I will have to check and see what sizes my local stores have. 1200×800 sounds like a manageable size though. I am from Sweden and I have not yet bought my tubing. I have seen 25mm aluminum tube with 1,5mm wall at the store but then I wasn’t building this 🙂 going shopping for tube and bolts/nuts sometime this week. I have most of the electronics on the way from different parts of the world but I need to decide on a router soon. I will be using this machine to also cut/engrave acrylic and wood.
