04:15 AM Loetmichel: *shiver* ... its cold in germany... MAN audi, really? had to remove the whole rear light unit from the hatch to change the indicator bulb... OK, took only 10 minutes to help the coworker out, but without a ratchet, 10mm head AND an extension: no chance. What are you thinking, audi?

07:16 AM JT-Cave: 16°F
07:30 AM * JT-Cave thinks it's better to go ahead and start some fires now
08:41 AM perry_j1987: -13 here
10:17 AM Bleepshop: Loetmichel: Uhhh, They were thinking there'd be a tidy profit for the service center for replacing a $1 bulb?
10:17 AM CloudEvil: Modern LED lamps on cars have remvoed this issue.
10:18 AM CloudEvil: There you instead replace the whole cluster when it fails, for $1300.
10:19 AM Loetmichel: Bleepshop: probably
10:20 AM Loetmichel: CloudEvil: yes, and thats ok, IF that led is meant for the "lifetime" of the car
10:20 AM CloudEvil: The warranty lasts 3 years.
10:21 AM Loetmichel: point is that a tungsten filament bulb usually has to be replace every couple years anyway, while a led cluster is usually engineered for 10+ years.
10:22 AM Loetmichel: unless you get the "monday" piece
10:23 AM Loetmichel: also there is a law in germany as far as i am informed that states that any "consumable" like bulbs and window water and so on HAS to be serviceable without tools
10:23 AM roycroft: there are some tungsten filament bulbs that were made by thomas edison himself that are still working
10:23 AM Loetmichel: roycroft, please educate yourself about "average lifetime"
10:23 AM roycroft: :)
10:24 AM roycroft: the average lifetime has decreased over the years
10:24 AM Loetmichel: MTBF of the usual 21W indicator bulb is a few 100 hours, MTBF of a led cluster is more in the 100k hours.
10:25 AM CloudEvil: Manufacturer claimed MTBF.
10:25 AM Loetmichel: if you say so, CloudEvil.
11:09 AM CaptHindsight[m]: roycroft: you mean made by someone he paid or cheated into making :)
11:11 AM roycroft: more than likely
11:11 AM roycroft: made in his lab
11:11 AM roycroft: there
11:11 AM roycroft: that fixes it
11:12 AM CaptHindsight[m]: 258 k here
11:19 AM roycroft: justice breyer is retiring
11:20 AM * roycroft waits for moscow mitch's convoluted "logic" for his argument that a new justice cannot be appointed by president biden
11:21 AM roycroft: fortunately his argument is irrelevant
11:26 AM roguish[m]: roycroft: where did you see that news?
11:29 AM roycroft: i just heard it on npr
11:30 AM roycroft: it's breaking on cnn now
02:09 PM Rab: Anyone have any strong opinions about label makers?
02:09 PM JT-Shop: yes
02:11 PM Rab: I need labels for some sensors which will be buried, they need to be tough enough to withstand weather, abuse, washing, etc. Brady seems to make a ~$100 handheld with labels that are claimed to be all-weather.
02:12 PM Rab: There might be heavy-duty tapes for our Brother labelers, but I can probably justify the entry-level Brady stuff if it's more robust.
02:15 PM Rab: "Maximum Labels Per Day: 100" https://www.bradyid.com/label-printers/bmp21-plus-portable-label-printer-pid-139535
02:16 PM JT-Shop: I have this one https://labelworks.epson.com/printers/lw-px700.html as well as an assortment of brother and a kroy the epson is the best
02:16 PM Rab: I guess the thermal head overheats under heavy use?
02:16 PM Rab: Great, thanks!
02:16 PM JT-Shop: great tech support too
02:17 PM JT-Shop: the epson does not waste tape or heat shrink like the others do
02:17 PM Rab: Epson's LW-PX700 can save you time by printing various length labels all in a single strip of labels, separated only by Epson’s automatic half-cut feature that cuts only the label, not the backing. <-- incredible
02:19 PM JT-Shop: and that's a sweet feature for sure no fumbling with a bunch of loose heat shrink labels
02:23 PM Rab: Ever seen the Epson labels degrade?
02:27 PM enleth: huh, I was just looking for a label printer and so far I'm disgusted with the dymo rhino "professional" printers but with no clear winners
02:27 PM enleth: now that might change
02:32 PM JT-Shop: I haven't had the PX700 long enough to say but I will add it does have a lifetime warranty
02:32 PM JT-Shop: https://labelworks.epson.com/product-brochures-manuals
02:43 PM roycroft: i have the same label printer as jt-shop
02:43 PM roycroft: and i have been very happy with it so far
02:47 PM roycroft: the half cut feature is great, but the one feature i really like the best, and that will pay for the cost of the printer in no time, is the rewind feature
02:47 PM roycroft: when you cut off a label, it can rewind the label tape back into the machine, so you only waste 2mm of tape
02:47 PM enleth: shit, it doesn't seem to be available over here
02:48 PM enleth: and of course they had to name one of their photo printers "PX700" so it clogs up search results
02:48 PM roycroft: it's japanese
02:49 PM roycroft: there may be a different version for europe
02:49 PM roycroft: japanese manufacturers often market their products with different names/model numbers in different parts of the world
02:52 PM roycroft: you might search on epson labelworks
02:52 PM enleth: looks like they just don't sell the PX series here at all
02:52 PM roycroft: bummer
02:52 PM roycroft: it really is a nice printer
02:53 PM roycroft: and the price is really good too - i was surprised at how inexpensive it is
02:55 PM roycroft: https://www.epson.eu/products/printers/label-maker/labelworks-lw-z700fk-qwerty?productfinder=labelworks
02:57 PM roycroft: so it does look like it's available in europe, but with a different model number
02:57 PM Tom_L: same feature set?
02:58 PM roycroft: it appears to be similar, if not identical
02:58 PM Tom_L: maybe different char set or symbols
02:58 PM enleth: yes, you were right, just found it myself
02:59 PM enleth: this naming is bullshit, but it appears to be the same device
02:59 PM roycroft: since it's europe, a $120 printer is probably more like 175 euros
02:59 PM roycroft: but it's still worth it imo
03:01 PM enleth: it's almost 400
03:02 PM roycroft: yeah, i was wrong
03:02 PM roycroft: it's 249 euros
03:02 PM roycroft: https://www.amazon.de/-/en/LabelWorks-Thermal-Transfer-Printer-39-EAN13/dp/B01NAZ6QZ5
03:03 PM roycroft: still worth considering
03:04 PM roycroft: you could probably buy it in the us for $120 and have it shipped for a lot less, but you wouldn't get the lifetime warranty that way
03:05 PM roycroft: i recently labeled some ports on a network switch, and the printer was very nice for that
03:06 PM roycroft: i told it the distance between each port, told it to use a | as a separator, and then entered the list of port labels in order
03:06 PM roycroft: and it printed one long strip that was perfectly spaced
03:07 PM roycroft: i like my p-touch labelers, and won't get getting rid of them, but they are general-purpose labelers
03:07 PM roycroft: the epson is designed specifically for electronics/network labeling
03:08 PM enleth: what's the smallest heatshrink it accepts?
03:09 PM roycroft: 3mm, iirc
03:09 PM roycroft: and it does about a 2:1 shrink
03:10 PM enleth: I need to label 0.75mmsq (~26awg?) wiring in control cabinets pretty often
03:10 PM roycroft: yes, 3mm is the smallest
03:10 PM enleth: that sounds like it would do
03:10 PM roycroft: it might not be really tight
03:10 PM roycroft: but it should fit snugly
03:11 PM roycroft: they have a shink tube matrix - i'm looking for it now
03:11 PM enleth: BTW, I need a tiny, battery powered heatgun for those
03:11 PM enleth: that doesn't seem to be a thing
03:11 PM roycroft: you should be able to make one
03:13 PM roycroft: https://labelworks.epson.com/amfile/file/download/file/37/product/818/
03:13 PM roycroft: you might find that interesting, although it's not what i was looking for
03:13 PM roycroft: https://labelworks.epson.com/amfile/file/download/file/106/product/817/
03:13 PM roycroft: that is what i was looking for
03:14 PM roycroft: the 3mm tubing is actually 5mm id and shrinks to less than 3.0mm id
03:14 PM roycroft: it's actually 5.9mm id originally, but is nominally 5mm
03:15 PM Rab: enleth, I use my hot air reflow station a lot for heatshrink. This isn't cordless, but it's compact and handheld: https://www.aoyue3d.com/en/pro/default.asp?id=91
03:16 PM Rab: Other than that, heat gun seems rough on battery power...maybe a butane pocket torch would work.
03:16 PM enleth: Rab: ah, right, I forgot those self-contained soldering guns were a thing
03:17 PM enleth: Rab: it might work with a really narrow nozzle
03:17 PM enleth: but a corded handheld soldering gun is fine too
03:24 PM roycroft: a crème brûlée torch would work fine too
03:25 PM JT-Shop: I use my Tower Hobbies heat gun
03:25 PM roycroft: enleth: i don't have any 26ga wire handy, but i just put a 3mm label on a piece of 24ga wire
03:25 PM roycroft: my heat gun is still waiting for parts, so i had to shrink it as best i could using my kitchen stove
03:26 PM roycroft: i can move the label, but it stays in place on its own
03:26 PM enleth: roycroft: I'm not taking a live flame into a cramped wiring cabinet that had oil leaking into it for the last 40 years
03:26 PM Rab: This is my favorite heat gun for electronics and heat shrink. It has a low air velocity so it shrinks very effectively without blowing stuff all over the place. https://www.masterappliance.com/master-mite-heat-gun/
03:27 PM Rab: The motor died on the one at work and I replaced it, unfortunately I wasn't too impressed by the internal construction. But I don't usually see them fail.
03:27 PM JT-Shop: I had a brain fart and wired up the lean-to outlet to 240vac and plugged my milwaukee heat gun in and it didn't last a second
03:28 PM roycroft: that is the exact model i have, rab
03:28 PM roycroft: i've had it for about 30 years
03:28 PM roycroft: i recently dropped it on a concrete floor, and the internal mount for the blower fan broke
03:28 PM roycroft: i was able to order a new case for it
03:28 PM roycroft: but they've changed the switch, so i had to order a new switch to fit the case
03:29 PM roycroft: i think it's great that it's lasted that long, and even better that they still make parts for it
03:31 PM roycroft: enleth: roycroft.us/Epson
03:31 PM roycroft: that's the 24ga wire
03:31 PM roycroft: with the 3mm shrink tubing
03:32 PM roycroft: rab: when they first made that heat gun it had a wooden handle
03:34 PM roycroft: if you want a tighter fit on small wires you could cut some pieces of 2mm shrink tubing, slide one over the wire, and slide a 3mm label over it and shrink them together
03:34 PM roycroft: i think that if the printable shrink tubing were any smaller than 3mm the labels would be hard to read
03:38 PM roycroft: https://www.masterappliance.com/products/butane-tools/ultratorch-soldering-irons/
03:38 PM roycroft: butane soldering irons, with hot air tips available
03:40 PM roycroft: https://www.masterappliance.com/40061-attachment-1-4-pinpoint/
03:40 PM roycroft: and a 1/4" pinpoint attachment for my heat gun
03:42 PM Rab: roycroft, ooo, neat
03:43 PM roycroft: yeah, i don't have that attachment
03:43 PM roycroft: i have the curved shield, which i use on the bench a lot
03:44 PM Rab: Yeah, I typically use the shield.
03:44 PM roycroft: https://www.masterappliance.com/40060-attachment-heat-shrink-up-to-1-o-d-standard/
03:44 PM roycroft: that one
03:45 PM Rab: The pinpoint doesn't seem to be a popular item, I don't see a good source besides straight from Master.
03:45 PM roycroft: i wish i had seen it on their website a few days ago
03:45 PM roycroft: i just ordered the switch last week
03:45 PM roycroft: they charge a lot for shipping - if i had known about that i'd have added one to my order
03:46 PM roycroft: they have some other reduction attachments as well
03:46 PM roycroft: but they are 5/16" and 3/8"
03:46 PM roycroft: i think 1/4" is best for my use
03:47 PM roycroft: i have a butane soldering iron, but no hot air attachment for it
03:47 PM roycroft: i don't even remember what brand it is - i've had it for probably 35 years, and don't use it much these days
03:48 PM roycroft: rab: sign up for their mailing list and they'll give you a free shipping code, but i think there's a $30 minimum to use the code
03:50 PM Rab: Odds are that if I have to order from Master, it'll be more than $30. I think the motor was $60 some years ago.
03:50 PM Rab: That might have been a stocked part at Mouser Electronics.
03:53 PM roycroft: it's been ages since i purchased my heat gun, but i think it was about $75 at the time
03:54 PM roycroft: i see that it's double that now
03:58 PM roycroft: my only annoyance with master appliance is the same annoyance i have with epson - they are both located in wisconsin, and when i call them i have to deal with people with that extremely annoying midwest flat vowel accent
03:58 PM roycroft: that accent is one of the reasons i moved away from chicago
04:08 PM JT-Shop: I emailed a question to osborne mfg and the president of the company answered the email
04:14 PM CaptHindsight[m]: the label maker question comes up so often that maybe someone should make a kickstarter with an open controller for some readily available model
04:16 PM roycroft: what would be the advantage of that vs. just buying the epson and using it?
04:18 PM _unreal_: roycroft, I am going to fuck with your head, WATCH THIS https://www.youtube.com/watch?v=IF8U8nd5oSM
04:19 PM _unreal_: roycroft, ?
04:19 PM roycroft: i've seen that video
04:19 PM _unreal_: damn you
04:19 PM roycroft: and i've given up the idea of an automated dust shoe
04:19 PM _unreal_: I assume that was your source for the idea
04:20 PM _unreal_: or a model method to consider
04:20 PM roycroft: i've decided that it's important to have an independent dust shoe, but manual adjustment is fine
04:20 PM roycroft: that was not the source for the idea
04:20 PM roycroft: i'd likely have given up on the idea right away if that was the source :)
04:21 PM roycroft: but i did see it while i was researching methods to do it
04:21 PM roycroft: the source of the idea was actually my watching other videos of cnc routers with the dust shoe fixed to the spindle
04:21 PM roycroft: and seeing how horribly that works
04:23 PM roycroft: i determined that an independently adjustable dust shoe would be much better, and was certain i was not the first person to think of that, so i did some searching and found a number of articles/videos
04:23 PM XXCoder: fancy shoe
04:23 PM XXCoder: i like idea of brush held by magnets
04:24 PM roycroft: but i'll say again what i've said before
04:24 PM roycroft: marius hornberger is more in the business of generating clicks than making parts
04:24 PM roycroft: and his design is very good at generating clicks
04:24 PM _unreal_: XXCoder, my machine uses magnets and I have push down twist holders
04:25 PM roycroft: using magnets to hold the shoe on is pretty common, and something i'll likely do
04:27 PM XXCoder: cool
04:30 PM roycroft: i just found my butane soldering iron, and it does have a hot air attachment - i didn't think i had one
04:30 PM roycroft: the brand is archer, so it's a radio shack product
04:30 PM roycroft: only found in antique stores now, i suppose
04:31 PM roycroft: it's not self-igniting, but it has a flint sparker on the end of the cap
04:31 PM XXCoder: or homes of old fogies ;)
04:32 PM roycroft: i'll have to gas it up and see if it still works
04:32 PM roycroft: if it does, i can use it until the switch for myheat gun arrives
04:51 PM JT-Shop: geez found records from building my house and it took me 5 months to get it dried in
04:56 PM XXCoder: 5 mont to dry out? or did I misunderstand what dried in mean'
04:57 PM JT-Shop: roof shingled, outside has house wrap on it
04:57 PM JT-Shop: IE you won't get wet inside when it rains
04:57 PM XXCoder: ahh ok
04:58 PM JT-Shop: 12-18-97 the basement guys were done and it was my turn
04:58 PM CaptHindsight[m]: JT-Shop: how long ago did you build it? Was it a weekend project since it was before semi-retirement?
04:59 PM Rab: Lots of houses going up here. Sometimes permitting gets hung up, or something, and they sit for weeks with no activity. Makes me nervous when they sit for a long time with no wrap over MDF.
04:59 PM Rab: Or the wrap starts to tear off in the wind.
04:59 PM JT-Shop: mdf?
04:59 PM Rab: Er, OSB...MDF would make poor sheathing.
04:59 PM JT-Shop: CaptHindsight[m], well I started the day after the basement guys left
04:59 PM CaptHindsight[m]: maybe OSB?
05:00 PM CloudEvil: OSBs weather proofness has improved, for the good grades
05:00 PM JT-Shop: I remember the feeling quite well after the lumber was dropped off and he was gone...
05:01 PM CaptHindsight[m]: I have seen projects get hung up for years without doors and windows
05:01 PM Rab: My bro-in-law sheathed his addition in ZIP System® OSB with integrated moisture barrier, looked legit.
05:01 PM JT-Shop: I was a bit in shock like wtf did I get myself into
05:01 PM CaptHindsight[m]: I have wondered about how they held up after they were finished
05:01 PM JT-Shop: after a few moments I decide I better get busy
05:02 PM CaptHindsight[m]: JT-Shop: a good time not to get sick
05:03 PM JT-Shop: the big motivation was to get dried in and get the bathroom downstairs finished out and move in
05:03 PM Rab: But few new builds here use branded OSB.
05:04 PM CaptHindsight[m]: I was paid to help some acquaintances out with their home additions...... and never again
05:05 PM CaptHindsight[m]: i tried to rehab a house we lived in when I was a single dad with little kids
05:06 PM JT-Shop: just asking for trouble there
05:06 PM CaptHindsight[m]: I did manage to get some floors redone and walls painted
05:07 PM JT-Shop: I added on to a house in Pascagoula ms a long long time ago and it was framed with oak sometime around ww2
05:07 PM CaptHindsight[m]: re-plumed one area, then house prices tripled and i sold it as is
05:07 PM JT-Shop: I had to drill holes for the nails to tie rafters in to the existing
05:09 PM JT-Shop: hmm the Insight has a new map update
05:09 PM CaptHindsight[m]: this was similar, house was built in 1892, Chicago Workers House, frame 2 story with basement and tall attic
05:09 PM CaptHindsight[m]: was already 4 apartments when I got it
05:11 PM CaptHindsight[m]: house/cottage https://workerscottage.org/whatis.html
05:14 PM CaptHindsight[m]: JT-Shop: how close to the inch was the old lumber?
05:14 PM JT-Shop: it was rough cut oak so 2" x 4"
05:15 PM CaptHindsight[m]: heh similar, so getting things to match up was extra work
05:16 PM CaptHindsight[m]: at some point a pipe burst in the past and warped some floor joists by 1-2 inches
05:17 PM CaptHindsight[m]: their fix was to place a new plywood floor over the original, so some rooms had a 2 inch step at the doorway
05:17 PM CaptHindsight[m]: i don't miss that place
05:20 PM * JT-Shop is designing some chicken stairs
05:22 PM CaptHindsight[m]: JT-Shop: did you visit the local hobby shops miniature dimensional lumber section? :)
05:22 PM JT-Shop: we don't have hobby shops but we do have hobby lobby lol
05:23 PM JT-Shop: no, using 1 by for the stringers and red oak for the treads
05:24 PM JT-Shop: most chicken tenders use a ramp with cleats... I'm different
05:25 PM Tom_L: jt doesn't go to the hobby shop, he chops a tree down and makes lumber to build with
05:25 PM CaptHindsight[m]: no catwalk either
05:25 PM Tom_L: they're not cats
05:25 PM JT-Shop: no cats in my hen house
05:25 PM JT-Shop: and yep I make my lumber
05:26 PM * JT-Shop listens to Roger Miller Chug-A-Lug
05:26 PM roycroft: well i was just a very bad boy
05:26 PM CaptHindsight[m]: I think Hobby Lobby has one half an isle that has traditional hobby items
05:26 PM roycroft: i paid off a 0% apr promo on time
05:26 PM roycroft: so no finance charges for the cc company
05:26 PM roycroft: they hate it when that happens
05:27 PM * roycroft has never stepped foot in a hobby lobby store, although there is one in springtucky now
05:28 PM JT-Shop: it's mostly arts and crafts but they do have a good picture frame department
05:28 PM JT-Shop: I had them frame a family photo when I was a ute and I had a tie on!
05:29 PM JT-Shop: strange that my dad was not in that photo
05:30 PM CaptHindsight[m]: small selection of fabrics, lots of craft items for kids and half the store seems to be items to clutter your home and collect dust in various stages of completeness
05:30 PM JT-Shop: I wonder how long I should wait before refunding the money to the guy that selected free shipping when it's not offered for what he bought
05:31 PM JT-Shop: yep that's a pretty good assessment of it... I do get leather for my air filters for the 2012 Spyder
05:31 PM CaptHindsight[m]: https://www.hobbylobby.com/Home-Decor-Frames/Mirrors-Wall-Decor/c/3-109 who doesn't want this? :)
05:32 PM * JT-Shop doesn't even lool
05:32 PM JT-Shop: or look even
05:32 PM JT-Shop: hmm gold dust woman
05:33 PM CaptHindsight[m]: it's like a Salvation Army store when the things are actually new
05:33 PM JT-Shop: LOL
05:34 PM JT-Shop: sunset in 2 minutes and the Queens are still milling about outside in the run
05:36 PM XXCoder: good thing im not a vampire lol
05:37 PM XXCoder: mirrors and cprsses :P
05:39 PM CaptHindsight[m]: https://en.wikipedia.org/wiki/Tchotchke
05:40 PM CaptHindsight[m]: https://en.wikipedia.org/wiki/Bric-%C3%A0-brac
05:48 PM CaptHindsight[m]: ~$100 https://linuxgizmos.com/quad-core-atom-based-raspberry-pi-lookalike-ready-to-roll/
05:50 PM CaptHindsight[m]: the Ethernet is on PCIe
06:03 PM _unreal_: ok.... I just woke up
06:03 PM _unreal_: crapy day at work very tired....
06:03 PM _unreal_: time to grab the kid and run to lowes or homedepot to get a board cut to the right dimentions for the BASE of the new cnc machine
06:05 PM _unreal_: and wow I just found out meatloaf died
06:22 PM roycroft: i need a nema23 motor with a long shaft
06:22 PM roycroft: does anyone know where to find one?
06:22 PM roycroft: i find standard length shafts and double ended ones easily, but i'm not finding any long shaft nema 23 motors - just some nema 17
06:25 PM roycroft: oh, and 3nm/425oz*in
06:25 PM Tom_L: how long?
06:25 PM Tom_L: might not find one
06:26 PM roycroft: the ones i have are 24mm
06:26 PM roycroft: i need another 10mm or so
06:26 PM Tom_L: make a special coupler instead
06:27 PM roycroft: i suppose i could mount this motor lower, install a shaft in the drive gear, and use a coupler to join them
06:27 PM roycroft: that is probably what i'll have to do
06:27 PM Tom_L: or change the design to acomodate available parts
06:31 PM roycroft: https://roycroft.us/CNC-Router/Z-Axis-Motor.jpeg
06:31 PM roycroft: the motor shaft only goes about halfway through the gear
06:32 PM roycroft: and i can't lower the ball screw gear
06:32 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Z_Motor_Mount1.jpg
06:33 PM roycroft: i would prefer not to mount the motor from above
06:33 PM Tom_L: wait.. that wasn't the fina
06:33 PM Tom_L: l
06:33 PM roycroft: this machine is already way taller than i want it to be
06:33 PM roycroft: i hope that's not final
06:33 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Z_Motormount4.jpg
06:34 PM Tom_L: my shaft goes most of the way thru it seems
06:34 PM Tom_L: that's what i was looking for..
06:34 PM roycroft: i haven't decided how to make the adjuster slots yet
06:35 PM roycroft: if i hang the motor down a bit lower and put an extension on the shaft it might be easier to make the adjusters
06:35 PM roycroft: i have plent of room below
06:35 PM Tom_L: i'm not sure i'd do that but i'm not there
06:35 PM roycroft: even though my actual motors are longer than the one in that drawing
06:35 PM Tom_L: they're probably the same as mine
06:35 PM Tom_L: or maybe a tad shorter
06:36 PM roycroft: they look the same
06:36 PM roycroft: i have one in front of me
06:36 PM Tom_L: i don't :)
06:36 PM roycroft: the motor body is 112mm long
06:36 PM Tom_L: i doubt they make them longer than mine
06:37 PM Tom_L: 570 in oz
06:37 PM roycroft: from the bottom to the mounting face
06:37 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Y_Motormount2.jpg
06:37 PM roycroft: mine are 425oz in
06:37 PM Tom_L: better view of a motor
06:39 PM roycroft: i think a well-made adapter would work fine
06:39 PM silopolis[m] is now known as silopolis_vm[m]
06:39 PM roycroft: i had considered direct coupled, but i want the option of doing a 1:2 reduction
06:40 PM Tom_L: my X and Y are but Z isn't
06:40 PM roycroft: i figure if i use a timing gear setup like that, i can change the ratio to hwatever works best for me
06:40 PM roycroft: i'll probably buy two of the gears for the motor, so i can try 1:1 and 1:2
06:41 PM roycroft: x and y i'll run 1:1, i'm sure, but i'll still use the timing gears, because i don't want the motors sticking out the side of the machine
06:41 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/X_Motormount1.jpg
06:41 PM Tom_L: X
06:41 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/X_MotorMount2.jpg
06:41 PM Tom_L: not the prettiest weld
06:42 PM roycroft: it looks like it works
06:42 PM roycroft: and that is what matters
06:42 PM Tom_L: it's solid and aligned
06:43 PM roycroft: if it hasn't fallen off yet you did fine
06:43 PM Tom_L: nope
06:43 PM roycroft: and are likely still able to count to ten on your toes
06:43 PM Tom_L: and/or fingers
06:44 PM Tom_L: my plan is to keep it that way
06:44 PM roycroft: where do you get your timing gears?
06:44 PM Tom_L: sdp-si
06:44 PM Tom_L: they had the ratios & sizes i wanted
06:45 PM roycroft: i'll check there
06:45 PM roycroft: i got the gears for my mill from b&b, and i'm happy with them
06:45 PM Tom_L: 15mm wide GT2 5mm
06:45 PM roycroft: that's the only place i've checked so far for this build
06:45 PM Tom_L: GT has a more rounded profile than X XL etc
06:45 PM roycroft: and they did not have exactly what i wanted, but they had close enough to work
06:46 PM Tom_L: GT3 is best but i couldn't find much in them yet. i think they were fairly new
06:46 PM Tom_L: i got belts & pullies for a 2:1 and 3:1 setup
06:49 PM roycroft: actually, making an adapter might work out a lot better
06:49 PM roycroft: the shaft on my motor is 10mm in diameter, and most of the smaller gears have a 6mm bore
06:50 PM roycroft: i was planning on boring out to 10mm, but if i make an adapter to extend the shaft i can make the shaft part 6mm
06:52 PM roycroft: sdp-si's prices are pretty good
06:52 PM unterhausen: I'm glad I watched a youtube about cnc'ing a lathe. The person used a timing gear setup that gave him 2 indexes per rev
06:53 PM roycroft: 4 week lead time, though
06:53 PM unterhausen: turns out it's not a great idea
06:53 PM unterhausen: my lathe came with a tach on the spindle. Little tiny tach, great big timing gear
06:53 PM roycroft: i could live with that lead time, as long as it's not extended beyond that
06:54 PM roycroft: i have errands to run and dinner with friends, so i'm out for a while
06:54 PM roycroft: thanks, tom_l
07:02 PM unterhausen: should I expect my 3d printer to take an hour and a half to print a base for an arduino uno?
07:09 PM Tom_L: i tried to work with ones they had in stock
07:46 PM unterhausen: roycroft has to come back and tell me if opera-mini.net is a vpn
07:49 PM unterhausen: i see, it's a pre-processor for opera. Many servers running chrome and then they take a screen shot
08:03 PM _unreal_: so freaking upsetting. got my board and cut down. but its RAINING really hard out. I cant bring the board in
08:03 PM _unreal_: :(
08:20 PM * t4nk_freenode comforts _unreal_ with a hot beverage
08:20 PM t4nk_freenode: use a coaster though! :b
08:20 PM t4nk_freenode: look man... I'm starting to get rather annoyed with this backlash thing
08:20 PM t4nk_freenode: can't seem to get a grasp on it
08:21 PM t4nk_freenode: I think in my case there might be a difference in backlash, depending on the direction
08:22 PM t4nk_freenode: now I'm tempted to redesign the other bearings too... using skateboard bearings after all
08:23 PM t4nk_freenode: it's gonna be very tight, and I may need to perform some magic to be able to make some semi-drop-in replacements
09:26 PM _unreal_: is your slack in the lead screw or in the rails?
09:26 PM _unreal_: generally you get backlash from your lead screw or play in the rails. more so the rails.
09:27 PM _unreal_: again its the reason why I went threaded rod
09:27 PM _unreal_: I'd rather ballscrew but I dont have the $ for that as well
09:30 PM t4nk_freenode: nah, remember how I recently modified the bearings on my z-axis?
09:31 PM _unreal_: yes
09:31 PM t4nk_freenode: putting bearings in there improved things a lot, now there's no backlash at all, so the anti-backlash nut can do its work
09:32 PM _unreal_: so you had a lot of resistance
09:32 PM t4nk_freenode: if anything, I think that the bearings/bushings on the other rails are causing the issues
09:32 PM t4nk_freenode: yeah
09:32 PM _unreal_: gee... could of swarn I said something about that months ago
09:32 PM t4nk_freenode: it seems like it's a bit unpredictable
09:34 PM t4nk_freenode: but I don't understand why it was 'fine' before
09:34 PM _unreal_: I TOLD YOU it will wear out
09:34 PM t4nk_freenode: no, no, and no again
09:34 PM t4nk_freenode: it's not from wear
09:34 PM _unreal_: its just thin 3d printed plastic sliding on metal
09:36 PM t4nk_freenode: if only I had chosen a regular size tubing.. 15mm I don't think there are linear bearings for those
09:41 PM t4nk_freenode: I'll start designing some new bearings tomorrow, print one, and see how it goes
09:44 PM t4nk_freenode: but I'll have to make some slots into the sideboards, I don't feel like milling new ones
09:44 PM t4nk_freenode: and I don't have many m8 nuts and bolts leftr
09:45 PM t4nk_freenode: heh, so I'll be cutting threaded rod into pieces
09:45 PM t4nk_freenode: :b
09:45 PM _unreal_: I do that a lot
09:46 PM t4nk_freenode: pffff... but apart from that; I'll be ordering some of that c beam very soon, perhaps next week
09:46 PM _unreal_: really helps if you have a bench grinder/wire wheel
09:46 PM t4nk_freenode: yeah, lol, I recently put a little diamond disc into the er-11 to cut some m3 nuts
09:47 PM t4nk_freenode: I'll put it into my regular drill to cut the rods
09:47 PM t4nk_freenode: I'm thinking of ordering 3x1m 4080 c beam
09:47 PM t4nk_freenode: and then 250mm for the z-axis
09:50 PM t4nk_freenode: bunch of wheels
09:53 PM t4nk_freenode: but I'm not sure if 1m will be too big
09:53 PM t4nk_freenode: it sure would be nice though
10:11 PM t4nk_freenode: what would you do if you put 3 bearings on the y rail; two on top, one on the bottom, or one on top and two on the bottom?
10:13 PM t4nk_freenode: I think one on top
10:13 PM _unreal_: does not matter
10:13 PM _unreal_: because when you reverse direction the load directions change
10:15 PM t4nk_freenode: not really I'd say
10:15 PM t4nk_freenode: most of the load would be from everything hanging down
10:16 PM Tom_L: so you think
10:16 PM t4nk_freenode: I think a lot ;)
10:17 PM t4nk_freenode: one on top would mean that the load is smack in the middle, but it would also mean more wear
10:21 PM t4nk_freenode: lol.. seems like I'll have to mix it up anyhow; thanks to my brilliant design. :|
10:26 PM _unreal_: so tired bed time
10:39 PM perry_j1987: hows it going
