Re: OSHPark and gEDA/PCB
I have sent artwork from PCB to OSHPark and received exactly what I sent
them. Problem being exactly what I sent was ... wrong. There were no
circuits on the back side due to me not paying attention to the files I was
renaming. As to OSHPark vs some of the Chinese fab houses (iTead, Seeed),
it really depends on board size. If the best you can do is 2" square, go
with the overseas fab houses. If you are after dainty boards and don't need
a boatload, go with OSHPark.
I am not thrilled about linking to this info, but,
http://letsmakerobots.com/node/37591 and
http://letsmakerobots.com/node/38709
might be of some interest. I scanned the first link and found the mention
of the bottom file not being what you want to rename, but rather, the
group1 file actually holds the image of the bottom traces. The second link
is a quick post about custom silk screen on the bottom of a board using PCB.

Re: [Emc-users] Desktops and OS's

[Kyle Kerr]

Way back at the start of this email, someone was talking about different
DEs. I personally have been running Bodhi linux, an Ubuntu derived distro,
for a few years. The lead Dev recently posted a blog about installing
moksha, an Enlightenment derivative, on Debian Jessie. Enlightenment does
things differently, but, it is quite light on resources. I believe
something like lxde is comparable.

Apologies for my reply. I was the stupid human posing the question. When I
read you only wanted the simulator, I thought I would ask why not just run
in a VM, but, I didn't ask in a text friendly way.

Re: [Emc-users] computing max acceleration for an actuator

[Kyle Kerr]

Late to the party armed with nothing more than book smarts, may not be
enough.
If you can accurately measure time over distance, you should be able to
find relatively close max accel. Once the time over distance is constant
from point to point you go back and say 0 to 100 took 500mS and 14mm or
whatever. Then you just do the math to find acceleration.

On Thu, Aug 27, 2015, 6:47 PM Dave Cole linuxcncro...@gmail.com wrote:

 If you set the max acceleration lower than
 the actuator is capable of, I assume it will work fine and just take longer
 to ramp up to full speed than it could in theory.

 Yes.   It will work fine.  You want the accel limit lower than less that
 what it can actually do.  Years after you set this up and things get a
 little gummed up,
 you don't want your actuator to be slower than what you command.   That
 may result in following errors and frustration.

 The same is true of the max velocity.

  Jerry I didnt answer your question.
  to measure acceleration there's an industry standard 'step' test.
  The 'step' is to apply the voltage required to achieve max velocity.
  This voltage **instantly** rises from 0 to the value needed for max
  velocity.
  Thats where the name 'step' comes from,
  Its a square edge on a scope.
 
  A second measurement is now needed,
  Some way to determine _when_ the
  maximum velocity is actually achieved.
 
  Old school dc motors gave us Tachos so this was easy.
  I dont know what you can put together.
  You could attach a voice coil to the end, I suppose.
  Measure when the output voltage goes constant ( at max vel )
  A scope should show a 'knee' starting at 0Volts.
 
  But if you measure time from the 'step' until the max vel,
  you have the precise acceleration _time_.
 
  The acceleration time divide by time is the acceleration
 
  ( example  .240 Sec accel time to achieve 800mm/minute velocity
  is .24 sec to achieve 13.333mm/sec
  is 55.555 mm/s/s
 
 3.15/sec  / 0.02ec = 157.5in/s/s )

  The actuator is rated a 3.15 inches per second and it can reach full

  in under .02s for the load I will be putting on it. If I use a = v/t,
  this

Re: [Emc-users] My crashomatic lathe box, update, sorta

A bit off topic, but, I noticed you, Gene, retyped the same command after
sudo. I'm unsure when it was added, but, you might try sudo !! to rerun a
command as root that you previously tried running as a normal user.

 Left shift? Untested but will be. With only a gig of dram, memtest+ v5.01

 Sometimes, it can take weeks to discover the error. I've tried changing

  I have a question about the voltage to drive a stepper motor
  12 volts works but higher voltages make the motor weaker
  I am building a simple stepper driver
  A nema 23 2.7 amp stepper motor and 36 volt power supply
  The controls are hand held, forward ,reverse, stop, and speed
  I built the controls and driver using a 12 volt battery to test
  Now I completed the project and am using the 36 volt supply
  The motor runs at the same speed but it is so weak I can hold the
  shaft and stall the motor This is also the same with 36 and 24 volt
  batteries
  With a 12 volt battery I can not stall the motor
  I am using http://piclist.com/techref/io/stepper/SLAm/SLAm_bld.htm
  and an Arduino I would be happy if someone would point out my
  stupidity
 
  The chip uses a constant current setup using PWM. When you raise the
  supply voltage then the trip-current is reached sooner and recovery
  may take too long for the next PWM cycle.
 
  The datasheet says that the off-time is between 7 and 12
  microseconds. Your high voltage level may cause a feed-through on
  the current-limiter because of the increased rising flank of the
  current. This decreases the on-time vs off-time and the effective
  current to the motor is reduced which results in a lower torque.
 
  The problem may be in the physical setup, where too much noise is
  propagated. You should check the wiring and use an oscilloscope to
  check the signals for spikes etc..
 
  I do not have an oscilloscope
 
  You may have to cultivate a friend who does have one.  As a scope user
  myself since 1951, there is no other way to measure things where time vs
  voltage or amperage needs to be measured.
 
  and I don't think noise is the problem
  I am single and it is usually pretty quiet around here :)
 
  The noise being refered to is electrical, not acoustical and steppers,
  with their built in PWM modulation in a decent driver that does regulate
  current to maintain the average, is one noisy puppy electrically, which
  is the sort of noise being referred to.
 
  One more question though. After half an hour powered up on 12 volts, how
  does the motors temp (its gonna be hot, use an IR thermometer) compare
  with 1/2 hour powered up on 36 volts?  If its smell it hot in 10
  minutes, pull the plug, your drivers are not regulating the current
  adequately and the motor is saturated, possibly damaging the rotors
  magnetism forever  If its many degrees cooler, then the driver may be
  turning itself down to protect the driver.  If its smart enough, most of
  the lower cost drivers aren't. I have let the magic smoke out and broke
  the mirrors on quite a few allegro A-3977 based drivers. I switched to
  2M542's off fleabay about 5 or 6 years back, buying enough to switch
  them all out with one spare for the parts drawer.  Its still there, has
  not been needed.
 


 No IR thermometer
 I ran the motor on 12 volts for about 1 hour and the chip was only barely
 warm to touch
 Then I ran the motor on 36 volts for about 1 hour and the chip was only
 barely warm to touch
 The 36 volt power supply is close in the same container so I disconnected
 it and ran the motor on batteries
 Same results the motor is very weak

 Someone mentioned xorg.conf, but I could not find any xorg.conf files in

 in this or a recent version of Debian by something else and confuses me.

 One person had the same issue and he got to this directory:
  $HOME/.e/e/config/standard and found files such as:
  e_randr.cfg plus e_randr.1.cfg thru e_randr.9.cfg

 Here's the page for that guy:

 not I got that right.  I issued:
 sudo su
 cd root

 But,
 ls root  --  there are no files or folders.

 I tried:
 cd .e
 cd e

 But, no surprise that folder is not there.

 I guess my question is, did I get to root, and if so, how can I get to .e

Re: [Emc-users] I love linuxcnc

[Kyle Kerr]

Wireless connections just require a bit of research. You may need to do a
bit of incantations in the terminal, but, it is likely your wireless can be
made to work. Worst case you find a wireless adapter known to work and go
from there.

 Hooking thgem up to the local network is almost a requirement as there are
 often several updates to the system as a whole at 2 or 3 day intervals.

 I do not of course know how your home network is setup, but I long,
 decades ago, set my network up on an abitrary address someplace in the
 192.168.xx.xx block.  This address range is NOT allowed to go through a
 router that s/b the first thing your modem, cable or DSL sees.  From that
 point it feeds an 8 port switch so I can have cat5 to several places, like
 to this machine, and to the two machines in my tiny shop building in the
 back yard.

 Setting it up can be daunting for someone used to a windows connect
 directly to the modem, but I consider a router with enough memory so a
 reflash with something like dd-wrt to be a basic requirement from a
 security standpoint.  Then it handles all the translations from your
 address, and Native Address Translates (NAT) between your outside address,
 and your local net, on a one way basis. Its 2 way, but with the provision
 that you can initiate a connection to cnn.com and it keeps track of what
 your machine asks for and allows the response from cnn.com back into your
 browser.  But even if cnn.com knows your address, it is only the outside
 address, and attempted access by cnn.com when you did not request it, will
 be refused. So its best of both worlds.

 There are several people here who can guide you in doing this if
 interested. Folks probably more familiar with it than I and who have
 better memory than I.  At 80, I think I am the senior member of this
 group, and the wet ram is beginning to show the effects of being a senior
 citizen and retired for a decade and change.

It has been suggested in the IRC channel that I try a magnet link instead.

magnet:?xt=urn:btih:021D79BDDE84BC272A9F714F74F822BC7C237800dn=ubuntu-10.04-linuxcnc1-i386.isotr=udp%3a//tracker.openbittorrent.com%3a80/announce

 Thats how ours is done, when the saw gets down there it flips the toggle
 switch off,
 when you want to turn it back on you flip the same switch to on

So, it is like the most useless machine, where one flips a toggle and
then it immediately shuts itself off? The difference being that the
saw is a useful machine.

I have to second Brian's suggestion, especially on AMD systems. Do a

10.04 in stock configuration. I have a system or two that require
NOAPIC and/or NOLAPIC(sp?).

You won't like Wildblue at all. Unless you can get some kind of decent
price/speed with cellular, you should stick with Hughesnet. At least
if you go over you get a free renew token every month to allow you to
get back to full speed. Wildblue has nothing comparable and if you
happen to go over a week into your month of your bandwidth cap, which
is limited up and down, you will be screwed for a month and get to pay
full price for a month you couldn't even use service.

@Ian, the satellite service in the US is terribly expensive for any
kind of speed. I pay $80/month with a 475mb download cap on a 1.6 meg
d/l connection.

 That must be in a newer version than the last one I had installed, about a

 Thanks Kyle.

From what little experience I have had with it, everything seems to
function, but, it can be unstable at times. It saves regularly, so,
when you restart the program you are pretty much back to where you
were when it crashed. The instability is not limited to an issue with
running in wine either.

I hope that helps with your choice.
