I’m new to Snapmaker and was running through the beginner guide. I was engraving the ruler and protractor on the 150x150 supplied plywood. The settings were a little hot, there were some burnmarks around the cuts but that’s not a big issue. what i had a problem initially with was the module crashing into the screws of the hold down clamps. I ended up just setting the material on the bed with no clamps.
If you have the enclosure and accept the dangers, I modeled up a replacement plate that removes the shield just for this very reason.

Thanks, I already broke the glass on it. It rammed right into one of the screw heads. I was looking at modeling adjustable corner clamps with an extended arm
Still have the bonus of you get a bit more Z movement. If the lens is already broken, might as well print the replacement and don’t have to worry about the hold downs.
Found a solution for smaller material. Placed various width strips of wood between the hold down and material.
Also, I contacted snapmaker and they are sending anew baseplate to me. Very good customer support.

The Snapmaker Wiki mentions you shouldn’t use the provided screws/fixtures for the 40W laser.
Rather than modify the Laser Head itself you can just attach a honeycomb bed to the existing bed with something like this:
The honeycomb beds use rubber fixtures that are nearly flush with the bed and so you won’t have issues running into the laser head. Also I like the fact that it raises the bed a little bit giving some more room for air flow.
At some point I may install a vent that sucks out air from the original bed (under the honeycomb bed) and reduces the smoke in the enclosure.
The main downside is the bed+honeycomb bed is quite a bit heavier, but I found it’s not too bad. You also lose about an inch in the Z-direction but were you really going to engrave something that that is 370 mm high up? I don’t think so.
Makes sense but why not provide that. I printed some low profile hold downs that work great. Made this yesterday.

Nice. Yeah agreed that SM should probably ship the 40W with appropriate fixture hardware.
I also found that the bed is capable of lasering greater than 400mm. I printed the wine box above on A3 (297x420) and it framed the entire piece in Lightburn.
