Hi Nick,
The spec of the laser cutter can be checked out here: Laser Cutter - Trotec Speedy 300
You could cut a piece as big as 726 x 432 mm as that is the bed size.
We just happen to purchase sheets from SLEC which are 1220 x 600 and cut into 3 pieces of approx 400 x 600 which is generally OK for most people but of course if you need to use something bigger then you could purchase yourself but for us to trim to that size we’d have a lot of waste?
What size do you want to cut? We could potentially add some materials into a future order for yourself and you could buy it and cut to the sizes you want if the 400 x 600 does not work for you?
Let me know, always open to discussion on this…
Thanks, Steve
