I know this is my design but I feel the need to reiterate that there are a lot of thing that could go wrong with a bigger design. Things don't always scale like you would hope them too. If you have a good engineering background and/or a medium/big budget to absorb mistakes then this is a project for you.
Leveling in general on any big build is always a problem.
For this design, twisting of the arms is a consideration so scale the arm dimensions with everything else.
The screw size and the backlash of the nuts are another big concern. I posted a formula somewhere on this thread but know that is what I consider the edge of acceptability.
Firmware doesn't currently exist for this. (I am sure we can modify marlin and get the autoleveling to work but this hasn't been done yet and will have to be done by one of us. I am happy with the software preprocessor so I will probably wait for others to tackle it.)
This is more but I hope I have given anyone wanting to build a mega LISA a moment of pause. $1000 may be just enough for a 2X version (I would budget more) but I am uncertain about for a 3X version. Expect mistakes and expect budget overruns. Don't get me wrong. I want mega LISAs to exist. I just don't want anyone to unintentionally jump into the deep end. Happy building!
