03:53 AM mits[m]: :moin:
04:03 AM travis_farmer[m]: G'Morning, my ATC spindle is supposed to arrive today :-)
04:30 AM Tom_L: morning
04:50 AM mits[m]: Hey, so I'm using compensation.py and it works pretty well... but if I want to touch off on Z how should I be doing it?
04:51 AM mits[m]: Should I be turning off the compensation before setting a value
04:51 AM mits[m]: I can't tell from the behavior of the system whether it takes the value before or after the compensation
05:11 AM JT-Cave: morning
05:57 AM travis_farmer[m]: just checked my CNC parts shipments... i have packages coming from UPS, FedEx, and USPS... i wonder what would happen if they all showed up at once... ;-)
05:58 AM CloudEvil: Fight.
06:00 AM travis_farmer[m]: if they do, you can be assured i video it for YouTube ;-)
07:12 AM mits[m]: You forgot to order something via DHL
07:17 AM travis_farmer[m]: DHL doesn't come to maine. it gets transferred to FedEx or USPS
07:18 AM Tom_L: first of all USPS will lose it, UPS will be in another state and FedEx will beat the crap out of the box
07:18 AM Tom_L: should have used Amazon prime
07:18 AM Tom_L: it would have showed up ahead of schedule with a smile
07:19 AM travis_farmer[m]: well, Tom_L is a bright ray of sunshine this morning ;-)
07:19 AM travis_farmer[m]: amazon prime uses UPS in maine
08:08 AM ellemoeiselleva is now known as ellemoe
08:12 AM travis_farmer[m]: USPS just showed up with 3 items. an air solenoid for my spindle, BT30 tool holder vice, and a THCAD-10 from Mesa. just like my birthday, even though it is not my birthday. :-)
08:16 AM JoseIgnacioRomer: some packages it does seem like they employ ace ventura
08:50 AM unterhaus: Anything amazon sends ends up with USPS here, even if they originally send it out ups. The UPS drivers have the option of dumping parcels at USPS if they don't want to deliver them
10:33 AM unterhaus: roycroft, spotted a new abomination "Slab cut with waterfall edge"
10:34 AM unterhaus: you see them assembled out of pieces, this was cut out of a log
10:58 AM * roycroft wonders what this world is coming to
10:58 AM roycroft: next thing you know, dogs and cats will be living together in harmony
11:51 AM * travis_farmer[m] eagerly awaits UPS... the more you want something, the longer they take to deliver...
12:18 PM unterhaus: I just got some parts that were supposed to come with something I ordered and I feel guilty for asking for them
12:21 PM travis_farmer[m]: not sure i understand
12:26 PM unterhaus: I ordered something and it came with some small parts missing
12:26 PM unterhaus: so I asked for them
12:27 PM unterhaus: strangely, the part that would have been the biggest pain for me to get was a 5mm flat head screw
12:28 PM travis_farmer[m]: oh, i see now. yeah, the spindle i ordered, said in the ad that they would email me the english manuals... i had to ask for those, as it went days...
12:38 PM travis_farmer[m]: geez, as much shipping as i paid for on that spindle, you would think UPS could display the "follow my delivery" map ;-)
12:39 PM roycroft: you have to sign up for a ups account to get that feature
12:39 PM travis_farmer[m]: i have one
12:39 PM roycroft: i cancelled mine
12:39 PM roycroft: they charged me for a shipment from some warehouse in tennessee to another warehouse in tennessee
12:39 PM roycroft: and when i disputed it they said "it was shipped with your shipper number, therefore you are responsbile"
12:40 PM roycroft: i had to initiate a chargeback with my credit card issuer to get my money back
12:40 PM roycroft: and ups told me that if did not provide them with a valid payment method i could not have a ups account, even for tracking
12:40 PM roycroft: so i told them to cancel it
12:40 PM roycroft: and they refused to cancel it
12:41 PM roycroft: so i cancelled the credit card i had on file with them and got a new one
12:41 PM roycroft: and they started nagging me about not having a valid payment method
12:41 PM roycroft: i finally blackholed their emails
12:41 PM roycroft: and this is why i do not ship with ups any more
12:42 PM travis_farmer[m]: sounds spiteful ;-) though not for a bad reason...
12:57 PM roycroft: spiteful on whose part?
01:12 PM Alden[m]: So, I’m going to use a floating head and thcad-10. I’m use to having to set up plasmac, but it’s been a bit. Is plasmac outdated or would I use something else to configure the thcad-10 and floating head?
01:18 PM JT-Shop: I use a subroutine and know nothing about plasmac just because it's too complicated
01:20 PM travis_farmer[m]: there is the HAL component thc, that JT wrote, that may help too...
01:20 PM roguish[m]: JT-Shop: good afternoon. got a question on your gcode generator.... about the 'face' routine
01:25 PM Tom_L: travis_farmer[m], ups will deliver when they're done playing football with your package
01:25 PM travis_farmer[m]: oh god, don't make me throw up with worry! i get worried enough as it is ;-)
01:26 PM Tom_L: don't worry, they'll tape it up when they're done
01:28 PM JT-Shop: lol
01:30 PM Tom_L: jt anything worth building today?
01:30 PM travis_farmer[m]: yeah, you can build my confidence...
01:30 PM Tom_L: i was trying
01:32 PM Alden[m]: @JT-Shop what is a subroutine and how does it work? Where would I learn about that and how to use it or implement a subroutine?
01:32 PM JT-Shop: Tom_L, no
01:32 PM Alden[m]: Oops
01:32 PM Tom_L: http://linuxcnc.org/docs/stable/html/gcode/o-code.html
01:32 PM Tom_L: alden
01:33 PM JT-Shop: Alden[m], https://gnipsel.com/shop/plasma/plasma.xhtml touchoff.ngc
01:34 PM Tom_L: Alden[m], call the subroutine the same name as the file you put it in
01:34 PM JT-Shop: you pass (#1 pierce height, #2 pierce delay, #3 cut height)
01:34 PM Alden[m]: Thank you, okay I’ll look into it. What about configuring the THCAD-10
01:35 PM JT-Shop: G1 Z0.070 (Raise up to Z0) this distance depends on the hysteresis of your floating head switch
01:36 PM JT-Shop: nothing to configure on the THCAD-10, just note the freq on the label and apply that to the thc comp
01:36 PM JT-Shop: http://linuxcnc.org/docs/stable/html/man/man9/thc.9.html
01:37 PM roguish[m]: JT-Shop: hey, with your face routine, if I set the top height to say 2.0, and want to skim off .25, it won't really do it. it wants the cut to be -, like less than zero.....
01:43 PM JT-Shop: I'll have to look at it
01:44 PM JT-Shop: I usually have z0 as the top of the material
01:44 PM JT-Shop: bbl
01:44 PM roguish[m]: hey thanks man. if ya get it to work, take a screen shot of how
01:51 PM * travis_farmer[m] thinks he paid $82.86 for something he didn't need...
02:41 PM Plaid: roycroft: What's funny is that there's basically no checking of shipper numbers. it was probably a typo
02:41 PM roycroft: yes
02:41 PM roycroft: but they don't care
02:42 PM roycroft: all they care about it collecting money
02:42 PM Plaid: probably someone did a 3rd party billing shipment, typo'ed your number somewhere in the chain, and you got billed
02:42 PM roycroft: yup
02:42 PM Plaid: You can disable 3rd party billing if you want
02:42 PM roycroft: i never thought it was malicious
02:42 PM roycroft: i asked them that and they told me that if i have a shipper number and someone uses it i get billed
02:43 PM roycroft: i would have been fine with just disabling third party billing
02:43 PM Loetmichel: well, sometimes its good to live in germany. every charge on the account can be taken back for 30 days
02:43 PM Plaid: The whole shipping system for UPS and fedex is rife with security holes.
02:43 PM roycroft: indeed
02:43 PM Loetmichel: (only charges though, not things you paid yourself)
02:43 PM roycroft: and when i start shipping product again on a regular basis i'm not sure what i'm going to do
02:43 PM roycroft: schlepping it to the ups store every time is not feasible
02:44 PM roycroft: not to mention the shipping cost itself would be a lot more than doing it on an account
02:44 PM Loetmichel: hmm, here at the company UPS comes by and collects.
02:44 PM Plaid: roycroft: What do you ship (I specialize in writing shipping automation)
02:44 PM roycroft: they do here as well, if one has an account
02:44 PM roycroft: plaid: i'll be manufacturing small wooden (mostly) products
02:45 PM Plaid: Packages/day?
02:45 PM roycroft: so mostly smallish boxes, and mostly <5kg
02:45 PM roycroft: hopefully 20-30/day eventually, at least
02:45 PM Plaid: US?
02:45 PM roycroft: 2-3/week at the start, most likely
02:45 PM roycroft: for the most part
02:45 PM roycroft: although i don't mind shipping internationally, and have done so many times in the past
02:46 PM roycroft: i'm pretty accustomed to bills of lading and customs declaration forms
02:46 PM Plaid: Value of merchendise?
02:46 PM roycroft: <$1000
02:46 PM roycroft: many <$100
02:46 PM Plaid: Okay, inital launch, you can get a ups or fedex account, and find a local dropoff box. They are picked up from on a daily basis, at a known time, so as long as you make it to the drop box in time, it'll make it simple for you.
02:47 PM roycroft: the fedex ground depot is fairly near my house, and right on my way into downtown
02:47 PM roycroft: i figured dropping off there would be pretty straightforward
02:47 PM Plaid: But there are drop boxes all over the place that are public.
02:47 PM roycroft: well most of my stuff would not fit in a drop box
02:47 PM Plaid: Just in random business parks, etc.
02:48 PM Plaid: Rough size?
02:48 PM roycroft: but the local mailing companies generally allow pre-labeled drops for both ups and fedex
02:48 PM roycroft: 25cm x 25cm x 50cm, as a somewhat random but probably typical example
02:49 PM Plaid: That should totally fit in a fedex drop box
02:49 PM roycroft: the parcels will contain a lot of air
02:49 PM roycroft: i'll get that all sorted
02:49 PM Plaid: They easily fit an oversized 9x14" envelope
02:49 PM roycroft: i would prefer to have daily pickup service, eventually
02:49 PM roycroft: um, no
02:49 PM roycroft: CM
02:49 PM roycroft: not MM
02:50 PM Plaid: .... I'm bad at metric
02:50 PM roycroft: 25cm = 10 inches
02:50 PM Plaid: FREEDOM UNITS
02:50 PM roycroft: 50cm = 20 inches
02:50 PM roycroft: SENSIBLE UNItS
02:50 PM Plaid: Those still _might_ fit.
02:51 PM Plaid: Do you normally ship them ground or express?
02:51 PM roycroft: ground
02:52 PM roycroft: but i will ship something as quickly as the recipient wishes and is willing to pay for
02:54 PM Plaid: Okay, check your packaging, and make sure your plans (generally) keep it under 166 CUin per Lb
02:56 PM Plaid: So if your sample product is 10lbs, you want the box holding it to be under 1660 cu in
02:57 PM Plaid: Rounding up to the nearest whole inch
02:58 PM Loetmichel: roycroft: not exactly
02:58 PM Loetmichel: 25.4mm -> 1 inch
02:58 PM Plaid: Loetmichel: not exactly
02:58 PM Loetmichel: ./pedantic :)
02:58 PM Loetmichel: Plaid: not?
02:59 PM * JT-Shop gets his Weihenstephaner and looks into roguish[m] problem
03:01 PM Plaid: Loetmichel: I thought you were missing a decimal place :P
03:02 PM Loetmichel: i wasnt
03:02 PM Loetmichel: <- is electronican/mech. engineer. NOT bricklayer. I measure in mm, not cm
03:03 PM Loetmichel: :D
03:03 PM Plaid: I'm an american. FREEDUMB UNITS!!!!!!!!!!!!!!!11111
03:03 PM roycroft: loetmichel: unless we approach things sensibly there's no chance we'll ever actually start using SI units in this country by lay people
03:03 PM roycroft: and high precision conversions is not sensible for that purpoase
03:03 PM roycroft: purpose
03:04 PM Plaid: But you have to do shipping math in inches.... either that, or you have some wacky rounding rules
03:04 PM roycroft: sure
03:04 PM roycroft: and i do
03:04 PM roycroft: but when discussing rough sizes, i can feel free to use whatever unit system i choose
03:05 PM Plaid: UPS's rules are to take the actual package size, then round up to the closest 25.1mm :P
03:05 PM Plaid: 25.4 even
03:05 PM roycroft: ups's rules are to figure out what it should cost, then add as much more as they can get away with, and then mishandle the parcel anyway
03:06 PM roycroft: either by delaying delivery with no recourse or damaging the parcel with no recourse
03:06 PM Plaid: Yep. And my job is to basically help the accountants fight the bill on a weekly basis :P
03:07 PM pcw-home: UPS does like to tenderize packages
03:07 PM Plaid: Well, for shipping, it should be able to handle a... I think it's 4'... drop onto each corner and side
03:07 PM solarwind: pcw-home quick question: what PCIe endpoint chip are you using?
03:07 PM Loetmichel: roycroft: well, over here the UPS driver even takes the package that i lifted into his truck that made the rear axle visibly dive into the springs.
03:07 PM Loetmichel: so much for weight limits ;)
03:08 PM roycroft: it really depends on the driver
03:08 PM roycroft: when i got my jointer a couple years ago i paid for liftgate service
03:08 PM Loetmichel: (AND it got delivered. Wonder how they lifted that out of the truck in the first place :D )
03:08 PM pcw-home: <solarwind>: XIO2001
03:09 PM roycroft: ups made it a HUGE deal that the driver would pull up in front of my driveway, use the lift gate to put the machine on the street, and drive away
03:09 PM solarwind: thanks
03:09 PM roycroft: they emphasized that multiple times
03:09 PM roycroft: when the driver arrived he did that, and then helped me move it up my driveway into my shop
03:09 PM roycroft: i never told on him
03:10 PM roycroft: being nice and smiling goes a long way
03:10 PM Plaid: I think their limit is actually something like 120 or 150lbs. It just gets stupidly expensive at that level
03:10 PM roycroft: this was ups freight
03:10 PM solarwind: pcw-home out of curiosity, why not native PCIe? Why PCI at all?
03:11 PM roycroft: i had one delivery years ago where i told ups a half dozen times that i live on a dead-end street with no turn-around, and that they should send a box truck and not a semi-trailer
03:11 PM Plaid: HAHAHA
03:11 PM roycroft: they sent the semi-trailer anyway, and the driver ignored the "dead end" signs, and then got really pissed off that he had to back up three blocks to get out
03:12 PM roycroft: it's kind of hard to turn around when you're pulling a 40' trailer and the street is 33' wide with no turn-around
03:12 PM Loetmichel: roycroft: in germany we say: "Wie man in den Wald hineinruft so schallt es zurück!" (How you call into the woods it echoes back)... and yes, a smile an friendlyness goes a long way with stressed service personell
03:13 PM Loetmichel: -y+ie
03:13 PM Plaid: Only after I've left the places that had ones I could use, I'm more frequently needed a loading dock.
03:13 PM pcw-home: <solarwind>: no open PCIE implementations at the time (all proprietary glue to proprietary hardware)
03:13 PM roycroft: if i ever move to a commercial space i won't worry about a loading dock
03:13 PM roycroft: because i'll get a fork lift
03:13 PM roycroft: if there is a dock that would make life easier
03:14 PM roycroft: but a fork lift can handle anything
03:14 PM Plaid: I've writtten software for warehouses several times, but more then once I've wished I had a loading dock I can have things dropped off at.
03:15 PM Plaid: And I was in good with both of the warehouse managers
03:15 PM Plaid: Because I wrote software that fixed their problem.
03:16 PM Plaid: Either of them I could have totally asked "Umm, can I have this lathe dropped off here, and would you give me a hand loading it into my truck?"
03:25 PM solarwind: sigh
03:25 PM * travis_farmer[m] STILL waiting for UPS to show up...
03:27 PM Tom_L: dude i told you they're not done playing football!
03:27 PM Tom_L: patience...
03:29 PM * JT[m]1 uploaded an image: (348KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/VsKFzmEFmlxgpwoxgTuTOBDJ/20230106_152903.jpg >
03:30 PM Tom_L: cute
03:31 PM Tom_L: all 24 v?
03:31 PM JT-Shop: the old one was a mess
03:31 PM JT-Shop: the new is 120vac
03:31 PM JT-Shop: the old was pneumatic
03:31 PM Tom_L: it was state of the art when it was made probably
03:31 PM Plaid: I wish I had an air compressor worth a manifold like that
03:32 PM Tom_L: <-- 5hp 80 gal
03:32 PM Plaid: <-- Harbor Freight El-cheap-o pancake
03:33 PM travis_farmer[m]: <-- Makita noisy bastard
03:33 PM * JT[m]1 uploaded an image: (278KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/mYxBbFBsnhTMzkptXzncKtwQ/20230106_153251_806416334733667757.jpg >

03:33 PM Plaid: I'm debating how strong of a breeze my pancake could supply for chip clearing
03:34 PM Tom_L: JT[m]1, drier?
03:34 PM * JT-Shop goes to make some chicken crack
03:34 PM JT-Shop: yes
03:35 PM JT-Shop: use it for the blast cabinet and for powder coating
03:35 PM Plaid: Can a small-ish pancake actually supply enough for some chip clearing?
03:35 PM Tom_L: use mine to air tires nowdays :)
03:35 PM Plaid: Of AL chips
03:36 PM Tom_L: i tell you though, it had trouble keeping up with HVLP
03:36 PM Tom_L: we got another one for that eventually
03:36 PM ZincBoy[CAON][m]: Yes, but only in bursts. If you want continuous air blast you need to go bigger.
03:37 PM Tom_L: the one for HVLP did just fine
03:38 PM Tom_L: more a 'reverse vacuum'
04:21 PM travis_farmer[m]: UPS!
04:25 PM * roycroft has a big ups in his car
04:25 PM roycroft: but not the 240v one
04:25 PM roycroft: because my boss freaked out about it again
04:26 PM roycroft: this time for a different reason
04:26 PM roycroft: i told him i wanted to use a 240v ups anyway, and that it really would cost the same for the wiring
04:26 PM roycroft: and he said he has stuff that runs on 120v that he needs to put on the ups, and can't use the 240v one for that
04:26 PM roycroft: i tried to explain the concept of a transformer to him
04:27 PM roycroft: but ended up just grabbing the other 120v one and walking out the door with it
04:40 PM travis_farmer[m]: the ATC spindle has arrived! it was crated VERY well. i am impressed actually. figured it would be a carboard box... but it is a wooden box, with good re-usable hardware on it. :-)
04:42 PM roycroft: and that wood is probably some kind of southeast asian hardwood
04:42 PM roycroft: which is often suitable for making small items
04:42 PM travis_farmer[m]: and it came with a BT30 tool holder... i bought one thinking it would not be included. so now i have 2 :-)
04:43 PM travis_farmer[m]: some sort of plywood
04:43 PM * JT-Woodshop listens to Kashmir
04:44 PM XXCoder: 2 is enough to do a lot more
04:44 PM travis_farmer[m]: lead is not good for you JT ;-)
04:44 PM XXCoder: heavy metal eh
04:44 PM roycroft: led zeppelin aren't really heavy metal
04:45 PM roycroft: they're more like tempered metal
04:45 PM JT-Woodshop: lol
06:03 PM Plaid: roycroft: Call it a dual-120v UPS :P
06:04 PM Plaid: Does the UPS have 220/110 connections, or just 220?
06:04 PM Plaid: And if it's a computer, most computers can take 220 as well as 110
06:05 PM DigitalReaper: your error was trying to explain something. if you just said "it's a 120v output addon" he probably wouldn't have questioned it
06:16 PM roycroft: 240vac in and 120vac out
06:17 PM roycroft: he still doesn't understand that 30a is 30a, no matter the voltage, and that wires only (for the most part) care about the amperage
06:18 PM roycroft: if the wire is rated at 600v, it will handle 30a@1v and 30a@600v the same
06:19 PM XXCoder: thats why station to station wires is set to very high voltage
06:19 PM roycroft: that's why the power grid transmission wires are typically 50kv and up
06:19 PM roycroft: imagine how big the wire would have to be if you were transmitting 120v@30a from idaho to eugene
06:55 PM Tom_L: just use a wireless transmission
08:57 PM XXCoder: fun watching guy restore grandfather clock older than usa
09:06 PM Bleepshop: roycroft: Cross section about the same as a 55 gallon drum to amke sure you got 30A at your end. LOL
09:09 PM XXCoder: yeah lets do that in middle of copper peak
09:10 PM Bleepshop: pcw-home: Hope I didn't blow my $18.25 after tax because I ordered one of these to cure my network issues. https://www.amazon.com/gp/product/B084P2K7TV
10:36 PM snakedGT is now known as snaked
11:20 PM XXCoder: lol https://youtu.be/u2mYjueIcAE
11:20 PM XXCoder: might be useful for people with large land lots
11:22 PM XXCoder: if I recall its another 2k usd to ship it
