SWPLinux: I just remembered - capacitors
what other stuff did I say I would bring (that I didn't already have in the truck?)
dude... you didnt???
I was talking to SWPLinux
someone wanna write up emc2 for Linux Journal?
[03:53:13] <seb_kuzminsky> http://www.linuxjournal.com/content/call-articles-cool-projects
SWPLinux: Well you must be on the road =)
yep - Cleveland
SWPLinux: I picked up a Lenovo S10 for $399 out the door... not a bad lil machien actually
is that the one you pointed out today or yesterday?
what exactly is "WSVGA"? is that 960x600"
- that last "
probably, wasn't SVGA 800x600?
yeah, that's why I figured 960x600
just never seen one like that before
I did see an interesting high res monitor at Costco though - 23", 2048x1152
$399 I think
maybe $299, not sure
I've been droolling somewhat at LCDs
microcenter has an ACER, 25", 1920 x 1200, for $379
the next month or two will be the sweet spot pricewise, I think
that's about the going rate
maybe less if you get a sale
the new video connectors confuse me
there is the good old 15 pin d-shell, then DVI, then something called HDMI, which I think is more TV than monitor
hdmi is for copy protected video
a lot of monitors have HDMI, and it will eventually be useful if you want to watch HD video on it
eric_u: no, that's HDCP, which HDMI display devices all have
my current TV (which I rarely watch) is a 19" analog, which will soon become somewhat of a paperweight unless I buy a converter box
some video cards and even motherboards have HDMI connectors
I have a DVD player (analog out), but I wonder if I shouldn't just get a dvd reader for my PC, get a nice monitor, and call that my TV
my monitor doesn't have dvi, just hdmi
HDMI is faster DVI - a single link of HDMI (don't remember whether that's 1.0, 1.1, 1.2, or 1.3) has at least the bandwidth of dual-link DVI
and the connector is smaller, so the next laptop you get will probably have HDMI instead of DVI or HD-15 VGA
plus no D/A - DVI often has analog output in it also
pretty sure that Acer monitor says D15 and HDMI
so D15 with existing video card and kvm switch, HDMI with the next one
that's what mine has
best buy didn't have a dvi to hdmi conversion cable, I was not pleased with their technical competence
you can adapt DVI to HDMI
and vice versa
I know that, but I needed a signed note from my mom to convince the best buy "experts"
there can be issues with protected content going through DVI, though it's supposed to work
SWPLinux: 1024 x 600
HDMI has DRM built into it, DVI is sorta-kinda suppose to too, but not so much
Dell E6400 has Dual DVI (docking station) + HDMI (built in)
Dual DVI as in two DVI connectors
HDMI doesn't necessarily have the DRM built in. that's what HDCP is
all display devices with HDMI should also have HDCP
not all devices that have HDMI output support HDCP
seems like some early ones didn't
HDCP = "High Definition Content Protection" I think
yeah, and some motherboards and video cards say "HDCP-ready", because you have to have ann OS that uses TPM or some such drivel
on that note, good night
i'm in search of some help with my newly installed limit switch
installed and ran stepconf to let it be "Maximum + home" limit type, but now in EMC2 using Axis, it will not power on and says it has a 'joint 0 on limit' error
there is a small check box that allows to override limits, and if i check it then it will master up, but it will not home and faults out with the same error
i did attempt to set the switch type to only "x home" to try to avoid the limit problem, but it did not seem to help.
it thinks you are on the limit switch
yeah but why
maybe you need to invert the signal
i tried that
halmeter shows my limit to be functioning properly
the little digital readout also updates properly when the limit is depressed, showing the small arrow like icon
if halmeter shows the (say) axis.0.neg-limit-switch-in is FALSE, you will be able to turn the machine on
i will run and check that signal
so when the little arrow isn't there, it should let you turn the machine on
yes, but it does not let me turn it on then
if the arrow works right, the signal is right
can you check again? if the arrow is not there, machine should come on
when i press in the limit switch manually, i get a checkbox enabled for override limits (which makes sense)
okay i will check again
the arrow is not there, but it will not power up and gives the "joint 0 on limit" error
i checked the axis0.neg-limit-in and it is FALSE
as well as the axis0.home-switch-in
position is just a random position, wherever I left it last time i used it i guess
am i somehow hitting soft limits? I thought those didn't take effect until the machine was homed
that is true
"on limit" does mean it thinks a limit switch is TRUE
did you check both neg-limit and pos-limit?
curiously it says "joint" instead of "axis"
would that mean anything to you?
that is correct
i will check pos-limit, brb
joint 0 is "X"
all three signals are false on halmeter, and become false when i depress the limit switch
oops they become true i mean
all are false, but when I push the limit switch they all become true
so you hooked this one input to both limits and also home?
there is only one limit switch
ok I see
it functions for the operator side limit and also the home position
when you try to turn the machine on does it give an error right away?
first I have to clear the e-stop which it does fine, but when I hit the power button icon on the Axis toolbar, it errors out
can you put your ini and hal files on http;//pastebin.ca
sure it will take a minute though, that machine is not networked
I don't understand this behavior - something must be funny
that's ok, I'll wait
yeah i was wondering if i somehow screwed up the upper and lower limits
did you change those too?
for the x axis, you have to enter them into stepconf
i tried a couple of different ones
is MIN_LIMIT less than MAX_LIMIT?
perhaps not, i will check
I'm not sure how to check that actually
i changed the values in stepconf and it still does the same thing
what are the min and max limits?
I will just copy the ini and hal files over to this PC, that might be the easiest
-75 and +75
are the min and max
with home set at +75
ok, I don't think that explains the problem
I would still like to see the files
okay brb, gotta find a usb stick
[05:39:18] <dareposte> http://pastebin.ca/1290051
that's the hal file
[05:40:36] <dareposte> http://pastebin.ca/1290053
there's the INI file
and looking at the INI file I think I see what you were talking about with MIN limit and MAX
MIN_LIMIT = 74.999
MAX_LIMIT = 75.001
yeah it can only move .001 mm??
I wonder if I should omit the negative sign then
what's your travel on X?
it was autogen by stepconf
travel is about 200mm
i had it configured for +/-75mm from axis centerline though
well that is what was attempted
seems like you missed a - sign
what version of emc is this?
2.3 i think
it was pre-head at the time
so a recent trunk cvs checkout?
or is it old?
it was new as of about a month ago
fresh from cvs
stepconf has had a LOT of bugfixes in the last 6 months
it was my error interpreting the values it wanted, i fixed it now but still no dice
you probably ought to update your cvs, but I don't think that's the problem right now
the new HAL ini file shows the correct MIN=-75 and MAX=75
still get the same error though
but it seems to take a bit more time now
about 1/2 second before the error pops up
if i'm quick I can hit the home axis button and it will start to home, then fault out with the same old error
I will copy the new files
ok this is different now
I think you have noise on that signal and it's seeing very short activations of the limit switch
you could set up halscope to trigger on a rising edge of that signal
I bet you will see something
how is the limit switch wired?
it's a direct wire from the common to the input
i would buy the noise problem, it runs near the VFD wires
so one side of the switch goes to ground and the other to the parport input?
which is probably a bad idea
well through a breakout board of sorts
I bet you need a pullup to +5 on the parport input
its all buffered IO
check with halscope to be sure that's the problem, then you can be sure you're working on the right thing
okay I will attempt to do that
which signal would you recommend checking?
the signal is called max-home-x
[05:52:31] <dareposte> http://pastebin.ca/1290056
there's the new HAL file in case that might be the problem still
and the INI file: http://pastebin.ca/1290057
good, much better limits
yeah it looks like there is some noise on the lines
i tried re-routing and even e-stopping the vfd, but no luck
not really, it took almost an hour to figure that out :-)
I bet you need pullups
i think there were multiple issues
yes that always makes it harder
well the noise occurs when the limit switch is not made, i.e. at 0v
when the limit switch is made, the board is getting +5v applied to it, and the signal looks nice with no noise
so maybe the problem is ground noise coupling or something
stabbing in the dark here
so you saw halscope trigger on the noise?
the noise was full scale
about 1-2 peaks per second
i guess the best thing to do is pull out the real scope and see if I can find the problem
and the best thing I can do is go to bed!
thank you for your help!
enjoy your slumber, I will be firing up the old HP
you are on the right track - good luck and report back!
dareposte: cradek said "I bet you need pullups", but you said "well the noise occurs when the limit switch is not made, i.e. at 0v" and "when the limit switch is made, the board is getting +5v applied to it, and the signal looks nice with no noise". So maybe you really need pulldowns? Are there any now?
If you had a 1K or a 470 to throw on just for testing, the results would be interesting
dareposte: If your board/interface already has pullups available, you could jumper one in and then reverse the sense of your switch to active low both in wiring and in the hal/ini files, if that's easier for you.
The board i am using already had a 1K pullup resistor
it was wired from Common (5v), through the NO limit switch, and back to the input. The input was normally pulled to ground by a 1k pull down resistor
adding another 1k pull down resistor straight to ground reduced the noise level such that the machine could power up and home its x axis, but starting the VFD immediatlely would cause the same error
If I switched to active low, it might be a more effective way to do it, since it would have the full 5V power supply to overcome the noise. The problem then would be perhaps losing home position while on the limit switch due to noise, but that would be easier to deal with I think
the other option might be to add some noise shunt capacitors from signal ground to power ground
I wouldn't think a .005 would hurt there, since the signal is coming from a mechanical switch anyway. You could try a .1, but there might be issues. I guess we'll see?
Just so I understand, when the switch is closed, the input signal is 2.5V? (1K pullup, 1K pulldown?)
sorry I must have explained it poorly
the "common" rail is +5v, unbuffered straight from the power supply
the input is a 74HC series logic chip, pulled to 0v by a pull down resistor
the factory board had a 1k pull-down resistor, and I added an additional 1k pull down resistor in parallel
so it is effectively a 500 ohm pull down now, which did help enough to power the machine on
turning on the spindle motor overwhelms the pull down and gives the error, so it seems to be fairly certain that the noise is coming from the VFD
I'm thinking that changing the limit from a NO to a NC might solve it, the soldering iron is heating as I type
And there's another 1K in series from +5 through the switch?
nothing in series through the switch
changing to an NC won't solve the underlying problem of poor signal shielding, but it would at least cover it up some
it's just put together with hookup wire, run in the same area as the VFD motor wire, with no shielding. Not that surprising that I'm having problems now that I think about it.
5v signals don't really give lots of room for noise on the lines anyway as compared to 24v signals
OK, worth a try, we'll see. On the other hand, a 250 ohm pulldown (4 1Ks) is only 20ma at 5V, not unreasonable at all for a non-gold-plated switch.
Yes, I may be about to experience some of this for myself, as I help a friend convert one of his mills to EMC2
I have a live CD question if there is anyone around that might be able to help
I hope to use one Opto board and one Mesa board. We'll see if I have any problem like yours.
Hi Benjamin_Mullin , don't know if I can help, but what's your question?
I've tried using it on two separate machines to try and get a feel for EMC (realistically at least a few weeks away from really wanting to use it)
The first machine only appeared to have a resolution of 640x480 available. The documentation indicates that if it is in 800x600 the vid card is likely unrecognized... if its worse than 800x600 is that the same issue?
The second machine, which is a PII 450 (so getting fairly old), just stalled at installing hardware drivers. Any thoughts?
sounds like pulldowns needed. look at the signal in the untriggered state before any mods. if it's floating, or easiliy influenced by your bod, then try pulll downs.
or make sure the untriggered state is really connected to 0V of the sensor/switch supply
KimK_: switching it to a NC switch relieved the problem, but the noise is still there on the ground line. Now if the machine is on the limit it will sporadically fault out, but it runs fine once it's homed and stays off the limits.
tom1: the untriggered state is connected directly to the 5v rail now, with the triggered state letting the input float. The input "floats" at 0v via a 500 ohm pull down
On the bright side, the cheapo Omron limit switch I'm using appears to be repeating to about a half thou
much better than anticipated for a "simulated roller" enco special
Benjamin_Mullin: I had lots of trouble on the 8.04 release, and even on the 8.10 (so, not an EMC2 problem), with unrecognized video resolution, 640x480, even 320x240, etc.
Ben: There are guys on here who can help you, but I don't think any are on at the moment
I tried lots of things, finally had to put in an empty X.conf file, then it seemed happy.
oh KimK's back, didn't see you on here
Thanks for your help KimK and tom1, i'm hitting the sack
Sorry, didn't mean to be gone so long.
OK, goodnight. Let me know later how it went. Thanks.
I was trying the 6.06 "Dapper Drake" version.
good luck on your upcoming install, I'm very interested in a MESA board myself
Thanks, I'll let you know (eventually). Might fool with it on the table over the Christmas break.
Benjamin_Mullin: 6.06? Oh, OK. Not sure then. Are you using an Nvidia card?
Actually I'm not sure. The old machine which didn't even finish loading is an old Gateway machine so its probably a built in video. The other I'm not sure.
Have you tried Ubuntu 8.04 (with or without EMC2) or 8.10 on the older machine to see if it changes a no-start to a start?
Or anything really, it would be nice to know if any recent distro would run on your P2 450.
Just for information's sake
Sometimes there are start options you can invoke which might help, like noapci, framebuffer, etc., maybe check the start menu for help or options? Worth trying, anyway.
I have not. I'll try 8.04 in the near future.
The P2 is the preferred computer anyhow as it is the one in the shop
I seem to recall that EMC2 ran OK on a friend's P2 750(?) Maybe a little slow on the menus, etc, but OK if not in a big hurry.
I have it running on a P3 of about that speed
I could make sure and go back and check with him on that if you wish.
Well, there you go! Thanks, eric_u
good to know
eric_u: What's your machine interface?
that is important, I'm using a Mesa 5i20
oh no! for the first time in my life, staring at the word "Linux" brought the sound of LIN-NICKS to my head!
if you are trying to do step/dir generation, that might not be enough machine
eric_u: What have you got attached to the 5i20? I'd guess a 7i33 quad servo, and, what, a pair of 7i37 16-in/8-outs?
almost, only on &i37
Any DC I/O on the other two 5i20 connectors?
didn't really see the need for it
OK. Keyboard/Mouse/F1/F2 E-stop?
big red switch/ external electronics mostly
this is a big servo driven mill
not really running yet
Thanks, I was about to ask what kind of machine it was
How big is big?
bridgeport series II
not as big as some
Hey, nice, I'll have to put you in touch with a friend of mine, also doing a Series II
mine was gutted
Hey, whatever gets it in your hands, right? You said servo driven, was that factory? I thought they were all big steppers?
steppers were removed
as part of the gutting
Well, good choice then, going to servos should make an even better machine out of it. Have you run them on the bench with EMC2?
not yet, got the encoders to work
gotta get back on it, last year was a monster at work
What do you do?
engineer doing research
OK. And your new servos had encoders already, I imagine?
yes, I used the encoder output from the drives
Oh, nice! I like it when drives do that. Solves a lot of problems. Sometimes the motors have resolvers, and even that's OK, then.
these will even take input from an encoder to drive them manually
thought about doing that
It gets better. What make are they? How big are the motors/drives?
2 horse, thereabouts
Did you have to make an adapter, or did they just drop in where the big steppers came out?
had to machine adapters
I had one motor that fit, but then I removed it
I don't remember, is the Series II belt or rigid coupled to the ballscrews?
timing belts, you can ask the finger on my left hand that I managed to run through them about this time last year
Ouch. Did your finger recover?
yeah, it feels a little strange, but no major damage
You're a lucky feller.
Ha, that works too
yeah, I learned something about brushless motors I didn't really know
If your finger count still equals 10, that's a good thing. What did you learn?
they aren't really as closed loop as you might think
Why, what happened?
there was some problem with my feedback cable
I was just testing to see if the motor was servoing, and gave the belt a tug
that got the motor into sequence and it took off
Ah, and you had some kind of mixup in the U/V/W Hall effect feedback or something?
bad connection I think
OK. But in any case, it took off spinning unexpectedly. Well, "May Start at Any Time", I guess?
in my now expanded experience, they usually don't start up without some help if something is wrong
What city are you in? (wondering how far from Minneapolis, where my friend's machine is)
I'm in central Pennsylvania
Well, that's a long trip. Virtual travel, then.
yeah, it's too far
did that drive one time, it was a lot further than I thought
I'll introduce you if I ever see you both on here
there are quite a few BP series II owners around
Minneapolis? Are you in MN too KimK_, or just your friend with the BP?
Yes, so I am told. Maybe because of the old controls and old (trouble-prone?) stepper drives? Well, like I said, whatever gets them into our hands at a bargain price, right?
yeah, the old control has made quite a career for some people
and there are some nice ones around that were hardly ever used
Benjamin_Mullin: No, I'm in Omaha. My friend with the Series II is in Minneapolis. You're in Minneapolis, then?
I live in an outer suburb, but work right between Minneapolis and St. Paul
Do you have a machine in mind for EMC2?
I'm working on a tiny little mill based on some linear actuators I got from some scrap at work
about 5"x5" travel
[08:41:19] <Benjamin_Mullin> http://www.flickr.com/photos/26107619@N07/3105878092/
That should be interesting. Planning three-axis, or more?
starting with two, planning on three, then we'll see
What will you use for a spindle?
I'm on dialup, I'm still waiting for your pix. I'll go look again.
OK, pix is in.
I'm thinking of starting with a rotary tool and we'll see where we go from there
OK. People who should know tell me that common tools like Dremels, routers, and even die grinders have too much runout for fine work. (Engraving? PCB milling? What?) FWIW. I've never tried to measure runout on one of these. Anyway, you might want a plan B just in case, since your work envelope is small.
I have heard similar. At the moment I am keeping the cost of entry minimal. I want to see something working first and proceed from there
It's way past time to be in bed for me though. Thanks for the assistance. I'll probably be around more in the coming days/weeks.
Yes, that's a point too. Besides, you may find that you have a lot of unwanted play in the actuators, etc, that might be hard to remedy. In that case, maybe a Dremel is good enough?
Oops, too slow
eric_u: It's probably late enough for me too. Thanks for jumping in.
been so long
last time ive here, some one has problem with rail-metal-crack
..i have the result for that
..if not too late
ok, made 3 drill hole, on the side of cracked-metal, and manage to patch a 3-BOLT_strong_steel on them
these 3 Bolt would prevent the rail-metal to tear apart when the heavy load being put on the edge of the crack
then with the hair crack, u should give it a glue... these glue prevent water to go in there and develop Nasty RUST in there
Nasty-Rust would make the crack WIDER, just like a Tree-Root on the floor...
3 drill hole would shape like a triangle.... mustly like a LINE
like this . ' . okey this is triagle
or ' . '
if u grinding the Bolt heat, it would as good as new again

the problem with emc is the expectation that it comes with free linux support
ubuntu support is pretty good
and there's even professional (as in paid) support for it
the thing that a lot of folks don't think about is Mach only has 1 developer
I've always figured Mach would die as soon as Art quit. But then he quit and it's still going
but I'm not sure if it can keep things up, bill gates could kill it tomorrow with an update

well, for starters, "emc" is one char shorter than "mach", so it can be transmitte 75% faster

one thing that I feel is lacking with emc is a good set of default cycles :)

or you could just do the ramping yourself and just call up the cycle withput any plunge.

dmess: either way pocketing a 10" hole with a 10mm endmill takes quite a bit of time to write in g-code
I suppose I should upgrade my ubuntu version

that looks like a 'real' machine
dmess: how many lines of g-code do you think it would take?
it's just a batch of sheet metal around a bench mill
DanielFalck: one of the many 'real' users ;)
It's not a real machine until there is a cab for the operator
whats the tool change time on that chip to chip??
stuart has some 'real' machines
dmess: not mine
that's a fact
that machine needs a green background
oh i see...
and fullscreen emc :)
yeah, but it's cooler to notice ubuntu on the operator's screen
maybe there should be a category in the wiki for 'manly man machines that don't run steppers ' :)
that machine can chip to chip t/c in under 5 seconds
i had 3 DZ 16's at 1 place i played at
an mpg would be nice
if I ever build a machine I'll make the control housing round on top.
it's a too great place to stick tools on otherwise ;)
they had 2 spindles and the same t/c system no just buttons
then you'd hate yourself
make it angled
maybe I should just make a tool shelve on the side of the control for tool holders
I've resolved to start keeping my tools in the toolbox
they really nailed it for the robots I work with.. the cabinet is ~2.3m high
so no chance to put things on top
oh.. I mean collet chucks..
that works too
actually 2.5 meter tall cabinets would reduce the frustration that rounded top cabinets would cause
I'm going to make something where I can stick tooling into..
im one of the poor guys without a toolchanger
i had a 6 " face mill snap the bolt and danc over the fixture towards me and into the chip bin on those machines once
well.. off to bed for me, another drive tomorrow
good night all
there seems to be a circuit board on top of that thing
and a clear plastic mouse
anon.. winerack type tool changer
I need to throw up cash for a spindle encoder and a vfd first
or a vfd and some time to hack togther a macro to position the spindle..
no retainer knob drawbar on my machine either..
i got the c6 board from pc4cnc
and a 7.5kw vfd is not cheap :/
mine is 5.5
well that should help
they are still a bit over 1000$
i got my single for gatuaties
i.e., it's stolen
eric_u1: for $1000 ?
no, for gratuities
no... just old surplus and out the back by the owner
she's a doll ... dont have a clue wht her company does
wonder if my boss would give me the fatigue machine we aren't using
and she likes it that way... go figure
dmess: well it makes profit isnt that nice?
do you really need to know more :p
what sorta fatigue m/c? k1c'S
it was custom built for NASA
by a company that is now MTS
it was used on the Saturn V project for high temp fatigue/creep tests
WOW there would be some awsome sensor and load cells on that...
no, just a frame
all that stuff is obsolete anyway
I have the load cells somewhere
its a museum piece in 1 chunk
the last experiment they used it for lasted one month for a single load cycle
our landing gear in 300M material fail a K1C test in just over an hour in aermet 100 they run overnight and go 23 - 30 hrs
and thats why the navy wants our nose gear for the f18 e/f/g

I wonder which 'real thing' he refers to?
he thinks cnc machines shouls act like windows programs probably..
mach user interface is very clear?
he's not exactly the sharpest knife in the drawer
I suspect that most people find it simpler
my emc machine is not having network problems - joy
Hi, does anyone have knowledge or experience compiling emc2?
I'm rusty on the subject
do you want to compile cvs?
Hi Eric, getting a compile/linker error in the hal.so library of duplicate symbols
no, downloaded source from a tarball
that's a tough one
looking at purchase of a CNC mill for the company but wanted to try the software first
install from liveCD, anything else is madness :)
maybe I should say, will soon lead to madness
was there a special reason to build from a tarball?
with the liveCD, you can play with the software and not even install to the hard drive
did that at work, drove steppers around and everything, no install
not really, looking at the Sherline CNC mill and trying to save about 1K
if you have a reasonably fast Internet connection, the liveCD is the way to go then
plus have a few spare machines with most of the support software in place, but I like your suggestion. Do you have a URL/source for an iso image?
linuxcnc.org look up at the left hand corner
does that CD require any real-time stuff such as RTAI installed prior to use?
the live cd is pretty bullet proof my 15 yr old son has done it a few times
its ALL there
no, it runs rtlinux standard
one of the best ways to get an RTAI install without tears
sounds like a plan, has anyone run it with the Sherline CNC mills?
i agree.. i remember trying to POUND emc on a redhat system way back when... worked for monts and it never did work CORRECTLY... then the live cd caught up to me
I thought there was a config in there for the sherline, but I could be wrong
i think its there...
the config wizard has a sherline config
castle: start with the short getting started guide
[23:45:09] <BigJohnT> http://www.linuxcnc.org/docs/EMC2_Getting_Started.pdf
thanks for info, our company does flight sim stuff (www.lfstech.com) and we've been getting a lot of inquires for hardware thingies and looks like 2009 we'll add some support in that area
even if your on dial up there are instructions in the getting started guide to download the live cd
I would not get a hobby mill for production work...
cool stuff your working on
most of it is small panels, medium sized parts, knobs, gears, etc, it look like the Sherline would be a good starting point. Comments?
looks like you need it to do alot a work???
a sherline is not a bridgeport...
we hope so
you might be under buying the machine
my machinist has a bridgeport, unfortunately it is an older setup, with no CNC capability
it till you do it
it would be better to retro the B/P than invest in a sherline... its JUST a better machine and spindle
and all $$ can go to the retro bcz you already own the machine
I never liked the idea of a BP retro on a working manual machine
if you want to make and sell stuff you need a machine that can make it fast enough and easily enough
and even if you dont make a profit making something on a better machine is less frustrating
throw ball screws in... i had a quote for precision ground 100$ / meter
that's a good deal
that's why old BP cnc is a good idea, nice ballscrews
come on/... lets grab a brain and think
my expertise is software and flying, sounds like I need to do a bit more research
well in hard machines and some flying...
a BP or similar size knee mill is actually the perfect size for instruments
what do you fly?
