Re: [Emc-users] How to install custom kinematics module in sim-onlyLinuxCNC

[Javier Ros]

Viesturs,

Its a long time since I work in my kinematics, but from what I remmeber I
didn't need to do anything
special to work on simulation mode. So I think what you propose is the
correct way.

Good luck,

Javier

The encoder counter would need to compensate. it isn't too hard,
because the counter knows when to not expect a tooth.

The system has been used in car engines for decades. That's hundreds
of millions of vehicles doing hundreds of  millions of revolutions. I
can't think of many things that have ever been quite so thoroughly
tested.

[Emc-users] OT: Desoldering station minor repair

[Mark Wendt]

I've got a Hakko 472 that "Just Works" tm.  However, it has one little
really annoying trait.  The transformer "moans."  By that, I mean, it
doesn't have a steady hum, but more of a "w, w" in deep bass.
;-)

Would I be looking in the right direction were I to assume one or more
of the filter caps is starting to go?  If not that, anything else I
should look for?  No schematics of the board, so I'm shooting a bit in
the dark here.

Thanks,
Mark

Okey doke.  Will do.

If they're lose, what methods do y'all suggest for "snugging" them
back up?  Varnish?  Epoxy?

Re: [Emc-users] power supplies

[Dave]

It is hard to beat a properly sized linear power supply for reliability.

The cost difference compared to a switcher is not that great.   However, 
I've used both.

For big switchers, I have bought several from this company:

http://www.powersupplyemporium.com/

It is not obvious from their website but they sell thousands of 
different power supplies.

They really make you look to find the products.

For instance:

http://www.powergatellc.com/enclosed-with-fan-power-supplies.html

I've purchased a few Meanwell 1500-2000 watt power supplies to power 
stepper drives on specialty machines and they worked fine.  I would have 
used a big linear but I didn't have the space.

I was able to stack up three of these power supplies and fasten them to 
the cabinet backplane to minimize space.

The Meanwell power supplies are Chinese made.  I first saw them being 
used by a high end OEM near me a few years ago, and I have never had any 
problems with them.

This same place also sells DC-DC converters at the lowest prices I have 
found.

They also sell Din rail mount power supplies for significantly less than 
Automation Direct.

How does the car controls handle the possible partial reverse rotation 
of the engine when it stops?  Is it just ignored and the timing for TDC 
is close enough on the next crank that it doesn't matter, then
they resync when the missing tooth is found again??   Or do they sense 
the engine speed going to zero and then accelerating and declare that a 
reverse rotation instance on an engine stop?

Because the pulse width is the direction signal, and the rep rate is the 
speed, that does sound like a whole new component to me.

We are, generally speaking used to the quadrature mode, where the condition 
of one pulse on the given edge of the other, is the direction.

This would seem to need a timer counter, that for software convenience 
sake, would probably need to be married to the BASE_PERIOD.  On slower 
boards, this could be a problem because its pulse widths are a bit noisy if 
you look at the pdf sheets. For fwd rotation, the tolerance is 38-52 u-
secs, while the reverse is 76-104 in duration.

The speed part is relatively easy, how many pulses in a SERVO_THREAD 
interval, which should probably be averaged over several intervals with the 
lowpass component for slower speeds.

For those of us using the D525MW boards which seem to be pretty happy 
running at 23 to 25 u-secs BASE_THREAD we can probably say that a 1 count 
or 2 is fwd, and a 4 count is reverse, leaving a don't change deadband at a 
3 counts.  With finer timing of coarse we can likely get pickier, primarily 
because if its turning even at .25 rps, it sure isn't going to reverse in 
one BASE_PERIOD.  So I think I would nail the dir to whichever rail, until 
a very slow speed has been detected.  A speed at which its possible it 
could actually have been told to reverse.  Consequently I see the direction 
detector essentially frozen in place as long as the speed precludes its 
reversal without using hoover dams output for 20 microseconds to achieve 
the reversal.

In any event, it will need a separate index pulse, used to make sure there 
have been no missing or extranious(sp) pulses since LinuxCNC tracks windup 
with very wide counters.

I can't code it, not on these machines (I could on a TRS-80 Color Computer, 
but its clock is 1.79Mhz=max speeds in the 1 rps area, but first I'd have 
to cobble in a parport & write a driver, it doesn't have one), but I think 
that about covers it.

Humm, wierd thought about the reversals.  Is anyone here using a big 
honking frame 56 or bigger stepper to turn a lathe spindle?

What you may be hearing is the pwm beat that regulates the tip temp.  Does 
it change if you sink the hot tip into a puddle of solder, cooling it?

Hi Gene,

Nope, no change.  It's a moan that lasts for about 2 seconds or so,
stops, then repeats.  It seems to start a little after the iron gets
up to temp.  And like I mentioned earlier, doesn't seem to affect the
operation, but the sound is just annoying.

Most 'epoxy's today are way too fast acting, and won't sink into the 
lamination gaps fast enough to fill them before it sets.  I'd try a slow 
'spar' varnish & give it a week (or more) to wick in and cure before 
applying power again.  The superglue's wick well unless 'gel' but they have 
a relatively poor survival compared to well cured varnish if the core gets 
too hot.

I am not sure this is necessarily true.
LinuxCNC only typically _uses_ the index pulse when the spindle is
running at a constant, non-zero speed.

(this style of encoder is probably not appropriate for homing a
servo-driven axis).

Tracking reverse rotation is the whole point of these
direction-sensitive devices.

Before stop-start the system would have to wait to see an index to
figure out where TDC was.

I've got some laminating epoxy that requires well over 24 hours to
cure, and has a pot life of about three hours at room temp.  I suppose
I could thin the epoxy with a bit of either DNA or acetone to allow it
to wick further, but the that epoxy consistency is right about the
same as a good, thick cuppa hot chocolate, so it should be able to
penetrate fairly well.

On the other hand, I use true spar varnish all the time when I finish
the bamboo fly rods I make.  And I have a bunch of that laying around.

Thanks!

[Emc-users] New guy introduction and some questions....

[Pete Matos]

   First off Happy Thanksgiving to all of my EMC/linuxCNC friends.  I am
kinda new around here with EMC and I recently bought a used Cincinatti
Arrow 500 VMC for my shop. Initially the hope was to be able to fix the
original control and get it running. UNFORTUNATELY after several thousand
dollars were spent I had a few more failures of the original control
components and decided to just stop the bleeding here. I started looking
seriously into retrofitting the machine here and happened upon a couple
fellows who already have Cincinatti VMC's running under linuxCNC control.
After speaking with one of them and hearing good reviews I found my way
here.

My plan is to literally start over with this machine for the simple
fact that I do not trust any of the original components. Therefore I have
gutted the electronics cabinet of everything with the exception of the
original relays and the main on/off contactor rotary switch.  The only
things remaining of the original control are going to be the main spindle
motor, the toolchanger and power drawbar pneumatics, and the limit switches
and home switches.  I plan to purchase completely new motors and drives for
all three axes and I am seriously looking into the Teco models. These are
130mm 1000 watt 2000 rpm  4nm motors on the x and y and 6nm on the z axis.
I have already purchased a brand new Intel Atom D525 motherboard, a solid
state hard drive 90gb, 4gb ram, a brand new 15.6" widescreen monitor for
the control pendant as well as a sweet industrial waterproof/debris proof
keyboard.  Just yesterday I purchased the Mesa Electronics KIT with the
5I25 and 7I77 analog drive boards and cabling.

   The machine's electronics are substantially based on a 110v control
power setup for the relays and pneumatic solenoids apparently from what I
hear talking to Lee who has been so kind to share his experiences
retrofitting the same exact machine with the same exact control.  I hope to
be able to learn from you guys here about what it takes to perform this
retrofit. The intention unless I am advised otherwise is to run the motors
and drives under an analog 0-10v control setup and use the original relays
that appear to be in good shape to switch the 110v pneumatics for the
toolchanger and power drawbar on and off as needed.

   My initial GOAL is to get all three axes working with the limits and
homes setup  and get a temporary pneumatic setup working for the power
drawbar so I can use the machine WITHOUT the toolchanger initially.
Eventually I hope to implement a ladder logic setup for the toolchanger to
get the entire machine working as it did originally only better.  I am
looking for advice here about how best to approach this challenge and what
steps to take and in what order. Right now over this thanksgiving weekend I
hope to be able to start mocking up the new atom main board inside the
electronics enclosure and figure out what will go where. Not sure if I can
post pictures here but a picture is worth a thousand words I always say and
it would be nice to show what I am doing and how and my hope here is to
lean on you knowledgeable fellows and receive ideas and guidance about this
most elaborate build I have ever attempted.  Anyways, just saying hello and
I am hoping to hear from many of you and again Happy Thanksgivingpeace

Pete

I'm guessing that it's not a steady hum because the tip is regulating
around the target temperature and thus is not always on -- when you first
turn on the iron, does it hum continuously until it reaches temperature?

We currently have a requirement to fire on the second TDC (of a 4-cylinder)
That's less than 180 crank degrees.

An alternative might be to swap just the solenoids on the valves and
control with 24V direct from a Mesa card.

Joseph,

There's a very quiet and steady hum until it gets warmed up, and then
once it reaches the set temp, the moaning gets quite loud and
annoying.

That might work but I haven't seen anything like the epoxy I used on Bertha 
back in the 60's.  Sold as water ski finish, clear as water & left that 
laminated walnut looking like milk chocolate, good enough to eat.  18 coats 
of it at the time, took around 8 hours at 125F in an old fridge to cure 
each one, hit it with a piece of  steel wool so the next coat would 
stick.  Repeat till tired of it, let cure another 72 hours to really harden 
up, then polish on the power buffer just like a piece of steel.  Other than 
aging yellow, its been a great finish & has ridden probably 250,000 miles 
standing floor plate down across the transmission hump, against the front 
of the bench seat in many a vehicle over the last 45 or so years.  More or 
less out of sight, handier than sliced bread.  Many a deer has stood there 
watching in curiosity for the 10 seconds or so it took me to stop, swing 
open the door and slide out, trailing it behind me using the scope for a 
handle, rack a shell in and draw a bead.  Dinner (yum) got a free ride 
home. ;-)

Re: [Emc-users] New guy introduction and some questions....

[Pete Matos]

Andy,
funny you mention the 24v supply. The machine came with one and I am
trying to determine if it is usable now with my intentions to run entirely
on single phase. The solenoids that are in the machine are actually quite
nice and 110v control voltage is as far away as the wall around here so I
am thinking either would be suitable and the 110v setup might be less prone
to noise issues altho the 24v control is industrial standard from what I
gather.  I am currently trying to wrap my head around where to mount the
computer setup which will be entirely open and hard mounted inside the HUGE
electronics cabinet. I did remove a large U-shaped sheetmetal bracket that
was mounted on the top of the enclosure upside down that I may reassign to
computer motherboard,power supply, harddrive mounting duties.  I am
thinking it may allow me to be a little clever about the way I run the
control wires from the mesa cards to the new drives and back.

   I am anxious to get the mesa cards and apparently I MISSED a signature
required fedex shipment yesterday and may not be able to access it until
friday or monday.  That is PROBABLY me new mesa cards altho it might
actually be the solid state hard drive and memory cards I ordered too..  I
am going to be wading into rather deep water here learning how to configure
the mesa cards as well as learn my way around linuxCNC too.  I SINCERELY
hope I have made the right decision here. I mean this machine is not a toy
to me, I fully intend to run the piss out of it once it is running. This is
not a hobby anymore and I hope to be able to make some good money with the
resultant machine and that will rely heavily on the choice of components
and the operating system's capability and reliability.  I guess time will
tell... peace

Pete

pastebin.ca, setting about a week or less expire, then post the link to it 
that pastebin gives you to here.  Stuff I put on my own page tends to not 
expire & then gets stale. :(

That sounds more like a finishing resin rather than a laminating
epoxy.  Finishing epoxies have little to no solids in them, since
they're designed for presentation and for making the surface pretty
much water proof.  The yellowing you see in most laminating resins is
due to the solids in solution to get the characteristics they're
looking for in a laminating epoxy,

Gene,
Hey man nice to meetya!  I guess I can post the pics to my photobucket

a photobucket folder for all the Cincinatti arrow pics. HMMM  something to
consider.  Peace

That all fits it to a T Mark.  I don't even recall the brand name after all 
this time & its likely moot anyway.  I have looked a bit at the local boat 
shops without finding anything that resembles that stuff at all.  Mostly 
all they have in Marine rated paint.  When I refinished the bottom of my 
boat about 4 years back, I bought 2 quarts of Oliver Tractor green from TSC 
and the hardener additive that makes it cure in about 4 hours & put at 
least 2 coats, high wear places 5 or 6 on it.  It seems to be a very tough 
finish, not seriously damaging it running into a pebbled beach at 1 or so 
mph many times now.  Thats a heavy (900 lbs) old honk, a '68 Terry Bass 
boat, and my 9.9 Yohnson only makes about 6 mph on the GPS with its tongue 
hanging out, no floatation so it would go down like a rock if I ever holed 
it.  Makes a great trolling rig. 

And I'm sorry to say I was otherwise busy this past summer and did not even 
get it wet.  Shame on me, 500 lashes with a wet noodle or something. :(

I will likely be around till I fall over, I'm sort of the resident old 
fart.

78yo, mostly retired tv CE, an EE without the paper on the wall.  Many of 
these folks have helped me, so if I have any experience that applies, 
you'll probably read me again.

I'll likely gain a little weight today, the missus is fixing Cornish Game 
Hens with the usual T-day surroundings, something I probably shouldn't do 
as keeping the weight down is one way to semi-control type 2 diabetes.

So have a happy T-day yourself if your folks celebrate such.

Those epoxy and other 2-part finishes are quite durable, that's for sure.

You and me both.  I didn't even get around to de-winterizing my little
18 1/2 yacht this past year.  Never once got to drop it in the water.
Even the fishing was the bare minimum this year.  Just too damn busy I
guess.  Will definitely have to fix that next year.

Re: [Emc-users] New guy introduction and some questions....

[Pete Matos]

Gene and Dave,
 I have been looking all over for the information I need to do this. I
guess my plan is to take it one step at a time and one circuit at a time
and hope for a good result.  Again the initial hope here is to get the
basic machine working and then worry about getting fancy with the
toolchanger and a later fourth axis and probing down the road.  The mesa
cards seemed like a good fit based on reading some others successes with
large pieces of equipment.  I think Lee's machine is of course the most
specifically related to mine in both the base machine as well as how he did
things. The problem there tho is that he is in England and has three phase
power available and has kept some of the controls input electronics to
allow him to use that whereas I have a very nice three phase converter here
that I intend to wean myself off of and go strictly single phase.  The rest
of what he did tho is quite interesting and works well for him. The only
thing he did that I am hoping to avoid is NOT doing a true control setup
for the toolchanger. He basically does a kind of G-code control as I
understand it of the toolchanger command.  I hope to setup the toolchanger
as it was from the factory and be able to run it both directions etc...
Other than that his machine seems brilliant and he is saying that he is
getting some very good accuracy and reliability from it altho it has not
been running very long.  Here is a link to his nicely powdercoated and
finished machine running, hell he even was able to institute the use of a
pro-renishaw probe. I sincerely hope to be where he is in the near future.
Peace

It actually gets fairly complicated!  To handle the missing tooth, you 
need to have
a tracking counter (or whatever) that keeps track of the recent time 
between pulses,
so it knows how long a gap is going to be the missing pulse.  When the 
instantaneous
change in velocity is large, like at spindle reversal, then you are 
likely to miss
one of those pulses.  So, my guess is it can work well for a lathe 
spindle running
at nearly constant speed, but may not work well at all for rigid 
tapping.  I'd be real
skeptical it could work at all in that case.  Also, with a range of 
BASE_PERIOD
timings, detecting the 45 vs 90 us pulse width might be a bit tricky.  
If used on
a fast machine with a 20 us BASE_PERIOD or less, it should be fine.

Generally, I just don't see the advantage of going to a single 
sensor/single wire
scheme when there are so many potential pitfalls.  Anyway, it would take 
some
serious work to make sure this is completely reliable.  Most parallel 
ports have
5 input lines, so that should be enough for the E-stop, limit switches and
leaves 3 for a quadrature encoder.

One other comment, with a 90 us pulse width from the sensor, and 
assuming some
reserve, so assume pulses should never come faster than every 180 us, that
is 5556 pulses/second.  If you assume a gear with 100 teeth, that is
55 RPS or  RPM.  So, this should work on most lathes with up to
100 tooth gears on the spindle, but might be a limitation on small mills.
(Well, they might have fewer gear teeth, anyway.)

Could be, but it may just be the effect of unbalanced transformer flux 
from the
SCR control.  If they have the SCR/Triac on the primary of the transformer,
then this is almost certain to unbalance the flux.  Has it always done this?
If so, my theory is probably right.  If it has only started recently, and is
getting worse, then it may be fading capacitors.

Well, based on the theory that he doesn't run the clock while you are 
fishing, I should be several years ahead, because I've sure done a lot of 
it.  A decade in the Black Hills, and 2 on the San Juan River in NM.  Yeah, 
that river.  The place the outdoor raqs talk about in the middle of their 
orgasms, yup, I've fished it, its about an hour upstream from Farmington, 
that 3 or 4 miles below the Navajo Dam.  Both places are paradise for a 
fisherman.  Here in WV, not so much, the water is too warm for trout & 
walleyes.

Humm, I think I can get that from Grizzly.  As I have a BP about finished 
I'd like to armor a bit better than the Sams Stuff that is on it now, when 
I am truly happy with the wood, I'll certainly check that out.

Thanks Steve.

good stuff. I use it for laminating wood for gun stocks. IIRC 5:1 ratio

The single-wire is just a side-effect of using an encoder wheel that
is readily available and has a big centre bore.

To buy the crank code-wheel new is not that cheap ($100) but there
ought to be many in the junkyards now. The correct pickups are less
likely to exist, but those are $17.

[Emc-users] PNCConf + 5i25 + 7i76 configuration failure

[Stephen Dubovsky]

Hello all, we get a Gerber Dimension 200 Gantry router converted today w/
the help of my dad and brother.  This is the first time I've used a 7i76
and it seems to be generating a bad ini/hal file?  We installed a clean
2.5.1 and get the following error when trying to start LinuxCNC.  PNCConf
can jog the axis back and forth in its built in test so the hardware seems
to work.  I can't make sense of the errors.  There are no MOT, IO, etc
sections in the ini file.  Can anyone help?

Thanks,
Stephen

Both slow and fast hardeners proclaim they are not for clear coating.  Is 
there a reason?

Or is that from whence the age yellowing comes from?

Seems to me the 105 is probably useless without the hardening catalyst.

I had to search for it, the link is intercepted at the front page.

Usage info they are holding confidential until you read the label on the 
product once you have had it delivered.

Since the requirement is that its ferrous, I seen no reason that can't be a 
milling machine project.  Depends on what one thinks his time is worth I 
suppose. :)

The Allegro ATS667 series are about $6 each, but you need 3 for a 
quadrature+index
scheme.  But, the advantage is you can use any available steel gear on 
the spindle
as the encoder wheel.  That's what I did on my Bridgeport, used the 
existing bull
gear inside the head.  I made a small dimple in the gear for the index 
pickup.
This turns into a 324 count/rev encoder (81-tooth gear * 4 in quadrature.)

Please post you .pncconf file.
And I will try to duplicate the error.

Hi Stephen

I see you selected 7i76x1 for firmware.
This is a trick firmware name I set up that i think has back fired.

Please try this experiment.
select 7i76x2, you may need to select the axis again.

If it works there problem is Pncconf forgot to turn the sserial ports on 
that the 7i76 needs.

After another look I see you seemed to have set the number of serial ports
to 0 - it must be set to one 

If you do that then 7i76x1 should work fine.
