About this 3D model

I update, revise and improve my design for my fixes very often. Please only use my Print Profile (Labelled as Designer or SPStudio) to ensure this fix is updated & work well. Profile with Non-Designer tags may be of poor functionality or non updated model. Click on Like if this model helped you in some way. It is very important and will help increase the exposure of this design to more people who might need it. Cheers! This will be my final Ams internal fix as i believe there is no bettor way to fix it internally anymore. Thank you so much for your support. Announcement New and Improved V2 Versions for the Ams Buffer Fix Before Buffer and After Buffer have just been released. Do check them out in my profile to see what are the improvement. Thank you for your continuous support. Introduction Failed to pull back filament error can be caused by multiple different variables & factors. This is a part of an series of Ams fixes that i have designed which can complement each other when used together. I do suggest you install all my fixes together for the 0ptimal effect to help your filament travel properly across the entire system which in turn can help improve, reduce or remove any potential Ams errors. I have grouped all fixes into their respective Collection for ease of searching what to install. V2 Collection are improvements done on the shortcoming of V1 Collection. Feel free to try V2 Collection and if it doesn't work properly then you can try the V1 Collection . You can easily find each of the Collection by clicking on the Collections tab on my profile. Unfortunately there isn't a single fix that can 100% work for everyone. What works for others, may not work for you but my fixes is definately a great place to start and have worked for majority of the users. My fixes are precisely measured then modelled. A Proper Fix would have the highest chance to reduce or solve the error. If you are too bored to read the entire lengthy write up explaining the need for this fix, here is the TL:DR. What is this? Ams Filament Pull Back Fix V2 Upgraded is a total revamp design of the hugely successful previous model for correcting the internal Ptfe tubes angle inside the Ams and maintain a straight Ptfe feeding into the Ams motor to reduce friction and pressure. Important Note: This new design is used to replace the older version. You can choose to use any of the version or try 1 then if it doesn't work very well then try the other one, but please DO NOT use both new and old model together. It will make things worse. Main difference with the previous model Ams Fix Failed To Pull Back Filament Error Completely New Design, even accurately designed to solve the problem compared to the original version. Will NOT affect your warranty as its reversible. Even well supported by the new screws design comparing to my previous fix or other similar clones trying to do a lookalike workalike. Precise measurement for reduced friction of filament moving through Helps reduce the internal Ptfe wear and tear Fix is now much closer in distance to the root of the problem. Ensuring nearly ZERO possibility or chances of the tube flexing near the entry point of the Ams internal filament hub causing that misalignment that might cause an error to pop up. Angle of the entry for the Ptfe into the Ams internal Filament have been re-optimised once again.. ez to install, just unscrew the 2 screws at the Ams internal Filament Hub and put in the fix then put back the screws. As the fix supporting the Ptfe is now right outside the entry of the Ams internal filament hub , possibility of failure to fix the problem because of bent or misshaped tube is now greatly reduced. This fix have been tested for on 1 X1C, 1 P1P and 2 P1S for about 94800 retractions so far as of this listing. Please ignore the silver screw i used as seen in the install video, just use the same original 2 black screws from your internal Ams filament hub. In order to make and design and measure this fix, i rounded my own screw threads after assembling and disassembling 50 times for variations i tested against height, angle and thickness. Please follow the installation video closely to ensure you are installing it correctly. Failure to follow will affect how well the fix will work. Video at end of page. Who needs this fix? 1) Constantly having errors like Failed To Pull Out Filament and similar related 2) The Ams motor sounds like struggling when move filament in and out of the Ams to the Extruder, like a lot of friction when moving. 3) Ams cannot load or unloading properly. (Not including Spool being too light or a break of filament in the Ams) 4) Having a constant struggle on any of your Ams slots, people complained about Slot 2 and 3 but this fix is designed to fix all of 4 slots for Failed To Retract / Pull Out Filament Error. Why choose this fix instead of other similarly designed fix? I do think that in theory, this new fix will work great and likely even superseding in performance when
