Vyper Extruder Grub Screws Issue

A common issue that many people have with the Vyper (and its common to many BMG clones) is the grub screws coming loose. Its a very simple and quick fix or preventive routine..
If you are hit with this problem, you may find the vyper making clicking noises or grating noises when retracting and feeding filament, holes and gaps in layers, and eventually total loss of filament extrusion.
Check it out and prevent it from the get go is my advice ;)

Awesome! I really like these type of maintenance tips you make. One doesn't see them that much for this printer. Anycubic should use your vids on their site, and that would go a long way for both of you. Explanation is spot on and thank you.
Cheers

Hi, Just one may be small question . How can we know the normal calibration on the filament of the screw. Is there only by checking the filament if we remove the tube and extrude 100mm for example. And if the answer is yes. What could be the apparence of the filament to know if it is not to much or not to low. Thanks in advance for any info or picture about the correct aspect of the filament when it is weell done . All you video on maintenance on the Vyper are nice thanks

Thank you so much for your video. I think you have just saved me some money, and now I can fix the issue without purchasing a new motor. Happy New Year! :)

Thanks Louise 😊 keep them coming mine developed a hot end fan noise when it starts and quiets soon after what fans should I get to replace them? Thanks

[@Just3DPrinting]

depends which fan..
If it starts when temp gets up to about 60c then its the 4010 axial fan for the hotend, if it starts on layer 2 or 3, the 4010 radial blowers..
Both 24v of course

[@lyledonauer3934]

Thanks Louise it is the blower fan
