crafty geek, if I may make a suggestion here: try aliexpress, they're really cheap, I recently purchased a customized 1.3 x 1.2 meters etched...
you might want to try autocad, it's intuitive and if you understand geometry, you're game. precision wise, goes up to 8 decimals, 16 internally....
found this formula a while back: (specific heat of aluminum x volume of plate x aluminum density x change of temperature you're looking for)/...
if you only knew... had to climb a box to get it all in the frame. a nice cube, 1500 mm (59"). printing area: 1270 x 1100 x 1145 mm (50 x 43 x 45...
