No, it would not get you to ns levels. The reason is that the
computer is not always in a state where it can be interrupted. The
hardware trigger (line going low) would happen but it has to wait
until the computer looks at the trigger signal. It only does this
between machine instructions
Hello all. I am wondering if the universal stepper controller from Pico
Systems requires an external 5V power supply or not. And, if so, what is
the current requirement and to what terminals should I connect it?

Typically 0.1 bypass caps REALLY to have to be physically close to the
load they are bypassing. Within a few millimeters. Cut the leads
short and bridge the power pins with the cap.
Placing a larger cap farther away can't cause any harm but it is not
going to do the same job.

I seem to be having some success with this. I have a simulation config set up
with max velocities set to 100x, and max accelerations set to 1x,
feed-overide set to 100x. Using my scaled timer set to 100x the estimated run
time seems to be pretty consistently about 25% too long for a 20

I guess I am not following how a hardware interrupt gets mapped to the

Greetings everybody;
A bit too cold this morning to go out to the shop and saw out the thicker
spacers I am going to need to permanently mount the Z motor and screw
anchor.
So, not wanting to waste the day waiting for it to warm, I went back to
work on the encoder thing this morning.

A quick stupid question, if i'm scaling time 100x, velocities should increase
100x, but what about acceleration, should that be increased 1x or 100x?

All I could find there was concertina style, some folded to interlock

The ones I got I found on ebay, and I got those more or less installed

Setup a Mesa card with a periodic timer that triggers a capture of the

@Sebastian Kuzminsky Thanks for those docs.
@Charles Steinkuehler
How would you link an interrupt to linuxcnc?

I forgot to mention the system clock. As is in the software libraries it is
a variable although in almost all applications I have written clock
frequency is assumed to be constant. Then I started to program I usually
defined clock frequency to be constant since it is known at compile time. I

It might you used to register call back style functions but it is a lot
simpler to tell which functions will be called if function calls are added
in interrupt handler. The software I write usually is very simple and one
of the reasons is I use the static approach, it have limitations but are

You can choose to any of several libraries. I have an ARM M3 right
now using the Arduino IDE. Can't get much simpler than that.
Another one, an M4 here is being programmed using "mbed" library
because I need to do something more complex that needs an RTOS but
mbed is also very simple,
