Back
[00:00:54] <furrywolf> your simplification isn't reflecting the actual linkage...
[00:01:36] <pcw_home> I'll bet if you look on the other side you will see the stress riser on the top instead of the bottom of the hole
[00:01:47] <furrywolf> also, you can't fix the entire radius of the hole in place. a pin only exerts force on, at best, 1/4 of the back of the hole. that pin isn't a press fit, and every one I've seen could only be described as a loose fit.
[00:02:32] <furrywolf> when you get it right, you'll see a second stress concentration at the weld between the pedal and the pivot bushing
[00:02:41] <pcw_home> which is what you would expect if the fork cannot rotate
[00:03:08] <SpeedEvil> furrywolf: exceptions I've seen are when a steel pin is forced into a greased undersized wooden hole. But...
[00:03:46] <furrywolf> SpeedEvil: when you find a car where the clutch pedal is made of greased wood with an undersized hole...

[00:06:39] <furrywolf> pcw_home: I think he's not going to get an accurate result until he models a pin and its constraints.
[00:07:12] <furrywolf> the way it's still showing the bending being at the fork instead of at the pivot well means it's still way off base.
[00:07:18] <furrywolf> weld
[00:08:48] <zeeshan> furrywolf: you're making me upset
[00:08:48] <zeeshan> lol
[00:08:51] <furrywolf> zeeshan: what's it look like if you don't fix the hole at all, and instead fix only the upper pivot from moving?
[00:09:14] <furrywolf> actually, never mind, that'll show a different stupid failure.
[00:09:18] -!- Akex_ has quit [Quit: Connection closed for inactivity]
[00:09:43] <furrywolf> the simulation may be right in one way... it is quite likely this thing will break if you stomp on it. :P
[00:09:46] <zeeshan> =P
[00:10:02] <furrywolf> 3/8 by 1.5 does seem a bit thin for how much force you're putting on it.
[00:10:12] <zeeshan> thats what the stock pedal is :/
[00:10:22] <zeeshan> maybe the problem is im overestimating the force
[00:10:28] <furrywolf> is the stock pedal aluminum or steel? and do you put 150lbs of force or 15lbs of force on it?
[00:10:30] <zeeshan> theres no way i was applying 150lb for my clutch pedal
[00:10:32] <zeeshan> that'd destroy me
[00:10:37] <zeeshan> i think its more like 50lb.
[00:10:52] <furrywolf> I think even my truck is less than 50.
[00:11:19] <zeeshan> im asking my buddy to take his weigh scale
[00:11:26] <zeeshan> and put it between his foot and his pedal and tell me the number
[00:11:27] <zeeshan> lol
[00:11:43] <furrywolf> lol
[00:12:23] <furrywolf> I have a 70lb postal scale, but last I tried it it didn't turn on. probably needs a battery. but it's all plastic, and thin plastic at that... I'd need to sandwich it between two blocks of wood to keep it from just cracking.
[00:12:31] <postaL> that's a big scale.
[00:13:24] * zeeshan waits :p
[00:13:27] <furrywolf> is there room to re-engineer it? say, use a longer pivot tube, with the pedal straight and not bent, and a second tab welded to the tube for the pushwod?
[00:13:29] <furrywolf> pushrod
[00:13:45] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[00:14:43] <zeeshan> haha
[00:14:46] <zeeshan> he's like "wtf"
[00:14:50] <zeeshan> hes trying it
[00:14:59] <zeeshan> furrywolf: yea it looks like ill hjave to make that section wider
[00:15:03] <zeeshan> and use a custom fork
[00:16:41] <Crom> well the reprap is moving
[00:16:41] <furrywolf> you say "yeah", but that has nothing to do with what I asked. :P
[00:17:02] <Tom_itx> pcw_home you around?
[00:17:44] <zeeshan> the pedal position can't be changed
[00:17:47] <zeeshan> the pedal can be made thicker
[00:18:20] <pcw_home> yeah
[00:18:26] <Tom_itx> pcw_home, on the ADC on the 7I47S, i've hooked it up with 10V on the Analog+ and GND on Analog-. with a command speed of S5000 M3 i get a pulse from the Analog out then it goes low
[00:18:36] -!- Valen [Valen!~Valen@c211-30-128-202.blktn6.nsw.optusnet.com.au] has joined #linuxcnc
[00:18:44] <furrywolf> so there's no room at all to the right of the assembly?
[00:18:49] <Tom_itx> i tried both the 1.4khz and 5khz frequencies
[00:19:45] <zeeshan> whatcha mean?
[00:19:48] <zeeshan> "To the right?"
[00:19:54] <zeeshan> please refer to this image haha so i dont get confused
[00:20:06] <zeeshan> http://i.imgur.com/TCS3zWn.png
[00:20:38] -!- per_sonne_ has quit [Ping timeout: 252 seconds]
[00:21:23] <furrywolf> ... to the right. of the car.
[00:21:32] <zeeshan> you see the image
[00:21:36] <zeeshan> you see how its attached
[00:21:39] <zeeshan> :-)
[00:21:42] <pcw_home> Hmm if you have 10V and enable (active low) and PWM you should get output
[00:21:46] <zeeshan> its a matter of making the pedal thicker
[00:21:53] <zeeshan> and making a custom fork
[00:21:58] <zeeshan> or............
[00:22:08] <zeeshan> throwing this all in the garbage!
[00:22:13] <furrywolf> ok, if you want to start with that image. extend the pivot tube out the right side of that box, and attach the pedal there. inside the box, just have a tab down to the fork. but do you have room there?
[00:22:56] <Tom_itx> maybe enable is high
[00:22:59] <Tom_itx> lemme check that
[00:23:14] <Tom_itx> can i invert that if i need to?
[00:23:18] <zeeshan> no room
[00:23:23] <zeeshan> itll hit steering shaft
[00:23:31] <pcw_home> enable has to be low (yes set the invert option)
[00:23:51] <Tom_itx> i might have to reverse that, i'll check
[00:24:02] <pcw_home> I dont remember the PWM polarity off hand
[00:24:23] <pcw_home> but it may need to be inverted also
[00:24:27] <Tom_itx> i think i inverted that on the other board and left it that way for this one
[00:24:28] <zeeshan> i was really hoping to avoid making a new Fork
[00:24:28] <zeeshan> ;/
[00:24:36] <zeeshan> but its relatively easy to machine
[00:26:03] <furrywolf> make a second plate that bolts onto your pedal, and goes over the fork?
[00:26:30] <zeeshan> i was thinking that
[00:26:38] <zeeshan> trying out the .5 thick plate first
[00:27:04] <furrywolf> does the stock pedal have the sideways bend in it, or is that a result of your new location?
[00:27:06] <zeeshan> looks like .5" plate works
[00:27:15] <zeeshan> it has the bend sideways
[00:27:18] <zeeshan> but its not extended 4" back
[00:27:25] <zeeshan> that makes a pretty big difference :/
[00:27:28] <furrywolf> and is the stock pedal alu or steel? I know every vehicle I've own has been steel...
[00:27:30] <Tom_itx> fixing /ENA fixed that
[00:27:31] <Tom_itx> thanks
[00:27:33] <zeeshan> aluminum
[00:27:50] <zeeshan> w/ a 1/2" plate
[00:28:03] <zeeshan> with 100lb force on the pedal , im seeing 35959 psi
[00:28:05] <zeeshan> thats better!
[00:30:49] <zeeshan> pedal is .82 lb not bad
[00:31:04] <furrywolf> that's pretty light.
[00:31:15] <zeeshan> if i didnt have to weld a spacer thing
[00:31:20] <zeeshan> i coulda used 7075
[00:31:27] <zeeshan> and not have to worry about any of this nonsense! :P
[00:31:57] <zeeshan> friend just got back to me
[00:31:58] <zeeshan> 60lb
[00:32:01] <Tom_itx> ok with pwm set to 5khz i had to half the scale but i haven't hooked the motor up yet to check if it's at the commanded speed
[00:32:17] <Tom_itx> it's 'in the ballpark'
[00:33:04] <furrywolf> make it from good alloy steel. machine it out of a leaf spring. :P
[00:33:20] <XXCoder1> Make it from titanium'
[00:33:22] <pcw_home> it should linear with 1% at 5 KHz
[00:33:26] <zeeshan> okay at 60lb
[00:33:27] <Tom_itx> pcw_home, if the pwm is inverted, it will run fast with a slow commanded speed right?
[00:33:30] <zeeshan> theres a factor of safety of 2.5
[00:33:31] <zeeshan> good enough
[00:33:36] <pcw_home> yes
[00:33:38] <Tom_itx> ok
[00:33:44] <Tom_itx> that's easy to check
[00:34:11] <Tom_itx> i'm getting nearly 10v at a S5000 which is about what i want
[00:34:25] <Tom_itx> just need to check the low end
[00:34:54] <furrywolf> zeeshan: what software are you using for all of this anyway?
[00:35:09] <zeeshan> ansys
[00:35:13] <pcw_home> the OP Amp is rail-rail but not perfect of course
[00:35:21] <Tom_itx> this sure makes a cleaner install than the other board
[00:35:25] <Tom_itx> yep
[00:36:49] <zeeshan> yea i just did a simulation on th stock pedal
[00:36:52] <zeeshan> and its way less stressed
[00:36:58] <zeeshan> that 4" extension makes a big diff
[00:37:04] <zeeshan> ;/
[00:37:12] <zeeshan> looks like stock factor of safety was around 2.5 as well
[00:37:38] <furrywolf> that's good, then. yours is just as strong as stock.
[00:38:35] <furrywolf> ansys looks ungodly expensive.
[00:40:35] <zeeshan> thank god for student license!
[00:40:45] <zeeshan> an alternative i use a lot is abaqus
[00:40:48] <zeeshan> thats a bit reasonable.
[00:40:54] <zeeshan> abaqus standard that is
[00:41:56] <pcw_home> man, even the sheep would not eat these bran muffins
[00:41:58] <pcw_home> swear they are made of sawdust soaked in fruit juice
[00:41:58] <furrywolf> anything that, rather than you buying, they only let you select to have a sales rep contact you, is overpriced.
[00:42:19] <zeeshan> fea is a joke to program
[00:42:31] <zeeshan> the hard part is how to generate the mesh
[00:42:38] <zeeshan> im sure theres tons of open source software out there to do that
[00:43:16] <furrywolf> I've generated meshes on 3d objects for 3d rendering purposes...
[00:43:20] <SpeedEvil> A ~1" tube on the rod, press-fitted into a very undersized hole in the Al might work OK
[00:44:14] <SpeedEvil> Or threaded at the end, with a nut to clamp it on.
[00:44:21] <SpeedEvil> (and a safety wire)

[00:47:07] <furrywolf> other than that... :P
[00:47:32] <zeeshan> furrywolf:
[00:47:35] <zeeshan> problem is solved
[00:47:39] <witnit> it might be a little high price, but it looks rather complete, takes a long time to gather all the right pieces
[00:47:39] <zeeshan> using my old design :]
[00:47:50] <furrywolf> what was the problem?
[00:48:07] <zeeshan> well it was twisting and bending too much right?
[00:48:09] <zeeshan> so just needed gussets
[00:48:56] <zeeshan> bah.
[00:49:04] <furrywolf> ... you do know several people here suggested making it wider, right? :)
[00:49:05] <zeeshan> its cause it was set to 60lb not 100 :/

[01:57:12] <furrywolf> got a paslode impulse framing nailer, battery, charger, non-mar tip, 6 fuel cells (although only 2.5 of them seem to be full), and a box and a half of nails for $25.
[01:57:26] <furrywolf> I would have haggled, but he even drove them here.
[01:57:29] <zeeshan> fuel cells? :]
[01:57:58] <furrywolf> that's what paslode calls them.
[01:58:06] <furrywolf> they're little butane canisters with an inflated price tag
[01:58:29] <furrywolf> it's an older model, but as long as it works...
[01:59:17] <zeeshan> cool
[01:59:25] <zeeshan> youre addicting to craigslist finds
[01:59:30] <zeeshan> and flea markets!

[01:59:44] <furrywolf> no. I do not go to flea markets. I do not like flea markets.
[02:01:01] <furrywolf> in theory, flea markets are where random people take their junk to sell it, like a big garage sale. in reality, flea markets are populated entirely by dealers who travel to flea markets to try selling their overpriced crap because they want to run a thrift store but don't want to deal with pesky things like a business license or paying taxes.

[02:02:19] <t12> sweet stuff shows up at fleamarkets if you are on your game
[02:02:27] <t12> i got a set of brown and sharpe toolmakers vises
[02:02:28] <t12> for $5 ea
[02:02:41] <Tom_itx> pcw_home, could i need a pullup on the opto out? on the /ENA i had to set it to acive low but i've got a relay on the pin. I reversed the relay leads but it still enables the relay all the time
[02:02:54] <t12> things like boxes of small C clamps for a buck each
[02:03:04] <furrywolf> the flea market here is the same dealers, every single time.
[02:03:06] <t12> more obscure useful tools often show up
[02:03:11] <furrywolf> I usually leave empty-handed.
[02:03:14] <t12> depends on the market really
[02:03:27] <furrywolf> they know they're useless and not going to sell anything, so they charge you to get in the door.
[02:03:38] <Tom_itx> pcw_home, currently the Optoout - is set to GND and the Optoout + goes to the relay with the other leg of the relay to +5v
[02:03:38] <furrywolf> just to make sure they get your money even when you realize it's all dealers with overpriced crap.
[02:04:54] <furrywolf> I always slip in through the back, just so I don't get pissed off at spending money to not get anything. lol

[02:07:28] -!- antcat has quit [Ping timeout: 245 seconds]
[02:08:19] <furrywolf> the charger doesn't seem to like the battery, and it's got corrosion by the contacts, so I'm guessing mine didn't actually come with a battery either. will need to rebuild it.
[02:11:34] <HSD> So before I go too far down this road... Anyone ever put LinuxCNC on a chrome box? Am I wasting my time?
[02:11:47] <furrywolf> chrome box?
[02:12:12] <furrywolf> heh, the charger declares the battery fully charged... putting a load on it, it drops from 6.5v to 2v in about 3 seconds.
[02:18:07] <furrywolf> I guess I need to try rigging up some contacts for it and trickling it for a while, but it's probably toast.
[02:18:24] <furrywolf> I might get enough of a charge into it to test that the rest of the gun works, however, and thus it's worth fixing the battery.

[02:49:33] <zeeshan> with no welds on it except at the bushing thing
[02:49:40] <furrywolf> what about using 3/8, and welding a second tab from the right side of the pivot tube to the middle of the 35 degree bend?

[03:01:20] <zeeshan> yes

[03:02:06] <zeeshan> maybe not :/
[03:02:10] <zeeshan> now that i think about it
[03:02:14] <zeeshan> that sounds similar to my stiction issue

[03:04:20] <Tom_itx> i removed that board you sent and added a couple relays to try this 7i47s
[03:04:41] <Tom_itx> i think either one will work ok
[03:05:16] <Tom_itx> i had to do some rewiring since the dac is on certain pins on the mesa card

[03:21:14] <HSD> furrywolf, hmm... mesa's ethernet cards?
[03:21:43] <HSD> could be an issue unless it comes in micro pcie style boards

[04:22:02] <Tom_itx> i figured it out but i had to add a pullup
[04:22:20] <pcw_home> a pull up should not be needed
[04:22:31] <Tom_itx> it's how i'm using it that its required
[04:22:43] <pcw_home> OK
[04:22:56] <Tom_itx> by itself the /ENA is fine but i'm also using a relay to drive the inhibit on the driver board
[04:23:20] <Tom_itx> it gives me a little deadband to switch from FWD to REV and not blow out the relay contacts
[04:23:28] <Tom_itx> just a few ms
[04:24:31] <Tom_itx> if i tried adding PID to this, what terms should i start adjusting?
[04:25:07] <pcw_home> velocity loops are usually just P and I
[04:25:29] <Tom_itx> what sort of numbers should i start with?
[04:25:56] <Tom_itx> i generally start with P and get it to overshoot then add I
[04:26:06] <Tom_itx> after backing P off a bit

[04:46:34] <pcw_home> The pwmgen will be scaled in RPM as will the commanded speed but the feedback speed needs to be scaled
[04:47:40] <pcw_home> (since encoder velocity output will be scaled in RPS not RPM)
[04:48:20] <pcw_home> so a scale component with a scale factor set to 60 is needed
[04:48:34] <Tom_itx> i may already have one i can use
[04:48:55] <Tom_itx> since i'm displaying the rpm
[04:49:54] <pcw_home> yeah re-use that one
[04:51:52] <Tom_itx> oh...
[04:52:06] <Tom_itx> how does pid work when you give it an M4?
[04:52:23] <zeeshan> http://www.amazon.com/Soondar%C2%AE-Powered-Thermometer-Temperature-Sensor/dp/B0054U4YKI/ref=cm_cr_pr_pdt_img_top?ie=UTF8
[04:52:24] <zeeshan> hmm
[04:52:27] <Tom_itx> are they unsigned?
[04:52:29] <zeeshan> i wonder if i can use this to datalog temp
[04:52:50] <pcw_home> yes they are signed
[04:53:13] <Tom_itx> won't that screw up the PID loop?
[04:53:44] <pcw_home> ( well motion now has signed and unsigned spindle outputs )
[04:53:50] <Tom_itx> this isn't because i need it btw... it's a learning exercise
[04:54:19] <pcw_home> encoder velocity is signed...
[04:54:37] <Tom_itx> that helps
[04:55:57] <Tom_itx> i've had enough for one day..
[04:56:24] <pcw_home> because of the delay between forward and reverse funny thing may happen at very slow speeds
[04:56:37] <pcw_home> funny things
[04:57:06] <pcw_home> so probably better to not set very slow spindle speeds
[04:57:09] <Tom_itx> because of my inhibit?
[04:57:25] <Tom_itx> i can't set anything below S250 or so
[04:57:58] <Tom_itx> and the result is around 90 rpm
[04:58:10] <Tom_itx> on the high end, it's alot closer
[04:58:21] <pcw_home> yeah because of the PID gain you might get a reverse PID/DIR output even for a forward direction
[04:58:51] <pcw_home> probably setting off an oscillation
[04:59:40] <pcw_home> ( you will undoubtedly find out )
[04:59:58] <Tom_itx> i'm sure
[05:00:19] <pcw_home> anyway

[14:42:19] <pcw_home> I'm running linuxcnc on 14.04, its pretty easy with 2.7/Preemt-RT
[14:42:20] <pcw_home> but probably not suited to parallel port interfaces due to Preemt-RTs' greater latency
[14:46:10] <JT-Shop> what does the RT-Preempt kernel do vs the normal one?
[14:47:53] -!- anth0ny_ has quit [Quit: anth0ny_]
[14:48:08] <pcw_home> well there are three common free linux real time kernels , RTAI, Xenomai and Preemt-RT
[14:48:10] <pcw_home> all have somewhat different real time characteristics but in most cases the order above is from least to most jitter
[14:49:45] <pcw_home> For example the system I am on has about 15 usec of jitter running RTAI but about 32 usec running Preemt-RT
[14:50:41] <zeeshan> pcw_home: a little while ago i briefly remember you guys talking about issues with q1900 by asrock
[14:50:45] <zeeshan> are those issues resolved? :P
[14:51:03] <JT-Shop> pcw_home, thanks
[14:51:29] <pcw_home> Yeah there were USB issues with the first Wheezy ISO and Baytrail CPUs (J1800,1900 etc)
[14:51:58] <zeeshan> im finally getting the 1900
[14:52:06] <zeeshan> when i install the new live cd
[14:52:10] <zeeshan> will i go through the same issues? :P
[14:52:17] <pcw_home> those are fixed (and have com back with newer CPUs)
[14:52:57] <pcw_home> No, the current ISO will boot on a AsRrock J1900
[14:54:52] <zeeshan> sweet
[14:55:02] <pcw_home> The current Wheezy ISO will not boot on newer CPUs like the 2957U in the HP stream mini
[14:55:34] <pcw_home> http://store.hp.com/webapp/wcs/stores/servlet/us/en/pdp/desktops/hp-stream-mini-desktop---200-010-p-k5g59aa-aba--1
[14:55:59] <pcw_home> but Ubuntu 14.04 will (as will Jessie)
[14:57:27] <zeeshan> okay so basically run 14.04 vs debian
[14:58:22] <pcw_home> If you want to futz about, but easiest is to just run the Wheezy ISO
[14:59:24] <pcw_home> unless you need a newer kernel for some reason (like new hardware not supported by the 3.4.9 kernel that comes with the ISO)

[15:08:05] <Tom_itx> i pulled my 10.04 off the 525 and plugged it right into the asrock board just fine
[15:08:05] <zeeshan> i just need to order a stick of ram
[15:08:09] <zeeshan> and the mobo yes?
[15:08:21] <Tom_itx> i got 2 ram
[15:08:34] <Tom_itx> that's about it unless you need a dvd
[15:08:35] <zeeshan> i dont think it needs more than 4gb
[15:08:38] <zeeshan> its my mill comp
[15:08:43] <Tom_itx> so?
[15:08:56] <Tom_itx> ram is cheap
[15:09:03] <zeeshan> i only use it to open web browser and stuff :P
[15:09:09] <zeeshan> for the longest time, my cad comp had 4gb
[15:10:00] <Tom_itx> i got 8 in each of these
[15:10:26] <Tom_itx> newegg had a mail in rebate a while back
[15:10:29] <Tom_itx> for 10 off
[15:10:42] <zeeshan> i really dislike mir
[15:10:51] <zeeshan> they send you one of those stupid prepaid visa cards
[15:10:57] <Tom_itx> i didn't mail mine
[15:11:59] <Tom_itx> i might stick this on the mill once i get the mill all ironed out
[15:12:05] <Tom_itx> it's gettin close now
[15:12:09] <zeeshan> can you mix and match ram
[15:12:17] <Tom_itx> i dunno
[15:12:20] <zeeshan> like have one stick of ddr3 1333 and another stick of 1600
[15:12:29] <archivist> depends!
[15:12:38] <zeeshan> on
[15:12:40] <archivist> see your board docs
[15:12:41] <Tom_itx> i never have tried
[15:12:51] <Tom_itx> it's supposed to i think
[15:12:57] <archivist> some channels have to match
[15:15:15] <zeeshan> "you may install varying memory sizes in channel a and channel b. the system maps the total size of the lower sized channel for dual channel config. any excess memory from the higher sized channel is then mapped from single channel operation"
[15:15:17] <zeeshan> whatever that means

[15:15:38] <zeeshan> i need more ram for my own desktop
[15:21:46] <zeeshan> okay i think ill do this
[15:22:04] <zeeshan> ill move the 2 sticks of ddr3 1333 ram from my desktop to the asrock
[15:22:17] <zeeshan> and buy 2 larger dimms for the desktop
[15:22:21] <zeeshan> 2 8gbs
[15:22:46] <zeeshan> i dunno why the dimm slots look so small on the q1900b :P

[16:14:58] <zeeshan> that i can get in a 6"x12" piece :p
[16:15:04] <zeeshan> i cant use wood cause i gotta bend it
[16:15:19] <zeeshan> maybe i can even get away with 1/4" for now
[16:15:45] <Tom_itx> plexi

[16:16:08] <zeeshan> just regular heat gun?
[16:16:10] <Tom_itx> i heat a steel rod and lay it over it
[16:16:11] <zeeshan> ive bent lexan before
[16:16:14] <zeeshan> never plexi
[16:16:24] <zeeshan> do you get that feel

[16:18:26] <zeeshan> how thick is that? looks like 3/16
[16:18:35] <Tom_itx> probably 1/8"
[16:18:59] <Tom_itx> you may need to heat both sides of 5/8
[16:21:21] <zeeshan> Tom_itx: i was wanting to ask you this a while back
[16:21:32] <zeeshan> in steel how much skin do you leave and in aluminuim how much
[16:21:42] <zeeshan> when you're doing a 2d shape on the mill out of a chunk of metal
[16:21:49] <zeeshan> and you want to manually rip it out?
[16:22:12] <zeeshan> ive been doing .015" for al, and i have to go around with a chisel to get it out
[16:22:13] <JT-Shop> lexan you can bend cold
[16:22:27] <zeeshan> JT-Shop: its easier to form a rear window of a car with heat
[16:22:28] <Tom_itx> .015 is a bit much
[16:22:38] <zeeshan> Tom_itx: what did you typically leave?
[16:22:43] <Tom_itx> .005 would hold it probably
[16:22:54] <zeeshan> ok ill sneak up to that number :P
[16:22:54] <Tom_itx> i can't because my table isn't completely flat

[17:15:42] <Jymmm> Loetmichel: With all those mods... Yes, yes you do =)
[17:15:56] <furrywolf> hrmm, you must live somewhere where vehicles are expensive.
[17:16:10] <Loetmichel> furrywolf: germany
[17:16:25] <Loetmichel> "roadworthy" is defined a little bit different here
[17:16:26] <furrywolf> it's pretty easy to pick up a sub-$500 vehicle here. I saw two good ones on craigslist free yesterday, needing less than a day of repairs...
[17:19:16] <Jymmm> furrywolf: But you live in the boonies. Not everyone has access to 40 acres of parking every dumptruck they find for $20 =)
[17:19:18] <furrywolf> http://humboldt.craigslist.org/cto/5007111006.html that's probably the best $500 car on craigslist right now. head gasket is easy.
[17:19:29] <furrywolf> (on the local craigslist)
[17:20:08] <Loetmichel> furrywolf: i repeat: germany...

[17:22:53] <Loetmichel> furrywolf: the german "tuev" has a strange definition of "roadworthy"
[17:23:25] <Loetmichel> you seldomly find a car that has more than a few weeks to the next "annual" left for less than 1000 eur
[17:23:44] <Loetmichel> tuev does the annual here
[17:24:15] <Loetmichel> and they can invalidate your license plate if they think the car isnt roadworhty
[17:24:29] <Loetmichel> and they do if so much as a single license plate light is not working
[17:25:22] <malcom2073> It's the same way in some states in the USA, but varies per state. Here it's like that, yearly inspections, but one state south no safety inspections
[17:26:14] <furrywolf> here they have to pass smog when you buy them, then after that as long as you don't piss any cops off too much, you can drive just about anything.
[17:26:26] <Loetmichel> malcom2073: what i wanted to say: thats the reason you seldomly find cheap used cars here
[17:26:44] <furrywolf> generally you'll only get dinged for broken/missing lights, etc, if you already pissed the cop off for some other reason but he needs something he can put on paper to pull you over for.
[17:26:48] <malcom2073> Yeah, if cars have a fresh inspection, they typically go for a LOT more
[17:27:03] <malcom2073> I'm actually gonna pay for a fresh inspection so it's easier to sell my bike heh

[17:30:19] <furrywolf> my suggestion would be analog mode and let linuxcnc close the loop. much easier timing requirements, easier tuning etc.
[17:30:29] <furrywolf> Loetmichel: lol
[17:31:04] <Loetmichel> btw: thats the bike in question: http://www.cyrom.org/palbum/main.php?g2_itemId=15295&g2_imageViewsIndex=1
[17:31:07] <zoni1983> is there any tunning required with step/dir
[17:31:08] <furrywolf> pcw is the exert on hooking servos up to mesa boards, but I suspect he'll say the same thing.
[17:31:20] <furrywolf> yes, you have to tune the drive. it probably has pots or something.

[17:33:07] <Loetmichel> as i said: i only have a car license
[17:33:27] <Loetmichel> that is allowed up to 50cc 50kmh bikes, too
[17:33:30] <Loetmichel> but not bigger
[17:33:42] <Loetmichel> and a bike license is in excess of 2000 eur here
[17:33:53] <Loetmichel> (~$2200 )
[17:34:17] <furrywolf> yeah, remind me to stay away from germany.
[17:34:26] <Loetmichel> totally not worth it for the few times i drive a bike a year
[17:34:43] <furrywolf> why the hell would you have to pay extra to ride a smaller, cheaper, more efficient vehicle? sounds like excessive government.
[17:34:51] <Loetmichel> as a tourist you can use your american license... for up to a year iirc
[17:35:26] <Loetmichel> but be careful on the autobahns. we drive up to 180 mph there regulary ;-)
[17:35:44] <furrywolf> "if we let them drive bikes, we won't collect nearly as much in fuel taxes... so let's jack up the price of the license to compensate!"
[17:35:52] <Loetmichel> ok, most more like 140mph ;-)
[17:36:01] <furrywolf> I don't know if anything I own goes 140. :P
[17:36:19] <furrywolf> truck goes 65mph if there's absolutely no wind and you're on level ground... sometimes.
[17:36:21] <Loetmichel> my car does
[17:36:26] <Loetmichel> barely ;-)
[17:36:40] <zoni1983> pcw_home: any suggestions
[17:36:54] <Loetmichel> it has a top speed of 230kmh
[17:37:06] <furrywolf> one of my subarus might, but I don't know if it'd be safe at those speeds. I stuffed in a substantially larger engine, but that doesn't help with the aerodynamics of an old station wagon... plus I put a lift kit on it, which probably doesn't help any at high speed either.

[17:38:30] <furrywolf> my van... no idea what its top speed is. it's the largest van ford sells, 15 passengers... it's not built for speed. :)
[17:38:35] <Loetmichel> i think that was sold as cadillac catera in usa
[17:38:53] <furrywolf> my other subaru would overrev around 100mph.
[17:39:06] <furrywolf> assuming it even made it there before drag exceeded power.
[17:39:39] <Loetmichel> i was totally surprised that the cruise control locks in at 140mph ;-)
[17:40:27] <Loetmichel> it does gurgle down a lot of fuel at that speed tho
[17:40:59] <furrywolf> heh
[17:41:02] <furrywolf> nothing I own is built for high speed.

[17:44:17] <Loetmichel> it was only sold as catera in the US

[17:47:14] <Loetmichel> the bus looks like the "a.team" car ;-)
[17:47:42] <furrywolf> that's not a bus. that's just a van. you have to go larger before we call them busses here. :P
[17:48:00] <Loetmichel> hihi, sorry, habit
[17:48:14] <Loetmichel> because the VW van is called "vwbus" here
[17:48:42] <furrywolf> we call them microbusses here. because they're kinda like a bus, but too small to be useful. (not to mention slow and ugly)
[17:48:46] * Jymmm puts Loetmichel on the short bus
[17:49:08] <Loetmichel> hmmm
[17:49:21] <Loetmichel> what are the mercedes "sprinter" called in the us?
[17:49:22] <furrywolf> as you can see, none of my vehicles were designed for high speeds.
[17:49:27] <furrywolf> sprinter
[17:49:38] <furrywolf> and they're ungodly fucking expensive, so no one owns one.
[17:49:49] <Loetmichel> the go about 110 mph here ;-)
[17:49:57] <Loetmichel> regulary ;-)
[17:50:15] <furrywolf> a van like I pasted sells for about $3000 in excellent condition. a sprinter of the same age, maybe $30,000. no one buys them because of this.
[17:50:30] <Loetmichel> and yes, that IS a nightmare to drive that at that speed, at least when empty
[17:50:39] <furrywolf> I'm sure my van can do 110. it's probably not doing 160. :P
[17:50:48] <Loetmichel> when you hit about 80mp the back axle starts to "swim"
[17:51:05] <furrywolf> freeway traffic here is about 70-75mph
[17:51:37] <furrywolf> too many people who can't fucking work an automobile to drive much faster. heh.
[17:51:48] <Jymmm> IF you come across super cheap hdmi cables, buy them. Cause those damn things are ungawdly expensive
[17:51:52] <Loetmichel> but properly loaded they do 110, even 120 mph perfectly well

[17:52:12] <furrywolf> I used to own a bmw 7-series... it was supposed to do 160 or something.
[17:52:21] <furrywolf> I got rid of it. utter shit car.
[17:52:52] <CaptHindsight> in Germany they expect drivers to actually know how to drive, over here anyone can get a license if they can look over the wheel at 16 or >
[17:53:02] <Tom_itx> how come bmw's don't come with a spare?
[17:53:14] <Tom_itx> i hear some don't even have a place for one
[17:53:14] <Loetmichel> furrywolf: my wife owns a bmw x1
[17:53:20] <Loetmichel> that can do 160mph
[17:53:45] <CaptHindsight> flat tires are also not allowed :)
[17:53:46] <Jymmm> Tom_itx: You don't need a spare when you can afford a $1200 tune up
[17:53:50] <Loetmichel> if it wasnt so small and if you would see something out the back it would be a nice car
[17:54:19] <Tom_itx> Jymmm, on a regular basis too...
[17:54:25] <Loetmichel> Tom_itx: they dont need one
[17:54:29] <Jymmm> Tom_itx: Yep.
[17:54:33] <Loetmichel> "runflat" tyres
[17:54:35] <Tom_itx> Loetmichel they do too
[17:54:43] <Tom_itx> runflat don't work
[17:54:50] <Loetmichel> it does
[17:54:52] <Tom_itx> my friend can vouch for that
[17:55:01] <Loetmichel> up to 30mph
[17:55:11] <Loetmichel> i tested it unwillingly
[17:55:16] <Tom_itx> do you do 30mph on the autobahn?
[17:55:26] <Loetmichel> if you have a flat you have to ;-)
[17:55:35] <Tom_itx> and get your arse run over
[17:55:37] <Loetmichel> so its written in the manual
[17:55:59] <Loetmichel> ahem, correction, 80kmh, so 50mph
[17:56:25] <Loetmichel> no, german autobahns are FAST but also more or less disciplined
[17:56:31] <Loetmichel> or it wouldnt work
[17:56:41] <furrywolf> my bmw had a spare
[17:56:51] <Tom_itx> furrywolf older ones did
[17:56:52] <Loetmichel> we have very few accidents here on the autobahns compared to the traffic
[17:57:29] <Loetmichel> furrywolf: newer BMW you can order either with a "instant repair/inflate" set or runflat tyres
[17:57:44] <Loetmichel> they dont even have a PLACE to store a spare any more
[17:57:45] <Jymmm> Loetmichel: How can you tell with the tractors just shoving the accidents to the side of the road?
[17:57:56] <Tom_itx> that's just silly
[17:57:59] <furrywolf> we have accidents everywhere here, because the average driver is a fucking idiot.
[17:58:28] <Loetmichel> furrywolf: we have some here also... idiots i mean
[17:58:59] <Loetmichel> especially the kind that pulls out behind a semi at 55mph and doesnt look in the review mirror...
[17:59:11] <Loetmichel> and me running up at 140mph...
[17:59:22] <Loetmichel> i have to state: my ABS works well ;-)
[17:59:34] <Loetmichel> tested it MORE than a few times ;-)

[22:18:10] <Tom_itx> using hostmot2 pwmgen
[22:21:33] <pcw_home> PID out goes to the PWMgen (which should be scaled in RPM)
[22:22:25] <pcw_home> so for example if you set FF0 to 1 and P,I,D, etc to 0 it should be the same as before (open loop)
[22:25:10] <pcw_home> that is with FF0 of 1 and everything else 0 else makes the PID component do
[22:25:12] <pcw_home> nothing but copy the command input (motion spindle speed out) to the PID output

[22:32:47] <pcw_home> yes you are just inserting the PID component in spindel speed chain
[22:33:11] <Tom_itx> i just wasn't sure where to plug it in
[22:33:26] <Tom_itx> and you say set FF0 to 1?
[22:33:26] <pcw_home> if you have P or I (without it should behave exactly as before)
[22:33:32] <Tom_itx> right
[22:33:45] <pcw_home> yes that make the PID a no--op
[22:33:50] <Tom_itx> set P & I to 1 and it will be neutral
[22:34:25] <pcw_home> no if P and I are 0 you should have identical behaviour as before
[22:34:52] <Tom_itx> Results in a contribution to the output that is the error multiplied by Pgain
[22:35:02] <Tom_itx> if Pgain is 0 the result will be 0
[22:35:11] <Tom_itx> not what it was input as
[22:35:37] <Tom_itx> if Pgain is 1 it shouldn't be affected unless i don't understand this PID loop
[22:36:19] <pcw_home> with FF0 of 1 the output will follow the input so if you command 500 RPM the PID output will be 500
[22:36:24] <Tom_itx> anything either side of 1 would be a decrease or increase to gain
[22:36:50] <Tom_itx> it's that way without pid
[22:37:31] <Tom_itx> i set FF0 to 1 for now
[22:37:41] <pcw_home> P = 0,I=0 ,FF0 = 1 for open loop (input is copied to output)
[22:37:44] <Tom_itx> but i'm not sure i understand why you set Pgain to 0
[22:37:51] <Tom_itx> mkay
[22:37:59] <Tom_itx> i would think P & I would be 1
[22:38:06] <Tom_itx> but i've never messed with this loop
[22:38:09] <pcw_home> FF0 is independent of P
[22:38:15] <Tom_itx> i get that
[22:38:33] <Jymmm> Goodyear, a Continental Company.
[22:38:53] <Tom_itx> but the command value is multiplied by the Pgain
[22:39:03] <Tom_itx> and if Pgain is 0 the command value will be 0
[22:39:05] <pcw_home> Nope
[22:39:15] <Tom_itx> but if it's 1 it will be command value out
[22:39:30] -!- Camaban has quit [Quit: Leaving]
[22:39:31] <pcw_home> the _error_ is multiplied by P
[22:39:45] <pcw_home> not the command
[22:39:47] <Tom_itx> i'll try it
[22:39:57] <Tom_itx> then increase P by .0xx numbers
[22:40:14] <Tom_itx> until it oscillates
[22:40:27] <Tom_itx> back off a couple and add I
[22:40:44] <Tom_itx> you don't think FF0 will contribute to the smoothness?
[22:40:47] <pcw_home> a P of 1 means that a 1 RPM error will result in a 1 RPM correction added to the FF0 value
[22:41:25] <Tom_itx> you just said P and FF0 were independent of each other :)
[22:41:36] <Tom_itx> or that's what i heard anyway)
[22:42:06] <pcw_home> They are but the output is the sum of FF0*Command and -P*Error
[22:42:40] <Tom_itx> so i'll leave FF0 at 1 and start I at 0 and P at some 0.0xx value
[22:43:10] <Tom_itx> where it needs the most boost is at low rpm
[22:43:21] <Tom_itx> high rpm are not too far off comparatively
[22:43:26] <pcw_home> Yeah depending on the various delays you may be able to use P in the 10s to 100s
[22:43:38] <Tom_itx> that much?
[22:43:42] Jymmm is now known as Red70sShow
[22:43:46] Red70sShow is now known as Jymmm
[22:44:09] <pcw_home> well you also depend on I
[22:44:14] <Tom_itx> that won't overshoot the midrange where it's pretty close?
[22:45:00] <pcw_home> if theres little error, P wont do much...
[22:45:17] <Tom_itx> i don't expect to get good results much below 150rpm
[22:45:33] <Tom_itx> it may surprise me..
[22:46:10] <Tom_itx> right now with S300 i'm getting around 140rpm
[22:46:12] <pcw_home> no, and its tricky to tune non servo drives (since you can apply instant reverse force)
[22:46:22] <pcw_home> cant apply
[22:46:53] <Tom_itx> i bet there's .25 sec delay from fwd to rev
[22:47:58] <pcw_home> and I'm not sure if accel/decel torques are equivalent
[22:48:29] <pcw_home> so simple drives are not so simple to tune
[22:49:01] -!- per_sonne_ has quit [Ping timeout: 255 seconds]
[22:49:50] <pcw_home> I guess I would just add P until it gets unstable and then use about 1/2
[22:49:52] <pcw_home> and then do the same with I
[22:50:05] <Tom_itx> do i use setp with those or net?
[22:50:14] <Tom_itx> ie pid.0.command
[22:50:45] -!- gonzo_nb has quit [Remote host closed the connection]
[22:50:45] <pcw_home> setp (or better still use the calibrate routine so you can play with them live)
[22:51:09] <Tom_itx> not aware of that
[22:51:41] <Tom_itx> cmd line?
[22:51:49] <pcw_home> pid.0.command needs to be netted to motion spindle speed out
[22:52:29] <pcw_home> just steal you current direct spindle speed to PWM net

[22:53:26] <Tom_itx> yeah i'm sticking the pid between spindle speed now
[22:53:40] <pcw_home> parameters need to be in the ini file for calibrate to find/use them
[22:54:49] <pcw_home> calibrate can save your changes to the ini file when done so thats handy
[22:56:00] <Tom_itx> should this be in the ini?
[22:56:04] <Tom_itx> i've got it in hal right now
[22:57:17] <pcw_home> they advantage of the ini way is that calibrate works :-)
[22:57:32] <Tom_itx> heh
[22:58:08] <Tom_itx> i'll get it working then move it over
[22:58:10] <pcw_home> you cal also just use halcmd to setp the P and I values live
[22:58:14] <Tom_itx> then tune it
[22:58:26] <pcw_home> can also
[22:58:30] <Tom_itx> yeah halcmd just won't save it
[22:58:39] <pcw_home> nope
[23:00:11] <pcw_home> I like halcmd from the terminal better than setp in the axis
[23:00:12] <pcw_home> show hal configuration window since you have command history
[23:03:26] <andypugh> Yes, halcmd -kf into an existing HAL session is a convenient wat to adjust stuff, and you get command history and tab-completion.
[23:03:50] <Tom_itx> can you put setp and net in the ini file?
[23:04:02] <Tom_itx> or do you address the vars differently there
[23:04:22] <pcw_home> nope
[23:04:33] <andypugh> The INI file is entirely passive. It is somewhere that other things can get data from
[23:05:22] <andypugh> HAL knows how to search the INI for [SECTION]PARAMETER to get numbers back.
[23:05:46] <Tom_itx> so PID-PGAIN = 10 would be used in the hal file as pid.0.Pgain = PID-PGAIN ?
[23:05:49] <Tom_itx> or such

[23:07:05] <andypugh> (Or [MARY]TARQUIN if you want)
[23:08:13] <Tom_itx> then using calibrate you just set the values of the ini vars and it will save them
[23:09:04] <andypugh> Well, you have to remember to pess the “save” buton
[23:10:52] <pcw_home> and you have to press 'test 'to use the values you enter
