03:32 AM Deejay: moin
03:38 AM XXCoder: interesting project https://imgur.com/a/zTHLmCm
03:38 AM XXCoder: hey Deejay gloops
03:39 AM gloops: hi
03:39 AM Deejay: hey
03:40 AM gloops: looking at cutters, finding some limitations for the scroll saw pattern for the bee i bought
03:41 AM gloops: 2mm endmill only comes in 15mm length, so cant make it deeper than that
03:42 AM XXCoder: unless you order custom heh $$$
03:43 AM XXCoder: work uses very few custom tools, one of em were a very long tapping tool for diameter
03:43 AM gloops: yeah i wouldnt go with expensive stuff, not for something im likely to break a lot of lol
03:43 AM gloops: 15mm is okish, 20 would have been better
03:44 AM gloops: just shows she is pretty good with the scroll saw hers are 3/4 inch
04:01 AM russian_troll: selroc: Today's Log http://www.isaeff.net/logs/%23linuxcnc/2019-01-07.html
04:26 AM PL7icnc: good day
04:27 AM PL7icnc: Loetmichel_, Are You Here
04:28 AM -!- #linuxcnc mode set to +v by ChanServ
04:32 AM PL7icnc: somone here from Mesanet
04:33 AM PL7icnc: pcw_home,
04:33 AM PL7icnc: pcw_mesa, Are You Online
04:35 AM rmu: hmm
04:35 AM rmu: PL7icnc: you don't need permission to ask questions
04:37 AM PL7icnc: is there a Sign on the 7i76e Showing Source or Sinking as the Images in Store are the same
04:38 AM PL7icnc: 5i25/7i76 can i mesurer if the ports Out are OK seams as EMV has killed a complete outBank
04:42 AM rmu: i guess the difference is just the output driver chip(s)
04:45 AM rmu: in any case the sinking version should be marked 7I76ED
04:46 AM PL7icnc: the images in the mesastore shoudt indicate that
04:47 AM PL7icnc: or can i change the firmware to get a sinking out of a sourcing
04:49 AM rmu: don't think so. if that was possible the store would only list one variant.
04:49 AM PL7icnc: im off Bye
05:04 AM jthornton: morning
05:06 AM Wolf__: morning jt
05:06 AM XXCoder: hey
05:08 AM Wolf__: jthornton, I think I found a mistake on the instruction sheet that was with the 7i96, ip address
05:09 AM jthornton: that looks like a typo to me
05:10 AM jthornton: the first line on that page is Ethernet Cards require LinuxCNC Uspace and the PREEMPT kernel.
05:12 AM Wolf__: yeah
05:12 AM jthornton: it can be 10.10.10.anything but 10
05:12 AM jthornton: the 7i96 is
05:12 AM jthornton: 1 should work
05:12 AM Wolf__: ahh
05:13 AM jthornton: and while I'm looking at that page I'll setup this PC lol
05:13 AM Wolf__: I think I’m going to need to rebuild my mint box lol
05:13 AM jthornton: did you use the configuration tool to build your configuration?
05:14 AM Wolf__: wont connect, I cant get hostmot2 to install/load
05:15 AM jthornton: did you install debian 9 uspace?
05:15 AM jthornton: I'm working on some new instructions for building uspace and kernels http://gnipsel.com/linuxcnc/uspace/
05:16 AM Wolf__: box I have set up right now is Mint 18 iirc
05:17 AM Wolf__: but I set it up over a year ago so used old directions w/ no clue what I was doing lol
05:23 AM Tom_L: morning
05:24 AM jthornton: morning
05:25 AM jthornton: geez 52°F with a high of 65°F today in January that's nuts
05:26 AM Tom_L: 56F, Hi 59, Lo 37
05:26 AM Wolf__: does the mint desktop version make any difference?
05:27 AM Tom_L: had a speck of rain last night
05:27 AM Tom_L: Wolf_ITX_, no
05:27 AM Tom_L: user choice
05:27 AM Wolf__: I didn’t think it would =)
05:31 AM Wolf__: now, seeing that I know jack about linux, you can build the kernel on a different cpu then move it to the target machine right?
05:41 AM jthornton: I guess you can, but why?
05:42 AM Wolf__: 2 core atom vs 4 core i5
05:44 AM Wolf__: I know the intel atom builds really slow
05:47 AM jthornton: ah I see, give it a try and see
05:53 AM jthornton: just looking on this pc and I used address
05:54 AM * jthornton installs linux mint 19.1 again to test the instructions
09:09 AM -!- #linuxcnc mode set to +v by ChanServ
10:35 AM Wolf__: jthornton: so, is the etc-linuxmint19 install instructions complete?
10:35 AM Wolf__: etc/emc
11:00 AM JesusAlos: Hi. does anybody know where is the axis.tcl file translations?
11:13 AM jthornton: Wolf__: etc/emc?
11:13 AM Wolf__: meant http://gnipsel.com/linuxcnc/uspace/emc-linuxmint19.html
11:13 AM Wolf__: but I’m still working through it
11:14 AM jthornton: almost, I have one detail to test before building the deb
11:21 AM Wolf__: so far seems noob friendly enough to follow
11:22 AM jthornton: that's what I shooting for
11:28 AM Wolf__: I did end up doing the install dependencies as a bash script
12:38 PM gloops: https://www.ebay.co.uk/itm/Mini-Watchmaker-Lathe/323631436208 little lathe went over 200
12:41 PM fragalot: o.O
12:41 PM fragalot: someone's going to be disappointed :P
12:45 PM gloops: must know something about it surely, 2 at least must have bid it that high
12:53 PM fragalot: maybe for parts they recognize
01:50 PM CaptHindsight: https://www.theverge.com/2019/1/6/18168793/samsungs-75-inch-microled-4k-tv-pitcure-quality-ces-2019
01:51 PM CaptHindsight: vs roll-up screens (aka window shade)
01:51 PM CaptHindsight: https://www.theverge.com/2019/1/7/18171013/lg-rollable-tv-oled-4k-tv-features-photos-video-release-ces-2019
02:15 PM gloops: ive got big TV fatigue
02:15 PM gloops: no doubt the great masses will pursue the big TV ideal to the very end though
02:16 PM CaptHindsight: will they run out of money first?
02:16 PM gloops: they already have
02:17 PM CaptHindsight: not enough
02:19 PM gloops: Ford realised that if you want workers to be able to buy things you have to pay them more wages
02:20 PM CaptHindsight: that is history
02:20 PM gloops: we're still using that premise, but have now realised that its far more lucrative to give them credit, rather than up their pay
02:49 PM elmo40: gloops, yeah. credit is the latest scheme
02:55 PM elmo40: stores do that instead of cash returns. they offer store credit.
03:01 PM CaptHindsight: banks want to give you credit so that you can get in trouble with it
03:01 PM CaptHindsight: they makes tons more money when you get behind
03:01 PM gloops: what they used to call usury
03:02 PM gloops: now promoted as 'easy payment plan'
03:02 PM mozmck: Renting money
03:02 PM mozmck: The rent isn't cheap
03:08 PM Jymmm: easy payment plan... for LIFE
03:08 PM fragalot: student loans.
03:08 PM fragalot: enough said
03:08 PM fragalot: first, you introduce the concept. then you get more people to join. then you more than quadruple the tuition fee
03:21 PM gloops: then you start making the as yet unborn children guarantors for the loan
03:27 PM gloops: anyone used very sharp angle V cutters on wood - like 10/20 degree angle?
03:28 PM SpeedEvil: The cutting speed gets very low at the bottom unfortunately
03:28 PM gloops: https://www.ebay.co.uk/itm/10X-10-degree-0-1mm-engraving-drill-bit-CNC-router-tool-V-shaped-alloy-PCB-board/352505289911?
03:28 PM gloops: that type
03:28 PM gloops: good point SpeedEvil
03:29 PM gloops: wondering how sturdy they are - or fragile
03:29 PM SpeedEvil: I wonder if those are in fact meant for enlarging holes.
03:29 PM The_Ball: pcb milling?
03:30 PM gloops: The_Ball i want to pick out some fine detail on wood carving, depth a couple of mm say
03:31 PM The_Ball: right, I use them for PCB milling and the finer the tip the better, but when it is that thin it takes nothing to break the tip and the cut become quite a bit wider
03:31 PM SpeedEvil: What sort of wood? You may need really fine finishes in order to not look bad. And variation over the grain direction is probably going to be big
03:32 PM gloops: what kind of depth of cut and feed for PCB?
03:32 PM SpeedEvil: Part of the thing about coarser tips is you can employ a more complex geometry.
03:32 PM SpeedEvil: So not to actually have that cutter speed=0 at the ti
03:32 PM SpeedEvil: p
03:32 PM gloops: SpeedEvil probably various woods
03:33 PM gloops: hmm, so actually a bigger tip to start is better for my purpose
03:33 PM SpeedEvil: I assume you can't do 5-axis things?
03:33 PM gloops: .3 mm be ok for me
03:33 PM gloops: nah just 3 axis
03:34 PM SpeedEvil: What's max spindle speed?
03:34 PM gloops: 24k
03:35 PM gloops: like the body hair detail on that https://www.fionakingdon.com/shop/honey-bee-hand-cut-elm-55
03:35 PM SpeedEvil: 300 revs per second, or 300mm/s cutter speed.
03:35 PM SpeedEvil: unless I'm confused
03:35 PM CaptHindsight: gloops: fetal credit, only surpassed by embryonic credit and later generational credit futures
03:36 PM The_Ball: been cleaning up the wiring on my old mill https://imgur.com/a/7BkhwGG
03:36 PM CaptHindsight: you can take out loans on the great great grand kids before they are even born
03:36 PM gloops: it works, but there will be a crash when immortality is discovered
03:37 PM CaptHindsight: nah, they will just pass laws on the poor not being able to go over 100
03:37 PM The_Ball: this is what it looked like when i bought it: https://imgur.com/a/QlVDHbQ
03:37 PM CaptHindsight: have to pay to play
03:38 PM gloops: hope you didnt pull any wires out The_Ball lol
03:39 PM The_Ball: hehe, well I did but it wasn't working, now it is working and converted to LinuxCNC/Mesa
03:40 PM gloops: SpeedEvil i guess ill have to check out some PCB figures and watch some videos - these cutters are only pennies each anyway i may as well get some and play..until theyre gone
03:40 PM The_Ball: It has a DC spindle drive which was a pain to fix
03:42 PM SpeedEvil: gloops: not a wholly bad plan
03:42 PM gloops: is this for commercial use The_Ball, i mean is this your business or something?
03:43 PM The_Ball: No, just hobby
03:45 PM gloops: well theres hours of fun to be had with a mill like that heh
03:55 PM CaptHindsight: The_Ball: have a pic of the whole machine? (did i miss the link?)
03:56 PM CaptHindsight: i enjoy building them more than running them
03:56 PM CaptHindsight: designing really, even assembly can get boring
03:58 PM The_Ball: CaptHindsight, the front https://imgur.com/a/SGPOM8R
03:59 PM CaptHindsight: looks familiar, what was it?
04:00 PM The_Ball: It's an old swedish brand, "Modig" MD-5000
04:00 PM The_Ball: Built around 1985 I think
04:00 PM syyl: the arm that holds the controll panel looks more rigid than a lot of hobby mills ;)
04:01 PM CaptHindsight: andypugh: hi, was just wondering about what Ford is using for e-car motors
04:01 PM The_Ball: The control panel has a touch screen and running gmoccapy. Still want to break out a few selectors to the panel though
04:06 PM Deejay: gn8
04:17 PM * fragalot wishes ST would pull their head out of their ass & release libraries that ACTUALLY work
04:17 PM fragalot: so many example files for specific CPU's that are just plain wrong
04:18 PM renesis: like what?
04:18 PM fragalot: linker files saying the F303K8 has 16K of stack space whilst it's only really got 12
04:18 PM renesis: all the cubemx and std periph shit ive tried worked
04:18 PM fragalot: so the second you hit "run" it just hardfaults instantly
04:18 PM renesis: that sucks
04:19 PM fragalot: for the 722ZE the unique ID was wrong in the datasheet
04:19 PM renesis: what library are you using?
04:19 PM fragalot: for the 496ZG (iirc, could be a different one), ST-Link tools can not enable the OTP bits
04:19 PM Rab: The_Ball, nice machine. Looks like one of the drives is missing in the second pic, was it dead?
04:19 PM fragalot: etc
04:19 PM fragalot: renesis: bit of everything. Depends on what I need and which lib does it best.
04:20 PM fragalot: CMSIS, STM32Hal, ChibiOS HAL, ...
04:20 PM renesis: ah, i figure theyve given up on everything except the cubemx HAL stuff
04:20 PM fragalot: and Atollic as the debug env. because that just works.
04:20 PM renesis: yeah i went from keil to atollic, only thing i changed was byte alignment syntax
04:20 PM fragalot: i'm using cubeMX to generate my board config once & use python scripts to export it to the right format I need
04:21 PM renesis: haha hacker
04:21 PM fragalot: the UI makes it fairly nice, but the code it generates is annoyingly inconsistent :P
04:21 PM fragalot: and I like my hardware configuration to not change behind my back :D
04:22 PM renesis: i generate with cubemx and basically insert two or three functions and couple of includes into it, so easy to fix if it clobbers code
04:22 PM renesis: working well so far
04:22 PM fragalot: that's another way of doing it
04:22 PM renesis: can tweak in cubemx and update, and lately it hasnt had issues
04:22 PM fragalot: i'm using that python script so it generates code that ChibiOS likes
04:23 PM fragalot: well, I go from cubeMX --> intermediate config file for ChibiOS --> board.c & board.h file
04:24 PM fragalot: board.chcfg is what chibiOS uses as the format
04:24 PM renesis: havent played with any rtos on stm32 yet
04:24 PM The_Ball: Rab, the missing drive was for a forth axis, which I haven't got, so have removed it while debugging the spindle drive
04:25 PM renesis: nom, toolchanger
04:40 PM Jymmm: rene_dev_: Pfff, now THIS is a tool changer (aka cnc porn)... https://www.youtube.com/watch?v=9MFRPGf4JDk
04:40 PM Jymmm: renesis: ^^^^^^^^^^^^^^
04:47 PM renesis: ha
04:47 PM Jymmm: renesis: More cnc porn https://www.youtube.com/watch?v=FqPA8DM-43k
04:48 PM renesis: the ones where they grab a tool from some carousel outside the machine are pretty nuts
04:48 PM renesis: changer bigger than the machine
04:48 PM Jymmm: heh
04:49 PM Jymmm: haha, I just read the first comment on that last video
04:50 PM Jymmm: the live handoff is orgasmic =)
05:02 PM gloops: hmm, they are ok, you really need the tool rack under the work surface though, with a metal iris to open when the tool needs changing
05:11 PM The_Ball: lol, that IS a toolchanger, but I'm very very happy to have my first toolchanger even if it only 15 pockets
05:15 PM SpeedEvil: gloops: With a rotating ring around the iris and blue LASER illuminating a fine coolant mist?
05:23 PM Jymmm: Not bad at all actually... https://www.youtube.com/watch?v=d-BWmPaBfjQ
06:29 PM Sabotend_ is now known as Sabotender
06:32 PM Wolf__: jthornton: around? ran “./configure --enable-build-documentation” and get a “configure: error: intltool-extract not found”
06:40 PM ziper: how much is this worth
06:40 PM ziper: https://www.bidspotter.com/en-us/auction-catalogues/bscsta/catalogue-id-bscsta10021/lot-49d35b31-b866-4d25-956c-a9c300d6f9af
06:40 PM ziper: I thought you could dress a wheel with just a little hand tool
06:41 PM Wolf__: for surface grinder
06:41 PM Wolf__: to do angles/radius dress
06:43 PM ziper: oh
06:43 PM ziper: neat
06:46 PM Wolf__: checking to see what I paid for mine
06:47 PM Wolf__: https://i.imgur.com/oZi6h4Z.jpg $105 for the lot
06:52 PM ziper: wow looks identical
06:56 PM ziper: anybody used an optical comparator?
07:01 PM Jymmm: not i a bazillion years
07:02 PM ziper: what made them obsolete?
07:03 PM Jymmm: Not digital enough? lol, I don't have a clue =)
07:04 PM andypugh: CaptHindsight: I don’t know. Something off the shelf. Ford seem to be watching the market at the moment, seeing which way it goes. Try buying an electric Ford...
07:07 PM ziper: this IS a horizontal machine, right? https://www.bidspotter.com/en-us/auction-catalogues/bscsta/catalogue-id-bscsta10021/lot-3f528660-cd9b-4503-8df6-a9c300d6f9b3
07:07 PM andypugh: If you can find one, the pantograph dressers can make impossibe jobs easy. Search this page for “Diaform” http://www.lathes.co.uk/jonesandshipman/page5.html
07:08 PM andypugh: ziper: Cute mill. Do you need a museum piece :-)
07:08 PM ziper: whats wrong with it?
07:08 PM CaptHindsight: https://www.ford.com/new-hybrids-evs/
07:09 PM andypugh: It’s lovely, if you want a collection of old machine tools.
07:09 PM CaptHindsight: US anyway
07:09 PM andypugh: CaptHindsight: Aye, but low-mix hybrids
07:10 PM ziper: i'm not getting a 20k cnc anytime soon
07:10 PM andypugh: (not that the others are much better, my sister has a hybrid Golf with 4 miles electric range at < 30mph
07:10 PM ziper: but if I need a specific gear, it would be nice to have
07:11 PM andypugh: I have a horzontal mill myself, but it has a vertical head, and is from the 60s not the 30s.
07:11 PM ziper: would a nichols be better?
07:12 PM andypugh: https://www.youtube.com/watch?v=86MN3CN7Aiw A reare example of CNC horizontal milling (my machine)
07:13 PM ziper: I was impressed at just using a mechanically linked indexing head to make helical gears
07:14 PM andypugh: Mechanically linked is just so 20th Century :-)
07:15 PM andypugh: My Harrison is great for making custom gears, or custom timing belt pulleys
07:16 PM andypugh: https://www.youtube.com/watch?v=PFTHY5U8v-U
07:17 PM andypugh: I am not saying “don’t get a horizontal” I am saying “get one with a verical head and a lot of metal in the over-arm.
07:17 PM ziper: would such a custom profiled surface grinding wheel have an accuracy advantage over a CNC milled part?
07:17 PM andypugh: Definitely a finish advantage, and it could be made to size from pre-hardened steel.
07:18 PM ziper: what do you mean by vertical head?
07:18 PM norias: oh, surface grinding. :)
07:18 PM andypugh: ziper: It’s like a head, but vertical :-)
07:18 PM ziper: so isn't that just a vertical mill?
07:19 PM andypugh: https://www.youtube.com/watch?v=XZHsDMJKJuk and look at the 15 seconds mark. That is the vertical spindle dangling from the crane.
07:20 PM andypugh: And here it is mounted showing off the pneumatic drawbar I made.
07:20 PM andypugh: https://www.youtube.com/watch?v=pxrzJ_KfcQ0&t=21s
07:23 PM ziper: well there is two bridgeports and a clausing lathe too
07:23 PM ziper: i'll be going for whatevers a good deal
07:24 PM ziper: that drawbar is rather erotic
07:28 PM andypugh: The Clausing lathe looks OK, and new enough to have decent spindle speeds.
07:28 PM andypugh: (Though it wouldn’t hurt to do some research)
07:29 PM andypugh: You don’t have to go back too far in time to find good 12” lathes with a 400rpm top speed.
07:29 PM andypugh: (which is rather slow for modern tools and materials)
07:33 PM andypugh: And.. Sleep
11:14 PM Roguish_ is now known as Roguish
