12:24 AM * Bleepshop ponders how to remove the stuck impeller from a blower that needs new bearings.
12:32 AM XXCoder: got a puller?
01:43 AM Deejay: moin
02:09 AM Loetmichel: MUHAHA... Nurse just twtittered: Patient wakes up after a surgery. "well, when can i walk again with the new knee?" Every nurse un the room: O_O ... Patient smirking: "... Yeah, i know, new hip." :)
02:25 AM randy: morning
02:53 AM -!- #linuxcnc mode set to +v by ChanServ
05:06 AM Tom_L: morning
05:06 AM Tom_L: 10°F
05:08 AM Tom_L: at least the wind died down here
05:09 AM JT-Cave: nws says it's N 18 mph here but I've not looked
06:48 AM unterhaus: they delayed trash day because of the snow and of course it's windy today
06:49 AM unterhaus: It's supposed to be -18.8889C on Saturday morning
06:49 AM unterhaus: that's probably -18.88888888888889
06:50 AM unterhaus: supposed to warm up on tuesday so it can snow
07:13 AM JT-Cave: wind chill -3°F at the moment
07:24 AM Tom_L: same here
07:25 AM Tom_L: 7°F actual
07:49 AM unterhaus: I'm tempted to get the igauging dro for my table saw. Not sure why
07:54 AM JT-Cave: hmm finally got a delivery date on the sorby chuck saturday
07:56 AM JT-Cave: for the fence?
08:03 AM unterhaus: yeah, it's only $60, what could go wrong
08:44 AM roycroft: it's my friday!
08:57 AM Alicrow-phone: Welp. Looks like the mill is gonna use a rotary phase converter. The static phase converter we got from H&W didn't do shit.
08:59 AM JT-Shop: they are super easy to make a self starting rpc
08:59 AM Alicrow-phone: Our manual mill and lathe are both using VFDs, but they make a real high-pitched whine, and there's not much point in the VFD speed control when it's a variable speed head, anyway.
08:59 AM JT-Shop: it's Saturday for me! I'm not going anywhere in this cold
09:01 AM Alicrow-phone: We ordered an RPC from American Rotary. Was a lot cheaper than I had expected.
09:26 AM JT-Cave: I think that's where I got my 20hp motor from
09:29 AM roycroft: vfds tend to whine a lot
10:09 AM unterhaus: msft doesn't want to install win 11 on my 5 year old computer. They promise there will be no updates. I thought they had updates to protect themselves
10:24 AM unterhaus: I just wired my lathe for ethernet. The production guys must have cursed at the engineers a lot for the way they ran the conduit.
10:37 AM JT-Shop: some guy wanted to know if I wanted to trade the psi chuck for some turning tools lol
10:52 AM roycroft: are they decent tools, or are they harbor freight specials?
10:53 AM JT-Shop: he didn't say
10:53 AM roycroft: decent turning tools are expensive
10:53 AM roycroft: it might be worth finding out what he has
10:53 AM roycroft: even if you don't need them, if the deal is good enough you could make the trade then flip them
10:54 AM roycroft: but there's a good chance he started with some cheap tools, got better ones, and now is trying to get rid of the cheap ones
11:12 AM perry_j1987: so that z axis i got for this 6040
11:12 AM perry_j1987: has a shot bearing
11:13 AM perry_j1987: going to do some slight modifications to put double length bearings in there
11:20 AM unterhaus: I have 3 sets of lathe tools. Used to have 5, but I gave the Sears set away and sold a sorby set to someone for a good price (for them)
11:22 AM JT-Cave: mine are a mixture of brands with a couple of new ones
11:23 AM unterhaus: huh, the sorby set I think I bought for $50 on clearance at lowe's is now $430
11:23 AM JT-Cave: lowes had turning tools?
11:24 AM unterhaus: yeah, and Record planes
11:25 AM unterhaus: they clearanced the record planes too. I was a bit surprised they didn't all disappear immediately
11:26 AM unterhaus: of course, this was 27 years ago.
11:29 AM unterhaus: Prices on ebay are all over the place. I should try it for $275 obo and see what happens
11:31 AM unterhaus: some had 43 and sold them all at $300
11:34 AM roycroft: yeah, the sorby stuff is really pricey now
11:34 AM roycroft: i got a harbor freight set many years ago, when i got my previous lathe
11:34 AM roycroft: which i hardly ever used
11:34 AM roycroft: when i got the new lathe i decided to start upgrading the tooling
11:35 AM roycroft: but decent turning tools are in the $80-$200 each price range now
11:35 AM roycroft: since turning is not a big thing for me, i'm not focused on getting a good set of tools right awy
11:35 AM roycroft: i got the chuck, and i need some more jaws for it, and i got a drill chuck for the lathe
11:35 AM roycroft: and a decent live center
11:36 AM roycroft: i just got the bed extension, so more chuck jaws and more tooling will be next on the list, but it's not a priority for either right now
11:36 AM roycroft: the hf tools work ok, but i have to sharpen them every 28 seconds or so
11:37 AM roycroft: hopefully i'll have replaced them all before they get ground down to little stubs
11:39 AM Alicrow-phone: I have a Grizzly G0462, a set of small PSI tools (like 12" long), some full-size (like 2+ feet long) carbide Simple Woodturning Tools, and a set of medium-sized tools from Harbor Freight.
11:40 AM unterhaus: I bought a lathe from someone that was a bit obsessive and got a lot of tools with it
11:40 AM unterhaus: he had converted from 3 phase to single phase by replacing the motor, thinking about reversing that
11:40 AM roycroft: i had a cheap, hf quality 40" lateh before
11:41 AM roycroft: it was pretty crappy, and i had no room to set it up in the shop, so it was in storage most of the time
11:41 AM roycroft: i finally got rid of it and got a nova comet ii, which is a nice little machine
11:41 AM roycroft: and it's a short bed
11:41 AM Alicrow-phone: My first lathe was a 10", really limiting when making bowls. I got the 16" Grizzly, and then randomly found some free 15" diameter wood on the side of the road. Man, there is a SERIOUS difference between a 10" piece and a 15". Actually broke the banjo when the tool caught.
11:41 AM roycroft: i can haul it out and set it up on my workbench and it works nicely there
11:42 AM roycroft: most of the turning i do is short pieces, so it's a very nice solution for me
11:42 AM roycroft: and i just got the bed extender, which lets me turn pieces 40" long
11:42 AM roycroft: i'll rarely use that, i'm sure, but it's nice to have
11:42 AM unterhaus: I have been thinking about getting rid of my lathe, takes up too much space in the shop
11:43 AM roycroft: i have absolutely no use for it now, but decided i should get it now, because when the day comes that i need it, it may be discontinued
11:43 AM unterhaus: I wish I hadn't noticed that the jessem clear cut is on sale
11:43 AM roycroft: i haven no interest in turning bowls
11:43 AM Alicrow-phone: I love woodworking, especially on the lathe, but I rarely have the time for it unfortunately.
11:43 AM roycroft: maybe some day, but right now i have zero interest in them
11:44 AM roycroft: but i make tool handles, drawer pulls, etc. on the lathe
11:44 AM roycroft: and i want to start making wooden hinges, which i'll be able to do on the lathe
11:44 AM roycroft: that was actually the thing that made me decide it was time for a new lathe
11:45 AM roycroft: rob cosman sells a jig for making wooden hinge components, and it's nice, but it's over $100
11:45 AM roycroft: incra make a wooden hinge jig, which is also expensive, and doesn't do what i need
11:45 AM roycroft: but a lathe with pen jaws on the headstock and a drill chuck on the tailstock will do exactly what i need to do
11:46 AM roycroft: i could have made a drill chuck jig to do it as well
11:46 AM roycroft: i just need to drill some small holes in the centers of dowels
11:46 AM Loetmichel: hehe, just got my ticket for ignoring the overdue TÜV on my other car for 8 months. 88.50eur... pretty cheap considering its germany... what totally surprised me: you can pay traffic tickets via paypal in germany now... Did hell freeze over? a "Behörde" in germany that uses the internet???
11:46 AM roycroft: but the lathe setup is self-aligning, while the drill press requires setup every time
11:48 AM roycroft: https://www.teknatool.com/products/lathes/nova-comet-ii-midi-lathe/
11:48 AM roycroft: that is the lathe i bought last summer
11:48 AM enleth: Loetmichel: *and* it's not SOFORT
11:49 AM enleth: Loetmichel: you are all crazy in there for widely trusting that "payment method"
11:49 AM Loetmichel: enleth: its "instant" in the sense that you get the "paid" reciept from the police server back instantly. everything else doesent bother me.
11:50 AM Loetmichel: it was just suirprising that the police even OFFERED anything internet based at all
11:51 AM enleth: Loetmichel: what I mean was, it's surprising they went with PayPal and not SOFORT
11:51 AM enleth: that thing is horrifying
11:51 AM Loetmichel: oh, they have sofortüberweisung AND giropay as alternatives
11:52 AM enleth: but of course
12:01 PM JT-Shop: damn that wind is sharp today
12:01 PM roycroft: loetmichel: they are learning to take the money however they can get it
12:01 PM roguish[m]: good morning..... going to be near 70 today.....
12:03 PM Loetmichel: roycroft: point was that german officials are notoriously "yesterday"... that they use the internet AT ALL is already a miracle... but offering payment via net? Unthinkable
12:03 PM JT-Shop: I would have to add today, tomorrow and Saturday together to beat that
12:03 PM roycroft: yes, i get that
12:03 PM roycroft: but money is money
12:03 PM roycroft: and eventually, even people who live in the past figure out how to accept money in the present
12:04 PM roguish[m]: JT-Shop: a little chilly there?
12:23 PM roycroft: my linear motion rails are out for delivery, finally
12:24 PM roycroft: i'll get to see how crunchy the bearings are soon
12:36 PM JT-Shop: sun is shining and the wind chill is -12°C or 11°F
12:42 PM JT-Shop: I have this Longworth style chuck but it doesn't seem to hold a bowl good enough to cut unless I'm just not using it correctly... https://www.rockler.com/media/catalog/product/cache/5c5edcf249a74e99ece620285918bb9b/4/9/49046-01-1000_1.jpg
12:47 PM roycroft: i've never used one of those plates
12:48 PM JT-Shop: neither have I successfully
12:48 PM roycroft: i'd probably hold the work in with the tailstock though if i were useing one
12:48 PM roycroft: it seems a bit scary
12:49 PM JT-Shop: I might try it one more time with the tailstock and it is indeed scary
12:53 PM roycroft: *sigh* an anti-vaxer czech folk singer intentionally got herself infected with covid-19 so she could be "done with covid"
12:53 PM roycroft: she is "done with covid", because she died from it
12:59 PM * JT-Shop wonders how many people get infected on purpose?
01:00 PM roycroft: too many, sadly
01:00 PM roycroft: it's become a thing
01:00 PM JT-Shop: as cold as it is I've doubled up on deer food and corn
01:01 PM JT-Shop: there is not one bit left in the morning
01:01 PM roycroft: 95% of hospitalized people with the omicron strain are unvaccinated
01:02 PM roycroft: one would think that would be an indicater of what people should be doing
01:07 PM JT-Shop: unfortunately a lot of folks are a bit nuts and don't rationalize stuff correctly
01:15 PM roycroft: we were discussing this at dinner last night, and consensus was that it's very possible that right wing leaders are intentionally putting out misinformatin for political gain, and that they are being supported by wealthy people, who have profited insanely from the pandemic
01:16 PM roycroft: the wealth of the top 1% of our population has gone up $15,000/second over the past two years
01:16 PM roycroft: while it was increasing before then, the rate of increase really accelerated when the pandemic started
01:18 PM roycroft: the average income of a minimum wage worker in this country is close to $15000/year
01:27 PM W1N9Zr1 is now known as W1N9Zr0
01:40 PM Alicrow-phone: Okay, so I thought all rotary phase converters worked by running a single-phase motor to power a 3 phase generator. Apparently most of them run a 3 phase motor with single phase and the third winding acts as a generator and produces the third phase.
01:42 PM roycroft: yup
01:42 PM roycroft: that is the most common
01:42 PM Alicrow-phone: Which is kinda cool, but I was really confused about how the heck it uses the two single-phase (180 degrees out of phase) lines as lines in a three phase system (120 degrees out of phase).
01:42 PM JT-Shop: you only need one 3 phase motor for a self starting rpc
01:42 PM roycroft: i've seen folks do a phase converter by connecting a single phase motor to a 3 phase motor with a belt and some sheaves
01:42 PM Alicrow-phone: After some research, I found a graph of the waveform, and it blows my mind.
01:43 PM JT-Shop: $1,036,800,000 seems like a pretty hefty raise for one day
01:43 PM roycroft: yes
01:43 PM Alicrow-phone: After some research, I found a graph of the waveform, and it blows my mind.
01:43 PM JT-Shop: I've see lawnmower motors used to start a rpc as well
01:43 PM roycroft: and we were also discussing the point at which wealth is no longer about the money at all
01:43 PM Alicrow-phone: https://images.app.goo.gl/WSi9oftcM6AsXugW9
01:44 PM roycroft: we concluded that it's somehwere in the $50-$100 million dollar range
01:44 PM roycroft: if you have that much money, you really don't need any more
01:44 PM roycroft: it shifts from being about power and money to just being about power around there
01:46 PM Alicrow-phone: So basically the third phase is higher voltage and shifted, such that the line-to-line voltage follows typical 3 phase waveform, but if you look at it referenced to ground it's all weird.
01:52 PM roycroft: as of 2018 it took an income of ~$730k/year to be in the 1% bracket
01:52 PM roycroft: it's probably close to twice that much now
01:52 PM roycroft: certainly over $1 milllion
01:54 PM Alicrow-phone: roycroft: I have some pretty serious doubts about that claim of $15k/second. Accordingly to Wikipedia, the wealthiest person in the world has a net worth of $177 billion. At $1.296 billion per day, that would have been accumulated within 137 days. So even the wealthiest person in the world didn't earn at that rate.
01:57 PM JT-Shop: and 3.295 million people getting $15k a second is a bit out of touch
02:01 PM Tom_L: not if i'm one of them :)
02:01 PM Tom_L: .... which of course i'm not
02:01 PM Tom_L: enjoying the weather?
02:04 PM roycroft: alicrow-phone: that's the aggregate increase, not the increase for each individual
02:04 PM Alicrow-phone: Okay, that makes more sense.
02:05 PM roycroft: and while that is still an obscene number, it is quite plausible
02:05 PM Tom_L: so roycroft how'd you come out on the corner issue?
02:06 PM roycroft: i have not found a solution for that
02:07 PM Alicrow-phone: I'm guessing you're just talking about in the USA or something? Because if you mean the top 1% of the world, that's only $16.41/day.
02:09 PM roycroft: yes, i said in this country
02:09 PM roycroft: anyway, i think we should probably be done with that conversation
02:10 PM roycroft: besides, it's lunch time for me
02:25 PM roycroft: one of the things that frustrates me is that i have several solidworks books
02:26 PM roycroft: they all tout paremetric modeling as so intuitive, because it mimics machining processes
02:26 PM roycroft: and that to be succssful with it one *should* mimic machining processes
02:26 PM roycroft: including orders of operations
02:27 PM roycroft: it's common in manufacturing to assemble parts together and then perform a machining operation on the assembled parts
02:27 PM roycroft: as opposed to machining the parts individually and then assembling them
02:27 PM roycroft: yet sw does not see to allow me to do this "natural" thing
02:28 PM roycroft: i even remember being told this in my sw class - the instructor said early on that for the machinists in the class, it should come easily as they just need to model their parts as though they were machining them
03:03 PM unterhaus: I don't think solidworks is like machining at all, but it's like all the other 3d parametric solid modeling programs I have run
03:03 PM unterhaus: must have been a mistranslation from the French
03:09 PM roycroft: it kind of is
03:10 PM roycroft: you start out with a cube
03:10 PM roycroft: you machine the corners down until you have an arch
03:11 PM roycroft: you do the same thing in solidworks - you draw an arc on the cube and then you cut it away
03:11 PM roycroft: then you rotate the part on the mill and you drill a hole in the top of the arch
03:11 PM roycroft: you do the same thing in sw
03:11 PM roycroft: in a somewhat abstract way it's like machining
03:12 PM roycroft: anyway, i did find a method that supposedly lets me do what i need to do
03:12 PM roycroft: and that's actually even more like a real machining operation
03:12 PM roycroft: i'm supposed to select the parts in the assembly that i want to fillet
03:12 PM roycroft: join them together to make on part
03:13 PM roycroft: then fillet the part
03:13 PM roycroft: if i'm bulding a table top i'll glue the edge pieces together, "joining" them
03:13 PM roycroft: then i can fillet the resulting corner
03:14 PM roycroft: the problem is that i'm not seeing the menu options to do this, as documented by dassault systemes
03:15 PM roycroft: perhaps i need to do this before adding them to the main assembly component
03:15 PM roycroft: lunch break is over, so i won't be able to try again until after work
03:22 PM JT-Shop: aye if you save an assembly as a part then you can do part operations on the whole thing
03:23 PM * JT-Shop goes back to making a pile of shavings back by the lathe
03:24 PM roycroft: i could do that
03:25 PM roycroft: but then i'd have to break this assembly apart, because there are components i don't want in the joined part
03:25 PM roycroft: supposedly there's a mechanism to select parts of an assembly and join them without joining the entire assembly
03:25 PM roycroft: i'd still rather not do any of that, but it may be my only option
03:26 PM roycroft: the problem being that if i change the joined parts the original part files will not update
03:54 PM Tom_L: planning is key
04:05 PM roycroft: having good tools that one is adept at using is also key
04:08 PM * JT-Shop has no clue what roycroft is trying to do...
04:31 PM JT-Shop: whatever it is it sounds painful
04:31 PM Tom_L: very
04:31 PM Tom_L: picture a picture frame with 45 corners joined
04:31 PM Tom_L: he wants a chamfer on the assembly corners
04:32 PM Tom_L: but wants to keep the part geometry of each part
04:33 PM Tom_L: so when he flys by the table and bumps into it, he won't slice his self open
04:37 PM JT-Shop: doesn't make any sense to do that
04:37 PM Tom_L: agree
04:37 PM Tom_L: i don't even think catia will do that
04:38 PM Tom_L: without screwing up the models
04:38 PM Tom_L: i haven't tried it
04:39 PM roycroft: that ability is not a show stopper
04:39 PM roycroft: and i've spent enough time trying to get it sorted for now
04:39 PM roycroft: i've already moved on, for now
04:41 PM roycroft: but as i've said before, sw has assembly features, and when those features modify the underlying parts, when saving/exiting it asks if i want to save the parts as well
04:41 PM Tom_L: JT-Shop, how do you edit the sketch tools dropdown menu?
04:41 PM Tom_L: i wanted to add a feature to it
04:42 PM Tom_L: oh wait... this one has it
04:42 PM Tom_L: i was using an old version last night
04:44 PM JT-Shop: right click on a blank space and and select Customize Menu
04:44 PM JT-Shop: you can change tool bars, menus, mouse gestures and who knows what else
04:44 PM Tom_L: i know it's just been a long time..
04:45 PM JT-Shop: roycroft, you can change things in an assembly and it changes the parts so when you save sw saves any changed parts along with the assembly
04:46 PM JT-Shop: I put parts in an assembly then define the mates then change stuff left and right till the parts are correct and everything lines up
04:47 PM JT-Shop: mouse gestures make quick work of anything
04:47 PM roycroft: yes, that's what i just said
04:47 PM roycroft: and that's why i think i should be able to add a fillet to an assembly and not mess up the parts
04:47 PM roycroft: but again, as i said, i've moved on
04:48 PM roycroft: i can model the entire machine without rounding over those corners and the model will be fine
04:51 PM JT-Shop: are trying to add a fillet between two parts in an assembly?
04:51 PM roycroft: not between them, but "spanning" them
04:51 PM JT-Shop: I understand but have never done that, is that for a weldment?
04:52 PM JT-Shop: https://gnipsel.com/images/chickens/bowls/
04:52 PM JT-Shop: getting a bit better with my bowls
04:53 PM roycroft: no, it's for a table top
05:21 PM roycroft: it won't let me fillet the faces i want
05:21 PM roycroft: i've tried a bunch of ways
05:22 PM roycroft: it only fillets adjacent faces on the same part
05:22 PM roycroft: it won't fillet a face of one part and a face of a different part that are adjacent
05:23 PM roycroft: but really, i have moved on
05:23 PM roycroft: i'm working on my gantry sides now
05:27 PM XXCoder: make your own doubleshot keycap https://youtu.be/VIRkCXVwoXk
05:28 PM XXCoder: very hard
05:32 PM unterhaus: I got the first two cables pulled through my lathe but then my twine broke
05:32 PM unterhaus: I want to pull two more cables.
05:33 PM unterhaus: I have two more pieces of twine pulled through, so strike 1
05:40 PM JT-Shop: fillet the edges not faces
05:40 PM CaptHindsight[m]: if you approach SW or other parametirc modelling packages like you are going to machine the parts to shape then you'll never be able to bury pockets and features into places that are difficult or impossible to machine!
05:41 PM roycroft: unless i'm doing an additive machining process
05:41 PM CaptHindsight[m]: progress will stall and the horses and buggies will win
05:41 PM * roycroft builds his model in sw stacking 0.2mm thick extrusions on top of each other
05:43 PM CaptHindsight[m]: if you plan on only using cutting tools then it makes sense to start with the shape of the stock you are going to use for the parts
05:44 PM CaptHindsight[m]: if only more engineers knew this and had some hands on time making chips they would not end up in the corners that they often do
05:44 PM CaptHindsight[m]: DFM
05:45 PM CaptHindsight[m]: it's a thing since you can design impossible to manufacture parts
05:46 PM CaptHindsight[m]: I would also like to say that some "engineers" are capable of designing things without the use of CAD and still make impossible to fabricate or assemble parts
05:47 PM CaptHindsight[m]: my favorite was a simple enclosure for a resin printer that could only be assembled by someone that could fit inside the printer and stay there after assembly
05:48 PM roycroft: was m c escher one of those "engineers"?
05:48 PM roycroft: i'm sure he inspired many of them
05:49 PM CaptHindsight[m]: ask me why I was almost tossed from the Four Seasons Beijing at 4am for machining in my room
05:49 PM CaptHindsight[m]: the trade show started at 9am downstairs
05:51 PM CaptHindsight[m]: luxury hotel, hahaha, no makerpace, machine shop, tool room etc at those places
05:53 PM CaptHindsight[m]: luxury..... my bottom end
05:53 PM Tom_itx: like the hotel suites at the Ru olympics?
05:55 PM CaptHindsight[m]: i think those still had workers making them when the games began
05:56 PM CaptHindsight[m]: if you even visit Russia, play the game "Who isn't a Russian Spy"
05:58 PM CaptHindsight[m]: in China it's "When am I not Watched?" and "Who isn't Looking?"
06:00 PM unterhaus: Can you make a void in solidworks?
06:00 PM unterhaus: I guess add a sketch to a pocketed surface
06:00 PM Tom_itx: shell
06:00 PM Tom_itx: ?
06:01 PM Tom_itx is now known as Tom_L
06:10 PM unterhaus: If I use the 64 bit rapsbian image from the forum, I wonder how updating will work
06:15 PM perry_j1987: hows it going guys
06:19 PM perry_j1987: looking for options for 120 degree endmills or something
06:19 PM perry_j1987: i need to put a 120 degree bevel on a part
06:21 PM CaptHindsight[m]: https://www.jfberns.com/post/bevel-and-chamfer-whats-the-difference
06:22 PM CaptHindsight[m]: https://www.sansmachining.com/whats-the-difference-between-bevel-and-chamfer/
06:23 PM CaptHindsight[m]: perry_j1987: can you tilt the part 60 deg?
06:23 PM perry_j1987: no
06:24 PM Tom_L: perry_j1987, something like this? http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/15_deg_cutter.jpg

06:26 PM CaptHindsight[m]: Tom_L: have you ever met harvey?
06:26 PM Tom_L: sine table
06:27 PM CaptHindsight[m]: Harvey Tool Company is founded by John Harvey
06:27 PM Tom_L: no
06:27 PM Tom_L: not to my knowledge anyway

06:28 PM Tom_L: :)
06:29 PM CaptHindsight[m]: lizard gear
06:29 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/cutter2.jpg
06:29 PM Tom_L: i forget why i got those but they were free
06:30 PM CaptHindsight[m]: rh and lh styles
06:30 PM CaptHindsight[m]: or CW and CCW
06:34 PM CaptHindsight[m]: perry_j1987: do you have any feedback for the above suggestions?
06:34 PM perry_j1987: looking at links
06:34 PM perry_j1987: re-looking at definition of what included angle means lol
06:35 PM perry_j1987: so far i've found https://www.mcmaster.com/27885a76/
06:35 PM perry_j1987: dont pay attention to the picture they used. the pdf shows how shallow the angle actually is
06:36 PM CaptHindsight[m]: ok, off to make fresh pasta
07:26 PM _unreal_: not much going on tonight
07:27 PM _unreal_: just endless rain outside :(
07:27 PM _unreal_: so I'm kicking my self
07:28 PM _unreal_: looks like I had the perfect parts for the new cnc machine build and I tossed a few away :(. well "scrapped"
07:28 PM _unreal_: sigh
07:49 PM roycroft: i have linear rails
07:49 PM roycroft: i'll open them up later this evening or tomorrow morning to see how crunchy the bearings are
07:51 PM XXCoder: roycroft: yeah lol
07:51 PM XXCoder: I found quite a lot metal chips in SBRs I bought for a machine
07:54 PM roycroft: i'm going to gently see if the bearings slide at all on the rails
07:54 PM roycroft: but regardless of how that goes i'll be dismantling, cleaning, and refurbishing before i install them
07:54 PM XXCoder: best to do that yeah
07:54 PM roycroft: i'm also happy that my new visa card arrived today
07:55 PM roycroft: i have a visa card from bofa that i don't use
07:55 PM roycroft: they did not like that i don't use it, and asked me if i would mind upgrading it to another visa card with better rewardss
07:55 PM _unreal_: ve7it, this weekend I'll do a lot more testing. I need to setup better "HARD" wires to test the servo controllers
07:55 PM roycroft: no credit check, and my account number did not even change
07:56 PM roycroft: the deal they offered is 0% apr until september 2023, which doesn't matter because i pay my cards off every month
07:56 PM roycroft: but also i'll get an extra $200 cash back if spend $1k on the card by 1 march
07:56 PM _unreal_: ve7it, right now the thing I keep getting with the "one" controller that I have wired up and tested. is if I walk away from the controller array for 10-15min I come back to jibberish on the serial COM.
07:56 PM roycroft: i'll be spending about that much on 80/20 extrusions soon, so i'm basically getting at 20% discount on that stuff
07:57 PM roycroft: so they will get me to use the new card
07:57 PM roycroft: give me a bunch of cash
07:57 PM roycroft: and then the new card will go in the safe with the other cards that i don't use
07:57 PM _unreal_: ve7it, so I dont know if that means there is a bad wire connection, or the DSPIC or "something" on the controller board is damaged?
07:58 PM XXCoder: honestly I dont know why people get credit card
07:58 PM XXCoder: I never got one, and dont think I ever will.
07:58 PM XXCoder: I have large hatred for debt
07:58 PM _unreal_: ve7it, it could be anything from the DSpic, the crystal, the 7805, or the opamp. if I had to guess something wiring quality is my first target.
07:59 PM _unreal_: and by wiring I mean wiring between the encoder and the dspic. the serial COM wiring is a quality setup.
08:01 PM _unreal_: ve7it, after that I suspect any one of those items to be "DAMAGED" by high voltage. the last two things would have to be some kind of "short" or low resistance "bridge" from the soldering. The only other thing that comes to mind is the re-compiled CODE for the 6mhz XTAL.
08:02 PM _unreal_: ve7it, I do wonder if it would be wise to change the code to the 14mhz version or what ever is is? I forget off the top of my head.
08:03 PM _unreal_: ve7it, the next thing I need to do is TIE in this little encoder I have to the "input" so i can try driving the motor
08:04 PM _unreal_: ve7it, this weekend first thing I'm going to do is setup better wiring to the motor encoder. then test each motor controller and see how they all react after ensuring a standard PID settings have been entered.
08:04 PM _unreal_: across all four boards
08:05 PM _unreal_: that will really clear up the strong from the weak if there are such issues.
09:42 PM unterhaus: now I would like to solve the mystery of where I left my boroscope
10:01 PM roycroft: that's easy to solve
10:01 PM roycroft: just figure out the last place you'll think of to look for it
10:01 PM roycroft: and there it will be
10:03 PM XXCoder: think of? nahh
10:03 PM XXCoder: its ALWAYS at last place you look for it
10:44 PM roycroft: i try to think before i act
10:44 PM XXCoder: lol
10:56 PM skunkworks: well - that kinda works..
10:56 PM skunkworks: pcw--home: https://www.youtube.com/watch?v=ogUdjX3zerY
11:03 PM skunkworks: Tom_L: the rigol beeped when I turned it on and came up in chinese...
11:03 PM skunkworks: first time that happened.
11:05 PM skunkworks: I also thought the coils were driven with +/-6 volts. After staring at the circuit I finally noticed it is +/-12v
11:05 PM roycroft: i decided to open up my parcel with the linear rails and the ball screw
11:06 PM roycroft: the instant i broke the outer seal on the package, my entire living room reeked of china
11:06 PM roycroft: so i just ran the package out to the shop
11:06 PM roycroft: i'll deal with it tomorrow
11:47 PM CaptHindsight[m]: roycroft: what does China smell like?
11:49 PM CaptHindsight[m]: Did they include a sample of stinky tofu?
