[Emc-users] Using an old Anilam control panel with LCNC?

2013-08-09 Thread Gregg Eshelman
I'm thinking of keeping the old control box on my mill to house the new 
computer.  I'd like to use the control panel, which on the Anilam Crusader M 
has 54 switches in the main panel plus a separate 8 switch panel. There's a 
couple of ways to go about that.

1. Remove the existing encoder and directly use the key matrix connector, which 
has 18 pins plus 6 pins that're all tied to a ground plane. The sub panel has 9 
wires so that's 9 separate switch leads with a single common. Could connect all 
that to a programmable switch matrix encoder and assign switches to match LCNC 
functions.

2. The stock encoder board has a 3 wire power input and a 4 wire interface. 
Unless the encoding it uses is documented somewhere, converting that to USB or 
PS/2 could be a challenge - and wouldn't do anything for the sub panel.

Some Google on the chips... KR9600 PRO is a keyboard encoder, capable of 
handling up to 90 switches. D3-6402R-9 is an RS232-C line driver. Ah-so! This 
board speaks serial!

Feed it power, connect to a com port, setup a terminal, poke buttons and see 
what gets printed on the screen for each one. Does LCNC support a serial 
connected control device where every input can be assigned as needed to program 
functions or normal keyboard keys?

Which would you think would be easier? Matrix encoder to USB or use the 
original encoder and translate its serial output?

The other thing I'd like to do is install a small LCD. If I remove the original 
bezel for the CRT I can fit up to a 9" diagonal 4:3 ratio LCD without making 
the hole bigger. Problem is I haven't been able to find such a thing, new or 
used. It doesn't need touchscreen or speakers or any inputs other than a VGA 
port. 800x600 could be a bit cramped on resolution but mostly that screen would 
just be for loading files and monitoring how it's running.

Thanks Steve, that got me thinking. :)
And as it happened I had some boring long term tasks at work today (load
testing of a distributed retail system) and some spare time when watching
the monitors and log files. So I took it further and sourced some of the
heavy formula's. I didn't go to the fullest, I have added a "default"
inertia for motor and reduction for example. But the calculations turned out
to be quite interesting and fun to play with so I updated the calc sheet
pretty much. Please have a look!

Re: [Emc-users] Thermocouple to LinuxCNC

2013-08-09 Thread Troy Jacobson
Changing to a thermcouple is a near future project for me, too.  The MAX
chip looks better for this application, especially since I'm looking at
nylon and maybe PC printing (300-320C range).

For this, the AD595 has a couple of issues.  First, the output for the
termperature range I'm looking at is 3 to 3.5v, which is over twice the
range of the BBB's ADC.  The voltage divider is easy, but by the time I've
added in a safety zone and add something to limit the voltage into the ADC,
it becomes more complex and results in lost resolution.  Also, the max chip
can run on 3.3v that the rest of my BBB uses.  The AD595 would probably
require something above 5v to measure the temps I'm looking for.

What I haven't decided upon is where to mount the converter.  Can the
thermcouple wire withstand the repetitive motion if the extruder were to
move relative to the converter (on the X and Z axis), or should it be
mounted near the extruder so that the thermocouple wire doesn't get flexed
at all?

With a thermistor, I used a simple 555-timer circuit to convert temperature
into a variable frequency:
http://www.anderswallin.net/2010/11/temperature-control-circuits/
It's very nonlinear and not that precise, but for 3D printer bed or nozzle
temperature control it works fine.
No ADC or other circuits required, one parallel port pin reads temperature,
another outputs PWM to the heater.

PS. for another project I am very much interested in real-time
SPI-connected ADC into HAL, so keep us posted!

Paul, a while back Jon Elson commented about lags between user input on 
the X11 server and resulting action in the X11 client, e.g., the LCNC 
host. I don't believe this is an artifact simply of your Windows-based 
X11-server lashup although this configuration could be a contributing 
factor. At the moment, looking at the latency issue remains stuck in my 
FINO (first in,never out) stack.

One caveat for folks tunneling X11 through ssh from low horsepower LCNC 
hosts. It entails encryption of the X11 traffic and my tests showed the 
compute burden is significant on my Beaglebone Black no matter the 
specific encryption algorithm 
(https://sites.google.com/site/manisbutareed/beaglebone-black-linuxcnc 
Sorry I haven't added the promised "details later" yet but it's taking 
me time to recover from a personal calamity). This was the work Dave 
Engvall alluded to.

For these systems I suggest a traditional redirection of the X11 traffic 
using the well-known DISPLAY environment variable (and typically a few 
adjustments on the X11-server host as well). It's terribly insecure so 
be sure the client and server are behind a worthy firewall.

Regards,
Kent

Any I/O pins that are not already used by something else.  The PRU code
is capable of driving any pin in the 4 32-bit banks of GPIO, as well as
the 16 directly-connected low-latency PRU output pins.

To calculate a pin number to use for the GPIO banks:

Pin# = ((gpio_bank + 1) * 32) + pin_number

...this is the same as the kernel pin numbering scheme, except one is
added to the GPIO bank so that zero results in an invalid pin number and
means "don't drive any pin".  This is to keep things safe since all pin
numbers default to zero the way HAL shared memory gets initialized, you
have to explicitly set a pin number before the PRU actually tries to
twiddle something.

If the SPI pins are free you can probably use it pretty easily with the
BeagleBone.  If you want to talk to it via real-time HAL you'll have to
write a low-level SPI driver to talk directly to the hardware, but
that's probably not necessary.

I use the on-board ADC for my thermistors, and have a python script that
uses the Linux kernel driver for the ADC to grab the value and then
convert it into a temperature that is injected into HAL.  It's not real
fast or hard-real-time, but that doesn't matter much for a temperature
control.

There are kernel drivers available for SPI as well, but I haven't tried
to use them.  IIRC the guy making the Replicape uses the Linux SPI
drivers, so there's probably something on his blog about getting it
working to get you started...yep, here you go:

[Emc-users] Thermocouple to LinuxCNC

2013-08-09 Thread Andrew
Hello,

I recently got a 3D printing head with K type thermocouple off ebay.
There are two kinds of converters for these thermocouples:
- AD595 with analog output 10mV/C,
 - MAX 31855 with SPI output
http://datasheets.maximintegrated.com/en/ds/MAX31855.pdf
The first type needs ADC (which I already have in 7i73 as the last resort,
but I would not like to use it for 3D printer).
Thus the SPI type looks preferable. But is it compatible with MESA sserial?
Or (even better) with Beaglebone?

Hello,

I'm trying to set up BeagleBone using Charles' image (with HDMI display).
As I do not have any cape board I simply connect A4988 drivers to BBB's
output pins.
K9.HDMI config has 4 stepgens, but I'd like to have 6 or 7. It loads with
num_stepgens=6 but the question is which output pins can I use for two or
three extra stepgens?

Is the LinuxCNC system a BeagleBone?

If so, I occasionally get a real-time error message if the Xenomai
thread latency ever goes over 25 uS.  Since the typical latency is
around 20 uS and worst-case latency is around 60 uS or so, this can
definitely happen.

I haven't (yet) tracked down why LinuxCNC seems to consider 25 uS a
"magic number" and throw an error, but if everything else is working
well the error is safe to ignore.  Also, IIRC the latency should have
been reported in the error message.  If it was 25.xx, you're seeing the
same issue I'm referring to here.

Only the 8i20 and possibly the 7I77 if its sserial remote firmware is older 
than R14 need updating

OK I will fix these

The host FPGA firmware sserial version is printed in the kernel log
(read with dmesg)

Yes you need host sserial version >33 to allow setsserial to set the
baud rate (needed to access the remote in setup mode)

sc9054 should run on XP32 (it does here) but you will need to boot win7 64 in 
development mode to run sc9054. However, sc9054 will not help with updating 
the remote sserial firmware. If you want to update the 8I20 firmware via 
windows I would use a usb-serial adapter and the uflbp utility.

I do think its easier to do this via linuxcnc however (no funny serial 
cables so update in place with your existing setup)

You can do this either by connecting the 8I20s to the 7I77s sserial expansion 
port (the 5I25 will very likely have sserial firmware > R33 and if not you 
can update it via mesaflash), or installing updated rmsvss6_8 firmware for the 
5I23. I can make a up to date version of this today

Re: [Emc-users] MESA 8i20 and enable signal

Dear Peter,

continuing the topic, could you please help me to update firmware (in 
case they need one) of the boards I have:
3x 5i23
6x 8i20
1x 7i49
1x 5i25
1x 7i77
1x 7i37
a lot of 7i39-HV

I can give you remote access to my PCs. What tools do you prefer? I can 
run TeamViewer for example..

What I am working now on and met a problem is a setup of 5i23, 7i44, 
7i49, 7i37 and 6x 8i20.

This is what I started to write you as I went through 8i20 update way:

To help make your README and update tools better:
Change sudo ./installss to sudo ./ssinstall
You can put a note about path and making ssinstall executable
Change /bin to /lib inside ssinstall
Write where to find host FPGA firmware sserial version (I don't know)
You could note / put a link to info what is master version of LinuxCNC
Note about executable for update* files
Note that user has to specify path to firmware file or copy it or script 
to one dir. Or change the script to take firmware from default location.

And then I stopped at:
[ 7317.595333] hm2: loading Mesa HostMot2 driver version 0.15
[ 7317.599591] hm2_pci: loading Mesa AnyIO HostMot2 driver version 0.7
[ 7317.599653] hm2_pci :01:06.0: PCI INT A -> GSI 20 (level, low) ->

[ 7317.858887] Version must be > v33 and you have version 
31.hm2/hm2_5i23.0: failed to parse Module Descriptor 4


I tried to run SC9054W.exe for 5i23. Drivers do not install on Win7 64. 
And SC9054W.exe does not run on WinXP 32. And I don't know where to get 
new sserial firmware files.

To get a pin to show on the map for your location you need to enter your
