Number of Screws for the Laser Engraving Platform

The laser engraving platform assembly instructions call for the installation of 8x M4 x 10 Hex socket head screws. However, I noticed the bed rattles a little when I don’t have the addition of 4 corner screws screwed in. Were the instructions just a little out of date? The metal platform has holes for up to 12 screws so I utilized extra screws to bolt the whole platform down to the linear motors.

Thoughts? Also not sure I’m a big fan of the black T silicone plugs but I’ll keep using them.

My first laster print test is in progress and now I get why people are ordering the enclosure. :smile:


You didn’t say which model you have.
On my A350 I use 12 screws to hold down the 4 laser bed plates.

The plugs are awful. Someone on FB redesigned them to print out of TPU, but I lost the thread and never tried printing them. I just use blue tape for almost everything on laser.

Definitely puts off some smell and smoke even with just wood.

Sorry about that, it’s for an A350. I’ll stick with the 12 screws. Thx
