12:24 AM roycroft: youtube have launched a new harassment technique
12:39 AM roycroft: for a year or so, every video i watch on my tv starts out in "automatic" resolution, which is 144p
12:39 AM roycroft: i have go to in after the video starts and manually lock it to 720p or 1080p
12:39 AM roycroft: that used to last throughout the video
12:39 AM roycroft: but starting tonight, every commercial resets it to 144p
12:39 AM xxcoder: sounds like a bug
12:39 AM roycroft: try reading subtitles at that resolution
12:39 AM roycroft: i think it's intentional on their part
12:39 AM xxcoder: captions is unaffected unless its embedded into video
12:39 AM roycroft: i'm watching a japanese video where it is embedded
12:39 AM xxcoder: ok
12:39 AM roycroft: and there is no audio narration at all
12:39 AM roycroft: so auto-generated subtitles would not work
12:39 AM xxcoder: hm that sucks. not sure why thats being done
12:39 AM roycroft: you would just see things like "sawing", "music", etc.
12:39 AM roycroft: it's being done because they want me to pay money to watch their videos
12:42 AM xxcoder: I wonder if its still possible to even buy non-smart tv now
12:42 AM roycroft: of course it is
12:42 AM roycroft: just go to a thrift store or an antique store
12:42 AM xxcoder: lol
12:43 AM xxcoder: it took me a bit to find non-smart tv
12:50 AM xxcoder: and it was bunch of years ago. I was still working lol
12:50 AM xxcoder: I can picture it being much harder now
04:45 AM Tom_L: morning
04:50 AM -!- #linuxcnc mode set to +v by ChanServ
05:05 AM Deejay: moin
08:14 AM lcnc-relay: <skunkworks8841@> Friday!
08:20 AM Tom_L: all day
08:41 AM -!- #linuxcnc mode set to +v by ChanServ
08:44 AM -!- #linuxcnc mode set to +v by ChanServ
11:08 AM roycroft: it is friday, indeed
11:08 AM roycroft: and we're having a heat wave, starting today
11:15 AM roycroft: 37 today and tomorrow, and 36 on sunday is the forecast
11:16 AM roycroft: which will break records for the days if realized
11:16 AM roycroft: and i have a road trip today
11:16 AM rdtsc-w: 310 Kelvin? whoa
11:16 AM roycroft: fortunately in my car, where the ac works great
11:27 AM lcnc-relay: <skunkworks8841@> but then you are just making the outside hotter!
11:37 AM roycroft: i'm just returning the heat to whence it came
11:38 AM roycroft: it's part of the circle of life
11:40 AM lcnc-relay: <skunkworks8841@> But think about the losses!!!
11:40 AM lcnc-relay: <skunkworks8841@> 😉
12:22 PM lcnc-relay: <captainhindsight_.@> lucid.nonsense@ Midwest, USA, Chicago
12:26 PM lcnc-relay: <captainhindsight_.@> I started up a 2cycle leaf blower that had not been run for several years.
12:27 PM lcnc-relay: <captainhindsight_.@> They ran it dry before storage
12:27 PM lcnc-relay: <captainhindsight_.@> The polymer priming pump was the only casualty
12:28 PM lcnc-relay: <captainhindsight_.@> $13 for a whole carb + spare parts
12:29 PM lcnc-relay: <captainhindsight_.@> Even a new spark plug
12:32 PM Tom_L: i had one of those crack and the motor never ran quite right until i discovered it
12:33 PM Tom_L: didn't know it was cracked
12:34 PM Tom_L: you must have added the same code to the rest of the keys as the right arrow too
12:34 PM Tom_L: they don't move in the gcode window now
12:35 PM Tom_L: wrong window
12:37 PM lcnc-relay: <captainhindsight_.@> This one ran fine with giant hole in the pump
12:38 PM lcnc-relay: <captainhindsight_.@> It just gets fuel all over your pumping finger
12:42 PM Tom_L: never did that or i would have noticed sooner
12:43 PM Tom_L: stihl pole saw
01:27 PM Unterhausen: someone on the email list concluded that linuxcnc is dead because the mailing list gets so few posts
01:27 PM Unterhausen: I'm glad it doesn't get too many posts myself
01:31 PM Tom_L: maybe it means there aren't many problems
01:51 PM rdtsc-w: or maybe it means that youngsters today are more interested in the number of followers of their TikTok and couldn't care less about fabrication
02:24 PM xxcoder: new winston moy video looks fun
02:37 PM Unterhausen: nobody uses the ways of the ancients anymore, they are all on discord
02:39 PM xxcoder: 3d printed guide for placing rubber feet on board. amazing
02:39 PM JT-Mobile: Keyboard jog in flex is almost ready
02:41 PM xxcoder: it was quite good video
03:55 PM lcnc-relay: <.le_potato@> how can i delete old gcode from stock linuxcnc axis screen?
03:56 PM lcnc-relay: <.le_potato@> oh control+k
04:50 PM roycroft: i've been dealing with a device today that is posessed
04:51 PM roycroft: or perhaps just a foreshadowing of our future
04:51 PM roycroft: i was at a customer site, and they have a pots (analog phone) to sip (voip) converter that we installed there for their fax machine
04:51 PM roycroft: i had to reconfigure their network, and hence, the device
04:52 PM roycroft: to access it i hook up an analog phone and press some buttons and it prompts me with its ip address
04:52 PM roycroft: but it did so in russian today
04:52 PM roycroft: i did a factory reset, and when it came back i got the ip address in english
04:53 PM roycroft: but the default password did not work, and it locked me out
04:53 PM roycroft: i rebooted it again and it came back in russian
04:53 PM xxcoder: hope thats not from backdoor
04:54 PM roycroft: the one that homeland security installed?
04:55 PM roycroft: the device is made in china, btw, not russia
05:27 PM roycroft: it's officially the weekend
05:29 PM roycroft: and it's officially hot
05:33 PM xxcoder: fun isnt it
05:33 PM xxcoder: prediction for next few days keeps on lowering a little bit and flatter
05:41 PM xxcoder: https://www.youtube.com/watch?v=oiB1Sm_f48w interesting. he reworks cheap crap wind generator. (hes bit annoying but ok yt channel)
05:53 PM xxcoder: looks like answer is still no, its not worth it
05:57 PM roycroft: i has new 24v power supply
05:57 PM roycroft: which means i have work to do
05:58 PM xxcoder: awesome, you got some wattage'
05:59 PM roycroft: not much
05:59 PM roycroft: only 1.5a
05:59 PM roycroft: but i only need milliamps
05:59 PM xxcoder: wattage is wattage, reardless how much amp it is ;)
05:59 PM roycroft: well, it's 36w
06:02 PM roycroft: hmm
06:02 PM roycroft: i'm planning on building a cupola to go on top of my new shop roof
06:03 PM roycroft: 'cuz it will look cool and it will help keep the shop cool
06:03 PM roycroft: i wonder if i should consider a mini wind turbine to go on top of it
06:03 PM roycroft: i was going to install a weather vane
06:03 PM roycroft: if i can find a turbine that i can make look like a weather vane that could work out nicely
06:03 PM xxcoder: theres one thats actually good, but also 1700 eu or so
06:04 PM roycroft: i don't think i could do a chicken weather vane with a wind turbine
06:04 PM roycroft: maybe a penguin :)
06:04 PM lcnc-relay: <.le_potato@> guys, how is it called that tool
06:04 PM xxcoder: one he tested in that video, couldnt power your 24v 1.5a
06:04 PM lcnc-relay: <.le_potato@> head is bigger than the mouting thing?
06:04 PM lcnc-relay: <.le_potato@> xxcoder: use a car alternator
06:05 PM xxcoder: if I recall right it would need some modification first
06:05 PM * roycroft is trying to figure out what .le_potato is talking about
06:05 PM lcnc-relay: <.le_potato@> so the tool have 8mm diameter
06:05 PM xxcoder: theres kits to turn alternator into windmill dynino
06:05 PM lcnc-relay: <.le_potato@> *is
06:05 PM lcnc-relay: <.le_potato@> it fits in 8mm er20 collet
06:06 PM lcnc-relay: <.le_potato@> but i want to have 12mm diameter to mill
06:06 PM roycroft: so get a 12mm tool and a 12mm collet
06:06 PM lcnc-relay: <.le_potato@> nonono
06:07 PM roycroft: ok, don't :)
06:07 PM xxcoder: theres couple options. one is strunk hold if you need large clearance
06:07 PM lcnc-relay: <.le_potato@> i need larger clearance!
06:07 PM lcnc-relay: <.le_potato@> right
06:07 PM lcnc-relay: <.le_potato@> what is strunk hold
06:07 PM xxcoder: other one is that toolholder extension that can be held by er20 and has er12
06:08 PM roycroft: are you talking about a boring head?
06:08 PM xxcoder: https://schunk.com/us/en/tool-clamping-technology/toolholders/celsio-heat-shrinking-toolholder/c/PUB_8659 example of one, first one I found, not best or compitable with your machine.
06:08 PM lcnc-relay: <.le_potato@> i want to mill that part what 3 axis not capable
06:08 PM lcnc-relay: <.le_potato@> so i want bigger head than collet
06:10 PM lcnc-relay: <.le_potato@> https://www.syndent.com/wp-content/uploads/2021/09/SD_Cylinder_Head_Porting_Tools.jpg
06:10 PM lcnc-relay: <.le_potato@> like this
06:10 PM xxcoder: yu mean fit tool that would need er20 collet into er12?
06:10 PM -!- #linuxcnc mode set to +v by ChanServ
06:11 PM xxcoder: that should be usable yeah
06:12 PM xxcoder: roy https://eclectic-energy.co.uk/product/d400/ one that actually works. but so expensive
06:12 PM lcnc-relay: <.le_potato@> head diameter bigger than collet diameter
06:13 PM xxcoder: yeah I used many tools like that. its no problem at all
06:13 PM lcnc-relay: <.le_potato@> yes but there is something bigger? how its called?
06:14 PM lcnc-relay: <.le_potato@> as i remember there is something 1 edge tool like that
06:14 PM lcnc-relay: <.le_potato@> slab milling tool?
06:14 PM lcnc-relay: <.le_potato@> or side milling cutter?
06:15 PM xxcoder: sorry I am having hard time understanding what you want to do
06:15 PM lcnc-relay: <.le_potato@> ok so you have a 10mm radius circle
06:15 PM lcnc-relay: <.le_potato@> 10mm radius tube!
06:16 PM lcnc-relay: <.le_potato@> and you want to make the inside 12mm radius
06:16 PM lcnc-relay: <.le_potato@> bad example
06:16 PM lcnc-relay: <.le_potato@> i show a pic
06:19 PM roycroft: i'm thinking a boring head
06:20 PM roycroft: which i already mentioned
06:20 PM lcnc-relay: <.le_potato@> no
06:20 PM lcnc-relay: <.le_potato@> http://6-f.cc/nc/index.php/s/Lx4a2E4PcXDkfxf
06:20 PM lcnc-relay: <.le_potato@> from top
06:20 PM lcnc-relay: <.le_potato@> i want to mill a lager diameter in the tube
06:21 PM xxcoder: ahh I understand
06:21 PM lcnc-relay: <.le_potato@> i dont know even how in hungarian called
06:21 PM roycroft: i will not buy this counterbore, it is scratched
06:22 PM xxcoder: I suppose its more complex than the example, or it'd be simply made in lathe
06:22 PM lcnc-relay: <.le_potato@> yes
06:22 PM xxcoder: but yah I dont know what would best way to do larger diameter inside
06:22 PM lcnc-relay: <.le_potato@> so side milling cutter
06:22 PM lcnc-relay: <.le_potato@> have bigger 'head' than 'collet mounting'
06:23 PM lcnc-relay: <.le_potato@> i show exactly what i want
06:23 PM roycroft: if you have a 10mm bore and you need it to be 12mm you would mount the part in a vise, center the spindle over it, insert a 12mm end mill, then bore it oversize
06:23 PM roycroft: and you can get end mills with reduced shafts
06:23 PM xxcoder: roy potato wants larger diameter bore below the smaller diameter one
06:23 PM lcnc-relay: <.le_potato@> exactly!
06:23 PM roycroft: oh
06:24 PM roycroft: turn the part upside down :)
06:24 PM lcnc-relay: <.le_potato@> haha
06:24 PM xxcoder: magic
06:24 PM roycroft: if you're careful you could actually use a boring head for that
06:25 PM lcnc-relay: <.le_potato@> http://6-f.cc/nc/index.php/s/BasY8qictFQ6H6E
06:25 PM roycroft: use a tool that fits in the bore, insert it, lock the z height so it can't come up too much, and bore from the middle of the part down
06:26 PM roycroft: you could also bore 12mm, and then make a reducer sleeve to press in and possibly silver solder in to take the upper part down to 10mm
06:26 PM lcnc-relay: <.le_potato@> is this a joke?
06:26 PM lcnc-relay: <.le_potato@> lol
06:27 PM roycroft: imo it's an operation better done on a lathe than a milling machine
06:27 PM lcnc-relay: <.le_potato@> check the 2nd pic
06:28 PM xxcoder: silver soldering isnt much of an option for such a comlex part
06:28 PM lcnc-relay: <.le_potato@> please check the 2nd pic 😄
06:29 PM xxcoder: saw it yeah
06:32 PM xxcoder: I suppose can always use ballend tool to start rough out the larger bore, then use boring tool to clean it out
06:32 PM lcnc-relay: <.le_potato@> slap milling cutter is for faces?
06:32 PM lcnc-relay: <.le_potato@> *slab
06:32 PM xxcoder: and also to square the inside larger diameter bore ends
06:33 PM xxcoder: dont know, I didnt setup tooling and program for cnc, I just do setup and run :D
06:33 PM lcnc-relay: <.le_potato@> lol
06:33 PM lcnc-relay: <.le_potato@> now i have to find 100mm long tool
06:51 PM lcnc-relay: <.le_potato@> xxcoder what about t-slot milling cutter?
06:52 PM xxcoder: possible? I'm not sure how smooth it could make bore
06:53 PM lcnc-relay: <.le_potato@> after that i can polish with hand
06:54 PM xxcoder: hmm I remember something about hoaring, but I dont nknow if it would work lol\
06:54 PM xxcoder: I would test it before trying it on your part
06:54 PM xxcoder: see if t-slot would work to make a bore
06:55 PM lcnc-relay: <.le_potato@> i have 3 cylinder head for playing
06:56 PM roycroft: well, squeezing the power supply into the cabinet was surprisingly easy
06:56 PM xxcoder: hammer helped I bet
06:56 PM roycroft: i just had to move one of the 48v psus a wee bit
06:56 PM roycroft: no rewiring
06:56 PM xxcoder: not bad
06:56 PM roycroft: i cannot access the logs on the 48v psu though - the 24v one is blocking them
06:56 PM roycroft: but i should not need to access them often, if ever
06:57 PM roycroft: i'm not going to do the 48v wiring bus in my office, though, so i'll be moving operations out the studio, where my electronics bench is
06:57 PM roycroft: and all my wire and connectors
06:57 PM roycroft: the label makers are in my car, though, i just realized
06:58 PM roycroft: and it's 37 degrees outside
06:58 PM roycroft: but both in spite of that and because of that i must retrieve them
06:58 PM roycroft: it could get hot enough in the car to damage the thermal labels, and i'd be out hundreds of dollars in labels
07:06 PM xxcoder: hopefully you're bringing em in now
07:08 PM roycroft: they are inside, and cooling off
07:09 PM roycroft: and i did decide to replace some of the wires - they are stretched pretty tight
07:09 PM roycroft: but only three pair of wires
07:09 PM roycroft: so it won't take long
07:09 PM roycroft: they are the ones that the new ps blocks
07:10 PM roycroft: which is what pushed me to do it now - if i decided to replace them later it would be a lot more work
07:10 PM xxcoder: good idea. wires under constant tension might have issues
07:11 PM roycroft: yes
07:11 PM roycroft: my new garage has shipped, and should arrive as scheduled
07:12 PM roycroft: which means this weekend i need to finish the last few garage roof design details, generate a materials list and cut list, and take care of just about everything else i need to do for the next month
07:12 PM roycroft: i need to order lumber on monday or tuesday
07:13 PM roycroft: so this will be my last minirouter work opportunity for a while
07:13 PM roycroft: maybe i'll finally get the ladder working
07:32 PM Tom_L: le potato, http://tom-itx.no-ip.biz:443/~webpage/cnc/cutters/Keyseat_cutter1.jpg
07:32 PM Tom_L: key seat cutter or woodruff cutter
07:33 PM Tom_L: https://shop.datron.com/product/t-slot-mill/
07:34 PM lcnc-relay: <.le_potato@> Tom_L ty!!!!
07:34 PM lcnc-relay: <.le_potato@> i just figured it out
07:34 PM lcnc-relay: <.le_potato@> t mill will be good for me i think
07:34 PM Tom_L: there are ball mills like that too
07:34 PM Tom_L: https://www.harveyperformance.com/in-the-loupe/undercutting-end-mills/
07:35 PM lcnc-relay: <.le_potato@> T-Cutter looks more massive
07:35 PM Tom_L: you are limited on size
07:35 PM Tom_L: generally those are used to cut a slot in say a motor shaft for a key
07:36 PM Tom_L: there are better ways to machine your part
07:36 PM lcnc-relay: <.le_potato@> tell me
07:36 PM Tom_L: put the large ID on top and mill it then do the smaller one under it
07:36 PM Tom_L: then you won't need special cutters
07:37 PM lcnc-relay: <.le_potato@> uhoh, i dont understand
07:37 PM lcnc-relay: <.le_potato@> what is ID
07:37 PM lcnc-relay: <.le_potato@> inside diameter?
07:37 PM Tom_L: inside diameter
07:37 PM Tom_L: flip the part 180 degrees
07:37 PM Tom_L: and cut it
07:37 PM Tom_L: or get a lathe
07:37 PM lcnc-relay: <.le_potato@> nah, this is the cylinder head
07:37 PM lcnc-relay: <.le_potato@> i cant flip it :p
07:38 PM Tom_L: valve seats?
07:38 PM lcnc-relay: <.le_potato@> no, intake porting
07:38 PM Tom_L: you might be better off with an undercut ballnose and generate a surface and cut the surface
07:39 PM lcnc-relay: <.le_potato@> i found only with 3mm shaft
07:39 PM Tom_L: keep looking :)
07:41 PM lcnc-relay: <.le_potato@> i need something massive one because i need 100mm long
07:42 PM Tom_L: may be special order
07:45 PM Tom_L: you got enough Z for 100mm tool?
07:47 PM lcnc-relay: <.le_potato@> yes
07:47 PM lcnc-relay: <.le_potato@> i modified my mill to get 300mm Z 🙂
07:48 PM lcnc-relay: <.le_potato@> removed the stock gearbox / norton from the machine
07:48 PM lcnc-relay: <.le_potato@> and the mechanical end switches
07:50 PM lcnc-relay: <.le_potato@> i bought that air feed oil stuff
07:51 PM lcnc-relay: <.le_potato@> it makes smoke cloud lol
07:51 PM lcnc-relay: <.le_potato@> it sprays too well
07:52 PM lcnc-relay: <.le_potato@> i think i will use ac pump on 5v
07:52 PM Tom_L: yeah they do that
07:53 PM lcnc-relay: <.le_potato@> all the oil goes to air
07:53 PM Tom_L: i use a mist coolant on mine
07:53 PM lcnc-relay: <.le_potato@> mist coolant!
07:53 PM lcnc-relay: <.le_potato@> i learning these new words
07:53 PM lcnc-relay: <.le_potato@> so its making mist coolant cloud
07:54 PM Tom_L: https://www.ebay.com/itm/315476558325
07:54 PM lcnc-relay: <.le_potato@> this is what i bought
07:54 PM Tom_L: cheap but it works
07:55 PM Tom_L: i turn mine down as far as i can
07:55 PM lcnc-relay: <.le_potato@> is it makes cloud?
07:55 PM Tom_L: i have fans
07:55 PM lcnc-relay: <.le_potato@> my spindle using air cooling
07:55 PM lcnc-relay: <.le_potato@> and makes more coolant cloud
07:57 PM Tom_L: you saw we're getting keyboard jog working on flex didn't you?
07:57 PM lcnc-relay: <.le_potato@> nono
07:57 PM lcnc-relay: <.le_potato@> give me link
07:57 PM Tom_L: not done yet
07:57 PM Tom_L: we're testing
07:57 PM lcnc-relay: <.le_potato@> i seen the messages here
07:58 PM lcnc-relay: <.le_potato@> or need an external controller
07:58 PM lcnc-relay: <.le_potato@> but i like my remote keyboard
07:59 PM Tom_L: i like my pendant for jogging
08:01 PM Tom_L: https://shop.datron.com/product/stepped-double-flute-end-mill/
08:02 PM Tom_L: face milling
08:02 PM lcnc-relay: <.le_potato@> only for face?
08:02 PM Tom_L: those are
08:07 PM lcnc-relay: <.le_potato@> Tom_L: if i use 3d touch, it will automatic calculate the middle?
08:08 PM Tom_L: the probe routines i did have some that will find a hole center or a shaft center
08:08 PM lcnc-relay: <.le_potato@> can touch inside and outside as well?
08:08 PM Tom_L: not at the same time
08:08 PM Tom_L: one is for ID the other is for OD
08:09 PM lcnc-relay: <.le_potato@> thats perfect
08:09 PM Tom_L: unless you wrote a custom one
08:10 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/touch-probe3-2.png
08:10 PM Tom_L: all those work
08:11 PM lcnc-relay: <.le_potato@> looks really good!
08:11 PM Tom_L: the parameters are set on the settings tab
08:12 PM Tom_L: for example if you have a large hole or a small one you can adjust for that etc
08:12 PM lcnc-relay: <.le_potato@> its like 'timout' values?
08:12 PM lcnc-relay: <.le_potato@> limit?
08:12 PM Tom_L: yes
08:14 PM roycroft: the problem with wiring things neatly and labling the wires is not that it's a lot of work to do initially
08:14 PM roycroft: it's that minor changes are also a lot of work
08:15 PM roycroft: that said, i've finished the rewiring, and after testing to be sure everything still works, i can start wiring the new psu
08:16 PM roycroft: but yeah, that took over an hour
08:16 PM roycroft: more like 90 minutes
08:16 PM roycroft: to move a psu 2cm
08:16 PM Tom_L: i'll keep my spaghetti
08:16 PM Tom_L: it works solid but it ain't pretty
08:17 PM xxcoder: just dont let anyone eat it
08:17 PM Tom_L: i do/did alot of testing so it didn't make sense to keep changing things
08:18 PM Tom_L: i have a chart showing all the wires/colors etc
08:18 PM Tom_L: and it was somewhat of a budget build
08:20 PM Tom_L: i've swapped out mesa boards etc so it needs some flexibility
08:20 PM Tom_L: had the limits etc on sserial for a while but not now
08:20 PM lcnc-relay: <.le_potato@> i use rca cable for switches
08:21 PM roycroft: i know i'm kind of odd, on many levels, but i really enjoy making neat wiring harnesses
08:21 PM Tom_L: i had some surplus aero wiring i used which is really good wire
08:21 PM lcnc-relay: <.le_potato@> send pic
08:21 PM Tom_L: who?
08:21 PM lcnc-relay: <.le_potato@> roycroft
08:21 PM Tom_L: roycroft, i know
08:21 PM lcnc-relay: <.le_potato@> about need wiring harness
08:22 PM roycroft: https://roycroft.us/MiniRouter/Wiring3.jpeg
08:22 PM roycroft: that's rather dated now
08:22 PM Tom_L: mine look more like a skunkworks project :)
08:22 PM roycroft: it's a month old
08:22 PM roycroft: :)
08:22 PM lcnc-relay: <.le_potato@> still a mess 😄
08:23 PM lcnc-relay: <.le_potato@> roycroft do you have 3d printer?
08:23 PM roycroft: yes
08:23 PM lcnc-relay: <.le_potato@> print some cable holder
08:24 PM roycroft: there are cable holders installed already
08:24 PM lcnc-relay: <.le_potato@> dual tape on wood
08:24 PM roycroft: i don't need to print them
08:24 PM roycroft: i have zip tie holders screwed down to the base
08:24 PM lcnc-relay: <.le_potato@> oh i see
08:24 PM roycroft: zip tie/tie-wrap
08:24 PM lcnc-relay: <.le_potato@> why dont you do with the other cables?
08:24 PM roycroft: the project is not complete
08:24 PM roycroft: but most of what's installed there is secured
08:25 PM roycroft: i added another psu today
08:25 PM lcnc-relay: <.le_potato@> i want to put everything in to my server cabinet
08:25 PM roycroft: in that picture, there's a 5v psu in the center, and 48v psus on each side
08:25 PM Tom_L: what was the need for 2 48v?
08:25 PM roycroft: on the right, in front of the 48v psu and behind the stepper drivers, i just installed a 24v psu for the limit switches and e-stop
08:26 PM roycroft: 1 for the spindle, the other for the steppers
08:26 PM roycroft: i wanted to make sure i had enough current for all
08:26 PM roycroft: one may have been fine, but i have several of those in stock, so i figured i'd use two
08:26 PM Tom_L: i could have gotten by with 1 transformer on mine but i had 3 so i used them
08:27 PM Tom_L: there were 3 on the surplus rack so i got them all
08:27 PM roycroft: originally i used the 24v psu that came with the machine for the spindle, but realized early on that it was not going to be enough
08:31 PM roycroft: well, time to see how my feng shui is in the studio
08:31 PM roycroft: will there be wifi for the mini-router controller or will there not?
08:31 PM lcnc-relay: <.le_potato@> lol
08:33 PM Tom_L: 3:20am? ... you're up late
08:33 PM lcnc-relay: <.le_potato@> thats right
08:33 PM lcnc-relay: <.le_potato@> im an owl
08:34 PM roycroft: i am old
08:34 PM roycroft: i go to bed at a resonable time
08:34 PM Tom_L: i'm young at heart :)
08:34 PM Tom_L: we'll leave it at that
08:35 PM lcnc-relay: <.le_potato@> how old r u guys
08:35 PM Tom_L: how old is dirt?
08:36 PM xxcoder: as old as earth, as new as freshly exited worm
08:36 PM xxcoder: *from worm
08:41 PM lcnc-relay: <.le_potato@> im young here with 34?
08:42 PM xxcoder: dunno lol. many of long term members here is certainly older, but I ont know many of people here ages.
08:45 PM roycroft: some dirt is really old, and some dirt is really young
08:46 PM roycroft: dirt has the same demographic mix as the folks assembled on this channel
08:46 PM xxcoder: roy as I said earlier ;)
08:46 PM roycroft: anyway, it all works
08:46 PM roycroft: so now i can start wiring up the new psu
08:51 PM Tom_L: le potato, you're just a pup
08:51 PM roycroft: grr
08:51 PM roycroft: i have to go outside
08:51 PM roycroft: the wire i need is in the shop, not in the studio
08:52 PM roycroft: .le_potato: here's the back of my controller cabinet:
08:52 PM roycroft: https://roycroft.us/MiniRouter/FinishedCabinetBack.jpeg
08:53 PM roycroft: and the front: https://roycroft.us/MiniRouter/FinishedCabinetFront.jpeg
08:53 PM roycroft: i'll be adding an emblem to the front eventually
08:53 PM roycroft: perhaps something that i carve out of brass on the machine it's controlling
08:53 PM Tom_L: what's the headphone jack on the front?
08:54 PM Tom_L: looks like..
08:54 PM lcnc-relay: <.le_potato@> roycroft that looks awesome!
08:54 PM roycroft: for the z-touch probe
08:54 PM Tom_L: roy's a woodworker
08:54 PM roycroft: i figured it would be best to plug it into the front
08:54 PM roycroft: so i can remove it and plug it in quickly and easily
08:55 PM Tom_L: not a permanent mount?
08:55 PM roycroft: no, i only need it at the beginning of a job
08:55 PM roycroft: so i figure i'll plug it in, touch down, unplug it, and put it back in the drawer
08:55 PM roycroft: ok, it's down to 34 degrees
08:56 PM roycroft: which means about 40 in the shop (i don't have the ac on)
08:56 PM roycroft: but i'm gonna brave it and dash out to cut some wires
09:00 PM roycroft: i survived
09:00 PM roycroft: but i'm also out of 18g black and 18ga white wire
09:00 PM roycroft: i have enough to hook up the mains, but i need more black to wire the load to the power distribution block
09:01 PM roycroft: i'm going into town tomorrow, so guess i'll finish this up after that trip
09:01 PM roycroft: unless i can find some scraps that are long enough
09:02 PM Tom_L: strip down an old extension cord :)
09:02 PM Tom_L: those would likely be larger though
09:02 PM Tom_L: 14ga or so
09:03 PM roycroft: i'll just use the right wire
09:04 PM roycroft: it's stuff i normally stock anyway
09:04 PM roycroft: and it's probably going up in price every day, so i should restock asap
09:21 PM Tom_L: did you figure out what you're doing for the 10v to the spindle? i can't remember where you were with that
09:27 PM roycroft: yes
09:27 PM roycroft: the spindle controller uses 5v internally
09:28 PM roycroft: i.e. where the potentiometer connects
09:28 PM Tom_L: right
09:28 PM roycroft: i got a 3 conductor ribbon cable to tie into that
09:28 PM roycroft: and i'm providing 5v to it from the mesa board
09:29 PM Tom_L: that works with the 7i96s analog out?
09:29 PM roycroft: yes
09:29 PM roycroft: i have controlled the spindle from linuxcnc
09:30 PM Tom_L: i remember something about 5v but somewhat forgot what the end result was
09:32 PM roycroft: it worked out great
09:32 PM roycroft: i suspected that might be the case
09:32 PM roycroft: and i have just enough black wire to do the run from the psu to the pdb
09:33 PM roycroft: so i don't need to buy more immediately, but i'll check online prices tonight and local prices tomorrow
09:33 PM roycroft: the mains are wired up, but it is time to make pizza, so i think this is the end for tonight anyway
09:33 PM Tom_L: i think i have a spool of red and black somewhere
09:33 PM roycroft: i have a fair amount of red
09:34 PM roycroft: but i use more black and white than red
09:34 PM Tom_L: got that local before they closed
09:34 PM * roycroft needs to power on the controller to ensure all the magic smoke stays in it before fixing dinner
09:34 PM roycroft: no smoke
09:34 PM Tom_L: figure out how to keep the relays powered on an estop?
09:34 PM roycroft: and the green indicator is lit on the psu
09:35 PM Tom_L: i forget the exact issue
09:35 PM roycroft: that's the point of the 24v psu
09:35 PM Tom_L: green is usually good
09:35 PM roycroft: so yes
09:35 PM roycroft: i solved the problem by spending more money and making more work for myself
09:35 PM Tom_L: one approach
09:35 PM roycroft: but this is really good, because now i can send 24v to the limit switches, which is way better than sending 5v to them
09:36 PM Tom_L: so the one 24v is live all the time?
09:36 PM Tom_L: what keeps the logic live during an estop?
09:37 PM Tom_L: does it feed off the 24v?
09:37 PM roycroft: yes
09:38 PM roycroft: the 5v and the 24v will be live all the time
09:38 PM roycroft: 5v feeds the mesa card and the rpi, of course
09:38 PM Tom_L: right
09:38 PM roycroft: the two 48v will lose power on e-stop
09:38 PM Tom_L: which are the steppers & spindle
09:38 PM roycroft: the issue before is that i got a 48v to 12v voltage adapter
09:38 PM Tom_L: gotcha
09:39 PM roycroft: thinking i could use 12v for the e-stop
09:39 PM roycroft: then i realized the circle i backed myself into
09:39 PM roycroft: all the smoke stayed in
09:39 PM roycroft: so it's time to make pizz
09:39 PM roycroft: a
09:40 PM roycroft: and the heat advisory has just been extended until tuesday
09:41 PM Tom_L: gonna be chilly here next few days i think
09:41 PM roycroft: on my way home from my customer visit today i got stuck for a half hour behind a fire crew who were putting out a fire right next to the road
09:41 PM Tom_L: monday 59-66F
09:42 PM roycroft: backtracking would have taken longer than a half hour, so waiting ended up being the right choice
09:42 PM * roycroft heads out to the kitchen
09:58 PM Rhine_Labs: Ahhhh...
09:59 PM xxcoder: had yought for dinner today. didnt wanna cook and heat home
09:59 PM xxcoder: tomorrow is one of my favorite cold meal: maraconi salad burrito
10:10 PM olfluffywf is now known as fluffywolf
10:17 PM roycroft: when i lived at the old house i sometimes had second thoughts about baking a pizza in a heat wave
10:17 PM roycroft: but since i have a heat pump here, and the house is at a comfy temperature, i have no worries about it
10:18 PM xxcoder: my home heats up so easily
