hi Paul, is it morning there already? 8-)
Has been for over two hours
yeah... 2am in the morning
seems my days and nights have been inverted lately, been too busy
steve_stallings : Just be lucky you don't live in Alaska
I would be fine for half the year...
24 hours of darkness, followed by 24 hours of sunlight
Actually, I think it's 3 months of each iirc.
Time for bed...
Does anyone care that I found bugs in BDI in respect to disk partitioning during install?
\o/ BDI-4.23 installing to SCSI....
Jymmm: You have something to say ??
Yeah, SCSI sucks.... too expensive in comparision. (less a stroage array where the performance is needed)
* paul_c has four 9.1Gig SCSI drives plus controllers kicking around. Total investment....
my scsi drives lasted like 7 years before dying, where teh ATA133 drives lasted about � a year..
anonimasu dont buy WD/Maxtor drives then
and SATA drives are mapped like SCSI drives in a Linux system...
so hopefully, they should work too.
everything is mapped like scsi drives in linux
well... The kit was free.... So I may as well use it - Even if it is only for testing purposes.
free is good
The current test system: http://www.kontron-emea.com/downloads/datasheet/VIPer830.pdf
paul_c: Is there a way to net install BDI? Like boot from a lfoppy to another machine?
The BDI-2 and BDI-4 both use anaconda.... So a net install is possible (in theory).
paul_c: you have any idea on what I need to create a boot floppy for the install?
um.. A boot floppy is the one thing missing from BDI-4
If you feel masochist, you could use a Debian boot floppy.
I only know debian install, not remote install like from another local machien.
[16:44:12] <paul_c> http://www.debian.org/releases/stable/i386/index.html.en
has some info on floppy/net installs
Thanks, but way too time consuming for just a "maybe".
damit... dhcp3 is causing "problems"...
Jymmm: Did you have a partitioning "bug" to report ?
paul_c: When I tried installing in the Laptop bug of box popped up saying 'bug' in blah.c: 5xx
I didn't get a succesful install (I think due to the cdrom)
but I just think it didn't like the hdd for some reason.
4.21 never made out in to the world...
The last public release was 4.20
Can you remeber at what point the error popped up ?
before and about the auto partion point.
sounds like a libparted bug - Unfortunately, beyond my control.
If you come across it again, note the message in full and there might be a chance of a workround in anaconda.
ahpoo... Sherline's configs use the wrong GUI
bloody hell.... SCSI does impact on performance !!!!
first install on a SCSI box... Runs the Sherline GUI fine... But...
Switch between views on backplot, and the whole thing stops while the screen gets redrawn.
Now.... That was... um interesting - Axis bombed out & killed KDE
* Jymmm would like to note.... Don't buy a machine from K2CNC
Does anyone know a good way to measure backlash?
How close do you want to get ?
I'd like to see how much (in any) backlash there is.
to the nearest 0.000001" ?
Can I do that?
4 digits would be nice
with an inferometer & temperature controlled lab, maybe.
You need one of these > http://catalog.starrett.com/catalog/catalog/groupm.asp?GrpTab=More&GroupID=462
preferably a "tenths" gauge
I have a (cheap) dial gauge, but I'm not sure how you actually TEST for backlash.
OK... Mount the dial gauge in the spindle...
move the table in the + direction (say 1")
Place a solid block on the table and carefully slide it up behind the dial gauge lever until you get a reading
Note the reading....
Move the table another 1" in the + direction
Now move the table back in the - direction exactly 1"
the dial gauge should now be touching the block again - Note the reading for the second time.
The difference between the readings is your backlash
difference direct or by half?
Total backlash at the point it was measured.
Backlash can vary along the length of travel.
1.00 - 0.90 = .10 <--- .10 or half that value?
Kinda nice, but not available in the US --> http://www.jlindustrial.com/catalog/product.jsp?origin=SEARCH%3AKEYWORD&id=AFE-10020L
info here --> http://www.welsoft.co.uk/machmill/hs290.htm
Normally, one enters the full backlash reading and let the software decide when & where it needs half.
Ok, that's what I was wondering. =) thanks

Bastard keeps talking about the 'optio-set', but can't get the damn ting here! LOL
Renishaw do something similar
I wish I could figure out a way to 'optically' measure distance then be able to feed it back into the controller.
like during manual tool changes, etc.
but that would require physical contact, wouldn't it?
yup - Or are you thinking of something to measure tool diameter & length ?
to (re)zero out Z axis

[18:00:43] <paul_c> http://www.renishaw.com/client/product/UKEnglish/PRD-6106.shtml
should we contact them for samples to intergrate into EMC?
I dont think they care :D
if it means selling more product, they do.
Jymmm: They can afford to skip emc.
that stuff if way out of the range anyone that has to use emc can pay for..
atleast the laser toolsetter ;)
The principle is pretty simple - It could be used with emc
If one used a $0.99 laser pointer, what could be used to read it with?
Any photodiode would detect the beam
Get one designed for 660nm(is)
why that wavelength?
Near IR iirc
red goes from 630 to 700nm
depending on the doping materials
[18:15:09] <paul_c> http://www.marktechopto.com/engineering/history.cfm
gallium arsen something or another =)
635nm if I remeber correct
* paul_c -> dinner.
anonimasu hows your USC coming along?
Jymmm: oh, not much at all..
work and more work..
going to work all day tomorrow + sunday
so I doubt I'll get time over for the USC
i'm going to add optocouplers to parallel port, using an IC7805 for 5V ps
should i add some resistor between optocouples an parallel port pin ? anyone know ?
i'm also using pin 12-13-15 for limit switches
Jacky^: Resistors, Yes - Unless you use TTL level input optoisolators
paul_c: i've 2 types here
one is 4n33, but i will use it for limit switch only..
beacuse it have a slow raise time.. 100 us
the other is pc817 toshiba, should have 3 us
6N137 is rated at 10MBits/Sec
[19:39:43] <paul_c> http://www.fairchildsemi.com/ds/6N/6N137.pdf
I know.. i've some other link
the problem is to request an order just for 1 ic :\
when i've here a lot.. but 4n32-4n33 :(
the only i found to be fast should be the toshiba
i could use it for pin 2-7
and 4n33 for pin 12-13-15
aniway i will try ..
i'll also add the resistor then
otherwise, i could wait when i'm ready for a consistent order..
maybe the best way
ok, tnx, later..
Jacky^ is now known as Jacky^afk
You want HCPL-2730 or HPCL-2731
Not quite as fast as 6N139
Jacky^afk is now known as Jacky^
PhydBleep_ is now known as Phydbleep
Phydbleep Hey you old dawg!
is Phydbleep or is a bot ? O-o
