01:48 AM Deejay: moin
03:51 AM fogl81: hello
04:01 AM fogl81: i am trying to compile user c hal comp, but i am getting "undefined reference to `hal_init'". I assume i am missing a -L option. What library should i include?
05:02 AM JT-Cave: morning
05:21 AM Tom_L: morning
05:44 AM Tom_L: fogl81, https://github.com/LinuxCNC/linuxcnc/blob/master/src/hal/hal_lib.c
05:53 AM fogl81: i found it, thank you, now i managed to compile and load a simple user hal module :)
05:57 AM JT-Cave: did you take notes on how you did it?
06:39 AM _unreal_: got out of bed, BURRRR that was an error
09:41 AM fogl81: JT-Cave, you mean me? I did not, but i can write them if someone would benefit from it.
09:41 AM Tom_L: you should
09:41 AM Tom_L: not alot of that gets done so i'm sure someone would appreciate it
09:42 AM fogl81: Maybe i could write something (an example) and it could be added next to python user module instruction/example?
09:42 AM Tom_L: that or on the wiki
09:43 AM Tom_L: or both
09:45 AM JT-Cave: fogl81, yes let me know when you get an example and I'll add it to the docs
09:46 AM fogl81: ok, i will
10:40 AM sorki is now known as srk
12:16 PM JT-Cave: pcw_home, can I run a single g203v/stepper on a 7i96 with just USB 5v to the 7i96?
12:18 PM pcw_home: I would think so. the 7I96 only draws about 200 mA by itself
12:19 PM pcw_home: if you add an encoder or a sserial remote device then it gets more iffy
12:19 PM pcw_home: (for a nominally 450 mA max USB port)
12:20 PM pcw_home: I test all our 7I96s with USB power
12:20 PM Tom_L: JT-Cave, that or a couple smps to power them all
12:21 PM Tom_L: for the range?
12:21 PM JT-Cave: just one stepper and no I/O
12:21 PM Tom_L: yeah
12:22 PM Tom_L: but how many will there be?
12:22 PM JT-Cave: just need to prove if 24v is enough to run the stepper or if I need 48v
12:22 PM Tom_L: gotcha
12:22 PM JT-Cave: just a test rig
12:28 PM Tom_L: you'd surely get better performance from 48v
12:29 PM JT-Cave: sure but do I need it or not is the question
12:33 PM _unreal_: well so far as I can tell I think my A axis on my hobbycnc board ether has some setting or wiring that I cant figure out WTF? or that axis on my 4 axis board is fried? I cant get it to step period
12:33 PM _unreal_: even swapped around signal wires the fucker just wont step
12:33 PM _unreal_: nothing
12:34 PM _unreal_: I'm wondering if that has anything to do with when I fried the board. still seems to work. but the A axis was the only one that didnt have anything plugged in to it and had its curent value turned all the way down
12:34 PM _unreal_: sigh
12:35 PM _unreal_: and my home machines design is deigned with negative access
12:35 PM _unreal_: to all control components
12:37 PM _unreal_: just mind blowing how the motion control board its self has no keying on some of the quick connect sockets. so you can fuck up plugging them in and plug them in OFF key or up side down doesnt matter
12:38 PM _unreal_: hence I drive 24v into ground once. as you can expect I found it AFTER I waited till smoke was AGRESSIVELY showing its self before I un plugged the power when it happend last year
01:02 PM Loetmichel: _unreal_: try again with 12 truck batteries in series as the PSU... you will find any short REALLY fast
01:02 PM Loetmichel: 2 12V batteries i mean
01:05 PM Eric__: pcw_home do you think you will have any 7i48 in stock any time soon?
01:05 PM Loetmichel: ... sometimes with some explosive sel-disassembly of the faulty part ;)
01:05 PM Eric__: "parts were liberated"
01:07 PM Loetmichel: <- tried to "help up" a weak PSU on a mini CNC router once... managed to reverse the leads from the two 12V7Ah gel blocks... result: http://www.cyrom.org/palbum/main.php?g2_itemId=12554&g2_imageViewsIndex=1
01:08 PM Loetmichel: "ups!"
01:09 PM pcw_home: Eric__ There are some being assembled now
01:10 PM Eric__: great, thanks!
01:56 PM _unreal_: so that confirms it, the motion controller is fine. its an issue with the motor controller my hobbycnc 4 axis
01:57 PM _unreal_: its like there is just no step signal being recived
01:57 PM _unreal_: the current tuning is working the motor on A is holding but its not reicving signal for motion
01:58 PM _unreal_: or the chip is just fucked up? who knows maybe there is a burn wire somehwere I can see
01:58 PM _unreal_: at this point I'm going to say its a FUCK IT and forget it
01:58 PM _unreal_: 4th axis is DOA?
01:58 PM _unreal_: oh well
01:59 PM _unreal_: My own igonorance for wilfully designing zero access to any of the components so I could fit it in the smallest space possible.
02:03 PM beachbumpete1: well that sucks
02:03 PM beachbumpete1: did you scratch build it?
02:27 PM _unreal_: ?
02:27 PM _unreal_: need more data
02:27 PM _unreal_: heh
03:03 PM _unreal_: so a bit upset top find that my 4th axis on my hobbycnc is NFG some how
03:03 PM _unreal_: I ordered a new 74hc14 chip. since it is the only thing I can replace. if that does not fix it I'm going to say FUCK IT for ever
03:04 PM _unreal_: or add some other motor floating motor controller board
03:04 PM _unreal_: not worth ripping everything apart
03:04 PM _unreal_: just for one axis
03:04 PM _unreal_: just like that servo controller I built. I'm going to build a new shell to house the motor controllers. because I dont know why they are not working at I cant access ANYTHIUNG AT ALL
03:05 PM _unreal_: 99% non accessable
03:05 PM _unreal_: by design
03:05 PM _unreal_: I dont know why I do that
03:09 PM t4nk_freenode: _unreal_, yeah, I hear that a tremendous lot about driver boards coming DOA on the one axis
03:10 PM t4nk_freenode: although... it's always you I hear it from
03:10 PM t4nk_freenode: :))
03:10 PM t4nk_freenode: I just couldn't resist heheh
03:10 PM _unreal_: this week I may dig into the ve7it driver since I have nothing else to do really
03:11 PM _unreal_: and I just addressed and found I killed any chance of having a 4th easy.
03:12 PM t4nk_freenode: almost pizza- time
03:14 PM _unreal_: god I have not even bothered to have lunch today
03:14 PM _unreal_: then again I got dragged next door again to go fix a problem
03:15 PM _unreal_: AGAIN
03:15 PM _unreal_: this time it was the washing machine
03:16 PM t4nk_freenode: did you ever think the old rag has the hots for you?
03:16 PM _unreal_: no idea and she's in her 80s
03:17 PM _unreal_: there is a LATCH pin on her washing machine, selenide driven
03:17 PM _unreal_: it was stock out and the lid would not close
03:17 PM t4nk_freenode: I personally find your arms-with-gorilla-hair pretty appealing, but for the old one.. she might lower her standards a bit if you're nice to her
03:17 PM t4nk_freenode: HO, STOP
03:17 PM t4nk_freenode: for God's sake
03:17 PM _unreal_: gorilla hair?
03:17 PM t4nk_freenode: I find it pretty SICKENING I meant to say of course!
03:17 PM t4nk_freenode: not appealing
03:18 PM t4nk_freenode: what happened there :(
03:18 PM _unreal_: I ended up pulling the power, and I figured it was a SENSE lever, only after messing with it it suddenly sucked back. which says to me the relay got stuck open some how
03:19 PM _unreal_: err solenoid
03:19 PM t4nk_freenode: last time I went over to a women's house to fix things...
03:19 PM t4nk_freenode: she said I was cute!
03:19 PM t4nk_freenode: ... as she was tending to my injuries :|
03:19 PM _unreal_: congrats?
03:19 PM t4nk_freenode: true story
03:20 PM _unreal_: I think I'm goiung to pour my self a drink
03:20 PM t4nk_freenode: I think I'm gonna wipe my rear end and leave the toilet now
03:20 PM _unreal_: !
03:21 PM Loetmichel: TMI
03:21 PM _unreal_: wash your hands there are enough germs going around LOL
03:21 PM t4nk_freenode: nah, I'm like that stand up guy... nothing can touch me man: I swam in raw sewage as a kid
03:22 PM Loetmichel: will not help him. people that use their phone on the loo should be punished... thats contaminated now.
03:22 PM t4nk_freenode: lol
03:22 PM Loetmichel: you may be. can you say that for all the people you will meet though?
03:23 PM t4nk_freenode: I wasn't on my phone
03:23 PM t4nk_freenode: I wasn't even on the loo ;)
03:24 PM t4nk_freenode: not that it would offend me though.. I just have the nasty experience to have dropped such a EEEEEE-thingy pc in the loo once
03:24 PM t4nk_freenode: so I never take anything in the loo ever ;)
03:24 PM t4nk_freenode: and no.. it didn't drop In... but got smashed on the floor
03:27 PM _unreal_: sounds like your trying to talk your self out of your last statement LOL
03:28 PM t4nk_freenode: ? I explicitly stated that it would not have offended me 1 bit
03:28 PM t4nk_freenode: I can do what I want, where I want ;)
03:29 PM t4nk_freenode: (except compiling stm32 with gcc atm for some reason)
03:34 PM _unreal_: ok now have my wires sorted out
03:34 PM _unreal_: I'm working on my RPI cnc controller
03:35 PM _unreal_: I have a db25 header in it right now. but I'm going top swap it with an other DB25 header which has higher guage wires one of those old RS DIY headers
03:35 PM _unreal_: wondering if I should have purchased a DB34 header?
03:36 PM _unreal_: that way I could have all 4 motor wire outputs and ALL i/o's from the protoboard. AND any rpi I/O outputs
03:58 PM _unreal_: no responces I see no one missed me
04:02 PM _unreal_: I'm thinking about designing AN OTHER new touch probe. super low profile.
04:02 PM _unreal_: but honistly who uses those things :)
04:21 PM Eric__: son pointed out the headstock on my guitar is cracked
04:21 PM Eric__: I guess i shouldn't have been making fun of gibsons
04:22 PM Eric__: Gibsons have been said to sound better after the headstock is broken/repaired
04:22 PM Tom_L: they're one of the best anyway ehh?
04:24 PM Tom_L: i guess Fender are ok too
04:29 PM JT-Shop: so far I think 24v will work for the target system... find out tomorrow
04:30 PM Tom_L: are you gonna treat these as self contained units or spread the psu across several?
04:31 PM JT-Shop: at this point I'm assuming each one will have it's own power supply
04:32 PM JT-Shop: but that is a thought to share them
04:32 PM Tom_L: maintenance wise that would be quick to swap one out
04:33 PM JT-Shop: yeah simpler to trouble shoot and one per would not take down half the lanes when it goes out
04:33 PM Tom_L: higher initial cost
04:34 PM Tom_L: shared psu could still be plug n go
04:36 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Chuck_Holder1.jpg
04:37 PM Tom_L: macro worked great on the threads... first time fit
04:37 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Chuck_Holder2.jpg
04:37 PM JT-Shop: you thread mill that?
04:37 PM Tom_L: both sides
04:38 PM Tom_L: i'm not happy with it though, it's not concentric enough to use
04:38 PM JT-Shop: oh second photo is the bottom?
04:38 PM Tom_L: yes
04:38 PM JT-Shop: now it makes sense lol
04:38 PM Tom_L: it's supposed to be a jacobs chuck adapter
04:38 PM JT-Shop: I guess no shoulder to register to?
04:38 PM Tom_L: instead of a taper fit
04:39 PM Tom_L: i'm not sure what it is really
04:39 PM Tom_L: threads look good though
04:40 PM Tom_L: i might try one with both female threads and put a threaded stub in the small one
04:40 PM Tom_L: that way i won't have to flip it
04:41 PM Tom_L: really should be done on a lathe but i don't have one
04:41 PM Tom_L: not good enough for that anyway
04:42 PM JT-Shop: looks like with a Click PLC my cost for components is $675 per lane
04:42 PM Tom_L: what did they expect?
04:42 PM Tom_L: or did they have any idea
04:43 PM JT-Shop: no clue, he didn't have anything that worked...
04:44 PM JT-Shop: the problem is PLC outputs are 24v so you need a 24v control stepper drive and a high speed output or you need a lower cost plc and a higher cost drive that takes ascii
04:44 PM Tom_L: should be ok with it, it's one of the main investments in his business
04:44 PM JT-Shop: over serial
04:44 PM JT-Shop: I'm betting the building and all that AR500 plate was the main investment
04:44 PM Tom_L: yeah
04:45 PM Tom_L: i suppose the plate isn't cheap
04:45 PM JT-Shop: I've never heard of AR500 only AR400 and another one like AR300 maybe
04:46 PM Tom_L: probably has to be certified too
04:47 PM JT-Shop: the AR500?
04:47 PM Tom_L: yeah
04:48 PM JT-Shop: no clue, the AR500 is mostly plates on the ceiling at a 45 and I think backup behind the rubber mountain
04:49 PM Tom_L: all i see is body size plate on a search
04:49 PM Tom_L: https://www.leecosteel.com/ar500-500f-steel-plate/
04:49 PM Tom_L: there we go
04:50 PM Tom_L: huh, that isn't certified
04:50 PM Tom_L: the mil spec stuff is
05:01 PM JT-Shop: planer parts are in St Louis...
05:06 PM roycroft: so less than a week away ...
05:06 PM Tom_L: unless they go to Or first
05:07 PM roycroft: it appears that this jst connector kit i got is going to work out after all
05:08 PM roycroft: i was looking at several cables that use those connectors, from several different devices
05:09 PM roycroft: and universally the male end of the cable is not an inline conector, but a pcb mount connector with the wires soldered to the pins protruding from the bottom of the connector, and heat shrink tubing around the pins
05:09 PM roycroft: i still don't know why i got any male pins with the kit
05:09 PM roycroft: but oh well
05:10 PM roycroft: it seems like a strange way to make cables, but i guess everyone is strange
05:13 PM Eric__: the internet has ruined everything, I tried looking up "virtual center" and the original meaning isn't present on the internet according to google
05:13 PM roycroft: that would be a player on a fantasy football team?
05:14 PM roycroft: or is center a position on a basketball team?
05:14 PM roycroft: i know in baseball it would be center fielder
05:14 PM roycroft: but i don't know much about other sports
05:15 PM Eric__: virtual center is a concept where the pivot point isn't located on the machine in question
05:15 PM Eric__: aka instant center
05:16 PM Tom_L: try virtual focal point maybe
05:16 PM Tom_L: or what you said
05:17 PM Eric__: virtual pivot point brings up a batch of bicycle nonsense
05:18 PM Eric__: but the internet did ruin this particular subject
05:33 PM JT-Cave: going to be a busy day tomorrow...
07:50 PM roycroft: well thank effing goodness - the president just signed the budget bill
07:51 PM Tom_L: don't think he was that happy about it
07:51 PM roycroft: he was very unhappy
07:51 PM roycroft: but he had to do it
07:51 PM Tom_L: i say let em shut down
07:52 PM roycroft: and see millions of people evicted in the dead of winter?
07:52 PM roycroft: and millions others with no money at all to eat?
07:52 PM Tom_L: 600 ain't gonna do squat for them
07:52 PM roycroft: and no money for the states to vaccinate their people?
07:52 PM roycroft: that is the stupid part of the bill
07:52 PM gregcnc: presses go brrrrrr
07:52 PM Tom_L: and all the other bloat added in
07:53 PM roycroft: it's the evicition moritorium, the extended unemployment benefits, the small business loans, and the money to distribute the vaccines that is the important part
07:53 PM roycroft: there is no bloat at all in the covid relief bill
07:53 PM roycroft: the issue is that the bill was attached to the omnibus budget bill
07:53 PM Tom_L: i shouldn't get drawn in this..
07:53 PM roycroft: and there is bloat there, for sure
07:53 PM Tom_L: i preach otherwise ya know :)
07:54 PM roycroft: well it's good to know the facts :)
07:54 PM gregcnc: that's how politicians do business
07:54 PM Tom_L: about channel cleanliness n all...
07:54 PM roycroft: it is, and it is what is wrong with politics, and what makes me tired of itall
07:54 PM roycroft: all i'm saying is, whatever bad things may be in the legislation, it was essential that the covid relief bill be signed into law
07:55 PM roycroft: but i'll also repeat sending checks directly to people is stupid
07:55 PM roycroft: and now i'm done :)
07:55 PM XXCoder: why?
07:56 PM roycroft: oh, i should also disclose that my employer has been hit badly by the pandemic, and needed the first round ppp money to tide the company over until now
07:56 PM gregcnc: so halogen edison bulbs aren't even a new thing
07:56 PM XXCoder: isnt new bill have pp also?
07:56 PM roycroft: that money is almost gone, and while we're cutting expenses, the survival of the company is in jeopardy right now
07:56 PM Tom_L: so are alot of other small business'
07:56 PM roycroft: so round 2 of ppp will directly benefit me - it will ensure i have a job for a few more months
07:56 PM roycroft: yes
07:57 PM roycroft: xxcoder: what makes sense to me is not to just give people money
07:57 PM roycroft: but to keep people employed
07:57 PM roycroft: so the ppp program was great
07:57 PM gregcnc: give it to businesses, because they will be frugal?
07:57 PM XXCoder: what about people already not have a job?
07:57 PM XXCoder: ie like me? :)
07:57 PM Tom_L: restaurants for example will die regardless
07:57 PM roycroft: they are required to use it directly for payroll
07:57 PM roycroft: actually, a lot of restaurants have been saved by ppp
07:57 PM XXCoder: i was laid off at july
07:58 PM roycroft: restaurants around here mostly are take-away now
07:58 PM roycroft: and there is a huge drop in revenue
07:58 PM roycroft: but ppp allows them to keep their full staff
07:58 PM roycroft: when they can finally open for indoor dining again, they'll be ready
07:59 PM Tom_L: until the 2nd virus reaches us?
07:59 PM gregcnc: just wait until inflation hits
07:59 PM roycroft: the last pandemic of this magnitude was over 100 years ago
07:59 PM roycroft: the next one could start tomorrow
07:59 PM roycroft: but it could also take 100 years
08:00 PM gregcnc: "this magnitude"
08:00 PM roycroft: or 500 years
08:00 PM roycroft: we don't know
08:00 PM roycroft: all we know is what is happening right now
08:00 PM Tom_L: 100 years ago we weren't as globally attached either
08:00 PM XXCoder: scientists is saying theres another 2 ponental plagues also
08:01 PM Tom_L: so what then may have been confined to a region will hit us all
08:01 PM roycroft: the extended uneployment benefits not only helped people with conventional jobs who were laid off, but supplemting their income to approach what they made while working, it offered for the first time unemployment benefits to self-employed people
08:02 PM XXCoder: direct checks is something to simplus ecomony also
08:02 PM XXCoder: people would pay for stuff
08:02 PM roycroft: the bad news of the day is that there are two confirmed cases of the new, more infectious strain, in ontario
08:02 PM XXCoder: :(
08:02 PM Tom_L: benefits to self-employed were available before
08:02 PM roycroft: actually, what people did with the first round is pay down debt
08:02 PM roycroft: they did not stimulate the economy at all
08:03 PM roycroft: not really for gig workers
08:03 PM roycroft: that huge number of people who are in between self-employed contractors and employees
08:04 PM Tom_L: it was a more lengthy process than a regular employee but they were available
08:05 PM roycroft: i said i was done a while ago, and i meant it, but felt a little further discussion to try to clarify things would not be bad
08:05 PM roycroft: but the slope is starting to get slippery
08:06 PM roycroft: so i'll conclude once again and say this:
08:06 PM Tom_L: or just conclude without
08:06 PM gregcnc: your'a re a smart guy everyone should just take your advice
08:06 PM roycroft: i don't like that we had to have that bill, and i don't like how it adds to the debt (but that's a different discussion), but i think it was necessary and i'm glad the president finally kept his word and did what he said he would do
08:07 PM roycroft: gergcnc: i should hope that smart people would listen to what i say and consider it
08:07 PM roycroft: i don't expect people to agree with me
08:07 PM gregcnc: but your way is the only way
08:07 PM gregcnc: and everyone should get it
08:07 PM roycroft: when have i ever even remotely insinuated that?
08:07 PM roycroft: i'm not insistent on points of view or approaches to solving problems
08:08 PM roycroft: the only thing i'm insistent on is that facts are facts
08:08 PM gregcnc: cool story bro
08:08 PM roycroft: there is no such thing as "alternative facts"
08:08 PM roycroft: there are different facts
08:08 PM gregcnc: if you can get "real" facts today
08:08 PM roycroft: i.e. the set of facts that i use may be different to the set of facts that you use
08:09 PM roycroft: but where those facts intersect, they are identical
08:09 PM gregcnc: lol
08:09 PM Tom_L: there are way too many facts of convenience today
08:09 PM roycroft: actually there are not
08:09 PM roycroft: but there are way too many things that are called facts that are really not facts
08:09 PM Tom_L: put them in a blender and they come up different
08:09 PM roycroft: that's not how it works
08:10 PM roycroft: it's not how science works
08:10 PM gregcnc: you don't read enough different sources
08:10 PM roycroft: and science doesn't care if you believe in it or not
08:10 PM gregcnc: you'll find these "facts"
08:11 PM roycroft: i fear that the current regime has tainted our concept of reality even more severely than it was before 2017
08:11 PM roycroft: and that we may not recover from that during my lifetime
08:11 PM gregcnc: it's not even that, started a long time ago
08:11 PM roycroft: but that does not mean i, or anyone else, should give up on finding the truth
08:11 PM Tom_L: way before that date for sure
08:11 PM roycroft: yes, of course it did
08:11 PM roycroft: i said "even more than"
08:12 PM roycroft: i did not say it started in 2017
08:12 PM Tom_L: i didn't say you did
08:12 PM roycroft: misconstruing reality for political purposes started thousands of years ago
08:12 PM gregcnc: human nature will never change
08:13 PM roycroft: sure it will
08:13 PM roycroft: we're animals - living things
08:13 PM gregcnc: another fact?
08:13 PM roycroft: we will evolve
08:13 PM roycroft: or we will go extinct
08:13 PM roycroft: that
08:13 PM roycroft: is how life works
08:13 PM gregcnc: extinct?
08:13 PM roycroft: yes
08:14 PM roycroft: if we stop evolving we'll go extinct
08:14 PM roycroft: one way or another
08:14 PM gregcnc: sound fun
08:14 PM roycroft: it's unlikely to happen in any of our lifetimes
08:15 PM roycroft: it will happen some day
08:15 PM roycroft: that day may be millennia or eons from now
08:15 PM roycroft: but it will happen
08:15 PM roycroft: certainly by the time our sun becomes a red dwarf, if we have not solved the problem of interstellar travel by then
