Hi, this is new to me, have had a look on wiki, i get the basics. but not enough to understand.

I want to cut from Foam to stone, using a few different spindles if required. So

1. Does using sensor less vector mode give better toque at lower revs, on a standard setup.
2. Is this enough of a difference to be usfull ?

I clearly dont know what i need to know with this, so fire away with any info

Bart - i am designing/building a similar machine, hop you dont mind me jumping in and asking a question on your post
