ANET A8 Nozzle Filament Wiper - Cleaner - Updated

thingiverse

UPDATE This now includes three different versions: The original, V2 and V3. V3 is taller and wider than the original, while V2 has dimensions between those of the original and V3. Both V3 and V2 make it easier to install the wiper blade. V2 is called 'slightly taller - slightly wider'. The height and width of this device depend on how compressed you make the springs on the heated bed, which will obviously change the bed's height. I've also added a couple of lines of g-code. DESCRIPTION So I've been thinking about creating a way to reliably clean my extruder's nozzle for some time now. Well, this works well for me. It uses the rubber part from a car window screen wiper. I've looked at three different types (cheap ones), and they all seem to have the same profile, so hopefully yours will fit. https://youtu.be/Y2JuGVRIpto Slide the rubber into the tapered end of the 3D printed part. Attach the part to the lower section (non-heated) of your heated bed by pushing it on (no screws required!). Your G-Code may need some adjustment, but the code below just moves the head to the front of the wiper, moves back slowly to clean it, lifts up, and moves to do it again. It does this three times, then just moves away to continue as normal. The video isn't that clear, but hopefully gives you an idea of what's going on. ; ********* Cleaning Code ********* G1 X185 F4000 G1 Y-13 F4000 G1 Z1 G1 E3 F100; PURGE NOZZLE G1 Y0 F100 G1 Z8 F200 G1 Y-13 F4000 G1 X191 G1 Z1 F100 G1 Y0 F100 G1 Z8 F200 G1 Y-13 F4000 G1 X196 G1 Z1 F100 G1 Y0 F100 G1 Z8 F200 G1 Y50 F3000; Move out of the way of wiper G;; 1 X10 Y10 F3000; BACK TO 'NEAR' FRONT LEFT G92 E0; ZERO EXTRUDER ; *************************
