12:33 AM CaptHindsight[m]: XXCoder: https://www.keronite.com/surface-technology/ when you need a more better coating for aluminum
12:43 AM XXCoder: less weight? antigravity coating?
12:43 AM XXCoder: i guess actually thinner coat
12:43 AM CaptHindsight[m]: but for a liquid coating I'd use an epoxy primer followed by urethane for 10 years of life
12:47 AM CaptHindsight[m]: this reminded me of that aluminum CNC mill kickstarter
12:48 AM XXCoder: yeah?
12:50 AM CaptHindsight[m]: https://www.kickstarter.com/projects/1260359869/swissmak-the-mill-turn-center-for-your-machine-sho
12:51 AM CaptHindsight[m]: aluminum box ways that were anodized
12:51 AM XXCoder: not too expensive
12:52 AM sensille: "Overlord Robotics Corporation"
12:52 AM XXCoder: not a successful project from comments
12:52 AM CaptHindsight[m]: We will be relocating our manufacturing operation to Taiwan in the next few months;
12:53 AM CaptHindsight[m]: and then they were never heard from again

01:50 AM travis_farmer[m]: G'Morning
02:07 AM -!- #linuxcnc mode set to +v by ChanServ
03:29 AM -!- #linuxcnc mode set to +v by ChanServ
04:21 AM Tom_L: morning
04:23 AM -!- #linuxcnc mode set to +v by ChanServ
04:28 AM Tom_L: 2-3" overnite
04:45 AM JT-Cave: about 6" and still snowing
05:28 AM -!- #linuxcnc mode set to +v by ChanServ
06:17 AM travis_farmer[m]: well, my ATC air line arrived last night, so i can at least run that on the machine, to the spindle. i will just have to have the other end run wild, as i don't know where the other end will be yet. i got about 30 feet of each. i need one run of the 6mm (unlock), and two runs of 4mm (lock and clearing). i am thinking of mounting the air solenoid, regulators, and filters right on the machine base, so the line runs are as short as
06:17 AM travis_farmer[m]: possible.
06:17 AM travis_farmer[m]: i was debating on mounting the air solenoid right on the gantry, but i don't think it is necessary
07:20 AM travis_farmer[m]: 14F out here in the shop... Brrrr....
07:36 AM travis_farmer[m]: well... this is off to a great start... the spindle manual said 6mm air-line for the spindle unlock... it is bigger... could be 8mm. so the fittings i have coming are wrong, as is the air-line i have now. maybe i can just get a 8mm to 6mm adapter and run the 6mm air-line...
07:39 AM rmu: measure once, cut twice
07:39 AM travis_farmer[m]: yeah, i should have confirmed before ordering. i just assumed the manual was correct
07:45 AM travis_farmer[m]: hmmm, let me get my measuring device...
07:49 AM travis_farmer[m]: yup, 8.13 mm id of the fitting, so 8mm tube...
07:53 AM travis_farmer[m]: just ordered 2x of these https://www.amazon.com/dp/B004M8T2IW (one extra, just in case)
07:55 AM travis_farmer[m]: so i can just run the 6mm line i have. cheapest way to save face...
08:04 AM rmu: it says one piece for us$4,05?
08:05 AM travis_farmer[m]: yes?
08:18 AM rmu: thats not cheap, proper price would be $4 for 20. IMHO. IANAL. YMMV. caveat emptor. standard disclaimer applies.
08:18 AM travis_farmer[m]: this is odd, running a test Gcode, and the program runs a few lines, then LCNC seems to halt, and qtdragon_hd field "MACHINE" says "Reading" and it just sits there...
08:18 AM travis_farmer[m]: well, they are ordered now...
08:25 AM * travis_farmer[m] uploaded an image: (363KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/AHXClwNOTbCHPTZkukXeutNY/Screenshot%20from%202023-01-25%2009-24-27.png >
08:25 AM travis_farmer[m]: that is what i am seeing...
08:31 AM -!- #linuxcnc mode set to +v by ChanServ
08:31 AM -!- #linuxcnc mode set to +v by ChanServ
08:32 AM rmu: what does DTG say
08:32 AM travis_farmer[m]: 0 on all axis
08:34 AM jpa-: travis_farmer[m]: does it always halt before first G1 move? maybe your spindle at speed signal is not hooked up correctly?
08:35 AM travis_farmer[m]: hmm, i disconnected the hardware at-speed, as i didn't think i needed it...
08:36 AM jpa-: i think if spindle is turned on in G-code and spindle.0.at-speed HAL signal is not high, linuxcnc will wait for it
08:36 AM travis_farmer[m]: ok, let me change a few things...
08:44 AM Tom_L: also, rearrange your post so the spindle is the first thing to come on before a move
08:45 AM Tom_L: that helped mine as before it wasn't quite up to speed
08:48 AM travis_farmer[m]: ok, fixed :-) i used near
08:48 AM Tom_L: as you should
08:48 AM travis_farmer[m]: before it was a hardware pin from the VFD
08:52 AM * JT-Woodshop hopes the snow melts fast
08:53 AM Tom_L: driving wasn't too bad here
08:53 AM Tom_L: kinda spotty
09:10 AM JT-Cave: 1.2.3 is up
09:11 AM Tom_L: what's it do different?
09:13 AM Tom_L: removed images
09:14 AM Tom_L: change the build version :)
09:18 AM unterhaus_: we're getting snow then rain later today. The dogs hate it because it's hard to eat iced over snow
09:18 AM Tom_L: i'll change mine and push it
09:19 AM Tom_L: building..
09:19 AM Tom_L: the deb still shows 1.2.2 here
09:27 AM Tom_L: dunno where you change that
09:32 AM JT-Cave: that's in the changelog
09:32 AM JT-Cave: it would help if I pushed the source...
09:33 AM Tom_L: :/
09:33 AM Tom_L: how do i undo my changes?
09:33 AM JT-Cave: pull and build again
09:34 AM Tom_L: ok
09:34 AM Tom_L: did you change the ver on the screen header?
09:34 AM Tom_L: yup
09:38 AM JT-Cave: changed the docs too!
09:38 AM Tom_L: building
09:40 AM JT-Cave: ok
09:49 AM Tom_L: JT-Cave, #88 ready
09:54 AM JT-Shop: thanks
09:54 AM JT-Shop: me got a head full of snow falling off the shop overhang
09:55 AM Tom_L: fun
10:01 AM JT-Shop: heavy wet snow
10:01 AM travis_farmer[m]: lol, i got that the other day. a little cold down the back of the neck ;-)
10:01 AM Tom_L: melting here
10:02 AM JT-Shop: melting here too 34°F and sun is mostly out
10:03 AM Tom_L: says it's 30 here but the sun is out
10:05 AM JT-Shop: lcnc is marked for auto removal from testing due to the python3-opengl bug
10:05 AM Tom_L: that's not good
10:11 AM Tom_L: ok headin out again
10:59 AM JT-Shop: WOW UPS delivered my package! He had to walk up the driveway for sure, too many cedar and juniper trees hanging low in the driveway
11:02 AM * JT-Shop attempts to get some work done
11:49 AM * travis_farmer[m] heads out to shop to see if he can install qtcreator, and make a custom qtdragon_hd page/panel with it...
12:06 PM * JT-Shop gives up trying to get any work done and wanders inside to take a nap
12:12 PM * JT-Cave didn't realize qtdragon was written in C++
12:13 PM travis_farmer[m]: i thought it was pyqt5 and python
12:14 PM JT-Cave: why are you using qtcreator?
12:14 PM JT-Cave: that's C++
12:15 PM travis_farmer[m]: dunno, i just was told it was pyqt5 and python, here: https://forum.linuxcnc.org/qtvcp/48061-how-to-make-my-own-custom-page-for-qtdragon-hd
12:15 PM JT-Cave: if it's pyqt5 you use Qt 5 Designer
12:16 PM roguish[m]: it's pyqt5, and one uses qt designer.
12:16 PM JT-Cave: the last post even says "I don't think you want qtcreator. You want qtdesigner. To get that, you have to install pyqt5. You get the linuxcnc widgets when you install qtvcp. You will also need to run python3, not python2. "
12:17 PM roguish[m]: sorry for jumping in, but I've been going down that road a while now.
12:17 PM JT-Cave: Qt Designer
12:17 PM JT-Cave: sudo apt install qttools5-dev-tools
12:17 PM roguish[m]: there is an install script burried deep that will install everything.
12:17 PM * JT-Cave takes a nap now
12:18 PM roguish[m]: see this https://forum.linuxcnc.org/qtvcp/38414-installing-qtvcp
12:19 PM * travis_farmer[m] just realized he was going out to shop, but got distracted... ;-)
12:30 PM travis_farmer[m]: script is running...
12:33 PM travis_farmer[m]: ok, that's done :-)
12:35 PM travis_farmer[m]: where is qtdragon source on disk? or is it?
12:39 PM travis_farmer[m]: found it
12:50 PM * travis_farmer[m] wishes he still had a test setup of LinuxCNC on a computer inside... it is cold out here... ;-)
12:51 PM roguish[m]: travis_farmer: ya gotta really rtfm on this one.
12:52 PM travis_farmer[m]: yeah, i haven't touched anything yet, just poking around
01:11 PM travis_farmer[m]: yeah, maybe i will leave well-enough along on that. i don't even know enough python to get myself in trouble... i think if i want status readouts on things from Arduino data, i will just use a Nextion HMI tft screen. i have one available, though i am unsure how it will like the cold... my computer monitor seems fine, so... there you have it, i guess
01:15 PM Tom_L: put a couple crt screens out there
01:41 PM travis_farmer[m]: really, CRT screens? ;-)
01:51 PM roguish[m]: travis_farmer: ya need a decent display. go dumpster diving..... check the local electronic recycle places. sometimes they'll sell stuff like monitors or tvs really cheap..... i just picked up a good 27" monitor for $50
01:54 PM solarwind: Guys, I got some cheap FPGA PCIe cards working with ultra low latency
01:54 PM travis_farmer[m]: i have a good display for LCNC... and an Arduino bairly runs a computer monitor, hence why i noted the use of a Nextion HMI screen. it is a 7" (diagonal) screen that is programable, and the Arduino only has to send the telemetry to it, rather than worry about drawing the graphics
01:54 PM solarwind: I'm going to make some alternative hardware to the MESA cards
01:54 PM solarwind: fully open source
01:54 PM solarwind: we'll see if there's any interest
01:55 PM XXCoder: hopefully easier to source parts
01:55 PM solarwind: I'm seeing < 5µs latency from RTAI to the card and back
01:55 PM solarwind: XXCoder that's the plan
01:55 PM XXCoder: and around as cheap
01:55 PM solarwind: yeah that's a hard requirement
01:55 PM solarwind: If I can't do it for hobbyist affordable prices, I won't even bother
01:56 PM XXCoder: cool
01:56 PM travis_farmer[m]: just be careful, pcw-home may send his henchmen over to have a word with you ;-)
01:56 PM solarwind: That's 5µs worst case round trip latency from external interrupt with no optimization
01:57 PM solarwind: travis_farmer[m] I would love to collaborate with pcw--home
01:57 PM solarwind: but it looks like he's been super busy reworking his designs due to the chip shortage
01:57 PM travis_farmer[m]: lol, i meant to rough you up ;-) (kidding of course)
01:59 PM zephyr9900: solarwind: are you going to us an FPGA? I was wondering if you could do this with a processor like the STM32F4xxxx using a NUCLEO board as a starting point and using some of the STMBL firmware since it already knows how to talk to linuxCNC using SSERIAL
02:00 PM solarwind: zephyr9900 yes FPGA + processor
02:00 PM solarwind: you need the FPGA to talk on the PCIe bus
02:00 PM solarwind: But it'll either be a soft core or ZYNQ FPGA with dual ARM running at 800MHz
02:00 PM zephyr9900: I also thought it would be cool to use LBP protocol over ethernet
02:00 PM solarwind: it'll be able to do real time EtherCAT as well
02:01 PM solarwind: it'll offload and fully bypass ethernet stack on the host
02:01 PM solarwind: I already got that logic working
02:01 PM zephyr9900: So you already have a FPGA etherCAT MAC implemented?
02:01 PM solarwind: yes
02:02 PM zephyr9900: cool
02:02 PM solarwind: well the EtherCAT is just a very simple protocol
02:02 PM solarwind: it's literally raw ethernet frames
02:02 PM zephyr9900: yes
02:02 PM solarwind: it's canopen over ethernet pretty much
02:02 PM zephyr9900: but it needs to modify on the fly
02:02 PM solarwind: not the master
02:02 PM solarwind: only the slaves need to do that
02:02 PM zephyr9900: right
02:03 PM zephyr9900: you have FPGA Ethercat MAC?
02:03 PM solarwind: yes, that's provided by Xilinx/opencores
02:03 PM solarwind: that's easy
02:03 PM zephyr9900: Ahh sure
02:03 PM zephyr9900: I need to converse with you smart guys more!
02:04 PM solarwind: D: not that smart, just spent a lot of time skipping school and teaching myself
02:04 PM zephyr9900: = pretty smart
02:06 PM zephyr9900: I am interested in your project!
02:06 PM solarwind: well it'll be fully open source so I'll publish posts as I go
02:06 PM zephyr9900: :-)
02:07 PM solarwind: biggest challenge will be finding vendors for appropriate FPGAs not tripling the price due to greed
02:07 PM solarwind: but we know it's posisble, because well: https://www.aliexpress.com/item/4001125245990.html
02:08 PM zephyr9900: sensille found some cheap FPGA boards from china for lighting you know about those right?
02:16 PM travis_farmer[m]: hmmm, now i gotta find a use for my THCAD-10, now that i have ModBus control of my VFD...
02:20 PM JT-Shop: sell it
02:20 PM travis_farmer[m]: know anybody that needs one?
02:20 PM JT-Shop: put it on the forum, I'm out of stock
02:21 PM travis_farmer[m]: ok, will do at some point. :-)
02:28 PM roycroft: travis_farmer: you make signs, do you not?
02:28 PM travis_farmer[m]: when my machine is usable i will, why?
02:29 PM roycroft: what software do you use to generate the gcode?
02:29 PM roycroft: signmaking is going to be a part of my business
02:29 PM roycroft: (i won't encroach on your territory)
02:30 PM travis_farmer[m]: JT put me on a program called F-engrave
02:30 PM roycroft: ok, i'm familiar with that
02:30 PM * JT-Woodshop replaced the FH socket screws with FH Torx screws and changing jaws is so much easier
02:31 PM travis_farmer[m]: when i can afford it, i plan to step up to Vetric VcarvePro
02:31 PM JT-Woodshop: on the patriot chuck
02:31 PM roycroft: it makes that much of a difference?
02:31 PM JT-Woodshop: yup
02:31 PM roycroft: travis_farmer: i'm going to get one of the vectric products
02:32 PM roycroft: probably not full aspire, at least not at first
02:32 PM JT-Woodshop: got a T handle T-30 to use
02:32 PM travis_farmer[m]: yeah, they are pricey ;-)
02:32 PM roycroft: i don't need the 3d capabilities right now
02:32 PM roycroft: and may never
02:32 PM * JT-Woodshop goes to clean chicken poop
02:33 PM roycroft: since there's a zero-penalty upgrade path, i'll buy what i need immediately, and upgrade later if needed
02:39 PM roycroft: yeah, vcarve pro is the product i plan on starting with
02:39 PM * roycroft has the $700 for it already, but wants to wait until he has the cnc router built before buying it
02:41 PM travis_farmer[m]: as cold as it has been, kinda thinking of robbing the furnace from my 5th wheel camper to mount in my CNC shop... it is only 34Kbtu, but it is a lot more than the diesel heater in there now...
02:46 PM travis_farmer[m]: i will have to measure it and see if it would fit in an existing hole (cargo door), or if i have to make a new hole... this shop is only temporary, until i get my bigger shop done, but i need the heat.
02:47 PM CloudEvil: Heated clothing may be another option
02:47 PM travis_farmer[m]: too expensive
02:48 PM roycroft: cheaper than heating a holey shed
02:48 PM travis_farmer[m]: the shed isn't holey... the hole i speak of has a cargo door over it now
02:50 PM travis_farmer[m]: the diesel heater is only 17Kbtu, so it really hasn't got the power to heat much
02:55 PM * JT-Shop clocks out and heads to the other shop
03:15 PM Tom_L: kid is complaining he has to drill 165 holes in a 6" 9k lb alum plate to hold it for machining
03:15 PM Tom_L: 345" long
03:17 PM XXCoder: cant automate that?
03:17 PM Tom_L: the machine drills em but they have to be cleared for bolts etc
03:17 PM Tom_L: was on the phone with him a bit
03:17 PM XXCoder: ahh ok
03:19 PM Tom_L: must be a bit ominous standing under that 3 head gantry clearing chips
03:19 PM XXCoder: I bet. hope it has ability to lock out green button?
03:20 PM XXCoder: not whole machine lockout just block off green button while machinist is working in something inside machine workspace
03:20 PM Tom_L: the workspace is the whole building...
03:20 PM XXCoder: workspace I mean inside milling area for machine
03:21 PM XXCoder: my cnc router is 300x240x50mm workspace for example
03:22 PM Tom_L: while i was there you couldn't really tell if it was moving or not but it was
03:23 PM * travis_farmer[m] wonders what his 93 year old granny will be making for supper tonight...
03:46 PM Tom_L: XXCoder, http://tom-itx.no-ip.biz:81/~webpage/cnc/cincinnati/Material_block.jpg
03:47 PM XXCoder: nice idea, bottle cap
03:47 PM Tom_L: all holddown bolts
03:48 PM Tom_L: yeah
03:48 PM XXCoder: i still remember that first time that I tasted, snorted, put it on eyes, some coolant
03:48 PM XXCoder: it was all at same time, by sprayer hose breaking
03:48 PM Tom_L: yummy ehh?
03:49 PM XXCoder: lol didnt taste like much, thankfully it was only small amount and i spat it out right away, then cleared nose
03:53 PM pjm_ is now known as pjm
03:54 PM Tom_L: XXCoder, aparently the programmer got the hole pattern wrong in the machine plate
03:55 PM Tom_L: not sure what they did to fix it..
03:55 PM XXCoder: ouch lol. if they havent cut edges they might have simply offset the edges
03:55 PM Tom_L: the plate under the block
03:55 PM XXCoder: oh aligning for bolt on
03:56 PM Tom_L: yeah
03:56 PM XXCoder: forklift? lol
03:56 PM XXCoder: precision placement by forklift lol
03:56 PM Tom_L: most of his parts are crane loaded
03:56 PM XXCoder: or more likely gantry lifted
03:56 PM Tom_L: there's a gantry above the machine
03:57 PM XXCoder: hmm with bunch of people they may be able to align one bolt hole, then turn to bolt on oppositing corner
03:57 PM XXCoder: then rest of it
03:57 PM Tom_L: i know at the previous shop, he did it all himself
03:58 PM Tom_L: he had a helper but the helper was worthless
03:58 PM Tom_L: got the block rocking with the crane control
03:58 PM Tom_L: one of the many reasons he left there
03:59 PM XXCoder: geez
03:59 PM XXCoder: yeah its often people who make shit job ok and amazing job shit
04:00 PM Tom_L: he was actually making the wing spars at the other place this part fits on
04:00 PM Tom_L: wing spar caps
04:01 PM Tom_L: one reason he was on the machine his first day there
04:01 PM Tom_L: ...yeah yeah... i got this..
04:02 PM Tom_L: much better environment
04:02 PM Tom_L: i met a few of the guys
04:03 PM XXCoder: nice
04:03 PM XXCoder: i remember the place I interviewed at before i got hired on next one
04:03 PM XXCoder: shop was very dim, chips everywhere
04:04 PM XXCoder: concerete glossy (olviously coolant sprayed often and not cleaned)
04:04 PM XXCoder: they didnt think deaf person can work on cnc machines (while I was literally doing everything setup and run on training job place lol)
04:04 PM XXCoder: so yeah glad I didnt go there
04:07 PM XXCoder: that job i worked 5 years at, i was supposed to be hired for deburring dept, but one cnc machinist was fired and other one quit over it
04:07 PM XXCoder: so they hired me for machining, and im so glad for it. i did work at deburr once a while, and its really bad for me
04:08 PM Tom_L: debur is a shit job
04:08 PM XXCoder: yeah. they had some guy work there for many many years
04:08 PM Tom_L: i suppose some would like it
04:08 PM XXCoder: he retired short time after I was laid off
04:09 PM XXCoder: guy barely talks at all, think hes autistic, but nice guy
04:14 PM JT-Woodshop: I was hired as a mechanic at Atlas Steel & Wire but a tool maker missed a lot of time and the supervisor remembered I was and Outside Machinist at the ship yard and thought I was a machinist
04:15 PM JT-Woodshop: so I got the job in the tool shop grinding cutters for the nail machines
04:15 PM Tom_L: well you were...
04:15 PM JT-Woodshop: same as millwright I think, installing machinery
04:17 PM XXCoder: interesting
04:18 PM JT-Woodshop: the guy in the tool shop Martin W. told me the first day I'll show you how to do cutters but not grippers
04:19 PM JT-Woodshop: challenge accepted, I learned how when he wasn't in the shop lol
04:20 PM otisa[m] is now known as otisa5329[m]
04:20 PM XXCoder: nice lol
04:22 PM JT-Woodshop: I found a Wafios book about grippers and after a while knew why his didn't work well
04:23 PM JT-Woodshop: I would snicker when they would bring new grippers back because they didn't work
04:23 PM Tom_L: ...here try these..
04:23 PM JT-Woodshop: one day he said "you make them"
04:24 PM JT-Woodshop: so we switched placed then I developed my own lapping pin that worked better than the Wafios lapping pins
04:24 PM JT-Woodshop: places
04:24 PM XXCoder: pin to lap the grinder wheel?
04:25 PM JT-Woodshop: the grippers are carbide so you lap them with diamond grit and a pin shaped the way you want the final shape
04:25 PM JT-Woodshop: first you lap them round and the depth you want then you lap the barbs in and the neck
04:27 PM XXCoder: well nice that you figured it :)
04:37 PM roguish[m]: JT-Woodshop: been thread milling an internal m28x1.5 not too bad. last pass made it just a bit too loose. but that's easy to fix.
04:39 PM JT-Woodshop: the Z is not accurate enough on the BP knee mill to thread mill...
04:39 PM JT-Woodshop: mill touch can do it but the BP can't lol
04:40 PM roguish[m]: oh, the z on your BP is probably the quill, right?
04:41 PM Tom_L: roguish[m], how many passes do you make?
04:41 PM JT-Woodshop: yup, the connection to the servo is pretty weak
04:41 PM JT-Woodshop: I should make a new adapter with wider footprint
04:42 PM roguish[m]: i did like 7 passes. crawling to the od very slow. and went just a bit too far.
04:42 PM roguish[m]: i'll do another and see if I can get it right with 3 or 4 passes.
04:43 PM roguish[m]: this is on my little PM940. fully cnc, dovetail ways. ball screws
04:44 PM Tom_L: i usually did mine in 2 passes maybe 3
04:44 PM roguish[m]: i'm chicken
04:44 PM Tom_L: once it was set
04:45 PM Tom_L: you think about it, that cutter isn't cutting hardly any material
04:45 PM roguish[m]: yeah, but just a thou or 2 makes a pretty significant difference
04:45 PM Tom_L: production runs them in a single pass at full bore
04:46 PM Tom_L: yeah i learned that early on :)
04:46 PM roguish[m]: hope so

04:56 PM XXCoder: building it up
04:57 PM XXCoder: did you run it in lathe already? i notice round surfaces
04:58 PM JT-Woodshop: yep, several times
04:59 PM Tom_L: getting there
04:59 PM JT-Woodshop: took 3 setups to get the base ready
04:59 PM XXCoder: so basically some pre-ops to make final lathe stage easier?
04:59 PM JT-Woodshop: remaking the next ring... first one was 1/2" too big on the id
05:00 PM Tom_L: save it for another project
05:00 PM JT-Woodshop: once I get the bottom to chuck up on the ID I can take it off and put it back on
05:00 PM JT-Woodshop: bigger bowl lol
05:00 PM XXCoder: or use it in rings to make a clock
05:00 PM JT-Woodshop: it's got 12 segments...
05:01 PM XXCoder: even better if its "invisible clockworks" clock. with gearings hidden in ring, and using arms on rotating glass
05:01 PM ellemoeiselleva is now known as ellemoe
05:01 PM ellemoe is now known as elleva
05:05 PM Tom_L: i forget who but somebody on irc was getting pen innards and making pens
05:06 PM JT-Woodshop: pen turning is a beginner project
05:08 PM Tom_L: with segments?
05:08 PM roycroft: i never got interested in making pens
05:08 PM JT-Woodshop: hmm that would be difficult for sure
05:08 PM Tom_L: matching bowl, pen sets :)
05:09 PM XXCoder: matching wood car
05:09 PM JT-Woodshop: I can't make anything match lol

05:10 PM JT-Woodshop: nice, they should have painted it blue...
05:10 PM Tom_L: i was gonna say..
05:11 PM XXCoder: lol
05:11 PM XXCoder: if you make car out of wood, then the wood look is the point
05:12 PM Tom_L: that's a ferari though, not a vette
05:12 PM JT-Woodshop: a woody
05:12 PM JT-Woodshop: yup
05:12 PM JT-Woodshop: damn windblows pc in the machine shop I need to format the hd and reinstall windblows 7
05:13 PM JT-Woodshop: https://forum.linuxcnc.org/10-advanced-configuration/48047-0-005-error-randomly-accumulating-over-30-000-inch-travel-solutions-etc#262877
05:15 PM Tom_L: that's like a 2 day process..
05:15 PM JT-Woodshop: it has 4 partitions so I need to format the disk then install windblows 7
05:16 PM JT-Woodshop: I think I'll boot up to a linux cd and format
05:16 PM JT-Woodshop: or freedos
05:17 PM Tom_L: ntfs?
05:17 PM JT-Woodshop: I knew it was going to be a PIA when I started lol
05:17 PM JT-Woodshop: I think so
05:17 PM XXCoder: sudo dd if=/dev/zero of=/dev/sda lol
05:17 PM JT-Woodshop: yup
05:18 PM JT-Woodshop: that takes all day lol
05:18 PM XXCoder: not if you use larger buffer
05:18 PM Tom_L: disadvantage of TB drives
05:18 PM XXCoder: like 4M or whatever
05:18 PM JT-Woodshop: it has to be a multiple of 512 II
05:18 PM JT-Woodshop: RC
05:18 PM XXCoder: for best speed yeah
05:19 PM XXCoder: you can use any number but yeah if not aligned it'd take bit more time
05:19 PM JT-Woodshop: hmm the hens are on the roost
05:19 PM Tom_L: makes the block size odd though doesn't it?
05:20 PM XXCoder: its write buffer so it dont really matter
05:20 PM XXCoder: aligning it to block size means it dont have to do partial block write
05:20 PM XXCoder: default single block size is very slow
05:21 PM XXCoder: *buffer
05:22 PM XXCoder: https://www.grimoire-command.es/2020/dd_buffer_size.html
05:22 PM XXCoder: notice that 1M buffer is over 3x faster
05:23 PM XXCoder: I usually use 4M because my pc got oceans of ram
05:24 PM XXCoder: even old pc 1 gb ram still plllllenty of room
05:30 PM XXCoder: one site suggests this
05:30 PM XXCoder: dd bs=$((512*2048*32)) if=/dev/source of=/dev/target
05:30 PM XXCoder: its 512 block aligned buffer size
05:33 PM JT-Cave: sudo dd if=full/path/to/iso/file of=/dev/sd? bs=8192 status=progress
05:34 PM XXCoder: 8k only small boost
05:35 PM XXCoder: sudo blockdev --getbsz /dev/sda
05:36 PM JT-Cave: I don't see a buffer size in that link
05:36 PM XXCoder: thats a way to get block size. my sdd is 4096
05:36 PM XXCoder: same for my spinning rust
05:36 PM XXCoder: second comman does have bs=1M
05:37 PM XXCoder: thats why it had write speed of 8.8 mb/s compared to first of only 2.5 mb/s
05:37 PM JT-Cave: now I see bs=1M
05:38 PM JT-Cave: I usually put it at the end lol so that's where I was looking
05:38 PM XXCoder: yea me too lol had to look for few seconds before i shared link
05:49 PM * JT-Cave calls it a night
06:27 PM elleva is now known as heartcore
10:46 PM roycroft: i was finally able to test my vinyl cutter
10:46 PM roycroft: it seems to work, but the sample vinyl rolls that came with it are pretty crappy
10:47 PM roycroft: i need to get some decent vinyl and dial in the machine
10:47 PM XXCoder: nice
10:49 PM roycroft: the software is kind of funky too
10:49 PM roycroft: but i expected that
10:49 PM roycroft: i'll get it all sorted
10:59 PM roycroft: i guess i should start by figuring out what kind of vinyl is good for each of my applications
11:00 PM XXCoder: yeah, bunch of testing needed :D
11:31 PM roycroft: it looks like i just need two types of vinyl
