My Sainsmart 4040 Pro CNC Developed a Lead Screw Fault @Tonys.Top.Tips.Workshop

Uploaded October 2024 | Updated September 2026, 2 weeks ago

My Sainsmart 4040 Pro CNC Developed a Lead Screw Fault caused by a clogged anti-backlash nut. I show how I have tried to reduce the amount of debris from cutting operations landing on the guide rails and lead screws. With the aid of 3d printed guards.
