Sorry this took so long… my video software is acting up, and keeps crashing.
I have gone through all the trouble-shooting steps that you mentioned
in the below email, and that were also found here:
The linked video contains nearly all the steps. I didn’t video the
assessment of wobble on the platforms, but I did assess them, and they
felt secure. I also didn’t video myself tightening all the screws –
but believe me, I did, and I have done so numerous times now trying to
fix this problem. They are secure.
The main findings from this endeavor revolve around the linear module
I’m calling #2. It has a “domed” platform, it is subtle, probably
high in the middle by about 1 - 1.5mm. You have to look closely on
the video to see it. I didn’t have another flashlight (I was using my
phone), but you can see it if you are paying attention.
Linear module #2 is also notably louder than #1 when operating at
F415. The more assembled the snapmaker gets, the louder it gets… I
think this is because of the bad linear module #2, and it its fighting
with #1. The other thing to note here is that the noise gets worse, as
Y moves toward home (bed moves away from me).
Based on this exercise, I’m thinking I have at least one bad linear
module (you can see the ‘x’ marked on it on the video).
Please watch (and more importantly, listen) to the linked video. I
think it makes it pretty clear. As loud as this gets, and as much
vibration as it has it gets, it is at least 2-3x louder when actually
printing. My SM2 is UNUSABLE right now. It is just so insanely loud,
I cannot run it. Please help.
