12:26 AM MrHindsight: I give stuff to the Chinese that I want to buy for cheap
12:30 AM MrHindsight: now that cost is going to go up :(
12:37 AM MrHindsight: Putin's M.O. has been destabilize, destabilize, destabilize....
12:38 AM MrHindsight: now you see how it works
01:07 AM Tecan: https://www.youtube.com/watch?v=JDYsk1KQaHk
01:19 AM IchGucksLive: hi all from germany Cloudy
01:23 AM IchGucksLive: morning gloops
01:23 AM IchGucksLive: hioe is the feeling
01:23 AM IchGucksLive: how
01:23 AM gloops: oh i wasnt so disappointed Ichs
01:23 AM gloops: did well to get that far
01:24 AM IchGucksLive: agree
01:24 AM gloops: we had an easy group, easy games to the final - didnt do it
01:24 AM gloops: we havent played anybody yet
01:25 AM gloops: might be a good side next time
01:26 AM IchGucksLive: hope is always around
01:28 AM gloops: maybe Croatia can win the cup
01:31 AM IchGucksLive: gloops, what does this mean Coast to a Stop
01:31 AM IchGucksLive: simpoly run out
01:32 AM gloops: yes, run out of power and stop
01:32 AM gloops: like if the engine cuts out - you coast to a stop - with no power
01:33 AM gloops: or stop pedalling on a bike
01:34 AM IchGucksLive: ok
01:36 AM gloops: possible hurricane heading to europe
01:37 AM IchGucksLive: this will blow out the heat
01:39 AM gloops: probably, could do with some rain though
01:44 AM IchGucksLive: rain is never a fault in summer heat
01:44 AM IchGucksLive: ofcause not on harvestdays
01:48 AM IchGucksLive: does somone know if there is a tracker for china post ID180234++***CN
01:48 AM IchGucksLive: or are this ids only the pay recive
01:48 AM IchGucksLive: as ChinaPost uses UM ID Letters
01:48 AM IchGucksLive: not ID
01:49 AM IchGucksLive: i tray to order from Malasya RR ID
01:49 AM IchGucksLive: this come to germany in 10 DAYS
01:49 AM IchGucksLive: and a real track
01:49 AM IchGucksLive: China guys only say track but there is no real
01:53 AM gloops: lol
01:53 AM gloops: i never had a tracking number from China that worked
01:55 AM IchGucksLive: it is only a shipment number
01:56 AM IchGucksLive: im missing deliverence from 10th Mai
01:56 AM IchGucksLive: will now ask for refund
01:56 AM IchGucksLive: my personal record is 72days
01:57 AM IchGucksLive: from Malaysia non over 12days
01:58 AM gloops: for my screws i asked them for 3 weeks if they had posted - yes yes yes, then they asked me if i wanted the ends machining lol
02:01 AM Deejay: moin
02:02 AM IchGucksLive: ;-)
02:03 AM IchGucksLive: ok im off
02:03 AM IchGucksLive: later
02:52 AM MrHindsight is now known as CaptHindsight
04:46 AM XXCoder: lol on tooli cnc machine
04:46 AM XXCoder: its multitool cnc machine, and they want 7k bucks for it
04:47 AM XXCoder: and its frame is little more fancy than one of chineseium laser frames.
04:47 AM XXCoder: https://www.indiegogo.com/projects/toolig3-robotic-tools-for-artist-and-makers/coming_soon/x/9289429
05:08 AM jthornton: morning
05:19 AM XXCoder: yo
05:19 AM Tom_L: hey
05:19 AM Deejay: heya :)
06:46 AM makerman: hi people
07:01 AM makerman: Does anybody have results of china "Kugelumlaufspindeln" I think the coresponding eng word is threaded rod
07:02 AM makerman: Ball screw is right I think
07:03 AM makerman: I am looking for their tolerances
07:35 AM SpeedEvil: All chinese products are 100% accurate with 0 error.
07:35 AM gregcnc_: built and inspected by people who care
07:35 AM SpeedEvil: More seriously, errors will depend on maker, and consistency of that error will depend on QC.
07:35 AM SpeedEvil: If they don't tell you the errors, they either don't know about them, or don't care.
07:36 AM SpeedEvil: Neither of which is a good place to be in if you want it to be better than 'mostly straight'
07:36 AM SpeedEvil: Contact your vendor at a minium and ask for data and what their QC process is.
07:56 AM miss0r: Speaking of QC. I ordered three rockwel automation servo drives form thailand(Lond story short; that was the only place I could find them). They look like shit
07:57 AM miss0r: They got here today. They are rested up. two of the three servos I am unable to spin by hand. The one that can spin sounds like someone had a go at lubracating it with sand, and the factory connectors are cut off
07:57 AM miss0r: also; they are rusted pretty bad all of them.
07:58 AM miss0r: by all that is holy: I hope the encoder is working on one of them
07:59 AM makerman: The Shop were I buy them is here in Germany and I live in germany so I could send them back. no problem
08:00 AM makerman: So I thought some of you have exp with the "cheaper" ball screws
08:00 AM makerman: I will try them
08:00 AM gregcnc_: what's the deal with VAT and EU ebay sellers, if i buy in the US? they just don't bother taking it off?
08:00 AM miss0r: alot of us has experience with cheap ballscrews
08:00 AM SpeedEvil: miss0r: :(
08:00 AM miss0r: But it can go either way, in my own experience
08:00 AM SpeedEvil: makerman: fundamentally it also depends what you want them for.
08:01 AM SpeedEvil: makerman: If you're using them for imprecise stuff that almost anyone seriously specifying that class of device would require - it'll likely be fine.
08:01 AM miss0r: SpeedEvil: I guess that is to be expected for second hand material ordered from thailand ;) Also, one of them looks like someone took an angle grinder to it at some point
08:01 AM makerman: Tolerance class is T07 I am looking for
08:02 AM miss0r: o_0 what is T07?
08:02 AM gregcnc_: made up china spec?
08:03 AM miss0r: Topdallah07 ? :P
08:04 AM gregcnc_: If accuracy is a real concern buy form a reputable source and pay the price. if anything works, use anyhting
08:05 AM skunkworks: http://electronicsam.com/images/KandT/conversion/xaxis/ballscrew.JPG
08:05 AM skunkworks: I have really small hands.. ;)
08:05 AM miss0r: T07: 52m tolerance over 300mm
08:06 AM miss0r: Acording to Thomson ballscrews ^
08:07 AM miss0r: They are also the 'lowest' acuracy sold by them. They are rolled, not ground. and they specify that they are to be used for linear movement with limit switches, and not precision positioning.
08:07 AM miss0r: Anyway. I'll be back later
08:08 AM skunkworks: If I remember right - there are a few ebay sellers that people like on ebay. (will machine ends too)
08:08 AM skunkworks: *cnczone
08:11 AM gregcnc_: Same as C7. I didn't remember Thomson listing their classes that way.
08:18 AM makerman: Did anybody use the cheap JMC Servo Motors
08:19 AM makerman: they are servos ! not stepper
08:20 AM makerman: What I like about them, they have integrated drivers
08:22 AM gregcnc_: what's wrong with servo?
08:22 AM makerman: I am confused about the datacheet
08:23 AM gregcnc_: which model?
08:25 AM makerman: The problem is
08:25 AM makerman: I expect to have 2 connections to the servo
08:25 AM makerman: 1 VCC
08:26 AM makerman: 2 RS232
08:26 AM makerman: The Datasheet say they are 3 connections
08:27 AM makerman: JMC- iHSV57
08:27 AM makerman: greg u have a shop ?
08:28 AM IchGucksLive: hi all
08:28 AM gregcnc_: shop?
08:28 AM Beachbumpete1: I have not tried one of those integrated driver motors yet but the idea seems appealing for some reason.
08:28 AM makerman: Hallo
08:28 AM IchGucksLive: makerman, im in germany
08:28 AM makerman: I am too :D
08:28 AM Beachbumpete1: Still working on my DMM servo systems lathe LOL
08:28 AM IchGucksLive: Zweibrücken
08:28 AM makerman: ok
08:29 AM IchGucksLive: JMC- iHSV57 ist das der Servvo Driver
08:29 AM makerman: samt motor
08:29 AM makerman: die endstude ist integriert in den motor
08:30 AM IchGucksLive: ich sehs

08:30 AM makerman: kennst du den nicht
08:30 AM makerman: don tu know this server ?
08:31 AM IchGucksLive: makerman, eion klasiches hybrid system
08:32 AM IchGucksLive: da wärst du mit einem konventionellen HSS86 besser drann
08:32 AM IchGucksLive: makerman, FRage zu dem System ansich eine Fräse oder drehbank
08:32 AM makerman: fräse
08:33 AM makerman: HSS86
08:33 AM makerman: ich schau nach
08:33 AM IchGucksLive: makerman, welche Steuerkarte hast du
08:34 AM makerman: Ich bin mir noch nicht ganz sicher was ich zu diesen motoren noch brauche
08:34 AM makerman: muss noch info sammeln
08:34 AM IchGucksLive: also der motor ist auf 36Volt ausgelegt und bringrt nur 2000RPM
08:35 AM IchGucksLive: makerman, Diese Schnittstelle zum PC würde reichen

08:36 AM IchGucksLive: makerman, ich baue ca 100 maschine im jahr
08:37 AM IchGucksLive: makerman, schau mal ob da ein eigenes fewnster mit meinem namen aufgegangen ist
08:38 AM IchGucksLive: makerman, bist du noch da
08:38 AM jesseg: Guten Morgen
08:38 AM IchGucksLive: hi jesseg
08:38 AM jesseg: Howdy :D
08:38 AM IchGucksLive: its getting summer here tomorrow
08:39 AM IchGucksLive: jesseg, he got lost in information
08:40 AM jesseg: IchGucksLive, huh? who got lost in what information?
08:40 AM IchGucksLive: jesseg, first ligt on a newly build https://www.youtube.com/watch?v=bd3UCLH1YuM&feature=youtu.be
08:40 AM IchGucksLive: jesseg, first intro speed at 5m/min
08:41 AM IchGucksLive: 48V 4Nm Timingbelt 20/25 on Ballscrew HGH20
08:41 AM jesseg: IchGucksLive, wow super cool!
08:41 AM IchGucksLive: the complete mashine is 2200 Euro without 4th
08:42 AM IchGucksLive: prices are falling on profile but rising on Eelctronic
08:42 AM jesseg: cool
08:43 AM IchGucksLive: makerman, still online
08:44 AM makerman: ajo
08:44 AM makerman: Ich muss gugge
08:44 AM makerman: Ich bin ninekeier
08:44 AM makerman: is näwwa zw
08:45 AM makerman: ne
08:45 AM makerman: :D
08:45 AM IchGucksLive: makerman, schau mal ob da ein fenster / querry mit meinem namen offen ist
08:56 AM IchGucksLive: hi hsd
08:56 AM IchGucksLive: jesseg, im off till later
09:31 AM Beachbumpete1: any of you guys have one of those creality 3d printers?
09:32 AM rebecca: nope
09:32 AM Beachbumpete1: or girls LOL
09:32 AM rebecca: recently got an anycubic i3 mega though
09:32 AM Beachbumpete1: how ya like it? what is the envelope on it and what price?
09:33 AM rebecca: love it. produces really nice quality output if you dial in the settings right. also wonderful build plate surface
09:34 AM rebecca: 210x210x205 iirc
09:34 AM rebecca: 336USD
09:34 AM Beachbumpete1: nice
09:35 AM rebecca: not including shipping
09:35 AM Beachbumpete1: the Creality CR10 is like 300x400 or so I think
09:35 AM rebecca: okay. thinking of getting one?
09:35 AM Beachbumpete1: not sure yet but I want a decent one that has some volume of area
09:35 AM Beachbumpete1: that one you have actually looks pretty sweet\
09:36 AM rebecca: i think the build vol on mine is adequate for me. i'm running a print now which has room to spare and will run over 10hours
09:36 AM rebecca: not sure i have the patience for bigger :D
09:38 AM rebecca: what do you plan to use it for?
09:47 AM gloops: welcome president Trump!
10:09 AM Beachbumpete1: not sure just yet but I have been wanting one to learn on and if I am going to get one I want it to have a usable volume area so as not to be too restricted to size per dollar I spend...
10:41 AM Joe_Hildreth: Hello all, I have a parallel port question. I have added a second parallel port to a machine via a pci card. The OS did create a /dev/lp1 for this card. On the stepper config wizard where it states you can use either the port address or Linux port number it is referring to the lp# in the /dev, correct?
10:41 AM Joe_Hildreth: is it better to use the address or the port number, or does it matter?
10:42 AM jesseg: hrm my guess is you'd probably be just fine addressing it by the port number
10:42 AM jesseg: since it's different hardware brand and bus and whatnot, they should always enumerate in the same order
10:42 AM Joe_Hildreth: I belive the address of the new card is at 0x1100. I got the with a cat /proc/ioports | grep parport
10:43 AM jesseg: or -- I guess I should ask, are both parallel ports the same type of expansion card?
10:43 AM jesseg: or is one onboard and one's pcie?
10:43 AM Joe_Hildreth: The first port is onboard 0x378
10:44 AM Joe_Hildreth: The second PCI
10:44 AM jesseg: ok they almost certainly will always enumerate in the same order, although if you re-install OS you might want to double check to make sure they are still enumerating in same order
10:45 AM Joe_Hildreth: Would using the port address be a safer bet? Would the address of the PCI port change on a new install or differnt PCI slot?
10:47 AM jesseg: you know I really don't know. PCI has a significant additional automagic complexity as compared to ISA, so I really don't know what the rules of engagement are for addresses for printer ports on PCI lol
10:47 AM jesseg: THe old ISA printer ports had jumpers on them and you set the address they answered on. No way that could get changed by the OS LOL
10:48 AM Joe_Hildreth: So the best advice to give a newbie would be to check the hardware any time a slot is changed, hardware added or a new OS install? That would be the conservative advice to give, would you agree.
10:49 AM Joe_Hildreth: I am still working on my next installment of the CNC hobbyist videos.
10:50 AM Joe_Hildreth: jesseg, thanks for the help. You guys make this project of mine go a little easier and I appreciate that!
10:50 AM jesseg: Joe_Hildreth, yes I agree that's a great way to put it
10:50 AM jesseg: most welcome!
10:52 AM Joe_Hildreth: Just wondering, if I were to remove the card and start the machine up, will the OS remove the /dev/lp1 from the list?
10:52 AM jesseg: probably, assuming it added it.
10:52 AM jesseg: In the old days, we (or the OS installer script) had to create each file in /dev
10:53 AM jesseg: but for the last few years they've been using automatic /dev/ file creation - so the files get created when the hardware is detected and removed when its not
10:53 AM jesseg: so like even plugging in a mouse or a USB web cam or whatever will create a new device in /dev/ then when unplugged it'll disappear
10:55 AM Joe_Hildreth: Interesting, going to go pull the card and verify. brb
10:57 AM Tecan: https://github.com/tecan/GCODE-Tools/tree/master/GCODE-Pro i'll be putting more in here later
10:59 AM Joe_Hildreth: OK, I removed the card and booted the machine. The /dev/lp1 enumeration is gone, so you are correct. The machine only has one PCI slot so I cannot check to see if the port address changes on a different slot.
11:03 AM Joe_Hildreth: After talking to Andy P. and doing some test, I am convinced that the data for pin 14 in in the table listed here: http://linuxcnc.org/docs/2.7/html/hal/parallel-port.html is incorrect for the "IN" column. It is listed as being an input pin in this mode but should be output. On installing a second port and running stepper wizard and setting the port to "IN" it shows this pin as being an output.
11:04 AM Joe_Hildreth: This makes sense because pins 1, 14, 16 and 17 all belong to the same control group. So for modes "in" and "out" they are set to output, and mode "x" the are set to be inputs.
11:04 AM Joe_Hildreth: Now if someone would fix the docs. :-)
11:14 AM flyback: https://www.youtube.com/watch?v=ZBkHRY6fhA8 <---_ HAHAHAAAHHAAHAHAHA nsfw
11:22 AM IchGucksLive: hi all
11:23 AM IchGucksLive: makerman, bist du noch da
11:25 AM IchGucksLive: Joe_Hildreth, linux is able to drive 4 paralell ports
11:26 AM IchGucksLive: gloops, 5Mio Pound for tomorrows Golf tour
11:26 AM IchGucksLive: gloops, UK must have no problems on that
11:26 AM IchGucksLive: gloops, kay burly live at the scene
11:27 AM Joe_Hildreth: IchGucksLive, the Parallel Port Driver docs says that it can drive up to 8 ports
11:27 AM IchGucksLive: LCNC can do so
11:27 AM Joe_Hildreth: defined by MAX_PORTS in hal_parport.c
11:28 AM IchGucksLive: as you will not find a pc with more then 4 pci socket
11:28 AM IchGucksLive: Joe_Hildreth, but more efficient will be using a mesa
11:29 AM Joe_Hildreth: Well, that is true. I have never noticed more than that. I agree using mesa would be better for lots of IO
11:29 AM IchGucksLive: 12 Servos at 4mio steps per second RT
11:29 AM pcw_home: you could drive 4 dual parallel port cards
11:30 AM IchGucksLive: in this modern times it will come up again as M4 does not work proper on W10
11:30 AM IchGucksLive: but the ground Base is set by arduino now
11:30 AM Joe_Hildreth: You have a point pcw_home. I guess if the cards are cheaper than buying the mesa cards, but at some point it would be diminishing returns wouldn't it?
11:31 AM IchGucksLive: Joe_Hildreth, 20USD per card
11:31 AM IchGucksLive: Joe_Hildreth, but max 200k
11:31 AM Joe_Hildreth: for dual PP cards?
11:32 AM IchGucksLive: yes
11:32 AM Simonious_: I've been using fusion 360 for g-code, is it possible to 'platter' - that is if I'm cutting a sign can it 'best fit' 10s of objects onto my medium?
11:33 AM IchGucksLive: Simonious_, you can use a simple offset at the end
11:33 AM IchGucksLive: G92
11:33 AM Simonious_: and that'll autofit a bunch of letters to cut out into best use of material? doesn't sound right
11:34 AM cpresser: so you want nesting?
11:34 AM Simonious_: sure, yes, that keyword makes as much sense as platter. yes
11:34 AM IchGucksLive: Simonious_, look at the free Sheetcam option
11:35 AM * cpresser is a non native speaker, had to look up 'platter'
11:35 AM IchGucksLive: Joe_Hildreth, DELOCK 89016
11:35 AM IchGucksLive: Joe_Hildreth, https://www.ebay.de/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=DELOCK+89016&_sacat=0
11:36 AM cpresser: afaik, fusion only allows manually alignment of items
11:36 AM Tom_L: array or grid pattern
11:36 AM IchGucksLive: Simonious_, do you got a dxf of it
11:36 AM cpresser: vcarve-pro has a nesting tool: https://docs.vectric.com/docs/V9.0/VCarvePro/ENU/Help/Drawing/Nest%20Parts/Nest%20Parts.html
11:36 AM Simonious_: IchGucksLive: I can have.. at the moment this is more of a hypothetical question, why?
11:36 AM IchGucksLive: even Freecad coudt do this
11:37 AM Simonious_: cpresser: we are considering vcarve
11:37 AM IchGucksLive: Simonious_, to generate your code
11:38 AM IchGucksLive: Simonious_, http://heimwerkermarkt-tretter.de/hs_2.jpg
11:38 AM Tom_L: that's great until you want the wood grain the same direction :_
11:38 AM IchGucksLive: Simonious_, this is my letter milling
11:38 AM Simonious_: IchGucksLive: very nice :) I've done a few myself, however in this case I'm cutting out letters and want to nest them tightly
11:39 AM IchGucksLive: sheetcam will optimize the pattern
11:39 AM IchGucksLive: there are more wood signes http://heimwerkermarkt-tretter.de/hs.jpg
11:39 AM Joe_Hildreth: IchGucksLive, thise are pretty affordable, but let us pretend we have 8 ports in the machine. That would give 136 IO pins to use. The smaller Mesa cards if I recall drive 5 stepper axis with hardware step generator and 72 IO pins. Twice the cost though compared to the dual PP cards. Would be an interesting experiment nonetheless.
11:40 AM IchGucksLive: Joe_Hildreth, but 200k you wont reatch VERSES 4Mhz you can
11:41 AM IchGucksLive: Joe_Hildreth, 72 IO is a hell of pins
11:41 AM Tom_L: 72 for 60 bux
11:42 AM Tom_L: less than a dollar an io :D
11:42 AM Joe_Hildreth: You mean data throughput. Oh I agree with you. If lots of IO and data throughput are important then I would avoid PP and go mesa
11:43 AM IchGucksLive: Tom_L, its 102 for 60 and 136 at 80
11:43 AM Joe_Hildreth: You are correct Tom_L. I think as the series of tutorials progress, I will get some mesa boards and cover them the best I can. I have loads of things I hope to cover as time goes by.
11:43 AM IchGucksLive: makerman, ich bin am warten
11:43 AM Tom_L: 7i90
11:44 AM Tom_L: 72 for 60
11:45 AM gloops: v-carve has 'nest selected objects' function
11:45 AM Tom_L: IchGucksLive what card has 136?
11:45 AM IchGucksLive: 3x double parport at 18USD at 17pin etch
11:46 AM Tom_L: ahh, slow
11:46 AM IchGucksLive: 136 are 4x2x17
11:46 AM IchGucksLive: Tom_L, as i tryed to told him cost verses speed
11:47 AM Tom_L: i'm not sure what would ever need 136 io anyway
11:47 AM IchGucksLive: AS the RULE is COST vs Torque vs Speed vs Precision
11:48 AM Tom_L: pay your money.. how fast do you want to go
11:48 AM gloops: im surprised inkscape doesnt have this kind of nesting feature, a lot of people use it for laser
11:48 AM IchGucksLive: gloops, for image
11:49 AM gloops: well you could still arrange the vectors in inkscape before sending them to CAM
11:49 AM IchGucksLive: gloops, arent you invited to the trump dinner
11:49 AM IchGucksLive: gloops, a person like you
11:49 AM gloops: no only VIPs
11:50 AM gloops: im a UIP
11:50 AM IchGucksLive: gloops, so you do not go to the golfclub
11:50 AM gloops: no ive never played golf
11:50 AM IchGucksLive: you do not need that but there is the moey for good cnc routers
11:52 AM gloops: at the golf club?
11:52 AM Joe_Hildreth: I hope I didn't give the impression that this is what I was wanting to do. I am just working on my outline for my next CNC for the Home Hobbyist video and I am covering the parallel port. My real questions were about using the enumerated ports verse using the IO address in the setup.
11:53 AM Tom_L: gloops, there's a printed golf club http://tom-itx.no-ip.biz:81/~webpage/cnc/temp/prints/Ti_print1.jpg
11:53 AM Joe_Hildreth: And about what seems to be an error in the PP driver docs for pin 14 on the "IN" column. Sorry for the confusion.
11:53 AM Tom_L: Ti
11:53 AM Tom_L: with composite stem
11:54 AM gloops: looks metal Tom_L?
11:54 AM Tom_L: Ti
11:54 AM gloops: 'golf, the best way to ruin a good walk' Winston Churchill
11:54 AM Tom_L: the handle is composite
11:54 AM IchGucksLive: Joe_Hildreth, pin 14 is most use out at EPP
11:54 AM IchGucksLive: Joe_Hildreth, the ECP centronics is treestate so itcan be in
11:55 AM Tom_L: tri state
11:55 AM IchGucksLive: ;-)
11:56 AM IchGucksLive: Joe_Hildreth, but then you need to get your own BOB as no industrial suports this after 1992
11:56 AM IchGucksLive: IBM Rule 15
11:56 AM Joe_Hildreth: But aren't pins 1, 14, 16 and 17 all part of the control group? They all would be set as either IN or OUT not individually right? When setting a port to "IN" with step wizard, it shows pin 14 as output. In the docs is shows it as input.
11:57 AM Joe_Hildreth: IBM Rule 15???
11:58 AM IchGucksLive: Joe_Hildreth, as tome said this group is Tri State but in comen days only used as output as DB1205
11:58 AM IchGucksLive: 12 out 5 in
11:58 AM IchGucksLive: you can go 8 out and 9 in
11:59 AM IchGucksLive: if you configure the port as IN
11:59 AM IchGucksLive: then set it to ECP
11:59 AM IchGucksLive: and get your own BOB onto it
11:59 AM Tom_L: what's Bob got to do with it???
11:59 AM IchGucksLive: Remember 600 uA 3,3V
12:00 PM Tom_L: he's just a by-stander
12:00 PM skunkworks: he prefers robert...
12:00 PM IchGucksLive: Tom_L, no direct connect to the parport only via HCT
12:00 PM Joe_Hildreth: According to the table, when set as in, you have 14 pins in and 3 pins out.
12:01 PM IchGucksLive: Joe_Hildreth, DATA pins are oinly out
12:01 PM IchGucksLive: so 17 total - out is max in
12:02 PM IchGucksLive: 17 sub 8 =9
12:02 PM Tom_L: since when?
12:03 PM IchGucksLive: aristoteles i guess
12:03 PM Joe_Hildreth: I am getting confused. See table 1 on this page, http://linuxcnc.org/docs/2.7/html/hal/parallel-port.html This is what I am referring to.
12:05 PM IchGucksLive: Joe_Hildreth, there is a X colum i refer to
12:07 PM IchGucksLive: Joe_Hildreth, you can get SPP EPP and 1284 Comen EPP
12:07 PM IchGucksLive: sorry
12:07 PM IchGucksLive: SPP ECP and EPP=1284
12:08 PM IchGucksLive: this is the parport definision
12:08 PM IchGucksLive: and the table showes the pin setting to the 3 STATE
12:08 PM Joe_Hildreth: I understand that, my question is about pin 14 on the in column. For "in" it would seem that the data pins are set to in, the status pins are set to in and the control pins set to out, except, pin 14 is labelled as in. I would think that the control pins would all be set at the same direction.
12:09 PM Joe_Hildreth: I will go read the IEEE 1284 specs. maybe that will help me out. :-)
12:10 PM IchGucksLive: Joe_Hildreth, only tzhe real PRO freeks will go for that and need to hardsearch for hardware
12:11 PM IchGucksLive: the international around 15000 CNC a week is 1205
12:13 PM IchGucksLive: even arduino cnc follows this standard
12:13 PM IchGucksLive: as they coudt improve it easy
12:14 PM IchGucksLive: 1515 woudt improve all the cnc stuff
12:14 PM IchGucksLive: on a 30cpc connector
12:15 PM IchGucksLive: or just clamp of
12:16 PM IchGucksLive: IF MAKERMAN comes in tell him im here at 7pm Berlin time every day

04:16 PM tjb1: I found some problems with the logic, it stops sending outputs below 100v so I don't know if I'm just going to lower the floor or do something like target +- 50v for response
04:17 PM tjb1: or just always output a signal and let the computer decide when to act
04:19 PM JT-Shop: you made the bigger green board?

04:22 PM JT-Shop: yea I have one like that on my hot glue machine
04:23 PM tjb1: it has sd card slot that I never hooked up...i dont know what id use it for
04:23 PM tjb1: I would have to monitor voltage and then do writes when voltage dropped to not interfere with loop time during reading
04:24 PM JT-Shop: you can run a file from the display
04:26 PM tjb1: on your hot glue machine?

08:51 PM Tom_L: ok i got a water cooled spindle today :)
08:51 PM hazzy-lab: nice!
08:51 PM `Wolf: ooo
08:51 PM Tom_L: wanna see?
08:51 PM hazzy-lab: of course!
08:51 PM hazzy-lab: :)
08:52 PM * Tom_L snickers a bit
08:52 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/spindle_cooler/Cooler5.jpg
08:52 PM `Wolf: I got that HB04 wireless pendant in today, looks pretty nice
08:52 PM `Wolf: lol
08:52 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/spindle_cooler/Cooler1.jpg
08:53 PM Tom_L: pipe is just a bit smaller than the motor od
08:53 PM Tom_L: fits snug on the motor
08:53 PM hazzy-lab: lol
08:53 PM `Wolf: needs active cooling, recycle a dehumidifier =P
08:53 PM Tom_L: it will help until i can find a real one :D
08:53 PM Tom_L: o
08:53 PM `Wolf: thats what I am planning on using for co2 laser
08:53 PM Tom_L: i'll just fill the bucket with ice
08:54 PM hazzy-lab: Put some thermal past and it'll be perfect
08:54 PM CaptHindsight: https://youtu.be/4if9RUkWKmI?t=39s
08:54 PM Tom_L: i thought about that hazzy-dev
08:54 PM Tom_L: that tube full o water trick works like a treat too btw
08:55 PM hazzy-lab: antiseize is a excellent thermal conductor, and cheap
08:55 PM `Wolf: $5 ink bird thermal control unit SSR, pump and mini radiator + dehumidifier, seeing that its just a compressor/evaporator
08:55 PM hazzy-lab: but it be a mess
08:55 PM `Wolf: does that spindle motor really need that much cooling?
08:56 PM Tom_L: it gets damn hot
08:56 PM CaptHindsight: won't hurt nothin to cool it
08:56 PM Tom_L: but will it help any?
08:56 PM hazzy-lab: Take the compressor out of a dorm fridge and run the coil directly around the motor would also work, not overkill at all :D
08:56 PM Tom_L: i had all the stuff so i figured i'd try it
08:56 PM Tom_L: pump left over from fishtank days
08:58 PM Tom_L: all i need now is more tubing so i can put the bucket on the floor
08:58 PM `Wolf: hazzy-lab: same thing as the dehumidifier, could use a window ac unit as a donor as well, only problem is keeping the motor above rooms dew point
09:00 PM hazzy-lab: `Wolf: thats true, but the coil on the fridge does not have any fins on it, so you might be able to wrap it around the motor, and not have to even recharge the system
09:01 PM `Wolf: you know, I’ve never taken one of those apart, I didn’t know that lol
09:01 PM Tom_L: it would be hard to recoil it without getting a kink somewhere
09:01 PM Tom_L: since it's attached on both ends
09:01 PM `Wolf: I was thinking http://a.co/1YZ2ddM and a 120mm fan
09:02 PM Tom_L: or a heater core from a salvage yard
09:02 PM hazzy-lab: That's darned cute!
09:02 PM `Wolf: just cool the bucket of water with 1 pump and 2nd pump to motor/co2 tube being cooled
09:04 PM `Wolf: Tom_L: same idea, except that one already has 120mm fan mount tabs and my local salvage yard probably charges just as much for a heater core lol
09:04 PM Tom_L: true
09:04 PM Tom_L: that one is plenty cheap enough
09:04 PM `Wolf: use the temp control unit to hold the bucket at just above dew point
09:05 PM `Wolf: I think the total was going to be under $80 in parts
09:06 PM Tom_L: i'm not sure i've posted a pic of the mill in it's completed state
09:06 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/spindle_cooler/Mill1.jpg
09:06 PM `Wolf: vs $500 for a co2 laser water chiller
09:06 PM Tom_L: except it's got the shars vise on it now
09:06 PM `Wolf: looks good
09:06 PM `Wolf: mine is a spread of parts again
09:07 PM Tom_L: i've got several shapes of plastic for the front depending if the vise is on or not
09:07 PM Tom_L: and an extension that sits on top of the screwed on pieces
09:07 PM Tom_L: minimizes the mess
09:07 PM `Wolf: I decided to install oiling system to my mill build
09:08 PM Tom_L: i should but i can get to all the stuff on mine fairly easy
09:08 PM `Wolf: https://i.imgur.com/Bfyg7gw.jpg https://i.imgur.com/ukSiCKE.jpg
09:08 PM `Wolf: I can’t lol
09:08 PM `Wolf: this X2 is stuffed
09:09 PM `Wolf: I’m not partly stalled waiting on the fitting for the X ball nut
09:09 PM `Wolf: s/not/now
09:10 PM Tom_L: why's the side plugged with the bolt?
09:10 PM `Wolf: thats the oiling hole
09:10 PM Tom_L: right
09:10 PM `Wolf: fitting is 6-10 days out, had to order a odd ball fitting
09:11 PM `Wolf: https://i.imgur.com/Mdtl5L6.jpg tight work space lol
09:12 PM Tom_L: should be solid when it's done
09:12 PM Tom_L: i can tell you my steppers have more than enough torque
09:13 PM `Wolf: I have 420oz should be overkill
09:13 PM Tom_L: 570
09:13 PM `Wolf: haha yeah should be good to run a cutter with the spindle off
09:13 PM Tom_L: i was test running this new program and had something on the table in the way and the Y table came up against it and it just started pushing the mill instead of stalling
09:14 PM Tom_L: that's running them at half power
09:14 PM Tom_L: 2.5A instead of 5
09:14 PM Tom_L: err X axis i meant
09:14 PM `Wolf: my x1 snapped a 3/8 end mill in half w/ 420oz motors
09:14 PM `Wolf: no stall or pause
09:15 PM Tom_L: yeah
09:15 PM Tom_L: i'm pretty happy about that
09:15 PM `Wolf: my only worry is the Z
09:15 PM Tom_L: i doubt i'd need the 3:1 reduction on Z at all
09:15 PM `Wolf: I have mine planned with 1:1
09:15 PM Tom_L: i had a counterweight on the sherline but the steppers were 280? in oz iirc
09:16 PM `Wolf: but have a cable counterweight
09:16 PM Tom_L: should be fine i bet
09:16 PM `Wolf: gas strut setup hidden in the column
09:16 PM Tom_L: i got a 3:1 and 2:1 pulley set but started with the 3:1
09:17 PM Tom_L: i could probably slap a 5hp motor on the spindle without worrying about stalling z :)
09:17 PM `Wolf: overkill is never a bad thing lol
09:17 PM Tom_L: do'overs isn't an option really for me
09:18 PM Tom_L: i built the electronics on the sherline with that in mind and just moved it all over when the mill was ready
09:18 PM `Wolf: buddy of mine stopped over to pick up a part I made him, in turn getting a 3.25” bar stock 7’ long so I can make a riser for the x2 column
09:19 PM Tom_L: i had one of those for the sherline but never used it
09:19 PM `Wolf: of course the riser means that my Z ball screw might be short now =/
09:20 PM Tom_L: cad cam says this program'll take 2.5 hrs on the first side
09:21 PM Tom_L: side 2 should be a breeze, it's just the profile
09:21 PM Tom_L: and a couple bolt recesses
09:25 PM `Wolf: sweet, I can’t wait to have this X2 making chips
09:26 PM `Wolf: tho the manual mill is starting to feel like it really needs a power drawbar
09:38 PM `Wolf: …https://www.ebay.com/itm/1-4-20-CLAMP-SET-FOR-MACHINIST-TOOL-ROOM-OR-HOBBY-SET-OF-TWO-WITH-HARDWARE/301913077664 seems steep price for aluminum strap clamps…
10:05 PM Tom_L: make your own
10:06 PM `Wolf: i am
10:06 PM `Wolf: $6 of stock = dozen
10:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Strap_clamp.jpg
10:07 PM Tom_L: i made a few from 1/4" steel
10:07 PM Tom_L: no finished pics though
10:08 PM `Wolf: I got 4 feet of 3/4” x 3/8” 6061
10:08 PM `Wolf: doing the tapping step right now
10:08 PM Tom_L: i picked up some 6061 today
10:09 PM Tom_L: 7/8 x 3 x .......
10:09 PM Tom_L: several pieces
10:10 PM Tom_L: hmm i need to cut thos down, maybe i should keep the cutoff for clamps..
10:11 PM Tom_L: i seem to have enough right now though
10:11 PM `Wolf: guess I need to RTFM for the tapmatic lol
10:12 PM Tom_L: those are pretty easy
10:12 PM `Wolf: really just need to set the clutch
10:31 PM `Wolf: damn that thing is easy
10:31 PM `Wolf: though it doesn’t like it if the clutch is set too loose lol
