12:18 AM veegee_: https://www.youtube.com/watch?v=dhKk-mfMlAM
12:25 AM veegee_ is now known as veegee
12:25 AM veegee: There's something off about that guy, it's irritating
12:25 AM veegee: But I do love the machinery
12:25 AM veegee: That Cincinnati is absolutely beautiful
12:25 AM XXCoder1: way too many special effects
12:25 AM XXCoder1: I call it "ADD" type video where they cant have video section last more than second or 2 without special effects or cut
12:34 AM XXCoder1: i range on watching from hobby to pro
12:35 AM XXCoder1: but i tend to avoid people doing risky stuff
12:35 AM XXCoder1: or ADD type videos
01:08 AM CaptHindsight: veegee: I've moved heavier machines with less
01:08 AM CaptHindsight: sounds kinds spoiled if yah asks me
01:24 AM enleth_: this guy is a fabricator, not a machinist and he admits it
01:25 AM enleth_: stuff he makes and sells has been used and praised by machinists, though
01:25 AM enleth_: frankly, I don't quite get the "not a real machinist" thing
01:26 AM enleth_: what *is* a machinist?
01:26 AM veegee: my stepper motors
01:26 AM veegee: nonetheless, I was on the fence about him before this video, now I know for sure I can't stand him
01:29 AM CaptHindsight: there are lots of making stuff videos that people rave about
01:29 AM CaptHindsight: most to me are like watching the making of a sandwich
01:31 AM CaptHindsight: "now we are going to cover turning the nut with a wrench"
01:33 AM CaptHindsight: https://www.youtube.com/watch?v=VBvlKNjmb14
01:39 AM veegee: LOL yes
01:39 AM XXCoder1: high quality
01:40 AM veegee: But I love thisoldtony
01:40 AM XXCoder1: me too
01:41 AM veegee: Ok regarding the wrench video above, not sure if the people commenting are in on the humour or actually really don't know how it works
01:42 AM sensille: quite instructive
01:42 AM veegee: Because if they're grown ass adults and seriously asking those questions, it answers a lot of questions I had about humanity
01:42 AM veegee: like "why does religion even exist?" and so on
01:44 AM CaptHindsight: the religion discussion is like the Brawndo discussion
01:44 AM sensille: not a single comments sounds serious to me
01:45 AM veegee: "THANK YOU!!! Straight to the point what I needed!!" I don't know, that one sounds genuine
01:45 AM sensille: "clear and concise"
01:47 AM veegee: After having the 5000K workshop lights on all day, sitting in front of a computer with two 3000K lamps beside me feels nice and cozy
01:48 AM veegee: I forgot how beautiful 2700K-3000K high CRI lights are
01:48 AM veegee: food, animals, humans all look nicer under that colour temperature
01:49 AM XXCoder1: high cri nice
01:49 AM CaptHindsight: womens bathroom lamps
01:49 AM veegee: CaptHindsight they're called "vanity lights"
01:50 AM veegee: and yes those are beautiful, much lower than 2700K though
01:50 AM veegee: and part of it is the glowing hot tungsten filament and clear glass
01:50 AM CaptHindsight: we used to get asked why people looked so good under those fixtures only
01:50 AM veegee: yeah, the answer is colour temperature, and to a much lesser extent, CRI
01:51 AM veegee: I'm going to rip the shitty power supplies out of all the overhead shop lights and wire them directly to a true constant current DC power supply
01:52 AM veegee: I absolutely hate that 60Hz flicker. Why can't these assholes make proper current sources...
01:54 AM CaptHindsight: they can, they just want the extra profit
01:54 AM veegee: I'm stocking up on HP6030A power supplies but they're still damn expensive.
01:55 AM CaptHindsight: or if the market is already very competitive they want to make the lower cost fixture so that more people will buy it
01:55 AM veegee: Also getting a bunch of R4850G2 telecom power supplies which are great value but not a true current source.
01:56 AM enleth_: veegee: swapping in a bigger capacitor sometimes helps those shitty supplies not flicker as much
01:56 AM veegee: enleth_ indeed, I tested and verified
01:56 AM enleth_: they often try to be constant current and have the correct topology
01:56 AM veegee: enleth_ but a DC source is better
01:56 AM enleth_: but just can't keep up
01:56 AM veegee: they usually have the current limit part right like you said
01:56 AM veegee: if I feed them about 90VDC, they have zero flicker
01:57 AM veegee: so I'm just making sure the lighting circuit is not connected to any wall outlets and just powering everything with something like a HP6030A. That way I can control it over GPIB too lol
01:59 AM enleth_: honestly, wouldn't a rectifier bridge and a large capacitor be all this needs?
01:59 AM enleth_: for the circuit, I mean
01:59 AM veegee: Yes
01:59 AM veegee: I have 3 phase too, wayyyy better
02:00 AM veegee: For now just sticking my bench power supply there until my next digikey/mouser order
02:16 AM Deejay: moin
02:20 AM CaptHindsight: enleth_: caps are expensive
02:21 AM CaptHindsight: i have a portable 120VAC fixture that does not have a single cap in it and they use the LED's themselves as the rectifiers
02:21 AM CaptHindsight: the flicker is near sickening
02:25 AM XXCoder1: bleh
02:26 AM XXCoder1: when it gets out of tune it literally sickens me
02:26 AM XXCoder1: my sis home new led lights was flickering as it was crap ones
02:26 AM XXCoder1: she was already planning to replace em
02:29 AM CaptHindsight: hah hackers is on Cinemax east
02:30 AM CaptHindsight: 1995
02:32 AM veegee: XXCoder1 CaptHindsight yeah the sick feeling is real
02:32 AM veegee: It's motion sickness
02:32 AM veegee: Same thing happens when I play FPS video games with a narrow field of view
02:32 AM veegee: Diphenhydramine instantly cures you though
02:33 AM veegee: Or widen the field of view/get rid of flicker
02:33 AM XXCoder1: isnt that boat motion sickness or whatever motion sickness motion?
02:33 AM veegee: XXCoder1 they're all related; it happens when the brain gets confused from sensory inputs it doesn't think make sense
02:34 AM veegee: So diphenhydramine cures that regardless of the cause
02:34 AM XXCoder1: counter or rx only?
02:35 AM veegee: For example, with the FPS video games, some people (like me) get super nauseous if the field of view doesn't match real life surroundings
02:35 AM veegee: over the counter
02:35 AM CaptHindsight: i get used to it in a minute
02:35 AM veegee: used as a antihistamine, sleep aid, cure motion sickness
02:35 AM XXCoder1: vee heh not easy for me, my view field is 180
02:35 AM veegee: Also if you take it in higher doses, makes music sound much better
02:35 AM veegee: Not that simple
02:36 AM veegee: I find that if I set the FOV to 105º (default is more like 85º), it becomes a non issue
02:36 AM XXCoder1: unfortunately it doesnt work for me
02:36 AM veegee: I don't get seasick or carsick though. Just the video games an flicker is a problem for me
02:36 AM veegee: yeah everyone is different, it's really interesting like that
02:37 AM veegee: diphenhydramine is one of my favourite drugs for so many reasons
02:37 AM XXCoder1: counter or rx?
02:37 AM veegee: over the counter
02:37 AM XXCoder1: as well as try if cheap enough
02:37 AM veegee: all the "nighttime" versions of the cold/pain medications simply add it in lol
02:37 AM veegee: if you want the pure form, it's sold as a sleep aid
02:38 AM XXCoder1: amazon results is all "allegy"
02:38 AM veegee: yeah it's a first generation antihistamine too
02:38 AM veegee: every pharmacy ever and most grocery stores will have it
02:38 AM veegee: I use 50mg every day to help me sleep as well, highly effective
02:39 AM veegee: obviously long term use not a good idea as with almost any drug, but hey we're all dead anyway
02:39 AM veegee: the only question is when
02:39 AM XXCoder1: ill try it later not now
02:53 AM NoGodDamnIdea: morning everyone
02:54 AM XXCoder1: hey no idea
03:03 AM veegee: Why do people use MAPP gas?
03:03 AM veegee: That is, instead of acetylene
03:05 AM veegee: Oh, I guess safety
03:53 AM -!- #linuxcnc mode set to +v by ChanServ

04:56 AM Loetmichel: **GAAAH!** Why me? just got a call from the car mechanic... 3/4 done with the convertible... he just opened the oil pan and found the giude rail of the camshaft chain... another few 100 eur... now we cracked the 5kEur repair price... and that for a 2001 E46 BMW 318i convertible. :(
04:57 AM bjorkintosh: why? because you bought a > 2 year old german car.
04:58 AM bjorkintosh: I have a sneaking suspicion that their designers deeply resent the old german cars lasting forever. so they 'fixed' it.
04:58 AM bjorkintosh: 2 year and no longer.
04:58 AM bjorkintosh: 3 if you're lucky.
05:15 AM bjorkintosh: either that or they've employed one too many MBAs.
05:18 AM Loetmichel: bjorkintosh: thats why i buy 20 year old german cars.
05:18 AM Loetmichel: still less prone to fail than the new ones that are designed to fail
05:22 AM enleth_ is now known as enleth
05:33 AM JT-Cave: morning
06:10 AM unterhaus_: I always wondered where the Wera t-handled hex wrenches were, they are called "hexagon screwdriver"
06:33 AM Spida_ is now known as Spida
11:33 AM veegee: Loetmichel totally not worth repairing that
11:34 AM veegee: I mean paying some wrench monkey to repair it. DIY worth it though.
11:36 AM Thorhian: How goes it?
11:38 AM Thorhian: I have a question for the people here that use flood coolant on their milling machines. How do you control your pump motor?
11:42 AM Loetmichel: veegee: i know. but i am already 4k in.
11:45 AM * JT-Shop has one more light to replace and the machine shop will be bright and cheery again
11:47 AM veegee: JT-Shop so the difference between dark and gloomy and bright and cheery is just one light!?
11:47 AM veegee: That must be one hell of a light
11:47 AM veegee: Thorhian VFD
11:51 AM Thorhian: veegee: What if I just want to turn it off or on. I know you can put a solenoid valve on the output but I don't want to choke the pump.
11:51 AM Thorhian: Also, a VFD only works on a three phase motor from what I know?
11:52 AM veegee: To put it simply yes, but it can also drive a single phase motor
11:52 AM veegee: IF you know what you're doing
11:52 AM veegee: But if you have a single phase motor, you don't need a VFD. So define "control"
11:53 AM veegee: You want to start/stop the motor based on what?
11:53 AM veegee: (well still need the VFD if you want variable speed)
11:54 AM Thorhian: Based on whether flood cooling is on or off in linuxCNC. Like I said, I've seen people use solenoids on the output to stop the flooding but doesn't that damage the pump given enough time?
11:54 AM Thorhian: If the pump is on while the output is closed?
11:54 AM veegee: Depends on the type of pump
11:55 AM veegee: What kind of pump is it?
11:55 AM veegee: Some may damage the pump, others may overload the motor, other types will be just fine
11:56 AM veegee: Wait why not just use a contactor to turn the motor on and off?
11:56 AM Thorhian: I'm looking to get a sumbmersible pump from harbor freight or other store like many DIY'ers do for making a flood cooling system.
11:56 AM Thorhian: Okay, that's an option.
11:56 AM veegee: Those are centrifugal, so you'll be totally fine
11:56 AM veegee: you can block the output
11:56 AM Thorhian: Oh, so I can do that. Cool.
11:56 AM veegee: But unless I'm missing something very obvious, why would you want to do that?
11:57 AM veegee: It's easier just to put a contactor to turn the motor on and off...
11:57 AM veegee: Like it's the same amount of hardware required. You still have a control signal line, and given the choice of solenoid valve or motor contactor, why would you choose the solenoid valve?
11:58 AM Thorhian: Faster to turn off or on I suppose. The pump can stay on and you get back up to pressure when you turn the flood back on I suppose.
11:59 AM Thorhian: I bet you could do both for power saving purposes as well.
11:59 AM Thorhian: As in, if no job is running, you can turn off the pump entirely.
12:00 PM veegee: Yeah I guess
12:00 PM veegee: If you're talking about this kind of pump: https://www.harborfreight.com/16-hp-submersible-utility-pump-1600-gph-63319.html yeah it's safe to block the output
12:00 PM veegee: it has a "head lift" spec, so if you try to pump water that high, it's equivalent to blocking the output
12:00 PM Thorhian: Yeah, that would be it, except something more powerful.
12:01 PM veegee: they're low pressure high volume pumps
12:01 PM Thorhian: I was thinking of getting a 3/4 HP one.
12:03 PM Thorhian: You got any recomendations on a cheaper coolant pump? Otherwise, I was just going to get a regular sumbmersible pump.
12:05 PM veegee: No, those seem reasonably priced to me
12:05 PM veegee: Can't imagine why you need 3/4 HP but you do you dawg
12:06 PM Thorhian: XD I want real flood cooling, not just a trickle. Maybe I'll go with 1/2 hp.
12:08 PM Thorhian: Especially since I want to try my hand at stainless and titanium milling at some point.
12:09 PM _builtin is now known as __builtin

12:17 PM veegee: Why can't we get hydraulic piston pumps for that price?
12:17 PM veegee: They're at least $3,000 for a variable displacement piston pump
12:19 PM veegee: Although... for that price, don't mind trying to use it as a hydraulic pump instead of a gear pump
12:24 PM veegee: Thorhian no compromises https://www.princessauto.com/en/7-hp-2-in-non-submersible-displacement-water-pump/product/PA0008994337
12:47 PM Loetmichel: *giggle* Wife just now: "I'll take that crutch to my physioterrorist and see what she has to say about it." $me: "physioWHAT?" "Physiotherapist, sorry. Although it feels more like the former some days."
12:48 PM roycroft: https://www.amazon.com/HHIP-3012-8110-Gallon-Coolant-1PhaSE/dp/B00N41FXSG
12:48 PM roycroft: i have a couple of those, although mine can run on 120/240v
12:49 PM roycroft: i use one at 240v on my router table, and the other at 120v on my horizontal bandsaw
12:50 PM roycroft: i should think that pump would be fine for flood coolant on a machine up to bridgeport class or maybe even a bit larger
12:52 PM veegee: Yeah 3/4 hp sounds overkill
12:52 PM veegee: That puts out more volume than a wide open garden hose
12:53 PM roycroft: 1/8hp or even 1/12hp should be fine
12:53 PM veegee: That's what I thought. Like a strong fish tank pump would even work
12:53 PM roycroft: if the impeller can handle the coolant
12:54 PM roycroft: that's more my concern than the power - whether it's rated for what you're pumping through it
12:54 PM veegee: As in, the viscosity?
12:54 PM roycroft: if it's a magnetic impeller that's coated in teflon, great
12:54 PM veegee: Or corrosion of the impeller?
12:54 PM roycroft: corrosion
12:54 PM roycroft: viscosity is usually not an issue with flood coolants
12:55 PM roycroft: some machines do use non water soluble oil coolant, and viscosity could be an issue there
12:55 PM veegee: I actually use a membrane diaphragm pump
12:55 PM roycroft: but most coolants are petty thin, so they can squirt on things easily
12:56 PM roycroft: that woroks
12:56 PM roycroft: works
12:56 PM veegee: I never had an issue and I put it through hell - like nasty oil with metal shards
12:57 PM sensille: is 400W enough for a small metal bandsaw?
12:57 PM veegee: Funny story how that started. I first bought it to power my "bidet". I had a motorcycle accident years ago and it destroyed my shoulder and as you all know, I don't use toilet paper because it's disgusting. I always use water for cleaning perfectly every time
12:57 PM veegee: But with one entire arm paralyzed, I had to build a shower for my butt
12:58 PM veegee: diaphragm membrane pump worked great for that lol
12:58 PM veegee: It's designed as an RV water pump so it puts out ~60 PSI
12:58 PM veegee: Once my shoulder healed, I repurposed it as a coolant pump
12:58 PM veegee: sensille more than enough
12:59 PM veegee: that's 1/2 hp dude
01:00 PM sensille: good, thanks
01:03 PM veegee: Just to put it into perspective, my water fountain for my cats is 10W
01:03 PM veegee: and even _that_ would suffice for a small vertical mill lol
01:03 PM roycroft: as i said, i have a 1/8hp pump and it works fine for the bandsaw
01:03 PM roycroft: 1/12hp would be fine for the bandsaw
01:03 PM roycroft: 1/12hp is ~65w
01:03 PM veegee: Yeah. Even this would be fine lol: https://www.amazon.ca/Catit-LED-Flower-Fountain/dp/B07KYXFJQ2
01:04 PM sensille: fountain? hm. i meant the main motor?
01:04 PM veegee: It's powered by one of those USB wall phone chargers
01:04 PM veegee: OH
01:04 PM sensille: :)
01:04 PM veegee: that's a different story entirely
01:04 PM sensille: sorry, i asked at the wrong moment :)
01:04 PM veegee: we were talking about coolant pumps for the past hour
01:05 PM veegee: roycroft has good experience with bandsaws
01:05 PM roycroft: well, the past five minutes for me :)
01:05 PM roycroft: i own bandsaws and i cut stuff with them
01:05 PM veegee: I have an industrial one with a 5hp motor and it's overkill for what I need
01:05 PM roycroft: i guess that counts as good experience
01:05 PM roycroft: my current metal bandsaw is a 7x12 horizontal saw, with a 1hp motor
01:06 PM roycroft: it works fine
01:06 PM roycroft: what i'm really excited about is that my blasting cabinet components are on their way
01:07 PM roycroft: i am *finally* going to get that thing upgraded so it works decently
01:07 PM roycroft: after owning it for ~20 years and cursing at it for ~20 years
01:08 PM sensille: i'm thinking about getting this one: https://www.paulimot.de/maschinen/bandsaegen/metallbandsaegen/1120/metallbandsaege-gfw4013-vario
01:08 PM veegee: sensille those are nice, but not sure why people use those instead of an abrasive chop saw
01:09 PM sensille: i have neither
01:09 PM veegee: What's the advantage of a band saw over something like this: https://www.amazon.ca/DEWALT-D28710-14-Inch-Abrasive-Chop/dp/B00551DJBQ
01:09 PM veegee: They both make nice clean cuts
01:09 PM roycroft: abrasive chop saws are really really really really noisy, and really really really really messy
01:09 PM sensille: that's what i was about to ask
01:09 PM roycroft: i have an abrasive chop saw
01:10 PM roycroft: i don't think i've used it in well over a decade
01:10 PM roycroft: i hate them
01:10 PM veegee: ah makes sense
01:10 PM roycroft: i should sell mine
01:10 PM sensille: i basically like the smell of burning steel, but it's also nice to get it out of the basement again
01:10 PM roycroft: i only keep it in case my bandsaw breaks
01:11 PM roycroft: a chop saw is generally a lot faster than a bandsaw
01:11 PM roycroft: and i know some folks don't mind the noise and the mess, so i can see how it makes sense for them
01:11 PM sensille: i'm fed up with cutting steel stock with the hacksaw
01:12 PM roycroft: but a bandsaw does not have to be tended while it's cutting
01:12 PM roycroft: if you can arrange your workflow so that you can do other things in the shop while the saw is cutting, you really just have to keep an eye on it while it's operating
01:12 PM veegee: LOL yes the speed
01:12 PM veegee: I was buying some metal from the local metal dealer and they had an automatic band saw. It wasn't even thick metal and it took forever to cut it
01:12 PM roycroft: i don't find that it costs me time to use the bandsaw, because i always have something else to do while it's cutting
01:13 PM veegee: I was just thinking why not chop saw and it'll be ready in less than 10 seconds
01:13 PM veegee: But I was waiting for it for 10 minutes
01:13 PM roycroft: contrary to how i may sometimes appear on channel, i'm actually a pretty laid-back person
01:13 PM roycroft: i'm patient and not in a hurry
01:14 PM veegee: sensille yeah I have a reciprocating saw with metal cutting blades, that works well
01:14 PM roycroft: i own air-cooled vws
01:14 PM roycroft: for us the journey is at least as important as the destination
01:14 PM roycroft: us, meaning vw owners
01:14 PM veegee: for rough cuts though since it's hand held
01:15 PM roycroft: a lot of folks get port-a-band saws and build little stands for them
01:15 PM roycroft: that may be an option, depending on your needs and budget
01:15 PM veegee: A lot of them come with those stands these days
01:15 PM veegee: example: https://www.amazon.ca/Anbull-Portable-Removable-5-inch-Spotlight/dp/B08DHKF8MJ
01:16 PM sensille: i don't need it portable, though
01:16 PM sensille: 1100W. makes me wonder again if 400W are enough
01:17 PM * roycroft is about ready to order his new jointer
01:24 PM NoGodDamnIdea: hey yall
01:24 PM veegee: sensille yeah it is
01:24 PM veegee: the blade is very thin
01:25 PM NoGodDamnIdea: so I did manage to make some progress on the cnc :D
01:25 PM NoGodDamnIdea: its not fully running yet but its something
01:26 PM JT-Shop: what are you getting?
01:26 PM roycroft: i need to find a place that can make me some custom length air hoses
01:27 PM roycroft: i know of a couple hydraulic shops in town - i wonder if they also do pneumatic stuff
01:30 PM * JT-Shop just uses push on fittings or repair fittings depending on the hose
01:43 PM NoGodDamnIdea: _unreal_, let me know when you are on I got a few questions for you
03:17 PM SpeedEvil is now known as Guest27445
03:47 PM errorxyz: Hello everyone! Can somebody help me with Gmoccappy with PlasmaC?
03:52 PM XXCoder1 is now known as XXCoder
03:56 PM JT-Shop: the forum is your best bet for those two...
03:57 PM errorxyz: fter solving many little riddles I'm now stuck for days with a table that can jog and home, but the RUN and CONFIG tab of gmoccapy is empty and I can't for days now figure out why.
03:57 PM errorxyz: I figured out to start linuccnc from the commandline to get at least hints of errors in the background and I noticed exceptions 'no attribute "materialList'
03:59 PM JT-Shop: you might try Axis to get your machine running quick
03:59 PM JT-Shop: or Touchy if you have a touch screen
04:00 PM * JT-Shop uses http://www.qtpyvcp.com/
04:00 PM errorxyz: Also there is a TypeError regarding OFFSET_AV_RATIO: "Argument must be a string or a number". The value in the file is "0.5". It is supposed to be a ratio.
04:00 PM JT-Shop: https://github.com/jethornton/mill_touch_v6
04:00 PM JT-Shop: that's mine
04:01 PM errorxyz: Thx hmm I looked at the axis gui and I thought gmoccapy looks much more polished ... so I kind off trusted it more.
04:03 PM errorxyz: I have just found out there is a QtPlasmaC. Which needs Linuxcnc2.9. Is that is that a good idea to switch to this right away?
04:03 PM JT-Shop: master aka 2.9 will break from time to time so be aware
04:04 PM JT-Shop: do you have a plasma table?
04:04 PM errorxyz: I have built one yes
04:04 PM errorxyz: using the parallel port so far
04:05 PM errorxyz: mill touch doesn't seem to be far plasma?
04:06 PM JT-Shop: I just use axis on my plasma table
04:06 PM errorxyz: with thc?
04:06 PM JT-Shop: plasmac is way too complicated for a plasma table
04:06 PM errorxyz: how ironic
04:06 PM JT-Shop: Mesa THCAD-300
04:06 PM JT-Shop: I have one of the first prototypes of the THCAD :)
04:07 PM errorxyz: what is plasmac made for then?
04:07 PM JT-Shop: complicated plasma
04:07 PM htasta: hence the C
04:07 PM htasta: plasmaC[omplicated]
04:08 PM htasta: :D
04:08 PM CaptHindsight: oh hush, how complicated kin uh plasma be?
04:09 PM errorxyz: but the axis gui will also use plasmac in the background, no?
04:09 PM errorxyz: or are you talking about sort of just milling around with your plasma head?
04:09 PM roycroft: do any of you have a vulcan mig welder from harbor freight?
04:10 PM roycroft: i'm thinking it's time for me to upgrade from my ancient 120v lincoln, and they're on sale right now
04:10 PM roycroft: vulcan are their "premium" brand
04:10 PM CaptHindsight: errorxyz: what would you really like to have? A custom plasma GUI or just a modern looking one or something else?
04:11 PM CaptHindsight: there has been all sorts of new work on GUI's in the past few years but they aren't in the official distribution
04:13 PM CaptHindsight: roycroft: I have not purchased one but I have heard good things about the new ones at HF
04:14 PM * JT-Shop runs the last part in the VMC then calls it a day
04:14 PM * JT-Shop only has blue welders...
04:15 PM CaptHindsight: roycroft: https://www.youtube.com/watch?v=WbNiPPMC2ng
04:15 PM errorxyz: I want somethings cut my stuff precisely and reliable, where I can switch materials, adjust parameters quicky and save them. I don't want to custom gui for the good looks.
04:16 PM errorxyz: sorry for the typos
04:17 PM CaptHindsight: roycroft: https://www.youtube.com/watch?v=Z3Qia6l742w
04:17 PM roycroft: i have some welding projects coming up where i'll be welding on 3/8" steel, and with my little lincoln i have to do that in 3 passes
04:18 PM roycroft: and it's still hard to get good penetration
04:18 PM errorxyz: I are doing cnc welding?
04:18 PM CaptHindsight: errorxyz: if you like Gmoccappy with PlasmaC I'd ask on the forums https://forum.linuxcnc.org/plasma-laser
04:18 PM roycroft: i could stick weld, i suppose
04:19 PM roycroft: my tig welder is 250a, and that's plenty for stick welding 1/2" steel
04:19 PM CaptHindsight: errorxyz: beware "All PlasmaC development is now done on QtPlasmaC which is a full configuration including a custom GUI."
04:20 PM CaptHindsight: errorxyz: https://forum.linuxcnc.org/plasmac/41883-qtplasmac-release
04:21 PM CaptHindsight: 15 Mar 2021 so the paint isn't even dry yet
04:21 PM bill is now known as Guest44309
04:22 PM CaptHindsight: http://linuxcnc.org/docs/devel/html/plasma/qtplasmac.html
04:25 PM CaptHindsight: roycroft: the philosophy behind low cost inverter welders made in China as explained to me by the Chinese makers is low cost, light weight and lasts a year or two
04:25 PM CaptHindsight: used near everyday for 8+ hours per day
04:25 PM roycroft: i have an everlast inverter welder
04:25 PM roycroft: it is tig/stick
04:26 PM roycroft: i've had it for about 10 years now, and it is great
04:26 PM CaptHindsight: a welder in China typically would ride their scooter/motorcycle from job to job
04:26 PM JT-Shop: errorxyz, for reliable stick with a released version of LinuxCNC, 2.8 is the latest released version
04:27 PM JT-Shop: plasmac might be what you need, I don't know enough about it to comment
04:29 PM roycroft: BUT it uses german IGBTs, and that makes a big difference
04:29 PM roycroft: btw, the blue, red, and yellow inverter welders are made in china these days
04:30 PM roycroft: the smaller units usually have a fairly low duty cycle, regardless of make
04:30 PM roycroft: for me that's fine
04:30 PM roycroft: i can live with 40% duty cycle for most projects
04:30 PM CaptHindsight: i got a WSME a few years ago since ALL the boards inside are on ebay for ~$100 or less
04:31 PM -!- #linuxcnc mode set to +v by ChanServ
04:31 PM roycroft: the 200a everlast mig welder is on sale for about the same price as the vulcan
04:31 PM CaptHindsight: yeah, they do rate them differently
04:31 PM roycroft: i would have to pay shipping on it though
04:31 PM roycroft: so that drives the price up
04:32 PM CaptHindsight: an uhmerican machine might say 200A at 100% duty cycle and 300A at 40% and call it their 200A model
04:32 PM roycroft: everlast have been around for a while, though, and have a good reputation both for product quality and repair
04:32 PM CaptHindsight: the Chinese would call it their 400A model with 10% duty cycle
04:32 PM roycroft: vulcan seems decent, but i have no idea how i'd get one of them repaired
04:33 PM CaptHindsight: extended warranty?
04:33 PM roycroft: well everlast comes with a 5 year warranty
04:33 PM CaptHindsight: swap-o-matic
04:33 PM roycroft: for hf you get to pay a lot more for an extended warranty
04:33 PM CaptHindsight: for the Vulcan
04:33 PM roycroft: now the vulcan costs more than the everlast
04:34 PM roycroft: and the vulcan is 170a @40% vs 200a @ 40% for the everlast
04:34 PM CaptHindsight: everlast come via freight
04:34 PM CaptHindsight: Vulcan is a few minute drive away
04:34 PM roycroft: yes, but the vulcan + extended warranty would cost more than everlast + shipping
04:34 PM roycroft: and if an everlast needs repair i just drop it off at a local airgas store and they handle it
04:35 PM roycroft: the nearest airgas store to me is closer than the nearest hf
04:35 PM CaptHindsight: how soon do you need it? I'd go with the everlast unless your rich aunt is waiting at the register with her AMEX platinum card out
04:35 PM CaptHindsight: someone stocks Everlast? Finally!
04:37 PM roycroft: i should probably hold out for the everlast
04:37 PM roycroft: if i'm honest, it's not a good time to buy a welder, since i'm about to spend $2k on a jointer
04:38 PM roycroft: but i have some projects coming up for which the lincoln mig welder is not well-suited
04:38 PM roycroft: when i saw the welder sale at hf i started thinking about getting a new one
04:38 PM roycroft: but it's probably best to stick weld the upcoming stuff and just keep what i have for now
04:38 PM roycroft: and i need to get going on the mill conversion soon
04:38 PM CaptHindsight: reward yourself with the easy to get repaired welder
04:39 PM roycroft: for which i think i have almost everthing, but that means probably a few hundred more dollars worth of stuff that i'll end up needing
04:39 PM roycroft: i don't weld all that often - repairs have never been an issue
04:39 PM roycroft: my everlast tig welder is a decade old and it's in like-new condition
04:40 PM CaptHindsight: Bitcoins are the Beenie Babies of the tech world
04:40 PM roycroft: that lincoln 120v mig welder i've had for probably 25 years, and all it has needed is consumables
04:40 PM roycroft: neither machine probably has more than 150 hours on it
04:50 PM Thorhian: roycroft: This is the kind of flooding power I am wanting.
04:50 PM Thorhian: https://youtu.be/XqZ39fCm8S8
05:06 PM JT-Shop: roycroft, what jointer are you getting?

05:11 PM roycroft: it's not the one i really want, but it's the one that i i can get before next year
05:11 PM roycroft: and it's close enough to what i want
05:12 PM roycroft: i'll be ok with it
05:17 PM htasta: maybe you wrote it wrong in the ini or wherever you defined that number? maybe your locale needs a , instead of a . ?
05:17 PM htasta: errorxyz

05:18 PM errorxyz: The comment a the bottom I have added later
05:18 PM roycroft: if you're pasting more than about 3-4 lines, please use a pastebin site, thank you very much
05:19 PM errorxyz: Oh ok thx :D
05:20 PM _unreal_: ok Just got my mag switches
05:20 PM _unreal_: lets see how long it takes me to get them wired up. mounted into my laser etcher
05:20 PM _unreal_: I'm guessing most of tonight
05:21 PM htasta: I'm guessing less than half of tonight :P
05:22 PM htasta: errorxyz: post a link to the config because the pasted text doesnt show the value giving the error at least I can't find a 0.5
05:23 PM errorxyz: htasta, first here, is the console output of linuxcnc: https://pastebin.com/hbJQV2sH
05:24 PM errorxyz: htasta Here is the Ini: https://pastebin.com/JUUHaTY4
05:24 PM htasta: #OFFSET_AV_RATIO = 0.5
05:25 PM htasta: the # at the start of the line means this line is a comment
05:25 PM errorxyz: Yes, it was uncommented before
05:25 PM htasta: you have to remove the # to activate the line
05:25 PM errorxyz: I have just switched around.
05:27 PM htasta: to me it reads like this belongs to section AXIS_Z and not JOINT_0
05:27 PM errorxyz: Thx did I didn't say it recently, but the main problem is the Material and Config tabs being empty with my ini and hal. When I use the original ini and hall, it those tabs are filled with usefull info. I have created a forum post
05:27 PM errorxyz: https://forum.linuxcnc.org/plasma-laser/41909-gmoccapy-plasmac-run-config-tabs-empty-exceptions-regarding-missing-handlers#202521
05:27 PM htasta: float(self.i.find('AXIS_Z', 'OFFSET_AV_RATIO'))) * 60
05:28 PM htasta: see, reading OFFSET_AV_RATIO in section AXIS_Z
05:28 PM htasta: but you put it in section JOINT_2
05:29 PM errorxyz: JOINT_2 is my Z axis, and as far as I understand it should be in this sectio
05:29 PM htasta: you also put max velocity and max accel again in JOINT_2
05:29 PM htasta: well the code disagrees with your understanding
05:29 PM htasta: and the code is king :D
05:30 PM NoGodDamnIdea: _unreal_, i tried the arduino solution today
05:31 PM htasta: errorxyz: did it work when put in AXIS_Z ?
05:32 PM errorxyz: damn you are righ about that Axis_Z ... it ended up in the wrong place
05:32 PM htasta: :D the code doesn't lie
05:34 PM errorxyz: WOW! that solved ALL the issues!!!
05:34 PM errorxyz: htasta your the man
05:34 PM htasta: nice
05:36 PM errorxyz: unbelievable that this little mistake also completely broke the run+config tabs, also also interrupted the plasma voltage transmission .. which I noticed works now
05:55 PM _unreal_: NoGodDamnIdea, cool
05:55 PM _unreal_: what direction did you take?
06:14 PM JT-Shop: for steppers max accel should be 25% more than accel
06:14 PM CaptHindsight: got a call about building a superprecision machine that nobody makes but it has to "be proven to have been made before" and requires proof in a peer reviewed publication
06:15 PM htasta: errorxyz: I have mine set 25% higher but I don't understand why it is needed. so I don't think I can help you there.
06:16 PM XXCoder: CaptHindsight: wtf
06:16 PM CaptHindsight: I'm trying to rent a time machine to see what i can do
06:17 PM JT-Shop: Santa may be able to help you with that
06:17 PM htasta: a super precise machine made for a scientific work would satisfy that requirement
06:18 PM htasta: nobody makes it and it has been made before and published
06:19 PM _unreal_: CaptHindsight, I'm NOT renting out the time machine
06:19 PM _unreal_: give it up
06:21 PM DaViruz: CaptHindsight: build two
06:32 PM CaptHindsight: nah, I'd just go back and kill Hitler
06:45 PM errorxyz: I'm german and I approve of this message
06:46 PM _unreal_: I'mm in the tropics and I dont care :)
06:47 PM _unreal_: freaking HOT too today
06:47 PM _unreal_: 81f
07:24 PM roycroft: i have some rather disturbing news, which is new to me at least
07:24 PM roycroft: shopvac have gone out of business
07:25 PM roycroft: and while that may not seem at first to be a big deal, they manufactured shop vacs for lots of other companies, and manufactured virtually all hoses/wands/other accessories for all the other brands
07:25 PM roycroft: i needed a 2-1/2" coupler, and i went to six stores, to find them all pretty much wiped out on all shopvac supplies
07:26 PM roycroft: my next visit will be to thingiverse, which might get me through the day
07:27 PM roycroft: and nothing there that will work, so i guess now i get to visit my cad software
07:31 PM flyback: https://www.youtube.com/watch?v=JMpXNxUQiMQ
07:32 PM flyback: BMCC
07:32 PM roycroft: aah, i just found a nicely designed one on thingivere
07:35 PM CaptHindsight: GreatStar Tools USA acquired ShopVac and has reopened the plant in Williamsport
07:36 PM CaptHindsight: even rehiring many of the same workers
07:38 PM roycroft: that's good news
07:38 PM roycroft: then the shortage will be temporary
07:39 PM roycroft: meanwhile, i'll print the part i need today
07:44 PM _unreal_: have to hire the same workers so they can learn how it was operated so they can fire them
07:44 PM _unreal_: :)
07:48 PM roycroft: i wish we had a capitalist economy in this country
07:49 PM roycroft: all these single-source monopolies screw everybody but their shareholders and execs
07:49 PM CaptHindsight: what do you have against crony capitalism?
07:50 PM roycroft: it is inherently corrupt
07:50 PM roycroft: and it is unamerican, btw
07:50 PM roycroft: it goes against everything we stand for as a country
07:51 PM CaptHindsight: nah, half the country wants you to have an authoritarian ruler, so this can't be true :)
07:52 PM roycroft: that's that half who are total idiots and aren't aware that what they "want" will have the opposite effect than the outcome they expect
07:52 PM CaptHindsight: they are even willing to sacrifice their income, freedom, health care etc for it
07:53 PM CaptHindsight: and don't you forget it!
07:53 PM roycroft: i have not printed petg for a while - i hope i remember the temps i use for it
07:53 PM CaptHindsight: i never said that they were smart
07:54 PM CaptHindsight: run some test pieces, you'll dial it back in again
07:55 PM roycroft: this part is going to take several hours to print
07:55 PM roycroft: i'll find out in the end if i set the temps right
07:55 PM roycroft: actually, i'll probably get a sense in just a few minutes, after the first few layers have printed
07:57 PM roycroft: but regarding crony capitalism
07:58 PM roycroft: i'm a fan of honesty and decency
07:58 PM roycroft: capitalism can be corrupt
07:58 PM roycroft: as well as socialism and other economic models
07:58 PM roycroft: it's not the model that's the problem
07:58 PM roycroft: it's the people working the model
08:09 PM CaptHindsight: well then we the people just don't care enough about changing the current system
08:11 PM CaptHindsight: lately it's been the ones who want it to be even worse making more noise
08:12 PM CaptHindsight: worse for most, and better for a few
08:15 PM CaptHindsight: roycroft: who is actively doing anything to combat the corruption?
08:17 PM CaptHindsight: roycroft: a few like yourself point it out, but who is organizing and actively working against corruption?
08:20 PM roycroft: not enough folks, unfortunately
08:21 PM CaptHindsight: roycroft: pm me a list or even news on this
08:22 PM roycroft: folks take their cheap soma and don't care about anything
08:22 PM roycroft: anyway, the print seems to be ok so far
08:23 PM roycroft: i could probably bump the temperature up 5 degrees and it would be better
08:23 PM roycroft: but it should be good enough for a shop vac part
08:23 PM CaptHindsight: I know that Biden, Schumer and Pelosi are mainly doing damage control right now
08:23 PM roycroft: that doesn't really matter
08:23 PM roycroft: both of our main political parties are pretty much the same
08:24 PM roycroft: i mean, one is way meaner and hateful than the other
08:24 PM roycroft: but they both work for the same people
08:24 PM roycroft: who are not us
08:24 PM CaptHindsight: I'm waiting to see some real action for the betterment of the avg person
08:25 PM roycroft: someone like senator sanders or senator warren would have gotten closer to that than the mainstream party would
08:25 PM roycroft: i actually think president biden may surprise us
08:26 PM roycroft: time will tell
08:26 PM CaptHindsight: when will i read about something similar in the US? https://grapevine.is/news/2018/02/07/36-bankers-96-years-in-jail/
08:27 PM roycroft: we don't need to put the bankers in jail
08:27 PM BitEvil is now known as SpeedEvil
08:27 PM roycroft: we need to take control of the economy away from wall street
08:27 PM roycroft: and think about main street
08:27 PM CaptHindsight: when?
08:27 PM roycroft: the sooner the better
08:27 PM CaptHindsight: it's no secret what is going on
08:28 PM CaptHindsight: but nothing gets done about it
08:28 PM roycroft: i'm doing something right now
08:28 PM CaptHindsight: last real pressure that made a little change was during Nixon
08:28 PM roycroft: i'm printing a part that i need at home
08:29 PM roycroft: using filament made by a small company based in indiana who make their own products here in the usa
08:29 PM roycroft: i should have done this before going out and looking for the part made by the big monopoly who outsource all their work to china
08:30 PM CaptHindsight: got us out of Vietnam but also really upset those for the war, they learned how do deal with protests here
08:30 PM roycroft: i think that blm will be more lasting than folks think right now
08:30 PM CaptHindsight: it would be nice
08:32 PM roycroft: i have this annoying personality trait of being optimistic
08:32 PM CaptHindsight: lots of could, would, should but little actually done
08:32 PM roycroft: but trying to put that aside and look at things objectively, i think we've made a lot of progress in my lifetime
08:33 PM CaptHindsight: i understand
08:33 PM roycroft: we've a long way to go before we achieve star trek times
08:33 PM roycroft: but we're way way better than the before times
08:33 PM CaptHindsight: two steps ahead, and one step back
08:34 PM roycroft: sure
08:34 PM roycroft: and in the short term that doesn't seem like much
08:34 PM roycroft: but over time it makes for a lot of progress
08:34 PM CaptHindsight: last 30+ years have been a real threat to education and democracy
08:34 PM roycroft: as optimistic as i am, i firmly believe that we have to overcome tribalism before we can take a quantum step forward
08:35 PM roycroft: and that's going to be difficult to do
08:35 PM CaptHindsight: tribalism and religion
08:35 PM roycroft: they are one and the same, essentially
08:35 PM CaptHindsight: ancient superstitions
08:36 PM XXCoder: capt years of cuts on education
08:36 PM XXCoder: expecially in "red" states
08:36 PM roycroft: the decline of religion in western society is the cause of increased political triablism, i believe
08:36 PM roycroft: politics is the new religion
08:36 PM CaptHindsight: lack of education leaves a vacuum
08:36 PM CaptHindsight: especially history
08:36 PM roycroft: which is why i've become increasingly apolitical
08:36 PM XXCoder: yep and it vacuums up junk
08:37 PM CaptHindsight: roycroft: you're not alone
08:38 PM CaptHindsight: the dems always keep Bernie down and those similar
08:38 PM XXCoder: we have right and more right
08:38 PM XXCoder: bernie is centerist
08:38 PM XXCoder: ie too far left
08:39 PM CaptHindsight: not many here want progress
08:39 PM roycroft: https://roycroft.us/Coupler.jpeg
08:39 PM CaptHindsight: well they might but they think that going backwards is progress
08:39 PM roycroft: i think that will probably turn out ok
08:39 PM roycroft: it's a little more goobery than i would like
08:40 PM roycroft: hence my saying that upping the temperature 5 degrees would probably be good
08:40 PM roycroft: but it should be a functional part in the end
08:41 PM roycroft: i made a new table for my 2x72 grinder last weekend, so i can sand long wooden pieces horizontally and have good support for them
08:41 PM roycroft: and i need dust collection if i'm going to sand wood in the fabrication shop
08:41 PM CaptHindsight: so what do you do with a nation with half the people that think pedophile space aliens in pizza shops are the real threat?
08:41 PM roycroft: i have that all done, but i need this coupler to connect the dust collection duct to the shop vac hose
08:42 PM CaptHindsight: it's not even a good comic book plot
08:42 PM XXCoder: yeah
08:42 PM roycroft: capthindsight: you remain calm and patient and try to slowly teach them not that they are wrong, but that their enemies are not as bad as they think
08:42 PM roycroft: there is common ground
08:43 PM roycroft: but most folks don't seem to see it these days
08:43 PM roycroft: wedge issues need to be pushed aside
08:44 PM roycroft: what do the "right" and the "left" both want?
08:44 PM roycroft: they want to live comfortable, interesting lives
08:44 PM CaptHindsight: an outsider might say we are pretty primitive and ignorant, lacking the ability to think critically or too lazy
08:44 PM roycroft: they want to be able to provide for their children
08:44 PM roycroft: both tribes want that
08:45 PM CaptHindsight: sure, common ground, provide for your family...
08:45 PM roycroft: so that should be the focus
08:45 PM CaptHindsight: food, shelter, jobs
08:46 PM CaptHindsight: I've had these same discussions all over the world for 50+ years
08:46 PM roycroft: as much as the "right" make immigration, gay rights, and abortion their wedge issues, the "left" make gun control and religion their wedge issues
08:46 PM CaptHindsight: problems in the middle east, Asia, Africa, South America and now North
08:46 PM roycroft: i'm one who most would consider a "leftist"
08:47 PM CaptHindsight: people all have the same basic issues
08:47 PM roycroft: but wokeness pisses me off to no end, and i understand why the "right" get so incensed by it
08:47 PM roycroft: we've lost our collective perspetive as a people
08:48 PM roycroft: perspective
08:48 PM roycroft: we need to regain it
08:48 PM CaptHindsight: the propaganda here has been right out of 1930's Germany to divide
08:48 PM roycroft: the problem is that wedge issues are what drives political fundraising
08:49 PM CaptHindsight: if so many voters are shallow
08:49 PM roycroft: a campaign reform constitutional amendment would help a lot
08:49 PM roycroft: and it's my primary concern with the way our government dysfunctions
08:50 PM roycroft: total public finance of elections - no private donations/lobbying
08:50 PM roycroft: an exception to the 1st amemendment making it illegal for poltiical candidates to lie
08:50 PM CaptHindsight: sure but half of congress will not vote for that
08:50 PM roycroft: more than half
08:50 PM roycroft: i've been waiting all my life for it
08:50 PM CaptHindsight: it's not a secret what the solutions are
08:51 PM roycroft: and it hasn't happened, and i don't think it will
08:51 PM roycroft: that does not mean it's not the right thing to do though
08:51 PM CaptHindsight: the secret seems to be who is going to organize a movement to get this done
08:51 PM roycroft: it means we're not going to do what's right
08:52 PM CaptHindsight: we have moved passed breads and circuses
08:52 PM roycroft: i don't think of myself as a "liberal", but if anyone thinks that accountability for what one says and does is a "liberal" concept, then i'll proclaim to be guilty as charged
08:53 PM CaptHindsight: the masses aren't just distracted, they are nearly incapable of thinking rationally
08:54 PM roycroft: it's all that soma
08:55 PM roycroft: which often comes disguised as things like amazon prime and netflix
08:55 PM CaptHindsight: very well trained consumers and fans of their political leaders
08:57 PM CaptHindsight: think as i say or you are against us was used heavily during Cheney/Bush
08:57 PM CaptHindsight: why using labels like liberals is such a trigger now
08:58 PM CaptHindsight: it's not thinking, it just a reflex now
08:58 PM XXCoder: roycroft: germany and 1984
08:58 PM XXCoder: remember when trump literally indirectly quoted 1984 most essental rule
08:58 PM CaptHindsight: on our team or not on our team
08:58 PM XXCoder: "what you see, and what you hear is not happening"
08:59 PM CaptHindsight: if you're not on our team you are the enemy and should be ignored and attacked
08:59 PM CaptHindsight: it is cult like as well
08:59 PM CaptHindsight: XXCoder: yes, it progressed into that clearly
08:59 PM XXCoder: yep
08:59 PM CaptHindsight: don't believe your own eyes and ears
09:00 PM CaptHindsight: I will tell you WHAT to think
09:02 PM CaptHindsight: I get attacked for pointing this out
09:03 PM roycroft: i think it is time to fire up the barbie and get ready to make dinner
09:03 PM roycroft: that's what i think
09:04 PM CaptHindsight: how this ends up often gets ugly, not peaceful
09:05 PM CaptHindsight: if the US doesn't fix itself, someone else will ...
09:05 PM jdh: that's because only our side knows the real truth. You just know what you hear from the lying media
09:05 PM CaptHindsight: yeah clever
09:06 PM jdh: or something.
09:06 PM CaptHindsight: if you can't reason, you just pick a side... or you might be too busy working 3 jobs to survive
09:08 PM CaptHindsight: if you missed a few thousand years of human history what is to be done with you?
09:10 PM CaptHindsight: when the Romans had a gas shortage what did the peasants do to run their chariots?
09:10 PM CaptHindsight: all the airports shut down
09:10 PM CaptHindsight: why we had the "dark ages"
09:13 PM CaptHindsight: it wasn't until Martin Luther and L. Davinci got together to create a renaissance did things get progressive again
09:14 PM roycroft: not everyone is going to be able to reason, for various reasons
09:14 PM roycroft: so we should make it clear which sides are which, and make it easy to pick the right side
09:14 PM XXCoder: big lie sucks :(
09:14 PM CaptHindsight: the earth was no longer flat and the french could start a political and industrial revolution
09:14 PM roycroft: which is what the campaign reform amendment would facilitate
09:15 PM roycroft: so if i'm honest, i was lazy
09:15 PM CaptHindsight: leading to the invention of the Gin Mill
09:15 PM roycroft: this spool of petg has been sitting on the printer for at least a month
09:15 PM roycroft: i don't remember exactly when i last printed with it
09:15 PM roycroft: but i had not put it away in a vacuum sealed bag
09:15 PM roycroft: and i did not dry it out today before printing
09:16 PM roycroft: this is the middle of the rainy season here, and the humidity has been really high for months
09:16 PM roycroft: it's still printing ok though
09:16 PM CaptHindsight: roycroft: who could see what would come after Citizens United? :p
09:16 PM roycroft: petg seems more resliant than other filaments to hydration
09:16 PM roycroft: i saw citizen's united coming
09:16 PM CaptHindsight: we had spring last week and snow again yesterday
09:17 PM roycroft: i've been advocating for a campaign finance amendment for decades
09:18 PM CaptHindsight: the USA got progressive in the 1930's to the 60's
09:18 PM roycroft: well, in the late 19th century/early 20th century, then in the '30s, then in the '60s
09:18 PM CaptHindsight: having the only real industrial capabilities left also helped a lot after 1945
09:18 PM roycroft: we're actually as a people more progressive than ever
09:19 PM roycroft: but the old white men who don't represent the people are digging in more than ever
09:19 PM CaptHindsight: yeah by the 60's they started clawing their way back
09:20 PM CaptHindsight: anti- intellectual, education, union, social programs etc
09:20 PM CaptHindsight: and it worked
09:23 PM CaptHindsight: I don't to go church, monster truck rallies, listen the hate radio or watch Fox much...
09:25 PM XXCoder: roy yeah its more resistant than abs or pla
09:25 PM XXCoder: erm not pla but nylon
09:25 PM XXCoder: pla is most resistant to grabbing water but evenually it will
09:28 PM CaptHindsight: thermopolymer filaments are all porous and have an affinity to collect water in these pores
09:28 PM CaptHindsight: why pellets are always baked before use
09:29 PM CaptHindsight: filaments can be as well
09:29 PM CaptHindsight: and annealing after printing makes them much stronger
09:30 PM CaptHindsight: oh the heated build chamber patent expired
09:30 PM CaptHindsight: this will also help make better FDM/FFF prints
09:33 PM CaptHindsight: https://omnexus.specialchem.com/polymer-properties/properties/water-absorption-24-hours
09:33 PM CaptHindsight: sorry for the tech link vs something reprappy :)
09:35 PM CaptHindsight: one could read through this and similar site and then find thermoplastics suitable for FFF prints
09:35 PM CaptHindsight: it's like magic
09:36 PM CaptHindsight: compare physical properties, choose wisely and make suitable filaments
09:56 PM CaptHindsight: PLA is not in the above chart https://www.researchgate.net/figure/Water-absorption-curves-of-pure-PLA-and-PLA-ENR-blends_fig5_291287113
09:57 PM CaptHindsight: so here it is ^^

10:30 PM _unreal_: damn I'm tired
10:31 PM _unreal_: so at this point. I'm 90% done with the optical to mag. limit switches conversion
10:31 PM _unreal_: got to fix a trace I had cut on one of my small pcb's that is a custom breakout
