He is probably looking for something a bit more industry standard.
Like G65 simple macro call and G66 modal macro call with G67 cancel, with
more normal looking argument assignment.
Like this one using argument assignment type I.
G65 P1001 Z-0.750 R0.100 D#101 A#100 F#9
Then there is assignment

Hi EMC2 pros
I was using 12 years IBH CNC: http://www.ibh-cnc.com
They had so called Parameter sentences.
A parameter sentence was always one Line, and startet with a star,
for example:
*N10 P43=4000
With this lines you could perform simple math like *+-/, sqr, If,
goto etc, you had about
Ask user to define minimum and maximum X, Y and Z positions by moving
the tooltip to the relevant positions manually or by entering the values
numerically. Then use a procedural (possibly recursive) approach to scan
the work pieces surface with a touch probe.
Not the most advanced waz to do
In emc2, these are known as parameters. The # character is used to
set them or use their values.
A parameter can be set with gcode like
#43=4000
and used like this:
X10 Y10 F#43
Math is supported:
#43=[sin[45] * 300]
and can be used anywhere a number would be used:
X10 Y10
I'm
sure there is a way to solve that problem, but nothing springs to mind
right now.
how about a long limit switch (between 2 encoder indexes), just use a latch
to toggle the state.
to summarize: actual switch AND encoder index - toggle signal for the
latch.
latch output - emc home-sw
Cool!

'I think' that jepler has already increased that - I have 2540 line
encoders/w index which are 10160 count that I have not tested yet but I
think will work now.. I actually think he went about the encoder counting
different so it isn't an issue.
I am sure jepler will chime in here. :)

The rating for the SoftDMC configuration is ~3 MHz if the filter is
enabled, and faster if the filter is disabled.
SoftDMC is not the config used with EMC2, but I think the encoder
counter is the same, so I'd think it could count at 3 MHz or better,
depending on noise filtering.

Typically, how long can the cable be between the UniversalPWM controller
and servo amps? The amps have differential PWM and direction inputs. I
assume they are RS-422 compatible? (Just keep below 10 mA through 1
kOhms?)

The change in emc2.2 will be to allow any number of counts per index, so
long as the maximum number of counts per servo cycle is within the
permitted range. I made this change for sam and his 10160-count
encoder, but I am not sure he's actually tested it with the updated
version.

hi all,
just wondering if anyone has used a Q2HB44MA stepper drive
( http://www.bsjd.com/_en/products_show.asp?Productid=424 ) as I have
just acquired some for my new mill.
which is best a step/dir signal or CW/CCW signaling for steppers?
