Please pardon the crude graphic. The red line is the laser. Knowing that the laser cuts straight down, does anyone know of a way to make a cut at a 45 degree angle? I have a Thunder Nova 63. The head is fixed like most lasers. Wondering if there is something I can do with the wood, acrylic so far as placement goes. Any thoughts would be appreciated.
Hi.
Easily and affordably with a CO2 laser, using LB, unfortunately not a chance.
A diode or gantry mounted fiber would be easier, but no means an easy task either.
However…
The age old patternmakers trick is to tilt the band saw- or router table in order to acchieve the required angle of draught onto the sides of the pattern, and that can be -and sometimes is- used on manual and CNC mills/routers with the aid of a tiltable rotary table.
The manual milling/routing is relatively easy, but with CNC there’s a catch though, the software have to support at least 4 axes of freedom.
And since most support 2 1/2 axes, we are SOL so to speak.
IMO the only feasible way to do cut at an angle would be a robotic arm with a fiber laser.
Guaranteed not to be cheap

Two issues:
[1] You would have to make a tilt change for every path direction change.
[2] Your material thickness may increase 1.414x and be way beyond what the laser is capable of cutting when tilted.
Use the laser to mark the material, then cut it out on a band saw tilted 45deg.

I needed an angled cut once and made an angled material holder for the task. It worked fine but is limited to straight lines and only a certain material thickness. But yes, it can be done but it is cumbersome.
Thank you. I will give this a shot.
It sounds like you are getting into cnc machine territory here.
Using a 90 degree V-bit to make 45 degree cuts on a cnc machine is the way to go here.
