01:35 AM Deejay: moin
04:06 AM Tom_L: morning
04:06 AM XXCoder: o/
04:58 AM JT-Cave: morning
04:58 AM XXCoder: o/
07:40 AM JT-Cave: yea it's Wednesday... bacon and egg day
08:11 AM unterhaus: I think they are taking Ida a little too seriously around here
08:11 AM unterhaus: just got a "do not attempt to travel" warning
08:11 AM unterhaus: there are no places that flood around here that I have to travel through
08:17 AM JT-Cave: lol
08:34 AM rs[m]: unterhaus: maybe that is meant in a yoda "there is no try" kind of way.
08:35 AM unterhaus: I have a friend who normally commutes through a place that floods every time we have heavy rain like this. But I'm pretty sure he has alternate routes.
08:36 AM unterhaus: Not sure if they canceled school for his kids though
08:37 AM unterhaus: the township told us to secure our trash cans. Highest windspeed predicted for today is 11mph. That's not even a normal spring day around here
08:52 AM basilic_ is now known as Basilic
09:06 AM perry_j1987: morning
09:07 AM jepler[m]: We're visiting Boston and it sounds like it'll get pretty wet for the next 36h
09:36 AM perry_j1987: was a bit of a cold ride back from the shop last night, temp dropped
10:11 AM JT-Shop: I've always wanted to eat at the Boston Burger Company
10:25 AM roycroft: i ate at the union oyster house in boston once
10:26 AM roycroft: it's the oldest continuously-operated restaurant in america
10:26 AM perry_j1987: i've never been to the east coast yet
10:27 AM roycroft: i haven't left the pacific timezone in ages - like 15 years or more, but i grew up back east, and have been to every state east of the mississippi
10:28 AM perry_j1987: im originally from wa
10:28 AM roycroft: it's actually been almost 20 years, now that i think about it
10:28 AM roycroft: i was in new york a week before the 9/11 attack, and that was both the last time i flew and the last time i left my timezone
10:29 AM roycroft: my trips these days are northerly/southerly
10:29 AM roycroft: where in washington are you from?
10:30 AM perry_j1987: born in eastern side and grew up all across western side
10:30 AM roycroft: aah
10:30 AM roycroft: i lived in bellingham before i moved down to eugene
10:30 AM perry_j1987: what took you to oregon
10:30 AM roycroft: the oregon coast
10:30 AM roycroft: it wa a 5 hour drive from bellingham
10:30 AM roycroft: it's an hour from eugene
10:31 AM perry_j1987: aye the coast is nice
10:31 AM roycroft: and if i find the right place, i'd like to move to the coast some day
10:31 AM perry_j1987: being in bellingham has its benefits too
10:31 AM roycroft: yes, i loved bellingham
10:31 AM roycroft: i lived right by the bay - i could see lummi island and the san juans from my house
10:31 AM roycroft: and it was a quick drive to vancouver
10:31 AM perry_j1987: aye
10:32 AM roycroft: i've been to more concerts in vancouver than seattle
10:32 AM perry_j1987: heh
10:32 AM perry_j1987: i've still been to more in seattle and i havnt lived in wa since 2005
10:35 AM roycroft: i've probably been to more concerts in chicago than anywhere else, but i'm not sure
10:36 AM roycroft: i lived right in the city, and went to shows all the time, but i only lived there for a few years while old enough to be attending concerts and the like
10:36 AM roycroft: i started going to chicago symphony concerts when i was about 10
10:37 AM roycroft: lyric opera when i was 12 or 13
10:37 AM roycroft: so i got a early start on that stuff
10:37 AM perry_j1987: i'd like to see that some day
10:37 AM perry_j1987: my buddy's mom was an opera singer in chicago back in the day
10:39 AM roycroft: one of my high school classmates is a famous opera singer - dawn upshaw
10:39 AM roycroft: her older sister was actually in my grade, but i knew dawn
10:40 AM roycroft: she was an amazing singer even in high school
10:48 AM roycroft: hmm
10:48 AM roycroft: ups have detailed tracking information available again
10:48 AM roycroft: that's nice
10:48 AM roycroft: it takes a couple extra clicks to display it, but at least it's back
10:53 AM roycroft: so i am making progress on my router design, but i'm still uncertain about the y axis drive, which will move the gantry
10:53 AM roycroft: the lowrider, on which i'm basing my router, uses a belt drive for the y axis
10:54 AM perry_j1987: rack n pinion or belt?
10:54 AM roycroft: my 3d printer is belt drive, but it's also really light weight, and not particularly accurate compared to standard subtractive machining gear
10:54 AM perry_j1987: leadscrews that long i imagine would have some nice whip to them
10:54 AM roycroft: belt
10:54 AM roycroft: toothed belt
10:54 AM roycroft: my expectation is that i can hold 0.005" or so with the router
10:54 AM perry_j1987: people are cutting alum with belts on shapokos and such
10:55 AM perry_j1987: how big of router
10:55 AM roycroft: is that unreasonable with a belt drive?
10:55 AM roycroft: i'll use a 3hp 80mm spindle motor
10:55 AM perry_j1987: what table size
10:55 AM roycroft: the ubiquitous style that all the cnc router folks use
10:56 AM roycroft: i want to be able to machine 2'x4' sheet goods, so about 38" wide by 60" long is what i'm working with right now
10:56 AM perry_j1987: if it's big 4x8 i'd first look into rack n pinion
10:57 AM perry_j1987: are you doing a budget build or an all out build
10:57 AM roycroft: this is the major criterion for the design: it needs to sit on top of my router table, and be able to be installed/removed very quickly
10:57 AM roycroft: it can't be a a permanent installation
10:57 AM roycroft: in between budget and all out build
10:57 AM roycroft: i want to do it right
10:58 AM roycroft: but i don't need high speed production capability
10:58 AM roycroft: i do not plan on making finished parts with it, at least not primarily
10:58 AM roycroft: my primary use will be making jigs and fixtures that will be used to make production parts
10:58 AM roycroft: so i can easily sacrifice speed for accuracy and for keeping the budget down
10:59 AM roycroft: my plan is to make some rails that bolt onto the sides of the router table
10:59 AM perry_j1987: you could use a projector mounted to the ceiling of your shop to project your sketches or dxf plans onto the wood and trace :)
11:00 AM perry_j1987: if you like working with your hands and wood etc
11:00 AM roycroft: did you see my pictures of the greene and greene style drawer pulls i recently made?
11:00 AM perry_j1987: no
11:01 AM roycroft: https://roycroft.us/Drawer-Pulls
11:01 AM roycroft: i had to make a couple jigs to get the front curves righ
11:01 AM roycroft: t
11:02 AM roycroft: and while the wider pulls look good, the narrower ones could have used a bit more curvature
11:02 AM roycroft: that project is what made me decide i need a cnc router
11:02 AM roycroft: it took a while to make the jigs
11:03 AM perry_j1987: nice
11:03 AM perry_j1987: 3d printers make great jig makers too
11:03 AM roycroft: and i'd liked to have made a custom jig for each size pull, but since making the jigs was a fair amount of work, i used the same ones for all of them
11:03 AM roycroft: i've used my 3d printer for that, and it works ok, but not great
11:03 AM perry_j1987: take your object and draw a box around it and combind subtract
11:04 AM roycroft: but i could not have used it for these - the jigs are way larger than my printer can handle
11:04 AM roycroft: i really need to be able to route them out of mdf
11:04 AM perry_j1987: you can print in pieces that dovetail together etc
11:04 AM roycroft: that would also take way too long with the 3d printer
11:04 AM perry_j1987: or print cradles that you space apart screwed to wood etc
11:04 AM roycroft: hours or tens of hours vs. a couple minutes with the cnc router
11:05 AM perry_j1987: aye
11:05 AM roycroft: another application that is important is bending forms
11:05 AM roycroft: i have a vacuum veneering system
11:05 AM roycroft: big nylon bag and vacuum pump
11:05 AM roycroft: if i want to make some curved pieces i need to make forms to bend around
11:06 AM roycroft: which is usually a number of identical curves cut on some mdf sheets that are glued together to make a form
11:06 AM roycroft: a bit tedious to do by hand, but exactly what a cnc router excels at doing
11:06 AM perry_j1987: aye
11:06 AM roycroft: the justification for the router is easy
11:06 AM perry_j1987: aye
11:07 AM perry_j1987: all to easy lol
11:07 AM roycroft: the problem is that i don't have room for one, which is why this lowrider design is interesting
11:07 AM perry_j1987: maslow cnc heh
11:07 AM perry_j1987: hang one on your wall
11:07 AM roycroft: if i can detatch the gantry easily and detatch the y axis rails easily, i'll have a router that comes apart in 3 pieces
11:08 AM roycroft: those, plus a spoil board, will be easy to store
11:08 AM roycroft: and i can use the same linuxcnc computer that i've built for my mill
11:08 AM perry_j1987: *snickers - it def will hold 0.005 tollerance
11:08 AM roycroft: i looked at the maslow cnc design when i first got interested in a cnc router
11:09 AM roycroft: i don't want to go that way at all
11:09 AM roycroft: and it still would not be compact enough for me
11:09 AM roycroft: i have no wall space to hang it on
11:09 AM perry_j1987: you just build a maslow and then add a 3000+ router to it haha https://www.rockler.com/shaper-origin-handheld-cnc-router?country=US&sid=V91040&promo=shopping&utm_source=google&utm_medium=cpc&utm_term=&utm_content=&utm_campaign=PL&gclid=CjwKCAjwybyJBhBwEiwAvz4G7wiFraVom5Qe17T20bTxDMpfIYWot1wwXdD2Kijnl0SFYNmHOBQahRoC9dsQAvD_BwE
11:09 AM roycroft: i do have some space to hang some pieces from my rafters
11:10 AM roycroft: i'm not going to spend $2500+ on a shaper origin
11:10 AM perry_j1987: haha
11:10 AM roycroft: the shaper origin is actually an interesting device
11:10 AM roycroft: but for me, i don't want a cnc machine that i have to manually operate
11:11 AM perry_j1987: its something i imagine seeing a sketch for in popular mechanics showing woodworking in the future
11:11 AM roycroft: i want to set up the job, press the go button, and have it do the work on its own while i do other things
11:11 AM perry_j1987: futuristic spin on an old way of doing things etc
11:11 AM roycroft: the purpose of the cnc router is to save time
11:11 AM perry_j1987: i still stand there watching the thing the whole time
11:11 AM roycroft: i can get the accuracy i need making the parts manually
11:11 AM roycroft: it just takes a long time
11:11 AM perry_j1987: fascination lol
11:12 AM perry_j1987: so you want an accurate cnc router thats dissassembleable?
11:12 AM roycroft: yes
11:12 AM perry_j1987: why not a perm built one that you raise to the ceiling and lower it onto your router table bench
11:12 AM roycroft: and i really don't want to have to spend more than 10 minutes setting it up
11:12 AM roycroft: the ceiling is not high enough
11:13 AM roycroft: the gantry is perpendicular to the rails
11:13 AM roycroft: as it has to be
11:13 AM roycroft: if i can index the rail mounts accurately the setup should be pretty repeatable
11:13 AM JT-Shop: while it's overcast and only 25°C I'm going to do some outdoor projects
11:13 AM perry_j1987: time for a second shop? :)
11:16 AM roycroft: i like the idea of a router that i can set up/take down quickly and easily
11:17 AM roycroft: the lowrider controller software has autolevelling capability for the y axis, but assumes that x is pretty straight
11:17 AM roycroft: i know linuxcnc has autolevelling capability, and i should think that i can get that working for a router
11:26 AM JT-Shop: that seems to be putting the cart before the horse so to speak
11:33 AM roycroft: how so?
12:01 PM JT-Cave: you have not built the router yet
12:05 PM roycroft: oh, sure
12:06 PM roycroft: i'm still in the design phase, but i need to anticipate how i'll operate the router while designing it
12:07 PM roycroft: when i built my router table i installed some soss hinges on the top, so i could open it up to access the inside when needed
12:08 PM roycroft: that will come in handy when i build the cnc router, as i'll be able to easily remove the top of the router table completely and install some indexing pins on the underside for mounting the cnc router rails
12:25 PM enleth: how does one use a 5-fluted adjustable reamer?
12:26 PM enleth: https://i.imgur.com/UPM78bC.jpg
12:27 PM enleth: this thing
12:27 PM JT-Shop: very painfully
12:27 PM enleth: I've got a bunch of those, different sizes, same design
12:27 PM JT-Shop: I have a whole set of them
12:27 PM enleth: how is this supposed to be measured?
12:28 PM JT-Shop: ring gauge
12:28 PM * JT-Shop goes to mow before it rains
12:30 PM roycroft: the good ones are very fiddly, enleth
12:30 PM roycroft: most of them are completely useless
12:31 PM roycroft: and as far as measurement, you measure the hole, not the reamer
12:32 PM roycroft: if it's something critical, you dial it in on some test holes, and hope the setting does not change when you ream the actual feature
12:33 PM roycroft: i don't have any ring gauges, so i'm not sure if that's as accurate as test holes
12:51 PM * roycroft has some adjustable reamers, but usually just buys the correct size reamer when he needs one that he does not have
12:53 PM Tom_L: not really sure i'd consider that a "machinist" tool
01:11 PM roycroft: having a set of adjustable reamers can be helpful in a pinch
01:12 PM roycroft: but a boring head or fixed size reamer is always going to be better, if one has the right size
01:12 PM roycroft: a cnc mill renders all of that moot
03:01 PM CaptHindsight[m]: 5.5" tool steel rounds, do you think the metal suppliers can saw me pieces 0.5" thick?
03:05 PM roycroft: yes
03:05 PM roycroft: will the cuts be square?
03:05 PM roycroft: maybe
03:06 PM CaptHindsight[m]: they spec +- 1/8"
03:06 PM roycroft: then if you need 0.500", order thm 3/4" thick
03:06 PM CaptHindsight[m]: will be turned and milled anyway
03:07 PM CaptHindsight[m]: only need 3/8
03:07 PM roycroft: then get 5/8"
03:07 PM roycroft: since you may have to square up both sides
03:07 PM CaptHindsight[m]: never tried to order something this thin from larger rounds
03:07 PM roycroft: so lunch today was supposed to be making the bends on my part that i've been waiting months to finish
03:08 PM roycroft: i sold my 3-in-1 machine that i used to use for doing metal bending, and only have a little benchtop brake now
03:08 PM CaptHindsight[m]: plasma cut plate
03:08 PM roycroft: i thought i had grooved the part deep enough (it's 0.120 steel) to do the bends, but apparently not
03:09 PM roycroft: so lunch was spent setting the part back up on the mill and making the vee grooves deeper
03:09 PM roycroft: but i was able to do one of the bends after that
03:09 PM roycroft: and since i was already stretching my lunch break to get that much done, i stopped there
03:09 PM roycroft: i shall finish after work
03:09 PM roycroft: i need a better brake setup than what i have
03:10 PM roycroft: but of course it needs to be compact and portable
03:10 PM roycroft: i'm using something like this:
03:12 PM roycroft: https://www.harborfreight.com/18-inch-bending-brake-39103.html
03:13 PM roycroft: i think a beefed up version of that would be fine
03:13 PM roycroft: it should be simple to make
03:14 PM CaptHindsight[m]: https://www.harborfreight.com/30-inch-shear-press-brake-and-slip-roll-5907.html
03:17 PM roycroft: yeah, that's what i used to have
03:17 PM roycroft: i sold it earlier this year to make some space in the fabrication shop
03:17 PM roycroft: 90% of my use of it was the brake
03:28 PM roycroft: it looks like the 30" version of that brake is thicker than the 18", so maybe i should get that and do some mods to it
03:30 PM CaptHindsight[m]: the one I got has held up, lucky it had no large casting voids
03:31 PM CaptHindsight[m]: i think i got mine with a hefty discount
03:32 PM CaptHindsight[m]: never do anything very heavy on it, but it holds up for lots of thin sheet
03:32 PM CaptHindsight[m]: attempts at strips of 12ga SS sort of worked, tested the casting strength
03:41 PM roycroft: i don't do much sheet metal work
03:42 PM roycroft: but it's handy to have a few tools that can make that kind of stuff easier
03:44 PM CaptHindsight[m]: if you have a press you can add a brake to it
03:45 PM CaptHindsight[m]: https://www.youtube.com/watch?v=4Ey5DHMYLZg
03:50 PM roycroft: that's not a bad idea
03:50 PM roycroft: that particular one may be a bit overbuilt
03:51 PM CaptHindsight[m]: ask JT about the one he made
03:55 PM CaptHindsight[m]: https://www.jegs.com/i/JEGS/555/81492/10002/-1
04:00 PM roycroft: that one from jegs.com would be great
04:00 PM unterhaus: oddly specific: microsoft says rain to stop in 7 minutes
04:00 PM roycroft: and i would not have to spend any time fabricating it, which is good, because i have too many projects already
04:00 PM roycroft: microforecasts are pretty accurate these days, unterhaus
04:01 PM unterhaus: I don't think they know where I live
04:03 PM roycroft: i think they do
04:04 PM unterhaus: looks like to me that if it stops there is going to be another band of heavy rain in 30 minutes
04:04 PM roycroft: i think they probably shouldn't, but they do anyway
04:05 PM unterhaus: I think they have me located to struble station, which is somewhere near here
04:08 PM unterhaus: google maps acts dumb when you ask for a lat/long if it's not exactly in the right format
04:08 PM unterhaus: probably sends an email to a software dev and they have a good laugh
04:31 PM CaptHindsight[m]: is there an open source dynamic balancer application? last time I looked they were all done as apps
04:32 PM CaptHindsight[m]: https://github.com/hstarmans/rotorbalancer
04:33 PM CaptHindsight[m]: https://www.physicsforums.com/threads/code-software-for-dynamic-balancing-free-open-source.993629/
04:42 PM JT-Shop: I need to adjust the Hikvision camera but it has tamper proof torx screws
04:43 PM JT-Shop: I wonder if I can just knock the pins off with a punch?
04:44 PM JT-Shop: and naturally the tool that came with the camera is not in the box...
04:47 PM Tom_L: or grind em off if you have a tiny grinder
04:47 PM Tom_L: or drill a hole in your torx wrench
04:50 PM roycroft: cut a slot across the torx driver that's the width of the pin
04:51 PM roycroft: an angle grinder should cut it easily
04:51 PM JT-Shop: I just want to adjust the camera not cut the screws off
04:52 PM roycroft: i'm talking about using the angle grinder to cut the slot in the torx driver
04:52 PM roycroft: not in the fastener
04:55 PM JT-Shop: hmm, I'll see if I have a disposable torx driver to cut up
04:55 PM unterhaus: I think the majority of the 1/4" hex drive torx bits I own are security
04:56 PM -!- #linuxcnc mode set to +v by ChanServ
04:59 PM Tom_L: JT-Shop, far as i'm concerned all torx are disposable :)
05:00 PM Tom_L: seems like every couple years they come out with new fastener heads to keep us buying tools
05:00 PM unterhaus: the folding torx tool that the anonymous glass repairman that the insurance company sent are security
05:01 PM unterhaus: I have a slight pang of guilt every time I see that tool, but I never had any idea how to contact the guy
05:01 PM unterhaus: leave the car unlocked, go to work, et voila! glass is fixed when you get home
05:02 PM Tom_L: and all your belongings inside are missing :)
05:02 PM XXCoder: little trick: have nothing inside
05:07 PM PasstScho: hi!
05:08 PM roycroft: i still use a lot of slotted screws on my wood projects
05:08 PM roycroft: slotted brass screws, especially round head ones, look really nice
05:09 PM PasstScho: I am having trouble with my 7i80 configuration
05:09 PM XXCoder: hey
05:10 PM PasstScho: finally found a nopaste...: https://nopaste.linux-dev.org/?1335678
05:12 PM PasstScho: when i try to start linuxcnc again it seems to be registering sserial devices a bit further, recognizing some boards
05:13 PM JT-Shop: wow my buddy needs a db25 external floppy...
05:13 PM PasstScho: 3rd try and linuxcnc shows up, but this time with "hm2/hm2_7i80.0:error after doit clear".... any ideas?
05:31 PM unterhaus: what is the 7i80 hooked up to?
05:34 PM PasstScho: it is connected to a second ethernet port and to 7i88, 7i89 & 7i74 and three sserial cards
05:37 PM unterhaus: all of those cards are powered by the same power supply?
05:37 PM unterhaus: are they hooked up to stepper amplifiers?
05:38 PM PasstScho: they are connected to powerful 5V & 24V supplies and jumpers set to ext. supply
05:39 PM PasstScho: I only have it hooked up on my desk. no amps connected so far... only one encoder for testing. sometimes i get the encoder to output counts but after restarting linuxcnc I just get error reports again and no counts even if it starts...
05:40 PM unterhaus: I'm guessing wiring problems and possibly ground problems
05:41 PM unterhaus: if you were getting counts, I assume it worked at one time?
05:43 PM unterhaus: the line "Shutting down and cleaning up LinuxCNC..." bothers me
05:44 PM PasstScho: i'm using short flat-cables (<20cm) and 5V is connected with 0,5mm² cables with <0,5m... could this really be a problem?
05:44 PM unterhaus: so all the ethernet boards share a ground?
05:44 PM unterhaus: how about the encoder?
05:45 PM PasstScho: it worked twice... once a few days ago when i tried and once today. each time after a few startup-tries. starting again and it is not working any more.
05:45 PM unterhaus: that is what makes it sound like a wiring/ground problem to me
05:46 PM PasstScho: ethernet board is only the 7i80...? I guess you mean the 7i89 quadrature board? all those boards are connected to extern 5V supply with extern cables connected to each
05:47 PM unterhaus: sorry, I meant the 7i80 and all the other mesa cards you have attached
05:47 PM unterhaus: the one nopaste you posted shows a failure to talk fully to a 7i70
05:48 PM unterhaus: is that the board the encoder is hooked to?
05:50 PM PasstScho: 7i70 is a sserial io device with nothing connected. encoder is connected to 7i89 via 25pin to 7i80
05:51 PM unterhaus: I would start by disconnecting everything and see if you get different error messages
05:52 PM unterhaus: or at least disconnect the 7i70
05:57 PM PasstScho: hm, maybe that fixed the errors on linuxcnc startup but I don't get counts (and still the "... after doit..." error)
05:57 PM PasstScho:
06:00 PM PasstScho: what would be a clean way to restart this system without rebooting? repowering 7i80 and then starting linuxcnc again?
06:07 PM Tom_L: probably
06:08 PM Tom_L: that's a heap of boards. what you makin?
06:08 PM PasstScho: hm now i see "7i72 channel 1 has old firmware that should be updated"... I ll give it a try
06:08 PM unterhaus: I would start by making a star ground for the 5v
06:08 PM Tom_L: by all means
06:08 PM PasstScho: Tom_L, https://forum.linuxcnc.org/27-driver-boards/41746-mesa-setup-7i98-with-7i88-7i89-7i74-7i70-7i72-7i73
06:08 PM Tom_L: i came late to the show
06:09 PM PasstScho: unterhaus, I know it would be better... but actually this should not cause such problems in a laboratory/desk environment? :-/
06:09 PM Tom_L: never say never
06:10 PM unterhaus: _something_ is causing a communications problem
06:10 PM Tom_L: unterhaus, with sserial or ethernet?
06:10 PM unterhaus: sserial
06:10 PM Tom_L: that might be a pcw question
06:10 PM unterhaus: I don't think it's isolated, is it?
06:10 PM Tom_L: but what cables are you using? cat6?
06:11 PM unterhaus: some of them look homemade
06:11 PM PasstScho: those ethernet cables (for sserial) are cat5e, the flat cables for 25pin are diy
06:12 PM Tom_L: and maybe shorten them to the actual useage length
06:12 PM Tom_L: noting looks too horrible to me though... visually
06:12 PM Tom_L: what amps are those?
06:12 PM unterhaus: the larger power supply is 24 volts?
06:12 PM Tom_L: i doubt they are grounded to the boards
06:14 PM PasstScho: i'll buy 0,5m or 0,3m cables but 2m where the only ones left. rs422 should not have a problem with cat5e 2m? yep power supplies are 5V and 24V (the bigger one). both meanwell
06:16 PM PasstScho: now I am figuring out how to update the sserial devices... maybe it helps
06:17 PM PasstScho: unterhaus, I think sserial is not isolated but RS422/485... should be quite robust
06:18 PM unterhaus: it looks like it must be isolated because the 5v is provided over the serial connection
06:21 PM unterhaus: put all that stuff on a din rail, it's driving me nuts :)
06:22 PM PasstScho: I will - I even made custom din-rail-adapters for it ;-). But I'll put em on din rails when they are ready for the electric cabinet
06:23 PM unterhaus: so you 3d printed the adapters?
06:25 PM PasstScho: nope, using lasercut steel plates with spacer bolts and "bopla TSH35" adapters
06:29 PM PasstScho: uff, sserial card update is too much for me now... need to continue another day
06:31 PM Tom_L: i've not done a sserial card update
06:38 PM roycroft: i just picked up a knife for my paper cutter from the sharpening service
06:38 PM roycroft: i've been really happy with them so far, and the knife is beautifully sharpened, but they charged me $37.50 for the job
06:39 PM roycroft: i'm used to paying $1/inch, and this knife is a bit under 18" long
06:39 PM roycroft: for the heck of it i decided to check prices for new knives online, and the best price i found is $198
06:39 PM roycroft: so now i'm not so unhappy about the $37.50 sharpening fee
06:40 PM Tom_L: still seems like alot for a single cutter
06:40 PM * roycroft wonders why paper cutter knives cost so much more than jointer or thicknesser knives
06:40 PM roycroft: they're all just cutting wood
06:40 PM XXCoder: is build different or something
06:40 PM FinboySlick: It's all the extra thin-ness they added.
06:40 PM roycroft: no
06:41 PM roycroft: it's just a long piece of steel with a bevel ground on one side
06:41 PM roycroft: just like a jointer or thicknesser knife
06:41 PM roycroft: there are five slots in it for mounting, but it doesn't cost much to machine those features
06:42 PM PasstScho: hm, 7i72 seems to be up-to-date... the error message was wrong :-/. I should really find out where these communication errors come from...
06:42 PM roycroft: the good news is that i've had this cutter for over a decade and this is the first time i've had to have a knife sharpened
06:42 PM roycroft: i have two knives total, and when i found i needed to swap the one on the cutter with the spare, i found the spare was dull and had some chips in it
06:43 PM roycroft: so i got that sharpened
06:43 PM roycroft: i'll probably have the other one done when i swap them, and then i should not have to do it again for 20 years :)
06:44 PM roycroft: anyway, my bracket is done and in primer
06:45 PM roycroft: after a 2-1/2 month delay
06:58 PM PasstScho: thanks & gn8!
07:04 PM XXCoder: JT-Shop: zen garden for chickens ;)
07:39 PM unterhaus: a little more guidance about grounds would be nice for sserial cards
08:50 PM -!- #linuxcnc mode set to +v by ChanServ
08:55 PM Tom_itx: Hi
08:55 PM Tom_L: testing an android app...
08:55 PM XXCoder: hey android tom
08:59 PM burklefoo: should PasstScho return: My guess is that there are lost or corrupted packets on the Ethernet connection.
