Hi Everyone. I'm new to the CNC game. I've been using CO2 lasers for a while but the CNC bug finally bit me. I ordered a Lead 1515 and am waiting for it to arrive. My question is on the table. I've seen some table builds that seem like overkill (cross braces every 12" and solid oak). I also saw the table kit that's in the store made of 40/40 beam. The question is, does a sturdier table (multiple cross-braces) make for a better result? I'm thinking that if the machine is fixed to the table and the table has little tendency to shift out of square (under force) that the accuracy will be improved. Does this make sense or are the forces applied by the machine (I know it depends a little on what you're doing) not have that large of an impact? Would a table made from 40/40 be fine or would one want something sturdier for a machine this size?
A good supporting structure underneath the machine certainly helps. Bracing to prevent sagging, absorbing machine vibrations, improving your workflow by also helping you store and install accesories all adds to the experience. Accuracy in terms of Z-depth can benefit a lot from a surface that helps keep the machine frame rigid, and mounting the machine solidly to an immovable worktop will help things stay straight for longer (less maintenance) Small aside, if you are going for a DIY table, see The Ultimate Torsion Box Table Thread for a comprehensive earlier discussion
Like Saul, I have 1515 en route. I have quite a bit of extruded aluminum so I plan to build my table from that. My plan is to build approximately 3-4X8’, place it at the front of the garage with long side against the wall and be able to put the hood of our car under the table when not in use. I will be using 1.5 X 1.5 X 24” angle supports for the legs. I am oversizing the table because I plan on cutting 4X8 sheet goods and slide through cutting each half in turn. I am hoping to get some guidance on what material to user where, primarily choosing what to use for the front and back long section, making the best use of what material I have on hand and what to cut for the spreaders. Any guidance is appreciated. Below is my list of available material: QTY. 2 3X3X96” 4 1.5X4.5X92 2 1.5X3X128 5 1.5X3X38 (Thinking of using these for legs)
