Here’s a little update on the clicking from my machine with a short backstory. I purchased the machine in Dec 2020. It didn’t make the clicking sound when I first bought it and my first 2 materials were standard white as well as flexible 80A. Both of the resin trays at the time were V2, not V2.1. It started clicking after I had done if I remember correctly 2 firmware updates after having the printer.
In this time period I had replaced 1 tray as I had used its life up and it was still tray V2, not V2.1. So my machine has been clicking for some time.
Only recently after having tried tough 2000 where the mixing cycle is at every layer has it become prominent enough for me to want to do something about it. That is why I filed a case with Formlabs as stated in my previous post.
Also from my previous post I stated what Formlabs’ fix was for it and it fixed for a short period of time but the click came back. Talking with Formlabs more about it they call it a “cosmetic issue” meaning it shouldn’t cause a problem with the print. And to continue printing with it.
Other than them offering the “fix” of turning down the magnet, which was only a temporary fix, they have offered no other fix for it.
If you do start having print problems and you’re thinking it is the clicking then I would file a case and see what Formlabs has to say on it. Otherwise as said previously, it is ok to keep printing with it doing the clicking, it’s just annoying and will scare the crap out of you if you’re not ready for it.
Side note, my printer is still making the clicking noise and I have since printed with both V2 tanks as well as V2.1 and the tank doesn’t matter, and it doesn’t seem to me that the resin matters either. It does it with all 3 of my main materials, tough 2000, white, and Flexible 80A.
