ohn K for editing that manual at the LinuxCNC fest in Houston last year.

My printer will do 13" x 19" and the machine is a simple gantry router with
a 4th axis rotary, ought to be big enough, even for these tired old eyes.
Sounds a perfect solution, at least to better understand what's there now,
before I go re-routing spindle control... LOL

Hi Andy , thank you for the reply.
It's not the matter of change the discussion object .
But when somebody as expert as you are is writing an important concept I
would like to understand it properly.
Sorry ...

There isn't any HAL logic elaboration as you seem to be describing it.
All the HAL logic is handled by individual components. Those
components read their inputs and update their outputs one by one

It reads that way, but that isn't how it runs. Every component reads
its inputs and updates its outputs exactly in the order they are
"addf"-ed to a thread, and they do that every time the thread runs.

Does your VFD have an at speed signal to use? Most of the VFDs I have used
have a digital output that indicate when they've finished their ramp up the
speed. I have had pretty good luck connecting that to the
motion.spindle-at-speed input. It isn't perfect, but works good enough for me.

It possibly helps to realise that it isn't a programming language, even if it
looks like one.
A HAL file is
LOL yeah, John, I had a click when I got the MPG working, without
overriding the spindle speed meter. LOL again. The other noises I thought
to be clicks ended up just being my bad knees... I appreciate the words of
encouragement. This community never fails to amaze me, I love being a small
part.
O
Scott - Hal was a bit of a problem to learn for me, too. But then one day
it "clicked" and now it's not really a problem. Syntax still is a bit of a
mystery at times, so I'm not near the Hal expert that many on the list is.
Keep at it, and you'll have more and more fist pumping "Yeah!" moments. ;-
It's only been 2 weeks with linuxcnc for me, and I'm using G4. I wish I had
a shallower learning curve. Speed based delay is exactly the solution I
need Hal still eludes me...

Yes, you can use timedelay:

net spindle-on motion.spindle-on => timedelay
