Guys,
I did it
With no thanks to you guys... no, I am kidding.
The new M6x codes were the key. And, although I have tons of experience
compiling linux programs, I have never previously needed to compiled EMC
from source. I was forced to successfully rebuild emc-2.2.2 with 48 I/O for
3 parall
Analog glass scales signals can be divided with off the shelf (or cheaper off
ebay) components. I have a heidenhain encoder that by its self has resolution
of aprox (its metric) .0005 inches then I have a box that divides by 5 for
aprox .0001 inches. The box also converts to square waves signal

I think it very important to build machine, in your case router,with AC
servo motors to you can see what software does.
than you need to find out about tune up ac servo motors with amplifiers
and EMC2 sotware. when you get somthing that moves than you can move to
homing, adding next thing to it.

I think that is the way to go to be perfectly honest.

Hi Matt,
It seems every time I get ready to do something with EMC I am interrupted. All
set to go to Cabin Fever and my co-driver comes down with the flu. Oh well.
More of a drive my co-driver / retrofit assistant are talking about the EMC
fest in June.
I am considering running Ubuntu 6.06
This is a good explaination of the trajectory control.

Hallo everybody,
I would like to know if EMC manage the look-ahead to optimize the trajectory
and if there is a customizing function.
I know the acceleration parameter affect the max velocity reached in non
linear path, but I would like understand if and how the look-ahead can
improve the perfor
I am a newbie to this as machining is really a hobby. I have an old
Craftsman 6" metal lathe, mill/drill, bench drill press, etc.
I have now become interested in CNC machining and I am looking at
building my own "router type" table first and progressing to converting
my lathe, etc.
My first ques
Hi all,
Is it normal, that looking from above on the lathe a G2 makes a
counter-clockwise arc?
When assuming a normal XYZ, the Y axis on the lath is extending
downwards and this would indeed explain this.
