01:02 AM IchGucksLive: hi all
01:08 AM IchGucksLive: what a beatifull day im off 2 garden BYE till later
01:09 AM Deejay: moin
02:10 AM The_Ball is now known as Guest50921
03:18 AM IchGucksLive: hi asll
03:18 AM IchGucksLive: a sunny day in germany
03:18 AM IchGucksLive: hi Guest50921
03:19 AM IchGucksLive: Guest50921, if you need help ask
03:23 AM IchGucksLive: im off till later
03:59 AM gloops: http://www.archiproducts.com/en/products/cininils/wall-lamp-formala2_264072
03:59 AM gloops: £900 for that..im in the wrong business
04:18 AM bip: Hello
04:19 AM bip: CNC = help for Dell EMC ??
04:19 AM bip: Type Networker
04:24 AM gloops: whats the problem?
04:24 AM bip: hello gloops, only know if
04:24 AM bip: this channel talk about Networker & Restore of DELL EMC :)
04:25 AM gloops: someone might know
04:41 AM enleth: bip: https://en.m.wikipedia.org/wiki/Numerical_control
04:44 AM jthornton: morning
05:18 AM Loetmichel: bip: mope
05:18 AM Loetmichel: nope
05:19 AM Loetmichel: this is about LinuxCNC, a software that is used to control lathes and milling machines and robots
05:20 AM Loetmichel: ... which had to reneame itself from EMC^2 because of a copyright dispute with dell/EMC.
05:25 AM gloops: tbh im probably done with linuxcnc, for the time being anyway, nothing more i need to know, i do find some of the offshoot convos in this channel educational and entertaining though
05:25 AM gloops: this is a place where you can make any general query about cnc
05:26 AM gloops: no strict guidelines or admin, who knows what the purpose of this place is for
05:27 AM Loetmichel: sooo... now that i have a "virgin" sacrificial board on the Routers vacuum table -> http://www.cyrom.org/palbum/main.php?g2_itemId=17088&g2_imageViewsIndex=1 ... LETS MAKE SOME NOISE!!! (and golden glitter :-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=17091&g2_imageViewsIndex=1
05:34 AM gloops: what are you machining/making Loetmichel?
05:34 AM Loetmichel: shielding for a keyboard membrane
05:34 AM Loetmichel: 0.3mm brass
05:35 AM Loetmichel: one sheet below the foil pack, one sheet above
05:36 AM gloops: the brass is sandwiched?
05:38 AM Loetmichel: nope, the keyboard membrane gets sandwiched between the two brass parts
05:39 AM gloops: im just looking sheet brass up, 300x100x.7mm is £5, thats not bad really
05:39 AM Loetmichel: look on the linuxCNC window there you can see how it looks finished ;)
05:40 AM gloops: ah, no i can see it now
05:41 AM gloops: hmm you would need vac table for that yes, would be awkward to hold with clamps, maybe could hold it flat with contact adhesive or double sided tape etc
05:41 AM Loetmichel: yeah, i could
05:41 AM Loetmichel: but it would be very "flappy"
05:42 AM Loetmichel: or i would have to use loads of solvent to get the double sided tape off afterwards
05:42 AM Loetmichel: which is no fun
05:42 AM Loetmichel: vacuum table is best for thin sheet metal
05:43 AM enleth: have you ever machined your own lathe backplate for one of the short-taper spindle nose styles, like DIN 55027?
05:43 AM Loetmichel: nope, sorry
05:44 AM enleth: as far as I understand, taper depth is critical on those as they use both the taper itself and the flange, as opposed to L0 and similar where the exact depth of the taper is not horribly critical (it's long and the thread pulls it in as much as possible, there's no positive stop)
05:44 AM gloops: ive got one sitting right here enleth
05:45 AM enleth: so I'm wondering what the proper procedure is for machining that short taper - if it's too shallow, there's a gap between the back face of the backplate and the front face of the spindle
05:45 AM enleth: but go just a little too far, and it will bottom out face against face, failing to engage the taper
05:45 AM rmu: enleth: machine the taper longer than needed, then face the front until it fits perfectly
05:46 AM enleth: rmu: yeah, sounds like the proper order of operations, it's way easier to correct a face incrementally than it is to do taper correction
05:47 AM enleth: still, the target size window seems to be uncomfortably small
05:47 AM rmu: hmm. rethinking, i got something wrong, let me search how to do it for my EMCO
05:50 AM gloops: you basically need to turn it right
05:51 AM rmu: enleth: you want to machine the part on the chuck, right?
05:52 AM gloops: the one i have, the taper meets at the back and the front, the middle is hollow
05:52 AM Loetmichel: gloops: it looks like that when done: http://www.cyrom.org/palbum/main.php?g2_itemId=16631 ... just without the fail ;)
05:52 AM gloops: you can cut the front of the taper short id say, it will still pull tight on
05:54 AM gloops: clearance back and front, the thread will pull the taper tight, there is also a keyway in the one i have though, which complicates things
05:54 AM gloops: its got to be bang on
05:55 AM gloops: looks very good Loetmichel, my interest is mainly for making door/name plates and so on
05:56 AM Loetmichel: i would use at least 0.8mm sheet brass for name plates
05:56 AM Loetmichel: the 0.3mm stuff is way to thin to not fold over when you do so much as touch it
05:57 AM gloops: yeah so i want to be erring toward 1mm minimum
05:57 AM gloops: i will get a piece anyway and play around
06:02 AM enleth: gloops: well, the reason I am asking is because I am *not* talking about the type secured with a huge threaded collar, those are indeed just pulled in as much as possible and that's it
06:02 AM enleth: gloops: I'm talking about bayonet mount
06:03 AM rmu: enleth: smthg like this? https://picclick.de/FUTTERFLANSCH-100mm-f%C3%BCr-EMCO-Compact-8-DREHMASCHINE-173258300926.html
06:08 AM enleth: rmu: possibly. looks like 55027-2 or 55027-3
06:08 AM enleth: *55027-3 or 55027-4 actually
06:08 AM enleth: the problem with those is that both the taper and the face must be seated completely
06:09 AM enleth: so the diameter of the taper throat where it meets the face is absolutely critical
06:09 AM rmu: i understand, my emco lathe has just that sort of taper on the backplate of the chuck
06:10 AM rmu: so you could either bore the taper a bit oversize, and face until it fits, or do it the other way round :-)
06:20 AM enleth: a major problem is that I only have one lathe
06:20 AM enleth: so it's going to be a pain
06:31 AM rmu: enleth: if the thing you are machining is for your own lathe, mount the plate in the chuck and don
06:31 AM rmu: t dismount it until it fits
06:32 AM enleth: figured as much - I'd have to basically swap the chuck around to check the fit
06:34 AM enleth: and that's not going to be easy either, normally I have to use a hefty bar held in the chuck to dislodge it from the taper after undoing the bayonet mount
06:38 AM enleth: that is, chuck the bar and smack it with a mallet

07:35 AM Beachbumpete1: MORNING LINUXCNC :)
07:35 AM Beachbumpete1: its a rainy crappy day here but hey I'm working so its all good
07:36 AM IchGucksLive: Beachbumpete1, the day is almost gone as lots of ground after the hevy thunderstorms yesterday
07:36 AM IchGucksLive: quite big errosions
07:45 AM Beachbumpete1: Damn that does not sound too good
07:50 AM IchGucksLive: only if you get stuck in deep mud as YOUZ well know
07:50 AM IchGucksLive: Beachbumpete1, howmany hurricans did you gone thrue
07:52 AM Beachbumpete1: two
07:52 AM Beachbumpete1: since we moved back
07:52 AM Beachbumpete1: only one was really worth talking about
07:52 AM Beachbumpete1: lived here for decades before tho and only had one really come close to hitting us hard.
07:53 AM IchGucksLive: ofcause the climate has been bad always
07:53 AM IchGucksLive: we will survive till the end
07:54 AM IchGucksLive: im off
08:00 AM bip: Loetmichel: ty so much for info :)
08:00 AM bip: Around the web #EMC = #*CNC for this reason i asked.
08:00 AM bip: Its ok ^^
08:03 AM rmu: bip: in this context, EMC = Enhanced Machine Controller
08:52 AM JT-Shop-2: .seen philpi
08:52 AM theCockerel: Sorry, I haven't seen philpi around.
08:52 AM JT-Shop-2: .seen phipli
08:52 AM theCockerel: JT-Shop-2: I last saw phipli at 2018-04-23 - 17:21:47 in here, saying :p
09:26 AM IchGucksLive: hi all
09:37 AM IchGucksLive: im off til later
09:55 AM MarkusBec: is it possible to use the 7I84 with the thc?
10:40 AM IchGucksLive: hi
10:40 AM IchGucksLive: MarkusBec, yes you can
10:40 AM hazzy-dev: hello Ichs
10:40 AM IchGucksLive: the mesa provides analog 8bit
10:40 AM IchGucksLive: and also encoder redings on 4 inputs
11:40 AM IchGucksLive: hi
11:45 AM IchGucksLive: im Packing for tomorrows tour on CNC
11:46 AM IchGucksLive: loading the CAR Mercedes with 5 CNC
11:52 AM IchGucksLive: HighInBC, are there some wildfirers at your home area
12:01 PM fragalot: hey
12:01 PM IchGucksLive: ;-)
12:01 PM fragalot: pink_vampire: turns out the surface plate I got was DIN/00 after all :P
12:01 PM fragalot: but since I don't have a stable climate, it doesn't really matter..
12:11 PM IchGucksLive: im off 2 BBQ as we got the major to visit somwhat tonight
12:15 PM Tom_L: KimK, pm theCockerel and .help for directions
12:26 PM SpeedEvil: https://www.reddit.com/user/starman2mars/comments/ Ongoing Q+A by SpaceX manufacturing wonk.
12:29 PM gloops: archivists old boss rang back and gave archivists number, archivist says hes happy for anyone to ring him and was pleasantly surprised someone cared enough to enquire about him, he is very busy atm apparently
12:30 PM SpeedEvil: :)
12:30 PM fragalot: miss0r: ^ told you he was fine.
12:30 PM SpeedEvil: Busy doing stuff he mentioned, or undefined.
12:30 PM fragalot: so talking about disappearances
12:30 PM miss0r: yeah. So I've heard
12:30 PM fragalot: what happened to the captain
12:30 PM fragalot: .seen captainHindsight
12:30 PM fragalot: oh right.. I'm barred from using theCockerel :P
12:31 PM miss0r: captainHindsight.. I saw him a few days ago?
12:31 PM gloops: SpeedEvil i never saw archivist talk about any specific project he was working on, but he did seem to be getting ready for something
12:31 PM miss0r: .seen captainHindsight
12:31 PM theCockerel: Sorry, I haven't seen captainHindsight around.
12:31 PM fragalot: try mrHindsight? (not sure about capitalisation)
12:31 PM miss0r: .seen mrHindsight
12:31 PM theCockerel: Sorry, I haven't seen mrHindsight around.
12:32 PM miss0r: .seen fragalot
12:32 PM theCockerel: miss0r: I last saw fragalot at 2018-04-22 - 19:24:47 in here, saying gloops: it is far more likely that prior to putting it all in the enclosure you had another ground path somewhere
12:32 PM miss0r: That thing is not up to date :]
12:32 PM fragalot: not for me, lol
12:32 PM miss0r: .seen miss0r
12:32 PM theCockerel: miss0r: I last saw miss0r at 2018-04-24 - 17:30:52 in here, saying .seen miss0r
12:32 PM miss0r: indeed :]
12:37 PM skunkworks: 8 6TB drives only took a couple days to build a raid 6 volume..
12:39 PM fragalot: I remember talking to a server admin running some ultra high security & reliability servers
12:39 PM fragalot: rebooting them took 2 weeks
12:42 PM gloops: im finally looking at drawing some simple gear mechanism to demonstrate how gears work, cut from wood, for a teacher who asked me last year, a whole year group has come and gone while ive been mking the router lol
12:42 PM fragalot: gloops: woodgears.ca has a pretty decent gear template generator
12:43 PM gloops: yeah i might get that fragalot, looked at it before it is good, only a nominal charge for the fully working thing
12:43 PM fragalot: right. Time to start taking the RF45 apart
12:44 PM gloops: whatre you doing to it now?
12:58 PM phipli: Pretty : https://www.youtube.com/watch?v=bB01zORIGkA
12:58 PM skunkworks: /dev/md0 33T 855G 31T 3% /media/36tb
12:59 PM CaptHindsight: fragalot_: wasshappining?
01:00 PM Loetmichel: fragalot_: i wouldnt call it "decent"
01:00 PM Loetmichel: i would call it "superb"
01:01 PM Loetmichel: it even can do chain sprockets
01:01 PM Loetmichel: and yes, i bought it ;)
01:01 PM gloops: the online version is ok but only saves as png, if you could save as vectors its straight into CAM
01:05 PM fragalot_: does anyone have a bright idea on how to overcome the "oil vacuum" between a mill table and the ways when sliding it out sideways isn't an option?
01:06 PM SpeedEvil: fragalot_: drill a hole, and squirt air in it
01:06 PM SpeedEvil: Ideally drill the hole ahead of time.
01:06 PM fragalot_: did that through the oil port, worked :P
01:07 PM fragalot_: but the dovetail won't allow it out... Which means I need to move this mill >.<
01:07 PM SpeedEvil: Also, a groovecan work.
01:08 PM Loetmichel: fragalot_: try to put a blow gun with the nozzle flus to the dovetail where it meets with the sled
01:09 PM Loetmichel: somewhere in the middle
01:09 PM Loetmichel: and hope the air pressure is enough to squeeze in between the oil film
01:10 PM fragalot_: Loetmichel: that already worked. Keep up! :D
01:10 PM Loetmichel: ah, i misunderstood
01:11 PM Loetmichel: [20:05] <fragalot_> but the dovetail won't allow it out... <- i thought that way a second part
01:11 PM fragalot_: it is a second part
01:11 PM fragalot_: so i'll have to slide it out sideways
01:11 PM fragalot_: but there is a wall in the way on the left, and a lathe on the right
01:11 PM Rab: gloops, http://geargenerator.com/
01:12 PM fragalot_: . I guess I could move the lathe.. I can just about do that on my own... all 240kg of it.
01:12 PM fragalot_: :P
01:12 PM * fragalot_ runs off to put on his safety boots
01:13 PM gloops: you can however test the meshing in woodgear. then enter the values in inkscape gear generator to get a vector
01:14 PM gloops: that looks pretty good too Rab
01:32 PM hazzy-dev: fragalot_: We're in sync, I just pulled the table on my RF45 :D
02:13 PM gloops: thats a pair of 100 quid specs ruined using them in the garage, another colateral expense for this router
02:14 PM Loetmichel: gloops: specs?
02:14 PM Loetmichel: as in "prescription glasses"?
02:14 PM gloops: reading glasses
02:15 PM gloops: yeah, used them for grinding and just sticking them down anywhere, glass is scratched to hell
02:15 PM Loetmichel: i run thru a pair of prescription glasses (multifocal) a year
02:15 PM gloops: im gonna try those off the shelf ones i think
02:15 PM Loetmichel: because something flys into it or the sander duster scratches it to "milk glass"
02:16 PM * Loetmichel even managed to crack a plastic lens once
02:16 PM Loetmichel: (230mm angle grinder disc exploded and hit the glasses on my nose ;)
02:16 PM gloops: lucky you had them on though
02:16 PM Loetmichel: indeed!
02:17 PM fragalot: Well that's nice
02:17 PM fragalot: the table is off, and i've just measured it as well as I could
02:17 PM Loetmichel: the amount of debris my glasses deflected in my lifetime i would have been blind a 100 times over i think
02:17 PM fragalot: even though the dovetail surface is rough milled, it is accurate within 0.005mm in all dimensions
02:17 PM Loetmichel: so far.. ;)
02:17 PM gloops: *drumroll
02:18 PM fragalot: the saddle is nicely ground on all sliding surfaces,.. but it is atrociously out of square in all directions, lol
02:18 PM fragalot: well, the non-functional front & rear of it are perfectly square.. I guess at least i've got a good reference surface?
02:19 PM Loetmichel: fragalot: http://instantrimshot.com/index.php?sound=rimshot
02:19 PM gloops: my problem is i put safety specs/goggles down and cant find them, so i just pick anything up - reading glasses could probably make an accident worse, broken glass in eye is game over
02:20 PM Loetmichel: gloops: i havent seen real glass glasses for about 2 decades here now
02:20 PM Loetmichel: they are ALL acrylic here in germany
02:20 PM gloops: these are glass, i know because they chipped
02:20 PM Loetmichel: even the multifocal rpescription ones
02:21 PM gloops: so whats the plan fragalot?
02:22 PM fragalot: gloops: having a long think about it
02:22 PM fragalot: measuring that saddle again,.. because I just did it again and now the faces I thought were square aren't
02:22 PM fragalot: however, they are consitent with the offset I had prior to this venture
02:22 PM fragalot: so I must have done something wrong the first time :P
02:23 PM gloops: this is where you want archivist
02:23 PM fragalot: I'd rather have syyl.
02:24 PM gloops: with all his optics and collimators and stuff
02:25 PM fragalot: I think that prior to taking this mill apart I should have made a dovetail measuring jig; at the moment I can't measure that part well on the saddle
02:25 PM fragalot: like an L-bracket with a ground cylinder on one end to measure the dovetail from the top reference surface (eg. the 2 that matter)
02:25 PM gloops: did you initially read the error from cuts the mill was making?
02:28 PM fragalot: yup
02:28 PM fragalot: then trammed in my master square, and that showed the same error
02:29 PM gloops: well, you can bring this square with the gibs cant you?
02:29 PM fragalot: no
02:29 PM gloops: why not?
02:30 PM fragalot: because all the gibs do is tighten the dovetail
02:30 PM fragalot: if the static dovetail is off, you can't correct that with the gibs
02:30 PM gloops: no if the dovetail is off you cant, but i thought you just said that was spot on
02:30 PM fragalot: so anyway, i've just referenced the X dovetail of the saddle with the back "ground" suface i'm using as a reference, and that's good
02:31 PM fragalot: so it's the Y dovetail that's off.
02:31 PM fragalot: I thought it was, but I guess I measured wrong the first time
02:31 PM fragalot: Anyway, more measuring, then i'm going to go have a bath & think about this a bit before I actually start hacking away at the castings :P
02:38 PM Deejay: gn8
02:44 PM fragalot: Right, Y dovetail is off by .01/30mm in X, and 0.01/10 in Z
02:46 PM gloops: a blind man on a lame horse wont spot that
02:48 PM fragalot: for woodworking, fine. for metal? not acceptable.
02:50 PM gloops: dial piece in for either direction change
03:01 PM fragalot: gloops: can't dial a piece in for either direction change..
03:02 PM fragalot: unless I want the piece to not be square, that is
03:03 PM fragalot: looks like they "fixed" some casting porosity in the base.. 4 weld spots on the left dovetail
03:06 PM gloops: i mean mill one direction, then tilt the piece to be square to the other axis for cutting that way
03:06 PM fragalot: that is anything but practical for everyday use
03:08 PM gloops: you wont need this mill when the cnc is built
03:08 PM fragalot: sure I do
03:09 PM fragalot: it has a much larger work envelope, for one thing
03:11 PM gloops: well, you got .2 to 0 to scrape then, both sides
03:12 PM fragalot: can't scrape hole locations
03:12 PM gloops: i mean the dovetails on the mill
03:12 PM fragalot: as for the mill, I will jot down some sketches tomorrow to see if scraping in only the Z will also realign X
04:22 PM gloops: little cnc project there maybe https://www.ebay.co.uk/itm/Amolco-Milling-Machine-attachment-Bench-Top-Base-Myford-Lathe-model-engineer/222943870767?
05:01 PM andypugh: A bit too tiny.
06:09 PM KimK: Tom_L: OK, thanks.

07:40 PM CaptHindsight: https://i.imgur.com/3bqGZGj.gifv dices and staples
08:53 PM enleth: https://photos.google.com/share/AF1QipPh_oYoerLCn6YO5P3fkvPdoZnUPrBguVAEOaJEWaEX3ljNs-GCqpgTrztYJ1IdFQ?key=RDM5YnBjVlJxMjNTQ1VVTDVjd1pkMlFQS2lLckRn
08:53 PM enleth: take a look at that and tell what you think
08:54 PM enleth: I'm looking for a QCTP for the Celtic and I found this guy who makes QCTPs to order, his customers say they're extremely satisfied and it certainly looks very nice
08:54 PM enleth: a larger version: https://photos.google.com/share/AF1QipO9xHthbArJxLB6CeSV0EzvLW0LdQJloZ1nbvVSk4qA_YWme0QMLlTg5Ctc8XA0QA?key=WEFRYzZEQWdLQ0dXYV9vWWNTUzE5ZmxEWTRkWDFB
08:54 PM enleth: mine would be somewhere inbetween those
08:56 PM enleth: the mechanism is kinda unique, I haven't seen any mass-made QCTPs that work exactly like this one
08:56 PM enleth: it's somewhere between a piston type and Aloris in that it uses a piston, but it's a part of the rear (relative to the business end of the tool) dovetail half
08:57 PM enleth: so it does pull the toolholder in and towards the toolpost, getting full contact on the front dovetail, just not on the rear
08:58 PM enleth: I imagine it should be way better than piston type and possibly a little worse than Aloris in terms of rigidity
09:00 PM enleth: the price is very attractive, but I want to be sure there aren't any fundamental flaws in this design that I'm overlooking before I commit to what is pretty much a custom system made to fit my lathe exactly
09:00 PM enleth: so any thoughts on it are welcome
09:06 PM enleth: one thing I'm trying to do now is find out the dovetail dimensions on the mass produced chinese toolholders, to ask the guy to use those particular ones
09:07 PM enleth: if he's making to custom size anyway, it won't hurt to make it a size that conicidentally matches an existing product
09:07 PM hazzy-dev: enleth: The smaller wedge type QCTP have gotten very affordable in the last few years, I used to make my own but not it is not worth it
09:07 PM hazzy-dev: Is there a reason the commertial ones won't work in your app?
09:09 PM enleth: hazzy-dev: well, for one, this guy is actually very slightly cheaper than the Chinese after VAT and customs duties
09:09 PM enleth: and he's local
09:10 PM enleth: so even if his QCTP isn't any *better* than the chinese, but also not worse in any regard, buying from him has the added value of supporting a local self-employed machinist
09:10 PM enleth: for no added cost on my side
09:11 PM enleth: and if, by sheer accident, the holders he makes are interchangeable with the chinese stuff, I'm not even risking any significant sunken cost
09:11 PM enleth: (which is why I'm looking for the dimensions on the latter now)
09:12 PM enleth: so it's mostly a question of "is this design sound and sane"
09:14 PM hazzy-dev: I absolutely understand supporting the local guy! We don't often have that opportunity these days
09:15 PM CaptHindsight: https://photos.google.com/share/AF1QipPh_oYoerLCn6YO5P3fkvPdoZnUPrBguVAEOaJEWaEX3ljNs-GCqpgTrztYJ1IdFQ/photo/AF1QipMWu-0gmjKlCMwARCrceKs495w0TXLttwuFMn0q?key=RDM5YnBjVlJxMjNTQ1VVTDVjd1pkMlFQS2lLckRn
09:15 PM enleth: I know he doesn't harden the dovetails, so they might be prone to work-hardened chips digging in if they get caught in there during a toolchange, but there's a relatively simple remedy for this that's also a general good practice when using a lathe: grab your fucking chip brush and use it
09:15 PM hazzy-dev: The design looks fine to me, it is amazing how low the cutting forces are on a lathe, so unless you are really hogging on a CNC almost anything will do. repeatability would be my main concern, but it looks like it would be good with that design
09:15 PM CaptHindsight: what is it made of?
09:16 PM enleth: C45 steel
09:16 PM enleth: the only part that gets heat treatment is the eccentric cam that actuates the pistons
09:17 PM enleth: the rest is just machined
09:17 PM CaptHindsight: if it works wituh standard holders it's a plus
09:17 PM enleth: manufactured to order, so, well, it's up to me to make sure it does
09:18 PM enleth: I'm quite impressed with surface finish and detail too, at least on those photos
09:18 PM CaptHindsight: unless you get one that not square it seems fine
09:20 PM enleth: have you actually ever seen a QCTP that uses a mechanism like this?
09:20 PM enleth: I guess you could call it a "pawl style", after "piston" and "wedge"
09:26 PM Lcvette: hello
09:26 PM Lcvette: how is everyone tonight?
09:28 PM Lcvette: had a Mesa 7i77 question if there are any on who might help
09:28 PM enleth: OK, I found a single reference to a similar design, referred to as "Colchester method", here https://johnfsworkshop.org/home/processes-links/processes-removing-metal/links-to-pages-about-turning-and-the-lathe/lathe-toolholding-links/lathe-toolholding-quick-change-tool-holders/
09:28 PM enleth: but it's weird, with the pawl on the front dovetail - doesn't seem to make much sense really
09:28 PM enleth: Lcvette: ask away
09:29 PM Lcvette: wanted to verify on the Vfield on TB2, do i need to run my 24v+ to pin 5 WIN or any of the VField 1-4?
09:30 PM Lcvette: not sure if by logic I/O it meant special function
09:30 PM Lcvette: other than typical relay activation and what not
09:31 PM enleth: ugh, I'm not around my mill to check how exactly it's wired, let me take a look at the manual and maybe I'll remember
09:32 PM Lcvette: hahaha... yeah im wiring mine now and even though i drew a nice schematic for it.. when i got to that part I caught that terminal 5 had a different designation in the manual than 1-4.. figured i better ask
09:32 PM enleth: and I'm not really sure I understand the question clearly
09:33 PM Lcvette: ok sorry
09:34 PM Lcvette: TB2 where you run power for the field
09:34 PM Lcvette: mine is going to be a 24vdc supply,
09:34 PM Lcvette: ground goes to common, 24+ goes to ____?
09:35 PM Lcvette: Ground goes to TB2-8, +24 goes to TB2-?
09:37 PM enleth: to any VFIELD, TB2-1 to TB2-4
09:37 PM enleth: if you have W1 set to the left position, you don't have to wire VIN (TB2-5)
09:38 PM Lcvette: at first glance i thought TB2-5 because it says VIN, but it says something about logic and wasn't sure if that meant it was a special voltage in for something specific
09:38 PM Lcvette: ok cool
09:38 PM enleth: mine is definitely wired like this
09:38 PM Lcvette: ok
09:38 PM Lcvette: great
09:38 PM Lcvette: mine is set that way and im on TB2-1
09:38 PM Lcvette: sweet, thank you!
09:38 PM enleth: Lcvette: in short: you *can* provide a separate logic power supply on TB2-5 with W1 set to the right position
09:38 PM enleth: but you don't *have* to
09:38 PM Lcvette: gotcha
09:38 PM enleth: the manual provides one reason to do this
09:39 PM Lcvette: and that would be to use some of the I/O's in a different manner correct?
09:39 PM Lcvette: i read something about it but it went over my head
09:39 PM enleth: so that you have a controlled error condition if you lose VFIELD - field IO logic still runs on VIN and reports a well-defined error
09:39 PM Lcvette: gotcha
09:39 PM Lcvette: ok
09:39 PM enleth: if you use shared power, field logic just dies and drops off the serial bus
09:40 PM Lcvette: ok that isn't a problem in my situation
09:40 PM enleth: I think in practice, the first situation is recoverable without a LinuxCNC restart, and the latter isn't
09:40 PM enleth: but I might be mistaken
09:40 PM enleth: if I'm not, this could be important if your e-stop cuts field power as well
09:41 PM Lcvette: my ATC is the only thing that would be concerning if the field died
09:41 PM enleth: it would be stupid to have to restart LinuxCNC on e-stop
09:41 PM Lcvette: but then it wouldnint move at all since the whole thing is operated by it so..
09:42 PM Lcvette: gotcha
09:42 PM enleth: oh, and there might be some noise-related considerations if your 24V is very messy, noisy and spiky from misbehaving inductive loads
09:42 PM Lcvette: cool
09:43 PM Lcvette: ok, then I will leave it as is for the time being and revist it after the rest is finished if i run into any inconveniences once completed
09:43 PM Lcvette: thank you very much enleth
09:43 PM enleth: no problem
10:34 PM SpeedEvil is now known as Guest33233
10:42 PM hazzy-dev: enleth: I had always wondered in what scenario it would be advantageous to have a separate logic power, but your explanation makes perfect sense
10:44 PM hazzy-dev: I have been resined to restarting LCNC after a e-stop, but I know how to prevent that. Hurray!
10:48 PM CaptHindsight: hazzy-dev: know anyone that does cryogenic grinding/milling for particle reduction, not machining?
11:01 PM hazzy-dev: CaptHindsight: No I don't :(
11:01 PM hazzy-dev: First and last I heard of cryomilling was for about 4 min in a very boringly thought materials class in 2014 :D
11:02 PM hazzy-dev: What are you milling? Pigment?
11:25 PM CaptHindsight: nah pigments don't need cryo
11:26 PM CaptHindsight: polymers need cryo
11:26 PM CaptHindsight: hazzy-dev: ^^
11:29 PM CaptHindsight: https://en.wikipedia.org/wiki/Cryogenic_grinding
11:29 PM theCockerel: [WIKIPEDIA] Cryogenic grinding | "Cyrogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere..."
11:30 PM hazzy-dev: There was a 50-50 for it to be pigments or polymers, and a chose pigments, dang it
11:30 PM hazzy-dev: :)
11:30 PM hazzy-dev: Hey, thats nice!
11:30 PM hazzy-dev: Good Cockerel
11:31 PM CaptHindsight: also biomaterials
11:33 PM * hazzy-dev is still waiting for the wiki page to load
11:34 PM hazzy-dev: at&t uverse it the worst ISP
11:34 PM MarcelineVQ: I know comcast customers that would fight you on that claim hehe
11:34 PM CaptHindsight: business comcast is already getting slower
11:35 PM hazzy-dev: jut got the text, waiting on the images now
11:35 PM CaptHindsight: I've noticed a slowdown here for first page loading
11:35 PM CaptHindsight: downloads are still >60mb/s continuous from fast servers
11:36 PM hazzy-dev: This is a business line, and it just sucks, and they claim they can't give use any better
11:36 PM hazzy-dev: We had a 4+ hr outage this afternoon
11:36 PM CaptHindsight: net neutrality ended yesterday
11:36 PM CaptHindsight: the att contractor snapped our line a few weeks ago
11:37 PM CaptHindsight: they put a new one in and didn't check when they hooked it up...
11:38 PM CaptHindsight: the signal level was too high so all the amps in the building were overloaded, so SNR was terrible
11:38 PM CaptHindsight: was dial up speeds for a day until I told them what was wrong
11:39 PM hazzy-dev: They don't have enough lines to serve our street, so when we had three lines at the office they would only ever have two working , lol
11:40 PM CaptHindsight: and our are underground
11:40 PM CaptHindsight: the Comcast person in charge of marking the lines didn't do it correctly
11:40 PM hazzy-dev: That is terrible
11:41 PM CaptHindsight: I talked with his supervisor at it looked like he just made up where they were with his marking paint
11:41 PM CaptHindsight: at/and
11:41 PM hazzy-dev: Sometimes it is amazing that it workes at all considering what a mess the whole system is
11:41 PM CaptHindsight: they were all upset
11:43 PM CaptHindsight: I made friends with the techs so they spent 2 hours going back to the fiber 1/4 mile away and adjusted every amp in between
11:43 PM CaptHindsight: they were never instal;led properly
11:43 PM CaptHindsight: or adjusted
11:44 PM CaptHindsight: so now I guess we have ATT fiber as a second ISP
11:44 PM CaptHindsight: not sure what the rates or service is like
11:46 PM CaptHindsight: heh, but I talked with the neighbors and they said that Comcast wanted to charge them all $100 for a service call that day
11:47 PM CaptHindsight: so they fuck up and want to charge you to fix it
11:48 PM hazzy-dev: about 6 months ago a at&t rep came by and offered to give us fiber for less than we were paying for copper, we said sure
11:48 PM hazzy-dev: When the techs came out to do the set up they said, sorry, but we don't even have fiber in the area, but we'll upgrade your router
11:49 PM hazzy-dev: so we got a new router and got the rates lowered, but no fiber
11:49 PM hazzy-dev: they just say stuff, and have no clue
11:49 PM CaptHindsight: sounds about right
11:50 PM CaptHindsight: I'm surprised they didn't pretend to give you fiber
11:50 PM CaptHindsight: or make you "fiber ready"
11:51 PM CaptHindsight: well the crappy treatment seems to be getting everyone well trained to put up with being treated like crap
11:53 PM CaptHindsight: we came across a guy today on a trail that was attacked by a dog up the trail, he didn't want to report the attacker since he "didn't want to be a dick or nothin"
