Two mills ? was created by piasdom
is it possible to run two mills with emc? they would be side by side(no area network)
but i can't run two axis, so i'm guessing not ? thinking for getting another mill
but don't want all 'dem puters pile up. got two now(1 XP for engraver)

Do you want to run both mills at the same time? I think that would be difficult. How would the G-code know which "X" you wanted to move?
For non-simultaneous running I can think of a few ways to do it, probably the easiest would be the way I run my combined mill/lathe, where I use two different configs, each of which use the same hardware, but call the axes different things.
You could easily have a 6-stepper Mesa config, for example, with X mapped to stepgen.0 on one machine, and stepgen.3 on another.

was thinking i could send one file to that machine and another to the other.
but the axis XYZ i didn't think of. but i could use UVW for the other mill.
or even ABC right ? but i would only be able to see one plot in axis. how about
combining two drawings and use XYZ and UVW. then i could see both plots![:) :)](/media/kunena/emoticons/smile.png)

It would still be difficult, as the XYZUVW moves are all seen as paths of the same trajectory, so each g-code line finishes at the same time.
So,
G1 X1
G1 U10
Would be alternate moves on each machine, whereas
G1 X1 U10
would move both machines, but X would move at 10% of the speed of U. So you would need G-code like:
G1 X1 U1
G1 Y1 U10
Or similiar to keep both machines moving at the correct feedrate.
Just hide a mini-itx board in the back of the machine somewhere, and run it headless by ssh -X

well, couldn't one file use XYZ and the other UVW. run one before the other ?
one file use
g1 f4 x1 y2 z.2
..
...
..
...
other file(in same plot) use
g1 f4 u1 v2 w.2
then i would have the trouble connecting uvw to a sherline board.
(has A already.)
or u wouldn't act like x and v not y ......... ?
wouldn'y it just be a 6 axis mill ? may be stupid
question as i have no idea how the axis act.

G1 X1 U1
G1 Y1 U10
but if i did use uvw till the end it would move with xyz.
you have x and u together on the line, i meant use
all XYZ then UVW. uvw wouldn't move till they were
called. right ? as long as i don't use xyz and uvw on the same line.
go x0 y0
g1 f4 z-.2
y1
x1
y0
x0
g2 x-.25 y.25 j.25
then
g0 u0 x0
g1 f4 w-.2
v1
v1
v0
w0
g2 u-.25 v.25 j25

I would think trying to run two mills at the same time with the same program a nightmare... The simple solution is to have each one have a separate configuration.
The other simple thing is a D510MO... my case is 8" x 13" by 5" tall so pretty small footprint and $80 or so for the motherboard...
