Arto's complaint here has nothing to do with path following - it is a display artifact only
AXIS draws the backplot very slightly "above" the preview lines so it "covers" them. In perspective, the viewer is not really "above" the preview anymore so it doesn't quite look perfect. It's harmless.
ok I didn't know that
if you need an exactly perfect preview-vs-backplot, you have to look at one of the orthographic views.
Is anyone driving to Fest from the East Coast?
luckily for me, I start substantially closer than that
steve stallings is in va, and I think he's coming to fest
that's the closest I know of
I just checked the price of airfare and am not a happy camper. If I had booked earlier it would be around $200. Now it's over $400.

lerman: other thing I know is that jmk is flying into kansas city and driving a car from there .. might be a better fare if somehow you could ride with him from kc
Thanks. Let me check those fares.
steves_logging is now known as steve_stallings
steve is flying out, riding back with Matt, and he go his ticket over a week ago
no, Steve is (probably) flying out Saturday, then flying back Wednesday
notice I said steve not Steve
oh, right ;)
oops, sorry for passing along misinformation
ok, how about some advice for a newbie... I am hoping learn enough at the Fest this year to get into light duty EMC development, like HAL setup, COMP builds, and run in place
... so what should I download onto my laptop while good bandwidth is available?
what do you have on your laptop so far?
apt-get build-dep emc2 and apt-get emc2-dev are all you really need
there's more if you want to compile modbus stuff (glib, should probably be part of build-dep at this point)
[15:36:44] <jepler> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#On_Ubuntu_with_EMC2_package_already_installed
and maybe more for documentation
Use apt-get to install additional packages required to rebuild emc2 from source:
sudo apt-get build-dep emc2
sudo apt-get install build-essential
SWPadnos: yes as far as I know it's in build dep
hmmm. ok. there seem to have been a rash of complaints lately
(if it's not, it's a bug since emc will FTBFS)
what about Python, lyx etc. covered by dependencies?
right - you recently made a change to the configure error regarding modbus
yes -- you will be astounded by the number of packages that the step "apt-get build-dep emc2" installs
python is installed by default
note that cvs is not installed automatically
I will try to get around to setting stuff up this weekend and probably ask for more assistance, like cvs install
sudo apt-get cvs
for a lot of packages, if you run a command you think should be there but isn't, the error message you get will tell you what package to install
hi Matt! where are you?
Ann Arbor in the office
trying to get a thing called Open Embedded up on my PC
to try to make software for the beagle board
hey steve! I want (I think) a usenet feed. Giganews? Newsguy? Any public servers that aren't slow as molasses?
ok, just wondering if you were on the road yet
14 hours from here - get to the hotel on the evening of the 20th - means leave Tues morn at the latest
I am due into Wichitaw airport 10PM Friday
trying to figure out how much stuff I want to UPS out there
flight #? I can go pick you up. It looks on the map like Stuart's shop is practically at the airport.
fight 687 from Atlanta
dang, I hate it when I read back and see my own typos
I would say don't go too heavy on the UPS stuff. I'm thinking a computer and some of your boards. Any maybe some hookup wire type stuff. And a mill. And a rework station and tooling for the mill. That's about it I guess!
and a mill?????
Not too big. Nothing bigger than a Bridgeport. Don't go overboard!
I was thinking just one box with a one axis stepper slide, some books, docking station for the laptop, a couple of my boards
Seriously, I'm hoping this meeting is more intellectual vs. material.
maybe it can go as luggage
Yep. Your list there looks about right. I didn't even bring a scope.
oh, scope, yea that would be good, I have an old Fluke scopemeter that sometimes works
I was actually thinking that the stepper on your "1001 Electronic Projects" board might be enough.
Although a small slideway would be nice too. I'm thinking that Chris & Jeff may bring their stuff as they are relatively close by.
I do plan to take the PMDX-112 test board, and it can drive the single axis slide, same one I had at last fest as part of the digitizing camera rig
That'll be just fine!
plan to rig some limit switches on it for testing
That's a really good idea too. Does it have an encoder on it? Handwheel or on the motor?
no, but I can bring an MPG
for that matter, the PMDX-112 has a simple MPG and supports the tiny servo motor with an encoder
we can try to make a HAL component to run the H bridge via parallel prot and control the servo
I think the 112 is probably enough to keep us busy!
Stuart also has one, so there should be two there
steve_stallings, I think the up/down mode of stepgen will do that directly
H-bridge control, that is
skunkworks is using it for his large drive I believe
neat, wonder if I can find a tiny slide to put the tiny servo motor on?
yay! my $0.12 LED replacement bulb works
(in an Allen Bradley 800M switch)
but it will void the warranty
steve_stallings: how about a floppy drive leadscrew
if they still have leadscrews...
steve_stallings, I think the warrantee was voided some time before it was thrown out and "recycled" :)
mshaver, if you can still find a floppy drive
I think the lead screw is just an extension of the stepper shaft
SWPadnos: I still have 8" drives around...
but on the good side, a floppy would already have a home switch
steve_stallings: I think you're right come to think of it.
the floppies I've seen just mash the head one direction for a while and then call it homed
that's the grinding noise they make when they start up
oh, I a thinking of much older ones....
now that you mention it, mashing is how my very expensive old photoplotter homed the focus axix
Actually, if HOME_BY_MASHING is other than zero, then that's the signed float distance in machine units that the axis is driven to home it.
that sounds like an - um- good idea
EMC: 03bigjohnt 07TRUNK * 10emc2/docs/src/hal/pyvcp.lyx: a few more markup fixes
actually, providing for this method of homing stepper might not be such a silly idea
It's applicable to some axis types. Although I was trying to play off of Chris' joke!
I have a flight to Fest arriving on Sunday and leaving on Thursday for $277. What hotel are people staying at? Is it within walking distance to Fest?
steve_stallings: look up 8381K27 at mcmaster carr and see if that slide is small enough
lerman: I don't think any are within easy walking distance
also I think it's a pedestrian-hostile area
Last time I googled, there was one that was a short walk, I thought.
oh, I could be wrong then.
the days inn where I've stayed a couple times was 2? 3? miles
That assumes google maps has the correct location.
I don't know where people are staying - several different places I think.
I think Matt has us booked for the Western Holiday that Stuart recommended
Google Maps shows a Hampton Inn 1.3 miles North of Stuart.
Sunflower Lodge No 86 is .8 miles East.
Western Holiday - $270 for 5/20 thru 5/27 - double occupancy
will google maps generate walking directions?
you could (mayyyybe) get some idea which is better for pedestrians
it does have a "walking" option
as well as public transportation
lerman: the McMaster item is just the slide rail, no screw etc., I will persue the floppy idea and also look around among my junk collection
EMC: 03bigjohnt 07v2_3_branch * 10emc2/docs/src/hal/pyvcp.lyx: add info on stand alone pyvcp panels and fix some markups
I think all the hotels are a mile or more from MPM
some several miles
SWPadnos: see above :-)
oops, my slide reply should have been directed to BigJohnT
lerman, what time do you arrive/leave?
what are you making?
oh - that's a day off for me on both ends. nevermind :)
Arrive: 1:15 PM on Sunday (May 24)
Leave: 7:15 AM on Thursday (May 28)
I can probably pick you up at the ariport on Sunday
or the airport, whichever is wasier ;)
How much does a car rental go for in Wichita?
hmmm. I don't remember
I think it was ~$30/day
oh, $22.60/day I guess
I think a call to the shop during any daytime hours would secure someone a quick ride from the airport...
yeah, it's only 10-15 minutes
unless it's lunchtime :)
EMC: 03jepler 07TRUNK * 10emc2/debian/ (configure control.in):
EMC: try to minimize doc-related build dependencies
EMC: (this probably breaks dapper, which is pre-texlive, but we've already given up
EMC: on it in TRUNK)
some of us have previously shared cell phone numbers - yell if you want mine
Avis is quoting base rates of 266 for the four days.
I'll skip the car.
(although I'll be relatively carless)
BigJohnT: just something to play with as an axis using a servo driven by software PWM into an H bridge, small is better
steve_stallings: mill a slot in a block, tap a 1/4-20 hole in a piece of square to ride in it?
SWP: Where are you staying?
got an old ink jet printer? you might find a nice linear rail in it :)
lots of prospects, too little time, the closer to complete the better, hence the floppy idea
true, even the simplest setup would take an entire evening to make (always does)
oh well, time to harvest the hay, got past the cut the grass stage weeks ago, nothing but rain here.....
