[00:01:10] <MarcelineVQ> Not at all? Too narrow at the threaded end?
[00:01:26] <pink_vampire> i need it barb on each end
[00:03:07] <MarcelineVQ> Oh I meant for if you were gonna do lathe work anyway, not that this fits as-is
[00:03:38] <pink_vampire> yeah.. maybe
[00:04:05] <MarcelineVQ> Is your picture of two barbs then, one just has a single sort of ridge for a barb?
[00:04:59] <pink_vampire> but i almost never use the lathe, and if i find a reason to make a project i will jump on the opportunity
[00:05:27] <pink_vampire> MarcelineVQ: it's a lip like the radiator have
[00:19:02] <XXCoder> cool :)

[01:57:02] <pink_vampire> brass VS power hacksaw
[01:57:10] <pink_vampire> brass win
[01:57:16] <miss0r> :o
[01:57:23] <miss0r> morning
[01:58:59] <pink_vampire> https://i.imgur.com - this is after half an hour
[01:59:40] <miss0r> wtf.. something is wrong there
[01:59:46] <miss0r> are all the teeth gone?
[02:00:03] <pink_vampire> no
[02:00:05] <MarcelineVQ> even with a backwards mounted blade it should be making progress :o
[02:00:22] <pink_vampire> brand new blade
[02:00:27] -!- c-log has quit [Ping timeout: 252 seconds]
[02:00:48] <miss0r> no down pressure
[02:00:49] <miss0r> `
[02:00:51] <miss0r> ?
[02:01:11] <miss0r> blade mounted in the wrong direction & this model lifts the blade on the return stroke?
[02:01:24] <pink_vampire> brass is a lubricant, and it is 32 tpi blade
[02:02:25] <miss0r> is it stuffing the teeth?
[02:04:18] <pink_vampire> oh yeah
[02:05:18] <miss0r> 32 tpi is somewhat fine.. but brass realy shouldn't pack up in there

[02:08:59] <trentster> Hey all, I am trying to get edge finding routines to work, I can auto probe Z without issue, but when I try run e.g. a hole center finding routine I just get an info popup in the interface and the machine does not move. Any pointers from you heavy hitters in the audience?
[02:10:36] -!- mk0 has joined #linuxcnc
[02:12:20] <miss0r> what does the info popup say?
[02:12:41] <trentster> miss0r: let me go to the workshop and grab a screenshot
[02:12:43] <trentster> 1 sec
[02:14:50] <trentster> miss0r: "Probe four times +x, -x, +y, -Y at feednorm. (i)
[02:16:44] <miss0r> Sounds like it is asking for a manual probe. Are you sure you have the setup done correctly?
[02:18:19] <trentster> miss0r: No, I am trying to use the auto probe touch plate as the probe going very slowly, the same way i do for Z height. (click one wire on the bit the other is on the plate.
[02:18:38] <trentster> I know a proper probe is the way to go, just thought it would be neat to have this option.
[02:19:06] <trentster> I know the touch off plate works cause I use it for Auto Z every day
[02:20:14] <miss0r> Indeed. Looking for some documentation here
[02:20:20] <trentster> This is the routine I found on the forums. https://pastebin.com

[02:21:24] <miss0r> trentster: And you are sure your macro is complete?
[02:21:33] <miss0r> I can suggest reading this: https://forum.linuxcnc.org
[02:22:03] -!- laminae_ has joined #linuxcnc
[02:22:55] <trentster> miss0r: thanks…reading now.
[02:27:54] <pink_vampire> done
[02:29:04] <pink_vampire> starrett 10 tpi did the trick https://i.imgur.com
[02:30:30] <miss0r> pink_vampire: Are you sure it is brass? :) I mean - we are talking about a material notorious for not packing up blades'n files
[02:31:39] <pink_vampire> the source is metal junk yard.. so
[02:32:21] <pink_vampire> it is very heavy for the size, and cut fast with the 10 tpi
[02:33:02] <miss0r> hmm. sounds somewhat strange
[02:34:09] <pink_vampire> it is power hacksaw, so "fast" is anyway not the correct word to describe it
[02:34:43] <miss0r> hehe yeah. :]
[02:41:09] <laminae_> whew, got all the optical limit and home switches working, input pullup touch sensor working, the final step is nao
[02:42:15] <laminae_> I would like to be able to use "home all" and just have it ignore the z axis, i'm reading the doc file and it says that is a-ok but i don't see the commands in the ini file that should corrspond to that
[02:44:47] <pink_vampire> is is cut on the lathe amazingly good

[03:53:35] <XXCoder> made the connection ring I see
[03:54:37] <gloops> brass is nice to turn
[03:54:40] <MarcelineVQ> gonna end with the thinnest part? :O
[03:54:55] <gloops> looks like you got the emco singing now pink_vampire
[03:55:45] <pink_vampire> singing ?
[03:57:32] <pink_vampire> https://i.imgur.com
[03:57:37] <pink_vampire> better picture
[03:57:52] <gloops> yeah, like running well, finely tuned etc

[04:05:52] <MarcelineVQ> :>
[04:07:19] <XXCoder> lol
[04:09:57] <pink_vampire> now i need to do the tapered hole O_o
[04:10:18] <XXCoder> feeding at 2 axis at once
[04:10:21] <XXCoder> you can do it
[04:10:58] <pink_vampire> mmmm no
[04:11:04] <gloops> got rotating top slide by the look of it
[04:11:16] <pink_vampire> i'm going to set the compound
[04:15:57] <gloops> ive got some tapered reamers which make life a bit easier if trying to get a fit for morse tapers or whatever
[04:18:10] -!- gimps has quit [Ping timeout: 272 seconds]

[04:36:00] <gloops> well, still having erratic problems with a motor, it starts slow, eventually kicks in and jumps to full speed/power, when its warm it works fine
[04:36:15] <gloops> sometimes turns wrong way
[04:38:03] <pink_vampire> in the cnc?
[04:38:09] <gloops> think ill strip it today and do some cleaning, check the bearings
[04:38:17] <gloops> nah its for a bandsaw
[04:38:43] <pink_vampire> i have power hacksaw
[04:38:56] <pink_vampire> I'm sure you can cut much faster
[04:39:37] <gloops> well its only for wood, i have got a bandsaw that cuts steel, usually a bit quieter than hacksaw too
[04:40:09] <gloops> but hand feed lol
[04:41:20] -!- mk0 has joined #linuxcnc
[04:42:20] <pink_vampire> one day...
[04:43:24] <gloops> space really, have to decide what warrants a place
[04:45:43] <Loetmichel> *GNAAAAAAAAAHH!!!1111* coworkers worked on some thin clients for two weeks now... enclosures taped, powder coated, cables and plugs screwed in, PCBs for PSUs and monitor mounted... now the thin client board should go in... "why is that 5mm to big?" ... customer wants a new model client thats mini-itx instead of 160*100mm. WAAAAHHHH... and nobody told me or anyone down here in the manufacturing
[04:45:43] <Loetmichel> level. So we have to rip out all the stuff we have already done order the other enclosure design with bigger back caps (already did them for a different customer)... "redo from start"... and the delivery deadline is still ticking down... :-(

[04:57:17] <gloops> better with a product range lol, this is what we sell, if it aint there we dont do it
[04:59:11] <pink_vampire> almost done with the taper https://i.imgur.com
[05:00:20] <Loetmichel> gloops: we DO sell that other client.
[05:00:44] <MarcelineVQ> yellow brass sure is pretty
[05:00:48] <Loetmichel> but to a different customer. i was told to "do 20 clients for customer X like the last batch"
[05:01:01] <Loetmichel> nobody told me that they switched to a different client.
[05:01:06] <MarcelineVQ> or bronze, or whatever, as if I could tell hehe
[05:01:31] <pink_vampire> bronze is red almost like copper
[05:01:39] <gloops> i looked at melting brass, it is doable with a diy kiln
[05:01:53] <gloops> not done any quantity though, just a few small blobs
[05:02:28] <pink_vampire> i will save the shavings for you
[05:02:53] <gloops> lol, proper kiln is something for another day..or year
[05:03:00] <Blumax> Hello, is it possible to change defaults jog speed to start? I would like this to be 100% of the beginning.
[05:03:10] <pink_vampire> I have map torch
[05:03:22] <gloops> theres scrap brass everywhere in totally useless shapes
[05:03:34] <gloops> but brass bar or plate is a stupid price
[05:03:52] <pink_vampire> 5$ per lbs
[05:04:19] <gloops> Blumax i *think* default jog speed is the max velocity
[05:05:19] -!- JesusAlos has joined #linuxcnc
[05:05:29] <MarcelineVQ> bronze can be as yellow as your piece there, and brass can be as red as clay, just depends on the mix :O Kinda curious about the flow-rate you're going to get with this adapter, lets us know how it works out
[05:06:05] <MarcelineVQ> Is the flow from 3/8 to 1" or 1" to 3/8" ?
[05:06:42] <pink_vampire> I need to stop each time and walk to the computer, I wish it was voice
[05:06:56] <Blumax> gloops, good :) DEFAULT_LINEAR_VELOCITY, I search "job speed" ... bad way :( Thank you gloops :)
[05:07:09] <pink_vampire> it is a reducer for my radiator
[05:07:17] <pink_vampire> from 1" to 3/8"
[05:08:38] <gloops> thats also the speed the rapids move at Blumax, i had some playing with mine because the gantry jacknifes at a certain speed, it always did it during rapids until i reduced max velocity
[05:09:27] <Blumax> Ok, I take note :)
[05:15:56] <XXCoder> pink_vampire: shaping up nicely
[05:16:05] <XXCoder> I guess rotated umm cross thingy?
[05:16:10] <XXCoder> not sure what its called

[05:23:23] <pink_vampire> compound
[05:24:16] <pink_vampire> one side is done
[05:25:04] <pink_vampire> https://i.imgur.com
[05:28:13] <XXCoder> awesom now to make second one
[05:28:16] <XXCoder> and maybe third
[05:28:40] <gloops> whats it for?
[05:28:55] <pink_vampire> i need to make the other side
[05:29:12] <XXCoder> yeah though its easier to run few of em on side A first
[05:29:16] <XXCoder> then all of em on B
[05:29:21] <XXCoder> less setup time
[05:30:03] <pink_vampire> I know it is going to sound funny but I don't have holder for parting tool
[05:31:41] -!- merkatorix has quit [Read error: Connection reset by peer]
[05:33:50] <pink_vampire> it is tricky to hold
[05:34:35] <XXCoder> you could make inverse cone
[05:34:43] <XXCoder> use super glue glue it in it
[05:34:56] <XXCoder> then use torch to pop it off after making it complete
[05:35:37] <pink_vampire> to complicated
[05:36:13] <XXCoder> not really just grab a scrap alum rod, cut a cone that will nicely hold you part on it
[05:37:13] <pink_vampire> https://i.imgur.com
[05:38:13] <XXCoder> yeah would work I think? dunno

[05:52:20] <gloops> might pay to make some soft covers for chuck jaws some time, from ally or whatever
[05:53:38] <XXCoder> yo
[05:53:46] <MarcelineVQ> gloops: they also look nice, it's like sweaters for your chuck
[06:03:54] -!- P1ersson has joined #linuxcnc
[06:08:34] <gloops> yeah should have a set really
[06:15:52] <pink_vampire> scrap
[06:15:57] <pink_vampire> i killed it
[06:16:13] <XXCoder> doh what happened
[06:16:30] <MarcelineVQ> busted cutting the thin end?
[06:17:47] <pink_vampire> just got mesmerised by the large chips and go 21mm instead of 17mm
[06:18:04] -!- P1ersson has quit [Ping timeout: 264 seconds]
[06:18:21] <MarcelineVQ> ah, well, now you can practice brazing :D
[06:19:02] <MarcelineVQ> $90 in brazing supplies later... "nah, I'll just cut a new one"
[06:20:01] <pink_vampire> i will try finish it
[06:20:11] <pink_vampire> just for practice
[06:20:37] <pink_vampire> BTW this is my first mistake on the lathe
[06:21:25] <MarcelineVQ> Most people's first mistake involves crashing sounds and things in the air that don't belong in the air, so you're doing better than average
[06:22:07] <pink_vampire> the cut is fine, is just 4 mm deeper
[06:22:55] <MarcelineVQ> is that 8 off the dia or 4 off the dia?
[06:23:16] <pink_vampire> 8 off from the side
[06:23:30] <pink_vampire> 4**
[06:24:23] <MarcelineVQ> 4 off the radius? so it's now 8mm small overall?
[06:25:03] <MarcelineVQ> Just wondering because if it's just 4 overall you can probably get away with a hose clamp and still use it
[06:25:20] <pink_vampire> the part that the hose clamp hug is 17mm instead of 21mm, the part become shorter
[06:25:59] <MarcelineVQ> oh the length is 4mm short ok
[06:26:08] <gloops> at least youve still got all your fingers and both eyes
[06:26:36] <pink_vampire> lol yeah
[06:27:52] <pink_vampire> I need a cnc lathe
[06:29:47] <gloops> still plenty of scrap to be made with one of those lol
[06:31:37] <pink_vampire> https://imgur.com
[06:33:43] <XXCoder> second one car disco lol
[06:33:51] <MarcelineVQ> what the fuck is that sludge coming out of the rad cap
[06:34:15] <XXCoder> oil and coolant
[06:34:22] <MarcelineVQ> It's like someone hid their pudding in there so the kids wouldn't get it
[06:35:31] <pink_vampire> my GF killed a car by adding the windshield fluid to the oil
[06:39:43] <XXCoder> jeez lol
[06:40:35] <XXCoder> some of those car with water in weird places im pretty sure are flood cars
[06:41:04] <XXCoder> insurance covered those so they get car nove it far away from flood site and resell it hiding the fact that car was in flood
[06:41:57] <pink_vampire> she didn't got anything
[06:44:03] <XXCoder> #17 more disco lol
[06:44:56] <gloops> looks like water leak internally, head gasket maybe
[06:45:12] <XXCoder> yeah though some of those water ones is impossible
[06:45:18] <XXCoder> so likely flood car
[06:45:29] <XXCoder> like from tires
[06:47:04] <XXCoder> #21 wow! dont look like never changed oil ever
[06:49:32] BitEvil is now known as SpeedEvil
[06:49:41] <MarcelineVQ> water in tires isn't that uncommon, if you always top up from a moist air tank, not as much as in that vid though haha. sometimes offroaders put water in the tires to lower the vehicle center of gravity, not that it helps too much with most tire sizes
[06:50:24] <MarcelineVQ> It's more of a thing you'd see in tractors and such, large tires can serve as ballasts when filled with water
[06:51:03] <gloops> father in law had head gasket go, which he changed against my advice, was funny at the time the engine just became a foam making machine, every hose you pulled off was just pumping gunk out
[06:52:35] <gloops> about 6 cans of oil and engine flush later he realised it was a bad move
[06:53:23] <XXCoder> lol
[06:56:17] -!- huibuuh has joined #linuxcnc
[07:03:50] <jthornton> tractors don't use water in the tires anymore... alcohol is used now
[07:03:56] -!- emsjessec has joined #linuxcnc
[07:06:50] <MarcelineVQ> Well you have a mix of some kind, don't want exploded tires. that used to be calcium chloride, I'd be inclined to use an antifreeze of some kind
[07:06:59] <XXCoder> jthornton: tire booze lol
[07:07:47] <jthornton> yea the calcium chloride was too corrosive and would eat the rims even through the tubes
[07:09:44] <huibuuh> Hey hou, can someone help me with buying a CNC? I'm not sure if I can use LinuxCNC with this one:
[07:09:45] <huibuuh> https://www.ebay.co.uk
[07:11:39] <jthornton> look for one without the mach crap controller
[07:12:19] <XXCoder> theres cheaper ones
[07:12:34] <XXCoder> even with crap controller you can throw away and build better
[07:12:48] <XXCoder> hmm those has encoders

[07:40:13] <XXCoder> steppers all have positional senses
[07:40:15] <XXCoder> sensor
[07:40:40] <XXCoder> so its bit more fancy, but you could still use em with some other hardware so you can use linuxcnc
[07:42:06] <huibuuh> so when I get that machine I have to buy something extra to run it with lunix cnc?
[07:42:18] <huibuuh> linux* lol
[07:43:14] <XXCoder> " Mach 3 software is simple and intelligent" LOL
[07:45:20] <XXCoder> it says emc2 supported so linuxcnc can run it I guess
[07:45:52] <Deejay> RIP emc2
[07:45:57] <huibuuh> cool, thank you
[07:46:04] <huibuuh> so LinuxCNC is emc2 compatible?
[07:46:15] <Deejay> linuxcnc is emc2 ;)
[07:46:21] <XXCoder> indeed
[07:46:28] <huibuuh> oh, lol
[07:46:37] <XXCoder> old name, changed by lawsuit of some kind
[07:47:00] <huibuuh> I was searching for "parallel" because I read LinuxCNC can't do USB because USB is shit in terms of real time
[07:47:11] <huibuuh> but was unsure if it would actually work
[07:47:41] <huibuuh> thanks XXCoder, looks like I'm soon gonna have a CNC :P

[07:50:20] <huibuuh> hmmmm, well then I wouldn't have to build a new PC, I think I'm gonna try and see if I need parallel
[07:57:53] <jthornton> to test your PC download the LiveCD and boot from it then test your latency
[07:58:37] <jthornton> wow Monique really needed to get to the nest box the door was only open an inch and she put her head under it and lifted it enough to get out and dashed over to the nest box
[07:59:36] <huibuuh> jthornton yeah will do that

[08:02:58] <gloops> if it runs mach3 it must use a PC - so should just be able to install linuxcnc instead
[08:03:12] <gloops> what you dont want is the ones with their own built in controller
[08:05:27] <jthornton> wow my pip package installs lol
[08:06:34] <XXCoder> hey jt how goes your linuxcnc-tools or whatever?
[08:07:17] <jthornton> I've been working on my new chicken pop door lol... it's working nice and opens and closes when it should
[08:08:25] <jthornton> wow that didn't take Monique long to lay that egg
[08:08:46] <XXCoder> probably in hurry
[08:09:11] <jthornton> I glad she didn't lay it from the roost
[08:16:56] <miss0r> You know that feeling, when you just want to do something with old computer hardware? :)
[08:17:58] <MarcelineVQ> like emulate gameboy on a 386
[08:18:35] <miss0r> Something like that.. :) I'm looking at a 286 I have stored away under my desk here. I think I will try to make it live
[08:20:36] <miss0r> ha... its a 386
[08:20:53] <miss0r> AM386 DX/DXL-40
[08:20:54] <miss0r> neat
[08:21:14] <jthornton> my VMC has a 386 with the math chip
[08:21:47] <miss0r> nice. You know my VMC has a computer alot slower than that ;P
[08:21:58] <miss0r> Sadlt, this 386 here does not have a co processor
[08:22:44] <miss0r> TO THE LAP! :P
[08:23:47] <miss0r> also, I found something quite cute! :D

[12:57:41] <fragalot> Hey
[13:00:08] -!- diverdude has joined #linuxcnc
[13:00:21] <diverdude> Anybody with some experience in linux and serial communication interested in earning some extra money by helping me getting communications up and working with this translation stage? https://www.thorlabs.com It needs to be able to home, move absolute and relative in 2 directions and give position. Should be on linux. Have manual describing protocol. 60USD/hr - price negotiable depending on hour estimate
[13:02:57] <fragalot> there appears to be zero documentation on the low level serial protocol
[13:03:20] -!- Inline has joined #linuxcnc
[13:03:24] <diverdude> fragalot: there is a 367 page document
[13:03:42] <fragalot> couldn't find that on the linked page :)
[13:04:06] <fragalot> got a link to that?
[13:04:11] <Rab> diverdude, will you retain ownership of any driver framework, or could it be contributed to LinuxCNC or otherwise made public?
[13:04:20] <diverdude> I think because you need to be logged in. I can give you the link
[13:04:40] <diverdude> Rab: Could be made public....i dont mind if its public
[13:04:49] <fragalot> does your boss mind? :P
[13:04:55] <diverdude> fragalot: im my boss :)
[13:05:00] <diverdude> fragalot: its for me hehe
[13:05:09] <diverdude> fragalot: bought the damn thing myself :D
[13:05:16] <fragalot> had to ask :)
[13:05:29] <Rab> diverdude, cool, I don't have time for the effort but I wish you luck.
[13:06:11] <diverdude> ofc
[13:07:04] -!- CubicleNate has joined #linuxcnc
[13:07:05] <diverdude> Rab: heh ok....i hope somebody can help out on this. I did manage to make it work once using libftdi...but then something happened (i must have upgraded something) and now its not working anymore
[13:07:28] <fragalot> ftdi was notorious for bricking "non-authentic" devices a while back
[13:07:45] <diverdude> The problem with these things is that all the companies only write windoze code :/ If you are a linux user there is no help to get
[13:08:34] <diverdude> fragalot: ok - so what does that mean?
[13:09:18] <fragalot> if you had an ftdi clone chip in the device you had, and you connected it to a windows computer using the driver from ftdi, it would brick your device instantly
[13:09:30] <Rab> Yeah, I have a stash of various serial and ethernet servo drives with Windows-only support, software being hefty payware or just unobtainable...back burner projects, where the protocol is documented.
[13:09:35] <diverdude> ok - brick means not working?
[13:09:46] <fragalot> diverdude: brick means destroy the device
[13:09:51] <diverdude> ohhhhhh
[13:09:55] <diverdude> thats bad
[13:10:14] <fragalot> https://www.zdnet.com
[13:10:21] <diverdude> but this is original ftdi i think....it was pretty expensive
[13:10:32] <diverdude> think i paid 1400 EUR or something for it
[13:10:34] <fragalot> yeah this bricking thing was ages ago :)
[13:10:34] <Rab> https://hackaday.com https://hackaday.com
[13:10:52] <fragalot> ha I didn't know it happened twice :)
[13:11:07] <Rab> diverdude, oh, the FTDI chipset is integrated into the controller?
[13:11:13] <diverdude> Rab: yes
[13:11:28] <Rab> Probably less likelyhood of fake...one would hope.
[13:11:47] <diverdude> i have tried it on windows already...it works fine
[13:12:04] <Rab> There were a few reports of fake chips making it into ordinarily reliable supply chains.
[13:12:24] <fragalot> Rab: yea that was fun :D
[13:12:30] <diverdude> but it does not work on linux :(
[13:12:34] <diverdude> it should
[13:12:41] <Rab> OK, that should rules out fake chip.
[13:12:42] <diverdude> but i dont know how to communicate with it
[13:13:51] <Rab> diverdude, does the controller act as a simple serial device, or does it use extended FTDI chipset functions?
[13:14:17] <diverdude> Rab: hmm i think it can do both actually
[13:14:31] <Rab> Some of those FTDI chips can do bitbanging or other stuff.
[13:15:10] <diverdude> hmm how can i share this PDF document
[13:16:09] <Rab> Have you tried recording simple movements with Windows USB snooping software?
[13:17:02] <Rab> diverdude, maybe Google Drive.
[13:18:04] <Rab> Or I guess Dropbox has a free account.

[13:26:11] -!- {HD} has joined #linuxcnc
[13:29:50] <Rab> diverdude, looks like it. You said you had this working before, how were you interacting with it? LinuxCNC with a translation layer, or some other control software?
[13:31:41] <Rab> It seems like you could test the controller just by sending bytes to the serial device, e.g. MGMSG_MOD_IDENTIFY.
[13:31:57] <diverdude> Using this library: https://gitlab.com
[13:32:19] <Rab> Oh, wow.
[13:32:30] <fragalot> job done :D
[13:32:42] -!- CaptHindsight has joined #linuxcnc
[13:34:13] <diverdude> but its not working for some reason....when i connect first time its working ok. Then i close connection....and then i cannot connect anymore - i cannot even manually jog...i have to completely take out power and then connect power again before its back alive
[13:34:59] <Rab> diverdude, this is all important information.
[13:35:23] -!- CNC_Brian has quit [Quit: Leaving]
[13:36:31] <Rab> Maybe it's something simple like new version pylibftdi not releasing the device properly?
[13:36:34] <fragalot> looks ike the library does not send an FTDI reset, like the one mentioned at the start page 28 of the serial manual
[13:36:42] <diverdude> Rab: i have tried connecting it to my raspberry pi 3b+ now. Its identified there and connected to /dev/ttyUSB0
[13:36:46] -!- gloops has quit [Ping timeout: 272 seconds]
[13:37:16] <diverdude> fragalot: i see - interesting....but so strange that it was working a few months ago
[13:37:47] <fragalot> diverdude: line 63, controller.py
[13:37:49] <fragalot> # skipping reset part since it looks like pylibftdi does it already
[13:37:56] <fragalot> perhaps pylibftdi updated and no longer does it
[13:37:58] <Rab> diverdude, I like the idea of avoiding libftdi entirely and just using pyserial or something, but since this person has done all the work it only makes sense to take advantage of it.
[13:38:57] <Rab> CaptHindsight, beep
[13:39:09] <CaptHindsight> honk honk
[13:39:36] <diverdude> Rab: yeah that was my thought as well....would be really nice to have just clean understandable low level serial communication since this ftdi stuff does not work properly
[13:39:52] <Rab> CaptHindsight, I was wondering about thermal dissipation of that powerSTEP01 thing...lemme find my query
[13:40:10] <diverdude> fragalot: do you know what needs to be changed in that library to make it work then?
[13:40:13] <CaptHindsight> Rab: they don't post any that I could fine
[13:40:46] <CaptHindsight> just the low on resistance ~10mOhms
[13:41:02] <Rab> CaptHindsight, seems a little weird. The package seems obviously designed to heatsink through the PCB footprint, strange that they don't have layout recs.
[13:41:22] <CaptHindsight> oh I saw the layout docs
[13:41:27] <CaptHindsight> very specific
[13:41:36] <fragalot> diverdude: I *think* line 63 should be this: self.fdll.ftdi_set_bitmode(byref(self.ctx), 0, BITMODE_RESET)
[13:41:51] <CaptHindsight> Rab: I think they are in the data sheet
[13:42:00] <fragalot> except self.fdll should be dev.ftdi_fn
[13:43:14] <Rab> CaptHindsight, I couldn't find anything in the datasheet. Of course there's a suggested footprint.
[13:43:20] <diverdude> fragalot: ok in which file?
[13:43:27] <fragalot> diverdude: controller.py
[13:43:55] <diverdude> ok, let me try
[13:45:03] <CaptHindsight> Rab: follow them and do not ask
[13:46:03] <Rab> CaptHindsight, yeah, but the footprint by itself won't dissipate any heat.
[13:46:06] <fragalot> diverdude: another example code seems to use this: dev.ftdi_fn.ftdi_set_bitmode(0, BITMODE_RESET) to reset the device to a known state
[13:46:19] <CaptHindsight> run the numbers, 10A, ~10mOhms, 80V max rms, not much resistance
[13:46:57] <Rab> I guess the obvious thing to do is copy the eval board layout.
[13:47:17] <CaptHindsight> Rab: I haven't looked at the pads vs the package, but 10A copper routes obviously on the outer layer do it

[13:48:58] <CaptHindsight> https://www.st.com yeah, look at the layout
[13:51:23] <Rab> Yeah, was looking at gerbers for the nucleo board...pretty similar
[13:52:01] <CaptHindsight> heat travels out the corner pads to a wide copper area, you could add a heat spreader there
[13:52:09] -!- diverdud_ has joined #linuxcnc
[13:53:31] <Rab> The nucleo shields apparently work fine stacked, it'd be interesting to know if active cooling is called for at some point.
[13:53:33] <fragalot> diverdud_: I don't dare ask: but.. did it work? :P
[13:53:34] <CaptHindsight> if they don't provide ant thermal number then you could use the eval board, measure temp vs power over time and see what to do to improve

[13:58:22] <diverdude> so i am instantiating that class to communicate with the device
[13:58:25] <diverdude> hence, when i added the line you suggested to line 63 of the controller class i am getting ´object has no attribute 'fdll’
[13:59:04] <fragalot> diverdude: yeah it would do, that's why I corrected myself to dev.ftdi_fn.ftdi_set_bitmode(0, BITMODE_RESET)

[14:10:08] <fragalot> I think there was a kernel issue with ftdi-sio
[14:10:13] <diverdude> fragalot: btw. its no longer connected to my raspberry pi - i moved it back over on my mint 19 machine
[14:11:20] <diverdude> fragalot: i see....that could very well be....because if my memory serves me correct (it often does not though) It worked on mint 18 and debian squeeze, but not when i installed mint 19
[14:11:47] <fragalot> I'd start looking there then rather than paying someone to program something that won't make it better :P
[14:11:50] <diverdude> fragalot: could that make sense?
[14:12:21] <diverdude> fragalot: but i guess if its raw serial commincation i will not have such issues right?
[14:12:22] <fragalot> it does
[14:12:28] <fragalot> I don't know
[14:12:43] <fragalot> it's still going through the ftdi chip...
[14:13:12] <diverdude> fragalot: do you know which kernel has issues with ftdi-sio ?
[14:13:30] <fragalot> No ideqa
[14:13:37] * fragalot stares blankly at that stray 'q'
[14:14:11] <Rab> diverdude, tried emailing the pyAPT author?
[14:14:30] <diverdude> fragalot: hahahaha....thats actually quite funny :D
[14:14:59] <diverdude> Rab: no i have not tried that
[14:15:09] <fragalot> it seems that when I press keys too fast after one another, it throws a random other one in
[14:15:31] <CaptHindsight> Rab: 16mOhm gate resistance at 10A is only 1.6W, not much heat to dissipate
[14:15:33] <diverdude> But i guess my plan of trying this out on raspbian OS instead might make sense....i hope it has an older kernel then
[14:15:48] <fragalot> D+E+A = DEQA and E+D+S = EDZS :/
[14:15:51] <diverdude> fragalot: you are too fast my main. gotta slow down :)
[14:15:55] <Rab> CaptHindsight, noted.
[14:15:57] <diverdude> main = man
[14:16:18] <Rab> fragalot, are you using a Thinkpad?
[14:16:37] <fragalot> Rab: no, dell inspiron 15 5000 series
[14:16:40] <Rab> ahh
[14:16:43] <fragalot> only a few months old
[14:17:27] <Rab> Heard a similar complaint from fellow Thinkpad user, apparently an issue with the keyboard controller on certain newer models. I type slowly so it doesn't affect me.
[14:17:28] <fragalot> CaptHindsight: we have different opinions on what is "not a lot of heat to disspate" :P they add up!
[14:17:42] <fragalot> Rab: could be that we've got the same controller
[14:17:52] <fragalot> they're all made in china by the same company in the end anyway these days
[14:17:56] <Rab> rite
[14:18:17] <{HD}> XXCoder: hey. Last night were we talking about interval or jitter?
[14:18:33] <CaptHindsight> Rab: if you put those right on the back of the stepper motor I'd get fancy with coupling those traces to the heatsink enclosure
[14:19:27] <fragalot> diverdude: supposedly you can replace the ftdi_sio kernel module with libftdi .. don't quote me on that, and don't ask me how.
[14:19:39] <diverdude> my mint 19 runs kernel 4.15.0-generic and my raspberry runs 4.14.71-v7+ So it could actually be that it works on my raspberry if fragalot is right about the ftdi-issue in some kernel version
[14:19:54] <CaptHindsight> fragalot: maybe :) , 200W from a 2 x 2cm package was pretty common for me
[14:20:07] <diverdude> fragalot: hmm ok....i already ran sudo-apt-get install libftdi1
[14:20:08] <fragalot> CaptHindsight: :D
[14:20:23] <diverdude> fragalot: did that a while ago

[14:22:39] <CaptHindsight> they went over all the number for convection, conduction and radiated heat transfer...

[14:23:56] <CaptHindsight> at the end of the session i asked them why they didn't just flood the enclosure with coolant...
[14:24:15] <diverdude> Rab: you said i could just send a serial command to it and get a response. What should I send to try that?
[14:24:21] <fragalot> CaptHindsight: because it would leak if it got shot?
[14:24:40] <CaptHindsight> they look surprised and puzzled, wrote the suggestion down and ended the session
[14:24:53] <fragalot> lol
[14:25:32] <gloops> there was no aircon in Rommels day
[14:25:43] <fragalot> we try to make our controllers so that no additional coolant is required whenever possible.. granted, we're only dealing with switching 480W of inductive loads at 10kHz or so
[14:26:55] <CaptHindsight> if tanks in WWII had computers in them the heat from the tubes would have kept the crew warm on cold nights
[14:27:00] <gloops> same with Montys crews, when it got too hot you just undid your top button
[14:28:02] <fragalot> CaptHindsight: if you could make it boil tea the brits would be all over that as a solution
[14:28:06] <CaptHindsight> fragalot: yeah, coolant leaks, fans get jammed with dust etc etc
[14:28:28] <fragalot> CaptHindsight: that and those solutions cost money, passive cooling without heatsinks doesn't :D
[14:29:00] <Rab> diverdude, maybe MGMSG_MOD_IDENTIFY on pp.39? 0x23 0x02 0x01 0x00 0x11 0x01
[14:29:21] <Rab> If successfull, I guess the light on the controller will flash.
[14:30:40] <diverdude> Rab: how can i quickly test that in a terminal?
[14:30:45] <Rab> Or maybe that's for a different controller (BSC103). You might have to play with the last two bytes.
[14:32:38] <Rab> diverdude, maybe small ser.write script?
[14:32:53] <diverdude> Rab: you mean using pyserial?
[14:32:58] <Rab> diverdude, yeah
[14:36:28] <diverdude> Rab: using baudrate 115200 right?

[14:41:46] <laminae_> Hey guys, i'm stocking up on endmills for aluminum, since my old machine was not nearly rigid enough i didn't waste money on good endmills, what are you go to endmils for aluminum? i'm looking for a few 1/4in flat downcut and 1/8 and the same in ball nose
[14:42:38] <diverdude> Rab: fragalot this is my small test script (python3) http://paste.ubuntu.com
[14:43:00] <diverdude> it just waits for something back but nothing comes
[14:44:24] <fragalot> I don't think it's supposed to
[14:44:34] <fragalot> typically an identify command makes a little LED blink on the driver
[14:44:46] <fragalot> but I haven't read the manual, so no idea :-)

[14:46:39] <CaptHindsight> ^^ the 2 and 3 flute
[14:48:07] <laminae_> Wow, those are much more affordable than i expected
[14:48:45] <Rab> diverdude, what fragalot said
[14:49:03] <fragalot> oh my god what are those sizes
[14:49:08] <fragalot> 29/64
[14:49:35] <fragalot> at what point do you go to the decimal system?
[14:49:39] <CaptHindsight> uhmerican sizes!
[14:50:18] <Rab> laminae_, I use this guy: https://www.ebay.com
[14:50:28] <diverdude> Rab: fragalot something is interesting though...when i send S.write(b'\x23\x02\x01\x00\x11\x01') it also hangs it up completely, just like when doing the ftdi with pyAPT
[14:51:06] <fragalot> what does dmesg say
[14:51:45] <fragalot> I'm thinking something messes up, and the device can't handle a partial message correctly
[14:52:36] <CaptHindsight> Made in the USA https://www.shars.com
[14:52:48] <diverdude> fragalot: nothing interesting in dmesg it seems
[14:53:01] <laminae_> How significant is the performance from uncoated to coated tiain, tin etc when cutting almunim?
[14:53:33] <fragalot> uncoated is preferable
[14:53:43] <fragalot> aluminium likes to stick to tiain
[14:53:50] <fragalot> (in my experience)
[14:54:05] <laminae_> Ah, i thought it was the opposite, good to know
[14:54:26] <diverdude> fragalot: this is whats in dmesg since i connected it: http://paste.ubuntu.com
[14:54:28] <CaptHindsight> laminae_: watch your feeds and speeds, too hot tends to make alu stick as well
[14:54:59] <fragalot> diverdude: could be that the ftdi_sio module is still handling it
[14:55:30] <fragalot> diverdude: try unloading that kernel module & try again
[14:55:42] <CaptHindsight> laminae_: https://www.moldmakingtechnology.com
[14:55:44] <diverdude> fragalot: ok, how is that done?
[14:56:05] <fragalot> diverdude: no idea. been 12 years since I've last deqalt with that stuff
[14:56:15] <fragalot> d e a l t >.<
[14:58:05] <laminae_> so, this says 2 or three flute which is what i read earlier, is it fair to assume that chip evacuation is better on a 2 flute vs a 3 flute?
[14:58:20] <laminae_> Assuming the same depth of cut
[14:58:25] <diverdude> ok... how are problems like this normally solved ? :( I feel totally clueless.... the only thing i can think of which will give me a solution is to get a windows machine to be an intermediate communicator - and run a webserver on that windows machine that can talk with the translator. I can then call the windows machine from my linux machine via http
[14:58:38] <diverdude> which would be an insane solution :/
[14:58:46] <diverdude> but seems only possible solution
[14:59:21] <diverdude> translator = ftdi device
[15:01:46] <CaptHindsight> fragalot: 64ths is usually the limit for fractions, we also use decimals as well as numbers and letters for drill sizes in addition to your mm only system :)
[15:01:49] <fragalot> diverdude: try sudo rmmod ftdi_sio (or something along those lines?)
[15:02:17] <fragalot> CaptHindsight: how do you live with yourselves? next you'll say that you use gauge sizes for sheet metal that have no relation to anything else
[15:02:20] <fragalot> or schedule for wall thickness
[15:02:35] <CaptHindsight> keeps things interesting
[15:02:47] <fragalot> unless if said walls are on square tubing, in which case it's inches again
[15:02:59] <CaptHindsight> just imagine how boring life would be with just mm or mm and decimals :)
[15:03:37] <CaptHindsight> and they don't teach this in engineering school
[15:03:44] <CaptHindsight> more on the job stuff

[15:05:18] <CaptHindsight> eleventy zillion ways to write something
[15:05:21] <fragalot> accounting is the LAST thing I want to do
[15:05:22] <fragalot> lol
[15:08:17] <CaptHindsight> why do we assign weights to leather? 2oz vs 5oz etc
[15:08:31] <CaptHindsight> or papers
[15:08:36] <fragalot> because the same thing is done to paper, but differently
[15:08:42] <CaptHindsight> 100lb paper stock
[15:08:57] <CaptHindsight> I don't want to pick up that sheet :)
[15:09:40] <CaptHindsight> AC cooling capacity in tons
[15:10:20] <fragalot> really?
[15:10:22] <CaptHindsight> I'd like 3 tons of electricity please
[15:10:29] <fragalot> here it's in BTU which is a unit I also do not understand
[15:10:52] <CaptHindsight> BTU's are fun
[15:11:07] <SpeedEvil> https://what-if.xkcd.com On three tons of electricity
[15:12:34] <CaptHindsight> 1 ton = 12,000 BTU's

[15:31:21] <SpeedEvil> dunno
[15:35:25] <Rab> CaptHindsight, paper weight is per ream of 500 sheets. Here's all about a ream: https://en.wikipedia.org

[17:51:31] <JT-Shop> should be MDI_COMMAND G53 G0 X0 Y0 Z0 or similar then you need a button connected to that, a PyVCP button is the easy way

[17:54:32] <{HD}> I don’t see where Tom_L sets up pyvcp.but
[17:55:49] <JT-Shop> I don't see a rapid to machine home in tom's file unless they subroutine does that
[17:56:04] <JT-Shop> he may have a physical button
[17:58:10] <{HD}> Oh man! Physical buttons would be sweet!
[17:58:42] <JT-Shop> best to start simple then work up to complex, if you have a spare input that is easy as well

[18:00:59] <andypugh> halcmd setp halui.mdi−command−00 0
[18:01:07] <JT-Shop> you just need one input for a rapid to home unless you want more like rapid to Z0 then XY0 that needs a subroutine
[18:01:09] <andypugh> To toggle the mdi-command pin

[18:03:58] <Tom_itx> i may have forgotten to post the subroutine there
[18:07:45] <Tom_itx> mine is set up to go to work zero, not machine zero but the idea is the same

[18:10:54] <Tom_itx> part of it is

[18:11:23] <Tom_itx> and the main .ini
[18:11:56] <Tom_itx> [HALUI]

[18:11:56] <Tom_itx> MDI_COMMAND = G10 L20 P1 X0
[18:11:56] <Tom_itx> MDI_COMMAND = G10 L20 P1 Y0
[18:11:56] <Tom_itx> MDI_COMMAND = G10 L20 P1 Z0
[18:12:35] <Tom_itx> those are for setting the offsets
[18:12:52] <Tom_itx> the sub is to send it to the zero work offset
[18:13:40] <Tom_itx> change the sub to some other Gcode of your choice if you want to
[18:14:55] <{HD}> Whats the difference between sub endsub and call?
[18:16:29] <Tom_itx> sub and endsub define the boundaries of the subroutine as you see in work_zero.ngc
[18:16:39] <Tom_itx> call is used in the main code to call it
[18:16:55] <{HD}> https://i.imgur.com
[18:17:02] <Tom_itx> the filename and 'o' word need to be the same
[18:17:30] <skunkworks> o not 0
[18:17:45] <Tom_itx> that doesn't quite look right to me HD
[18:17:53] <Tom_itx> skunkworks your opinion?
[18:18:09] <Tom_itx> the MDI_COMMAND are for single line commands
[18:18:18] <Tom_itx> you would define the sub in a separate .ngc file
[18:18:34] <skunkworks> right - not like toms - you need a ngc file with the first one

[18:32:39] <jthornton> make a copy and bring it inside then post them?
[18:34:07] <jthornton> for a physical button it's two lines added to the configuration, the halui and the hal
[18:34:26] <{HD}> jthornton: let me go through these help docs and see if I can find it.
[18:34:52] <jthornton> are you going to do a PyVCP button to start with?
[18:35:28] <jthornton> http://linuxcnc.org
[18:35:33] <jthornton> there is your example!
[18:35:53] <jthornton> I thought I did an example of that
[18:36:15] <Tom_itx> that's just too easy :)
[18:36:37] <jthornton> I like easy
[18:36:49] <{HD}> Let me click it

[18:38:00] * jthornton wanders back to the chicken yard
[18:38:10] <Tom_itx> did you get your door fixed?
[18:38:23] <{HD}> Haha
[18:38:29] <jthornton> fixed? it was never broken...
[18:38:45] <Tom_itx> well you were working on something...
[18:39:55] <Tom_itx> you got a gear motor for something recently..
[18:40:04] <{HD}> Those examples are not in the OSes docs

[18:40:45] <Tom_itx> you pay for and get top tier support here :D
[18:42:45] <{HD}> 👍
[18:47:41] <{HD}> In the postgui.hal is it .mdi-command-00 because its the first in the list?
[18:49:09] <jthornton> yes, and what docs are you referring to?
[18:49:39] <jthornton> Tom_itx: yes I'm building a new chicken pop door for the shed and it's working very nice
[18:50:22] <jthornton> I got the other gear motor today along with the lock as well
[18:51:49] <{HD}> https://i.imgur.com
[18:52:59] <jthornton> looks right to me where did you put the subroutine file?
[18:53:01] <{HD}> I am getting air “custom_postgui.hal:6: Pin ‘ Halui.mdi-command-00’ does not exist
[18:53:13] <{HD}> S/air/error
[18:53:33] <{HD}> The .ngc is save in my configs file
[18:53:37] <{HD}> Folder*
[18:54:26] <jthornton> the .ngc file must be in either the nc_files directory or a directory on the search path which I assume you have not configured yet
[18:54:42] <jthornton> you also have to restart LinuxCNC after adding a subroutine file
[18:55:06] <jthornton> and after making any changes to the configuration
[18:55:39] <{HD}> jthornton: like reboot the computer? I will move the .ngc to nc_files
[18:55:53] <jthornton> no, just restart LinuxCNC
[18:56:59] <jthornton> also did you add the .xml file to the display section?
[18:58:10] <{HD}> Yes display.xml is added to the [display] section
[18:59:52] <{HD}> Arg! I am going to go grab a usb drive.
[19:00:02] <jthornton> why?
[19:05:48] -!- gectorw has joined #linuxcnc
[19:06:22] <{HD}> https://github.com
[19:06:32] <{HD}> Still getting some error
[19:07:04] <jthornton> what error?
[19:08:12] <{HD}> The same one I quoted earlier ^
[19:08:24] <{HD}> Pin doesn’t exist
[19:09:51] <jthornton> comment out that line then run your configuration and in axis show hal configuration to see the pin names
[19:11:25] <jthornton> I don't have a parallel port on this pc so I can't run the configuration
[19:11:38] <{HD}> https://i.imgur.com this?
[19:12:13] <jthornton> yes you can check for spelling errors by viewing the pins
[19:12:30] <jthornton> hmm I don't see halui
[19:13:14] <{HD}> [HALUI] is under [HAL] in the .ini
[19:13:37] <{HD}> I have comments near it
[19:14:05] <jthornton> no your missing HALUI = halui in the [HAL] section
[19:14:27] <jthornton> http://linuxcnc.org
[19:14:42] <jthornton> so my example is missing a step I see :(
[19:15:18] * jthornton goes to lock up the chickens for the night and call it a night
[19:17:03] <{HD}> jthornton: it works!
[19:18:57] <jthornton> yippie! now the sky is the limit
[19:19:04] <jthornton> see you later

[19:31:25] <jthornton> interesting a portable bandsaw with a vise
[19:32:22] <andypugh> You can unbolt from the base for hand-held use
[19:33:17] <andypugh> I saw it on eBay for £220 and was about to buy one (payday tomorrow, and the account looks healthy) but did a quick web search…. Glad I did.
[19:33:46] <SpeedEvil> I am unsure I don't have enough saws.
[19:33:47] <SpeedEvil> :)
[19:34:02] <andypugh> No more: https://photos.app.goo.gl
[19:34:46] <SpeedEvil> https://www.amazon.co.uk just got on ebay, which is a fucking odd device.
[19:34:50] <SpeedEvil> Seems to work OK though
[19:35:39] <SpeedEvil> It is not a fine woodworking tool, but it was bought to a large degree to be cutting up stuff to dispose of.
[19:36:40] <andypugh> The Evolution saws seem pretty good from what I have seen.
[19:37:14] <SpeedEvil> Indeed.
[19:40:10] <skunkworks> andypugh: that portable bandsaw has the capacity you need?
[19:40:31] <andypugh> 127mm. Yes, should do most of what I need.

[20:34:24] <andypugh> I _think_ that if you exit the app and then wait long enough before shutting down it won’t re-open.
[20:34:44] <andypugh> It bugs me too that apps I close before shutting down re-open automatically.
[20:36:07] <CaptHindsight> thats why distros should take votes for every feature...

[21:46:34] <SpeedEvil> https://www.motorsport.com fun
[21:47:04] <SpeedEvil> Blender is ideal for designing machines that might need to grow fur at some point.
[21:52:54] <{HD}> SpeedEvil: I have played with blender but never took the time to fully learn it. I made my coffee and sprinkle donuts and moved on.
[21:55:49] <SpeedEvil> Indeed - it's largely orthogonal to actual 3d modeling of machines you might want to construct at many points.
[21:56:11] <SpeedEvil> Or at least has so many features that you will never want to use that it's spammy.

[22:15:04] <roycroft> i picked up a nice 600mm starrett square blade today
[22:15:21] <roycroft> it has a satin finish, but it's pretty well-worn, and is getting rather shiny in places
[22:15:41] <roycroft> i'd like to restore the satin finish at least somewhat
[22:15:48] <roycroft> any suggestions on a good way to do that?
[22:17:43] <Tom_itx> 3m pad maybe?
[22:17:55] <roycroft> that would probably just make it shinier, i should think
[22:18:09] <roycroft> it would make the finish more even but in the wrong direction
[22:18:11] <Tom_itx> 2500 or more grit paper
[22:18:21] <roycroft> that would make it very shiny
[22:18:37] <roycroft> blasting with find aluminium oxide is more what i'm thinking
[22:18:41] <Tom_itx> sand blast it :)
[22:18:58] <roycroft> i just need to protect the paint in the engravings
[22:19:04] <Tom_itx> why the need to change the way it looks?
[22:19:14] <roycroft> because it's hard to read when it's shiny
[22:19:24] <roycroft> that's why starrett offered a satin chrome finish in the ifrst place
[22:19:40] <roycroft> it's a purely functional thing
[22:19:51] <roycroft> and if i might make it worse i'd rather do nothing

[22:42:55] <{HD}> Rub paraffin into engraving sand blast it the. Melt out the wax
[22:45:38] <roycroft> i was considering some kind of filler for the engraving
[22:45:48] <{HD}> Or Polyethylene+paraffin wax.
[22:45:49] <roycroft> paraffin might work great for that
[22:46:13] <{HD}> I think they call it “machinists wax”
[22:46:27] <roycroft> i should probably take some scrap steel and practise the technique on that
[22:46:52] <roycroft> some of my other rules are starting to get a wee bit shiny
[22:46:53] <{HD}> Or maybe “machining wax” I don’t remember
[22:46:57] <roycroft> i've had some of them for decades
[22:46:59] <roycroft> and they do get used a lot

[22:49:13] <roycroft> i have some sealing wax, which horologists use to fill the engraving on clock faces
[22:49:16] <Tom_itx> https://www.ebay.com
[22:50:07] <{HD}> I wonder what the makeup of sealing wax is.
[22:50:16] <roycroft> i don't know
[22:50:21] <roycroft> but it gets pretty hard and brittle
[22:51:06] <Tom_itx> The proportion of chalk varied; coarser grades are used to seal wine bottles and fruit preserves, finer grades for documents. In some situations, such as large seals on public documents, beeswax was used. On occasion, sealing wax has historically been perfumed by ambergris, musk and other scents.
[22:51:16] <{HD}> Tom_itx: looks good but that would require a bit of extra work to get that to communicate with the computer.
[22:51:29] <{HD}> Unless like a arduino would be good wnough
[22:51:42] <Tom_itx> are you using a mesa card?
[22:51:51] <Tom_itx> direct interface if you are
[22:52:02] <roycroft> i doubt ambergris is used any more
