01:20 AM mrec: ok wrong expectations ..
01:39 AM Loetmichel: Mornin' *giggle* 2" new snow and a RWD car... FUUUN! I doubt the Anti skid control lamp went off for the entire commute to work. :)
03:33 AM mrec: okay the limit switches seem to work, but I'm still able to drive against the switches and it keeps tripping and gives me a limit switch tripped is there a way to avoid that?
03:39 AM rs[m]: mrec: configure soft limits?
05:13 AM JT-Cave: morning
05:14 AM XXCoder: hey
05:14 AM JT-Cave: 18,7°F in the coop
05:21 AM XXCoder: cold
05:44 AM JT-Cave: Effective Jan 1, 2021, value added tax (VAT) must be collected for all goods entering the United Kingdom (UK).
05:44 AM JT-Cave: what a pia
05:44 AM JT-Cave: so much for shipping to UK
05:47 AM XXCoder: yeah
06:16 AM mrec: rs[m]: got it just set the limit switches outside of the "milling" area
06:16 AM mrec: limit switches + homing switches are the same in my case.
06:16 AM mrec: it's a small toy mill
06:17 AM gregcnc: are they not already set at the "limits", not within the usable area?
06:17 AM JT-Cave: that is normal
06:18 AM mrec: eg. milling area -120 - + 120 limit switches are at 125
06:18 AM mrec: the limit switch is at 125
06:19 AM JT-Cave: usually it's 0-240
06:19 AM JT-Cave: and home is 0
06:20 AM mrec: and limit switch at -5?
06:20 AM Tom_L: morning
06:20 AM gregcnc: the actual values don't matter
06:20 AM JT-Cave: yea your home offset should move the axis off the switch
06:20 AM JT-Cave: yea the numbers can be anything that works
06:21 AM mrec: if it would be 0 then it would trip at 0 and pop up an error
06:21 AM JT-Cave: no, use a home offset when you home so 0 is not on top of the switch
06:22 AM gregcnc: make the switch outside the soft limits
06:22 AM JT-Cave: you will know when you get it right by trying to jog to the ends of travel after homing
06:55 AM JT-Cave: hmm one of the pullets laid an egg already this morning and it's before dawn
07:20 AM gregcnc: oh. i didn't know that about UK VAT. USPS site make zero mention.
07:33 AM JT-Cave: got that from stamps.com
07:34 AM JT-Cave: gregcnc, https://paste.ubuntu.com/p/wzywSC7vgr/
07:35 AM JT-Cave: well that's another country I no longer ship to
07:35 AM mrec: limits just work fine now. I also increased the homing search speed and it's comfortable now.
07:42 AM jdh]: do chickens jsut start laying eggs whenver? or is there some mating trigger?
07:44 AM JT-Cave: no mating is required only they must be mature enough... heritage breeds it's usually 6 months of age some breeds like my Cinnamon Queens they start laying at 5 months of age
07:47 AM jdh]: seems like a lot of physiological stress with a completely uncertain reproductive success?
07:48 AM gregcnc: I guess I can still sell through Ebay and they can handle the VAT much like they collect and pay state taxes
08:22 AM JT-Cave: https://gnipsel.com/images/7i96/7i96-PC.png
08:22 AM * JT-Cave heads to the shower
08:22 AM beachbumpete1: Morning folks!
08:27 AM beachbumpete1: https://imgur.com/gallery/cnCWvoV
08:27 AM beachbumpete1: my first big print after the electronics upgrade
08:27 AM beachbumpete1: :)
08:43 AM mrec: is there a hotkey to switch from continuous to eg. 0.5 mm? I think I saw someone in a video pressing something but I couldn't see what that was and maybe he set up custom keys ..
08:58 AM gregcnc: axis? http://linuxcnc.org/docs/2.7/html/gui/axis.html#_keyboard_controls
09:07 AM mrec: maybe i or c
10:53 AM unterhaus_: I guess that guy on ebay isn't going to take my offer on the monoprice printer
10:54 AM unterhaus_: Hasn't sold any since last night though
10:56 AM roycroft: i've found that a lot of ebay sellers have a best offer option but never respond to offers
10:56 AM gregcnc: or counter a nickel less
10:56 AM roycroft: my speculation is that some sellers use that option just as a gauge to see what folks are willing to pay
10:56 AM unterhaus_: this guy was taking offers
10:56 AM unterhaus_: on a different auction
10:56 AM roycroft: yeah, i've gotten those as well
10:57 AM roycroft: i bought some power receptacles last month
10:57 AM roycroft: i needed four of them
10:57 AM unterhaus_: he had a number of black printers, which were cheaper and he took offers
10:57 AM roycroft: the seller i originally went to had a really good price, but severely inflated shipping
10:57 AM unterhaus_: he has 15 white printers, which are priced higher
10:57 AM roycroft: iirc he wanted $9.95 for the receptacles, with $11 shipping
10:58 AM roycroft: i offered something like $6 each for 4 of them
10:58 AM roycroft: figuring that he would put them all in the same box and savel most of the shipping cost
10:58 AM unterhaus_: I would never assume that
10:58 AM roycroft: he came countered with slightly less than the original price
10:59 AM gregcnc: i note that in the offer so they understand why i'm making the offer
10:59 AM unterhaus_: but still 11 each shipping?
10:59 AM gregcnc: it even works sometimes
11:00 AM unterhaus_: sounds like you're lucky he didn't take your offer
11:00 AM roycroft: i responded that he would be saving on the combined hsipping, and he responded with a tirade of expletives about "low-ball" buyers
11:00 AM gregcnc: some people are gouging, some have no idea how to handle ebay shipping sttings
11:00 AM roycroft: i don't understand why people still use shipping as a profit center on ebay
11:00 AM roycroft: in the olden days ebay did not charge seller fees on shipping
11:00 AM unterhaus_: only thing I can see is it makes the cost look less
11:00 AM roycroft: and people were selling things for $1, with $49.99 shipping
11:01 AM unterhaus_: even in the old days, it cost people sales
11:01 AM gregcnc: if you search by price it includes shipping
11:01 AM roycroft: ebay caught on to that many many years ago
11:01 AM roycroft: and started charging fees on shipping
11:01 AM gregcnc: some people think shipping actually costs them that much time and material
11:01 AM gregcnc: and maybe it does
11:01 AM roycroft: well they're idiots if they do
11:01 AM unterhaus_: I used to look for auctions like that, often saved money because people were offended by the shipping and wouldn't bid
11:01 AM roycroft: i won't say that i don't profit at all on shipping
11:01 AM gregcnc: buy any cutting tools lately? $15 for a 1lb box
11:01 AM roycroft: i do actually make a tiny amount of money on it
11:02 AM roycroft: i actually probably lose on it still, actually
11:02 AM roycroft: i charge my out of pocket cost for any packaging/padding materials
11:02 AM unterhaus_: $11 shipping is nothing, but $44 is ridiculous
11:02 AM roycroft: and i let ebay's shipping calculator determine the shipping cost
11:02 AM roycroft: but i use their shipping service, and there's always a discount, on the shipping cost
11:03 AM roycroft: so i make a dollar or two on shipping
11:03 AM unterhaus_: ebay's calculator has been awful for me
11:03 AM roycroft: but i do not factor my time into it at all
11:03 AM unterhaus_: it used to work
11:03 AM roycroft: i just bought some hide glue
11:03 AM unterhaus_: I admit I haven't sold anything recently because it's so unpleasant all around
11:03 AM roycroft: $11.99 for the glue
11:03 AM roycroft: $9.95 for shipping for 1 lb, which fits in a small priority mail box
11:04 AM roycroft: it costs $4.50 to ship
11:04 AM gregcnc: no
11:04 AM unterhaus_: where did you get hide glue?
11:04 AM roycroft: but total cost to me is $22
11:04 AM gregcnc: priority small flat rate is 7.65 at discount, 8.50 retail
11:04 AM roycroft: and that's still a good price
11:04 AM roycroft: if i went to woodcraft i'd pay $30 for 1 lb of hide glue
11:05 AM roycroft: it is that much?
11:05 AM roycroft: it's gone way up then
11:05 AM unterhaus_: I got some with my glue pot, I have never been able to make it work, need more practice
11:05 AM gregcnc: that the other issue prices are way up
11:05 AM roycroft: what kind of problems are you having with it, underhaus_?
11:05 AM unterhaus_: it doesn't stick
11:06 AM gregcnc: 4.50 for priority, maybe 10 years ago
11:06 AM roycroft: that's odd
11:06 AM roycroft: this his how i prepare it:
11:06 AM unterhaus_: that's what I thought
11:06 AM roycroft: i add water to the granules
11:06 AM roycroft: in a jar
11:06 AM roycroft: i let it sit at room temperature overnight
11:06 AM roycroft: the next day i heat it up in the glue pot
11:06 AM roycroft: stir it in occasionally
11:07 AM roycroft: when it's up to temperature i remove it, and put it in the refrigerator overnight
11:07 AM roycroft: the next day i heat it up again and it's ready to use
11:07 AM unterhaus_: okay, I thought you could just heat it up
11:07 AM roycroft: i use a glue pot
11:07 AM roycroft: but in the inner pot, instead of just putting the glue in i put the jar in the pot and add another water jacket
11:08 AM roycroft: that way i don't ever hav to clean the glue pot
11:08 AM roycroft: also, if you're using a jar or a non-copper glue pot, put a small piece of copper in the bottom of the jar/pot
11:09 AM roycroft: copper is anti-microbial, and if you have a bit of copper in the glue that will keep it from molding
11:09 AM roycroft: and if you store it in the fridge, you can reheat it many times
11:09 AM unterhaus_: I have one of these https://www.amazon.com/Hot-Glue-Pot-Combo-Electric/dp/B00K0WJUYU
11:09 AM roycroft: if you don't do that it will only keep for a couple days before it will mold and start smelling horrible
11:10 AM roycroft: oh, nice
11:10 AM roycroft: the copper in the brass might work well enough
11:10 AM unterhaus_: yeah, sometimes I think I should have gotten the lee valley
11:10 AM unterhaus_: I have kept it in the fridge forever without it stinking, so it must work the same way
11:11 AM unterhaus_: I'll have to try your prep method
11:11 AM roycroft: maybe you have some crappy glue
11:11 AM roycroft: trh this:
11:11 AM roycroft: https://www.ebay.com/itm//301838485797
11:11 AM unterhaus_: I thought about that
11:11 AM roycroft: milligan & higgins is really good hide glue
11:12 AM roycroft: and they clean/filter it really well, and sterilize it
11:12 AM roycroft: it does not mold as easily as most hide glues
11:12 AM unterhaus_: I got the glue with the pot
11:12 AM roycroft: i would recommend 192 gram strength when starting out with hide glue
11:12 AM roycroft: once you get used to using it you probably want some stronger glue, like 241 gram strength
11:13 AM unterhaus_: does the stronger stuff setup faster?
11:13 AM roycroft: the higher the gram strength, the stronger the bond, but the lower the open time
11:13 AM roycroft: yes
11:13 AM roycroft: for super strong joints you can get 350 or so gram strength, but you'll have an open time of a minute at most
11:14 AM roycroft: and if you're working in a cold shop you'll have an open time of about zero
11:14 AM unterhaus_: that might be nice for guitar tops
11:14 AM roycroft: yes, the high gram strengths are often used for instruments
11:14 AM roycroft: i'm not a luthier, but the glue strength also affects the tone quality
11:14 AM roycroft: so if you're making instruments you might research that
11:15 AM unterhaus_: that's what I was thinking, luthiers are very open about things like that
11:16 AM unterhaus_: although I saw someone that works at Martin being coy about some process they use
11:17 AM roycroft: i think it's worth investing $20 on some high quality glue to see if that fixes your problem
11:17 AM unterhaus_: probably
11:17 AM roycroft: also, don't mix it too thinly
11:18 AM roycroft: standard strength is a 1;1 mix of glue granules and water, by weight
11:18 AM roycroft: so less water by volume than glue
11:18 AM roycroft: i weigh it, because it's a lot easier to weigh accurately than to measure volume accurately
11:19 AM roycroft: when it's at the proper temperature - 60-62c - it should have the consistency of yellow glue
11:19 AM unterhaus_: it's possible that's my problem
11:19 AM roycroft: folks do mix it and heat it quickly and get decent results
11:20 AM roycroft: soaking for 30 minutes, heat to temp once
11:20 AM unterhaus_: I need to get a good scale
11:20 AM roycroft: but i find i get more consistent results with the longer soaking time, and heating it twice
11:20 AM roycroft: if you mix it in a jar, and add a little piece of copper to the jar, it will keep for weeks and weeks in the refrigerator
11:21 AM roycroft: and if you can vacuuum seal the remaining granules they'll keep for a year or two
11:22 AM roycroft: does the glue you got with the glue pot smell bad when you heat it?
11:22 AM roycroft: or smell much at all?
11:24 AM roycroft: oh wow
11:24 AM roycroft: sheldon adelson has died
11:27 AM unterhaus_: saw that about Adelson. I always wondered why those old billionaires care so much about taxes when they are going to die with billions anyway
11:27 AM unterhaus_: Pay your taxes, live in a nicer place, still be incredibly wealthy. Where's the downside?
11:28 AM unterhaus_: My glue don't stink. Or stick :)
11:28 AM roycroft: adelson spent $200 million trying to buy the recent election
11:28 AM unterhaus_: It's possible I over-diluted it
11:28 AM roycroft: he did not die with all his billions
11:28 AM Thorhian: Oh boy, election talk.
11:28 AM unterhaus_: They spend so much, it's like they can't do math
11:28 AM roycroft: if you overdiluted that would be the problem
11:29 AM roycroft: no worries, thorian, it was a one-off statement
11:29 AM roycroft: i don't intend to get into a discussion about it
11:29 AM unterhaus_: not election talk, we're bashing the recently deceased
11:29 AM Thorhian: I'm so done with all of the crap going on overall, I don't need it in the linuxcnc IRC chat lol. How's it going roycroft?
11:29 AM roycroft: unterhaus_: i think that the volumetric ratio is about 1 part granules to 3/4 part water
11:30 AM roycroft: it's going ok, thanks
11:30 AM roycroft: i'm hanging in, getting stuff done
11:30 AM roycroft: waiting for class 1a to get vaccinated
11:30 AM roycroft: i'm in class 1b
11:30 AM Thorhian: Are you in school?
11:31 AM roycroft: 1a is medical workers, first responders, and people in assisted living centers
11:31 AM Thorhian: Ah, that makes sense.
11:31 AM roycroft: i am not in school
11:31 AM Thorhian: Just haven't been watching MSM so not familiar with the specific terms like that. Not surprising they are prioritized though.
11:32 AM unterhaus_: it's state by state at this point
11:32 AM roycroft: yes, i'm talking about how my state are doing things
11:32 AM unterhaus_: Pennsylvania says if you aren't sure when you'll be vaccinated, don't ask
11:32 AM roycroft: class 1b are people over 65 and people at high risk
11:33 AM roycroft: i had pneumonia a few years ago that left me with a big of lung scarring
11:33 AM roycroft: that puts me at high risk
11:33 AM unterhaus_: I think I'm probably high risk, but not high enough to get vaccinated
11:33 AM roycroft: so i should be able to get in the queue as soon as the 1a folks have their go
11:33 AM Thorhian: I'm in Idaho lol. Young and I may have had Covid along with the rest of my household, thankfully super mild even for the high risk members of my house.
11:33 AM roycroft: i'm hoping by the end of the month or so
11:34 AM roycroft: my boss just went to idaho
11:34 AM roycroft: i refuse to go into the office when it's been occupied in the last 8 hours
11:34 AM roycroft: my boss also refuses to wear a mask
11:34 AM roycroft: so it's a very unsafe environment
11:34 AM unterhaus_: our lab has a 1 person at a time policy
11:35 AM unterhaus_: which is strict, but sensible
11:35 AM roycroft: we just need to get moving with the vaccinations
11:35 AM unterhaus_: yes, I'm glad my wife got it already, physician
11:35 AM Thorhian: It's nice and cold here :) I wear a mask when I go to places and actually wash my hands often lol. I don't feel like accidentally lending a hand in killing my grandmother.
11:35 AM roycroft: hopefully, once the new administration take over, the utter incompetence and bumbling will end, and the feds will actually start shipping the vaccines in quantity
11:36 AM roycroft: we're over 2 weeks behind schedule here in oregon
11:36 AM gregcnc: where is it, is it piling up in warehouses?
11:36 AM unterhaus_: it takes coordination, the vials have enough vaccine for 10 people
11:36 AM roycroft: in part due to the disasterous distrubution by the feds
11:36 AM unterhaus_: so some is being wasted every day
11:36 AM roycroft: and in part because when the first doses arrived in oregon, many of our state health officials were on vacation
11:36 AM roycroft: i'm pissed off at both the state and the feds
11:37 AM unterhaus_: the states aren't handling it well, New York is a cluster
11:37 AM roycroft: it's being held in cold storage by the manufacturers
11:37 AM Thorhian: Lol New York is a joke, along with the big cities in California. So glad I moved out of Cali.
11:37 AM roycroft: and that's the other problem
11:37 AM unterhaus_: Cuomo is fining places for not giving it to the right people
11:37 AM roycroft: the vials have more than the rated 5 doses
11:38 AM roycroft: but the syringes the feds are shipping with them are wasteful
11:38 AM gregcnc: cuomo wants to open NY now
11:38 AM roycroft: they don't empty completely, so folks administering the vaccines have to draw more into the syringe than they inject
11:38 AM Thorhian: Lol really?
11:38 AM roycroft: and waste a bunch of it
11:38 AM roycroft: there are syringes that are much less wasteful
11:39 AM roycroft: but that's not what are being shipped
11:39 AM roycroft: i don't know what the dosage is, but if, for example, it's 10ml, you have to fill the syringe with like 14ml to be able to inject 10ml
11:40 AM roycroft: those are totally made up numbers, i'm just using them to make the point
11:40 AM Thorhian: My question is whether or not people can shed the virus after being vaccinated.
11:40 AM roycroft: we don't know for sure
11:40 AM roycroft: but it's assumed we do
11:40 AM Thorhian: Great.
11:40 AM roycroft: so we're going to have to mask and distance, even after being vaccinated, until we reach herd immunity
11:41 AM roycroft: the sooner we get on with it the sooner it will be over
11:41 AM roycroft: the protesters and anti-maskers are harming their own cause by resisting
11:42 AM Thorhian: Even with herd immunity, if it still sheds it still spreads though, pontentially mutating even more?
11:42 AM roycroft: we're bordering on political talk again, even though this is a health issue, not a political issue
11:42 AM roycroft: yes, but so far the way it's mutated that's not a big deal
11:42 AM roycroft: from what we know as of now, the mutations are such that our t cells are still ready for the mutants
11:43 AM roycroft: it's not like the seasonal flu
11:43 AM roycroft: where the mutations require a different vaccine
11:43 AM roycroft: so far it's not
11:43 AM Thorhian: My concern is that it will still stick around even though no one gets sick, perpetually still around.
11:43 AM roycroft: it could mutate in a different way at any time
11:43 AM roycroft: sure
11:44 AM roycroft: people just need to get past conflating a healt crisis with politics
11:45 AM roycroft: and then we can take a sensible approach to ending the pandemic and keeping people healthy
11:45 AM gregcnc: when do the salad mandates come?
11:45 AM roycroft: i don't know what that means, so i can't answer
11:45 AM roycroft: i'm really excited that we're using mrna vaccines
11:45 AM Thorhian: AKA, Covid would never be dead. It could mutate, and require another vaccine. If only there was a way to stop it from shedding entirely while making people immune.
11:46 AM roycroft: it's a breakthrough that could help prevent a lot of diseases
11:46 AM roycroft: and may help with curing cancers and the like
11:46 AM roycroft: thorian: it doesn't matter if a virus is floating about if everyone is immune to it
11:47 AM roycroft: as far as mutating, that's going to happen no matter what
11:48 AM Thorhian: I guess Pandora's Box has been opened over in China already, so no going back *shrug*.
11:48 AM roycroft: anyway
11:48 AM roycroft: a good quality hide glue is almost odorless
11:48 AM roycroft: so if yours does not smell bad when heated it's probably decent stuff
11:48 AM roycroft: i would suspect overdilution
11:49 AM roycroft: the ratio does not need to be precise, but the more repeatable the mix, the more repeatable the results
11:49 AM roycroft: try another batch at 1 part granules by volume to 3/4 part water by volume
11:49 AM roycroft: do the long soak and the double heat like i suggested earlier
11:49 AM roycroft: and see if you get better results
11:50 AM roycroft: to test, take two jointed boards, apply glue to the edge of one of them, and rub the other back and forth along it
11:50 AM Thorhian: I have been soldering wires to a parallel port connector that plugs into my servo drive for my spindle. I also have some resistors to act as voltage dividers to drive the motor correctly finally.
11:50 AM roycroft: it should start sticking in a few seconds
11:51 AM Thorhian: So maybe today I will finally be able to control my spindle with LinuxCNC finally.
11:51 AM unterhaus_: thanks roycroft, you have given me something to try anyway
11:51 AM roycroft: 192 gram strength is going to be weaker than the strength of most woods, so you shoul might be able to split the joint without damaging the wood
11:52 AM roycroft: 241 gram strength is close to the strength of many woods, so you may not be able to break at the joint
11:52 AM unterhaus_: the joints I did really let go easily
11:52 AM roycroft: of course, you can always heat the joint or moisten it to break it
11:52 AM unterhaus_: I also probably should have heated the wood a little
11:52 AM roycroft: the glue you got is probably 192 gram strength
11:52 AM unterhaus_: it's never particularly warm in my shop
11:53 AM roycroft: since it's the easiest for beginners to use
11:53 AM roycroft: it's also good for veneering, or any other case where you need a decent amount of open time because you're gluing up a large area or multiple joints at the same time
11:54 AM unterhaus_: the advantages for instruments are pretty big. And it sticks to itself
11:54 AM roycroft: it also takes stains/dyes
11:54 AM roycroft: and it sets up quickly
11:55 AM roycroft: there are so many advantages to hide glue
11:55 AM roycroft: just don't use it on your adirondack chairs
12:40 PM beachbumpete1: Any of you guys in here have experience with taking scanner point clouds and creating .STL files and then solid models like STP etc from them?
12:46 PM Tom_L: what did you want to know?
12:47 PM Tom_L: my kid did that for a while but i dunno what software they used
12:47 PM beachbumpete1: I am trying to determine a good process to take our point cloud data and turn it into solid models so we can create cabinet and trim options for it.
12:48 PM Tom_L: one sec, i'll ask what he used
12:48 PM beachbumpete1: We use recap Pro to import the point cloud data and it used to allow this but now they changed it and it is no longer supported. Now I am using a combination of meshmixer and meshlab to take the point cloud data to a useable place but its comlplex
12:52 PM roycroft: unterhaus_: are you still about?
12:52 PM Tom_L: https://www.innovmetric.com/products/polyworks-inspector
12:52 PM Tom_L: beachbumpete1,
12:53 PM Tom_L: he thinks that's what they used to convert the point cloud
12:54 PM beachbumpete1: ah it almost looks like an ad for CMM equipment
12:54 PM beachbumpete1: we have a 3D lidar scanner made by leica
12:54 PM beachbumpete1: we are using it a fair bit lately and the larger projects customers are asking for models of the spaces we scan
12:55 PM beachbumpete1: Id like to get ahead of this which is why I asked in here because I know you guys know everything ;)
12:55 PM Tom_L: they had all sort of scanners where he was
12:55 PM Tom_L: for small very accurate to large rooms or airplane frames, wings etc
12:56 PM Tom_L: https://www.hexagonmi.com/products/software/software-for-laser-tracker-systems/polyworksreg
12:57 PM Tom_L: hexagon may be their product
12:57 PM unterhaus_: roycroft here
12:59 PM Tom_L: beachbumpete1, the first link may have been their inspection tool
12:59 PM Tom_L: hexagon looks more like what you're after
12:59 PM beachbumpete1: watched their video and it shows a guy taking measurements with various tools but nothing about the software
01:03 PM beachbumpete1: interesting..
01:04 PM Tom_L: they were reverse engineering an F18 air frame when he left
01:04 PM Tom_L: complete
01:05 PM beachbumpete1: looks more manufacturing/metal based product/software
01:05 PM Tom_L: they scanned their lab i know
01:06 PM Tom_L: i don't think the scanners care what they scan :)
01:06 PM beachbumpete1: I found a link to a fellow that showed how to take the point cloud data out of Recap Pro and export it as an .pts file. Then he brought it into meshlab and was able to use the cloud to create the mesh
01:06 PM Tom_L: if it's shiny they powder it first
01:06 PM beachbumpete1: I would not think so either
01:07 PM beachbumpete1: yes we already learned that after trying to scan a cylinder head for a friend
01:07 PM Tom_L: hh
01:07 PM Tom_L: he
01:07 PM Tom_L: heh
01:07 PM beachbumpete1: you have to puff it with powder
01:07 PM Tom_L: i quit
01:07 PM beachbumpete1: ?
01:07 PM Tom_L: typos
01:07 PM beachbumpete1: did I say something wrong?
01:07 PM Tom_L: just my fat fingers
01:08 PM beachbumpete1: ah
01:08 PM beachbumpete1: there are a LOT of tools inside meshlab most of which are foreign to me at this point that allow manipulation and repair of the mesh/cloud etc.
01:08 PM beachbumpete1: Just was wondering what the pro's may be using for this.
01:09 PM Tom_L: i'm sure it carries a pro price too
01:10 PM Tom_L: you still doing custom cabinets?
01:10 PM roycroft: yes, the "pro" tools are likely several thousands to tens of thousands of dollars
01:10 PM roycroft: and likely work very well
01:14 PM roycroft: aah, my last 2021 wall calendar has finally arrived
01:14 PM roycroft: the one that goes in my office
01:16 PM beachbumpete1: yeah we do custom cabinetry and millwork and also metal and even SLA printed models for a variety of customers
01:22 PM Tom_L: roycroft, woodworking porn?
01:23 PM roycroft: huh?
01:25 PM Tom_L: your calendar...
01:26 PM roycroft: oh
01:26 PM roycroft: this one is actually a nice one - it's historical maps of scotland
01:26 PM Tom_L: cool
01:28 PM roycroft: january is a map of fife, and the firth of forth, from the jacobean times
01:42 PM unterhaus_: I did some work on a cmm, hate to say how much that cost the company
01:43 PM unterhaus_: guessing about $200k, custom software and interfacing the hardware
01:44 PM unterhaus_: between me and another person
01:44 PM roycroft: unterhaus_: a thought occured to me
01:44 PM roycroft: have you checked the temperature of your glue pot?
01:45 PM roycroft: if you get hide glue too hot - around 75-80c for most varieties, the proteins break down and you no longer have glue, just a mess
01:46 PM roycroft: the water bath needs to be around 70 degrees to keep the glue at 60
01:46 PM roycroft: but if it's much hotter than that it would cause the exact problem you're experiencing
01:52 PM Nick001-Shop: /msg NickServ identify nick73
01:53 PM unterhaus_: roycroft, I had thought about temperature. I also used water from a teapot to speed up the initial softening. Probably a mistake
01:54 PM unterhaus_: correction, in the glue pot
01:54 PM unterhaus_: glue pot doesn't warm up the water very fast on its own
01:58 PM roycroft: yes, that as a mistake
01:58 PM roycroft: oh, wait
01:58 PM roycroft: you used warm water in the water jacket part?
01:58 PM unterhaus_: yes
01:58 PM roycroft: or you used it to dissolve the glue?
01:59 PM roycroft: ok
01:59 PM roycroft: that doesn't matter
01:59 PM roycroft: you need to use cold water to mix with the glue itself though
01:59 PM unterhaus_: in the pot, pretty sure. But I have to use your method just to make sure
01:59 PM roycroft: cold water to cold glue granules
01:59 PM roycroft: once the glue is hot, if you need to thin it, add hot water
01:59 PM roycroft: but the initial mixing must be done with cold water
02:00 PM roycroft: get a thermometer to put in the glue pot
02:00 PM roycroft: so you can monitor the temperature of the glue
02:00 PM unterhaus_: you can't with mine
02:00 PM unterhaus_: I suppose I could drill a hole
02:00 PM roycroft: i'm taking about putting it in the glue part
02:00 PM roycroft: not the water jacket part
02:00 PM unterhaus_: okay
02:01 PM roycroft: i have a hold heet glue pot
02:01 PM unterhaus_: yeah, I need to tighten up my process
02:01 PM roycroft: the water jacket part is not accessible in that either
02:02 PM roycroft: if it was as weak as you say it was i suspect it got too hot more than that it was too thin
02:02 PM roycroft: unless you put like 3 parts water to 1 part glue it should have a fair amount of strength
02:03 PM roycroft: i'm one for good process control, but hide glue doesn't have to be that precise
02:03 PM roycroft: as long as it does not get too hot
02:03 PM unterhaus_: I was following a luthier on youtube, I think the viscosity was very similar to his
02:03 PM roycroft: once the protein breaks down you no longer have long protein strands
02:03 PM roycroft: you have amino acis soup
02:03 PM roycroft: acid
02:03 PM roycroft: which is not glue
02:04 PM roycroft: when you warm up a protein the chemical bonds will relax and it will get stretchy and rubbery
02:05 PM roycroft: but it will remain intact, and when it cools again it will revert to its original, more rigid shape
02:06 PM roycroft: but when you heat it past a certain point the bonds between the amino acids will break, and when you cool it off they will not rejoin
02:09 PM unterhaus_: thanks for all your advice, I will try to follow it before i forget everything
02:10 PM unterhaus_: If I get my delta sigma to run, I want to use lcnc so I can use servos
02:11 PM unterhaus_: Looks like JT used lcnc for his 3d printer
02:16 PM roycroft: the rain is letting up a little
02:17 PM roycroft: we may not have flooding tonight after all
02:20 PM enleth: why do all those fucking morons designing those machines use a square milled notch as a key in cast iron gibs
02:20 PM enleth: another one just broke off
02:20 PM enleth: in a bridgeport knee gib
02:21 PM enleth: how hard it is to figure out that it's a shit idea when this keeps happening for decades prior
02:23 PM unterhaus_: is it a real bridgeport?
02:24 PM enleth: yes, it is, series 1 rigid ram
02:24 PM enleth: knee gib is most likely identical to manual bridgeports
02:25 PM unterhaus_: haven't looked at my knee gibs, series II rigid ram
02:25 PM unterhaus_: box ways
02:25 PM enleth: this is the most braindead thing I've ever seen in machine tool design
02:26 PM unterhaus_: in their defense, it worked for 40 years, right?
02:26 PM enleth: all it takes is milling that notch with a fucking bullnose endmill to eliminate stress risers
02:26 PM unterhaus_: I assume they used a saw, but same thing, maybe easier
02:27 PM enleth: I mean the notch the adjustment screw collar sits in
02:27 PM enleth: the dumb thing likes to snap off
02:27 PM unterhaus_: I'm pretty sure I know what you are talking about, I have seen BP dovetail gibs
02:28 PM enleth: it's definitely milles, I don't see how one wpuld use a saw to cut it
02:28 PM enleth: *milled
02:28 PM unterhaus_: problem on my machine is the air assist on the knee is long dead
02:28 PM unterhaus_: it's a slot 90 degrees to the length of the gib, right?
02:29 PM enleth: yes, a slot, the word I was actually looking fpr
02:30 PM enleth: it's a damn stress riser in the most critical part of the gib
02:30 PM enleth: in a brittle material
02:30 PM enleth: in a feature known to fail since 1850s if I were to take a guess
02:31 PM enleth: fucking morons
02:31 PM unterhaus_: the ones I am seeing with a google image search could be made either way, so I'm guessing slitting saw
02:31 PM unterhaus_: good news is there are tons of them for sale
02:31 PM enleth: ah, that sort of saw
02:31 PM enleth: bad news is, they're mostly in the US
02:32 PM enleth: and I'm not 100% sure the CNC iron takes the same gib
02:32 PM unterhaus_: as a USian, I would like to apologize for Connecticut, they have always been a problem
02:32 PM unterhaus_: they also seem to have been scraped
02:32 PM enleth: this, too
02:33 PM unterhaus_: although it might be oil retention scraping
02:33 PM enleth: so I can't just pop a new one in
02:34 PM unterhaus_: I'm glad the gib in my lathe has a bolt in the end for adjustment
02:34 PM unterhaus_: does your mill use the knee for z?
02:35 PM unterhaus_: mine has a ballscrew on the spindle
02:38 PM enleth: mine does too, so it's just table height adjustment
02:39 PM enleth: eh, fuck the guy who designed this, and everything he stood for
02:40 PM enleth: looks like I'll have to take half of this dumb machine apart, again
02:42 PM enleth: because someone was too dumb and cheap to design it properly
02:50 PM unterhaus_: I wouldn't want to have to do that with mine, I think the knee and x and y tables weigh over 2000 pounds
02:50 PM unterhaus_: I'm dreading even jacking the knee up so I can fix the air assist
02:54 PM perry_j1987: afternoon guys
03:01 PM beachbumpete1: Tom_L: Thanks for the tips today man
03:06 PM andypugh: Interesting machining challenge.
03:07 PM andypugh: I have a broken harmonic actuator: https://photos.app.goo.gl/p1qZAPyRpxLhfgi29
03:07 PM andypugh: It is famously impossible to make your own, so I am tempted to try.
03:08 PM andypugh: This is the tooth profile, about 1mm pitch.
03:08 PM andypugh: https://photos.app.goo.gl/ssCp2MDJhTFwhayi8
03:10 PM andypugh: I think I can make a D-bit cutter for the bottom and lower curve, but I am not so sure how to do the concave part of the cutter,
03:10 PM andypugh: syyl: Any thoughts? Other than “don’t try”
03:25 PM unterhaus_: Andy, it didn't break on a tooth, did it?
03:26 PM unterhaus_: I saw the fracture pic, but I forget
03:26 PM gregcnc: looks like it broke everywhere
03:26 PM unterhaus_: it propagated, as fatigue cracks do
03:29 PM unterhaus_: this pic isn't conclusive at all, but it looks to me like it started at the bend https://photos.app.goo.gl/p3SL2Bwv2b9yd5XJ9
03:30 PM unterhaus_: the reason I say that is there is cracking past the place where it goes up to the teeth
03:33 PM unterhaus_: I guess they do flex the toothed section though
03:35 PM unterhaus_: if the toothed section was just a metal belt, it wouldn't be a problem to flex it. but it wouldn't stay in place or transmit power
03:36 PM unterhaus_: without special capabilities, the problem we have is connecting it to the external transmission
03:37 PM unterhaus_: Making that connection in a flexible way may be possible. Thinking of crossed beam flexures maybe
03:40 PM unterhaus_: cross leaf flexure or just cross flexure. Sometimes realized with rods
03:40 PM unterhaus_: the leaf has an advantage that it can transmit quite a bit of force along the width of the leaf
03:43 PM Tom_L: beachbumpete1, np
03:43 PM Tom_L: andypugh, take a bit to a grind shop?
03:44 PM Tom_L: man that thing is really toast ehh
03:44 PM unterhaus_: the most expensive part failed, as was intended
03:46 PM andypugh: Tom_L: You mean pay someone to do something because it’s too difficult for me? Are you mad!
03:46 PM unterhaus_: this must happen to all of them eventually
03:46 PM sync: unterhaus_: it doesn't work without flexing the coke can
03:46 PM Tom_L: andypugh, approach it as 2 halves
03:46 PM andypugh: Yes, it’s the expected failure mode, I would say
03:46 PM Tom_L: not one whole
03:46 PM unterhaus_: it's only the wall of the coke can that has to flex
03:47 PM unterhaus_: the problem is connecting that to the part that transmits power
03:47 PM unterhaus_: and the bend is a weak spot because they press it out of flat sheet
03:47 PM unterhaus_: that's actually the part that we can't do, not the gear
03:48 PM andypugh: There is a design with two internal splines. The flex engages with both of them, but they have different numbers of teeth.
03:48 PM andypugh: unterhaus_: No, definitely not pressed. That Hex is part of the same part, and is screwed/glued into the output flange.
03:49 PM andypugh: It might be friction welded. Or forged.
03:50 PM gregcnc: can you get parts?
03:50 PM unterhaus_: okay, the cups on my robot sure seem to be one piece
03:52 PM andypugh: gregcnc: They won’t even talk to me. I asked.
03:52 PM andypugh: unterhaus_: They are one piece. But I don’t think that they are pressed. Forged or sintered is entirely possible.
03:53 PM sync: andypugh: I guess you could use a diaform to profile a grinding wheel and then grind the teeth?
03:54 PM andypugh: If I had a Diaform (I have used one)
03:55 PM andypugh: Hmm… I could CNC dress a grinding wheel.
03:56 PM andypugh: I would need to have a very good idea what the geometry of my dressing diamond was, though.
03:59 PM unterhaus_: yours must have a lot more clearance than the robot harmonic drives, must be higher power
04:00 PM andypugh: It’s a much coarser pitch than the other HD that I have.
04:00 PM unterhaus_: you have to be looking at mine to see it has teeth
04:00 PM andypugh: But I think it’s only 200W. It’s an FHA-17C
04:00 PM Tom_L: https://www.youtube.com/watch?v=9DwqN1pEkVg
04:00 PM Tom_L: this was one i saw a while back
04:02 PM andypugh: Making a rubbish harmonic drive is so easy that I have never bothered :-)
04:02 PM unterhaus_: the problem with fixing one is that the id is fairly important
04:02 PM andypugh: unterhaus_: And the OD. And both really hard to measure.
04:03 PM unterhaus_: fixturing
04:03 PM Tom_L: might be ok for making cheap robots
04:03 PM perry_j1987: there we go got some mounts 3d printing for these caps and a mount for the parport breakout board for insulated standoffs and such
04:04 PM andypugh: unterhaus_: One of the issues: https://www.youtube.com/watch?v=5nW3nJhBHL0
04:04 PM Tom_L: andypugh, what sort of steel would that be made from?
04:04 PM andypugh: I was thinking something like P20
04:05 PM Tom_L: https://www.mathsisfun.com/geometry/ellipse-perimeter.html
04:06 PM unterhaus_: in its relaxed state, the cup is round
04:07 PM sync: andypugh: yeah, I thought about that too and I'm not entirely sure how to do that (cnc dressing)
04:08 PM sync: I guess you could use a nickel bond diamond wheel to dress an aluminium oxide wheel
04:08 PM sync: and if your diamond wheel is straight with sharp corners you only need to know the diameter and the width of the dressing wheel
04:10 PM andypugh: Making a gear-grinding hob is probably relatively easy. But this is not an involute tooth form.
04:10 PM Tom_L: https://www.harmonicdrive.net/_hd/content/documents/CSG-2UK_GearUnits.pdf
04:10 PM Tom_L: might have some tooth profile info
04:11 PM andypugh: Diaforms use a specifically shaped single-point diamond and a matching stylus on the pantograph.
04:11 PM andypugh: Tom_L: There is some, evan a drawing.
04:12 PM unterhaus_: I'm going to go out on a limb and say every one of this particular model breaks
04:12 PM unterhaus_: the cup is too short
04:13 PM andypugh: Tom_L: Drawing here: https://www.harmonicdrive.net/technology
04:13 PM andypugh: unterhaus_: I have a second-hand FHA25 on my rotary that did a full working life and is still working for me.
04:14 PM unterhaus_: I would think about making a spacer and making the cup deeper
04:15 PM unterhaus_: of course, that wouldn't work on mine so it's probably a silly thought
05:02 PM perry_j1987: hows it going guys
05:06 PM roycroft: um, yeah
05:06 PM roycroft: tool costs 27.5 euros
05:06 PM roycroft: weighs 1kg
05:06 PM roycroft: shipping from germany - 101 euros
05:06 PM * roycroft passes
05:07 PM roycroft: the company forgot the fine print
05:07 PM roycroft: they say "we ship to usa"
05:07 PM roycroft: but the fine print that omitted is "but we don't like to"
05:07 PM Tom_L: get one from china instead
05:07 PM Tom_L: they will probably ship for free
05:07 PM roycroft: china does not make that tool
05:07 PM roycroft: i would not want one made in china anyway
05:08 PM roycroft: it's something that i'll be holding in my hand and looking at on a regular basis
05:08 PM Tom_L: i _was_ kidding
05:08 PM roycroft: yes, i know
05:09 PM roycroft: i can get it from canadia for US$59.50 + shipping
05:09 PM roycroft: which is too much, but way less than the german price
05:09 PM Tom_L: canada post is all but non exhistent
05:10 PM roycroft: it's from lee valley
05:10 PM roycroft: they ship from new york and reno
05:10 PM roycroft: but they're canadian
05:10 PM roycroft: ooh, and they have free shipping atm
05:10 PM roycroft: that works
05:10 PM * Tom_L waits for the 'catch'
05:11 PM roycroft: it's lee valley
05:11 PM roycroft: no catch
05:11 PM roycroft: they're a good outfit
05:13 PM roycroft: ok, there is a 'catch'
05:13 PM Tom_L: hahaha
05:13 PM roycroft: i haven't bought anything from them for a while
05:13 PM roycroft: so now i have to see if there's anything else i want
05:13 PM roycroft: :)
05:14 PM roycroft: they offer free shipping on orders >$30
05:14 PM Tom_L: it will end up costing the same from germany
05:14 PM roycroft: i already qualify for that
05:14 PM roycroft: but i often want something that's <$30
05:14 PM Tom_L: but you may end up with more 'stuff'
05:14 PM roycroft: yeah, but i'll have more stuff
05:14 PM XXCoder: sync
05:14 PM roycroft: so it's a win-ouch situatin
05:14 PM roycroft: situation
05:14 PM XXCoder: do they sell food also?
05:14 PM roycroft: not that i'm aware of
05:15 PM roycroft: i am still on a diet anyway
05:15 PM roycroft: i do not need poutain
05:15 PM XXCoder: grab something that'll be gone sometime. thats how I go over 25 usd at amazon
05:15 PM roycroft: i could use a few more file handles, actually
05:15 PM roycroft: and they're really cheap, so i can't justify an order just for file handles
05:16 PM roycroft: i'll have to go take inventory - almost all my files have handles, but i know there are a few that don't
05:16 PM roycroft: and i really like the ones from lee valley - they're the twist-on type, not the pound-on type
05:20 PM roycroft: well, i must have executed that cunning plan already, because not only do all my files have handles, i have a half dozen spare handles
05:28 PM Tom_L: get more files
05:28 PM roycroft: i need to do that
05:28 PM roycroft: but not from lee valley
05:34 PM perry_j1987: going through the VFD's datasheet now making notes
05:34 PM perry_j1987: got all my parts ready to go now i think
05:34 PM perry_j1987: well... waiting on buss bars still
05:35 PM perry_j1987: getting close to seeing this lathe fire up
05:44 PM JT-Cave: whew long day... one down 9 more to build and install...
05:47 PM Tom_L: first one work?
05:47 PM Tom_L: now just a mini assembly line..
05:49 PM JT-Cave: yea got all the undocumented features worked out and all the steps sorted out
05:49 PM JT-Cave: I thought I took a video but must not have...
05:49 PM JT-Cave: just waiting on all the components to arrive
05:51 PM JT-Cave: my Mesa order is arriving Monday so should be all stocked up again
05:53 PM XXCoder: nice
05:53 PM XXCoder: i hope to be able to order one evenually, to work with rpi4 or orange pu
05:54 PM JT-Cave: for once all the chickens went to the perch without being scolded
05:55 PM roycroft: my problem, which is a good one to have, is that i have almost all the <$100 tools that i need, so it's hard to find things to pad out orders
05:55 PM JT-Cave: order some for me
05:55 PM perry_j1987: lol
05:55 PM perry_j1987: i seen that coming
05:58 PM JT-Cave: well roycroft has purchased things for me in the past that I could not find...
05:59 PM roycroft: i just ordered the one item
05:59 PM roycroft: it's too much work finding other things to add to the order
06:00 PM JT-Cave: I got the bench top for my mobile clamp/sanding cart done just need to install the wagon vise I made
06:01 PM JT-Cave: yeah I just faced that with an automation direct order where I forgot $28 worth of legend plates on a $6,500 order
06:04 PM unterhaus_: I am trying to decide if I can make something like a B&D workmate that will be useful
06:05 PM JT-Cave: I used mine the other day to hold my C punch
06:05 PM roycroft: i had a pair of workmates that i used to haul around on job sites for decades
06:05 PM roycroft: they were awesome for tht
06:05 PM roycroft: they got left out in the rain one winter, and by spring time they were useless
06:05 PM roycroft: and i don't do site work much any more, so i never replaced them
06:06 PM JT-Cave: yea particle board sorta tops are a bit touchy
06:07 PM roycroft: yup
06:07 PM perry_j1987: hmm im looking at implementing at-speed from this vfd
06:07 PM roycroft: but i could have made new tops pretty easily
06:07 PM JT-Cave: https://www.greenlee.com/us/en/driver-punch-hyd-1-2x1-1731-1731?w=2&c=161&b=86&r=30&p=1&l=4&v=c
06:07 PM roycroft: the frames were rusted though, and i was not going to mess with that
06:07 PM JT-Cave: I have that one with a foot pump
06:07 PM perry_j1987: looks like it has transistor that pulls low when at speed
06:09 PM JT-Cave: https://www.greenlee.com/us/en/pumpfoot-hyd-1725-m3-1725
06:09 PM JT-Cave: that's the foot pump
06:12 PM JT-Cave: 6pm do you know where your chickens are?
06:13 PM perry_j1987: wait nm i got an encoder on the spindle
06:13 PM perry_j1987: lol
06:19 PM _unreal_: do any of you know what those filler things are called for aluminum extrusion
06:19 PM _unreal_: so you can put wires in a side
06:20 PM _unreal_: and encapsulate it
06:21 PM perry_j1987: t-slot covers
06:21 PM perry_j1987: thingiverse.com prob has some options
06:22 PM CaptHindsight: https://www.greenleestore.com/products/greenlee-1725-hydraulic-foot-pump on sale for $775
06:23 PM CaptHindsight: wow $1k off, https://www.greenleestore.com/products/greenlee-1731-1-shot-k-o-driver
06:26 PM perry_j1987: http://support.technocnc.com/pdf/0229_LC_and_Lathe_Board-Callouts-Connectors.pdf what do you gather the 24v line on the encoder plugs is for
06:26 PM perry_j1987: also 5v
06:26 PM perry_j1987: was told they operate at 5v
06:31 PM _unreal_: https://www.amazon.com/gp/product/B08HV57Y5M/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
06:31 PM _unreal_: that is my machine
06:31 PM _unreal_: trying to solve for what type of Tcover I need
06:31 PM W1N9Zr0: could be to power relays that are part of the e-stop loop
06:32 PM perry_j1987: oh i think they are running the limit switches with 24v
06:32 PM perry_j1987: what is estop loop
06:33 PM W1N9Zr0: emergency stop. if a cover is open, encoder is not operating properly, or something similar, the machine won't run
06:33 PM _unreal_: the extrusion is 20x40MM
06:34 PM perry_j1987: _unreal_ 5 or 6mm slot
06:34 PM perry_j1987: https://www.thingiverse.com/thing:2034738
06:35 PM _unreal_: 6mm
06:35 PM perry_j1987: https://www.thingiverse.com/thing:2747857
06:35 PM perry_j1987: lots of options
06:36 PM perry_j1987: you have a 3d printer?
06:36 PM perry_j1987: https://amzn.to/2MTKA2l
06:36 PM perry_j1987: you can fit few wires in still with the rubbery kind
06:37 PM _unreal_: laser etcher
06:37 PM _unreal_: I'm just trying to find a source for t slot covers
06:37 PM _unreal_: amazon does not have them
06:37 PM _unreal_: not prime anways
06:37 PM perry_j1987: just sent you link on amazon to them
06:37 PM perry_j1987: if you have a 3d printer you can print your own with those thingiverse links i gave too
06:39 PM _unreal_: ebay has non as well
06:39 PM _unreal_: I dont have a 3d printer
06:40 PM perry_j1987: https://amzn.to/2MTKA2l
06:48 PM _unreal_: cover not a filler
06:49 PM perry_j1987: i said you can still fit a few wires under these styles
06:49 PM perry_j1987: depends what gauge and how much your wanting
06:50 PM _unreal_: going to take up half the channel
06:51 PM _unreal_: no good
06:51 PM perry_j1987: it bulges up
06:53 PM CaptHindsight: do you sand, polish and paint them?
07:04 PM _unreal_: according to the online chat https://www.grainger.com/product/80-20-T-Slot-Cover-16U368
07:04 PM _unreal_: that one will work for me
07:05 PM _unreal_: so I'm going to order a bunch of that
07:21 PM perry_j1987: yep should work
07:25 PM perry_j1987: you should get a 3d printer
07:25 PM perry_j1987: then you could make it any color you want
07:25 PM CaptHindsight: who? Me?
07:25 PM perry_j1987: _unreal_
07:25 PM CaptHindsight: ah
07:26 PM perry_j1987: im about to head over to the shop and start poking around on this lathe
07:26 PM perry_j1987: http://support.technocnc.com/pdf/0229_LC_and_Lathe_Board-Callouts-Connectors.pdf trying to make sense of the encoder plugs
07:32 PM _unreal_: dont have the money currently
07:32 PM _unreal_: unless I win the power ball or mega millions
07:32 PM _unreal_: do any of you have any interest in a CSI MODEL 404B PHOTOTEACH
08:08 PM roycroft: my obsessive attention to detail has come through again
08:09 PM roycroft: i had a paint mixed up years ago to paint the undersides of wooden cabinets/machinery stands/etc.
08:09 PM perry_j1987: uh oh
08:09 PM roycroft: it's a light grey with a tinge of green
08:09 PM roycroft: i went to paint the underside of my bandsaw stand today
08:09 PM roycroft: i found that the paint had dried up because it's old
08:09 PM roycroft: but i found some grey deck paint
08:10 PM roycroft: i ended up going to the paint store and getting some of the correct color mixed up
08:10 PM roycroft: once i assemble the band saw stand nobody will ever see tht surface
08:10 PM unterhaus_: well the monoprice guy accepted my offer. What filament should I get?
08:10 PM roycroft: but it would bug me that it's a different color than all the rest
08:10 PM roycroft: filament for what?
08:11 PM unterhaus_: XXCoder you here?
08:11 PM XXCoder: just got back lol yeah
08:12 PM roycroft: what are you going to be printing?
08:12 PM XXCoder: congats unterhaus_
08:14 PM unterhaus_: what kind of filament should I get for it?
08:14 PM roycroft: we don't know until you tell us what you're going to print
08:16 PM roycroft: if you're just going to experiment then i would recommend starting with pla
08:17 PM XXCoder: atomic or maybe Paramount 3D
08:17 PM unterhaus_: I'm planning on messing up a batch of prints
08:17 PM roycroft: it's very forgiving, prints at low temperature, it is plant based and biodegradable, so no harm to the environment
08:17 PM unterhaus_: XX has the same printer
08:17 PM roycroft: and yes, i would recommend atomic filament
08:17 PM XXCoder: my atomic reels is 4 years though dont know if he changed but i doubt he did
08:17 PM roycroft: it's very consistent and high quality, made in usa, and available in a wide variety of colors
08:18 PM roycroft: whatever printer you just bought (and i'm not familiar with it), throw away the filament that comes with it
08:18 PM roycroft: don't even bother using it
08:19 PM unterhaus_: it's used, off of ebay
08:19 PM XXCoder: roy yeah. one that come with shit one i bought tried to kill me
08:19 PM roycroft: imo, trying to dial in a printer with shite filament is counterproductive
08:19 PM XXCoder: mine come with one LOL
08:19 PM XXCoder: looks like orginial too. so should be good quality but im not using it anyway
08:20 PM roycroft: i just got an email from atomic filament today
08:20 PM roycroft: some filament that's been on my list for a while is finally back in stock
08:20 PM XXCoder: nice
08:27 PM roycroft: but now i'm not sure if i need it
08:27 PM XXCoder: i want to try nylon but mp cat do nylon.
08:27 PM XXCoder: cant
08:27 PM roycroft: the stuff i am talking about is nylon
08:27 PM roycroft: but the part i was going to print with it i ended up making by hand out of aluminium in the meantime
08:27 PM roycroft: atomic are very good about notifying folks when product is in stock
08:27 PM roycroft: i like that
08:27 PM roycroft: but more than that, i like the quality and consistency of their filaments
08:27 PM roycroft: with them, pla is pla is pla
08:27 PM roycroft: it does not matter what color it is
08:27 PM roycroft: or what batch you get
08:27 PM roycroft: it's a very consistent size, always prints at the exact same temperature
08:27 PM roycroft: behaves the same
08:35 PM perry_j1987: plan to turn a spool into test cubes
08:36 PM perry_j1987: you'll have these weird little boats all over the house in no time too heh
08:51 PM _unreal_: arg....
08:51 PM _unreal_: dealing with wiring
08:51 PM _unreal_: I have these nice nema17 motors that have encoders on them
08:51 PM _unreal_: so I'm running encoder cable as well
08:51 PM _unreal_: WAY over kill
08:52 PM _unreal_: but would be nice to have the the option for feed back
09:17 PM roycroft: i have never printed a boaty
09:17 PM roycroft: does that make me a bad person?
09:17 PM XXCoder: i recently printed one
09:17 PM XXCoder: it was very high quality
09:18 PM roycroft: but does it float?
09:19 PM XXCoder: theres printable kit you can print to make it float properly
09:19 PM roycroft: if it floats, it's a witch!
09:20 PM XXCoder: if it dont, it drowns and is a witch!
09:23 PM W1N9Zr0: i've acquired these odd looking drill bits, anyone know what the notched shank is for? https://i.imgur.com/AJ5UOGt.jpg
09:24 PM W1N9Zr0: (they're 1/4" bits for scale)
09:34 PM roycroft: those drills are bit odd looking, but those kinds of flats are often on pilot drills for things like hole saw mandrels, although i've never seen any exactly like that
09:42 PM W1N9Zr0: ah, good call! gargle images shows something similar for "hole saw pilot drill" https://www.mactools.com/Images/780x780zoom/HS8535C.jpg
10:02 PM perry_j1987: curious about your theory roycroft about floating
10:03 PM perry_j1987: must be made of wood because wood floats then?
10:03 PM perry_j1987: but ducks float in water too
10:04 PM perry_j1987: monty python had some good stuff heh
10:46 PM unterhaus: the funniest part of that sequence was when she weighed less than the duck
10:46 PM XXCoder: "he got better"
10:47 PM unterhaus: so much of it was great, "and that my leige is how we know the earth is banana shaped"
10:49 PM unterhaus: they ran out of energy at the end of the movie though
10:50 PM unterhaus: spoiler alert, them getting arrested was mildly amusing
10:50 PM XXCoder: yeah
10:50 PM XXCoder: i fairly suspect they either ran out of funding, or couldnt think of a good ending
10:52 PM XXCoder: WOW
10:52 PM XXCoder: https://www.thingiverse.com/thing:2199356/files
10:52 PM XXCoder: thats awesome
10:52 PM Tom_L: perry_j1987, ice floats
10:53 PM unterhaus: I was looking for cross flexures on thingiverse and was somewhat disappointed
10:53 PM unterhaus: there was one
10:54 PM Tom_L: what about grabcad?
10:54 PM unterhaus: I saw one at a conference, but I guess they didn't post it online. It was a bellows flexure with cross bars at the end
10:57 PM XXCoder: https://www.thingiverse.com/thing:4690959/ awesome, im printing em soon]
10:58 PM Tom_L: machine one instead
10:58 PM Tom_L: anybody can print one
10:58 PM XXCoder: no machine able to do that :P
10:58 PM XXCoder: just had idea
10:59 PM XXCoder: make it double ended, like that puzzle bolt
10:59 PM Tom_L: print one and send it to me :)
10:59 PM XXCoder: hidden tap inside, but it would have to exactly align. i guess make double ended, tread and lock them together, then mill both ways threads
11:00 PM XXCoder: then seperate and insert both "nuts"
11:00 PM XXCoder: nah dont think printer can do hidden thing, due to having to precisely align
11:00 PM XXCoder: you can do it. i double dog dare you ;)
11:01 PM Tom_L: i don't have anything to make one with
11:01 PM XXCoder: drat
11:01 PM unterhaus: there are probably some puzzles that can only be made by 3d printing
11:01 PM Tom_L: no doubt
11:01 PM XXCoder: theres rotating rings. its possible in machinist methods, but not as easily
11:03 PM XXCoder: picture this, its 3 shells sphere, but cut away leaving middle section
11:03 PM XXCoder: rings cant get out
11:03 PM unterhaus: place I work part time has this, I'm going to print one when I figure out which end is up https://www.thingiverse.com/thing:4052526
11:03 PM Tom_L: that should be simple
11:04 PM XXCoder: very nice make https://www.thingiverse.com/make:885424
11:04 PM XXCoder: guy somehow made the inside both ways version
11:05 PM unterhaus: what's so 2-way about it?
11:05 PM XXCoder: look at golden nut
11:08 PM unterhaus: the nuts are backwards from each other, right?
11:08 PM XXCoder: other 2 yeah
11:08 PM XXCoder: golden one is both ways
11:08 PM XXCoder: i wonder if that means you could change mind on screw into bolt
11:09 PM unterhaus: golden nut brings up urban dictionary :)
