If you update your firmware, your EEPROM will overwrite any changes your firmware might have tried to make. Step 8 Extruder Steps-per-mm Tune To get a more exact value for your E-steps-per-mm, measure the exact amount of filament that is pushed out of your extruder. For this example, I’m using a Rostock Max by SeeMeCNC and the field is “Extr1 Steps/MM”. One of them is it does not natively support separate steps per mm values for left and right extruders. We need to do some basic math to calculate the proper steps/mm for your machine. h line: //#define Y_MAX_PIN 15 File: Marlin_main. module-name. 8degree Anet steppers PID bed calibration, enable PIDTEMPBED in marlin, disable BED_LIMIT_Switching Disable Thermal Runaway for the bed only for PID autotune to work. Proceed to the next step. Just wanna clarify the G92 Exx,the E stands for Extruder, there will also be an X,Y and Z. Configurator tools for MarlinKimbra firmware. I may need to tweak the firmware settings slightly but so far so good. As the new extruder uses a gear reduction to create a high extrusion resolution and high torque the E-step value needs to be changed. After I built the X-Carve and got a few test cuts in, I found it odd there was no tuning step. Also to get steps per mm right for A4988 you will need to change Configuration. Each line may only contain one G-code (or Mcode) with included variables. steps/unit = motor_steps_per_rev * driver_microstep /1. I told jagowilson of my intentions and he said Marlin doesn't work right when steps/mm exceed 100,000. A lot of 3d printers use a M8 threaded rod on the z-axis. 100mm of fresh filament is extruded from the printer interface with the driven filament length being measured for length accuracy. To calculate the Extruder Calibration steps per mm from the extrusion length you can use this equation; steps/mm × 100 mm = X then X / extruded distance = new steps/mm value. Load filament into your extruder, just until it is gripped by the drive shaft (you can't pull it out without moving the large gear turning). Marlin - File:Marlin v1902. With the next line you have to calibrate (roughly) the axis by setting the necessary steps per unit (Marlin uses [mm]). 19 in the printer firmware. One more thing if I use the correct DEFAULT_AXIS_STEPS_PER_UNIT { 79. 802 steps/mm * 40 mm/sec = 32080 steps/sec. Generic marlin users are not affected because MK8 like extruder's steps per mm value around 95. Extruder is calibrated in the firmware with the correct steps per mm of filament. After installing the Bondtech firmware and performing a factory restart per their instructions, Bondtech states that this will properly set the extruder steps/unit. In Marlin, you set the maximum.
