01:06 AM nvz: well, I guess I'm gonna order a Dell Optiplex 780 SFF I can get it for about $50 w/ E7500 4GB 250GB I already have the USFF with E8400 4GB 320GB.. so.. I can take the RAM/CPU/HDD out of it and upgrade the SFF model, and another $9 will get me a dual-dp radeon hd 3470 for it
01:11 AM nvz: I'm also gonna order a digital tachometer and 4 digital inline DC Ammeters and another control board.. one with some relays on it
01:13 AM Wolf__: at some point I need to get back to messing with my dull optiplex boxes
01:13 AM Wolf__: too many projects lol
01:14 AM nvz: heh.. yeah well, I got this USFF here but no parport.. so I'm gonna order the SFF one and put the faster CPU out of the USFF in there and the extra 4GB ram.. the USFF maxes out at 4GB but the SFF has two extra slots
01:14 AM Wolf__: right now I’m trying to figure out how to design a led array, which I have no idea wtf I’m doing
01:15 AM nvz: heh.. yeah I wanna do that one of these days too..
01:15 AM nvz: leds have gotten very cheap
01:16 AM Deejay: moin
01:17 AM Wolf__: when I originally built my work truck, I put some atomic led replacement cab lights on it that also work as warning lights, not impressive, its kinda crappy boards w/ a crap load of shit 4mm leds on them, I want to redo the stone side of it with cree xp-e2 amber leds
01:17 AM Wolf__: s/stone/strobe
01:19 AM Wolf__: looks like first need to figure out what the voltage kicking out of the flasher box looks like…
01:22 AM nvz: https://www.youtube.com/watch?v=Y-5xcyJOmHY
01:23 AM nvz: is more what I had in mind :D
01:23 AM Wolf__: lol
01:24 AM Wolf__: I do need to play with the addressable leds more
01:28 AM Wolf__: https://i.imgur.com/82m7rr1.jpg?1 is what I’m working on, 3d printer is almost useful for some things lol right now just a cheap 194 replacement led stuck in the stock cab light socket, the replacement warning light ones I’m pretty sure just have a couple blocking diodes and have a extra lead fed from a flasher controller… guess if I wanted to really drive myself insane I could try to make a full driver w/ MCU to do the fla
01:28 AM Wolf__: patterns =D
01:28 AM Wolf__: also wish I had a cnc router to cut the boards in house
01:31 AM Wolf__: might have to try out spray paint masking some copper and using the diode laser to make the traces
01:32 AM nvz: yeah I wanna get our machine all setup to make boards and cases eventually.. but thats a ways off yet.. first we gotta finish building it this weekend and learn how to use it :P
01:34 AM Wolf__: never simple lol
01:35 AM nvz: yeah.. well we are building a rather large somewhat fancy one for being total n00bs
01:36 AM Wolf__: at least this led thing seems like I’m on the right idea path, make the board layout in cad, export foot prints to circuit design soft, export those to osh park, solder things, watch it fail, repeat
01:37 AM nvz: :D
01:37 AM Wolf__: maybe I should stick making some test boards to make sure the led arrays wont self destruct in there
01:40 AM Wolf__: hopefully your machine plan works better then my cnc plasma lol
01:44 AM nvz: well its largely based on a free plan that works..
01:45 AM Wolf__: yeah, mine was too, but I scaled it up too far lol
01:46 AM nvz: ah I didnt really scale anything up.. I just got the laser from the start, not an afterthought like it was in his, and the motors I used are 425oz-in not 270 like his were.. I also have drivers that go to 128 microsteps his only went to 16 max
01:47 AM nvz: the wood, rails, z axis kits.. etc is all the same
01:47 AM Wolf__: 1.5m + 8mm acme thread rod = total fail, which I should have seen coming lol
01:47 AM nvz: we just wanted something we could work on a 4x8 sheet of material if need be.. eithe rby pushing it through or flipping it around.. so we build a machine big enough to do a 4x4 workable area
01:48 AM nvz: https://www.diybuilds.ca/shop-project-plans.html
01:48 AM BitEvil: :)
01:48 AM nvz: that guy open sources his entire workshop..
01:49 AM nvz: we're building off his cnc router plan got all the rough cutting of the 3/4" birch wood done, and we built a card out of 2x4s to put it on.
01:49 AM nvz: s/card/cart/
01:49 AM Wolf__: I super sized this thing https://openbuildspartstore.com/openbuilds-sphinx-1050-20-x-40/ which wasn’t the greatest idea lol
01:52 AM Wolf__: probably works great at the designed size or even a 1m x 1m but 1.5m way too much whip in the lead screws, so plan b is to design/make new side plates for helical gear rack drive
01:52 AM BitEvil: Anti-whip supports?
01:54 AM Wolf__: its supported at each end, but soon as I try to get any speed the harmonics from the rod kills the steppers, and thats with 425oz ones
01:56 AM BitEvil: I mean support at at least a couple more places along the track with supports that pop out of place when the carridge comes along
01:56 AM Wolf__: not sure how I could make that work inside the C beam the way the carriage is designed
01:57 AM BitEvil: ah - I was thinking of a more exposed screw
01:58 AM Wolf__: right now I’m figuring at worst, I need to take the parts off the plasma build and make a semi normal sized router build from it, then get the gear rack and redo the plasma =)
01:59 AM BitEvil: https://www.youtube.com/watch?v=kkcVWIsXGjk
01:59 AM BitEvil: that's neat
01:59 AM BitEvil: (15s video of follow-block anti-whip deice
02:00 AM Wolf__: hmm, magnets and sliding block
02:01 AM Wolf__: that would work if the side plates of the sphinx kit didn’t have the V-grove rollers inside the C beam =/
02:04 AM Wolf__: this is part of the problem https://openbuilds.com/proxy.php?image=http%3A%2F%2Fwww.cloud3d.ltd%2Fimg%2Fexternal%2Fsphinx-xl-cnc%2Fsphinx-xl-cnc-04-assembled-y-plate.jpg&hash=e86548e459da306977f206c27e885301
02:05 AM Wolf__: but I could make the support thing drag along the end of that carriage
02:09 AM Wolf__: ooh, wait, no magnets needed, the follow support would be pulled by the lead screw thread
02:14 AM Wolf__: BitEvil: I think that concept might work on my build, probably lose 100mm or so of travel but I think a couple 3d printed blocks that fit loosely in the C-beam might work
02:15 AM BitEvil: :)
02:15 AM Wolf__: should take a whole 30sec to model it up lol
02:17 AM Wolf__: but I kinda wanted to build v2 of this plasma table idea lol
02:23 AM Wolf__: helical gear rack drive w/ clearpath servos sounds sexier than acme leads and cheap china steppers =D
03:32 AM gloops: how fast does a plasma cutter need to be?
03:34 AM gloops: with no cutting load and a light carriage, 425oz steppers should be good for 10000mm/min
03:36 AM gloops: probably more in fact, i had my chain drive router doing 15-17k before joint following errors
04:53 AM jthornton: morning
04:57 AM XXCoder: hey
04:57 AM XXCoder: sadly board didnt arrive. aw. at seattle now tho. cable is at calfornia still so I guess they wont arrive at same time lokl
04:58 AM Loetmichel: *haaach* China quality tools... just bent the tip of a key file... thats supposed to break if you exert to much force... :-(
04:59 AM XXCoder: bleh thats not hardened well
04:59 AM Loetmichel: indeed
05:01 AM Tom_L: morning
05:02 AM jthornton: took my uplander to the shop Monday, the intermediate steering shaft is bad, the freon line to the rear is broken, one of the rear brake pads is metal to metal about $700
05:18 AM veegee: _unreal_ I ended up just blasting the whole insides with kerosene through the Y axis hand crank hole, then blasting with compressed air and it all worked out
05:18 AM veegee: but now I have to figure out how to rust proof the insides again since any grease/oil layer that was previously there is now gone
05:20 AM veegee: I fully disassembled the Y axis and rebuilt the nut/screw assembly too. The knee crank bearings and Z axis screw and related bearings are probably depleted of grease now so I have to figure out how to re grease the Z axis feed screw without taking the knee off
05:21 AM veegee: I bought this mill used from a machinist in excellent condition. But somehow inside the knee is full of metal chips. I have no idea how they got there
05:21 AM XXCoder: heh reminds me of one doosan at work
05:21 AM veegee: There was so much gunk that I had to use chlorinated brake cleaner
05:21 AM XXCoder: it was boght over from subdivsion of company that went under
05:22 AM veegee: It worked, but probably stripped the grease from the bearings and such
05:22 AM XXCoder: whole area under mill was crammed full of chips. not just full, crammed full
05:22 AM XXCoder: its still under repairs since some stuff broke by that, like encoders
05:22 AM veegee: everything feels much smoother now but need to figure out how to rust proof the inside of the knee
05:24 AM XXCoder: nice
05:25 AM XXCoder: dunno since it would take quite a lot of abuse
05:25 AM XXCoder: powdercoating I dont think is possible, and dunno if it can take abuse
05:26 AM veegee: I ordered a "rust proofing gun" on amazon. I plan to fill it with gear oil and just coat the inside
05:27 AM veegee: That should work. If not, I have a can of chain wax that I use for my motorcycle. It sprays like a liquid and dries to a very very thick grease that stays put
06:08 AM jthornton: maybe you'll get the board by the weekend
06:08 AM XXCoder: hope so
06:08 AM XXCoder: im getting bit sick bleh but not seriously.
06:16 AM p0g0: I often use a quart sandblaster rig with an oil cocktail at about 10-20psi to undercoat machines.
06:17 AM p0g0: I mix up CLP, winter grade chainsaw bar oil (very sticky), high viscocity oil and some ATF (detergents).
06:18 AM p0g0: That has creep and after the low weight oils gas off, a dense oil coat.
07:35 AM weenerdog: howdy howdy
07:36 AM beachbumpete1: Howdy
07:42 AM jthornton: hi
07:46 AM weenerdog: what yall into today?
07:49 AM beachbumpete1: workin' :(
07:49 AM beachbumpete1: CAD drawing so not like I'm over here breakin' rocks hehe
07:51 AM jthornton: building a polka-yolk
07:54 AM weenerdog: wassat?
08:41 AM jymmmm: Good morning folks!
08:42 AM weenerdog: jymmmm, howdy
08:46 AM beachbumpete1: Mornin Jym
08:50 AM JT-Shop: weenerdog, https://en.wikipedia.org/wiki/Poka-yoke
08:51 AM weenerdog: ha kick ass. new term for me.
08:55 AM weenerdog: i'm, of all things, going back an re-learning plain old c
08:56 AM weenerdog: i'm kinda housebound. my pa had some surgery so i'm playing nurse, and its cold out anyhow. so i broke out my copy of k&r c lol
08:56 AM weenerdog: i learned it in college, but wound up never using it on the job.
09:02 AM JT-Shop: well that part is done... two more to machine and start assembly
09:04 AM weenerdog: pics when you get it choochin, jt
09:07 AM jymmmm: JT-Shop: Is that like a giant boxing glove that smacks you in the face when you make a mistake and learn from it so you don't do it again? I think Acme sells those, ask Willie to be sure
09:08 AM weenerdog: lolol
09:08 AM weenerdog: finger gets near the green button >KA POW<
09:17 AM * jthornton wonders where his Peter Norton's Assembly Language Book for the IBM PC is
09:21 AM jymmmm: jthornton: wood stove?
09:41 AM JT-Shop: 3
10:56 AM Wolf__: veegee: LPS-3 to rust proof surfaces that don’t need accessed often IMO
11:06 AM Loetmichel: *HAHAHAHA!* COworker just came to my desk: "hey, loeti, can you help me? the printer i am just modifying draws 2A at 24V and smells funny..." So i walk over, he switches the printer on: "See, 2amps. What can that be?" ... *BANG* *fishy smell* *alufoil glitter rain* $me: "looks like we just found the problem: you reversed the input electrolytic capacitor!" ;)
11:06 AM radex: hi, I'm new here. i have a Bridgeport mill and i want to connect an original knob as a feed override
11:06 AM radex: using mesa 7i77
11:06 AM radex: how do i configure one of its pins as an analog input in hal?
11:08 AM radex: i tried doung that via pncconfig gui but havent found an analog input option
11:09 AM radex: but 7i77 manual says all field inputs can work as analog inputs so i guess it should be doable
11:51 AM pcw_home: radex: you have to set the sserial mode to 1,2, or 3 to get the analog inputs
11:52 AM pcw_home: (modes are described on page 21 of the 7I77 manual)
11:56 AM pcw_home: they are set by the "sserial_port_0=abcdxxxx" string in the hostmot2 driver configuration information
11:57 AM pcw_home: where 'a' sets the mode for channel 0, 'b' sets the mode for channel 1 etc, so to enable the analog inputs on a 7i77
11:58 AM pcw_home: you would have a config string like "sserial_port_0=10xxxx"
12:10 PM JT-Shop: dang I got a $40 a month raise this year
12:17 PM pcw_home: SS?
12:22 PM JT-Shop: aye
12:24 PM pcw_home: Hmm maybe I'll get one also
12:25 PM JT-Shop: I have to wait two weeks to see if the wife gets one
12:26 PM pcw_home: Katharine starts SS in March
12:27 PM JT-Shop: Nelida started last year and had we known she could have started in 8-2018
12:27 PM JT-Shop: she still works full time at the nail factory
12:29 PM pcw_home: K and I still work but not full time (maybe 5/6 hours a day)
01:07 PM jdh: that's pretty full time
03:44 PM nvz: well, I just spent almost $90 of the $200 I just put into the bank at the hardware store buying nuts, bolts, washers for this machine
03:45 PM nvz: which means I dont have enough in there now for the crap I was gonna order. :P
03:47 PM nvz: a digital tachometer for the spindle, 4 digital ammeters for the PSUs, a Dell Opti 780 SFF, gpu card for it, another parport controller board with a relay, and a spool of 18/4 sheilded wire would've come to like $140
03:48 PM nvz: I had planned to add the digital displays later but I figured if I got em now I could cut the holes to put them in
03:48 PM nvz: thats nearly $40 for all 5 digital meters
03:49 PM nvz: we don't really /need/ all that data when we don't really know wth we're doing yet :D but it'd be useful to know how many amps each PSU is pulling and the rpm of the spindle
03:51 PM nvz: just gotta prioritize I guess.. I'll have more money by friday :P
03:53 PM gloops: so the spindle isnt 3 phase on a vfd?
03:53 PM nvz: I'm debating wheter to get a board like this with one relay https://www.ebay.com/itm/CNC-5-Axis-Breakout-Board-Transmission-Stepper-Driver-Controller-For-Mach3/264566844739 or one like this with 3 relays ebay.com/itm/4-6-Axis-2-5KHZ-USB-Mach3-CNC-Motion-Controller-Card-Breakout-Board-5-12V/392541596463 cause the one we got with our motors/drivers is just a plain old parport breakout with nothing on it.. no
03:53 PM nvz: relays or anything fancy
03:54 PM nvz: and we're gonna have a spindle and laser on it and add who knows what down the road.. cooling..etc..
03:54 PM gloops: i use that board, its probably the most populsr
03:54 PM gloops: popular
03:55 PM nvz: gloops: no the spindle is just a small DC with two wires.. the PSU is a 0-100VDC adjustable that currently has a dial wired to it for manual voltage/speed control
03:55 PM nvz: it has two pins on the psu for on/off (currently jumped to on position) and a 2 and 3 pin header for adjusting output voltage
03:55 PM Deejay: gn8
03:55 PM nvz: gloops: which one the single relay one?
03:56 PM gloops: yeah the single relay
03:56 PM gloops: for a router its got the relay for on/off spindle and also pwm for spindle speed
03:56 PM nvz: thats the one the guy used whose plans we based our machine off of.. but he added a laser later as an afterthought and uses a actual store bought router.. and he manually toggles between his tools
03:57 PM nvz: https://www.diybuilds.ca/uploads/1/1/6/7/116702907/cnc_wiring_diagram_with_laser.pdf
03:57 PM nvz: is how he hooked up both tools to that single relay board
03:57 PM nvz: we don't need the contactor cause ours is a real spindle with its own psu.. and it controls the on/off and power to the spindle
03:58 PM Jymmm: nvz: WHHHATT?! No shark???????????? WTH
03:58 PM nvz: Jymmm: idk what you're referring to :P
03:59 PM gloops: what watt spindle is it nvz?
03:59 PM gloops: and speed is pretty important for a router
03:59 PM Jymmm: nvz: https://www.youtube.com/watch?v=Bh7bYNAHXxw
03:59 PM nvz: hell if I know I didnt buy it, joey did .. it was open box from china
03:59 PM nvz: it works.. hooked it up and tested it.. but dont know any of the details on it
04:00 PM nvz: I was tapped out on funds after buying the motors, drivers, psus, z axis kit, drag chains, limit switches and bearings.. he bought the tools
04:01 PM nvz: the laser is a 7w Neje laser I know that much
04:01 PM gloops: well, not a big thing to change it at a later point anyway if need be
04:01 PM nvz: gloops: yeah thats the advantage of building from scratch.. can change anything easily :P
04:01 PM nvz: we still gotta learn to actually run the machine so.. tools arent real important yet..
04:01 PM nvz: just needed something to get started with
04:02 PM nvz: personally I think we'll get more use out of the laser for etching things to start with
04:02 PM gloops: a lot of the small chinese dc spindles are 500w or less, and 12000rpm, not quite enough really, some get by with them though, suppose it depends on the job
04:03 PM nvz: I watched some videos of a lil 6x6in machine that uses the Neje 7w laser.. and it did well with metal dog tags, copper, wood, and other softer material
04:03 PM gloops: how big is your work area?
04:03 PM nvz: its going to be about 4x4ft workable area
04:04 PM gloops: oh thats a fair size then
04:04 PM nvz: yeah we wanted to be able to do 4x8 materials if need be.. either pushing em through or flipping em around
04:04 PM nvz: we built a cart on wheels to put the machine on
04:05 PM gloops: i wish mine was on wheels sometimes lol
04:05 PM nvz: though we haven't yet put any leveling screws or locking wheels on it so.. that prob needs to be done too
04:06 PM nvz: http://nvz.farted.net/cnccart.mp4 is a time-lapse video of us building the cart
04:07 PM nvz: so far we got that done, all the wood rough-cut on the table saw and the bridging together and screwed to the base of the machine based on this guys plans https://www.diybuilds.ca/uploads/1/1/6/7/116702907/cnc_table_plans.pdf
04:08 PM nvz: and we got all the hardware, rails, belt, pulleys, motors, drivers..etc.. just mostly need a computer and probably a better control board and to finish assembling it
04:09 PM gloops: well if the router doesnt pay you should get some roofing work anyway lol
04:10 PM nvz: we're flipping a house right now..
04:10 PM nvz: http://nvz.farted.net/house/ I gotta upload more pics yet..
04:11 PM gloops: probably need some diagonal bracing or panel the sides
04:11 PM nvz: gloops: the cart you mean? I put some blocks in on the corners to sure it up a bit
04:11 PM nvz: its pretty solid
04:12 PM gloops: is this cart the actual machine base?
04:12 PM nvz: no, the machine is built out of 3/4in furniture grade baltic birch
04:12 PM nvz: and the machine base is a 5x5ft sheet of it that sits on top of that
04:12 PM nvz: sticks out past that cart which is only like 4x4
04:13 PM nvz: the base of the machine is two 5x5 sheets of that birch with 3 pieces of it going one way and 3 going the other interlocking to form a bridging
04:13 PM gloops: well again i suppose you can add more bracing if and when required
04:14 PM nvz: gloops: I posted the wrong plans :P https://www.diybuilds.ca/uploads/1/1/6/7/116702907/cnc_plans.pdf
04:14 PM nvz: we are using his cnc plan with slightly different motors/drivers and such.. but his table we didnt use his plans at all we used 2x4x8 for that
04:15 PM gloops: a ply box is a very strong structure, there have been people in here with play machines, one made parts for model aircraft - kept the shop going with it
04:16 PM gloops: Loetmichel has vids of a ply machine he made cutting aluminium just fine
04:16 PM nvz: yeah its a heavy machine thats for sure.. real strong
04:17 PM gloops: the enemy with wood is moisture, needs to be well sealed, warping, bowing tc
04:22 PM nvz: yeah joey said he has some stuff and bought a can of some kinda crap.. idk.. that sort of thing isnt something I have a lot of experience with
04:23 PM nvz: but he intends to seal the base, I told him that _unreal_ had recommended that as well and he liked the idea.. so I'm gonna leave that up to him
04:24 PM nvz: the guy who made those plans just used brads, screws and wood glue.. he didnt seal anything
04:25 PM nvz: I bought enough nuts to double nut all the bolts for the belt tensioners and rail bearings..
04:25 PM nvz: that much I had thought of.. putting a 2nd nut on to keep the first from backing up
04:26 PM nvz: and I got washers to go on both sides of all the bearings and between the nut(s) and the wood\
04:27 PM nvz: the v-groove bearings for the rails use a 3/8" bolt and the belt tensioners are 1/2" bolts I'll put two bearings together on each tensioner bolt with a washer on either side to act as a guide for the belt..
05:07 PM Jymmm: If you have a 40gallon water heater, what does that relate to a tankless? They seem ot be rated in 8.4 GPM
05:10 PM Elmo40: since they don't store anything they won't be rated in volume.
05:10 PM Elmo40: and really, how fast can a 40gal tank heat up? not very.
05:12 PM Jymmm: Well, it's not the recovery time, but the accptable usage of 40 gallons of "hot" water before it goes cold.
05:13 PM Elmo40: that is the other problem. while in use it is never 40gal of 'hot' water. cold is always refilling it when hot is leaving.
05:14 PM Jymmm: That still doens't help is slecting the "equivilent" of a tank
05:14 PM Elmo40: and 8.4gpm is high!
05:15 PM Elmo40: shower is about 3. kitchen sink 2 or lower. how many people live in the house?
05:15 PM Jymmm: only one shower at a time dues to 24 psi
05:16 PM Elmo40: then you don't need anything like the 8.4gpm
05:16 PM Elmo40: that will be a large unit
05:16 PM Elmo40: find a ~5
05:16 PM Elmo40: a unit that heats 4 gallons per minute can handle a shower plus one appliance operating at the time.
05:18 PM Jymmm: JT-Shop: EXCELLENT gas pipe sizing info, including formula... https://images.homedepot-static.com/catalog/pdfImages/01/01e4f249-cf20-449c-9fac-d5be2d01c28d.pdf
05:18 PM Jymmm: Elmo40: That works
05:43 PM Jymmm: At $120, I almost want to buy this just to have on hand just in case... https://www.amazon.com/VEVOR-Stainless-Liquefied-Petroleum-Wall-Mounted/dp/B07CPPGBV6/
05:46 PM Tom_L: just take a cold shower
05:47 PM Jymmm: Tom_L: you first, in 29F water
05:47 PM Tom_L: i think you need a larger gas line for those
05:48 PM Jymmm: Tom_L: It'll run off a 5gal propane tank I believe, but I have a 3/4" and 1/2 already
05:49 PM Tom_L: iirc 3/4 was recomended for one i looked at a long time ago
05:49 PM Tom_L: possibly even a 1" supply from the meter
05:50 PM Jymmm: Tom_L: I know I have 3/4 from the tank to the house, but I'm not sure what it is from the house to the existing heater, but it's only like 4ft difference
05:51 PM Jymmm: this is LPG, not NG, not that it matters all that much
05:51 PM Tom_L: most likely 1/2"
05:57 PM Jymmm: Tom_L: You are gonna make me go outside in -150F weather just to prove you right, aren't you?!?!?!
05:57 PM Tom_L: y of course
05:59 PM Jymmm: Tom_L: It took me an hour to finally get the wood stove going properly. Already got my 4 buckets of firewood for the day, nope, not goin outside to look =)
06:14 PM * jthornton used to take cold showers on the sailboat... in the summer
06:15 PM Jymmm: jthornton: and the air temp was what?
06:16 PM Tom_L: just think of it like those idiots that jump in the artic water in the dead of winter...
06:20 PM jthornton: sailboat... summer...
07:13 PM ziper: is there any option for measuring surface roughness between just touching and feeling and spending a couple thousand dollars on an instrumant?
07:16 PM Jymmm: a string and a flashlight?
07:16 PM ziper: how do I do that?
07:17 PM Tom_L: are you talking about finish callout?
07:18 PM ziper: I don't know, i've never had to make anything to a described finish
07:18 PM ziper: I just stop when I think its good enough
07:19 PM Tom_L: well there are finish gauges
07:19 PM Tom_L: but there are other ways to determine it too
07:19 PM Tom_L: comparitor or surface roughness gauges

07:21 PM Tom_L: alot of drawings will specify a finish callout
07:32 PM ziper: comparitor you literally just touch it and see what it feels like?
07:32 PM ziper: which one is closest?

08:01 PM Jymmm: Hey, you never know
08:02 PM Jymmm: Rab: I put up a WANTED : Honda EU2000i Generator, and got a response, picked it up for $300 in perfect working order. The guy was seeeling it for his friend that had to go back to Mexico and needed the cash.
08:03 PM tiwake: Jymmm: 0.o
08:03 PM Rab: ...Sounds legit.
08:05 PM Jymmm: tiwake: ???
08:15 PM calvind47: Hello, is anyone able to help me with figuring out why apt-key is not accepting the build bot key on a new install
08:17 PM Tom_L: maybe the key is invalid?
08:18 PM Tom_L: what's the install?
08:20 PM calvind47: never mind someone on the forum just helped me, I needed to add :80 after the key server address
08:20 PM calvind47: but thank you for responding
08:22 PM Jymmm: calvind47: JUST FYI that sounds like port 80 ( :80) which is web stuff typically (can be used for other things too)
08:23 PM calvind47: I was following http://linuxcnc.org/docs/devel/html/plasma/plasmac-user-guide.html#_getting_linuxcnc_with_the_plasmac_add_ons
08:23 PM calvind47: this got it to work
08:23 PM calvind47: sudo apt-key adv --keyserver hkp://keys.gnupg.net:80 --recv-key E0EE663E
08:24 PM calvind47: should I poke someone about updating the instructions ?
08:24 PM Tom_L: he's asleep
08:24 PM Tom_L: well probably
08:35 PM calvind47: thank you
09:34 PM norias: thank
09:34 PM norias: you
09:34 PM norias: falletinme be mice elf
09:34 PM norias: again
09:36 PM ziper: Tom_L, I almost bought a comparator a couple months ago
09:36 PM ziper: I didnt know those could do surface finish
09:36 PM ziper: all the handheld ones are a couple grand, at least
09:38 PM Tom_L: i'm not entirely sure of what their limitations are
09:39 PM ziper: the surface in quesion is smoother than 1000 grit sandpaper, so I'm about at my limit with touch and feel
09:39 PM ziper: oh well, i'll just do the best i cant
09:40 PM Tom_L: then you should compare it with an inspection sample
09:46 PM _unreal_: veegee, I figured something would work
09:47 PM _unreal_: calvind, :80 port 80?
09:48 PM Tom_L: yes
09:48 PM Tom_L: not sure why it has to be specified though
09:49 PM Tom_L: 80 is a default
10:46 PM calvind: so someone on the forum said it may be do to being behind a firewall, but in this day and age I would assume most computers are behind a firewall
10:46 PM calvind: and yes port 80
10:49 PM calvind: I have a moving motor tonight and I am now running 2.9
10:50 PM calvind: tomorrow I am going to poke at why the 7I96 config tool instructions don't work for the linux image I loaded
10:52 PM Tom_L: 2.9 is the master branch where new things are added etc
10:53 PM Tom_L: i'd learn about the ini and hal files and just use the config tool as a starting point
10:53 PM Tom_L: and now that you're started just edit the ini and hal files as needed and not use the config tool
10:56 PM calvind: ah, not my first machine with linux cnc have built a few machines using 7I76E boards, I am switching over to using the 7I96
10:57 PM Tom_L: config tools will only take you so far...
10:58 PM calvind: i completely agree, I just wanted to grab the initial config from and get a motor moving. I was going to run down the installer issue so the documentation could get updated
10:59 PM calvind: I was able to run it manualy and got what I needed, but I work in software and reporting bugs is just good habit now
11:00 PM Elmo40: along with commenting your code.
11:01 PM calvind: I have reinstall the machine image 3 times tonight, just to confirm all my notes are correct, so testing documentation as well :)
