KaleCNC laser on arduino

[shadowofsoul]

Hi everyone

i'm a noob on this matters, but i'm looking to build a CNC laser cutter. i was searching for lasers and i found this one:

http://www.kalecnc.com/index.php/front/productDetails/19/15

seems to have a pretty good construction, and i suppose it would be enough to cut 2mm plastic/wood (if anyone has any better recomendation, i'm open to suggestion)

what i don't know, as i never used lasers, is how is this connected and controled with arduino. I suppose by using TTL but can be this wired directly to a PWN pin? can anyone point me to info about this so i could learn how to use it?

also, has to do with this thread, but can recommend me any safety glasses for this laser? again, i'm seeing tons of different models and i don't know which i should choose.

sorry for so noob questions, and thanks for any hint you can give me

Regards.

Yes, it'll work fine off any (5V) Arduino I/O pin. Be careful as some models of Arduino are strictly 3.3V.

It may cut 2mm plastic/wood, but it'll be very slow going.

As far as safety glasses these are what I recommend:

Eagle Pair® 190-540nm Standard Laser Safety Goggles

Hi Shadow -
Watch the current. On an Arduino Nano, regular I/O pins can only source 40mA. The 5V pin can output up to 500mA, with some of that reserved for operating the Arduino itself.
