I see that a piece this big is JUST slightly too big to fit in the crumbtray. I know the machine cant cut the entire sheet at once, but i just wanna not have to cut the acrylic before using the laser to fit it in.
I know theres the pass through slot, but that doesnt help me with width. Any tips / solutions you guys have? I am going to be cutting like 150 items, since im a teacher.
i wouldn’t out anything thicker than 1/4 (3mm) up on the sides of the tray and only to the edge of it - any thicker or wider will most likely cause a jam or worse -
I buy a lot of acrylic in 12x24.
step one: to the garage.
I used to score and snap my acrylic - straight edge and razor… score both sides really well, and then I built a snapping jig (not quite a clamp but a 1/2" slot to hold it) under the workbench.
Now I use the table saw. Not entirely sure it’s better; but with a big stack it is faster.
Step 2: go to the Glowforge materials shelves.
I know its another step, and in some far distant future I’d like a Glowforge with a 12x24" bed.
For now, though, that’s the best workflow.
Front to back is not a problem…but if you do not want to potentially damage your machine, do not let the material extend over onto the right and left side plastic areas of the tray. (Keep it on the gridded area of the tray.)
Same with me… Used to score/snap, which works great most of the time. Then just started using my table saw. You do kind of have to think things through though… Do I want two 12"x12" pieces when I’m done? Or a 20"x12" and a 4"x12"? Or something else?
Sometimes I know; but I have been pretty happy with 12x18 for big pieces and 12x6 for little pieces for most situations… and when bigger matters, I’ve obtained a fresh sheet (and more! because I’m in the plastic shop and hey this is cool…) without too much heartache.
No seriously don’t do that. Especially with acrylic. I set a red-sail clone (called Clifford the big red laser) on fire that way when the acrylic sagged and snagged the head. A square foot of the acrylic went up (it was impressive). Required fire extinguishers…
I bought my MFT/3 after the table saw. Being able to use it as a workbench, build table, and for cutting many of the same things I’d use the table saw for, I’m not sure I would have bought the table saw if I had to make the choice again.
If you have a sliding miter saw with 12" reach and a certain sense of adventure, you can cut wider pieces by flipping them and dropping the blade down into the kerf for registration. I’ve got some of those now for playing with full depth and snapmarks.
