01:37 AM dave_: still looking at 4th axis solutions - https://www.omc-stepperonline.com/closed-loop/nema-34-closed-loop-stepper-motor-70nm1001ozin-encoder-1000cpr-34hs38-4204d-e1000.html
01:40 AM dave_ is now known as gloops
01:40 AM gloops: stepper with encoder/closed loop, y/n?
01:40 AM archivist: yes no maybe
01:42 AM archivist: if a proper encoder then you can attempt to hold to a position
01:45 AM gloops: stepper might have advantage there anyway - as normal state is still
01:48 AM archivist: pdf says not a lot about the encoder
01:49 AM gloops: no not much info
01:50 AM archivist: from the db15 wiring, no index
01:51 AM archivist: 4 connections so differential
01:52 AM archivist: use a normal driver and let linuxcnc see the feedback
01:55 AM gloops: well it would be controlled by step/dir driver
01:56 AM gloops: the encoder signal with that is going to a db port though?
01:57 AM gloops: not to a parport pin/s
02:00 AM archivist: note parallel ports have limited speed, linuxcnc loop speed
02:01 AM gloops: https://www.ebay.co.uk/itm/100W-NEMA23-Integrate-Servo-Motor-Drive-Controller-Encoder-Pulse-Direction-36V/122187547998?
02:02 AM gloops: yes i read a forum thread where someone said parport limits encoder signals to 10-15kHz in real terms his machine was restricted to 120 ipm
02:03 AM gloops: thats plenty for rotary wood id say
02:04 AM gloops: the ebay link gives some more info on what the encoder does
02:04 AM gloops: looks a nightmare for a newb to wire up though
02:06 AM archivist: my version of the hobbing setup is using a parallel port and reading an encoder, so it has a 100 line encoder to keep the rpm up
02:06 AM gloops: theres one thing if you make your own encoder you know what is happening
02:07 AM gloops: i dont understand yet what that stepper encoder is doing, how it works
02:07 AM gloops: you would by the time you got it working though heh
02:07 AM archivist: it is a normal encoder as far as I can see
02:08 AM gloops: so that would suffice?
02:08 AM archivist: yes, probably best with a mesa card though
02:08 AM Deejay: moin
02:11 AM gloops: it starts getting expensive to just learn and play, stepper/encoder, mesa card, spindle vfd other steppers and drivers
02:11 AM gloops: suppose all can be transferred to the real machine
02:21 AM archivist: you can use the motors full speed with a mesa card
02:21 AM archivist: but then just you can use a normal servo :)
02:23 AM gloops: https://www.ebay.co.uk/itm/6-Axis-NVEMv1-1-CNC-200KHz-Ethernet-MACH3-Card-Breakout-Interface-Motion-Board/162051580739?
02:23 AM gloops: 200 kHz
02:24 AM Deejay: re
02:29 AM gloops: mesa still does not appear on uk ebay
02:31 AM archivist: buy direct/jt not on ebay
02:36 AM monkeyisl: https://imgur.com/a/zh5Ff
02:37 AM monkeyisl: i'm still waiting for another parts to be here.
02:38 AM monkeyisl: bbl
02:59 AM _Patang is now known as Patang
02:59 AM monkeyisl: gloops buying mesa?
02:59 AM gloops: not atm, bbl
03:19 AM Contract_Pilot: Hey all
04:15 AM Contract_Pilot: Had to upgrade my cable modem today sheesh
04:16 AM Contract_Pilot: end of life on my modem no longer supported for the 150/20 business calss plan. I was only getting 115MB down
04:17 AM Contract_Pilot: now averaging 170's when connected directly to the new modem
04:18 AM Contract_Pilot: have a Asus Rapture GT-AC5300 connect via ethernet only device = 60's WTF
04:19 AM Contract_Pilot: Think it must be a router setting...
04:19 AM Contract_Pilot: Wifi i am onlhy getting 30's was getting 7- prior to modem change
04:19 AM Contract_Pilot: 70's
04:28 AM enleth: jeez, this is the most ridiculous home router I've ever seen
04:29 AM enleth: Contract_Pilot: so you're getting less than 100Mbit/s *wired*?
04:29 AM Contract_Pilot: Yep to the router
04:30 AM enleth: check if it negotiates a gigabit link with the modem
04:30 AM Contract_Pilot: Connected directly to the cable modem 170's
04:30 AM enleth: it does have a GbE WAN port, but it sounds exactly as if it only negotiated a 100Mbit link, while the provider is still trying to push data at 150
04:30 AM enleth: which causes packet drops and retransmissions
04:30 AM Contract_Pilot: http://www.stevenrhine.com/wp-content/uploads/2017/12/F4A50731-8B1B-4B66-B0AA-0B6739E89B14-1024x768.jpeg
04:31 AM enleth: but if it's GbE on both sides, then no idea
04:31 AM Contract_Pilot: Have to figure that out
04:33 AM enleth: this seems to be a general trend with cable modems that they behave *very* badly if the connection is more than 100Mbit but whatever's connected to them is only 100
04:33 AM enleth: I've seen it multiple times, so that's the first thing that comes to mind
04:34 AM enleth: if that's not it, maybe call Asus
04:36 AM enleth: this thing costs a fortune, let them prove that this money wasn't wasted
04:37 AM Contract_Pilot: Yea
04:38 AM Contract_Pilot: with nothing else connected just the cable modem hooked to the wan and 1 PC it should get full speed i owuld think.
04:38 AM enleth: I ordered some MikroTik hardware a couple days ago to upgrade my home network and I spent about half of what this costs on a router/AP combo with PoE out, a managed switch and a secondary PoE AP
04:39 AM enleth: and I was worried I spent too much
04:39 AM enleth: and overdesigned it
04:40 AM Contract_Pilot: RJ45 for 10/100/1000/Gigabits BaseT for WAN x 1
04:40 AM enleth: yeah, but it might have negotiated 100Mbit only
04:40 AM enleth: try a different cable, for one
04:41 AM Contract_Pilot: 1st thing i did hahaha
04:41 AM Contract_Pilot: bth cables modem to router and router to pc
04:42 AM enleth: well, see if that router actually indicates negotiated connection speeds
04:43 AM enleth: if they're both GbE, and there are no suspicous settings enabled, well, call Asus
04:45 AM Contract_Pilot: looking to see how to find that info
04:45 AM enleth: oh, one more thing
04:45 AM enleth: check MTU settings
04:45 AM enleth: they cause voodoo problems like this too
04:46 AM enleth: all across the whole stack, starting with the MTU recommended for your current subscription by the cable provider
04:49 AM enleth: and the obvious - run ping 8.8.8.8
04:49 AM enleth: see if there are any drops
04:49 AM enleth: start a big download while ping runs
04:49 AM enleth: see if the timings or drop rates change
04:55 AM enleth: Contract_Pilot: ^ (highlighting in case this gets you on the right track faster)
04:57 AM Contract_Pilot: ok
05:00 AM Contract_Pilot: BRB
05:13 AM jthornton: morning
05:13 AM XXCoder: yo
05:13 AM XXCoder: freezing cold here heh
05:13 AM XXCoder: first for this winter
05:14 AM jthornton: 29F here at the moment
05:18 AM XXCoder: cold.
05:26 AM XXCoder: good, my kindle is "refueled" for next couple weeks heh
05:26 AM XXCoder: uploaded 18 more books to it
05:26 AM * jthornton doesn't know what a kindle is lol
05:26 AM XXCoder: kindle paperwhite, an eink reader
05:26 AM Contract_Pilot: back
05:29 AM Contract_Pilot: maybe it is this modem may have to change it to another brand
05:51 AM XXCoder: https://www.youtube.com/watch?v=N0A4dpmo1qM
05:51 AM XXCoder: $20 for one of those bar of pewler.
05:51 AM XXCoder: I wonder if its worth ut'
05:55 AM XXCoder: want to evenually play with cnc router to make molds to cast pewler
06:01 AM Contract_Pilot: Oddd
06:01 AM Contract_Pilot: Rebooted the modem and now getting full speed on the lan now.
06:02 AM Contract_Pilot: looks like my modem config file changed also
06:02 AM XXCoder: jthornton: https://www.youtube.com/watch?v=82udBDNEBHE
06:02 AM Contract_Pilot: wifi hitting about 90mb
06:03 AM XXCoder: interesting though im no artistic guy just cnc mill molds lol
06:05 AM Tom_L: 31°F
06:07 AM jthornton: makes me dizzy watching it lol about 1x too fast
06:07 AM XXCoder: 1x too fast lol
06:08 AM Contract_Pilot: I di unplug the NAS?
06:08 AM XXCoder: ah he cast wax on it
06:09 AM XXCoder: or she \
06:09 AM XXCoder: anyway so making new mold with it to cast pewler
06:20 AM XXCoder: pretty cool display at end
08:26 AM JT-Shop: damn never ending paypal issues
08:33 AM SpeedEvil is now known as Guest42443
08:37 AM BitEvil is now known as SpeedEvil
08:51 AM miss0r: I fucking finaly cracked the code, of what was wrong with the damn VFDs
08:51 AM miss0r: Apparently it is not capable of running in 'manual' with a serial addon card installed. So I had to unplug that card and add two jumpers in order for the VFD to work like it should, which now it does
08:53 AM hazzy: miss0r: Great! Just in time too :)
08:53 AM miss0r: 'round here its almost 4 in the afternoon
08:54 AM gregcnc_: so did you sleep?
08:54 AM miss0r: I called the seller this morning, and he told me that, so I could do that replacement on the fly, so I was completely ready to go install it. BUT then the guy I had an arrangement with, called to rescedule... lol
08:55 AM pcw_home: JT-Shop: we setup paypal maybe 10 years ago and had so many issues we vowed to _Never_ deal with them again
08:55 AM miss0r: gregcnc_: Yeah I squeezed in a few hours
08:55 AM miss0r: I just have a small order to take care of today (maybe 3 hours) then I'm off to bed :)

09:15 AM JT-Shop: pcw_home: what cc service do you use?
09:24 AM pcw_home: Authorise.net
09:27 AM skunkworks: we are using worldpay here.. I don't know how well it works.
09:38 AM DaViruz_: miss0r: how's the vfd work go?
09:38 AM DaViruz_: how'd
09:39 AM DaViruz_: oh, read above
09:39 AM DaViruz_: goodie
09:44 AM JT-Shop: pcw_home: thank, I assume you have a merchant account?
09:44 AM pcw_home: Yes
09:46 AM JT-Shop: otherwise the fees are higher than paypal
10:04 AM IchGucksLive: hi
10:05 AM monkeyisl: hi
10:09 AM hazzy: I am drawing a blank on how to invert HAL pins. I thought I remember just adding a -not like hm2_5i25.0.gpio.010.in-not but that does not work
10:09 AM hazzy: what am I missing this time?
10:11 AM George: Hi guys,I have a 3040 cnc which came with tb6560 motor drivers and Im searching for some documentation for them.
10:11 AM George: They have a row of 7microswitches but I cant found them anywhere.
10:12 AM George: If this helps... https://imgur.com/a/Fe8hh
10:12 AM IchGucksLive: hazzy: hm2_5i25.0.input-03-not
10:12 AM herbert__: hey! total amateur sitting in front of a Hitachi WJ200 5.5kw planning to wire it to my cnc-setup. any hints?
10:12 AM archivist: George, look for a model number on the driver box
10:13 AM IchGucksLive: George: just use stepconf its in there
10:13 AM JT-Shop: hazzy you can get a list of all the hal pins pretty fast
10:13 AM JT-Shop: http://www.mesaus.com/info/mesa-pins.txt
10:14 AM George: IchGucksLive: I just want to find what are all microswitches do,any other drivers I found on the net have 6 micro switches in a row and another 3 singles
10:15 AM George: the chip is tb6560
10:15 AM archivist: George, not the chip the model of the black box it is in
10:15 AM IchGucksLive: George: you can put all 12 switches in a row on linuxcnc
10:16 AM George: they are with no box
10:16 AM George: and the only I van see on them its TX14207
10:17 AM George: but with this number I also found nothing about them
10:18 AM archivist: some ebay sellers of the boards show switch settings
10:18 AM IchGucksLive: archivist he will get it if he plugs in the board on HAL show
10:18 AM George: Thnx a lot I'll try on ebay
10:19 AM hazzy: JT-Shop: Thanks!
10:21 AM JT-Shop: np
10:28 AM archivist: heh just as I thought I had found an ebay listing with the same layout with info he goes
10:38 AM herbert__: Do I (nessecerily) need a Gecko G540 to drive a VFD (WJ200) with HAL in linuxcnc or can I wire the VFD directly to the parallel port that I am using for all the other stuff I am driving?
10:39 AM archivist: some BOBs have pwm filters built in for 0-10v
10:40 AM pcw_home: There are basically 2 ways to drive most VFDs, Analog and ModBus
10:40 AM pcw_home: Some very cheap BOBs (Ebay 5 Axis BOB for example ) have the analog filter Archivist mentions
10:41 AM archivist: like this type http://www.collection.archivist.info/archive/mirror/cnc/bob/$_57.JPG
10:42 AM herbert__: and if so I can wire the 0-10V output from my parallel port directly to the VFD? (If I figure where to put it :D)
10:42 AM archivist: I use one of those to my vfd
10:43 AM herbert__: and in stepconf it would be Spindle PWM, CW or CCW?
10:45 AM archivist: direction is not so well catered for on that bob, use any output pin but check voltage levels
10:47 AM herbert__: we use a BOB from Benezan Electronics, only thing I know now is that it has this 0-10V thingy used for driving a spindle. It's Version 8. A german producer, not very common internationally I guess...
10:47 AM archivist: I wire my vfd for one direction and use the relay to enable the vfd
10:52 AM herbert__: what is the difference of the PWM and the CW/CCW? are all three analog voltages or is the 'Spindle PWM' setting in Stepconf used for digital signal?
10:53 AM archivist: CW/CCW and enable are logic levels
10:53 AM archivist: pwm is logic filtered to analogue
10:54 AM archivist: average on/off time=level needed
10:59 AM herbert__: is there a manual for stepconf that explains what all this pinout options mean? I can't find any reference in the documentation... :/
11:00 AM miss0r: Is there anything as refreshing as a dinner with your 2 year old son, whom has a cold and is tired?! I mean, who doesn't love uncontrollable crying & throwing stuff in all directions. That is all I need to get into the christmas spirit...
11:00 AM miss0r: p.s. I know sarcasm doesn't translate well on IRC, but I think this one gets through anywayh
11:01 AM archivist: herbert__, stepconf is just a simple helper application, to hal connections in linuxcnc which is documented
11:01 AM herbert__: archivist: hmm... ok
11:02 AM Beachbumpete: I have had mine wired via modbus for some time now. Works perfectly fine unfortunately I need to change it over to analog input because I need to use a tool changer for Orient. But I'm using a wj200 - 110 LF as well
11:03 AM herbert__: Beachbumpete: oh, so you could ship me your hal and ini in a pastebin-vessel so that I can get a better understanding through an example??? ;)
11:03 AM archivist: herbert__, basically it just fills an ini and a hal file for you, they are just text files
11:03 AM Beachbumpete: I probably could if I was at home near the machine LOL
11:04 AM Beachbumpete: Mine has a setup for forward and reverse control as well as outputs for spindle load metering in RPM
11:04 AM archivist: except pete is using a mesa card so quite different
11:05 AM Beachbumpete: Archivist actually the modbus plugs directly into the PC
11:05 AM herbert__: is it like a total benefit to use a mesa card? I could aquire one :)
11:06 AM jthornton: herbert__: look in the documents under stepper configuration
11:06 AM archivist: can be, depends on your machine
11:06 AM Beachbumpete: I would highly recommend Mesa cards if you can afford it. Both of my machine are are set up with them no complaints whatsoever
11:08 AM herbert__: Beachbumpete: in the beginning we were struggeling with a decision for/against mesa cards because we just couldn't figure what kind of computer would be necessary for that, what latency values would we get, which mainboard to use for it and so on and so on so we swiched to the small BOB instead. Any recommendations for an upgrade to a mesa card?
11:08 AM jthornton: miss0r: everyone gets cranky when they don't feel good
11:09 AM miss0r: jthornton: Sure :) Don't get me wrong, I love the little man, but stuff like that takes a toll
11:09 AM jthornton: herbert__: latency is not a big an issue with a mesa card as it is with software step generation
11:09 AM Beachbumpete: Will be back later guys got to get back to work. Have a good day
11:09 AM jthornton: see ya pete
11:10 AM jthornton: herbert__: let me get some motherboard's I'm currently using
11:10 AM archivist: herbert__, it is the opposite, BOB is more fussy
11:11 AM * jthornton notices that lunch minute is over and goes back to the shop
11:13 AM pcw_home: 100-200 usec latency is OK with a hardware stepgen, but will limit a software (parport) stepgen rather severely
11:19 AM herbert__: jthornton: that would be great!
11:30 AM miss0r: I'm supposed to do some cutouts in 20 plastic enclosures (280x280x130). And just now, litteraly as i'm moving the mouse to press excecute on the first one, the customer calls and tells me theres been a change of plan, and the holes i'm supposed to cut are to be altered... *sigh*
11:33 AM SpeedEvil: yay!
11:33 AM SpeedEvil: But doh.
11:34 AM jdh: re-engineering fee
11:35 AM miss0r: absolutly. But I was hoping tonight wouldn't be as late as last night
11:36 AM archivist: more moneyz
11:37 AM herbert__: you are getting money for what you are doing? dang, I am doing sth wrong
11:38 AM miss0r: not alot, mind you. I don't do this for a living
11:51 AM Contract_Pilot: BBL
11:53 AM JT-Shop: aww he left
11:55 AM JT-Shop: seen herbert__
11:56 AM JT-Shop: poor guess I see
11:56 AM archivist: !seen herbert__
11:56 AM the_wench: last seen in #linuxcnc 2017-12-06 17:33:28GMT 00:19:27 ago, saying you are getting money for what you are doing? dang, I am doing sth wrong
11:56 AM JT-Shop: ah thanks
12:05 PM IchGucksLive: hi
12:07 PM IchGucksLive: hi bodden how windy is it up there
12:07 PM boddenkreuzer: windy!
12:08 PM Deejay: snow for the weekend
12:08 PM boddenkreuzer: hopefully not
12:08 PM Deejay: why not?
12:08 PM Deejay: its winter, it has to snow
12:08 PM boddenkreuzer: its not winter yet!
12:23 PM FinboySlick: Can I poke some of the electronics heads in here? I have a busted chip that says '5JLN5' in it. It appears to only have two leads so it could be a diode or somesuch Only thing google comes up with is a pipolar transistor but I have no idea where I'd find a new one.
12:23 PM JT-Shop: you let the magic smoke out?
12:24 PM FinboySlick: Yes, lots of magic in that one.
12:24 PM FinboySlick: All three on that side of the board went boom.
12:24 PM archivist: picture?
12:25 PM FinboySlick: archivist: You want a picture of the non-blown up ones to help, or do you just want to revel in the carnage of the busted ones? ;)
12:25 PM archivist: hehe
12:26 PM archivist: to get an idea of the item
12:27 PM archivist: I dunno what board and therefore what the function could be
12:29 PM FinboySlick: https://pasteboard.co/GWZpH7r.jpg
12:29 PM FinboySlick: It's a solar charge controller.
12:30 PM archivist: schottky diode probably
12:31 PM archivist: one knows it is a diode by the PCB reference numbers
12:32 PM IchGucksLive: BYW29
12:32 PM archivist: the hard part is finding the real number, they use shortened numbers on surface mount parts
12:33 PM IchGucksLive: its a 100 so use 200 and you are fine
12:34 PM miss0r: I don't like having plastic chips all over the place
12:34 PM IchGucksLive: servus elektron_ vile shcnee in der gegend
12:35 PM IchGucksLive: oh i need to go early to bed hard day as examinas are on
12:35 PM SpeedEvil: Schottky diode of Vmax > solar panel input (or battery input), and Imax of a couple of times the inptu current should generally be fine
12:35 PM SpeedEvil: Assuming it's not killed other stuff of course
12:36 PM IchGucksLive: today we talk about michels part
12:36 PM IchGucksLive: and he is not here
12:36 PM FinboySlick: All three in this picture blew up.
12:36 PM IchGucksLive: thats fine
12:36 PM IchGucksLive: yesterday i solderd 168 1w led
12:36 PM SpeedEvil: the three diodes are all in parallel
12:36 PM IchGucksLive: and gave them 11V as 2V rated
12:37 PM IchGucksLive: nice shine
12:38 PM FinboySlick: IchGucksLive: How did you come up with that part number, btw?
12:38 PM archivist: that partnumber is not in that case style
12:39 PM IchGucksLive: agrees
12:41 PM archivist: the makers logo is similar to fujitsu
12:41 PM SpeedEvil: It looks like a reverse protection diode, simply removing it would let you see if it still works.
12:41 PM SpeedEvil: (the rest of the thing)
12:41 PM SpeedEvil: and is probably a good first step to seeing if you should bother more about finding the diodes
12:41 PM FinboySlick: SpeedEvil: Apparently it still works. I'm just looking to replace it.
12:41 PM SpeedEvil: ah
12:41 PM FinboySlick: The board still works, that is.
12:42 PM SpeedEvil: Including that input?
12:42 PM FinboySlick: The diode exploded.
12:42 PM FinboySlick: I'm not sure. It was pulled off a site that was operational.
12:42 PM FinboySlick: Maybe they weren't using that part.
12:45 PM gregcnc_: methinks SMCJ130A
12:47 PM IchGucksLive: DO-214AB
12:47 PM IchGucksLive: is makt ghk
12:48 PM gregcnc_: I could be wrong my degree is in google not EE
12:48 PM IchGucksLive: gregcnc_: thats the smbj170
12:48 PM IchGucksLive: 600 Watt Transient Voltage Suppressors
12:50 PM gregcnc_: idk both vishay and littlefuse listed that
12:50 PM IchGucksLive: gregcnc_: you are right faicild uses smc
12:51 PM archivist: effin password on the datasheet
12:51 PM gregcnc_: http://www.mouser.com/ds/2/240/Littelfuse_TVS_Diode_SMCJ-62645.pdf
12:51 PM gregcnc_: https://www.vishay.com/docs/88394/smcj.pdf
12:51 PM IchGucksLive: http://search.datasheetcatalog.net/key/DO-214A
12:52 PM archivist: do--- is just the package
12:53 PM IchGucksLive: archivist as im a old metalll worker
12:55 PM gregcnc_: it seems it would take significant voltage/current to blow?
12:56 PM archivist: if the GHK is the real making then unidirectional SMCJ130A, but.... the logo is not littlefuse
12:57 PM archivist: 209v 72A that would get hot
12:59 PM IchGucksLive: im off Gn8
01:00 PM archivist: FinboySlick, was there any lightning around?
01:00 PM FinboySlick: Could well have been, yes.
01:01 PM archivist: may have done their job and died to save the rest
01:01 PM archivist: and fuses gone as well
01:01 PM archivist: any
01:14 PM miss0r: as absolutly unlikely as it sounds, after I get payed for this order, this X-carve has made me as much as it would cost to buy a new x-carve... The thing can actualy make money :o
01:15 PM SpeedEvil: :)
01:15 PM SpeedEvil: yay
01:16 PM gloops: good to hear
01:16 PM gloops: (and doesnt sound unlikely to me)
01:17 PM miss0r: Its just that the x-carve is a shitty machine (this one is upgraded, but still somewhat shitty) and still quite expensive. I didn't think it would last long enough to turn a profit
01:34 PM gloops: did have a look at the x carve briefly - the design, some vids showing owners bending the Y beam simply by pressing lightly on the collet, but can be stiffened up
01:35 PM gloops: how much could you make with an 8x4 cutting at 600 ipm
01:43 PM miss0r: gloops: I got mine for free... well, I had to tow away a trailer full of garbage for it - so I did. Then I set about stiffening it up. I also added a dewalt router to it
01:43 PM miss0r: Pretty good for cutting plastics
01:44 PM gloops: what drive is it - belt?
01:44 PM miss0r: and wood. I made a pretty awesime subwoofer enclosure with it, if I should say so myself
01:44 PM miss0r: yeah
01:46 PM miss0r: I would never go about upgrading it with ballscrews, much less acme thread. that would be a waste of time
01:46 PM gloops: well you probably got enough to do with the metal maching, and running a router is a full time job i guess, but they can earn their keep
01:47 PM gloops: for now anyway, must be another 10000 diy routers added to the global pool every week heh
01:47 PM miss0r: Nope. I haven't got enough. Enough is when I can securely quit my daytime job and do this full time
01:47 PM miss0r: I'm still hoping to kick in the door on the proto typing market. That is where I want to be :]
01:48 PM gloops: proto-types of what?
01:48 PM gregcnc_: anything of course
01:49 PM miss0r: Machine parts/small machines. even some electronics for said machines
01:49 PM miss0r: I do a decent amount of spare parts for the classic car club in town
01:50 PM miss0r: either people want part A to do B or part A is not cummercially available anymore
01:51 PM gregcnc_: as long as they understand what shops rates are
01:51 PM gloops: make cars
01:51 PM miss0r: I'm still keeping the prices down, to gain a bit more reputation
01:51 PM miss0r: not too much thou :]
01:51 PM archivist: pricing is the hard part
01:52 PM archivist: and china has spoiled pricing
01:52 PM gloops: facebook page - some impressive pics - stuff for cars, kit cars, custom cars, classic cars
01:53 PM gloops: youll soon get some attention, car freaks spend lots, every penny they get
01:54 PM miss0r: I should get a facebook page....
01:55 PM Tom_L: gotta love social media
01:55 PM gloops: stupid stuff, chromed headlamp grill, ally or stainless oil tank, fancy tig welding
01:55 PM miss0r: This is the stuff I am cutting as we speak: http://picpaste.com/IMG_20171206_205304-98bO4cKS.jpg
01:56 PM miss0r: the enclosure lid is 280x280mm. machining time is 1minut, 49 seconds each
01:56 PM gloops: whats that?
01:56 PM miss0r: custom electric outlet panel for some laboratory somewhere
01:57 PM gloops: ahh right
01:58 PM archivist: too lazy to take the label off!
01:59 PM gloops: https://www.facebook.com/MK-Engineering-259362037458423/?ref=br_rs
01:59 PM miss0r: archivist: its hard to tell, but it is wrapped in a thin plastic cover, where the sticker is on. I'm leaving the cover for protective reasons - quite easy to remove
02:01 PM archivist: I used to use a local company for my panel work, they also screen printed
02:02 PM archivist: not much money when doing 50/100 off
02:03 PM miss0r: I'm also doing this for peanuts. Please do send me your work from now on :] and never mind the shipping fee to Denmark :P
02:06 PM gloops: thats someone in our village, made some money with kits cars, his own designs and so on, sold that business, retired to his own workshop on the house, never out of work
02:06 PM miss0r: livin' the dream
02:06 PM archivist: that work dried up, not doing it anymore
02:08 PM gloops: once you get a rep for doing one off stuff, seems to be a lot of people who turn up and ask - think you can make one of these
02:09 PM archivist: can you make 50 of these....
02:09 PM miss0r: Thats where the money is, if you know what you are doing
02:09 PM miss0r: Sadly, I dont :)
02:12 PM archivist: we had a random person drop into the clockworks (mechanical) and asked about an electronic clock, we made about 2k of them
02:12 PM gloops: its only common sense - archivist can tell you how make anything
02:12 PM archivist: http://www.collection.archivist.info/archive/DJCPD/PD/2003/2003_01_23_Electronics_clock/P1240676.JPG
02:13 PM gloops: what were they for archivist?
02:14 PM archivist: price it for a low qty then haggle with the suppliers for lower prices, more profit
02:14 PM archivist: gloops, when you go into corner shop is there a clock on the cigarette display
02:15 PM archivist: amused me when my local shop had one
02:15 PM gloops: ahh, those
02:17 PM archivist: had to make a "work alike" of http://www.collection.archivist.info/archive/DJCPD/PD/2003/2003_01_23_Electronics_clock/PB120511.JPG
02:17 PM miss0r: :]
02:17 PM archivist: the clock chip was no longer available, so used a microcontroller
02:18 PM cradek: what's with all the diodes? was the display incandescent?
02:18 PM miss0r: Now, thats the sort'a orders I would love to have land here. Sounds fun
02:18 PM archivist: cradek, the old one was LED but they used diode multiplexing
02:19 PM archivist: I used latches instead
02:20 PM archivist: other side http://www.collection.archivist.info/archive/DJCPD/PD/2003/2003_01_23_Electronics_clock/P1030613.JPG
02:20 PM archivist: couple of LS374
02:21 PM archivist: and some ULN200x could use that board as a stepper driver
02:25 PM miss0r: Actualy, set aside the flimsyness of the x-carve, the most crippeling factor is the grbl controller
02:26 PM archivist: upgrade !
02:26 PM miss0r: yeah. It can't even handle 3 axis at a time!
02:31 PM miss0r: its a bit weak on the axial side... Not good for drilling
02:33 PM miss0r: and you would not believe the dc motor they slapped an ER11 collect on and called a spindle, LOL
02:34 PM archivist: seen those spindles on fleabay
02:35 PM miss0r: who in their right mind would go get that? It couldn't even properly engrave on wood, due to radial play
02:44 PM archivist: they dont have a right mind until they have used a bad spindle
03:04 PM hazzy: My niece noticed this on her box of cereal this morning (look at the fine print): https://i.imgur.com/S98c2if.png
03:06 PM Jymmm: lmao.... Mmmm IT's even MORE tasty when you zoom in!!!
03:08 PM hazzy: Either somebody had a sense of humor (seems unlikely), or the box was printed in China :D
03:09 PM hazzy: Dang, I have to draw up some parts in Solidworks, which means I have to go into windows for a bit
03:09 PM hazzy: so long fellows
03:10 PM Roguish: hazzy: chatzilla for windows
03:10 PM hazzy: It won't run on the new Firefox :(
03:10 PM Roguish: i have mine running seperate from firefox
03:11 PM Roguish: standalone. works fine
03:11 PM JT-Shop: hexchat no problems with linux or windoze
03:11 PM hazzy: Roguish: I'll have to give that a try! Thanks
03:11 PM Roguish: np
03:12 PM hazzy: haxchat causes my PC to crash, who know why
03:18 PM hazzy: ha, Thunderbird has IRC support! I did not know that
03:23 PM miss0r: There we go. Last enclosure lid of the night :)
03:24 PM miss0r: I'm off people. Have a good one.
03:33 PM hazzy: Now it is sleeting :(
03:45 PM JT-Shop1: Ha I'm chatting in tbird lol
03:45 PM JT-Shop1: not sure I like the interface or not
03:46 PM Deejay: gn8
03:46 PM hazzy: The interface is growing on me
03:48 PM hazzy: On a renishaw type probe, does one of the three "legs" need to be isolated from the others? I can't see why it would be necessary, but I took apart a crashed probe a while back and I think it was that way
03:57 PM nallar is now known as Ross
04:05 PM toastydeath: hazzy, no, the probe isn't electrical in most probes
04:06 PM XXCoder: hey toasty
04:06 PM toastydeath: sup XXCoder
04:07 PM XXCoder: not much just getting ready to go work
04:11 PM XXCoder: bleh dont feel like going today, but gonna go. later
04:20 PM hazzy: Ah, of course at least one of the probe spiders needs to be isolated! If not the circuit would remain closed unless two of the three spider legs lifted off their BBs at the same time.
04:21 PM hazzy: That also explains why it DOES matter in what orientation you put a renishaw probe back together in
04:21 PM hazzy: Since they only have one leg isolated
04:54 PM CaptHindsight: https://youtu.be/Zzg0i2ckgzc?t=53s Flink applied on 3d surface
05:03 PM CaptHindsight: is G-code used for programming robots dedicated to machining operations?
05:10 PM CaptHindsight: http://www.irbcam.com/
05:19 PM CaptHindsight: anyone work with STEP-NC? https://en.wikipedia.org/wiki/STEP-NC
05:32 PM Tom_L: someone here had a bunch of robotic arms iirc
05:32 PM Tom_L: i forgot who
05:41 PM rene-dev: I have a bunch
05:42 PM CaptHindsight: Seiko cartesian in N.C.
05:43 PM CaptHindsight: it looks very fragmented between robot makers
05:44 PM CaptHindsight: you can start with G-code and then it has to be translated to whatever the robot uses for control
05:59 PM TekniQue: so... anyone know a tool to rotate G code or a way to swap the X/Y axis or something?
06:00 PM TekniQue: I'm trying to engrave stuff using a tool that converts truetype to g code, but it only outputs in one orientation
06:06 PM CaptHindsight: http://www.scorchworks.com/Gcoderipper/gcoderipper.html
06:06 PM CaptHindsight: https://forum.linuxcnc.org/38-general-linuxcnc-questions/30068-rotating-g-code-within-linuxcnc
06:08 PM rene-dev: there doesn not seem to be a way to get the machine position via a gcode parameter
06:10 PM CaptHindsight: http://www.practicalmachinist.com/vb/cnc-machining/probably-been-asked-1000-times-free-g-code-editor-advanced-edit-functions-324909/
06:11 PM toastydeath: TekniQue, most controls have coordinate axis control
06:11 PM CaptHindsight: https://www.cnccookbook.com/g-code-simulator-viewer-generator-gwizard/
06:12 PM toastydeath: which control are you using
06:12 PM CaptHindsight: http://www.cimco.com/software/cimco-edit/overview/
06:13 PM TekniQue: toastydeath: Axis/LinuxCNC
06:14 PM CaptHindsight: TekniQue: ^^ several previous discussions and the results
06:17 PM toastydeath: the link CaptHindsight posted from linuxcnc indicates (to me anyway) linuxcnc has the rotation stuff in it
06:18 PM TekniQue: cool, thanks
06:18 PM toastydeath: kinda unusual but this is the direct link from the forum
06:18 PM toastydeath: http://linuxcnc.org/docs/html/gcode/g-code.html#gcode:g10-l2
06:19 PM TekniQue: next question, if I accidentally touch off the wrong coordinate system, is there a way to recover it?
06:19 PM TekniQue: I have a few different workpieces set up in my mill at G54, G55, G56, G57 etc
06:19 PM TekniQue: and I sometimes touch off and reset the wrong coordinate system
06:21 PM toastydeath: not sure, I've never used linuxcnc so i can't really help there
06:25 PM skunkworks: TekniQue, not currently. There was a recent discussion about an undo.. not implimented
06:27 PM CaptHindsight: OOPS button
06:31 PM hazzy: hmm, I guess an "oops" button would be implemented in the UI. It does not seem like it would be very hard, just save the previous parameters when setting the new offsets, and restore them if needed.
06:33 PM hazzy: another thing added to the long list of 'would be nices'
06:34 PM CaptHindsight: GO BACK with settings for how many lines of G-code
06:35 PM hazzy: Run in reverse, or just restart back so many lines?
06:35 PM CaptHindsight: hazzy: https://learnbonds.com/wp-content/uploads/oops-button-ss-.jpg
06:36 PM CaptHindsight: yeah that could cause confusion, GO BACK isn't clear enough
06:37 PM hazzy: Also would be nice to have a whole shop ctrl-z button, undoes any previous action (it should not undo cleaning up though)
06:43 PM Tom_L: TekniQue, keep a backup of your parameters file
06:43 PM Tom_L: then you can recover it
06:45 PM Tom_L: hazzy i could use one for a particular day
06:51 PM sync: hazzy: that is actually an issue, as you cannot do spindle sync motion when unhomed
06:51 PM TekniQue: Tom_L: thanks!
06:51 PM toastydeath: undo causes a lot more crashes than one would think on parameters, so i'd be pretty hesitant to make it easily accessible
06:52 PM toastydeath: i'd love to see a more modern tool offset/fixture offset input method
06:52 PM Tom_L: TekniQue, i think it's the xxxx.var file
06:52 PM Tom_L: yes..
06:54 PM hazzy: sync: Sorry, I am not sure what you are referring to
06:55 PM sync: the undo button
06:58 PM CaptHindsight: would you use a Go Back button for your like if it could send you back 20-30 years only once and when you reach the age you left to jump back you die?
06:58 PM CaptHindsight: like/life
06:58 PM Tom_L: no do overs in life
06:59 PM hazzy: no, I only want to have to make the mistakes once, not twice :)
07:00 PM CaptHindsight: what if you go back and retain the knowledge (or lack of) when you go back?
07:00 PM Tom_L: i want to grow young keeping the knowledge i have
07:01 PM Tom_L: but then i'm not the first to want that
07:01 PM hazzy: hmm, well that makes the decision a little more difficult
07:01 PM CaptHindsight: what if you could only grow younger while losing knowledge (with your choice of knowledge to lose)?
07:02 PM CaptHindsight: say forget how to knit but be 2 years younger
07:02 PM hazzy: That seems about the same as getting old
07:02 PM CaptHindsight: or all Gilligans islands episodes erased from your memory
07:04 PM CaptHindsight: or lets say your brain gets full next year and for every bit of new info you have to lose some
07:04 PM Tom_L: but can you relearn it?
07:05 PM CaptHindsight: as long as it does not take up any new space
07:06 PM Tom_L: no because they came up with a newer compression algorithm and i will apply it
07:14 PM toastydeath: i think it would matter how information is lost
07:15 PM Tom_L: ok, i should go work on the mill.
07:15 PM toastydeath: because i've become better at learning over the years, so if i can choose what I retain, I would be okay with forgetting and relearning
07:18 PM hazzy: toastydeath: I would agree with that, learning how to learn is almost more important than what you learn
07:18 PM toastydeath: so i think i would take that and just remember that i did it at one point, and then forget it and do something else
07:19 PM Tom_L: but you wouldn't know if you did it
07:19 PM toastydeath: i don't think it would matter, just keeping things interesting
07:19 PM toastydeath: or forget how you learned it and just keep the end skill
08:03 PM gregcnc_: dang look at this crazy setup turning on a mill http://www.blackcountrysteam.co.uk/SW586.jpg
08:54 PM * hazzy is supposed to be helping decorate Christmas cookies, but instead he ponders how to implement the equivalent of THC on a CNC cookie frosting machine
08:57 PM jdh: FHC, surely someone has an arduino for that.
09:03 PM hazzy: gregcnc_ wow, that is impressive. Looks like something Wayne Grenning would do ...
