Adding a Laser to a cnc machine
Wasnt sure where to post this so her we are
I have a cnc machine similar to this
and I want to add a laser that can do engraving and cut up to 5mm perspex and plywood.
Would something like this be suitable

no chance with that laser mate.
a few issues you have.
1: pretty sure that cnc does not have an input for PWM
laser
2: That diode laser will struggle to even etch onto balsa.
3: it could etch perspex if it was painted or taped up first.
4: even at 100% 1mm sec it would take a million pass's to cut 5mm perspex.
5: even if you could connect it which i doubt it would also depend on the software
that runs the cnc.If it is run by mach 3 then it does have limitations
Diode lasers are not really capable of cutting perspex due to the frequency
also they advertise its max and not what the true output is. even the 40W that
is in the link is only a 7.5w output.
i personally have 2 cnc and 2 laser cutters 1 co2 and one 30w ( 7,5w output )diode.
If you wanted to engrave /etch perspex then you can do it with that cnc by utilising a diamond drag bit
which i have done

I mainly wanted to burn/etch pictures and letters in wood
I am using Mach 3 on the cnc machine. I will do some more research
Thanks again
first thing you need to do is pop open the control unit and find out what mainboard it is using.
this will let you have an idea of whether it can even have a laser connected to it
the board will need to have spare connections to be able to utilse pwm or ttl
which is what the diodes need .

What if I just go for a stand alone machine, is there anything you would recommend for around $1000 - 1500 dollar mark for a beginner
there is for that price point a few things need to know first up
what size pieces do you want to work on
how much room do you have in the work shop
check you pm
