I fit a small square file to my jigsaw for cutting square apertures after a pilot hole has been drilled.

Also it helps if you "back off" your drill bits for plexiglass. Backing off means grinding back the two sharp cutting edges of the drill bit a little, grind the edges off so the cutting face is 90 degrees to the material. This stops the drill bit digging in and breaking through the other side untidily. The same process is good for drilling soft metals such as brass and cast iron too. Don't push hard on the drill, go slowly and let the drill bit cut the material away slowly. Lube the plexi with a spray lube such as CRC or WDF to keep the plastic cool when machining, it also stops your jigsaw blades and files clogging up.

Correct me if I am wrong, but a laser engraver can only engrave things - it cannot cut this out like a CNC machine can.

thanks auto cad but know i am mixed upi thoght that a cnc router and a lazer engraver,cutter dont they do the same job??in my case it is to make panels from plexiglass so i can cut all holes neded with acurese 100% and than once i paint them to be abel to engrave on them for backlighting so dose the jetstrem do the jobor do i need a router cnc????

This info says that it will both engrave and cut acrylic - Just a question of what power setting you use.

The data suggests that you might need to buy the optional cutting table as well

The info does not state what the maximum depth of cut is - But I assume that you just make multiple passes until you get through ? - Any experts here ?

I would be interested to know how much it costs - I'm guessing about 1500 Euro

Cheers,

A laser cutting machine will cut things, I was only cautioning you on something called an "engraver". A laser machine will be much more accurate than a CNC router, but I expect the cost to be much higher.
