07:55 AM JT-Cave: 设置视口
10:05 AM JT-Shop: step 1 light a fire
10:10 AM lcnc-relay: <travis_farmer (@_discord_731083529441640538:jauriarts.org)> this hurts... i was prescribed Penicillin V Potassium for a swollen lymph node... since starting it yesterday, now my joints all seem to hurt, a lot. called the ER, and they said nothing to worry abou
10:10 AM lcnc-relay: <travis_farmer (@_discord_731083529441640538:jauriarts.org)> t... not sure if i trust them or not...
10:13 AM JT-Woodshop: step 2 light another fire
10:14 AM Tom_L: or stay in one spot
10:15 AM JT-Shop: https://medlineplus.gov/druginfo/meds/a685015.html
10:16 AM JT-Shop: Some side effects can be serious. If you experience any of these symptoms, call your doctor immediately or get emergency medical treatment: joint pain
10:16 AM lcnc-relay: <travis_farmer (@_discord_731083529441640538:jauriarts.org)> like i said, i called the er, they said nothing to worry about...
10:17 AM Tom_L: does the ER have your medical history?
10:17 AM Tom_L: likely only your regular doctor does
10:17 AM lcnc-relay: <travis_farmer (@_discord_731083529441640538:jauriarts.org)> they should. same hostpital
10:18 AM lcnc-relay: <travis_farmer (@_discord_731083529441640538:jauriarts.org)> all shared through My Chart
10:19 AM lcnc-relay: <travis_farmer (@_discord_731083529441640538:jauriarts.org)> they just said to keep taking the penicillin and consult my PCP on tuesday
10:28 AM lcnc-relay: <travis_farmer (@_discord_731083529441640538:jauriarts.org)> Hmmm, Dr mom, and google... along with my tremors, balance/stability issues, tiredness, and now joint pain... both Dr mom and google are suggesting MS... i wish neurology would make my referral appoin
10:28 AM lcnc-relay: <travis_farmer (@_discord_731083529441640538:jauriarts.org)> tment, because Dr google is not helping my mental health much...
11:52 AM Unterhaus_ is now known as Unterhausen
12:20 PM Unterhausen: I decided I needed to get more organized, so I bought a large number of organizer bins. Now my organizer bins need to be organized
12:24 PM Tom_L: bins are excuses to have more stuff
12:39 PM Roguish: Tom_L, all flat surfaces are tooo
12:41 PM roycroft: the royal society for putting things on top of other things can help you get that sorted, roguish
12:42 PM roycroft: https://www.youtube.com/watch?v=LFrdqQZ8FFc
12:49 PM Roguish: I was hoping to get a major purge done this past summer. but failed miserably.... this coming summer for sure.
12:50 PM Tom_L: a resolution you plan to keep?
12:50 PM Tom_L: :)
12:50 PM Roguish: sure hope so.
12:50 PM Roguish: got way to much shit
12:52 PM Tom_L: when did it turn to shit? because when you got it, it certainly wasn't :)
12:52 PM Tom_L: i could probably fill a dumpster and not miss most of it too
12:55 PM Unterhausen: the thing that kicked this off is I found my outlandish collection of XLR connectors, but couldn't find the outlandish collection of 1/4" jacks. Annoying
12:56 PM Unterhausen: Some of the stuff I have was definitely junk when I bought it, I used to live in an area with a lot of electronic surplus stores
12:56 PM Unterhausen: "How much for that?" "$25, but you have to take it all"
12:57 PM Tom_L: so you did
01:09 PM Unterhausen: bargain
01:10 PM Unterhausen: I was looking for an apparently obscure electronic part. I thought aliexpress would have it, but no results from there
01:24 PM jfsimon1981: Good evening, are there a couple good quality recommended cnc stepper boards, i think the TB6560 which was manufactured long ago isn't widely available now.
01:24 PM jfsimon1981 is now known as jfsimon
01:25 PM jfsimon: I mean the parallel port stepper board for 24/36V 2.5/3.5A. 3 or 4 axis.
01:29 PM Tom_L: the glue gun croud would know all about those
01:30 PM XXCoder: I used tb6560, it wasnt too great, so I ued 3 seperate tb6600 boards and it was great. dunno if its still being sold
01:30 PM XXCoder: Tom_L: nah 3d printers dont use tb6560 (nor tb6600)
01:32 PM XXCoder: as on more current ones, I dont know as my knowledge is bit obselete
01:36 PM Unterhausen: Remora people might have a better idea
01:37 PM XXCoder: or project millenium mill, as they use small scale mill. or capt might have ideas.
01:46 PM Unterhausen: Cap'n probably get stuck talking about glue guns and forget about stepper drivers
01:47 PM Unterhausen: Some of the driver chips are apparently really good now, but they all are required to have essentially the same part number. So who can keep track
01:51 PM Tom_L: solarwind posted a link to one he likes now
01:59 PM lcnc-relay: <big_kevin420> i mostly use these
01:59 PM lcnc-relay: <big_kevin420> https://www.pololu.com/product/2133
01:59 PM lcnc-relay: <big_kevin420> https://www.pololu.com/product/1182
01:59 PM jfsimon: Thanks XXCoder, i'm almost thinking if i shouldn't develop the board
02:00 PM _unreal_: I'm trying to find a motherboard likely PC104 that supports this AP-FC0128M0N5M-2T
02:00 PM jfsimon: i had the red TB6560 but it burned channels, i huess the quality it's too perfect, in fact on short circuit it can burnt pretty strong.
02:00 PM _unreal_: AP-FC0128M0N5M-2T = 128meg DICKCHIP
02:00 PM XXCoder: if I recall right, drv8825 has problems
02:01 PM _unreal_: drv8825 is very senstive to what is powered first
02:02 PM lcnc-relay: <big_kevin420> idk, i buy 10 for $10 , think ive only burned 2 in 1 years
02:02 PM lcnc-relay: <big_kevin420> 10 years
02:02 PM XXCoder: theres chips specifically designed to smooth out output from drv
02:02 PM lcnc-relay: <big_kevin420> then for parra i connect it like these guys on the v1 forum
02:02 PM lcnc-relay: <big_kevin420> https://us1.dh-cdn.net/uploads/db5587/optimized/3X/e/5/e545ad1f9dac6d4b8c139b5d4c24515803a13461_2_666x500.jpeg
02:03 PM lcnc-relay: <big_kevin420> the tmc2209 is fine too
02:13 PM solarwind: TMC2209 is the one to use for open loop small steppers
02:13 PM solarwind: TMC5160 with external MOSFETs for larger
02:13 PM solarwind: bigtreetech sells them both in ready to use modules for pocket change
02:15 PM solarwind: out of all the drivers I've analyzed, these output a "good signal" as described in their white papers (I verified with my oscilloscope)
02:15 PM solarwind: Don't bother with any other drive for open loop control. TMC5160 can also take encoder feedback
02:48 PM jfsimon: Thanks lcnc-relay
02:50 PM XXCoder: you mean big kervin ;)
03:03 PM JT-Shop: or maybe big_kevin420 even
03:18 PM solarwind: The real hero, lcnc-relay
03:19 PM solarwind: tell me, would kevin be able to talk to us at all without lcnc-relay?
03:19 PM solarwind: I think not
03:24 PM solarwind: **M* inserts are so pointless for hobby use. Molded just leaves crappy surface finish. I could just as well use M2 steel.
03:25 PM solarwind: **G* cermet inserts are fantastic, night and day difference in surface finish. The sharp edge and self sharpening action lets you get very tight tolerances
03:26 PM solarwind: And they have a ground edge without a large land, allowing you to do less than 50µm depth of cut
03:29 PM solarwind: https://www.aliexpress.com/item/1005005376976915.html A+
03:45 PM Tom_L: solarwind, get some ceramic inserts
03:48 PM JT-Shop: I've never used a ceramic insert
03:49 PM Tom_L: me either but i know shops around here use some
03:50 PM Tom_L: for tough metals
03:50 PM * JT-Shop goes to glue another bit on the steam box
03:51 PM Tom_L: they don't like interrupted cuts
03:51 PM Tom_L: but give a good surface finish
03:52 PM Tom_L: i'd imagine mostly for turning operations
03:52 PM JT-Woodshop: hmm warm in here
03:52 PM Tom_L: i've been chilly all day
03:53 PM Tom_L: even though the temp inside is the same
03:53 PM JT-Woodshop: 70°F in here
03:53 PM JT-Woodshop: 40°F outside
03:55 PM Tom_L: i don't think it got above freezing here
03:55 PM Tom_L: if it did it wasn't by much
03:56 PM Tom_L: was gonna piddle in the shop but don't think i'll heat it up now
03:59 PM Tom_L: i needed some 5/16 dowel pins for the project and found i don't have any so i'll put it off til the shops reopen
04:00 PM Tom_L: i _could_ use 1/4"
04:00 PM JT-Shop: what kind of dowel pins?
04:00 PM JT-Shop: I have a lot of dowel pins...
04:01 PM Tom_L: steel
04:01 PM Tom_L: like for aligning press dies etc
04:01 PM JT-Shop: ground or split?
04:01 PM Tom_L: ground
04:01 PM JT-Shop: ground then
04:02 PM Tom_L: my local guy has a good supply but i'll have to wait
04:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Spring_mod7.jpg
04:03 PM Tom_L: figuring a way to make one of those 2 types of springs with the cnc
04:04 PM Tom_L: he's using the coil right now but i think the V would work for his project and be simpler to make
04:04 PM Tom_L: not that much bend on it i think
04:04 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Spring_mod6.jpg
04:04 PM Tom_L: just a quick mockup
04:06 PM JT-Woodshop: I have a box of 5/16" x 3/4" maybe 98 ofthem
04:06 PM Tom_L: and with it inside, it gets it more out of the way
04:06 PM Tom_L: i'm gonna get some 1 & 2" ones i think
04:06 PM Tom_L: they're not that much
04:07 PM Tom_L: for my little mill, i'm usually using smaller ones
04:07 PM Tom_L: .250 would probably work
04:08 PM Tom_L: except for the mandrel to hold the coil
04:08 PM JT-Shop: I have some 5/16" x 1" but when I opened the box they are rusty so in the scrap bin they go
04:08 PM Tom_L: i suppose even that could be wound smaller
04:09 PM Tom_L: lots of dies get made here for stamping sheetaluminum for aircraft so there's an abundance of them around
04:09 PM JT-Shop: hmm I need to take an inventory
04:09 PM Tom_L: early on i made a few for my bud using old mylar prints
04:10 PM Tom_L: i think mylar prints have all but disappeared here
04:11 PM JT-Shop: finally got the deer to come back up here to eat but mom is walking around kinda nervous
04:12 PM roycroft: i have the broken screws extracted, so progress
04:12 PM roycroft: i need to figure out what, if any, hardware and supplies i might need tomorrow, as nothing will be open
04:12 PM Tom_L: screw extractors
04:12 PM Tom_L: easyouts
04:13 PM roycroft: easyouts don't work well with #8 screws in wood
04:13 PM Tom_L: no probably not
04:14 PM roycroft: i used a hardened annular cutter that runs in reverse
04:14 PM roycroft: the kind everyone complains about
04:14 PM roycroft: because they are made for and marketed to woodworkers who don't know how to use them, so they break them
04:15 PM roycroft: https://www.woodcraft.com/products/screw-extractor-5-16
04:15 PM roycroft: it actually works really well
04:16 PM roycroft: i used it in the milling machine, though, which was a real help because i could easily center it over the broken screw
04:16 PM roycroft: one problem many folks have is they don't center it properly and they break it when it hits the screw
04:17 PM JT-Shop: looks like one of my hens will die tonight
04:17 PM roycroft: i think the main problem is that they insert it in the drill press chuck and then tighten the crap out of the chuck jaws until the tool shatters
04:17 PM roycroft: sorry to hear that, jt-shop
04:17 PM roycroft: dealing with a dead animal is not a good way to start the new year
04:18 PM JT-Shop: thanks, trying to keep her comfortable is about all I can do
04:18 PM Tom_L: yeah, sorry to hear that
04:19 PM JT-Shop: next warm spell I'll move the remaining two from coop deux to coop uno
04:19 PM Tom_L: roycroft, i've got a similar tool for clearing glue from dowel holes
04:20 PM roycroft: i bet the screw extractor would do a good job with that
04:20 PM Tom_L: only not reverse cut
04:20 PM roycroft: yeah, you don't need reverse cut for that
04:20 PM roycroft: i was pretty impressed with that extractor
04:21 PM roycroft: and the holes it bored were nominally 5/16", but when i plugged the holes with 5/16" dowels i had to pound them in - it was definitely a slight interference fit
04:21 PM Tom_L: do you plug the hole then or go back with something bigger?
04:22 PM roycroft: i plugged with dowels
04:22 PM roycroft: when the glue sets i'll trim them and redrill for #8 screws
04:22 PM Tom_L: i've done that with 1" dowels in the past for large 'messes'
04:22 PM solarwind: Tom_L cermet is similar to ceramic, but has a metal binder to increase toughness
04:22 PM solarwind: it's very suitable for mild steel
04:22 PM roycroft: since they'll be going into dowels it will be screwing into end grain, but that won't be an issue at all
04:23 PM solarwind: I have CBN inserts, they're even harder, but the surface finish isn't nearly as good
04:23 PM roycroft: there will be virtually no tension in the screws, no shear forces, and barely any compression force
04:24 PM roycroft: anyway, i hadn't used that kind of extractor before - it's really great
04:24 PM roycroft: i don't think i'd want to use it in a hand-held drill, though, so it's only useful for things that can fit on the drill press/milling machine table
04:26 PM roycroft: i do have a drill guide block, but it doesn't position the drill as well as a drill press, and as hard as those cutters are, i'm not sure i'd trust it to work
04:30 PM Tom_L: maybe handheld with a guide
04:32 PM lcnc-relay: <big_kevin420> @solarwind they cant really do closed loop exactly. not with linuxcnc anyways
04:32 PM roycroft: the best thing is to not break off screws in wood
04:32 PM lcnc-relay: <big_kevin420> uses some internal tp ramp proifile stuff, no one interfaces it
04:32 PM roycroft: and that can best be accomplished by not using screws made of chinese mystery metal
04:33 PM lcnc-relay: <big_kevin420> " tell me, would kevin be able to talk to us at all without lcnc-relay?"
04:33 PM lcnc-relay: <big_kevin420> you could, but my name would be different
04:45 PM lcnc-relay: <_veegee#0> big_kevin420 (@_discord_848368676289773618:jauriarts.org) lol I'll just use discord to tag you, it's easier
04:46 PM lcnc-relay: <_veegee#0> But anyway, I had this confusion a long time ago about where it's important to "close the loop"
04:47 PM lcnc-relay: <_veegee#0> As far as LinuxCNC goes, it doesn't need to close the loop at the motion planner. Ideally, the motion planner just gives the actuators commands on where to be at any given time and not worry about it
04:47 PM lcnc-relay: <_veegee#0> at all. LinuxCNC can simply assume they are where they're supposed to be at all times.
04:48 PM lcnc-relay: <_veegee#0> So you only need to close the loop in the servo drive. If using closed loop steppers, or TMC5160 drives, you will know if missed steps occur and will be able to correct for them automatically in the d
04:48 PM lcnc-relay: <_veegee#0> rive.
04:49 PM lcnc-relay: <_veegee#0> So it technically is "closed loop" just as much as any other traditional topology. I actually like it better like this for most applications.
04:53 PM lcnc-relay: <_veegee#0> Especially when timings like step generation are so critical. I'd much rather have dedicated hardware like an FPGA or perhaps TMC5160 in one of its positioning modes handle all of that. Software just
04:53 PM lcnc-relay: <_veegee#0> cannot and should not do that, especially when multi axis synchronization is required.
04:55 PM lcnc-relay: <_veegee#0> It's extremely difficult to get cycle-by-cycle accuracy with anything fancier than an 8 bit µC because of how the CPU/cache/memory/instructions are not synchronized how you expect. A fast CPU like a d
04:55 PM lcnc-relay: <_veegee#0> esktop computer doing the high level motion planning and offloading actual servo control to some kind of dedicated hardware or servo drive is the best solution.
04:57 PM lcnc-relay: <_veegee#0> That's why I love the modern ethercat drives so much, with their multi axis synchronous position mode. They really are fire and forget and well worth the asking price. I just cannot get them to fail o
04:57 PM lcnc-relay: <_veegee#0> r fool them even when powered off (leadshine EC7 series with battery backed encoders).
04:57 PM lcnc-relay: <_veegee#0> LinuxCNC just tells them to go somewhere and they do it perfectly 100% of the time.
05:06 PM Loetmichel: happy new year from germany!
05:08 PM * JT-Shop wonders if Nails will make to next year or not
05:09 PM XXCoder: less than day left, so probably?
05:10 PM JT-Shop: it's hard to say but I'm keeping her comfortable until she ends
05:11 PM XXCoder: yeah all we can do sometimes. keeping comfortable as best as can
05:11 PM JT-Shop: yup
05:14 PM JT-Shop: you make a commitment to them to protect and keep the safe when you get the chicks
05:14 PM JT-Shop: some don't...
05:14 PM XXCoder: yup. I hate how some gets rabbits for easter
05:15 PM XXCoder: so many of them die in less than year, because rabbits dont just eat carrot
05:15 PM XXCoder: and they can live over 10 years
05:15 PM JT-Shop: we have a few wild rabbits that I support
05:16 PM Loetmichel: XXCoder: IIRC carrots are actually bad for them in excess
05:16 PM XXCoder: yeah
05:16 PM JT-Shop: my neighbor has a rabbit and she would come and eat carrots with me
05:19 PM JT-Shop: had
05:19 PM solarwind: https://www.kijiji.ca/v-view-details.html?adId=1671241101 how can you beat a deal like that
05:20 PM solarwind: $15 for 1"-2" starrett micrometer
05:21 PM Unterhausen: I have an old micrometer that would be very convenient, but it's too hard to read the Vernier
05:21 PM Unterhausen: don't hold the thing by the scale, granpa
05:22 PM JT-Shop: say goodnight Gracie
05:24 PM pcw-home: Goodnight Gracie (one of our inherited bottle baby sheep is named Gracie and we don't say goodnight Gracie but do say "Out Gracie!" a lot)
05:25 PM JT-Shop: lol
05:26 PM JT-Shop: see you guys next year
05:29 PM XXCoder: yep
05:30 PM XXCoder: lol https://youtu.be/JnsrR6ZwnNg use loop feature for this videp
05:54 PM solarwind: Found a way to make solder paste with 56% silver solder - file it with a coarse file and mix it into the flux :P
05:55 PM solarwind: works really well for getting it into very tight/inaccessible places and making sure only a small amount is used
05:56 PM solarwind: might try mixing it with copper powder too to increase thermal conductivity
06:01 PM roycroft: copper is less thermally conductive than silver
06:02 PM solarwind: but it's significantly more thermally conductive than a 56% silver alloy
06:02 PM Loetmichel: hmm, i never had a 56% silver alloy solder for electronics
06:02 PM solarwind: even small amounts of impurities in copper significantly decrease its electrical and thermal conductivity
06:02 PM roycroft: diamond, however is more than twice as thermally conductive than silver
06:02 PM solarwind: Loetmichel it's not for electronics, it's for brazing
06:02 PM Loetmichel: the ones i know are more like Sn96Ag3Cu1 or so
06:02 PM Loetmichel: ah
06:03 PM Loetmichel: i see, that makes sense
06:03 PM Loetmichel: THERE i know high silver alloys
06:03 PM solarwind: harris stay silv 45 and 56
06:03 PM solarwind: I use it a lot for brazing tungsten carbide to steel
06:04 PM Loetmichel: i just saw "solder paste" and assumed "smt electronics"
06:04 PM Loetmichel: my bad
06:04 PM XXCoder: I look forward to my dinner today
06:04 PM solarwind: It's expensive but you only need very little when you do need it
06:04 PM XXCoder: winco sushi
06:05 PM Loetmichel: hmm, considering that i see my TC mill bits light up red sometimes i wouldnt be comfortable if they had silver solder brazed on plates :)
06:05 PM solarwind: if your carbide is getting that hot, it's probably not lasting that long
06:06 PM solarwind: I've never heard of a joint failure in brazed carbide tools
06:06 PM Loetmichel: yeah, well, 1/8" shaft mill bits. They are more or less "throw away"
06:06 PM solarwind: well "throw away" in my direction will ya?
06:06 PM Loetmichel: at 24kRPM you sometimes get them "a bit hot"
06:07 PM solarwind: I make my own brazed carbide tools extensively
06:07 PM Loetmichel: i meant: they are more or less one time use. If they are dull or broken you just get a new one, no regrinding or repairing
06:07 PM solarwind: lol! I know
06:08 PM solarwind: I meant when they get dull, throw them in my direction
06:08 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=12979&g2_imageViewsIndex=1
06:08 PM Loetmichel: that kind
06:08 PM Loetmichel: I DO use them until they are dull though
06:09 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17709&g2_imageViewsIndex=1 <- evem made a "temporary storage" for used ones
06:09 PM solarwind: Why the insanely high surface speed though? It should be half that
06:09 PM Loetmichel: because the spindle has no torque
06:09 PM solarwind: Even with exotic coatings, that's really high for a 3.2mm end mill
06:09 PM Loetmichel: especially at lower RPM
06:10 PM Loetmichel: those are 2mm two flute endmills, only the shaft is 3.175mm
06:11 PM Loetmichel: the latter pic is one of the two 6040 at the company btw.
06:11 PM solarwind: that's 1,500mm/min (!!!)
06:12 PM solarwind: that's well beyond what even the most high end carbide tools should be run at
06:12 PM solarwind: that's beyond what ceramic should be run at lol
06:13 PM Loetmichel: as i said: those 800W spindles have next to now torque at lower RPM
06:13 PM Loetmichel: they tend to stall with a 3.175mm two flute in alu at 8krpm
06:13 PM solarwind: sorry 250m/min
06:13 PM Loetmichel: believe me i tried.
06:13 PM solarwind: oh for aluminum it's fine
06:14 PM solarwind: my bad miscalculated, 250m/min surface speed is very high for steel, but totally fine for aluminum
06:15 PM Loetmichel: its a bit scary to use the 35mm facing bit to face off the Pertinax vacuum table at 24k though (same reason) especially because its only meant for 8k
06:15 PM solarwind: Is it a DC spindle?
06:15 PM Loetmichel: three phase
06:15 PM solarwind: well it should be fine
06:15 PM Loetmichel: water cooled
06:15 PM solarwind: 3 phase induction motors are constant torque machines
06:16 PM Loetmichel: obviously not in this case (or at least with the chinese preset parameters in the VFD)
06:16 PM solarwind: they have the same torque throughout their RPM range
06:16 PM solarwind: Yeah adjust the VFD
06:16 PM Loetmichel: no manual (that i can read)
06:16 PM solarwind: I bet I can find one if you want
06:17 PM solarwind: I have a similar setup, but 3kW spindle
06:17 PM solarwind: water cooled makes it less critical to run at high speed since you don't need to worry about a fan pushing air through it
06:17 PM Loetmichel: nah, for the moment both machines are "waiting for maintenance/repairs" anyway
06:17 PM Loetmichel: last 80h job killed one driver box and on the one in the picture it lost half the balls from the linear rails
06:18 PM solarwind: try cermet end mills
06:19 PM solarwind: they're well suited to those speeds
06:19 PM Loetmichel: already ordered new SBR sleds and thinking about reinforcing/modding the gantry to SBR, too
06:19 PM solarwind: Try these: https://www.aliexpress.com/item/1005004975725142.html
06:19 PM solarwind: BB tools is reputable
06:20 PM Loetmichel: that was REALLY annoying to only use 0,3mm DOC on the 6mm endmill to remove 90% of a 20mm thick slab for a Notebook enclosure TWICE
06:20 PM Loetmichel: as i said: 80h++
06:20 PM XXCoder: couldnt you use those slab flattening tool to cut bulk of it off?
06:20 PM Loetmichel: and all because the gantry is so weak that it starts to flutter at higher DOC
06:21 PM XXCoder: ie you first make spot for tool to get into, then change tool to flattening one
06:21 PM lcnc-relay: <zincboy_ca_on> I like the BB tools endmills. I have been buying a bunch of them for things like theadmills, backside chamfer, tslot, and lollypop
06:21 PM Loetmichel: that said: its surprising that those cheapo engraving machines did 10+ years of semi-industrial use before starting to fail
06:21 PM solarwind: Deskar is also reputable, they're the manufacturer. I buy inserts directly from them
06:22 PM XXCoder: yeah and I bet it would just need minor rebuold to work well again
06:22 PM XXCoder: what is failing anyway
06:22 PM Loetmichel: as i said: the SBR sleds on the x lost balls
06:22 PM Loetmichel: and tons of them, not one or two
06:23 PM solarwind: replace that shit with HGR rails
06:23 PM XXCoder: interesting. sounds like fairly simple fix yeah
06:23 PM XXCoder: or yeah rebuld to use some good MGN
06:23 PM solarwind: HGR >>> MGN
06:23 PM Loetmichel: solarwind: that would be overkill
06:23 PM Loetmichel: new sleds is ok if it lasts another 10 years ;)
06:23 PM XXCoder: yeah I guessed it would be overkill
06:23 PM solarwind: but it's a lot more rigid
06:23 PM solarwind: and not that expensive
06:24 PM Loetmichel: its only more rigid if the HGRs have something to bolt onto thats rigid
06:24 PM solarwind: the rails themselves are very thick
06:24 PM solarwind: they're not like MGN rails
06:24 PM solarwind: they're thick, hardened steel
06:27 PM Loetmichel: as i said: ANY kind of linear rails are meant to bolt to something rigid. they themselves are not. As seen on the gantry where they used standard unsupported rails with the afromentioned tendency to limit ones DOC because of springing
06:28 PM Loetmichel: To be honest: i tortured those machines for a decade. They are meant for light engraving in wood and plastics. Not 10+ years of heavy work in alu and brass
06:29 PM Loetmichel: its a wonder they even lasted as long as they did
06:29 PM Loetmichel: but you make do with the tools you can pull out of your cheap bosses nose.
06:30 PM Loetmichel: maybe now that we are bought by a big international company i have a chance to "upgrade" the toos a bit ;)
06:30 PM Loetmichel: tools
06:32 PM solarwind: oh
06:32 PM solarwind: I thought it was a hobby machine
06:32 PM solarwind: if that's what your cheap ass company provides, that's... very sad
06:33 PM Loetmichel: indeed
06:38 PM XXCoder: yeah its been shocking how cheap company loet works at across years
06:45 PM Loetmichel: well, to dampen the "cheapness" those two machines were for prototype-work. The series stuff was always subcontracted out.
06:45 PM Loetmichel: and ARE for protyping
06:45 PM Unterhausen: the chip I'm looking for seems to be widely used in products, but all 6 options at mouser and digikey are order only
06:50 PM Unterhausen: of course, a giant reel of them would be tiny, just my wife wouldn't approve of the expense
07:14 PM roycroft: my guests will be arriving shortly, so i'll be afk for the rest of the evening
07:14 PM roycroft: i want to wish you all a happy and prosperous new year
07:23 PM Unterhausen: I'm celebrating by not doing duolingo tonight
07:26 PM Unterhausen: the fact I can't find my phone is helping
07:42 PM CaptHindsight: Solarwind: https://www.youtube.com/watch?v=dNxaCQaCaGY and you thought machining was action packed
07:44 PM XXCoder: till now, I never knew tere was tag pros
07:44 PM CaptHindsight: you're it!
07:44 PM * XXCoder lets timer expires
08:23 PM CaptHindsight: xxcocer: I got tired just watching this https://www.youtube.com/watch?v=rnO59tizy6E
08:24 PM XXCoder: that reminds me, I want to buy 3 wheeled bicycle soonish
08:26 PM XXCoder: beautful vistas though
08:26 PM XXCoder: some of track areas is roufg
08:26 PM XXCoder: rough
08:29 PM XXCoder: wow it gets dangerous
08:29 PM XXCoder: 4:50
08:32 PM XXCoder: uphill section'd have murdered me 10 times
08:33 PM CaptHindsight: near the end he dodging trees at the same speeds
08:36 PM XXCoder: nice thin bridge
08:36 PM XXCoder: #2 bridge
08:41 PM XXCoder: whoa. actual roads!
08:43 PM XXCoder: ended the roads run lol
08:43 PM XXCoder: I see the trees now. wow
08:44 PM XXCoder: i had biccycled though trees area, but never at high speeds
08:44 PM XXCoder: or high danger
08:47 PM XXCoder: thin bridge is dangerous, thin bridge with side walls somehow more dangerous
09:35 PM XXCoder: lol very foggy here
09:35 PM XXCoder: ruins fun for people trying to use illegal fireworks
09:46 PM Unterhausen: little dog would approve of people not being able to enjoy fireworks
09:47 PM Unterhausen: and pour one out for hand surgeons, who always have to work NYE
09:47 PM Tom_L: one of mine hated fireworks
09:48 PM XXCoder: im been careful with fireworks, because I rather waste a firework than waste my hand
09:57 PM XXCoder: Tom_L: interesting video
10:03 PM Tom_L: it can run alot faster but i was testing
