12:04 AM toastyde1th is now known as toastydeath
06:08 AM jthornton: which hot end are you getting?
06:09 AM XXCoder: e3d clone. better clone than one that come with ours
06:09 AM XXCoder: one that has actual conpitable parts
07:00 AM XXCoder: jthornton: did you see linuxcnc mascot I modified?
07:00 AM jthornton: no
07:00 AM XXCoder: lemme get link
07:01 AM XXCoder: https://forum.linuxcnc.org/show-your-stuff/32672-linuxcnc-logo?limitstart=0#92394
07:01 AM XXCoder: its all vector so we finally can have big mascot pictures
07:03 AM jthornton: cool
07:03 AM XXCoder: so what ya think
07:04 AM jthornton: I like the blue one :)
07:05 AM XXCoder: yeah most of work is by other guy

07:23 AM XXCoder: I wonder if the mascot logo will be final one
07:49 AM gcardinal: awesome to see new logs - no offence to anyone - but their are not cleanly done
07:49 AM gcardinal: so would be challenging to mill them out since there is too many vectors
07:53 AM * gcardinal will contribute

09:03 AM IchGucksLive: someone recently seen our pik panthere who milles tiny part on maximized mashines
09:28 AM IchGucksLive: till later
09:52 AM Loetmichel_: JT-Shop_ as long as he doesent uses it in a VM then... on a notebook...
09:52 AM Loetmichel_: :-)
10:08 AM * jym hands {HD} 2 gallons of gasoline, a road flare, and a bag of marshmellows
10:14 AM {HD}: gasoline roasted marshmellows...ick!
10:19 AM Loetmichel_: the gasoline isnt for the marshmellows... its for you ;I)
10:19 AM Loetmichel_: the matrshmellows are for the spectators ;)
10:29 AM enleth: finally got the KUKA KR200 delivered to a warehouse, so it has somewhere to stay until the shop move
11:32 AM MacGalempsy: yo
11:50 AM MacGalempsy: its been some time since I was on this machine
11:50 AM MacGalempsy: really need to figure out how to get a new mb fan to make this thing quite again
11:58 AM MacGalempsy: wolffff
12:22 PM IchGucksLive: hi
12:23 PM MacGalempsy: hi
12:23 PM IchGucksLive: Loetmichel_: did you get in trouble on the wether front
12:25 PM Loetmichel_: a bit
12:25 PM Loetmichel_: <- wet ass
12:26 PM IchGucksLive: still dry here less then 2 liters
12:26 PM MacGalempsy: we had 6.5 inches within 24hrs
12:26 PM Loetmichel_: (the BMW seems to have a bit of a "too less water block" on the soft top... it rains thru the canvas :-(
12:28 PM Loetmichel_: need to get it dry, then sew in the new rear window and then spill a ton of sot top sealant on it ;)
12:29 PM IchGucksLive: il only got mercedes after crashing the VW long time ago as i wars 18
12:29 PM Loetmichel_: <- bought a "new" car two weeks ago...
12:30 PM Loetmichel_: http://www.cyrom.org/palbum/main.php?g2_itemId=16577&g2_imageViewsIndex=1 <- and the day i got license plates on it it starts to rain without end :-(
12:30 PM MacGalempsy: i am still looking for another car
12:31 PM MacGalempsy: I would like to get a Toyota Prado
12:31 PM Loetmichel_: rear window needs some work, got the new window yesterday, and the sewing kit for it today... now for a dry week... or i should clean out my garage to put it in there to dry up...
12:54 PM roycroft: i am happy with my prius, now that it has a new engine
12:57 PM IchGucksLive: roycroft: it is always as it is
12:58 PM IchGucksLive: eighter one or the other way
01:06 PM Loetmichel_: roycroft: my wife gets a new Mercedes GLC hybrid in august.
01:06 PM Loetmichel_: i'll think that will be nice. considering it has a 211HP petrol engine AND a 116HP electric motor...
01:06 PM Loetmichel_: only 50km pure electical range tho
01:09 PM IchGucksLive: tesla 3 in 2018 will have 600km one charge
01:09 PM IchGucksLive: mask promisses
01:11 PM Loetmichel_: IchGucksLive: still to short.
01:11 PM Loetmichel_: if you consider it takes about 8 hours to recharge it
01:12 PM IchGucksLive: 97% of all people do not drive 600km a day
01:12 PM Loetmichel_: (even on a supercahrger its 2 hours)
01:12 PM Loetmichel_: no
01:12 PM IchGucksLive: even 80% stay below 200km a day
01:12 PM Loetmichel_: nearly ALL people drive that far.but only about once a year or even less often
01:13 PM Loetmichel_: so its not a case of "IF" its a case of "when" thats gonna bite your a**
01:13 PM IchGucksLive: germany got a goot transpostsystem to use
01:14 PM Loetmichel_: or you would need to rent a car for those cases. but thenn you can buy an (electric) car with 300km range for MUCH less than a tesla and be happy anyway
01:14 PM IchGucksLive: fully agrees
01:15 PM IchGucksLive: i managed to go 280km in 3 years
01:15 PM IchGucksLive: ok i did live in a cave
01:15 PM IchGucksLive: no time to go carride
01:15 PM IchGucksLive: :O
01:17 PM IchGucksLive: CNC concept wanted for 1m width and best stabitity without using gantry
01:17 PM IchGucksLive: someone got a good idee on SBR
01:17 PM IchGucksLive: HWIN is quite expencive
01:18 PM IchGucksLive: as it is 1,5m X length
01:19 PM IchGucksLive: are there cheep hwin in europ
01:32 PM IchGucksLive: im off Gn8
01:33 PM TurBoss: hello
01:47 PM Todd_Z: Loetmichel_: Wish my old e36 325i looked half as good as that 318. Rust has nearly killed mine.
01:48 PM Loetmichel_: Todd_Z: only a single coin sized surface rust plot on the whole car.
01:48 PM Loetmichel_: got REALLY lucky
01:49 PM Todd_Z: Not sure if I can safely use the jacking points anymore.
01:50 PM Loetmichel_: Todd_Z: the 316i i bought last year as a beater while my Omega was at the mechanic was that way
01:52 PM Loetmichel_: http://www.cyrom.org/palbum/main.php?g2_itemId=16289&g2_imageViewsIndex=1 <- had to put a 1by4 under the jacking point. on the first try without it the liftjack disappeared into the car without moving it a single mm ;)
01:54 PM Todd_Z: Mine's way worse, I'm talking about the jack holes on the sides are giving out.
01:54 PM Todd_Z: Unfortunately they use lots of salt on the roads every winter here.
01:55 PM Loetmichel_: thats the other side under the fender: http://www.cyrom.org/palbum/main.php?g2_itemId=16277
01:56 PM Loetmichel_: http://www.cyrom.org/palbum/main.php?g2_itemId=16280
01:56 PM Loetmichel_: ... fortunally i only paid 450 eur for it... and got 100 eur back when i finally sold it
01:57 PM Todd_Z: They don't call where I live the rust belt for nothing.
01:58 PM _methods_ is now known as _methods
01:58 PM Loetmichel_: the "new" one i bought two weeks ago has a few problems also, though... soft top is leaking EVERYwhere, needs a new rear window, it has a REALLY hard "threaded suspension" in it, the tyres are done for and some minor problems with the ASC and the automatic soft top drives
01:59 PM Loetmichel_: i already got rid of the aftermarket "el cheapo" angle eyes headlights and the darkened rear lights
02:00 PM Loetmichel_: ... they DO call that E36 series "oelaugen-karre" here in germany for a reason.
02:01 PM Loetmichel_: it seems 3/4 of E36.owners are from the middle east and have a particular bad taste in "tuning" these cars
02:02 PM Loetmichel_: ("oelaugen" means "oil eyes" and rides on the fact that most middle eastern guys (and gals) have dark brown or near black eyes)
02:03 PM Todd_Z: There aren't many e36s on the road any more arround here. Kids have killed most of em.
02:04 PM Loetmichel_: i can understand why
02:04 PM Loetmichel_: did a 720 today at the aotbahn exit...
02:05 PM Loetmichel_: rain...
02:05 PM Loetmichel_: and a non-functional anti slip control ;)
02:05 PM Loetmichel_: autobahn
02:05 PM Tom_itx: awesome
02:05 PM Tom_itx: you're still here to tell us about it
02:05 PM Loetmichel_: accidantally
02:06 PM Loetmichel_: Tom_itx: i drive the Opel omega now for about 8 years... which is also rwd and also light in the back
02:06 PM Todd_Z: My 92 pre dates ASC, and I've never spun it once.
02:06 PM Loetmichel_: i am pretty used to a rear axle slipping.
02:07 PM Tom_itx: i prefer rwd but don't own one currently
02:07 PM Loetmichel_: after the initial "oh shit" its easy to countersteer
02:07 PM Todd_Z: Now my Fiero on the otherhand I've had turned arround countless times.
02:07 PM Loetmichel_: i just wasnt expecting it to do it THAT easy, thats all
02:08 PM Tom_itx: years back we'd take the vw bug out just for that purpose
02:09 PM Loetmichel_: what i meant is that its pretty easy to kill yourself in that car, especially if its your first and you have no idea how to react if it loses grip
02:09 PM Loetmichel_: or kill the car at least
02:50 PM TurBoss: hello again
03:03 PM {HD}: rain = sleepy
03:21 PM McBird is now known as McBride36
03:25 PM {HD}: Well, I just ruined one of these drawer slides trying to 'better understand it'. Luckly I know now how to proceed. I just need to drill access holes where I need them...lol
03:27 PM jym: {HD}: Ummm... don't do that!
03:27 PM {HD}: dont make access holes?
03:28 PM {HD}: But I need to
03:28 PM CaptHindsight: {HD}: $5 at home depot
03:28 PM {HD}: CaptHindsight: For what?
03:28 PM {HD}: drawer slides?
03:28 PM CaptHindsight: yeah
03:28 PM jym: {HD}: Ummm... don't do that --> "ruin the drawer slides"
03:29 PM jym: {HD}: http://homedepot.com/holesforsale
03:29 PM CaptHindsight: I use them on drawers to make them slide
03:29 PM {HD}: jym: Oh, yea...I have a whole box that I found of these drawer slides...I think they came out of highcap horizontal file cabinets.
03:29 PM {HD}: holesforsale?
03:30 PM CaptHindsight: jym: do you drill holes in things to better understand them?
03:30 PM {HD}: CaptHindsight: lol, I don't see any on HD.com for $5
03:30 PM jym: {HD}: yep, you can get a case of holes really cheap
03:30 PM CaptHindsight: jym: or do you buy your holes?
03:30 PM {HD}: haha
03:31 PM jym: CaptHindsight: I prefer to use my torch as much as possible
03:32 PM CaptHindsight: drawer slides usually have too much play in them to be used for machining
03:32 PM CaptHindsight: but they are better than some machine designs I've seen
03:32 PM gregcnc: just fill the drawer with double the load rating of the slide, the play goes away
03:32 PM {HD}: They have tight enought tolerence to be attached to the boxes that hold my tools.
03:34 PM CaptHindsight: about every 6 months this video gets passed around as an example of not to build a machine https://www.youtube.com/watch?v=8PSG2al1Sus unless it's just for fun
03:35 PM {HD}: lol, holy shit!
03:36 PM {HD}: hahaha but WHY! Does videoer live in a place where only pipe and pipe fittings are available?
03:36 PM CaptHindsight: hopefully it was a learning experience
03:37 PM SpeedEvil: That ratehr depends what it's for
03:37 PM CaptHindsight: if all you have are lemons...
03:37 PM SpeedEvil: Is it going to do steel - well - no.
03:37 PM SpeedEvil: Might it carve surfboard blanks just fine, yes.
03:37 PM CaptHindsight: large whip cream figurines, go for it
03:37 PM {HD}: SpeedEvil: Not even...the wacky wobble was ultra visable.
03:37 PM {HD}: CaptHindsight: Yea, maybe
03:38 PM SpeedEvil: yeah - he needs bracing at least
03:38 PM CaptHindsight: jello patterns
03:38 PM CaptHindsight: butter tooling
03:38 PM CaptHindsight: melts away and is biodegradable
03:39 PM * {HD} hooks cow directly to CNC machine
03:52 PM CaptHindsight: went into a brand-spanking-new Buckeys (gas station) yesterday...
03:53 PM gregcnc: by my house
03:53 PM CaptHindsight: everything was automated and even the coffee makes had LCD touchscreens
03:53 PM CaptHindsight: gregcnc: yeah
03:54 PM CaptHindsight: the soda fountain must have 50 nozzles and is 20 ft long
03:55 PM {HD}: I don't think I have ever been 'inside' a gas station. Unless you count the 'malls' that are on the turnpike.
03:55 PM gregcnc: not a few of those magic machines?
03:56 PM CaptHindsight: this was more a convenience store than gas station, they even have tables to sit and eat at
03:56 PM gregcnc: it's big I haven't stopped there yet
03:57 PM CaptHindsight: 3 icee machines, soft serve, frozen yogurt, ....
03:57 PM CaptHindsight: was more like the inside of a Dairy queen or Sonic
03:57 PM gregcnc: that's where those places make their money, it's not gas, hasn't been for years
03:58 PM CaptHindsight: it was just shy of a scene from Idiocracy
03:58 PM gregcnc: only missing the massage parlor?
03:59 PM CaptHindsight: didn't notice, but I'm sure the ChinaCo versions have them
03:59 PM CaptHindsight: drive-thru even
04:00 PM CaptHindsight: didn't notice much in the way of clothing but they were still setting up
04:00 PM CaptHindsight: speaking of pre-ground steel plate....
04:02 PM CaptHindsight: gregcnc: do they stock locally? http://www.flatground.com/index.htm
04:03 PM CaptHindsight: I only see rod there
04:05 PM gregcnc: if you click a material it will list thickness option if available. I haven't tried them yet so not sure if they stock at that address
04:05 PM CaptHindsight: looking for 1/2" ~6" x 18"
04:07 PM CaptHindsight: http://www.diesupplies.com/ looks good
04:08 PM CaptHindsight: Indianapolis so a day by ground
04:21 PM Deejay: gn8
04:35 PM {HD}: Alternatively I could alter all of these drawer slides so the stop was connected to the drawer and not the slide itself...
05:35 PM MacGalempsy: boink
05:37 PM sync: quack
05:37 PM MacGalempsy: bing
05:37 PM Tom_itx: oink
05:37 PM MacGalempsy: slink
05:38 PM MacGalempsy: anyone making a mess today?
05:40 PM JT-Shop2: yea, got saw dust all over the new shop
05:42 PM MacGalempsy: sounds fun. this is the end of my first week off. about 2 more to go
05:42 PM JT-Shop2: making a chicken coop
05:42 PM Tom_itx: then chicken soup?
05:44 PM MacGalempsy: how many chickens?
05:45 PM MacGalempsy: we had a dozen and that was egg hell. like 10 eggs a day average
05:45 PM MacGalempsy: for 2 ppl
05:46 PM JT-Shop2: 6 chicks, 5 hens and 1 rooster
05:46 PM JT-Shop2: yea be giving away a bunch of eggs
05:55 PM insomnia: Instead of 1 rooster, you should say '1 cock'
06:01 PM phipli: We're down to only two after an upsetting 6 months (from 4)
06:01 PM phipli: but have two more arriving in a couple of weeks
06:02 PM JT-Shop2: his name is Coq au Vin
06:03 PM phipli: JT-Shop2, what do you do about introducing new chickens to the flock? it is a long time since I have
06:03 PM phipli: (I was a kid when I last had chickens)
06:03 PM JT-Shop2: my first adventure in chicken ranching :)
06:04 PM phipli: excellent
06:04 PM phipli: they make great pets
06:04 PM phipli: even if you didn't quite mean them to be!
06:04 PM JT-Shop2: http://gnipsel.com/images/chicks/coop02.jpg
06:04 PM JT-Shop2: http://gnipsel.com/images/chicks/chicken-run-1.jpg
06:04 PM phipli: Nice
06:04 PM JT-Shop2: the RRR'
06:04 PM JT-Shop2: s are the most friendly of the bunch
06:04 PM phipli: we have a commercial coop CNC'd from a big sheet of plastic
06:05 PM phipli: RRRs?
06:05 PM phipli: Rhode Island Reds?
06:05 PM phipli: that doesn't even fit
06:05 PM phipli: headdesk
06:06 PM MacGalempsy: yeah. those are my favorites too
06:06 PM JT-Shop2: I have 4 RRR's and 2 Barred Pylmth Rock
06:06 PM JT-Shop2: yea Rhode Island Reds
06:06 PM MacGalempsy: the brown sexlinks and americunas were the wildest bunches
06:06 PM phipli: We have some some Rhode Island / white sussex crosses
06:08 PM phipli: soon to gain a speckledy and a blue ranger
06:09 PM MacGalempsy: we still have ours setup, but the wife said she wouldnt take care of anymore animals while Im working on the rigs
06:11 PM phipli: :(
06:11 PM phipli: could bring one with you?
06:11 PM phipli: egg for breakfast...
06:11 PM phipli: no chance of foxes
06:16 PM JT-Shop: I'm just glad my buddy likes chickens and will take care of them when we ride Texas in June
06:21 PM MacGalempsy: how is the drone coming along?
06:21 PM MacGalempsy: the tweaker?
06:21 PM JT-Shop: burned out an esc on the tweaker, the Q100 I just got it configured almost
06:22 PM JT-Shop: I have a new set of esc's for the tweaker but chicken coop building is keeping me busy lol
06:25 PM JT-Shop: http://gnipsel.com/images/chicks/coop03.jpg
06:30 PM JT-Shop: the VTX on the Q100 works :)
07:24 PM LeelooMinai: Hmm, I got nice anti-vibration pads for my machine - cork sanswiched between hard rubber, but putting them under the stand will not be easy.
07:26 PM LeelooMinai: I ordered this, and plan to lift the whole stand + cnc, but not yet sure if this is a sane idea: https://www.homedepot.ca/en/home/p.6-ton-bottle-jack.1000791797.html
07:26 PM Loetmichel: no pallet forklift?
07:27 PM LeelooMinai: Not really, it's a household not a company.
07:27 PM Loetmichel: got a massive friend, some two by fours and a bit of trust in him?
07:27 PM MacGalempsy: how big is the machine?
07:28 PM LeelooMinai: No, only 65 yo mom
07:29 PM LeelooMinai: Not very big, but still, cannot do it "by hand" - I don't know how much it weights - maybe 100kg with the stand?
07:30 PM Loetmichel: hmmm
07:30 PM Loetmichel: and no big guy in the neighborhood that could lend you a hand?
07:30 PM Loetmichel: 100kg isnt THAT much
07:30 PM MacGalempsy: time to start pumping iron
07:31 PM LeelooMinai: I mean that bottle jack thing will have no problem with lifting it, but I am worying it will just float to the side.
07:31 PM MacGalempsy: nah, that is small enough to get 2 men on that
07:31 PM Loetmichel: big guy tilts the machine and you shove the pads under it on one side, then tilting the other way: other two pads
07:31 PM Loetmichel: done in 5 minutes
07:31 PM LeelooMinai: If it topples over it will have dire consequences...
07:32 PM Loetmichel: if it topples over the big guy wasnt big enough
07:32 PM Loetmichel: i am not particulary big but i can lift a machine of that class with the stand alone
07:32 PM Loetmichel: and on all 4 legs, not just tip it a bit
07:33 PM Loetmichel: s/alone/without help
07:33 PM LeelooMinai: Well, not sure how that would work - you could break the spine.
07:33 PM Loetmichel: dont think so
07:34 PM Loetmichel: i am 125kg myself... lifting relatively compact 100kg isnt that much of a problebm if you know how
07:35 PM LeelooMinai: Maybe 100kg in a form for lifting, ok, but here it would be rather awkward - as the machine is tall, there's not easy way to lift it really.
07:35 PM Loetmichel: i used to work for a stage rental company... one speaker was about 100kg... and a LOT less compact... we stacked them into 3 rows high racks... by hand. one person. regulary
07:36 PM roycroft: i can lift 10k by myself :)
07:36 PM roycroft: 10kg
07:36 PM LeelooMinai: Maybe worth considering the strongmen competition...
07:36 PM Loetmichel: strongmen is another league
07:37 PM Loetmichel: they deal with 300++ kg weights... no thanks
07:37 PM roycroft: i'm in the process of painting my lathe stand right now
07:37 PM roycroft: it weighs about 80kg
07:37 PM roycroft: just moving it around and flipping it upside down and back up is pushing my limits
07:37 PM Loetmichel: hrhr
07:37 PM roycroft: but i shall persevere
07:38 PM roycroft: mayhap if i neglected to put on the respirator when spraying it i would not feel the pain of moving it so much
07:38 PM Loetmichel: i DO have some funny moments at my new company... which makes military computers and is made entirely of "office weaklings".
07:38 PM Loetmichel: ... especially when new deliverys arrive or have to go out
07:39 PM Loetmichel: because we have no forklift.
07:39 PM roycroft: but you have loetlift!
07:39 PM LeelooMinai: I am just sitting to linuxcnc and have my encoder attached to the X stepper. Planning to test what I can safely do in terms of motion speeds.
07:40 PM Loetmichel: got some strange looks when i unloaded a spool of wire from the DHL truck lately.
07:40 PM Loetmichel: looked at the 1/2 eur pallet. ... grabbed it, lifted it out of the van and carried it inside...
07:40 PM Loetmichel: the dhl driver looked like he saw a ghost...
07:41 PM Loetmichel: i commented: "WHAT? this palled says its only 94kg..."
07:41 PM Loetmichel: -d+t
07:42 PM LeelooMinai: I watched something on youtube once where they made a "gag" with small girl lifting a stack of concrete tiles that were really made from some foam - was pretty funny.
07:42 PM Loetmichel: LeelooMinai: i would be careful with such "foam" assumptions
07:43 PM LeelooMinai: What do you mean - it was made from something light to look like the real thing.
07:43 PM Loetmichel: i once had a girlfriend that was half my size and about half my weight... but had a 2nd dan in karate and an apprenticeship as blacksmith...
07:43 PM LeelooMinai: To basically troll people watching here move the stack effortlessly.
07:44 PM Loetmichel: ... THAT girl could LIFT ;)
07:44 PM Loetmichel: we once were out getting crates of beer and coke
07:45 PM Loetmichel: she came out of the van, 2 crats of beer in one hand and 2 crates of soda in the other... and moved them like they were made of foam...
07:45 PM Loetmichel: the looks of the passers by...
07:46 PM Loetmichel: it was plain funny.
07:47 PM LeelooMinai: Hmm, wish they were using mm/s everywhere not mm/min
07:48 PM LeelooMinai: Easier to imagine imo
07:49 PM LeelooMinai: I was binge watching robotwars and battlebots last week - lots of fun there.
07:53 PM {HD}: Hi, I have a parport that shows up like this... http://dpaste.com/1R3N8DM ... I have entered all the 'addresses' into my .hal file and none of them allow machine control...any ideas?
07:54 PM MacGalempsy: is the machine enabled?
07:54 PM roycroft: we just had a (very rare for us) thunderstorm
07:54 PM MacGalempsy: HD have you used HAL to test the connections?
07:54 PM roycroft: that kind of thing can happen when it gets up to 28 degrees all of a sudden
07:54 PM roycroft: things are very unsettled
07:55 PM MacGalempsy: we had thunder on sunday that was simultaneous flashes and bangs, probably within 100yds of the house
07:55 PM MacGalempsy: on saturday we got 6.5in of rain
07:56 PM {HD}: MacGalempsy: this configuration has worked on a different parallel port so I was only changing the address. I don't know how to use hal to check the port.
07:56 PM roycroft: i don't like painting when the humidity is >80%
07:56 PM roycroft: but oh well
07:56 PM roycroft: today is my day for painting
07:56 PM roycroft: first day
07:57 PM roycroft: i have two rounds for the current project - the lathe stand itself, and the chip tray and top plate for the stand
07:59 PM MacGalempsy: you can either check them thru the GUI or thru HALCMD
08:06 PM {HD}: OK, cool. After dinner I'll go mess round some more.
08:06 PM MacGalempsy: HD if you go thru terminal and do the HALCMD then you can do a show Pins and know the addresses are correct
08:07 PM {HD}: OK, let me walk right back down there before I start eating.
08:07 PM * roycroft needs dinner, but needs to finish painting first
08:09 PM {HD}: MacGalempsy: I dont see a 'show pins' command for halcmd...
08:09 PM * Loetmichel needs to go to bed, in 4 hours i have to wake up and ready myself for work
08:10 PM {HD}: list pin?
08:10 PM {HD}: halcmd list pin = *blank line
08:10 PM MacGalempsy: its been a bit since I did it last. let me look it up
08:11 PM MacGalempsy: http://www.linuxcnc.org/docs/html/hal/tutorial.html
08:11 PM MacGalempsy: look at 1.1
08:11 PM MacGalempsy: show pin
08:11 PM MacGalempsy: halrun
08:11 PM MacGalempsy: then show pin
08:12 PM {HD}: Hum... still blank
08:13 PM MacGalempsy: are you sure the parport card is linux compatible?
08:13 PM MacGalempsy: can you see that it is loaded?
08:14 PM {HD}: MacGalempsy: Did you click my dpaste? ^^
08:15 PM MacGalempsy: ok I see it, but I use MESA cards, so just trying my best to help
08:15 PM MacGalempsy: http://www.linuxcnc.org/docs/2.4/html/hal_parallel_port.html
08:15 PM MacGalempsy: ah. you need to loadrt hal_parport
08:16 PM MacGalempsy: hal doesnt know how to read it unless the component is installed
08:16 PM MacGalempsy: loadrt hal_parport cfg="0"
08:16 PM MacGalempsy: then do a show pins
08:16 PM MacGalempsy: grabbing a bite. will check in with you in a bit
08:17 PM Defhammer: I wanted to check if the forums are down... i seem to not be able to connect to them
08:19 PM {HD}: I get errors on loadrt: open(/dev/parport0): No such file or directory
08:19 PM LeelooMinai: Hmm, any idea what internal pins like motion.current-vel have as a unit? I have mm now, but the value I get from that pin seems like some internal representation.
08:21 PM TurBoss: Hello, does any one know how i can tell my python component in what coordinate system I am relative or machine?
08:22 PM LeelooMinai: Hmm, isn't it always relative unless you prepend G53?
08:22 PM TurBoss: oh
08:23 PM TurBoss: and how I can obtain them? I'm currently showing machine coords
08:24 PM LeelooMinai: I know they are stored in the variables file, but not sure when the file is saved - if on exit, on every change, or what.
08:24 PM TurBoss: ok thanks
08:24 PM TurBoss: Hi {HD} whats up?
08:25 PM {HD}: Yo! Just waiting for the 'dinner bell'
08:25 PM TurBoss: good
08:29 PM {HD}: I guess its more of a buzzer/beeper than bell.
08:29 PM TurBoss: :)
08:50 PM gregcnc: has anyone implemented polar interpolation for C axis, like Fanuc G12.1 and cylindrical G7.1?
09:04 PM TurBoss: ok I found
09:04 PM TurBoss: g5x_offset
09:09 PM pcw_home: motion.current-vel is in machine units/second
09:09 PM LeelooMinai: right, figured it out by now.
09:10 PM TurBoss: is posible to get the feed of each joint?
09:11 PM LeelooMinai: TurBoss: I think all the pins from HAL config window are available - are you consulting it?
09:11 PM TurBoss: ok thanks will check
09:12 PM LeelooMinai: motion.current-vel shows current speed
09:12 PM TurBoss: I would like to show feep per axis :D
09:20 PM TurBoss: ok found it joint.0.vel-cmd
09:20 PM TurBoss: Thanks
09:21 PM LeelooMinai: Right, weas going to say you could use that - thought it's "commanded", so not 100% "real" I guess
09:21 PM TurBoss: is to blinks a led strip
09:21 PM TurBoss: *blik
09:22 PM TurBoss: now the real question: How I can acces joint.0.vel-cm from python?
09:22 PM LeelooMinai: Doing Christmas lights with linuxcnc? :)
09:22 PM TurBoss: hahahah
09:22 PM TurBoss: could be
09:22 PM TurBoss: I mean a led bar
09:22 PM TurBoss: :D
09:25 PM LeelooMinai: Hmm, started "tuning" my steppers and quickly ran into "join 0 following" error. Wish there was more clue what is the error... Is it coming from linuxcnc, mesa driver, or what.
09:25 PM TurBoss: https://imgur.com/NPJ7c3H
09:25 PM LeelooMinai: Some kind of DRO?
09:26 PM TurBoss: yep
09:26 PM TurBoss: position works
09:26 PM TurBoss: is recycled
09:26 PM LeelooMinai: Nowadays it's easier to just use some tablet or monitor:)
09:26 PM TurBoss: from a weight measurement equipment
09:29 PM TurBoss: ok found the axis dictionary
09:29 PM TurBoss: :D
09:29 PM * TurBoss moves to machine room
09:29 PM TurBoss: http://linuxcnc.org/docs/2.6/html/common/python-interface.html 3.2
09:30 PM TurBoss: oh old doc
09:30 PM Crom: vok got my linear bear holes for the new sopindle mount turned on the lathe
09:31 PM Crom: now waiting on the ball screw
09:33 PM TurBoss: s.axis[1]["velocity"]
09:35 PM pcw_home: LeelooMinai: following errors occur because the feedback path (stepgen position in this case) has deviated from the commanded path
09:36 PM LeelooMinai: How could it deviate - I have steppers with no feedback...
09:37 PM pcw_home: with a stepgen, this can occur for a number of reasons, most commonly insufficient stepgen headroom above linuxcnc velocity and accel settings
09:38 PM LeelooMinai: The hostmot stepgen?
09:38 PM pcw_home: The stepgen (well all stepgens) have local (to linuxcnc) feedback
09:39 PM LeelooMinai: So with a mesa card scenario, how does one adjust the "headroom"?
09:40 PM pcw_home: for any stepgen, you set the stepgen accel and velocity about 25% higher than LinuxCNCs per axis limits
09:40 PM LeelooMinai: I had 5μs pulse width but I modified it to 2.5μs and thought that would give me better speedds potentialy.
09:41 PM pcw_home: it would allow higher pulse rates (but the stepgen velocity limit will limit this also)
09:42 PM LeelooMinai: Rate is defined by STEPLEN/SPACE?
09:43 PM pcw_home: basically you get a following error because the stepgen settings wont allow the requested rate (so the feedback position falls behind)
09:43 PM pcw_home: the maximum rate is bounded by 1/(stepspace+steplen) and the stepgen maxvel setting
09:44 PM LeelooMinai: RIght, but, I was able to do 30 mm/s with 5μs and cannot do 35 mm/s with 2.5μs, so it must be something else.
09:44 PM LeelooMinai: And I increased maxvel to 100
09:44 PM pcw_home: stepgen maxvel probably
09:44 PM LeelooMinai: I set it to 125
09:46 PM pcw_home: stepgen maxaccel also needs headroom (and the headrooms should be ~1.25 x linuxcncs axis values not huge)
09:46 PM LeelooMinai: I have 500 for ACCEL and 625 for MAXACCEL for stepgen.
09:46 PM pcw_home: ok thats good
09:47 PM pcw_home: what are steplen/stepspace and scale?
09:47 PM LeelooMinai: 2550/2550/1280
09:47 PM LeelooMinai: Does SCALE matter? I thought it's just for mapping steps to distance?
09:48 PM LeelooMinai: But I did not check it - maybe I think it's something it is not.
09:49 PM pcw_home: well the max steprate in hz would be scale*maxvel
09:50 PM LeelooMinai: I did not achange scale - it was correct for my machine before the speed change, so probably it is still correct.
09:50 PM LeelooMinai: I mean when I moved 1mm it moved 1mm.
09:51 PM pcw_home: so for example 1280steps/mm* 35mm/sec -=44800 Hz max step rate
09:51 PM pcw_home: how did you make your original config?
09:52 PM LeelooMinai: It was long time ago - first used some config generator, then corrected some things by hand later probably.
09:53 PM pcw_home: if you used pncconf, there are some bugs in the stepgen setup
09:54 PM LeelooMinai: Does {EMCMOT] SERVO_PERIOD = 1000000 matter much in this case?
09:54 PM pcw_home: thats the normal 1KHz rate which is fine
09:55 PM LeelooMinai: I see some debug pins in hal config on hm2
09:56 PM LeelooMinai: Can they be used to deduce anything?
09:56 PM pcw_home: some notable pncconf stepgen setup issues:
09:56 PM pcw_home: Older versions set P= 50 but it should be 10000
09:56 PM pcw_home: also for mm machines the PID maxerror soune be set to .01 (not .0005)
09:56 PM pcw_home: s/soune/should/
09:57 PM LeelooMinai: I don't have any P... isn't it for servos or something?
09:57 PM LeelooMinai: I have MIN_FERROR and FERROR = 0.005
09:57 PM LeelooMinai: in the AXIS section
09:58 PM pcw_home: Those are probably too small
09:58 PM LeelooMinai: Hmm, right, probably the generator used inches
09:59 PM pcw_home: pncconf sets a number of constants wrong for mm machines
10:00 PM LeelooMinai: 0.0005 is half a mil, so .01 sounds right
10:00 PM LeelooMinai: Since mil is 12.5 microns
10:00 PM pcw_home: also pncconf does set up PID loops (and P values) for the stepgens
10:00 PM LeelooMinai: I guess I will just convert all those values to metric
10:00 PM LeelooMinai: And that's wrong?
10:01 PM LeelooMinai: A, does, weird, I have not PID stuff in my file.
10:01 PM pcw_home: I think the very early pncconf (maybe 4 years ago) didn't use PID
10:01 PM LeelooMinai: Generated by PNCconf at Thu Nov 13 17:57:48 2014
10:01 PM LeelooMinai: Well, that's not that old.
10:02 PM LeelooMinai: O, wait, it's 2017 already...
10:02 PM pcw_home: also the pncconf that generated that could have been a fair bit older
10:03 PM LeelooMinai: Hmm... Maybe I should use the new one, then diff-compare the file I have with generated.
10:03 PM LeelooMinai: And add things that are missing;
10:03 PM pcw_home: I would widen the ferror limits to say 0.1 and 0.02
10:04 PM pcw_home: 0.1 for max ferror
10:04 PM LeelooMinai: Right, trying it now
10:05 PM LeelooMinai: Right, seems it helped
10:06 PM LeelooMinai: Moved at 40mm/s fine
10:06 PM LeelooMinai: And 54 too - good, thx, tomorrow I will be able to do more.
10:07 PM pcw_home: it should go until you drives lose enough torque to stall
10:08 PM LeelooMinai: Right, I also have this encoder I attached to X for now, that I will use to verify nothing weird happens.
10:10 PM pcw_home: hardware limit with stepgen/stepspace at 2550 each: max step rate is ~196 KHz or about 150 mm/s
10:11 PM LeelooMinai: 100mm/s seems fine - encoder goes to 0 with 10cm to right and back movement.
10:12 PM LeelooMinai: I will try 150, but that may be scary.
10:13 PM pcw_home: hand over estop...
10:16 PM LeelooMinai: I think it stalled
10:17 PM pcw_home: well that's expected at some point
10:18 PM LeelooMinai: So when it stalls, is it stepper limitation, driver hardware limitation, too long steps set?
10:20 PM pcw_home: its usually torque loss due to driver voltage limits
10:20 PM LeelooMinai: A, ok, 120 works, so I am pretty happy with this. Will do more tests tomoorowa, thx.
10:22 PM pcw_home: NP
