Ultimate X1 / P1 Nozzle Wiper Over Engineered

Description

⚠️For .cn users, due to print profile out sync, please go to makerworld.com to download the latest version.⚠️

4 grams only. It is a PTFE bracket, using PTFE as a wiper.

The key to success is creating a well-shaped wiper, with good length to rub the nozzle. If you don't do it carefully, you won't succeed. So the problem is you and not the wiper model. (length of tube? The highest the best.)

Lower profile version is here if the extruder too low and hit the wiper bracket.

4x PTFE actively sweep 💩 out ! (whenever the nozzle hits the left wiper. See the action below.)

Upper PTFE is well above the nozzle level.

PTFE is virtually non-stick. No chance 💩 to hang on it.

Double PTFE V-cut wipers with optimal tilt angle effectively prevent poop from dragging out of the chute!

^^End of executive summary.

Printed in PETG or similar for heat resistance and good sweeping action flexibility.

Highlight features:

Effectively sweeps off the poop and wipe the nozzle.

Easy access to the chute for periodic or ad-hoc cleaning during printing.

First layer Lidar scan friendly. 😏

Bye bye 💩💩 Hardly stuck poop chute!

Wiper 360 (No PTFE insert yet. And it is also a 39mm cutting template).

PTFE cutting template 360. Good for startup. And you may need longer to achieve the best results.

Use template to create V-shape nozzle scraper and notched end insert.

(If you don't have any leftover PTFE, you can start with the minimal 1x 39mm and 1x20mm for the left wiper. Cut it from AMS for the time being.😏)

Notched end insert orientation. Longer/deeper side on the left hand side.

4x 39mm PTFE sticks sweep off poop effectively

The wiper itself is a template ~39mm

The reverse tilt arrangement allows for a good balance of purge volume space and also prevent poop from dragging out of the chute.

4x PTFE safeguard the top of the chute "flip plate" from getting 💩 hung up on it.

Base on my timelapse prints, prime tower seems no longer a must.

TIPS and troubleshooting:

⚠️⚠️⚠️Overtightening the screw will wash away the plastic threads of the chute unit.⚠️⚠️⚠️
Follow this link to remove the default nozzle wiper.
Printed in PETG for good sweeping action dynamics.
For new installations, be sure to perform a test run using manual XY control and monitor wiper action against the nozzle.
Spend effort creating a good V-shaped cuts and notched ends.
If the left wiper is too short, it won't create a sweeping action on the 4x PTFE, the nozzle won't clean, and poop will drag out (The first layer lidar scan is the most difficult task to complete😏).
If any wiper is too long, it will damage the hotend silicone boot and create a very noisy wiping action.
FYR, I used the longer template for the left side and the shorter template for the right side. Please report back if that's not the case.
If you're confused, watch the YouTube demo link again. Turn up the volume and feel action.😏
Strongly recommended to download OverEngineeredWiperV1_dryrun.txt, rename to .gcode and copy to the sd card to test and break in the wipers. (gcode start with 3 rounds slowly, pause 10s, 1000 rounds speedy)
Finally, test with the 2xCube print profile with AMS. Or try this multicolours Z-axis shield https://makerworld.com/en/models/773525 below.

Feedback:

Can it also be used on P1 series? All print profile updated. I think it should be good now.
I based this on my X1C. It may contain errors due to machine tolerances. Please notify me if there are any adjustments.
Durability. Is PETG not elastic enough or is it fatigue when sweeping?
