01:41 AM gloops: £120 notes, cost 10 maybe
01:42 AM XXCoder: huge progress but still weak
01:44 AM TurBoss: Hello XXCoder
01:44 AM TurBoss: morning
01:44 AM XXCoder: yo
01:46 AM TurBoss: I'm with a foot in beed
01:46 AM TurBoss: Gn8
01:51 AM XXCoder: night
01:53 AM gloops: https://www.etsy.com/uk/listing/470201758/screen-wooden-lacquered-handmade?
01:53 AM gloops: if thats 2.1m shes a dwarf
02:03 AM XXCoder: not really
02:03 AM XXCoder: shorter but not dwarf
02:05 AM gloops: she probably was there anyway looks shopped
02:05 AM XXCoder: lol
02:06 AM XXCoder: gonna love it when typo really mess with sentance structure.
02:09 AM gloops: wasnt!
02:10 AM XXCoder: oh thought you meant she wasnt there
02:27 AM gloops: hmm looks like ill have to re-install linuxcnc, fdisk failing on the old box it was on
02:28 AM Deejay: moin
02:53 AM IchGucksLive: morning from germany
02:53 AM gloops: morning
02:55 AM XXCoder: hey
02:55 AM Contract_Pilot: Cannot wait to get of big pharma so i can think clearly to decypher 2 VFD manuals to do th conversion hookup programming
02:56 AM Contract_Pilot: Tried but the dull pain was to anoying and no working with hi oltage while HI
02:57 AM Contract_Pilot: Anyone wana help?
02:58 AM gloops: not my line of expertise
02:58 AM Contract_Pilot: https://forum.linuxcnc.org/pathpilot/33705-making-life-a-little-simpler-new-bob-for-the-lathe#104388
02:58 AM Contract_Pilot: Gave an all call..
02:59 AM gloops: just wiring the bob to the vfd?
02:59 AM gloops: Ichs has got a video on this
03:00 AM gloops: relay for on/off, the pwm for speed, you need a 12v input to power the pwm
03:01 AM Contract_Pilot: The tormach bob bit diffrent
03:01 AM gloops: well thats where my scant knowledge ends
03:02 AM Contract_Pilot: Yea, i hadit going on the 7I76
03:02 AM Contract_Pilot: But i am adapting to a true tormach BOB
03:02 AM Contract_Pilot: they use an emmerson commander
03:02 AM Contract_Pilot: i havea WJ200
03:03 AM IchGucksLive: Contract_Pilot: let me look at it
03:03 AM Contract_Pilot: Suck I can function o this crap but my mind wonders
03:04 AM Contract_Pilot: have to be on it till the 29th ughhhh
03:04 AM IchGucksLive: do you got the qm number as they changed lots of pwm function 2006/2010
03:04 AM Contract_Pilot: Cannot even drive myself anyplace
03:05 AM Wolfmetalfab is now known as Wolf__
03:05 AM Contract_Pilot: QM#
03:05 AM IchGucksLive: Contract_Pilot: is it the Omron or hitachi
03:05 AM Contract_Pilot: Hitachi
03:06 AM archivist: he should not be helped to break stuff while on pain killers
03:06 AM Contract_Pilot: I got it about 2 years ago.
03:06 AM IchGucksLive: https://www.hitachi-da.com/produkt-details/product/frequenzumrichter-wj200/product_category/frequenzumrichter.html
03:07 AM IchGucksLive: this is a REALY good device
03:08 AM IchGucksLive: Contract_Pilot: is it the new CPE series
03:08 AM Contract_Pilot: https://www.driveswarehouse.com/WJ200-022SF-p21546.aspx
03:11 AM IchGucksLive: 3KW normal 2.2kw High duty
03:12 AM IchGucksLive: with full sps integreaded
03:12 AM IchGucksLive: 7Relays
03:12 AM Contract_Pilot: http://www.stevenrhine.com/wp-content/uploads/2018/01/20180114_011002-1024x576.jpg
03:12 AM IchGucksLive: 2 Analog in 0-10V COOL
03:13 AM Contract_Pilot: http://www.stevenrhine.com/wp-content/uploads/2018/01/20180114_011011-1024x576.jpg
03:13 AM IchGucksLive: OK so how are yoiu connected to the BOB IF
03:14 AM Contract_Pilot: No even tried to connect trying to decypher how tormachhooks to the emmerson
03:14 AM IchGucksLive: ok the Tormach controller is ?
03:15 AM Contract_Pilot: o,
03:18 AM Contract_Pilot: I will upload the schematic after it is done extracting image
03:18 AM IchGucksLive: i woudt go P24/Pin1 Forward M3
03:19 AM Contract_Pilot: The way the BOB is wired
03:19 AM IchGucksLive: O =0-10V Lto Bob PWM ground
03:21 AM IchGucksLive: P24 is 24V so relay in betwen needed
03:21 AM Contract_Pilot: http://www.stevenrhine.com/wp-content/uploads/2018/01/UM10225_15L_Slant-PRO_Manual_1217A_WEB_189-1024x663.jpg
03:21 AM Contract_Pilot: Relay is on the BOB
03:22 AM Contract_Pilot: http://www.stevenrhine.com/wp-content/uploads/2017/12/Tormach-Breakout-Board-Lathe-Top.jpg
03:30 AM IchGucksLive: prices as MOON shiners
03:30 AM IchGucksLive: same can nearly be a 5USD Board
03:31 AM IchGucksLive: with MESA 7i92M 130USD you got a high speed system
03:32 AM IchGucksLive: im off grand Childs do arrive
03:32 AM Contract_Pilot: Yea, i use a 6I25
03:35 AM Contract_Pilot: Standard bob you are not getting the tool changer code in the pic chip.
03:37 AM Contract_Pilot: Hope these are good enought..
03:37 AM Contract_Pilot: http://www.stevenrhine.com/T-BOB/
03:38 AM Contract_Pilot: Not sure if smgvbest got my message
04:09 AM Contract_Pilot: Anyone use aself hosted wordpress?
04:09 AM Contract_Pilot: and run android phone?
04:10 AM archivist: I have used/(still have one instance) wp but it is a pile of steaming
04:11 AM Contract_Pilot: Anything better
04:11 AM Contract_Pilot: my site is stevenrhine.com
04:11 AM XXCoder: steaming pile of hot choculte!
04:11 AM archivist: poooooooooooo
04:12 AM Contract_Pilot: I am trying...
04:12 AM XXCoder: pcorn
04:12 AM Contract_Pilot: so far donations have been coming in helping a bit on the content
04:13 AM Contract_Pilot: Cannot wait to get off these drugs... not eveven narcotic class
04:13 AM archivist: problem is over use of crappy libraries and js
04:13 AM Contract_Pilot: muscle relaxers make me feel drunk
04:13 AM Contract_Pilot: 29th is the day had my post op i am ding great
04:14 AM Contract_Pilot: Rather be on the pain killers
04:14 AM Contract_Pilot: but not to have ab contraction or minimilize them
04:14 AM Contract_Pilot: I sneexed ouch
04:14 AM Contract_Pilot: sneezed
04:15 AM archivist: I tend to stay on real html and css even for mobile friendly pages
04:15 AM Contract_Pilot: But word press is so easy wiziwig
04:15 AM archivist: it fails for the database stuff I do
04:16 AM Contract_Pilot: Yea, i crashed my DB once
04:17 AM archivist: I can even teach database stuff by setting an error level http://www.collection.archivist.info/searchv13.php?searchstr=bench+pd+micrometer&errlev=3
04:17 AM Contract_Pilot: I need to get clear headed and get this VFD sortd...
04:18 AM Contract_Pilot: not a DB guy
04:18 AM Contract_Pilot: http://www.stevenrhine.com/wp-content/uploads/2018/01/20180114_015524-1024x576.jpg
04:18 AM Contract_Pilot: I can Do..
04:19 AM Contract_Pilot: I wrote a code for a PIC16C56 back in the late 90's that got me sued for billions of $$$
04:19 AM Contract_Pilot: Manchester Sniffer on 1K
04:22 AM Contract_Pilot: but i had anPioneer M2 Controller inhouse
05:11 AM jthornton: morning
05:19 AM XXCoder: yo
05:33 AM jthornton: got a 61 gram egg yesterday afternoon bet it is a double yolk egg... find out in 3 hours
05:34 AM SpeedEvil: I'm waiting on delivery of my eggs, and I'm unsure if they're double yolked.
05:34 AM SpeedEvil: I don't know how cadburies gets their chickens to lay the chocolate eggs anyway.
05:35 AM jthornton: they feed them chocolate milk
05:40 AM gloops: very slight friction with one ballscrew nut
05:41 AM gloops: i.e crunchy
05:41 AM jthornton: yuck
05:41 AM jthornton: dirt or junk?
05:42 AM gloops: cant remember it being rough when i got it so probably dirt, will blast and work in some wd40
05:42 AM gloops: its only slight i can feel/hear it though
05:42 AM archivist: not wd40 !
05:42 AM gloops: why not?
05:43 AM archivist: wd wont mix with the grease in the nut
05:43 AM archivist: mix/it will wash it out
05:43 AM gloops: engine oil?
05:44 AM archivist: wind off from where it is rough, wipe the screw
05:44 AM jthornton: Water Displacer 40 is not good stuff for that
05:44 AM gloops: if it is muck it will only stay stuck in the grease
05:44 AM archivist: may be stuck on the screw
05:44 AM archivist: embedded
05:46 AM gloops: doing it in different places, slightly stiffer than the other side (not stiff by any means) and can hear something going on, again not much, worse when screw up, but still something very slight when free
05:47 AM gloops: do you see if the muck wears out or do you run it and wear the nut out
05:49 AM archivist: if muck is in the screw groove it can be wiped/cleaned, the nut is supposed to wipe the dirt anyway
05:50 AM gloops: ill run it up and down and wipe the screw a few times
05:50 AM archivist: supposed to keep them covered from crap anyway
05:50 AM gloops: surprised the lot is knackered been drilling and all sorts round them lol
05:50 AM gloops: isnt
05:54 AM archivist: wd40 is strange mix, never ever ever use it on a clock, is not a non drying oil, it will go sticky and stop it real sooooooon
05:54 AM XXCoder: yeah its not lube of any kind
05:54 AM XXCoder: its loosener and water remover but otherwise..
05:54 AM gloops: probably mostly naptha
05:58 AM phipli: how weird
05:58 AM phipli: ubuntu just froze
05:58 AM phipli: couldn't even switch to a console
05:58 AM XXCoder: if you had setup ssh you likely can connect to it
05:58 AM XXCoder: I did
05:58 AM Contract_Pilot: So tired
05:58 AM Contract_Pilot: Cannto sleep..
05:58 AM jthornton: phipli: weird
05:58 AM gloops: dont think i ever had that with mint
05:58 AM phipli: same
05:58 AM phipli: I probably should have tried sshing in
05:58 AM phipli: but it would have taken a while to get the ip
05:58 AM XXCoder: if you havent set its bit late
05:58 AM gloops: had some strange stuff when messing about with kernels
05:58 AM phipli: gloops, it is a straight regular install
05:58 AM gloops: maybe hardware?
05:58 AM phipli: only unusual thing is that it is upgraded from the last version of the independent gnome branch
05:58 AM phipli: I'd guess graphics drivers
05:58 AM phipli: because nvidia
05:58 AM phipli: I'd imagine the machine was still working
05:58 AM phipli: just not updating the screens
05:59 AM phipli: no artefacts or anything
05:59 AM phipli: anyone happen to know how to add a programmer that isn't compatible with avrdude into the arduino ide?
06:10 AM jthornton: that's above my pay grade :)
06:17 AM Contract_Pilot: I need to go hang ot at the airport.. http://www.stevenrhine.com/wp-content/uploads/2018/01/20180114_035906-1024x768.jpg
06:17 AM Contract_Pilot: things take up way to much space
06:18 AM Contract_Pilot: tried them fo ra few days no good went cold turkey oct 1st not a cig since.
06:20 AM XXCoder: slap all of em at once
06:20 AM XXCoder: heh
06:20 AM XXCoder: my mom smoked for longer than I existed
06:20 AM XXCoder: but then 4 years ago she just decided to stop and thats it
06:20 AM XXCoder: never smoked since.
06:21 AM XXCoder: whats so weird is that she tried to quit million times
06:22 AM Contract_Pilot: Yea, will power
06:22 AM Contract_Pilot: Offer up just removed them classified as drugs hahaha
06:23 AM Contract_Pilot: I have a large bottole odf USP 100% nicotine
06:23 AM Contract_Pilot: Liquid
06:24 AM Contract_Pilot: 10ML to 1oz =100MG of nicitne per X or somthing
06:35 AM SpeedEvil: https://uk.reuters.com/article/us-health-ecigarettes/switching-to-e-cigarettes-could-save-6-6-million-american-smokers-researchers-idUKKCN1C72UJ
06:36 AM SpeedEvil: 'In an analysis of potential health benefits of getting smokers to quit tobacco, the researchers found that those 6.6 million people who switched to vaping would live for a collective total of up to 86.7 million extra years.
06:44 AM phipli: so one guy discovers immortality and the rest die young?
06:56 AM XXCoder: kind oif ammortality
06:56 AM XXCoder: would live long enough to be last of species
06:56 AM XXCoder: probably anyway
06:56 AM XXCoder: depends on what direction evolution goes and cultural evolution goes
07:23 AM phipli: excellent
07:23 AM phipli: I got one of these from the bargain bin on a website a few years back : http://hkaco.com/developmenttools/images/mikro/development-tools/AVR/easyavr5a/easyavr5a_550_1.jpg
07:23 AM phipli: managed to get its proprietary (non-avrdude compatible) usb programmer working in the Arduino IDE
07:24 AM phipli: I used to have to fetch the path to the hex file and paste it into the command line
07:28 AM gloops: well boredom brought a close to that session in the garage
07:30 AM phipli: time for a cup of tea?
07:31 AM gloops: think thats it for the day, got other stuff to do as well, about a month of other stuff that hasnt been done heh, might go back to it later
07:37 AM IchGucksLive: hi
07:40 AM gloops: hello
07:41 AM IchGucksLive: ;-)
07:42 AM Tom_L: phipli, you would have to modify the avrdude source for the new programmer
07:42 AM IchGucksLive: gloops: do you rembember how asked for the 60V PSU 4Axis
07:42 AM Tom_L: the avrdude.conf contains part definitions not programmer definitions
07:42 AM gloops: cant remember really Ichs?
07:46 AM Tom_L: phipli, i take that back. the .conf looks like it may contain pinout definitons for programmers etc
08:03 AM phipli: Tom_L, the exercise was to /replace/ avrdude
08:22 AM gloops: IchGucksLive thats just given me a thought - for 4 motors i am going to need a 4 axis psu ? or can i just run 2 from the same pins
08:23 AM IchGucksLive: what steppers
08:23 AM gloops: 3nm
08:23 AM IchGucksLive: 4A
08:24 AM gloops: forgot what amps i was using, 4 amp
08:24 AM gloops: yes i think so
08:24 AM IchGucksLive: i woudt go 3x48V
08:24 AM IchGucksLive: 2x
08:24 AM gloops: so need another psu
08:25 AM IchGucksLive: or go 16A 24V
08:25 AM gloops: ive got a 60v psu but it red lights the db drivers
08:25 AM IchGucksLive: but this looses speed
08:25 AM gloops: wonder if t6650 will take 60v
08:25 AM IchGucksLive: NO
08:25 AM IchGucksLive: Rated 40V
08:26 AM IchGucksLive: 36Max
08:26 AM IchGucksLive: gloops: do you got the HSS86
08:26 AM IchGucksLive: as Redlight
08:26 AM gloops: will have to check i forgot
08:26 AM IchGucksLive: i did not see redlight for now on drivers
08:27 AM IchGucksLive: ok im off
08:28 AM archivist: you get red/green on the better drivers
08:30 AM gloops: dm826 or something
08:30 AM gloops: it is red/green, 50v - red light
08:30 AM archivist: might be a real longshine, they protect themselves
08:30 AM gloops: plus all stop
08:31 AM gloops: i got a 48-60v psu - the minimum it gives out is 54v, so no good
08:31 AM gloops: unless i could put a resistor on the circuit
08:32 AM archivist: might not regulate so well if out of its normal range, need info on the psu
08:33 AM archivist: read the drivers specs may be happy at a higher voltage
08:34 AM gloops: tb6600 is pretty useless anyway ive read, 15khz
08:35 AM gloops: i can run x and y from this psu, ill have to sort something for the z, im mainly concerned with the x atm, if all i need to do is buy a psu thats not a problem
08:36 AM gloops: shimming the screw mounting blocks has bored me to today, winding 2 screws back by hand, removing bolts, adding shim, winding back, tighten - nah not quite, wind it all back ..
08:37 AM archivist: I have a 24v(adjusted to 28+) 20A supply on my 5 axis
08:38 AM gloops: if the 48-60v was set right it would be ok, its got the cheapest variable resistor, letting 54v through to start
08:39 AM gloops: i wondered if a 10v resistor before that would work, its not my thing heh
08:39 AM archivist: there is likely a couple of series resistors to that pot,
08:40 AM archivist: there is no such thing as a 10v resistor!
08:40 AM gloops: well thats what i mean haha, how could i reduce the voltage a bit?
08:41 AM archivist: is it a chinese supply?
08:41 AM gloops: yeah
08:42 AM gloops: just needs to be under 50 for the driver to work
08:42 AM archivist: GM500-1H ?
08:44 AM gloops: s-400-60
08:47 AM archivist: just lifted the lid on this dead one, most of the bits are on a sub board with the pots near the edge and no clear R to tell you about, this one let the smoke out in a big way
08:49 AM gloops: ill get another same as the one that works with my drivers
08:50 AM gloops: ive saved 50 quid on screw mounts and brackets, which only took about 6 days to make and fit lol
09:40 AM JT-Shop: lol
09:42 AM JT-Shop: my neighbor asked me one time if I could make a housing for his riding lawn mower deck, I said sure but it will cost you $500! He was speechless for a moment or three then mumbled he could buy them for $40
09:42 AM JT-Shop: I said yep they make them by the thousands...
09:45 AM archivist: it is amusing quoting 1 off prices with tooling costs, to people who expect production prices
09:50 AM JT-Shop: most folks have no idea what it takes to make something
09:54 AM Roguish: JT-Shop: hey. i goofed up last night. broke my new probe sytlus...... $100 doh.
09:59 AM MarcelineVQ: JT-Shop: they especially don't want to hear that their product is affordable due to slave labor for some reason
10:19 AM Tom_L: 28°F ... seems like summer
10:19 AM Roguish: 52°F .. feels like winter
10:20 AM Tom_L: after the 9's and teens it feels pretty good
10:24 AM Roguish: JT-Shop: on chickens.... https://news.nationalgeographic.com/2018/01/animals-chickens-evolution-eggs-food/
10:25 AM Tom_L: maybe that's why henry....
10:26 AM Tom_L: oh wait, that sent me to the wrong link
10:26 AM Tom_L: maybe not..
10:40 AM JT-Shop: I had 3 pullets in the nest box again this morning, took an egg from the middle one when she stood up lol
10:41 AM JT-Shop: Roguish: ouch that is an expensive stylus for sure
10:52 AM Roguish: https://www.tormach.com/store/index.php?app=ecom&ns=prodshow&ref=31899
11:06 AM IchGucksLive: why is tormach preferd in the USA as it is so expensive and exclusiv
11:06 AM IchGucksLive: is it the WIN inside
11:08 AM sync: IchGucksLive: it is not really expensive compared to the other choices
11:08 AM sync: and it is new and works from the minute you get it out of the crate
11:09 AM IchGucksLive: i guess this is it
11:09 AM IchGucksLive: Plug and play
11:09 AM IchGucksLive: a closed system
11:09 AM IchGucksLive: the Dream of every destributor
11:13 AM sync: it uses linuxcnc, but who cares if it is closed
11:13 AM sync: it works
11:30 AM IchGucksLive: ok thats how THE USA works
11:34 AM Rab: IchGucksLive, because the make:r-centric startup scene is naive and easily dazzled. And because Tormach sounds vaguely german, which we associate with formidable machine tools.
11:38 AM Rab: Kidding, mostly. But there are more than a few instances of "we need to seem hip, let's throw together a 'machine shop' with $mill and $3d_printer" and Tormach has deep penetration in that market (if the proprietors don't cheap out and go for a Shapeoko instead).
11:45 AM sync: IchGucksLive: that is not how the usa works
11:45 AM sync: that is how everywhere works
11:50 AM gloops: right, 2.8 installed again
12:51 PM gloops: https://www.ebay.co.uk/itm/lathe-parts/282801063962?
12:51 PM gloops: too far for me, useful bigger changewheels
01:03 PM gloops: https://www.ebay.co.uk/itm/pillor-drill-mag-base/282801061236?
01:08 PM miss0r: Thats some pretty rusty stuff :)
01:08 PM miss0r: Have you made the pictures yet? (The weekend is crawling to an end)
01:10 PM Tom_L: he's just messin with us.... no pics no mill
01:11 PM miss0r: :]
01:11 PM Tom_L: yeah that base is pretty pitted
01:12 PM gloops: no pics yet
01:12 PM gloops: thats all good stuff! soon clean up
01:13 PM IchGucksLive: Gn8
01:15 PM gloops: ive just been fine tuning screw block, have got them pretty much as good with load on as without
01:15 PM gloops: screw blocks
01:16 PM gloops: just taking time, it will be done soon, no point going any further until its right
01:16 PM miss0r: on this 'imaginary' mill of yours ? :)
01:16 PM miss0r: I'm doing some cleaning in the shop. I've been a real slop lately
01:16 PM gloops: ill post some pics later haha, im more interested in the stuff it makes than what it looks like itself
01:17 PM gloops: plus
01:17 PM miss0r: There was a delay on my new ballscrew. The guy making it for me, had managed to miss that it was a left-hand pitch. lol
01:17 PM gloops: i know there are people who are making lesser routers, doing the best they can, i dont want to discourage them with pics of my machine
01:18 PM miss0r: :D
01:18 PM MarcelineVQ: that good huh? :>
01:18 PM miss0r: hehehe
01:18 PM miss0r: I'll bet your design beats the living bejesus out of my homebrew'n 5-axis. Which was only ever partially finished
01:19 PM gloops: finish it, we should have a working 5 axis to study
01:20 PM miss0r: if I were to finish it today, theres alot... ALOT of the design I would have to change because i've gotten smarter
01:20 PM miss0r: Plus, I'm not completely sure I would be satisfied with the tolerences of the build now
01:20 PM gloops: problem with 5 axis, no CAM software
01:21 PM miss0r: howd'ya figure people run their 5 axis? by hand? :þ
01:21 PM gloops: hand code for relatively simple objects, or mastercam
01:22 PM * miss0r runs MasterCAM X5 for most everything
01:22 PM gloops: so you either find 6k or wait for the cops
01:22 PM miss0r: I have a good friend with a large shop, who lets me use one of his lisences ;)
01:24 PM gloops: not really much profitable application for wood anyway, or not that is any more profitable for 3 or 4 axis
01:24 PM MarcelineVQ: idk about that, decorative beams/pillars could go for a lot
01:24 PM miss0r: :]
01:25 PM gloops: per hour on the table, i doubt theres much difference
01:25 PM miss0r: Damnit!... I've just added 3 sizes of allen bolts to the assortment, now I don't have enough room for the setup to make sense :-/
01:26 PM miss0r: Thoes of you who have seen some pictures of my shop, know I'm low on places to put stuff
01:26 PM MarcelineVQ: put them in the fridge door
01:27 PM miss0r: hehe... With this rate the door will fall off sometime mid next week
01:36 PM miss0r: I hate disorder in the screw & bolt department
01:36 PM miss0r: I want to open a drawer and take EXACTLY what I want in the first try
01:37 PM gloops: not going to happen to anyone with plenty of work on
01:37 PM miss0r: Well, if you have a system, you should stick to that system. but I just had to rearrange mine a less that desireable design
01:43 PM gloops: who adds putting stuff away time onto the price?
01:43 PM gloops: its all time, it all costs, but nobody charges for it
01:48 PM miss0r: I do :] I just don't fit it in afterwards
01:48 PM miss0r: I'm thinking of making the finished EDM head design round, to fit into most router setups
01:48 PM miss0r: What size is considered the stardard?
01:50 PM gloops: well 8x4 sheet is standard, you really need a 10x5 router to work them
01:50 PM gloops: or one with the capacity to cut an 8x4
01:50 PM miss0r: isn't round spindles still some sort of standard?
01:51 PM gloops: oh the spindle yeah, most are still round
01:51 PM gloops: 65mm upward
01:52 PM miss0r: Damn. That is alot bigger than I planned to make it
01:52 PM miss0r: I'll have to scrap that idea - I want it as light as possible, as it will mostly be mounted on a magbase
01:53 PM gloops: not much to make some sleeves for fitting different spindle holders
01:53 PM gloops: what use is it on a router?
01:55 PM miss0r: At some point I might want to lay out holes with it on some sort of hardened material. I'm not sure to be honnest. I just figured it couldn't hurt
01:56 PM gloops: theres one for sale here, pretty cheap atm
01:56 PM miss0r: I ordered some angular contact bearings, some high pressure axle seals & a small stepper for the rotation
01:56 PM miss0r: an edm?
01:57 PM gloops: https://www.ebay.co.uk/itm/Spark-Eroder-EDM-Machine-Die-Sinker-Hurco/322989021006?
01:57 PM gloops: got collection only though
01:58 PM gloops: it wont sell for that, could easy go over 1k id say
01:58 PM miss0r: Damn. That is pretty cheap (at the moment). If this was local I would buy it without hesitation
01:59 PM gloops: https://www.ebay.co.uk/itm/Hurco-900-M-900M-Spark-Eroder/263204670308? same machine
02:00 PM miss0r: It is cute. But what I realy need is a portable edition.
02:00 PM miss0r: And I don't like the look of the chinesium ones, and I don't like the price of the good ones
02:00 PM miss0r: So - I'm building
02:01 PM gloops: portable probably the way to go with these, lot of hassle moving the snapped stud to the machine, in many cases id think
02:01 PM fragalot: miss0r: so the same reason i'm building a mill? :P
02:01 PM fragalot: though, the chinesium ones that are nay good started at 10k
02:02 PM fragalot: and the 2nd hand ones don't fit through the door :P
02:02 PM miss0r: Somewhat the same reason I guess :]
02:02 PM miss0r: I actualy started out with a chinesium cnc. one of thoes 3040 something. Horiffic little scrap machine
02:03 PM miss0r: But I learned alot
02:03 PM fragalot: I learned a lot on QuickTech VMC's before I bought a chinesium glorified engraver
02:03 PM fragalot: and mitsubishi lathes
02:04 PM fragalot: the main thing I learned from the QT machines is that it's much easier to fix those when the controls blow up than it was to fix the mitsubishi
02:04 PM miss0r: Started my cnc stuff with one of thoes. :) I've been doing welding, cutting'n bending for two decades
02:04 PM miss0r: lol
02:05 PM fragalot: it was fun once though when the quick-change decided it should use a haimer instead of the 32mm drill bit
02:05 PM fragalot: after a batch run of 200 pcs
02:06 PM miss0r: Odd :)
02:07 PM miss0r: A buddy of mine working at a much larger place, made a mistake on a run, and spun the measuering probe up to 35k rpm. Needless to say, it exploded into a million pieces. but its no biggie, they are only like $15k
02:07 PM fragalot: whoops
02:07 PM miss0r: yeah hehe
02:22 PM miss0r: You know the feeling, when you have to order new ceramic inserts because you've run out. Only to discover, a few days later, that you have just misplaced a box of 10 ? :/
02:22 PM miss0r: Thoes are damn expensive
03:25 PM phipli: hum. My phone does that Cromaglious_
03:38 PM Deejay: gn8
03:41 PM JT-Shop: yuck snow tomorrow
03:41 PM Tom_L: yeah, it's supposed to turn nasty for a couple days
03:41 PM * Tom_L pushes it off to the east
03:43 PM * JT-Shop fires it back with the cannon
03:44 PM Tom_L: we do need the moisture, just wish it wasn't the solid kind
03:57 PM JT-Shop: looks clear and cold here from Tuesday on
03:58 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Mill_Assembly1.jpg
03:58 PM Tom_L: getting closer
03:59 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Belt_Guard.jpg
03:59 PM Tom_L: there's the lid
04:00 PM JT-Shop: looking like a mill!
04:01 PM Tom_L: got all the limits mounted
04:01 PM Roguish: Tom_L: have ya figured out how to get it all 3 axes square to one another yet?
04:01 PM Tom_L: with an indicator
04:01 PM JT-Shop: I see the Y limit looks good
04:01 PM Roguish: how about the z to the x-y plane?
04:01 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Z_Axis_Limit1.jpg
04:02 PM JT-Shop: swing that
04:02 PM Tom_L: yeah swing it with the dial in the spindle
04:02 PM Roguish: shims?
04:02 PM Tom_L: not quite as happy with the Z limits
04:02 PM Roguish: large hammer?
04:02 PM JT-Shop: yea that is the right way to mount the limits so they can't be broken
04:02 PM Tom_L: yeah i'll shim the Z column if i need to
04:02 PM Roguish: ok.
04:03 PM Tom_L: JT-Shop, yeah but if i put covers on it, they may cause it to trip
04:03 PM Tom_L: have you ever ordered acordion covers?
04:03 PM JT-Shop: on the ball screw?
04:03 PM JT-Shop: no
04:03 PM Tom_L: thought about just some neoprene sheet
04:03 PM CaptHindsight: tend to be pricey
04:03 PM Tom_L: i can get that locally
04:03 PM Tom_L: probably 1/16" or so
04:04 PM Tom_L: considered a thick trash bag :D
04:04 PM JT-Shop: my VMC has a flexible curtain for the Y
04:04 PM Tom_L: CaptHindsight there's a chinese place that custom cuts them and it looked fairly reasonable
04:05 PM CaptHindsight: 4mil bags will last quite some time
04:05 PM Tom_L: yeah
04:05 PM Tom_L: i plan to cover them with something
04:05 PM Tom_L: or that garden underlayment stuff
04:05 PM Tom_L: it's nice n thick
04:06 PM Tom_L: problem is hot chips will go right thru it
04:07 PM JT-Shop: my lathe has sliding covers that overlap
04:08 PM CaptHindsight: Tom_L: I have some really heavy vinyl coated tarp materials i can send you
04:08 PM CaptHindsight: it's for roll up covers, mil spec stuff
04:08 PM Tom_L: yeah i don't think i could bend those and make em work ok with the tools i've got
04:09 PM CaptHindsight: vinyl coated cotton duck
04:09 PM Tom_L: i'll see what i can come up with but i'll keep that in mind
04:09 PM CaptHindsight: http://www.bigduckcanvas.com/categories/vinyl-fabrics.html
04:09 PM CaptHindsight: similar ^^
04:10 PM JT-Shop: cut up someone else blue jeans lol
04:10 PM Tom_L: heh
04:10 PM Tom_L: i've got plenty of those too ragged to wear anyway
04:10 PM Tom_L: at least when she's around :)
04:12 PM Tom_L: there's a local canvas place here too i could check with them
04:13 PM Tom_L: that surplus aluminum place i go to used to have stuff like that, they still might
04:19 PM Tom_L: Roguish, i've got some videos on tramming if you're interested
04:19 PM Tom_L: (somewhere on my website)
04:20 PM Roguish: thanks. but no. just glad to see you
04:20 PM Roguish: re thinking ahead.
04:20 PM Tom_L: i figured if you brought it up you wouldn't need em
04:22 PM phipli: I swear breadboard just vanishes into thin air
04:31 PM miss0r: Cleaned the shop, send out a few bills... I think I'll call it a night
04:31 PM miss0r: See you guys around
04:32 PM phipli: night
04:32 PM phipli: oooh
04:32 PM phipli: Just remembered
04:32 PM Tom_L: cleaned the shop... hahaha he won't be able to find anything now
04:32 PM phipli: after 4 years of waiting, I get to start learning CFD properly tomorrow
04:32 PM Tom_L: cdf?
04:32 PM phipli: company said they wanted my team to start doing CFD years ago and made it a target for me every year since... then never signed off the training
04:33 PM phipli: Computational Fluid Dynamics
04:33 PM Tom_L: nice
04:33 PM JT-Shop: cool
04:33 PM phipli: it is like guessing, but with better pictures
04:34 PM * JT-Shop needs to toss out the old table saw and get a new one before he gets hurt with that old piece of crap
04:34 PM phipli: although the last thing I did before leaving on friday was refuse to do something for a "customer", so there is probably a 1% chance I start looking for a new job tomorrow instead :)
04:35 PM JT-Shop: were you nice?
04:35 PM phipli: (she demanded I do some work for her instantly at for no fee - I actually can't say "yes" because I'm bared from making commercial decisions)
04:36 PM Tom_L: it's almost always bad to work for free
04:36 PM phipli: She used to work for us (hence thinking she has special privileges) so I apologised and reminded her that I wasn't allowed to
04:36 PM Tom_L: cause they expect a warranty anyway
04:36 PM phipli: It will be difficult
04:36 PM phipli: because the account manager will just say yes
04:36 PM phipli: but the thing is, I'm not allowed to just say yes
04:36 PM phipli: and everyone more senior than me had already left
04:37 PM phipli: she wanted it that day
04:37 PM phipli: sigh. Second time she's tried forcing me to do free work in one week. I might politely ask her to please use formal contact procedures rather than contacting me directly
04:38 PM phipli: that isn't policy, but... she's pushing her luck
04:38 PM JT-Shop: aye sounds like a touchy situation
04:38 PM Tom_L: clearly she knows who's buttons to push
04:39 PM phipli: she used to work at another company where they think management means leaning on people
04:39 PM phipli: I spent 4 months seconded there and asked to be extracted
04:39 PM phipli: there were only two ways to survive - do 12 hour days, or force someone else to do 12 hour days for you
04:39 PM phipli: not a nice working environment
04:40 PM phipli: we call them "table thumpers"
04:40 PM phipli: because the managers are always slamming their fists on the desk
04:40 PM phipli: "we're not going to hire more people because overworking you guys is more costeffective"
04:40 PM JT-Shop: lol
04:40 PM phipli: lol. Sometimes they ask me to go back over there
04:40 PM phipli: I laugh
04:42 PM phipli: nice to remember once in a while, sometimes stupid bosses are better than downright nasty bosses
04:42 PM JT-Shop: life is too short for that shit
04:42 PM Tom_L: ^^
04:42 PM phipli: One day I'll be my own boss :)
04:47 PM JT-Shop: time to lock up the chickens and call it a day, talk to you later
04:47 PM phipli: speak later
05:07 PM CaptHindsight: chicken chain gang
05:08 PM phipli: put them back in the bunkhouse after a day breaking rocks?
05:16 PM CaptHindsight: place the chickens back into their safe house for the night
05:25 PM * SpeedEvil imagines witness protection program.
05:40 PM Connor: Hey Guys.. question about my VFD. It has a E-Stop input. Says it meats all safety requirements.. I'm not sure what that means.. but, when I use it.. the VFD trips because it tries to break the motor as fast as possible and I don't have a external breaking resistor..
05:41 PM Connor: What's the major difference between the E-Stop command and a normal external stop button?
05:41 PM phipli: stick a bar heater on the resistor connector
05:42 PM phipli: (don't do that unless the others say it is a good idea - I'm making it up as I go along)
05:42 PM Connor: I have a Breaking resistor to install.. it just wouldn't fit in the enclosure.. I'm just trying to understand the internal differences between the two..
05:42 PM phipli: If something stops a motor quickly it usually means it is applying a reverse voltage or short to the motor
05:43 PM phipli: American locomotive emergency brakes put a dead short over the motor
05:43 PM phipli: ruins the motors
05:43 PM phipli: but.... stops the train
05:43 PM sync: Connor: read the manual, but you can probably change the estop mechanism
05:45 PM enleth: Connor: connect the resistor outside the enclosure, hanging off the wires or whatever, just to see if it fixes the problem
05:45 PM Connor: I'm sure it will. I'll test later..
05:45 PM enleth: if it does, figure out how to mount it or get a different one that fits
05:45 PM enleth: if it doesn't, the question is moot and the problem is elsewhere
05:46 PM Connor: I probably can mount it on the back or side of the enclosure, and extend the wires..
05:48 PM enleth: the reason it trips is probably overvoltage on the DC bus
05:48 PM enleth: as it tries to feed the energy back from the motor onto the bus while shorting the bus with the braking resistor
05:48 PM enleth: but the resistor isn't there, so the bus voltage just rises without any clamping
05:48 PM Connor: It's tripping the same was is it did when I had the deacceleration time too short..
05:49 PM enleth: and the VFD trips to protect itself
05:49 PM enleth: well, same thing
05:49 PM enleth: nowhere to dump excess energy off to
05:51 PM enleth: so it stops rectifying the energy generated by the spinning load on the motor and lets it coast to a stop by itself because trying to keep braking with no resistor would fry the IGBTs
05:56 PM enleth: Connor: as for your original question - there might be no technical difference in what the VFD does for a regular stop and an e-stop, but it might be using different settings, more aggressive for an e-stop
05:56 PM enleth: so it trips sooner because the internal capacitance fills up faster to a voltage that can no longer be handled safely
05:57 PM enleth: but it's impossible to say what the manufacturer really meant by different stop types without reading the manual
05:57 PM Connor: Yea, heard that.
05:57 PM enleth: i.e. what combination of active braking and DC braking is used and how that relates to settings you can change
05:58 PM Connor: I'm shocked that it's a NO circuit and you have to close it to imitate E-Stop.. I've always been partial to NC circuits..
05:58 PM SpeedEvil: Never trust what a dictionary says about a term if it's important.
05:58 PM enleth: maybe all of that is so highly configurable and you could make "e-stop" actually slower than "regular stop", as much as that would make no sense
05:58 PM Connor: initiate not imitate.
05:59 PM enleth: one of my VFDs allows that - there are just two different sets of parameters, one used for regular stop, the other for emergency stop
05:59 PM enleth: otherwise, same setting ranges are available
05:59 PM enleth: how fast, where the DC braking takes over from active deccel, etc.
06:00 PM enleth: and obviously if active braking causes the DC bus voltage to rise too high, it will use the braking resistor to dump off the rest anyway
06:00 PM enleth: Connor: you might also want to check whether the I/O on your VFD is configurable
06:01 PM enleth: maybe the e-stop input can be switched to NC
06:01 PM enleth: look for active-high/active-low settings for the inputs
06:02 PM enleth: although there's a chance that the e-stop input cannot be configured in such a way even when other inputs can be
06:02 PM enleth: but perhaps this function can be even moved to a different input altogether
06:03 PM enleth: again, that VFD of mine just keeps a feature bitmask for each input and there is a reasonable set of defaults that assign just one function to each input (the usual fwd/rev/stop/something set)
06:03 PM enleth: but it is possible to enable more than one function per input using the bitmask
06:04 PM enleth: separately for on- and off-states
06:04 PM enleth: pretty useful to cut down on helper relays
06:05 PM enleth: so - read the manual, there's a ton of possibilites in how a VFD might be configured
06:05 PM enleth: and each vendor has different ideas
07:57 PM Alkabal: Hi all i'm new here with beaglebone black
07:57 PM Alkabal: I try to setup my board for Cortini H105 Lathe with Leadshine DM556 i have big difficulty for understand how to create my own hal + ini + tool changer
07:57 PM Alkabal: is someone able to help me from 0 ?
07:57 PM Alkabal: Best regards
08:17 PM CaptHindsight: Alkabal: using Machinekit??
08:18 PM CaptHindsight: machinekit is s fork of LCNC
08:19 PM CaptHindsight: they have their own support http://www.machinekit.io/
08:19 PM pcw_home: Since currently the Beaglebone is only fully supported by Machinekit you are probably better of asking on the Machinekit forum
08:19 PM CaptHindsight: http://www.machinekit.io/community/channels/
08:20 PM pcw_home: ( plus there are hal/ini file differences )
08:23 PM Alkabal: ok thanks at all
08:42 PM Connor: Are they're any codes or anything with regard to using Ferrules vs Spade Crimps? I'm wiring up a relay, and I like ferrules way more than spade crimps.. but, I'm not sure if it's against code or not to use them on spade style screw terminal blocks like you find on DIN mounted relays..
08:43 PM jdh: my last machine came in with mostly bare wires. The terminal blocks for the IO didn't even really have room for ferrules.
08:47 PM jdh: but, you should use ring connectors for maximum safety and annoyance
09:52 PM enleth: if something can rip a properly crimped ferrule out of a terminal, or the wire out of the ferrule, it will rip the wire out of the ring lug too
09:52 PM enleth: properly crimped means using a multipoint crimper
09:52 PM enleth: and a correct ferrule size
09:54 PM enleth: there's a problem with shitty terminals where the ferrule, being relatively incompressible and square, will cause the screw to become lopsided when tightened because the head is only supported on one side
09:59 PM CaptHindsight: Connor: code just says that the wire termination needs to match the terminal type
10:00 PM CaptHindsight: and NEC electrical code and UL apply to different things
10:00 PM CaptHindsight: outside vs inside the control cabinet
10:01 PM CaptHindsight: NEC examples https://www.mikeholt.com/instructor2/img/product/pdf/11NEC101-1076-sample.pdf
11:23 PM Connor: CaptHindsight: This is for low voltage stuff. I'm using such fine wire, I don't think I can find spade crimps that would work.. 26awg.
11:25 PM CaptHindsight: https://www.mouser.com/Connectors/Terminals/_/N-5g5u/?P=1z0j4fjZ1yzopxh&pop=3yn0m
11:25 PM CaptHindsight: http://www.newark.com/c/connectors/crimp-terminals-solder-terminals-splices/wire-bootlace-ferrules?wire-size-awg-max=26awg
11:26 PM Connor: Yea.. I have ferrules that'll work..
11:27 PM XXCoder: hey guys
11:27 PM XXCoder: guy at reprap said machinekit uses rtai and linuxcnc uses rt
11:27 PM CaptHindsight: Connor: not spade that small
11:27 PM XXCoder: said theres difference between those 2
11:27 PM XXCoder: made me wonder
11:27 PM Connor: Just not spade crimps.. so.. I'm gonna use ferrules..
11:28 PM CaptHindsight: XXCoder: HAHAHA, tell em I said so
11:28 PM XXCoder: so both is same or?
11:28 PM CaptHindsight: XXCoder: it's the other way around for machinekit and LCNC can use either
11:28 PM CaptHindsight: XXCoder: there is no RTAI for ARM, yet
11:29 PM XXCoder: ahh ok
11:29 PM CaptHindsight: #reprap is the FoxNews of IRC
11:30 PM CaptHindsight: lots of alternative facts
11:30 PM XXCoder: yeah thats why I kinda doubted it
11:30 PM XXCoder: and reprap hardware design good grief
11:35 PM XXCoder: now guy insists its other way around lol
11:36 PM CaptHindsight: yeah, lots of abused children in there
11:39 PM CaptHindsight: well the RTAI for ARM is pretty old
11:39 PM CaptHindsight: not supported on the BBB
11:40 PM CaptHindsight: it would require funded development for the BBB
11:41 PM CaptHindsight: and it wouldn't give you much benefit on the BBB
11:47 PM CaptHindsight: https://www.nxp.com/products/processors-and-microcontrollers/applications-processors/i.mx-applications-processors/i.mx-8-processors/i.mx-8-family-arm-cortex-a53-cortex-a72-virtualization-vision-3d-graphics-4k-video:i.MX8
11:47 PM CaptHindsight: ^^ this could be an interesting CPU for LCNC
11:48 PM CaptHindsight: plenty of CPU and GPU for LCNC and a HD GUI plus integrated MCU's for real time high speed stepping
11:49 PM CaptHindsight: it could even handle machine vision, edge detection, auto alignment etc
11:50 PM Cromaglious__: you know of a mesa ethernet +lcnc image for raspberry pi?
11:50 PM CaptHindsight: Cromaglious__: there's a LCNC thread about building one
11:51 PM Cromaglious__: snes usb controller pendant
11:51 PM CaptHindsight: can';t recall now if they used Ethernet or SPI to a Mesa FPGA
11:51 PM XXCoder: for lower end theres interesting board, orangepi
11:51 PM XXCoder: no realtime kernel for it though
11:53 PM CaptHindsight: you patch with preempt_rt
11:54 PM CaptHindsight: we ran LCNC on the orangepi
11:54 PM Cromaglious__: hmmm erthernet goes thru udb, spi doesn't
11:54 PM XXCoder: oh how did it run
11:54 PM XXCoder: whats its jags like or latency
11:55 PM CaptHindsight: Cromaglious__: yeah, the RPi has ethernet over USB so they used SPI to the FPGA
11:55 PM CaptHindsight: I always for that the RPI has USB ethernet
11:55 PM CaptHindsight: for/forget
11:56 PM CaptHindsight: XXCoder: it was fine, it just needed work on the software rendering since they don't supply GPU lib source
11:57 PM CaptHindsight: you have to use software rendering on the extra CPU cores
11:57 PM CaptHindsight: it was real time on one CPU core, non-real on the 2nd CPU core and video on the 2 extra CPU cores
11:57 PM XXCoder: not too bad
11:59 PM CaptHindsight: we could have easily gotten video working well if they supplied Mali lib source
