In the DONE section of the following wiki EMC page:

hi all,

I take it that EMCMOT_MAX_DIO is compiled into EMC (emcmotcfg.h). So if
I need more than four m64pX's I would need to compile my own EMC? I
suppose being able to compile my own EMC would be a good thing, but I'm
trying to put it off for later. Thank you.

You'd connect the commanded position to change-detect, and the output
would be the "full current enable" that you are requesting. You could
stretch its output with the "oneshot" component so that the amplifier
current limit doesn't go down instantly when there is a programmed pause
or the like.

The stepper driver itself is not shut down. Only the reference voltage
(which stears the output current) is lowered to approx. 10% of the
original reference voltage.

My only question would be - how are the stepper drives shut off? Is the
power removed from them? When they turn back on - will they be at the right
phase sequence as when they where shut off? You could be as much as 4 full
steps off if I am thinking correctly.

Hi.
Due to the way our machine drives the axes, we would like to turn off
the amplpifiers when no axis moves (even when the spindle is on), since
the steppers get really hot if they don't move but are driven at full
current.
However, axis.*.amp-enable-out goes true as soon as the machine is

emc2 offers "feedhold" and "adaptive-feed" pins in HAL (the latter is
activated by M52, not on by default)
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.

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 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.

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-s
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 F[

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:

With this lines you could perform simple math like *+-/, sqr, If,
