[04:37:27] <_abc_> Hello
[04:37:34] <_abc_> Has anyone got a CH353L based PCI multi io card? They are very common. 2*serial + 1 parallel. Unable to set BREAK condition under linux... has anyone seen this?
[04:37:47] <_abc_> I confirmed with 2 different programs that I can't set BREAK at all on this card.
[04:37:55] <_abc_> On either serial port.
[04:37:59] <_abc_> Otherwise they work fine
[04:48:30] <_abc_> 12:13 < _abc_> Has anyone got a CH353L based PCI multi io card? They are very common. 2*serial + 1 parallel. Unable to set BREAK condition under linux... has anyone seen this?
[04:52:12] <XXCoder> okay
[05:35:56] <jthornton> never heard of a CH353L...
[05:39:01] <SpeedEvil> Basically dirty hydrogen I guess.
[05:50:36] <XXCoder> any good? http://www.amazon.com/Autek-Titanium-Carbide-Engraving-J3-3001Tix10/dp/B00HC98K2C
[07:22:44] <Tom_itx> https://www.youtube.com/watch?v=kKv8AaHqsNY
[07:26:15] <skunkworks> pretty cool - seen that before
[07:26:34] <archivist> I was trying to count her fingers she had left
[07:26:39] <Tom_itx> hah
[07:27:12] <archivist> they needed a bigger female so it looked less hard to turn too
[07:28:35] <skunkworks> the matsurra has 3 unshielded bundles of wires going between the old control and the servo drives. Each bundle has 2 twisted pair - one for the tach and one for the analog input. Must have worked great.
[08:18:15] <R2E4> mornin all
[08:37:24] <jdh> searching for autocad drawings in floppies is painful
[08:38:24] <archivist> write a little cataloguing program to store the listing to database
[08:40:24] <jdh> > and grep are my db
[08:44:19] <archivist> slow way, think about the next time :)
[08:59:34] <JT-Shopp> damn hoe has a flat this morning
[09:03:53] <jdh> those damned hoes
[09:05:01] <JT-Shopp> I knew something was up yesterday when it only had 9 psig
[09:06:11] <jdh> fix-a-flat. 20 or 30 cans?
[09:07:37] <JT-Shopp> lol, it takes a long time to fill a 16.9-24 even with shop air it took 15 minutes
[09:07:40] <jdh> archivist: I'm just copying them all. the cad guy can deal with updating the vault
[09:08:16] <jdh> I just meant enough sealant to coat the tire
[09:09:38] <archivist> jdh, floppies dont have the best lifetime so a digital copy is a good idea
[09:10:17] <JT-Shopp> you don't use fix a flat on a backhoe
[09:10:34] <jdh> we have a nicely backed up autodesk vault. dunno why these aren't in there
[09:11:50] <jdh> bet new ones are pricey
[09:12:18] <JT-Shopp> tires yea about $500
[09:12:23] <jdh> you don't fix anything with fix a flat, you just make things worse
[09:32:37] <jdh> ended up with one bad flip
[09:32:42] <jdh> floppy
[09:34:53] <JT-Shopp> damn usps.com is down
[09:37:02] <jdh> thanks obama
[09:42:50] <JT-Shopp> yea right in the middle of shipping a package to Hampshire
[09:46:47] <jdh> you could go wait in line at the post office until they close for lunch
[10:34:56] <robin_sz> so, the "xset s dpms" thing seems to have made the screen stay on, hurrah!
[10:35:20] <robin_sz> will this be a permanent fix, or will I have to do somethign next time I reboot?
[10:44:51] <jdh> every time
[10:47:38] <jdh> you can put it in the startup config though
[10:48:26] <jdh> //etc/X11/xorg.conf.d/ maybe?
[10:54:17] <jdh> or maybe xinitrc
[10:56:18] <CaptHindsight> _methods: http://www.theverge.com/2016/4/13/11424924/coolest-cooler-kickstarter-disaster-delays looked legit to me, I ordered 4 :) (not really)
[11:06:29] <CaptHindsight> http://www.amazon.com/dp/B016VXVLFC?ref=spks_0_0_2290285542&qid=1447888279&pf_rd_p=2290285542&pf_rd_m=ATVPDKIKX0DER&pf_rd_t=301&pf_rd_s=desktop-auto-sparkle&pf_rd_r=0Q7W2P3BT65PP7MWDFRQ&pf_rd_i=coolest+cooler#Ask
[11:12:26] <MrSunshine> yey done some metal scraping for a friend =)
[11:12:43] <MrSunshine> his compound on the lathe will never be the same again :P
[11:18:38] <Loetmichel2> meh, is that undecided gantry mill guy STILL not satisfied?
[11:18:44] <Loetmichel2> getting a bit boring lately...
[11:18:57] <Loetmichel2> ( looked at the scrollback about 8 hours ago)
[11:19:32] <Loetmichel2> s/8(18
[11:19:36] <Loetmichel2> s/8/18
[11:19:43] <CaptHindsight> Loetmichel2: didn't he change nicks yet again and announce what he got yesterday
[11:20:08] <djdelorie> that's what drills are for - getting a bit boring :-)
[11:20:26] <gregcnc> I don't think he actually bought anything,
[11:21:01] <CaptHindsight> not worth the time
[11:22:16] <CaptHindsight> there are coolers to be designed and built
[11:22:38] <t12> did you figure out your plastic molding thing
[11:23:24] <CaptHindsight> “If they gave out the Nobel Prize for coolers, this would win” – Matt Lauer, Today Show
[11:23:55] <gregcnc> LOL
[11:24:21] <gregcnc> carbide dovetail cutters cost too much
[11:24:30] <CaptHindsight> t12: the world has more pressing needs
[11:24:48] <t12> rimshot
[11:33:12] <Encapsulation> nothing yet, getting much closer though
[11:33:30] <Encapsulation> to respond to djdelorie gregcnc CaptHindsight and Loetmichel2
[11:33:40] <Encapsulation> I'll keep you posted with any progress
[11:36:10] <CaptHindsight> http://soundbible.com/grab.php?id=393&type=wav for anyone still wondering if he got anything
[11:39:04] <Loetmichel2> gregcnc: really?
[11:39:10] <Loetmichel2> do you mean the wooden ones?
[11:39:23] <Loetmichel2> they are dirt cheap in my opinion
[11:39:30] <Loetmichel2> (the router bits)
[11:39:52] <gregcnc> solid carbide for milling
[11:40:55] <Loetmichel2> CaptHindsight: that was a PRETTY low quality barking puppy.. an the aliasing sound even could be out of a 56ties SF movie ;)
[11:40:58] <Loetmichel2> 60ties
[11:43:01] <CaptHindsight> I'll search for a better quality clip for you when I have time some time in 2019
[11:43:21] <CaptHindsight> remind me if i forget :)
[11:43:50] <Loetmichel2> will do. IF i remember (unlikely as it is) ;_)
[11:44:24] <Loetmichel2> what i wanted to say: the aliasing sounds in the BG were more interesting than the forground barking dog ;)
[12:16:03] <maxcnc> hi
[12:16:07] <CaptHindsight> t12: for small patterns up the size of a chocolate coin (2" dia), CNC in a NSF plastic...
[12:16:12] <maxcnc> a wonderfull day in germany
[12:17:25] <CaptHindsight> t12: for larger patterns, SLA with a NSF thin barrier film placed on it where it comes into food contact
[12:18:34] <CaptHindsight> e.g. few micron polyolefin film vacuum formed and bonded to the SLA pattern
[12:19:36] <CaptHindsight> you could use a SLA resin that is food grade but the components are more expensive and you still have to spend time cleaning it
[12:48:01] <R2E4_> Can I connect an led to an input on a 7i77 for a touch off probe so when the input gets a closed contact the led lites?
[12:48:57] <R2E4_> As a tool setter for example or a touchoff.
[12:50:01] <pcw_home> yes but it may be a bit dim (inputs are 22K Ohms to ground)
[12:50:41] <djdelorie> unless the contact itself is driving the led?
[12:52:52] <maxcnc> R2E4_: why not a output and connect it via hal
[12:53:39] <djdelorie> you mean... use an entire PC to make it so that closing a switch turns on a light?
[12:54:24] <CaptHindsight> with a smartphone you could monitor it from the beach
[12:55:19] <djdelorie> heh. I *actually* need a way to monitor a switch from a smartphone, so my wife knows if the garage door is already open when she comes home.
[12:56:01] <CaptHindsight> are there any websites with a Rube Goldberg setup for sending messages through the most torturous courses?
[12:56:25] <CaptHindsight> djdelorie: blind driver?
[12:56:38] <maxcnc> im off Gn8
[12:56:39] <djdelorie> blind corner - you can't see the doors until you're nearly there
[12:57:13] <djdelorie> the range of the button is WAY bigger than the range of line-of-sight
[12:58:28] <JT-Shopp> is usps.com down for you guys?
[12:58:29] <CaptHindsight> another solution could be a signal that transmits braking to the cars ABS if the door is closed
[12:58:57] <CaptHindsight> JT-Shopp: slow buy works
[12:59:01] <CaptHindsight> buy/but
[12:59:20] <djdelorie> what I want is a way for her to push the "open door" button and have the door not close if it's already open
[12:59:22] <JT-Shopp> must be wildblue
[12:59:28] <JT-Shopp> thanks for checking
[12:59:36] <djdelorie> otherwise she just waits in the car outside the garage while the door opens
[12:59:40] <CaptHindsight> i use it near daily and i hate it
[13:00:30] <R2E4_> pcw_home, Would a energizing a relay and having one contact fire led and the other input into 7i77?
[13:00:44] <CaptHindsight> JT-Shopp: my favorite is having 10 labels in the cue and then the download speed for the pdf crawls and takes 12 minutes to print
[13:00:57] <JT-Shopp> finally back up here
[13:01:03] <gregcnc> would those new anti crash cars stop the car if the door was shut?
[13:01:08] <JT-Shopp> yea that would suck
[13:01:53] <R2E4_> machines are piling up: have a bridgeport to convert, a router 8020 frame and biesse rover 346 all with mesa 7i77's
[13:01:53] <CaptHindsight> JT-Shopp: happens every Saturday 1 hour before the post office closes
[13:02:10] <CaptHindsight> JT-Shopp: i think they do it just for fun
[13:02:33] <gregcnc> and hack peoples webcams to watch?
[13:03:13] <pcw_home> R2E4_: Is this for a probe? if so you need to be careful about contact current so you dont erode the contacts
[13:03:14] <CaptHindsight> gregcnc: nah, it's more good luck not waiting either in line or on the web
[13:04:19] <R2E4_> Can do solid state relay
[13:04:27] <CaptHindsight> now I have the idiots at the counter asking me if the packages have anything liquid or flammable inside after printing my own labels
[13:05:01] <CaptHindsight> yes, you can send liquids and flammables via USPS, they just have to be small enough and in the proper packaging
[13:05:36] <gregcnc> right it's complicated, but that should catch those who know nothing
[13:05:52] <gregcnc> but don't they know you yet or you don't go in person often enough?
[13:06:24] <CaptHindsight> or just nosy, petty tyrant etc
[13:06:56] <gregcnc> but maybe you're isis
[13:07:19] <gregcnc> you know the postoffice should watch for them
[13:07:25] <CaptHindsight> "isis not a bomb" label is right on the front of each box
[13:07:40] <gregcnc> nice
[13:08:15] <pcw_home> most probes are NC so the LED would have to go across the probe contacts
[13:08:16] <gregcnc> i haven't been in there to deal with them since they made international labels
[13:09:09] <CaptHindsight> gregcnc: they just did away with the dumb 4 copies in those plastic covers
[13:09:21] <CaptHindsight> now it's just one label you stick down
[13:09:38] <gregcnc> yeah ebay had it a long time ago
[13:10:12] <CaptHindsight> "Click-n-pray" labels at USPS.com
[13:10:20] <gregcnc> or paypal multi ship I stopped using the PO sight long ago
[13:10:23] <gregcnc> site
[13:11:41] <gregcnc> when they wouldn't let you print anything to a label printer, but ebay and paypal did
[13:11:54] <CaptHindsight> https://ship.paypal.com/powership/powership.html go directly there and it goes nuts
[13:13:53] <gregcnc> time for leftover quesadillas
[13:53:07] <CaptHindsight> gregcnc: if they get old enough you can use them for test blanks on the mill
[13:53:21] <gregcnc> too late
[14:16:23] <Crom> sheeeshz, you want a laugh? check out adafruit's 'othermill' $2200 for a piece of plastic "cnc mill"
[14:17:40] <Encapsulation> considered it, didnt look like a very good deal at all
[14:29:18] <CaptHindsight> sold out https://www.adafruit.com/products/2323
[14:29:23] <miss0r> goodevening
[14:29:33] <Deejay> hi there
[14:32:21] <Encapsulation> I saw a vid of it milling pcb, looked ok
[14:32:25] <Encapsulation> but its tiny and doesnt look rugged
[14:32:27] <Encapsulation> and the price is absurd
[14:36:31] <miss0r> hmm. I have a strange leaver on the side of the ram on my maho 500c mill. it says "1" and "0" and "only change when spindle not running". I wonder what it is - I can't seem to find it in the manual :/
[14:40:01] <Encapsulation> easiest way to find out is probably to change it with spindle running
[14:40:04] <BeachBumPete> pull it and see what happens ;)
[14:40:13] <Encapsulation> I'm jk ofc, don't do that xD
[14:40:23] <miss0r> Encapsulation, no shit :)
[14:41:00] <miss0r> BeachBumPete, I can feel it engaging the spindle somehow.. like a gear being moved into another gear... i'm left none the wiser. doesn't seem to affect the spindle rpm thou
[14:42:18] <BeachBumPete> could it be a low speed jackshaft?
[14:43:26] <miss0r> perhaps. I will remove the cover and see what is behind it
[14:44:27] <BeachBumPete> If its is obviously mechanical engagement I would turn off the spindle and grab the spindle by hand and try to engage it and see how it affects the difficulty in turning it by hand that should tell you something about what it does..
[14:46:30] <miss0r> indeed. cover is off... and it continues into the gearbox...
[14:46:45] <miss0r> not taking the gearbox apart for this. will try what you said about feeling the spindle
[14:50:28] <miss0r> annoying. I can't feel a change on the spindle when the knob is turned.
[14:50:37] <miss0r> All I can feel is a gear engaging another
[14:51:45] <BeachBumPete> Hmm I am not familiar with that machine at all so I am unfortunately of little help.
[14:52:10] <miss0r> hehe no problem dude. I'm just thinking out loud from time to time...
[14:54:57] <djdelorie> my mill has a power take-off for the quill auto-feed that's labelled like that, "in/out, stop before changing"
[14:56:06] <miss0r> This is a CNC mill, so I think that is out of the question
[14:56:14] <miss0r> but I can't say for sure
[14:58:04] <BeachBumPete> is it a little black round knob?
[14:59:04] <miss0r> http://www.akkstroje.cz/getfile/images-a/100465-1/frezky-cnc-mh-500c-100465-1.jpg the little black knob on the side of the ram there
[14:59:09] <miss0r> (random google picture)
[14:59:44] <BeachBumPete> http://www.extech-de.com/sites/default/files/files/angebote/maho_mh_500c_5_20140516_1385465015.jpg
[15:00:00] <miss0r> thats the one
[15:03:36] <miss0r> I just browsed through the machine manual, I couldn't find a single picture of it :)
[15:19:25] <miss0r> this is starting to piss me off :)
[15:21:55] <enleth> a friend is relocating back to the EU from CA in a few months, I guess I can start buying a shitload of used QC30 tooling and have it sent to him so that the moving company will just haul one more box of stuff on top of everything else for no additional cost
[15:25:12] <miss0r> found it! it is for activating the horisontal taper.
[15:33:40] <jdh> of course
[15:33:59] <CaptHindsight> ok who is throwing this years CNC Fest?
[15:35:12] <gregcnc> I might try ArnFest this year
[15:35:34] <BeachBumPete> I would but there is only one problem.... I am homeless :)
[15:36:02] <CaptHindsight> it could be outdoors
[15:36:27] <jdh> local walmart parking lot
[15:36:33] <CaptHindsight> CNC-B, CNC at the Beach
[15:37:05] <BeachBumPete> Hey that's not a bad idea.... CNC Fest/Beach Fest/BYOB/we catch dinner!!
[15:37:21] <XXCoder> Steal a large cargo ship, make it into cnc fest with machines
[15:37:29] <CaptHindsight> you can do it all over smartphones now anyway
[15:37:55] <CaptHindsight> http://arnfest.com/?page_id=89
[15:38:23] <CaptHindsight> "Subject to change due to any arising condition – weather, timing, availability of personnel and equipment, slothfulness, indifference, romantic entanglements, acts of war"
[15:39:40] <BeachBumPete> that should be my standard disclaimer ;)
[15:39:47] <CaptHindsight> gregcnc: never even heard of it and it's in my backyard
[15:40:01] <gregcnc> me neither, until last year
[15:40:05] <gregcnc> after it happened
[15:42:22] <CaptHindsight> gregcnc: the amount of woodworking and simple power tools make me wonder
[15:42:38] <CaptHindsight> vintage tool fest or old tool swap meet?
[15:42:49] <gregcnc> sounds like both
[15:42:58] <gregcnc> nothing like it around here
[15:43:10] <CaptHindsight> 118 people registered last year
[15:43:17] <CaptHindsight> from all over the country
[15:43:59] <gregcnc> I looked at some of the makerfaire dates but nothing looked intertesting
[15:44:11] <gregcnc> that is they don't really have any ifo
[15:44:35] <CaptHindsight> I gave up on those
[15:45:51] <CaptHindsight> the ArnFest is really at the Railway Museum
[15:46:43] <gregcnc> yeah i guess the trading is in the parking lot
[15:47:51] <gregcnc> I wonder if anyone has 6mm tubing around here
[15:48:06] <CaptHindsight> what material?
[15:48:19] <CaptHindsight> ID or OD
[15:48:22] <gregcnc> just for air OD
[15:48:29] <CaptHindsight> do make me beat the answers out of you!
[15:49:08] <CaptHindsight> menards is your best bet
[15:50:05] * Jymmm hands CaptHindsight the clue-by-four
[15:50:12] <CaptHindsight> they would probably salivate over archivist's collection
[15:51:08] <CaptHindsight> Jymmm: I'm already wearing my mind reading helmet and my sensitivity training pants
[15:52:02] <Jymmm> CaptHindsight: Well, take off your pants and do a little dance!
[15:53:22] <Deejay> these pictures in my head...
[15:54:30] <CaptHindsight> gregcnc: the ACE behind the Bestus Buy as well
[15:55:03] <gregcnc> menards doesn't list metric on the site, and ace only lists 10% of what they sell
[15:55:19] <unfy> first cut: http://i.imgur.com/8jbYVxl.png 2x4's, drawer slides, 5/16 all thread, t-nuts, nema 17's, some angle aluminum, a trim router
[15:57:18] <CaptHindsight> gregcnc: maybe 1/4"od trimmed down to 0.236"
[15:57:58] <XXCoder> unfy: I see some issues I think
[15:58:01] <gregcnc> I bet I could snake it through the spindle and do a decent job
[15:58:24] <XXCoder> few X motions where there should not be so some lines is little bumpy
[15:58:47] <XXCoder> could be just burrs though heh
[16:00:21] <unfy> xxcoder: the issues are gonna be 2 things.
[16:00:35] <gregcnc> pffft 1/4 fits 6mm
[16:00:42] <unfy> a) backlash was something i gave zero concern about
[16:01:21] <unfy> b) i'm using these kinds of things for motor <> leadscrew coupling http://ecx.images-amazon.com/images/I/41d5riYQBWL._SX342_.jpg
[16:02:15] <XXCoder> anti-backlash couplers
[16:03:46] <Connor> I would try that with some MDF.. Plywood is going to have bad tear-out.
[16:08:41] <XXCoder> or use push down endmills
[16:08:51] <XXCoder> forgot proper name, but it pushes chips down
[16:09:02] <Connor> down-spiral
[16:10:09] <Connor> Yea, MDF, Super High end plywood, and/or down-spiral bit.
[16:10:37] <XXCoder> I suppose can use lower feed rate, will wear tools little faster but less tear out
[16:12:21] <unfy> but, the leadscrew itself isn't held captive - so it can push/pull against the coupler.
[16:12:38] <Connor> unfy: You don't have bearings ?
[16:12:52] <Connor> That's a whole other issue..
[16:12:58] <XXCoder> yeah
[16:13:28] <Connor> You need to have at least one side supported with AC bearings.
[16:14:09] <Connor> you can do the far end and let the coupler and stepper support the other end.. I've seen that before..
[16:16:27] <CaptHindsight> Connor: don't tell the Chinese router makers :)
[16:16:54] <Connor> CaptHindsight: That's what I've seen on some of those Chinese routers..
[16:17:29] <Connor> the let the free float end be the side with the flex coupler and stepper, and use the AC bearings on the other end.
[16:17:52] <Connor> On mine, I did AC bearings on drive side, and a single floating bearing on the floating side.
[16:29:21] <Deejay> gn8
[16:30:14] <unfy> there's a block on the opposide side. i couldn't come up with a simple way to mount skateboard bearing, so it's a T nut pushed into some wood that's been drilled out to not have threads.
[16:30:17] <unfy> it chatters a bit :D
[16:30:34] <unfy> 'nite dj
[16:31:28] <unfy> sorry for delays -- busy here at work etc
[16:44:32] <JT-Shop> $158 to get the hoe flat fixed
[16:45:00] <djdelorie> there's a dirty joke in there somewhere...
[16:45:37] <jdh> it's laying there
[16:46:39] <jdh> like JT's worn out hoe
[16:47:27] <djdelorie> at least his hoe is all curvy again :-)
[16:50:11] <unfy> anyway, if i can think of a simple way to keep the leadscrew captive along it's long axis, that will solve a lot of the problems. backlash has a few simple fixes that i'll worry about later.
[16:52:35] <malcom2073> unfy: Thrust bearings
[16:53:34] <jdh> I got a grizzly flyer the other day. near the back, they were selling handcuffs, leg irons, et
[16:53:36] <unfy> so just push it against the coupler ?
[16:54:12] <unfy> that is, thrust bearing on the far end...
[16:55:56] <malcom2073> unfy: Not against the coupler, against the bearing block
[16:55:58] <malcom2073> the coupler should float free
[16:57:06] <unfy> [M] -[c]---------------[t] motor, coupler, thrust bearing ?
[16:57:16] <unfy> ascii art ftw
[16:57:48] <malcom2073> [M]-[C]-[T]-------[T]
[16:58:13] <unfy> and nuts to hold the lead screw against the bearings ?
[16:58:25] <unfy> well, captive to
[16:58:28] <malcom2073> Yep, probably also need axial bearings
[16:59:11] <malcom2073> Could do it from one end if your screw has ridges or this
[16:59:14] <malcom2073> http://i157.photobucket.com/albums/t63/BungalowFilms/CNC/2.jpg
[16:59:26] <malcom2073> With another clamp instead of the coupler holding the second side
[16:59:43] <malcom2073> That's just clamping though, preloading would be better
[17:03:14] <unfy> i.... think i can easily adapt some thrust bearings, and nuts into things. there's a point at which it's a "stop, build new / better machine" though heh
[17:03:22] <malcom2073> heh
[17:04:08] <unfy> the whole point of this build was to learn, get feet wet, etc. so investing too much equipment into existing build is beyond the scope of the machine
[17:04:21] <MrSunshine> http://s24.postimg.org/iq3s054vp/20160414_150138.jpg skill is improving i think =)
[17:04:22] <malcom2073> heh
[17:04:25] <unfy> the thrust bearings are a mail order situation, but they're inexpensive and easy to adapt
[17:04:48] <andypugh> That’s a good plan. I learned valuable lessons from my first CNC conversion. Like don’t start with a cheap chinese combination mill/lathe. :-)
[17:05:00] <malcom2073> Hah yeah
[17:06:19] <unfy> the thrust bearings / nuts thing should indeed keep the lead screws captive. next up will be dealing with back lash however i want to etc (lots of options, whatever, don't care atm)
[17:09:13] <unfy> just ordered some cheap bearings.
[17:12:08] <unfy> and, 2x4's and drawer slides: http://i.imgur.com/HY7cDS4.jpg ... just to demonstrate how... hardware-store quality it is heh
[17:12:20] <malcom2073> Hah nice.
[17:12:27] <malcom2073> Yeah get some cheap bearings on the end of your screw, should help a bi
[17:12:30] <malcom2073> bit*
[17:12:43] <malcom2073> Or get axially solid couplers
[17:14:25] <andypugh> One drawback about using quality machines, you find yourself trying to echo the quality of the orignal builders. The last few evenings I have been filling, rubbbing down, painting, filling…. bits of lathe. Looking nice though: https://picasaweb.google.com/108164504656404380542/Holbrook#6273531630598303666
[17:15:13] <gregcnc> When will the concours judging be?
[17:15:27] <andypugh> Well, yeah, quite.
[17:15:38] <andypugh> It’s pointless.
[17:17:26] <andypugh> But they were quite a well-presented lathe when new: http://www.lathes.co.uk/holbrook-minor/
[17:18:06] <unfy> andyO lol
[17:18:28] <unfy> yeah, i have to keep reminding myself of "scope of this machine" along with "just build the damn thing"
[17:40:09] <toastydeath> andypugh, that's a badass toolroom lathe
[17:40:40] <toastydeath> with lathes especially I totally understand the beautification process - there's so much more character to lathes than mills
[17:44:17] <unfy> ^
[17:44:59] <unfy> malcom: i'll get you an update mid / early next week after thrust bearings arrive. although it might be the weekend after that etc (gotta build/attach the thing they'll squeeze against)
[17:45:59] <malcom2073> Cool, I'll be interested to see it
[17:52:22] <unfy> I'll have to get a complete parts list as well. i know that there are always folks wondering about building a cheap machine etc, but it's a lot of talk and no actual demonstrations etc.
[17:52:30] <unfy> or finding one off custom deals that make things cheap, etc.
[17:52:40] <unfy> there is /nothing/ special about this machine.
[17:53:14] <unfy> well, i did braze the angle aluminum together instead of using a prefab motor mount bracket, but whatever.
[18:07:57] <andypugh> toastydeath: Have you seen my shiny living-room lathe?
[18:08:09] <toastydeath> neg?
[18:08:24] <Lowridah> i need a lathe
[18:08:54] <Lowridah> i like how simple this approach is
[18:08:55] <Lowridah> https://www.youtube.com/watch?v=WXIy7EX2vCY
[18:08:57] <andypugh> toastydeath: https://picasaweb.google.com/108164504656404380542/Rivett#5978884791542655522
[18:09:12] <toastydeath> damn, nice
[18:09:23] <toastydeath> that's a great stand, too
[18:10:06] <malcom2073> Lowridah: I wonder how they compensate for backlash
[18:10:12] <malcom2073> Most lathes have a hell of a lot in the screw
[18:10:19] <malcom2073> They're only meant to be accurate in a single direction
[18:10:28] <malcom2073> Or rather, not meant to be accurate reverseing
[18:10:42] <andypugh> It’s prettty unusual for a lathe cut to change the direction of applied force
[18:11:06] <andypugh> So, you can write the G-code to make moves like you would for manual use.
[18:11:15] <malcom2073> You can write the gcode like such, true
[18:11:27] <malcom2073> but it's not unusual for it to move the cross slide both out and in in one operation
[18:11:36] <malcom2073> for a cnc
[18:12:22] <malcom2073> I think that's a pretty slick concept though for quickly adding cnc capability
[18:13:05] <andypugh> reversible and non-destructive too. Though blocks of wood is a bit rough.
[18:13:18] <malcom2073> Ah the comments address it
[18:13:36] <malcom2073> "i I always set depth in one direction. I overshoot material safe and set depth in the few areas that's needed."
[18:14:14] <malcom2073> If I had a hundred or so items I had to make that could be done that way, I could see myself doing such a thing in a weekend to avoid having to A: make the parts, and B: buy a full cnc lathe
[22:37:11] <unfy> i'm thinking blendercam hm
