01:41 AM Deejay: moin
03:51 AM _unreal_: veegee, go weld something
05:09 AM _unreal_: no one awake?
05:09 AM _unreal_: sigh
05:09 AM _unreal_: cant sleep
05:12 AM rmu|w: its noon around here, so, yes, awake
05:12 AM _unreal_: noon?
05:12 AM _unreal_: EU?
05:12 AM _unreal_: 6AM here
05:12 AM rmu|w: central european dst
05:12 AM _unreal_: FINALLY just found these tree frogs that have been in my room
05:13 AM _unreal_: fun with the tropics
05:13 AM _unreal_: start churping REALLY loud and cant locate them.
05:13 AM _unreal_: there in a fold in the metal of the sliding window
05:13 AM _unreal_: going to be fun getting them out
05:20 AM _unreal_: two DEAD tree frogs MUCH better
05:22 AM jthornton: test
05:24 AM XXCoder: pong!
05:29 AM jthornton: https://gnipsel.com/images/chickens/cinnamon-queens/
05:31 AM _unreal_: those are some pretty hot chicks
05:31 AM jthornton: they like to be hot
05:34 AM veegee: 6 am here too, just woke up
05:36 AM jthornton: 5:34 AM here been up since 4:00 AM imagine that
05:37 AM veegee: why?
05:37 AM jthornton: 3 day old chicks
05:37 AM jthornton: https://gnipsel.com/images/chickens/cinnamon-queens/
05:38 AM jthornton: well they are 4 days old now
07:27 AM veegee: WOW the new Optrel Crystal 2.0 PAPR helmet is AMAZING
07:27 AM veegee: MUUUUCCCH better than the lincoln viking helmet crap that everyone seems to like
07:28 AM veegee: It's better in every way that matters - fit, weight, adjustment, sensitivity, instant darkening response, external controls, auto shade control
07:28 AM veegee: literally every single aspect of this helmet is better than the lincoln viking
07:28 AM veegee: And the PAPR system is great. It maintains air flow and regulates the fan to compensate for restrictions
07:29 AM veegee: I'm so glad I returned that lincoln viking crap
07:29 AM veegee: I think they made the viking for fat head obese americans
07:30 AM veegee: The optrel default middle of the adjustment range fit my head perfectly. On the Viking, I had to tighten everything almost as tight as it could go. How fat are American heads these days...
07:33 AM gregcnc: i hope I don't have to take this hole lathe apart. one gib adjuster seems to be stuck
07:37 AM veegee: gregcnc D: you have a hole lathe?!?
07:38 AM gregcnc: two entire lathes and one in pieces
07:39 AM veegee: I wish I had a hole lathe. Mine can only cut on the outside of things
07:39 AM gregcnc: if your lathe can't make holes you got a raw deal
07:40 AM gregcnc: Mine makes all kinds of holes
07:40 AM veegee: :( that whole thing flew right over your heaed
07:40 AM veegee: head
07:41 AM veegee: Speaking of head, I just measured mine and it's 57cm which seems to be about average and a "medium" on most sizing charts I see
07:41 AM gregcnc: it didn't, my typing is terrible
07:41 AM veegee: So it's not like I have an abnormally small head. Probably more than Americans are fucking fat
07:42 AM methods_: i thought lincoln just made shitty welders
07:42 AM methods_: who knew they made shitty helmets too
07:42 AM veegee: A lot of people like the viking (from my reading online), which is why I bought it
07:43 AM veegee: I could have tolerated its other shortcomings but the dealbreaker was that the auto darkening turned off when TIG welding and blinded me
07:43 AM methods_: yeah i don't think i'd be too happy about that
07:44 AM gregcnc: how are auctions doing right now?
07:45 AM methods_: i haven't noticed an uptick yet
07:45 AM methods_: should pick up soon though lol
07:45 AM veegee: Auctions for what?
07:45 AM methods_: for all the things
07:45 AM methods_: boeing ded, ford bankrupt....again
07:45 AM gregcnc: many were cancelled
07:46 AM methods_: all their vendors ded
07:46 AM gregcnc: locally. I'm watching a couple machines
07:47 AM methods_: i'd wait and see what happens unless you're in a hurry
07:47 AM methods_: might take awhile before the full effects of this tsunami are understood
07:47 AM gregcnc: well i'm wondering if anyone is buying now, these aren't in demand
07:48 AM methods_: i don't know anyone buying
07:48 AM methods_: everyone is hunkered down
07:48 AM methods_: there are going to be some interesting opportunities coming out of the event horizon of this
07:48 AM methods_: if you make it out
07:50 AM gregcnc: people are saying commercial realestate will be destroyed as co. shift to work from home in the future
07:50 AM methods_: yeah i think so too
07:50 AM methods_: i think a lot of people are realizing there is no need for them to have an office
07:51 AM gregcnc: if it actually happens, they couldn't have asked for a better "green deal"
07:53 AM methods_: it's definitely going to be interesting to see what comes out of this
07:53 AM gregcnc: a lot fo resent
07:55 AM methods_: and ventilators lol
07:55 AM methods_: this is going to put every ventilator company in the world out of business
07:56 AM gregcnc: interesting thought, countless new entries in that market plus huge surplus after
07:57 AM methods_: yep
07:57 AM gregcnc: hipster will be like look at what I made with this vent I found in the trash...
07:57 AM gregcnc: it will be the new pallet
07:57 AM methods_: hahahah
08:12 AM unterhaus: I'm hoping for a surplus of oxygen concentrators, there is a real shortage now
08:16 AM _unreal_: r unterhaus?
08:16 AM _unreal_: what do you want with a concentrator?
08:24 AM JavaBean: you can use the concentrator to make oxy for a oxy/**** torch. amongst other things
08:25 AM unterhaus: I would like to switch from oxy/acetylene to oxy/propane. Propane uses a lot more oxygen. Then I don't have to go to the welding shop for gasses
08:26 AM unterhaus: last time I got acetylene, they gave me a leaky tank. Really annoying
08:27 AM unterhaus: propane is much cheaper and the grill bottles last a lot longer than my acetylene tank
08:33 AM dirty_d: i wonder if you could make an electric torch
08:33 AM dirty_d: sorta like a plasma cutter, but lower temperature and slower flow
08:33 AM dirty_d: like blow air through an arc to heat it
08:34 AM dirty_d: or argon
09:20 AM rmu|w: dirty_d: https://www.sciencedirect.com/topics/chemistry/cold-plasma
09:25 AM dirty_d: groovy
10:20 AM _unreal_: unterhaus, how do you capture the O2
10:20 AM _unreal_: do you have a recovery pump?
10:21 AM _unreal_: just wondering the setup if you have a working one
10:25 AM gregcnc: are nursing homes getting wiped out in every state?
10:31 AM unterhaus: _unreal_ you just feed the o2 into a torch
10:31 AM unterhaus: some states are not so bad. Then there are states like florida that are hiding the numbers
10:32 AM gregcnc: 7 weeks into a lockdown here in IL and nursing homes and jails are rampant with covid
10:32 AM unterhaus: my mother in law's nursing home just tested evereyone and there were no cases. They did their own lockdown. Staff works 7 on/7 off. stay on premises
10:32 AM gregcnc: these are facilities with limited mobility already
10:33 AM unterhaus: Staff is tested when they come on duty
10:33 AM gregcnc: either what we are doing isn't working or I don't know
10:34 AM unterhaus: the problem is no testing for most of these workers. It's obviously not coming from inside the nursing home, someone brought it there
10:34 AM unterhaus: MIL's home is staggeringly expensive. Very few medicaid recipients.
10:36 AM gregcnc: 2457 deaths in IL, 1000+ in nursing homes
10:36 AM unterhaus: I know someone that works as a doc for a nursing home. It has gotten in. Workers have gotten it. Fortunately, she does telemedicine
10:36 AM unterhaus: The big outbreaks are in nursing homes, prisons, and meat packing plants.
10:37 AM gregcnc: my dad know someone in a facility. 70+ diabetes, tested positive is doing OK.
10:38 AM unterhaus: that's good, there seems to be a genetic component to how bad it affects people
10:38 AM gregcnc: always is
10:39 AM gregcnc: my son gets sick all the time and is sick for days, my daughter rarely and is usually one day. except for flu this winter which was very hard on her
10:40 AM unterhaus: my wife rarely gets sick, which is good because she sees a lot of patients under normal circumstances.
10:40 AM unterhaus: unfortunately, she doesn't seem to have passed this down to our kids
10:40 AM gregcnc: what kind of patients?
10:41 AM gregcnc: general, ER?
10:41 AM gregcnc: I had a dr tell me all the exposure essentially keeps them healthy
10:44 AM perry_j1987: morning
11:06 AM veegee: https://www.princessauto.com/en/detail/5-in-tungsten-carbide-flat-disc/A-p8722670e would this be decent for sharpening tungsten?
11:07 AM veegee: Or should I get a silicon carbide bench grinder wheel?
11:16 AM methods_: i just use a little belt sander lol
11:17 AM _unreal_: unterhaus, oh has that much volume?
11:17 AM _unreal_: or do you use multi machines?
11:18 AM _unreal_: ganged?
11:18 AM _unreal_: for volume
11:21 AM veegee: methods_ I have a belt sander too, never thought of that. I'll give it a shot
11:21 AM methods_: yeah i just put my tungsten in a drill and hit it on the belt sander
11:21 AM methods_: drill keeps it spinning evenly theoretically
11:21 AM veegee: methods_ yeah that's what I do
11:21 AM veegee: but even spinning it by hand is more than sufficient
11:22 AM veegee: The only thing is that it gets hot and burns my fingers
11:22 AM veegee: Spin slow though, to get the straightest grind marks
11:22 AM methods_: yeah i suppose you could use a pin vise or something if you don't feel like using a drill
11:22 AM methods_: then no finger burn
11:23 AM veegee: Guys, I really love this optrel crystal 2 PAPR helmet
11:23 AM veegee: Can't say it enough
11:23 AM veegee: no more tungsten dust in the lungs
11:24 AM _unreal_: no more tonguing the lungs ehh
11:24 AM Tom_L: take your pick. tungsten or covid
11:26 AM _unreal_: covid
11:40 AM veegee: why does it have to be one of those?
11:41 AM veegee: The PAPR filter blocks virus particles too
11:41 AM veegee: but I'm not afraid of the coronavirus. It's so easy to prevent it if people would just stay the fuck home
11:41 AM veegee: but people are retarded and the retarded americans deserve what they get
11:46 AM Tom_L: some are yes
11:46 AM Tom_L: not all of us
11:46 AM veegee: Of course, that goes without saying
11:47 AM veegee: But _most_ are braindead retarded. Half of you voted for an orange turd, more than half of you believe in an invisible man in the sky, etc.
11:47 AM veegee: I'm so thankful to live in Canada
11:48 AM veegee: People are starting to be stupid here too though. I see more cars parked on the street lately. People need to stay the fuck home. Now is the time to take it more seriously or it'll just come back
11:50 AM Tom_L: seems like they're more foolish around the costal states
11:52 AM Tom_L: coastal*
11:54 AM _unreal_: veegee, the numbers are NOT at all accurate. hospitals are getting paid $30k per covid victom.... and there are HUGE numbers that are being discoverd to be faulse reportings... MEDIA wont cover it
11:54 AM veegee: Yeah for sure
11:54 AM _unreal_: coroners are sueing everywhere
11:54 AM _unreal_: now
11:54 AM veegee: cable news is a joke
11:55 AM veegee: I mean I'm not scared of death, which is why I'm not afraid of the virus
11:55 AM _unreal_: because there "" CLIENTS" if you will where classifed as covid. and they had """ no idea """ when it is manditory they are informed
11:55 AM veegee: I've been through more pain than 99.9% of people can imagine
11:56 AM _unreal_: veegee, https://www.justice.gov/opa/pr/harvard-university-professor-and-two-chinese-nationals-charged-three-separate-china-related
11:56 AM _unreal_: Harvard is tied to covid
11:57 AM veegee: I'm about to do something stupid myself
11:57 AM _unreal_: covid IS man made
11:57 AM veegee: I'm going to put a 7" flap disc rated for 8,600 RPM into my 6" angle grinder rated at 9,000 RPM
11:57 AM veegee: _unreal_ don't assume that
11:57 AM veegee: I studied 4 years of immunology and virology. There's no evidence that it's man made
11:58 AM veegee: Don't get me wrong, it's certainly possible and viral DNA is modified all the time with plasmids
11:58 AM _unreal_: I spent shy of 10 years working for the jackson lab
11:58 AM _unreal_: :)
11:58 AM _unreal_: www.jax.org
11:58 AM veegee: But man made to what extent?
11:58 AM veegee: Viruses mutate extremely quickly
11:58 AM _unreal_: corona is 99% related to sars and a few others
11:59 AM veegee: first of all, it's not called "corona"
11:59 AM _unreal_: infact the RNA is the same except for a few chances
11:59 AM _unreal_: covid
11:59 AM veegee: it's a coronavirus in the coronaviridae family
11:59 AM _unreal_: changes
11:59 AM _unreal_: will with in the range of knock outs
11:59 AM veegee: And yes it's very similar to viruses found in the wild, which is why it's highly likely it's natural
12:00 PM _unreal_: that virus is an animal kingdom virus non human transmitable
12:00 PM veegee: omg that's wrong on so many levels
12:00 PM veegee: I love you but everything about that sentence is so wrong
12:00 PM veegee: humans are part of the animal kingdom
12:00 PM _unreal_: you love me??? I'm blushing I never new
12:00 PM _unreal_: ;)
12:01 PM veegee: Well I talk to you all more than I talk to my parents
12:01 PM _unreal_: yes but are chromosomes are very different.
12:01 PM pcw_home: Many pandemics are tied to animal husbandry
12:01 PM veegee: ^
12:01 PM veegee: _unreal_ doesn't matter
12:01 PM _unreal_: when I worked at the lab. we had a um...
12:01 PM _unreal_: um
12:01 PM _unreal_: wtf was it called
12:01 PM veegee: I wish I could explain all of it but there's so much material
12:01 PM _unreal_: tizzers
12:01 PM _unreal_: outbreak
12:01 PM _unreal_: I forget the spelling
12:02 PM veegee: I studied virology, immunology, microbiology in a lot of detail
12:02 PM veegee: the genetics of it, right down to the molecular biology of it
12:02 PM _unreal_: killed me to have to put down my personal study colony :( SJL's
12:02 PM veegee: exactly how proteins bind to the receptors and protein kinematics and all that
12:03 PM veegee: ALso worked in a microbiology lab
12:03 PM _unreal_: I left the lab because I couldnt take the lesbians any more
12:03 PM veegee: ^ LOOOOLLL
12:03 PM veegee: my lab professor was a lesbian
12:03 PM veegee: oh man that's insane
12:03 PM _unreal_: then you know what i mean
12:03 PM veegee: but she's awesome, I love her
12:03 PM _unreal_: at the lab they are the FAT crew cut kind
12:04 PM veegee: she also has a lathe and turns wood so I keep in touch with her
12:04 PM _unreal_: man hater kind
12:04 PM veegee: she's the one that taught me how to operate a lathe when I was very new to all this and still in school
12:04 PM _unreal_: cool
12:05 PM veegee: Anyway, point is, I have a looooot of knowledge about this and so far nothing smells fishy
12:05 PM veegee: Can't make a conclusion by looking at the virus particle or its genome
12:05 PM veegee: And I'm 100000% sure it wasn't made from scratch
12:06 PM veegee: It may have been heavily modified from a similar virus, but there's no insane crazy conspiracy
12:06 PM veegee: And the technology is not new and researchers do it every day all around the world
12:07 PM veegee: Whatever properties it has is more an accident than anything intentional
12:07 PM veegee: At the end of the day, most people are fucking stupid and I wouldn't mind if they were wiped off the planet anyway
12:08 PM _unreal_: " most people are fucking stupid" NOT faulse :)
12:08 PM _unreal_: the glove mandates bs is beyond belief
12:09 PM _unreal_: I lost count watching poeple touch shit, EAT with gloves on. dig in ther pers etc.... with gloves on... I'm like yall are stupid
12:09 PM _unreal_: and the gloves on the ground outside of businesses
12:10 PM _unreal_: well time to go get gas so I can mow the lawn
12:10 PM Tom_L: just finished that
12:11 PM veegee: Time to potentially win a darwin award putting a 7" flap disc on a 6" angle grinder rated for 500 more RPM than the disc
12:11 PM veegee: If I die, y'll can have my toys
12:12 PM Tom_L: trim it with sissors
12:14 PM veegee: the flap disc?
12:14 PM veegee: It's a 3M cubitron II disc
12:14 PM veegee: There won't be any scissors left if I do that
12:14 PM tiwake: is there a way to see the mac address of the modem?
12:15 PM Tom_L: ahh not a flat stickon one
12:15 PM tiwake: ip route does now show it
12:15 PM veegee: tiwake what OS
12:15 PM veegee: and what modem
12:15 PM veegee: You can see the ARP table with `arp -a`
12:16 PM veegee: tiwake `arp -a` will show the mac addresses of all cached IPs
12:19 PM veegee: I'm going to wear a thick boarhide apron so if the disc does explode, it'll protect me a bit
12:19 PM veegee: my motorcycle jacket should help too
12:20 PM veegee: my cat's just sitting there watching me fumble around with the adjustments on this leather apron like an idiot
12:23 PM unterhaus_: at least once a day, the ethernet connection between my router and cable modem goes bad and I have to re-plug the cable
12:23 PM veegee: unterhaus_ when it does, investigate
12:23 PM unterhaus_: I re-plug the cable and it's fine
12:23 PM veegee: use a real OS like Linux
12:24 PM unterhaus_: I don't think the os is really in play. I feel like the connector isn't quite right somehow.
12:24 PM veegee: I mean use a real OS like Linux to investigate
12:24 PM veegee: see what's up with the link
12:25 PM tiwake: ^
12:25 PM unterhaus_: not sure what your proposed plan of action is
12:25 PM unterhaus_: my understanding is that bad ethernet cables or connectors is a multi-OS issue
12:25 PM veegee: :(
12:25 PM veegee: never mind
12:26 PM veegee: just swap the cable and see if that works
12:26 PM unterhaus_: I replaced it with a brand new cable, that's why I think it's the connector
12:26 PM veegee: I'm 99% sure it's not
12:27 PM veegee: when the link goes down, check your logs `dmesg`, `ifconfig -a`, etc.
12:27 PM unterhaus_: The router case was designed to push on the cable if it's too big, which seems like a design flaw
12:27 PM veegee: the OS will tell you how the link was lost
12:29 PM unterhaus_: this all started when the roomba somehow got tangled in the wires
12:29 PM unterhaus_: hate that thing
01:55 PM Thorhian: So on my Z axis I'm going to be making a counterweight using two chains. I was wondering if it was really neccessary to put the weight on its own rails or just leave it hanging? Hanging would be a lot easier but I'm not sure it would be okay?
02:01 PM _unreal_: thorhian? depends
02:01 PM _unreal_: if there is a chance it could start swinging thats an issue
02:01 PM _unreal_: IF your machine is going to make rapid movements up/down thats a problem
02:02 PM _unreal_: thorhian IMO you would be wiser to use a spring loaded compound pully
02:03 PM veegee: 7" angle grinders are where it's at
02:03 PM _unreal_: veegee, ?
02:03 PM veegee: flap disc wheels last wayyyyy longer
02:03 PM _unreal_: oh the lfap thing
02:03 PM _unreal_: flap
02:03 PM veegee: I'm going to get a proper 7" angle grinder
02:04 PM _unreal_: Thorhian, the idea is you have a steel cable attached to your Z it then goes to pulleys as needed to guide the wire if needed. then goes to a compound pulley setup and the other end goes to a HARD anchor. ONE end of the compound pulley is hard anchored. the other end is connected to heavy duty springs
02:05 PM _unreal_: just make a small long skinny box mount everything inside. anchor the box and run the cable upto Z
02:05 PM _unreal_: Thorhian, ?
02:10 PM _unreal_: I'm starting to get the electronics put together https://drive.google.com/open?id=1oHduYa2ANdWE6VH5DIhcMQi_ls1xkjhw
02:10 PM _unreal_: ve7it, what cha think
02:13 PM Thorhian: That would be interesting _unreal_ but I don't know if I have room for such a setup.
02:14 PM Thorhian: When it comes to swinging I could probably weld or screw on some guide posts or sleave for the weight to prevent swinging.
02:14 PM ve7it: _unreal_, that is one "interesting box!" mad max sytle!
02:14 PM ve7it: style
02:15 PM Rab: The weight would be constant, spring tension would be nonlinear.
02:18 PM Thorhian: Have you made something like what unreal was talking about?
02:18 PM Thorhian: Rab ?
02:26 PM _unreal_: RAB that is the reason for the compound pulley style
02:27 PM _unreal_: you get a very small stroke on the spring and a large stroke on the cable so your tension is very linear
02:28 PM _unreal_: especially if you use different sized pulleys to gear it down as well
02:28 PM _unreal_: would not take much to have a 2" pulley move = 14+ inches on the cable
02:29 PM _unreal_: rab sling shot launches use that setup so that you have constant pull
02:29 PM _unreal_: and tension
02:34 PM _unreal_: Thorhian, https://image.shutterstock.com/image-vector/loaded-movable-pulleys-spring-rope-260nw-263522999.jpg in this setup https://www.wired.com/2017/01/physics-of-a-compound-pulley/
02:38 PM _unreal_: pcw_home, I'm starting to get my box put together.
03:45 PM veegee: Good buy or no? https://www.princessauto.com/en/detail/60-lb-forged-steel-anvil/A-p8655573e
03:45 PM veegee: I'm just about to go and pick up some other stuff
03:46 PM XXCoder: isnt it traditional for blacksmith to make one themselves?
03:46 PM veegee: https://www.princessauto.com/en/detail/110-lb-steel-anvil/A-p8688442e
03:46 PM veegee: Alternatively there's this 110 lb one at for some reason the same price
03:47 PM veegee: I can return it anytime within a year. Not sure which one to get
03:47 PM veegee: and I don't understand why the one that's twice as heavy is the same pri e
03:47 PM _unreal_: I'd get the one made of metal
03:48 PM _unreal_: lead filled maybe?
03:49 PM veegee: They're both C45 cast steel
03:49 PM veegee: Some people are saying the 110lb one is not hardened steel
03:50 PM veegee: Leaning toward the 60 lb one
03:51 PM _unreal_: I'm not much of a metal forging guy
03:51 PM veegee: Should be a good starter anvil. If it sucks, back to the store it goes. Princess auto has the best return policy ever
03:52 PM veegee: I can return a used lead acid battery a year later for a full refund lol
03:52 PM veegee: But I don't. I only screw over greedy fucking companies like amazon
03:59 PM Deejay: gn8
05:21 PM dirty_d: I was messing around, is this outdated? http://linuxcnc.org/docs/2.8/html/user/user-concepts.html#_planning_moves
05:21 PM dirty_d: even if I make a loop moving 0.01" at a time for 5 inches, the machine moves the same speed as one g01 moving the full 5"
05:22 PM dirty_d: with 61, g64, and g64 with P and Q
05:23 PM Tom_L: yep
05:24 PM dirty_d: is the naive cam detector always on now?
05:24 PM dirty_d: well except for g61.1
05:26 PM Tom_L: try the same linear 5" _|-|_|-|_|-|_ and see if you get the same result
05:26 PM Tom_L: .01 each
05:27 PM dirty_d: im not sure what you mean there
05:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube/Test_cut.jpg
05:27 PM dirty_d: oh
05:27 PM Tom_L: make it change axis and stop each axis move and see
05:28 PM dirty_d: I think it's kinda wacky how the default mode is G64
05:29 PM dirty_d: if you're max acceleration is very low, you might break things
05:29 PM XXCoder: never saw light blue mitutoyo cal
05:30 PM andypugh: dirty_d: Interesting point.
05:31 PM dirty_d: I think G61 as the default would make the most sense, go exactly where programmed, but don't stop unnecessarily
05:33 PM Tom_L: andypugh, have you tried running that RTAI on hardware yet?
05:33 PM andypugh: Yes. That is what I was running my 5000 rpm stepper with.
05:34 PM Tom_L: ahh
05:34 PM Tom_L: but you blew it up!
05:36 PM dirty_d: I tried the stretch image with 2.8-rtpreempt on a B450M DS3H with a Ryzen 3 3200G for the hell of it and got about 45us max latency.
05:37 PM dirty_d: Is there some list that should be added to? I remember when I was figuring out what parts to use I couldn't find a list of latency numbers for modern hardware
05:47 PM tiwake: dirty_d: is that a high number?
05:51 PM dirty_d: tiwake, for software stepping it's not great, but for a mesa card it's good
05:51 PM tiwake: alright
05:51 PM tiwake: good to know
05:52 PM dirty_d: I think the appeal is that it's modern fast hardware that you can dual boot or something and use fusion360 or whatever
05:52 PM dirty_d: and cheap
05:53 PM dirty_d: amd just came out with new processors that are even cheaper I think
05:53 PM dirty_d: this has integrated graphics, so the new ones without might be better for latency
05:55 PM Thorhian: I mean, what would be hurting it's latency? The chipset? I'd imagine that the new cheap 3xxx CPUs would be great if the latency isn't terrible.
05:55 PM Thorhian: Plus the B550 chipset is coming, I wonder how it will fair.
05:56 PM Thorhian: Heck, I wonder how my 3700X and X570 mobo would fair. Probably terribly since it has a UEFI.
05:57 PM dirty_d: try it
05:57 PM dirty_d: I think the mobo I tried it on has UEFI too
05:57 PM dirty_d: yea it does
06:11 PM andypugh: dirty_d: Apparently you can run Fusion360 with Lutris: https://lutris.net
06:13 PM dirty_d: hmm, I did try it in wine, not a good experience
06:13 PM andypugh: I think Lutris and Wine are the same thing.
06:13 PM dirty_d: using remmina on linux to RDP to a windows PC works very well though
06:13 PM andypugh: Or very closely related
06:14 PM dirty_d: its almost as good as being on it locally
06:15 PM dirty_d: even on the rpi 4 it's usable
06:15 PM dirty_d: I wouldn't use it for anything that takes longer than like 5 minutes in fusion though
06:15 PM dirty_d: but on a better PC it's great
06:27 PM dirty_d: I had no idea I needed to tune PID for steppers
06:27 PM dirty_d: I didn't realize there was a problem till I jogged with an MPG wheel
06:27 PM dirty_d: it would oscillate sometimes
06:27 PM dirty_d: leaving P at 1000 and setting D to 10 fixed it
08:29 PM gregcnc: dang, no luck with my rusty gib screw
08:31 PM Tom_L: slot screw?
08:31 PM Tom_L: i've got one of those hammer screwdrivers that works for stuff like that sometimes
08:31 PM Tom_L: forgot what they're called
08:31 PM gregcnc: set screw
08:31 PM Tom_L: oh, skip that then
08:32 PM Tom_L: head stripped?
08:32 PM Tom_L: or just stuck
08:32 PM gregcnc: rusty. they don't actually tighten anything
08:36 PM gregcnc: three were fine this one obviously had coolant getting at the felt wiper that covers it.
08:38 PM Tom_L: i'm kinda surprised/dissapointed with this asrock q1900 mb latency. i figured it would be better than the current D5525 i have on the mill but it's not
08:40 PM Tom_L: gregcnc, you could try a straight hex wrench and tap the end of it maybe. not an L but a straight piece
08:40 PM Tom_L: maybe that along with some penetrant would jar it loose
08:41 PM gregcnc: you would think, but not so far
08:41 PM gregcnc: it's only like 3 threads worth of M8
08:41 PM Tom_L: that or heat but you probably don't want heat there
08:41 PM gregcnc: but only a 2.5mm hex through
08:45 PM _unreal_: ve7it, I just finished all of the major wiring inside the box except for the control wires
08:46 PM _unreal_: ve7it, I have a main breakout power distribution pcb/board I built. would you suggest using a fuse for each servo control board? OR one main fuse for the dc supply?
08:47 PM _unreal_: I would assume single fuses for the motor controller boards if anything
08:47 PM Tom_L: i would fuse each supply
08:47 PM Tom_L: ie 5v 48v etc
08:47 PM _unreal_: There is a mains fuse on the main transformer
08:47 PM Tom_L: and a main 120v
08:47 PM Tom_L: i got one on my spindle
08:47 PM _unreal_: I have a mains 12A 120v fuse for the big transformer
08:47 PM _unreal_: my spindle is a brushless
08:48 PM _unreal_: not setup yet
08:48 PM Tom_L: right
08:48 PM Tom_L: i used din rail fuse mounts on mine
08:50 PM ve7it: _unreal_, you have a big dc supply... it would not hurt to fuse the +25 and -25 lines. The drivers themselves run as constant current sources, so you are mostly protecting against shorts between the supply and the drivers
08:50 PM Tom_L: _unreal_, http://tom-itx.no-ip.biz:81/~webpage/rue/Control3.jpg
08:50 PM Tom_L: that power rail you can get from pcw
08:50 PM Tom_L: if you want any
08:50 PM Tom_L: jt might have them as well, i'm not sure
08:50 PM Tom_L: pretty handy
08:53 PM _unreal_: ve7it, so are you saying just on the mains DC
08:54 PM _unreal_: dont bother putting a fuse on each driver board?
08:54 PM Tom_L: i didn't
08:55 PM _unreal_: I built my own power rail
08:55 PM _unreal_: milled it
08:55 PM Tom_L: k
08:55 PM _unreal_: I think you'll like my breakout setup
08:55 PM Tom_L: those are just real handy with the screw terminals
08:56 PM _unreal_: ve7it, My next step is figuring out how to wire the servo controllers to the mesa
08:56 PM _unreal_: ve7it, what value should I use for the fuse?
08:56 PM Tom_L: you will need to find out what pins the step / direction are on on the mesa card
08:57 PM _unreal_: Tom_L, ve7it's drivers dont use step/dir
08:57 PM Tom_L: what do they use?
08:57 PM _unreal_: they use quadrature control for motion input
08:57 PM Tom_L: hmm
08:57 PM ve7it: fuses... start with something common like 15A
08:58 PM _unreal_: for 3 drivers
08:58 PM _unreal_: I've built 4 drivers but I'm not even really wiring in the A
08:58 PM _unreal_: Tom_L, What are the little uC boards with the pot's on them?
08:59 PM _unreal_: little 5v switching psu's?
08:59 PM Tom_L: 5 and 10 iirc
09:00 PM Tom_L: like two buck ea or less
09:00 PM _unreal_: I have a small psu that came from something I forget...
09:00 PM Tom_L: at the time
09:00 PM Tom_L: i needed 10v for my spindle control
09:00 PM _unreal_: od
09:00 PM _unreal_: odd
09:00 PM Tom_L: it's off the sherline
09:00 PM Tom_L: wasn't the normal +10 -10 swing
09:00 PM _unreal_: I assume those are just adjustable psu's
09:01 PM Tom_L: yeah
09:01 PM Tom_L: i set then put a dot of hot glue on it
09:01 PM Tom_L: you can get those same ones with a display too
09:02 PM _unreal_: ve7it, I'm pissing my self off I miss placed the serial adapter chips I still need to put one on one of the boards... not that I'm likely to use the last board but just the same
09:02 PM Tom_L: https://www.ebay.com/itm/Buck-DC-DC-Step-down-Converter-Power-Supply-Module-40V-5A-75W-Voltmeter/172326968508?hash=item281f7cdcbc:g:JIwAAOSwi0RXyJUC:sc:USPSFirstClass!67213!US!-1
09:02 PM Tom_L: similar
09:02 PM _unreal_: heh Tom_L I have lots of little supplys like that
09:02 PM Tom_L: i had some similar to those too
09:02 PM _unreal_: I use to do a lot with the drone/racing quad stuff
09:03 PM _unreal_: obama fucked up the RC market and I lost interest
09:03 PM _unreal_: :/
09:03 PM Tom_L: i built my first ones
09:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/5v_switcher.jpg
09:03 PM Tom_L: same chip
09:06 PM _unreal_: you built? or had boards fabed for ya
09:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/board3.jpg
09:07 PM Tom_L: there's the first one
09:08 PM Tom_L: i wanted a bunch so i had some made
09:10 PM Tom_L: that was before i figured out i could get em from china cheaper than the parts from DK
09:13 PM _unreal_: heh
09:13 PM _unreal_: + labor
09:19 PM _unreal_: google is acting strange?
09:22 PM _unreal_: ?
