02:21 AM Deejay: moin
05:14 AM JT-Cave: morning
05:24 AM Tom_L: morning
07:46 AM JT-Cave: debian 11 mate termial sucks
08:12 AM JT-Cave: fixed the terminal
09:20 AM Tom_L: what sucks about it?
09:20 AM Tom_L: it's a terminal..
09:21 AM JT-Cave: if you highlight a line to the end and click the middle mouse button it highlights the line and puts the cursor on the next line, before it would execute the command
09:21 AM Tom_L: ahh
09:21 AM JT-Cave: # fix paste newline
09:21 AM JT-Cave: if [[ $- == *i* ]]; then
09:21 AM JT-Cave: bind 'set enable-bracketed-paste off'
09:21 AM JT-Cave: fi
09:22 AM JT-Cave: put that in .bashrc and it restores the correct behavior
09:22 AM Tom_L: you should add that to your next 'install' page :)
09:23 AM Tom_L: i used to like mate
09:23 AM JT-Cave: debian 10 it worked fine...
09:25 AM Tom_L: well, i think i've collected all the parts for a bathroom remodel now
09:25 AM JT-Cave: that sounds like fun...
09:25 AM Tom_L: just got back from ~50 mile trip to get a part nobody had here
09:25 AM Tom_L: it will be a 'teaching' experience for the boys
09:26 AM Tom_L: 2x as long :)
09:26 AM JT-Cave: I'm still cleaning and organizing the garage then down here is a disaster
09:28 AM JT-Cave: remodeling is 4 times harder than building new
09:28 AM Tom_L: may have to bust out some concrete for the drain
09:28 AM Tom_L: the tub drain was smaller than just a shower drain
09:29 AM Tom_L: they wanted just a shower this time in the basement
09:29 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/house/10.jpg
09:30 AM JT-Cave: same here when I took the jacazzi out and put a walk in shower the drain was in a different location and larger
09:30 AM Tom_L: i was actually looking at that to see if i could figure out what size pipe they ran to it ther
09:30 AM Tom_L: e
09:30 AM JT-Cave: looks like fun
09:30 AM Tom_L: that's covered in concrete now
09:31 AM Tom_L: all but the end run of the tub drain
09:31 AM Tom_L: which may need to be enlarged a bit
09:31 AM Tom_L: i think it's 2" so i should be ok i hope
09:34 AM Tom_L: i think the plumbers could have taken a more direct approach there but i think they were selling pipe
09:41 AM unterhausen: can I put foam insulation around surface mounted conduit
09:41 AM unterhausen: google thinks I don't actually want to know the answer to this question
10:19 AM -!- #linuxcnc mode set to +v by ChanServ
11:25 AM roguish[m]: unterhausen: you can, question is whether or not it's within code.....
11:26 AM roguish[m]: unterhausen: other questions are: is it safe, and will it ever be seen by a building inspector
11:29 AM unterhausen: it won't be seen because it's buried :)
11:29 AM unterhausen: I like to do things my code, that's what I'm trying to figure out
11:30 AM unterhausen: I guess I could detach it and surface mount it on the new wall
11:31 AM unterhausen: insulation companies suggest using conduit in spray foam applications. Not sure I trust them
11:33 AM roycroft: would be the reason for insulating the conduit?
11:33 AM roycroft: what would, rather
11:37 AM unterhausen: It's on a bare concrete block basement wall
11:38 AM unterhausen: It has come to my attention that there is plenty of heat going through that wall
11:52 AM satiowadahc[m]: This is the time you can justify a fancy thermal camera to see the difference
11:54 AM JT-Shop: conduit is buried in all sorts of materials including concrete!
12:02 PM roycroft: i am confused
12:02 PM roycroft: but i'm just starting to drink my cappuccino
12:03 PM roycroft: i thought we were talking about insulating buried conduit
12:03 PM roycroft: but it looks like we're talking about insulating surface mounted conduit
12:06 PM Tom_L: or just conduit
12:06 PM Tom_L: or just insulation?
12:06 PM unterhausen: burying conduit in concrete is less problematic since it conducts heat pretty well
12:06 PM Tom_L: but
12:06 PM Tom_L: if you're gonna do that make sure it's at least 2x bigger than you need now
12:07 PM Tom_L: i ran 2 2" out to the garage
12:07 PM Tom_L: never been sad about it
12:11 PM unterhausen: the conduit is there, I just want to insulate over top of it
12:11 PM unterhausen: yeah, I wish it was bigger
12:12 PM unterhausen: I suppose the easiest way is to just tear it out and replace it
12:54 PM seb_kuzm1nsky is now known as seb_kuzminsky
01:22 PM unterhausen: roycroft have you ever had a narex chisel. Thinking of getting a seldom used mortice chisel
01:30 PM roycroft: no, but they are good chisels
01:31 PM roycroft: probably the best value in a wood chisel that one can get
01:31 PM roycroft: my mortise chisels are robert sorby
01:40 PM unterhausen: yeah, not feeling rich enough for sorby rn. I looked at leevalley and they want $220 for the two chisels I want. Rather spend $37
01:56 PM roycroft: i've heard nothing but good things about narex chisels
01:57 PM roycroft: if you get some, just make sure the sides are dead square to the back
01:58 PM roycroft: and i would recommend not hollow-grinding a mortise chisel
01:59 PM roycroft: just grind the primary bevel flat to 30 degrees, and put a small microbevel on it when you hone it
01:59 PM roycroft: and do not go more shallow than 30 degrees on the primary
02:27 PM JT-Shop: I have a couple of sets of narex chisels they are pretty good, you do need to flatten the back on them but almost all chisels you have to do that
02:28 PM roycroft: the only chisels i've ever owned where i did not need to flatten the back are my blue spruce paring chisels
02:28 PM roycroft: but those cost me over $100 each
02:29 PM roycroft: they are magnificent chisels, as they should be for what they cost
02:29 PM * Tom_L wonders how many chisels roycroft owns :)
02:29 PM roycroft: my sorbys - i have both bench chisels and mortise chisels by sorby - all came ground very nicely, but they were ground, not honed
02:30 PM roycroft: and they needed to be flattened and sharpened
02:30 PM roycroft: i bought a medium quality set of japanese bench chisels about 40 years ago, tom_l
02:30 PM roycroft: and i bought the sorby bench chisels and mortise chisels 20ish years ago, over time
02:30 PM roycroft: i've recently purchased the blue spruce paring chisels
02:31 PM Tom_L: you've mostly done woodworking vs metal then
02:31 PM Tom_L: i've mostly done metal
02:31 PM roycroft: i have a pair of two cherries skew chisels
02:31 PM roycroft: yes, wood is my primary medium
02:32 PM roycroft: i have a couple swan neck chisels for scooping out mortises
02:32 PM Tom_L: i did a checkerboard in HS from walnut and ash? i forget now
02:32 PM roycroft: and i have a few oddball chisels from lie-neilsen, buck brothers, etc.
02:32 PM roycroft: less than 30 chisels, total
02:32 PM roycroft: not counting the carving tools
02:32 PM roycroft: which are not really chisels, but gouges
02:33 PM Tom_L: more of a ball handle?
02:33 PM roycroft: actually no
02:33 PM roycroft: i don't like the palm gouges
02:34 PM roycroft: i like to be able to strike them with a mallet
02:34 PM roycroft: my carving tools are mostly pfeil
02:35 PM roycroft: some are hirsch
02:35 PM roycroft: and i ahve a couple flexcut carving knives
02:36 PM * roycroft really needs to get back to making lamps, and is planning on doing so once his mill and lathe are repaired
02:37 PM roycroft: and i'm reminded of something i've been meaning to ask here
02:37 PM roycroft: i want to get a collet chuck for my wood lathe
02:37 PM roycroft: i'm thinking an er40 chuck that will fit the spindle taper (mt3, iirc)
02:37 PM roycroft: for my metal lathe, i'd like a collet chuck as well
02:38 PM roycroft: would a similar one - er40 with a spindle taper, likely be useful?
02:38 PM roycroft: it would not be ideal - a 5c chuck would be ideal, but it would allow me to use the collets i get for the wood lathe, and would at least work for short parts
02:39 PM roycroft: i could perhaps get a 5c down the road
02:40 PM roycroft: i just don't know if it would be a waste of money to get the chuck for the metal lathe
02:40 PM roycroft: the spindle taper is not the same as the wood lathe - it's mt5 - so i could not use the same chuck on both
02:40 PM roycroft: wait
02:40 PM roycroft: except, i could get an mt3 to mt5 adapter, and i could use it on both
02:41 PM * roycroft likes that idea
02:53 PM JT-Shop: I have a 5c chuck for the Samson but you have to hold it with the 4 jaw chuck it's about 5" in diameter
02:56 PM JT-Shop: You will never have to flatten the backs of your Blue Spruce Optima chisels, ever. And, when you unbox your new Optima Chisels, they’re razor sharp and 100% ready to go to work. No sharpening, no honing, no nothing.
02:57 PM JT-Shop: If I did more work with chisels I'd have blue spruce
02:57 PM * JT-Shop goes back to the big cleanup on aisle 1
03:23 PM JT-Shop: hmm, I have a stack of 7" sanding disks but no sander... at one time I had 2...
03:24 PM Tom_L: 7 is an odd size isn't it?
03:29 PM JT-Shop: no 7 and 9 are the big ones
03:30 PM Tom_L: huh
03:30 PM Tom_L: orbital sander?
03:30 PM Tom_L: i thought mine was 8 but maybe not
03:30 PM JT-Shop: angle grinder
03:30 PM Tom_L: ahh
03:31 PM JT-Shop: like your 4 1/2 but take both hands to operate :)
03:31 PM Tom_L: yeah i have a milwaukee
03:31 PM Tom_L: 15" buffing wheels for it
03:32 PM Tom_L: never used it for sanding/grinding
05:04 PM JT-Shop: I just found a package of repair parts from Sears shipped to me 09/24/80!
05:04 PM JT-Shop: just had some allen wrenches in it...
05:06 PM * roycroft has a 7" sander, but rarely uses it
05:07 PM JT-Shop: the $64,000 question is what was in the package and why did I keep it 41 years...
05:07 PM Tom_L: heh
05:08 PM Tom_L: not for the allen wrenches
05:08 PM Tom_L: whatever it was i doubt you can get parts for it now
05:10 PM roycroft: i just ordered parts for my vintage early '80s lathe
05:11 PM JT-Shop: the interesting part is I moved 7 times since I got that package...
05:12 PM JT-Shop: lots of activity on LinuxCNC right now
05:17 PM Tom_L: JT-Shop, big question is though,
05:17 PM Tom_L: did you keep it this time?
05:21 PM Tom_L: stepper to arrive tues but tracking says it's passed the distribution center to the local office so maybe tomorrow...
05:23 PM roycroft: is holding torque the standard metric used for stepper motors?
05:23 PM Tom_L: i think so
05:23 PM roycroft: ok
05:23 PM roycroft: i found the data sheet for mine
05:23 PM roycroft: it's 3Nm, so 425 oz-in
05:24 PM roycroft: and that sounds about right to me
05:24 PM Tom_L: mine are 570
05:24 PM Tom_L: yeah
05:24 PM roycroft: and it might be fine for my router
05:24 PM Tom_L: my last set were 282
05:24 PM Tom_L: probably
05:24 PM roycroft: the gantry will be the biggest load to move, and i'll have two motors for that
05:24 PM Tom_L: yup
05:25 PM roycroft: the x will be easy
05:25 PM roycroft: and the z, i'll test with one of these
05:25 PM roycroft: i need another motor anyway, so if it's not enough i'll get something bigger for z
05:25 PM roycroft: i'm pretty sure the motors i have will be powerful enough to move the z up and down, but i'm not sure about holding power
05:26 PM roycroft: i'm glad i found the spec sheet
05:26 PM Tom_L: mine were cheap
05:26 PM roycroft: i think i paid about $125 for the three motors
05:26 PM Tom_L: 99
05:26 PM roycroft: it's been a few years, so i could be wrong, but that's what i think
05:26 PM CaptHindsight[m]: unterhausen: https://www.youtube.com/watch?v=0nGAZsBi3S0
05:26 PM Tom_L: 119 now
05:26 PM Tom_L: for 3
05:26 PM roycroft: hmm, i got them off ebay, i'm pretty sure
05:26 PM Tom_L: so did i
05:26 PM roycroft: it should be easy to find out how much i paid
05:28 PM Tom_L: https://www.ebay.com/itm/253223632606
05:29 PM Tom_L: those come in 1/4 or 3/8 main shaft
05:29 PM Tom_L: rear is 1/4 on both
05:36 PM roycroft: btw, in case any of you haven't heard, at the g20 summit the president came to an agreement with the eu on tariffs, and it looks like the insane, misguided tariff on european aluminium and steel will be going away soon
05:37 PM roycroft: something he should have done his first week in office
05:51 PM CaptHindsight[m]: roycroft: isn't just more rearrangement of deck chairs on the Titanic?
05:54 PM roycroft: no, this is a positive thing
05:55 PM roycroft: we should see the price of aluminium and tool steel go down soon
05:56 PM CaptHindsight[m]: we could have just upped production here the past few decades but we chose not to
05:58 PM CaptHindsight[m]: https://en.wikipedia.org/wiki/History_of_the_iron_and_steel_industry_in_the_United_States#/media/File:USGS_Iron-Steel_1900-2014.png
06:06 PM roycroft: we don't make tool steel here very much
06:06 PM roycroft: and that's what makes the tariffs so insane
06:07 PM roycroft: our former president was trying to punish the chinese, who do compete with our domestic steel production
06:07 PM roycroft: but the tool steel we import from europe isn't made here
06:08 PM roycroft: i won't get into how moronic it was to put tariffs on eurpoean goods when the chinese are the real target
06:08 PM roycroft: and how utterly stupid the former president was to think that the chinese or europeans would be paying the tariffs, not us consumers
06:08 PM roycroft: i'm not sure that even he is that stupid
06:09 PM roycroft: he probably knew who would pay, but lied about it
06:09 PM roycroft: but anyway, that particular nightmare seems to be ending
06:09 PM XXCoder: i hope that means bump in demend, which means i might get job'
06:10 PM roycroft: and i would 100% agree that we should increase domestic production of vital materials, and not continue to rely on foreign countries for them, no matter how friendly
06:11 PM XXCoder: we'd ened much cheaper method to produce those materials
06:11 PM XXCoder: out for now
06:11 PM CloudEvil: Also the whole not tarrifing finished goods thing, but their raw mateirals
06:14 PM enleth: roycroft: he had a hard time forming a coherent, non-repetetive statement consisting of three sentences
06:14 PM enleth: I'm not sure how much of anything he genuinely "understood"
06:15 PM roycroft: he understands how much he loves himself, and how to manipulate people
06:15 PM roycroft: but je
06:15 PM roycroft: but he is gone now, and hopefully won't be back
06:15 PM roycroft: all we can do now is undo some of the damage he caused
06:15 PM roycroft: and move on
06:16 PM Tom_L: let's in respect for this channel drop this mkay?
06:16 PM roycroft: that's what i'm trying to say now
06:16 PM Tom_L: or go pm with it
06:17 PM roycroft: i just found a 600 oz-in nema 23 motor
06:17 PM roycroft: 570 oz-in is the largest i've ever seen before
06:17 PM Tom_L: i found that one too but decided i liked mine better
06:18 PM roycroft: and an 850 oz-in one that has 3:1 reduction
06:19 PM roycroft: for a router z axis, that shouldn't be a problem, as the range of movement along the z axis is pretty small
06:19 PM roycroft: i'll see how the ones i have work before ordering anything else, but it's good to know there are options without having to move up to nema 34
06:19 PM CloudEvil: https://www.youtube.com/watch?v=ERqikbfoLnw Interesting supply chain issues due to deregulation, and why all your stuff is taking way too long to get here.
06:19 PM CaptHindsight[m]: stepper motor specs are far more important than a slow moving coup
06:19 PM roycroft: not that nema 34 would be a big problem
06:20 PM CaptHindsight[m]: beware of specs that seem out of line for nema23
06:20 PM roycroft: we've been respectfully asked to move on from that topic, capthindsight
06:20 PM roycroft: i think we should respect that request
06:20 PM roycroft: i'm not reading that listing as 850 oz-in plus a 3:1 reduction
06:20 PM roycroft: i'm reading it as effective 850 oz-in with the 3:1 reduction
06:21 PM CloudEvil: 600 vs 570 seems in the range of a measurement issue between makers
06:21 PM CaptHindsight[m]: what those motors have are nema23 mounting holes
06:21 PM roycroft: and that seems quite plausible
06:21 PM roycroft: right
06:21 PM roycroft: that's what nema 23 means
06:21 PM roycroft: a mounting interface spec
06:23 PM CaptHindsight[m]: look at nema34 it's doesn't much of an adapter
06:24 PM roycroft: if i need more torque
06:24 PM roycroft: the ones i have may work fine
06:26 PM Tom_L: the ones i have are pretty stout even if not right on the spec they must be close
06:29 PM Tom_L: CloudEvil, back when i was looking i found something on the 600 from someone that had some that led me to believe it wasn't up to 600 specs
06:29 PM Tom_L: been too long for me to remember much about it now
06:30 PM CloudEvil: Measuring motors has so many fun caveats. Especiually once you want to apply it to an actually useful machine.
06:35 PM CaptHindsight[m]: i wonder where they copied their specs from
06:38 PM Tom_L: it's a standard form you can get off the ninnernet
06:38 PM CaptHindsight[m]: s/look at nema34 it's doesn't much of an adapter/look at nema34, it doesn't require much of an adapter/
06:48 PM CaptHindsight[m]: they likely copied the torque specs for their motor from another motor, not from a standard form
06:50 PM CaptHindsight[m]: I doubt you can get them to publish how they measured the motors output
06:53 PM roycroft: the exact specs do not matter
06:53 PM roycroft: whether the motor does the job is what matters
07:03 PM perry_j1987: so weird
07:03 PM perry_j1987: on the resin printer's screen i can see the layers its suppose to be doing
07:03 PM perry_j1987: if i pause the print it raises it up so i can see what it printed
07:03 PM perry_j1987: and its only printing the supports and not the model lol
07:03 PM perry_j1987: am i missing something here...
07:07 PM skunkwor1s is now known as skunkworks
07:08 PM skunkworks: The Z axis seems to have about .002" backlash
07:10 PM roycroft: i can't say for sure, but i'd guess yes, you are missing something - your model
07:28 PM perry_j1987: try slicing with the stock slicer for anycubic instead
07:28 PM perry_j1987: was trying lychee slicer
08:34 PM -!- #linuxcnc mode set to +v by ChanServ
08:36 PM roycroft: i just got an email from aliexpress seller
08:37 PM roycroft: they are fighting my return still, but said that they would be nice and allow me to return it if i cancel my dispute
08:37 PM Tom_L: hah
08:37 PM roycroft: they said to cancel the dispute, and just use their "free return" service instead of calling it defective
08:38 PM Tom_L: but it is defective..
08:38 PM roycroft: i responded that if i just chose to return it because i do not want it that would be a lie, and i'm not going to lie
08:38 PM roycroft: it's defective, and that is the reason i'm returning it
08:38 PM roycroft: i want it but it is defective
08:38 PM roycroft: i can only think that aliexpress sellers get penalized heavily if they ship defective product
08:39 PM roycroft: which is probably how aliexprss make their money
08:39 PM Tom_L: could be
08:39 PM roycroft: kind of like banks charging obscene overdraft fees
08:39 PM roycroft: anyway, i'm not trying to be mean
08:39 PM roycroft: but i cannot in good conscience say that the product actually is not defective, and that i just changed my mind or something
08:40 PM roycroft: fortunately, the seller does not get the final say
08:40 PM roycroft: but i am weary of this, and i'm sure this channel are weary of it too
08:41 PM Tom_L: fortunately i haven't come across any problems purchasing things online yet
08:41 PM Tom_L: _yet_
08:41 PM roycroft: for the record, when i first found that it was defective, i did not open a dispute
08:41 PM roycroft: i contacted the seller, informing them it was defective, and asking them if they wanted to send me another
08:42 PM roycroft: then the drama started
08:42 PM roycroft: i've had few problems with online purchases
08:42 PM roycroft: but i have had a few
08:42 PM roycroft: i just bought a lot of eight relays that were listed as all identical
08:43 PM roycroft: five of the eight were different when they arrived
08:43 PM Tom_L: figures
08:43 PM roycroft: i contacted the seller and said i wanted to keep the three that were correct and return the rest
08:43 PM roycroft: the seller responded that he had messed up the listing, immediately refunded 5/8 the cost i paid, and told me to keep the others
08:44 PM roycroft: i needed two for my project, so that worked out brilliantly for me
08:44 PM roycroft: and i'll give the seller a good review, without mentioning the problem at all
08:44 PM roycroft: because that was the correct way to handle the problem
08:44 PM roycroft: it's what i would have done
08:45 PM roycroft: not that i'm always correct, but i try to be
08:45 PM roycroft: and if i mess up i try to fix what i messed up
08:46 PM roycroft: i think one of the problem with the chinese vendors is that they have such paper-thin margins it's a big deal when they have to issue a credit for something
08:46 PM roycroft: there are language and cultural differences that get in the way of smooth commerce as well
08:47 PM solarwind: Does anyone know what the automotive propane fittings are called?
08:47 PM solarwind: There are several gas stations in the area that have stations for filling up propane powered vehicles
08:47 PM solarwind: The propane prices are pretty good and I'd like to fill up my own large tanks by fitting an adapter to my 100lb tanks
08:47 PM roycroft: i have no idea what fittings are used for that
08:47 PM Tom_L: Types OF RV Propane Fittings
08:47 PM Tom_L: POL Fittings.
08:47 PM Tom_L: Type 1 (ACME) Fittings.
08:47 PM Tom_L: Inverted Flare Fittings.
08:47 PM Tom_L: NPT Fittings.
08:47 PM Tom_L: Flare Fittings.
08:47 PM Tom_L: Quick-Disconnect Fittings.
08:48 PM Tom_L: 1"-20 (Disposable Cylinder Port) Fittings.
08:48 PM solarwind: they're not RV for cooking use
08:48 PM solarwind: they're for filling up your propane powered vehicle
08:48 PM solarwind: the filling station looks like a regular gas station pump with the handle and everything
08:49 PM solarwind: The price of propane is half the price of gasoline here
08:49 PM roycroft: i wonder if it would be feasible to convert my prius to run propane/battery instead of gasoline/battery
08:50 PM solarwind: Yes, any gasoline engine can run on propane. Except maybe the super advanced modern ones with HCCI
08:50 PM roycroft: i've no idea where i'd put a propane tank though
08:50 PM Tom_L: https://propane.com/for-my-business/fleet-vehicles/propane-autogas-refueling-options/#/find/nearest?fuel=LPG&lpg_secondary=true&country=US
08:52 PM solarwind: Fun fact: POL = CGA 510
08:52 PM solarwind: I was searching for an adapter for the longest time lol
08:52 PM roycroft: solarwind: i'm pretty sure the engine would handle the propane just fine
08:52 PM roycroft: my concern is that the prius' computer system might freak out
08:55 PM roycroft: lng would be better than propane, were i to attempt any kind of conversion
08:55 PM Tom_L: A POL valve (originally for Prest-O-Lite) is a gas connection fitting used on Liquefied petroleum gas (LPG) cylinders. The oldest standard for such connections, it was developed by the Prest-O-Lite company, hence the name. It is still the most common such fitting in some countries such as Australia.
08:55 PM roycroft: less available, but higher energy than propane
08:57 PM roycroft: and apparently it's been done, and needs some custom firmware for the onboard computer to learn how to deal with the lng
08:57 PM solarwind: Barely higher energy density
08:58 PM solarwind: It's more difficult to deal with because of the vapour pressure
08:58 PM solarwind: Actually no, volumetric energy density is lower than propane
08:58 PM roycroft: well both lpg and propane burn a lot cleaner than gasoline
08:58 PM roycroft: mine is an ultra low emission vehicle already
08:59 PM roycroft: the conversion i suppose would make it ultra ultra low
09:23 PM perry_j1987: the motor in this resin wash n cure station sure is a happy little motor sounding lol
09:24 PM roycroft: i'll probably end up getting a resin printer if i ever start casting hardware
09:24 PM XXCoder: depending on what you need, fsm might be good enough
09:24 PM XXCoder: print it, bondo coat it, sand down, glossy paint
09:25 PM XXCoder: like myfordboy does
09:25 PM roycroft: the printers are not that expensive any more, but consumables are still way more expensive than fff printing
09:25 PM roycroft: and that's way too much work
09:26 PM roycroft: if i'm going to be casting, i need to to straight from printer to mold making
09:26 PM XXCoder: theres new 8k hd printer coming out soon too
09:26 PM XXCoder: parts look extremely incible
09:26 PM roycroft: manual post-processing would cost more than the added cost of resin vs. filament
09:26 PM roycroft: maybe myfordboy has more time than money
09:27 PM roycroft: or maybe myfordboy makes more money showing techniques for people who have more time than money
09:28 PM XXCoder: hes likely retired for quite a while now
09:28 PM XXCoder: my guess on his age is around 70 to 80
09:28 PM roycroft: i've seen a video or two of his
09:28 PM roycroft: i don't really remember them
09:28 PM XXCoder: he had partial face shown at one of video and my range is approxately correct
09:28 PM roycroft: i remember not being very interested
09:29 PM XXCoder: you should watch his creation of kiln series though if looking into casting
09:29 PM roycroft: iirc he's one of those people with a "quirky" sense of humor that doesn't work with me
09:29 PM XXCoder: its over decade old now I guess, it looks so worn now lol
09:29 PM XXCoder: he is not.
09:29 PM XXCoder: i like those humor sometimes, though only to extent
09:30 PM XXCoder: but he dont do that humor
09:30 PM roycroft: my recollection must be incorrect then
09:31 PM roycroft: i just remember hearing about him a long time ago, checking out some videos, and not finding them interesting for whatever reason
09:34 PM XXCoder: hes pretty good. just once a while annoying 3d printer video due to patron or something
09:34 PM perry_j1987: lol layer shifting on resin prints...
09:34 PM perry_j1987: thats what i just got
09:34 PM XXCoder: he dont do some crappy ad-video in most case, he actually does stuff with printed item like casting
09:34 PM XXCoder: perry what
09:35 PM roycroft: anyway, the high cost of resin printing is not that big a deal when it comes to casting
09:35 PM roycroft: only a single printed part needs to be made
09:36 PM roycroft: a mold can be made from that, and that mold used to make as many positive molds as needed
09:37 PM perry_j1987: you know how layer shifting looks on fdm printers?
09:37 PM roycroft: yes
09:37 PM perry_j1987: i just pulled my first print out of this anycubic photon mono
09:37 PM perry_j1987: and it looks like layer shifting lol
09:37 PM roycroft: sounds like it might not be calibrated properly
09:38 PM perry_j1987: im trying to wrap my head around how its possible
09:38 PM perry_j1987: the flex plate doesnt look like it shifted at all
09:39 PM roycroft: the elegoo mars 2 is what i've been looking at
09:40 PM roycroft: your slicing software may need adjustment
09:40 PM perry_j1987: 200 bucks on amazon for a wash n cure and resin printer from anycubic mono right now
09:41 PM roycroft: i don't think i've looked at anycubic mono printers
09:41 PM CaptHindsight[m]: resin printer to print the mold
09:41 PM roycroft: the elegoo mars are in that price range
09:41 PM CaptHindsight[m]: to make money with resin printers you need to make your own resin
09:41 PM perry_j1987: https://amzn.to/3EzqH6s
09:42 PM XXCoder: not avilible
09:42 PM perry_j1987: oh darn
09:42 PM perry_j1987: its roughly same price to get them individually right now too on amazon
09:42 PM XXCoder: https://www.amazon.com/gp/product/B08FR39QJ7/
09:42 PM perry_j1987: thats what i did and i ended up getting a bottle of the plant based resin for an extra 7 bucks
09:42 PM XXCoder: might be good for you, its monochrome, one of cheapest on that type
09:43 PM CaptHindsight[m]: https://www.amazon.com/ANYCUBIC-Photon-Printer-Printing-Monochrome/dp/B08Q394GQ1/ref=sr_1_6
09:43 PM roycroft: the elegood mars 3 has a larger print envelope than the anycubic mono
09:43 PM roycroft: i'm not buying any new printers at the moment
09:43 PM roycroft: by the time i do, there may well be completely different offerings
09:44 PM roycroft: i'll buy another filament printer before i buy a resin printer
09:44 PM XXCoder: yeah 8k might become common then
09:44 PM XXCoder: https://3dprintingindustry.com/news/phrozen-launches-its-sonic-mini-8k-3d-printer-and-new-resin-technical-specifications-and-pricing-197275/
09:44 PM XXCoder: look at print pictures. insane.
09:45 PM perry_j1987: cool time to be alive heh
09:46 PM CaptHindsight[m]: those are all bottom up projection, so you only have a limited range of resins that will flow through it
09:46 PM roycroft: for the time being
09:47 PM CaptHindsight[m]: and you place tension on the print each l;ayer
09:47 PM CaptHindsight[m]: nope for quite some time
09:47 PM CaptHindsight[m]: physics
09:48 PM roycroft: i wa referring to the "cool time to be alive" comment
09:48 PM CaptHindsight[m]: one never knows
09:48 PM roycroft: correct
09:48 PM roycroft: one has concerns, though
09:49 PM CaptHindsight[m]: just build a top projection type
09:49 PM roycroft: one will respectfully not elaborate on those concerns on this channel this evening
09:49 PM CaptHindsight[m]: then you can even print metals and ceramics
09:50 PM XXCoder: I want SLS machine lol
09:50 PM XXCoder: but its so hard to use and expensive :(
09:51 PM CaptHindsight[m]: you can build an SLS for under $1k now for plastics
09:51 PM CaptHindsight[m]: galvos are cheap now
09:51 PM XXCoder: i suppose, but im rather lacking skills on that
09:52 PM roycroft: todd rundgren was finally inducted into the rock and roll hall of fame
09:52 PM CaptHindsight[m]: top projection can print with thermoplastic powders and resin
09:52 PM roycroft: so something good has happened :)
09:52 PM CaptHindsight[m]: it's even faster and lower cost than binderjet
09:53 PM roycroft: a couple decades late, but better late than never
09:53 PM roycroft: carole king as well
10:25 PM david_ is now known as Guest1918
10:26 PM CaptHindsight[m]: I guess the rock and roll hall of fame doesn't have anything to do with slow moving coups so we can mention it here without complaints, noted
10:27 PM CaptHindsight[m]: XXCoder: https://www.youtube.com/watch?v=OjjczQkK2zM
10:28 PM XXCoder: thanks
10:29 PM infornography: What do you call the plastic things that snap together and guide the wires and hoses for the axis of the cnc?
10:29 PM XXCoder: wire belts?
10:30 PM CaptHindsight[m]: use it as a guide to DIY it
10:30 PM XXCoder: yea saving it, though its not likely for me to make one anytime soob
10:30 PM CaptHindsight[m]: infornography: cable chain
10:30 PM Tom_L: drag chain
10:31 PM Tom_L: cable chain
10:31 PM infornography: Yes! Thank you

10:33 PM Tom_L: tiny
10:33 PM Tom_L: well the one shown is
10:34 PM CaptHindsight[m]: XXCoder: https://www.alibaba.com/product-detail/Galvo-Head-Accurate-Sino-Auto-Focus_1600191846370.html these used to cost thousands
10:37 PM CaptHindsight[m]: XXCoder: you could repurpose an old FFF printer or CNC router to be an SLS printer
10:38 PM XXCoder: that machine unloading system can be designed better
10:38 PM CaptHindsight[m]: needs a powder bed and for best results an enclosure for inert gas and a heated bed
10:39 PM CaptHindsight[m]: but you can SLS thermoplastics without inert gas, it just helps
10:39 PM XXCoder: for nylon, also dry air
10:39 PM CaptHindsight[m]: if you add a heated bed you get both heat and dry
10:40 PM CaptHindsight[m]: polyester powder coats are a low cost source for SLS powders
10:41 PM XXCoder: lol cool
10:41 PM CaptHindsight[m]: not ideal but they work to make parts
10:41 PM david_ is now known as Guest5684
10:41 PM XXCoder: whats properies like on those
10:42 PM david_ is now known as Guest6029
10:46 PM CaptHindsight[m]: https://powdertechnology.com/super-durable-polyester
10:47 PM CaptHindsight[m]: to DIY a binderjet you can use http://ytec3d.com/hp45-inkjet-printhead/
10:47 PM CaptHindsight[m]: they RE'd the interface so you can build your own inkjet
10:48 PM CaptHindsight[m]: same for https://ytec3d.com/forum/viewtopic.php?t=47
10:56 PM perry_j1987: how soon do you have to get to a finished resin print to clean it
11:38 PM CaptHindsight[m]: perry_j1987: a few years IF kept away from light
11:56 PM CaptHindsight[m]: if you let them sit for long enough most of it will just run off, heating will lower the viscosity of the uncured resin if you want to speed that up
11:57 PM CaptHindsight[m]: but if you heat it up >60-70C you risk triggering polymerization
11:58 PM perry_j1987: k
11:59 PM perry_j1987: ya was wondering about starting prints through the night etc
