You have a laser operating in the visible light spectrum and want a see through door to get a better view of it in action?
Might be easier to just drip acid into your eyes or to use a soldering iron to cauterise them…
The green is basically the opposite of the blue laser light - next to nothing makes it through and being acrylic also blocks the remaining invisible light that is emitted.
You NEED the right protection for a laser if you value your eye sight, especially if playing with the 40W version…
Go ahead and check what’s available in terms of protective goggles - that is the minimum required for a front panel…
And considering that it makes no difference - protective goggles or a protecting door.
I do agree though that a a removable panel or quick release door should be included if you buy this thing with a laser…
But that also makes it invalid for EU use and probably US use as well - there is minimum requirements for the laser safety and I guess that is the main consideration for Bambu - they can control what you get but not what you make out of it…
Front, much less visibility. Could easily be engineered to match the side views. They have used two layers of green Perspex, to get the door strength required no doubt. A glass door with a protective inner layer the same thickness as the sides would give the same visibility as the side and a stronger / higher quality door feel.
I have wondered why the side windows are nice and clear while the front door is foggy. I personally don’t plan on using the laser much, if at all, so I swapped my door for the glass one. If it was clear like the side windows I probably would have left it alone. Maybe it’s foggy by design? More protection through the window we will be looking through 99% of the time.
If I ever need to do laser stuff I’ll swap the green door back on. Takes 30 seconds. The laser won’t operate if the green door isn’t on so there’s really no risk of “forgetting” to put the proper one back on.
the front door is a moving part and it’s large, so it’s made by acrylic to make it cheap and also less vulnerable to breaking. Large, laser filtering hardened glass would be much more expensive
You’re not wrong, it’s terrible for using as a 3D printer - like looking at my prints through green milk. And yes, the sides are fine. I’m swapping doors but would love a better option.
I totally get the frustration with the dark front door. I’d love to see a single-tinted glass option from R&D too, keeping the view clear like the side panels.
I missed this old thread when it first went around but
Hopefully they didn’t do any swaps. Just getting green plexi is no guarantee it is safe with the laser. It takes instrumentation these guys won’t have to know if some piece of glass or plexi is safe to use with a particular laser wavelength.
The plexi can look the same yet still let damaging radiation through. Interlocks have nothing at all to do with whether side glass or a door are unsafe for blocking laser radiation unless they are somehow keyed for the OEM door and detect unauthorized swaps.
I hope nobody followed these unwise folks in their misadventures. Some of the most unsafe posts I’ve seen here.
Wonder if they have had any eye exams since they did this stuff and what their retinas look like.
Just a clarification:
Switching the door to normal version only allows you to do 3d printing. You won’t be able to do laser because the doors are different and the normal door doesn’t have the magnet to trigger a hall effect sensor. The sensor is used to make sure that you’ve shut the green door for laser. The firmware enforces this security check.
It’s good Bambu went the extra mile to help keep the industrious from defeating the interlocks. Only thing is swapping out parts intended to protect users erodes protections.
In just about every accident there is a chain of events that leads to an accident. Safety steps are skipped, protections are removed, procedures get modified. And each one of those and others helps the holes line up.
The consequences of this can be severe. Or not. It all depends. Some may treat these mods with respect and others may not. You guys do what you want. People should know that each protection that gets defeated moves them closer to an accident, though.
