12:00 AM Crom: hmmm steppers are now checked into Bloomington, CA
12:02 AM {HD}: DrippityDrops: I see people mention 'dithering' and 'full screen redraws'
12:02 AM Crom: amazing 13 hours to go 7000 feet
12:04 AM {HD}: ha
12:07 AM Crom: last night it was 8pm to 9am to go 9 miles
12:08 AM Crom: meaning the trailer left the yard at 8pm and unloaded the next morning
12:09 AM Crom: sorted into a new trailer, that sat until it was dark and then taken to the ground hub to be loaded into either a trailer or a truck for delivery
12:11 AM {HD}: 8600gts*
12:11 AM {HD}: Is linuxCNC 64bit?
12:11 AM CaptHindsight: {HD}: did you see this card discussed on the forums?
12:11 AM Crom: nope.. trailer to murietta
12:12 AM {HD}: Crom: Crap. What now? Which card?
12:12 AM Crom: {HD}: can be... I'm running it on a 64bit machine, kernel and libc
12:12 AM {HD}: whoops
12:12 AM {HD}: CaptHindsight: Crap. What now? Which card?
12:12 AM {HD}: Crom: I mean the .iso you can pull from linuxcnc
12:12 AM justan0theruser is now known as justanotheruser
12:15 AM Crom: no, you have to build it
12:15 AM Crom: hmmm on second thought... lemme double check
12:16 AM Crom: CaptHindsight: did you try loading modprobe parport_pc io=0xd000 for the moschip?
12:16 AM Crom: also io=0xe000 0xc000 ...
12:20 AM {HD}: Crom: So you went Wheezy with Preempt-RT kernel?
12:20 AM {HD}: I am installing on a 64bit machine but, would I see any benifit to using a 64 bit OS for just machine control?
12:20 AM Crom: {HD}: nope... I went Debian-8.7-amd64 from debian (Jessie) kernel 4.9.13-amd64-rt12 from kernel.org and 2.8.0-pre1 linuxcnc from linuxcnc somewhere
12:20 AM Crom: and compiled it
12:21 AM Crom: CaptHindsight: true..
12:22 AM Crom: hmmm wonder if it's time to add a port check into parport for the 0x?000 ports
12:22 AM CaptHindsight: crom CH382L impostor cards
12:22 AM MacGalempsy: linux mint is so much easier to use than the standard dist
12:22 AM Crom: mint is just another debian flavor
12:23 AM {HD}: MacGalempsy: Yea, I run mint and like it. Just not for CNC.
12:23 AM Crom: not much that much easier
12:23 AM {HD}: Mint is a more user friendly version
12:23 AM MacGalempsy: i put it on my dual monitor laptop and its dojng pretty good
12:23 AM {HD}: MacGalempsy: So you have Mint with linuxcnc on top?
12:24 AM Crom: hmmm.... I could run dual headed on this lappy...
12:24 AM MacGalempsy: just ordered a new wifi card with bluetooth so cant wait to get rid of a few wires
12:24 AM Crom: where could I put the other screen
12:24 AM CaptHindsight: Crom: the impostors use a made up device and vendor ID
12:24 AM MacGalempsy: yea mint and linux cnc
12:25 AM {HD}: MacGalempsy: That might be what I do after I make sure my HW works with the 'easy linuxcnc.iso'
12:25 AM MacGalempsy: it takes a while to build, but you could buy a precompiled ssd from JT
12:25 AM Crom: i have a Comfast CF-WU725B I can't get going.. wifi + BT
12:25 AM {HD}: MacGalempsy: what version mint?
12:25 AM MacGalempsy: do the easy and then the latency test. if its good then go for it
12:26 AM MacGalempsy: i think its 17
12:26 AM MacGalempsy: but i hear some have had success with 18
12:26 AM {HD}: MacGalempsy: Yep, gotta wait for new parallel port card first...
12:27 AM {HD}: Really I might not take the time to go Mint on CNC because CNC is all I use it for. Dedicated machine so, it doesnt really matter.
12:28 AM {HD}: And I am running Debian host OS on my virtman machine.
12:28 AM {HD}: So, I am used to it.
12:29 AM MacGalempsy: my terminal capabilities are so limited that mint helped move things along
12:31 AM {HD}: Well, Thanks people for the help tonight...Im out!
12:32 AM pcw_mesa_ is now known as pcw_mesa
12:33 AM CaptHindsight: pcw_mesa: now I know why you asked about the CH382l cards a few months back
12:34 AM CaptHindsight: there are bootleg cards with different (made up) PCI ID's
12:35 AM CaptHindsight: good EPP cards are getting even harder to find now
12:53 AM Crom: JJ-02011-S1 SIIG cards are like$65 now at newegg
12:53 AM Crom: wish I had the money to grab that $10.95 one
12:55 AM Crom: then there is the SIIG JJ-E01011-S1 on ebay for $4.99... wonder if those are genuine or bogus
12:55 AM Crom: JJ-E02011-S1 at newegg is the 2 port card, the E01011 is a single port
12:56 AM Crom: if you're good with SMD you could get 2 E01011's and turn one into a 2port E02011
12:59 AM Crom: one is green one is tan... are they both real or is one fake? http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR0.TRC0.H0.XJJ-E01011-S1.TRS0&_nkw=JJ-E01011-S1&_sacat=0
01:23 AM Crom: hmmm 1500rpm is 20us per 1/2wave. 40us for high+low pulse hmmm that's 640 clock cycles on a 16Mhz arduino
01:24 AM Crom: hmmm on a mks 80mhz or 100mhzboard that's 3200 or 4000 clocks...
01:49 AM IchGucksLive: Morning
01:49 AM IchGucksLive: germany awakes into a very nice Weekend
01:51 AM IchGucksLive: have a nice nonBitbreaking DAY
02:05 AM Deejay: moin
02:07 AM MacGalempsy: yo
04:13 AM MacGalempsy: well, we had to slide and now we are 11hrs to td...
04:14 AM MacGalempsy: 37.8fph...i hope the bit doesn't go out
05:49 AM XXCoder: heya
05:49 AM XXCoder: I just got this flip down clamps
05:49 AM XXCoder: pretty cool
05:50 AM XXCoder: I used em at last job, they are impressively strong, good for basic stuff
05:52 AM XXCoder: hey MacGalempsy you're back
05:56 AM enleth: I remember there are a couple guys here doing CO2 laser cutting
05:56 AM enleth: do you have any idea if it's OK to use a power supply rated for a high power tube with a much smaller one?
05:57 AM enleth: mind you, the question only sounds stupid if you haven't seen the spec sheets
06:00 AM enleth: thing is, higher power supplies can handle longer tubes that require a higher excitation voltage, and usually have more than one HV transformer, connected in series - although it does look like those individual transformers are lower voltage than a single one used in a smaller supply, so that the series arrangement still arrives at ~25kV or so
06:06 AM XXCoder: well hope you figure it
06:07 AM MacGalempsy: kind of :)
06:07 AM XXCoder: https://www.youtube.com/watch?v=MGHqt_qY6XM nice
06:07 AM XXCoder: he also has nice idea, fixed XY location
06:09 AM MacGalempsy: how is your dust maker coming along?
06:10 AM XXCoder: sadly I got tons of stuff but not the very thing I wanted to start working on project on.
06:12 AM XXCoder: I'm not too sure what to do this weekend.
06:13 AM XXCoder: maybe I will try make inlay or something. I did get V bits
06:13 AM XXCoder: the 10 degree V cutter is pretty scary pointy LOL
06:15 AM XXCoder: hey JT-Mobile
06:15 AM JT-Mobile: morning
06:20 AM XXCoder: sadly I never got my 90 degree parts
06:20 AM XXCoder: so dunno what to do with machine for now LOL
06:20 AM JT-Mobile: the 2020 braces?
06:20 AM XXCoder: yeah
06:21 AM JT-Mobile: I wonder if the rest of the quad parts will show up while I'm gone
06:21 AM XXCoder: its law, as soon as you cant do anything with it, it arrives
06:21 AM XXCoder: oh yeah talking about arrivals
06:22 AM XXCoder: my stepper driver for 3d printer arrived
06:22 AM XXCoder: still waiting for more parts
06:22 AM JT-Mobile: http://gnipsel.com/images/tweaker-5/Tweaker-5-01.jpg
06:22 AM JT-Mobile: need my box of standoffs, the sbus receiver and a x60 plug and cord
06:23 AM XXCoder: cool
06:24 AM JT-Mobile: right now the board in the middle is too low so I need taller standoffs so the reciver fits under it
06:24 AM XXCoder: standoffs arrived for me also, but I think its too small
06:26 AM JT-Mobile: http://www.shendrones.com/tweaker-5/
06:27 AM JT-Mobile: it came with the printed camera mount out of some soft material
06:27 AM XXCoder: interesting
06:28 AM JT-Mobile: I need to print the antenna mounts for the purple tubes
06:28 AM JT-Mobile: http://www.thingiverse.com/thing:1517786
06:28 AM XXCoder: I dont know why its always flying platform heh
06:29 AM JT-Mobile: I assume pla will work but I wonder what the soft material is?
06:29 AM XXCoder: pla hmm strong but brittle
06:33 AM JT-Mobile: soft 3d filament
06:33 AM JT-Mobile: https://www.amazon.com/YOYI-Flexible-Filament-Diameter-Tolerance/dp/B01M9AXXZD/ref=sr_1_6?ie=UTF8&qid=1491562931&sr=8-6&keywords=soft+3d+filament
06:35 AM XXCoder: tol is pretty large
06:36 AM JT-Mobile: for a soft material?
06:36 AM XXCoder: hmm dunno
06:38 AM JT-Mobile: I asked the guy that made them
06:41 AM JT-Mobile: what material did you print the camera mounts with for the tweaker 5"?
06:41 AM JT-Mobile: <Glowtape> some pla/pha blend
06:42 AM JT-Mobile: he said tpu
06:42 AM XXCoder: thats its own kind of nplastic
06:46 AM JT-Mobile: https://filaments.ca/pages/temperature-guide#tpu
06:46 AM XXCoder: handy list
06:47 AM JT-Mobile: yea
06:48 AM XXCoder: no PMMA strangely
06:48 AM XXCoder: "To get the optimal temperature; start from 230C and continue to raise the temperature until the printers starts browning the print regularly, from that point, drop the temperature by a couple of degrees and your set. Make a note for follow-on prints."
06:48 AM XXCoder: browning?
06:49 AM JT-Mobile: almost burning?
06:49 AM XXCoder: maybe
06:52 AM JT-Mobile: maybe that is why I had so much problem printing pteg
06:52 AM XXCoder: yeah
06:54 AM XXCoder: I find it interesting that PLA has no glass in list of print surface
06:55 AM JT-Mobile: ABS juice lol
06:56 AM XXCoder: yeah you just squeeze abs fruits
06:56 AM XXCoder: ;)
07:29 AM JT-Mobile- is now known as JT-Mobile
09:13 AM CaptHindsight: why is extruding thermoplastics so baffling? Getting them to flow and adhere properly is all about temperature...
09:15 AM CaptHindsight: Ignoring the temperature of the thermoplastic at the area of contact with the surface it's being deposited onto is like ignoring the feeds and speeds of cutting tools
09:17 AM CaptHindsight: yes most of these printer designs have extruders and print areas out in the open at ambient temp with maybe only the bed having a raised temp
09:17 AM CaptHindsight: yes/yet
10:01 AM enleth: why are most of the crowdfunded "desktop" milling plotters about as rigid as a block of slightly dried jello?
10:01 AM enleth: same reason: most people who design them have no basic understanding of the problems involved
10:01 AM gregcnc: tha'ts all people want to buy
10:02 AM gregcnc: rigidity costs extra...pfffft
10:04 AM enleth: we've got a couple unenclosed 3D printers at the hackerspace, people make covers out of pizza boxes for them to restric air exchange with the surroundings
10:13 AM Simonious: I've got an assembly in solidworks, is it possible to 'mate' the corner of one of the parts in that assembly with the origin? When I export the file it's not at the origin. Obviously my fault for not positioning it right originally.
10:14 AM archivist: Simonious, may have to float the first part to mate it to the origin
10:16 AM Simonious: okay, I floated it, does a mate to the origin exist, is that a real thing?
10:16 AM archivist: you can mate a corner/edge/whatever
10:17 AM archivist: usually to a plane too
10:17 AM Simonious: so.. draw something at the origing to mate with
10:17 AM Simonious: oh!
10:17 AM Simonious: I can select the origin on the object tree
10:17 AM Simonious: great
10:18 AM Simonious: thank you
10:18 AM archivist: I have had to fix the occasional cock up :)
10:19 AM Simonious: I'm still early enough on my learning curve that I'm missing things and don't even know it, I'll go back to look at my models later and wonder what I was thinking. Went through the same thing with Sketchup, still find things that I made, that were clearly made by someone who could barely think.
10:19 AM Wolf_: if you want to look at how some pro stuff is assembled in SW you can download parts on Mcmaster
10:20 AM archivist: once you are used to it, you realise 2d drafting is silly
10:20 AM Simonious: Solidworks frustrates the heck out of me. I'm used to being able to reference any part of my model at any time and Solidworks breaks it into little pieces that don't easily communicate with each other.
10:20 AM archivist: gear mates make all the difference for me
10:21 AM Wolf_: http://i.imgur.com/HsI9RqP.jpg I still have one part that I made that I can’t seem to get mates to work with lol
10:21 AM Simonious: Wolf_: ha! I've made dozens of models that are very similar to that one
10:21 AM Simonious: but.. in sketchup
10:21 AM archivist: often an over constraint give that problem
10:22 AM archivist: then the ah..my cockup
10:22 AM Wolf_: one stupid idler, not a single constraint on it
10:23 AM archivist: some of the mates are added by default as you draw and insert parts to be helpful
10:23 AM Wolf_: but its not really effecting anything for me so.. oh well
10:24 AM Wolf_: http://i.imgur.com/awiDTkM.jpg everything fits when made :)
10:26 AM Wolf_: its a really weird error with that one part, won’t let me use a concentric mate
10:27 AM archivist: slide the part see what else it is mated too
10:28 AM archivist: I have had parts flying wildly with a silly set of mates
10:29 AM Wolf_: http://i.imgur.com/Tkcm7Rg.jpg
10:30 AM Wolf_: it seems to have a case of the dumbs
10:30 AM archivist: I note a highlighted hole to the right
10:31 AM Wolf_: yeah, they are suppose to be aligned lol
10:31 AM archivist: I would be using the bore not the edge of the hole anyway
10:31 AM _methods: yeah
10:31 AM _methods: but the holes should still work
10:32 AM _methods: is there some other mate under the other part
10:32 AM _methods: that might be conflicting?
10:32 AM archivist: bore is more specific and correct
10:32 AM Wolf_: 3 clicks, easy fix lol
10:35 AM Wolf_: only a inplace mate to the rail
10:41 AM Wolf_: Simonious: example to what i was saying https://www.mcmaster.com/#6627t66/=173ev2i (hopefully link works)
10:43 AM Wolf_: I use mcmaster to grab SW files of a lot of parts =)
12:26 PM IchGucksLive: Hi
12:27 PM IchGucksLive: a wounder full day in Germany is going off
12:27 PM IchGucksLive: ending
12:29 PM {HD}: I'm trying to install Nvidia drivers for Linux CNC and I get this error… Any ideas? http://i.imgur.com/9Kzul92.jpg
12:31 PM archivist: nvidia are a common cause of poor latency
12:31 PM IchGucksLive: be carfull you can take the whole system down
12:31 PM {HD}: archivist: So, don't do it?
12:31 PM IchGucksLive: USE the VGA only mode
12:31 PM archivist: I would not do it
12:31 PM IchGucksLive: i woudent go nvidia
12:31 PM {HD}: It is a new install so, I don't mind messing it up at this point. I am updating because the standard video drivers blink every 3-5 seconds.
12:32 PM IchGucksLive: not on a a CNC PC
12:32 PM Loetmichel_: IchGucksLive: nvidia isnt the problem
12:32 PM Loetmichel_: the High performance closed source drivers are
12:32 PM {HD}: It is attempting 'panel mode' every 3-5 seconds and it blinks
12:33 PM Loetmichel_: the open source drivers work pretty flawlessly here on an old install
12:33 PM IchGucksLive: nouveau
12:34 PM {HD}: I disabled nouveau drivers and it doesnt blink anymore but I don't have full resolution.
12:35 PM IchGucksLive: 1024 is pretty clear
12:36 PM {HD}: =/
12:37 PM {HD}: I read something about disabling 'dither' and/or 'force full screen redraws'...I guess I will try tweaking the current setting to get it to work.
12:46 PM {HD}: NVM...I guess the resolution is just fine. I do not know how I disbled nouveau because the installer for nvidia did it. Seems to work on what ever driver it is using now.
12:47 PM Wolf_: driver issues are a pain in the ass, this is main reason I did my mint build
12:47 PM {HD}: When I do my final clean linux cnc install when my other hardware arrives I will have to replicate this setup.
12:47 PM {HD}: Wolf_: What version of mint are you running?
12:47 PM Wolf_: mint 17
12:48 PM {HD}: Wolf_: So, you did a custom compile?
12:48 PM {HD}: 64bit?
12:48 PM Wolf_: yeah, need to do kernel build for lcnc
12:49 PM {HD}: If my cnc machine was multi purpose (email, web, music, ect.) I would definetly do a mint build. This machine once it is running will be ONLY CNC...
12:49 PM Wolf_: I think I did a 32 bit, if I did I’m going to redo it in 64 now that I have a VM running on a computer with some hp on it
12:50 PM {HD}: Wolf_: Is there good documentation for doing a custom linuxcnc build?
12:50 PM Wolf_: well, I needed a newer kernel build to get the wifi and video working
12:50 PM Wolf_: documentation yes, good… not so much lol
12:51 PM Wolf_: I used this https://forum.linuxcnc.org/forum/27-driver-boards/27253-7i80-and-7i77?start=180#62783 plus info from JT
12:51 PM {HD}: I don't want to froke out the machine. The documentation for just the default.iso say 'do not update OS'!
12:52 PM Wolf_: goggle linux mint cnc
12:53 PM Wolf_: there is a bunch of info on the linuxcnc forums
12:55 PM {HD}: Wolf_: Looks like there are some step by step write ups...using the 32 bit kernel at least...
12:57 PM Wolf_: yup
01:02 PM {HD}: Looking at the linuxcnc 'alternate install methods' only wheezy w/preempt-rt support 64bit and machine control. The other 64bit options are 'simulation only'...Mint 17+ is built on Trusty(jessie) so, I guess it would be: Not officailly supported.
01:26 PM Crom: steppernot here yet, but is on the truck
01:28 PM Crom: I installed amd-64 debian 8.7, I then added repositories for linuxcnc apt-get update; apt-get install linuxcnc-uspace
01:30 PM Crom: found the 4.9.13-rt12 linux kernel source on kernel.org, downloaded that. updated header (/usr/include, etc....) to linux-header-4.9.13-rt12
01:33 PM IchGucksLive: il keep staying mainly on 10.04
01:33 PM IchGucksLive: but do Youtube on 14.04 SIM
01:34 PM IchGucksLive: now 12.04 is goiing off this month if not in the days
01:35 PM Crom: oops downloaded linux kernel 4.9.13 then ran the 4.9.13-premptrt patch against it
01:40 PM Crom: latest rt patch is 4.9.20-rt16
01:40 PM Crom: https://www.kernel.org/pub/linux/kernel/projects/rt/4.9/
01:41 PM DrippityDrops: does this load for you guys? http://huntingtonscrew.com/linuxcnc/3.mp4
01:44 PM Crom: epileptic chuck yet
01:44 PM IchGucksLive: DrippityDrops: yes
01:44 PM Crom: yes
01:44 PM IchGucksLive: are you building a full auto lathe
01:44 PM DrippityDrops: thank you, its a profiling spindle
01:44 PM DrippityDrops: not chuck
01:44 PM DrippityDrops: imagine putting this where you tailstock is
01:45 PM DrippityDrops: but the chuck on lathe would be stationary
01:45 PM DrippityDrops: so... second operation profiling attachement we'll say
01:45 PM IchGucksLive: om off Gn8
01:45 PM DrippityDrops: seeya!
02:31 PM CaptHindsight: are people using Linux Mint LMDE or the mainstream version with LCNC?
02:33 PM CaptHindsight: I see more 18.x and 17.x talk on the LCNC forums
03:07 PM andypugh: Am I crazy to consider making my own M23 connector insert?
03:07 PM andypugh: I simply can’t find a 16-position female-contact M23 cable plug.
03:09 PM andypugh: This is what I want. Note how it is non-stock: http://www.mouser.co.uk/search/ProductDetail.aspx?R=0virtualkey0virtualkeyMA1CAE1600M-KIT
03:13 PM jdh: 12 & 19 are normal, anything else is special order?
03:15 PM andypugh: 17 is easy
03:15 PM andypugh: http://www.mouser.co.uk/search/ProductDetail.aspx?R=0virtualkey0virtualkeyMA1CAE1700M-KIT
03:15 PM andypugh: Not even expensive!
03:17 PM jdh: I have some parker servos that look like that. but I guess all round connectors look about like that.
03:21 PM andypugh: I am liking my glorified glue-gun.
03:25 PM andypugh: Looking at the M23 connectors, it actually looks like the 16 is just like the 17 with a pin missing. I will risk it.
03:28 PM {HD}: I want to buy a carbide hand scraper. Any suggestions?
03:29 PM jym: andypugh: What is this "M23" connector for?
03:29 PM andypugh: Encoder cable for a servo
03:29 PM jym: Oh, ew
03:29 PM _methods: {HD}: i have the sandvik inserted style
03:30 PM Tom_L: TGIF
03:30 PM jym: andypugh: Would it be worth it to use/ a DB connecotr instead?
03:30 PM jym: andypugh: ... now and in the future
03:31 PM andypugh: You mean dismantle the motor and change the connector? I have done that before…
03:31 PM andypugh: But I have decided that £13 and ignoring a pin is the way.
03:31 PM jym: andypugh: Maybe pigtail what you already have ?
03:31 PM jym: andypugh: I'm just not fond of "propritary" /obscure connectors is all.
03:32 PM andypugh: M23 is almost standard for servos.
03:32 PM jym: andypugh: Murphys is a dead man when I catch him, and all that
03:32 PM jym: andypugh: Right, but how standard is it on friday at 6pm =)
03:33 PM jym: and a three day weekend
03:33 PM andypugh: That’s why I am going to buy two
03:33 PM jym: lol, fair enough. Was just suggesting aDB as they REALLY are common enough =)
03:34 PM andypugh: I am £6 from free dellivery. Delivery is £12. What should I get?
03:34 PM {HD}: _methods: looks nice enough. Do you push or pull scrape?
03:35 PM jym: andypugh: pin extractor?
03:35 PM _methods: push
03:35 PM andypugh: Good point, the extractor is fairly inecpensive.
03:35 PM andypugh: (normally they are hundreds)
03:36 PM _methods: {HD}: http://www.ebay.com/itm/SANDVIK-COROMANT-620-20-CLAMP-ON-SCRAPER/272308140880
03:37 PM _methods: saves a lot of time dressing having insert style
03:37 PM _methods: when you wear out the blade just swap out and resharpen dull ones later
03:37 PM {HD}: _methods: I like it! Thanks.
03:38 PM _methods: np
03:40 PM {HD}: I understand the process of scraping and flaking for flatness. I don't get how you would do parallel or perpendicular scraping. Do you just use dial indicators?
03:44 PM _methods: i have surface sq to check against
03:45 PM jym: andypugh: Yeah I worked on enough mil connector to know you need that damn extractor and almost impossible to replicate on your own.
03:45 PM _methods: http://www.cnczone.com/forums/general-metalwork-discussion/33924-scraping-perpendicular-parallel-coplanar-surfaces.html
03:45 PM andypugh: I made my own extractor for Lemo connectors. For £3 and have enough tube left over to make 100 more ;-)
03:46 PM jym: andypugh: haha, there ya go.
03:47 PM andypugh: I found a pair of these (actually next size up) in the scrap bin at work. They didn’t stay there: http://www.ebay.co.uk/itm/Moore-Wright-Round-Leg-Inside-Calipers-Open-To-Around-4-1-2-As-Photo-/152419275154
03:47 PM jym: andypugh: I lost my metal "middle" molex extractor, now just have large and small. glad I don't need it allthe time.
03:47 PM _methods: jym: what happened to your other m's
03:48 PM jym: _methods: in storage for safe keeping.
03:48 PM _methods: heheh
03:48 PM CaptHindsight: _methods: I was just going to look for pone of those, thanks
03:48 PM CaptHindsight: pone/one
03:48 PM XXCoder: heys
03:48 PM _methods: there is a 620-30 which is a wider insert
03:49 PM CaptHindsight: have to fix up a Bridgeport
03:49 PM _methods: actually i think there are probably more than just the 2 widths
03:49 PM _methods: well you might want to get a real power scraper for a job that size
03:50 PM _methods: i don't think you'll have much fun hand scrapin a bridgeport
03:50 PM jym: _methods: is it suppose to be fun?
03:50 PM andypugh: Those scrap-bin calipers might end up costing me money. I find myself thinking about buying them a friend.
03:50 PM _methods: well i do find it relaxing
03:51 PM CaptHindsight: _methods: it's also exercise
03:51 PM _methods: it is that also for sure
03:51 PM CaptHindsight: I've been lapping the inside of a cylinder for several hours
03:51 PM CaptHindsight: wax on, wax off
03:52 PM _methods: then maybe you do want to pass on the power scraper lol
03:53 PM CaptHindsight: http://dapra.com/biax/scrapers/index.html
03:53 PM _methods: yea
03:53 PM _methods: you might be able to find a used one on ebay
03:54 PM _methods: but they're fairly hard to find it seems
03:54 PM CaptHindsight: why not a sawzall?
03:54 PM _methods: yeah
03:54 PM _methods: some people do the diy sawzall thing
03:54 PM CaptHindsight: https://www.youtube.com/watch?v=-D0NGK21Qkk

03:56 PM CaptHindsight: I think the blue dye was pretty redundant for that large plateau :)
03:59 PM JT-Mobile: howdy from Maggie Valley NC
04:00 PM XXCoder: hey
04:00 PM CaptHindsight: i think the hardest part is having to invert the mill to get the ways to slide on a surface plate :)
04:03 PM CaptHindsight: https://www.youtube.com/watch?v=_tkr4UI1fL4 this way seems much easier
04:05 PM jym: CaptHindsight: Silly, you invert the surface plate
04:07 PM CaptHindsight: jym: then raise the ways to the underside (was topside) of the surface plate?
04:08 PM jym: CaptHindsight: Yep, and then you BEND the surfaceplate to match
04:08 PM JT-Mobile: XXCoder, what's up
04:08 PM XXCoder: headachy heh
04:08 PM JT-Mobile: ouch
04:08 PM XXCoder: you?
04:09 PM CaptHindsight: jym: http://p.globalsources.com/IMAGES/PDT/B1076932718/Granite-Balls.jpg is that how these are used?
04:11 PM JT-Mobile: drove the Cherohala Skyway today it was snowy
04:11 PM XXCoder: happy blustery day here
04:12 PM jym: CaptHindsight: Nah, you need to use one of these... http://pic.stonecontact.com/picture201511/201512/60404/china-grey-granite-wash-basins-sinks-g633-granite-wash-bowls-bathroom-sinks-basins-oval-basins-sinks-kitchen-sinks-p406255-1b.jpg
04:13 PM XXCoder: fancy
04:15 PM CaptHindsight: jym: I have always wondered what those are for. They aren't drinking fountains after all
04:16 PM CaptHindsight: https://www.youtube.com/watch?v=D1eOQa1gYiU Scraping in a dovetail
04:17 PM jym: CaptHindsight: Old skool "tin foil hat", but using the natural lead, and orther toxic elements to blank the alien probes
04:17 PM jym: block*
04:18 PM CaptHindsight: look how far out the chinaco millwas
04:18 PM XXCoder: just remember that alum foil blocks all but 2 frequances, both goverment controlled.
04:18 PM jym: XXCoder: which are?
04:19 PM CaptHindsight: XXCoder: 1 tin and 1 alum is what i have heard
04:19 PM XXCoder: no idea been a while lol. mythbusters tested that
04:19 PM CaptHindsight: tin alone is just silly
04:19 PM Deejay: gn8
04:20 PM SpeedEvil: Who earlier said they were thinking of a power caulk gun?
04:20 PM SpeedEvil: http://i.imgur.com/8cIr4PZ.jpg
04:25 PM Crom: Sister had a broken roof tile.... no rain until next friday gives me a bit of time to climb up and glue it together again...
04:26 PM Crom: no steppers
04:28 PM SpeedEvil: Or find a replacement
04:28 PM Crom: no replacements.... anywhere... 20 year old concrete tile which they haven't made in 15 years
04:29 PM XXCoder: take intact one out, create mold with it
04:29 PM Crom: liquid nails roof tile glue..... works really good. Pretty damn UV stable
04:29 PM XXCoder: cast it
04:29 PM SpeedEvil: creating moulds and making fibre reinforced tile is quite doable
04:30 PM Crom: too much effort...
04:30 PM SpeedEvil: Or simply scan it and mill it from a solid block of concrete.
04:30 PM Crom: heh probe it...
04:31 PM Crom: I can vacuum form a top and bottom for a mold... heh
04:32 PM Crom: I'll do it for my house... for making PV support tiles
04:33 PM XXCoder: hmm wonder which would be better, cast concerete or make 3d model of tile and mill it out of concerete block
04:38 PM Crom: milled tile would be shiney...
04:38 PM Crom: and you would get the stones showing
04:39 PM Crom: cast. it would be concrete.
04:40 PM SpeedEvil: Milled and polished tile would be shiney
04:40 PM SpeedEvil: I wasn't being very serious, you'd have to be rather insane to form it subtractively, and not by moulding
04:43 PM JT-Mobile: the creek is very loud should drown out any highway noise lol
04:44 PM XXCoder: if creek is at your home, tap it for power generation lol
04:44 PM XXCoder: expecially if it can drown out dhighway noise!
04:45 PM Crom: I'm lusting... https://www.youtube.com/watch?v=wBD7vwcsFgk
04:46 PM Crom: cast, mill clean up....
04:48 PM Crom: 7:31 am On FedEx vehicle for delivery BLOOMINGTON, CA
04:49 PM Crom: 1.5 hours to get to town... I'm at south end.. so 6 to 8 hours...
04:50 PM Crom: definately doing an unboxing video!
05:01 PM JT-Mobile: at the motel in Maggie Valley Nx
05:01 PM JT-Mobile: NC even
05:01 PM jdh: welcome to nc
05:01 PM Crom: sheeshz... I'm as bad as the dog.... looking out the window waiting for the bringer of food and pack Alpha
05:02 PM Crom: cept I'm waiting for the white van with purple on it
05:04 PM Tom_L: JT-Mobile reached your destination?
05:04 PM XXCoder: curious whats you doing jt
05:05 PM Tom_L: JT-Mobile, are you on 2 3 or 4 wheels?
05:05 PM XXCoder: or 1 or 6
05:08 PM JT-Mobile-: 4 in the Honda Civic hybrid
05:08 PM Tom_L: better in snow than 2 or 3
05:09 PM JT-Mobile-: trying to get to the top of the mountain in Sylva NC to meet my sister and BIL
05:09 PM JT-Mobile-: yea no shit snow on 2 wheels sucks
05:09 PM Tom_L: in love with I40?
05:09 PM JT-Mobile-: been there done that
05:09 PM JT-Mobile-: I hate I40
05:09 PM Tom_L: heh
05:09 PM Tom_L: i went thru the hills at 4AM when all the truckers are out
05:10 PM Tom_L: fog and wet
05:10 PM Tom_L: they were all using the no truck lane
05:10 PM JT-Mobile- is now known as JT-Mobile
05:12 PM XXCoder: lol
05:12 PM XXCoder: I always go home at around 2 am
05:12 PM XXCoder: its basicallu quietest time for roads here
05:12 PM Tom_L: they were in such a hurry their trailers were fishtailing
05:13 PM Tom_L: gas trucks no less
05:14 PM Tom_L: can't say i blame you for not liking it
05:17 PM XXCoder: who else is talking?
05:17 PM JT-Mobile: dang wind today was insane wild
05:18 PM Tom_L: yeah it's been windy here today
05:19 PM XXCoder: !log
05:19 PM XXCoder: hmm
05:20 PM Tom_L: talk nicer
05:20 PM JT-Mobile: try log
05:20 PM XXCoder: thanks
05:20 PM XXCoder: ah somone was lol
05:21 PM JT-Mobile: that was a fun project
05:22 PM Tom_L: i've been going back thru old code for nothing better to do
05:22 PM Tom_L: like 88ish code
05:22 PM XXCoder: just careful not to turn 8 to lazy 8
05:23 PM Tom_L: good refresher
05:23 PM Tom_L: bringing it all up to the latest compiler standards
05:23 PM Tom_L: it's funny how much it changed
05:24 PM JT-Mobile: what language?
05:24 PM Tom_L: clipper
05:24 PM JT-Mobile: never did clipper
05:25 PM JT-Mobile: did foxpro
05:25 PM Tom_L: i started using it with autumn86
05:25 PM JT-Mobile: and a bit of dbase
05:25 PM Tom_L: i've still got dbase III loaded
05:25 PM Tom_L: it doesn't do Y2K
05:26 PM Tom_L: i updated some dates and had to rewrite a utility to fix them
05:26 PM JT-Mobile: I liked foxpro better
05:26 PM Tom_L: never used it
05:26 PM Tom_L: this has RDD for foxpro though
05:27 PM Tom_L: replaceable database driver
05:27 PM JT-Mobile: it started out as an independent then ms bought them
05:28 PM Crom: wooo clipper... I havent though about that in years!
05:29 PM Tom_L: i wrote a couple utilities to read a dbf and generate code to recreate it with the indexes if not found
05:29 PM Crom: used to run TBBS which on the multiline pc version was basically a dbase os
05:30 PM Tom_L: lowlevel read the dbf header and reproduce the code for it
05:30 PM Crom: last 12 years I've been using FMserver 6, it's now to something stupid... 11 or 12 i think
05:30 PM JT-Mobile: getting cold outside and no wifi inside so goodnight
05:31 PM XXCoder: noooo
05:31 PM Tom_L: later
05:31 PM XXCoder: lol later
05:31 PM Crom: nite nite
05:33 PM Tom_L: wtf, no WIFI inside? i thought that's where it was supposed to be
05:33 PM XXCoder: dont ask me no idea\
05:34 PM Crom: FMserver 7 went totally overboard oop...
06:00 PM Crom: UPS truck just went by.... Fed Ex should be close
06:00 PM XXCoder: stlking ups eh
06:00 PM XXCoder: lol funny joke
06:01 PM XXCoder: "don't fart in Apple store - they don't have windows"
06:01 PM Crom: heh
06:02 PM Crom: Loved it... picture of a Sachette Kitten (Skunk) on facebook. "Love my new kitten, but his farts REALLY stink!"
06:02 PM XXCoder: yah saw that! LOL
06:03 PM Crom: That was a cute little Skunk. I love them, Ive always had good dealings with skunks. and they keep the rats and mice down as well as snakes
06:04 PM XXCoder: heard "destunked" skunks make for good pets
06:04 PM Crom: Hate possums!
06:05 PM Crom: They do... I prefer them armed and dangerous...
06:05 PM XXCoder: lol
06:06 PM Crom: I'll leave water and kibble out for them... but i have to watch for possums....
06:06 PM The_Ball: Anyone here use a tool setter x/y/z type with linuxcnc, like the renishaw ts24r?
06:11 PM Crom: ts27r?
06:13 PM The_Ball: just like this one https://www.youtube.com/watch?v=Swn45rMa8W0
06:13 PM The_Ball: Managed to pick on up at an auction
06:13 PM Crom: hmmm that's an id... bit of rod, 45 degree chamfer at top. check length, diameter and check for broken corners
06:14 PM Crom: s/id/idea
06:14 PM Crom: USPS on the way out...
06:34 PM enleth: what is actually the proper way of zeroing lathe tools?
06:35 PM enleth: I just realized I've seen a bazillion different methods, jigs, devices and whatnot for zeroing/touching off milling cutters, but none for a CNC lathe
06:36 PM XXCoder: good question, I never setup a lathe but saw guy use built-in sensor for tool zeroing
06:36 PM XXCoder: thats extent of my knowledge lol
06:39 PM enleth: other than, maybe, on those fancy fully automated dual spindle turning/milling/drilling/boring combo machining centers, but they just do it the same way a modern milling machine would do it, having a dozen degrees of freedom on everything
06:39 PM enleth: but on a traditional lathe? dunno.
06:50 PM gregcnc: enleth you set one tool with 0.0 Z offset, face a bar, them touch off the rest of the tools
06:53 PM enleth: I imagine X offset is better done by turning a new diameter with each tool and miking it?
06:54 PM gregcnc: to being with, if you're looking for accuracy you'll be adjusting the offsets for the actual cuts on the part
06:56 PM gregcnc: that was to read: to begin with
07:18 PM CaptHindsight: real time ethernet on the Rpi3, just like Lcnc
07:19 PM CaptHindsight: http://linuxgizmos.com/raspberry-pi-based-computer-offers-real-time-ethernet/
07:19 PM CaptHindsight: ethernet controller over SPI to the rPI
07:19 PM CaptHindsight: Rpi even
07:52 PM linuxfan: hello
07:52 PM linuxfan: I have a homing problem with my linuxcnc master
07:52 PM linuxfan: anybody willing to help?
07:55 PM cradek: hey welcome
07:55 PM linuxfan: thanks
07:55 PM cradek: always go ahead and ask your question, so people can see it and decide whether they can help
07:55 PM cradek: you don't ever have to ask to ask in irc
07:56 PM linuxfan: I have a gantry machine, with dual motors on X axis, so I made configuration with joints - four joints for 3 axes
07:57 PM linuxfan: homing works, when I try to home X axis, but routine isnt the best - both joints travel towards limits, and first motor to hit limit, backs off, then second one does the same
07:58 PM linuxfan: what I would like to achieve is, that first motor to hit home, waits other motor to hit home, then both together move away from switch
07:58 PM linuxfan: otherwise one motor already backs off, and other is still going towards home, and it twists gantry
08:04 PM cradek: this looks like one successful way: https://forum.linuxcnc.org/forum/24-hal-components/30849-gantry-homing
08:04 PM cradek: (but you probably already did the obvious google search I did to find that)
08:05 PM cradek: I have not done a gantry myself
08:13 PM linuxfan: this is exactly what I try to achieve
08:48 PM DrippityDrops: I think I just found my next cnc project machine http://huntingtonscrew.com/linuxcnc/mrts.jpg
09:06 PM jym: Crom: you around?
09:06 PM cradek: I accidentally superglued a T nut into the T slot of my mill with approximately an entire tube of super glue
09:07 PM Tom_L: one drop will do...
09:08 PM cradek: one drop is not what came out when it was a bit plugged and I squeezed it
09:08 PM cradek: and to be fair, one drop would not have glued the T nut in place nearly this well
09:08 PM Crom: here... trying to figure out a stepper... it goes same direction with dir low or high
09:09 PM Crom: jmc-motor.com got here...
09:09 PM Crom: jk
09:09 PM Crom: eerrt
09:09 PM Crom: ghgh
09:09 PM Tom_L: will naptha thin it? i can't remember
09:09 PM Crom: cradek: warm it with a propane torch... it'll come loose
09:09 PM Tom_L: block the sides of the tslot and flood it with sovent
09:09 PM Crom: wow that computer was lagged
09:10 PM cradek: ooh that might be easier than taking the table off and soaking it in acetone
09:10 PM cradek: I didn't think of heat - thanks
09:10 PM cradek: hey I bet this gelled acetone stuff would burn nice
09:10 PM jym: cradek: Got Marshemllows?
09:10 PM cradek: nope, vegetarian
09:10 PM Crom: heat evenly...
09:11 PM jym: Crom: Is PEx the same as yellow gas tubing?
09:11 PM Tom_L: mmmm i'm trying to enclose quotes inside quotes to become part of a string.
09:11 PM Crom: if you have plumbers torch even better... just warm the tnut
09:11 PM DrippityDrops: i just kinda roughly counted, I got about 25 mesa cards
09:11 PM Crom: jym: whatcha need?
09:11 PM DrippityDrops: just from building junk
09:12 PM jym: Crom: the yellow gas tubing isn't a "stocked" item, but PEX is.
09:12 PM Crom: Tom_L: "\" or """" bklah """"
09:13 PM Tom_L: crom this is clipper
09:13 PM Tom_L: something like ' "" '
09:13 PM Crom: PE yellow gas is 3 times thicker than pex
09:13 PM Tom_L: i think it changed a bit over the versions
09:14 PM Crom: chr$(34) I think
09:14 PM jym: cradek: ah, ok
09:14 PM Tom_L: i didn't have to do it with summer 87
09:14 PM Tom_L: ^^ that worked
09:14 PM Crom: it was a basicish syntax
09:14 PM Tom_L: i'm converting working s 87 code to 5.2
09:14 PM jym: Crom: Ah, ok. Well, for a temperoary setup, thik it'll work? Not deteriorate formthe propane?
09:16 PM Crom: yeah for temp...
09:16 PM Crom: nah, propane won't do a thing to it...
09:16 PM Crom: Clipper/Xbase compatible compiler ... KS_F CHR(70) + CHR(33) #define KS_G CHR(71) + CHR(34)
09:16 PM cradek: heat worked!
09:17 PM jym: Crom: Ok, cool. I just need to find a quick connect fitting, that's been the difficult part.
09:17 PM Crom: no $... forgot that
09:18 PM Crom: how quick? union and 2 channel locks works too
09:19 PM jym: Crom: lol, okey that's one idea. Do I need to teflon/dope a union?
09:19 PM Crom: nope :) no dope
09:19 PM jdh: clipper. 2017
09:19 PM jym: Crom: no yellow teflon either?
09:19 PM Crom: quarter valve each side... then a union
09:20 PM Crom: quarter turn valves
09:20 PM jym: Crom: Yeah HD donet have any 3/4"
09:20 PM Tom_L: problem located
09:21 PM jym: Crom: This is all I could find http://www.homedepot.com/p/3-4-in-Brass-FPT-x-FPT-Lever-Handle-Gas-Ball-Valve-VGV1LHB4EB/205812148
09:21 PM Crom: on the threads to the nipples to the valves yes.. on the union itself no...
09:22 PM Crom: nipples to the outside of the union yes as well
09:23 PM Crom: PEx shark to 3/4 ball valve to FPT
09:23 PM jym: Crom: shark fittings for gas?
09:24 PM Crom: it's PEx right?
09:24 PM jym: yeah
09:25 PM cradek: next time I'll make sloppier T nuts
09:25 PM * jym lol @ Crom
09:25 PM jym: err cradek
09:25 PM jym: damn nick completion
09:25 PM jym: Crom: Got Vegan marshemllows?
09:25 PM jym: I give up
09:26 PM {HD}: Yikes my jitters are over 200k!
09:27 PM jym: Crom: You have no idea how temped I'm to using garden hose fittings
09:27 PM Tom_L: Crom, too many dimensions in the array
09:32 PM Crom: did you predimension it?
09:32 PM Crom: WOOOOOOOO 40mm/s
09:32 PM Tom_L: no
09:32 PM Tom_L: but i had too many dimensions
09:32 PM Tom_L: with AADD you don't need to rebuild it
09:34 PM XXCoder: jym: that is why I set auto-complete to spoken order then abcs for rest of nicks that match but havent spoken while I was here.
09:34 PM XXCoder: makes it work better
09:35 PM Crom: no idea...
09:35 PM jym: XXCoder: but both are here right now and both are speaking. I usually do 12<TAB>, but bot CR<TAB> is Crom and cradek
09:35 PM Crom: WOOOOOO HOOOO 60mm/s !
09:35 PM XXCoder: aww poor jym lol
09:36 PM Crom: now to figure out how to clear alarm... and rehome
09:36 PM XXCoder: Crom: 60 mm/s on machone? pretty good
09:37 PM XXCoder: whats your jitter on computer
09:37 PM Crom is now known as Corm
09:37 PM XXCoder: {HD}: not as bad as my laptop I first tested for linuxcnc lol it was over 250k
09:37 PM XXCoder: compare to current old computer I use for linuxcnc - less than 15k lol
09:38 PM Corm: 3.6m/m NICE!
09:39 PM Corm: jitter sucks... but I'm running closed loop steppers...
09:39 PM * jym remaps XXCoder voice control to elmer fudd!
09:39 PM Corm: so who cares... :)
09:39 PM XXCoder: ah yea would get bunch of data on int
09:39 PM XXCoder: so jitter is higher
09:39 PM XXCoder: jym: they all sound same to me so I dont care.
09:40 PM jym: lol
09:40 PM XXCoder: wow https://airandspace.si.edu/stories/editorial/how-being-deaf-made-difference-space-research
09:41 PM Corm: 60mm/s on Z is stupid!
09:41 PM Corm: with a 75mm Z travel
09:41 PM {HD}: XXCoder: This is my old equipment I am just trying to build some config files for my drivers then I will move to my new hardware when I get the parport I ordered.
09:41 PM XXCoder: Corm: whole second of travel time!
09:45 PM XXCoder: so in time it took for ping to fail he'd have traveled 10800 mm lol
09:46 PM XXCoder: err no
09:50 PM {HD}: Power scrapers seem very un percise.
09:52 PM XXCoder: no I was right. sucks trying to do math when has major headache
09:55 PM robi is now known as Corm
09:56 PM XXCoder: how was your travel of 10800mm
09:56 PM Corm: sadly,,, I can only travel 372mm but I can go it in style
09:57 PM XXCoder: heh you took 180 seconds to time out
09:57 PM XXCoder: so at 60 mm/s thats 10800mm
09:58 PM Corm: more like 7seconds
09:58 PM Corm: heh
10:00 PM Corm: I want to go beyond stupid fast, I want to go ludicrously fast!
10:00 PM Corm: oh quassel has no speel check
10:01 PM jym: wouldn't ludicrously actually be SLOWER than stupid fast?
10:01 PM Corm: Space balls go to ludicrous speed
10:01 PM jym: ah, my bad
10:02 PM enleth: what about plaid speed?
10:02 PM XXCoder: <-- Corm has quit (Quit: No Ping reply in 180 seconds.) :P heh
10:02 PM jym: Corm: Now, I just need to see if I can use hose clamps.... http://www.homedepot.com/p/SharkBite-1-2-in-Brass-PEX-Barb-x-3-4-in-Male-Pipe-Thread-Adapter-UC116LFA/202270582
10:06 PM {HD}: where do i find "driver characteristics" data?
10:07 PM {HD}: Should I just set everything to 20K?
10:07 PM Corm: driver characteristics?
10:07 PM {HD}: In the stepconf
10:08 PM Corm: time the driver requires to see a pulse... and lead time after dir changes before sending a pulse for step
10:09 PM {HD}: How do I determine the values?
10:09 PM Corm: tb6600 takes 10000,10000,20000,20000... new steps take 2500,2500,6100,6100
10:09 PM Corm: steppers
10:09 PM jdh: they are specified in your driver docs
10:09 PM DrippityDrops: {HD}: get your new lpt?
10:10 PM Corm: my new steppers take...
10:10 PM {HD}: DrippityDrops: No, I am using the old tower to just fimilarize my self with linuxcnc and get some config files sorted out before my parport showsup.
10:11 PM {HD}: jdh: Ill double check my chinese driver PDFs
10:11 PM DrippityDrops: you have not used linuxcnc on hardware yet?
10:11 PM {HD}: DrippityDrops: No, I am trying it for the first time. I am a long time mach3 user.
10:12 PM DrippityDrops: awesome
10:12 PM DrippityDrops: which machine and controller you putting this with?
10:13 PM {HD}: DrippityDrops: I built a small machine using my big machine a few weeks ago. I am rebuilding my big machine into a hybrid gantry style but, I wanted to have a small machine to continue making the parts I need for the new-big...
10:14 PM DrippityDrops: awesome again, you should document everything
10:14 PM DrippityDrops: =D
10:14 PM {HD}: I am currently using wantai drivers
10:14 PM XXCoder: document document making also ;)
10:15 PM DrippityDrops: so, just directly driving steppers via lpt?
10:15 PM {HD}: and the wantai drivers have no specific data on step times...
10:16 PM {HD}: DrippityDrops: Yes, PAR - BOB - DRIVERS
10:16 PM DrippityDrops: oh okay, I guess I was asking which "bob" you were using
10:17 PM {HD}: DrippityDrops: OH, its a "CNC Stepper Motor Driver 6 Axis Interface Board adapter - with Optical isolation, protect your PC"
10:17 PM {HD}: chinese thing
10:17 PM XXCoder: I just use BOB and 3 tb6600s
10:18 PM XXCoder: orginially used tb6560 but that sucked
10:18 PM {HD}: XXCoder: the 6600s are a good price. What are you driving with them? 23s?
10:19 PM XXCoder: nema23 yeah
10:19 PM DrippityDrops: pretty slick
10:19 PM {HD}: DrippityDrops: I read that cheap optocuplers can really slow things down so, if I notice that I will either bypass the optos or upgrade the bob.
10:19 PM DrippityDrops: nice size too
10:20 PM DrippityDrops: I had to admit I am 500% exceedingly happy with mesa cards
10:20 PM DrippityDrops: if you havent made a choice yet, look into them IMO
10:20 PM Corm: OH MY GOD! the JMC-Motor.com 2nm stepper is FULL OF AWE!
10:21 PM Corm: NEMA 23 2nm 285ozin... so worth the $114 each!
10:22 PM XXCoder: lol aliexpress similiar for 10% price
10:22 PM Corm: jitter... don't care... as long as the motor gets a step close to where I want it... 60mm/s!
10:23 PM Corm: closed loop ROCKS!
10:23 PM {HD}: Corm: link? What makes them special? That seems expensive.
10:23 PM {HD}: OH, closed loop...
10:23 PM Corm: Integrated closed loop stepper.
10:23 PM Corm: Driver/encoder/motor all in one
10:24 PM XXCoder: closed loops = knows when it didnt move when it was supposed to
10:24 PM Corm: search ebay 2nm NEMA 23 integrated closed loop stepper
10:24 PM {HD}: XXCoder: So it knows it did something wrong but still doesnt care?
10:24 PM XXCoder: lol
10:24 PM Corm: I think a 1nm 142ozin would be fine for a 3040 and 6040
10:26 PM Corm: {HD}: it knows when it's not to where it's supposed to be and then corrects are best it can. If it goes TOO far out it'll alarm, which triggers estop if you wire it that way
10:26 PM XXCoder: http://www.ebay.com/itm/3-Phase-57-Nema23-1N-m-Hybrid-Closed-Loop-Stepper-Motor-and-Driver-Kits-1500rpm-/172611481089
10:26 PM XXCoder: cheapest one there
10:26 PM Corm: lead shine... external driver...
10:27 PM {HD}: So its just a stepper with an encoder on the back...Seems cool enough. I havent really had any issues with missed steps if I config the machine correctly.
10:30 PM Corm: http://www.ebay.com/itm/262565317443
10:30 PM Corm: I got 3 of these
10:31 PM {HD}: That controller is not 'built in' it is 'stuck on' but, still cool I like the idea of more percision.
10:31 PM Corm: oh 60mm/s on 23vdc!
10:31 PM XXCoder: one of problem with my machine is steppers has no flat spot
10:31 PM Corm: these do
10:31 PM XXCoder: I should take em out and grind em but whatever later
10:32 PM Corm: what size grub screw takes a 1,5mm allen key?
10:32 PM DrippityDrops: I wonder how close we are to putting linuxcnc embedded, controller, amplifier, stacked directly on a motor with daisychain connectivity
10:32 PM Corm: 3mm?
10:34 PM Corm: close... Power brick -> raspberry pi 3 -> BOBhat -> iHSS57 (my steppers) -> ...
10:34 PM DrippityDrops: it all needs to be in an aluminum extruded enclosure packed tights but safe in vibration, magnetic field and heat.
10:34 PM Corm: get the motor which take ethernet..
10:34 PM DrippityDrops: I wonder if we could pull it off
10:35 PM DrippityDrops: every motor has its own instance lcnc and when you connect two motors they ask for their location in the system and all work in unison as a extendable cnc platform
10:35 PM DrippityDrops: sorry I keep getting you all off track LOL
10:36 PM DrippityDrops: but ya know.. that would be the shizzzz
10:36 PM {HD}: DrippityDrops: That would be cool. How would they know which motor is which?
10:36 PM DrippityDrops: beowulf
10:37 PM DrippityDrops: and..... just a kinematics interface
10:37 PM DrippityDrops: so you assign each joint to motor
10:38 PM Corm: BOBhat takes it from 3.3v to 5v... MtrGnd MtrPwr, data 5v, step-, dir-, alarm-, enable-, peb-
10:39 PM Corm: hmmm ethernet... Gnd pwr, t- t+ r- r+, t- t+ r- r+ 1,3,4,5 data 2,6,7,8 gnd pwr and daisy chain
10:40 PM Corm: 2+7 gnd 6+8 pwr
10:45 PM Corm: 1 rev is 1600 or 4mm, 0.000 098" less than a tenth for one step and I'm getting 60mm/s !
10:46 PM Corm: 0.0025mm per step
10:46 PM {HD}: metric...bah!
10:47 PM DrippityDrops: base 12 system > than base 10
10:48 PM XXCoder: base4! > base 12
10:49 PM {HD}: does microsteps per rev effect how hot the motor gets?
10:49 PM Corm: heh change step to 1/256000 60mm/s becomes 0.3787mm/s
10:50 PM Corm: {HD}: these stay pretty cool... encoder is holding position... it'll fire coil as needed
10:51 PM Corm: hmmm... do I leave stepper on back... or move y to front...
10:51 PM Corm: on back
10:52 PM {HD}: what do you guys shoot for as far as steps per inch? I have my drivers set as low as they go for microstepping...currently.
10:54 PM {HD}: OMG this seems like a really good idea... http://i.imgur.com/7m7zDYZ.gifv
10:54 PM Corm: I'm doing just over 2"/s
10:55 PM R2E4_bevins1: the more microstepping you have the less torque....
10:55 PM XXCoder: lol hd
10:55 PM XXCoder: I think mine is currently set to 4
10:55 PM XXCoder: plenty of torque for what i want.
10:56 PM {HD}: I am running nema34s so why over powered for what they are doing...I could microstep the crap out of them.
10:58 PM XXCoder: lol
10:58 PM XXCoder: 64 microstep ;)
11:00 PM Corm: 8 microstep right now... but that's less than a 1/1000 of an inch per step
11:00 PM {HD}: my drivers seem crazy...I can set it to 51200 steps per rev...
11:01 PM {HD}: that would be 256000 steps per inch...
11:01 PM XXCoder: man up and go 64 ;)
11:03 PM {HD}: I guess Ill try to get my home switches working now...
11:13 PM {HD}: That was easy. They just happened to be set up correctly already.
11:14 PM XXCoder: lots of watt wolves here
11:15 PM {HD}: What exactly does that mean?
11:16 PM XXCoder: no meaning really, joking about wolf_100w
11:17 PM {HD}: What are you guys set your maximum velocity to? 20 inches a second?
11:17 PM XXCoder: mines at I think 100 mm/s
11:17 PM DrippityDrops: I try not to break the sound barrier when I rapid
11:17 PM XXCoder: can be faster but why
11:18 PM {HD}: DrippityDrops: lol
11:19 PM DrippityDrops: {HD}: do you have a cnc lathe too?
11:19 PM {HD}: DrippityDrops: not yet. Why?
11:19 PM XXCoder: if your machine makes doppler sound chanegs when doing rapids, you might want to cut down max speed.
11:19 PM DrippityDrops: {HD}: lathes are super handy, I just wondered what kind of setup you had and were striving for
11:21 PM {HD}: DrippityDrops: I think I'll start with just putting a small fourth axis on. Eventually I want to have a dedicated CNC lathe.
11:21 PM XXCoder: one of things I want to try is rig a shitty 4th axis
11:22 PM DrippityDrops: how big is your mill?
11:22 PM XXCoder: just wood rod mounted on stepper
11:22 PM {HD}: Can I add a home all button to my toolbar?
11:23 PM {HD}: My mini machine I just built is 25" x 13" of machinable area. My new machine will be just over 5 feet in both axis.
11:23 PM XXCoder: NRA employee shoots himself acciently. hah.
11:23 PM DrippityDrops: lol
11:23 PM DrippityDrops: I mean thats not funny
11:24 PM XXCoder: sure its not, the funny partt is that guy is supposely professiona;
11:24 PM {HD}: XXCoder: video?
11:24 PM DrippityDrops: {HD}: in axis if you have your homing sequence set already there should be a HOME ALL option
11:24 PM XXCoder: why?
11:24 PM DrippityDrops: are you asking if it can be placed up above?
11:25 PM {HD}: Yes. I want my home all button to be somewhere on the primary interface.
11:25 PM {HD}: Is there a Homo hockey?
11:25 PM {HD}: Lol Siri!
11:25 PM {HD}: You know what I'm trying to say.
11:25 PM DrippityDrops: if you read into the "HOME ALL" button and the HOMING SEQUENCE it will explain how to attain that HOME ALL button
11:26 PM XXCoder: yeah youre trying to say homo cocks ;)
11:28 PM XXCoder: aaand channel killed. :P
11:28 PM DrippityDrops: oh indeed jolly good show
11:28 PM {HD}: Ha
11:29 PM DrippityDrops: {HD}: read section 3.9 of the homing sequence stuff. It tells you exactly what you need to do you to INI file to do what you need
11:30 PM {HD}: DrippityDrops: cool. When I get back upstairs I'll pull it up.
11:40 PM {HD}: DrippityDrops: I don't see anything about adding the home all button to the toolbar.
11:40 PM {HD}: I see the hotkey ctrl+home
11:40 PM XXCoder: it is auto added I think once you have script configured?
11:41 PM XXCoder: not area im familiar with.
11:41 PM {HD}: XXCoder: How do you homeall? the hotkey?
11:42 PM XXCoder: I dont use home all, I just manually home all 3 axis
11:45 PM DrippityDrops: have you already got the HOME ALL button on the interface?
11:45 PM DrippityDrops: if not
11:45 PM DrippityDrops: then you have not set your homing config properly
11:45 PM DrippityDrops: if you have the homing config set properly the HOME ALL button will replace the HOME AXIS button
11:45 PM DrippityDrops: {HD}: ^
11:46 PM XXCoder: yeah, on my main computer linuxcnc sim has home all where home axis is at linuxcnc computer.
11:46 PM XXCoder: since sim is already configured correctly
11:46 PM {HD}: I can hit the 'home all axis' in the drop down menus and it works correctly.
11:47 PM {HD}: Maybe there is a home button on the interface/toolbar and I am just not seeing it...
11:47 PM DrippityDrops: {HD}: can I see you INI?
11:47 PM XXCoder: hd, you have home axis button in manual?
11:48 PM {HD}: DrippityDrops: Shut down the CNC machine for the night. I am back in my office.
11:49 PM {HD}: Ill poke it again in the morning.
11:49 PM DrippityDrops: just compare your INI to the sample INI which DOES have the HOME ALL button in place. it should show you your error
11:49 PM {HD}: DrippityDrops: Cool. Thanks.
11:50 PM {HD}: Thanks again for the help...Ill have this thing figured out soon I hope.
11:50 PM {HD}: Later.
11:50 PM DrippityDrops: np! I spent awhile messing around with it myself
11:50 PM DrippityDrops: take care
11:51 PM XXCoder: have fun hd
