01:58 AM Deejay: moin
03:32 AM jthornton: morning
04:13 AM XXCoder: heys
04:22 AM jthornton: thought I heard chickens squawking at 3:30... woke me up fast... must have been dreaming lol
04:23 AM XXCoder: that or you dont have any left now ;)
04:28 AM jthornton: they are all there
04:29 AM XXCoder: yeah was likely they was fine lol
04:29 AM XXCoder: im sorta amazed to see there was small amount of flat area snow.
04:29 AM XXCoder: its under trees though so probably preserved
04:30 AM jthornton: our snow is long gone it's just wet out there
04:31 AM XXCoder: almost all jus piles here
04:31 AM XXCoder: slowly turning brown
04:32 AM jthornton: yea the coffee is ready
04:35 AM XXCoder: yay none for me thanks :)
04:38 AM jthornton: I need to figure out how to install windows xp and get by the phone home crap
05:03 AM jthornton: hmm I wonder if I make a backup from my xp laptop and install it on the hd in my pc that will work
05:03 AM XXCoder: why cant install directly on pc?
05:03 AM jthornton: it's such a pain you have a legal copy of windblows xp but can't install it
05:03 AM jthornton: you have to activate it
05:03 AM jthornton: and now xp down here is broken
05:04 AM XXCoder: bleh
05:04 AM jthornton: yea and I use acad 10 on xp for electrical drawings
05:04 AM XXCoder: https://www.wikihow.com/Make-Windows-XP-Genuine-Forever
05:05 AM jthornton: lol I have the genuine serial key
05:06 AM XXCoder: yeah but honestly xp is so old I doubt microsoft will knock your door, AND you have copy you can show them
05:06 AM XXCoder: if activation is issue that method just bypasses it outright.
05:07 AM XXCoder: it is also easy, basically delete registery key at right time then modify access right to that specific key root then done
05:07 AM jthornton: yea I'll try that, I tried a similar one before
05:07 AM XXCoder: using wrong words but whatever heh
05:07 AM jthornton: yep
05:15 AM Tom_L: morning
05:16 AM jthornton: morning
05:17 AM Tom_L: you should be able to swap xp out but will have to reinstall some drivers etc
05:17 AM Tom_L: i've done it a time or two but not the norm
05:18 AM jthornton: swap xp for what?
05:18 AM Tom_L: move from one pc to another
05:18 AM Tom_L: iirc i used ghost
05:19 AM jthornton: move from my laptop to the desktop? how?
05:19 AM Tom_L: oh, i'm not sure about that
05:19 AM jthornton: hmm I think I have a floppy with ghost on it
05:19 AM Tom_L: you could pull the hdd and get an adapter
05:19 AM Tom_L: i've done that then did a ghost copy on the pc
05:20 AM jthornton: I think I'll do a system image then try and install that
05:20 AM jthornton: or just install acad on the laptop and use it
05:21 AM jthornton: but what a pain to try and draw on a laptop
05:21 AM Tom_L: true
05:21 AM Tom_L: it's pain enough just to draw with acad
05:22 AM jthornton: I have an electrical add on that makes it easy to draw ladder diagrams of electrical circuits
05:22 AM jthornton: https://www.backyardchickens.com/attachments/photocell-door-jpg.1602456/
05:22 AM CNC_Brian: Morning Chaps
05:23 AM jthornton: that's one I made before xp puked
05:23 AM jthornton: morning
05:26 AM CNC_Brian: Im surprised you haven't got classic ladder running Chicken operations
05:26 AM jthornton: lol, I have a Raspberry Pi 3 b running the show
05:27 AM jthornton: speaking of chickens I think one just went into the nest box
05:28 AM CNC_Brian: You need a webcam.
05:28 AM Tom_L: he has an offline webcam i believe
05:29 AM jthornton: I have a nest box cam but it's on the egg collection side
05:29 AM jthornton: yea several
05:32 AM Tom_L: started on my external thread macro last night
05:32 AM CNC_Brian: Don't share the URL with me, I will never get any work done
05:32 AM Tom_L: may end up combining them eventually
05:33 AM Loetmichel: CNC_Brian: i had a "work webcam" in my last job... was kinda funny...
05:34 AM jthornton: https://imagebin.ca/v/4XmIa3uZxf1w
05:34 AM jthornton: that is before I put the lights in
05:37 AM CNC_Brian: Nice and clean in there.
05:38 AM jthornton: yea the false floor comes out for brushing off the tracked in dirt and crap
05:40 AM XXCoder: nice
05:42 AM CNC_Brian: Anyone seen a good design for a home-brew tool hight setter?
05:44 AM Loetmichel: CNC_Brian: timelapse of an exemplary day back then: http://www.cyrom.org/hajo/09_01_09.avi
05:45 AM jthornton: I use a dowel to set the Z of my tools
05:46 AM CNC_Brian: Yes that's what I do at the moment got a 20mm gauge pin
05:46 AM jthornton: new gimp for windblows is a bit strange but no more windows scattered all over the place lol
05:47 AM CNC_Brian: Got the probe sorted so tool setter is next before I Get a BT30 spindle then a ATC
05:47 AM XXCoder: heard it changed to mdi type
05:47 AM XXCoder: guess its true
05:47 AM CNC_Brian: Should keep me busy for a couple of years
05:47 AM jthornton: mdi?
05:48 AM jthornton: this is a photo from my run camera https://imagebin.ca/v/4XmMlW0f7pdX
05:48 AM XXCoder: not mdi in cnc terms, but programming. basically window with smaller windows inside it, or can move to sides etc and stick
05:55 AM jthornton: hmm it has tabs for each image now and doesn't have the focus problems it had in the past
06:10 AM CNC_Brian: Yes that more like I expected. If you could find a used for chicken poop you would be a rich man.
06:10 AM jthornton: I make compost with it
06:11 AM XXCoder: used lol
06:11 AM XXCoder: chickens crap is very rich soil enricher right?
06:12 AM jthornton: yea, I mix it with leaves in the winter and grass clippings in the summer
06:12 AM jthornton: I have a 3 station compost bin and the one with fresh poop stays covered up
06:13 AM XXCoder: would love composting to lessen garbage but too lazy
06:13 AM CNC_Brian: I have a little place in Spain and a neighbour covered his olive trees in chicken poop and kill them all.
06:13 AM XXCoder: plus neighbors would complain
06:14 AM XXCoder: ouch
06:14 AM jthornton: yea you can't use raw poop it's too hot lol
06:15 AM jthornton: a covered compost bin so they don't have anything to complain about lol
06:15 AM XXCoder: I need to get uncomposted horse crap. need to kill horsetails :( very hardy weed
07:11 AM XXCoder: jthornton: https://www.king5.com/article/weather/unusual-jet-stream-impacting-airline-operations-helps-explain-puget-sounds-weather/281-798abc5f-dcb2-49f9-a08a-e72a77a0e469
07:11 AM XXCoder: no wonder weathers been strange
07:13 AM jthornton: weird
07:15 AM XXCoder: yeah
07:16 AM XXCoder: sat have been upgraded to snow at evening and night
07:16 AM XXCoder: then clear but very cold later
07:17 AM XXCoder: funny because normally winter is just boring freezing for while, and not stay type of snow.
07:17 AM XXCoder: humans probably invented language to talk about weather. oh and danger commucation LOL
09:42 AM minicom: Hi! Not really related to this channel, but is there some IRC channel related to Siemens PLCs? I have a question but I couln't find an IRC channel for it
09:43 AM minicom: On the official Siemens forum I don't get any replies...
10:07 AM jdh: ask
10:42 AM hazzy-m: CNC_Brian: Last night I was looking shop made tool setters, but did not find much
10:42 AM hazzy-m: Did you make your probe?
10:43 AM gregcnc: anyone seen pinkvampire lately? She made a toolsetter
10:44 AM gregcnc: it was based on one of the probe designs
10:46 AM * hazzy-m wants to make a blum style probe
10:47 AM gregcnc: laser?
10:53 AM The_Ball: I'm creating a operator panel for my 3-axis mill, it has a touch panel running gmoccapy, but I like real buttons better, any tips on anything I've missed? https://imgur.com/a/K90lEQP
10:55 AM SpeedEvil: Is the big red button e-stop only?
11:01 AM The_Ball: SpeedEvil, yes, mushroom type
11:02 AM The_Ball: 3d -> https://imgur.com/a/bPK29HH
11:02 AM SpeedEvil: I would put it clear of the other controls on the bottom-right
11:03 AM The_Ball: I was taking the layout from haas' control panel where it's in the middle, what is your thinking for bottom-right?
11:04 AM SpeedEvil: To have it in a visually uncluttered space.
11:04 AM SpeedEvil: I guess it's not important really.
11:04 AM The_Ball: I haven't got much space to work with on this machine
11:05 AM SpeedEvil: ignore then. No particular compelling other reason
11:06 AM gregcnc: coolant?
11:07 AM The_Ball: The three yellow buttons are from the old control and have icons in them, chuck release, coolant and I don't remember the last one
11:07 AM fragalot: nobody remembers the last one
11:08 AM The_Ball: But I'm thinking of perhaps a rotary switch for coolant override-on / off / auto
11:26 AM CNC_Brian: Got an interesting issue here, just re-written my config from paraport to 7i76 and got some strange glitches with the steppers. Its almost like the ball screws are jamming momenterally
11:27 AM CNC_Brian: Could it be the hardware Stephen is just much faster and the stepper drives are missing steps?
11:27 AM CNC_Brian: stepgen
11:29 AM CNC_Brian: Everyone has gone to the pub:-(
11:29 AM gloops: no joint following error or anything?
11:30 AM CNC_Brian: Nope, but I have got the ferror set to .1 mm
11:31 AM CNC_Brian: min_ferror is .25
11:31 AM CNC_Brian: Not sure where I got these values from though soo long ago
11:32 AM CNC_Brian: My Stephen max accel somehow went up from 970 to 1500???
11:32 AM CNC_Brian: But it glitches mid way through a move, not at the beginning. Very strange
11:33 AM gloops: im a bit rusty with the basic config
11:34 AM CNC_Brian: Im also running a nice new qtpyvcp maybe my old PC is now too slow
11:35 AM CNC_Brian: Yes no problem, just though I would ask as Im sure its been seen before.
11:35 AM CNC_Brian: Cheers.
11:38 AM gloops: i had some issues with stepgen values when i set mine up, i cant remember what now
11:38 AM gloops: your ferror values are the default i think
11:41 AM gloops: stepgen.N.maxvel float rw
11:41 AM gloops: The maximum allowable velocity, in length units per second. If the requested maximum velocity cannot be reached with the current combination of scaling and make‚ąípulses thread period, it will be reset to the highest attainable value.
12:17 PM pcw_home: CNC_Brian: I would double the step times and see if the problem goes away
12:18 PM pcw_home: I see this _very_ often when people use a hardware step generator after having used a parallel port (step times too short)
12:19 PM pcw_home: if you tell a parallel port to generate a 1 usec step you may get 5 usec, if you tell a 5I25 to generate a 1 usec step you get 1 usec...
12:41 PM Jymmm: IF you tell a bear to generate a 1uS step, you'll get bitch slapped and eaten =)
12:46 PM rmu: CNC_Brian: if you don't have any feedback the ferror-values have nothing to do with the "real world", if unzero they are just some artefact of how stepgen and velocity planning works in linuxcnc
12:47 PM rmu: without feedback, you can disconnect the motors, and linuxcnc will behave exactly the same
12:50 PM ItsFlipp_: jthornton, Tom_L: Quick update from some tests last night to try and reduce the heat in the part
12:50 PM ItsFlipp_: upped chipload from 0.0027->0.0034, same SFM
12:51 PM ItsFlipp_: surface finish during roughing was *gorgeous*
12:51 PM ItsFlipp_: uuuuunfortunately didn't help the part. Superglue fixture failed in the same way
12:51 PM ItsFlipp_: upped again to 0.0043
12:51 PM ItsFlipp_: Surface finish still very, very good, but not quite as spectacular as 0.0034
12:51 PM ItsFlipp_: ... same failure
12:52 PM ItsFlipp_: Then I looked up the coolant I've been using
12:52 PM ItsFlipp_: Some generic stuff from Tormach, DuraKut 9000B
12:52 PM ItsFlipp_: Apaprently the flash point of it is 100C
12:53 PM ItsFlipp_: other coolants are apparently much higher (e.g. KoolMist is 180C according to MSDS)
12:53 PM ItsFlipp_: I'm beginning to wonder if the coolant is just ... bad
12:53 PM ItsFlipp_: We'll see tonight. Got some better stuff on the way
01:37 PM gregcnc: flood coolant?
01:37 PM gregcnc: flash point is irrelevant
01:37 PM gregcnc: itsflipp_^
01:38 PM gregcnc: if the part gets hot enough the glue will fail
01:39 PM methods_: yeah just use through spindle coolant
01:42 PM * Loetmichel is still at work(20:26 here)... underestimated how long those 2 19" enclosures will take to manufacture (AGAIN)... Problem: they HAVE to be at the pworder coating guy tomorrow at 07:00, or we will not get them back for monday delivery to the customer... ah well, only one more lid to go... 48 M3 threads, countersinks and screws in. then painters tape on taht stuff, and pack a box
01:42 PM * Loetmichel for the boss to bring it to the powder guy tomorrow... if i am lucky i can go home at 22:00... (startet 08:00 today)... :-(
01:46 PM Jymmm: powder? Nah, just toss on some hello kitty stickers and call it a day
01:50 PM fragalot: say it's clear coated
01:52 PM methods_: natural finish
01:55 PM gloops: get the heat resistant superglue - 150C
02:19 PM Loetmichel: fragalot: doesent look so good without paint
02:19 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14769
02:20 PM gregcnc: i wonder what this machine is for https://www.instagram.com/p/BuB45HzBeHF/
02:21 PM Loetmichel: will look like these switches when finished: blue front, rest black. http://www.cyrom.org/palbum/main.php?g2_itemId=17177
02:25 PM gloops: not many bolts in the sbr rails
02:29 PM gloops: so either theyre still in the post, or the machine isnt going to be doing any cutting
02:29 PM Jymmm: Loetmichel: https://www.amazon.com/Hello-Kitty-Stickers-4-Sheets/dp/B06XQNB1FB
02:29 PM ItsFlipp_: gregcnc: mist coolant
02:30 PM Jymmm: Loetmichel: better yet... https://www.amazon.com/Hello-Stickers-Sticker-Sheets-Designs/dp/B01CRC0TLS/
02:30 PM ItsFlipp_: gregcnc: sure, that's how my SG fixturing has failed so far
02:30 PM ItsFlipp_: I'm just trying to nail down exactly why the part is absorbing so much heat instead of the chips
02:33 PM gregcnc: how did you determine the chips aren't absorbing heat?
02:35 PM gregcnc: mist with neat oil or water based?
02:35 PM ItsFlipp_: Mist w/water based, I believe https://www.tormach.com/store/index.php?app=ecom&ns=prodshow&ref=37289
02:36 PM gregcnc: did you add water?
02:36 PM ItsFlipp_: I've done some similar ops before on a machine at work, and the part didn't get smoking hot :(
02:36 PM ItsFlipp_: no, it's premixed. "Use Neat"
02:37 PM ItsFlipp_: (I've got some KoolMist 77 on the way to test that)
02:37 PM gregcnc: no water in that, so minimal cooling
02:39 PM ItsFlipp_: MSDS suggests it's basically entirely Polybutene Copolymer
02:39 PM gregcnc: right
02:40 PM gregcnc: at work also mist coolant?
02:40 PM ItsFlipp_: Interesting. I was under the assumption that the majority of the cooling came from the fluid itself, whatever the composition
02:40 PM gregcnc: "coolant" is many things
02:41 PM ItsFlipp_: Work I've cut both flood and dry (no mister available there yet)
02:41 PM gregcnc: different types work in different ways
02:42 PM ItsFlipp_: Dry was less than ideal, but the part didn't actually get that hot
02:42 PM gregcnc: if you want to keep parts cool, flood is the way to go
02:42 PM gregcnc: same cutter?
02:42 PM ItsFlipp_: initially tried same HSS cutter, then tried a carbide
02:43 PM ItsFlipp_: I initially thought my S&F were a bit aggressive, but aside from the heat the surface finish and chip stream looked great
02:43 PM ItsFlipp_: 10kRPM@67 IPM, w/ 2 flute Carbide ZrN coating (translates to ~.0034 IPT and ~550-ish SFM)
02:45 PM ItsFlipp_: .45 DOC, .03125 WOC (~12% of diameter)
02:45 PM ItsFlipp_: that was the best surface finish, but I've also tried 10k@20, 10k@80, and 8.4k@31
02:45 PM ItsFlipp_: all ended up heating the part pretty good
02:46 PM gregcnc: what else is different when it works?
02:48 PM Loetmichel: Jymmm: i doubt the (military) customer would think thats funny.
02:48 PM ItsFlipp_: aside from different machine (slightly older model), that's what I'm tryin' to pin down :/
02:48 PM ItsFlipp_: my toolpaths are likely a bit different
02:48 PM gregcnc: part is the same?
02:49 PM ItsFlipp_: same part, same fixture style (sac plate->painters tape->Cyanoacrylate->painters tape->stock)
02:49 PM ItsFlipp_: does that 10k@67IPM cut sound wonky at all?
02:50 PM ItsFlipp_: still (relatively) new at dialing in S&F
02:58 PM gregcnc: aluminum?
02:58 PM ItsFlipp_: ya. 6061
02:59 PM gregcnc: essentially you can't go too fast in SFM, unless it's melting, or feed too hard unless you're breaking tools
03:01 PM Jymmm: Loetmichel: Hey, you never know
03:02 PM Jymmm: Loetmichel: Here we go... https://i.pinimg.com/originals/8e/46/37/8e4637b32b89ab64a83a05c59b356a35.jpg
03:03 PM gregcnc: i guess it's the tape adhesive that's failing not the superglue
03:04 PM ItsFlipp_: So far yes, that's pretty much what I've observed
03:04 PM ItsFlipp_: but is it normal for 6061 parts to get so hot the coolant basically boils off into a fog?
03:04 PM gregcnc: sure
03:05 PM gregcnc: either you had better tape at work or just got lucky a few times
03:06 PM ItsFlipp_: ha, true enough I guess
03:07 PM ItsFlipp_: so it's somewhat normal to have parts heat up to >100C during machining?
03:09 PM gregcnc: 100% of the spindle power ends up in the part and chips
03:10 PM gregcnc: it's hard to guess how much in each
03:10 PM ItsFlipp_: true
03:10 PM gregcnc: I guess some heat ends up in the cutter
03:11 PM ItsFlipp_: I guess myabe I'm just getting overconcerned that the part was getting hot enough during adaptive clearing ops to instantly vaporize coolant
03:11 PM ItsFlipp_: which in turn created a huge fog inside the machine
03:14 PM gregcnc: a different oil may smoke less. water soluble oil in the mister would aid in cooling
03:15 PM ItsFlipp_: sounds good, thanks. I'll try that
03:15 PM gregcnc: I'm going to try soluble oil in my mister. I'm running some kind of oil and it turns into the nastiest glue over time
03:16 PM ItsFlipp_: have some KoolMist 77 on the way; ya cut it something like 1:20 with water
03:25 PM ItsFlipp_: Yeah, we had the same problem at work with the flood coolant
03:25 PM ItsFlipp_: the coolant is in an open-ish tank, and the water would end up evaporating over time
03:25 PM ItsFlipp_: and after a while the coolant got more and more concentrated, which began leaving a stickier and stickier mess inside the machine
03:27 PM JT-Shop: Lakeshore carbide says 0.003" IPT for 1/4" carbide variable flute and lol 1600-2000 SFM
03:27 PM ItsFlipp_: Yeeeeah, can't go anywhere near that fast
03:27 PM ItsFlipp_: lol
03:27 PM JT-Shop: 10k on a 1/4" tool is a bit over 650 SFM
03:27 PM ItsFlipp_: I'm having heat buildup at 650
03:27 PM ItsFlipp_: yup
03:27 PM JT-Shop: I have one spindle that goes to 6k
03:28 PM JT-Shop: I also use flood coolant when milling 6061
03:28 PM JT-Shop: with mist you may have back way off with the SFM
03:29 PM gregcnc: oh boy, they don't even bother maintaining the coolant?
03:31 PM gregcnc: this particular stuff LB-2000 is known for being a gooey mess, it's some kind of vegetable oil iirc
03:31 PM Tom_L: ItsFlipp, i use this: http://tom-itx.no-ip.biz:81/~webpage/cnc/Rustlick1.jpg
03:33 PM Tom_L: mist works fine for me on 6061
03:33 PM XXCoder: Tom_L: very interesting disclaimer on container
03:35 PM ItsFlipp_: Cool. Yeah, it looks like that's Triethanolamine-based too
03:35 PM gregcnc: everyone has a different opinion on coolant, so many sources and types along with endless applications
03:35 PM Tom_L: yeah
03:36 PM ItsFlipp_: yup. I figure as long as I find something that works, I'll stick with it :)
03:36 PM Tom_L: https://itwprofessionalbrands.com/litart/tech_647.pdf
03:36 PM Tom_L: my friend used it in his shop for years
03:36 PM Tom_L: i figure it's good enough for me
03:36 PM ItsFlipp_: https://itwprofessionalbrands.com/litart/SDS_Rustlick_76005.pdf
03:36 PM ItsFlipp_: that's the full SDS
04:00 PM Deejay: gn8
04:22 PM jthornton: finally the cheap bastard turned on the heat in the house...
04:29 PM Jymmm: jthornton: Would this cheap bastartd go by the initials JT ?
04:30 PM gloops: been like a summer days here today, 16C +, ive been outside all afternoon in a T-shirt
04:30 PM jthornton: aye
04:31 PM jthornton: high here today was 7C
04:31 PM gloops: not sure if the february record went today, not normal weather
04:32 PM Jymmm: jthornton: Sadly, you probably have all the parts to make the heater I'm working on too
04:32 PM jthornton: I probably have at least 2 of each part
04:32 PM Jymmm: jthornton: Basically burn for 2-3 hours, heat for 24-36 hours
04:33 PM jthornton: what heater is that?
04:33 PM Jymmm: I have one of these propane torches, But I just want an open flame, any thoughts? https://images.homedepot-static.com/productImages/d8ccb336-0f86-4e67-a561-b144a0256bac/svn/bernzomatic-torches-tanks-ul2317-64_1000.jpg
04:33 PM Jymmm: like a bunsen burn sorta thing
04:34 PM jthornton: turn it down real low
04:34 PM gloops: close the air holes up
04:34 PM Jymmm: jthornton: It's kinda a hybrid rocket stove / mass heater sorta thing
04:35 PM Jymmm: jthornton: I tried that already,, still torch
04:35 PM Jymmm: gloops: I can try that
04:36 PM gloops: most people want a bluer hotter flame though? lol
04:36 PM Jymmm: jthornton: Too bad you didn't install udnerfloor tubing when you poured the slab for the new workshop
04:37 PM jthornton: why is that?
04:37 PM Jymmm: gloops: Yeah, it's too hot for this aplication, just want something like a "bigger" pilot light you might see on a stove
04:37 PM Jymmm: jthornton: wrap copper pipe aroudn the wood stove flue and you have hot water underfloor radiant heating
04:38 PM Jymmm: no pump required
04:38 PM jthornton: too much effort and cost for too little return
04:38 PM Jymmm: jthornton: 100 ft of tubing is like $40
04:39 PM Jymmm: tree companies just throw away the chips = free fuel
04:40 PM jthornton: it would take 750' of tubing in the slab with all the support hardware so it's just not worth the cost... for a bathroom floor maybe
04:40 PM Jymmm: It be nice to wark in the shop in the wmorning toasty warm though
04:41 PM gloops: we always used to say when we had coal fires here - it heats the whole house, the chimney stack would soak up the heat and release it at night when the fire was out
04:41 PM jthornton: lol my shops are all warm and toasty at 70F
04:44 PM Jymmm: jthornton: at 6am ???
04:44 PM Jymmm: gloops: DOOOOOOD that totally worked, TYVM =)
