12:33 AM Crom: PMW is 5v 0-10v is derived from pwm
12:35 AM Crom: 5v = 0 rpm, 0v=maxrpm
12:35 AM Crom: err 10v=0rpm 0=maxrpm
12:35 AM Crom: on the 0-10v
12:35 AM Crom: I use a resistor bridge to get 5v-0v off that
12:35 AM Crom: just because it was easier to get to the screws
12:35 AM Wolf_: on the cheap BOB?
12:35 AM Crom: this one http://www.ebay.com/itm/5-Axis-CNC-Interface-Adapter-Breakout-Board-For-Stepper-Motor-Driver-Mach3-w-USB-/181933891138?hash=item2a5c1ade42:g:ZdoAAOSwhcJWL9rS
12:35 AM Wolf_: I somehow didn’t think they do a 0-10v spindle control out
12:36 AM Crom: you have to feed in on the left side 2 middle screws your stepper voltage which for me is 32v
12:37 AM Crom: left 2 screws closed to you is relay, further 2 is 0-10v
12:37 AM Wolf_: yeah, I have one of those breakouts here, says 12-24v in
12:37 AM Crom: lemme go measure mine I though it was 32v
12:37 AM Wolf_: so that is tied to pin1 ?
12:38 AM Wolf_: all the way through the optocoupler isolated 0-10V analog voltage output can be controlled with the corresponding analog interface converter to control the spindle speed. Output port P1 port.
12:38 AM Wolf_: I guess so
12:39 AM Crom: mines just measured 27v
12:39 AM Wolf_: hmm, guess I need to play with that on my mini mill
12:40 AM Wolf_: and with my BLDC sewing machine motor controller
12:42 AM Crom: Im using the normally open hall effect and induction sensor for X and Y... I have a 2n2222 transistor between gnd and pin 15 for x and gnd and pin 11 for y. the sensor black wire going thru a 4700ohm resistor to the base of the transistor. gnd of the sensor with the gnd of bob next to pin15
12:43 AM Crom: there's a thought.... using a consew CSM1001 servo for a spindle speed control
12:46 AM Crom: its a 4k rpm motor with PID and it's 3/4 hp
12:46 AM Wolf_: http://i.imgur.com/v68lNrg.jpg mine is a 750W
12:46 AM Crom: same one I have
12:46 AM Crom: with needle positioner... It's on my Juki DL5550
12:46 AM Crom: best $200 I ever spent!
12:46 AM Wolf_: lol, I got mine just for the X2 build http://i.imgur.com/jBjaRyg.jpg
12:47 AM Crom: cylinder top right for tool changer/
12:47 AM Crom: ?
12:47 AM Wolf_: yeah, 4” air cylinder w/ 3/4” travel
12:48 AM Crom: going like tormach and using the cupped spring washers?
12:48 AM Wolf_: http://i.imgur.com/OeR3fzr.jpg I need to redo the whole thing
12:49 AM Wolf_: need to put the cylinder on a floating plate so it presses just the top nut and drawbar
12:51 AM Crom: tormach does something like that...when the cylinder actuates it pulls tight the plate under the spindle bearing preload nut flange and pushes down on the drawbar compressing the cup spring washers
12:52 AM Wolf_: yup
12:52 AM Crom: so you're not putting extra load on the bearings
12:52 AM Wolf_: I got yelled at for top loading the spindle bearing like it does currently
12:53 AM Wolf_: some day I’ll get that machine done lol
12:54 AM Crom: if you make a new spindle pretension nut with a cupped portion and a flange you can hide the cupped washers in
12:54 AM Crom: and give you the flange to pull against
12:55 AM Wolf_: that or just turn the current one down some and add a flange to it
12:56 AM Wolf_: I suck at threading (crap lathe) and internal thread sounds no much fun
12:56 AM Crom: if you put a plate across the bottom of the cylinder to retract the nose, you could run it as a single acting piston. have some springs to retract it
12:57 AM Wolf_: I like the double acting :)
12:57 AM Crom: make an arbor to screw the nut you have onto and weld a hunk of steel to it then turn turn it
12:58 AM Crom: I like KISS
12:58 AM Crom: I'm well schooled in murphy and ruperts corollary
12:59 AM Wolf_: the valve I use is a single throw, so the return stays under pressure
12:59 AM Crom: if anything could go wrong it will, and if it should go wrong it won't
01:00 AM Crom: which lathe is that/
01:00 AM Wolf_: 7x10 harbor junk
01:00 AM Wolf_: bought that and my x1 mill used off CL
01:00 AM Crom: heh I see you also have the fleabay Noga not clone indicator arm
01:01 AM Wolf_: the little red one?
01:01 AM Crom: I have mine on my sewing machine right now for seam allowances
01:01 AM Crom: yep
01:01 AM Wolf_: yeah, there is a real noga sitting on the lathe as well lol
01:02 AM Wolf_: fake one makes a good 3rd hand http://i.imgur.com/osOM4DE.jpg lol
01:03 AM Crom: I need to make a new control box... so I can spread crap out so I can get to screws and plugs
01:04 AM Crom: How do you like that yellow sensor and is it hall effect or induction?
01:04 AM Wolf_: http://i.imgur.com/l7KoMTm.jpg I used a scrapped ambulance drawer tray
01:04 AM Wolf_: inductive, I have one mounted on my x1 X axis
01:05 AM Wolf_: seems to work sorta ok, did have a issue with chips piling up in front of it tho
01:08 AM Crom: Im using there http://www.ebay.com/itm/LJ12A3-4-Z-BY-Inductive-Proximity-Sensor-Switch-NPN-DC6-36V-3D-Printer-CNC-Hot-/292041103587 and http://www.ebay.com/itm/HOT-Hall-Effect-Sensor-Proximity-Switch-NPN-3-wires-Normally-Open-With-Magnet-/381643693425
01:09 AM Crom: The 3040 will never do ferrous so hall effect is ok
01:09 AM Crom: X is hall effect and Y is inductive
01:09 AM Wolf_: yeah, same sorta thing, but mine are flat mount, I just use a shcs in a slot to adjust the endpoint
01:10 AM Crom: I move my sensor in or out
01:10 AM Wolf_: but on my X axis its working at min/max/home
01:11 AM Wolf_: at/as
01:12 AM Wolf_: http://i.imgur.com/WUrLcnK.jpg can see it in this pic
01:12 AM Crom: hmmm I could rig something like that on Y... put the sensor on the gantry and I have a "T" slot underneath the table I could use to have moveable blocks to get read my the sensor
01:13 AM Wolf_: under the vice, turned out to be a bad idea because the chips pile up on the ledge
01:14 AM Crom: have an arm which holds the sensor under the lip
01:14 AM Crom: the screws are your induction points?
01:14 AM Wolf_: x2 build I’m mounting it under the table and use a flat bar to hold the trigger points
01:15 AM Wolf_: yeah
01:15 AM Crom: I see the slots now
01:16 AM Crom: I need to raise my 3040 so I can get more room to play under the table.
01:17 AM Wolf_: funny part is the X2 build started as just buying the extended X/Y kit from LMS for the X1 mill lol
01:17 AM Crom: broke a chinesium 1/16" drill bit tonight trying to mount a NO switch for Z home... so I'll have a hall effect, an induction, and a switch for homes
01:20 AM Crom: on the spindle mount I'll mount a piece of angle AL 30mmx30mmx3mm with slots that I can adjust up and down as required
01:21 AM Wolf_: my favorite “I might need a bigger mill” pic http://i.imgur.com/kYDtEtW.jpg
01:21 AM Crom: tomorrow I think Ill have some money.. I need to pay my $60 for the BarZ summer Bash
01:22 AM Wolf_: …if I was closer
01:22 AM Crom: milling the X2 base in the X1 classic!
01:23 AM Crom: those are some honking HUGH steppers 425ozin?
01:23 AM Wolf_: yup
01:24 AM Crom: never lose a step because they are so damn powerful?
01:24 AM Wolf_: that X1 is getting downgraded when the x2 is done lol
01:24 AM Wolf_: hell, didn’t lose a step when I crashed a 3/8 end mill in to a work piece
01:25 AM Wolf_: snapped the end mill and kept going
01:25 AM Crom: I changed the stepper on my Y from a stock 3040 stepper (maybe 45ozin) toa 120ozin I think
01:26 AM Crom: I need to find somemore bigger NEMA 23's
01:27 AM Wolf_: I’ve done worse, back in 07 I bought servo motors off ebay w/ no idea what I was doing for a 2’x2’ router build that never happened, turns out they are BLDC 190v 470w
01:29 AM Wolf_: http://i.imgur.com/rMK9yC1.jpg now I just need a bridgeport to convert lol
01:30 AM Crom: laminations went from .7 to 1.3" betweeb the 2 motors
01:31 AM Crom: how the hell do you drive them?
01:32 AM Wolf_: I don’t have a pic of the latest servo motor I picked up, nema 34 H-348 running at 150v its 745oz/in cont, 1350oz at peak stall
01:33 AM Crom: I am so going to the JMC-motor.com nema23 integrated hybrid closed loop steppers less than $100 for 2nm 248ozin
01:34 AM Wolf_: driving them is easy, http://i.imgur.com/EOp8e4l.jpg 25A 200v servo amp
01:34 AM Crom: I loose the drivers... just run step dir 5v and +-36v dc for the go
01:34 AM Crom: how much is that stack?
01:34 AM Wolf_: but also means I need to go with a mesa 7i77
01:35 AM Wolf_: IIRC I think i got the 3 motors for <$100
01:35 AM Wolf_: servo amps have been around $60 average for the 5 of them I have
01:36 AM Crom: http://jmc-motor.com/products.php?cid=248&id=118
01:36 AM Wolf_: monster motor was $90 shipped, got that one last month
01:37 AM Crom: not a bad price... With the jmc's it's still step and dir at least...
01:37 AM Wolf_: http://www.ebay.com/itm/361313648739
01:39 AM Wolf_: fun part is if needed I can run the sewing machine motor off the same servo amps
01:39 AM Crom: sheeshz that's huge! NEMA what/
01:40 AM Wolf_: 34
01:40 AM Crom: careful, you don't want to flip the earth...
01:41 AM Crom: how many RPM with that go to?
01:41 AM Wolf_: well, figured I might need some grunt for a Z axis on a knee mill :)
01:41 AM Wolf_: 1800
01:41 AM Wolf_: 1850rpm on the 1350oz/in beast
01:41 AM Crom: yeah... at what feedrate? sheeshz
01:42 AM Crom: gear it up and run my lathe better than my 1/2 horse GE motor
01:44 AM Wolf_: lol yeah, its a 1.1hp 821W on the 348-H motor, the other ones I have are 342-H, 290oz/in peak stall, 470W 6000rpm motors
01:44 AM Crom: I need a new lathe and figure out to rebuild my plain bearings
01:44 AM Crom: s/and/or/
01:46 AM Crom: oh it's bed time... nite nite
01:46 AM Wolf_: I hate ebay sometimes, order shit from the USA and china, stuff from china says its going to be here 2 days after the stuff from USA...
01:46 AM MacGalempsy: evening folks
01:47 AM Wolf_: whats up Mac
01:48 AM MacGalempsy: not much. they are pulling out of the hole, so just chilling and watching gt car racing
01:49 AM MacGalempsy: what are you doing Wolf_?
01:50 AM Wolf_: getting ready to go sleep lol
01:50 AM Wolf_: and wishing parts that are dragging ass across the country would move faster
01:52 AM MacGalempsy: lol.
01:52 AM Wolf_: surprisingly my 2.5W laser showed up today
01:52 AM MacGalempsy: instant gratification ends when you click buy
01:52 AM Wolf_: 7 days from china isn’t bad lol
01:53 AM MacGalempsy: thats really good
01:53 AM MacGalempsy: dhl?
01:53 AM Wolf_: they gave me the wrong tracking number on aliexpress tho
01:53 AM Wolf_: yeah it was dhl
01:54 AM Wolf_: if I was evil I would wait another week, then ask where my order is lol
01:54 AM MacGalempsy: i bought an arduino w ramps on there before and it showed up i 2 or 3 days
01:55 AM MacGalempsy: i tracked it at like 9am and it showed it was in ohio and abot 30 min later the doorbell rang
01:55 AM MacGalempsy: i was in okc
01:55 AM Wolf_: yet my ebay order from cali on the 12th says eta of 22
01:56 AM MacGalempsy: sheeet
01:56 AM MacGalempsy: and a cali buy lays tax
01:56 AM MacGalempsy: lays = pays
01:56 AM Wolf_: which are parts I need to finish design work
01:57 AM MacGalempsy: ah. i loaded linux mint onto my acer dual touch screen laptop
01:58 AM MacGalempsy: trying to figure out how to load some terminal code on startup
01:58 AM Wolf_: nice, I loaded mint on a old dell laptop
01:58 AM Wolf_: of course I can’t get laser web to load on startup
01:58 AM MacGalempsy: i got the touchscreens to work right, but have to enter the lines after each start
01:59 AM Wolf_: thats annoying
01:59 AM MacGalempsy: the tutorial said to update a script, but that file is apparently not used on mint
02:00 AM Wolf_: I’m thinking about grabbing another 15” touch screen and loading mint on a acer aspire one that I have laying around
02:00 AM Wolf_: the weird little desktop/vesa mount computer
02:00 AM MacGalempsy: also, i cannot figure out how to activate the onboard keyboard
02:00 AM MacGalempsy: it loads during boot, so i know its there
02:01 AM Wolf_: thats odd
02:01 AM Wolf_: script thing sounds like the same issue I’m having
02:01 AM MacGalempsy: the onboard keyboard is thri the touch screen
02:01 AM Wolf_: oh
02:02 AM Wolf_: onscreen keyboard?
02:02 AM MacGalempsy: built into the bios
02:02 AM MacGalempsy: yeah. the ones that come with mint are weak
02:03 AM MacGalempsy: its an acer iconia 6210
02:03 AM Wolf_: no idea here, I don’t know shit about linux
02:03 AM MacGalempsy: it will just take more reading
02:04 AM MacGalempsy: its like a puzzle
02:04 AM Wolf_: yeah, I have managed to get most things working with much google
02:04 AM MacGalempsy: each walkthru gets l
02:04 AM MacGalempsy: like 80% of the objective done
02:05 AM MacGalempsy: once the main stuff is done, i might load up lcnc
02:08 AM Wolf_: nice
02:08 AM Wolf_: I didnt even bother w/ RT or anything with the dell xps laptop, put newest mint on it
02:37 AM IchGucksLive: HI folks from a Super Spring Morning in Germany
02:39 AM IchGucksLive: Wolf_: still on
02:39 AM Wolf_: morning
02:39 AM IchGucksLive: Wolf_: do you got a Shematic on the Nema Spinle driver
02:40 AM Wolf_: no I don’t
02:40 AM IchGucksLive: 1850 on a 348 is qiote alot
02:41 AM Wolf_: https://www.dropbox.com/s/yis13tmyj1e599s/silverlinedp.pdf?dl=0 what the data sheet says :)
02:43 AM IchGucksLive: Thanks
02:43 AM IchGucksLive: im off
02:44 AM IchGucksLive: Till later
03:26 AM Deejay: moin
03:40 AM MrSunshine: So anyone use the THR25 or similiar bearing blocks and know if you can chain them for lubing ? They got one grease port each atm .. and i would like to remove one, connect them together and only have 1 port for two blocks
03:40 AM MrSunshine: would get me 1.5 - 2cm shorter distance between them and i kinda need that =)
03:50 AM MrSunshine: hmm HSR25
04:25 AM MrSunshine: looks to be throught hole .. would be real nice if i could have just 1 port for each pair ... alot easier to access the greasing =)
04:40 AM Spida: do you manually grease them, or are you looking for automatic greasing?
05:01 AM XXCoder: so much walking at work lately
05:01 AM XXCoder: been assigned to cell and old machine. so theres some distance between those
05:05 AM MacGalempsy: got a step counter going yet?
05:05 AM XXCoder: lol no, but I definitely would have gotten hoime with all mileage
05:06 AM XXCoder: of course I would have to walk back to get my car lol
05:10 AM MacGalempsy: sounds like you need to start applying for the federal rate
05:10 AM XXCoder: ?
05:10 AM MacGalempsy: $0.51/mi
05:11 AM XXCoder: ahh
05:11 AM MacGalempsy: tax deduction ;)
05:11 AM XXCoder: nah most times i sit a lopt
05:11 AM XXCoder: this time is weird as old machine has few very hot jobs
05:11 AM XXCoder: and a61 cell is all caught up and slow
05:12 AM MacGalempsy: im back on the rig this week. its kinda like jail. just been lifting weights
05:12 AM jthornton: morning
05:12 AM MacGalempsy: morning
05:12 AM MacGalempsy: was home for 5 days
05:12 AM XXCoder: its kinda like jail arent it, you cant leave while working
05:12 AM XXCoder: hy jthornton
05:12 AM MacGalempsy: well actually 4
05:13 AM MacGalempsy: pretty much, but this command center has a kitchen, so i get to cook in the office
05:13 AM XXCoder: and less shiv worries eh
05:14 AM MacGalempsy: lol. not too sure about that. the rough necks are sketchy.
05:14 AM MacGalempsy: and they have had a string of thefts
05:14 AM XXCoder: well thats why i said less not no ;)
05:15 AM MacGalempsy: last job some guy wondered onsite and tried to steal a truck. someone pulled in front of the gate
05:18 AM XXCoder: geez
05:18 AM XXCoder: so whats that guy do with truck when blocked
05:19 AM jthornton: sounds like a bad neighborhood
05:52 AM MacGalempsy: we are in the middle of nowhere. lol. i hear its pretty methy around these parts.
05:53 AM jthornton: you in texas?
05:54 AM XXCoder: meth all way in
06:15 AM XXCoder: contest between stormtroopers and red shirts: Stormtroop misses all shots, and red shirt dies anyway. Winner: Stormtrooper.
06:24 AM XXCoder: jthornton: https://i.imgur.com/jZCWbFf.gifv
06:24 AM XXCoder: ouch.
06:24 AM Deejay: lol
06:25 AM gregcnc: one person was expecting it and instead of warning people they filmed it, nice
06:25 AM XXCoder: theres on truism in world
06:25 AM XXCoder: everyone has asshole
06:26 AM gregcnc: but still people just don't think very much anymore. where will all that snow go when the express comes through?
06:27 AM XXCoder: honestly it would be utter olvious to me
06:27 AM XXCoder: snow + train = holy shit manmade blizzard
06:29 AM gregcnc: actually can't tell if people were staring at phones or recording themselves
06:29 AM XXCoder: who knows
06:34 AM gregcnc: what happens when they stop making HDD enclosures https://www.youtube.com/watch?v=8dVsNQSnqyM
06:35 AM XXCoder: dang!!
06:35 AM XXCoder: wonder if all sold by now, it is 4 years old
06:37 AM gregcnc: i wonder what they were getting when there are that many to sell
06:54 AM jthornton: hmm yesterday they said low 20's but it's 34F right now
07:03 AM jthornton: 2.4 pounds to pizza buffet
07:03 AM jdh: 28f
07:48 AM enleth: small success today - I managed to take ORAC apart completely, the only thing that did not come off the bed was the headstock casting, it was visibly shimmed and I didn't want to have to re-shim it
07:48 AM enleth: cleaned it to the point of stripping some paint off
07:49 AM enleth: got the spindle back together, left the rest of it for later
07:51 AM enleth: oh, and it turned out that the back cover is a major structural part of the ORAC's sheet metal base
07:52 AM enleth: it's bolted to a thick steel plate that serves as a motor mount for the spindle and Z axis motors, and is in turn bolted to the bed
07:53 AM enleth: removing any of those bolts immediately makes the whole thing ridiculously wobbly
07:56 AM enleth: among other interesting observations is the fact that I could remove the cross slide by pulling it off the end of the ways, even though it's adjusted pretty snugly in the normal travel range
07:56 AM enleth: if my understanding of machine wear and maintenance is correct, this means that there's no ways wear to speak of at all on this machine
07:58 AM gregcnc: I doubt any Orac have much wear to speak of
07:59 AM archivist: rare that educational machines do much
07:59 AM enleth: heh, yeah
07:59 AM enleth: judging by the chips it was packed full of, all it ever machined was brass and polymers
08:00 AM archivist: my starturn looked pretty unused
08:00 AM gregcnc: even then, only a few parts per week
08:00 AM enleth: it must have seen some use, though - i scraped out a sizeable pile of chips-and-old-coolant gunk
08:01 AM enleth: s/coolant/lubricant/ perhaps
08:01 AM gregcnc: I think in that size machine the ways are fairly oversize compared to the loads
08:02 AM gregcnc: though my compact 6 has worn ways, but I think it was poorly maintained in a shop environment
08:05 AM enleth: one thing I need to consider is whether to weld some steel tubing inside the base, under the bed attachment points, to make it stiffer
08:06 AM archivist: I get chatter, might be worth it
08:06 AM enleth: it would cost me some headroom in the control compartment, but that flimsy sheet metal needs any help it can get
09:21 AM digicnc: Hello
09:21 AM digicnc: I have a question regarding MESA Cards
09:22 AM digicnc: I want to setup a system for a gantry type table
09:22 AM digicnc: using a 7I92
09:23 AM digicnc: I want to drive the system with stepper motors and rotary encoders to create something like a closed loop system
09:23 AM digicnc: anybody done this already?
09:24 AM archivist: closed loop may as well be servo
09:30 AM digicnc: yes closed loop maybe servo
09:30 AM digicnc: but I would prefer stepper motor with encoder
09:30 AM digicnc: just more easy to tune
09:36 AM gregcnc: it has been done, but something like https://www.teknic.com/products/clearpath-brushless-dc-servo-motors/ which take step/dir input would be easier if you don't want servos tuned in linuxcnc
09:40 AM archivist: been done with steppers in the loop as well
09:40 AM gregcnc: yes thaps what i meant
09:44 AM digicnc: this is what I want, clearpath "servo" perfomance with Linuxcnc
09:44 AM gregcnc: but not the price?
09:44 AM digicnc: exactly
09:47 AM digicnc: like the laedshine hybrid servo-stepper
11:38 AM CaptHindsight: why is servo tuning difficult only in some circumstances?
11:40 AM jdh: I have some that run in position mode only. they require no tuning
11:51 AM skunkworks: when the system isn't setup correctly? ;)
11:51 AM {HD}: Just got a Wantai Stepper Driver and the power indicator LED would not illuminate. After some quick tests it was in backwards!
11:53 AM jdh: the led was backwards?
11:54 AM {HD}: Yea
11:55 AM {HD}: It was anode to ground.
11:57 AM jdh: makes you feel confident, eh?
11:57 AM CaptHindsight: http://www.instructables.com/id/Low-Cost-Hobby-Servo-XY-Table/ servo tuning may be a challenge here :)
11:58 AM archivist: people are fooled by RC servos
12:00 PM CaptHindsight: http://www.instructables.com/id/Internet-Arduino-Controlled-T-Slot-XY-Table/ this guy is the master of misuse
12:03 PM {HD}: jdh: lol, Thats a good point. What else is wrong with it? Funny thing is that the QC sticker was right next to the LED indicators.
12:05 PM archivist: at least the sticker states it went through QC, does not say it stopped there for a test :)
12:06 PM CaptHindsight: {HD}: maybe it's a warning LED for power being connected backwards?
12:06 PM CaptHindsight: red light on = bad
12:07 PM {HD}: archivist: lol, yep. I guess What do I expect for a bargin chinese driver.
12:07 PM {HD}: CaptHindsight: It was the green indicator that was in backwards...the red led was in correctly.
12:08 PM archivist: green means it generates smoke correctly
12:21 PM {HD}: If hooking up a stepper motor with twisted pair would you: Hook one coil per pair OR hook a1 and b1 on a pair and a2 and b2 on the other pair?
12:22 PM archivist: both a to a pair
12:22 PM {HD}: archivist: Cool, thanks.
12:47 PM {HD}: With the varient of wire/cables available what type do I want to use where. I need to wire up: 4 lead stepper motors, Limit switches, 400Hz spindle. Should I use shielded, twisted pair, shielded twisted, straight?
12:48 PM archivist: shielded flexible for best
12:49 PM jdh: where are you?
12:50 PM {HD}: jdh: Me? In USA, in the eastern midwest.
12:52 PM jdh: lowes and/or home depot have 2pair stranded 18 and 22gauge by the foot
12:53 PM archivist: use cable chain to help stop breakages
12:53 PM t12: win 12
12:53 PM t12: er
12:54 PM {HD}: jdh: Thanks, I am on their websites now trying to find it.
12:54 PM {HD}: archivist: Yea, I have cable carrier in place.
12:56 PM CaptHindsight: you want super flexible if the cable is moving, or it won't last long
12:57 PM CaptHindsight: for both the conductor and the shield
12:57 PM CaptHindsight: {HD}: if it's not moving, then for signals look at something like this http://www.winford.com/products/wrb10.php
12:58 PM CaptHindsight: they are in southern MI
12:58 PM {HD}: Most of it will me moving...
01:00 PM archivist: larger bend radius lasts longer
01:02 PM archivist: our first printer (dot matrix) would break a cable in 20 minutes, we learned
01:02 PM {HD}: jdh: I don't see it on homedepots website...I am checking lowes now.
01:03 PM jdh: they call it security or alarm wire
01:03 PM {HD}: jdh: Oh, I saw that. I was looking for twisted pair for some reason.
01:04 PM archivist: I dont see security wire as flexible
01:04 PM jdh: I thought they were twisted, but don't really remember. 4 conductor, shielded, stranded
01:05 PM archivist: usually solid core here
01:05 PM jdh: they have both
01:05 PM jdh: I have some of the solid if you want some. didn't notice until I got home!
01:07 PM jdh: not cheap though, $0.63/ft for 18-4 stranded. $0.33/ft for 22-4
01:07 PM {HD}: I guess my main concern is wiring this spindle. Do I need to worry about the 400Hz for any reason?
01:07 PM Tom_L: alarm wire is thinner than cat5
01:08 PM jdh: you have some awfully thick cat5 then.
01:08 PM {HD}: Do you guys have an online supplier that has good prices? I found what I want on mcmaster but they are SO EXPENSIVE.
01:08 PM Tom_L: i had a spool of alarm wire and it was thinner than my cat5 spool
01:08 PM jdh: cool.
01:09 PM Tom_L: the sprinkler wire is heavier
01:10 PM jdh: so is the stuff sold as alarm/security wire at lowes/HD
01:11 PM jdh: https://www.monoprice.com/product?p_id=4043
01:22 PM {HD}: I just found some 22/2 Security wire and it was twisted. About 1 twist an ince.
01:27 PM jdh: IMO, twisted is a nicety, but of dubious value
01:28 PM {HD}: https://www.amazon.com/Security-Burglar-Stranded-Shielded-Control/dp/B00CHXSESI/ref=sr_1_2?ie=UTF8&qid=1489686973&sr=8-2&keywords=18%2F4+security+wire+stranded
01:29 PM jdh: 22/2 for limits?
01:29 PM {HD}: jdh: Thats why I had it. I remembered buying some a year or so ago so, I went to find it.
01:31 PM IchGucksLive: hi
01:31 PM {HD}: Bonjour
01:32 PM IchGucksLive: i lost the Spindle today
01:33 PM IchGucksLive: it just dident start up
01:33 PM {HD}: water cooled?
01:42 PM IchGucksLive: no its a BOSH Wood mill
01:42 PM IchGucksLive: Bosch
01:43 PM {HD}: Suck! Have you done any idiot tests yet? Make sure there is power? Check the switch? Brushes? Fuse? Coils?
01:43 PM IchGucksLive: {HD}: maybve to hard at the part ;-) https://youtu.be/UdvROAlCMMQ
01:44 PM IchGucksLive: i got a BOSCH repair around the parts are 30Euros so i will take the repair offer
01:46 PM Tom_L: IchGucksLive, where are your machining videos? someone was asking about them yesterday
01:46 PM IchGucksLive: Tom_L: https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ
01:46 PM IchGucksLive: this is the channel
01:52 PM IchGucksLive: tiwake: CaptHindsight: what is his channel called?
01:52 PM IchGucksLive: tiwake: ?
01:54 PM CaptHindsight: MAGIG CNC Maschines
01:55 PM CaptHindsight: you might want to check the spelling if you want people to find it
01:55 PM IchGucksLive: No zhis is my real live nick
01:55 PM CaptHindsight: unless that is not supposed to be English
01:56 PM IchGucksLive: and it is why im so bad in spelling
01:56 PM IchGucksLive: its marked on the scale ships
01:56 PM IchGucksLive: and evrywhere i ve been
01:56 PM CaptHindsight: is it supposed to be Magic CNC Machines?
01:57 PM IchGucksLive: no
01:57 PM IchGucksLive: MAGIG
01:57 PM CaptHindsight: ah
01:57 PM CaptHindsight: just checking
01:57 PM IchGucksLive: Thanks
01:58 PM IchGucksLive: CaptHindsight: please can you check some search in youtube US main search bar
01:59 PM IchGucksLive: please enter Linuxcnc Estlcam
01:59 PM IchGucksLive: if my video from yesterday apeard in the first searches
02:00 PM IchGucksLive: Linuxcnc trochoidal
02:00 PM jdh: what's an estlcam
02:00 PM CaptHindsight: https://www.youtube.com/watch?v=8euJ5Tx6ncA and then https://www.youtube.com/watch?v=5c02t1fUIm8
02:00 PM IchGucksLive: YES i did all right if this is the case
02:01 PM IchGucksLive: jdh: https://www.youtube.com/watch?v=8euJ5Tx6ncA
02:02 PM IchGucksLive: CaptHindsight: the 014 version with fixes is out today
02:06 PM CaptHindsight: does MSC still ship out of the old Enco warehouse in Indiana?
02:19 PM IchGucksLive: https://youtu.be/TSvDz0gIbOY ast Known working BOSCH cut
02:19 PM IchGucksLive: Last
02:24 PM CaptHindsight: yes, Enco still ships from Elkhart IN
02:24 PM CaptHindsight: Enco/MSC
02:26 PM IchGucksLive: im off Gn8
02:48 PM os1r1s: Anyone use a shuttleexpress?
03:23 PM {HD}: Should I worry about hooking up a braking resistor to my huanyang VFD?
03:26 PM gregcnc: if you have a large braking requirement, yes
03:27 PM {HD}: wow https://youtu.be/cOMjNhSRAe0?t=2m55s
03:29 PM gregcnc: undersize resistor
03:30 PM {HD}: Because it got RED HOT? Maybe he should put those resistors in a different configuration since only the first one got hot.
03:36 PM roycroft: i can confirm that my huanyang vfd is missing the dymanic braking circuitry, although it is documented as being there
03:36 PM roycroft: 1. dynamic braking does not work
03:36 PM gregcnc: hah oops
03:36 PM roycroft: 2. there's an unpopulated part of the control pcb that is for the dynamic braking components
03:36 PM {HD}: roycroft: Oh No! How would I check that on mine? I donot have a braking resistor to plug in.
03:37 PM gregcnc: is there more than one model?
03:37 PM roycroft: there are several models
03:37 PM {HD}: gregcnc: Yea, lots.
03:37 PM roycroft: mine is a 2.2kw one, btw, because i'm controlling a 2hp motor and like to oversize the vfd a bit
03:38 PM {HD}: roycroft: I did the same. I have a 2.2kw vfd for my 1.5kw spindle.
03:39 PM {HD}: But, I would like to make sure it has the braking resistor functionality when it gets here.
03:39 PM gregcnc: maybe good idea when talking chinacoWatts
03:39 PM roycroft: look at the mach forum thread which is linked on the video you linked to
03:40 PM roycroft: http://www.machsupport.com/forum/index.php/topic,14182.180.html
03:40 PM roycroft: it discusses the missing igbt and how to source and install it
03:40 PM roycroft: you can use that to verify if yours has one or not
03:41 PM roycroft: i would oversize a us-made one a bit as well
03:41 PM roycroft: due to the nature of the devices
03:41 PM gregcnc: even with name brand controls dynamic braking is optional on basic models
03:41 PM roycroft: i also like to oversize ssrs and contactors
03:45 PM {HD}: Hum, So it seems like everything 'missing' will stand out because there is still the silkscreen from where it should be.
03:45 PM roycroft: yes
03:45 PM roycroft: look for a conspicuously "empty" section of the pcb
03:45 PM roycroft: if you find one it will probably be the home for the dynamic braking circuitry
03:45 PM {HD}: Well, mine will be here Tuesday so, the first thing I will do is take it apart.
03:45 PM roycroft: if you don't find one then you probably have the circuitry already
03:46 PM roycroft: of course, the easiest way to tell is to hook up a braking resistor and a motor and give it a go
03:46 PM roycroft: if it stops fast then you have the circuitry
03:46 PM roycroft: if not you don't
03:46 PM sync_: you probably will not need dynamic braking on such a small inertia spindle
03:46 PM roycroft: assuming you've provisioned the thing to use dynamic braking
03:46 PM sync_: speed is not how you check
03:47 PM sync_: the resistor just dumps energy if you are charging your dc link too high
03:55 PM {HD}: Well, I am not to sure what that means. When I get the device I will read the manual and see what I can learn. The braking resistor is for emergency stops? or does it always get used?
03:57 PM roycroft: you can program the vfd to use dynamic braking all the time
03:57 PM roycroft: i don't think there's a way to configure for "normal braking" and "emergency braking"
03:58 PM roycroft: it's an on or off thing for all braking
04:00 PM roycroft: if it's on, when you stop, your motor turns into a generator and dumps current to the braking resistor
04:00 PM roycroft: putting a large load on the motor slows it down
04:00 PM roycroft: er, on the generator
04:00 PM os1r1s: Which UI element shows the jog-step in axis?
04:04 PM {HD}: roycroft: I think I get it. Would the deceleration time matter/effect if using a braking resistor? Or does the braking enable disable decelleration time?
04:04 PM roycroft: that's not clear to me
04:04 PM roycroft: and since i don't have dynamic braking working i cannot test it
04:05 PM {HD}: roycroft: Cool.
04:06 PM roycroft: i should probably modify my vfd soon to support dynamic braking
04:06 PM roycroft: the project for which i purchased it originally is on hold at the moment
04:07 PM roycroft: but i do want to use dynamic braking for it, as it's a belt grinder and i consider a long spin-down time a safety issue
04:08 PM XXCoder: heh at work tool grinder bench has a very dented 1.5" tool by it
04:08 PM XXCoder: we use it to stop grinder
04:11 PM roycroft: dynamic braking is a wee bit more elegant
04:11 PM XXCoder: it is
04:15 PM gregcnc: all depends how much energy you have to dissipate to stop
04:16 PM gregcnc: for a small spindle dc braking will be fine
04:16 PM Crom: fudge... had the amperage set too high on Z axis... over heated driver... waiting for it to cool off
04:18 PM Crom: boys from the robotic team had a stepper motor tied into the motor shaft and use a mosfett using pwm to stop the motor
04:19 PM Crom: actaully 2... for the 2 phases
04:19 PM XXCoder: mine seems to slow and stop effectively as is so its fine for me lol
04:20 PM gregcnc: I have to adjust the vfd on the arboga. last time it seems to overcurrent on DC braking from 80Hz
04:21 PM gregcnc: the Emerson VFD for my lathe project with brake resistor is extremely fast to stop and reverse even from 120Hz
04:26 PM nallar is now known as Ross
04:43 PM JT-Shop: nice
05:03 PM andypugh: So, another department at work have requisitioned my test car to do some work, and have comandeered me to support the testing. They have booked tests for 7am, 2pm and 9pm. Each test takes 30 minutes. So I lose a whole weekend for 3 hours of overtime pay. Which seems like less than a bargain.
05:03 PM andypugh: (I forgot to say, that is Friday, Saturday and Sunday)
05:05 PM JT-Shop: that sucks
05:05 PM JT-Shop: on a good note it seems my design for the pole saw cover tester is a viable design and will work
05:07 PM CaptHindsight: http://linuxcnc.org/ looks like it's down
05:07 PM JT-Shop: which is a good thing at the 11th hour...
05:08 PM CaptHindsight: it's still pingable
05:08 PM andypugh: Forum is up
05:08 PM JT-Shop: up for me
05:09 PM andypugh: www.linuxcnc.org is up. linuxcnc.org is not
05:10 PM CaptHindsight: might be a regional thing since www is also down and http://downforeveryoneorjustme.com/ also has it a s down
05:12 PM CaptHindsight: http://isitdownorjust.me/linuxcnc-org/ also down
05:13 PM evilren: cradek: omg fix all the things
05:13 PM CaptHindsight: lol
05:13 PM andypugh: Ah, wait, I was probably seeing a cached version…
05:13 PM roycroft: linuxcnc.org and www.linuxcnc.org share an ip address
05:13 PM roycroft: if i were managing that domain's dns i would make www.linuxcnc.org a cname for linuxcnc.org
05:14 PM roycroft: as it is, the hosting provider needs to have both hostnames configured to point to the website
05:14 PM roycroft: with a cname it would only need linuxcnc.org
05:14 PM roycroft: unfortunately, linuxcnc.org cannot be a cname for www.linuxcnc.org
05:15 PM CaptHindsight: the forums work
05:15 PM CaptHindsight: but the main site and wiki are down
05:16 PM roycroft: correct - i cannot connect using either hostname
05:17 PM roycroft: somebody needs to give dreamhost a swift kick in the rear
05:18 PM CaptHindsight: usually this only happens when I need to check a link on the wiki for something I'm working on that needs to be done in the next few minutes
05:19 PM CaptHindsight: I'm not in a hurry so I don't understand why the site is down now :)
05:20 PM roycroft: because someone else is in a hurry
05:20 PM roycroft: you're not the center of the universe you know :P
05:20 PM roycroft: right now somebody else is the center of the universe
05:21 PM CaptHindsight: we all need our rest :)
05:30 PM {HD}: Would 14/4 SJOOW be good for a spindle to VFD cord? I guess my main concern is the flexability.
05:31 PM andypugh: I have no opinion because I have no idea what you are describing
05:31 PM Crom: Project Binky posted Epi 15... It's only on Patreon right no
05:31 PM Crom: 35minutes
05:31 PM andypugh: But I prefer to use specific cable-chain rated and oil-resistant cables.
05:32 PM {HD}: https://images1.mcmaster.com/mvA/contents/gfx/small/7422kd1-d01b-gis.png?ver=1433232080
05:32 PM Crom: {HD}, you really need a shielded cable... SJOOW is not shielded
05:33 PM {HD}: Crom: I understand. Any recommendations on what to look for?
05:33 PM Crom: how many watts is you spindle?
05:34 PM Crom: and voltage
05:34 PM {HD}: I have both a 1.5kw and 2.2kw I am setting up. 240v on each.
05:34 PM andypugh: I used this for my servos: https://www.rapidonline.com/Cables-Connectors/LappKabel-1026769-LFLEX-CHAIN-809-CY-Grey-Drag-Chain-Cable-4-x-1mm-63-4337
05:34 PM {HD}: maybe 220v...
05:36 PM Crom: 2200watts at 220v ==10amps so 16awg 14awg would be better
05:36 PM {HD}: andypugh: I like the look of that. I need to find it in the US and what gauge is 1mm^2?
05:37 PM Crom: http://www.stayonline.com/reference-circuit-ampacity.aspx
05:37 PM {HD}: Crom: Yep I was thinking 14awg depending on the flexability.
05:37 PM andypugh: 1mm2 is rated 10,5A for 3-phase in conduit to UK spec, but you might want to go to 1.5mm for peace of mind.
05:38 PM andypugh: {HD}: Searching on Google should find you a US source.
05:40 PM CaptHindsight: {HD}: http://www.ecdcontrols.com/electrical-components.1472/driveflex-pvc-shielded-flexible-vfd-motor-supply-cable.aspx for example
05:40 PM Crom: This is top notch cable teflon, no pvc $160 FOR $25 http://www.igus.com/Shop/Product/1015?tab=ProductDetails
05:41 PM Crom: This is top notch cable teflon, no pvc $160 FOR 25' http://www.igus.com/Shop/Product/1015?tab=ProductDetails
05:42 PM CaptHindsight: http://muellergroup.net/product-category/festoon-crane-handling-cable/ robot cable
05:42 PM Crom: $50 FOR 25' 4 x 14awg http://www.igus.com/Shop/Product/994?tab=ProductDetails
05:44 PM andypugh: This might suit, 4 cores 14AWG + a smaller pair for signal (temperaure, brake) http://www.alliedelec.com/lapp-group-u7412044/70124748/ ANd you can buy it buy the foot.
05:45 PM Crom: though it depends on what the VFD uses for voltage to the spindle. 2200w at 110v is 20amps you would want to go with a 12 or 10awg cable
05:45 PM {HD}: You guys are awesome. I am going to read all of these pages and see if I can narrow down my decision.
05:46 PM andypugh: Oh, don’t come here to _narrow_ down your choices..
05:47 PM CaptHindsight: http://www.newark.com/alpha-wire/85604cy-bk005/shielded-multiconductor-cable/dp/91F2659
05:48 PM CaptHindsight: the super flexible cables will use many very small copper conductors to make up the conductors
05:48 PM Deejay: gn8
05:48 PM Crom: yay! 2gb mem stick arrived for linuxcnc machine
05:48 PM CaptHindsight: to make up each 16ga conductor it uses 168 x 38AWG
05:49 PM CaptHindsight: vs fewer large conductors
05:50 PM Crom: and USB B connectors arrived... I can fix my uno I stole the USB connector off to fix my hp 1320 laser jet
05:51 PM Crom: bbiaw putting memory in
05:52 PM CaptHindsight: cables with lower flex might only have 26 x 30ga to make up the #16
05:52 PM CaptHindsight: flexible but not as much as using 168 x #38's
05:52 PM Tom_L: CaptHindsight, who was asking about ick's videos?
05:52 PM Tom_L: he posted that earlier today
05:53 PM CaptHindsight: Tom_L: someone was asking about basic machining videos for someone new to CNC
05:53 PM Tom_L: oh
05:53 PM CaptHindsight: ich said he had several on his youtube channel
05:54 PM CaptHindsight: might have been tiwake asking
05:54 PM Tom_L: he's got quite a bit of stuff there
05:54 PM CaptHindsight: I didn't know what ich called his channel
05:56 PM Tom_L: https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ
05:56 PM CaptHindsight: MAGIG CNC Maschines
05:56 PM JT-Shop: CaptHindsight: I have 250 3.7 standoffs in the works!
05:57 PM CaptHindsight: making a bunch this time :)
05:58 PM tiwake: CaptHindsight: yeah, was me :P
06:02 PM CaptHindsight: https://www.youtube.com/channel/UCrwn2uKl16pnC-GMgB75Cag only has a few videos
06:09 PM Cromaglious_: yay memory works!
06:09 PM Cromaglious_: still have over 750MB's free
06:12 PM os1r1s: Does anyone know if the 7i76 inputs are pulled up or down by default?
06:14 PM JT-Shop: os1r1s: http://gnipsel.com/linuxcnc/configs/7i77.html
06:16 PM os1r1s: JT-Shop Awesome. Thx
06:19 PM os1r1s: Lesson of the day. End mills are razor sharp and rip through skin even when still
06:22 PM CaptHindsight: SINKING INPUTS 7I76 field inputs are of the sinking type.
06:22 PM JT-Shop: if you think an end mill is sharp try an onshrud plastic end mill
06:23 PM jesseg: hey what do you think of this? I got 20M of 1mm core plastic fiber optic with black plastic jacket, to run my encoder signals back to my controller on. That way they don't pick up any noise from the long run.
06:24 PM * JT-Shop calls it the end of a long day
06:24 PM CaptHindsight: jesseg: did you get inexpensive fiber transcievers as well
06:25 PM CaptHindsight: jesseg: thats what the precise robots do as well
06:25 PM CaptHindsight: fiber from encoders back to controller
06:26 PM jesseg: CaptHindsight, haven't got the fiber transceivers yet, although I've experimented with them a decade ago for other purposes, basically a little plastic mount that takes a regular cheap photo emitter/detector
06:26 PM Cromaglious_: ok X cable is now out...
06:26 PM Cromaglious_: FUDGE!
06:27 PM jesseg: CaptHindsight, I hadn't heard of precise robots before
06:28 PM jesseg: ahh, a commercial venture?
06:28 PM jesseg: I guess if they went to fiber optic they must have found a unique benefit to it
06:28 PM CaptHindsight: precise/precision
06:29 PM CaptHindsight: http://www.staubli.com/en/robotics/ for example
06:30 PM jesseg: I wonder if plastic fiber optic works for a laser ring gyro
06:30 PM jesseg: and I wonder if it'd work without the jacket.. because 0.75mm bare plastic fiber sure is cheap from China :P
06:31 PM jesseg: cool robot
06:32 PM CaptHindsight: http://www.mouser.com/new/broadcom/broadcom-afbr-1555arz-afbr-2555arz/
06:32 PM CaptHindsight: fiber has typically been the low cost part
06:33 PM CaptHindsight: it's the connectors and transceivers that used to be pricey
06:33 PM jesseg: those look expensive, they have metal cases :P
06:33 PM jesseg: oh not as bad as I thought
06:33 PM CaptHindsight: for cnc machines
06:34 PM CaptHindsight: you can also buy the plastic stuff
06:35 PM jesseg: see check this out: http://www.digikey.com/product-detail/en/industrial-fiberoptics/IF-D92/FB121-ND/243778
06:35 PM CaptHindsight: http://www.mouser.com/ProductDetail/Broadcom-Avago/HFBR-2522Z/?
06:37 PM CaptHindsight: getting pretty lowbrow there
06:38 PM jesseg: In a way it's too bad the encoder can't simply have an IR led and the optical gratings then instead of photo sensors on the motor, just run them into the fiber optic
06:38 PM CaptHindsight: cut too many corners and what do you have
06:39 PM jesseg: it would require running 4 fibers since it's generally two balanced pair photosensors
06:39 PM CaptHindsight: http://www.micronor-inc.com/products.php?category=Fiber+Optic+Rotary+Encoders&offset=0
06:39 PM jesseg: hahaha ok so they did it :P
06:40 PM CaptHindsight: not budget models
06:40 PM jesseg: naturally but we're all machinists :P
06:42 PM jesseg: Interesting... I think they are using only two fibers
06:43 PM jesseg: I wonder exactly how they make that work
06:43 PM roycroft: they could be using wave division multiplexing
06:44 PM roycroft: but that's pretty expensive technology, so probably not
06:44 PM jesseg: oh, like using one fiber to send red and green light, then the other to retrieve red and/or green depending on the encoder?
06:44 PM roycroft: yes
06:45 PM roycroft: but you have to mux the colors together at the transmit end and demux them at the receive end
06:45 PM roycroft: and that requires using microprisms
06:45 PM roycroft: and they are expensive
06:46 PM roycroft: but it is possible
06:47 PM roycroft: i have a fiber network that i operate which only has two strands available to our head end, which is about 55km north of the town where the network is located
06:47 PM roycroft: and we'll only ever be able to have two strands
06:47 PM roycroft: but i have equipment that does dense wave division multiplexing
06:47 PM roycroft: i can mux up to 128 lambdas (colors) on those two strands
06:47 PM roycroft: each lambda can carry 100Gb/s of traffic with current technology
06:48 PM roycroft: and soon it will be able to carry 1Tb/s per lambda
06:48 PM roycroft: so even though there are only two strands, my potential bandwidth is almost infinite
06:49 PM CaptHindsight: two fibers, one for each phase
06:49 PM roycroft: i use one for tx and one for rx
06:49 PM jesseg: CaptHindsight, but somehow the light is also sent to the encoder over the fiber.
06:49 PM CaptHindsight: not sent as data, just on/off high low for each phase
06:50 PM roycroft: there is technology to pass bidirectional signals on a single strand, but that is severely bandwidth-limited
06:50 PM CaptHindsight: I think we are just talking about the parts under $20
06:51 PM roycroft: yes, i'm certain the type of technology i use is not on thos encoders
06:52 PM CaptHindsight: I remember paying $200 a transceiver for 1gb and the connectors were way more
