Re: [Emc-users] Mesa 8i20 as a spindle drive
I'll be controlling it via hostmot2. I just wasn't sure if the driver could be commanded without an encoder.

You should be able to generate the right effect with siggen.sawtooth. http://linuxcnc.org/docs/2.8/html/man/man9/siggen.9.html -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

[Emc-users] Mesa 8i20 as a spindle drive
Does anyone know if it would be possible to use a Mesa 8i20 for a 3 phase spindle motor? No encoder just for a router. Thanks, Curt ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Hi all
Does anyone know of a document or a description somewhere that
explains the contents, structure and possibilities of the Mesa PIN file?

Theres a bit of a description in the main constants file:
IDROMConst.vhd
Thanks Peter I have much clearer picture now. Just one description that
is not clear is the "PinDescType". What I see in the array is not
explained in the definition.
/type PinDescType is array(0 to MaxPins -1) of std_logic_vector(31
downto 0);/
and what is in the array is:
/IOPortTag & x"00" & StepGenTag & StepGenDirPin, -- I/O 00/
The second field in particular is not clear to me.
