08:11 AM rdtsc-w: meister, I seriously doubt that :)
08:27 AM lcnc-relay: <meisterdippel@> https://youtu.be/oFhAovrLCGA?t=204
08:31 AM bjorkintosh: wow. that is really nice.
08:50 AM Tom_L: meisterdipple... stupid? i highly doubt that. maybe a learning curve higher than you'd like
09:28 AM lcnc-relay: <meisterdippel@> i am more stupid than you think 🙂 but what i am good at is trying things out until it works 😎
09:29 AM lcnc-relay: <meisterdippel@> but anyway, such a datron clone would be a real enrichment for linuxcnc
09:30 AM lcnc-relay: <meisterdippel@> and if there's one thing I can't do at all, it's build beautiful gui's
09:32 AM Tom_L: and flex is the tool for htat
09:34 AM lcnc-relay: <meisterdippel@> i know !
09:35 AM lcnc-relay: <meisterdippel@> but I think one or the other widget is still missing
09:35 AM Tom_L: and it just keeps gettin better
09:40 AM bjorkintosh: <meisterdippel@> i am more stupid than you think 🙂 but what i am good at is trying things out until it works 😎 <-- that's me x 10!
09:48 AM lcnc-relay: <meisterdippel@> I am also a bit overwhelmed with the qt-designer 😦
09:50 AM lcnc-relay: <meisterdippel@> no idea how to create such tiles, with background image
09:51 AM bjorkintosh: it takes a little bit of getting used to.
09:51 AM bjorkintosh: it's a mixture of c++ and python.
09:51 AM bjorkintosh: I don't know c++.
09:54 AM lcnc-relay: <meisterdippel@> i think i can do it better in python code than in the designer, but flex needs the xml layout
09:56 AM -!- #linuxcnc mode set to +v by ChanServ
11:22 AM roycroft: wire and cable has gotten ridiculously expensive
11:54 AM lcnc-relay: <roguish> roycroft: it's the copper
11:54 AM lcnc-relay: <roguish> standard romex has like tripled in price
11:55 AM roycroft: yeah
11:55 AM roycroft: we reached peak copper years ago
11:55 AM roycroft: the price is finally catching up
11:56 AM roycroft: i was just going to order a 100' spool of shielded cable for this mini-router project, in 16ga
11:56 AM roycroft: then i started looking at prices
11:56 AM roycroft: now i'm going to go measure for how much i actually need
11:56 AM roycroft: and 18ga is close to the limit, but it will work
11:57 AM roycroft: i'm used to oversizing wires by one gauge on projects like this
11:57 AM Tom_L: better buy now for any future builds
11:57 AM roycroft: and especially since there will be multiple cables in direct contact with each other that would be wise
11:58 AM Tom_L: prices generally don't go down
11:58 AM roycroft: but with the current cost, i'm going to get what i need
11:58 AM roycroft: this is true
11:58 AM roycroft: but it also requires determining what my future needs might be now
11:58 AM lcnc-relay: <roguish> hey, is there still a linuxcnc live CD image to download ???
11:58 AM Tom_L: i haven't seen one in a while
11:59 AM Tom_L: i got rpi5 wifi worked out using the website image file
12:00 PM Tom_L: the image build doesn't support wifi unil you add it
12:00 PM lcnc-relay: <roguish> i've finally started cleaning up my old BP control system, computer and all, and it's erroring pretty badly. thinking of just reinstalling everything. debian and linuxcnc
12:02 PM roycroft: you don't need a livecd for that
12:02 PM Tom_L: you may need backups though
12:03 PM roycroft: there are installable images for uspace and rtai
12:03 PM lcnc-relay: <roguish> yeah, i know that. been doing linuxcnc for near 20 years
12:03 PM Tom_L: rtai are a bit harder to find
12:03 PM roycroft: sure, but an older version would work for backups
12:03 PM Tom_L: that's it???
12:03 PM roycroft: i'm sure i have some livecd images here, if you need one for that and can't find one
12:04 PM lcnc-relay: <roguish> well, time for a ride...... be back later.................. a couple hours....
12:04 PM Tom_L: capn has the latest rtai on his site
12:04 PM lcnc-relay: <roguish> not nessessary, but thanks Roy
12:04 PM lcnc-relay: <roguish> ciao
12:07 PM roycroft: there is a lot of cable on ebay from china
12:07 PM roycroft: but i'm not willing to pay the 50% tariff
12:08 PM roycroft: it's way more expensive than us-sourced cable with that added
12:08 PM roycroft: plus i get to wait a month or more for it
12:09 PM roycroft: the us-based stuff will probably go way up soon as domestic stock is depleted and the suppliers have to import more from china
12:35 PM bjorkintosh: do any of you know? are portable drill chucks interchangeable?
12:35 PM bjorkintosh: trying to replace a ryobi chuck with a better one.
12:37 PM roycroft: they usually have standard mounts, but there are a variety of standard mounts
12:37 PM roycroft: remove the chuck on the ryobi and measure the diameter and thread pitch of the mount
12:38 PM Tom_L: there are different 'standard' mounts
12:38 PM roycroft: you will find a number of replacements with the same specifications
12:38 PM bjorkintosh: I can't. the stupid thing is stuck so fucking hard I probably need to replace the gear box.
12:38 PM bjorkintosh: at that point, I might as well buy a new one... but I hate to throw this crap away.
12:38 PM Tom_L: crap... hehe
12:38 PM roycroft: and note that some portable drill chucks have a right hand thread and a locking screw, and some have left hand thread
12:39 PM Tom_L: yours may be welded in
12:39 PM bjorkintosh: Tom_L: oh. that might explain that.
12:39 PM bjorkintosh: I've used a pipe wrench on it and it won't come off.
12:39 PM roycroft: or it may be left hand thread and his attempts to remove it may actually be tightening it further
12:40 PM Tom_L: something will give eventually
12:40 PM bjorkintosh: the screw is a left hand thread. it's no longer in there.
12:40 PM roycroft: try an impact driver
12:40 PM roycroft: chuck a piece of hex rod (a screwgun tip will do) in the drill and attach a hex socket that fits on the other end and use an impact wrench to remove it
12:41 PM bjorkintosh: I just realized... I _did_ buy a replacement already. I'm trying to upcycle this one just so that it doesn't end up in the trash.
12:41 PM bjorkintosh: the motor's still good.
12:41 PM bjorkintosh: the gear box is still good.
12:41 PM Tom_L: i just googled how to remove it
12:41 PM bjorkintosh: but as Tom_L noted, it might be welded in somehow.
12:41 PM xxcoder: many of those crap tiny cnc routers use drill motors as "spindle" lol
12:41 PM bjorkintosh: somehow... or due to misuse.
12:41 PM Tom_L: Next, insert a hex key (Allen wrench) into the chuck and tighten the jaws against it. Finally, use a hammer to strike the hex key sharply in a counterclockwise direction (relative to the chuck) to loosen and remove the chuck
12:42 PM bjorkintosh: yes. the jaws are immobile.
12:42 PM roycroft: if it were welded in there would be no point to having that locking screw
12:42 PM Tom_L: after removing the already removed lh screw
12:42 PM roycroft: tom_l: that is pretty much exactly what i just said
12:42 PM roycroft: you described a "manual impact wrench"
12:42 PM Tom_L: you're nearly as smart as AI :)
12:42 PM roycroft: my method is better
12:42 PM Tom_L: no doubt
12:44 PM bjorkintosh: I should have splurged and bought a Hilti.
12:44 PM bjorkintosh: I wouldn't be having any of these issues.
12:45 PM roycroft: even high quality tools can succumb to abuse/heavy use
12:46 PM roycroft: it usually takes more to abuse them to the point of failure, but it can be done
12:46 PM Unterhaus_ is now known as Unterhausen
12:51 PM rdtsc-w: Chuck it onto a big hex wrench in a vice, and give the trigger a pull ;)
12:51 PM rdtsc-w: *vise
12:52 PM roycroft: that may work, but the impact action is important if it's really stuck
12:52 PM roycroft: your method may twist his arm off
12:52 PM bjorkintosh: I can't understand why it got so badly stuck though.
12:52 PM rdtsc-w: air hammer - brrrrrrrrrrt
12:52 PM roycroft: which would be counterproductive
12:52 PM bjorkintosh: I would need my arm, indeed.
12:53 PM rdtsc-w: btw, seafoam penetrant out-beat competitors in a recent shoot-out
12:53 PM rdtsc-w: for removing stuck metal parts
12:53 PM rdtsc-w: even over acetone + ATF
12:54 PM -!- #linuxcnc mode set to +v by ChanServ
12:55 PM bjorkintosh: okay.
12:55 PM -!- #linuxcnc mode set to +v by ChanServ
12:55 PM bjorkintosh: I've got blaster PB, but I'll get seafoam.
12:55 PM Tom_rpi5: well i acomplished one thing today anyway
12:56 PM * rdtsc-w waves to top_rpi5
12:56 PM rdtsc-w: *tom_rpi5 d'oh
12:56 PM Tom_rpi5: did you see my comments in flex?
12:56 PM bjorkintosh: rdtsc-w: you don't use tab completion for names?
12:56 PM Tom_L: you don't need the wpa_xxxx or interfaces files
12:56 PM rdtsc-w: oh, heheh, guess that does work here lol
12:57 PM rdtsc-w: ok Tom, yeah each release seems quite a bit different though
12:57 PM Tom_L: they are
12:58 PM Tom_L: once you get rid of those (they do interfere) it's easy
01:01 PM Tom_L: the download page is wrong about using menu-config for wifi
01:01 PM Tom_L: somewhat wrong
01:01 PM Tom_L: you have to have created them before they will show up there
01:22 PM rdtsc-w: "rpi5 growing pains"
01:31 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/rpi5/rpi5_wifi_steps.txt
01:50 PM roycroft: if i am installing an hdmi port in a panel, should the wider or narrow long end go up?
01:50 PM roycroft: i've looked at several devices that i own and most of them have the wide end up
01:50 PM roycroft: but not all
01:50 PM bjorkintosh: sideways?
01:51 PM roycroft: if the wide end is horizontal
01:59 PM bjorkintosh: on my monitor, it's narrow end down.
01:59 PM bjorkintosh: on the corresponding computer, it's narrow end up.
02:00 PM * roycroft would think there would be a standard orientation
02:00 PM roycroft: i'll have to decide what to do
02:00 PM roycroft: both my usb and hdmi panel mount connectors mount with two screws, in opposite corners
02:01 PM roycroft: the usb connector has them in hte upper left and lower right corners
02:01 PM roycroft: if i mount the hdmi connector narrow end down, like almost everything i have that i've checked, the screws go in the upper right and lower left corners
02:01 PM roycroft: so the opposite hole pattern
02:02 PM roycroft: whether i think that's weird or not i've not yet decided
02:02 PM roycroft: it's a mirror symmetry, vs. a linear symmetry
03:38 PM Tom_L: roycroft, long edge up
03:38 PM Tom_L: better yet, mount them sideways
03:42 PM bjorkintosh: <bjorkintosh> sideways? <-- echo!
03:43 PM rdtsc-w: diagonal, for the diabolical
03:44 PM bjorkintosh: screws are already diagonal.
03:45 PM xxcoder: use the free-rotating connector so it could be any angle
03:54 PM lcnc-relay: <meisterdippel@> https://cserver1.multixmedia.org/lcnc-next.png
03:54 PM lcnc-relay: <meisterdippel@> I am still testing / playing with the layout
03:55 PM Tom_L: nice gradient
03:56 PM rdtsc-w: that smells like 2025... nice work :)
03:57 PM xxcoder: windows menu gui
03:57 PM xxcoder: it looks very clean touch gui though
04:00 PM lcnc-relay: <meisterdippel@> thanks, but now i have to go to bed, gn8
04:08 PM Tom_L: cool, it just works.
04:08 PM Tom_L: wifi and eth0 to mesa
04:10 PM -!- #linuxcnc mode set to +v by ChanServ
04:10 PM -!- #linuxcnc mode set to +v by ChanServ
04:10 PM Tom_L: the menus are a little borked on the image though
04:10 PM Tom_L: lcnc shows up in acessories, cnc, and science
04:10 PM Tom_L: haven't seen a science one yet
04:14 PM lcnc-relay: <ccatlett1984@> Need to pull an Apple, and implement Windows Vista "Aero" theme....
04:14 PM lcnc-relay: <ccatlett1984@> Lol
05:29 PM roycroft: i'd like to implement a st:tng theme on my linuxcnc machines
05:29 PM roycroft: i wonder if flex can do that
05:30 PM lcnc-relay: <ccatlett1984@> LCARS 😉
05:31 PM roycroft: i was privileged today to get behind an rv that ran a stop sign and turned right in front of me
05:31 PM JT-Shop: what is a st:tng them
05:31 PM roycroft: it then proceeded to travel at 30mph all the way up until i got home
05:31 PM roycroft: and i got to follow it the whole way, because every time there was a passing zone it straddled the road
05:32 PM roycroft: so my 20 minute drive took an hour
05:32 PM roycroft: the graphics on their computer displays, jt-shop
05:32 PM roycroft: let me find an example
05:32 PM bjorkintosh: star trek: the next generation.
05:33 PM roycroft: https://wall.alphacoders.com/big.php?i=511379
05:33 PM roycroft: there's one, not a great example, but the first one i found
05:34 PM roycroft: i'd only want to use it on a large display, because it's kind of wasteful of real estate
05:34 PM roycroft: but it would look pretty cool
05:35 PM xxcoder: lcars fun
05:35 PM xxcoder: you probably can cheat by just having lit scencils around actual screen
05:35 PM xxcoder: few tiny montiors for details that change
05:35 PM roycroft: https://en.wikipedia.org/wiki/LCARS
05:36 PM roycroft: a more formal discussion of it, with a better example
05:36 PM bjorkintosh: oh the colors are great.
05:36 PM JT-Shop: that can be done with a qss stylesheet file
05:37 PM roycroft: yes, most of the work would be the stylesheet
05:37 PM roycroft: and while i don't know a whole lot about flex at this point, my impression is that it lives up to its name - it is very flexible
05:38 PM JT-Shop: the flex qss builder can help with creating stylesheet files
05:38 PM JT-Shop: thank you
05:39 PM roycroft: i need a working machine before i concern myself with a user interface
05:39 PM roycroft: so it's not that i'm ignoring the flex project
05:39 PM JT-Shop: yup
05:39 PM roycroft: it's just that it's not time for it yet for me
05:39 PM JT-Shop: axis is the best to start with... it just works
05:40 PM roycroft: yes, that's what i'm using as i build the machine
05:40 PM roycroft: and my power inlet and circuit breaker arrived while i was in town
05:40 PM roycroft: so now i can finish the back panel design and cut it out
05:43 PM JT-Shop: once your machine is running then flex can be used to tailor it to your work practices
05:43 PM roycroft: yes, that is exactly what i anticipate
05:43 PM roycroft: i'll get it functional with axis
05:43 PM roycroft: figure out the work flows that i need
05:44 PM JT-Shop: yup
05:44 PM roycroft: and then use flex to develop a new user interface that is optimized for my work flows
05:44 PM roycroft: but until i get using the machine and figuring out my work flows there's nothing to optimize
05:46 PM Tom_L: i forgot what i used to make a pi bakup image it's been so long
05:48 PM roycroft: i use dd
05:49 PM Tom_L: ahh.. win32diskimager
05:50 PM Tom_L: i think
05:55 PM Tom_L: roycroft, will dd copy the whole sd or just the used part?
05:58 PM bjorkintosh: the whole device.
05:59 PM bjorkintosh: it's flexible enough to choose otherwise, of course.
05:59 PM Tom_L: well the win imager does the whole thing too
05:59 PM bjorkintosh: https://blog.kubesimplify.com/the-complete-guide-to-the-dd-command-in-linux
05:59 PM Tom_L: i'm not savvy enough with dd to be selective
06:04 PM roycroft: dd will do what you tell it to do :)
06:04 PM roycroft: for what you're taking about i generally dd the raw disk image
06:04 PM roycroft: including the boot block, partition table, etc.
06:04 PM Tom_L: right
06:05 PM roycroft: so that i can dd it back onto a blank sd card
06:05 PM roycroft: but you can dd just a partition if you want
06:05 PM roycroft: dd if=/dev/rdisk0 ...
06:05 PM Tom_L: it just takes longer to backup the whole thing than just the used part
06:05 PM roycroft: dd if=/dev/disk0p1 ...
06:05 PM Tom_L: and has to restore to that size or larger media
06:05 PM roycroft: yes and yes
06:06 PM xxcoder: some people do size partition as small as possible, so you would need to extend it after dd
06:06 PM Tom_L: i generally wind up using the win utility since it's the pc that doesn't get messed with while testing
06:07 PM bjorkintosh: Tom_L: are you looking for rsync instead?
06:08 PM lcnc-relay: <sodakaustik@> We speaking theory here - PID speed control, would a Derivative term ever make sense?
06:09 PM bjorkintosh: rsync works over ssh too. quite convenient.
06:15 PM Tom_L: i've got it now
06:16 PM Tom_L: i don't think i've used rsync but this is just for an rpi sd backup
06:20 PM * Tom_L wonders how many more different ways debian can think up to set up networking
06:21 PM JT-Shop: lol
06:21 PM Tom_L: it's very easy once you figure it out
06:35 PM * JT-Shop calls it a night
06:39 PM rdtsc: sodakaustik: https://pidexplained.com/how-to-tune-a-pid-controller/ perhaps... D term is usually very small, if any
06:48 PM roycroft: you can tune a pid, but you can't tune a fish
07:11 PM * roycroft is ready to make a sample back panel
07:11 PM Tom_L: how many pannels does it take to get one good one?
07:12 PM xxcoder: as many as needed
07:12 PM roycroft: it should take a sample then the final one
07:12 PM roycroft: the first one i did in three goes
07:13 PM roycroft: i made a sample of one side using 3/16" plywood
07:13 PM roycroft: then i did a full thickness sample with cutouts in the front and back
07:13 PM roycroft: then the actual part
07:13 PM roycroft: this time i'm skipping the plywood and going straight for the full thickness sample
07:15 PM roycroft: i consider myself still learning the tool
07:15 PM roycroft: eventually i'll stop making samples of most things and go straight to confidently cutting the final part
07:15 PM roycroft: but i'm not there yet
07:16 PM roycroft: i have two air exhaust vents to machine in the back panel, so this is going to take a while
07:17 PM roycroft: but first i have to find my thumb drive or i'm not going to make anything
07:21 PM roycroft: i think i can cut the back panel features into the front panel sample and still determine if it's going to work or not
07:21 PM roycroft: there will be a lot of extra holes/features, but i think i can work around all that
07:33 PM lcnc-relay: <big_kevin420@> how many till the good one? ill let you know, im working on number...3-4 right now
07:33 PM lcnc-relay: <big_kevin420@> high density connector edition
07:34 PM lcnc-relay: <big_kevin420@> gonna simplify io wiring on this one
07:38 PM lcnc-relay: <big_kevin420@> https://media.discordapp.net/attachments/970073761770512384/1384328656733737061/connector16b.jpg?ex=68520807&is=6850b687&hm=5952085abd178a30997a894fa4f65d52ce87a26cd341ee8933605c36a26fde3a&=&format=webp&width=1136&height=790
07:39 PM Tom_L: looks like the round ones had some teeth pulled
07:40 PM lcnc-relay: <big_kevin420@> im running out of crimp terminals and wire, i need to cut up the encoder wires that are on thje machine right now to make several smaller wires
07:40 PM lcnc-relay: <big_kevin420@> these round amp connectors apopear to take the same crimps as DB25, so thats lucky
07:43 PM lcnc-relay: <big_kevin420@> i wanna use one of these murr block things (not the cube67io, but directIO)
07:43 PM lcnc-relay: <big_kevin420@> https://shop.murrelektronik.com/out/pictures/master/product/1/IMG851375_zoom.png
07:43 PM lcnc-relay: <big_kevin420@> but i think its gonna eat up a lot of space
07:43 PM lcnc-relay: <big_kevin420@> but i grow tired of wiring all these 3 wire sensors into the panel
07:44 PM bjorkintosh: make a small kevin do the wiring for candy or something.
07:45 PM lcnc-relay: <big_kevin420@> small kevin who would do the wiring is busy fixing his car and the spectrometer he snagged from work, so hes been too busy to help
07:45 PM lcnc-relay: <big_kevin420@> otherwise i could trick him into doing the wiring, like everyone else at work does
07:46 PM bjorkintosh: hahahah
07:46 PM lcnc-relay: <big_kevin420@> it sends mixed messages if i tell him to not do wiring for other people every day, and then ask him to do my wiring
07:46 PM Tom_L: it's for family....
07:47 PM Tom_L: tightens the bond...
07:47 PM lcnc-relay: <big_kevin420@> lol hes not my son, just the only guy i manage at work.
07:48 PM lcnc-relay: <big_kevin420@> he figured out how to load all this old work software thought. something about using VM and DLL file stuff
07:49 PM lcnc-relay: <big_kevin420@> got this old swiss lathe cam program that we need now, needed to run it in a windows XP vm
07:49 PM lcnc-relay: <big_kevin420@> it looks like it sucks ass, so i want him to learn it insetad of me
07:52 PM bjorkintosh: what is the software called?
07:52 PM lcnc-relay: <big_kevin420@> hmmm
07:52 PM lcnc-relay: <big_kevin420@> something for tsugami
07:53 PM lcnc-relay: <big_kevin420@> abile
07:53 PM bjorkintosh: ah I see.
07:53 PM lcnc-relay: <big_kevin420@> it is....really clumsy to use, but its made for this machine, so had a post for it already
07:54 PM lcnc-relay: <big_kevin420@> i want to so bad, tell my manager to get the mastercam lathe + post for $4000
07:54 PM lcnc-relay: <big_kevin420@> he asks me, and i tell him, not yet, the lathe might not even work
07:55 PM lcnc-relay: <big_kevin420@> you cant import models into it
07:56 PM bjorkintosh: don't get me started on ancient japanese CAM software.
07:56 PM * bjorkintosh mutters in mazak
07:57 PM lcnc-relay: <big_kevin420@> so its probably bad like that then, they didnt make it easy to use, but i feel confident in the behavior of the posted gcode
07:58 PM lcnc-relay: <big_kevin420@> except for the sub spindle....and all the tools around everything
07:58 PM lcnc-relay: <big_kevin420@> and the bar feeder
08:08 PM -!- #linuxcnc mode set to +v by ChanServ
08:41 PM roycroft: well that sample came out just about perfect
08:41 PM roycroft: two minor tweaks that i can do on-tool
08:41 PM roycroft: it took about an hour to cut
08:41 PM roycroft: it took longer than that to get the file ready
08:42 PM * roycroft will probably not go back out to the shop after dinner, and so will cut that panel tomorrow
08:42 PM roycroft: i'm starting to get the hang of the tool, finally
08:43 PM roycroft: and i think i even got my order of operations perfect - i did not have to switch to the same cutter twice at all today
08:46 PM Tom_L: win win
08:46 PM lcnc-relay: <skunkworks8841@> Lol.. we had a mini Mike at work...
08:47 PM lcnc-relay: <skunkworks8841@> (and classic Mike). He is a lot older
08:50 PM Tom_L: pcw--home, i'm trying to remember on the 7i90.. there's no jumper for spi just change the hm2 driver and connection is that right?
08:50 PM Tom_L: i didn't see a jumper for it
08:54 PM Tom_L: i thought i'd revisit it on the rpi5
08:59 PM pcw--home: Tom_L: You need to change the firmware to SPI firmware
09:00 PM Tom_L: even to run mesaflash?
09:01 PM Tom_L: i was just planning to test the connection
09:01 PM Tom_L: not try and run anything
09:01 PM Tom_L: iirc i have to do that via epp...
09:02 PM Tom_L: mmm i wonder if i still have a spi firmware around
09:17 PM Tom_L: well i can't seem to find one.
09:20 PM Tom_L: seveni90spi.xise right?
09:39 PM Tom_L: well i got a bit file...
09:40 PM Tom_L: had to clean the rust off
09:47 PM Tom_L: pcw--home, when i go back to epp, i flash that using the --spi right?
09:53 PM pcw--home: You need --spi and --addr /dev/yourSPIdevice
09:54 PM Tom_L: right
09:57 PM Tom_L: then in the config file i use the new spi driver for the rpi5
09:58 PM Tom_L: i mostly want to check the interface so i doubt i go as far as to the config file anyway
10:25 PM pcw--home: Also need to enable SPI on the RPI
10:27 PM Tom_L: right
10:27 PM Tom_L: i think it is
10:28 PM Tom_L: it has more than 1 spi port
10:28 PM Tom_L: 0, 1 & 10?
10:29 PM pcw--home: I think the 7C80/7C81 with direct cable connections use SPI0
10:30 PM Tom_L: i think so as well
10:30 PM Tom_L: i think rdtsc discovered that
10:31 PM Tom_L: i have a short cable i used from the rpi4
10:33 PM pcw--home: (The 7C80/7C81 could of course use SPI1 with different firmware, the 7I90 doesn't care since it has no standard 1:1 cable )
10:34 PM Tom_L: i'm pretty sure SPI0 will match what the rpi4 pinout was
10:36 PM Tom_L: ok well it will be a tomorrow project
10:36 PM * roycroft is pondering going back out to the shop for a bit
10:37 PM roycroft: i have plenty of in the house projects to work on
10:37 PM roycroft: the mini-router controller project is about to get really interesting, though, and i may need some time for the next phase
10:38 PM roycroft: the panel inserts are going to be brass plate, and i intend to make the cutouts with the shaper origin
10:38 PM roycroft: i've never machined metal with it
10:39 PM xxcoder: probably would be fine
10:39 PM roycroft: folks do it
10:39 PM roycroft: but like anything else, it's going to take some experimentation on my part to get it working well
10:40 PM roycroft: i got a box of end mills out of storage, so i may use those instead of router cutters
10:40 PM Tom_L: it's a harder metal
10:40 PM roycroft: yes
10:40 PM Tom_L: cuts more like steel than aluminum
10:40 PM roycroft: i have my metal treating oven here
10:41 PM roycroft: so i can anneal it pretty easily before i start machining it
10:41 PM Tom_L: and copper is down right nasty
10:41 PM roycroft: i don't know if the brass sheet i have is soft, half hard, or hard
10:41 PM Tom_L: that might just make it gummy
10:41 PM roycroft: i also don't know what alloy it is
10:41 PM roycroft: copper is all buttery
10:42 PM roycroft: i love the look of copper, but i hate working with it
10:42 PM xxcoder: grease em up
10:42 PM roycroft: i actually like the look of many bronzes better, and bronze is almost universally easier to machine than copper
10:42 PM xxcoder: honestly dunno if would work on router too but yeah
10:43 PM roycroft: folks on the shaper forum use router cutters for brass all the time
10:43 PM roycroft: but they have mixed expectations and results
10:47 PM roycroft: i have way more of the brass sheet than i need, so that is good, as if i screw up i still have some more, but the stuff is getting really expensive, making my plan be to not screw it up
10:48 PM roycroft: i have a bunch of cable coming too
10:48 PM xxcoder: can always use wood to ensure its all correct
10:48 PM xxcoder: then scrap bronz to test how well cutter works?
10:48 PM roycroft: nothing personal, xxcoder, but those flat, unshieled cables on the mini-router bug me a lot
10:49 PM roycroft: and they are not long enough
10:49 PM xxcoder: lol yeah. I did plan to rewire with much better wires
10:49 PM xxcoder: it was still in testing stages after akkl
10:49 PM roycroft: i ordered some 4 conductor shielded cable
10:49 PM roycroft: 18ga for the motors
10:50 PM roycroft: and some 2 conducter shielded cable for the spindle motor
10:50 PM xxcoder: I forget what ga I used, but probably was too thick
10:50 PM roycroft: well the drivers are set to 4.5a, and that's what the motors can handle, and 18ga is good for 5a
10:54 PM roycroft: i'll probably replace those screw terminals at the motors with 4 pin molex connectors
10:54 PM roycroft: i have a big box of those somewhere - i'll need to find it
10:57 PM * roycroft heads out to the shop to at least setup and decide whether to spend the hour to cut the part
