12:30 AM lcnc-relay: <meisterdippel@> moin
01:10 AM lcnc-relay: <sodakaustik@> morning!!!
01:11 AM lcnc-relay: <sodakaustik@> get this: micro-servo jog buttons with tactile feedback for load torque
01:12 AM lcnc-relay: <sodakaustik@> imagine crashing your machine and getting punched in your finger promptly
01:13 AM lcnc-relay: <sodakaustik@> same is possible with jog wheels
01:15 AM lcnc-relay: <meisterdippel@> coool 🙂
01:16 AM lcnc-relay: <meisterdippel@> or at least when you hit the soft limit
01:26 AM jpa-: sodakaustik@: if you have load feedback, why not just limit jogging force so that it doesn't crash that hard :D
01:34 AM lcnc-relay: <meisterdippel@> https://www.youtube.com/watch?v=xTlv1rPEqv4
02:44 AM mrec_: did anyone try to power on a middle age CNC without the motor power attached? I wonder what I would expect. I have a problem with a new encoder on my machine
02:44 AM mrec_: that shitty meldas control does high speed rapids to follow the encoder value it seems which is very nice for crashing the machine
02:44 AM mrec_: it seems like the encoder is an absolute encoder
02:44 AM mrec_: to a certain degree at least
02:45 AM mrec_: I'm just afraid of releasing the emergency because I just had a light crash before but now the machine did a full speed rapid on the Z axis upwards
02:45 AM mrec_: the old encoder is dead and of course the documentation is soso.
02:46 AM jpa-: no way to limit maximum motor speed?
02:46 AM mrec_: this rapid thing is an absolute BS
02:47 AM mrec_: I set everything very low .. Z rapid default is 15m
02:47 AM mrec_: 15m/min
02:48 AM mrec_: what a shit...
02:48 AM mrec_: if that thing releases from emergency and does a rapid down it will be dead
02:53 AM rmu: how does control communicate with the servo drives?
02:55 AM mrec_: it sends absolute positions
02:55 AM mrec_: init encoder ... the feature in the settings gives me an error, and no further information about it in the documentation
02:55 AM mrec_: what a headache..
02:56 AM rmu: can you monitor the protocol?
02:57 AM mrec_: the problem is I don't know how to set the encoder hmm.....
02:57 AM rmu: you could open couplings between motor and ballscrew/ballnut or whatever is converting rotary to linear motion
02:58 AM rmu: of course you have to recalibrate machine-zeros etc... after that
03:05 AM mrec_: disengaging the motor would be the very best
03:08 AM mrec_: I will put some steel bars into the vise and try to lock it into place
03:09 AM mrec_: I'm worried about the rapid movements they are not okay
03:11 AM rmu: i don't know your machine but with a retrofit i did on an old analog system IIRC i put a bunch of z-diodes accross the +-10V terminals as a safety "cut off"
03:11 AM rmu: that machine also has scary rapids, 80m/min on x/y
03:14 AM mrec_: I see nothing about rapid movements in the documentation
03:14 AM mrec_: nothing that I didn't change yet
03:15 AM mrec_: X/Y I can easily disengage the motor but Z is problematic
03:20 AM lcnc-relay: <pink_vampire@> my gantry got a belt.. now I just need to do 32 solder connections, and drill soooo many holes for the rails, and my large 1000x2000mm cnc machine is done!
03:49 AM mrec_: the servo shows up Error 31 overspeed how cute
03:50 AM mrec_: I will release the emergeny stop when everyone is gone here and see what disaster will happen
03:56 AM lcnc-relay: <lucid.nonsense@> meisterdippel@: Would be cool to have for manual lathe work especially, but ties in nicely with chatter detection, expensive though
04:23 AM Tom_L: morning
04:31 AM lcnc-relay: <lucid.nonsense@> God morgen
04:38 AM mrec_: mitsubishi engineers who worked on that meldas amplifier are retards.
04:40 AM -!- #linuxcnc mode set to +v by ChanServ
04:51 AM mrec_: as assumed the machine just crashed with a rapid into Z max
05:16 AM JT-Cave: my arms are sore this morning
05:24 AM lcnc-relay: <lucid.nonsense@> Not surprising, sore muscles are a good thing though, sore joints from overdoing things not so much.
06:51 AM -!- #linuxcnc mode set to +v by ChanServ
06:56 AM -!- #linuxcnc mode set to +v by ChanServ
07:01 AM mrec_: I fixed my problem .. while overall I'm very fine with the old meldas system, the encoder integration is messy
07:10 AM rdtsc-w: commercial machines all use really oddball encoders - yet another way for proprietarization
07:12 AM rdtsc-w: a motor shop pays thousands of dollars a month for software which can talk to just *some* of those encoders
07:21 AM mrec_: the system is 1998, what Mitsubishi has done there is potentially dangerous. If the encoder have problems someone might get injured badly
07:21 AM mrec_: back then the Y axis oscillated and crashed and killed the bearings after powering it up. it did not respect the movements from the handwheel but just ran a rapid into the waycovers
07:23 AM mrec_: that was at the beginning, shortly after that the amplifier also died. The Z axis had a similar behaviour just not that strong from the beginning on (but especially after cold starting the machine it needed to be handled slowly at the beginning)
07:24 AM mrec_: but this time I changed the encoder... so what I did was just I disconnected the servo, plugged the old encoder back in, wrote down the encoder position, replugged the new encoder spinned it into the area of the old encoder and connected the amplifier again - that worked
07:25 AM mrec_: initially I only put in the encoder and powered on the machine (still with emergency stop pressed) I lowered all the rapid speed settings and released the emergency stop - the Z axis ran straight into Z max (well I stopped it like 10 cm before the end of it, but when releasing the emergency stop it crashed into it)
07:27 AM mrec_: it should never ever do such big movements, this just screams for a disaster in the field.
07:27 AM mrec_: the control system delivers absolute values to the amplifier - it seems like it doesn't actually use the value that comes from the encoder
07:45 AM rdtsc-w: not ideal, if it's indeed supposed to work that way
07:53 AM lcnc-relay: <lucid.nonsense@> rdtsc-w: Fanuc encoders are deliberately obtuse
08:08 AM lcnc-relay: <skunkworks8841@> Mesa can read some of the proprietary encoders
08:13 AM lcnc-relay: <lucid.nonsense@> Yeah looked into it, but no go for the two fanuc motors I have
08:15 AM lcnc-relay: <lucid.nonsense@> Think Excessive Overkill deciphered one of the encoders I have, but think I'll just take the easy route and use the stack AS5047P I have
08:15 AM lcnc-relay: <lucid.nonsense@> *of
08:26 AM mrec_: reverse engineering those encoders isn't the biggest problem it's understanding how the entire blackbox works together
08:27 AM mrec_: there are also many options available, which certainly also play some role here
08:28 AM rdtsc-w: I wonder if Siemens Drive-Cliq encoders are encrypted, because nothing can read them
08:28 AM mrec_: when powering on the machine - and not touching it it will not move. When using the handwheel eg. 1 micron it first seems to command the amplifier to go to the position where it was before powering down (I think it's this position). and this position is stored on the encoder. The system doesn't sync this back, in a working system it doesn't have to
08:32 AM rdtsc-w: hmm do have a 200MHz logic analyzer... should 'scope across drive-cliq and see what happens - someday
08:38 AM rdtsc-w: yeah encoder "home" positions are weird, and vary by machine
08:43 AM mrec_: in the machine the encoders are actually set to incremental
08:55 AM lcnc-relay: <meisterdippel@> rio can also read some absolute-encoders 🙂
08:56 AM lcnc-relay: <meisterdippel@> yaskawa, t3d, stepperonline, panasonic
09:31 AM lcnc-relay: <alekisan@> Hello everyone!
09:31 AM lcnc-relay: I'm just another soul here heading out to sea in search of EtherCAT island. Have any of you guys found it?
09:31 AM lcnc-relay: I've gotten as far as hooking everything up and getting all devices to show up when you run the 'ethercat slaves' command.
09:31 AM lcnc-relay: I believe the next part is setting up the configs and what not and this is where I am lost. I saw the thread about the EtharCAT Auto-Configurator but was not able to get the code to compile.
09:31 AM lcnc-relay: ... long message truncated: https://jauriarts.org/_heisenbridge/media/jauriarts.org/xYLIRXzOvgMjZKsbpeklhDnd/k4IzGB5qkN8 (8 lines)
11:00 AM JT-Shop: dang the B7500 needs an oil change... it's really black
11:09 AM roycroft: my pickup is in the shop
11:10 AM roycroft: transmission seal leak
11:10 AM roycroft: $600 for labor alone :(
11:10 AM roycroft: and there is no way i'm going to tackle a job like that, especially on my driveway
11:10 AM roycroft: the tranny has to be removed, and in that vehicle it's huge
11:19 AM JT-Cave: front seal?
11:25 AM JT-Cave: Job #3 DONE get all the rounds I rolled off the trailer yesterday off the ground
11:39 AM rdtsc-w: alekisan, a few have attempted EtherCAT but it is few-and-far-between here; gonna require some patience and maybe a post on the forum. There seems to be a resounding lack of details in EC setup however - so when you finally do figure it out, please share for the next soul. :)
11:40 AM roycroft: the seal where the transmission connects to the engine
11:40 AM roycroft: i guess that's the front seal
11:41 AM roycroft: it's a $50 part, but a full day's work
11:42 AM roycroft: for a shop with a lift and the proper equipment
11:42 AM roycroft: it would probably take me a week if i attempted it
11:44 AM rdtsc-w: too bad we don't have teleportation technology yet... bzzzzzt done thanks that'll be $35 plus the $100 teleporter tax.
11:55 AM lcnc-relay: <lesliet@> teleport-in-place repairs
11:56 AM lcnc-relay: <captainhindsight_.@> alekisan@ Sounds to me like a very good question to post on the forums
11:56 AM xxcoder: if teleportion was a thing, even if very limited range, things would have more unionary design. ie it has no bolts and does not seperate case etc. since can always teleport parts out and in
12:00 PM Tom_L: https://forum.linuxcnc.org/24-hal-components/30045-ethercat-config-how-and-why
12:01 PM Tom_L: https://forum.linuxcnc.org/ethercat/47502-configuring-linuxcnc-with-ethercat
12:09 PM lcnc-relay: <skunkworks8841@> roycroft: if they are in there - I would seriously think about replacing the rear engine seal.
12:10 PM Tom_L: at that point they're pratcically staring at it
12:10 PM lcnc-relay: <skunkworks8841@> right.
12:11 PM lcnc-relay: <skunkworks8841@> almost - flywheel? I don't know if it is automatic. It has been a while since I have been in something liket hat.
12:11 PM lcnc-relay: <skunkworks8841@> that
12:11 PM lcnc-relay: <skunkworks8841@> flex plate?
12:11 PM Tom_L: either way it's right there
12:14 PM lcnc-relay: <skunkworks8841@> I watched 'watch wes work' fix his hyster forklift clutch.. (the bolts broke off between the flywheel and the engine) anyway - that thing is similar to the one we have and it had a perkins engine in it. I wonder if one of the perkins around here would drop in.. (the 4 cylinder gas - continental? maybe.. burns so much oil that you can't see what you are doing..)
12:18 PM lcnc-relay: <lesliet@> at least you're mosquito proff while using it
12:18 PM lcnc-relay: <lesliet@> * proof
12:18 PM lcnc-relay: <skunkworks8841@> yah.. yeck.
12:18 PM lcnc-relay: <lesliet@> constitution check + roll saving throw vs cancer
01:05 PM mrec_: did anyone re-grind the spindle taper? I wonder how much that service is charged in various countries.
01:15 PM lcnc-relay: <skunkworks8841@> um... I did it on the matsuura.. you probably don't want to do it they way we did.
01:16 PM mrec_: I will doublecheck the spindle tomorrow, I think I had something like 10 microns runout there but I'm not sure about the contact of the BT45 holders that machine is 25 years old..
01:16 PM lcnc-relay: <skunkworks8841@> https://www.youtube.com/watch?v=2BFTifZgQVs
01:17 PM lcnc-relay: <skunkworks8841@> this was a b35
01:19 PM * JT-Shop goes to napa to get a new start button for the splitter
01:25 PM roycroft: you don't need a stinking start button
01:25 PM roycroft: you have two wires
01:25 PM roycroft: make them one wire
01:27 PM lcnc-relay: <skunkworks8841@> Tom_L: https://photos.app.goo.gl/omA7hGk2okVFvw3UA
01:29 PM lcnc-relay: <skunkworks8841@> roycroft: did you see the comment about the rear main seal?
01:30 PM roycroft: no, i did not
01:30 PM roycroft: i have a small scroll buffer and am afk a lot
01:30 PM lcnc-relay: <skunkworks8841@> if they are in it that far - I would be inclined to have them replace the rear main engine seal
01:30 PM roycroft: hmm
01:30 PM roycroft: i'll talk to them about it
01:31 PM roycroft: that should not add much labor
01:31 PM roycroft: and it's a $50-ish seal
01:31 PM lcnc-relay: <skunkworks8841@> I would not think so..
01:31 PM roycroft: so not more than $150 for the 7.3l engine
01:31 PM roycroft: with the f350 i usually multiply the "normal" cost of parts by 3-5x to get the "ford super duty" price
01:31 PM lcnc-relay: <skunkworks8841@> lol
01:32 PM Rab: Definitely seconding replacing the rear main seal.
01:32 PM lcnc-relay: <skunkworks8841@> yep
01:32 PM roycroft: everything is bigger and badder on that vehicle
01:32 PM roycroft: so the cost of everything goes way up
01:32 PM roycroft: the shop asked about flushing and replacing the transmission fluid
01:32 PM roycroft: i said "not of it's clean"
01:33 PM roycroft: it holds 16 quarts
01:33 PM roycroft: that would be expensive to replace just to be replacing it
01:33 PM lcnc-relay: <skunkworks8841@> this is an automatic?
01:33 PM roycroft: yes
01:33 PM Rab: I'm in a similar boat, oil leak from the rear main seal in my RWD car. The seal is $10, replacing it requires removing the engine and transmission as a unit. (I've dropped the transmission before, but IMO it's actually easier to pull the whole thing.)
01:33 PM lcnc-relay: <skunkworks8841@> dads is a manual
01:33 PM roycroft: it was rebuilt about 10k miles ago
01:33 PM roycroft: i have receipts from the previous owner
01:34 PM roycroft: so it should be good to go for a long time
01:34 PM lcnc-relay: <skunkworks8841@> nice
01:34 PM roycroft: why the seal is failing is puzzling and a bit worrysome
01:34 PM lcnc-relay: <skunkworks8841@> diesles should last a long time..
01:34 PM roycroft: the vehicle has 375k miles on it
01:34 PM roycroft: so the engine is broken in now :)
01:34 PM lcnc-relay: <skunkworks8841@> right 🙂
01:34 PM roycroft: this is the 2nd generation 7.3l powerstroke
01:35 PM roycroft: arguably the best small diesel engine ever made
01:35 PM lcnc-relay: <skunkworks8841@> I think dads is a 6l - the yecky ones.. as far as I know
01:35 PM roycroft: it's the whole reason i bought the vehicle
01:35 PM roycroft: i got it with that engine for a gasoline engine price
01:36 PM roycroft: i told the shop when i dropped it off the other day what i paid for the pickup and their jaws collectively dropped
01:36 PM roycroft: it came with that recent tranny rebuild, new glow plugs and wires, and newly-rebuilt injectors
01:36 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/HfnwewEHWxkJTvyq9
01:37 PM lcnc-relay: <skunkworks8841@> (he has both volumes)
01:37 PM roycroft: mine's a 2001
01:37 PM roycroft: right before they went to the 3rd gen diesel engines
01:37 PM lcnc-relay: <skunkworks8841@> huh - I thought the 7.3's were after the 6.. I guess I don't know my history
01:38 PM roycroft: there were 7.3s in the 90s
01:38 PM roycroft: they were crap
01:38 PM roycroft: iirc the 6.0l and 7.3l both came out around the same time
01:38 PM lcnc-relay: <skunkworks8841@> ah.
01:39 PM lcnc-relay: <skunkworks8841@> I know the injectors on the 6l would get sticky.. Dad replaced them all and the truck ran really good after that. It was the best sounding truck imho.. The turbo whistle was pretty cool
01:40 PM roycroft: https://roycroft.us/New_Pickup.jpeg
01:40 PM roycroft: that's my rig
01:40 PM xxcoder: nice
01:40 PM roycroft: i have better tires on it now
01:40 PM lcnc-relay: <skunkworks8841@> nice - dads is falling apart.
01:40 PM roycroft: that's the only picture i have of it, and that was while it was still on the dealer lot
01:41 PM roycroft: i put running boards on it on day one, so i did not need a ladder to get into it
01:41 PM xxcoder: wise
01:42 PM roycroft: yeah, i don't know why they weren't there in the first place
01:42 PM lcnc-relay: <skunkworks8841@> lol - dads running boards fell off. That is why there is a whole frame and cab for a 'project'
01:43 PM roycroft: the dealer would not budge on price, and i almost walked away, but when i complained about the running boards he said he'd give me a pair as part of the deal
01:43 PM lcnc-relay: <skunkworks8841@> nice!
01:43 PM lcnc-relay: <skunkworks8841@> that is one way to handle it
01:43 PM roycroft: yeah
01:44 PM roycroft: i've never had a used car dealer so intransigeant on price before
01:45 PM roycroft: but in fairness, it was already a real steel - $6k less than it was worth - and the dealer had paid for the injectors and glow plugs, which was over $2k
01:45 PM roycroft: steal
01:45 PM roycroft: it was also real steel :)
01:45 PM xxcoder: steal of a steel
01:45 PM lcnc-relay: <skunkworks8841@> lol
01:45 PM rdtsc-w: if only last name was Steele :)
01:45 PM roycroft: but it seemed he was more into just refusing to haggle, period, than concerned about losing money
01:46 PM lcnc-relay: <skunkworks8841@> dad initally had an 83'ish with the 6.9 liter IH diesel...
01:46 PM lcnc-relay: <skunkworks8841@> we overhauled it once..
01:46 PM roycroft: he had sold it once but the buyer never paid for it (as in all the paperwork was done, down payment made, but the final payment not made, and the vehicle never left the lot)
01:46 PM roycroft: and he had had it for over a year
01:46 PM lcnc-relay: <skunkworks8841@> he drove that into the 2000's I think
01:46 PM roycroft: which is a *long* time on a used car lot
01:50 PM NetPipe: https://github.com/netpipe/HTMLBooks/releases/ neat because it can serach all pages at once. for making manuals and books
02:08 PM Tom_L: skunkworks, what is the ribbon connected to?
02:09 PM lcnc-relay: <skunkworks8841@> nvme
02:09 PM lcnc-relay: <skunkworks8841@> https://www.amazon.com/dp/B0F389CXSX?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
02:10 PM lcnc-relay: <skunkworks8841@> I didn't have a usb->nvme adaptor.. I had to pull the back off of a laptop here that had an nvme slot
02:11 PM lcnc-relay: <skunkworks8841@> an I5 my dad bought for my mom.. it is so slow and I remember that. It has spinning rust in it..
02:11 PM lcnc-relay: <skunkworks8841@> it seems to boot just slightly faster.
02:12 PM Tom_L: cool
02:12 PM Tom_L: i want to try that one of these days
02:12 PM Tom_L: is that the same as a M.2 slot?
02:13 PM Tom_L: looks like it
02:13 PM lcnc-relay: <skunkworks8841@> lol
02:13 PM lcnc-relay: <skunkworks8841@> Tom_L: what latency were you getting?
02:13 PM lcnc-relay: <skunkworks8841@> yes
02:13 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Rpi5/Rpi5_histogram2.png
02:13 PM lcnc-relay: <skunkworks8841@> The newer type?
02:14 PM Tom_L: i dunno, i have a samsung M.2 1g
02:14 PM lcnc-relay: <skunkworks8841@> oh - I forget I could run the base thread now.. let me do that.
02:14 PM Tom_L: i'm not using
02:14 PM lcnc-relay: <skunkworks8841@> what I linked to comes with a drive
02:14 PM Tom_L: ^^ those are good enough for anything
02:14 PM Tom_L: i saw that
02:15 PM Tom_L: how do you get 12 & lcnc on it?
02:15 PM lcnc-relay: <skunkworks8841@> 12?
02:15 PM Tom_L: debian 12
02:15 PM Tom_L: i haven't really looked into it
02:16 PM lcnc-relay: <skunkworks8841@> I am just running the image from the linuxcnc downloads
02:16 PM Tom_L: just installed it on the nvme?
02:16 PM lcnc-relay: <skunkworks8841@> says it is bookworm
02:16 PM lcnc-relay: <skunkworks8841@> yes
02:16 PM Tom_L: yes bookworm is 12
02:16 PM Tom_L: trixie is 13
02:16 PM lcnc-relay: <skunkworks8841@> ok - then - that is what the image is on the linuxcnc download site
02:17 PM Tom_L: that's what i've been using on the sd
02:17 PM lcnc-relay: <skunkworks8841@> I slapped the nvme in the open slot of the laptop - booted up - installed the raspberry pi imager and wrote the image to the nvme
02:17 PM Tom_L: do you use the rpi downloader to get it there?
02:17 PM lcnc-relay: <skunkworks8841@> ^^ yep
02:17 PM Tom_L: ok
02:18 PM lcnc-relay: <skunkworks8841@> it booted right up - didn't have to do anything else
02:18 PM Tom_L: i'd have to get an adapter for the pc
02:18 PM Tom_L: i have one with an M.2 slot but not sure which one it is
02:19 PM Tom_L: does it get in the way if you wanted to use the IO port?
02:19 PM Tom_L: ie spi
02:19 PM lcnc-relay: <skunkworks8841@> no - you can mount it on the top or the bottom. I have it mounted on the bottom
02:20 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Rpi5/pics/RPI5_spi_cable3.jpg
02:20 PM lcnc-relay: <skunkworks8841@> or - I suppose you could mount it away..
02:20 PM Tom_L: i'd have to loose the case
02:20 PM lcnc-relay: <skunkworks8841@> yes
02:20 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Rpi5/pics/RPI5_spi_cable4.jpg
02:21 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/ky1ZdToSUxeBY1Zq7
02:21 PM Tom_L: i like the case for testing since it somewhat protects the pi
02:21 PM lcnc-relay: <skunkworks8841@> right
02:34 PM Tom_L: https://52pi.com/collections/cases/products/52pi-aluminum-case-for-raspberry-pi-5-with-official-active-cooler-p33-m-2-nvme-m-key-poe-hat
02:34 PM Tom_L: case for nvme
02:34 PM Tom_L: a bit pricey
02:34 PM Tom_L: probably only fits their board
03:33 PM lcnc-relay: <skunkworks8841@> https://www.youtube.com/watch?v=orurGdrlzIs
03:33 PM lcnc-relay: <skunkworks8841@> a stuart platform on the end of their 'robot' arm.. (to stablize the end effector) neat idea
03:34 PM xxcoder: thats cool
03:34 PM xxcoder: tom yep likely bespoken. looks good though
03:47 PM lcnc-relay: <skunkworks8841@> the fan setup for the pie is nice. It is currently just slightly spinning while the latency test is running
03:57 PM Tom_L: cool... literally
04:08 PM lcnc-relay: <skunkworks8841@> (also running it at 3ghz)
05:24 PM JT-Shop: I should finish sharpening the chains
05:31 PM Tom_L: you have one of those oregon sharpeners?
05:31 PM Tom_L: makes short work of it
05:32 PM lcnc-relay: <skunkworks8841@> pff.... file is pretty quick..
05:32 PM lcnc-relay: <skunkworks8841@> 😉
05:32 PM Tom_L: maybe if you're out in the boonies
05:32 PM xxcoder: even with million teeth?
05:32 PM Tom_L: i keep plenty of spare chains
05:32 PM lcnc-relay: <skunkworks8841@> dad used to use what he called the 'mototool' to sharpen his chain saws..
05:32 PM lcnc-relay: <skunkworks8841@> then at some point - he just switched to files..
05:33 PM lcnc-relay: <skunkworks8841@> there are not that many teeth on a chain..
05:33 PM Tom_L: that's what dremel called em
05:34 PM JT-Shop: yup I have an oregon sharpener, I use a file in the field
05:34 PM JT-Shop: a 36" bar has a lot of teeth
05:34 PM Tom_L: i have a file too but am seldom 'in the field'
05:35 PM rdtsc-w: half of the teeth are 'push the chips out' teeth and not sharp at all
05:35 PM lcnc-relay: <skunkworks8841@> hmm - pretty sure it wasn't dremel.. maybe it was like kleenex and xerox..
05:35 PM lcnc-relay: <skunkworks8841@> it was about 3 inches in diameter and silver
05:37 PM JT-Shop: if half the teeth are dull the chainsaw will cut in a circle :)
05:38 PM rdtsc-w: does that make it a chain-circular-saw? :)
05:38 PM xxcoder: chainsaw-corer
05:38 PM Tom_L: without a kickback preventer
05:38 PM JT-Shop: it makes it an aggravating chainsaw
05:39 PM roycroft: i use a harbor freight sharpener for my chains
05:39 PM roycroft: and files in the field
05:39 PM roycroft: the hf one works ifne
05:39 PM roycroft: and it's cheap
05:39 PM Tom_L: being from oregon i would have suspected you having an oregon sharpener
05:39 PM roycroft: i have some oregon bars
05:39 PM xxcoder: roy is very sharp. makes sense
05:40 PM rdtsc-w: only ever used files... takes like 5min
05:40 PM roycroft: i have more echo bars than oregon bars, though
05:40 PM roycroft: but i think all my chains are oregon chains
05:40 PM JT-Shop: once you hit a rock it takes a lot longer than 5 min to sharpen a chain
05:41 PM roycroft: i just got a new bar the other day, but i have to return it
05:41 PM roycroft: it's a 12" bar, which i got because i wanted to use a chain saw for some of the joinery work on the roof frame
05:41 PM roycroft: but it doesn't fit right - it interferes with the cog
05:42 PM roycroft: that chainsaw came with an 18" bar, and can take up to a 30" bar, so maybe it just doesn't like short bars
05:42 PM rdtsc-w: got a 12" electric... wooohooo careful with that thing, it is very hungry
05:42 PM JT-Shop: that's a big power head to take a 30" bar
05:42 PM roycroft: i don't like electric chainsaws
05:42 PM xxcoder: only one I have is 3" lol
05:42 PM roycroft: they are too dangerous
05:43 PM roycroft: 65 cc
05:43 PM roycroft: and 30" is kind of pushing it
05:43 PM JT-Shop: my 391 takes up to 36" and that's what I keep on it
05:43 PM JT-Shop: my 291 has a 24" bar
05:43 PM JT-Shop: my 021 has a 14" bar iirc
05:43 PM roycroft: chainsaw chaps will do nothing to protect you from an electric chain saw
05:43 PM roycroft: be aware of thatr
05:44 PM xxcoder: yeah when I used that 3" saw I was being very careful. electric
05:45 PM JT-Shop: I have or had an electric but the chain was dull so I don't use it... not even sure if I still have it
05:46 PM rdtsc-w: wonder if the tooth design is more aggressive or what... easily outpaces the same size gas - very careful with it
05:47 PM JT-Shop: I should finish blasting the trailing arm
05:47 PM rdtsc-w: list of projects never ends :)
05:49 PM roycroft: electric chainsaws have no torque
05:49 PM roycroft: they make up for it by moving the chain about 2x as fast as a gas one
05:49 PM roycroft: they will cut through your chaps and your leg before you know what's happening
06:10 PM JT-Shop: Greenworks battery-powered chainsaws deliver 20% more torque and quicker, more efficient cutting than a 40cc gas chainsaw equivalent.
06:10 PM JT-Shop: Electric chainsaws like Greenworks are designed to be 20% lighter than gas chainsaws and produce 70% fewer vibrations, making them ergonomic and comfortable.
06:13 PM JT-Shop: they may have improved over the years...
06:13 PM * JT-Shop calls it a day
06:31 PM roycroft: but they are still faster
06:31 PM roycroft: and that still causes issues with ppe
06:32 PM roycroft: the best recommendation, of course, is to never cut into your chaps with either an electric or gas chainsaw
06:33 PM roycroft: but if you must, a gas saw is safer than an electric one
06:34 PM lcnc-relay: <skunkworks8841@> well - the spinning rust was definatly why this i5 was dead ass slow. The nvme is 1000 times better
06:34 PM xxcoder: yeah old drives was big slowdown when file accesses is needed
06:35 PM roycroft: btw, the shop just called and said that napa recommends that they send me to a transmission shop instead of selling them the seal
06:35 PM roycroft: they disagree, but the guy working on the vehicle hasn't worked on that particular transmission before, so he's checking with some other folks
06:35 PM roycroft: he thinks he can handle it fine
06:35 PM roycroft: and that napa are just being weird
06:36 PM roycroft: he also thinks that replacing the rear crankshaft seal would add a half hour to the job, and i've already priced the seal out at $40
06:36 PM roycroft: so if they do the job i'll have them do that seal as well
06:37 PM roycroft: since splitting and reinstalling the tranny is almost the entire job
06:38 PM roycroft: and for anyone who has ever cut a board too short, and when they recut it it's still too short, there is a fix for that now
06:39 PM xxcoder: 🧙
06:39 PM roycroft: https://www.youtube.com/watch?v=bgS6-O2APWY
06:40 PM roycroft: the duhwalt bs1000 board stretcher
06:40 PM xxcoder: lol
06:45 PM xxcoder: yt is trying that bs with "interruptions" with non-chrome
06:49 PM xxcoder: https://anycrap.shop/product/automatic-project-automator thought of that afer that ai video from that guy
07:26 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/ohUkPwr3Puw4N8fN9
07:29 PM xxcoder: weird
07:29 PM lcnc-relay: <skunkworks8841@> not the greatest rorschach test
07:39 PM lcnc-relay: <skunkworks8841@> wow - the computer is so much better.
07:47 PM lcnc-relay: <skunkworks8841@> I forget how crappy life was before ssd's.. But we didn't know any better
07:55 PM roycroft: i'm finishing up processing my third batch of books since the end of last week
07:55 PM roycroft: there are 60 books/batch, as the label sheets have 60 labels/sheet
07:55 PM roycroft: i'm finding books i haven't seen in years, and books i forgot i had
07:56 PM roycroft: this is one of those tasks that i do not enjoy doing at all, but i really enjoy the results
07:57 PM roycroft: that's why i'm so far behind, but also why i'm pushing to get it done now
07:58 PM Tom_L: skunkworks, going from a floppy to a 10m segate was a huge step then
07:59 PM Tom_L: also kindof an unusual histogram
08:03 PM lcnc-relay: <skunkworks8841@> I agree - but have seen similer
08:04 PM Tom_L: that was with the nvme?
08:04 PM lcnc-relay: <skunkworks8841@> yes
08:04 PM lcnc-relay: <skunkworks8841@> it is still running
08:05 PM Tom_L: will it still mount to a mesa card with that hat on?
08:05 PM Tom_L: the 7cxx ones
08:06 PM lcnc-relay: <skunkworks8841@> I don't know if I have seen them.. I have not used any of the serial boards.
08:07 PM lcnc-relay: <skunkworks8841@> the kit comes with enough standoffs to mount the drive either on the top - or the bottom of the pi
08:07 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Rpi5/pics/RPI5_spi_cable4.jpg
08:07 PM Tom_L: it has standoffs and the board mounts right by the ribbon
08:08 PM Tom_L: it would block the fan on top though wouldn't it?
08:10 PM lcnc-relay: <skunkworks8841@> I think there is enough room - it has to be higher than the usb plugs - which is atleast 1/4 higher than the fan
08:10 PM Tom_L: my fan hasn't run that much anyway
08:10 PM Tom_L: but in fairness i haven't abused it much
08:12 PM lcnc-relay: <skunkworks8841@> I do need a m.2 to usb though.. I don't want to pull a computer apart to flash the image.
08:12 PM lcnc-relay: <skunkworks8841@> this one cycles - very slow rpm when it is running
08:12 PM Tom_L: that may not be a bad idea here as well
08:13 PM lcnc-relay: <skunkworks8841@> and this is probably worse case.. overclocked and running the latency test
08:14 PM Tom_L: i'd probably get one that plugs like a thumb drive
08:15 PM Tom_L: over a corded one
08:16 PM Tom_L: https://www.amazon.com/GODSHARK-Adapter-Needed-Converter-Reader/dp/B07QSK16ZY
08:17 PM Tom_L: do you know what the 2230 2242 2260 2280 numbers are?
08:17 PM Tom_L: looks like it may be the ssd length
08:18 PM xxcoder: "Please note that it supports SATA-based B Key SSD only. DO NOT support M.2 NVME SSD. DO NOT support any PCIe NVMe based SSD. "
08:18 PM Tom_L: yeah
08:19 PM Tom_L: that probably adds more smarts to the card
08:21 PM lcnc-relay: <skunkworks8841@> Yah.. I have one but it only works on the older nvme's
08:21 PM lcnc-relay: <skunkworks8841@> This drive for the pie is keyed differently
08:22 PM Tom_L: is nvme different that a regular M.2 ssd?
08:23 PM lcnc-relay: <skunkworks8841@> Lol. I don't know. Never looked it up. I thought they were all nvme - just different versions
08:23 PM Tom_L: A "regular" M.2 SSD refers to an older type of M.2 drive that uses the slower SATA protocol, whereas an NVMe M.2 SSD uses the much faster PCIe-based NVMe protocol for better performance.
08:24 PM Tom_L: nvme is a protocol. M.2 is a form factor
08:24 PM lcnc-relay: <skunkworks8841@> Lol.. I was just reading something similar
08:25 PM Tom_L: the plugs are keyed different
08:26 PM Tom_L: seems you gotta research then buy
08:28 PM Tom_L: i'm not gonna run right out and get one but would like to try it some time
08:28 PM Tom_L: maybe by then they'll have nvme 3
08:30 PM Tom_L: so nvme is a 4-5x step up from sata
08:31 PM Tom_L: read/write speeds up to 5-6 times greater than the 600MB/s limit of a typical SATA III SSD
08:33 PM _unreal_: So I've done some amazing white marble milling as of late
08:33 PM _unreal_: I'll post photos at some point in time in the near future
08:34 PM _unreal_: Tom_L, I dont understand the need for extreme data transfer rate
08:34 PM _unreal_: I mean I get it but I dont under stand the need. unless people are dealing with transfering files or encoding files.
08:36 PM _unreal_: t4nk_fn, whats new
09:07 PM rdtsc: 2280 = 22mm x 80mm
09:10 PM infornography: Sometimes, You just want add some fractions into a metric print.... Because 3/8 of a mm dammit
09:11 PM lcnc-relay: <skunkworks8841@> That is why I bought the kit with the SSD 🙁
09:11 PM lcnc-relay: <skunkworks8841@> 🙂
09:12 PM Tom_L: _unreal_, no need for the speed however i presume nvme is more reliable than sd over a period of time
09:14 PM Tom_L: and besides... the cool factor
09:23 PM fywolfluff is now known as fluffywolf
09:30 PM _unreal_: so higher volume of re-writes
09:35 PM Tom_L: by design
09:35 PM Tom_L: sd are more a storage medium
10:38 PM lfluffywof is now known as fluffywolf
