01:54 AM Deejay: moin
03:09 AM jesseg_phone: Howdy!
03:13 AM Loetmichel: gnihi, sometimes you could think we were a Metal workshop here instead of an IT company... 1 coworker is sanding off freshly milled 19" front panels for powder coating, the second is drilling screw holes in a rack enclosure, the third is repairing bent desktop PC cases, the fourth is cutting copper foil for shielding and i am deburring a newly milled keypad drawer out of sheet alu :-)
04:53 AM jthornton: morning
04:55 AM Loetmichel: maaan, sometimes i love this company
04:56 AM XXCoder: :)
04:56 AM XXCoder: hey
04:56 AM XXCoder: today was supppper stuffy
04:56 AM XXCoder: 60% humidity in shop
04:56 AM XXCoder: felt like I could just wave cup around and drink water
04:57 AM XXCoder: or not bother with cup and walk faster with mouth open
04:58 AM Loetmichel: just sat at the mill, moved it by hand jogging to mill down the sides of this Enclosure 1,2mm that we can fit a EMI gasket on that corners... while a coworker is holding down the enclosure by hand, it resting on its rubber feet and already all electronics installen... FUN jobs ;) (kinda loud, too) -> http://www.cyrom.org/palbum/main.php?g2_itemId=17235&g2_imageViewsIndex=1 ... OSHA would
04:58 AM Loetmichel: have had a field day ;)
04:59 AM Loetmichel: (customer sent us back one of the prototypes to upgrade to the series build)
05:03 AM Tom_itx: morning
05:23 AM Tom_itx is now known as Tom_L
05:23 AM XXCoder: Ouch
05:23 AM XXCoder: https://www.youtube.com/watch?v=RfB7YWZ5j6E
06:32 AM Wolf__: *clicks vid link
06:41 AM Wolf__: nice crunch
06:41 AM XXCoder: but was it creaking or something before it?
06:41 AM Wolf__: yeah, it was making some noise soon as he started jacking the car up
06:42 AM XXCoder: guy was saying he centered it correctly
06:42 AM XXCoder: in comments
06:42 AM XXCoder: i was thinking ehh maybe not
06:42 AM Wolf__: 2 little pucks on the jack pad = fail waiting to happen
06:43 AM Wolf__: if I need spacers on my jack I always use x6 lumber
06:43 AM XXCoder: pucks?
06:44 AM Elmo40: pucks crumble
06:44 AM Wolf__: yeah, he had what looked like 2 hockey pucks on the floor jack as spacers
06:44 AM Elmo40: and lumber splits
06:44 AM XXCoder: oh literal pucks
06:44 AM Wolf__: lumber does split, but at least it wont roll off the jack lol
06:44 AM XXCoder: hockey puck
06:45 AM XXCoder: didnt notice that when first watched
06:49 AM Wolf__: small stacks of anything on floor jacks like that are a bad idea because the jack has to move while lifting
06:49 AM XXCoder: i felt he was misinterpeting what happened
06:49 AM XXCoder: I guessed right
06:51 AM Wolf__: wannabe tuner imo, not surprised lol
06:51 AM XXCoder: tuner?
06:51 AM Wolf__: car modder
06:51 AM XXCoder: oh
06:51 AM XXCoder: that car looks expensive
06:51 AM XXCoder: like 10 of my car expensive
06:53 AM sensille: is 10 of your cars already expensive?
06:53 AM XXCoder: $20,000
06:53 AM XXCoder: so 10 of my car would be $200,000
06:54 AM sensille: i'd have guessed $2000 -> $20,000 :P
06:55 AM XXCoder: lol
06:57 AM Wolf__: Lexus 2016 GS-F ~$85k
06:58 AM Wolf__: like $5k short of what my truck cost and over 2x of my ’15 vw
07:00 AM XXCoder: so basically 4 of my car and some cheap car
07:00 AM Wolf__: but that $85k is new cost
07:01 AM XXCoder: yeah not expecially expensive but not average
07:01 AM XXCoder: my car new would be maybe 50k?
07:02 AM XXCoder: if even that high
07:02 AM Wolf__: one of his vids says it bought it used w/ 8k miles on it
07:03 AM Loetmichel: XXCoder: i know that sinking feeling in that vid... had my first old BMW E36... tried to change the winter tyres to summer ones...
07:04 AM Loetmichel: put the jack under the lift point. Pumped... and pumped... the jack simply disappeared into the frame without any resistance
07:04 AM XXCoder: uhh
07:04 AM Wolf__: thats never good lol
07:04 AM XXCoder: rust?
07:05 AM Loetmichel: had to put a 1by4 under the jack point to distribute load: http://www.cyrom.org/palbum/main.php?g2_itemId=16289
07:05 AM Loetmichel: rust indeed ,)
07:05 AM Wolf__: if possible I always use a sub-frame bolt as a jack point
07:06 AM Elmo40: that won't pass a safety
07:06 AM Loetmichel: elmo: i bought that car for 400 eur, as a commuter car until my Opel Omega was back from engine rebuild
07:07 AM Loetmichel: and i did good, took the sho 4 months to do said rebuild
07:07 AM Loetmichel: sold it afterwards for 100 eur :-)
07:07 AM Elmo40: nice.
07:07 AM Loetmichel: not bad for being able to drive for 4 months ;)
07:08 AM Wolf__: my fav fucked up car so far has been my 2000 ford ranger, $300 (or was it $150…) had a odd noise in the rear when I test drove it, got it home and found the rear leaf spring poking in to the bed
07:08 AM Loetmichel: way cheaper than 4 months of rental ;)
07:08 AM Wolf__: rear spring hangers totally rusted off
07:08 AM Loetmichel: hihi
07:09 AM XXCoder: reminds me of my friends old car
07:09 AM XXCoder: it was wooby as hell
07:09 AM Loetmichel: my dad had an Audi 100 for decades... when he finally sold it to a student for the equvalent of 2 cases of beer...
07:09 AM XXCoder: and 90 degree turns were white knucle affair.
07:10 AM Wolf__: truck drives great now, needs a new clutch and the ac fixed
07:10 AM Loetmichel: ... he asked the student a few months later how the car is doing: "oh, had to scrap it.. lost the whole rear "axle" on a speed bump. Both coilovers on the rear fell out when the car got air time"
07:10 AM Wolf__: haha
07:11 AM XXCoder: lol
07:11 AM Loetmichel: bolts/domes rusted off, only held in by gravity ,)
07:12 AM Wolf__: worst is the ’69 bronco I have, when I pealed off the bondo it turned out the body tub was rusted in to 3 pieces
07:13 AM Wolf__: body filler 2”/5cm thick in some spots
07:14 AM XXCoder: cars I owned overall was pretty good
07:15 AM XXCoder: though my first car was toyata with wayyy underpowered engine
07:15 AM XXCoder: could stall and stop on uphill drive
07:15 AM XXCoder: my sis in law borrowed car once, got stuck on hill lol said never again borrow
07:15 AM XXCoder: i knew how to get around it, but she didnt
07:15 AM Wolf__: still kicking myself for selling my first car… ’71 chevelle
07:18 AM XXCoder: i miss mecury sable car
07:18 AM XXCoder: got totaled. :(
07:19 AM Wolf__: my mom had a sable station wagon, that was 1/2 way my first car, which I totaled lol
07:22 AM Loetmichel: Wolf__: i had to change a fender on that 316: http://www.cyrom.org/palbum/main.php?g2_itemId=16277
07:22 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16280
07:22 AM Loetmichel: that was what all the lower "frame" looked like
07:22 AM Loetmichel: good thing i bought it as a beater and didnt try to rebuild it at all ,)
07:22 AM Wolf__: lol looks like it came off easy =D
07:23 AM Loetmichel: a bit TO easy for my taste
07:23 AM Loetmichel: wasnt fixed on the lower part any more at all
07:24 AM Wolf__: yeah I see that
07:24 AM Loetmichel: the next i bought was a LOT better
07:24 AM Loetmichel: only one spot to fix
07:25 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16715
07:25 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16821
07:25 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16824
07:25 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16830
07:26 AM Wolf__: that does look better
07:26 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16842
07:26 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16845
07:26 AM Loetmichel: like new ;)
07:26 AM Loetmichel: ... not bad for a rattlecan paintjob ;)
07:28 AM Wolf__: my former beater https://i.imgur.com/LzQDJAK.jpg i now have a ’94 that I need to fix up and put on the road for shop beater
07:29 AM Loetmichel: nice
07:29 AM Loetmichel: would like to have a pickup
07:29 AM Loetmichel: but the classics are insanely expensive here in germany
07:29 AM Loetmichel: things like F100 or F150 or D200
07:30 AM Loetmichel: that and a 3 series BMW convertible and i am settled
07:30 AM Loetmichel: then the 525i station wagon i drive today would be obsolete
07:31 AM Loetmichel: maybe 10 years from now the tesla pickups will be cheap enough to be in my price bracket, who knows?
07:31 AM Wolf__: yeah, still waiting to see what that is going to look like
07:34 AM Wolf__: The rivian pickup kinda looks nice but I’m apprehensive because its a more of a startup company
07:35 AM Loetmichel: out of my price bracket as well
07:35 AM Wolf__: that problem #2 lol
07:35 AM sync: none of those will ever be in your price bracket
07:39 AM Loetmichel: sync: depends
07:39 AM Loetmichel: crash vehicle maybe
07:39 AM Loetmichel: :-)
07:39 AM Loetmichel: weld on a new nose, done ;)
07:40 AM Wolf__: other problem is the tesla pickup is still vaporware imo
07:43 AM Wolf__: hopefully they will make it w/ a 8 foot bed… other thing I dont like about the other EV trucks on the market
08:15 AM Loetmichel: i would like to buy an Ecocraft carrier... had one on mobile.de on "watch"... for 2700 eur witzhout batteries
08:16 AM Loetmichel: the day i got my small inheritance on my account i lokked at it: gone :-(
08:16 AM Loetmichel: THAT would have been perfect for me
08:16 AM Loetmichel: no electronics other than the drive inverter, no steering assist, no airbags or ABS... simple as can, easy to repair
08:17 AM Loetmichel: only 100km range though
08:19 AM Loetmichel: i probably would have bought 6 small car batteries and rented a 6kw petrol genset, strap it on the back and drive it home the 250km from the seller with the genset running ;)
08:19 AM Wolf__: lol
08:20 AM Loetmichel: and then see to it to get nice lifepo4 batteries for it ;)
08:28 AM -!- #linuxcnc mode set to +v by ChanServ
11:06 AM perry_j1987: morning
11:07 AM perry_j1987: Wolf__ that youtube girl that makes the crapy robots made a tesla truck heh
11:26 AM Loetmichel: perry_j1987: yes, thats the one we talked about earlier
11:27 AM Loetmichel: problem i have with a tesla UTE or pickup: its tesla. A.k.a very expensive and locked into tesla repair facilities.
11:28 AM Loetmichel: if i can help it i would like a car that uses standard components better
11:28 AM Loetmichel: that are aviable off the shelf and from third sources
11:34 AM Jymmm: Loetmichel: Got ya covered... https://a57.foxnews.com/a57.foxnews.com/static.foxnews.com/foxnews.com/content/uploads/2018/11/640/320/1862/1048/Fred-Flinstone-Smart-Car-3.jpg
11:36 AM perry_j1987: lol
11:36 AM perry_j1987: Loetmichel lot of people converting elcaminos to eletric with forklift electric motors
11:39 AM Jymmm: perry_j1987: sounds interesting, direct drive or ???
11:39 AM roycroft: one can put a lot of batteries in the back of an el camino
11:40 AM perry_j1987: adapter plate into existing transmission
11:40 AM Jymmm: interesting
11:40 AM roycroft: just build a deck over the existing bed, and it can still haul cargo
11:41 AM Jymmm: But li-ion batteries being key
11:41 AM perry_j1987: they put batteries in front
11:41 AM perry_j1987: motors not that big
11:44 AM Jymmm: perry_j1987: waht batteries are they using?
11:44 AM rentanick2232: can anyone help me with a configuration of a pwm controlled spindle?
11:44 AM perry_j1987: that i dont know last time i seen one in person was 10 years ago
11:44 AM Jymmm: rentanick2232: Best to just ask your question in here, if anyone an help, they will
11:45 AM Jymmm: perry_j1987: ah ok
11:45 AM perry_j1987: i just remember talking to a guy that did it and it all looked very easy
11:45 AM perry_j1987: he said the forklift eletric motor to existing tranny made it real simple
11:45 AM gloops: rentanick2232 any more details? not sure what youre asking
11:46 AM perry_j1987: everything else was just oversized RC car basically heh
11:46 AM Jymmm: perry_j1987: with remote control?
11:46 AM perry_j1987: well he must have done something to convert the gas pedal to throttle etc heh
11:48 AM Jymmm: perry_j1987: Maybe used the turn signle as forward reverse stop =)
11:49 AM perry_j1987: i imagine he kept the turn signals as turn signals lol
11:49 AM Jymmm: whre's the fun in that
11:54 AM perry_j1987: so i have to make some gcode to try this threadmill out today
11:54 AM perry_j1987: and i dont want to break it
12:01 PM rentanick2232: I have a 5 axis bob for a controller ouputiing a 0-10v pwm signal hooked to a unknown "huangyaun" style vfd 0-400 Hz. This vfd has a minimum frequency programmed to 120Hz (otherwise it can burnout my spindle). I used stepconf to configure 7200 rpm = 0.0 output and 24000rpm =1.0
12:03 PM rentanick2232: However, when i manually test by setting gcodes s18000 and m3 the spindle will set a frequency of 180Hz. s23000 will set the vfd at 300Hz and s24000 sets 400Hz.
12:04 PM rentanick2232: can anyone advise as to whether i need to manually set some kind of scale factor in the HAL file?
12:04 PM rentanick2232: also, can anyone tell me how to find the correct pwm rate to set
12:04 PM rentanick2232: ?
12:05 PM rentanick2232: thanks in advance for any pointers
12:06 PM rentanick2232: BTW, i have the PWM rate set currently to 50Hz, which was set completely arbitrarily
12:10 PM jym: ghetto fabulous knife sheith
12:12 PM perry_j1987: Tom_L you around
12:13 PM Tom_L: no
12:14 PM jym: LEave a message at the beeeee..................................................
12:14 PM Tom_L: headin out in a few min
12:14 PM perry_j1987: ah was hoping you had some conservitive threadmill settings i can start with
12:15 PM Tom_L: in or metric?
12:16 PM perry_j1987: metric
12:16 PM Tom_L: ick
12:16 PM perry_j1987: i can convert to save you time if your running out the door though
12:17 PM Tom_L: if it's a big thread i'd make 2-3 passed progressively deeper
12:17 PM perry_j1987: 1mm pitch thread
12:17 PM Tom_L: i can generate one with my thread macro when i get back if you want
12:18 PM Tom_L: but mine is set for inch so i'd have to convert it all
12:19 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/threadmacro_multipass2.jpg
12:19 PM Tom_L: it will generate internal or external with a lead in and lead out move with as many passes as you want
12:19 PM perry_j1987: nice
12:19 PM perry_j1987: whats it written in?
12:19 PM Tom_L: my cad cam macro language
12:20 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arc_leadin_percent.jpg
12:20 PM Tom_L: that was the final rev i think
12:20 PM Tom_L: uses arc leadin / out moves
12:20 PM jym: My $0.50 knife, removed the nicks, reshaped the cutting edge as it had a curve on the tail and wasn't sitting flat, sharpened to almost razor sharp, then took forever to heat,fold, clamp the sheath, but fits nicely... https://i.imgur.com/qTp7E73.jpg
12:21 PM Tom_L: with an equal percentage of thread each pass
12:21 PM Tom_L: perry_j1987, here it is if you think you can use it :D http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/ThreadMill_arc_percent.mcl
12:21 PM Tom_L: i doubt it
12:22 PM Tom_L: you can see the input required
12:23 PM Tom_L: bak in a couple hrs
12:23 PM perry_j1987: ok
12:24 PM Tom_L: what thread mill did you get?
12:27 PM gloops: rentanick2232 been a while since i did huan spindle on mine, did you set the scale in stepconfig?
12:28 PM rentanick2232: i am running linuxcnc 2.8 i do not see an option in stepconf to set a scale factor
12:29 PM rentanick2232: i just know that you can set it manually in the config
12:31 PM gloops: hmm, not got hal file on this pc, can have a quick look on cnc pc
12:32 PM rentanick2232: want to remote to my cnc?
12:32 PM jym: O_o
12:33 PM rentanick2232: https://i.imgur.com/TDUqlMB.png
12:34 PM perry_j1987: its good for 1mm pitch
12:34 PM gloops: one moment
12:34 PM perry_j1987: .180" cutter diameter
12:35 PM jym: Ewwww WINDOWS!!!!
12:37 PM rentanick2232: its the one pc that runs MS
12:37 PM rentanick2232: i swear
12:37 PM jym: rentanick2232: Uh huh, Suuuuuure it is ;)
12:38 PM perry_j1987: hmm there's a new probing section in the menu on fusion360 now
12:39 PM gloops: https://textuploader.com/1dwuk
12:39 PM gloops: thats my half for 2.8
12:39 PM gloops: hal
12:39 PM jym: rentanick2232: I run XP in VM's, except for my netbook, and that's only because I can't find a 32bit OS/browser that will do netflix
12:39 PM gloops: note this line - setp parport.0.pin-01-out-invert 1
12:40 PM jym: gloops: (is there a pin-00- too?)
12:40 PM rentanick2232: why is it important?
12:41 PM gloops: tbh i cant remember lol, but i had to invert the pin for some reason
12:41 PM gloops: sticks in my mind it wasnt happening without it
12:41 PM rentanick2232: https://pastebin.com/Tzr6Wwd5
12:42 PM gloops: jym err..not sure lol
12:42 PM jym: gloops: okey =)
12:44 PM gloops: i set it up in the dark days one winter and it took ages and scarred me mentally, i think ive blocked the memories out
12:50 PM jym: I'm wanting to add air-assist to my laser. Silicone tubing is just a little too flexible, and would rather NOT use anything PVC, needs to curve back-and-forth (much like energy chain does, any suggestions on the tubing to use? about 1/8 to 1/4 inch ID???
12:51 PM jym: 1/8" ID
12:51 PM Rab: jym, plain ol' rubber vacuum hose from the auto parts store?
12:51 PM jym: Rab: Think that will not flop around and still flexible enough when cold?
12:52 PM jym: Rab: we are talking 40ips rapids
12:52 PM Rab: jym, I feel that it is more flexible than PVC and less than silicone.
12:52 PM perry_j1987: jym compressed air or blower air
12:53 PM perry_j1987: you can wrap wire around the silicone where it bends like a spring
12:53 PM perry_j1987: to keep it from flopping
12:53 PM Rab: And in its main application, it survives a whole lot of vibration, repetitive flexing, and environmental abuse.
12:54 PM jym: perry_j1987: maybe a small diaphram pump, or ntrogem gas.
12:54 PM jym: Rab: True, but usually the engine heat warms it, and not intended for continous movement
12:55 PM Rab: The pneumatic motion controlled stuff I've taken apart generally seems to use rubber or latex tubing.
12:55 PM perry_j1987: what is energy chain
12:56 PM Rab: jym, good point that it's usually in a warm environment. Although the same stuff is used for window washer plumbing, often outside the engine compartment.
12:56 PM gloops: rentanick2232 some parameter settings need to be right on the vfd (if you havent used this type before) assuming you have the manual?
12:56 PM Rab: perry_j1987, https://www.cableorganizer.com/igus/echain-series-e08-chain.html
12:56 PM gloops: another thing, when playing with the settings - dont turn the power off while the spindle is still turning
12:56 PM rentanick2232: i believe i have set the vfd parameters
12:57 PM perry_j1987: ah cable chain
12:57 PM perry_j1987: my 6040 uses what looks like that clear aquarium tubing for the water lines
12:57 PM perry_j1987: inside cablechain np
12:58 PM jym: Rab: Yeah, I might give that a shot.
12:58 PM jym: perry_j1987: That's typically clear PVC tubing - PVC is VERY BAD for lasers
12:58 PM perry_j1987: bad how
12:59 PM perry_j1987: you wouldnt be shooting a laser through it?
12:59 PM perry_j1987: imagine there'd be all kinds of other problems if it got in the beam some how heh
12:59 PM Rab: If your laser is cutting throught the coolant lines, you might have bigger problems than a little chlorine gas. ;)
12:59 PM jym: perry_j1987: PVC + LASER = HCL GAS, evil to breath,a dn evil for the laser itself
12:59 PM gloops: pretty sure you can set spindle scale in stepconfig though
12:59 PM perry_j1987: ya that sounds like somewhat of a non-issue
01:00 PM gloops: this is where Ichs was useful, he built these type of chinese machines every day
01:00 PM perry_j1987: if your cable chain is ever in the beam you've already failed lol
01:00 PM jym: perry_j1987: there is no energy chain, this is all free standing tubing. If it ever came undone, it could hit the laser without realizing it
01:01 PM perry_j1987: oh i thought you said it would be going in cable chain
01:01 PM perry_j1987: np
01:02 PM perry_j1987: even still zipties dont generally come undone and wiring/tubin should always be properly secured on motion platforms
01:03 PM gloops: Ichs video on setting chinese vfd/spindle up https://www.youtube.com/watch?v=anf0RdROedQ
01:03 PM jym: perry_j1987: This is what happens when you've been running the same parts all day, then goto answer the door to grab a package from UPS for 90 seconds... https://i.imgur.com/3XLHedY.jpg A $30,000 ooooops that insurance DID NOT cover.
01:04 PM perry_j1987: ouch
01:04 PM gloops: 12:30 into that video - setting spindle scale in stepconfig
01:05 PM gloops: max frequency = 400 = max speed 24000rpm
01:28 PM JT-Shop: jym: that wire bundle rubbing on the frame and shorting out was the cause of the random misfiring of the engine
01:29 PM jym: JT-Shop: The one BARELY wrapped in black tape at the end of the bundle?
01:30 PM jym: JT-Shop: IT looked like it had been wearing down to me
01:32 PM jym: JT-Shop: Glad that was a simple enough solution. The cause can be so damn hard to isolate most of the time. The other codes (to me) seemed "Eh, the effect, not the cause". Heh, probably the LAST place you would have ever looked for it too. Would have been that way for me at least.
01:39 PM jthornton: well not quite so simple, I'm pulling the truck bed off so I can do a proper job hooking the canister valve and retape the wires
01:40 PM jthornton: when I took the truck out of the shop to turn it around it ran smooth as silk
01:54 PM perry_j1987: fusion 360 is crashing trying to preview threadmilling toolpaths
02:11 PM CaptHindsight: good thing it's free and well supported
02:13 PM perry_j1987: aye heh
02:13 PM jym: JT-Shop: Well, still finding the root cause in rats nests of automotive wiring harness (if it was just wiring and not some oddball $200 sensor) is a good thing. Just because you want to do it right, and not redneck it with wire nuts is your own damn fault ;)
02:15 PM jym: Now if I could figure our why I'm loosing so much power and sucking gas mileage I'd be a happy camper
02:17 PM jym: The engine seems fine, no codes, I'm guessing something with the trans of torque converter, but I really have no clue at all about that or even how do diagnose. Can old trans fluid become that thin???
02:18 PM jym: Can you suck out the torue converteer yourself? how?
02:19 PM Deejay: re
02:19 PM Tom_L: perry_j1987 did you get a threadmill toolpath generated?
02:19 PM perry_j1987: yes im trying to figure out speeds and feeds for all this to start testing
02:20 PM Tom_L: hardly any chipload on those cutters
02:20 PM perry_j1987: planning on using a 1/2" endmill to mill some square stock to have a boss on it and then switch to thread mill and put exterior threads on the boss
02:21 PM Tom_L: does f360 generate a leadin move on those for ya?
02:21 PM perry_j1987: appears to
02:21 PM Tom_L: just checking :)
02:22 PM jym: f360 does CAM too?
02:22 PM Tom_L: yes
02:22 PM perry_j1987: if i choose climb it starts at top and goes down, if i choose conventional it starts at bottom and moves up
02:22 PM Tom_L: i'm told.
02:22 PM Tom_L: external you want to start at the top
02:22 PM Tom_L: internal at the bottom
02:23 PM Tom_L: i suppose i should revise my macro to accept metric
02:23 PM Tom_L: i'll likely never use it though
02:25 PM Rab: perry_j1987, Tom_L, do both of you have SmartCAM? Or how are you using the macro?
02:26 PM perry_j1987: i only have fusion360. i translate anything im told into it :P
02:30 PM Tom_L: Rab, you're using smartcam right?
02:35 PM Rab: Tom_L, I am not.
02:39 PM * JT-Shop made a little money last month :)
02:40 PM Tom_L: come out of retirement?
02:47 PM jym: Tom_L: The BIG blakc ants are carpenter ants, come out at night and nest in decaying wood commonly
02:48 PM jym: Tom_L: They dont seem to be going after the greasse or honey, even they that's what they are attracted to, still seeing if they'll take the bait in a day or two
02:53 PM Tom_L: feed em steak
02:53 PM jym: Tom_L: I did... it's hamburger grease
02:54 PM jym: with pieces of REAL meat =)
02:55 PM jym: Tom_L: Now, making more piss ant bait traps, they are starting to come out in full force. Found one on the counter in the kitchen this morning.
02:55 PM jym: It's jsut so hard to find the nest(s) much of ht etime
02:56 PM andypugh: Just accept them as pets.
02:56 PM Tom_L: i'll train mine to come visit
02:56 PM jym: andypugh: IF they accept napalm as me keeping them warm at night, sur e=)
02:57 PM andypugh: https://www.youtube.com/watch?v=MKx3JlTnHbc
02:57 PM jym: andypugh: But the bait traps I've been making are working =)
02:57 PM jym: andypugh: HAHAHAHAHAHA
02:58 PM jym: andypugh: Well, I have to register to buy the insecticide I use, blah blah blah, EPA federal goverment, blahb lbah blah
02:59 PM Tom_L: califor n i a , not the rest of us
02:59 PM jym: Tom_L: Nope, EPA, FEDERAL, not state
03:00 PM jym: Tom_L: It's solvents that I have to smuggle across the state border from Nevada
03:02 PM jym: Tom_L: Like REAL MEK, that fake substititue crap just doesn't work
03:03 PM jym: They don't even sell the fake crap anymore it's that bad.
03:03 PM Tom_L: they still make MEK?
03:03 PM Tom_L: i thought that was one they discontinued
03:03 PM jym: Sure, banned in California
03:04 PM Tom_L: what do you need MEK for?
03:04 PM jym: solvent welding acrylic
03:04 PM Tom_L: mmm i just use the solvent from the can. never looked to see what was in it
03:05 PM jym: I use pure MEK
03:06 PM jym: Tom_L: this is for capilary action, like the seemless welding on fish tanks
03:06 PM Tom_L: i know
03:06 PM Tom_L: mine is liquid too
03:07 PM Tom_L: i got a tube of the paste but didn't like it
03:07 PM jym: gelled is for other stuff
03:07 PM Tom_L: i know
03:07 PM Tom_L: filling gaps
03:12 PM perry_j1987: ok i need a little bit of handholding :P
03:12 PM perry_j1987: i have this spindle that cant go too low in rpm
03:12 PM perry_j1987: so im always confused trying to figure out speeds and feeds
03:13 PM perry_j1987: vs charts or calculators i come across
03:13 PM andypugh: I have this spindle that can’t go above 1000rpm. Both are sub-optimal.
03:14 PM perry_j1987: mine doesnt have much torque below 6k
03:15 PM perry_j1987: how do you account for the limiations when figuring speeds and feeds?
03:15 PM perry_j1987: i dont have a very good grasp on the whole concept yet
03:15 PM andypugh: Now, torque I have :-) How’s this for low-speed spindle torque? https://www.youtube.com/watch?v=thtDRjgbxRE
03:15 PM Tom_L: i bet andy's is all torque below 1k rpm
03:16 PM Tom_L: perry_j1987 calculate based on chip load
03:18 PM andypugh: I use the FSwizard app, which I thought had a minimum spindle speed override, but I was wrong (I have only ever needed the maximum override)
03:18 PM perry_j1987: so im free to move numbers around as long as chipload stays acording to the chart?
03:19 PM Deejay: gn8
03:20 PM Tom_L: what size thread are you milling?
03:21 PM perry_j1987: was working on the speeds/fees for this 1/2" endmill for creating the boss
03:22 PM Tom_L: on my little mill i try to stay around .001" chipload per tooth or less in aluminum
03:23 PM Tom_L: the ones my kids run at their work is a whole different story: 33k rpm 174 hp spindles on some of them
03:25 PM perry_j1987: do they ever bring them home for you to play with on the weekends? :P
03:25 PM Tom_L: 2.2k ipm rapids
03:25 PM Tom_L: i wish
03:26 PM perry_j1987: heh they wake up a few minutes earlier and find you in their closet trying on their clothes to sneek into their job :P
03:27 PM perry_j1987: you just stare at them like deer in headlights for an awkward amount of time as your stepping into one of the pant legs
03:28 PM Rab: A surprisingly involved and personal fantasy.
03:28 PM perry_j1987: lol
03:28 PM perry_j1987: some people would go to great lengths to play with some real machines i supose
03:30 PM Tom_L: i used to
03:30 PM Tom_L: not that real though, the ones i ran were smaller
03:32 PM perry_j1987: ok think i got some gcode ready for a try
03:32 PM perry_j1987: about ready to cut a piece and get it in the vise
03:32 PM Tom_L: cut some butter the first time
03:34 PM perry_j1987: aye was going to try something soft first
03:45 PM andypugh: perry_j1987: https://www.instructables.com/id/Machinable-Wax/
03:45 PM andypugh: (Cheapest source of paraffin wax is Ikea candles)
03:46 PM andypugh: In fact you can just machine candles: https://www.youtube.com/watch?v=7swEpeDI36g
03:47 PM XXCoder: isnt it easily castable?
03:47 PM XXCoder: but flammable?
03:47 PM XXCoder: paraffin cam lol
03:48 PM perry_j1987: interesting
03:48 PM andypugh: The blog post about that was called “Cams without CAM”
03:54 PM jym: XXCoder: wax metls around 165F on average depending on the wax formulation.
03:54 PM XXCoder: not bad
03:54 PM SpeedEvil: http://www.perthmint.com/1-tonne-gold-coin.aspx - neat.
03:54 PM jym: XXCoder: you CAN even melt max using boiling water
03:55 PM XXCoder: isnt that huge coin got stolen?
03:56 PM XXCoder: oh different giant coin
03:56 PM XXCoder: https://www.reuters.com/article/us-germany-trial-coin-theft/four-men-go-on-trial-for-theft-of-giant-gold-coin-from-berlin-museum-idUSKCN1P41KM
04:38 PM jym: I'm sorry, this stove just looks WAY TOO SMALL even if it's a a portable wood stove... https://youtu.be/yXzfnCmhqus?t=1808
04:43 PM andypugh: Kind of funny that both coins had the head of the same old woman on them.:-)
04:44 PM jym: lol
04:45 PM CaptHindsight: jym: dats whyits portable
04:46 PM jym: CaptHindsight: So is this, but I can but cord sozed wood in it... https://www.sportsmansguide.com/product/index/guide-gear-outdoor-wood-stove?a=1884248
04:46 PM jym: CaptHindsight: and much bigger "shelf" for my cast iron skillet, and coffee =)
04:47 PM jym: MUST HAVE COFFEE =)
04:47 PM CaptHindsight: jym: just wheels and drive train
04:47 PM jym: CaptHindsight: ?
04:47 PM CaptHindsight: jym: I just eat from tubes and bottles when camping
04:47 PM gregcnc: i'd be pretty upset if that coin fell out of my pocket
04:47 PM CaptHindsight: jym: just add ^^
04:48 PM CaptHindsight: 100Kg
04:49 PM jym: CaptHindsight: lol... bottled beef... yum! NOT!!!
04:49 PM CaptHindsight: pizza juice
04:49 PM jym: CaptHindsight: There is nothing better than MEAT... ON A STICK!!!
04:49 PM jym: CaptHindsight: Bacon wrapped bacon on a stick cooked over an open fire
04:50 PM CaptHindsight: jym: how about a nuclear reactor in a soda can?
04:50 PM jym: CaptHindsight: Nope, meat on a stick beats 99.9999% of everything else
04:51 PM CaptHindsight: if you could choose between an endless supply of water or power (but is under 5Kg) while camping, which would you choose?
04:52 PM CaptHindsight: a device that pulls water out of any of it's surroundings (including you)
04:52 PM jym: 5kg of power???
04:52 PM CaptHindsight: yes, the weight of the device is <5Kg but say outputs 500W indefinitely
04:53 PM gregcnc: foreverever?
04:53 PM CaptHindsight: or a device that is under 5Kg that provide endless clean water
04:53 PM jym: Hmmm, let me think...
04:53 PM CaptHindsight: gregcnc: yes, for 1000 years or until you die, whichever comes first
04:53 PM jym: CaptHindsight: where am I?
04:54 PM CaptHindsight: jym: you are camping
04:54 PM CaptHindsight: on earth
04:54 PM jym: but where?
04:54 PM jym: anywhere?
04:54 PM CaptHindsight: Texas or somewhere really bad
04:54 PM jym: 500W tesla gun???? eh
04:55 PM Rab: "Black oxide coating, combined with an oil film, does little more than enhance the appearance of carbon steel fasteners. The oil film is the only part of the coating that prevents corrosion." Stone cold schooling by the NASA Fastener Design Manual.
04:55 PM CaptHindsight: yup
04:55 PM Rab: https://ntrs.nasa.gov/search.jsp?R=19900009424
04:55 PM jym: I could sell the water...
04:55 PM jym: or barter
04:55 PM CaptHindsight: jym: yes or the power
05:03 PM jym: CaptHindsight: But I'f I'm in the Mojave, 500W AC not not gonna cut it
05:03 PM roycroft: the black oxide coating has a tiny effect on preventing corrosion
05:03 PM roycroft: but it's hard to overstate how tiny that effect is
05:03 PM jym: CaptHindsight: a swamp cooler with water to spare is a good thing
05:04 PM jym: CaptHindsight: I would do the water, even as tempting the power is
05:07 PM jym: CaptHindsight: Now, if I know a way to use the 500W to EXTRACT lots water form the atmosphere, that might be different
05:37 PM perry_j1987: ok this is weird
05:37 PM perry_j1987: i tell it g0 x0 y0 and it goes to x11
05:37 PM perry_j1987: it says x11 on the dro too
05:37 PM perry_j1987: manually jog over to x0 area and then for giggles put in g0 x0 again and it moves up to x11
05:38 PM perry_j1987: what gives
05:38 PM jthornton: do you have any offsets in effect?
05:40 PM Tom_L: is g90 or g91 in effect?
05:43 PM CaptHindsight: TIG welding SS with nitrogen vs argon
05:44 PM andypugh: CaptHindsight: ?
05:44 PM jym: CaptHindsight: what does the argon add that nitrogen doesn't offer?
05:45 PM andypugh: https://en.wikipedia.org/wiki/Nitriding
05:46 PM andypugh: Nitride hardening relies on reacting nitrogen with Chromium. All stainless contains a lot pf chromium [citation needed]. Ergo TIG welding stainless with nitrogen is a terrible idea. Discuss.
05:46 PM jym: CaptHindsight: https://www.bakersgas.com/weldmyworld/2011/05/09/shielding-gases-used-in-welding/
05:47 PM jym: Nitrogen increases weld penetration and enhances arc stability. It is used for some stainless steels, but will cause porosity in carbon steels. Pure nitrogen, hydrogen-nitrogen, or argon-carbon dioxide-nitrogen may be used. When using an alloy containing nitrogen, nitrogen gas blends will increase mechanical properties, resist pitting corrosion, and prevent loss of nitrogen from the metal. It can be used in some laser welding.
05:48 PM andypugh: perry_j1987: Is your DRO showing work coordinates or machine coordinates?
05:50 PM perry_j1987: let me check
05:50 PM CaptHindsight: jym: in my case 60 minutes of argon in a can vs 600 minutes of nitrogen in a can on hand :)
05:50 PM andypugh: jym: But not many stainless steels contain much nitrogen, 2 seconds on Google allows me to state authoritatively (and maybe wrongly) that it is only the Martensitic ones.
05:50 PM perry_j1987: i see g90 and g91.1 listed in active gcodes
05:50 PM andypugh: perry_j1987: This is a GUI setting
05:51 PM perry_j1987: where do i check
05:51 PM jym: andypugh: I was just quoting from that link, which also state for other gasses too
05:51 PM CaptHindsight: andypugh: there's also some discussion of nitrogen breaking down the tungsten electrodes so that it also gets into the SS
05:52 PM jym: CaptHindsight: is the nitrogen working? is argon working better?
05:52 PM andypugh: perry_j1987: Which GUI?
05:53 PM CaptHindsight: jym: I use Argon, but i realized that if I need to weld more before Monday could i use the nitrogen I have on hand
05:54 PM perry_j1987: the default one
05:54 PM Tom_L: if you tell it to go G91 G1 x0,y0,z0 it will go nowhere but if you tell it to G90 G1 x0,y0,z0 it may move
05:54 PM jym: andypugh: I'm sure that if nitrogen was the perfect welding gas, eveyone would have nitrogen concentrators attached to tho their welders =)
05:54 PM jym: CaptHindsight: ah ok
05:54 PM perry_j1987: ok testing
05:55 PM CaptHindsight: many industrial suppliers are closed from now until monday am
05:55 PM Tom_L: depending where it currently sits
05:55 PM Tom_L: CaptHindsight take a hint :)
05:56 PM andypugh: perry_j1987: Probably Axis?
05:57 PM CaptHindsight: 22 ga 304 SS sheet
05:57 PM CaptHindsight: looks like i could
05:57 PM andypugh: View-> Show Machine Posiiton or Show relative position. You want the second.
05:59 PM CaptHindsight: https://www.cnn.com/2019/07/03/entertainment/arte-johnson-obit/index.html
06:00 PM CaptHindsight: Ruth Buzzi is still kicking!
06:01 PM perry_j1987: ok I shut axis down and opened it back up
06:02 PM perry_j1987: and the g59 offset i was using all of sudden showed x0y0 when homed instead of the offset it was suppose to have
06:02 PM perry_j1987: just reset it up and now its working
06:02 PM perry_j1987: so weird
06:02 PM andypugh: This isn’t Windows. That isn’t the panacea
06:07 PM JT-Shop2: did you change back to g59?
06:12 PM perry_j1987: ya i had to resetup g59 when i reopened axis
06:12 PM perry_j1987: after i homed the machine and flipped over to g59 it shoed 0.0 for coords
06:13 PM andypugh: If you have Emoji in the DRO then something is wrong :-)
06:14 PM andypugh: (though that might depend on your IRC client)
06:15 PM andypugh: perry_j1987: https://imagebin.ca/v/4mm1o8D48AB0
06:20 PM perry_j1987: lol
06:23 PM perry_j1987: ok oddness again
06:23 PM perry_j1987: homed the machine switched to g59
06:24 PM jthornton: what gui are you using?
06:24 PM perry_j1987: and mdi told it to do g0 x0 y0
06:24 PM perry_j1987: axis
06:24 PM perry_j1987: and it doesnt move
06:24 PM jthornton: ok
06:24 PM jthornton: what does the dro read after homing then switching to g59?
06:24 PM perry_j1987: it is set to show relative position in the gui
06:24 PM perry_j1987: it shows neg x and y as you would expect
06:25 PM jthornton: x0 and y0?
06:25 PM perry_j1987: no if i home it is neg x and y showing
06:26 PM perry_j1987: just zeroing g59 and reset it up again
06:31 PM andypugh: If you are in G91(?) then G0 X0 Y0 means “ do not move"
06:31 PM jthornton: good point
06:32 PM _unreal_: its so nice to have my cnc machine working finally
06:32 PM jthornton: come fix my truck now that your free
06:34 PM perry_j1987: ok there is gremlin
06:34 PM perry_j1987: i just went and touched off on x and y then went up in z to clear everything
06:35 PM perry_j1987: and told it to go half the distance in x,y to center on the corner
06:35 PM perry_j1987: it moves the right amount in y but x is 3.1mm off
06:36 PM Tom_L: what are the active gcodes?
06:37 PM andypugh: and is that 3.1mm in the real word or in the DRO?
06:38 PM perry_j1987: the dro shows its off and real world it appears to be off same amount
06:38 PM Tom_L: when i mdi a move i always specify G91 so it will move the distance on the mdi line
06:39 PM Tom_L: not distance from the preset x0 y0 z0
06:39 PM perry_j1987: i've never had it do this to me before
06:39 PM perry_j1987: on side note
06:39 PM perry_j1987: threadmills z point
06:40 PM Tom_L: also, did you accidentally set an X or Y value when touching the tool off?
06:40 PM perry_j1987: is it touched off on end of thread mill or do i line up the point of it for z
06:40 PM perry_j1987: no i verifyed it was 0,0
06:40 PM Tom_L: i've had the checkbox on the wrong axis sometimes and had to clear the tool table
06:40 PM Tom_L: where you touch off the threadmill depends on your cad cam. i touch off the end of the tool
06:41 PM Tom_L: then it will never decide to go .050" or so into a place it can't
06:42 PM jthornton: yea having the wrong checkbox checked has caught me a few times in axis
06:43 PM Tom_L: and i have gui buttons for that too but i never use em
06:44 PM jthornton: on my lathe I set up buttons to touch off tools to a fixture (the spindle face) and to touch off to the material
06:45 PM perry_j1987: i think what i need to do is offer free pizza and beer to someone local enough to come on over and give me a rundown on things haha
06:46 PM jthornton: do you have teamviewer installed?
06:46 PM andypugh: Where are you?
06:46 PM jthornton: free pizza and beer is mighty attractive lol
06:46 PM Tom_L: andy lives to travel :)
06:46 PM perry_j1987: heh
06:47 PM perry_j1987: damn now i made myself hungry
06:47 PM andypugh: I think we are in the same country?
06:48 PM andypugh: Ah, maybe not
06:48 PM jthornton: Andy was warming up his motorbike...
06:49 PM andypugh: Today at work, a supervisor from another team wandered round with “err, do any of you want to go to China for a month?”
06:49 PM jthornton: are you talking to me?
06:49 PM jthornton: lol
06:52 PM Tom_L: warming up his ner-a-car?
06:53 PM jthornton: yea I suspect is is a bit slow but gets you there eventually
06:53 PM andypugh: I meant to go to work on the motorpike today, but it failed to start. On reflection it hasn’t moved for about 2 weeks, I have been cycling to work and using test cars at weekends.
06:53 PM andypugh: And the alarm kills it.
06:54 PM Tom_L: did you get your new bicycle assembled?
06:54 PM andypugh: Not a problem for the ner-a-car, but that is currenlty suffering from a weak magneto
06:54 PM andypugh: Yes, the new bicycle is my main transport :-)
06:55 PM * jthornton walks to work...
06:55 PM jthornton: it's not that far from the house to the shop
06:55 PM Tom_L: there _is_ the chicken distraction along the way...
06:56 PM andypugh: https://photos.app.goo.gl/jRUt1rXC39rGLQ5r9
06:56 PM Tom_L: nice bike
06:56 PM jym: andypugh: China for a month, is that with a $100/day allotment ?
06:57 PM jthornton: actually there is a raised bed planter on the way that need inspection
06:57 PM andypugh: No, thats on normal pay + receipted expenses
06:57 PM jthornton: andypugh: that's nice
06:57 PM jym: andypugh: how much are you allow for food a day?
06:57 PM jym: jthornton: got your truck back togetherR
06:57 PM jthornton: is it lighter than the last one enough to notice?
06:57 PM jthornton: no got it apart lol
06:58 PM jthornton: bed is hanging from the gantry now
06:58 PM andypugh: jthornton: I am not sure, but it is faster
06:58 PM andypugh: It’s not super light (despite being mainly carbon)
06:58 PM Tom_L: bigger engine?
06:58 PM Tom_L: :)
06:59 PM jthornton: https://matrix.org/_matrix/media/v1/download/matrix.org/EBnIWZgajtAedCBsmiXvKGOi
06:59 PM andypugh: 19.5 lbs in your quaint units
06:59 PM jym: andypugh: Sad;y, the street food vendors dont give receipts =)
06:59 PM jthornton: nice only weighs 1.392857 stone
07:00 PM jym: jthornton: how many bussheels of grain is that?
07:00 PM jthornton: I was very surprised how much lighter my road bike is compared to the mountain bike
07:00 PM andypugh: That photo was meant to show that you can see straight through the crak.
07:00 PM jthornton: I don't think there is an exact conversion first you must convert to cubits
07:01 PM andypugh: (crank)
07:01 PM jthornton: a bit of white behind might help
07:01 PM jym: jthornton: Ah, gotacha
07:02 PM jthornton: andypugh: how do you adjust the seat height?
07:02 PM jym: andypugh: That bicycle looks like it cost a house payment or two or three
07:03 PM andypugh: the crank is this: https://www.youtube.com/watch?v=NyxCengPUbM Cyclists appear to be unconvinced, but as an engineer I really admire it https://www.youtube.com/watch?v=NyxCengPUbM
07:04 PM Tom_L: if you zoom in enough you can see thru it to the wood
07:05 PM andypugh: jym: Well, I reckon I spent about £1400 and that’s only slightly more than a ready made bike. And I got the fun of the build.
07:06 PM Tom_L: so from the video i gather the cranks can be moved off 180 deg from each other for whatever reason
07:06 PM Tom_L: the way the 'spline' appears anyway
07:07 PM jym: jthornton: YOu are getting all kinds of use out of the gantry you built =)
07:08 PM jym: jthornton: Since the bed is off, just turn it into a dump bed =)
07:08 PM jthornton: from time to time yes, quite handy when I need a crane
07:08 PM Tom_L: or just an excuse to use it :)
07:08 PM jym: What Tom_L said =)
07:08 PM jym: Glorified erector set
07:09 PM jym: andypugh: I suppose not that bad then
07:09 PM jthornton: well it did make the job of getting the bed of rather simple
07:10 PM andypugh: Tom, there are several ways to mis-assemble. That’s not the point. The point is that the cranks join at the middle, so can be very narrow at crank to shaft inerface. And keeping your feet close together is good (Q factor, they call it)
07:10 PM Tom_L: yeah, it was just an observation
07:10 PM jthornton: andypugh: how do you adjust the seat height?
07:11 PM andypugh: jym: https://www.evanscycles.com/cannondale-synapse-carbon-disc-ultegra-2019-road-bike-EV338183
07:11 PM andypugh: Identical spec
07:12 PM andypugh: jthornton: There is a neat wedge-clamp for the seat post
07:12 PM jym: andypugh: doens't even come with peddles! lol
07:12 PM jthornton: like the goose neck wedge? or cooler
07:13 PM andypugh: jthornton: One of the pics here shows it: https://www.ebay.co.uk/itm//263933895492
07:15 PM jthornton: ah yea very cool indeed
07:15 PM jthornton: the more force from sitting the tighter it gets... very clever
07:15 PM jym: https://i.ebayimg.com/images/g/i9gAAOSwMrJc8Jup/s-l500.jpg
07:17 PM jthornton: all right I hear the rabbit food being prepared for dinner
07:21 PM * jym sneaks jthornton meat on a stick
07:23 PM jym: CaptHindsight: I'm thinking mounting a 6" 12VDC fan in a 4ft section of pipe and tossing it in the river to see what it can do
07:26 PM Tom_L: rust?
07:26 PM jym: Tom_L: thin wall pvc pipe, about 4 or 6 in diam
07:28 PM Tom_L: cnc a turbine
07:30 PM jym: Tom_L: https://www.youtube.com/watch?v=cHxHLqZAD-w
07:30 PM jym: I need to find the other video
07:31 PM jym: closer... https://youtu.be/JfdlG5hVUhs?t=35
07:34 PM jym: Tom_L: Ah, here you go... https://www.youtube.com/watch?v=0ieFZI4-6K8
07:35 PM jym: Tom_L: westinghouse and whirpool use the same motor
07:35 PM Tom_L: yeah i just put bearings in mine
07:36 PM jym: Tom_L: Hi the back of appliance stores, they have to pay to have the old ones hauled away
07:42 PM andypugh: jym: Then see how much better it works without the pipe
07:43 PM _unreal_: DONE..... its FREAKING DONE!!! just finished tapping all 130 some odd 6-32 holes
07:43 PM _unreal_: only broke 2 taps
07:43 PM _unreal_: amazingly
07:43 PM _unreal_: one by being stupid the other I just dont undrstand the tap got stuck in a a hole that it had no reason to AT ALL
07:44 PM andypugh: You can run those motors with a mesa 8i20: https://www.youtube.com/watch?v=2HdikHRXnAs
07:44 PM _unreal_: the one I was stupid on I forgot that there was ONE hole I didnt drill all the way threw and I jammed the tap :)
07:44 PM _unreal_: :(
07:45 PM _unreal_: BUT now that i have all my holes drilled I can now mount stuff for milling :)
07:45 PM _unreal_: I do need to deburr the holes but thats the least of my issues
07:45 PM Tom_L: andypugh probably not the best spindle motor candidate
07:46 PM jym: andypugh: Not sure how I would keep the fan vertical without the pipe
07:46 PM Rab: andypugh, 3-phase BLDC motor?
07:46 PM Rab: andypugh, do you have the part number? Might be a good addition to the description.
07:47 PM Rab: Oh, just read the comments.
07:47 PM andypugh: Rab: No, I found it cheap in eBay
07:48 PM Rab: I have a couple of large (3/4HP) 3-phase motors from HVAC systems. The integrated controllers tend to die, and then the motors are effectively useless.
07:49 PM andypugh: Well, LinuxCNC has several possible replacements.
07:49 PM andypugh: 8i20, 7i39, STMBL, Granite, AMC…
07:52 PM Rab: andypugh, any status updates on STMBL since the business end went EOL?
08:02 PM andypugh: Rab: From https://gitter.im/rene-dev/stmbl Nico Stute @crinq Jun 01 08:35
08:02 PM andypugh: next version will use a discrete powerstage
08:02 PM andypugh: prototype is done, just needs a lot of testing
08:06 PM _unreal_: I can get free BLDC motors every now and then
08:06 PM _unreal_: big one's to nema 24
08:09 PM andypugh: You mean small ones
08:09 PM andypugh: ?
08:11 PM andypugh: I have this mid-sized one: https://photos.app.goo.gl/FxGcbdMgHVjLsa9x7
08:16 PM CaptHindsight: I still use Parker and AB drives
08:17 PM CaptHindsight: https://www.ebay.com/itm/FESTO-MINI-SLIDE-EGSL-BS-55-200-12-7P-WITH-ALLEN-BRADLEY-VPL-B0631U-PK14AA/253990227211
08:18 PM CaptHindsight: don't think STMBL went up to 480V
08:18 PM CaptHindsight: 200 something IIRC was max
08:20 PM andypugh: STMBL is OK to 320 definitely, I think that the IRAM was a 600V part, technically.
08:21 PM CaptHindsight: what opens EESchema Schematic File Version 4? kicad or something
08:21 PM andypugh: rene_dev_: Can you confirm or deny?
08:22 PM andypugh: STMBL is done in KiCAD
08:23 PM CaptHindsight: i think I have that viewer
08:46 PM Valen: Setting up a new system, debian buster (10) a terrible idea? It's going to be out of my touch for quite a while so I'd like something that'll last a while
08:46 PM Valen: thinking preempt-rt with mesa
08:51 PM Tom_L: sounds like they may be real close for RTAI
08:52 PM Valen: I have another friend looking to update his pport stepper to something that can run chrome and that'd make him very happy
08:52 PM andypugh: Bustrer and an off-the-shelf preempt-rt kernel might well work (you would have to compile your own LinuxCNC)
08:53 PM andypugh: I have a 4.14.131 RTAI kernel biut not yet an RTAI .deb
08:53 PM Valen: compiling linux cnc is preferable to a kernel compile for me/them ;-)
08:53 PM Valen: oh you got rtai working? that's great it sounded like a lost cause before
08:54 PM andypugh: I suggest installing Buster, then going to Synaptic and searching for linux-image and seeing if there is a preempt-rt kernel there
08:54 PM SpeedEvil is now known as Guest87351
08:54 PM jym: Valen: Is he gonna watch videos on it too? Why not get a desktop pc/laptop and a cnc pc
08:54 PM Valen: yeah I'll give that a go
08:54 PM Valen: https://packages.debian.org/search?keywords=linux-image-rt seems to indicate buster has rt
08:55 PM andypugh: Yes, looks good
08:55 PM Valen: jym: he wants to use "cloud" to move his cam files around and do internet stuff
08:55 PM jym: Valen: no comment =)
08:55 PM Valen: He had been doing it for years but everybody has depreciated their old software so nothing works any more
08:56 PM andypugh: I don’t know for sure that LinuxCNC compiles against that, but if it doesn’t then that’s a high-priority fix.
08:56 PM norias: hello
08:56 PM Valen: I'll give it a go and let you know how it goes
08:56 PM Valen: haven't installed debian in years lol
08:56 PM andypugh: norias: Hi
08:56 PM Valen: going to do a raid install just for the giggles
08:56 PM Elmo40: it is only the best distro out there!
08:56 PM jym: Valen: why debian?
08:56 PM Valen: (sw raid)
08:57 PM norias: andypugh: how are you?
08:57 PM andypugh: Mainly up too late on a work night :-)
08:57 PM norias: non-US?
08:57 PM Valen: seems to be the best for long term stability and seems popular around linuxcnc. I use ubuntu by default but I'm over gnome 3 and xfce feels like a poor cousin there
08:57 PM andypugh: UK. 3am here
08:58 PM jym: Valen: I a using ubuntu-mate distro and Ilike it
08:58 PM norias: tomorrow we celebrate being non-UK, here
08:58 PM norias: well, some people have already started celebrating
08:58 PM norias: like my freakin neighbors
08:58 PM jym: Valen: https://ubuntu-mate.org/
08:58 PM Valen: Might go debian with mate, guess I've got the horsepower to do it
08:59 PM andypugh: Yes. We3 were not too impressed over here, it seems, by the taunting of your football team when it beat ours.
08:59 PM jym: andypugh: butthurt are we?
09:00 PM norias: andypugh: i'm not familiar with all that. i don't really follow sports
09:00 PM Valen: who the hell thought getting rid of typeahead was a good idea, gnome 3 you are doing the dumb, don't dumb here, this is a no dumb zone
09:00 PM jym: andypugh: brazillian is much worse
09:00 PM Valen: andypugh: think the rtai will keep somewhat up to date with kernel releases?
09:00 PM andypugh: Personally I don’t really care. But note that historically speaking the Empire seems to have spent more time worrying about accidentally expanding than about contracting.
09:01 PM norias: andypugh: fair. it was a pretty big empire. i think it was at it's biggest under Queen Victoria, right?
09:02 PM andypugh: Your revolutionary war was pretty much a side show (once France joined in) of the Napoleonic wars where the UK was trying to avoid being invaded by France. I know it is super-important to you, but, to us, it was a long time ago.
09:03 PM Valen: The phrase "the sun never sets on the empire" was for a while literally true
09:03 PM andypugh: It’s actually still true
09:03 PM andypugh: Only just.
09:03 PM norias: andypugh: well, i think that our victory was in great part due to the monarchy's lack of concern
09:04 PM Rab: It's super-important to me because I don't work tomorrow!
09:04 PM andypugh: https://what-if.xkcd.com/48/
09:04 PM norias: George Washington was amazing at running away at exactly the right time in an orderly fashion.
09:05 PM andypugh: norias: Indeed, the colonies were not founded as any sort of government policy, more a lot of UK nationals went somewhere and were still british.
09:06 PM norias: I, personally, find that whole period kind of fascinating and instructive
09:06 PM andypugh: Whereas India (far more valuable and important) was accidentally conquered by the East India Company.
09:06 PM norias: my overview is that a bunch of rich guys figured they'd go for it
09:07 PM norias: convinced the poor guys to grab their guns
09:07 PM andypugh: Rich gits.
09:07 PM norias: and the empire shrugged long enough that it worked
09:07 PM andypugh: Clive of India was a horrible man
09:08 PM norias: i haven't read that much of English history to know him by name
09:08 PM andypugh: I am guiessing Penn wasn’t that nice. (Pannsyvania) Ditto Cecil Rgodes (Rhodesia). You don’t get to call part of the world bigger than your home island after yourself by being a nice chap.
09:09 PM norias: heh
09:09 PM norias: I live in Pennsylvania, btw
09:10 PM _unreal_: any one know of a link to some good tie down gcode that I could use for my mill?
09:10 PM norias: _unreal_: tie down?
09:10 PM jym: duct tape?
09:10 PM _unreal_: I need to mill out some crescent shaped hold downs that I can use with the screws
09:11 PM jym: _unreal_: have you seen a mounting set?
09:11 PM _unreal_: a tie down that uses aluminum or poly. kind of like using a washer with a screw
09:11 PM _unreal_: not really
09:11 PM _unreal_: and I'm not about to purchase one when I have a ton of STARBOARD on hand
09:12 PM andypugh: norias: https://www.amazon.com/gp/product/B00AR2RZJ0/ref=dbs_a_def_rwt_bibl_vppi_i0
09:12 PM _unreal_: I'd love to make some mounting clamp adapters with it
09:12 PM jym: _unreal_: https://www.harborfreight.com/42-piece-machinist-clamping-kit-90752.html
09:13 PM norias: jym: ugh.
09:13 PM norias: i'd say "welcome to 1964"
09:13 PM norias: but my dayjob largely consists of running a Bridgeport made in 1964
09:13 PM norias: so, whatever
09:14 PM _unreal_: jym, nice set but way over what I need
09:14 PM _unreal_: My cnc machine is not that big
09:14 PM andypugh: norias: Rather funny, well written. The main character is horrible (and meant to be) but the historical situations he is put in are reall well researched and written. I think he might well be an accurate portrayal of a true Victorian hero. Nasty, selfish and lucky to be on the right side at the right time.
09:14 PM jym: _unreal_: Yes, I know, but might give you some ideasss
09:14 PM norias: andypugh: lol
09:15 PM andypugh: They really are a great read.
09:16 PM norias: andypugh: i think my next great read will be the RS274NGC interpreter code. :|
09:16 PM _unreal_: These are interesting https://www.myerswoodshop.com/blog/clamps
09:17 PM _unreal_: but they are rotation not top down
09:17 PM _unreal_: jym, thanks
09:18 PM andypugh: He spends a fair amount of time in the US. Because he is a fictional character he manages to be at Little Bighorn (on the winning side) and the raid on the Harpers Ferry Aresenal.
09:19 PM jym: _unreal_: Just giving you ideas of what's out there... https://www.rockler.com/universal-t-track-universal-t-track
09:19 PM andypugh: (and both Traflagar and Warterloo, if I recall correctly)
09:20 PM jym: _unreal_: https://www.rockler.com/48-universal-t-track-with-hold-down-clamps
09:23 PM jym: _unreal_: maybe a better example of how it can be used, there are different sizes too.... https://wac.edgecastcdn.net/001A39/prod/media/6f2iIJdfiy1XrhEsite/246B61F53FF4829C04AA864DDDB3AA3C.app1_1511030768527_L1800.jpeg
09:25 PM _unreal_: looking
09:26 PM Rab: _unreal_, I saw these a while back and thought they were neat for light duty. I believe they are made from stainless steel pipe: http://img.photobucket.com/albums/0803/jstanley/3x4table_fixtures.jpg
09:26 PM _unreal_: jym, that last photo link is more or less what I'm looking at making is something like that. I did come across years ago likely at this point. a site that had these nice designs
09:26 PM _unreal_: I may just rebuilt it from memory
09:27 PM _unreal_: Rab, Thats very close to what I was thinking
09:27 PM _unreal_: as I said I ahve a ton of starboard and 2" thick starboard. so I'll prob CUT some half inch or 3/4 strips put them on there side and cut out a shape(s) like that
09:28 PM _unreal_: Just converter this as well https://www.myerswoodshop.com/blog/clamps from C2D to svg
09:28 PM _unreal_: the idea behind them is you make them from MDF or what ever and they are "waste" clamps
09:28 PM _unreal_: easy to remill replacements
09:28 PM _unreal_: time for a drink
09:44 PM _unreal_: any one know what ever happend to fdarling?
09:44 PM _unreal_: or is there a BOT that can list the last time he was on?
09:44 PM _unreal_: have not been able to contact him at all wonering if he's ok/alive?
09:49 PM jym: _unreal_: Last seen : Jun 27 07:03:24 2019 (6d 19h 41m 23s ago)
09:55 PM _unreal_: hum
09:59 PM jym: _unreal_: you could also leave him a message... /msg memoserv send fdarling pay up sucker!!!
09:59 PM * _unreal_ ponders.... PAYUP...
09:59 PM _unreal_: heh
10:00 PM _unreal_: depending on my mood and desire to do shit.... I may start milling some of these tie downs
10:00 PM _unreal_: I picked up a bunch of screws and wing nuts
10:00 PM Valen: what distro are tormach using?
10:00 PM Valen: or have they rolled their own
10:00 PM _unreal_: granted my machine is tapped with 6-32 holes its not a big machine
10:01 PM _unreal_: I did a hole once an inch
10:01 PM _unreal_: working area aprox 7.5x12
10:01 PM _unreal_: more like 8x12
10:20 PM _unreal_: shhhh
