Re: Aluminium Gantry Router
Nice job so far Jeremy. If you want to mainly do aluminium machining though, you'll need to stiffen up the base of the gantry, as on fast moves and under load the whole gantry will skew sideways at the base. The top is really well braced, but you need some support beams at right angles to the gantry sides to stop flexing.
Another thing that's really important, and can dramatically help, is don't be afraid to add heaps of mass to the frame. The more rigid and heavy the frame and gantry are, the better it will dampen vibration and noise, and reduce tool flexing.
looking forward to seeing how this build progresses!
cheers, Ian
