Re: [Emc-users] XHC-HB04 on LinuxCNC

[Danny Miller]

OK, what I have is:
1.  xhc LCD reads coords
2.  xhc moves axes slowly in Joint mode, the selector knob sets the axes.

What doen't work:
1.  xhc has no effect in World mode at all.  Either the XYZ page or when 
you select MDI.
2.  The step speed has no effect even when it does step, in Joint mode- 
I can't speed it up.

Re: [Emc-users] OT: LED driver

[Chris Albertson]

Today if you want to drive a bright LED from AC you can go to Home Depot
and buy an Edison base LED light bulb for $5, screw it into a standard
light socket.  The constant current DC supply is built into the base of the
bulb.

You would think that an outfit should understand by now that a snappy com 
presence, and somebody to answer the phone would be the two most 
important aspects of the face they present to the potential buyer of 
their products.

Go figure, I can't with what little data I can find, it simply doesn't 
compute.

You, as a gear maker for us as Pico Systems, understand that, and have 
given me more help and support than I expected for the first of your 
products I ever bought, and if I was to get the contract to make 20 of 
these conversions that used your pwm servo driver, you'd have the order 
in your inbox the next day, for 22  of them.  Its a great product, with 
one small gotcha, its apparently bulletproof!

Digi-Key sells over a thousand models of LED lighting power 
supplies.  I used a fairly expensive one in some fluorescent 
retrofits, made by Thomas Research Products.  They seem to 
now have units for about half that price.  Just look up the 
current and voltage you want.

This is not a function of the editor, it is a function of 
the shell configuration.  I haven't worked with this, but 
apparently, umask is the variable.  I think new OS's have it 
in /etc/login.defs
You can also set this for each user in file .bashrc in each 
user's home directory.
The value is the numeric valuse of the default file 
permissions, in octal.

Some Google searching about umask should come up with more info.

I've used ledsupply in the past as well.

Here's one that should fit.
http://www.ledsupply.com/led-drivers/phihong-pda025w

They were probably seeing 400ma each before. If you got the 750ma they
would see 375ma. A little less bright I suppose. You could always go down
to the 450ma but then they would see 225ma and that would be about half the
output.

I've been happy with DC input LED drivers from ledsupply.com.

No reply on the candlepower forum, but nearly 100 views of the post I made. 
Since that forum is all about LED lighting, I expected someone to have a 
suggestion.
I have a couple of LED motion detector lights, each with two Bridgelux 
BXRA-56C1000-A LED modules. Nominally rated at 1000 lumens each.The motion 
switch is a self contained 110 VAC switch, so all I need are replacement power 
supply/drivers with 110 VAC input which will fit within the lamp bases.
The original supplies went *poof* but the LEDs are still good. They are in 
large die cast housings that provide ample heat sinking, but without any 
compound between the aluminum LED star plates and the bare metal mounting 
surface, so I'm putting some compound on.
Available volume in the base is about 4.25" diameter by 1.25" depth.

The output connection on the dead supplies in the lamps are marked 800 ma 35 
volts. At that power, the lamps will put out enough light to brighten a wall 20 
feet away on an overcast day. I don't think I need quite that much light in

Re: [Emc-users] Way OT: Cannot see Workgroup Computers

[Gregg Eshelman]

Are you manually assigning IPs or are you using DHCP?
There must be only one active source for DHCP on a LAN. You can use more but 
only if each one is serving IPs for different private IP address ranges. A DHCP 
source must be always on, or be turned on and ready before the systems it's 
assigning IPs to are turned on. So if your router is the DHCP source and you 
turn it off, your computers, printers etc can lose track of one another.
Another method of not manually assigning IPs on each individual computer or 
other devices is with a BOOTP server. From a central source you can assign IP 
addresses to MAC addresses. 'Course you then need a BOOTP server process 
running on an anways or first on computer, or a router/modem with BOOTP 
capability - and you get to type in a bunch of MAC addresses.
For my little LAN I manually set the printer's IP addresses but let the 
internet router use DHCP to assign IPs to the computers since I'm not currently 
doing any file sharing among them.
I also set the printers to high numbered addresses like 192.168.0.186 and 
192.168.0.192 so that the DHCP won't do stupid things like assigning a computer 
the same IP as a printer. It starts at 192.168.0.2 and increments the last 
number up from there. 
In my experience with Windows and networking (going back to version 3.0), 
Windows has an issue with forgetting where printers are when they have 
dynamically assigned IP addresses. Newer versions of Windows have a "dynamic" 
network printer option that's supposed to get around that but I haven't tried 
it. Setting a fixed IP and installing drivers for each printer on each computer 
works and stays working because it's not allowed to be altered by the whims of 
software.

 Subject: [Emc-users] Way OT: Cannot see Workgroup Computers
   
In know this is way off topic, but if anybody would possibly know, I'm 
sure they are floating around here somewhere,

We have a small network here at the shop, roughly a dozen PC's and 4 
CNC's ( my linuxcnc builds) that are all networked together, using a 
workgroup type setup, not a domain. Most of the time everything works 
fine, but randomly ( right now) when you try to look at one of the other 
workgroup computers, there is nothing there. On my wheezy machine I 
clicked on the "Network" selection, and then clicked on the "Windows 
Network" link, and there is nothing there. So I went back to XP machine, 
and went and clicked "View Workgroup Computers", and a popup box comes 
up after about 10 seconds that says " The list of servers for this 
workgroup is currently unavailable". On both machines, I can access the 
internet just fine, I pinged the wheezy machine from my XP machine, and 
everything looks fine there, so what could possibly cause it not 
see/display the other PC's in the network managers of either machine?

Which tells me they need an active enable, so hook the 5 volts to the + 
terminal, and something that goes to ground when LCNC is enabled to all 
the - enable terminals.  Or, just hard wire the - enable to ground them 
& leave them on.

[Emc-users] OT: LED driver

[Gregg Eshelman]

No reply on the candlepower forum, but nearly 100 views of the post I made. 
Since that forum is all about LED lighting, I expected someone to have a 
suggestion.
I have a couple of LED motion detector lights, each with two Bridgelux 
BXRA-56C1000-A LED modules. Nominally rated at 1000 lumens each.The motion 
switch is a self contained 110 VAC switch, so all I need are replacement power 
supply/drivers with 110 VAC input which will fit within the lamp bases.
The original supplies went *poof* but the LEDs are still good. They are in 
large die cast housings that provide ample heat sinking, but without any 
compound between the aluminum LED star plates and the bare metal mounting 
surface, so I'm putting some compound on.
Available volume in the base is about 4.25" diameter by 1.25" depth.
>From the LED datasheet
mA Volts Watts Lumens115 25.3 2.9 395250 26.5 6.6 850350 27.3 9.6 1150500 28.4 
14.2 1580
The output connection on the dead supplies in the lamps are marked 800 ma 35 
volts. At that power, the lamps will put out enough light to brighten a wall 20 
feet away on an overcast day. I don't think I need quite that much light in 
front of my shop or on my back porch.

I wondered about that, as it does seem counterintuitive, but all of my 
2m542's are not enable wired, and neither is the DM860A.  They are 
enabled by default.  If those follow the crowd, and the - enable is 
going to ground when you hit the test button, its possible that that is 
wrong.  ONOH, if they need - taken to ground to enable, then the hal 
logic needs inverted...

This makes me ask if perchance, you are feeding the step signal to the 
dir and vice versa? In that event toggling the dir will probably make it 
step back and forth whatever small fraction of a step the microstepping 
switches are set to, and that could make a 1 khz tone w/o moving the 
motor more than a couple arc-minutes.

Thats the sort of thing I'd trot out an o-scope to look at just to 
confirm I screwed up ( don't ask me how I know ).  Since you might not 
understand what you are looking at on the scopes screen, I won't push 
that, other then to have you check, from the generated .hal file, all 
the way thru to the drivers inputs, that the signals haven't crossed 
each other.  There are several places that could happen, including 
the .hal file itself.

They are opto-coupled, and both ends of the opto device must be connected 
to the world inhabited by the BOB and its power supply.  And because the 
BOBs usually have a TTL output, they can pull 10x the current to ground 
that they can pull up to the 5 volt rail, so normally we feed the 5 
volts to the + terminals, and the control signal from the BOB goes to 
the - terminal of that input.  This give at least a 1500 volt barrier 
that only the light from the optocoupler can cross, preventing voltage 
spikes from destroying either the BOB, or the rest of the input 
circuitry in the driver.

One caveat:  Crossing that barrier can and will screw up the linearity of 
controlling a PWM controlled motor, so I've been forced to extract the 
opto's in the BOB before I could control the spindle motor at all well.  
They tend of have a much shorter turn on than turn off time.

With the drive inactive, meter that 5 volt line making sure its within .2 
volts of 5 volts.  Then read the - pins, which s/b effectively open 
circuited, and reading something in the 3.5 to 4.2 volts, dropping to a 
few tens of millivolts if you send it a signal to run at the high speed 
limit, say a 99% ON PWM signal, and since the logic is upside down, you 
will read a pretty low volage.

Looking further on the AT site, they aren't at all anxious to sell 
motors.  I did find an 1805 oz/in 2 motor 'kit', 2 motors, two of their 
drivers, a breakout board and a wall wart for it, presumably for a mach 
lathe setup.  6 Amp drivers so I assume the driver and motor are matched 
but I can do 6 amps with this psu.  But I'm not paying $700 + shipping 
for the whole thing when all I need is the motor, and maybe the 20x5 Z 
screw & its supporting hardware they also have in a G0704/BF20 
conversion kit.

And at 16:15 local EDT time, the phone number in Hoffman Estates, IL, on 
CDT so its 3:15 their time, is being answered by a voice mail system.

Does anyone have a better phone number than that one on their web page?

I know you all seem to think AT is the best, but when you cannot find 
what you want, AND they aren't answering the phone during what should be 
business hours, I am not being favorably impressed.  Frustrated is more 
like it.

The motors go dead when I unplug the enable.

You say all the + pins go to 5v. I just tired that using the +5v from the 
enable to connect to the pulse + and dir +, the controller dir to the dir - and 
the controller step - to the pulse - and still no dice. Is that what you meant?

Hi Gene,

Thanks for all the suggestions everyone.

Hmm, I think the one thing I do have wired up correctly is the enabled.

Because as it is the motor is off until I press the “Test Axis” button in the 
stepper wizard, then immediately holds its position under power (and makes a 
high pitch whine). If I unplug the enable, or close the Test Axis dialog, the 
motor goes dead. Why we are not getting the 2nd LED lit I have no idea.

I still am not sure why the driver has Pulse + / - and Dir + / -. I am 
accustomed to only a single pulse and dir. 

If I understand correctly, I just tried connecting the signals from the 
controller to the - pins and the +5v from the enable to the plus pins, but no 
luck.

Since I have wired this up based this a photograph (from someone that has it 
running with LinuxCNC in a video), can anyone point me to a diagram for a 
similar setup? Guess we will try contacting the author, see if he responds. In 
the picture shown, it looks like he is only using the Dir + and Pulse +, I 
don’t see any leads to the - pins.

Back on topic, playing some more with g33.1 vs Z motor settings.

First, I looked it up, it is a 1600 oz/in motor made b y Longs, rated for 
3.5 amps, but does not spec total or rms per winding in any of the pdf's 
I could locate online.  I had it set for 3.5 peak or about 2.5 rms.  I 
doubled the microstep rate which quieted it some, and ran the controller 
up to 3.5 amps rms.  Acidentally disabled the stopped current reduction 
so in an hours playing so its a good burn your hand hot now.  Found a 
different pdf that made it plain sw4 is inverted and that "on" shuts 
that current reduction option off.

Fine tuned some accels about 5 to 10% slower, found the backlash was 
now .00675", and recalibrated the z scale by about .05%.  That cheap, 
skinny 16x5 screw might get replaced quicker than I had planned on. :(

Went back to the dep hole in the air tapping with a 4mmx.7 virtual 
tap. While I did not gain any real Z speed, it did seem to be happy at 
41IPM & didn't upchuck until it had run quite a while ending with a z 
hitting the softlimit while it was still just touching the home switch 
on the upstroke, which tells me it was losing Z steps getting turned 
around at the bottom of the stroke, so it thought it was higher than it 
physically was. I was adding another 1% to the spindle revs about every 
other peck.

At quite close to 1400 revs, the overtravel at the bottom was around 1180 
encoder counts, or a hair over 4 turns to get stopped at the bottom of 
the imaginary hole.  It was one turn, 268 encoder counts at 500 rpms, 
and about 1/4 turn at 200 rpms.  Humm, those are subject to redoing with 
the backgear in low, but until I remember it, no clue if they'll go up 
because of the increased motor rpms, but its for sure they won't be the 
same.

I wonder, is there some way I could feed that count back into the gcode 
so I could mung it into a distance measurement using the interpretors 
math?

Displaying that result in a slider under the tach would be kewl. :)

No, you can have several. They should be listed in the [HAL] section
of your INI file.

The error sounds like you tried to load the same file twice.

Re: [Emc-users] Copying G code files from PC to PC

[Rick Lair]

I had to pull the SSD that has wheezy on it, and put them back onto the 
Ubuntu system, due to the problems with moving files around between PC's 
( the reason for this topic to begin with). Friday, the supervisor tried 
to copy a file out of the machine, back to his PC to look at the edits 
that were done during the day, and he ran into the permissional problems 
we have been discussing.

Now that I have the SSD with Wheezy on it, in my office, I hooked it up 
,and have been messing around with it to see what I could find. What I 
know is that, when I transferred all of the files onto this new SSD, 
everything "had" read/write/execute status for owner/group/others.Now as 
you open and edit these files, then save them, the permissions get 
changed to rwx for the owner, then read only for group and others. When  
I originally copied all the nc files to this SSD, I copied them using 
"select all", then copy, then just pasted them into the respective 
nc_files folder, then from the terminal I ran "sudo chown -R 
cinci12u:cinci12u nc_files", and also "sudo chmod a+rxw -R nc_files" to 
get the permissions set accordingly,

So how do I stop the editing from changing the permissions of the files? 
I tried a few editors (kate, gedit, mousepad) and don't see anywhere to 
set anything to stop changing these.

Now maybe, but my memories go back to about 1939 when I was 5yo.  And the 
1/8" "aircraft" cable I have 50 feet or so on a small winch, isn't 
stainless, and it has rusted some.  The winch is on one leg of a tripod 
made out of 16' 2x8's I salvaged from a big AFC sat dish crate 25 years 
ago. It has come in handy as a sky hook over the years, helped me turn 
my boat over so I could patch its bottom and give it a fresh coat of 
Epoxy green Oliver tractor paint, helped me build the garage in 2008, 
currently suspended for storage out of the weather from the ridgepole of 
a 10x20 pipe framed canvas garage with its up hill legs cut down to 
match the hillside its sitting on, firred up and now recovered with 
currugated plastic roof sheeting.  My 46 year old fishing boat sits in 
it along with a random selection of other yard and construction gear.  
That weight made sure it survived a measured 112 mph wind in 2010 that 
took down 3 of the 4 pine trees & severely damaged a 4th, all my board 
back fencing and quite a bit of the shingles off the house & damaged the 
rear siding enough that State Farm paid me for all of it.  I finally had 
the 4th one taken down last fall as it wasn't looking so healthy.  Root 
damage from me hitting it with the riders blades over the years.

That winch got heavy use when I rebuilt the fence after that 2010 blow, 
in green wet poplar using 3 native sized 2x4's 8 feet long for panel 
horizontal runners, with a 1x6 on each face of the runners, spaced 2" 
apart to let some air go thru but block the view. Green & wet when I put 
them together, each panel weighed 400 lbs. That tripod and winch lifted 
them into position to screw them to the 4x4 treated posts. Except for 
one panel that I assembled on the back deck to see how it would look 
that I collared 3 other neighbors to help me take it to where it went, I 
did it all by myself.

All told about 80 feet of fencing, with nearly 35 lbs of 2 different 
sized treated deck screws in the whole thing and I only used one Bosch 
phillips #2 bit putting all those screws in with a Hitachi 14 volt nicad 
powered drill.  I have since bought bags of other bits that looked good, 
but are junk in 20 screws driven.

Had a 2 week break in the middle, when I got to where I was going to put 
a big, double swinging gate in so I could get the rider & anything else 
its size thru to the back yard, Dee said it had to have an arch over the 
gate, so I re-read rule #2 & set the chop saw for about a 6 degree  
angle and made a 3 layers of 2 by arch out of little 6" pieces sawed at 
that angle, after I'd run it thru the planer for a more uniform 
thickness & laminated with tightbond III, & all the F clamps I had, 
setting the ends on some corbels from Lowes and "made" an arch.  Covered 
in a blond olympic stain at the time thats about gone now, its still 
there. No screws in it, just the glue holding it together.  The corbels 
are cracked and breaking up but the arch still looks solid yet.

Its all turned a weathered grey now, but my back wouldn't let me do 
anything but hire it re-stained or painted now.  If it outlasts me the 
way it is, and its looking like it will, shrug.

Cheers, Gene Heskett

Re: [Emc-users] Keep getting Following Error in World Mode

[dannym]

Shoot- you're right, I changed that!

Could you explain DEFAULT_VELOCITY and DEFAULT_ACCELERATION and MAX_VELOCITY 
MAX_ACCELERATION?

I thought MV and MA is the max vector sum.  That is, if X and Y axes have a max 
vel of 200, the MV in TRAJ has to be at least 283 to allow it to move that fast 
in tandem?

But what's the DV and DA? "The initial rate for jogs of linear axes".  What 
does "initial" mean, and how is it different than "maximum"?  I mean if I use 
"G0 X20 Y20", initially it's 0 and AFAIK uses the TRAJ and X/Y MA and MV to 
travel at max speed.  So what's "initally" mean?  Initially we're at 0 before 
starting a move.  The "DEFAULT_VELOCITY = 0.0167" (0.0167 listed as a default 
value for DEFAULT), what additionally confuses me here is if that machine 
unit's inches/sec or mm/sec, that's an absurdly small number to be jogging at, 
suggesting to me it's not what I think it is at all.

Re: [Emc-users] XHC-HB04 on LinuxCNC

[dannym]

What's this stuff about "missing wires"?I'm a bit confused what it's trying 
to use that isn't part of a basic config.  

So it is only possible to include one .hal file?  I have one already obviously, 
then the XHC instructions say to include this xhc_hb04.hal file, which threw an 
error about "duplicate hal file" or something.  I ended up copying the contents 
from xhc_hb04.hal into my own hal file, is that the intended solution?

[Emc-users] Way OT: Cannot see Workgroup Computers

[Rick Lair]

In know this is way off topic, but if anybody would possibly know, I'm 
sure they are floating around here somewhere,

We have a small network here at the shop, roughly a dozen PC's and 4 
CNC's ( my linuxcnc builds) that are all networked together, using a 
workgroup type setup, not a domain. Most of the time everything works 
fine, but randomly ( right now) when you try to look at one of the other 
workgroup computers, there is nothing there. On my wheezy machine I 
clicked on the "Network" selection, and then clicked on the "Windows 
Network" link, and there is nothing there. So I went back to XP machine, 
and went and clicked "View Workgroup Computers", and a popup box comes 
up after about 10 seconds that says " The list of servers for this 
workgroup is currently unavailable". On both machines, I can access the 
internet just fine, I pinged the wheezy machine from my XP machine, and 
everything looks fine there, so what could possibly cause it not 
see/display the other PC's in the network managers of either machine?

There's a sample config shipped with 2.7.4, called sim/axis/xhc-hb04.
Give that a try, then read the config to see how it was done.

Ours is just the same well-galvanised wire as used on the 7 km boundary
fence. There's a new blue-coated variety out here, apparently rated to
resist coastal spray. It might be worth a try, but in 52 years we've not
had rust problems with the plain galvanised variety. It doesn't take
long to change - compared to the decades of service.

Yeah, even the termites have trouble with that. But our poles last decades,
about 50 metres from the forest. (Wouldn't do nearly as well in there.)

Mind you, e.g. 1/8" stainless steel cable is pretty cheap at the
hardware store, especially averaged over half a century.

Every time you comment-out a line you lose a function. A much better
approach is to read the error message, work out what is different
between your config and the sample config, and correct the error.

As a first step, start the system up then open a terminal window

halcmd -kf
show pin

That will give you a list of all the valid HAL pin names in your
particular configuration. You can then check that list against the pin
names in the commented-out lines

My favourite is also rsync, but there is one thing to watch out for, if
backing up to unreliable media such as flash sticks. Some of them last
for years, with many writes, but I've had one which developed about 6%
corruption in less than 1% of files. Since neither the ctime nor the
size of the files changed, rsync did not detect the corruption.

By default, rsync finds files that need to be transferred using a "quick
check" algorithm which only looks for files that have changed in size or
in last-modified time. Safer is:

-c, --checksum
With this option, rsync compares a 128-bit checksum for each file that
has a matching size. That can slow things down significantly, but what
use is a corrupted backup?

[Emc-users] XHC-HB04 on LinuxCNC

[Danny Miller]

I do like this pendant.  I used it under Mach3 with mixed success- it 
was essential to have SOMETHING on a large router where you're away from 
the keyboard, but it was kind of a mess the way it responded (and the 
driver was closed-source).

Anyhow, trying to get it to work on 2.7.4, using 
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Using_A_XHC-HB04_Wireless_MPG_Pendant

Had the problem where HOME_SEQUENCE isn't specified, ok.

I did get a LOT of errors about pins either conflicting or not 
existing.  I'm confused but commented line after line out.

Right now it's moving it in Joint mode but only as single-steps, it 
won't do a large-step.   And it's not working in World Mode.

Has anyone set one of these up before?

Danny

I had to configure a tb6560 with nema 34 motors, like that:

step time: 1
step space: 1000
step hold: 1000
step setup: 1

however the wirings on the board manual were wrong, the *motor* manual
saved me.
