12:05 AM gloops_: 6 days off an no visible progress
12:11 AM gloops_: just the steel pile got bigger, and the garage got boarded
01:35 AM IchGucksLive: morning
01:38 AM IchGucksLive: morning laurent\
01:41 AM CaptHindsight: any snow in Germany yet?
01:44 AM IchGucksLive: lots of but not here ;-)
01:44 AM Crom: $90 for a radiator for the honda, received 2 3/8" carbide end mills -- usa made 4 flute. Going to see if they work better for cutting the insert holders
01:46 AM RyanS: almost snow in Melbourne and it's nearly summer
01:46 AM Crom: ugh... I need to budget my fleabay purchases... spent $900 in the last week on fleabay. THAT would have bought my cncfusion $619 kit. DOH!!
01:46 AM RyanS: ok I exaggerate
01:46 AM gloops_: lol 900
01:46 AM Crom: However I did need the stuff I bought.
01:47 AM gloops_: if i spend 90 i get worried
01:47 AM Crom: It's nice having that $3339.02 check come in.
01:47 AM CaptHindsight: RyanS: I thought you had to go south to Tasmania for snow
01:48 AM Crom: waiting for about 3 to 5K to come in before the 15th, and another $600 on the 16th. $3k is gone from that.
01:49 AM RyanS: that's true but Melbourne residents like to complain about the weather
01:49 AM IchGucksLive: on that numbers i build whole cnc fleet
01:50 AM Crom: IchGucksLive: give me time. First will be a bit expensive, after that, I can make alot of my own parts.
01:50 AM CaptHindsight: Crom: were you battling the red tape?
01:50 AM Crom: CaptHindsight: more like waiting for them to get off their arses.
01:51 AM CaptHindsight: Crom: did you light a fire?
01:51 AM RyanS: IchGucksLive sounds like a budget navy
01:51 AM RyanS: or a courier service
01:51 AM Crom: I have engaged a lawyer, going after the $142,000 they screwed me out of.
01:53 AM Crom: I got $139,000 - $60K was sent to Financial Analist. My Grandma trust check is not the Grandma and VA trust check... from $325 to now it's $600 a month.
01:53 AM IchGucksLive: RyanS: last weeks fleet work http://tv-profi-gmbh.de/masch_baumh_k.jpg
01:54 AM RyanS: do you sell them?
01:55 AM CaptHindsight: Crom: good for you
01:56 AM CaptHindsight: IchGucksLive: what do you hold in those tiny clamps on the Z-axis?
01:57 AM IchGucksLive: RyanS: NO
01:57 AM IchGucksLive: CaptHindsight: proxxon
01:57 AM IchGucksLive: RPM controlled by pwm
01:59 AM Cromaglious: the $79K left, $10K to business account, $10K to wifes account, $12K to the kids and grandkids, ... New underwear, $8700 fixing the Cadillac (97 Deville -- Grandma's last car), Fix trailer, new to us Fridge and parts, another $7K on fixing step kids cars, $9K on car for kidlette
02:00 AM CaptHindsight: $8700 for underwear?!
02:00 AM Cromaglious: new underwear was about $150 for me and the wife all told.
02:01 AM Cromaglious: sheeshz $60 for 2 bras for her.
02:01 AM CaptHindsight: their underthings cost more
02:02 AM Cromaglious: gone is the swiss cheese wear.
02:02 AM Cromaglious: NEW SOCKS! they feel so good!
02:02 AM Cromaglious: No longer looking so homeless..
02:02 AM Cromaglious: ugh
02:04 AM CaptHindsight: cars can be money pits
02:04 AM CaptHindsight: especially if you pay someone else for labor

02:04 AM Cromaglious: WOW, that's HUGE!!
02:05 AM Cromaglious: Anything labeled Ambermeade is my wife and I.
02:05 AM CaptHindsight: too big to cut n paste
02:08 AM Cromaglious: https://www.facebook.com/events/1972200913048566
02:10 AM Cromaglious: Had alot of fun, the drive from there and back to my brother in laws house was TOO fun. Filmore, CA to Agura, CA hairpins, slaloms, chicains, too fun! I couldn't go as fast as I wanted... You know wife in car...
02:11 AM CaptHindsight: Agoura Hills = Agoura?
02:12 AM Cromaglious: Sheeshz you'd thought we were going off an cliff... The crap on the dash wasn't even sliding around.
02:12 AM CaptHindsight: hah
02:12 AM Cromaglious: Capt yep, Lake Forrest, Thousand Oaks
02:12 AM CaptHindsight: i know the area
02:12 AM CaptHindsight: been a long time
02:13 AM Cromaglious: Agura Hills, where they filmed M.A.S.H., dukes of hazard, dr quinn medicne woman, among others.
02:15 AM CaptHindsight: had friends there with a ranch, horse folks
02:16 AM Cromaglious: Sunday morning, bit damp, but there was enough traffic through that the road was dry. so when we came through, everyone was in church, to cyclists, sweet, sweet drive.
02:16 AM Cromaglious: s/to cyclists/no cyclists/
02:19 AM RyanS: does one use proximity switches for accuracy or to prevent denounce? my initial thought is that good quality micro switches are fine for limit/homing
02:21 AM Cromaglious: RyanS: I use one because it was easier to use. Nowhere to mount a micro, nowhere to stick a magnet. Prox sensor, drill a hole, DONE!
02:22 AM Cromaglious: I'd rather use a micro switch since I think they are more repeatable.
02:22 AM RyanS: a magnet for?
02:22 AM Cromaglious: hall effect sensor
02:23 AM Cromaglious: on a machine that never cuts steel, they're fine.
02:23 AM RyanS: im thinking prox is subject to EMI, especially on plasma?
02:23 AM CaptHindsight: there are different types
02:24 AM CaptHindsight: https://www.ia.omron.com/support/guide/41/introduction.html
02:24 AM Cromaglious: haven't gotten to plasma yet.
02:24 AM CaptHindsight: good overview ^^
02:26 AM Cromaglious: ok, almost midnight, wife is asleep... Nite all...
02:34 AM Deejay: moin
02:57 AM IchGucksLive: later !
05:07 AM jthornton: morning
05:07 AM RyanS: o/
05:16 AM RyanS: jthornton Is there an off the shelf ohmic sensor you would recommend?
05:16 AM jthornton: never used one before
05:18 AM RyanS: you just use a floating head switch?
05:18 AM jthornton: yea
05:18 AM jthornton: I have it connected to the motion probe input and do a probe move
05:25 AM RyanS: can that be automatically inserted into the gcode program in sheetcam (or equivalent)?
05:26 AM jthornton: yes my sheetcam post processor calls my touchoff subroutine to set Z0 and fire the torch the proceeds with the cut
05:30 AM XXCoder: heys
05:33 AM RyanS: aah I can see a "Linux cnc THC" post processor, is that one?
05:34 AM RyanS: . the one *
05:35 AM jthornton: is it written by me?
05:38 AM RyanS: actually, no it's the candcnc one
05:40 AM jthornton: hmm
05:44 AM jthornton: http://paste.ubuntu.com/25910159/
05:46 AM jthornton: hmm my plasma pc is not on the lan for some reason
05:47 AM RyanS: thanks. is that for the gmocappy plasma setup?
05:48 AM jthornton: I use Axis
05:49 AM jthornton: post.Text ("M68 E0 Q", Volts, "\n")
05:49 AM jthornton: I use M68 to communicate the volts setting to the thc component
05:56 AM RyanS: so you have a custom axis interface with thc functions?
05:57 AM jthornton: no, just a normal Axis with some pyvcp displays to show voltage and status
06:07 AM alfepu: hola alguien sabe como instalar una version de inkscape que no sea la ultima
06:08 AM alfepu: necesito inkscape 0.91
06:08 AM archivist: that is all greek to me
06:09 AM jthornton: looks spanish to me
06:09 AM RyanS: Spanish
06:10 AM alfepu: nadie habla spanisch
06:13 AM Deejay: non comprende
06:15 AM MarcelineVQ: Deejay: they'd like to know how to install inkscape 0.91 rather than getting the latest one, which is hard to say since we don't know how they're getting it
06:15 AM alfepu: wie es installieren inskape 0.91 in ubuntu 17.10
06:16 AM MarcelineVQ: there's links here for inkscape 0.9.1 https://inkscape.org/en/release/0.91/?latest=1 including a couple options for ubuntu https://inkscape.org/en/release/0.91/gnulinux/ubuntu/
06:17 AM alfepu: no eso ya lo intente segui los pasos pero al final solo me deja instalar la version nueva
06:19 AM MarcelineVQ: that gave you 0.92 anyway? I don't know then sorry
06:20 AM alfepu: thanks yoz
06:20 AM alfepu: you
07:46 AM MarcelineVQ: "make an electromagnetic chuck out of an old microwave!" holding requring power flow? sounds like a good way to get yourself killed
07:46 AM MarcelineVQ: related link https://www.youtube.com/watch?v=AEvjRzpr28Y
07:50 AM sync: the big chucks on surface grinders are also always powered
07:52 AM MarcelineVQ: the ones I've seen are lever action to engage them, seemed to me like that would be moving the mags up or down to engage holding, are you saying they're still electromagnets though?
07:53 AM archivist: move magnets, not electromagnets
07:54 AM SpeedEvil: Some of the really big ones use electromagnets to move the magnets
07:56 AM sync: no, there are electromagnetic ones
08:06 AM gloops: it seems the 'Silverline' range of cheapo power tools are the same as the older 'Pro-power' eastern european brand, now liquidated
08:06 AM gloops: just bought a silverline bench grinder - exactly the same as the pro power one that broke
08:07 AM gloops: or- looks exactly the same externally anyway
08:08 AM MarcelineVQ: https://www.youtube.com/watch?v=tUQg2WiHpUY at 4:30 does anyone know what these white boxes are? my first thought it resistor but there's already smaller ones just above it which makes me wonder why you'd need larger wattage ones, it's just a hall effect sensor.
08:09 AM sync: they are just foil capacitors
08:09 AM MarcelineVQ: I see, yes there's images that look like that, how could you tell right away? a little tall for resistors?
08:11 AM sync: look at the number
08:13 AM MarcelineVQ: mymy you can read that? it's a blur to me, must come with an experienced eye
08:13 AM MarcelineVQ: thank you though
08:14 AM sync: it says 4n7 quite clearly on there
08:20 AM gloops: unbelievable, a nut i ordered from china last week just arrived, ballscrews payed for a month ago no sign
08:21 AM MarcelineVQ: it's funny how they all come from the same factories but they all ship differently
08:21 AM gloops: this was like a 10 pence item, maybe quicker for small parcels
09:13 AM gloops: well, my diy surface grinder (or overhead grinder heh) does/will work
09:14 AM archivist: might
09:15 AM gloops: small 150w motor cuts fine with light steady passes on steel, archivist was right though, column not stiff enough
09:15 AM archivist: possibly
09:15 AM archivist: hopefully
09:15 AM gloops: just been cutting with it
09:16 AM SpeedEvil: What are you doing it again?
09:16 AM gloops: its o...k with steady feed, once it bumps something it starts a light judder off
09:16 AM archivist: I want a real surface/cylindrical/tool grinder
09:16 AM gloops: Speedevil kill the motor on the first grinder i used
09:16 AM gloops: if i steady the column with just finger pressure its fine
09:17 AM gloops: luckily the column is between two steel roof supports so easy cure for that
09:18 AM gloops: archivist - no room for a fully equipped workshop
09:19 AM archivist: space, what is that?
09:19 AM gloops: a good surface grinder is a lovely machine to use
09:20 AM MarcelineVQ: once with nice particulate collection
09:20 AM archivist: my home brew tool grinder sharpened a cutter ok
09:21 AM gloops: its blowing it to the side Marcel, not so bad
09:23 AM MarcelineVQ: the side, the wall, the floor, the air :> maybe it's not so bad with surface grinders but a grinding room in a welding shop is a dirty place
09:24 AM archivist: with added shot blasting monkeys
09:24 AM gloops: well not exactly a fettling shop, will only use it now n again
09:25 AM gloops: can true up z axis and others if i dial them in
09:25 AM gloops: near enough
09:25 AM MarcelineVQ: something to keep in mind anyway, some suction on your grinders keeps a place nicer longer
09:25 AM gloops: it might be a bit late for that lol
09:38 AM hazzy: rene-dev: Did you get a chance to talk with Norbert about porting Gremlin3?
09:52 AM sync: MarcelineVQ: just grind wet
10:03 AM gloops: a small vac set up would be good actually with my thing, it grinds away from the headstock which i didnt want to get gritted up, tailstock off when i use it, but better without grinding dust over the lathe
10:19 AM hazzy: What kind of vacs so you all use for grinding? The typical shop vac only lasts me about a month before the bearings are shot from the grit, and that is with a good filter.
10:19 AM hazzy: In desperation I tried a dyson but that lasted only a few hours :(
10:20 AM hazzy: Now I try not to grind or bead blast ...
10:21 AM ziper: hazzy, what about an aspirator?
10:21 AM hazzy: That is an idea!
10:22 AM hazzy: I don't have much shop air, but I could possibly get enough draw with the exhaust form a shop vac ...
10:23 AM hazzy: hmmm
10:23 AM sync: hazzy: I have not had an issue with a cheap kärcher
10:24 AM SpeedEvil: hazzy: you can add a trap.
10:24 AM SpeedEvil: Annoyingly, I can't find the sort of product I was thinking of
10:25 AM SpeedEvil: https://www.ebay.co.uk/itm/Ash-Vacuum-Fireplace-Wood-Burner-Vacuum-Cleaner-Collector-Hoover-Dirt-Vac-15L/391073240174
10:25 AM SpeedEvil: Basically this, but with just a port on the top that you connect to another vacuums suction hose
10:26 AM SpeedEvil: https://www.amazon.co.uk/gp/product/B01L1GBAMI/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 + a small drum works OK too
10:26 AM hazzy: SpeedEvil: I have tried that with a 5 gal drum and baffles, but it only helps a little
10:26 AM SpeedEvil: what are you grinding?
10:26 AM hazzy: maybe I should have the air pass thru water
10:27 AM hazzy: Just general grinding of mild steel and HHS tools
10:27 AM hazzy: HSS*
10:27 AM hazzy: and bead blasting
10:28 AM SpeedEvil: ah.
10:28 AM SpeedEvil: Bead blasting can make lots of rather fine stuff
10:30 AM hazzy: yes, very fine powder that does not like to drop out of the air
10:30 AM hazzy: I think the killer is mainly that the small vacs arnt intended for continuous duty, I guess I should invest in a real collection system
10:31 AM SpeedEvil: https://www.amazon.co.uk/gp/product/B005C9GXUK style is pretty easy to cobble together
10:31 AM gloops: maybe just an extractor for a lot of grinding, blow it outside into an open collector
10:31 AM SpeedEvil: even if you don't buy it.
10:31 AM SpeedEvil: DIY fan, random motor.
10:31 AM SpeedEvil: ^impeller
10:32 AM SpeedEvil: Boxing up the bag/filter and putting the motor on the other side is also a good idea
10:33 AM hazzy: I have a ~14" mg impeller from a 1964 Corvair and some spare motors, ill rig something up and see how it works
10:35 AM IchGucksLive: hi from cold basement ;-)
10:35 AM Todd_Z: The problem with most cheap shop vacs is that the use the vacuum air stream for cooling the motor, so any crap that goes through your filter goes through the motor.
10:36 AM IchGucksLive: i made a How to on Toolchange on a Chees router
10:36 AM IchGucksLive: https://youtu.be/1M2yqr3lKfo
10:36 AM IchGucksLive: can someone check the crap english
10:36 AM Deejay: no, too much headache
10:37 AM IchGucksLive: MarcelineVQ: as your request
10:37 AM IchGucksLive: Deejay: i will do a german pälzich one
10:38 AM sync: you did not burn down the mill :/
10:40 AM IchGucksLive: later
11:21 AM roycroft: so yay - my tool cart is gone and my wallet is full of cash
11:21 AM roycroft: looks like a new router lift is in my near future
11:22 AM roycroft: finally a real mechanic showed up to check out the cart and not a weekend warrior or old fart tire kicker
11:23 AM SpeedEvil: yay
11:24 AM hazzy: roycroft: What router lift do you have in mind?
11:25 AM roycroft: the incra mast-r-lift ii
11:25 AM roycroft: which is the jessem mast-r-lift ii but made for incra with magnetic ring inserts
11:25 AM roycroft: http://incra.com/router_system_accessories-mast-r-lift-ii.html
11:25 AM hazzy: Good choice!
11:25 AM hazzy: I have the NCRA Mast-R-Lift II and love it!
11:26 AM roycroft: i'm going to be getting an 80mm spindle for the thing
11:26 AM roycroft: and the mast-r-lift ii seems to be the easiest one to adapt to that spindle
11:27 AM roycroft: i have a call into jessem to find out if there's a setting that will fit out of the box
11:27 AM roycroft: if not, i can make some spindle holder blocks for it
11:27 AM roycroft: i measured a p-c 690 body last night and it's 3.47" in diameter
11:27 AM hazzy: I would be easy to modify the included "jaws" to fit
11:28 AM hazzy: I have the 690 too :)
11:28 AM roycroft: so 0.320" bigger than the new spindle
11:28 AM roycroft: i have two 690s now
11:28 AM roycroft: but i don't use them in my router lift - i have a 7518 for the current lift
11:29 AM roycroft: having two 690s is handy for cutting dovetails with the leigh d4
11:29 AM roycroft: one for the dovetail bit, one for the spiral straight bit
11:29 AM roycroft: one of my 690s i've had since the early '80s, btw
11:29 AM roycroft: and it still works as well as it did 35 years ago
11:29 AM hazzy: My only complaint about the Mast-r-Lift is with the way the height adjust locks by wedging the screw. It moves the router up by about .005" when locked.
11:30 AM roycroft: it does?
11:30 AM roycroft: bummer
11:30 AM roycroft: is that repeatable?
11:30 AM hazzy: But is is consistent so you can accommodate
11:30 AM roycroft: ok
11:30 AM roycroft: as long as it's repeatable
11:30 AM roycroft: have you done the backlash elimination adjustment on it?
11:31 AM hazzy: yes
11:32 AM roycroft: i was originally going to get a stepper motor for height adjustment, but decided that's overkill for what i'm doing
11:32 AM roycroft: i am going to put a dro on it though
11:32 AM roycroft: so as long as the locking offset is repeatable, i can dial the bit up to 0.005" less than my final height and then lock and be spot on
11:33 AM hazzy: I have modified the lift to automatically lock the spindle when the collect is raised above the table, makes bit changes a joy
11:33 AM roycroft: i just don't want to have to "bump" it like a biesemeyer fence on a table saw
11:33 AM hazzy: Yes, it is very repeatable, you will be happy I am sure
11:34 AM roycroft: i am back to working on my router table design, so this is good timing
11:34 AM roycroft: i can design for the new lift :)
11:34 AM roycroft: and sell my old lift
11:35 AM roycroft: i also just found a $25 off coupon for incra.com
11:35 AM roycroft: plus, the mast-r-lift ii is on sale right now
11:37 AM hazzy: the stars are aligned
11:38 AM roycroft: the easiest thing for me to do would probably be to make some pads to shim out the spindle grippers
11:38 AM roycroft: assuming there's not a setting that can accomodate the spindle out of the box
11:39 AM hazzy: The spindle grippers are attached with solder screws, there are a bunch of holes you can choose for different spindles
11:39 AM hazzy: You could just drill new holes
11:40 AM hazzy: If you have a mill or a good drill press ...
11:40 AM roycroft: yes, if there's room for the new holes where i would need them
11:40 AM * roycroft has both
11:40 AM roycroft: i'll find out what my options are when jessem call me back
11:40 AM roycroft: their customer service person is at lunch
11:41 AM roycroft: i think it's a great lift, with one shortcoming
11:41 AM roycroft: there's no quick raise/lower feature, which the woodpecker's one has
11:41 AM roycroft: but i don't anticipate changing bits out constantly, so that's not a major issue
11:42 AM hazzy: Yes, but it is some soothe to operate you are a little sad when the cranking is over :D
11:43 AM hazzy: Here are some pictures of my very basic table I built about 6 years ago:
11:43 AM hazzy: https://i.imgur.com/QZohW9P.jpg
11:43 AM hazzy: https://i.imgur.com/4h36NfJ.jpg
11:44 AM hazzy: https://i.imgur.com/CHsu7jr.jpg
11:44 AM roycroft: nice and clean and simple
11:44 AM roycroft: i'll be building a big cabinet on wheels for mine
11:45 AM roycroft: my plan is to store all my routers/bits/accessories in the router station cabinet
11:45 AM roycroft: i have an incra ls positioner as well
11:45 AM roycroft: what i'm thinking of doing is mounting the incra jig on a little extension to the router table top that is hinged
11:45 AM hazzy: Nice, Id love to have one of those positioners
11:46 AM roycroft: so when i'm not using it i can swing it down and out of the way
11:46 AM hazzy: That is a great idea!
11:46 AM roycroft: i just replaced my old ultra jig with the new version with the wonder fence
11:47 AM roycroft: i got the ultra in the mid-90s, used it for 20 years, and still was able to sell it for $200
11:47 AM roycroft: so the upgrade wasn't that expensive
11:47 AM jthornton: how to you tell what outgoing traffic you might have from cameras?
11:48 AM roycroft: hazzy: i don't like cutting dovetails with the incra jig
11:49 AM roycroft: i use my leigh d4 pro for that - i mostly cut through dovetails and it's way too fiddly with the incra jig
11:49 AM roycroft: but it's great for other joinery tasks
11:51 AM hazzy: yeah, I have a rockler POS dovetail jig, so its normally faster for me to just cut dovetails by hand
11:52 AM hazzy: I do use a rounder free hand to clear the bulk of the waste
11:52 AM roycroft: i got the d4 off cl a while back - i had been looking for years
11:53 AM roycroft: and i upgraded it to the pro, and got the dust collection attachment for it
11:53 AM roycroft: i'm very happy with the jig
11:54 AM hazzy: Nice! I would probably use a jig if it was quick enough to set up and had adjustable pin/tail sizes/spacing
11:54 AM roycroft: for half blind dovetails, though, i think the incra jig will probably be better
11:54 AM roycroft: i rarely make half blind dovetails
11:56 AM hazzy: I mainly use dovetails for drawers so want half blind: https://kurtjacobson.weebly.com/uploads/5/8/4/2/58426975/2258302_orig.jpg
12:04 PM JT-Shop: nice
12:04 PM JT-Shop: but your shop is too clean...
12:06 PM hazzy: JT-Shop: I know, it drives my brother crazy to be in my shop, and it drives me crazy to be in his shop!
12:06 PM hazzy: Different ways of working :D
12:07 PM hazzy: He gets more done in a day than i do ...
12:11 PM roycroft: those are some pretty beefy dovetails
12:13 PM archivist: impossibly tidy shop
12:14 PM hazzy: roycroft: The parts with the tails are only 5/8" thick drawer sides
12:14 PM archivist: I leave blocks under mills etc for easy moving
12:15 PM IchGucksLive: hi
12:15 PM IchGucksLive: Deejay: noch am rechner
12:15 PM hazzy: archivist: Same here :) But I am very short so the extra height is sometimes a pain
12:15 PM Deejay: nope
12:16 PM IchGucksLive: Deutsch German https://youtu.be/t0LBWOekKIk
12:16 PM hazzy: IchGucksLive: Good video!
12:16 PM hazzy: The "English" one I mean :)
12:17 PM hazzy: Hmm, does anybody have a config were different axes have different units from those given in TRAJ? Working on the DRO in hazzy and want to cover odd use cases.
12:18 PM cradek: xyzuvw are all linear units, either inch or mm (all six the same units); abc are in degrees
12:18 PM hazzy: But they the units can be specified in the AXIS section as well to override the TRAJ units, right?
12:19 PM cradek: do you mean so you can have X be inches and Z be mm? that absolutely will not work
12:19 PM cradek: if such a thing is allowed in the ini file it's an accident/bug
12:19 PM SpeedEvil: feature!
12:20 PM hazzy: Yes. So what is the point of the [AXIS_#] UNITS setting in the INI?
12:20 PM IchGucksLive: feature
12:20 PM cradek: I have no answer for that
12:20 PM hazzy: OK :)
12:22 PM hazzy: http://linuxcnc.org/docs/2.7/html/config/ini-config.html#_axis__lt_num_gt_section
12:22 PM hazzy: "UNITS = INCH - If specified, this setting overrides the related [TRAJ] UNITS setting."
12:23 PM IchGucksLive: makes no sense as type is the main axis factor
12:23 PM cradek: welp
12:24 PM hazzy: Oh, it might override the [TRAJ] XXX_UNITS globally
12:34 PM IchGucksLive: Deejay: nur für dich !
12:43 PM andypugh: hazzy: I see your shop has sash windows. Have you ever tried making one? I have, and it is amazing how many bits of wood there are in one. We made We made 7 of them out of a single large pitch-pine beam. It took an age.
12:46 PM nullifier: Are there any x86 prebuilt images for linuxcnc that are under 512mb?
12:46 PM nullifier: I have this PC104 SBC, but only 512mb industrial flash onboard
12:46 PM hazzy: andypugh: Yes I have made sash windows, probably the most enjoyably thing I have made! Our house was hit by a large oak as it fell and destroyed the original windows so I made the three replacements.
12:47 PM andypugh: Did you make them out of the fallen tree?
12:47 PM hazzy: andypugh: If you scroll down a bit here you can see pictures of the windows: https://kurtjacobson.weebly.com/project-gallery.html
12:47 PM hazzy: No, but that would have been fun!
12:48 PM hazzy: I made them out of old growth fir to match the other windows
12:48 PM andypugh: Ah, I was wrong, you don’t have sash windows?
12:48 PM hazzy: They are not sash,
12:49 PM andypugh: The one behind your dovetail pile looks to be.
12:49 PM hazzy: The ones I made are not sash, but the house does have sash.
12:49 PM andypugh: It’s all the bits in the balance weight cases that really add up :-)
12:49 PM hazzy: yes I bet!
12:50 PM roycroft: modern sash windows are usually made with springs instead of counterweights
12:50 PM roycroft: they're easier to make and there aren't big, hollow, uninsulated cavities
12:51 PM andypugh: You can see 6 of the 7 in the first pic here, clearly taken while we were making the 7th. http://www.bodgesoc.org/Slaithwaite2/Slaithwaite2.html
12:51 PM hazzy: Yes, but they do not work as smoothly
12:51 PM roycroft: but yes, the old style are very fiddly
12:52 PM hazzy: Those look nice!
12:52 PM andypugh: The rest of the house doesn’t have those new-fangled sashes, it has unglazed timber mullions. (But we cheated, by adding glazing behind)
12:53 PM andypugh: (In all those pictures there are only three bits of wood visible that we didn’t put there)
12:54 PM hazzy: That is a beautiful house.
12:54 PM hazzy: had it all moldered away over the years?
12:55 PM hazzy: That is the house you re slated with the original slates, right?
12:55 PM andypugh: Aye, we are rather proud of it. It looked like this when my parent bought it. http://www.bodgesoc.org/before1.jpg
12:56 PM hazzy: WOW, big improvement! though the ventilation is not as good now :)
12:57 PM andypugh: The heating is cheaper, though.
12:57 PM hazzy: How long have you all been working on it for?
12:58 PM MarcelineVQ: "<sync> MarcelineVQ: just grind wet" even better
12:58 PM andypugh: It took us 15 years, just me and my dad working weekends.
12:59 PM MarcelineVQ: IchGucksLive: I don't think it was me that asked about that but it's a good thing to make a video about
12:59 PM IchGucksLive: ;-)
01:00 PM IchGucksLive: MarcelineVQ: did you look at the video
01:00 PM MarcelineVQ: watching it at the moment, 3 mins in
01:00 PM MarcelineVQ: I'd like to make a touch probe for this sort of thing once I have a router going that can cut out the pieces for one
01:01 PM andypugh: Igniting your mill is probably not a good idea :-)
01:01 PM IchGucksLive: hi Computer_barf how is it in CA
01:01 PM MarcelineVQ: this sort of probe https://www.youtube.com/watch?v=4a44KysPykg
01:01 PM IchGucksLive: Computer_barf: did you modify your g0704
01:02 PM hazzy: IchGucksLive: I think monkeyisl was the fellow that asked about the tool setter
01:02 PM Computer_barf: Ive never lived in CA
01:02 PM Computer_barf: but I did modify my g0704
01:03 PM IchGucksLive: but your ip does
01:03 PM Computer_barf: damnit my ip is communist
01:03 PM IchGucksLive: as we al are
01:03 PM Computer_barf: im going to be forced to throw my computer out of a helicopter.
01:04 PM IchGucksLive: MarcelineVQ: no this one https://www.youtube.com/watch?v=1M2yqr3lKfo
01:04 PM IchGucksLive: Computer_barf: go as high as you can they might be stable to survive
01:05 PM MarcelineVQ: Yes that's the kind you need to confirm tool height, I'd like a touch one for edge-finding as well though
01:07 PM MarcelineVQ: You could use the same principle for edge finding though especially in a conductive work piece.
01:07 PM Computer_barf: reinstalling my owncloud , you guys would shame me for how i use it.
01:07 PM MarcelineVQ: IchGucksLive: Your spoken english is good, your written english sometimes has spelling errors but not in a way that is hard to understand
01:07 PM IchGucksLive: MarcelineVQ: edge is easy on Metal
01:08 PM andypugh: Talking about edge-finding, here is a way that I came up with recently: http://www.model-engineer.co.uk/forums/postings.asp?th=131421
01:08 PM IchGucksLive: i got 4 buttons on the side to touch of
01:09 PM IchGucksLive: x+ x- y+ y- and a number field to get the tooldiameter calculated in
01:09 PM IchGucksLive: alo a button for hole
01:11 PM MarcelineVQ: andypugh: I'd like to make, some day, a lathe chuck that self-centers a work-piece based on some criteria or pediodic measure like indicating a side, hit pause, indicate another side, center based on that, etc. Mostly from watching abom have to center up with 4 jaw so meticulously, he's really very good at it but it still eats a fair chunk of work-time
01:12 PM andypugh: I don’t think that a 4-jaw takes that long once you compare it to machining time.
01:12 PM IchGucksLive: they are so cheep to buy
01:12 PM MarcelineVQ: No but it's still could be time saved, who knows, would be a fun project at least
01:14 PM gloops: i think that already exists Marcel, commerically anyway, bloke on our street talks about the lathe he uses, it has chucks either end - and passes the job from one chuck to another
01:14 PM MarcelineVQ: if nothing else it could inform the design of a self-centering chuck for a cnc machine
01:15 PM sync: gloops: you have soft jaws for that or a wedge bar chuck
01:15 PM MarcelineVQ: I've seen footage of friction welding machines that pass work between chucks, friction welding is super cool
01:15 PM sync: they center pretty well
01:17 PM gloops: no idea what the machine is called, the stuff he makes isnt big or really impressive
01:19 PM IchGucksLive: gn8
01:20 PM gloops: 4 jaw is not so bad for centering, you go by the lie of the opposing jaws, there are independent 3 jaw chucks which i imagine are a pain to centre
01:21 PM hazzy: An independent 6 jaw would be worse ...
01:23 PM JT-Shop: I only use a 4 jaw chuck
01:23 PM gloops: 6 jaw yes that would be a nightmare i guess
01:24 PM JT-Shop: depends on the part shape...
01:24 PM gloops: hex bar?
01:25 PM JT-Shop: odd shape part for example
01:25 PM JT-Shop: a casting of a steam engine part...
01:26 PM sync: 6 jaws are nice if you need low clamping pressure but high holding power
01:31 PM JT-Shop: that too
01:31 PM * Tom_L checks in for lunch an hour late
01:32 PM gloops: im not sure how a six jaw would be set out, i mean if you have opposin jaws its easy enough to get your head round how to send a piece one way or another
01:32 PM gloops: if the jaws arent directly opposite, its a different kettle of fish
01:32 PM * JT-Shop just finished a slider minus everything but the meat lol
01:34 PM gregcnc: Awkward workholding in a lathe chuck will always be awkward and there are countless ways to hold such
01:35 PM JT-Shop: yea after watching the old guy build a ship engine with just a lathe and back plate and a bunch of scrap bits it's just amazing what you can do
01:46 PM DocHopper: gloops: Leveling a 3d printer bed with 3 points of attachment isn't that bad, so a 3 jaw independent might be fine.
01:52 PM gloops: the awkwardness comes from have 2 offset opposing jaws, if you want to take A in a bit, you have to wind B and C back
01:53 PM gloops: with a NSEW 4 jaw, if you want to take N in, you take S out
01:54 PM JT-Shop: a 3 jaw independent would be a pia to try and center gotta move all three jaws in some direction
01:54 PM JT-Shop: 4 jaw is simple you only adjust in two planes
01:54 PM gloops: right
01:54 PM gloops: you could be faffing about for ages with 3
01:55 PM JT-Shop: yea
01:55 PM gloops: probably be better with 3 clocks on it
01:55 PM JT-Shop: 3 jaw is fine if your going to turn the whole part then part off
01:58 PM SpeedEvil: I suspect using it as a synthetic 6 jaw would be easier.
01:58 PM SpeedEvil: One turn on jaw 1, -0.77 turns or whatever on jaw 2 and 3
01:59 PM SpeedEvil: Always move the opposing jaws as a unit
01:59 PM SpeedEvil: Also, ignore teh term 'synthetic six jaw' I have no idea what I was thinking
02:05 PM gloops: i suppose if you were using one regularly it would become second nature
02:05 PM SpeedEvil: yeah
02:05 PM * Tom_L wonders what a 5 jaw would be like
02:05 PM Tom_L: it got skipped
02:07 PM gloops: centering an independent 5 would be just showing off lol
02:08 PM SpeedEvil: On triangular stock
02:12 PM gloops: https://www.ebay.co.uk/itm/EMCO-UNIMAT-3-LATHE-MILLING-ACCESSORIES/322857491184?
02:12 PM gloops: they really like their mini lathes
02:13 PM roycroft: well, i'm disappointed
02:13 PM roycroft: the customer service person at jessem informed me that it is impossible to mount an 80mm diameter spindle in their lifts
02:13 PM roycroft: and that they've had several prospective customers call with that request in the past
02:14 PM gloops: impossible is a strong word
02:14 PM roycroft: i asked her to clarify if she really meant "we don't support it", and she said "no, i meant it is impossible to do that"
02:14 PM roycroft: and they will not provide cad or pdf drawings of their mounting blocks
02:14 PM roycroft: oh well
02:15 PM roycroft: i can buy one, measure the blocks, and make my own
02:15 PM Tom_L: they should hire a different engineer
02:15 PM roycroft: this is not an engineer
02:15 PM roycroft: it's "customer service"
02:15 PM roycroft: if i talked to an engineer the word "impossible" would never have been used
02:15 PM JT-Shop: customer disservice
02:15 PM roycroft: she was polite but firm
02:16 PM roycroft: but jessem are a canadian company, so the politeness bit was a certainty
02:16 PM Tom_L: she must be old or ignorant
02:16 PM roycroft: i can understand their position
02:16 PM roycroft: if they said that people can mount random devices in their lifts then they would be getting idiots doing so all the time and then suing them when they cut their finger off or put their eye out
02:17 PM roycroft: just saying "no" is a lot safer than trying to assess the caller's skill level
02:17 PM roycroft: i still did not like the answer :)
02:18 PM JT-Shop: what is this lift you speak of?
02:18 PM roycroft: a router lift
02:18 PM roycroft: http://incra.com/router_system_accessories-mast-r-lift-ii.html
02:18 PM Tom_L: oh that fancy table somebody posted yesterday?
02:19 PM roycroft: there are four adjustable gripper pads on it to accomodate routers of varying diameters
02:19 PM roycroft: the spindle that i want to use is not listed among those supported
02:19 PM JT-Shop: one of those that have a crank to raise and lower cool
02:19 PM roycroft: yes
02:19 PM gregcnc: all you need is a sleeve
02:20 PM roycroft: or some spacer pads to attach to their pads
02:20 PM gloops: you cant get an 80mm spindle in there??
02:20 PM roycroft: but the pads have four holes in them, and the pad mounts have five holes in them
02:20 PM roycroft: lining up different hole combinations is how they adjust for different diametgers
02:21 PM roycroft: there may be an undocumented combination that will work with an 80mm spindle
02:21 PM gregcnc: how does that grip thew router?
02:21 PM roycroft: if not, i can always put spacer pads on the ends of their gripper pads
02:21 PM roycroft: you adjust the pads according to their specifications, and the router slides in loosely
02:21 PM gloops: the sleeve would need to clamp the spindle
02:21 PM roycroft: there is an adjustment nut that squeezes the pad aseembly together
02:21 PM roycroft: assembly
02:23 PM roycroft: if the manufacturer would be forthcoming about the tolerances and measurements of the mounting mechanism it would be easier for me to design a modification
02:23 PM gregcnc: A few inches of 6061 tube in the lathe, done
02:23 PM roycroft: but instead, it is "impossible" to mount a spindle such as i wish
02:23 PM gregcnc: I don't bother, i design what I wantand make it
02:23 PM gloops: im surprised they arent onto this, spindles are popular
02:24 PM roycroft: the easiest solution would be to machine a piece of aluminium flat stock to whatever thickness i need, cut little pieces off of it, and superglue them to the ends of the existing pads
02:25 PM roycroft: there is a setting for a porter-cable 690 router
02:25 PM roycroft: an 80mm spindle is 0.320" smaller in diameter than a p-c 690
02:26 PM roycroft: so 0.160" shim stock would do the job, i should think
02:27 PM roycroft: i should learn to have low expectations and not be frustrated when dealing with customer service for consumer grade products
02:28 PM DocHopper: JT-Shop: Have you ever done any GUI stuff for python?
02:29 PM JT-Shop: yea a bunch of stuff with GTK and some with Tk early on
02:30 PM DocHopper: I'm just starting to poke around with TK today, it seems like a good idea because it's cross platform. GTK looks nice, but I'm concerned with having to port programs between windows and linux.
02:31 PM DocHopper: JT-Shop: What have you developed, and why are you all GTK now?
02:32 PM JT-Shop: https://github.com/linuxcnc/simple-gcode-generators
02:33 PM JT-Shop: http://gnipsel.com/files/mill-g-code
02:33 PM JT-Shop: http://gnipsel.com/linuxcnc/gladevcp/index.html
02:33 PM JT-Shop: http://gnipsel.com/linuxcnc/gui/index.html
02:33 PM JT-Shop: gtk is easier than tk and much easier than the other one I forget
02:36 PM hazzy: QT?
02:36 PM hazzy: I am very fond of GTK :)
02:36 PM sync: DocHopper: ime QT is the way to go if you want portability
02:37 PM DocHopper: sync: Thanks for that pointer, can I ask why?
02:37 PM JT-Shop: yea qt
02:37 PM * JT-Shop can care less about a program working in windoze
02:37 PM sync: just my experience, it just works once you understood the qt ecosystem
02:38 PM hazzy: GTK is cross platform
02:38 PM JT-Shop: yea but it is a steep climb to the first step :)
02:38 PM DocHopper: JT-Shop: I get it, but I do lots of gaming and design, so my main rig is windows.
02:39 PM DocHopper: But if python always comes with TK, why not use that?
02:39 PM JT-Shop: last game I played was an Atari and Space Invaders was my favorite
02:43 PM JT-Shop: I like gtk better
02:46 PM DocHopper: JT-Shop: Why?
02:47 PM JT-Shop: it's the easiest one for me to program in, why do you ask?
02:48 PM DocHopper: JT-Shop: Just trying to figure out into which GUI toolkit I should invest time.
02:49 PM JT-Shop: ah, I had to try them all to see what worked for me... and what works for me may not be the best for you
02:49 PM DocHopper: sync: It looks like QT is KDE and GTK is Gnome, right?
02:49 PM DocHopper: JT-Shop: I'm sure that's the best way to do it, but loooking at the sample code for each of these gui kits is really exemplifying how much I'll have to learn to use one.
02:50 PM DocHopper: So the idea of learing more than one at once is VERY unappealing.
02:51 PM sync: once you have one down the others are way easier
02:51 PM sync: they all are similar
02:51 PM JT-Shop: yup
02:51 PM DocHopper: Okay, that's good to know, but I am noticing that QT has a tighter license.
02:56 PM DocHopper: GTK looks like it would be a bear to get running on windows.
02:57 PM hazzy: https://www.gtk.org/download/
02:58 PM DocHopper: hazzy: Yup, https://www.gtk.org/download/windows.php
02:58 PM JT-Shop: dang my parts are here
02:58 PM MarcelineVQ: hooray your dang parts are here
02:59 PM hazzy: DocHopper: Your developing a cross platform app on windows?
03:00 PM hazzy: I thought you just wanted it to run on windows. Developing on windows is a pain :)
03:00 PM DocHopper: hazzy: I can develop it on windows or debian, but I want it to be able to run on nearly anything.
03:03 PM andypugh: I wouldn’t suggest using PyGTK. There is basically _no_ support available.
03:05 PM hazzy: PyGTK is only for GTK+ 2. you should not be developing anything new with that
03:05 PM andypugh: So if you want to use Python for the handlers, tough?
03:06 PM andypugh: It’s a real problem for GladeVCP on LinuxCNC.
03:07 PM andypugh: Spot the non-factory parts: https://photos.app.goo.gl/RY6tV1WnYYd41iGk1
03:08 PM hazzy: andypugh: Gtk+3 and up uses PyGObject introspection based bindings
03:09 PM Simonious: Alright brains of the internet.. I aim to do some 3D visualization of data, so say I've got an xyz coordinate and a color and I want to create a box or sphere at that location, with a space of 5x between items, where x is the diameter of the object.. How would you create this visualization? Ideally I'd like to fly through it with the ease of a CAD program including taking slices through the data
03:09 PM Simonious: image..
03:12 PM * gloops brain pings out
03:13 PM JT-Shop: the shiny nuts?
03:13 PM andypugh: JT-Shop: Well, everything that the shiny nuts are attaching, yes
03:13 PM MarcelineVQ: JT-Shop: that whole piece hanging off the dovetail iirc
03:14 PM JT-Shop: that's what I figured :)
03:14 PM hazzy: Dead give away, the part with no mounting holes in it yet :D
03:14 PM * JT-Shop checks the chicken page to see when sundown is so he have his beer with them before dark
03:16 PM hazzy: Simonious: My first thought would be to use VTK
03:16 PM hazzy: https://www.vtk.org/
03:17 PM Simonious: thanks, I'll take a look
03:18 PM hazzy: Simonious: https://lorensen.github.io/VTKExamples/site/Python/
03:21 PM Simonious: hazzy: I have the further constraint that I plan to update this data in real time and would like to be able to see those updates in the array
03:35 PM andypugh: The mounting holes are a problem, I want to engrave a degree scale round the outside. But to do that I need a high-speed spindle. But this is my high-speed spindle. As it happens I have made two complete assemblies, with the aim of maybe selling one. But that would mean drilling mounting holes in the one that I want to sell.
03:39 PM hazzy: Hmm that is a problem, you should have made three :)
03:39 PM andypugh: I did make three sets of castings, but gave a raw set to a friend.
03:40 PM hazzy: haha, so he needs to hurry up and machine his!
04:06 PM gloops: not too far archivist - https://www.ebay.co.uk/itm/Covel-surface-grinder/122789961191?
04:07 PM JT-Shop: wow I got paid tomorrow
04:08 PM Tom_L: gubermint is on it's way to collect
04:08 PM JT-Shop: I need to write myself a paycheck
04:10 PM Tom_L: if a ballscrew is 700mm is that from end to end or the actual travel?
04:11 PM JT-Shop: prob end to end
04:11 PM gloops: end to end
04:12 PM gloops: the standard chinese machined for double bearing one end single the other - knock 60mm off
04:14 PM Deejay: gn8
04:15 PM enleth: the Bridgeport's motor came back from a rebuild, it's time to get new pulleys and a belt
04:15 PM gloops: another thing they sell 300mm ballscrew with a set of 300mm linear rails
04:15 PM enleth: I'm still not sure whether to get a classic V-belt, some kind of multigroove/micro-V, or go for a toothed belt
04:16 PM andypugh: For spindle drive?
04:16 PM enleth: yes
04:16 PM andypugh: Polygroove for smoothness.
04:16 PM enleth: supposedly a toothed belt is noisy but most definitely won't slip
04:17 PM Tom_L: use rounded 'teeth'
04:17 PM JT-Shop: yea, if I ever change mine it will be to a polygroove
04:17 PM Tom_L: better grip
04:17 PM JT-Shop: it feels funny typing this in the ssh terminal systemctl status chicken.service
04:17 PM enleth: polygroove seems to be a rather expensive option, at least at my usual supplier
04:17 PM Tom_L: where are you?
04:17 PM Tom_L: uk?
04:18 PM enleth: as in, 4x the price of regular V-belts and pulleys
04:18 PM JT-Shop: take a look at the multi groove belts too
04:18 PM enleth: Poland, there's a pretty good local supplier of machine parts
04:18 PM andypugh: https://photos.app.goo.gl/LegpEzN8O9sKUWbV2 is the OEM drive on my lathe. If they can handle a lathe they won’t slip on a mill.
04:18 PM enleth: toothed belts and pulleys, on the other hand, are only slightly more expensive than V-belts
04:18 PM andypugh: (There is no secondary reduction in the head, either)
04:19 PM enleth: that's one big motherfucker of a belt
04:19 PM andypugh: I don’t relish replacing it. But I don’t currently need ot.
04:19 PM enleth: that pulley is probably bigger than the whole transmission chassis on my mill
04:20 PM Tom_L: about the same as a blower belt on a car
04:20 PM Tom_L: except they are toothed
04:20 PM andypugh: (You will also see how it is possible to fit a quite large encoder in the space vagatd by one of the change-wheel studs!
04:20 PM andypugh: (vacated)
04:21 PM enleth: ah, no, it looks bigger than it is on the photo
04:21 PM enleth: still rather big
04:21 PM enleth: anyway, I'll look for a multigroove option within my budget
04:22 PM enleth: there's also an option to use several separate V-belts in parallel on a multi-grooved (non-™) pulley
04:23 PM enleth: at least that's what I think those pulleys are for - they're marketed for a belt profile that's only used for regular belts and have more than one groove in parallel
04:25 PM andypugh: You need to get specific matched belts for those, apparently.
04:25 PM andypugh: I have never quite worked out why, but they do say that.
04:26 PM enleth: minor length differences between production runs, that would cause uneven loading?
04:26 PM andypugh: Although efficient, the twin V-belt drive can cause problems and, should the geared headstock on any V-belt drive Colchester make a knocking, rattling or rumbling sound, the cause may not be worn gears or bearings but unequal-length drive belts "fighting" each other. To check, try running on one belt to see if the headstock runs more smoothly; if it does, fit a second belt, run a chalk line across the two, start the
04:26 PM andypugh: machine for a few seconds and check that the belts are still in line; it's almost certain that they will not. Should it prove impossible to buy a pair of genuine "matched" belts, either buy a dozen standard ones (and find the two closest in length) or, even better, use a modern T-link belts.
04:27 PM andypugh: http://www.lathes.co.uk/colchester/page2.html
04:27 PM enleth: what I'm looking at right now are SPA profile belts and 3-groove pulleys
04:27 PM JT-Shop: http://www.gates.com/products/industrial/industrial-belts/heavy-duty-v-belts/micro-v-belts
04:28 PM SpeedEvil: andypugh: Err. T-link belts will have more variation than standard belts won't tehy/
04:28 PM SpeedEvil: I mean - yes, you can tune to the nearest link
04:29 PM andypugh: Apparently the internal damping makes that not matter.
04:29 PM enleth: they handle up to 35m/s which is just about the maximum speed I intend to run them at on a 200mm pulley, and there is a local manufacturer priced 3x lower than Gates
04:30 PM * JT-Shop rewinds The Court of the Crimson King and plays it louder
04:32 PM enleth: and it looks like I might be lucky and have a standard belt length fit in there just right with no tensioner
04:32 PM roycroft: i like t-link belts a lot
04:32 PM roycroft: except for the price
04:32 PM sync: enleth: I'd go for poly V
04:32 PM enleth: I'll be using TaperLock pulleys, so fitting a just-so belt on there is not going to be a problem
04:33 PM enleth: it will tension itself when I lock the tapers
04:33 PM enleth: and it looks like one of the standard lengths is about 0.5mm too short
04:39 PM Simonious: Here is an example of the kind of data display I'd like to be capable of https://snag.gy/Qulk4F.jpg
05:45 PM phipli: anyone familiar with spidev?
05:52 PM andypugh: Simonious: It might be reasonably easy with OpenGL
05:53 PM andypugh: Simonious: I think that Vismach is a fairly thin layer over OpenGL: http://linuxcnc.org/docs/2.7/html/gui/vismach.html
05:54 PM andypugh: Sourc code here: https://github.com/LinuxCNC/linuxcnc/blob/master/lib/python/vismach.py
05:57 PM nullifier: k lemme try again now that it's eveningish... anyone know of a compiled image of linuxcnc that is <512mb?
05:57 PM nullifier: for a SBC
06:30 PM andypugh: nullifier: I think you would need to start with a very minimal Linux.
06:30 PM roycroft: well, i ordered that router lift
06:30 PM andypugh: LinuxCNC itself probably fits fairly easily
06:30 PM roycroft: and it got me thinking that perhaps i should sell 80mm adapters for it
06:31 PM roycroft: since the manufacturer say it's "impossible" to use those spindles with their router lift
06:31 PM hazzy: roycroft: That is an idea
06:32 PM hazzy: Or better yet, make router lifts specifically for use with spindles
06:32 PM roycroft: i ordered the dro and the "clean sweep" rings as well
06:32 PM hazzy: nice
06:32 PM hazzy: It is a good piece of kit
06:32 PM roycroft: yes
06:33 PM roycroft: although with the accessories and shipping it is costing met about $450
06:33 PM roycroft: and i only expect to get about $150 for my old one
06:33 PM roycroft: that's a $300 deficit - i was hoping to not have to invest that much in it
06:33 PM roycroft: but i have that much cash, so not a big deal
06:34 PM roycroft: i used the paypal 6 months @ 0% financing, so once i get my new lift i'll have almost six months to get the old one sold to pay off the new one
06:34 PM hazzy: You could get a used shaper for that (with spindle), but it is not quite the same, especially for smaller work
06:34 PM roycroft: cl lowballers beware :)
06:34 PM roycroft: no, it's not
06:35 PM roycroft: and space is a concern
06:35 PM roycroft: my router table will have a footprint slightly bigger than a shaper
06:35 PM roycroft: but it will be full of storage
06:35 PM roycroft: whereas a shaper can store basically nothing - i'd have to build an ancillary cabinet to hold tooling/jigs/etc.
06:36 PM roycroft: i primarily use small cutters for dadoes, roundovers, etc.
06:36 PM roycroft: if i were making raised panels all day long every day i'd get a proper shaper or two or three
06:37 PM roycroft: besides, if i just bought a shaper i'd lose out on the "fun of the build" :)
06:37 PM hazzy: I use the BPort for raised panels with a shaper cutter, works a treat
06:37 PM BeachBumPete: I have a 3hp shaper here in my shop
06:38 PM hazzy: And a sharper is not as shiny as the INCRA stuff :)
06:39 PM roycroft: being able to hold 0.001" with woodworking machinery is nice :)
06:39 PM roycroft: except if you breathe on the work from too close you lose that precision as the wood swells up
06:40 PM hazzy: yep :D
06:41 PM CaptHindsight: nullifier: you'll have to build from scratch or try to trim Debian down to that size, it wasn't an easy task 10 years ago to get it to fit on a 600MB CD
06:41 PM roycroft: as long as it doesn't move too much before the glue-up you're fine though
06:41 PM hazzy: It is like machining plastic, it was accurate right when it came of the machine
08:13 PM CaptHindsight: nullifier: https://wiki.debian.org/ReduceDebian might be of interest
08:33 PM Tom_L: didn't jepler put it on a bbb once?
08:36 PM CaptHindsight: we built from scratch for a few ARM boards, Jepler had it on a Samsung ARM SOC board, I for get the name of it
08:37 PM CaptHindsight: oh an Odroid
08:40 PM CaptHindsight: thumb drives are cheap...
08:40 PM CaptHindsight: maybe nullifier has a board with only 512MB of flash onboard and no room for a USB/thumb drive
08:41 PM CaptHindsight: he didn't leave any details
09:16 PM nullifier: Oh...
09:16 PM nullifier: I'm here... it does have USB, I just can't boot from it
09:17 PM nullifier: http://support.advantech.com/support/DownloadSRDetail_New.aspx?SR_ID=1-MGH4R&Doc_Source=Download
09:17 PM nullifier: That's the boar
09:17 PM nullifier: d
09:20 PM nullifier: I have an Odroid-C2 incidentally... just didn't think it would be jitter free what with quad core
09:20 PM Tom_L: i think jepler had issues with it but can't tell you what
09:22 PM nullifier: yeah where these industrial PC-104 SBCs are purpose built for GPIO
09:22 PM nullifier: and lots of it
09:23 PM nullifier: the carrier it's on has some sort of FPGA breakout and a second cardflash input
09:24 PM nullifier: and a huge whack of octal buffers, etc
09:24 PM CaptHindsight: https://github.com/NTULINUX/toolchain_builder for building ARM toolchains without any magic
09:24 PM nullifier: it's actually x86
09:24 PM nullifier: baby AMD geode
09:25 PM CaptHindsight: yes, I'm familiar with the Advantech boards
09:26 PM nullifier: This is oout of a dialysis machine so I'm guessing it's rather tough
09:29 PM CaptHindsight: jepler had the odroid working with the Mesa FPGA over SPI
09:30 PM CaptHindsight: https://github.com/jepler/u3-7i90
09:31 PM CaptHindsight: I don't recall the jitter scores from old Geode boards
09:32 PM CaptHindsight: https://forum.linuxcnc.org/38-general-linuxcnc-questions/10140-latency-test-not-opening-10-04?start=10
09:39 PM CaptHindsight: the Geode board had IDE
09:40 PM nullifier: this one does as well, I just don't have a cable
09:40 PM nullifier: In fact I'm not even sure I have any working IDE spares left
09:40 PM CaptHindsight: you could try using a SATA to IDE adapter if you don't have an old IDE drive
09:41 PM CaptHindsight: I designed a bunch of Geode boards back then
09:42 PM CaptHindsight: Cyrix/AMD had some hardware virtualized in software, I forget which parts
09:42 PM nullifier: ever do anything for the transmeta units?
09:43 PM CaptHindsight: audio sounds familiar
09:43 PM CaptHindsight: we looked at transmeta but they were always behind
09:44 PM CaptHindsight: wow almost 20 years ago now
09:44 PM nullifier: I'm probably going to really super hard way to build anything... considering I have a PLC sitting right next to it
09:45 PM nullifier: it has a touchscreen though (rubs gently)
09:46 PM nullifier: Touch in 2003 wasn't cheap. Doing it well... medical implementation? pfffffffft.
09:46 PM nullifier: I forget the medical iso spec now... 13985?
09:47 PM CaptHindsight: it still sucks
09:48 PM nullifier: elo COACh III
09:48 PM CaptHindsight: even cap multitouch, unless you really like virtual screen keyboards on your phone
09:48 PM nullifier: for machines?
09:48 PM nullifier: in gloves
09:49 PM CaptHindsight: we were building tablets back then for the shop floor
09:49 PM CaptHindsight: even without gloves nobody liked virtual keyboards
09:50 PM sync: with cap touch it is not so bad
09:50 PM CaptHindsight: maybe for a few taps to dial a person up but not for any real work
09:51 PM CaptHindsight: but then again they got people used to unstable blue screen computers
09:51 PM CaptHindsight: that also slow down as they get older
09:51 PM CaptHindsight: I guess the electrons just get old or get jammed up inside :)
09:53 PM CaptHindsight: and laptops with cheap chicklet keyboards
09:53 PM sync: of course you are not going to type books on screen but for most HMI stuff they work fine
09:53 PM CaptHindsight: do you want a touchscreen keyboard for your CNC?
09:54 PM jdh: almost all my HMI's at work are touch screens. the ones that aren't are annoying because I try to touch them.
09:55 PM CaptHindsight: heh
09:58 PM CaptHindsight: nullifier: VSA was the virtual hardware
09:59 PM CaptHindsight: it would be interesting to test jitter
09:59 PM CaptHindsight: https://routerboard.com/pdf/gx1.pdf
10:00 PM sync: yes CaptHindsight
10:00 PM CaptHindsight: anything virtual usually slows down real time performance
10:01 PM CaptHindsight: jdh: what brand controls? the ones with the touch screens
10:22 PM CaptHindsight: http://pcengines.ch/ac97mot.htm AC 97 based motion control

10:31 PM CaptHindsight: ^^ single core 600Mhz cortex-M7 for a few $
10:32 PM CaptHindsight: interrupt latency as low as 20 nanoseconds
10:36 PM MarcelineVQ: doh ho ho, that was fun, my bob hasnt arrived so I hooked up a stepper+driver to an arduino for some testing
10:38 PM MarcelineVQ: the guys with put together machines must just sit and watch them move sometimes
