when running SuperSlicers flowrate test I'm finding the +20% flowrate to be producing the best quality print. 8 degree stepper. Older printers with "threaded rods" have only one "thread" on the lead screw and thus the rotation distance is the pitch of the screw. 14 So, for example, an M6 metric rod has a rotation distance of 1 and an M8 rod has a rotation distance of 1. 0 #===== # Extruder Z #===== [extruder] max_extrude_only_distance: 1000. 71 nozzle_diameter: 0. By using something like this: and measuring the steps using a micrometer, I’ve consistently found that the calculated value Sep 26, 2023 · I am attempting to calibrate the XYZ steps on my CR10S Pro V2. klipper3d. cfg). How does this translate to rotation distance? Would this mean that it is a 0. 7 This is set in your [extruder] section in your cfg in Klipper rotation_distance: 5. xx #define nozzle diameter Jan 13, 2021 · BIQU H2 V2S Dual Gear Extruder Upgrade H2 Extruder 3D Printer Direct Extruder 1. cfg fine the section for the extruder , the Sprite is 424. 14 Oct 28, 2023 · 3D Printing with Klipper, Setting Rotation DistanceKlipper is a high-performance 3D printer firmware that offers many advantages over traditional firmware su Nov 2, 2023 · 3. It doesn't matter if you use the one labeled for the stepper or not. 14 Sep 26, 2021 · To get the rotation distance that Klipper uses, we will need another formula: rotation_distance = full_steps_per_rotation * microsteps / new_e_steps. Finally upgraded to the Sprite Extruder Pro direct drive kit and decided to also upgrade from Marlin to Klipper at the same time, using a Pi4 4gb. In case the main drive gear tooth is not aligned with the filament exit guide, you may adjust its position by loosening the M3 fixing screw. ), and a Standalone Extruder (G2SA) with mounting options for Orbiter-2. 750 max_extrude_only_distance: 500 max_extrude_only_velocity: 120 I am running Klipper, and just installed a Micro Swiss NG direct drive extruder on my Ender 6. 7. 24 max_temp: 260.
