05:05 AM JT-Cave: morning
05:19 AM JT-Cave: Lcvette[m], yes that is a limitation of the current version of mesact
05:35 AM * Mangy_Dog sniffs about
05:38 AM jpa-: we smell of way oil and burned endmills
05:39 AM Mangy_Dog: :D
05:40 AM Mangy_Dog: nice to see so many familuar faces here
05:40 AM Mangy_Dog: im going to be doing a printNC this year
05:41 AM Mangy_Dog: need a ncie cnc machine for a bunch of projects i want to do
05:43 AM jpa-: printnc definitely has nice documentation
05:44 AM Mangy_Dog: its also affordable for me, robust and frankly.. better than most of the openbuilds ive seen
05:45 AM Mangy_Dog: sorry any openbuilds enthusiasts
05:45 AM Guest47: Hello, I need some help. I've installed linuxcnc via apt in buster, but it cannot find glade in path when I do linuxcnc_info
05:47 AM jpa-: Mangy_Dog: if you have the space, i would suggest planning to have some kind of enclosure / cabinet for the machine - it really cuts down on the noise and dust, and often it is easier to do if you plan for it already before building the machine
05:47 AM Mangy_Dog: oh i plan o
05:47 AM Guest47: previously I tried installing linuxcnc distro with the iso file (version 2.8.4), but it hanged at "configure network". That's why I went installing buster first and then linuxcnc as documented in the documents via apt
05:47 AM Mangy_Dog: to
05:47 AM Mangy_Dog: also going to concrete level a base for it to stand on
05:48 AM Mangy_Dog: but theres a few nasty things i got to deal with this year first
05:48 AM Mangy_Dog: dads cancer, and a house move
05:48 AM Mangy_Dog: ill be buying the kit bits soon
05:48 AM Mangy_Dog: but wont be building till after the move and i know exsactly whats happening
05:51 AM Mangy_Dog: and yes will be making an enclosure around it
05:51 AM Mangy_Dog: maybe coriogated PC or something foam based for noise
05:54 AM jpa-: i used some old office wall divider elements for the back walls and two layers of polycarbonate for door on mine https://raw.githubusercontent.com/HacklabJKL/sergei_cnc2/main/photos/cabinet_2022_06.jpg
05:57 AM Mangy_Dog: ohhh nice :D
05:58 AM jpa-: it seems to be quite effective, though the wall elements are not necessarily the easiest to keep clean
05:58 AM Mangy_Dog: nodnods
05:58 AM Mangy_Dog: oh btw
05:59 AM Mangy_Dog: one of the things i want to do with the printNC... is print the new parts i need to fix my rodcoregotrailed
05:59 AM Mangy_Dog: :p
05:59 AM Mangy_Dog: the railcore thing i did years ago
05:59 AM rmu: Guest47: what is your problem?
06:04 AM Guest47: my problem is I want to develop a glade application, but it doesn show glade in path (doing linuxcnc_info)
06:04 AM rmu: did you install glade?
06:05 AM Guest47: that's the thing, I haven't found any way to install glade-gtk2
06:05 AM Guest47: if I do> apt instal glade I get version glade 22
06:07 AM Guest47: if I do apt install glade-gtk2, ok install, but still not found linuxcnc_info
06:09 AM rmu: sorry can't help there. gtk2 is legacy stuff. if you don't have a good reason to use it i would suggest looking for alternatives.
06:10 AM Guest47: ok, so how to develop a glade app for the axis gui?
06:10 AM Guest47: by the way, gladevcp_demo fails if I try it
06:10 AM rmu: https://forum.linuxcnc.org/48-gladevcp/44890-gtk3-gladevcp-catalog
06:11 AM Guest47: thanks
06:11 AM rmu: if it is new stuff I would probably bite the bullet, use 2.9 pre with gtk3 and python3
06:12 AM Guest47: it sound great for me. I will have a shot with it
06:14 AM Guest47: also, do you have any idea why linuxcnc-buster-2.8.4.iso hangs at "configure network" ?
06:14 AM Guest47: just out of curiosity
06:14 AM rmu: also look at qtvcp in linuxcnc 2.9
06:14 AM rmu: no idea
06:14 AM Guest47: debian buster iso install with no problem
06:15 AM Mangy_Dog: whats the recommended spec for linuxcnc for some of the nicer control uis?
06:16 AM Mangy_Dog: im assuming a 1ghz celeron dual core wouldnt cut it
06:17 AM Mangy_Dog: https://www.ebay.co.uk/itm/255815547449 how about this?
06:27 AM jpa-: Mangy_Dog: what kind of hardware interface will you use?
06:27 AM jpa-: parallel port or something more advanced?
06:33 AM jpa-: with parallel port, you can expect one of the cores be mostly taken up by the realtime stuff
06:35 AM jpa-: as a rule of thumb, if it can run youtube with a modern browser with good latency-test results, it is fast enough for linuxcnc GUIs also :)
06:35 AM * travis_farmer[m] decides he may as well head out to the shop and get it warmed up...
06:39 AM Mangy_Dog: im assuming usb
06:40 AM Mangy_Dog: the controller will be a gerber hal thingy or flexihal
06:40 AM Mangy_Dog: not sure
06:45 AM Rowow[m] is now known as Rowow5457[m]
06:48 AM jpa-: Mangy_Dog: oh? so not going to use linuxcnc?
06:48 AM Mangy_Dog: i thought i was?
06:48 AM Mangy_Dog: is linux cnc only for paralell controllers?
06:49 AM jpa-: AFAIK grblhal does its own motion control on the microcontroller, while linuxcnc does it on pc
06:49 AM Mangy_Dog: oh i thought linux cnc worked as an interface for that oo
06:49 AM Mangy_Dog: too
06:50 AM Mangy_Dog: the thing is... I simply cant get hold of paralell computers any more
06:50 AM jpa-: looks like for flexihal they optionally run linuxcnc on raspberry pi
06:50 AM Mangy_Dog: ive got a spare pi
06:50 AM jpa-: you can buy parallel port cards for pci or pcie, or you can get a mesa card if you can get hold of one
06:50 AM Mangy_Dog: that would save me money :D
06:51 AM Mangy_Dog: i dont know the interface design so much... but is the paralell port simply motor on off and directions being set on the pins?
06:51 AM Mangy_Dog: rather than actual data being sent?
06:52 AM jpa-: typically step & direction
06:52 AM Mangy_Dog: hah
06:52 AM jpa-: for more advanced machines you have position feedback
06:52 AM Mangy_Dog: ohh
06:52 AM Mangy_Dog: i had wondered if i should bother with feed back servos/steppers
06:53 AM jpa-: nice thing about servos is that a lot of time the controller will neatly stop when things go terribly wrong
06:53 AM jpa-: whereas a stepper based machine will keep making things worse until you come to stop it
06:53 AM jpa-: though some newer stepper drivers have lost step detection
06:53 AM Mangy_Dog: oops
06:59 AM rmu: depending on server controller / system, IMO servos are more dangerous than steppers, servos can run away if there is a problem with feedback
07:02 AM jpa-: that's true also
07:02 AM jpa-: i made this https://www.forum.linuxcnc.org/24-hal-components/46092-hal-component-for-dc-motor-runaway-protection after my first scare with disconnected feedback cable :D
07:04 AM rmu: keep estop close
07:22 AM travis_farmer[m]: odd issue, i can activate my machine, no issues, but the instant i try to jog an axis, the machine ESTOP trips for some reason. i don't think there is anything to trip the estop, that i am aware of...
07:24 AM jpa-: travis_farmer[m]: try halscope on the estop pin
07:24 AM jpa-: i had some EMI noise so strong that it caused pulses on unshielded estop switch cable
07:24 AM jpa-: because it had only the weak pull-up
07:24 AM sensille: same here
07:24 AM travis_farmer[m]: just solved it... idiot error, forgot to connect the HAL pin to enable the stepgen
07:25 AM sensille: switched to inm module on the fpga card
10:14 AM roycroft: yay - nail gun depot finally have composite nail guns back in stock
10:25 AM roycroft: i wonder how long the composite nails will keep
10:25 AM roycroft: since they're plastic, they might become brittle over time
10:25 AM roycroft: and they are somewhat expensive
10:25 AM roycroft: i guess i'll find out
10:31 AM roguish[m]: roycroft: store 'em like you store yout 3d print fillament
10:38 AM roycroft: i'll see if there's a recommended way to store them
10:38 AM roycroft: i ordered three lengths of nails, and there are 2000 to a box, so that should last me quite a long time
10:39 AM Tom_L: framing nailer or other?
10:39 AM roycroft: but you know, when i say they're expensive, a box of those nails costs less than a good router cutter
10:39 AM roycroft: no, a composite nailer
10:39 AM roycroft: it shoots 15ga plastic nails
10:39 AM roguish[m]: just curious. why composite nails?
10:39 AM roycroft: for hold downs on the cnc router
10:39 AM roycroft: so i don't have to worry about clipping a nail with the cutter
10:40 AM Tom_L: cutter should trump nail anyway
10:40 AM roguish[m]: ah, ok. sorta makes sense....
10:40 AM roycroft: and when i'm making jigs, i won't even have to worry about leaving tabs on the piece
10:40 AM roycroft: i can just shoot nails through the waste and the part
10:41 AM roycroft: it lets me be lazy and confident that my parts won't go flying around
10:41 AM roycroft: it seems an ideal solution for holding things down on a cnc router
10:41 AM Tom_L: possibly
10:42 AM Tom_L: i'm not fully convinced
10:42 AM roycroft: well, i'll find out at some point in the not too distant future
11:26 AM JT-Cave: https://www.youtube.com/watch?v=oXg4eScFL3I
11:29 AM bjorkintosh: ah wood. I don't know why I immediately think of metal when I hear or see "CNC"
11:30 AM c101horse8332[m]: whohooo
11:30 AM c101horse8332[m]: the pi moves the mill
11:30 AM bjorkintosh: good job!
11:30 AM c101horse8332[m]: its not yet go time tho
11:31 AM roycroft: yeah, that video is what i'm talking about, and what i expect
11:31 AM bjorkintosh: c101horse8332[m], was it worth the frustrations and head banging then?
11:31 AM roycroft: bjorkintosh: i'm careful not to just say "cnc" - i always say "cnc router", "cnc lathe", "cnc mill", etc.
11:32 AM roycroft: and i should hope that "cnc router" does not making thinking shift to exclusively metal
11:32 AM roycroft: or even default to metal
11:32 AM c101horse8332[m]: when i start the machine and start jogging itll move a little bit and then throw a following error, turn the machine back on on the screen and you can jog it in a direction, but if you try to jog in the oposite direction on the axis you were jogging in itll throw a following error
11:32 AM c101horse8332[m]: does this in all axis
11:34 AM c101horse8332[m]: could one or more of you maybe take a look at my ini file and see if you see anything that could be causing it?
11:35 AM bjorkintosh: where's said ini file?
11:35 AM bjorkintosh: also, is it throwing more errors than the one you mentioned?
11:39 AM * c101horse8332[m] posted a file: (4KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/CEfmwjNSNGqBMciNZenWZMFt/frees.ini >
11:48 AM JT-Shop__ is now known as JT-Shop
11:48 AM * JT-Shop goes to work for a bit
12:08 PM Rab: <roguish[m]> just curious. why composite nails? <roycroft> so i don't have to worry about clipping a nail with the cutter
12:09 PM roguish[m]: yeah, I saw that
12:09 PM Rab: It seems that composite nails are a glass-fiber bearing plastic, so I'm not sure they're great for cutters either.
12:10 PM Rab: But maybe they're less likely to break the cutter, if that's the concern.
12:10 PM Tom_L: Fr4 is quite abrasive and in a similar class as the nails
12:10 PM Rab: Yeah, I have done quite a bit of PCB drilling and routing and it's tough even on carbide.
12:12 PM roycroft: they're a nylon composite
12:15 PM roycroft: the biggest drawback that i've seen discussed is that they don't penetrate thick hardwoods, and require pre-drilling for that application
12:15 PM roycroft: my intended use will be almost exclusively to hold down mdf and plywood, so that shoudn't be an issue for me
12:16 PM roguish[m]: fibreglass is rough as hell on blades...... a friend pretty much destroyed a good carbide table saw blade of mine cutting some thin fibreglass sheets.
12:20 PM CloudEvil: For the occasional one, it's less of an issue.
12:20 PM CloudEvil: I wonder if copper might actually be better
12:26 PM * c101horse8332[m] uploaded a video: (8474KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/MokGWYxwXNfhWGdMclGeNCzp/VID_20230210_191346.mp4 >
12:26 PM c101horse8332[m]: Whohoo movement
12:29 PM bjorkintosh: congratulations c101horse8332[m]
12:31 PM c101horse8332[m]: im reading through the qtdragon docs, trying to find what the reason might be that when i click on the 'go home' button the Z-axis starts going home and then stops again
12:32 PM zephyr9900: Tom_L not quite right but It might just work https://photos.app.goo.gl/axruYgw2nJBsHgj89
12:32 PM c101horse8332[m]: i have to click go home a couple times before the z is at its home point and the other axis start moving also going so far before stopping again
01:15 PM roycroft: ok, i had to do some digging, and i found that while the product description for the nails i'm getting say they're a nylon composite, the manufacturer's site says they're a polymer fiberglass composite
01:15 PM roycroft: they may nick hss cutters, but should be perfectly fine with carbide cutters, which is all i'll be using on the cnc router
01:34 PM CloudEvil: I would want to see a test of a cutter doing (say) a surfacing run of a sheet till it's blunt and compare one stuck down with hotmelt or whatever to these.
01:39 PM roycroft: that might be an interesting experiment
01:48 PM Rab: "Nylon composite" and "polymer fiberglass composite" are compatible descriptions, of course. Glass-filled nylon is a pretty standard thing for a lot of applications.
01:49 PM roycroft: yeah, but the vendor description failed to mention the fiberglass part
01:50 PM Rab: I've found glass-filled nylon fasteners to perform somewhat better than plain nylon, which are close to wet noodles at room temperature.
01:50 PM roycroft: i still think this will be a good solution
01:50 PM roycroft: and it might also work well for outdoor projects
01:50 PM roycroft: steel/galvanized nails will rust and bleed over time
01:50 PM roycroft: ss nails are expensive
01:51 PM roycroft: composite nails might be the good solution for that
01:54 PM Rab: I feel like Ace Hardware is mistaken in their description here. https://www.acehardware.com/departments/tools/fastening-tools/power-tool-nails/2850410
01:54 PM XXCoder: Mangy_Dog: whats you building?
01:54 PM Mangy_Dog: will be doing a printNC
01:56 PM XXCoder: ah interesting. for wood and plastic?
01:56 PM XXCoder: if you wanted a mill theres also millenium machining mill
01:59 PM Mangy_Dog: alu mostly actually :D
02:00 PM XXCoder: ok
02:01 PM roycroft: mistaken?
02:01 PM roycroft: you think they are not "made of high quality material"?
02:01 PM roycroft: and you think they are not made of "metal"?
02:02 PM Rab: The material is very possibly high quality metal of some type, I just don't think it's aluminum.
02:02 PM roycroft: they did not say it is
02:03 PM roycroft: they say it's made out of "metal"
02:03 PM roycroft: the finish is "aluminum"
02:03 PM roycroft: i think there's about a 100% chance they're made out of pot metal that is mostly iron
02:04 PM Rab: "luxurious faux aluminum look"
02:07 PM * JT-Woodshop calls it the weekend has arrived
02:11 PM Mangy_Dog: printNC is built from steel box section :D
02:11 PM Mangy_Dog: ball screws rails its SOLID
02:11 PM Mangy_Dog: is capable of cutting steel
02:11 PM Mangy_Dog: though i plan to only do alu
02:11 PM XXCoder: wonder what BOM would be like
02:12 PM Mangy_Dog: the kit part is about £800 steel about 80 quid... plus about 500 quid worth other bits
02:28 PM c101horse8332[m]: dang, for some reason the qt dragon probing doesnt do the z height first
02:29 PM XXCoder: interesting mangy
02:38 PM * JT[m] uploaded an image: (299KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/UPGNKKJqZWdMUoLKCwcPWQYw/20230210_143754.jpg >
02:39 PM CaptHindsight[m]: https://wiki.printnc.info/en/home
02:41 PM CaptHindsight[m]: "The PrintNC is a high performance, DIY CNC router. " :)
02:42 PM CaptHindsight[m]: "Steel tubes dimension
02:42 PM CaptHindsight[m]: The default choice is 75mm x 50mm x 3mm (3" x 2" x 0.12") Hot or Cold Rolled Steel Tubing (e.g. A513)."
02:44 PM XXCoder: jt nice
02:46 PM JT-Woodshop: thanks
02:48 PM XXCoder: in least screws look proper diameter
02:48 PM XXCoder: I saw one guy building much bigger router, and use thinner ballscrews lol
02:48 PM XXCoder: could easily see it whup around as it moved
02:50 PM Loetmichel: CaptainHindsight: ANYTHING that has "print" and "router/mill" in the name cant be good.
02:51 PM XXCoder: Loetmichel: millenium is interesting one, it uses bunch of printed parts, but goal is to mill alum to replace most of those
02:52 PM XXCoder: its sort of bootstrapping using easily bought parts and 3d printer
02:52 PM XXCoder: then you can make missing parts and replace printed structural parts
02:53 PM XXCoder: some dont bother with replacing parts, depending on what their needs is
02:54 PM XXCoder: ie one planning wood cutting only dont plan to replace those parts
02:59 PM Tom_L: zephyr9900, cool
03:00 PM XXCoder: hmm
03:00 PM XXCoder: whats it making?
03:00 PM XXCoder: initially thought spring but then no
03:01 PM Tom_L: JT-Woodshop, lookin good
03:02 PM zephyr9900: Tom_L thanks for helping me find the music wire.
03:03 PM XXCoder: zephyr9900: whats that thing used for?
03:03 PM Tom_L: np
03:04 PM zephyr9900: 1978 Honda XL175 kick start return spring that I can't buy
03:04 PM XXCoder: ahh different kind of spring?
03:04 PM zephyr9900: torsion
03:04 PM XXCoder: better word yes
03:05 PM XXCoder: interesting indeed.
03:07 PM zephyr9900: I used G33 z0.64 K0.106 G33 z0.001 k0.001 G33 z0.106 K0.106
03:07 PM JT-Woodshop: Tom_L, thanks
03:08 PM Tom_L: will be interesting to see the pattern that emerges
03:08 PM Tom_L: zephyr9900, on the crossover maybe turn it by hand and guide the wire
03:09 PM zephyr9900: I think the mandrel should have a thread to keep the wire in place for the first layer but i will only do that if this one does not work
03:11 PM zephyr9900: I have plenty of extra wire :-)
03:11 PM Tom_L: yup
03:14 PM roguish[m]: hey, has anyone heard of these guys????? https://www.shopsabre.com/
03:23 PM XXCoder: buy second machine for first time?
03:24 PM XXCoder: quote required
03:25 PM roguish[m]: just met a friend of a friend who bought one....
03:35 PM JT-Woodshop: hmm the little one is only $9,500
03:35 PM XXCoder: you got a quote?
03:36 PM JT-Woodshop: scrolled down to the price
03:36 PM roguish[m]: doesn't say anything about the software, but the images look windows.
03:37 PM roguish[m]: this guy bought the small one, and a 4th axis. he's a retired software dude.
03:38 PM roguish[m]: lots of money, setting up a retirement fun wood shop.
03:38 PM JT-Woodshop: sounds fun
03:38 PM JT-Woodshop: I should retire...
03:39 PM XXCoder: ah finally found the small one
03:39 PM roguish[m]: JT-Woodshop: are you gonna get one of the new electric vettes?
03:39 PM roguish[m]: supposed to be scary fast
03:39 PM XXCoder: high acceration or high max speed?
03:39 PM roguish[m]: yes
03:39 PM JT-Woodshop: no, I looked at them but just want the coupe
03:39 PM JT-Woodshop: yup
03:40 PM JT-Woodshop: 0-60 2.5 seconds
03:40 PM JT-Woodshop: I can live with 0-60 2.9 seconds
03:40 PM roguish[m]: pooper
03:40 PM XXCoder: lol ill just keep driving my ford focus
03:40 PM XXCoder: when I can drive :P
03:40 PM JT-Woodshop: you get one and we'll run on the track
03:41 PM roguish[m]: i wish
03:43 PM * JT-Woodshop watches another Leo video
03:44 PM roguish[m]: news. looks like just shot down another balloon. over alaska
03:45 PM roguish[m]: 'high altitude object'
03:47 PM CloudEvil: It's actually delayed reporting from late December.
03:48 PM roguish[m]: doesn't say that... https://www.bbc.com/news/world-us-canada-64605447
03:49 PM roycroft: it's all a bunch of hooey
03:50 PM roycroft: right wing morons with no understanding of anything begging for excuses to get triggered
03:51 PM roguish[m]: roycroft: have you seen ShopSabre stuff?
03:51 PM roguish[m]: link way above....
03:51 PM roycroft: i hadn't until just now
03:51 PM roycroft: it looks like pretty sturdy stuff
03:51 PM roycroft: a bit too rich for my pocketbook though
03:51 PM roguish[m]: just wondering.
03:51 PM XXCoder: it'd be good for small commerical I guess, since its a product with warranities and insurable
03:52 PM XXCoder: I probably can build as large for couple thousand usd
03:52 PM XXCoder: but no warranty and doubt insurers would cover it
03:56 PM roycroft: dictionary.com's word of the day is "nomophobia", which means "anxiety caused by being without acces to a functioning mobile phone"
03:57 PM roycroft: does that mean that i have antinomophobia?
04:00 PM XXCoder: lol
04:00 PM XXCoder: i wonder what wiord is best for second part, for not caring to have or not have
04:00 PM XXCoder: nomodontcare ;)
04:01 PM roycroft: i feel somewhat anxious when i am around a functioning mobile phone
04:01 PM roycroft: it means someone may say or do something stupid
04:21 PM JT-Woodshop: last ring glued up
04:21 PM JT-Woodshop: back to Sampson Boat Co video
04:22 PM Tom_L: tomorrow turning day?
04:22 PM JT-Woodshop: maybe some on Sunday, just gluing the ring half's together
04:38 PM XXCoder: LOL https://www.reddit.com/r/Machinists/comments/10z4h08/i_thought_some_of_you_would_appreciate_this_3d/
04:39 PM XXCoder: great idea for keyboard only cnc machines?

04:49 PM XXCoder: I see that company is also operated by cats
04:49 PM Tom_L: more toys
04:49 PM JT-Woodshop: dang box is 10 times the size of the item
04:50 PM Tom_L: it's part of the box delivery contract. they fill their truck up and when it's empty they can go home
04:50 PM XXCoder: no no cats makes more sense ;)
08:31 PM _unreal_: so its nice having the ender
