05:03 AM XXCoder: hey jthornton you alive?
05:07 AM jthornton: yea
05:07 AM XXCoder: did you see quadcoper that dives into water and "fly around" there? and can get out and fly out
05:08 AM jthornton: no
05:08 AM XXCoder: its interesting
05:08 AM XXCoder: https://www.youtube.com/watch?v=FC9EJhs0pc0
05:12 AM IchGucksLive: hi
05:13 AM XXCoder: hey maker of cncs
05:13 AM IchGucksLive: xc i need to make more
05:13 AM IchGucksLive: iv been anounced 5400 + students this year
05:13 AM IchGucksLive: only 12 mashines present
05:13 AM IchGucksLive: at that university
05:13 AM XXCoder: dang!
05:13 AM XXCoder: maybe 1,000 of those $150 cnc routers'
05:14 AM IchGucksLive: so i need to get awallins cutsim intergreated into vismach
05:14 AM IchGucksLive: i will ask a other school to get 12 from there
05:15 AM IchGucksLive: and they changed now to fusion at my advice
05:15 AM XXCoder: its pretty good from what I see, and free for students, so not surpised
05:16 AM IchGucksLive: better then solid
05:16 AM IchGucksLive: but i like to teatch on ProE
05:17 AM IchGucksLive: as it is a VRMl not a Nurbs system
05:17 AM IchGucksLive: and on design level of today this woudt be also the best
05:31 AM IchGucksLive: hi TekniQue
05:31 AM IchGucksLive: XXCoder: woudt be good if awallin shows up but he is bussie in the worrld
05:31 AM XXCoder: apparently heh
05:32 AM IchGucksLive: noon here goiing for dinner
05:32 AM IchGucksLive: bye till later
05:42 AM jthornton: my server keeps rebooting on it's own... I need to find a modern MB for it
05:47 AM XXCoder: lol modern take on old game https://www.youtube.com/watch?v=Ll9wMALZJxY
05:52 AM jthornton: I wonder why the damn MB keeps rebooting
05:54 AM XXCoder: dunno, heat issues?
05:54 AM XXCoder: or dead battery
05:54 AM jthornton: hmm could be
05:55 AM XXCoder: cmos battery can cause all kinda weird shit when dying
05:58 AM jthornton: the cpu fan is working and cool air from the other side
06:02 AM jthornton: might be the power supply
06:02 AM XXCoder: hmm unstable or micro brownouts
06:02 AM jthornton: if it was a power issue I'd have 10 pc's rebooting
06:03 AM XXCoder: no, the psu micro brownout
06:03 AM XXCoder: it cant suppy enough dc
06:03 AM jthornton: ah yea
06:03 AM jthornton: I have a couple of power supplies
06:04 AM jthornton: hmm the one in that box is a newer one
06:05 AM XXCoder: dont fporget to check cmos battery as that can do strange stuff
06:14 AM jthornton: battery ok
06:22 AM XXCoder: thats good
08:49 AM -!- #linuxcnc mode set to +v by ChanServ
10:15 AM Deejay: bbl
11:09 AM Loetmichel: *huurrhurr* wife of the boss was behind me all day, wanting to learn how to solder... (dont think she will ever learn it, she cant even see the 0402 parts let aline handle and solder them :-)... so i accidentally rammed a small steel sliver into my left hand. Toook an xacto knifen and pryed it out.. Bosswife: "Ihhh... blood. Shall i call an ambulance?" $me" no thanks its just a sliver." She:"
11:09 AM Loetmichel: a bandaid then?" $me (sucking on the wound to get it stop bleeding) "MHMHMHMHM NAH! not neccessary!" *pours Isopropane alcohol over the small gash* "*SSSH* See, done! Doesent even bleed any more." ... then she fled the workshop ;)
11:16 AM skunkworks: self mutilation seems appropriate in those situations.. Sort of like chewing off your leg when in a trap...
11:19 AM * JT-Shop likes his HikVision IP camera :)
12:41 PM Tom_itx: JT-Shop, how's clarity at 100-200' ?
12:41 PM Tom_itx: license plate readable?

01:47 PM IchGucksLive: 13death in spain
02:06 PM IchGucksLive: im off Gn8
03:02 PM phipli: bleh
03:02 PM phipli: late home
03:11 PM JT-Shop: hey
03:11 PM XXCoder: hey'
03:14 PM phipli: evening both
03:15 PM XXCoder: whats up
03:15 PM phipli: :)
03:15 PM phipli: long day
03:15 PM phipli: got some leave planned
03:15 PM XXCoder: nice
03:15 PM phipli: which means I have to basically do a load of the work I'd do now :s
03:15 PM phipli: workLogic--
03:15 PM phipli: but, yes
03:16 PM phipli: on the plus side, I have some leave
03:16 PM XXCoder: heh I havent used any of my vacation hours
03:16 PM XXCoder: its over 100 hours now
03:16 PM phipli: thankfully there are rules in work that I have to take them
03:16 PM phipli: I'm not very good at taking leave
03:17 PM XXCoder: my coworker had over 300
03:17 PM phipli: I used to end up just taking it all in Deccember
03:17 PM phipli: ours don't roll over
03:17 PM phipli: why do you count it in hours?
03:17 PM XXCoder: but he had 3 week long vacation, noiw mid-200
03:17 PM XXCoder: its how vacations work here
03:17 PM phipli: US?
03:17 PM XXCoder: for some companies anyway
03:17 PM XXCoder: yeah
03:18 PM phipli: we get about 4 weeks - the internet tells me you folks don't take a huge amount of holiday
03:18 PM Tom_itx: ok, ready to test the spindle again. it'll either go or blow
03:18 PM XXCoder: heh yeah, that really depends on company here
03:19 PM phipli: out of 4 weeks I'd taken about 2 days 6 months in
03:19 PM XXCoder: in my case, first 3 years is one week a year, or 40 hours
03:19 PM XXCoder: after that, 80 hours a year, then increasing again after 5 years to 120
03:19 PM phipli: don't you get exhausted over time?
03:19 PM XXCoder: or 3 weeks. still quite below yours
03:20 PM phipli: what is normal working hours per week for you folks? (general population)
03:20 PM XXCoder: not really, otherwise I'd have taken a vacation by now
03:20 PM XXCoder: 40
03:20 PM phipli: heh
03:21 PM phipli: technically we're about 38... but in reality everyone works unpaid overtime
03:21 PM phipli: UK it known for it
03:22 PM JT-Shop: chicks are in transit to Poplar Bluff so I will get the little fuzz balls in the morning :)
03:25 PM phipli: excellent :)
03:25 PM phipli: ours were in bed when I got home
03:25 PM FinboySlick: JT-Shop: Are you trying to emulate Keith Fenner?
03:26 PM JT-Shop: I'm putting a 5' chain link fence around the coop
03:26 PM JT-Shop: dunno who that is...
03:26 PM FinboySlick: JT-Shop: Youtube machinist who also has chickens.
03:27 PM JT-Shop: oh, I don't watch much youtube... can only watch between wake up and 8am
03:27 PM * JT-Shop goes back to work for a couple more hours
03:46 PM gloops is now known as Goodlord
04:19 PM phipli: So mouser want me to send a scan of my passport or drivers licence before they'll send me my stuff...
04:20 PM phipli: yeah.
04:20 PM phipli: thats not happening
04:20 PM phipli: sooner cancel the order
04:20 PM XXCoder: wtf
04:20 PM phipli: for my security don't you know
04:21 PM phipli: because banks don't already provide payment protection stuff
04:23 PM JT-Shop: what do you need from mouser?
04:25 PM phipli: Ordered an SBC
04:25 PM phipli: checking around to see who else has them in stock
04:25 PM djdelorie: maybe it's export controlled?
04:25 PM phipli: nope
04:26 PM djdelorie: maybe you're on the sbc watch list? ;-)
04:26 PM phipli: It is probably my fault - I generated an email address for the order that had "mouser" in it
04:26 PM phipli: I think you're thinking of ICBMs
04:27 PM djdelorie: intercontinental business with mouser?
04:27 PM phipli: on a lighter note : https://mobile.twitter.com/ftcreature/status/898243415506378752/video/1
04:27 PM phipli: djdelorie: yup, that is what I'm trying to do
04:27 PM phipli: although they won't take my monies
04:27 PM XXCoder: flying mouse
04:27 PM phipli: (should probably check to see if they have actually)
04:27 PM XXCoder: or whatever thats called
04:28 PM phipli: Guinea Pig
04:28 PM phipli: quite a jump
04:28 PM phipli: never owned one, but we had one at my first school
04:28 PM phipli: they're quite friendly
04:33 PM Frank_20: anyone knows a good quality brand planetar gear reduction for servos?
04:35 PM JT-Shop: usually the servo manufacturer makes reduction gears for the servos, what brand are the servos?
04:53 PM Tom_L: in dmesg using pwmgen how should the direction pin show up? all i see is GPIO
04:53 PM Tom_L: and all i get from the pin is a short pulse
04:55 PM Tom_L: [ 7362.001637] hm2/hm2_7i90.0: IO Pin 019 (P1-39): PWMGen #0, pin Out0 (PWM or Up)
04:55 PM Tom_L: [ 7362.001624] hm2/hm2_7i90.0: IO Pin 017 (P1-35): IOPort
04:58 PM Tom_L: something's fishy
05:04 PM mrme_: Tom_L what possibilities you have in pncconf?
05:05 PM Tom_L: i don't use wizzards
05:06 PM mrme_ is now known as mrme
05:08 PM Tom_L: dammit, i wish there was a way to compare the config on the board to my .vhd file
05:08 PM mrme: Tom_L what config possibilities you have?
05:08 PM mrme: prehabs connect the io to the direction signal
05:08 PM Tom_L: i don't know what you're asking
05:08 PM mrme: with hal
05:09 PM Tom_L: i checked the setp stuff in hal already
05:10 PM mrme: how is it connected?
05:12 PM Tom_L: should be thru the hm2 driver
05:12 PM Tom_L: i'm going to do some more investigating...
05:12 PM Tom_L: bbl
05:35 PM phipli: https://www.riskbasedsecurity.com/2016/10/please-email-us-your-pii/
05:36 PM phipli: that person's post ends with mouser saying they'll change the wording. Shame that I got the exact same message 10 months later!
05:44 PM malcom2073: Heh gg mouser
05:53 PM * JT-Shop wonders where the wife is...
05:54 PM phipli: getting pizza?
05:56 PM BeachBumPete: http://i.imgur.com/g2Q8kaZ.jpg ;)
05:58 PM Tom_itx: JT-Shop, do you know if the direction pin is supposed to show up in dmesg like the PWMGen output does?
05:58 PM Tom_itx: using hm2 pwmgen
05:59 PM Tom_itx: something has to be screwed up in this config
05:59 PM Tom_itx: but i'm not sure which .vhd file it was i used and i can't compare it against the loaded bitfile
06:00 PM Tom_itx: has to be the same datestamp
06:10 PM Tom_itx: i think i may need to fix my bitfile
06:13 PM JT-Shop: Tom_itx: I don't think they show up as hal pins
06:13 PM JT-Shop: maybe pcw_home will chime in...
06:16 PM Tom_itx: the problem is, when my hdd crashed the .vhd i had got corrupt. well i have backups but i don't know exactly which one i was using
06:16 PM Tom_itx: i'm gonna go about rebuilding the .vhd and make a new bitfile so i know what i've got
06:17 PM Tom_itx: so i've been relying on the loaded bitfile not knowing exactly what it was
06:19 PM JT-Shop: what is a .vhd?
06:24 PM CaptHindsight: vhdl file for the fpga
06:28 PM Tom_itx: JT-Shop, it's the source for the bitfiles
06:29 PM Tom_itx: what i think happened is, originally i needed spindle pwm but it had no reverse so i didn't enable the direction pin in the .vhd file
06:29 PM Tom_itx: now that i've added reversing i think i need to add the direction back into the mix
06:29 PM Tom_itx: that and enable
06:30 PM Tom_itx: i think i'm gonna start fresh with a .vhd and make it match the current IO functions
06:30 PM Tom_itx: this thing has changed quite a few times
06:30 PM Tom_itx: i did however wire up your relay and test it out using +5v as the trigger instead of an IO pin
06:31 PM Tom_itx: 5v -> opto -> 24v relay
06:32 PM Tom_itx: and originally i was using a 7i43 and now i'm using the 7i90
06:33 PM Tom_itx: and went from a 7i47 to 7i47S which kills a few IO for the spindle control
07:35 PM ola: I have a friend who has a shopbot prt which he is willing to part with. I am new to cnc, but I have been doing some reading. I am a developer, and I have used linux almost exclusively for several years. Does anyone here have an opinion on upgrading a shopbot so that linuxcnc can be used to control it? I was thinking of buying the machine and getting a gecko g540 and maybe a super-pid. Has anyone here done this, or similar?
07:53 PM malcom2073: ola: What size steppers does it have?
07:55 PM malcom2073: shopbots are fairly large, I'd imagine you'd need something bigger than a g540
07:55 PM malcom2073: That being said, decent sized stepper drivers are fairly cheap if it does indeed have steppers
08:02 PM CaptHindsight: ola: http://www.shopbottools.com/mProducts/prSalpha.htm this shopbot??
08:02 PM CaptHindsight: http://www.shopbottools.com/mProducts/PRS_specs_compare.htm
08:08 PM ola: malcom2073: I don't know what steppers it has. I hope to see it in person this weekend. It has whatever motors the early model shopbot prt came with. From what I've read, I think it's either a direct driving oriental vextra pk299 or a geared pk296-sg.
08:09 PM jdh: http://www.shopbottools.com/mSupport/controlsoftware.htm
08:09 PM malcom2073: Wow, isn't the shopbot a 4x8?
08:09 PM malcom2073: That's an awefully small stepper
08:10 PM ola: It's a 4x4
08:10 PM malcom2073: Ah alright
08:10 PM malcom2073: Ah the former isn't too bad, 800oz/inch
08:10 PM malcom2073: G540 is still a bit small, but you can get inexpensive 4-6A stepper drivers
08:10 PM malcom2073: Then use a parallel port PC, or a mesa card to drive them
08:13 PM ola: I want to upgrade the thing to something more usable without it hitting my wallet too hard. Like I said, I'm new to cnc. What is the advantage of using a mesa card rather than a parallel port?
08:14 PM CaptHindsight: https://www.automationtechnologiesinc.com/products-page/g540-stepper-motor-kits/gecko-diver-g540-4-axis-driver/
08:14 PM CaptHindsight: ola: there might not be any, it depends on the application
08:14 PM jdh: I bought a g540. was amazed by how physically tiny it is
08:14 PM CaptHindsight: A Mesa FPGA can step faster than an LPT port but that might not be of use to you
08:15 PM CaptHindsight: how fast can your machine step reliably? then run the numbers
08:15 PM CaptHindsight: latency jitter on the LPT port
08:16 PM CaptHindsight: see how fast your chosen PC can step and then see if you want or need to use an FPGA card
08:16 PM ola: I guess I'll buy the it and find out. Thanks for the advice. I have to get out of here, but I'll be back tomorrow.
08:17 PM jdh: prob wouldn't cost much to convert regardless.
08:17 PM CaptHindsight: ola: run the latency test on the PC first
08:17 PM CaptHindsight: how fast do you want/need to step?
08:18 PM jdh: anyone know where I can get a dial-indicator tip that is a roller/ball-bearing?
08:19 PM CaptHindsight: like clamp a bearing and axle onto a dial indicator?
08:19 PM jdh: like, unscrew the tip and scrrew in a axle/bearing tip
08:19 PM jdh: starrett makes one but it is like $50 for the tip
08:20 PM CaptHindsight: look for used is all then
08:21 PM CaptHindsight: https://www.amazon.com/Roller-Contact-Point-Dial-Indicators/dp/B007IBTDHU
08:21 PM jdh: http://www.starrett.com/metrology/product-detail/25W
08:21 PM jdh: yeah, that but cheap
08:22 PM CaptHindsight: https://www.zoro.com/starrett-roller-contact-point-for-dial-indicators-25w/i/G0667301/feature-product
08:22 PM CaptHindsight: not sure of the shipping
08:22 PM jdh: really looking for harbor freight quality/price vs. starrett
08:22 PM CaptHindsight: http://www.wttool.com/index/page/product/product_id/42075/product_name/Roller+Anvil+Special+Dial+Indicator+Contact+(USA)
08:23 PM jdh: there are kits of 30 various non-roller tips for $10
08:23 PM CaptHindsight: there you go
08:23 PM CaptHindsight: of what value are they if they aren't made well?
08:24 PM CaptHindsight: like having a solid jello surface plate?
08:24 PM CaptHindsight: or wooden dial indicator
08:52 PM jdh: looks like the Starrett ones are actually on the cheap end.
08:54 PM enleth: KUKA KR200 is finally arriving today
08:55 PM enleth: I wonder if it's going to run right off the bat
08:55 PM X704 is now known as tiwake
08:55 PM enleth: the control appears to be fine after a couple minor repairs
08:56 PM enleth: servo drives all green and all
08:56 PM jdh: what payload?
08:58 PM enleth: 200kg dynamic, 500kg theoretical safe static
08:58 PM enleth: it's pretty big
08:58 PM jdh: wow
08:59 PM enleth: it's a machining-capable arm, not a welder accessory
09:01 PM enleth: spec sheet lists milling, machine tending, material handling and assembly
09:02 PM jdh: what is machine tending
09:03 PM enleth: putting stock into VMCs, presses, brakes, etc. and pulling finished parts out
09:03 PM jdh: cool.
09:04 PM enleth: sometimes holding the stock during processing, usually sheet metal in a brake
09:04 PM jdh: I have some baby ABB's at work. Think they are 3kg max. still pretty nifty
09:05 PM enleth: https://hackerspace.pl/~spin/kukulka/image3.jpg forklift for scale
09:07 PM CaptHindsight: I'm sure you could program it to make pancakes
09:07 PM enleth: it's not terribly rigid for milling but handles huge workpieces with the help of an external rotary table
09:07 PM CaptHindsight: machine large blocks of foam
09:08 PM CaptHindsight: lots of uses
09:08 PM enleth: exactly
09:08 PM enleth: lost foam casting, resin forming, vacuum forming, etc.
09:09 PM enleth: big RC model parts
09:09 PM CaptHindsight: are you going to use its controller or convert to LCNC?
09:10 PM enleth: if the controller actually works, I'll use it for now
09:10 PM enleth: but it's ancient
09:11 PM enleth: Windows 95 running as a VxWorks process
09:13 PM enleth: obvoiusly converting it is not going to be easy
09:15 PM enleth: the encoders, brakes, etc. are muxed on some kind of a digital bus
09:17 PM enleth: it's either reverse engineering it, or modding the arm itself to replace the built-in logic
09:18 PM enleth: which is something I'd rather not do
09:19 PM enleth: OTOH, I do intend to take it apart like the bridgeport
11:06 PM Tom_itx is now known as Tom_L
