[00:00:06] <naja452> I think
[00:01:08] <naja452> There is these also, they seem to effect how level the bed is
[00:01:11] <naja452> http://imgur.com/eHqiNgL
[00:01:25] <_methods> those bolts loosen so you can adjust the head
[00:01:29] <naja452> But I don't know if that's what theyre for

[00:04:32] -!- chris_99 has quit [Quit: Leaving]
[00:06:12] <naja452> I'll have to try to loose those bolts and nudge it over, i don't have a wrench that big currently.
[00:08:16] <naja452> The head is also out of tram from frobt to back. But the head doesnt swivel on the axis.
[00:09:23] <enleth> naja452: I've got a rigid ram bridgeport, from what I learned till now, you just kind of loosen it up a *little* bit and tap it with a rubber mallet or something
[00:09:53] <enleth> naja452: if the range provided by this type of "adjustment" is too narrow to correct the problem, it's not in the head tram but in the bed, or your machine is FUBAR
[00:10:27] <enleth> or at the very least beyond whatever repair you can do without scraping/grinding/fitting things
[00:12:44] <enleth> naja452: there will be some movement from re-tightening of the bolts too, you'd have to see if it's repeatable
[00:12:56] <naja452> Ok. I'll see what i can do with the head.
[00:13:09] <naja452> Any consensus on what does grub screws above the ways are?
[00:13:41] <enleth> those are bearing blocks, right?
[00:13:50] <naja452> I would assume so
[00:13:57] -!- koo8 has quit [Ping timeout: 250 seconds]
[00:14:40] <naja452> I can get close ups if they would help, i'm not extremely familiar with the hardware.
[00:15:10] <enleth> are those linear ball bearings?
[00:15:55] -!- uwe_ [uwe_!~uwe_@dslb-088-067-183-148.088.067.pools.vodafone-ip.de] has joined #linuxcnc
[00:16:15] <naja452> http://imgur.com/zoLPImb
[00:16:16] <naja452> Yes
[00:16:49] <enleth> ah, there is a slit between the part where the screw is and the actual bearing block
[00:17:34] <enleth> or so it looks on the last photo
[00:18:16] <naja452> Yeah, there's a slit on either side,
[00:18:19] <enleth> so that srew would compress the bearing
[00:18:26] <enleth> I think
[00:18:47] <enleth> but it doesn't look directly related to bed leveling
[00:19:27] <enleth> to be honest though, I have no experience whatsoever with such a design
[00:19:59] <enleth> in fact, I've never seen a cast iron mill with round bar guides instead of ways
[00:20:47] <enleth> it looks funny
[00:21:08] <naja452> Yeah, looking at all of the documentation I found it originally had box ways.

[00:22:36] <enleth> who would do such a conversion?
[00:22:38] <naja452> http://imgur.com/hCRk37P
[00:22:58] <naja452> In this pic you can see whoever modified it lead to big plates on to the box weighs and then put the round bar platform on top of it.
[00:23:56] <enleth> so that orange slab is not even a part of the original mill?
[00:24:30] <naja452> Not per the original manual its not
[00:25:36] <enleth> well, good luck with that, it's going to be fun
[00:26:15] <enleth> with bearing blocks milled into solid hunks of cast iron there's little room for adjustment
[00:26:28] <naja452> Yeah, it has been so far. I'm not ready to give up on it, got it for $500 scrap. I think it'll be worthwhile
[00:26:34] <andypugh> Are those round-bar ways or hydraulics?

[00:26:46] <enleth> maaaaybe if you shim the bar supports
[00:26:56] <enleth> but that will easily lead to bending
[00:27:06] -!- morbo [morbo!~morbo@dyn-222-172.hrz.uni-kassel.de] has joined #linuxcnc
[00:27:30] <andypugh> Ignore that last question I can see the linear balls slides.
[00:27:38] <enleth> I mean, you'd have to use a tapered shim that narrows down to less than paper thin
[00:27:47] <andypugh> Any change the ball slides are in eccentric housings?
[00:28:17] <naja452> I'm not sure what you mean by that.
[00:28:39] <enleth> oh, and the Y axis slides are set directly on cast iron too, nothing to shim there

[00:28:56] <naja452> I'm changing networks I may lose connection for a minute or two.
[00:29:15] <enleth> only the X axis slides look a little like off-the-shelf supported ground bars
[00:29:16] <andypugh> Well, does it help if I type it without the typo? “Any chance that the ball slides are in eccentric housings”

[01:01:05] <trentster> Any suggestions of a good bit to use for surface engraving acrylic (not cutting) ?
[01:01:39] <PetefromTn_> I use carbide single flute engravers for plastic, aluminum, steel etc.
[01:01:51] <trentster> My intended use case is for led illumination of the etching
[01:02:11] <PetefromTn_> yeah I have made edge lit signs before myself
[01:02:54] <PetefromTn_> https://www.youtube.com/watch?v=7aVzdecIVUg
[01:03:22] <trentster> PetefromTn_: thanks looking
[01:03:50] <PetefromTn_> I got my bits from bitsandbits.com I think it was
[01:04:08] <PetefromTn_> https://bitsbits.com/index.php?main_page=page&id=8
[01:04:20] <trentster> This is what I made for my kid the other day, used a vbit for the carving and I am not really happy with the results https://twitter.com/trentster/status/672052007516024832
[01:05:08] <PetefromTn_> honestly it looks pretty nice to me..
[01:05:33] <trentster> yeah but if you look at the tree trunk you can see the engrave is messy
[01:05:41] <PetefromTn_> those carbide single flutes make a clean cut
[01:06:02] <PetefromTn_> I use a .020 tip
[01:06:15] <PetefromTn_> and stepover half in pockets
[01:06:17] <trentster> yeah but they can not give you detail that you need for tight sharp toolpaths
[01:06:58] <PetefromTn_> well they sell many different diameters.
[01:07:19] -!- Loetmichel has quit [Ping timeout: 260 seconds]

[01:07:26] -!- Loetmichel [Loetmichel!~cylly@p54B112E8.dip0.t-ipconnect.de] has joined #linuxcnc
[01:07:35] <PetefromTn_> I chose the .020 because I cut metals often with it and need it to last and hte .020 cuts decent in it without breaking at every turn
[01:07:36] <trentster> I havent made one using rgb leds yet
[01:07:40] <PetefromTn_> thanks
[01:08:01] <_methods> hehe i made one with those rgb leds
[01:08:01] <PetefromTn_> that thing is amazingly bright
[01:08:13] <_methods> i'll have to find the video one sec
[01:08:15] <PetefromTn_> I mean it lights up the whole room easily
[01:09:53] <trentster> PetefromTn_: have you seen the $2 led controllers - I use them for these little signs they have all kinds of different modes, 5 brightness levels and can do pulses and strobes etc. Not reccomended for epileptics tho
[01:10:14] <PetefromTn_> no I have not
[01:10:19] <trentster> Do you have a tight high res shot of the sign so I can see what your engrave lines look like?
[01:10:45] <PetefromTn_> I used one of those remote controlled ones with the multi color and it has fades, strobes, and about everything else...
[01:11:01] <PetefromTn_> hang on I will look
[01:11:56] <trentster> PetefromTn_: this is what I use they work great : http://www.banggood.com/LED-Controller-Dimmer-For-3528-5050-Sinlge-Color-Car-LED-Strip-DC12V-p-79156.html
[01:12:10] <PetefromTn_> http://i.imgur.com/06RXzPR.jpg
[01:12:11] <trentster> just pop it inline between wall wart on the sign
[01:12:45] <PetefromTn_> that looks interesting and cheap
[01:12:46] <_methods> https://www.dropbox.com/s/go6krw2s0luwjc8/2014-05-01%2000.09.32.mp4?dl=0
[01:12:50] <_methods> lol
[01:13:01] <_methods> made one to harass my buddy james
[01:13:02] <PetefromTn_> does it allow multicolor modes?
[01:13:26] <trentster> no its not RGB, but I think you can buy RGB ones, may be a few $ more
[01:13:34] <_methods> ws2812
[01:13:42] <_methods> are the adressable leds
[01:13:55] <_methods> apa102's are addressable also
[01:13:59] <Tom_itx> zeeshan|2, 2.38Gb
[01:14:02] <_methods> but they are newer and more expensive
[01:15:22] <trentster> PetefromTn_: thanks for the photo its slightly out of focus so I can not see the cuts properly, but it does look way better than mine ;-)
[01:15:49] <PetefromTn_> sorry it is the best one I had LOL
[01:15:58] <trentster> no worries
[01:16:03] <trentster> :-)
[01:16:13] <_methods> i used the ws2812's for my xmas tree also
[01:16:17] <PetefromTn_> it was cut with that .020 tip at 5500RPM and about 10IPM I think it was
[01:16:35] <_methods> you can get a 5m strip of 60 led/m for like $40
[01:17:34] <trentster> _methods: lol - is that sign for your desk to annoy your buddy or for your buddies desk?

[01:18:28] <trentster> I hope he has not promoted it to the dumpster after you left ;-)
[01:18:55] <_methods> hahah no he got me back with one better
[01:19:13] <_methods> let me see if i can find that
[01:19:37] <PetefromTn_> thats pretty cool man
[01:19:46] Protractinium is now known as Praesmeodymium
[01:19:48] <trentster> PetefromTn_: I will give your tooling a try, only issue is my spindles lowest rpm is 8000 - but I can play with feeds and speeds to get emulate your result
[01:20:12] <PetefromTn_> faster is better generally for plastic
[01:20:28] <PetefromTn_> sharp bits and high speeds until you start to melt shctuff
[01:20:48] <PetefromTn_> 6k is the max spindle speed on my VMC so I used what I had.
[01:21:26] <PetefromTn_> I actually built a nice heavy duty router spindle mount for the machine in case I need 30k RPM for stuff like that in the future
[01:21:34] <PetefromTn_> I have only used it once so far LOL

[01:21:53] <trentster> my spindle range is not ideal for milling metals unfortunately 8k-24k only
[01:22:17] <PetefromTn_> if it has the torque that is nice for aluminum anyway

[01:22:51] <trentster> *trentster secretly hopes Santa will put an industrial mill in his xmas sock ;-)
[01:23:23] * PetefromTn_ feels the same way about a bigass slantbed CNC lathe with live tooling ;)
[01:23:46] <_methods> hahah
[01:23:58] <_methods> santa will bring that right after you get your current lathe running
[01:24:03] <_methods> and your toolchanger working
[01:24:16] <PetefromTn_> BITE ME ;)
[01:24:20] -!- zeeshan|2 has quit [Ping timeout: 245 seconds]
[01:24:21] <_methods> hahahhaha
[01:24:30] <trentster> PetefromTn_: I have not cut anything with it yet unfortunately only mounted it yesterday to replace 400W one, this one is 2.2KW and still busy finding elegant way to neaten up the water hoses.
[01:24:30] <PetefromTn_> I am working on the lathe tho man
[01:24:49] <PetefromTn_> this is a CNC router I assume
[01:24:54] <_methods> that's how it always works
[01:25:05] <_methods> once you get some crazy shit working something better drops in your lap
[01:25:15] <trentster> PetefromTn_: yup its a router
[01:25:47] <PetefromTn_> _methods honestly man I will be VERY happy with this lathe once It is working I think.
[01:25:59] <_methods> hell yeah
[01:27:43] <trentster> I would be happy with a manual lathe at this point, since I dont have any ;-)
[01:29:03] <PetefromTn_> so would I ;)
[01:30:05] <_methods> a manual lathe is something i think you should always have around
[01:30:18] <_methods> especially for one off stuff
[01:30:24] <PetefromTn_> man you are on a roll today huh
[01:30:40] <_methods> well that wasn't aimed at you lol
[01:30:43] <PetefromTn_> LOL
[01:31:06] <_methods> i feel your pain
[01:31:11] <_methods> being latheless is hell
[01:34:02] <duc> Not sure what is worse. Latheless or millless
[01:34:07] -!- lair82_ has quit [Ping timeout: 250 seconds]
[01:34:15] <_methods> you can mill on a lathe in a pinch
[01:34:38] <_methods> so i'd rather have a lathe than a mill
[01:35:02] <_methods> and grind
[01:35:08] -!- maurris has quit [Client Quit]
[01:35:24] <PetefromTn_> I have done it several times lately LOL
[01:36:12] <_methods> hypothetically if you had to choose one over the other
[01:36:18] <_methods> lathe wins
[01:36:34] <PetefromTn_> you think so?
[01:36:38] <_methods> yeah
[01:36:43] <_methods> you can make a mill with a lathe
[01:36:49] <_methods> you cant make a lathe with a mill
[01:36:56] <andypugh> trentster: My spindle range is not ideal for milling metals either, 45 to 1000 rpm. I am not sure which side of wrong is the place to be. At least I can increase bit size until the speed is right.
[01:37:04] <PetefromTn_> I have milled with a lathe and it is more complicated than turning on a mill
[01:37:24] <_methods> i guess you can go both ways
[01:37:31] <PetefromTn_> and less capable really
[01:37:40] <_methods> i've turned stuff in spindle
[01:37:43] <_methods> on mill
[01:37:45] <_methods> just to try it
[01:37:49] <duc> Mill all the way for me
[01:37:54] <andypugh> I would give away my mill before my last lathe.
[01:38:14] <_methods> andy speaks
[01:38:20] <andypugh> I think because I much more enjoy lathe work than mill work.
[01:38:37] <PetefromTn_> I find lathe work therapeutic and calming
[01:38:49] <andypugh> Indeed. And this is all a hobby for me.
[01:38:50] <_methods> except chasin threads
[01:38:53] <PetefromTn_> I am hoping that CNC lathe work with be similar
[01:39:09] <_methods> too stressful for me
[01:39:21] <andypugh> I have a lathe as a front-room ornament. :-)
[01:39:31] <_methods> you have that beautiful rivet right?
[01:39:35] <andypugh> Yes
[01:39:38] <_methods> FU
[01:39:39] <PetefromTn_> andypugh there is someone local selling that lathe here LOL
[01:39:39] <_methods> lol
[01:40:04] <andypugh> A Rivett is a joy to use.
[01:40:05] <_methods> i'd love to have one of those
[01:40:34] <andypugh> Every adjustment is a little lever, the only tool you need at all is the chuck key.
[01:40:50] <_methods> beautiful machines
[01:40:54] <trentster> Are most decent lathes all 3-phase power?
[01:41:05] <_methods> yeah
[01:41:09] <_methods> real industrial stuff
[01:41:17] <PetefromTn_> honestly my 12x36 asian was single phase and it was quite capable
[01:41:22] <andypugh> So it’s just flick, flick, twist to re-set for a different cut. And that includes tool height and angle.
[01:41:35] <_methods> just get a vfd
[01:41:46] <_methods> and pick up all the 3ph stuff you want
[01:43:05] <andypugh> I don’t know about the US, but in the UK 3-phase is 440V and domestic is 240V, so you need to check that the motors are rewirable.
[01:43:18] <duc> Now a manual mill is relaxing to me. Cnc. Eh
[01:43:54] <trentster> _methods: yeah, only issue is ex industrial stuff over here where I live is like hens teeth - almost impossible to find, and when you do its generally ridiculously priced
[01:44:20] <andypugh> Though when I bought a mill with a 3-terminal 440V motor it only cost me £50 to have a motor repair place dig out the star point and reconfigure it for me. You might be able to do it yourself for less, but by the time you have got the right string, tape, laquer etc, maybe not.
[01:44:21] <trentster> you guys are lucky, you may even get items for next to nothing that people just want removed
[01:44:39] <_methods> yeah we got an old takisawa lathe for free one time
[01:44:47] <_methods> they just wanted it out of the place
[01:44:56] <_methods> eaton gave it to us
[01:44:57] <_methods> lol
[01:45:04] <_methods> takisawa tc-3
[01:45:05] <PetefromTn_> where are you located?
[01:45:07] <trentster> _methods: I hate you! ;-)
[01:45:17] <_methods> we got rid of it years ago
[01:45:30] <trentster> PetefromTn_: I am in Melbourne, Australia
[01:45:36] <PetefromTn_> ah
[01:45:49] <PetefromTn_> surely there must be SOME industry there no?
[01:46:25] <trentster> Yeah but population is only 21 Million people across a huge geographic area
[01:46:27] <PetefromTn_> I was contacted by a fellow from New Zealand that has the same Cincinatti Arrow 500 that I have
[01:46:35] <andypugh> Australia seems to be the place to pick up 19-teens solid tyred vehicles. Machine tools, less so.
[01:46:37] <trentster> which equates to stuff being hard to find and sought after.
[01:46:49] <zeeshan> trentster: what
[01:46:53] <zeeshan> canada has a bit more
[01:46:56] <trentster> Heck there are chinese cities alone with bigger populations then the whole of Australia
[01:46:56] <zeeshan> and we're way bigger than you :-)
[01:46:57] <_methods> no one wants to ship to the land down under
[01:47:04] <_methods> everything wants to kill you there lol
[01:47:24] <_methods> crazy ants and snakes
[01:47:25] <PetefromTn_> shit there are Chinese cities that have larger populations than about anywhere LOL
[01:48:15] <trentster> _methods: yeah there are shells on the beach here that will kill you if they nip you.
[01:48:29] <PetefromTn_> are you shitting me?
[01:48:45] <_methods> they got those crazy jellyfish that you can't even see
[01:48:49] <_methods> irukanji
[01:48:51] <_methods> or whatever
[01:48:53] <PetefromTn_> I know there are huge sharks, crocodiles, and crazy spiders
[01:48:59] <trentster> its an interesting place, but the reality is most folks live in cities, very much like any US one - without the dangerous pests that go bump in the night :-)
[01:49:01] <PetefromTn_> box jellies
[01:49:18] <_methods> the irukanji are worse than that i hear
[01:49:23] <trentster> yeah I am not afraid of the big things, its the small stuff that scares me
[01:49:34] <_methods> so small you can't even see them
[01:49:52] <_methods> yeah i'd love to go i've never been to au
[01:50:03] <PetefromTn_> I would love to visit New Zealand
[01:50:04] <trentster> like the wallnut sized jellyfish in queensland that can stop your heart with nuro venom and so small you dont even know you have bumped into it while swimming
[01:50:31] <PetefromTn_> yeah that is the box jellies I think they are clear and very tiny
[01:50:38] <_methods> https://en.wikipedia.org/wiki/Irukandji_jellyfish
[01:51:06] <_methods> yeah box
[01:51:10] <PetefromTn_> sounds like the same animal
[01:51:17] <_methods> didn't know that name
[01:51:27] <_methods> i thought the box jellies were bigger
[01:51:33] <trentster> _methods: yeah the irukanji - apparently they have the fastest projectile weapon in nature, the little darts they fire out have insane acceleration
[01:51:37] <_methods> but they have those ringed octopi too
[01:52:28] <PetefromTn_> yeah that's scary man. and I love swimming and snorkeling LOL
[01:53:11] <trentster> PetefromTn_: New Zealand is truly beautiful, its so beautiful you kind of have to rub your eyes as you go round the next corner, we did a ship cruise of New Zealand a few years back it was amazing
[01:53:38] <PetefromTn_> that is what I hear
[01:53:54] <PetefromTn_> one of the wonders of the world from what I have seen in pictures
[01:54:08] <_methods> wow they had some terrorist knifin people on the subway in london now?
[01:54:11] <trentster> Yeah thats not the manly way to go out - you don't want on your tombstone - he was taken out by a walnut sized jellyfish
[01:54:11] <PetefromTn_> they filmed the Lord of the Rings series there and quite a few other movies
[01:54:24] <trentster> Eaten by a great white I could handle :P
[01:54:48] <PetefromTn_> shit I don't like either option too much LOL
[01:54:56] <trentster> ahahaha
[01:55:43] <Jymmm> PetefromTn_: lets see one of these "bad" photos you took
[01:56:08] <_methods> oh snap there goes the neighborhood
[01:56:14] <_methods> Jymmm in da house
[01:56:36] <PetefromTn_> huh?
[01:56:41] <trentster> yeah the cruise first stop was "mayford sound" the place where one of the lord of the rings movies ends, the place where they sail under the giant status legs.
[01:56:50] <_methods> Jymmm wants your nude photos
[01:57:01] <trentster> It has to be seen to be believed.
[01:57:07] <PetefromTn_> _methods well he can keep wanting...
[01:57:13] <_methods> hahahhah
[01:57:26] <PetefromTn_> statue>
[01:57:38] <trentster> Lol - what goes on below decks - stays below decks
[01:57:42] <PetefromTn_> I wonder how much a trip there would run?
[01:57:53] <_methods> to see Jymmm ?
[01:57:56] -!- sumpfralle [sumpfralle!~lars@erina.opennet-initiative.de] has joined #linuxcnc
[01:57:58] <_methods> probably cheap
[01:58:12] <PetefromTn_> I understand you spend a full day in the plane LOL
[01:58:17] <_methods> hahahahha
[01:58:32] <trentster> PetefromTn_: you can find cruise specials suprisingly cost effective - and one of the best vacations - you have to think about nothing
[01:58:49] <PetefromTn_> nothing but the ship sinking ;)
[01:59:09] <PetefromTn_> or catching some foreign disease from the food....
[01:59:11] <_methods> jellyfish and great whites all over your ass
[01:59:11] <trentster> I warn you you will definitely put on a few pounds by the end of the trip, they have gourmet food available on the ship almost 24/7 included in the price.
[01:59:15] <PetefromTn_> or
[01:59:16] <Tom_itx> PetefromTn_, my friend went down there in 14 flights including the chopper ride while there
[01:59:16] <PetefromTn_> or...
[01:59:42] <trentster> The food is normally always US food, at least it was on my cruise which was a US cruise line
[01:59:44] <PetefromTn_> trentster I like the free food thing....a lot
[02:00:09] <PetefromTn_> a cruise to NZ from here would be a couple months I think LOL
[02:00:09] <_methods> you better go now in case trump becomes president
[02:00:14] <trentster> our ship even had a 24 hour Sushi bar - which became "my preciousssss" :P
[02:00:17] <_methods> and you can't travel anywhere abroad anymore
[02:00:26] <Tom_itx> trentster, what line did you use?
[02:00:37] <PetefromTn_> my wife says we aren't going nowhere abroad LOL
[02:00:44] <trentster> PetefromTn_: you fly out to Sydney - the cruise starts there generally.
[02:00:50] <Tom_itx> those boats are pretty awesome
[02:00:53] <trentster> Our cruise included Tasmania
[02:00:55] <PetefromTn_> damn that would be some trip
[02:01:03] <trentster> which is enroute to NZ
[02:01:07] <Tom_itx> 14 storries
[02:01:55] <Tom_itx> 2 weeks?
[02:02:36] <trentster> Tom_itx: we used these guys http://www.celebritycruises.com/
[02:03:21] <trentster> but a tip never book a cruise direct with a cruise line always go via a cruise discount specialist you can get prices 50-70% discounted
[02:03:23] <PetefromTn_> woah you can SAVE $1250 LOL
[02:03:33] <Tom_itx> you can find reasonable ones
[02:03:58] <Tom_itx> alaska is usually between 7-11 day
[02:04:39] <andypugh> If anyone is bored, I spent this evening updating my blog.
[02:05:02] <Tom_itx> apparently we are.. we're discussing cruises
[02:05:18] <andypugh> Taking the lathe apart
[02:05:19] <andypugh> http://bodgesoc.blogspot.co.uk/2015/12/holbrook2.html
[02:05:20] <andypugh> Then some CAD design and pattern-making for new parts

[02:06:52] <Tom_itx> have you gotten parts from the 2nd link molds yet?

[02:07:29] <PetefromTn_> you sure take on some coplex projects man
[02:07:34] <andypugh> I will probably collect via a friend this weekend
[02:07:35] <PetefromTn_> complex
[02:09:41] <trentster> PetefromTn_: I just checked what we paid, for a 2 week cruise we paid $4200 USD - this was Dec 2011
[02:10:00] <trentster> That was for 3 person family combined
[02:10:13] <trentster> Specials = value :-)
[02:10:22] <Tom_itx> you can get 5-7 day for ~300 a head usually
[02:10:46] <Tom_itx> we usually drive to Galveston and go out
[02:10:51] <Tom_itx> or NewOrleans
[02:11:45] <PetefromTn_> 2 weeks for 3 people $4200 bucks...
[02:12:01] <trentster> yup
[02:12:16] <trentster> obviously we had to pay for plane tickets on top of that
[02:12:20] <PetefromTn_> I guess that is not terrible considering what is entailed
[02:12:22] <Tom_itx> PetefromTn_, plan a land vacation for that cost
[02:12:25] <trentster> but it was a local flight
[02:12:44] <Tom_itx> no hotels, no food... all included
[02:12:47] <PetefromTn_> hehe I guess we won't be traveling to NZ any time soon LOL
[02:13:19] <PetefromTn_> unless I luck the hell out and get my CNC lathe working and pickup some kinda kickass job real quick LOL
[02:13:54] <trentster> PetefromTn_: how much did you expect it to cost? that sounds pretty cheap to me
[02:14:22] <PetefromTn_> It does to me as I said
[02:14:23] <Tom_itx> pretty good for 2 weeks
[02:14:37] <PetefromTn_> but it is out of the question right now LOL
[02:14:41] <trentster> its $100 a day fully inclusive
[02:14:46] <PetefromTn_> hey I can dream right LOL
[02:14:54] <Tom_itx> put it on your bucket list
[02:15:30] <PetefromTn_> just driving down to Orlando, staying with family, and going to Disney for a week we spent almost 2 grand LOL
[02:16:02] <Tom_itx> that's cause you went to disney
[02:16:39] <PetefromTn_> so yeah flying halfway around the world and seeing one of the most beautiful countries on earth for that money is reasonable
[02:16:46] <Tom_itx> i've managed to dodge that bullet so far
[02:17:00] <PetefromTn_> what bullet is that?
[02:17:06] <Tom_itx> disney
[02:17:13] <PetefromTn_> Oh hell I love disney
[02:17:28] <PetefromTn_> when I lived in Florida we went at least twice a year or more.
[02:17:31] <Tom_itx> i'd much rather see natural things than some built up swampland
[02:18:10] <Tom_itx> but my kids are past that age too
[02:18:27] <jdh> I used to drop my wife/kids off at disney and then I'd go diving
[02:19:02] <Tom_itx> hah
[02:20:27] <PetefromTn_> I like the great restaurants and all the rides. WHen you have small kids you really can't NOT take them to disney it is just UN-AMERICAN LOL
[02:20:31] <Tom_itx> i should sleep i suppose.. gotta get up at 3 and head to the airport
[02:20:43] <jdh> for a cruise?
[02:20:47] <Tom_itx> no
[02:20:57] <Tom_itx> she's gonna go see her sister

[08:02:20] <trentster> Anyone here ever made a lowish powered DIY laser CNC machine - I am looking to make something primarily for etching acrylic.
[08:02:30] <trentster> Any thoughts on DIY build vs buy ready made?
[08:04:21] <MrSunshine> more fun to dyi ? =)
[08:04:34] <MrSunshine> but requires a skillset =)
[08:04:51] <archivist> learn while doing
[08:04:57] <trentster> sure - but which is more cost effective and will you land up with a better spec machine going that route
[08:05:18] <archivist> yes/no/impossible to say
[08:05:48] <MrSunshine> i do not regret building my router myself, learned alot of metalworking etc while doing it =)
[08:05:52] <trentster> What Watt Laser would I need for etching and acrylic cutting( multiple passes ok)
[08:06:09] <MrSunshine> and how materials behave under stress ... damn steel to be soft
[08:06:29] <archivist> the wattage depends on colour of material
[08:06:50] <Jymmm> no comment
[08:07:14] <trentster> any recommendations from a laser perspective - could I get away with non CO2 laser for this stuff. I really don't sallivate over the idea of aligning tube optics
[08:07:35] <trentster> archivist: assume clear acrylics
[08:08:05] <archivist> I dont have one, I would have to google
[08:09:45] <Jymmm> archivist: Need a strip/pipe heater? http://www.ebay.com/itm/White-Exhaust-Thermal-Warp-Tape-Stainless-Electric-Heating-Band-Ties-1M-SP21/131586316364
[08:10:28] <archivist> no
[08:10:32] <archivist> I need a car
[08:10:42] <Jymmm> mill one?
[08:10:43] <trentster> This is what I have spare lying around the office: lots of 10 series t slot extrusion, quite a lot of 12mm wide linear rail with mini linear guideway/blocks and a couple of nema 17's and cogs and belts
[08:11:08] <Jymmm> archivist: OH I know.... 3d print one =)
[08:11:14] <trentster> which to me is pretty far along the way towards a buildable laser machine.
[08:13:22] <Jymmm> archivist: what happened to your car?
[08:14:32] <trentster> Also you guys in the US - what are the current 3 biggest "urban workshop" business in the US. The urban workshop website says "Urban Workshop is the 3rd largest DIY workshop and makerspace in North America" any clue what the other 2 are?
[08:14:55] <archivist> Jymmm, it dies a year ago, been borrowing a van
[08:15:00] <archivist> died
[08:15:18] <Jymmm> archivist: OH that sucks.
[08:16:31] <Jymmm> archivist: I bought 20yo civic off craigslist for $1400, looked ugly but actually ran great.
[08:17:09] <Jymmm> Really just needed some TLC.
[08:17:39] <trentster> If anyone reads my question in the channel and knows the answer please ping me - much appreciated
[08:17:41] <archivist> when working about 1 day a week that is expensive
[08:18:46] <Jymmm> ah, yeah
[08:20:10] <archivist> trentster, the problem is different mixes and colours will heat/melt in different ways with a laser
[08:20:40] <Jymmm> This is kinda funny, kinda sad... http://www.ebay.com/itm/Self-Locking-Contact-Clear-Cover-Red-Emergency-Stop-Push-Button-Switch-/321346624818

[10:41:52] <XXCoder> fucked up bad at work
[10:42:15] <XXCoder> one machine dont change to first tool when ran, and I forgot to change tools to that one before running
[10:42:25] <XXCoder> destroyed a cat50 chuck :(
[10:42:34] <XXCoder> could be worse, but not much worse

[10:49:21] <enleth> XXCoder: what about the spindle?
[10:49:31] <XXCoder> its fine, like i said it could be worse
[10:49:43] <XXCoder> chuck went down to side of fixture, and went up against it
[10:49:54] <XXCoder> it tightened way past its specs and cracked
[10:50:03] <XXCoder> 3 jaws smashed together
[10:50:26] <XXCoder> fixture itself have massive gouge on it, and one support for part is bent
[10:50:48] <XXCoder> kurt jaws dont seem to be touched, but I definitely would have checked it over before reset
[10:51:06] <XXCoder> part that was on it was destroyed of course
[10:51:11] <enleth> tbh, while the next worst thing - spindle damage - would require substantially more bad luck, it would have been much worse
[10:51:32] <XXCoder> just glad it didnt smash into table

[11:04:40] <XXCoder> archivist: just hoped to never have tool crash
[11:04:40] <_methods> did you knowck the fixture out of whack?
[11:04:47] <XXCoder> _methods: it got pushed off
[11:04:53] <_methods> ouch
[11:04:56] <XXCoder> and jammed with chuck gouging it
[11:05:02] <_methods> if you run cnc machines you'll crash at some point
[11:05:06] <_methods> just learn from it
[11:05:10] <XXCoder> it was X axis error that stopped it
[11:05:10] <enleth> the tension in the adapter that got released when it finally gave in was enough to shift the whole mill out of position by a visible distance
[11:05:42] <XXCoder> _methods: thanks. hopefully i will surive the roast from boss
[11:05:43] <_methods> guy at work crashed a lathe so bad one time he cracked the turret

[11:05:47] <_methods> he got fired
[11:05:54] <XXCoder> I accept it as it was my own dumb fault

[11:06:19] <_methods> pick the machines you hate the most and master them
[11:06:22] <XXCoder> turret forgot what it is?
[11:06:44] <_methods> what?
[11:06:50] <XXCoder> _methods: yeah been running okuma often its mostly fine
[11:07:12] <XXCoder> I just hate the fact that it can't change tool at beginning of program
[11:07:13] <_methods> i always go for the machines no one else wants to run
[11:07:15] <XXCoder> no idea why
[11:07:27] <archivist> turrets are boring
[11:07:51] <XXCoder> enleth: whats turret?
[11:08:02] <_methods> it holds the tools in a lathe
[11:08:07] <XXCoder> ouch
[11:08:10] <XXCoder> expensive
[11:08:13] <_methods> umm yeah
[11:08:45] <XXCoder> I remember reading about one guy who hit lathe so hard the umm chuck? broke off when it was spinning very fast
[11:08:53] <XXCoder> it spun around inside machine. machine was totaled
[11:08:59] <XXCoder> it was 6 months old
[11:09:07] <_methods> yeah lathes can get ugly real fast
[11:09:16] <XXCoder> I'm scared of lathes frankly
[11:09:24] <XXCoder> I only ran lathe 5 times so far
[11:10:24] <XXCoder> anyway
[11:10:32] <XXCoder> lets see what happens tomorrow.
[11:10:34] <_methods> you should be scared of all of them
[11:10:45] <enleth> there was an yt video of a substantially sized lathe with the saddle ripped from the ways in a crash
[11:11:09] <_methods> yeah that's a good crash lol
[11:12:01] <enleth> the toolholder was missing completely, I guess whoever was recording that did not think of looking at the ceiling yet
[11:12:17] <enleth> I'd bet it was lodged there
[11:12:58] <archivist> throwing parts for yards on a crash
[11:13:45] <_methods> man i was setting up a new part on a lathe one time and it was about 6" diameter and about 8" long 304ss part
[11:13:47] <archivist> was a long walk to get a bit at a factory I used to work at :)
[11:14:09] <_methods> the guy who was on the machine before me had turned the chuck pressure way down because he was doing a thin wall part
[11:14:14] <_methods> and i didn't catch that
[11:14:20] <archivist> wrecked the saw blade
[11:14:33] <_methods> i spun that part up that it slung that blank out of the chuck
[11:14:50] <XXCoder> ouch
[11:14:50] <_methods> knocked all my tools off the turret and smashed the hell out of the inside of the lathe
[11:14:58] <_methods> i shit my pants
[11:15:06] -!- justanotheruser has quit [Ping timeout: 240 seconds]
[11:15:18] <_methods> put a huge dent in the door
[11:15:28] <XXCoder> was it repaired or?
[11:15:44] <_methods> well luckily all it did was mess up all my tools and cosmetic damage to the door
[11:15:56] <_methods> the turret was still true thank god
[11:16:09] <_methods> so i just lost like 2 hours resetting tools
[11:16:33] <enleth> _methods: I'd label the dent on the door "this is why you check chuck pressure"

[11:18:43] <malcom2073> parts coming loose is scary
[11:18:51] <_methods> it's why i always close the door too lol
[11:18:51] <XXCoder> yeah i would be whole pounds lighter after that
[11:19:02] <_methods> i've always been good about that
[11:19:02] <malcom2073> Guy at my work had a vacume hold down fail on a mill, took out half his face

[11:19:21] <malcom2073> it went through it
[11:19:23] <_methods> saw i guy get knocked out runnin with door open
[11:19:27] <_methods> oh ouch
[11:19:36] <malcom2073> It was only 1/4" lexan
[11:19:47] <XXCoder> ouch
[11:19:56] <_methods> musta been a haas lol
[11:20:08] <malcom2073> It was some large VMC, the 20hp motor variety
[11:20:24] <_methods> cnc machines are dangerous that's for sure
[11:20:32] <enleth> malcom2073: started spinning on the drill and got loose at high rpm I guess?
[11:20:44] <XXCoder> _methods: yeah
[11:20:48] <malcom2073> enleth: that's what we assume happened yeah
[11:21:03] <XXCoder> malcom2073: at training job, we had "air blackouts"
[11:21:08] -!- justanotheruser [justanotheruser!~Justan@unaffiliated/justanotheruser] has joined #linuxcnc
[11:21:10] <XXCoder> guy was using vacuum hold
[11:21:27] <XXCoder> it sure flew good, but luckly he used portable wall to block
[11:23:10] <XXCoder> manual mill not cnc though
[11:23:22] <XXCoder> and they later upgraded from single big air tank to 4
[11:24:06] <enleth> are there any viable failsafe approaches for a vacuum table?
[11:24:50] <archivist> remove the vacuum table and use bolts
[11:24:57] <XXCoder> cant
[11:25:05] <XXCoder> its facemilling very thin part
[11:25:13] <XXCoder> and it covers entire thing in a shot
[11:26:05] <enleth> maybe glue it and dissolve/melt the glue later?
[11:26:31] <XXCoder> if I recall, strip of metal, 3 mm thick, mill off around half mm off both sides
[11:26:44] <XXCoder> enleth: could be a solution but not solution they used
[11:27:02] <enleth> the clickspring guy does that, seems to be effective and safe on big flat parts
[11:27:51] <_methods> yeah they make uv cure setups for stuff like that
[11:27:53] <enleth> the force needed to shear off the glue sideways is enormous
[11:27:59] <_methods> much safer than vacuum
[11:28:06] <_methods> more expensive though
[11:28:20] <XXCoder> do glue just melt off part too?
[11:28:30] <XXCoder> part required to be very smooth
[11:28:32] <_methods> the uv cures it and releases
[11:28:45] <_methods> you put uv lights in your fixture plate
[11:29:21] <_methods> https://www.youtube.com/watch?v=f5eSam7o8gk
[11:29:23] <_methods> like that
[11:29:55] <enleth> XXCoder: and if you want it cheaper, you glue the part to a ribbed plate with cyanoacrylate glue, then heat the plate to soften the glue
[11:31:21] <archivist> shellac as a hot melt glue too
[11:31:29] <XXCoder> cool. company work at now dont make that type parts though so its fine lol
[11:32:04] <_methods> oh snap
[11:32:25] <_methods> that freddy gray guy that died in baltimore had spine surgery the month before he died
[11:33:26] <_methods> guess that might make the prosecutions case a little tougher
[11:34:19] <XXCoder> why?
[11:34:34] <_methods> because he had a preexisting condition
[11:35:02] <XXCoder> it was a health insurance lawsuit or?
[11:35:18] <_methods> no
[11:35:39] <_methods> you remember there were like riots in baltimore a while ago
[11:36:04] <_methods> because the police "murdered" this guy freddie gray
[11:37:27] <XXCoder> from what i read, he got neck injury, and he didnt live because he didnt get any care
[11:39:27] <XXCoder> his neck was seriously broken so he couldnt breathe
[11:39:33] <XXCoder> so he suffered brain death
[11:40:57] <_methods> well like most stories, they're starting to find that there is more to it
[11:41:36] <XXCoder> earlier news just say back problems, while some other say he also has broken neck
[11:41:40] <_methods> or at least more of the truth is starting to leak out
[11:42:02] <XXCoder> being a cop does noit mean he or she is automically in right
[11:42:22] <XXCoder> theres no way to know what is truth so I'll leave em to figure it out,.

[12:56:41] <MikkoP> Hey, what about calculating maximum lifting weight for stepper motors? Wikipedia has something https://en.wikipedia.org/wiki/Ball_screw#Equations
[12:57:11] <jthornton> oh I remember now there are two hard drives in this computer lol
[12:58:01] <MikkoP> But with my 3 Nm motors and 5 mm pitch (assuming 90 % efficiency) it says almost 3400 Newtons...

[13:12:24] <enleth> MikkoP: 3Nm of what? holding torque?
[13:12:38] <MikkoP> enleth: yes
[13:13:03] <archivist> holding torque is not what they can move
[13:13:25] <MikkoP> archivist: No it's not but how do I calculate?
[13:13:29] <enleth> so assuming a ballscrew that can be backfed, you'd have to apply 3400N to force it to turn
[13:13:38] <jthornton> yea it is just how hard it will not move lol
[13:13:47] <archivist> if he got the maths right
[13:13:48] <enleth> sounds not completely unreasonable
[13:14:02] <enleth> but a little high
[13:14:16] <archivist> I am somewhat sceptical of that number

[13:22:55] <jthornton> cool calculator
[13:24:11] <MikkoP> archivist: I tried this earlier today but didn't understand it. I assume force is the amount that needs to be lifted. Let's say it's 300 N or 30 kg. I have NEMA 23 motors so 0.25 inch shaft diameter (or should this be ball screw diameter?). I'm not sure about thread density. My ball screws have 5 mm pitch. Friction coefficient I set to 0.2 to be on the safer side.
[13:24:36] <MikkoP> This outputs 29.2 Ncm raising torque and lowering -9.7.
[13:26:18] <archivist> would be interesting to actually measure a screw one day
[13:28:33] <archivist> it basically depends on the helix angle which is a function of pitch and diameter
[13:31:53] <MikkoP> Someone should do "CNC for newbies" or something
[13:32:25] <MikkoP> According to the Wikipedia page on helix angle I get 87 degrees for my screw. What?!

[16:19:19] <CaptHindsight> ZORO and Amamzon also tend to have some in stock

[16:21:24] <Jymmm> CaptHindsight: That's free (flyers)

[16:23:22] <Jymmm> not everyone does
[16:23:33] <Erant> Oh, I know, I appreciate it.
[16:24:09] <CaptHindsight> save money by buying elsewhere and something more reliable

[20:56:34] <XXCoder> love how much it looks like clay.
[20:57:25] <ReadError> any creative solutions to adding encoders to single shaft motors?
[20:57:38] <ReadError> I snagged a few of the blowout BLDC servos
[20:59:30] <XXCoder> ReadError: between the motor and screw?
[20:59:41] <XXCoder> it'd have to use two couplers or something
[20:59:57] <ReadError> yea, was wondering if they had something to fit over the existing shaft
[21:00:02] <ReadError> like a coupler+enclosure
[21:00:03] <PetefromTn_> most people just drill and tap the end shaft in the lathe
[21:00:06] <ReadError> then mount that to something
[21:00:54] <XXCoder> some machines has rotating nut at other end, could use for encoder? but then backlash probably will affect it
[21:00:57] <ReadError> I think if I switch my project over to them ill just buy the double sided ones and proper encoders
[21:01:19] <ReadError> but for 29$ I just grabbed some to play with VESC
[21:02:59] <CaptHindsight> ReadError: what is the motor driving? A shaft with a coupling? Is there room on the other end of the shaft for an encoder?
[21:03:15] <ReadError> CaptHindsight well I want to use them on my PNP possibly
[21:03:25] <ReadError> which will need a pulley for a belt

[22:53:37] <Erant> That's largely what I'd be aiming for.
[22:55:15] <JT-Shop> I mill up to about RC58 on my mill with carbide tooling
[22:55:42] <SpeedEvil> Ah
[22:55:53] <SpeedEvil> You can indeed harden HSS - but holy shit
[22:55:53] <JT-Shop> if you take the right amount of chip out the material never even gets warm with no coolant
[22:56:03] <JT-Shop> coolant = bad for carbide
[22:56:11] <SpeedEvil> '
[22:56:11] <SpeedEvil> Pre heat the steel in two steps; 450-500°C then 850-900°C. Then continue heating to the final hardening temperature of 1200-1250°C and ensure that the component is heated through. Care must be taken not to allow the component to remain too long at the hardening temperature. Quench in warm oil or brine. If quenching in brine allow the tools to equalize, then complete the quench in air. If quenching in oil remove the component from the oil at
[22:56:11] <SpeedEvil> about 500°C and then air cool. M2 high speed steel is also suitable for vacuum hardening.

[22:58:30] <andypugh> You can go old-school and use something like O1 tool steel. Easy to harden, worked perfectly well for centuries.
[22:58:47] <SpeedEvil> yeah
[22:59:01] <Erant> SpeedEvil: That's a great video.
[22:59:10] <SpeedEvil> It is.
[22:59:17] <SpeedEvil> Plus he uses comparatively modest tooling.
[22:59:19] <SpeedEvil> Which is nice

[22:59:45] <Erant> Totally. That's given me the confidence that I could totally do this at home with what I have.
[23:00:06] <SpeedEvil> What the hell is teh point of advertising that, if you're going to stick up a whole website, and 'call' for every single item.
[23:00:10] <Erant> Really time to get that lathe. :P
[23:00:49] <andypugh> SpeedEvil: You can buy silver steel (a lot like O1) easily. From Cromwell tools for a start, and on a saturday morning.

[23:36:31] <thesaint> hi, anybody out there?
[23:38:32] <JT-Shop> nope
[23:39:57] <thesaint> hi, i am trying to learn linuxcnc gcode for lathe. do you know where i can find a good resource? scripts of basic operations maybe? thanks..
[23:40:13] <Tom_itx> gcode is pretty much gcode

[23:43:03] <thesaint> Tom - do you have a cnc lathe?
[23:43:11] <Tom_itx> then there's always this one: http://gnipsel.com/linuxcnc/g-code/
[23:43:24] <thesaint> gnipsel is the best i found so far..
[23:43:29] <Tom_itx> nope but i've programmed / run one
[23:43:40] <Tom_itx> yeah he's quite a character i hear
[23:43:48] <thesaint> well those links apart from gnipsel are not usefull.
[23:44:23] <thesaint> i am really looking for scripts i can play with to get an idea what is going on.
[23:44:24] <Tom_itx> the author is hiding here somewhere
[23:44:39] <thesaint> his was good.
[23:45:07] <thesaint> and i will work from there if that is all i can find.
[23:45:40] <thesaint> would be good if i could chat with someone with a cnc lathe and find out how they actually use it to make parts...
[23:46:40] <Tom_itx> just ask, there are plenty here
[23:47:46] <thesaint> does anyone have a script i can have a look at that turns a rod to a certain diameter and length?
[23:48:16] <thesaint> what is the workflow for making parts with a cnc lathe?
[23:48:39] <thesaint> are there any helper scripts for doing this stuff?
[23:48:48] <thesaint> do i have to make them all myself?

[23:50:40] <JT-Shop> ngcgui handles 95% of the ops on my CHNC lathe
[23:51:08] <JT-Shop> btw, I'm gnipsel
[23:51:16] <thesaint> jt-shop - you are gnipsel?
[23:51:24] <JT-Shop> aye
[23:51:42] <thesaint> cool, have been looking at your scripts and learning - thanks!
[23:51:48] <JT-Shop> I'm also jthornton
[23:52:16] <JT-Shop> your welcome, glad someone gets a benefit from them
[23:53:02] <thesaint> how do i setup the ngcgui ? that is what i am looking for to get started. yes i did benefit, only crashed my machine twice :-)
[23:53:12] <JT-Shop> Tom_itx: 12 pieces of siding and 6 pieces of gable to go
[23:53:18] <thesaint> just small crashes.. lol
[23:53:36] <Tom_itx> you might make it by winter
