@A2: I think you have some facts wrong.
I am able to print accurate squares and round objects with much greater accuracy than 1mm. I have used it to prints parts for my GUS retrofit so I would say it is trust worthy once you have it calibrated. I would put it against almost any other printer. (Note: I have some slight screw wobble artifacts that can be addressed.)
LISA geometry is dependent on the rotating nut. This feature is an asset which aids in its simplicity. Any work to keep the nut from rotating will require many additional components that will probably cause a decrease in. accuracy. (For instance to keep the nut from rotating you would need some rails, linear bearings, and another joint with some 608 bearings so the shoulder can swivel.)
LISA can theoretically print all of her parts by design. I would probably split the arms in two because they are a bit on the long side. I will hold off on the self-replication until I build my second machine which will address some of the screw wobble issues.
There is really no reason LISA can't be squeezed in firmware. It just has to be done. It is marginally more complex than a regular column delta. However, accuracy will be the same whether you use a preprocessor or you use firmware.
