12:03 AM Wolf__: because you dont have room for one?
12:08 AM pink_vampire: Wolf__: you know me better then my mom O_O
12:08 AM Wolf__: =D
12:10 AM ItsFlipp: any tips on drilling 6061? I can't seem to find the right combo for a 2.5mm 118* drill bit. Broke another yesterday :C
12:11 AM ItsFlipp: using fobuster + koolmist, 3800 RPM + 98 ft/min + ..955 IPM + peck depth of 0.1"
12:11 AM ItsFlipp: + center/spot drilling
12:12 AM pink_vampire: I love to drill with high speed and feed
12:12 AM ItsFlipp: err, sorry, 9.55 IPM
12:12 AM pink_vampire: but taking very small bite each time
12:12 AM MarcelineVQ: ItsFlipp: are you getting galling on the bits?
12:13 AM Wolf__: ^ gummy drilling
12:13 AM pink_vampire: and I'm using alcohol or baby oil as cutting oil
12:13 AM ItsFlipp: it seems that way. I've used a couple of different coatings, and it seems like there's a super fine layer of aluminum deposited on the surface after using it a few times
12:14 AM MarcelineVQ: you want to be in an out fast on aluminum, though not so fast you catch on thin stuff, peck drilling like pink_vampire is suggesting is a good idea to observe whether you're getting stuff stuck on your bit
12:14 AM ItsFlipp: not like complete welding
12:14 AM ItsFlipp: yup, I'm using peck depth of 0.1"
12:14 AM MarcelineVQ: I've heard you should avoid coated bits on alu, idk though
12:14 AM ItsFlipp: with fulil retract
12:14 AM pink_vampire: if your cutter become silvery color - that is bad
12:15 AM ItsFlipp: hard to find bright m3 pilot drills in the States here :(
12:15 AM ItsFlipp: pink_vampire: aye, agreed
12:15 AM pink_vampire: you need to keep the cutter wet
12:15 AM jym: hey pink_vampire ltns
12:15 AM MarcelineVQ: What's in your buster?
12:15 AM ItsFlipp: koolmist
12:15 AM pink_vampire: jym: yeah I know
12:15 AM jym: Tom_L: good luck wwith all that, I feel for ya
12:16 AM MarcelineVQ: Any particular koolmist or is there just one?
12:16 AM pink_vampire: ItsFlipp: for deep hole you want it drippy wet
12:16 AM pink_vampire: not just mist
12:17 AM ItsFlipp: I've cranked up the coolant to where calling it "minimum quantity lubricant" is basically a misnomer
12:17 AM pink_vampire: and also keep the aluminum cold
12:17 AM ItsFlipp: I wish I had flood, but sadly I don't :C
12:17 AM MarcelineVQ: wonder if you can call them and ask why you're galling on their juice
12:17 AM Wolf__: use a squirt bottle
12:18 AM ItsFlipp: it works wonders for milling; drilling has just been the bane of my setups for months :C
12:18 AM MarcelineVQ: there's no dwell in the hole yeah?
12:18 AM pink_vampire: it is not just about cooling it is also about making a film of coolant on the cutter, to prevent the metal to stick to it
12:18 AM ItsFlipp: and blowing/breaking any chips that come out, ya?
12:20 AM MarcelineVQ: pecking + fogbuster should have the tool coated reasonably :<
12:20 AM ItsFlipp: MarcelineVQ: I would have thought so too :C
12:20 AM pink_vampire: ItsFlipp: use sharp carbide drill, 20-40K rpm, and go in-out-in-out and bite like 0.1 mm each time, the chips will be like dust
12:21 AM ItsFlipp: I'm using pretty close to what FSWizard suggests: 3800 RPM and 7.3 IPM
12:21 AM ItsFlipp: pink_vampire: wow, that's like an order of magnitude more than FSW suggests...?!
12:21 AM ItsFlipp: O.o
12:21 AM pink_vampire: this is how I'm dealing with it
12:21 AM ItsFlipp: the silvery coating suggests I might be burnishing too, ya?
12:22 AM ItsFlipp: 10k is my RPM limit, so I can try that
12:22 AM ItsFlipp: what's your feedrate?
12:22 AM pink_vampire: so go 10K
12:22 AM pink_vampire: max
12:22 AM pink_vampire: 2400mm/min
12:23 AM ItsFlipp: wow. I don't even rapid at 94 IPM O.o
12:25 AM pink_vampire: I know the way I'm trilling is not very efficient, but if i want to get the job done without risk the drill, this is what I do
12:25 AM ItsFlipp: okay, I'll give that a try
12:25 AM ItsFlipp: I mean at this point I've gotta try _something_ different
12:25 AM ItsFlipp: it's clearly not working
12:25 AM pink_vampire: with 2.5mm drill you want very very small chip load
12:25 AM ItsFlipp: do you do a full retract on peck?
12:26 AM pink_vampire: yeah, and lube it on the way
12:26 AM ItsFlipp: my current chip load is 0.0025 IPR (.0635 mm/rev)
12:26 AM pink_vampire: try to jog it first
12:26 AM pink_vampire: let me see in hsm
12:26 AM ItsFlipp: my machine only has 1.5HP @ 10k RPM, and realistically it's more like 1
12:27 AM pink_vampire: I'm turn on my computer
12:27 AM pink_vampire: hope you have a sec
12:27 AM ItsFlipp: np, only if you've got time :)
12:27 AM pink_vampire: 1.5HP on 2,5 mm drill
12:27 AM ItsFlipp: sure, I'm in no hurry. just CAMin' while the Mrs is still up
12:27 AM pink_vampire: that crazy
12:27 AM ItsFlipp: that's my max limit
12:27 AM ItsFlipp: not what I acually use :)
12:27 AM ItsFlipp: *actually
12:27 AM ItsFlipp: again, tiny machine :)
12:28 AM pink_vampire: what machine is that?
12:28 AM ItsFlipp: Tormach 770m... and even that took some convincing of Mrs Flipp
12:29 AM pink_vampire: why?
12:29 AM MarcelineVQ: ItsFlipp: calc I'm looking at is reccomending 12k rpm and 15-30 IPM feed
12:30 AM ItsFlipp: a) it's a hobby-ish; still have a day job b) we live in a tiny 1300 sf house c) our garage is 82" tall and the machine is ~80" tall O.o
12:30 AM pink_vampire: it is like 4 times the space I have
12:30 AM ItsFlipp: what do you run?
12:31 AM ItsFlipp: MarcelineVQ: Interesting, thanks. lemme calculate chip load from that and compare
12:31 AM ItsFlipp: MarcelineVQ: that's for a 2.5mm drill?
12:31 AM pink_vampire: G0704 with tons of upgrades
12:31 AM MarcelineVQ: yeah http://www.norsemandrill.com/feeds-speeds-drill.php
12:31 AM pink_vampire: servo spindle, and 60K aux spindle
12:32 AM ItsFlipp: Ha! That was my previous mill. It was a toss up between converting that to CNC and getting a Tormach... I couldn't afford the time moreso than the cost of the machine
12:33 AM ItsFlipp: Aluminum is weird. I still can't wrap my head around why going slower in terms of surface speed would be bad (assuming same chip load)
12:33 AM MarcelineVQ: heat, aluminum is softer and when heated becomes gummy/sticky
12:33 AM MarcelineVQ: so the faster you're cutting and leaving the more heat leaves with the chips
12:33 AM ItsFlipp: ... huh
12:34 AM MarcelineVQ: rubbing makes more heat than cutting, in short, and you rub when you get sticky
12:34 AM ItsFlipp: sure
12:34 AM ItsFlipp: but wouldn't the feed per tooth take care of that, clearing chips up the flute?
12:36 AM ItsFlipp: so IIUC, I was spinning at ~98 feet/min. if I up the RPM so that it's ~200 feet/min, that actually _lowers_ heat? O.o
12:36 AM MarcelineVQ: ideally but heat transfer has a speed limit in the real world so there's an advantage to getting ahead of heat buildup
12:38 AM ItsFlipp: I guess that's where my disconnect comes from. I feel like more surface speed = more friction. according to the sheet you listed I was going 2x too low in surface speed
12:39 AM ItsFlipp: IPM was at 19.5, but RPMs was ~3800
12:39 AM pink_vampire: according to HSM, 0.04mm per rev and 10K rpm, with 450mm plunge feed rate
12:39 AM pink_vampire: I think it will brake it
12:40 AM pink_vampire: start with 10K rpm and 200mm feed and take small bite and see how it feel / sound
12:41 AM pink_vampire: if you get rubbing, crank the feed rate
12:41 AM MarcelineVQ: it's a similar friction for a sharp cutter the difference is contact time and chip size. if I take away the same material but do it slower I've increased the time I'm actually touching the base material, this means I'm able to impart more heat to it. If I can take a larger chip by moving faster I can allow more heat to leave the base metal due to the chip being more massive and thus holding more heat
12:42 AM ItsFlipp: pink_vampire: thanks, I'll try that; my controller has the ability to tune feed rates during cutting
12:43 AM ItsFlipp: MarcelineVQ: Aye, I've observed a similar thing when turning my end mill S&F. I've dialed in my fav 1/4" end mill to the point where the chips are quite hot if I put my hand in to blow excess chips away, but the part itself is nice and cool
12:44 AM pink_vampire: https://i.imgur.com/097dpV6.mp4
12:44 AM MarcelineVQ: That's ideal,since a hot part is out of tolarance, it's expanded, so if you cut it it can turn out undersize when cooled
12:46 AM ItsFlipp: aye. don't have a sense of how much heat is going into the tool itself, but so far unless I've done something stupid like trying to accidentally go ramp>slot at 15>70 IPM I haven't broken an end mill yet
12:47 AM pink_vampire: the 770 is your first mill?
12:47 AM ItsFlipp: first CNC. second aftar my g0704 (well, g0752)
12:48 AM ItsFlipp: err, I mean... whatever the g0704 is with the DRO
12:48 AM pink_vampire: why did you switch to the 770?
12:48 AM ItsFlipp: I wanted CNC, and didn't have the time to convert it to CNC :/
12:49 AM ItsFlipp: it'd take me >= 1 year to convert it given my limited free time, and there's a good chance Mrs. Flipp and I will be expecting in the next year so that definitely puts a damper on time-spent-on-hobbies
12:49 AM ItsFlipp: :)
12:50 AM pink_vampire: the 770 is a nice machine, but not very good for the money, you can get nice used vmc for what they ask
12:50 AM ItsFlipp: sure, but I don't have 3-phase in my garage, and basically nothing else would fit in my tiny house :/
12:51 AM pink_vampire: some can take single phase
12:52 AM ItsFlipp: https://photos.app.goo.gl/qy3eabhTc74h3RPbA
12:53 AM ItsFlipp: I have literally -20mm clearance when it's at Zmax
12:53 AM pink_vampire: OK you got the 770M WOW
12:53 AM pink_vampire: WHY
12:53 AM ItsFlipp: work discount
12:53 AM ItsFlipp: it's not the servo one
12:54 AM ItsFlipp: and it's literally the only thing that'd fit in my garage :)
12:54 AM pink_vampire: it is a very basic machine for the price
12:55 AM ItsFlipp: agreed. Trust me, if I could buy some old iron and fit it in there I'd have done that in a heartbeat
12:55 AM pink_vampire: hope you got the iso30 and not the R8
12:56 AM ItsFlipp: the 770M has much better QA than the 770 v3
12:56 AM ItsFlipp: https://photos.app.goo.gl/c8AL2DspUsL8LKj98
12:57 AM pink_vampire: don't get me wrong the tormach is very nice machine for hobby stuff, but for $10K I think the hass mini mill will be better option
12:57 AM ItsFlipp: too tall :C
12:57 AM pink_vampire: datron neo
12:57 AM pink_vampire: any datron
12:59 AM pink_vampire: hass cm1
01:01 AM ItsFlipp: yeah, all good machines. I ended up getting mine for ~$9k after work discount, so wasn't _too_ bad
01:02 AM pink_vampire: done on the G0704 in one operation https://imgur.com/a/DPZUs3D
01:02 AM ItsFlipp: what's the material?
01:02 AM pink_vampire: 9K is a good price
01:02 AM pink_vampire: just a test on wood
01:03 AM ItsFlipp: any issues running wood+metal in same machine?
01:04 AM ItsFlipp: I've heard horror stories about running both wood/metal
01:04 AM pink_vampire: no issue
01:04 AM pink_vampire: but i never oil my machine
01:04 AM ItsFlipp: no worries about ignition from hot chips?
01:04 AM ItsFlipp: from sawdust?
01:05 AM pink_vampire: I'm using dry lubrication for the ways
01:05 AM pink_vampire: no
01:05 AM pink_vampire: it is just 60K rpm
01:05 AM ItsFlipp: still, that produces quite the sawdust storm, ya?
01:06 AM pink_vampire: no, it is just make a nice pile
01:07 AM pink_vampire: https://imgur.com/a/DPZUs3D
01:09 AM pink_vampire: ItsFlipp: ^
01:22 AM ItsFlipp: Ah, interesting. Have you noticed a big difference in material?
01:22 AM ItsFlipp: e.g. balsa/birch vs hardwood?
01:22 AM pink_vampire: I'm not sure what wood is that
01:22 AM pink_vampire: let me if there is a sticker on it
01:24 AM pink_vampire: ItsFlipp: the original spindle in the G0704 is now controlled as a C axis servo, so you can talk to it in degrees, the 60K spindle, is mount on the X axis, so the X become the Z and the Z is now the X, and the C is the A
01:24 AM ItsFlipp: wow. you got any full pics of your franken-g0704? :)
01:25 AM pink_vampire: https://i.imgur.com/w0Bk7ms.png
01:26 AM pink_vampire: better picture https://i.imgur.com/VjW3gkp.png?1
01:27 AM pink_vampire: the control panel https://i.imgur.com/JAotJPH.png
01:28 AM ItsFlipp: wow, that's spectacular
01:28 AM ItsFlipp: you still running the same lead screws? or replace with ballscrews?
01:28 AM pink_vampire: ball screws and servos
01:29 AM pink_vampire: I want to upgrade the rails
01:30 AM pink_vampire: https://i.imgur.com/R2x7xBf.png the broken cast part, and my machinable design https://i.imgur.com/dRiAkFT.png
01:31 AM pink_vampire: https://i.imgur.com/ks1ock5.png servo controller, and the reverse energy dump
01:32 AM pink_vampire: https://i.imgur.com/gJjuGUi.png fittings that I made
01:35 AM pink_vampire: if you like lathe job you might like this albums https://imgur.com/a/kmzBWs8 https://imgur.com/a/nB07GFw
01:41 AM pink_vampire: ItsFlipp: ^
01:57 AM Deejay: moin
01:58 AM pink_vampire: hi Deejay
01:58 AM Deejay: hi pink
02:52 AM Valen: ahoyhoy
03:25 AM ItsFlipp: pink_vampire: thx, looks awesome. wish I had the time to do some/all of those mods :)
03:26 AM ItsFlipp: those plugs are really a testament to how accurate your tooling is
04:25 AM pink_vampire: ItsFlipp: what plugs?
05:18 AM Tom_L: morning
06:00 AM BitEvil is now known as SpeedEvil
08:03 AM gregcnc: pink_vampire that part looks good, you have 4th axis in HSM?
08:03 AM XXCoder: aww i wasnt in when pink_vampire linked to a pic or somethinbg?
08:08 AM Deejay: not in the last 6 hours
08:08 AM gregcnc: it was 7 or 8
08:09 AM gregcnc: https://imgur.com/a/DPZUs3D
08:11 AM XXCoder: that looks interesting
08:11 AM XXCoder: I see shes using the 4th axis spindle
09:59 AM esch: yeesh, it'd be nice if AB wouldn't change tag names for seemingly no reason
11:27 AM Tom_itx is now known as Tom_L
12:09 PM flyback is now known as fishhead
12:09 PM fishhead is now known as i8086
12:11 PM i8086 is now known as flyback
12:15 PM * jthornton managed to get home without getting wet
12:39 PM * Tom_L wishes he could say the same
04:10 PM cerna: pink_vampire: What does "Check for Errors" button/light do?
04:14 PM andypugh: Where?
04:16 PM cerna: > the control panel https://i.imgur.com/JAotJPH.png
04:16 PM cerna: There, in the image, right top.
04:21 PM andypugh: Looks like an indicator light. Perhaps it is connected to the driver output error pins?
04:21 PM andypugh: But pinky seems to be ignoring your question.
04:23 PM cerna: Seems like it. And seems like I should go back to kindergarden and relearn sides.
04:23 PM cerna: Was interested if it isn't some HAL magic.
04:24 PM andypugh: It’s the cabinet’s right-hand side, you can tell by the googly eyes.
04:29 PM CaptHindsight: andypugh: do you have a howto for building the kernel and LCNC packages?
04:30 PM CaptHindsight: or is there one that you followed?
04:31 PM andypugh: Not really. I probably should write one for my own reference, as I have very nearly forgotten what I did.
04:31 PM andypugh: It really wasn’t terribly difficult, though. Basically you need to follow the NTULINIX readme.INSTALL
04:32 PM andypugh: I will try to put it on a Wiki page after dinnner
04:50 PM Deejay: gn8
05:17 PM * jthornton is one tired puppy tonight
06:17 PM pink_vampire: cerna: it is show if there is obvious error like over current / servo / controller heat up, and stuff like that
06:28 PM andypugh: CaptHindsight: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Building_RTAI_5.2_Packages
06:32 PM pcw_mesa: Is LinuxCNC running on the newly baked RTAI kernel?
06:32 PM andypugh: Yes.
06:32 PM pcw_mesa: 32 or 64 bit?
06:32 PM andypugh: 64 bit.
06:33 PM pcw_mesa: Wow that's great!
06:33 PM andypugh: (I don’t see any point building for 32 bit x86)
06:33 PM andypugh: I admit I haven’t _actually_ run hardware with it yet.
06:33 PM andypugh: As in my machine tools.
06:34 PM pcw_mesa: I means you could have a common dist with RTAI/Preempt-RT kernels
06:34 PM andypugh: I guess that I should, and the debs make it fairly easy.
06:34 PM andypugh: Yes, I am not sure how to manage that.
06:34 PM pcw_mesa: common _64bit_ dist I mean
06:35 PM andypugh: Certainly the ISO could contain both kernels, and having RTAI installed on a Preempt machine is not a problem if you don’t run it.
06:35 PM andypugh: But LinuxCNC is different depending on the kernel it is built against.
06:36 PM pcw_mesa: Right
06:36 PM pcw_mesa: maybe 2 ISOs that are identical except kernel/lLinuxCNC
06:37 PM andypugh: I think the answer might be to have a preempt ISO for wider compatibility, with instructions on how to make Synaptic point at the RTAI version, and a linuxcnc-rtai package that depends in the RTAI and kernel packages.
06:38 PM andypugh: (And vice-versa. So yes, two ISOs)
06:38 PM pcw_mesa: so its just a apt-get away
06:38 PM andypugh: I guess that is mozmck ’s decision :-)
06:38 PM pcw_mesa: Possibly Buster?
06:38 PM andypugh: Definitely bister.
06:39 PM andypugh: (Buster)
06:39 PM andypugh: I have LinuxCNC running on Buster on a PI4
06:40 PM pcw_mesa: I should try Buster, not sure if the Ethernet stuff will be an issue = missing iptables
06:44 PM andypugh: I think I need to set up a local APT archive to test with.
06:44 PM pcw_mesa: I managed to do some minor hostmot2 driver patching (added offset-mode pin to PWMgen) Whats the best way to merge this kind of change? (i did it in a separate local branch)
06:44 PM andypugh: But, ’tis time to sleep.
06:48 PM jthornton: pcw_mesa: do you have push rights?
06:56 PM _unreal_: FUCK YOU windwos
06:56 PM _unreal_: god....! I hate windows
06:57 PM _unreal_: I shut down ALLLLLLLLLLL updating everything. and it stilllll rebooted
06:57 PM Centurion_Dan: how do you get light in your house without windows??
06:57 PM _unreal_: so I was sitting at my linux key in prompt
06:57 PM DaViruz: maybe he got those newfangled electric lights
06:57 PM _unreal_: clearly this man has never been introduced to fire
06:58 PM _unreal_: GOD I hate windows
06:58 PM Centurion_Dan: _unreal_: oh sure, but I reserve those things for at night when there is not enough natural light...
06:59 PM _unreal_: just finished installing mach3 for testing a motion controller I just got. and I forgot. its been so long I forgot that it forces you to reboot with out na option to reboot later. so my cnc controlling computer just rebooted on me when I was setting up for a cut I was planning on
06:59 PM _unreal_: now I have to DO THAT all over again too
06:59 PM _unreal_: GOD I HATE windows
07:00 PM Centurion_Dan: so what does windows have to do with linuxcnc
07:01 PM jthornton: geez I have to update the metrics agent for the forum and I don't even know wtf that is
07:04 PM _unreal_: great now my netbook. the one I used for controlling my CNC is not booting
07:04 PM _unreal_: wtf
07:04 PM _unreal_: Centurion_Dan, easy its inferior
07:05 PM _unreal_: OH THANK GOD! 3rd time I've rebooted it. I have picture this time
07:06 PM _unreal_: now I'm going to have to wait prob what 30 min for the damn thing to finish booting even
07:09 PM _unreal_: OMG..... all I want to do is mill the grape vine onto the wine bottle holder and I'm done.
07:09 PM Centurion_Dan: _unreal_: Microsoft loves making you wait... that's why I've banned it from my house and office... Unfortunately my clients still use that shitty OS, but I'm ok with that because they have to pay me for all the time of mine it uses...
07:09 PM _unreal_: heh
07:09 PM _unreal_: thank you bill
07:10 PM _unreal_: Centurion_Dan, My cnc computer is a 1.6ghz single core netbook with 2gb ram maxed out
07:10 PM _unreal_: heh
07:10 PM _unreal_: My HOME cnc controller
07:11 PM _unreal_: my motion controller is windows based for its interface.
07:11 PM _unreal_: planetcnc controller
07:11 PM _unreal_: got it with a bunch of hardware I ordered long time ago. so figured what the hell
07:12 PM _unreal_: I must say. the controller its self is very nice and they do have linux versions just not for the controller I HAVE that they produce. and naturnally its the ONLY one
07:12 PM _unreal_: oh would you look at that. it stopped di di di di di dinging finally
07:13 PM _unreal_: Centurion_Dan, heh this netbook brings me back to the win98 with 8mb ram days
07:14 PM CaptHindsight: pcw_mesa: I thought that you would just make an equivalent of the analog outs like the 7i77 for the XY2-100 only as digital
07:14 PM cerna: I still don't understand the interest in ISOs instead of simply instaling by means of repository package.
07:15 PM CaptHindsight: pcw_mesa: why a different approach that needs new drivers?
07:16 PM CaptHindsight: cerna: for noobs it's pretty foolproof
07:16 PM CaptHindsight: ISO's vs installing as packages
07:16 PM pcw_mesa: CaptHindsight: no, because of the limited update rate and the relatively high bandwidth of the galvanometers its modeled after the stepgen
07:16 PM pcw_mesa: with acceleration added as well
07:17 PM CaptHindsight: pcw_mesa: so the xy2-100 will work on any fpga card with digital IO?
07:17 PM pcw_mesa: so basically it can extrapolate parabolas from waypoint to waypoint
07:18 PM pcw_mesa: yes
07:18 PM cerna: CaptHindsight: The whole HAL layer is not noob-friendly. I find it fairer to discourage them sooner.
07:18 PM pcw_mesa: I forget how many pins, maybe 4 output and 1 input
07:20 PM CaptHindsight: we have stepgens now
07:20 PM pink_vampire: cerna: did you saw my answer?
07:20 PM CaptHindsight: I'll have to see how the driver needs to work
07:20 PM pcw_mesa: interface register-wise its very close to a standard hardware stepgen with added acceleration register
07:20 PM CaptHindsight: ok
07:21 PM CaptHindsight: pcw_mesa: do you have the xy2-100 posted somewhere?
07:21 PM cerna: pink_vampire: Yes, sorry. Some time passed and was not sure you were still here. So it passes through HAL layer?
07:21 PM CaptHindsight: I'll probably be free to look at it later this month
07:21 PM CaptHindsight: and try to get it running
07:21 PM pcw_mesa: yes its in the current firmware source ( I even mess with it a bit )
07:22 PM CaptHindsight: ok, thanks
07:22 PM pcw_mesa: messed
07:22 PM pink_vampire: cerna: no it is independent controller,
07:22 PM CaptHindsight: I'm working on SVG support for LCNC now
07:22 PM CaptHindsight: for DLP/LCD printers
07:22 PM pcw_mesa: A filter?
07:22 PM CaptHindsight: sync the layer of the SVG to the Z layer of material
07:23 PM cerna: pink_vampire: Ah. I was interested if you have some error routine coupled with it.
07:24 PM cerna: Like pull out of the currest cut to safe position and such.
07:24 PM pcw_mesa: Ahh that would be a missing part for DataPainter support, how do you feed the motion synced data...
07:24 PM cerna: *current
07:24 PM pink_vampire: it is just read bunch of sensors to make sure the machine is healthy
07:25 PM cerna: I am interested in self monitoring of the HAL system. That's the reason why I ask.
07:25 PM pink_vampire: it is working closer to the hardware then linuxcnc, that involve the computer
07:26 PM cerna: *self health monitoring. (I should stop drinking and go to sleep.)
07:26 PM pcw_mesa: CaptHindsight: do you want a bitfile with a xy-100 instance or 2 built in?
07:26 PM pink_vampire: cerna: not sure what do you mean by that, you can push the error signal to linux cnc if you want
07:26 PM cerna: So it is part of the safety relay circuit?
07:27 PM CaptHindsight: pcw_mesa: sure, but no rush
07:27 PM pink_vampire: no, it is more for me, because is is safer to stop the machine manually or finish the job, then just cut the power
07:28 PM pcw_mesa: for what card?
07:29 PM cerna: pink_vampire: For example automatic reaction to arbitrary unexpected inputs. Like this error signal. Or missed real-time constraints. (Move the tool back, stop spindle and move to "safe" position.)
07:29 PM pink_vampire: (Move the tool back, stop spindle and move to "safe" position.) try it with slitting saw
07:30 PM cerna: Of course, we are programmers, so make the reaction situation appropriate.
07:30 PM pink_vampire: also "safe position" is very depend on your setup
07:31 PM gregcnc: CNC machines simple stop on Estop
07:32 PM cerna: gregcnc: Which is in many cases nonsense. And I am not interested only in mill type CNC.
07:32 PM gregcnc: you can't predict what a safe motion would be
07:32 PM pink_vampire: gregcnc: exactly
07:32 PM gregcnc: what if running a t slot cutter?
07:33 PM pink_vampire: or boring a hole in a mill-turn operation
07:34 PM pink_vampire: or drilling with the B axis in 45 deg
07:34 PM gregcnc: E-stop is stop spindle and motion ASAP and that is all. Everything else can be sorted after emergency is over
07:34 PM cerna: Or running infusion pump. That's why I said the reaction should be situation appropriate.
07:35 PM gregcnc: specific needs are well, specific
07:36 PM cerna: Sure.
07:38 PM _unreal_: ok I'm milling my grape leaves
07:38 PM _unreal_: err grape vines
07:39 PM pink_vampire: cerna: the "check for errors' is for those time that the machine is in ON position for half a day, and you don't want to babysit it, so if something is **about** to happen, then you will get this yellow light, it is not necessarily a fatal issue, but it is telling you that you are close to the limit and you need to make sure it is doing what you intended it to do
07:41 PM CaptHindsight: pcw_mesa: sorry, 6i25 would be a safe bet
07:42 PM pcw_mesa: OK I should get to it sometime this week, do you want it combined with a standard config? (maybe put X-Y100 on second connector)
07:42 PM CaptHindsight: pcw_mesa: yes, good idea
07:43 PM CaptHindsight: known good hardware to test against
07:44 PM cerna: pink_vampire: Thank you for explaining. I have something similar with current monitoring in my home.
07:45 PM pcw_mesa: bbl dinner time...
07:45 PM pink_vampire: https://www.youtube.com/watch?v=-kB-BGMXxZc&feature=youtu.be&list=PLp9MhWWMIp3o70MJzBQD0rCjXRUiC4upS
07:45 PM pink_vampire: I need one like that
07:51 PM gregcnc: 6 minutes of near death
07:51 PM _unreal_: LOL pink_vampire I've seen that guy he lives in naples florida
07:51 PM _unreal_: thats south of me
07:52 PM _unreal_: infact I've done work on his boat
07:53 PM pink_vampire: ok, how do I get his phone number? I need to discuss my life priorities with him
07:54 PM _unreal_: his web site....?
07:54 PM pink_vampire: I'm riding a unicycle
07:55 PM pink_vampire: but I think unicycle is so 2019
07:55 PM _unreal_: it... is... 2019
07:55 PM _unreal_: ?
07:56 PM gregcnc: pfft that was January
07:56 PM _unreal_: wow 100,000k lines of ncode and its a 48min mill job
07:57 PM pink_vampire: yeah I know, but I need to think about my 2020 transportation device
08:00 PM _unreal_: inteeresting this controller does not like doing integer math with a scaling off set
08:01 PM _unreal_: same job full size and motors are smooth as silk. but scalled down and certian areas the motors are making studdering move ments. its totaly the controller though.
08:01 PM _unreal_: motion controller
08:02 PM _unreal_: flying over land I hope he has an inflatable crash suit
08:03 PM _unreal_: I'm thinking the 30' off ground at 60mph
08:03 PM _unreal_: not much time for a parachute
08:04 PM pink_vampire: _unreal_: did you tried unicycle on ice?
08:06 PM _unreal_: Thought about it once....
08:06 PM _unreal_: would likely need studded tire though
08:07 PM _unreal_: TI-RE
08:07 PM pink_vampire: no my unicycle is fine
08:07 PM _unreal_: hum
08:07 PM _unreal_: looks cool but my plunge is too deep :(
08:07 PM gregcnc: wait what it the temperature in NY?
08:08 PM _unreal_: gregcnc, likely high 80's to 90's
08:08 PM pink_vampire: it is sooo fun and effortless but not the safest thing I did
08:08 PM _unreal_: its? 92 outside here in south florida
08:09 PM pink_vampire: here is wayy to hot for a winter person like me.
08:09 PM * _unreal_ spend 35+ years in winter
08:09 PM _unreal_: grew up in maine
08:09 PM _unreal_: DONT MISS winter
08:10 PM _unreal_: Though I do now and then wake up with night mares of being back in maine in winter. no joke
08:11 PM _unreal_: maine/new england in summer is nice....! new england area in winter is ;P
08:11 PM pink_vampire: I love winter
08:11 PM pink_vampire: snow ice rain cloudy sky
08:12 PM _unreal_: dont get me worng. give me a powder covered mnt. I'll carve the shi.... out of it but I want winter on my terms
08:12 PM _unreal_: pink_vampire, I like being able to go to the beach jump into the ocean in JAN....
08:13 PM _unreal_: and be worm :)
08:13 PM _unreal_: OCEAN
08:13 PM _unreal_: snorkling etc...
08:13 PM _unreal_: surfing
08:14 PM pink_vampire: not for me
08:14 PM _unreal_: You wouldnt visit summer in the middle of winter?
08:15 PM pink_vampire: the coldest the better
08:16 PM _unreal_: now and then when I get the chance I go to the bahamas. OR I'll go down to the --> Caribbean <---- not cheap
08:21 PM _unreal_: though beingg in the caribbean IS dirt cheap
08:22 PM _unreal_: depending on where you go. you can live fat on $25 a week
08:25 PM _unreal_: pink_vampire, in that video link you posted. at about 2:33 they have the hover toys. using jetskis.. I have a hover board. :)
08:25 PM _unreal_: god just the board is $4k
08:25 PM pink_vampire: link?
08:25 PM _unreal_: not including the hose the coupler
08:25 PM _unreal_: link to...
08:26 PM pink_vampire: ok I see now
08:30 PM _unreal_: I have one of these https://www.bing.com/videos/search?q=water+hoverboard&view=detail&mid=9C94DCD1F4A9843FB6CF9C94DCD1F4A9843FB6CF&FORM=VIRE
08:31 PM Tom_L: looks dangerous
08:31 PM pink_vampire: this is look like epic fun
08:32 PM _unreal_: tisss crazy fun

08:34 PM _unreal_: embeded carbon fiber strands
08:34 PM _unreal_: I built all the jigging to make any kind of design I want
08:34 PM pink_vampire: look cute
08:35 PM pink_vampire: it is design to float?
08:35 PM _unreal_: cute? that thing is HUGE
08:35 PM _unreal_: those probps are 13" each
08:35 PM _unreal_: props
08:35 PM _unreal_: yes
08:35 PM _unreal_: float
08:35 PM _unreal_: I work on boats making something like that water proof for me is easy stuff :)
08:36 PM _unreal_: yay MILLING JOB is done
08:36 PM pink_vampire: what are you milling?
08:39 PM _unreal_: grape vine into a wine bottle holder
08:39 PM _unreal_: saddly looks like ass. milling to deep
08:39 PM _unreal_: I forgot to off set Z when scalling
08:40 PM pink_vampire: do you have a picture of that?
08:40 PM pink_vampire: _unreal_: add it to the ART bin
08:42 PM _unreal_: art bin?
08:43 PM pink_vampire: scrap bin
08:43 PM _unreal_: !!! I have a request... one second let me see if I can find a link to what I'm talking about
08:43 PM pink_vampire: ok
08:46 PM _unreal_: I'm not in linux so I dont know the link. off hand
08:46 PM _unreal_: this will take a min
08:46 PM skunkworks: pink_vampire: did you see https://www.youtube.com/watch?v=YZI7Q7O_PcY
08:47 PM pink_vampire: i that a cnc lathe?
08:48 PM _unreal_: found the website
08:48 PM _unreal_: just need to find the link
08:49 PM _unreal_: found it https://www.osbornewood.com/7510.aspx?position=22&searchGUID=c8ba2828-a2ef-410d-b239-0b29e1d28a49&sortOption=Relevance
08:49 PM _unreal_: wondering if anyone could convert that for me?
08:49 PM _unreal_: stl or dxf
08:49 PM _unreal_: to a mill path. I dont have anything setup right now to generate milling paths in 3D
08:50 PM _unreal_: well 2.5d
08:50 PM pink_vampire: dxf is 2d
08:50 PM skunkworks: pink_vampire: ? the big lathe? yes - mazak
08:51 PM pink_vampire: _unreal_: they alredy give you the stl file
08:51 PM pink_vampire: skunkworks: you are a linux cnc wizard
08:52 PM _unreal_: pink_vampire, I KNOW but I dont have anything setup yet that can generate an NC path with that
08:52 PM _unreal_: I just installed fusion360. no idea how to use it
08:52 PM pink_vampire: just use image to gcode
08:52 PM pink_vampire: but you will need gray scale image for that
08:52 PM _unreal_: I dont have a BW image of that
08:53 PM _unreal_: That site has a lot of great files
08:54 PM pink_vampire: if you have the 3d file
08:54 PM pink_vampire: just use 3d adaptive with ball end mill
08:54 PM pink_vampire: and call it a day
08:55 PM pink_vampire: it is just wood
08:55 PM Tom_L: _unreal_ convert it to what?
08:55 PM Tom_L: oh nevermind
08:59 PM _unreal_: 3d adaptive?
08:59 PM _unreal_: I'm not sure what your talking about?
09:00 PM Tom_L: <_unreal_> wondering if anyone could convert that for me?
09:00 PM _unreal_: My issue is I dont know how to convert an STL to gcode
09:00 PM _unreal_: no clue how
09:00 PM Tom_L: that's not a conversion but generate a toolpath which is a bit more work
09:06 PM Tom_L: stl is a model and you need to generate a toolpath that covers the surface of it
09:06 PM Tom_L: and possibly any roughing passes needed to relieve excess material before the final cut
09:13 PM _unreal_: Tom_L, yep. and I'm trying to make it really small 1" size
09:14 PM Tom_L: once in cad, you would scale all 3 axis to the size you want
09:14 PM Tom_L: most cad packages have a scale feature
09:15 PM pink_vampire: _unreal_: 1" for the whole grape cluster?
09:15 PM Tom_L: fraid so
09:16 PM Tom_L: too small to have any detail left
09:16 PM _unreal_: heh not for my bits
09:16 PM _unreal_: I have 20 degree V bits
09:16 PM pink_vampire: you just need very small end mill or v bit
09:16 PM _unreal_: very long sharp
09:16 PM pink_vampire: there you go
09:17 PM _unreal_: 20 degree 0.3mm tip
09:17 PM pink_vampire: that should make it
09:18 PM _unreal_: very pointy. I know I stabbed my finger just taking them out of the package
09:19 PM Tom_L: you need to know how far you want each cut spaced apart
09:19 PM Tom_L: you want fine detail it should be fairly close but the gcode file will be large
09:20 PM _unreal_: my bits are needles :)
09:20 PM _unreal_: and at 1" thats what one wants
09:20 PM Tom_L: yeah i have engraving bits as well
09:21 PM _unreal_: these one's are 1/8th shank
09:21 PM Tom_L: same
09:21 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/pendant/pendant2.jpg
09:21 PM SpeedEvil is now known as Guest63465
09:21 PM _unreal_: 1/4" flute
09:21 PM Tom_L: i did that lettering with it
09:22 PM _unreal_: nice

09:23 PM _unreal_: huba huba
09:44 PM pink_vampire: https://www.youtube.com/watch?v=lAUEiaPzRGQ no cnc
09:46 PM Tom_L: _unreal_ there is engraving software that may do a decent job on that
09:46 PM Tom_L: i don't use them
09:47 PM Tom_L: f-engrave?
