I was referring basically to my 1999 GMC, which I had to convert. R-134a 
leaves in around 3 years, whereas the OEM charge of R-12 worked well for 
around 7 years.  The 2007 Rav-4 OTOH, is suffering from a worn 
compressor which while it still has R-134a in it, and I've topped it off 
once, is not doing much cooling until the engine has about 3 miles of 
35mph on it. Needs a compressor according to my gauges, not enough 
compush left at idle to do any cooling at all.  High side pressure could 
be used as a substitute tachometer.  Anything close to a normal high 
side reading is 4500 rpms.

Well, the problem is that once these things start to leak, 
they will just get worse.  Generally, the evaporator has 
corrosion due to being wet all the time, and you'll just 
keep plugging new leaks. And, plugging a pinhole leak 
somewhere in the middle of a (likely) aluminum evaporator

Isn't he the guy who used to pour liquid oxygen on cheap BBQ grills? Light one 
briquette, set it atop the pile of charcoal in the grill. Pour LOX on (with a 
long handle on the container). Charcoal is instantly ready to cook over - as 
long as you don't mind crouching down because the cheap grille is now a pile of 
slag.

Look up George Goble of Purdue.  he developed several 
mixtures of gases to replace R12.  One of them is GHG X-12.
Some of his mixtures contain a lot of propane, so might not 
be great in a closed space that potentially could leak again.
I sold him a semi-hermetic compressor that he used in a test 
rig to explore the oil return properties of his mixtures.
So, they were apparently compatible with the motor winding

I do not disable a stepper driver with anything but the main power 
switch. Using it for an emergency stop will if its moving when the stop 
is activated, allow it to continue to move/coasting, at the very least 
unhoming the axis.  That is not what you want to do for an emergency 
stop, you want it to stop under controlled deceleration as fast as the 
stepper driver can stop it, under which conditions you have not lost 
your home, while at the same time stopping it as rapidly as it can be 
stopped.

The exception to that was a calculated risk in the case of my Sheldon 
lathe, as I wanted to be able to effectively shut down the power hogs, 
without having a jungle of power strips to turn on and off, while 
leaving the pi and the interface powered up 24/7 so amanda can back it 
up every night along with the rest of my machines, so I used a couple 40 
amp ssr's to switch motor and spindle power on and of with the machine 
enable, so power is killed when there is a fault. That reduces the power 
drain to about 15 watts once the dpms has powered down the 11 watt 
monitor.

But both steppers are powered from conventional transformers, bridge 
rectifiers and a good sized filter capacitor type power supply's, so the 
supplies hold up for that fraction of a second it takes to bring the 
motors to a halt. However, that still means it will be un-homed by the 
fraction of a step where it lost power, and the step condition the 
driver powers back up, a potential half a full step positioning error, 
so I should net that in the hal file so as to unhome on a fault.  Belt 
and suspenders theory. ;-)

Anyway thats my theory on un-powering a stepper with the drivers disable, 
generally, I don't do it.

What exact version of LinuxCNC are you using?

Is this the old ja14 system you mentioned in another thread?  If so, and 
if an upgrade from ja14 to the current master branch 
(v2.8.0-pre1-2975-gc0778d66cf or there abouts) doesn't fix this issue, 
please post your ini file somewhere so we can look at it.

Normally Step drive "enable" pins are actually disable pins
so the drive functions normally without these being connected

In addition typically step drives are fairly safe in that unlike servo 
drives, they will not move without step pulses

So its most common that these pins are just ignored

If they are actually enable pins (powered to enable drive),
they can be driven by a spare step/dir pin or 7I76 field output

If your enable pins are actually disable pins (and you must power them to
disable the drive), and you feel you need to disble them for things like 
emergency stop, perhaps the best solution is to drive them with a normally 
closed relay contact so the drives are disabled until the relay is energized

You probably don't need to upgrade the OS to Ubuntu 16.04 or Debian 7 or
8, but you should definitely upgrade LinuxCNC to the latest master
(2.8-pre release).  Many, many JA-related bugs have been fixed since ja14.

Re: [Emc-users] Way OT, Unexpected Result from Refrigerator

[Dave Cole]

Kirk,

Go online and get your refrigerant license.
I did that years ago and I think it was $35 or so and it makes you legit 
so you can buy parts and stuff from local HVAC houses.
The test is fall over simple...  They offer a little readme type course 
to step you through it.
The test is online and I think they give you 3 hours to complete it, and 
it is open book of course.

R12 is crazy expensive.I would not go that route.I think there 
is an oil compatibility problem going from R12 to R134.   So you will 
need to extract the oil and replace it.Or you might want to consider 
replacing the compressor with an R134 unit.  Or as has been mentioned 
find a R12 substitute.Might want to look into what the classic car 
guys are doing for R12.   I'm sure they are not buying R12.   A 
knowledge of brazing is valuable for mending lines.

Right now R22 (which is used in my heat pump) is about $30 per pound in 
bulk.R12 is much more expensive, if you can find it.

Refrigeration is a really good skill to have.I've replaced 
compressors in my house heat pump, and a few cars now.Once you get a 
handle on it, it is really not difficult.

Dave

If you have a slow leak with R-12 in it, putting R-134a in it will 
probably let you hear the leak, its a much smaller molecule and can get 
out of a leak R-12 can't. R-134a also operates best at 2-3x the high 
side pressure R-12 works best at.  Enough diff I blew the R-12 rated 
hoses on my old gauge kit, and a new R-134a rated kit was cheaper than 
just the hoses.  I expect I'll have to charge both rigs before the 
weather gets out of hand in the next month.

You probably don't need to upgrade the OS to Ubuntu 16.04 or Debian 7 or 
8, but you should definitely upgrade LinuxCNC to the latest master 
(2.8-pre release).  Many, many JA-related bugs have been fixed since ja14.

Re: [Emc-users] Way OT, Unexpected Result from Refrigerator

[Stuart Stevenson]

I put 1,1 difluoroethane (computer duster) in my MR2 in place of R-12.
Works a treat. You need less quantity than R-12 and it is available at lots
of retail stores.

The S-Z 532 datasheet shows an R-134a version later in the serial
numbers. I suppose I could study the parts lists to see what changed and
order the R-134a parts. The tools such as the manifold gauge set, vacuum
pump, reclaiming tank, and others should not be expensive. I have enough
ice containers (plastic peanut butter jars, extra chunky of course) to
last years, plus I can move the downstairs refrigerator into the S-Z
hole while I'm working on it. I'll gain a valuable skill and tool set,
that I can use on other units in my sphere of influence. It would be
nice to tackle this "Refrigerator" once and for all. The thread link
above (thank you) will help with my issues check list.

Oops, after more thought, "You wouldn't want to put R-134a in it."
doesn't necessarily mean stick with the R-12, but there may be a better 
alternative. I'll have to work on this some more.

Hi Giorgio, I don't totally understand what you're reporting, but I
think maybe you're running into a problem with different units being
used in different places.

The .ini file file has [TRAJ]MAX_VELOCITY, [AXIS_*]MAX_VELOCITY and
[JOINT_*]MAX_VELOCITY in machine units (mm in your case) per second:

http://linuxcnc.org/docs/devel/html/config/ini-config.html#_traj_section
INI Configuration - 
LinuxCNC
linuxcnc.org
A comment line is started with a ; or a # mark. When the ini reader sees either 
of these marks at the start a line, the rest of the line is ignored by the 
software.

INI Configuration - 
LinuxCNC

of these marks at the start a line, the rest of the line is ignored by the

But the Axis GUI presents Max Velocity in machine units per minute.

I just ran this test:

I started the sim/axis/axis_mm.ini config, and saw that Axis shows a max
velocity of 3200 mm/min.  This corresponds to the .ini file's
[TRAJ]MAX_LINEAR_VELOCITY of 53.34 mm/s.

I then used halcmd to poke at halui.  I first saw that
halui.max-velocity.value was 53.3 (mm/s), roughly as expected.  I
set halui.max-velocity.scale to 0.1 (mm/s) and then
halui.max-velocity.decrease to 1.  That made halui.max-velocity.value
change to 53.2 mm/s, and the Axis Max Velocity slider changed to
3193.9 mm/min, which is also right.

I also tested with halui.max-velocity.scale set to 10 mm/s and 100 mm/s,
and both worked as expected.


I also tried on an inch machine with both linear and rotary axes, and
while there's only controls for max linear velocity, that config worked
as expected too.

Re: [Emc-users] halui.max-velocity ...

[giorgio foga]

Very thanks,


I just setting the [TRAJ] and [AXIS]  and [JOINT] section with the right unit 
per second  and axis gui work as I aspect ...  ... everything works well in 
axis gui, max-value is shown as I expect. The problem is only when I want to 
use the commands halui.max-velocity.scale / increase / decrease  at this 
point the value immediately goes to 60.0 ... and then if I use increase / 
decrease change correctly but never beyond the 60.0  at this point i try to 
move the slider axis gui and everything returns to be shown properly. I used 
google translate in hopes of being lighter. []   any how I control again 
my setting.


regards

giorgio
