Re: [Emc-developers] time delay hal component for lube pump

[Hans Unzner]

Good idea to make the lubrication based on the travelled distance.
Here you find a solution in Python you could adapt. It saves the
accumulated distance in a file and shows some statistics:

How close is http://linuxcnc.org/docs/html/man/man9/oneshot.9.html to what you 
need? Should we possibly extend it for whatever is missing? And/or should the 
description of oneshot improve?

That is what I also thought. Conceptually, just need to develop my respective 
skills a bit more.

Re: [Emc-developers] time delay hal component for lube pump

[Stefan Freisei Muehlbacher]

Some time ago, I have written a small component which pulses at 
machine-start if last lubrication was a configurable time away. Next 
pulse is done if the way the machine has made in sum of moving of the 
three axis hits a configurable limit (or even if the last lubrication is 
too long ago again).


I guess two little components written in my poor c (one for saving the 
way-values on exit, the other for calculating/shooting next lubrication 
by time)   the rest (way-calculation) is done in simple HAL.


If interested i can search for it.

I don't believe that the oicontrol.0.lube-on signal pulses, which I
think was required.

I can think of at least three ways to generate a suitable signal in HAL.

low duty-cycle pwmgen
stepgen
siggen clock pulse driving a oneshot.
timedelay with the output connected to the input. (might not "boot")

Subject: [Emc-developers] time delay hal component for lube pump

Hello, all,
I need a hal component for a lube pump.  What I am looking
for is more like a one-shot than the existing timedelay
component.
timedelay seems to be able to delay the start or the end of
a signal, but output will follow the input after the delays
occur.  I wanted a component that would trigger for a set
time after a trigger (or LinuxCNC starting) and then, I
could or it with the spindle enables.  This would ensure the
lube pump starts immediately when LCNC starts, and then run
whenever the spindle is on.  Anybody know a better way to do
this?
Thanks,
Jon

How about a really slow, low duty-cycle pwmgen



I have no idea how long the silicon tube in a $10 (ebay when I bought a 
4 pack expecting short life, but 3 years later I'm still on the first 
one) peristaltic pump would last pumping vactra 68. But I have such a 
beast on my 6040 driving the mist atomizer. Its a 12 volt pump, and I 
rigged up a two timer circuit that pulses the 12 volts to it about 5% of 
the time, quite a few times a second. I've rigged up pyvcp sliders to 
control it, and I had an 8 oz coke bottle  with diluted koolmist in it, 
last as long as 8 hours while doing an awfully clean job of carving 1/2" 
alu into er20 wrenches.


If interested, I'll put some pix and config tarballs up on my web page. 
You can cherry pick whats useful.  With my setup, finding a mist spray 
head you can point at the tool that actually works is the biggest 
problem. Much less of a problem if the oil plumbing is already present.

There is an existing oneshot component:

But, way overkill for just one function.
Maybe I should use timedelay as a template and write my own 
one-shot component.
