Fixing Layer shift and nozzle grinding prints

At Your Own Risk

The following requires editing the printer configuration files on the Nebula Pad. As these configuration files adjust how the printer hardware works, bad edits may break your hardware or cause other safety issues. Make sure to read the full process before starting and follow each step closely.

1. Open Fluid in your browser or Ocra slicer, for this tutorial will use the browser, but if you have Ocra slicer set up, skip to step 4.
2. Open your browser.
3. Type YOUR_PRINTER_IP:4408 for example 192.168.0.100:4408 and click enter.
4. Click on icon that look like "".
5. Find file named printer.cfg and open it.
6. When you see a lot of text in there, CTRL + F to open search function.
7. In search bar type [tmc2208 stepper_y]. It should take you to the exact text you typed, if not, use arrow keys to navigate down.
8. You should see something like this:

   [tmc2208 stepper_y]
   uart_pin:PB13
   interpolate: True
   run_current: 0.6
   sense_resistor: 0.150
   stealthchop_threshold: 0 
   

9. Now edit line run_current: 0.6 to run_current: 0.8

   [tmc2208 stepper_y]
   uart_pin:PB13
   interpolate: True
   run_current: 0.8
   sense_resistor: 0.150
   stealthchop_threshold: 0 
   

   
10. Now in search bar type [tmc2208 stepper_z], it should take you to something like this.

    [tmc2208 stepper_z]
    uart_pin: PB14
    interpolate: True
    run_current: 0.6
    stealthchop_threshold: 0
    sense_resistor: 0.150
    

11. Change the value of run_current: 0.6 to run_current: 0.8 like this:

    [tmc2208 stepper_z]
    uart_pin: PB14
    interpolate: True
    run_current: 0.8
    stealthchop_threshold: 0
    sense_resistor: 0.150
    

    
12. Click Save & Restart
