Why is my printer making a grinding sound?

Alright, Carolina here, your tech-savvy guide to the universe of 3D printing. Are you ready to embark on a journey of wonder, fascination, and excitement? Well, buckle up, because here we go!


Heard that Crackle or Gritty Noise? Dive into the enigmatic world of resin 3D printing with the Anycubic Photon Mono or the Elegoo Saturn, and you might be greeted with those pops and grinds. Trust me; these little sounds will make your ears twitch in no time. But why the symphony of sound? And can it be tuned down? Let’s zoom in and unmask these mysteries.

To put a stop to the cacophony from your resin printer – be it a knock, grind, or screech, ensure all those screws, from the thumb-sized ones to the tiny ones, are held in a tight embrace. No wiggle room here, folks! Clean up after your printing session and don’t let that cured resin party in the vat. Shower some love on that Z axis – a good lubrication session is all it asks for. Remember, a harmonious build plate is a quiet one.

Are you ready for a deep dive? Follow me as we explore more about the “Why’s” and “How to’s” of these pesky noises.

Why is my Elegoo Mars or Anycubic Photon Singing Me a Crackly Lullaby?
Yes, your printer might be serenading you with some popping sounds. It’s just the sound of the FEP film and the build plate playing a game of tag, with the cured resin layer stuck in between. This noise is as expected as your morning coffee aroma. However, if it gets too loud, it might be due to the cured layer having a tad too much to drink. Need a tip? Angle your resin model to minimize this noise.

Why the Knock & Grind, Elegoo Mars or Anycubic Photon?
If you’re hearing these knocks and grinds, your printer is trying to communicate. Maybe there’s an unwelcome guest in the resin vat, or perhaps the build plate is a tad too ambitious and tries to exceed its limits. Normally, your printer should be humming a soft tune, not hosting a rock concert.

Let’s Get to the Bottom of It!

1. The Symphony of Screws: One of the leading members of this orchestra. Ensure every screw – from the vat to the stepper motor – is tight and in harmony.

2. The Resin Tango: Cured resin left at the party? Ensure no missteps in the bottom of the vat.

3. Z Axis Groove: This axis loves a smooth dance. Lubricate it with some PTFE spray for a flawless performance.

4. The Build Platform Ballet: Ensure it’s level and poised for a stellar show.

5. Setting the Stage: Ensure your build plate knows its boundaries and respects the screen.

6. Z Axis Rod Rhythm: Listen to its beat; if it’s grinding, it’s time to tighten up its performance.

7. Harmony of the LeScrew & Linear Rail: Their duet should be harmonious, not screechy. Misalignment might be the culprit.

8. The Limit Switch Solo: Ensure it’s in tune and not faulty. If it’s off-key, it could disrupt the entire performance.

So, there you have it, the ins and outs of what’s making your printer sound like it’s about to drop a mixtape. Here’s hoping your next print session is a harmonious one!
