Hi Len,
Sorry if I came on a bit strong there but I do a lot of repairs on CNC
machines. I have seen what happens when things go wrong and it isn't
pretty. If you are selling these machines I would still be carefule with
the EStops just in case.
Apart from that rant, this is an interesting
By coincidence I was just working on adding a bit to the manual on components
and threads
and how to make it all work together.

What exactly is the purpose of the Pluto-P interface? Does it just give more
I/O than the parallel port, or is it somehow faster (I am guessing not)?
Thanks,

The Pluto generates step pulses in hardware, which means that it can
deliver higher step rates than the simple software

Hi everybody
First of all, I am using EMC2 on an old system it is a
Celeron 850 MHz coppermine CPU with 192 MB RAM
the machine is a wood router with 3 axis system from xylotex
the version of EMC2 is 2.2.7 from the 6.06 ubuntu version
I had installed the 8.04 hardy version but this older

It is probably the cheapest hardware step generation option, but that
shows. The quality of the board is marginal, connections are to tiny
headers, etc.
The price difference between knjn.com's pluto-p ($60) and mesanet.com's
So it IS a hardware step pulse generator. Great!
So I assume it receives its commands in 8-bit parallel?? Which would be
faster than serial.
But could it be made to run serial?
