12:39 AM roycroft: our heat watch for tomorrow has been upgraded to a heat advisory
01:08 AM Crom: yey neodynium 1/2" magnets with hole showed up
01:44 AM XXCoder: roycroft: sucks
01:45 AM XXCoder: Crom: magnet donuts? ;) was it yummy
02:40 AM Deejay: moin
02:42 AM XXCoder: hey
02:45 AM Deejay: :)
04:21 AM charlesh: Looking for some help wiring a hitachi wj200 vfd. The analog input works for the speed control (0-10v), however I am stumped about the fwd/run wiring
04:22 AM charlesh: I am using a mess 7i76e
04:22 AM charlesh: 24v field I/O
04:35 AM TurBoss: morning
04:35 AM XXCoder: yo
04:35 AM TurBoss: hello XXCoder
04:35 AM Gene_home: yo
04:40 AM Gene_home: what are the good stepper drivers recommended from aliexpress?
04:41 AM TurBoss: none
04:41 AM TurBoss: :D
04:41 AM Gene_home: what is your choice?
04:42 AM TurBoss: no was joking
04:42 AM TurBoss: sek
04:43 AM TurBoss: leadshine m542 could be good
04:43 AM XXCoder: cheap tb6600 is pretty effective
04:43 AM TurBoss: that too
04:44 AM XXCoder: dont bother with tb6560, it wasnt good experence for me in least. though it works if less demending or something dunno
04:45 AM TurBoss: XXCoder : did you saw the youtube streaming?
04:45 AM TurBoss: https://youtu.be/or2kkY0DgpU
04:45 AM TurBoss: :)
04:45 AM TurBoss: turbospam
04:45 AM XXCoder: I did see one but not sure if you meant that one - about spacex
04:46 AM XXCoder: looking
04:46 AM TurBoss: :)
04:46 AM XXCoder: uh music or something?
04:46 AM TurBoss: yes
04:46 AM XXCoder: because just a picture is VERY dull to me
04:46 AM TurBoss: dull?
04:46 AM TurBoss: sorry i don't understand
04:46 AM XXCoder: yeah to me its just a picture. lol
04:47 AM XXCoder: i'm deaf
04:47 AM TurBoss: its a pic
04:47 AM TurBoss: is a music stream
04:47 AM XXCoder: and I am deaf. lol
04:47 AM TurBoss: ok
04:47 AM TurBoss: so no sound?
04:47 AM XXCoder: I havent heard anything for last 41 years
04:47 AM TurBoss: oh
04:48 AM TurBoss: sorry didn't know what "deaf" means
04:48 AM TurBoss: now english speaker
04:48 AM TurBoss: *not
04:48 AM XXCoder: ahh
04:48 AM TurBoss: I did the mpg
04:48 AM XXCoder: anyway its genetic defect, nerves simply failed to connect
04:49 AM XXCoder: so techinically my ears work
04:49 AM TurBoss: sad...
04:49 AM XXCoder: why?
04:49 AM TurBoss: well i'm sorry
04:50 AM XXCoder: nah dont be :P
04:50 AM TurBoss: :)
04:50 AM TurBoss: https://youtu.be/jq_bu8iFJ6A <--check this
04:51 AM XXCoder: thats awesome
04:51 AM TurBoss: its over serial
04:51 AM TurBoss: :D
04:51 AM TurBoss: and a python comp
04:51 AM XXCoder: so no latency isses period
04:51 AM TurBoss: no
04:51 AM TurBoss: mcu uses interrupts
04:52 AM TurBoss: and serial is 1000000bps
04:52 AM XXCoder: way overkill really. so serial eh
04:52 AM XXCoder: not bad
04:52 AM XXCoder: whats the knob?
04:52 AM TurBoss: a alps encoder
04:53 AM XXCoder: theres pretty cheap encoder jog wheels out there
04:53 AM XXCoder: like $15
04:53 AM TurBoss: this was 1€
04:53 AM TurBoss: :D
04:53 AM XXCoder: indeed
04:53 AM TurBoss: no
04:53 AM TurBoss: 3
04:53 AM TurBoss: :)-
04:53 AM TurBoss: so its encoder -> teensy DRO -> serial
04:54 AM TurBoss: the displayed values are read from linuxcnc
04:54 AM XXCoder: I like the dro too
04:54 AM TurBoss: thanks
04:54 AM TurBoss: :D
04:54 AM TurBoss: the displays are from a weigh measurement equipment
04:54 AM TurBoss: recocled
04:54 AM TurBoss: *recicled
04:56 AM TurBoss: did you print the ship?
04:58 AM XXCoder: sadly no
04:58 AM TurBoss: hehe
04:59 AM XXCoder: im considering just farm that out lol
04:59 AM TurBoss: farm?¿
05:00 AM XXCoder: let others worry about tough as hell thing
05:00 AM XXCoder: ah lingo lol
05:00 AM XXCoder: "farm it out" means give task to someone else to pay money for services
05:00 AM XXCoder: uncommon slang really
05:00 AM TurBoss: ahhhh
05:00 AM TurBoss: :D
05:01 AM XXCoder: I wanted it to be done with SLS
05:01 AM XXCoder: but dang are minium orders high lol
05:01 AM TurBoss: stereolithographi?
05:02 AM XXCoder: laser burning powder plasic to fuse em by layers to make object
05:02 AM TurBoss: ok
05:02 AM XXCoder: laser sinering, forgot what first word is
05:06 AM XXCoder: bleh still cant do crap
05:30 AM MacGalempsy: yo
05:31 AM XXCoder: hey mac
05:31 AM XXCoder: whats up
05:35 AM MacGalempsy: a slowww night
05:35 AM XXCoder: yeah?
05:36 AM MacGalempsy: yeah. we are drilling 12ft/hr
05:36 AM MacGalempsy: and have another 8500ft left
05:36 AM XXCoder: long night allright
05:43 AM jthornton: morning
05:43 AM XXCoder: yo
05:44 AM jthornton: deepest hole I worked on was a tad over 5 miles down
05:44 AM Gene_home: looking for a good diy laser cutter project, any recommendations?
05:44 AM XXCoder: diy dunno but aliexpress has tons of pretty cheap ones.
05:45 AM archivist: diy fire hazard
05:45 AM XXCoder: like $200 or so. dont buy $80 ones that use cd drives for mechisms
05:45 AM XXCoder: arch pretty much yeah
05:47 AM XXCoder: LOL RPNOS it's an app for ti-84 that allows reverse polish notation
06:00 AM XXCoder: Gene_home: honestly you have 2 choices if you want laser CUTTER - expensive machines or that chinese blue box one
06:00 AM XXCoder: you'll need to essentally do maintance work on chinese special in order to make it work, and once it works it works ok.
06:02 AM jthornton: hmmm one hen stayed on the roost and didn't go out with the others
06:02 AM XXCoder: brooding?
06:02 AM phipli: too young
06:02 AM phipli: and they brood in boxes
06:02 AM phipli: not perches
06:02 AM XXCoder: ah
06:02 AM jthornton: yea 11.5 weeks old
06:03 AM phipli: jthornton: make sure she has water and food
06:03 AM jthornton: she just went out 10 minutes behind the rest
06:03 AM phipli: check her crop
06:03 AM phipli: make sure it isn't full first thing in the morning
06:04 AM phipli: how much grass do they get?
06:04 AM phipli: (if any)
06:04 AM phipli: and do any of them eat wood chips?
06:04 AM jthornton: they have a play yard that has grass and other green things
06:04 AM jthornton: I let them in the play yard a few times a day
06:05 AM phipli: can you tell her apart?
06:05 AM jthornton: no, it's one of the RIR's
06:06 AM phipli: tomorrow morning, when they first come out, check all the RIR's crops to see if they're empty
06:06 AM phipli: otherwise I wouldn't worry too much - most problems are egg related and they're too young for that :)
06:07 AM jthornton: yea we have another 5 weeks or more before any chance of eggs
06:07 AM phipli: Crop is off centre to the right when you hold them facing away from you
06:07 AM phipli: on their breast
06:07 AM phipli: easy to feel how full it is
06:10 AM jthornton: when you power up a nano does it run the setup code each time?
06:12 AM phipli: yeah
06:20 AM jthornton: can you have more than one device on the I2C buss?
06:23 AM jthornton: a google search for oled ds3231 nano says yes
06:23 AM Deejay: normally yes
06:23 AM Deejay: up to 128 or so
07:26 AM phipli: jthornton: yes, as long as they have different device addresses
07:29 AM phipli: the ds3231 has a fixed address of 0x68 I think. What are you planning to use with it?
07:30 AM phipli: reamers arrived yesterday - feels like the tapers were in good nick - ran the reamer in the taper and re-checked
07:31 AM phipli: still an alignment issue
07:34 AM archivist: is the head spindle axis parallel with bed
07:34 AM archivist: is the head on dowels or just "placed"
07:36 AM phipli: vertical alignment archivist
07:36 AM phipli: ticking things off the checklist
07:36 AM phipli: something fouling the tapers was this mornings check :)
07:36 AM phipli: headstock has a large pivot / clamp bolt
07:37 AM phipli: then two small bolts either side of the spindle near the chuck
07:37 AM jthornton: I was trying to add an oled
07:37 AM phipli: did it work or did you have issues?
07:37 AM phipli: most likely issue is conflicts in the libraries
07:38 AM jthornton: it worked by itself but not with the ds3231
07:41 AM archivist: phipli, that design needs careful adjustment of the head to align with the tail, put a dti on the carriage amd measure a bar in a chucl/morse collet
07:42 AM archivist: 2 settings 180 degrees apart to remove collet/chuck error
07:50 AM Tom_itx: JT-Shop, i2c are addressable
07:53 AM Tom_itx: do you have a pullup on SDA?
07:54 AM jthornton: no
07:54 AM Tom_itx: try a 10K
07:54 AM Tom_itx: i have a 1k on one
07:54 AM jthornton: I have memory problems with all the libs and run out of space lol
07:55 AM Tom_itx: that's ardweenie
07:55 AM Tom_itx: code it in c and you won't :D
07:57 AM archivist: assembler!
07:57 AM Tom_itx: on a good note, my mill still works after updating the OS
07:57 AM jthornton: cool
07:57 AM Tom_itx: archivist, well yeah but i wasn't trying to be mean
07:57 AM archivist: :)
07:57 AM jthornton: I have peter north's assembler book somewhere lol
07:57 AM Tom_itx: same here
07:57 AM Tom_itx: and some old cookbooks etc
07:57 AM Tom_itx: i have the avr asm pdf if you really want it
07:58 AM Tom_itx: http://tom-itx.no-ip.biz:81/~webpage/pdf/atmel/AVR_instruction_set.pdf
08:07 AM phipli: AVRs were optimised for compiled C
08:07 AM phipli: so they're not as bad as other platforms
08:07 AM phipli: with compiled code
08:08 AM phipli: but obviously nothing compares to a tight asm loop for speed
08:08 AM phipli: but... as he is trying to drive two I2C devices and doing graphics...
08:20 AM phipli: archivist, jthornton : poking the internet, given the size of the misalignment and the fact that thing is level enough etc etc... and its age and unknown history...
08:20 AM phipli: excessive wear in spindle bearings?
08:20 AM phipli: they're the single split type
08:21 AM phipli: so while there isn't any play, that would be because you just clamp it up a bit more
08:22 AM jthornton: what's the link to the photos?
08:23 AM phipli: http://gallery.elephantandchicken.co.uk/#!album-1
08:23 AM phipli: nothing with the headstock in pieces though
08:24 AM phipli: and this for the alignment : http://elephantandchicken.co.uk/Lathe/Headstock-Tailstock.jpg
08:26 AM phipli: archivist: http://iloapp.elephantandchicken.co.uk/data/_gallery/public/1/149746657666398300_resized.jpg
08:29 AM jthornton: the welded up gear suggests it was dropped or something fell on it, try shimming the headstock level with the bed
08:30 AM phipli: breaking that gear is quite a common operator error on those I believe
08:31 AM phipli: I forget what does it - either engaging power with the gears in a certain position, or the drive pin not being in the correct place
08:32 AM phipli: the bearings might be two part actually...
08:32 AM phipli: phosphor-bronze
08:32 AM phipli: I might have a look. it isn't aligned anyway :)
08:32 AM phipli: measuring the spindle isn't too bad, what is the best way of measuring the OD?
08:34 AM phipli: ah. Lathes.co.uk says the spindle is 1.125'
08:34 AM phipli: *"
08:34 AM phipli: heh
08:34 AM phipli: 12.125 inch spindle would be overkill
08:34 AM jthornton: OD of the spindle?
08:35 AM phipli: bushes
08:35 AM phipli: bearings
08:36 AM jthornton: micrometer if you have one
08:37 AM jthornton: are the bearings 1 piece?
08:37 AM phipli: they might be 2 part
08:37 AM phipli: I haven't seen them
08:37 AM phipli: either 2 part, or 1 part with a cut
08:37 AM phipli: OD off the bearings is tricky - it would be best to get it off the bearing seat
08:38 AM jthornton: breakfast time here :)
08:38 AM phipli: I guess measure off the bearing, then get a couple of disks at the nearest imperial sizes
08:38 AM phipli: and test them?
08:38 AM phipli: we had eggs and bacon for breakfast
08:38 AM phipli: never short of eggs, even with only two birds
08:54 AM JT-Shop: what are you trying to measure?
08:56 AM phipli: bearing OD - if they're split they might move when I take them out
08:58 AM phipli: or would it be too small to worry about
09:04 AM JT-Shop: dunno what knowing the bearing OD would do to help
09:05 AM phipli: replacing them
09:07 AM JT-Shop: is there play between the spindle and the bearings?
09:08 AM JT-Shop: or are you thinking if they are split that they are worn down thus lowering the spindle?
09:08 AM phipli: exactly
09:08 AM phipli: (the latter)
09:08 AM JT-Shop: take them out and look at the inside if worn it should be easy to spot
09:08 AM phipli: they're the softest part in the machine
09:08 AM phipli: yeah
09:08 AM phipli: thin on one side...
09:08 AM JT-Shop: aye
09:08 AM phipli: might do that now
09:09 AM phipli: (got some whitworth spanners in the post yesterday - yay, no more adjustables)
09:10 AM JT-Shop: whitworth different than inch spanners?
09:10 AM phipli: whitworth was our first standardised system for bolts
09:11 AM phipli: inches yes
09:11 AM phipli: https://en.wikipedia.org/wiki/British_Standard_Whitworth
09:11 AM phipli: oooh, fanch
09:11 AM phipli: *fancy
09:11 AM phipli: "World's first national screw thread standard"
09:12 AM phipli: "American Unified Coarse was originally based on almost the same Imperial fractions"
09:12 AM archivist: I was outside for a bit getting a display ready for local railway station open day
09:13 AM phipli: mainline or heritage?
09:13 AM archivist: was a branch, closed in 1960's
09:13 AM archivist: Rolleston on Dove
09:14 AM archivist: when the rails were lifted I went for a walk "rescued" two bridge plates and a gate sign
09:15 AM archivist: damned if I can remember which bridge!
09:15 AM JT-Shop: yea I know what a whitworth thread is, I got some equipment from Taiwan that had some on it
09:16 AM JT-Shop: of course to properly fix the lathe you need to put some smd's under the bearing to raise it up :)
09:17 AM archivist: is the spindle sloping (bearings) or parallel
09:18 AM archivist: I have a 1" reamer I got when I did my Zyto lather
09:18 AM archivist: lathe
09:19 AM archivist: phipli, http://www.rolleston-on-dove-station.co.uk/prototype.html
09:20 AM archivist: his map misses a bridge or few out
10:01 AM archivist: phipli, the bearings in the tyzack were simple glacier split bearings, yours may be similar
10:27 AM Genew: yo
10:27 AM Genew: how do I do a windows capture in linux?
10:27 AM Genew: window capture
10:30 AM archivist: accessories take screenshot
10:36 AM Genew: archivist: many thanks!!!
10:40 AM phipli: sad LOL
10:40 AM phipli: just a minute
10:41 AM phipli: archivist: video to show you...
10:42 AM phipli: Genew: if you're using mint, pressing printscreen with the alt key captures just a window
10:43 AM phipli: same as the little known feature on windows
10:43 AM phipli: that saves cropping
10:51 AM phipli: archivist: JT-Shop : http://elephantandchicken.co.uk/Lathe/spindle.mp4
10:51 AM phipli: told you it was bent
10:54 AM Topy44: my client just went weird, if anyone answered to me please repeat...
10:56 AM phipli: when did you ask?
10:57 AM Topy44: ah. i guess it went weird before i asked. :)
10:57 AM Topy44: i asked if anyone can identify this tool: http://dump.t44.org/XnView_-_%5BIMG_20170624_171028.jpg%5D_2017-06-24_17-10-42.png
10:57 AM Topy44: its made in germany by saltus, was probably quite expensive once. i first thought it was some kind of key, but its too massive and the outer surfaces are not machined.
11:03 AM archivist: drain plug tool, plumbers
11:04 AM archivist: phipli, does not play on this box, other box struggles, too jumpy to see
11:05 AM archivist: other box is short of ram
11:09 AM Bagi: Hi all,
11:10 AM Bagi: my config is 7I92 with Benezan Bit File. is it right, that IO07 ( Pin 17) can only be used as input ?
11:12 AM phipli: archivist: try saving it to desktop?
11:12 AM phipli: just a mp4
11:13 AM archivist: its the amount of memory in the pc how does desktop make a difference
11:16 AM phipli: less overheads and more choice of player application
11:16 AM archivist: choice of one on that box
11:22 AM archivist: trouble these days is the expansion into memory takes huge chunks and a mere 1 gig free on a 32bit box just cant do it
11:24 AM phipli: surprised with a 14 second video
11:25 AM phipli: I'm on the phone - but will tweak it in a bit
11:25 AM archivist: I probably see about 3 secs
11:26 AM archivist: DTI when it was still in the head would have given a real number to the bend
11:28 AM pcw_home: Bagi: pin 17 (GPIO7) is defined a a PWM output (for spindle control) in the Benezan bitfile
11:29 AM pcw_home: it can be used as a GPIO input or output if the PWM function is not enabled
11:30 AM phipli: archivist: will do - just had it out anyway because I was checking the bearings
11:30 AM phipli: front one has warn down about 0.2mm
11:31 AM phipli: back one is down about 0.1mm
11:31 AM phipli: explains the droop
11:31 AM JT-Shop: so that explains the spindle nodding down
11:31 AM phipli: yup
11:31 AM archivist: a bit aged
11:32 AM phipli: almost 8thou wear on the front one
11:32 AM archivist: put the front upside down
11:33 AM JT-Shop: so the spindle is bent as well?
11:33 AM phipli: is that ok with a single split?
11:33 AM phipli: JT-Shop: yeah
11:33 AM phipli: thought it was
11:33 AM JT-Shop: can you straighten it?
11:33 AM phipli: I've not measured it yet
11:33 AM phipli: just checked it while it was out
11:33 AM archivist: or find a man with a press and the skill
11:33 AM JT-Shop: at least you know what is wrong now
11:33 AM phipli: EVERYTHING :)
11:34 AM JT-Shop: yea we used to straiten motorcycle forks with v blocks and a press
11:34 AM phipli: heh
11:34 AM phipli: I could put the wonky bullgear back on 180 deg out
11:34 AM archivist: seen a video and straightened a few bits
11:34 AM phipli: and run it with the backgear engaged...
11:34 AM phipli: that would reverse the force that probably bent it in the first place
11:35 AM JT-Shop: the scary part is bending it past straight to get it straight
11:36 AM JT-Shop: can you get new bearings for it?
11:36 AM phipli: they're not complicated
11:36 AM archivist: make new
11:36 AM phipli: any shop could turn them up
11:36 AM JT-Shop: do they have X shaped oil grooves on the inside?
11:36 AM archivist: even you
11:36 AM phipli: single flanged plain bearings
11:37 AM phipli: JT-Shop: nothing at all
11:37 AM phipli: archivist: don't have a lathe :)
11:37 AM JT-Shop: just a hole for the oil
11:37 AM phipli: JT-Shop: nope
11:37 AM phipli: didn't see one
11:37 AM phipli: guess it comes in through the split
11:37 AM JT-Shop: I saw a hole in the bearing cap for I assume oil
11:37 AM phipli: there is
11:38 AM JT-Shop: does it have a groove in the cap?
11:38 AM phipli: I've not had them out out
11:38 AM phipli: just measured the protruding bit on the unflanged end
11:39 AM phipli: my bad
11:39 AM phipli: there is an oil hole
11:39 AM phipli: and also a pin to stop them spinning
11:39 AM phipli: so a little bit more complex
11:39 AM phipli: but not terrible
11:39 AM JT-Shop: what is the shaft size?
11:39 AM phipli: 1.125"
11:40 AM phipli: material thickness on bearing was 1/8th
11:40 AM JT-Shop: a bit odd for a stock bearing so you would have to make them
11:40 AM phipli: or not
11:40 AM phipli: what was it...
11:40 AM phipli: yes. was 1 8th
11:41 AM JT-Shop: http://www.bronzebushings.com/ff-1314-3-oil-impregnated-bronze-flanged-1-125-id-x-1-375-od-x-1-25-oal-x-1.html
11:41 AM phipli: so OD is 1.375"
11:41 AM JT-Shop: seems bearing houses have them
11:41 AM phipli: ... like you say
11:42 AM phipli: nice
11:43 AM JT-Shop: is that the bearing?
11:44 AM phipli: they have a gap in them (could make) and I've not checked the flange thickness, but close enough I'd say
11:47 AM archivist: JT-Shop, were you going to vote ?
11:54 AM phipli: archivist: thanks for getting me to actually measure it!
11:54 AM phipli: it is straight!
11:54 AM phipli: the bore inside (the rough bore, not the taper) is off centre
11:55 AM phipli: meaning the weight isn't central
11:55 AM phipli: also, if the bearings are identical, if I make a new oil hole in each, I can swap them and get a second life out of them?
11:56 AM phipli: although I'll be clamping a cast iron thing tighter than perhaps I'd like to
11:57 AM archivist: I felt the clamping made a new pair the better option too
11:58 AM archivist: I got lucky Tyzack was still around in the 1970s and manages to buy new old stock
12:03 PM JT-Shop: vote on what?
12:04 PM archivist: git
12:04 PM archivist: github
12:05 PM JT-Shop: hmm I thought I joined that channel
12:06 PM archivist: you did on your other client
12:09 PM jthornton: I forgot lol and started wandering around the shop cleaning up
12:13 PM * jthornton takes part in his favorite weekend treat... a nap
12:14 PM roycroft: blah
12:14 PM roycroft: the updated forecast now calls for a high of 39 today
12:18 PM * roycroft is definitely going to the coast in a bit
12:19 PM IchGucksLive: hi
12:19 PM howto: hi
12:19 PM howto: solved the correctnes of axis travel
12:20 PM IchGucksLive: thats how it shoudt be
12:40 PM IchGucksLive: im on the data analysys of the harvest
12:41 PM IchGucksLive: i did 84 trucklöoads
12:41 PM IchGucksLive: total 420
12:41 PM IchGucksLive: total tonnes in the bioelectric 4000
12:42 PM IchGucksLive: and still 200 Acrers of corn to go in october i guess
12:42 PM IchGucksLive: so 12000tonnes of SUN power thisyear
12:44 PM IchGucksLive: hi almostworking
12:44 PM IchGucksLive: you are on that for month now
12:44 PM IchGucksLive: change to itsdone
12:49 PM howto: IchGucksLive browser just crashed
12:49 PM IchGucksLive: i swa it
12:49 PM IchGucksLive: did you get the g-code ?
12:49 PM howto: nope exactly on the pastebin page it failed...icouldnt download it
12:50 PM howto: send link again
12:50 PM IchGucksLive: link is expirerd
01:00 PM phipli: archivist: the bearings doing easily slide out, even if I pinch them slightly
01:00 PM phipli: any thoughts?
01:07 PM Topy44: [17:33:17] <archivist> drain plug tool, plumbers
01:07 PM Topy44: thanks!
01:07 PM Topy44: can't actually find anything it fits for though, but at least i now know it is a plumbers tool :)
01:30 PM georgegw: hello
01:33 PM IchGucksLive: hi georgegw
01:34 PM IchGucksLive: im off to BBQ
01:34 PM IchGucksLive: its best weather in germany
01:34 PM howto: bye and bon appetit
01:34 PM IchGucksLive: and meat is smelling towards the CNC
01:34 PM howto: yeah
01:34 PM howto: in deed
01:34 PM georgegw: i am new in linux cnc.. and i have a prob with my picstep v4 control board.... , i cant find a way from hal...or from stepconfig to create a enable signal for each axis for 3 axis system... kcam windows program has a command for enable axis with step, i want something in emc...
01:35 PM JT-Shop: phipli: bearings stuck in base or cap?
01:36 PM phipli: there is an alignment pin and it doesn't seem to be withdrawing
01:36 PM phipli: or something else catching
01:38 PM TurBoss: isn't amplifier enable what you are looking for georgegw?
01:38 PM TurBoss: ah you mean for each axis
01:42 PM georgegw: yes different for axis
01:42 PM georgegw: like kcam prog from windows.... enable signal when axis steps run
01:43 PM georgegw: i try some commands in hal txt... but only errors... :D
01:44 PM TurBoss: net Xen => parport.0.pin-01-out
01:44 PM TurBoss: i found this
01:44 PM georgegw: maybe a synch with classicladder and hal... when, axis.0.joint-vel-cmd <> 0 then energize one output
01:44 PM TurBoss: http://linuxcnc.org/docs/html/config/stepper.html
01:44 PM TurBoss: here
01:45 PM georgegw: i try this.... but the signal goes on with machine on.... and dont goes off if one axis stops
01:45 PM georgegw: and the motors burn!
01:46 PM georgegw: picstep v4 board has the LMD18245
01:46 PM TurBoss: why motors burn?
01:46 PM pcw_home: if you disable step drives when you stop, you will very likely lose steps...
01:46 PM TurBoss: I have no problems with havind the motors enabled
01:47 PM TurBoss: ^
01:47 PM TurBoss: also that
01:47 PM georgegw: because the lmd ic has a brake in 10 pin
01:47 PM georgegw: and it want to be 0
01:47 PM georgegw: and 1 with step pulse
01:49 PM georgegw: thanks for attention... i dont have more time, bye!
01:51 PM TurBoss: that remembers me that I have the motors enabled :D
01:53 PM Genew: anyone have the link for a desk mounted arm with an electric/neumatic tap, allows you to auto tap holes perpendicular to the table with one hand
01:54 PM Genew: diy item for $75-$100
02:02 PM Genew: http://www.cnccookbook.com/CCTappingArm.htm
02:10 PM LeelooMinai: Genew: I would just bugger it and use a long tube attached to a celing beam:)
02:16 PM Genew: sure wish there was a BOM for that......
02:35 PM Bagi: pcw_home: thanks. i have removed spindlecontrol from the hal and now i can set gpio07 as output and Linuxcnc starts without error.

04:33 PM phipli: one for archivist
04:34 PM phipli: https://www.youtube.com/watch?v=nFxXqr-6Sdc
04:35 PM JT-Shop: now I'm wondering how to protect my nipple water system when it freezes
04:36 PM JT-Shop: now that's a steam engine
04:36 PM JT-Shop: does it have a big flat belt pulley on the other side?
04:37 PM phipli: looks like a chain drive
04:38 PM hazzy: That thing it pretty fast :D
04:38 PM phipli: tracks!
04:38 PM phipli: :)
04:38 PM phipli: that thing does look awesome
04:39 PM JT-Shop: a lot of the ones over here only drove to a work site and then set up a flat belt to run equipment
04:39 PM JT-Shop: we have one that still runs once a year at the harvest fest
04:39 PM phipli: the PTO?
04:39 PM phipli: yeah
04:40 PM JT-Shop: yea
04:40 PM phipli: even Diesel tractors sometimes had a large flat belt PTO
04:40 PM phipli: that one seems to be a log hauler
04:40 PM phipli: don't know if it has a belt drive on the other side
04:40 PM phipli: thought you meant for traction
04:41 PM JT-Shop: they used mules over here to haul logs out of the woods :)
04:41 PM JT-Shop: so I'm wondering what about my water system and winter... it does freeze here from time to time
04:42 PM malcom2073: Those guys need power steering heh
04:42 PM phipli: a large volume of water takes quite a while to freeze
04:42 PM phipli: how big is the tank?
04:42 PM phipli: if you're only worried about a few days sub freezing
04:42 PM phipli: and have a good few gallons - just keep it topped up
04:42 PM JT-Shop: the design now is 5 gallons but the pvc part where the nipples are is in question
04:43 PM phipli: insulation is usually enough here
04:43 PM phipli: how cold does it get?
04:43 PM XXCoder: JT-Shop: I remember something about rotating water system
04:43 PM XXCoder: it loops little amount of water so pipes and tank cannot freeze
04:43 PM JT-Shop: http://www.usclimatedata.com/climate/poplar-bluff/missouri/united-states/usmo0713
04:44 PM XXCoder: it loops back inside more insulated area so that part dont freeze
04:44 PM XXCoder: not too sure on accuracy of my memory though.
04:45 PM phipli: -3 minimum
04:45 PM phipli: insulate the tank and you'll be fine
04:46 PM XXCoder: http://sciencing.com/keep-solar-hot-water-freezing-2289.html
04:48 PM JT-Shop: I think I'll change my plan and put the nipples in the bottom of the bucket
04:49 PM XXCoder: isnt heat rise so top would stay warm longer when isulated?
04:49 PM JT-Shop: http://1.bp.blogspot.com/-afdqy4nCU88/UQFND3hOxJI/AAAAAAAABaI/AQOUEP3mrHQ/s1600/100_3339.jpg
04:49 PM JT-Shop: was thinking about something like this
04:50 PM JT-Shop: I have an immersion heater for a dog bowl I think
04:50 PM phipli: what about one of these :
04:50 PM phipli: https://images-na.ssl-images-amazon.com/images/I/51eAkVWrR7L.jpg
04:51 PM phipli: use them for heating brewing beer
04:51 PM phipli: (might have a couple of them...)
04:51 PM JT-Shop: I could wrap heat tape around the bucket but the immersion heater I just toss it in and put the lid back on
04:53 PM phipli: the volume you're talking about - it would take days to freeze much anyway at -3
04:53 PM phipli: paint it black and stick it in the sun
04:54 PM JT-Shop: if I use a 3/4" pvc distribution pipes they will freeze overnight
04:54 PM phipli: insulation?
04:54 PM phipli: back home our water was un-metered, so we used to just leave it running a bit...
04:55 PM phipli: when we were kids we'd run a piece of string from the tap to make icicles
05:01 PM JT-Shop: https://simplethrift.files.wordpress.com/2014/04/5950746406_bfcd7a45f1_b1.jpg
05:01 PM JT-Shop: i think I'll just do that and make something for the bucket to sit on...
05:02 PM XXCoder: JT-Shop: yeah unless you loop it back and keep water moving
05:02 PM XXCoder: moving water is MUCH harder to freeze
05:02 PM XXCoder: expecially if isulated also
05:02 PM Jymmm: chicken water?
05:02 PM XXCoder: it should really only take a tiny pump
05:03 PM phipli: can you stick some salt in it?
05:03 PM phipli: what did you say it was for?
05:04 PM XXCoder: chicken drinking I think
05:05 PM Jymmm: Eh, swamp cooler float valve =)
05:05 PM phipli: JT-Shop: doesn't take much heating
05:06 PM XXCoder: I remember one guy using house water to keep driveway clear using buried pipes
05:06 PM XXCoder: he didnt heat water
05:06 PM Jymmm: JT-Shop: winterizing the chickens huh? lol
05:06 PM phipli: 4.184J per degree C
05:06 PM phipli: actually, put the water tank in the coop
05:06 PM phipli: chickens will produce ~ 10W of heat
05:06 PM phipli: each
05:06 PM phipli: more than enough
05:06 PM XXCoder: actually I think he did heat water but barely past lukewarm
05:07 PM phipli: chicken body temp is 107F
05:07 PM phipli: higher than humans
05:07 PM phipli: Cats produce 9W heat
05:08 PM phipli: so chickens, with their high body temp probably produce more
05:08 PM XXCoder: fucking pintest fucking with search results
05:08 PM JT-Shop: I never click on that place
05:09 PM XXCoder: me eitehr but google sure loves that site
05:09 PM XXCoder: aha! https://hackaday.com/2016/01/24/dont-shovel-snow-build-an-epic-melt-system/
05:09 PM phipli: this is how you clear snow : http://pop.h-cdn.co/assets/16/03/640x374/gallery-1453314383-this-one-works.jpg
05:10 PM XXCoder: lol yeah. russia snow wins.. usually
05:10 PM phipli: tried that in the UK too
05:11 PM phipli: this is in the UK : https://pbs.twimg.com/media/Bz1gdknIQAA2BdG.png
05:12 PM JT-Shop: XXCoder: add this to your search string -pinterest
05:12 PM phipli: http://www.alangeorge.co.uk/Images_D-H/DowlaisTop_Winter1947_JetEngineSnowplough.jpg
05:12 PM phipli: JT-Shop: good idea
05:12 PM XXCoder: you're talking to guy that has IT and CS degrees ;)
05:12 PM phipli: probably worth making a search script
05:12 PM XXCoder: dont teach grandmother to suck egg LOL
05:13 PM phipli: XXCoder: better to give un-needed helpful hints than miss a chance to teach someone something they find useful
05:13 PM XXCoder: oh I know, was teasing our friend jt here :)
05:14 PM XXCoder: when website doesnt have boolean search system I get pissed :(
05:15 PM phipli: I'm ok at computers, but poor at internet things
05:15 PM phipli: I should have learnt website stuff (html / css)
05:15 PM phipli: but never did
05:16 PM XXCoder: me either, I thought I'd get programming job but web stuff demend shot up so much
05:16 PM XXCoder: and cs isn't too friendly to disabled people on hiring sadly though not as bad as some other areas of employment.
05:16 PM XXCoder: fast food is one of worse
05:16 PM phipli: what sort of thing is your bread and butter?
05:17 PM XXCoder: C :) I love that language funny thing.
05:17 PM XXCoder: been not programming for so long that I probably need some hours to review and recall
05:17 PM XXCoder: someday it'll be like COBOL, few programmers, insane demend
05:17 PM renesis: no way
05:18 PM phipli: my missus worked on the other side of the fence to a client who was head of IT at a company, and paralysed
05:18 PM renesis: embedded is becoming more and more commkon
05:18 PM phipli: even needed help breathing
05:18 PM renesis: most embedded is c
05:18 PM phipli: respect to his work for making the effort
05:18 PM phipli: kept him on
05:18 PM XXCoder: phipli: nice!
05:18 PM phipli: after things happened
05:19 PM XXCoder: renesis: yeah, though I never could find any job. I really suck on interviewing and remembering proper terms, so that does not help at all
05:19 PM phipli: has "two rare conditions called Transverse Myelitis & Guillain Barre Syndrome"
05:19 PM XXCoder: I have machinist job now because I went to job training place, and proved I could do it, then I got current job
05:20 PM phipli: awesome
05:20 PM phipli: gcode is an interesting language
05:20 PM phipli: quite old school
05:21 PM XXCoder: yeah
05:21 PM XXCoder: it reminds me of asm a little
05:22 PM XXCoder: I loved asm assignments at college LOL
05:22 PM Phiplii: half asm, half scripting language
05:22 PM XXCoder: most students used bubble sort to do in C then asm
05:22 PM XXCoder: I picked quite a bit harder merge sort
05:22 PM Phiplii: I like how the simplicity of asm causes the complexity
05:23 PM XXCoder: esentain liked simple equations that cause complexity than complex equation to do simple thing
05:25 PM Phiplii: ever played tis-100
05:25 PM Phiplii: awesome computer game
05:25 PM Phiplii: kindof
05:25 PM XXCoder: looking
05:26 PM Phiplii: the premise is reverse engineering an 80s computer
05:26 PM Phiplii: through assembly
05:29 PM XXCoder: interesting
05:29 PM XXCoder: not really my thing
05:29 PM Phiplii: :)
05:29 PM XXCoder: of course someone recreates it using game https://www.youtube.com/watch?v=yMnOEgbm2fE
05:30 PM Phiplii: it is basically like trying to implement a project with 512b Ram
05:31 PM XXCoder: most I did was discovery of better versions of some minecraft circuits
05:33 PM Phiplii: :)
05:42 PM Kevin`: lots of real projects fit in 512b ram
05:43 PM Phiplii: yes
05:43 PM XXCoder: there was lot of insane stuff fitting in tiny disk space.
05:43 PM Phiplii: lots of projects fit in the registers
05:43 PM Phiplii: with no ram
05:45 PM XXCoder: teris 140 bytes
05:45 PM XXCoder: https://output.jsbin.com/egiqul/49
05:45 PM XXCoder: you can fit source in tweet
05:46 PM XXCoder: function(a,b,c,d){d+=c; return[d<0|a&b<<d?a= parseInt((a|b<<c) .toString(d=32,b=new Date&2|1) .replace('v',''),d): a|b<<d,a,b,d]}
05:49 PM Jymmm: 10 LPRINT CHR$(12) 20 GOTO 10
05:49 PM XXCoder: 10 echo Jymmm
05:49 PM XXCoder: 20 goto 10
05:50 PM XXCoder: if irc worked like that you'd get so many dings
05:50 PM Jymmm: XXCoder: not as eveil as mine
05:50 PM XXCoder: hmm 12... is that ascii for bell?
05:51 PM Phiplii: cntl g...
05:51 PM Phiplii: cant remember
05:51 PM Phiplii: *ctrl
05:51 PM Phiplii: but it was ctrl g
05:51 PM JT-Shop: interesting the crop is much bigger at the end of the day
05:52 PM Phiplii: JT-Shop : yup
05:52 PM XXCoder: line feed
05:52 PM Phiplii: greedy buggers
05:53 PM XXCoder: ah ascii 7 is ring bell
05:54 PM JT-Shop: the ones that let me touch them you can feel it is like a big ball lol
05:55 PM XXCoder: https://www.theverge.com/2012/5/14/3014698/assembly-4k-demoscene-fractals 4k program
05:55 PM Phiplii: should be empty in the morning
05:55 PM JT-Shop: my buddy was into fractals back a long time ago
05:56 PM Phiplii: worth getting them used to you checking
05:56 PM JT-Shop: I'll look now that I know what to look for
05:56 PM XXCoder: is video playing music or something?
05:56 PM JT-Shop: most don't mind me putting my hand on their chest but none like to be touched on the back
05:56 PM XXCoder: because I see light pulses
05:57 PM JT-Shop: yes there is music
05:58 PM JT-Shop: and the music is part of the 4k limit I think
05:58 PM JT-Shop: the light flashes are like a tapping sound of a hammer on something solid
05:59 PM XXCoder: 64k demo https://www.youtube.com/watch?v=ZfuierUvx1A
06:07 PM Phiplii: if any of them get a compacted crop you need to massage it
06:07 PM Phiplii: which they don't like
06:09 PM JT-Shop: they don't like me to pick them up either, now only the barred rock rooster is the only one that jumps up into my lap when I sit down
06:18 PM Phiplii: treats
06:18 PM Phiplii: the more you do, the easier it is
06:20 PM JT-Shop: so far grasshoppers are a bit treat...
06:20 PM JT-Shop: time to heard the peeps into the run and watch the pot of texas red
06:21 PM JT-Shop: texas red == chili with no fillers or beans!
06:23 PM JT-Shop: XXCoder: someone is doing a remake on my 2020 stuff lol
06:24 PM JT-Shop: err a make not remake
06:28 PM Phiplii: 2020 stuff?
06:34 PM Roguish: texas red chili with chicken?
06:35 PM Phiplii: well, full size raptors are hard to find
06:36 PM phipli: http://elephantandchicken.co.uk/misc/Nonsense.jpg
07:04 PM Jymmm: wheres the elephant?
07:09 PM phipli: just out of shot
07:10 PM Jymmm: Bah, damn photographers!
07:30 PM phipli: Jymmm: just keeping what is important in frame
07:37 PM XXCoder: JT-Shop: the legs and such?
07:38 PM XXCoder: JT-Shop: my 90 degree suppoirt is added to collections and downloaded a lot but nobody ever posted any makes bleh
08:17 PM Jymmm: Phiplii: eleFUNpts are important, mkay
08:23 PM hazzy: I've been personalizing some cheap flashlights for the kids. This one came out good
08:23 PM hazzy: http://i.imgur.com/yMAsmPB.jpg
08:23 PM hazzy: except for having the engraving a little deep. Ooops, guess it is not watertight anymore...
08:23 PM XXCoder: wonderful lol
08:23 PM XXCoder: well you can always use hotglue
08:24 PM XXCoder: tape outside and make sure its nice and tight
08:24 PM XXCoder: and coat it from inside
08:24 PM XXCoder: or maybe epoxy is easier
08:25 PM hazzy: Yeah, the battery compartment is oversized so a little epoxy will make it right
08:26 PM pink_vampire: is there a safe mist coolant?
08:27 PM XXCoder: define safe?
08:28 PM pink_vampire: for indoor use, no ventilation require
08:28 PM Jymmm: water
08:28 PM hazzy: The fogbuster is good. Hardly any mist if set right so it dont realy mater what you use
08:28 PM Jymmm: water or liquid hydrogem
08:28 PM XXCoder: distalled water yeah
08:30 PM pink_vampire: distalled water will rust the machine
08:31 PM XXCoder: doh lol was thinking my machine which is alum lol
08:31 PM XXCoder: though there is water thats been deionized
08:33 PM pink_vampire: XXCoder: deionized is grate for not just rust but also pitted
08:33 PM XXCoder: hmm remembered wrong then lol
08:33 PM pink_vampire: this is why deionized water is use in edm.
08:35 PM XXCoder: what other options is there that is safe for human to breathe in but also great on cooling
08:36 PM XXCoder: old job I used wd-40
08:36 PM XXCoder: though not by mister but by hand spraying
08:37 PM SpeedEvil: XXCoder: bacon
08:37 PM SpeedEvil: (grease)
08:37 PM XXCoder: fancy
08:37 PM SpeedEvil: actually - not so much cooling for that.
08:38 PM SpeedEvil: glycerine?
08:38 PM pink_vampire: alcohol?
08:38 PM XXCoder: its not, its veg oil
08:38 PM Jymmm: FREON
08:39 PM XXCoder: Jymmm: i always wondered if AC output dense and cold air could serve as coolant for tools lol
08:39 PM SpeedEvil: http://onlinelibrary.wiley.com/doi/10.1002/jctb.5010150701/abstract
08:39 PM Jymmm: if you dont mind depleating the ozone that is
08:39 PM SpeedEvil: XXCoder: not really
08:39 PM Jymmm: XXCoder: plus condensation
08:39 PM SpeedEvil: XXCoder: AC output air is at most going to be ~30F or so, and _horribly sucky_ with regards to heat transfer
08:40 PM XXCoder: Jymmm: can always use stirling air liquidifer lol
08:40 PM SpeedEvil: Unless you actually liquify it, which has other issues.
08:40 PM XXCoder: speed hmm yeah that it does, air don't have much heat contain ability
08:40 PM XXCoder: water has so much
08:40 PM XXCoder: air, very little
08:41 PM XXCoder: sigh today is first day my room is bit hot. bleh
08:41 PM XXCoder: welcome, summer
08:41 PM pink_vampire: I got a new toy
08:42 PM hazzy: How about using a vortex tube?
08:42 PM hazzy: They produce cold air down to about -50f from compressed air and have no moving parts.
08:42 PM hazzy: commonly used for machining and can be homemade
08:42 PM pink_vampire: https://www.lowes.com/pd/Kobalt-Quiet-Tech-4-3-Gallon-Portable-125-PSI-Electric-Twin-Stack-Air-Compressor/1000125721
08:42 PM SpeedEvil: Not so much heat containing ability, (though that is about 0.1%), heat containing ability, times thermal conductivity, which takes it down to around 0.03%)
08:42 PM XXCoder: pink_vampire: what toy?
08:43 PM XXCoder: nice
08:43 PM pink_vampire: XXCoder: I sent a link
08:43 PM XXCoder: yeah saw
08:43 PM hazzy: https://www.zoro.com/exair-vortex-tube-ss-8-cfm-550-btuh-3208/i/G0387597/?gclid=CjwKEAjwm7jKBRDE2_H_t8DVxzISJACwS9Wb2s5k7hsFKlDCRFtJBvsI2BrXjO917XAGGyi9O6JCkRoC3vbw_wcB&gclsrc=aw.ds
08:43 PM SpeedEvil: Ah yes. 60dB of whisper-quietness.
08:43 PM SpeedEvil: (which admittedly is quiet for a compressor)
08:44 PM XXCoder: SpeedEvil: yah I bet liquid air would be cold enough to strunk stock and alter cutting sizes. not very good lol
08:44 PM pink_vampire: the machine is much louder
08:44 PM SpeedEvil: XXCoder: indeed. Unless you're cutting rubber
08:46 PM XXCoder: new bad obessioon motorsport!
08:47 PM hazzy: Interesting: https://arizonavortex.com/
08:49 PM pink_vampire: is there something like that that can work on 2scfm?
08:49 PM XXCoder: bah just outtakes
08:49 PM hazzy: https://arizonavortex.com/wp-content/uploads/2017/03/2017_02-fa98df6e-e32b-4649-8e6b-b1c6066a6883Cool-Tool-on-a-machine-576x1024.jpg
08:51 PM SpeedEvil: Adding even a _tiny_ amount of mist spray will enormously increase the cooling
08:52 PM Jymmm: SO PWM the mist for every couple of seconds???
08:52 PM hazzy: The Cool Tool looks like a really nice unit, but it needs 15CFM. You still have time to return your new compressor :)
08:52 PM hazzy: https://arizonavortex.com/wp-content/uploads/2017/03/avtmccooltool-pg-8.pdf
08:52 PM SpeedEvil: you'd want the mist continuous, at a low rate
08:52 PM Jymmm: ah
08:53 PM SpeedEvil: I do wonder if the above is actualy meaningful
08:53 PM SpeedEvil: compared to - for example - simply exhausting through a 5CFM orifice (which will cool the air significantly)
08:54 PM SpeedEvil: (as the 5CFM will be several times the 'cold' flow.)
08:55 PM pink_vampire: how the vortex work?
08:56 PM SpeedEvil: 70F cooler, means your part will (at the same flow) be at most 70F cooler. But if you double the flow, compared to the -70F air, that's going to have a very much larger effect unless you are actually using stuff that objects to 30-40F temp rise
08:56 PM hazzy: Like a centrifuge, colder air is denser so separates from the work air if accelerated fast enough
08:57 PM Jymmm: pink_vampire: Just turn your bedroom into a walk in freezer, problem solved ;)
08:57 PM pink_vampire: Jymmm: NO!
08:57 PM roycroft: it got up to 40 today
08:57 PM roycroft: i went to the coast to escape the heat and it was 34 there
08:58 PM roycroft: the record high for the day where i went was 18
08:59 PM roycroft: that was blown out of the water today
09:00 PM pink_vampire: all i need is to get better chip evacuation, cooling is not an issue because the slow spindle, and the slow feed rate.
09:00 PM XXCoder: air alone should work, though you can always use some mister
09:00 PM XXCoder: I remember at old work they used mister with some blue thing that is 10% to 90% water
09:00 PM roycroft: get an fine air nozzle and focus it on the part
09:01 PM pink_vampire: i want to pulse the air
09:01 PM XXCoder: *ratio of 10% chemical to 90% water)
09:01 PM Jymmm: toilet puck! lol
09:01 PM XXCoder: I remember label saying its envormentally safe but I cant remember more details. in fact I forgot this till now
09:02 PM Jymmm: XXCoder: anti-rust agent?
09:02 PM XXCoder: possibly?
09:03 PM SpeedEvil: http://www.ashburnchemical.com/evo_elements/pdf/A-609%20Ashburn%20MIST%20tds.pdf
09:03 PM SpeedEvil: for example XXCoder
09:03 PM XXCoder: interesting
09:04 PM XXCoder: well ashburn seems good
09:04 PM XXCoder: 5-10% mixture in most cases
09:04 PM XXCoder: few exception is lower than that none above
09:05 PM XXCoder: SpeedEvil: it says its blue, it may well be same one im talking about.
09:05 PM XXCoder: though not for sure
09:05 PM hazzy: "ASHBURN MIST is non-irritating to the machinist." What about to other people?
09:05 PM XXCoder: fuck non-machinists
09:05 PM SpeedEvil: That was just the first one I found when searching 'water soluble mist coolant'
09:05 PM SpeedEvil: I'm sure there are many, in various colours.
09:05 PM XXCoder: probably
09:05 PM XXCoder: lemme try
09:06 PM XXCoder: theres greencut thats also good for envorment
09:08 PM XXCoder: kool mist looks familiarn to me but its been too long
09:09 PM pink_vampire: for blowing the chips I'm using about 5 psi
09:09 PM XXCoder: well pink_vampire theres good number of options
09:20 PM enleth: TIL: the Bridgeport fits comfortably onto two pallets under 800kg each
09:21 PM enleth: just by taking off the table, head, ram and eletrical/control cabinets
09:22 PM enleth: incidentally, those are easy to remove
09:23 PM enleth: going any further would be a huge PITA
09:23 PM MacGalempsy: yo yo yo
09:23 PM XXCoder: yo
09:23 PM MacGalempsy: whats going on today?
09:23 PM enleth: well, three pallets actually, but one of them has a lot of space left for other things
09:24 PM * Tom_itx pulls on MacGalempsy's yo yo string
09:24 PM XXCoder: enleth: heard bridgeports is getting rare because stopped making em and old ones is getting worn>
09:24 PM XXCoder: ?
09:24 PM MacGalempsy: loading up and calling it quits?
09:24 PM Tom_itx: got my mill up and runnin again
09:24 PM enleth: XXCoder: it's still possible to get new spare parts for the manual ones
09:25 PM XXCoder: interesting. work has 2 bridgeports now. they used to have only one but when sister company went under we got another
09:25 PM MacGalempsy: Tom_itx even though i spent a lot of time in california, that is a little too personal
09:25 PM enleth: XXCoder: not so good for dedicated CNC models, but mine is in a pretty good condition and under very light use now, so I expect it to last a long time
09:26 PM MacGalempsy: curious if anyone in here turns their own custom darts?
09:26 PM enleth: XXCoder: unless someone actually manages to crack a major casting, I don't expect it to fail at all
09:26 PM XXCoder: yeah they are well made eh en
09:27 PM enleth: XXCoder: AFAIK the only serious problem that could lead to a cracking in a properly used and maintained bridgeport is a stuck knee gib
09:27 PM MacGalempsy: gregcnc, u around?
09:27 PM MacGalempsy: nope
09:29 PM enleth: XXCoder: still, there is a long, detailed thread on Practical Machinist forums by Forrest Addy, detailing the proper knee gib removal procedure in case it gets stuck. Doing it any other way could easily crack the knee dovetails
09:30 PM * XXCoder is glad he doesnt do machines maintance at work
09:30 PM XXCoder: seriously some of machines there is hellish to keep in good repair, like office mill
09:30 PM enleth: I guess any damage to the quill would also be a major problem
09:30 PM XXCoder: its tool changer got to run roughly again, and guy who does maintance said "just keep running, fuck it"
09:30 PM enleth: everything else can be replaced
09:31 PM enleth: OTOH, you could just fit a completely new/different head to the ram and keep going
09:31 PM enleth: getting a full bridgeport clone head cheap is easy
09:31 PM XXCoder: if you have other machines means more repairing options too I gyuess
09:31 PM XXCoder: brb
09:32 PM roycroft: bridgeport heads are cheap and plentiful
09:32 PM enleth: obviously all that makes little sense if you're running a real business
09:32 PM roycroft: so quill damage isn't as big a deal as one might think
09:32 PM enleth: but if you're running a real business, a bridgeport is not your primary workhorse anyway, I suppose
09:32 PM roycroft: if your business is prototyping it might be
09:32 PM enleth: roycroft: I think the quills are fitted to specific head castings at the factory, so they're not swappable
09:33 PM roycroft: could be, but if a whole head is easy to find and swap out then that's doable
09:33 PM enleth: again, it's a bit worse for the CNC models
09:33 PM enleth: completely different head
09:33 PM enleth: I think a manual-style head would fit, though
09:34 PM enleth: the bolt pattern should be the same, the alignment boss might not be
09:35 PM enleth: but the original CNC head for a rigid ram model is a much more massive casting than the classic manual version
09:35 PM XXCoder: sorry back
09:36 PM enleth: weighs a lot more, for sure, even without the servo
09:38 PM enleth: I expect the Z axis ball screw to be impossible to get as a spare part and a massive PITA to manufacture, so that's probably the single most important part to keep in good condition and protect from damage
09:39 PM enleth: it's almost as thick as the quill itself and hollow so that the spindle cartridge can pass through it
09:40 PM enleth: I don't even want to know how much would it cost to make a one-off replacement
09:41 PM Mac-Phone is now known as MacGalempsy
09:41 PM XXCoder: even in-shop I bet
09:41 PM enleth: if you can do it at all
09:42 PM enleth: aren't those ground after machining and heat treatment?
09:42 PM enleth: they look plated, too
09:42 PM enleth: not sure if that's chrome or what, but I think there is some kind of plating on them
09:43 PM XXCoder: ballscrews, the best quality ones, are ground
09:43 PM XXCoder: but it can be milled on lathe for less but still decent quality
09:43 PM enleth: if you can do all that in-shop, there's very little you can't fix
09:45 PM XXCoder: I bet
09:48 PM enleth: anyway, I expect this mill to keep working as long as I have it, other than maybe electrical problems
09:49 PM roycroft: i need to boil some prawns but i don't want to turn the stove on in this heat
09:49 PM roycroft: i'm considering using my brew system burner to do it :)
09:49 PM enleth: light and infrequent use, small jobs, mostly educational/training use and some prototyping
09:49 PM enleth: it's doing close to nothing really
09:49 PM roycroft: i just don't know if it will focus the heat on an area as small as the pot i'm using
09:50 PM * roycroft will just scrounge up something that requires no cooking
10:03 PM MacGalempsy: XXCoder: how is the router working out?
10:04 PM XXCoder: great if i was actually working on it
10:04 PM XXCoder: sadly im not lol
10:25 PM MacGalempsy: XXCoder: what have you made, so far?
10:49 PM XXCoder: not much lol
10:49 PM XXCoder: been too down to work on it
11:36 PM MacGalempsy: that socks
11:37 PM MacGalempsy: *sucks
11:37 PM XXCoder: yeah
11:37 PM MacGalempsy: in a few weeks, I should be off for a few weeks. I'll be back to work on getting the ATC up and going.
11:37 PM pink_vampire: http://i.imgur.com/ELbsQSm.png
11:38 PM MacGalempsy: blue = dyekem
11:38 PM MacGalempsy: :p
11:38 PM XXCoder: unless so royal blood is luterally blue lol
11:39 PM MacGalempsy: heh
11:39 PM pink_vampire: MacGalempsy: https://www.zoro.com/dykem-layout-fluid-steel-redtm-4-oz-80396/i/G0599182/?gclid=CNPMm-WP2NQCFY-Eswodc1MCxA&gclsrc=aw.ds
11:39 PM XXCoder: ah red version. forgot
11:39 PM MacGalempsy: i know, but red dyekem is too confusing w blood, so who uses it?
11:40 PM pink_vampire: i don't know'
11:40 PM MacGalempsy: so p.v. what have you been making?
11:41 PM pink_vampire: I'm using the super large black sharpie
11:41 PM MacGalempsy: sharpie washes off w oil
11:42 PM pink_vampire: I didn't do much today, but yesterday i did the t-slot nuts
11:42 PM pink_vampire: my machine is oil free
11:43 PM pink_vampire: MacGalempsy:
11:44 PM MacGalempsy: cool. whats the project?
11:45 PM MacGalempsy: for the nuts
11:45 PM pink_vampire: http://i.imgur.com/TFDVtCo.png http://i.imgur.com/sPqfEFq.png http://i.imgur.com/AYSTUo7.png
11:46 PM MacGalempsy: que es eso
11:46 PM pink_vampire: ??????????
11:46 PM MacGalempsy: what is that?
11:47 PM MacGalempsy: spindle mount?
11:47 PM pink_vampire: tool setter
11:47 PM MacGalempsy: claro
11:48 PM pink_vampire: ????
11:48 PM MacGalempsy: i see ;)
11:48 PM MacGalempsy: hahah, ive been cramming on spanish lately.
11:48 PM pink_vampire: did you saw that? http://i.imgur.com/cbGNhB6.png
11:49 PM MacGalempsy: haha. looks like a boob
11:49 PM pink_vampire: it is a boob
11:49 PM MacGalempsy: yours?
11:50 PM pink_vampire: it was a gift / joke for my friend
11:50 PM MacGalempsy: a monopoly game piece
11:51 PM pink_vampire: no..
11:52 PM MacGalempsy: i meant it could be
11:53 PM pink_vampire: now i'm working on the toolpaths for the base plate
11:53 PM MacGalempsy: so rhenium darts are what I need
11:54 PM MacGalempsy: that sounds neet. im working on drilling at 35ft/hr
11:55 PM pink_vampire: 35ft/hr??? mm/min.. ipm..
11:55 PM pink_vampire: 177.8mm/min
11:55 PM pink_vampire: that is relatively fast
11:56 PM pink_vampire: I like 25 to 5 mm/min
11:56 PM MacGalempsy: like 4ipm
11:56 PM MacGalempsy: my hole dia. is 8 3/4"
11:57 PM pink_vampire: 8 inch drill O_o
11:57 PM MacGalempsy: depth is like 12000ft
11:57 PM pink_vampire: are you drilling oil?
11:58 PM MacGalempsy: https://flic.kr/p/T565Ts
11:59 PM MacGalempsy: yeah
11:59 PM pink_vampire: suuuper cool!
