One minute nozzle cleaning solution

thingiverse

Hi! This is my go-to solution for a quick and effective nozzle cleaning before each print. I got inspired by the Marlin software, which has a "nozzle cleaning" part. It was initially intended to be a temporary fix since I came across other interesting cleaning options on Thingiverse. Surprisingly, my makeshift solution works so well that I've stuck with it. It's been a month of printing with the same worn-out sponge as shown in the photo without any issues. You'll need a small piece of temperature-resistant sponge - I used a small cut from a welding station sponge, which measures 2x3cm. Attach it to the corner of your bed using the standard clip provided with your printer. Add "special" commands to your slicer's startup sequence (i.e. Cura--Settings--Printer--Manage Printers--Machine Settings--Start G-Code window). It should be after bed leveling, just before printing. You can place it at the very end of the start G-code. That's it! Reminders: - Soaking the sponge might seem like a better idea, but it's actually not. Hot filament sticks to the dry sponge and stays there, which doesn't happen when it's wet and cold. - Adapt the code to your bed dimensions. Perform tests without the sponge and clip to prevent collisions. Alternatively, change "G0 Z3" to "G0 Z15" for coordinate testing. After success, go back to "G0 Z3," which is 3mm above the bed. Search for "welding cleaning sponge." It's thin (about 2mm) but expands to 5mm after soaking, making it suitable for this hack. Use it after drying. Code to add: G0 E5; extrude some G0 X190 Y13 F3000; move to the corner G0 Z3; go down G0 X220 F5000; fast move G0 X200 F5000; fast move G0 X220 F5000; fast move G0 Y30 F5000; fast move G0 Z10; go up G92 E0; reset extruder Feel free to improve the code for even better results. I'd be happy to update my printer with your tested suggestions. Cheers! Happy printing! Happy New Year! https://youtu.be/h54-njedq6U
