As far as I know the only 'self squaring' fences on mobile table saws are the Bosch GTS 10 XC and Dewalt DW745 (and some other DeWalt models with the same rack and pinion system)...MichaelW2014 said:"but when I do that, mine isn't straight." Eh, yuck. Now I am totally put off on the fence.
If we all could agree on some of the fundamental problems with the fence(s) then we could sign a petition or some kind of letter that we could jointly send to Festool to let them know we want a better fence for the CS machines. They might actually take notice.
But as said here before as long as the fence is parallel to the blade and you only use it as a guide and not bent it out of place it should work just fine...
