12:21 AM roycroft: uri tuchmann has a new video
12:30 AM roycroft: he's making a carved, all-metal computer mouse
12:30 AM roycroft: out of brass, of course
12:30 AM XXCoder: of course
01:36 AM Deejay: moin

04:59 AM Tom_L: morning
05:06 AM mrec: Tom_L: did you get any documentation about modbus?
05:12 AM Tom_L: not really, i don't think it is enabled on mine however they did send me some in chinese i translated
05:14 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/PDF/BLDC/
05:14 AM Tom_L: that's all i got
05:24 AM mrec: that's some more than I got so far I asked for more already and I'm waiting for them.
05:32 AM JT-Cave: morning
01:59 PM roycroft: we've been continuing to receive a steady stream of complaints about our vaccinatin policy for the country fair
01:59 PM roycroft: i noticed a similarity in the type of language used in many of the complaints, and especially the syntax of the sentence structures
01:59 PM roycroft: so i decided to do a little digging
02:00 PM roycroft: and when i do search engine searches on the email addresses that sent the complaints, i find the top hit for a large number of them is the same russian-language page on facebook
02:01 PM * roycroft finds that rather curious, but not surprising
02:02 PM roycroft: this report is merely anecdotal, but i looked up 50 "suspicious" email addresses, and 37 of them point to that facebook page
02:14 PM -!- #linuxcnc mode set to +v by ChanServ
02:37 PM roycroft: everything is expensive these days
02:37 PM unterhaus: roycroft, how are you hanging dust collection ducting?
02:38 PM roycroft: plumbers tape, bungee cords, and whatever else works
02:38 PM unterhaus: I was hoping to do something more better than plumbers tape, but if it doesn't exist...
02:38 PM roycroft: fire up your cnc router and make some plywood hangers
02:39 PM unterhaus: yeah, about that nonexistent router
02:39 PM roycroft: if it's 4" ducting, you can buy expensive hangers from rockler
02:39 PM roycroft: if it's bigger than that, i'd go with plumber's tape
02:39 PM unterhaus: expensive == bad
02:39 PM unterhaus: I printed some 4" hangers, haven't set them up yet
02:40 PM unterhaus: going to run a duct along the back of my tablesaw to get it to the ducting running along the top of the wall
02:40 PM roycroft: and i just discovered that all the boxes i've printed so far (very few, fortunately), are the wrong height
02:40 PM XXCoder: doh
02:41 PM roycroft: i've no idea how that happened, but it did
02:41 PM roycroft: as far as wrong dimensions go, having them too short is the one that i can live with
02:41 PM roycroft: too tall, impossible
02:41 PM unterhaus: XXCoder, got some usb connectors for the MPM, not sure I'm up to installing one though
02:41 PM roycroft: off in x or y, impossible
02:42 PM * roycroft rebuilds all his models, and decides to do a sample print of each before doing a commit
02:42 PM XXCoder: sounds like not out of prototyping stage yet heh
02:42 PM unterhaus: so are they too tall then?
02:43 PM roycroft: no, they are too short
02:43 PM roycroft: i thought i was, xxcoder
02:43 PM unterhaus: so usable
02:43 PM roycroft: but apparently i have one more round of prototyping
02:43 PM roycroft: yes, i can use them, for now a least
02:44 PM XXCoder: ALWAYS print apparently final design alone. lol
02:44 PM roycroft: more than likely, it will bug me down the road and i'll reprint them
02:44 PM roycroft: but there are only about 15 boxes printed so far at that wrong height
02:44 PM unterhaus: I printed a batch of my duct holders and then made a much better design. Sometimes I just have to hold things in my hand
02:44 PM roycroft: and most of those are with the original tab design, which i do not like
02:44 PM XXCoder: well can use those for "holding on table"
02:45 PM unterhaus: print an extension :)
02:45 PM unterhaus: sell them on ebay
02:45 PM Tom_L: well yesterday i set up a new ballnose in my tool list and for some reason it set to sfm instead of ipm and i couldn't figure out why the job was gonna take 5 hrs
02:45 PM Tom_L: i cut it in 40 min yesterday after fixing the tool
02:46 PM roycroft: i'm going to step back, make sure every dimension is table-driven, print a single sample of each size, confirm that it's correct, then set up multi-box batches, and do a test print of every configuration of that, measuring a sample from each
02:46 PM roycroft: then it will all go in a git commit, and i'll be able to start printing at will
02:50 PM XXCoder: awesome
02:50 PM XXCoder: you dont use printables site?
02:50 PM unterhaus: I just found the pencil that roycroft made me buy
02:56 PM unterhaus: there is a design for a 3d printed holder for wera hex wrenches that I found, but it doesn't hold the 10mm because "nobody uses that"
03:13 PM roycroft: nobody uses one of the most commonly used wrenches?
03:45 PM MrSunshine: JT-Cave or pcw--home, would a cable from a parport card fit a mesa 7i92 ? its from a card that has two parports but has an extension cable for the 2nd one =)
03:55 PM unterhaus: the cable should work
03:56 PM unterhaus: Peter is thoughtful like that
04:00 PM roycroft: some parallel port cables do not have all 25 pins connected
04:00 PM roycroft: any that are sold by mesa will, but some random ones do not
04:01 PM roycroft: unless you're talking about a ribbon cable, which should have all 25 pins connected straight-through
04:02 PM roycroft: it's external db-25 cables that are not always fully pin-populated
04:04 PM JT-Shop: MrSunshine, if it's a 7i92 and not a 7i92M DB25M to DB25M IEEE 1284 compliant parallel port cable https://mesaus.com/product/db25m-db25m/
04:04 PM MrSunshine: 7i92M, has one parport and one "pin header"
04:04 PM JT-Shop: for short runs you can use a ribbon cable
04:05 PM JT-Shop: https://mesaus.com/product/db25f-idc26-bracket/ - the bracket for the header
04:05 PM MrSunshine: JT-Shop, yeah its a ribbon cable but i want it to another breakout board i have laying around.. so was wondering if the port for ribbon cable is designed for parallel port ribbon cables or some special mesa ? =)
04:06 PM MrSunshine: yeah looks just like that the ones i have
04:06 PM JT-Shop: https://mesaus.com/product/db25f-idc26/
04:06 PM CaptHindsight[m]: MrSunshine: it's all standard stuff
04:06 PM JT-Shop: the IDC 26 pin connector has the first 25 pins connected
04:07 PM CaptHindsight[m]: they didn't get cute or fancy trying to create proprietary cables and connectors
04:07 PM MrSunshine: aight =)
04:07 PM MrSunshine: good to know =) then i can expand with 5 more inputs and a bunch of outputs for the ATC spindle etc =)
04:08 PM MrSunshine: with stuff just laying around waiting for a project =)
04:09 PM CaptHindsight[m]: MrSunshine: just look out for cheap LPT cables that leave out conductors. Some are made so poorly that they may only work over a short distance.
04:10 PM MrSunshine: CaptHindsight[m], these are old cards from the pci maybe even ISA era =) that had 1 port on the actual card and one ribbon cable with it for the 2nd port .. hopefully they didnt skimp out back then =)
04:10 PM CaptHindsight[m]: MrSunshine: look for IEEE 1284 with the DB25's the way you want
04:11 PM CaptHindsight[m]: males vs females in the combo you need
04:12 PM CaptHindsight[m]: if you order from JT or Mesa you'll be sure that they work, if in doubt or run into problems
04:12 PM roycroft: i wouldn't say that lpt cables are "made poorly"
04:13 PM roycroft: they're made just well enough to function properly for their intended purpose
04:13 PM MrSunshine: CaptHindsight[m], well im in europe =) costs a fortune to get stuff chipped if people even ship here and takes a month =)
04:13 PM roycroft: passing signals to a bob is not the purpose of an lpt cable
04:13 PM MrSunshine: ill just look up the datasheet and check the cables for the right pin order =)
04:14 PM roycroft: if it's a ribbon cable the pin order automatically determined, unless the individual wires are broken out and twisted about
04:14 PM roycroft: s/order/order is/
04:14 PM roycroft: just make sure you connect the end with the red stripe to pin 1
04:15 PM MrSunshine: now to close up the chicken coup and go to bed =)
04:15 PM MrSunshine: roycroft, they have a key also so shouldnt be wrong there but thanks for that also =)
04:15 PM roycroft: they do, but some of the card edge connectors are not housed, so the key doesn't matter
04:16 PM MrSunshine: roycroft, the mesa 7i92m is housed and have a slot for the key atleast =)
04:16 PM roycroft: and the only issue with where you connect pin 1, other than making sure it's consistent on both ends, is that a parport uses 25 pins, but uses a 26 pin connector, since the connector pins are in pairs
04:17 PM roycroft: some parport ribbon cables have a 25 conductor cable, with the 26th pin not connected, and some have 26 conductor cables
04:17 PM CaptHindsight[m]: you can always plug socket 26
04:17 PM roycroft: if you get it backwards with the former, then the unused pin (26) is connected, which should not matter, but pin 1 would not be connected, which definitely would matter
04:18 PM roycroft: and some cables do that, capthindsight
04:18 PM CaptHindsight[m]: or snip pin 26
04:18 PM roycroft: and while i'd say that connecting all 26 pins on an lpt cable is a case of overengineering, plugging pin 26 on a ribbon cable socket that only uses 1-25 is appropriate and should be done
04:19 PM roycroft: snipping pin 26 still allows the cable to be installed incorrectly
04:19 PM roycroft: you have to both snip it and plug socket 26 to properly configure the ribbon cable so that it can only be installed correctly
04:19 PM MrSunshine: but a "bad" cable shouldnt damage the mesa card as there is no power comming over the parport right ? =) only GND and IOs .. so in worst case it would just ground some IOs
04:20 PM CaptHindsight[m]: ever just plug them in without looking and use a hammer if they don't slide in easily?
04:20 PM Tom_L: isn't that proper procedure?
04:21 PM roycroft: never have i ever used a hammer to install a ribbon cable
04:21 PM CaptHindsight[m]: works if you try it enough times
04:21 PM MrSunshine: im voting for hammer
04:21 PM MrSunshine: just like puzzles
04:21 PM MrSunshine: cant win without a hammer
04:21 PM Tom_L: i use my vice to smash the idc connectors
04:22 PM CaptHindsight[m]: scissors for puzzles saves time
04:22 PM MrSunshine: hate it when they put the key on the wrong side of the piece
04:23 PM roycroft: grr
04:23 PM roycroft: so elon musk now owns twitter
04:23 PM roycroft: it's difficult for twitter to become even worse than it is, but a musk ownership guarantees that will find a way to happen
04:24 PM MrSunshine: but .. he got rockets!
04:24 PM XXCoder: yep logged out on twitter. doubt will log in again
04:24 PM * roycroft never joined
04:24 PM JT-Shop: yippie the new handles for the #5 showed up today
04:24 PM roycroft: i have no idea what's going on with my slicer
04:24 PM JT-Shop: gotta knock the fuzz off and decide how to finish them
04:25 PM roycroft: i just saved a file in sw that i was sure was correct before, and confirmed is correct
04:25 PM roycroft: i exported it to stl
04:25 PM roycroft: i loaded it in cura
04:25 PM roycroft: it is supposed to be 49.5mm high
04:25 PM roycroft: cura says the model is 49.5mm high
04:25 PM roycroft: so i sliced it
04:26 PM Tom_L: doesn't sw slice n dice them too?
04:26 PM roycroft: i saved it
04:26 PM roycroft: i loaded it into octopi
04:26 PM roycroft: which says it's 43.6mm high
04:26 PM roycroft: i did the exact same thing with another variant of the file
04:26 PM XXCoder: I only use cura for older mini select mp machine. because of workable profile
04:26 PM roycroft: and octopi says that one is 49.5mm high
04:27 PM roycroft: i'm not married to using cura
04:27 PM XXCoder: otherwise I use prusaslicer. you should use superslicer. which is fork of prusaprinter
04:27 PM roycroft: i use it because when i got my printer it had a profile for my printer,a mac os desktop version, and it worked well
04:27 PM roycroft: i'll look into superslicer
04:27 PM roycroft: i've been chasing down this problem, thinking it was something i had done in sw
04:28 PM roycroft: but my models all seemed fine
04:28 PM XXCoder: send me model ill check it over
04:28 PM roycroft: i'm not sure if it's the slicer itself causing the issue, or the way octopi is interpreting the gcode
04:28 PM XXCoder: the stl
04:28 PM XXCoder: octopi might be reading wrong layer height. that'll affect height by a whole lot.
04:29 PM _unreal_: so just got home, and starting to mill with the new bits that arrived
04:30 PM Tom_L: how many did you break already?
04:30 PM CaptHindsight[m]: 👍️
04:31 PM Tom_L: i wound up changing my model to use a 1/16 ball nose for the whole thing
04:32 PM XXCoder: 24.76 height according to prusaslicer
04:33 PM XXCoder: oops
04:33 PM XXCoder: 49.53
04:33 PM roycroft: ok, that's close enough
04:33 PM XXCoder: looked at Z position not size lol
04:33 PM Tom_L: must be the new math...
04:34 PM roycroft: the new math is racist, allegedly
04:34 PM roycroft: we need to go back to using an abacus
04:34 PM XXCoder: only white numbers is greek numbering system
04:35 PM roycroft: the greek numbering system was discriminatory
04:35 PM XXCoder: https://imgur.com/1oXwBiU.png
04:35 PM roycroft: it excluded the zeros
04:35 PM Tom_L: zero doesn't count for anything
04:36 PM Tom_L: it's like having somebody stand in the good parking spot while you circle around to park
04:37 PM * Tom_L bets roycroft doesn't do that :)
04:37 PM XXCoder: 0 is not negative... nor postive
04:37 PM roycroft: it should be 49.5x24.75x49.5
04:37 PM roycroft: so prusa groks the model just fine
04:37 PM roycroft: i don't, tom_l
04:37 PM Tom_L: XXCoder, it can't make up it's mind
04:37 PM roycroft: you know me too well
04:38 PM Tom_L: well i wouldn't either
04:38 PM roycroft: it's not a nice thing to do
04:38 PM roycroft: and i wouldn't expect you would do it
04:38 PM roycroft: nor most folks here
04:39 PM roycroft: when this print is finished i'll load that model into octopi, xxcoder
04:39 PM roycroft: and see what octopi thinks about it
04:39 PM XXCoder: ok
04:39 PM roycroft: cura's sense of the dimensions are correct within the app
04:40 PM roycroft: it's the gcode it produces that may be the source of the problem
04:40 PM roycroft: or it may be that octopi is the problem
04:40 PM roycroft: i guess i can look at the gcode and see if something jumps out at me as wrong
04:41 PM XXCoder: yeah
04:41 PM XXCoder: whats layer height you slice at?
04:41 PM roycroft: 0.32mm
04:41 PM roycroft: keep in mind that i have a volcano hot end with a 0.8mm nozzle, and i want to print as fast as possible
04:42 PM XXCoder: interesting. well its possible that octo is assuming .2
04:42 PM XXCoder: that would strunk height by a lot. checked math of octo height vs .32/.2?
04:42 PM roycroft: G0 F6000 X89.022 Y118.594 Z0.32
04:42 PM roycroft: it looks like it's being told to move 0.32mm
04:43 PM XXCoder: so gcode is correct, in least seems so. check next layer
04:43 PM roycroft: G0 F300 X129.67 Y101.805 Z0.64
04:44 PM XXCoder: well seems correct
04:44 PM roycroft: G0 F300 X131.518 Y119.557 Z0.96
04:44 PM roycroft: i think this version may be correct
04:44 PM roycroft: i'll find out when i print it
04:44 PM roycroft: all i did was reopen the model in sw, confirm the settings, save it, export it, open it in cura, slice it, and save it
04:45 PM roycroft: without making any changes to the model in sw, nor any changes in the slicer settings
04:45 PM roycroft: it works out to be 156 layers
04:45 PM roycroft: and the last time i printed it it was 137 layers
04:45 PM roycroft: which is the number of layers of all the prints that were too short
04:46 PM roycroft: all generated from different files
04:46 PM roycroft: so something really odd is/was happening
04:46 PM roycroft: but i won't waste any more filament - i can check how many layers octopi intends to print before the print job starts
04:46 PM XXCoder: indeed
04:46 PM XXCoder: and check if it lists layer height
04:47 PM roycroft: it doe
04:47 PM roycroft: s
04:47 PM roycroft: it's always 0.32mm, even when it's printing incorrectly
04:47 PM XXCoder: hm sounds somethings broken
04:47 PM roycroft: yes
04:48 PM roycroft: and i actually have been making one change in the slicer, which should not matter but if there's a bug in the software it could
04:48 PM roycroft: on that model i sent you it's a half depth box
04:48 PM roycroft: i.e. two of those make up one standard size box
04:49 PM roycroft: and because of that, i left the lifting tab off the top, because it covers too much of the box and i can't get my finger in it to lift
04:49 PM roycroft: so i turned off supports in the slicer when i loaded that
04:49 PM roycroft: and turned it back on when loading the bigger boxes
04:50 PM roycroft: but both that model and some of the bigger ones were printing too short, even when supports were turned on
04:50 PM roycroft: i realized that if i don't have the tab, no supports will be generated anyway, so now i'm just leaving supports turned on for all the models
04:51 PM roycroft: anyway, i'll look up that superslicer software and see if there's a mac os port, and if so, i'll give that a go
04:52 PM roycroft: cura tends to start beachballing after a while anyway - it must have a memory leak
04:52 PM roycroft: oh, super slicer requires installing brew
04:53 PM roycroft: that may be why i haven't tried it - brew tends to make big messes
04:54 PM XXCoder: that sucks
04:54 PM XXCoder: prusaslicer dont so far I know
04:55 PM XXCoder: you just use appimage directly and thats it for linux
04:55 PM _unreal_: That was ODD. my phone turned off hot spot on its own
04:55 PM roycroft: there's a newer version of cura
04:55 PM _unreal_: in anycase
04:55 PM _unreal_: WOW totally impressed with the $12 special
04:55 PM roycroft: when i get a chance i'll update
04:56 PM _unreal_: I'm still on my first BIT and have yet to break a bit
04:56 PM roycroft: and cura 5.0 is in beta
04:56 PM _unreal_: already made 3 passes. infact I just spend up the feed rate from 26mm to 35mm/min
05:11 PM tcurdt: Yay! The 7i92 arrived! I didn't think I'd mange to get my hands on a mesa card that fast.
05:11 PM tcurdt: granted - not the one I wanted ... but should do the job.
05:11 PM XXCoder: :)
05:11 PM t4nk_freenode: _unreal_, I got some hardwood plywood for a base today
05:12 PM t4nk_freenode: figured it would be better than mdf
05:12 PM t4nk_freenode: got it cut to size so I won't have a chance to mess it up myself ;)
05:13 PM tcurdt: is there a place where people share their mesa/linuxcnc configs? I know it's all very individual ... but I think just looking at some configs will help me to get started more easily
05:18 PM roycroft: have any of you ever seen/used eucalyptus plywood?
05:18 PM t4nk_freenode: nope, probably smells nice ;)
05:18 PM _unreal_: t4nk_freenode, this machine I'm building/rebilding has a hardply/MDF hybrid
05:18 PM _unreal_: I have MDF on the bottom and ply on the top glued with epoxy
05:18 PM roycroft: with the shortage of baltic birch ply, which will probably not change for a very long time, folks are starting to turn to that product
05:19 PM roycroft: it's a high quality void-free material
05:19 PM roycroft: slightly fewer plies than baltic birch (11 vs 13 in 18mm thickness), and the face plies are as thick as baltic birch
05:20 PM roycroft: supposedly a very good substitute, and less expensive
05:20 PM _unreal_: eucalyptus? huh.... ya never thought about using that.
05:20 PM roycroft: unfortunately the majority of it is produced in china, so it has its own geopolitical problems
05:20 PM _unreal_: still on the first bit no breaks and cutting like a champ
05:20 PM roycroft: but there is a fair amount made in australia and other parts of southeast asia as well
05:21 PM t4nk_freenode: _unreal_, I got some 18mm and 12mm plywood now, but the piece for the base is cut from 12mm, coincidentally I thought of putting it on top of mdf too today
05:21 PM roycroft: i've never seen it, but i've been reading about it lately
05:21 PM t4nk_freenode: but nah, maybe with the final machine
05:21 PM _unreal_: when this cut is done I'll make a choice and likely purchase like 2-3 more boxes of these cheap 3 flute bits
05:21 PM roycroft: i'm going to check with my local suppliers and see if any of them are going to get some - there are three suppliers i use who do a lot of architectural stuff, and moved a *lot* of baltic birch plywood when it was available and affordable
05:21 PM _unreal_: t4nk_freenode, when it comes to PLY I would suggest stacking them.
05:22 PM t4nk_freenode: anyhow, got a nice supply of plywood now
05:22 PM _unreal_: I would also suggest having supports across the bottom
05:22 PM roycroft: setting up a new supply chain to get the eucalyptus ply could take months, though
05:23 PM t4nk_freenode: now I can just leave the current machine in tact, and just start on the new base
05:25 PM JT-Shop2: 000 seems to do ok smoothing the end grain of the #5 rear handle
05:26 PM _unreal_: t4nk_freenode, square tube or angle aluminum for the supports on the bottom. the idea is when you bolt the extrusion to the ply for the main Y rails, that will keep it from flexing that way. the cross supports I just suggested go on the X axis under the ply wood.
05:27 PM _unreal_: your call if you do that but thats what I did with my build
05:27 PM _unreal_: I also used my small cnc to build legs for the new machine
05:27 PM _unreal_: my new cnc has 12 legs under
05:28 PM _unreal_: left right side 4, and 4 in the middle
05:28 PM * roycroft is printing the small model now that was too short before
05:28 PM roycroft: octopi thinks it is correct, so i'll see
05:28 PM _unreal_: and foam pads under every foot.
05:29 PM _unreal_: roycroft, I always have scale issues with 3d printing
05:29 PM t4nk_freenode: my rails aren't gonna flex, they are sturdy beams... and only around 50cms too for this build, so I hope I'm good
05:30 PM JT-Shop2: roycroft: what kind of finish should I put on these new Stanley #5 handles?
05:31 PM t4nk_freenode: for the bigger build, I'm going to weld something decent
05:33 PM roycroft: what kind of wood are they made of, jt-shop2?
05:34 PM JT-Shop2: walnut
05:34 PM roycroft: i'd use some tried and true varnish oil, and then perhaps a dab of alfieshine wax after a few weeks
05:35 PM _unreal_: eeeeeeeeeeek squeeling
05:35 PM JT-Shop2: thanks, never heard of alfie shine
05:35 PM _unreal_: that aluminum clearly has hard and soft spots
05:35 PM roycroft: get some
05:35 PM roycroft: you'll love it
05:36 PM roycroft: it smells wonderful
05:36 PM t4nk_freenode: lol, _unreal_ those are probably bit-bits returning from outter-dimensions
05:36 PM _unreal_: t4nk_freenode, I'm almost done cutting the first of two vertical Y/x arms
05:36 PM roycroft: and a tiny bit goes a long way - it has resin embedded in the wax, so a really thin coat hardens nicely, and leaves a soft patina
05:36 PM roycroft: it's expensive, but a little tin will last you a very long time
05:37 PM _unreal_: when I get the big upper sections cut. I'll move onto cutting the large 3/8th " thick aluminum angle
05:37 PM JT-Shop2: a tin will be here Wednesday!
05:37 PM _unreal_: that is the interface to go between my carriages and the Y/x arms
05:37 PM roycroft: awesome!
05:38 PM roycroft: it's one of the main waxes i use
05:38 PM _unreal_: ughh... once I finish this cut out. I still have heavy duty tabs holding the part down. I need to mill 4 more holes for the leveling
05:38 PM roycroft: rennaissance wax is another one that i like a lot, but not for wood
05:39 PM roycroft: it's great on metals and plastics though
05:42 PM t4nk_freenode: _unreal_, got any pictures, or some vids of the cutting in action?
05:42 PM t4nk_freenode: and you're still not using any lube for cutting/
05:43 PM roycroft: i just got some new saw files in the mail, and they have nice, sharp corners
05:44 PM _unreal_: t4nk_freenode, ?
05:44 PM _unreal_: the current job
05:44 PM _unreal_: nope no lube cant
05:45 PM t4nk_freenode: yeah, I'd like to see the cutting in action
05:45 PM _unreal_: these are the dirt cheap bits I ordered https://www.amazon.com/dp/B098DV79ZL?psc=1&ref=ppx_yo2ov_dt_b_product_details
05:45 PM _unreal_: I'm using my phone right now as my internet dont really have an easy way to undo it for video :s
05:47 PM _unreal_: looks like elon buying twitter is a done deal
05:47 PM _unreal_: sweet
05:47 PM t4nk_freenode: yeah, that's unbecomingly cheap
05:51 PM _unreal_: got like two more passes and the big cut is done. SOOO nice
05:52 PM t4nk_freenode: well, pics, or it never happened.
05:52 PM _unreal_: at this rate never happend ;)
05:52 PM _unreal_: I can snap some photos with something else
05:54 PM _unreal_: booting up a tablet
06:07 PM infornography: you must provide evidence, because your claims seem _unreal_
06:08 PM infornography: >_>
06:08 PM -!- #linuxcnc mode set to +v by ChanServ
06:08 PM infornography: those are some long ass endmills for 1/8th
06:10 PM XXCoder: can someone link me pctures?
06:10 PM XXCoder: client closed
06:13 PM t4nk_freenode: he may be refering to these: https://www.amazon.com/dp/B098DV79ZL?psc=1&ref=ppx_yo2ov_dt_b_product_details
06:13 PM XXCoder: bit long, but not expecially so
06:16 PM _unreal_: I'm still on the first bit
06:16 PM _unreal_: cutting like a champ
06:19 PM _unreal_: ugh... so loud
06:19 PM _unreal_: still amazed my 300 watt is milling like a champ
06:19 PM infornography: some sort of fancy high speed spindle?
06:19 PM _unreal_: and its holding at 15k rpm
06:20 PM _unreal_: in a way yes
06:20 PM roycroft: um, i think you mistyped that, infornography
06:20 PM _unreal_: I have a micro heavy duty spindle
06:20 PM roycroft: let me correct it for you
06:20 PM _unreal_: infornography, no error
06:20 PM roycroft: "you must provide evidence, because your CLAIMS seem _unreal_"
06:20 PM _unreal_: roycroft, just wants there to be an error
06:21 PM t4nk_freenode: yeah, make us a little vid of the cutting in action man... we want to hear the squealing for ourselves
06:22 PM t4nk_freenode: got me so curious I'm bursting
06:22 PM * roycroft has two prints done, measured, and confirmed to be the correct dimensions, is working on the third now, and has three more to do after that one
06:22 PM roycroft: these are the 1-up test prints
06:22 PM roycroft: i still have multiple box prints to do, and i suppose i should test all those variants before i commit to starting the production run
06:23 PM t4nk_freenode: unplug your phone for a sec, _unreal_ ... "we'll wait for you right here."
06:23 PM roycroft: i can't do any more real work on my cabinet design until the drawer slides arrive so i can measure them and ensure that my layout will fit
06:23 PM roycroft: perhaps i should spend some time on the cnc router design in the meantime
06:24 PM roycroft: i have the new gpu working fine now, and solidworks can handle the drawings without frustrating me
06:25 PM roguish[m]: roycroft: hey. recall you mentioned maybe getting a Quadro 4000 graphics card? well, mine crashed twice today..... they have a known problem. Nvidia even admits to it.....
06:25 PM infornography: we were looking into high speed spindles to ad on to our existing machines at work. We ended up getting some sort of R8 grinding head attachment that has worked well. But we lose like 7 inches of z travel. So not ideal...
06:25 PM infornography: Sorry, slow type
06:25 PM infornography: lol
06:26 PM _unreal_: this is the spindle on my current small cnc machine
06:26 PM _unreal_: https://www.aliexpress.com/item/4000801582283.html?spm=a2g0o.order_list.0.0.21ef1802XSPjRF
06:26 PM _unreal_: sorry took me a second to find it. could not remember if it was on alibaba or aliexpress
06:26 PM roycroft: i ended up getting a p600
06:26 PM _unreal_: if you look at the photo of the spindle its self. the shaft is solid
06:26 PM _unreal_: p600?
06:26 PM roycroft: i wanted the pascal family gpu, after reading about it more
06:26 PM roycroft: but i don't need super high performance
06:27 PM roycroft: nvidia p600 gpu
06:27 PM roycroft: i'm not designing rocket ships
06:27 PM roycroft: just the occasionall cnc machine
06:27 PM roguish[m]: that one sounds good
06:27 PM _unreal_: infornography, what are the "working" needs?
06:27 PM roycroft: it's pretty well matched to the computer and the version of sw that i'm running
06:27 PM roycroft: and cost me <$200 new
06:27 PM roguish[m]: cool
06:27 PM infornography: oh wow, das cheap, I could buy one for home lol
06:28 PM roycroft: i even splurged and spent $24 on a 4 year extended warranty
06:28 PM roycroft: no questions asked - if i overheat it it's still covered
06:29 PM roycroft: https://www.amazon.com/gp/product/B06X9DWQM6/
06:29 PM _unreal_: infornography, like I said LOOK at the shaft. its solid. no press on collet
06:29 PM _unreal_: This fucker is not powerful but its strong
06:29 PM infornography: We make molds for the fishing industry, small cavities in aluminum and tool steel
06:29 PM roycroft: and it just came way down in price
06:29 PM infornography: kind of want
06:29 PM roycroft: but i'm not surprised - i heard on the news today that the price of gpus is dropping rapidly
06:29 PM _unreal_: infornography, so your looking for high RPM or high torque
06:30 PM roycroft: apparently the supply chain is getting caught up
06:30 PM infornography: RPMs, tiny endmills
06:30 PM _unreal_: infornography, WELL THATS tiny and its gots RPMS
06:30 PM infornography: i see that
06:30 PM infornography: ty
06:30 PM _unreal_: it says 12k rpm but mine runs at 15k
06:31 PM XXCoder: better, and cheaper
06:31 PM _unreal_: 15k native
06:31 PM XXCoder: bah lol
06:31 PM _unreal_: infornography, its ok on aluminum if your doing small stuff.
06:32 PM _unreal_: its NOT worth it if your milling large areas. but small molds might be ideal
06:32 PM _unreal_: especially if your company does 5 axis
06:32 PM t4nk_freenode: a demonstration in the form of a vid would still be nice, before continuing your CLAIM-spree
06:33 PM infornography: we will have one mold a bunch of very small cavities. I get the machine started in the morning and go do something else
06:34 PM _unreal_: and its brushless
06:34 PM _unreal_: only got two points of ware, bits and bearings
06:35 PM _unreal_: wear
06:36 PM _unreal_: infornography, that THAT spindle is one of the only lower power range spindles I could find with a solid shaft
06:36 PM _unreal_: to collet
06:37 PM XXCoder: yea and it has rpm output?
06:37 PM XXCoder: dang nice compared to my $200 spindle lol
06:37 PM XXCoder: $150 plus shipping something
06:37 PM _unreal_: ? what do you have
06:37 PM XXCoder: cheal aliexpress spindle
06:37 PM XXCoder: 27k rpm lol
06:38 PM _unreal_: O,O
06:38 PM XXCoder: its 8 years old now I think
06:38 PM _unreal_: wholy crap
06:38 PM XXCoder: no, 6
06:38 PM _unreal_: :/ well I dont need any spindles I have two that are not even being used
06:38 PM _unreal_: a 1.5kw and a 2.2kw
06:40 PM XXCoder: 800w is what mine is
06:40 PM XXCoder: or was it 400? been way too long
06:43 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/reindeer/reindeer12.jpg
06:43 PM XXCoder: nice
06:44 PM infornography: der
06:44 PM Tom_L: 1/2
06:46 PM _unreal_: Tom_L, I could do that tooooo
06:46 PM _unreal_: prob not as fast
06:46 PM _unreal_: but..
06:47 PM _unreal_: Tom_L, is that 1/4 and 1/8 bits?
06:47 PM Tom_L: i changed it to ballnose the whole thing
06:47 PM t4nk_freenode: Tom_L, so that's to pour chocolate cookies with ey?
06:47 PM Tom_L: .0625
06:47 PM Tom_L: leftover pla
06:47 PM _unreal_: :S in aluminum t4nk_freenode blaaaa
06:47 PM Tom_L: _unreal_, the flat one is a .125
06:48 PM t4nk_freenode: how about alu-cookware... baaaaaaaaaaahhhh
06:49 PM Tom_L: i'll heat it up and brand yer arse with it
06:49 PM t4nk_freenode: lol
06:49 PM infornography: lol
06:49 PM roycroft: i still have some caphlon cookware - anodised aluminium
06:50 PM _unreal_: That is the blower I'm using for my "mini cnc dust collector" https://www.alibaba.com/product-detail/13kpa-air-pressure-and-vacuum-air_60655548498.html?spm=a2756.review-list-buyer.0.0.EHGZCP
06:50 PM roycroft: the pans i use the most i've replaced with le creuset, though
06:50 PM roycroft: which i absolutely love
06:50 PM roycroft: enamelled cast iron
06:50 PM _unreal_: aluminum cookware is just asking for dementia
06:50 PM roycroft: that's a myth
06:51 PM roycroft: and mine is anodised anyway
06:51 PM t4nk_freenode: _unrealia_
06:51 PM roycroft: aluminium oxide is rather inert
06:52 PM roycroft: but anyway, i use the le crueset pans for almost all acidic foods that i cook
06:52 PM _unreal_: roycroft, not a myth at all
06:52 PM roguish[m]: roycroft: le cruesets are truly nice, but way over prices.
06:52 PM t4nk_freenode: I did read some article the other day that aluminium production plants are hazardous and polluting though
06:53 PM _unreal_: roycroft, infact if you use anything acidic it will dissolve aluminum. which goes right into your blood stream. and guess where aluminum likes to deposit. neuro tissue.
06:53 PM roguish[m]: good aluminum pans are hard anodized.
06:54 PM roycroft: like my caphlon pans
06:54 PM _unreal_: use aluminum any kind cookware if you want but your just asking for health problems in your later years. I mean what do I know, I was only a nurse, med tech, I did bio med at one of the world leaders in bio research the Jackson Lab in maine
06:54 PM _unreal_: what do I know
06:55 PM roycroft: you know some stuff about some things, and not much about a lot of things, it seems
06:55 PM t4nk_freenode: _unreal_ has been using the same aluminimim drinking cup for years, and his inglis is better then evur
06:55 PM _unreal_: palm to face PUTER
06:56 PM _unreal_: LOL
06:56 PM roycroft: when cooking in alumium that is not anodized, acidic foods can leach some of the aluminium, but if the cookware is hard anodized, the amount that gets leached is almost unmeasureable
06:56 PM _unreal_: true
06:56 PM _unreal_: though a constant little bit over time is a lot
06:56 PM roycroft: i suppose i could concede that you're correct if one is truly cooking in aluminium
06:57 PM roycroft: but i cook in aluminium oxide
06:57 PM roycroft: it's the exact same thing as those ss pans with the three layer bottoms
06:57 PM _unreal_: raw aluminum is the worst
06:57 PM roycroft: the pan itself is ss
06:57 PM roycroft: but there's a layer of aluminium in the bottom in between two layers of ss, to help distribute the heat evenly
06:57 PM _unreal_: I cook with SS or cast iron
06:58 PM roycroft: those pans contain aluminium, but they would not be considered aluminium pans
06:58 PM _unreal_: roycroft, sounds like a nice set
06:58 PM roycroft: it's the same with hard anodised pans like mine
06:58 PM roguish[m]: raw aluminum oxidizes in seconds....
06:58 PM roycroft: it does, but only a thin layer of it
06:59 PM roguish[m]: self limiting.
06:59 PM roycroft: if you rely on natural oxidation you'll still end up leaching aluminium when you cook acid foods
06:59 PM _unreal_: well I'm going to check out here boys. I did take some video t4nk_freenode dont you worry. I just have to get it off of the tablet, regardless I need to shower and then take my daughter to the super market.
06:59 PM _unreal_: so we can get some budwiser, and hamburger. making TACO's tonight
06:59 PM roycroft: you'll scratch that thin oxide layer off as soon as you start stirring it, and the acid will start leaching the aluminium immediately
06:59 PM roycroft: but anodisation forms a much thicker layer
06:59 PM _unreal_: the budwiser is to mix into the hamburger
07:00 PM Tom_L: _unreal_, you give your daughter bud?
07:00 PM _unreal_: and to mix into the daddy ;)
07:00 PM roycroft: i'll repeat one more time, though
07:00 PM Tom_L: naw that's ok
07:00 PM roycroft: the overhwelming majority of my cooking is done in the le creuset pans
07:00 PM roycroft: which are enameled cast iron
07:00 PM _unreal_: Tom_L, LOL
07:01 PM _unreal_: Tom_L, have you ever used buswiser in hamburger?
07:01 PM Tom_L: nope
07:01 PM _unreal_: its AMAZING
07:01 PM Tom_L: if i had any it wouldn't make it that far
07:01 PM _unreal_: regular buswizer NOT the lite shit
07:01 PM _unreal_: and the TACO beef seasoning
07:02 PM roycroft: the only "regular" budweiser comes from the czech republic
07:02 PM roguish[m]: you're definitely a buttwiper guy.
07:02 PM _unreal_: that is how a lot of mexican resturants cook hamburer
07:02 PM _unreal_: hamburger
07:02 PM roycroft: anything else that calls itself budweiser is shite
07:02 PM _unreal_: I dont drink budwiser
07:02 PM _unreal_: generally
07:03 PM roycroft: i specifically don't drink it
07:04 PM _unreal_: at least we dont have to worry about alcohol abuse
07:04 PM _unreal_: LOL
07:04 PM _unreal_: ehehehehheahahahahahaooooohhahahah
07:04 PM * Tom_L feels roycroft is a cooors guy :)
07:04 PM Tom_L: better yet bussssssh
07:04 PM XXCoder: me, the most hard drink I drink is co2 water
07:04 PM _unreal_: Tom_L, you got to admit that was GOOD
07:04 PM Tom_L: XXCoder, no frozen water
07:05 PM XXCoder: ah true I often add hard water, in form of ice, to my regular water
07:05 PM _unreal_: XXCoder, you didnt
07:05 PM _unreal_: o,O
07:05 PM _unreal_: O,o
07:05 PM XXCoder: ?
07:05 PM _unreal_: I often add hard water, in form of ice, to my regular water
07:06 PM Tom_L: nothin quite like rocky mountain piss water
07:06 PM _unreal_: heh
07:06 PM roycroft: when i'm brewing, which i haven't been for a couple years now, but plan on starting to do again soon, my two house beers are an english bitter and a 60/ scottish ale
07:06 PM _unreal_: I highly reccomend those bits I posted before at this point
07:06 PM roycroft: i don't drink enough to justify brewing for myself
07:07 PM roycroft: and i haven't been visiting/entertaining friends during the pandemic
07:07 PM roycroft: but now that we're moving out of that, it's time to start brewing again
07:07 PM _unreal_: I just ordered 3 more packs.
07:08 PM Tom_L: i usually get coated carbide bits
07:08 PM _unreal_: roycroft, my friend I have not done home brew in like 2 years
07:08 PM _unreal_: killing me
07:08 PM _unreal_: Tom_L, for DIRT cheap THEY are worth there weight
07:08 PM Tom_L: they must not weigh much
07:08 PM _unreal_: doesnt take much gold to amke a lot of $
07:14 PM XXCoder: apparently im in group for group settlement
07:14 PM XXCoder: registered it. doubt I will get a whole lot of money but yeah
07:23 PM _unreal_: ? random... intersting
07:23 PM _unreal_: well I'll be back later maybe. gettting beef beer and prob fantastic beasts to watch tonight.
07:23 PM _unreal_: my daughter and I just finished watching the entire harry potter series
07:24 PM XXCoder: yeah it was random to me too
07:24 PM _unreal_: now onto fantastic beasts 1 and 2 and the one in the theaters
07:24 PM XXCoder: been a while since I last used that service, but it was in applicable range
10:49 PM tcurdt: my mesa 7i92 init led keeps flashing ... any clue what that means?
10:49 PM tcurdt: I can't find anything in the manual about it
10:51 PM Tom_L: ethernet?
10:51 PM Tom_L: maybe it's not finding the ip
10:52 PM tcurdt: not ethernet - the init led
10:52 PM tcurdt: what you mean by "not finding the ip"
10:52 PM Tom_L: does it connect?
10:53 PM tcurdt: haven't tried to ping it yet ... still need to setup the network on the host
10:54 PM Tom_L: so maybe that's the led...
10:54 PM _unreal_: I'm uploading the photos and video right now of the miling job today

11:02 PM CaptHindsight[m]: page #13
11:03 PM tcurdt: so I guess I need to configure the card ... for that I need to find the darn network manager on the linuxcnc base image
11:06 PM Tom_L: typically we set those ethernet cards for or such instead of the standard 192...
11:06 PM Tom_L: then you set up a static ip on the pc in that range
11:06 PM tcurdt: Tom_L yeah, I've set the jumper accordingly
11:07 PM Tom_L: for starters by default i think it is the 192.168.. address
11:07 PM Tom_L: ok
11:07 PM mrec: Tom_L: sorry your link is lost in the history here again, can you give me the url to the modbus info which you have?
11:08 PM mrec: I have also received some modbus details from the vendor
11:08 PM Tom_L: no
11:08 PM Tom_L: :)\
11:08 PM mrec: I'll check if the files are the same, if not I'll send you the stuff
11:08 PM Tom_L: see if it's there

11:11 PM mrec: Tom_L: can you give me your mail? I can send it
11:12 PM Tom_L: maybe tomorrow.. i'm trying to get something done here then sleep
11:12 PM mrec: well just give me your email and I'll send the zip packages to you
11:12 PM mrec: I'll upload it to my server and give you the link

11:36 PM tcurdt: Tom_L CaptHindsight[m] I can now read the config from the card ... but it's still blinking
11:40 PM tcurdt: this looks OK to me https://gist.github.com/tcurdt/79a8e81e7e000afbb52f7b1d34aaa099
11:41 PM Tom_L: yup
11:42 PM Tom_L: has no bit file loaded
11:42 PM Tom_L: i thought he usually loaded one by default
11:43 PM tcurdt: so that's normal as it flashes as in "not configured"
11:43 PM Tom_L: i dunno
11:43 PM Tom_L: i'd have to dig out the manual
11:46 PM tcurdt: "If this happens it means the user configuration is corrupted or not a proper configuration for the 7I92s FPGA. This can be fixed by running the configuration utility and re-writing the user configuration"
11:46 PM tcurdt: Is the default configuration somewhere?
11:46 PM tcurdt: so I could try to flash that?
11:46 PM Tom_L: i'd wait for morning and ask pcw--home
11:47 PM Tom_L: he's West coast time
11:47 PM Tom_L: and i'm heading to sleep
11:47 PM Tom_L: don't screw up the backup config
11:48 PM tcurdt: I should also be asleep .. I just wanted to try ... *hours later*
11:48 PM Tom_L: lest you have to send it back to get flashed again :)
11:48 PM tcurdt: yeah .... probably better to do this when not tired
11:49 PM tcurdt: a little surprised you can actually brick the cards like that
11:49 PM Tom_L: it has a recover config
11:49 PM Tom_L: but if you botch it too then you're screwed
11:49 PM tcurdt: but even then ... why can't I flash the card?
11:49 PM Tom_L: do you have a jtag?
11:49 PM tcurdt: sure
11:50 PM Tom_L: then you probably can
