The Nozzle Wiper V3.4 - X/P Series

The Nozzle Wiper V3.4

I have designed this new nozzle wiper for my 8 X1C. The original wiper isn't effective and when I got my A1 I saw how great the A1 wiper was so I decided to adapt an A1 wiper to my X1C.

This is the third version, fixing each problem version by version. This solution cost me less than $1 and now my nozzle is always clean, which reduces defects on my prints.

I have tested the latest version 3.4 for over 1500 hours of printing without any problems, I printed mine with Bambulab PC as I use a lot of high end filament that requires an active heat chamber.

The A1 wiper is available in the official Bambulab store at an affordable price.

⚠️ Use a material that can handle the heat, like at least PETG.

⚠️ Use my print profile marked as designer to make sure you are using the latest version of this model.

INSTALLATION:

1. (Optional) Remove the original wiper by removing the screw holding it using the larger allen key.
2. Assemble both pieces by sliding the smaller one into the notch, it should be fully inserted, a small mark on the right side should be aligned.
3. Cut an A1 silicone wiper, counting to get 4 rows, and install it on top of the new wiper, I recommend removing the double sided tape and using CA glue.
4. Remove the two screws on the top of the purge chute - using the smaller Allen wrench.

5. If you have decided to keep the original wiper, you will want to push it to the front and left side when you insert the new wiper.
   Insert the part the back first and press the front to fit into the purge chute and screw the 2 screws back into place.
   
    

   

CUSTOM G-CODE (Optional - Advanced user)

1. In the slicer, open the printer profile.
2. Switch to the "Machine Gcode" tab and locate “Machine start G-code” area, click on the edit button next to it.
3. I recommend placing the custom g-code right after the nozzle rubs against the steel plate.
   In Bambu's current Gcode for the X1 machines, you can find this by scrolling until you see the line: 
   “;===== wipe nozzle end ===============================”.
4. Insert the additional code a few lines above,before the “M221 R; pop softend status” command.

UPDATES:

3.4: 2025-03-01  Latest 🎉

• 2 parts model, easier to print.
• Removable OEM wiper is optional.
• Optional custom G-CODE

3.3: 2024-11-09 

• Fixed printing problem with model.

3.2: 2024-09-08

• Added chamfer to provide more clearance for aftermarket build plate.

3.1: 2024-04-26

• Added more clearance (0.5mm) to the build plate due to a problem with the non-Bambulab plate touching the wipers.

3.0:  2024-04-20

• With the previous version, people had problems with mounting due to differences between printers and filament calibration. The print is now fixed with one or two screws from the purge chute. This makes it more stable on the purge chute.
• I changed some of the structural parts of this new version to make it stiffer and less prone to deformation when the chamber heats up.
• This new release fixes a purge issue after the first layer inspection (X1C) where the toolhead would purge on top of the wiper.
• I had a problem with the screw holding the original wiper, the screw didn't provide enough support, so I decided to design a new way of holding the wiper.

BENEFITS:

• No Brims
• Designed for FDM Printing
• Smooth Operation
• Clean nozzle
• Tight Fit
• Hold by screw
• Easy to build
