[05:20:17] <jthornton> thought I heard chickens squawking at 3:30... woke me up fast... must have been dreaming lol
[05:20:51] <XXCoder> that or you dont have any left now ;)
[05:24:50] -!- EntropyWizard has quit [Quit: Leaving.]
[05:26:05] <jthornton> they are all there
[05:26:41] <XXCoder> yeah was likely they was fine lol
[05:27:05] <XXCoder> im sorta amazed to see there was small amount of flat area snow.
[05:27:14] <XXCoder> its under trees though so probably preserved
[05:28:29] <jthornton> our snow is long gone it's just wet out there
[05:28:47] <XXCoder> almost all jus piles here
[05:28:53] <XXCoder> slowly turning brown
[05:30:31] <jthornton> yea the coffee is ready
[05:33:19] <XXCoder> yay none for me thanks :)
[05:36:10] <jthornton> I need to figure out how to install windows xp and get by the phone home crap
[05:37:43] -!- usertogo has joined #linuxcnc
[06:00:40] <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
[06:01:07] <XXCoder> why cant install directly on pc?
[06:01:07] <jthornton> it's such a pain you have a legal copy of windblows xp but can't install it
[06:01:20] <jthornton> you have to activate it
[06:01:34] <jthornton> and now xp down here is broken
[06:01:41] <XXCoder> bleh
[06:02:03] <jthornton> yea and I use acad 10 on xp for electrical drawings
[06:02:10] <XXCoder> https://www.wikihow.com
[06:03:26] <jthornton> lol I have the genuine serial key
[06:03:57] <XXCoder> yeah but honestly xp is so old I doubt microsoft will knock your door, AND you have copy you can show them
[06:04:27] <XXCoder> if activation is issue that method just bypasses it outright.
[06:05:07] <XXCoder> it is also easy, basically delete registery key at right time then modify access right to that specific key root then done
[06:05:16] <jthornton> yea I'll try that, I tried a similar one before
[06:05:17] <XXCoder> using wrong words but whatever heh
[06:05:25] <jthornton> yep
[06:13:32] <Tom_L> morning
[06:14:00] <jthornton> morning
[06:14:52] <Tom_L> you should be able to swap xp out but will have to reinstall some drivers etc
[06:15:19] <Tom_L> i've done it a time or two but not the norm
[06:15:45] <jthornton> swap xp for what?
[06:16:08] <Tom_L> move from one pc to another
[06:16:33] <Tom_L> iirc i used ghost
[06:16:34] <jthornton> move from my laptop to the desktop? how?
[06:16:57] <Tom_L> oh, i'm not sure about that
[06:17:08] <jthornton> hmm I think I have a floppy with ghost on it
[06:17:09] <Tom_L> you could pull the hdd and get an adapter
[06:17:19] <Tom_L> i've done that then did a ghost copy on the pc
[06:17:52] <jthornton> I think I'll do a system image then try and install that
[06:18:19] <jthornton> or just install acad on the laptop and use it
[06:18:35] <jthornton> but what a pain to try and draw on a laptop
[06:18:48] <Tom_L> true
[06:18:59] <Tom_L> it's pain enough just to draw with acad
[06:19:38] <jthornton> I have an electrical add on that makes it easy to draw ladder diagrams of electrical circuits

[06:20:18] <CNC_Brian> Morning Chaps
[06:20:34] <jthornton> that's one I made before xp puked
[06:20:39] <jthornton> morning
[06:23:35] <CNC_Brian> Im surprised you haven't got classic ladder running Chicken operations
[06:24:07] <jthornton> lol, I have a Raspberry Pi 3 b running the show
[06:24:46] <jthornton> speaking of chickens I think one just went into the nest box
[06:25:52] <CNC_Brian> You need a webcam.
[06:26:33] <Tom_L> he has an offline webcam i believe
[06:26:36] <jthornton> I have a nest box cam but it's on the egg collection side
[06:26:41] <jthornton> yea several
[06:30:01] <Tom_L> started on my external thread macro last night
[06:30:04] <CNC_Brian> Don't share the URL with me, I will never get any work done
[06:30:15] <Tom_L> may end up combining them eventually
[06:30:55] <Loetmichel> CNC_Brian: i had a "work webcam" in my last job... was kinda funny...
[06:32:09] <jthornton> https://imagebin.ca
[06:32:16] <jthornton> that is before I put the lights in
[06:34:37] <CNC_Brian> Nice and clean in there.
[06:34:59] -!- asdfasd1 has joined #linuxcnc
[06:36:14] <jthornton> yea the false floor comes out for brushing off the tracked in dirt and crap
[06:37:49] <XXCoder> nice
[06:40:33] <CNC_Brian> Anyone seen a good design for a home-brew tool hight setter?
[06:42:00] <Loetmichel> CNC_Brian: timelapse of an exemplary day back then: http://www.cyrom.org
[06:42:41] <jthornton> I use a dowel to set the Z of my tools
[06:44:26] <CNC_Brian> Yes that's what I do at the moment got a 20mm gauge pin
[06:44:33] <jthornton> new gimp for windblows is a bit strange but no more windows scattered all over the place lol
[06:45:07] <CNC_Brian> Got the probe sorted so tool setter is next before I Get a BT30 spindle then a ATC
[06:45:10] <XXCoder> heard it changed to mdi type
[06:45:16] <XXCoder> guess its true
[06:45:25] <CNC_Brian> Should keep me busy for a couple of years
[06:45:32] <jthornton> mdi?
[06:45:52] <jthornton> this is a photo from my run camera https://imagebin.ca
[06:46:18] <XXCoder> not mdi in cnc terms, but programming. basically window with smaller windows inside it, or can move to sides etc and stick
[06:52:43] <jthornton> hmm it has tabs for each image now and doesn't have the focus problems it had in the past
[07:07:33] -!- emsjessec has joined #linuxcnc
[07:07:39] <CNC_Brian> Yes that more like I expected. If you could find a used for chicken poop you would be a rich man.
[07:07:59] <jthornton> I make compost with it
[07:08:40] <XXCoder> used lol
[07:08:59] <XXCoder> chickens crap is very rich soil enricher right?
[07:10:04] <jthornton> yea, I mix it with leaves in the winter and grass clippings in the summer
[07:10:30] <jthornton> I have a 3 station compost bin and the one with fresh poop stays covered up
[07:11:16] <XXCoder> would love composting to lessen garbage but too lazy
[07:11:26] <CNC_Brian> I have a little place in Spain and a neighbour covered his olive trees in chicken poop and kill them all.
[07:11:33] <XXCoder> plus neighbors would complain
[07:11:46] <XXCoder> ouch
[07:12:18] <jthornton> yea you can't use raw poop it's too hot lol
[07:12:45] <jthornton> a covered compost bin so they don't have anything to complain about lol
[07:12:51] <XXCoder> I need to get uncomposted horse crap. need to kill horsetails :( very hardy weed

[08:09:05] <XXCoder> no wonder weathers been strange
[08:10:36] <jthornton> weird
[08:13:18] <XXCoder> yeah
[08:13:49] <XXCoder> sat have been upgraded to snow at evening and night
[08:13:57] <XXCoder> then clear but very cold later
[08:14:43] <XXCoder> funny because normally winter is just boring freezing for while, and not stay type of snow.
[08:15:14] <XXCoder> humans probably invented language to talk about weather. oh and danger commucation LOL

[11:50:45] <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
[11:53:22] <SpeedEvil> Is the big red button e-stop only?
[11:59:08] <The_Ball> SpeedEvil, yes, mushroom type
[11:59:50] <The_Ball> 3d -> https://imgur.com
[11:59:52] <SpeedEvil> I would put it clear of the other controls on the bottom-right
[12:01:09] <The_Ball> I was taking the layout from haas' control panel where it's in the middle, what is your thinking for bottom-right?
[12:01:41] <SpeedEvil> To have it in a visually uncluttered space.
[12:01:50] <SpeedEvil> I guess it's not important really.
[12:02:20] <The_Ball> I haven't got much space to work with on this machine

[12:03:48] <gregcnc> coolant?
[12:05:08] <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
[12:05:25] <fragalot> nobody remembers the last one
[12:05:44] <The_Ball> But I'm thinking of perhaps a rotary switch for coolant override-on / off / auto
[12:24:14] <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
[12:24:54] <CNC_Brian> Could it be the hardware Stephen is just much faster and the stepper drives are missing steps?
[12:25:18] <CNC_Brian> stepgen
[12:26:53] <CNC_Brian> Everyone has gone to the pub:-(
[12:27:16] <gloops> no joint following error or anything?
[12:28:32] <CNC_Brian> Nope, but I have got the ferror set to .1 mm
[12:28:46] <CNC_Brian> min_ferror is .25
[12:29:11] <CNC_Brian> Not sure where I got these values from though soo long ago
[12:30:00] <CNC_Brian> My Stephen max accel somehow went up from 970 to 1500???
[12:30:30] <CNC_Brian> But it glitches mid way through a move, not at the beginning. Very strange
[12:30:44] -!- Abrafax has joined #linuxcnc
[12:31:32] <gloops> im a bit rusty with the basic config
[12:31:54] <CNC_Brian> Im also running a nice new qtpyvcp maybe my old PC is now too slow
[12:32:44] <CNC_Brian> Yes no problem, just though I would ask as Im sure its been seen before.
[12:32:49] <CNC_Brian> Cheers.
[12:35:45] <gloops> i had some issues with stepgen values when i set mine up, i cant remember what now
[12:36:29] <gloops> your ferror values are the default i think
[12:39:26] <gloops> stepgen.N.maxvel float rw
[12:39:26] <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−pulses thread period, it will be reset to the highest attainable value.

[13:14:59] <pcw_home> CNC_Brian: I would double the step times and see if the problem goes away
[13:16:25] <pcw_home> I see this _very_ often when people use a hardware step generator after having used a parallel port (step times too short)
[13:17:13] <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...

[13:41:45] -!- syyl has joined #linuxcnc
[13:44:04] <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
[13:45:10] <rmu> without feedback, you can disconnect the motors, and linuxcnc will behave exactly the same
[13:48:08] <ItsFlipp_> jthornton, Tom_L: Quick update from some tests last night to try and reduce the heat in the part
[13:48:27] <ItsFlipp_> upped chipload from 0.0027->0.0034, same SFM
[13:48:36] <ItsFlipp_> surface finish during roughing was *gorgeous*
[13:48:55] <ItsFlipp_> uuuuunfortunately didn't help the part. Superglue fixture failed in the same way
[13:49:11] <ItsFlipp_> upped again to 0.0043
[13:49:25] <ItsFlipp_> Surface finish still very, very good, but not quite as spectacular as 0.0034
[13:49:29] <ItsFlipp_> ... same failure
[13:49:39] <ItsFlipp_> Then I looked up the coolant I've been using
[13:49:54] <ItsFlipp_> Some generic stuff from Tormach, DuraKut 9000B
[13:50:01] <ItsFlipp_> Apaprently the flash point of it is 100C
[13:51:02] <ItsFlipp_> other coolants are apparently much higher (e.g. KoolMist is 180C according to MSDS)
[13:51:14] <ItsFlipp_> I'm beginning to wonder if the coolant is just ... bad
[13:51:28] <ItsFlipp_> We'll see tonight. Got some better stuff on the way
[14:33:22] -!- tumdedum has quit [Remote host closed the connection]
[14:34:38] <gregcnc> flood coolant?
[14:34:53] <gregcnc> flash point is irrelevant
[14:35:25] <gregcnc> itsflipp_^
[14:36:19] <gregcnc> if the part gets hot enough the glue will fail
[14:36:55] -!- JesusAlos has quit [Quit: JesusAlos]
[14:37:11] <methods_> yeah just use through spindle coolant
[14:40:02] * 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
[14:40:02] * 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)... :-(
[14:44:05] <Jymmm> powder? Nah, just toss on some hello kitty stickers and call it a day
[14:47:54] <fragalot> say it's clear coated
[14:50:21] <methods_> natural finish
[14:53:01] <gloops> get the heat resistant superglue - 150C

[15:27:08] <Jymmm> Loetmichel: https://www.amazon.com
[15:27:25] <ItsFlipp_> gregcnc: mist coolant
[15:27:48] <Jymmm> Loetmichel: better yet... https://www.amazon.com
[15:27:58] <ItsFlipp_> gregcnc: sure, that's how my SG fixturing has failed so far
[15:28:20] <ItsFlipp_> I'm just trying to nail down exactly why the part is absorbing so much heat instead of the chips
[15:31:24] <gregcnc> how did you determine the chips aren't absorbing heat?
[15:32:45] <gregcnc> mist with neat oil or water based?
[15:33:24] <ItsFlipp_> Mist w/water based, I believe https://www.tormach.com
[15:33:53] <gregcnc> did you add water?
[15:34:09] <ItsFlipp_> I've done some similar ops before on a machine at work, and the part didn't get smoking hot :(
[15:34:18] <ItsFlipp_> no, it's premixed. "Use Neat"
[15:35:10] <ItsFlipp_> (I've got some KoolMist 77 on the way to test that)
[15:35:31] <gregcnc> no water in that, so minimal cooling

[15:37:00] <ItsFlipp_> MSDS suggests it's basically entirely Polybutene Copolymer
[15:37:04] <gregcnc> right
[15:37:43] <gregcnc> at work also mist coolant?
[15:38:00] <ItsFlipp_> Interesting. I was under the assumption that the majority of the cooling came from the fluid itself, whatever the composition
[15:38:21] <gregcnc> "coolant" is many things
[15:39:17] <ItsFlipp_> Work I've cut both flood and dry (no mister available there yet)
[15:39:29] <gregcnc> different types work in different ways
[15:39:44] <ItsFlipp_> Dry was less than ideal, but the part didn't actually get that hot
[15:39:53] <gregcnc> if you want to keep parts cool, flood is the way to go
[15:40:02] <gregcnc> same cutter?
[15:40:18] <ItsFlipp_> initially tried same HSS cutter, then tried a carbide
[15:40:43] <ItsFlipp_> I initially thought my S&F were a bit aggressive, but aside from the heat the surface finish and chip stream looked great
[15:41:22] <ItsFlipp_> 10kRPM@67 IPM, w/ 2 flute Carbide ZrN coating (translates to ~.0034 IPT and ~550-ish SFM)
[15:42:38] <ItsFlipp_> .45 DOC, .03125 WOC (~12% of diameter)
[15:43:20] <ItsFlipp_> that was the best surface finish, but I've also tried 10k@20, 10k@80, and 8.4k@31
[15:43:27] <ItsFlipp_> all ended up heating the part pretty good
[15:44:22] <gregcnc> what else is different when it works?
[15:45:33] <Loetmichel> Jymmm: i doubt the (military) customer would think thats funny.
[15:45:54] <ItsFlipp_> aside from different machine (slightly older model), that's what I'm tryin' to pin down :/
[15:46:02] <ItsFlipp_> my toolpaths are likely a bit different
[15:46:16] <gregcnc> part is the same?
[15:46:59] <ItsFlipp_> same part, same fixture style (sac plate->painters tape->Cyanoacrylate->painters tape->stock)
[15:47:32] <ItsFlipp_> does that 10k@67IPM cut sound wonky at all?
[15:47:39] <ItsFlipp_> still (relatively) new at dialing in S&F
[15:50:28] -!- fragalot has quit [Quit: Lost terminal]
[15:55:41] <gregcnc> aluminum?
[15:55:49] <ItsFlipp_> ya. 6061
[15:56:39] <gregcnc> essentially you can't go too fast in SFM, unless it's melting, or feed too hard unless you're breaking tools
[15:58:39] <Jymmm> Loetmichel: Hey, you never know
[16:00:05] <Jymmm> Loetmichel: Here we go... https://i.pinimg.com
[16:01:25] <gregcnc> i guess it's the tape adhesive that's failing not the superglue
[16:01:42] <ItsFlipp_> So far yes, that's pretty much what I've observed
[16:02:08] <ItsFlipp_> but is it normal for 6061 parts to get so hot the coolant basically boils off into a fog?
[16:02:23] <gregcnc> sure
[16:03:05] <gregcnc> either you had better tape at work or just got lucky a few times
[16:03:56] <ItsFlipp_> ha, true enough I guess
[16:04:59] <ItsFlipp_> so it's somewhat normal to have parts heat up to >100C during machining?
[16:07:23] <gregcnc> 100% of the spindle power ends up in the part and chips
[16:07:52] <gregcnc> it's hard to guess how much in each
[16:08:14] <ItsFlipp_> true
[16:08:19] <gregcnc> I guess some heat ends up in the cutter
[16:08:45] <ItsFlipp_> I guess myabe I'm just getting overconcerned that the part was getting hot enough during adaptive clearing ops to instantly vaporize coolant
[16:08:52] <ItsFlipp_> which in turn created a huge fog inside the machine
[16:12:18] <gregcnc> a different oil may smoke less. water soluble oil in the mister would aid in cooling
[16:12:41] <ItsFlipp_> sounds good, thanks. I'll try that
[16:13:18] <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
[16:14:02] <ItsFlipp_> have some KoolMist 77 on the way; ya cut it something like 1:20 with water
[16:22:48] <ItsFlipp_> Yeah, we had the same problem at work with the flood coolant
[16:23:08] <ItsFlipp_> the coolant is in an open-ish tank, and the water would end up evaporating over time
[16:23:32] <ItsFlipp_> and after a while the coolant got more and more concentrated, which began leaving a stickier and stickier mess inside the machine
[16:24:36] <JT-Shop> Lakeshore carbide says 0.003" IPT for 1/4" carbide variable flute and lol 1600-2000 SFM
[16:24:52] <ItsFlipp_> Yeeeeah, can't go anywhere near that fast
[16:24:54] <ItsFlipp_> lol
[16:25:06] <JT-Shop> 10k on a 1/4" tool is a bit over 650 SFM
[16:25:12] <ItsFlipp_> I'm having heat buildup at 650
[16:25:14] <ItsFlipp_> yup
[16:25:26] <JT-Shop> I have one spindle that goes to 6k
[16:25:56] <JT-Shop> I also use flood coolant when milling 6061
[16:26:09] <JT-Shop> with mist you may have back way off with the SFM
[16:26:44] <gregcnc> oh boy, they don't even bother maintaining the coolant?
[16:28:59] <gregcnc> this particular stuff LB-2000 is known for being a gooey mess, it's some kind of vegetable oil iirc
[16:29:16] <Tom_L> ItsFlipp, i use this: http://tom-itx.no-ip.biz:81
[16:31:19] <Tom_L> mist works fine for me on 6061
[16:31:31] <XXCoder> Tom_L: very interesting disclaimer on container
[16:33:02] <ItsFlipp_> Cool. Yeah, it looks like that's Triethanolamine-based too
[16:33:06] <gregcnc> everyone has a different opinion on coolant, so many sources and types along with endless applications
[16:33:30] <Tom_L> yeah
[16:33:49] <ItsFlipp_> yup. I figure as long as I find something that works, I'll stick with it :)
[16:34:00] <Tom_L> https://itwprofessionalbrands.com
[16:34:13] <Tom_L> my friend used it in his shop for years
[16:34:21] <Tom_L> i figure it's good enough for me

[17:20:11] <jthornton> finally the cheap bastard turned on the heat in the house...
[17:27:20] <Jymmm> jthornton: Would this cheap bastartd go by the initials JT ?
[17:28:12] <gloops> been like a summer days here today, 16C +, ive been outside all afternoon in a T-shirt
[17:28:29] <jthornton> aye
[17:28:56] <jthornton> high here today was 7C
[17:29:27] <gloops> not sure if the february record went today, not normal weather
[17:29:36] <Jymmm> jthornton: Sadly, you probably have all the parts to make the heater I'm working on too
[17:30:04] <jthornton> I probably have at least 2 of each part
[17:30:22] <Jymmm> jthornton: Basically burn for 2-3 hours, heat for 24-36 hours
[17:30:35] <jthornton> what heater is that?
[17:31:07] <Jymmm> I have one of these propane torches, But I just want an open flame, any thoughts? https://images.homedepot-static.com
[17:31:29] <Jymmm> like a bunsen burn sorta thing
[17:32:01] <jthornton> turn it down real low
[17:32:13] <gloops> close the air holes up
[17:32:13] <Jymmm> jthornton: It's kinda a hybrid rocket stove / mass heater sorta thing
[17:32:24] -!- EntropyWizard has joined #linuxcnc
[17:32:35] <Jymmm> jthornton: I tried that already,, still torch
[17:32:45] <Jymmm> gloops: I can try that
[17:33:53] <gloops> most people want a bluer hotter flame though? lol
[17:34:09] <Jymmm> jthornton: Too bad you didn't install udnerfloor tubing when you poured the slab for the new workshop
[17:34:42] <jthornton> why is that?
[17:34:47] <Jymmm> gloops: Yeah, it's too hot for this aplication, just want something like a "bigger" pilot light you might see on a stove
[17:35:32] <Jymmm> jthornton: wrap copper pipe aroudn the wood stove flue and you have hot water underfloor radiant heating
[17:35:58] <Jymmm> no pump required
[17:36:10] <jthornton> too much effort and cost for too little return
[17:36:26] <Jymmm> jthornton: 100 ft of tubing is like $40
[17:36:30] -!- justanotheruser has quit [Ping timeout: 264 seconds]
[17:37:19] <Jymmm> tree companies just throw away the chips = free fuel
[17:37:43] <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
[17:38:19] <Jymmm> It be nice to wark in the shop in the wmorning toasty warm though
[17:38:42] <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
[17:38:45] <jthornton> lol my shops are all warm and toasty at 70F
[17:41:56] <Jymmm> jthornton: at 6am ???
[17:42:08] <Jymmm> gloops: DOOOOOOD that totally worked, TYVM =)
[17:42:26] <Jymmm> gloops: that was the simplest solution ever =)
[17:44:02] <Jymmm> jthornton: So wait, the cheap bastard freeze the better half out, but the shops are 70F ??? lmao
[17:44:17] <Jymmm> priorities =)
[17:45:11] <gloops> well i never did much chemistry Jymmm but i did play with the bunsen burners a lot
