Hi Kitwan, I am struggling with the software to be honest and just cannot decide which option i should choose. I laid out half a sheet of 22mm MR Medite MDF last night as i want this to be under a workstation. Although i have a big workshop, space is still a premium and i think the largest machine i can get away with is 800 x 800. I dont know what that means in terms of actual cutting area. But an 800x800 machine takes up more space than that once you factor in the motors etc. I have allowed 100mm all the way around the machine, is that reasonable or not?
