[00:01:03] <PetefromTn> Yeah things were starting to look up.....for awhile anyways. I am gonna just grab some cutoff wheels for my angle grinder and buy a sheet of steel and hit it tomorrow hard. Hopefully things will go well and I can shoot some epoxy paint on it and reinstall it over the weekend and be milling and testing by monday...
[00:02:12] <JT-Shop> you do know for steel you usually just use air with carbide tooling
[00:02:21] <JT-Shop> cool
[00:02:21] <JT-Shop> no fab shops near that can shear it to size?

[00:07:03] <JT-Shop> say goodnight Gracie
[00:07:07] <Tom_itx> is carbide tooling more effective for you than hss?
[00:07:15] <PetefromTn> Actually my friend had a nice shop with a full complement of sheetmetal machinery press brakes etc. but they went out of business recently...
[00:07:23] <MattyMatt> if you're getting so much experience making your tools then maybe you should make them to sell

[00:08:09] <Tom_itx> just curious what happens outside an aircraft town
[00:08:24] <MattyMatt> a cnc slantbed the size of a sherline, that'd sell I bet
[00:08:48] <MattyMatt> with a turret, live tooling, bar feeder, auto chuck etc.

[00:10:20] <JT-Shop> too expensive for cheap hobbiest types
[00:10:25] <MattyMatt> I loved that pic of blddk's insert holders with built in coolant spray. they are as good an argument as any for carbide
[00:10:33] <MattyMatt> $250 per tho

[00:11:43] <PetefromTn> nothing there...
[00:11:44] <MattyMatt> bah deleted pic
[00:12:19] <MattyMatt> 2 jets of coolant in the insert holder, that converged right at the tip
[00:12:30] <MattyMatt> right in the chipbreakers
[00:13:15] <PetefromTn> Honestly I do not understand the reasoning behind any machine the size of a sherline. Hell if I wanted a HOBBY machine I would want it to be at least the size of like a 9x20 or 11x26 or something.... at least it could make something useful for more than jewelry or RC cars...
[00:13:53] <MattyMatt> some people just want small stuff, and only have a bedroom etc to work in

[00:50:08] <Tom_itx> doubt that would fit my space
[00:50:50] <Tom_itx> gawd those tool holders are huge
[00:58:58] <PetefromTn> Tom_itx: I dunno really as a hobbyist things are much different. I will say this tho, I have owned everything from a 3 in 1 machine to an RF45 to a knee mill and now a VMC and having done two retrofits now I can honestly say that despite my recent issues with rusty coolant troughs it has been MUCH easier to retrofit a machine that was born a CNC machine than one that was born a manual machine. If I was looking to get into a
[00:58:58] <PetefromTn> hobby machine I would probably look to find a good condition used CNC like a boxford or a denford or something that is already a cnc and then upgrade the control and motors to newer stuff. No machining ballscrews, no fabricating mounts, no trying to reinvent the wheel. Some of these small machines even came equipped with toolchangers and stuff like that. They are also well made. My RF45 mill was really sweet and I made all
[00:58:58] <PetefromTn> sorts of stuff with it both before and after CNC but it took a full year to do the retrofit and it was A TON of work..
[00:59:46] <Tom_itx> i used to work in a large shop and now i play with a sherline
[01:00:05] <Tom_itx> so i've been on the extreme ends of it
[01:00:21] <PetefromTn> If you have some more space to work with a CNC bedmill would be sweet to retrofit and very capable...
[01:00:54] <Tom_itx> if i got something bigger it would need to be some sort of tabletop or prototype cnc
[01:01:05] <Tom_itx> i agree the sherline is pretty flimsy
[01:01:20] <Tom_itx> i've done quite a bit with it thru the years though
[01:01:55] <PetefromTn> That is exactly my problem with them... A lot of times my 12x36 lathe work makes me wish I had a much larger machine and I could chuck up the sherline lathe in it pretty easily...
[01:03:00] <Tom_itx> we had Tree, Fadal, Okuma and a couple others in the shop
[01:03:09] <Tom_itx> the Okuma are nice
[01:04:12] <PetefromTn> To be quite honest if I HAD to have a very small table top machine I would look to get a very nice CNC router table with around a foot of travel in each direction and get one beefy enough to machine aluminum. Then you can do some really cool stuff and have enough travel to enjoy it. There are some amazing little CNC routers available today and some are quite capable of machining aluminum.
[01:04:48] <PetefromTn> If I had not bought my Cincinatti Arrow 500 I was looking for a Fadal VMC. Fadals are nice machines and easy to maintain from most accounts.
[01:04:59] <Tom_itx> i'm not looking for a router
[01:05:08] <MattyMatt> denford had a dinky stepper driven toolpost
[01:05:35] <MattyMatt> that'd be easy enough to retrofit to any old lathe
[01:06:03] <Tom_itx> Fadal are lower end but they do well on aluminum
[01:06:05] -!- tmcw has quit [Remote host closed the connection]
[01:06:18] <MattyMatt> I guess you could survive without a brake if it was worm drive
[01:06:26] <PetefromTn> Someone need to make a really heavy duty CNC router that is a largish table top model out of steel or cast iron that comes in at say 2-300 lbs and can cut steel a bit.... That would be a sweet machine. My pal Art made a nice aluminum one he calls the nightmare and he loves it.
[01:06:33] <MattyMatt> brake/dogclutch
[01:07:13] <PetefromTn> Huh? I have a friend local who has a Fadal 6030 and all he does with that machine is make steel moulds...makes some good money with it too. Damn fine machine....
[01:07:47] <Tom_itx> they're ok
[01:07:53] <PetefromTn> Most of the moulds he makes he needs to load the machine with a forklift!!
[01:07:55] <Tom_itx> they don't hold up as well as others
[01:08:10] <PetefromTn> That's absolutely not what I have heard....
[01:08:10] <Tom_itx> we had 2 pallet changers on one of the Okumas
[01:08:15] <Tom_itx> with dual toumbstones
[01:08:49] <PetefromTn> You're talking a $500k machine there....
[01:08:56] <Tom_itx> i know

[01:17:47] <Tom_itx> and i was there helping him from the beginning

[02:10:39] <failsafe247> I am not really sure though
[02:10:48] <failsafe247> I am mostly concerned about picking the correct branch for easy future upgrades
[02:10:59] <failsafe247> Also, the reason I am using it is because I already built a full linuxcnc 3 axis cnc router based around a celeron 847 board
[02:11:13] <failsafe247> I am following the excellent writeup: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?NewRTInstall and have reached the part where I need to track a branch

[03:21:13] <Connor> failsafe247: Or are you enclosing the whole machine ?
[03:21:16] <failsafe247> The entire router is going to have a 1/4" plexiglass case surrounding it. It has a hinge that attaches to the big red box part.

[03:22:51] <failsafe247> nice Connor. I used a Roland CNC router with an enclosure like that. I wanted to be able to get to all sides of my setup
[03:23:43] <failsafe247> ahh it wasnt a Roland, now I dont remember the name....
[03:24:27] <Connor> I want to get a aluminum exterusion like yours for my router top..
[03:24:50] <Connor> to be honest.. the router itself probably could be rebuilt with all alumn parts without much difficulty..
[03:26:40] <Connor> I would redo the main rails a bit..make them longer and bring the gantry straight down instead of that angle.. giving more distance on the gantry.
[03:28:50] <failsafe247> Well if I was to do it again, I wouldnt have gotten this Chinese 6040 Router either
[03:29:13] <Connor> What's the Z range ?
[03:29:23] <failsafe247> Also, now I remember about that other router. It was a Denford 6600 or 2600 with enclosure

[03:48:31] <failsafe247> Well guys I am going to be afk till morning. I just wanted a short description of the pros and cons of picking the one Xenomia LinuxCNC branch over the other. Ill check in the AM to see if anyone commented. Thanks again.
[03:48:33] <PetefromTn> Honestly it is all over the place and while I probably could it would take as much time as replacing the bottom skins and I would still be left with a cheesy piece of metal. Been thinking about also going with some kinda fogbuster so I can make chips while I work on the trays...
[03:49:50] <Connor> Epoxy?
[03:53:00] -!- krusty_ar has quit [Ping timeout: 272 seconds]
[03:54:14] <PetefromTn> Yeah I dunno.... I thought about it...I would have to sandblast them and tig weld the worst holes then spray it on THICK to keep it from rusting.....
[03:56:18] <PetefromTn> Just got pretty down when I looked at them this afternoon...
[03:56:40] <Connor> might be cheaper than welding a new bottom in place.. and probably would last longer
[03:57:46] <Connor> Can't believe the dumba$$ left it with coolant in it all that time for it to rust out.

[03:58:12] <PetefromTn> yeah pisses me off.... but whatryagonnado?
[03:58:39] <Connor> Yea. No sense in crying over spilled coolant.. I mean milk..
[03:59:17] <Connor> You can make your own fog buster pretty cheap.
[03:59:59] <PetefromTn> really? do you have one?
[04:00:11] <Connor> but, I have no doubt you'll get them fixed pretty quickly.
[04:00:45] <Connor> No. just my little pump from the Harbor freight Parts washer.. but, I've seen threads on making them.

[11:14:25] <jkopal> Hello I have question. I want to make my own CNC. I have already made a driver board for step motors interconnected with an FPGA board. I would like to use an USB serial port to send a frame representing paralel bits (provided to the hal interface) to FPGA. Is there any similar project where I can take an inspiration from ?? I need to make this layer and I dont know where to start.
[11:17:44] <jthornton> for USB the downstream device must have the motion controller in it
[11:20:41] <cpresser> jthornton: USB doesn _not_ offer realtime capabilities since it is based on polling
[11:20:58] <jthornton> right
[11:21:11] <jthornton> that's why the smarts needs to be downstream
[11:21:19] <jthornton> morning
[11:22:00] <cpresser> an doing the motion-controller on an fpga is a lot of work
[11:22:19] -!- odogono has quit [Quit: odogono]
[11:22:31] <jthornton> I like the BIG EASY button that LinuxCNC has

[12:06:40] <jkopal> Well the motion controller is not big deal how ever the G code interpreter is. This I would like to avoid. I was thinking about sending a frame representing the paralel bus out and have a synchronization fifo and timing block inside the FPGA. In the moment I have inside NIOSII processor and VHDL is no problem for me. In contrary to the linuxs HAL
[12:08:53] <cpresser> HAL is basically the same as VHDL :)
[12:09:19] <cpresser> HAL does connect function blocks via pins. easy as that
[12:12:19] <jkopal> ok where to start to understand how to exchange data between HAL and serial port ???
[12:12:39] -!- Felix29 [Felix29!Felix@c-71-193-105-131.hsd1.in.comcast.net] has joined #linuxcnc
[12:12:48] <jkopal> for this I will need own driver right or not ??
[12:13:54] <cpresser> as far as i know the serial port also is non-realtime
[12:14:22] <cpresser> the parport however has a realtime kernel-module. as do the various mesa-fpga-controller cards
[12:14:51] <cpresser> but you can use the serial-port for non critical applications (i use mine for a DRO)
[12:16:45] <jkopal> well who cares if it is realtime when the stream will be bufered and FPGA will take care about the timing ???
[12:18:03] <cpresser> so you want to only use the gcode interpreter?
[12:18:10] <cpresser> (on the pc)
[12:18:16] <jkopal> exactly ....
[12:18:42] <cpresser> you dont need HAL for that.
[12:18:47] -!- kmrhb has quit [Ping timeout: 260 seconds]
[12:19:04] <cpresser> however, i cant give you mor hints on this. its beyond my scope of understanding linuxcnc internals
[12:19:06] <jkopal> so any advise what to do ???
[12:19:12] <cpresser> read the code
[12:19:34] <cpresser> figure out how the motion-planner interacts with the gcode parset
[12:20:46] <jkopal> ok I will try. My problem is that I am not very skilled in C
[12:21:07] <cpresser> this is not a simple project. it will require lots of reading and tinkering. depending on your final goal it might be way easier to use the motion controller of linuxcnc
[12:22:06] <cpresser> if you insist on using your FPAG board, add a PCI or PCIe interface :)
[12:24:15] -!- carper64_lb [carper64_lb!~quassel@] has joined #linuxcnc
[12:24:19] <jkopal> Mainly my problem is that that all my computers are portable :)
[12:25:23] <cpresser> lightning and pcmcia also qualify
[12:26:38] -!- ravenlock has quit [Ping timeout: 272 seconds]
[12:27:26] <cpresser> if the computer does not need to be portable, get a simple and cheap intel-atom mainboard. saves you a lot of trouble :)
[12:27:27] <jkopal> at the end it is always a problem once I plug it to the computer ... on the OS side I am lost ... using PCI instead of serial does not help much ....
[12:28:12] <cpresser> if you are lost on the OS side i would recommend to use a simple and proven setup^^
[12:29:15] <jkopal> yes you are right but I would like to learn it any way just I dont know where to start ...
[12:31:37] <cpresser> intel-atom-board + parport-breakout (ebay). done
[12:31:54] <cpresser> there is even an GUI (stepconf) for that
[12:32:18] <cpresser> once you got that running, you can take further steps
[12:35:18] <jkopal> engines are runing there is no problem in that, I just need to feed them :)

[12:55:15] <jdh> I wonder why
[12:55:31] <alex_joni> anyone knows what algorithms was used for encoding passwords in /etc/passwd (e.g. before /etc/shadow appeared) ?
[12:56:32] <jdh> crypt(3) ?
[12:57:22] <alex_joni> jdh: for crypt I get the modern thingie (with salt, etc)
[12:58:54] <jthornton> hi Alex
[12:59:02] <jdh> I thoguht salt was always there
[12:59:58] <alex_joni> jdh: this is pre /etc/shadow
[13:00:10] <alex_joni> it looks like standard DES 48/64
[13:00:16] <alex_joni> hi jthornton
[13:03:23] <ProxDem> des or md5
[13:05:47] <ProxDem> afaik crypt(3) DES
[13:06:41] -!- sparr has quit [Ping timeout: 245 seconds]
[13:08:10] <jdh> I thought shadow was just added fs perms, not a different crypt method
[13:08:21] <ProxDem> dunno how old your /etc/passwd is or where it comes from but I do believe jdh is correct on the salt being in /etc/passwd
[13:09:20] <ProxDem> nowadays in /etc/shadow you have the # reference for md5...blowfish sha256 sha512
[13:09:30] <ProxDem> so it makes it easier to identify =)
[13:09:42] <jdh> On a system without shadowed passwords (typically older Unix systems dating from before 1990 or so), the passwd file holds the following user information for each user account:
[13:09:43] <jdh> Username, Salt combined with the current hash of the user's password (usually produced from a cryptographic hash function)
[13:11:07] <ProxDem> most people don't realise the salt is there in /etc/passwd because it's not delimited by : IIRC
[13:12:35] <ProxDem> err $
[13:12:58] <ProxDem> replace : with $ lol

[19:54:09] <FinboySlick> GammaX: PARPORT: ERROR: request_region(0xcf00) failed Sounds to me like it's the root of your problem.
[19:54:47] <GammaX> FinboySlick, so I could possibly try changin address for the parport in the script from big john?
[19:54:59] <MasterTengil> I can visualize toolpaths one by one, but I haven't found how to show the entire process
[19:55:30] <MasterTengil> seems to me that it would be a very usefull function so I suppose it should be in the program somewhere
[19:55:38] <FinboySlick> GammaX: It'd be a good guess though I have no experience with that sort of thing. It's just that from the dmesg, that is the first element in the chain tha fails.

[20:46:02] <havent007> yes it is
[20:46:10] <GammaX> heh I may be able to help...
[20:46:17] <havent007> that would be great GammaX
[20:46:32] <GammaX> when you say pin allocation what do you mean?
[20:46:53] <havent007> the switches dont react, they dont send the off signal back to AXIS
[20:47:19] <havent007> physically they do click, but I have no clue which Pin belongs to which switch

[21:04:46] <micges> tensaiteki: you need one hack in Axis to gentrivkins works properly
[21:06:37] <micges> for now press Shift + 4
[21:06:46] <micges> and you will jog properly
[21:07:39] <tensaiteki> shift 4 doesn't seem to have any effect....
[21:08:31] <tensaiteki> is Shift + 4 the hack? or that something else?
[21:09:27] <havent007> GammaX, the program is worth gold, but all switches show reaction as Pin 11, is that possible?
[21:10:27] <tensaiteki> I mean. I know under gantrykins Shift+4 switches between world and joint mode but there isn't even a world/joint menu option with gentrivkins that I can see

[21:33:43] <micges_> tensaiteki: you need add few sections more
[21:33:45] <failsafe365> I have 2 more questions though: 1) Are there performances advantages in the "master" branch relating to Xenomia kernel? Or does the Xenomia kernel perform equally well on the stable 2.5 branch and the master branch?
[21:34:00] <mhaberler> no change
[21:34:10] -!- micges has quit [Ping timeout: 245 seconds]
[21:34:22] <mhaberler> differences are all unrelated to rt performance
[21:34:26] <failsafe365> 2) Is there a wiki or forum post where I should post my results of using your code? Just trying to help out.
[21:34:45] <mhaberler> definitely - post a report on wiki.linuxcnc.org
[21:35:01] <mhaberler> it might help others until things are better documented and packages exist
[21:35:08] <micges_> tensaiteki: http://pastebin.com/YfAKk0V2

[21:35:30] <micges_> then it will obey limits
[21:35:38] micges_ is now known as micges
[21:36:20] <failsafe365> Okay will do. I still havent decided on which branch to use yet. I want to make sure I know why to pick one branch over the other. I havent found a feature list comparing the two. I tried reading the commits on Github, but I didnt really come to any conclusions.
[21:37:18] <failsafe365> It is going to be controlling an actual machine, so I might settle on the 2.5 branch due to stability...but dont really know yet
[21:38:31] <mhaberler> well ChrisM's gscreen is available in master only; also this stuff: http://www.linuxcnc.org/docs/devel/html/remap/structure.html
[21:39:00] <mhaberler> there are no stability issues I would be aware of - it might not be as polished as a formal release
[21:39:53] <mhaberler> and if there are any we find them mostly through somebody trying it ;)

[21:44:51] <failsafe365> I plan on running it headless and probably forwarding it over ssh so I can control it from my main desktop. Once I get everything sorted I'll post to the wiki and start a thread in the forums detailing my experiences.
[21:46:03] <failsafe365> I am also using a Hitachi wj200 VFD. I have connected a RS232 to RS485 adapter and plan on controlling it from linuxCNC. I am sure I will have plenty of things to talk about in my forum posts. I appreciate all your help so far though.

[21:49:55] <failsafe365> In the future, do you think that mainline linuxCNC will continue to use the RTAI kernel? Or do you think it will adopt the Xenomia kernel as its default configuration? I saw that RTAI was recently updated to be compatible with 3.X kernels..

[21:53:12] <failsafe365> I would think with the use of Xenomia on ARM based hardware that its use would increase. Especially if there is already a plan to separate the HAL layer from the User Input/Output layer.
[21:53:40] <failsafe365> As in running on completely separate machines.

[21:58:43] <alex_joni> failsafe365: the HAL layer was always separated
[21:58:56] <alex_joni> diginet: imagine a coordinate system attached to the tool
[21:59:04] <alex_joni> that coord system can rotate around ABC
[21:59:16] <alex_joni> but it's useful for easier g-code
[21:59:34] <diginet> UVW are rotational?
[21:59:42] <diginet> I thought they were linear
[21:59:51] <alex_joni> imagine the tool tilted and pitched and ..., now drilling along the tool direction is hard to describe in XYZ
[22:00:00] <alex_joni> but in UVW it's just a move along W
[22:00:09] <diginet> OHHHHH
[22:00:18] <diginet> so UVW refers to the movement of the bed?
[22:00:25] <alex_joni> nope
[22:00:31] <diginet> oh :(
[22:00:32] <Tom_itx> the tool head
[22:00:34] <alex_joni> it refers to what you want it to refer ;)
[22:00:38] <alex_joni> usually the tool head
[22:00:49] <diginet> but isn't that what xyz are for?
[22:00:52] <mhaberler> alex_joni: but not from user interfaces which happen to use HAL, which most do, so thats a bit theoretical
[22:01:04] <alex_joni> but it doesn't need to a). exist or b). make sense on many machines
[22:01:13] <alex_joni> mhaberler: no need for it to be the same HAL though ;)
[22:01:23] <diginet> the tool head moves in xy on a gantry, and the z axis is the bed moving up and down?

[22:03:25] <mhaberler> failsafe365: I dont know - I have some question marks wrt long-term viability of RTAI; with Xenomai there is a larger user base, wider range of architectures supported, and a clear strategy how to fold into rt-preempt, so that looks more likely to be a longer-term option

[22:05:14] <diginet> question number two, why are 6 axis machines seemingly much more rare than 5 axis ones?
[22:05:25] <Tom_itx> that shop is a couple miles from me
[22:05:27] <alex_joni> you mean for milling
[22:05:30] <alex_joni> diginet: ?
[22:05:41] <diginet> yeah
[22:05:43] <FinboySlick> diginet: 5 is typically enough, when you go for more, you usually don't stop at 6.
[22:05:47] <alex_joni> diginet: the tool is round :D
[22:05:50] <Tom_itx> but i've never been inside
[22:06:02] <alex_joni> diginet: doesn't make sense to spin around it
[22:06:08] <diginet> can you do everything you can on a lathe with a 6 axis cnc?
[22:06:24] <diginet> errr cnc mill
[22:06:44] <alex_joni> for a robot (e.g. welding robot) the tool is not centered and collinear with the 6th joint, so it makes sense to rotate around it
[22:07:04] <alex_joni> diginet: a *-axis cnc is not a lathe
[22:07:29] <alex_joni> even if you can do the same things, they are different tools with advantages and drawbacks
[22:07:35] <alex_joni> like speed, stability, etc
[22:07:39] <Tom_itx> i'd hate to pay the light bill on that cincinati
[22:07:56] <FinboySlick> diginet: Typically, more than 5 axis will incoporate one or two 'lathe' spindles.

[22:08:47] <diginet> well I mean I know practically speaking a traditional lathe might be better, but like, mathematically, doesn't 6axis mill have the same degrees of freedom? (plus the regular old cartesian ones)
[22:10:10] <alex_joni> FinboySlick: only the tools shown in that video probably cost more than a fairly nice machine
[22:10:41] <alex_joni> diginet: mathematically you have 2 axes + spindle on a lathe
[22:10:42] <FinboySlick> alex_joni: Yeah, that mill is well beyond pipe dream for most people here.
[22:10:54] <alex_joni> that means a 3-axis machine + turntable could emulate that
[22:11:19] <diginet> alex_joni: yeah, cylindrical coordinates, one polar, two linear
[22:11:45] <diginet> err
[22:11:57] <alex_joni> FinboySlick: the nicest I saw in person used a big-ish Kuka robot for tool storage
[22:12:08] <diginet> yeah, that
[22:12:09] <alex_joni> something around 200-ish tools
[22:12:29] <diginet> why are lathes generally horizontal instead of vertical?
[22:12:51] <alex_joni> the robot would fetch the tools for a certain job, load them on a pallet, which would then travel and get loaded in a machining center
[22:12:55] <Tom_itx> because 12' bars would require a tall building
[22:13:01] <alex_joni> Tom_itx: :D
[22:13:07] <Tom_itx> heh
[22:13:20] <alex_joni> and tall people to mount the stock
[22:13:38] <alex_joni> diginet: there are also carousels which are lathe-like, but vertical
[22:13:52] <Tom_itx> turret lathes etc

[22:26:38] <mhaberler> LinuxCNC will sport a binary package which already now runs on RTAI, Xenomai, RT-PREEMPT or a vanilla kernel unchanged (no RT guarantees on vanilla)
[22:28:28] <FinboySlick> Would RT-PREEMPT is what's in the later vanilla kernels?
[22:28:40] <FinboySlick> :s/is/be/
[22:29:16] <mhaberler> no, technically thats a different kernel build with better RT properties but otherwise identical interface
[22:29:50] <mhaberler> 'vanilla kernel' translates into 'simulator build' in the past
[22:30:06] <mhaberler> ah I see
[22:30:10] <FinboySlick> OK, still requires a patch, but uses standard interface to scheduling?
[22:30:24] <mhaberler> some kernels say 'PREEMPT' during boot - no, usually not
[22:30:52] <mhaberler> well it will likely go mainline, and there is one available stock for eg debian wheezy
[22:31:26] <mhaberler> so yes, the intent is to curb on linuxcnc-specific kernel fiddling wherever possible
[22:32:30] <mhaberler> re scheduling.. there are quite a few different schedulers available nowadays, I'd need to look what is being used atm, but yes its pretty much a standard linux ABI used
[22:33:24] <FinboySlick> mhaberler: I noticed some new stuff with 3.x kernels with respect to realtime scheduling. I was hoping it would make deterministic realtime patches obsolete.
