Core One L Nozzle Wiper Bar

Nozzle wiping solution for the Core One L.

8/23/26: Added version which uses (2) M3 nuts instead of heat-set inserts. Push the nuts into the hex holes on top and screw from the bottom like before. Slightly longer bolt may be needed.

Will need the following to install it:

• 2) M3 x D5 x L4 Heat set inserts

  • I could make one that uses a nut on the topside instead if anyone is interested.

• (2) M3x6 screws

• A1/A2L Nozzle Wiper (https://us.store.bambulab.com/products/heatbed-nozzle-wiper-a1-a2l)

• (Optional, maybe), thin double sided tape, this is what I used (https://www.amazon.com/dp/B0CRRFHKQC)

1. Heat set inserts are installed on the bottom side in the two holes.

2. Double sided tape can be applied to the bottom of the wiper pad before installing to ensure it holds (I used the tape and have had no issues after a few hundred print hours, havent tested with just the stock adhesive.)

3. Align the bar as seen in the pictures, use M3x6 screws from the bottom in the holes of the build plate mounts to hold the bar in place.

4. Installation done.

I used this website (https://core-one-l-support.wiper-pathgen.pages.dev/) to generate my own path. Below is a video of my current wiping routine and gcode for it, but I would recommend making your own using the website, it will generate a test file that runs it much slower than normal for safe testing.
