08:08 AM travis_farmer[m4: well, i picked up the pair of oil furnaces last night. my father and i will go over them after he gets home from work, to make sure they survived the trip home and the heat-exchangers didn't rattle to a pile of rust. they were purchased from a dark garage, with a flashlight. they ran both of them for me, and they ran good, nice steady burn, and i didn't notice any oil fumes inside the garage from the air that blew out of them.
08:37 AM travis_farmer[m4: i am currently the only entry in the log... i am all alone here...
08:41 AM sensille: your log is too short
08:42 AM travis_farmer[m4: not my log, this log: http://tom-itx.no-ip.biz:81/~tom-itx/irc/logs/%23linuxcnc/2023-07-21.html now your in it too
08:47 AM randy: the bot was not online.
08:48 AM randy: 230721135336 -!- c-log [~c-log@ip24-255-195-170.ks.ks.cox.net] has joined #linuxcnc
08:48 AM randy: (CEST)
08:59 AM bjorkintosh: JT-Cave, close? https://imgur.com/a/bzncADm
08:59 AM bjorkintosh: or Nyet?!
09:01 AM JT-Shop__: I don't see the ladder
09:11 AM -!- #linuxcnc mode set to +v by ChanServ
09:17 AM bjorkintosh: alright.
09:18 AM bjorkintosh: JT-Shop, same link.
09:18 AM bjorkintosh: https://imgur.com/a/bzncADm
09:19 AM bjorkintosh: Not sure it's correct but it's what I think the puzzle is.
09:57 AM roycroft: the sky is slightly orange again this morning, but it doesn't smell like smoke (at the moment)
09:58 AM roycroft: and i've confirmed that the smoke is from the flat fire - there must have been some really high speed winds to blow it up here that fast
10:06 AM bjorkintosh: what's a flat fire?
10:06 AM bjorkintosh: type of material?
10:08 AM bjorkintosh: I've been watching this channel lately: https://www.youtube.com/@USCSB so fires have been of recent interest.
10:10 AM roycroft: our fires are named, often for a geographic feature near them
10:10 AM roycroft: the flat fire is in southwestern oregon, and i don't know how it got its name
10:13 AM Unterhausen: I'm amused that someone built a 3d printer big enough to print a life-sized version of himself and the result doesn't really look like him
10:13 AM bjorkintosh: who?
10:18 AM JT-Shop: bjorkintosh, close on the output but it's copy fill and look at the system contacts
10:20 AM bjorkintosh: JT-Shop, yeah I'm looking at videos and reading docs to better understand.
10:20 AM bjorkintosh: that's what I came up with based on what I currently know.
10:21 AM bjorkintosh: oh, btw. thanks a lot for suggesting the input sim. it's made things a little less tedious.
10:21 AM bjorkintosh: I didn't even know such a thing existed.
10:22 AM Rab: <CaptHindsight[m]> https://imgur.com/gallery/Hz81zwg
10:22 AM Rab: Related media: https://imgur.com/15pWY3X
10:22 AM Rab: This is better than the last 20 Star Wars.
10:23 AM JT-Shop: actually it's system control relays
10:24 AM bjorkintosh: that's what I'm calling the input sim?
10:24 AM JT-Shop: no, Program > Address Picker > SC
10:25 AM JT-Shop: look at the first 9 system control relays
10:25 AM JT-Shop: https://www.automationdirect.com/microsites/clickplcs/click-help/Content/109.htm
10:26 AM JT-Shop: they are very useful
10:27 AM bjorkintosh: oh I see.
10:28 AM JT-Shop: it's best if you try first then I give you a hint
10:34 AM JT-Shop: bjorkintosh, to remind you of the puzzle set DS1-10 to 0 once when the program starts
10:35 AM JT-Shop: because they are retentive you want to start up in a known state
10:43 AM bjorkintosh: Okay. I'll try it again.
11:24 AM bjorkintosh: JT-Shop, I think I got it: https://imgur.com/a/6IQwx1v
11:28 AM Tom_L: which plc did you get?
11:28 AM JT-Shop: bjorkintosh, perfect
11:28 AM JT-Shop: bbib with the next lesson
11:33 AM bjorkintosh: Tom_L, I got a click plus: https://www.automationdirect.com/adc/shopping/catalog/programmable_controllers/click_plus_plcs_(stackable_micro_modular)/cpus/c2-03cpu
11:34 AM bjorkintosh: it has bluetooth, wifi, ethernet and so on. it's not their most basic model.
11:38 AM bjorkintosh: CaptHindsight[m], just now checked out plcfiddle. thanks for that.
12:23 PM roycroft: my boss finally agreed to my vacation request next month
12:24 PM roycroft: it's a good thing he did, because i already have camping reservations and it's doubtful i'd find anything decent at this point if i were to try to change them
12:26 PM JT-Shop: bjorkintosh, go to Setup > System Configuration add your power supply and any I/O cards and take a screen shot of that
12:34 PM CaptHindsight[m]: ladder logic should be written with noseplugs
12:37 PM bjorkintosh: JT-Shop, https://imgur.com/a/uOIC7xV
12:40 PM JT-Shop: This post may contain erotic or adult imagery.
12:40 PM JT-Shop: By continuing, you acknowledge that you are 18+ years of age.
12:40 PM roycroft: are you goin to the chicken pr0n site again?
12:40 PM JT-Shop: interesting I didn' know the plus had two slots
12:41 PM roycroft: fedex just failed
12:41 PM roycroft: they try to do stealth deliveries these days
12:41 PM JT-Shop: but anyway you can see important info about your power consumption and the I/O addresses for each card
12:41 PM roycroft: but the driver did not set the boxes down gently enough, and i heard him
12:44 PM mrec: getting quotations for pinion gears is interesting, small pinions 100-1000 pieces where the material costs like 0.20$ they want to sell it for 5-10$; for that amount I keep doing it myself;
12:44 PM bjorkintosh: JT-Shop, yeah. that's how I realized the usefulness of the input simulator.
12:44 PM JT-Shop: https://paste.debian.net/1286556/
12:44 PM bjorkintosh: so my plus has one slot. the slightly more expensive one has two.
12:45 PM bjorkintosh: okay.
12:45 PM JT-Shop: ok, I've never used a plus I just use the basic and standard ones
12:45 PM JT-Shop: but it's all the same with the ladder
12:46 PM JT-Shop: and DS1 is Step
12:50 PM CaptHindsight[m]: mrec: I have seen similar, shops only interested in high profit margin jobs, I don't blame them
12:51 PM CaptHindsight[m]: not sure who has low prices for medium size orders
12:52 PM CaptHindsight[m]: the other thing I'm seeing is large OEM's complain about how they can't get good yields out of the job shops and assemblers they contract out to...
12:53 PM CaptHindsight[m]: they don't seem to understand that you often get what you pay for
12:57 PM roycroft: well it stands to reason that if you're unwilling to pay for something, the supplier does not have profit as a motive to produce the goods, leaving the reputation as a manufacturer of high quality goods the primary motivation for the supplier, so you should expect top quality goods for nothing, and mediocre quality goods if you are willing to pay top dollar
12:57 PM bjorkintosh: JT-Shop, I don't know why imgur rates it as mature but ... here it is: https://imgur.com/a/6t68vtn
12:58 PM mrec: CaptHindsight[m]: but pinions... if someone has a good lathe it's a job of seconds
12:58 PM mrec: it takes me 1 minute to hob a gear at 300rpm, I need to keep modifying my machine a little bit more to increase the speed
01:01 PM mrec: I'm still using it via parallel port, the mesa card is still lying around since I need a breakout board for more IOs
01:01 PM mrec: I did some test setup with the mesa where it performed well via ethernet
01:02 PM mrec: another thing they said they have issues with 0.8mm thin gears, I even cut those things from sheet metal and it was absolutely no problem to manufacture them
01:03 PM JT-Shop: bjorkintosh, also DS1 is Step
01:05 PM bjorkintosh: alright. https://imgur.com/a/Hmc0Goo
01:09 PM JT-Shop: perfect
01:09 PM JT-Shop: https://paste.debian.net/1286562/
01:09 PM JT-Shop: now write the program
01:10 PM CaptHindsight[m]: mrec: I asked for some quotes recently. It was like they all wanted to cover their monthly overhead on the one job.
01:11 PM CaptHindsight[m]: even had one come back and say "we don't work in metric"
01:12 PM CaptHindsight[m]: 99.9% of the machine shops only use machines, they don't and can't do any mods
01:13 PM CaptHindsight[m]: if a PLC goes out and the machine is out of warranty they will hope to be able to copy the program from the dead one to a new one, they can't program anything on their own
01:15 PM mrec: my plan is to finalize my pick and place machine, afterwards make an extension board for my mesa card and update the machinery. I just need to update the optical recognition code and I'm done.
01:15 PM mrec: Today I reworked the SMD feeder firmware, my first pinions weren't that accurate so I compensate that issue in software, I know I can do it better next time
01:16 PM mrec: the gears are transferring the motor power to the sprocket which advances the SMD tape, so any inaccuracy will result in advancing a wrong distance of the tape
01:16 PM mrec: still for the first time it's all good
01:17 PM CaptHindsight[m]: are you using a closed loop system or step and pray?
01:17 PM mrec: I'm just using steppers, I had no repeatability issues with the feeders so far
01:18 PM CaptHindsight[m]: closed loop for when you absolutely, positively want to be where you need to be, like fedex
01:25 PM Rab: CaptHindsight[m], ever tried this? https://github.com/multigcs/viaconstructor
01:26 PM CaptHindsight[m]: Rab: this is the first I've seen that one
01:26 PM Rab: It seems to do what it claims, but I haven't tried any gcode.
01:27 PM Rab: Hmm, this is their other big project: https://github.com/multigcs/LinuxCNC-RIO
01:29 PM CaptHindsight[m]: saw that before: RealtimeIO for LinuxCNC based on an FPGA, no Soft-Core, logic only
01:30 PM CaptHindsight[m]: no Ethernet either since no cpu
01:35 PM bjorkintosh: JT-Shop, okay. I need to figure out how to do conditionals. I thought it was one of the instruction options. gotta think for a sec.
01:42 PM CaptHindsight[m]: IF, Else
01:51 PM JT-Shop: that's python...
01:52 PM JT-Shop: if fi
01:52 PM JT-Shop: if then fi
01:52 PM JT-Shop: lol
01:57 PM JT-Shop: bjorkintosh, think about the latch in circuit you made... hint hint
02:21 PM bjorkintosh: alright. it doesn't need a comparison for everything. lemme think.
02:25 PM pcw---home: CaptHindsight There are FPGA hardware UDP and even TCP stacks (but quite wasteful with hardware unless you need extreme througput)
02:27 PM solarwind_: ooooh CaptHindsight[m] pcw---home this sounds like my kind of discussion
02:27 PM solarwind_ is now known as solarwind
02:28 PM solarwind: CaptHindsight[m] I'm mostly finished my FPGA-based EtherCAT core
02:29 PM solarwind: It's based on a Zynq, connected via PCIe and does 100% of the EtherCAT protocol on the card
02:29 PM solarwind: full bypass of the network stack. LinuxCNC just tells the card what it wants to do and the card handles the rest
02:30 PM CaptHindsight[m]: solarwind: I have some zedboards to test on
02:30 PM solarwind: I'm _very_ impressed with my servo update rates. I'm getting 8kHz update rates in CiA Cyclic Synchronous Torque profile easily. Haven't tested 16kHz yet
02:31 PM solarwind: but I want to open source these designs soon
02:31 PM solarwind: The dev board I'm using is from a guy on aliexpress who makes his own, I linked them to you a few months ago
02:31 PM CaptHindsight[m]: which is the lowest cost zynq part currently?
02:31 PM CaptHindsight[m]: they used to be ~$100ea
02:32 PM solarwind: The thing is, you need the model which has at least 1 transceiver for PCIe
02:32 PM solarwind: well you don't _need_, but I like to avoid a PCI bridge chip and all that
02:33 PM CaptHindsight[m]: https://www.mouser.com/ProductDetail/Xilinx/XC7Z007S-1CLG225C?qs=rrS6PyfT74fgOhuz6L0Z5g%3D%3D
02:33 PM solarwind: https://docs.xilinx.com/v/u/en-US/zynq-7000-product-selection-guide
02:34 PM solarwind: Either the XC7Z7012S or the XC7Z015
02:34 PM zyp: jlcpcb have 7015 starting at $32 in singles
02:35 PM zyp: https://jlcpcb.com/partdetail/Xilinx-XC7Z0152CLG485I/C1522056
02:35 PM solarwind: The PCIe part is super simple without having to use a PCI bridge and then another to bridge back to PCIe
02:36 PM CaptHindsight[m]: zyp: oh, that's not bad
02:36 PM solarwind: I'm just using the Xilinx PCIe IP core and it works fine, but I haven't thought about the implications of open sourcing with that. pcw---home would know a lot more about it
02:36 PM solarwind: I have so many random little projects like this going on in parallel.
02:37 PM solarwind: and with ADD (like legitimate diagnosed ADD), you can understand why my workshop is a mess lol
02:37 PM solarwind: I need you to keep me on track <3
02:37 PM CaptHindsight[m]: zyp: same device at Mouser is >$200
02:38 PM solarwind: ADD is such a curse. Adderall helps a lot but it only goes so far
02:38 PM pcw---home: Not sure about the PCIE core licensing for Zync, I don't think anything from the core generator is open source
02:39 PM zyp: if you don't need the cpu side of the zynq, most artix 7 parts also seems to have transceivers, including this $18 part: https://jlcpcb.com/partdetail/Xilinx-XC7A35T2FGG484C/C1521748
02:40 PM zyp: litepcie is open source and builds on top of some of the xilinx IP
02:41 PM zyp: I believe the opensourced repo mainly contains the xml that tells the IP generator what to make, not the output of it
02:46 PM zyp: ah, that has changed since last I looked, now it's configuring the IP generator directly through tcl rather than feeding it a premade xml: https://github.com/enjoy-digital/litepcie/commit/9e4a935
02:47 PM CaptHindsight[m]: solarwind: could be worse, could be ADD + anxiety disorder
02:48 PM CaptHindsight[m]: I'm scared. Of what? I forget.
02:54 PM bjorkintosh: JT-Shop, https://imgur.com/a/MoTcxSc
03:06 PM solarwind: CaptHindsight[m] I have that too
03:06 PM solarwind: zyp yup I have those cards too
03:10 PM solarwind: There are open PCIe implementations out there, just have to find them
03:10 PM solarwind: the protocol is not complicated
03:10 PM solarwind: I just don't have the time to implement from scratch right now
03:12 PM solarwind: pcw---home FYI this exists: https://www.asix.com.tw/en/product/Interface/PCIe_Bridge/AX99100
03:12 PM solarwind: it's a very cheap PCIe to various bus interface including a 8/16 bit local bus
03:13 PM solarwind: It's an easy way to avoid having to do PCIe <-> 32 bit PCI when you don't need 32 bit bandwidth but still need the latency advantages of PCIe. Also supports SPI, I2C, UART and all that
03:16 PM solarwind: I've read the datasheet, it's _very_ flexible. It's very commonly used in those $10 PCIe serial port/parallel port cards you can get anywhere.
03:32 PM JT-Shop: bjorkintosh, excellent I like the reuse of the first rung to reset the step count
03:32 PM JT-Shop: now add a rung that when you press the auto button it latches in Auto Mode C1 and use Auto Mode instead of Auto and break the latch with the stop button
03:34 PM bjorkintosh: hmm. okay. let me think.
03:40 PM roycroft: sw is kicking my butt today, perhaps kind of like it was doing to unterhausen the other day
03:41 PM roycroft: i derived a part from a library (a structural member), and saved it as a certain length
03:41 PM roycroft: saving it to a local directory, not back to the library directory, so it's editable and allegedly unlinked from the library version
03:42 PM roycroft: i then adjusted the length of the part and saved it with a new name, retaining the original
03:42 PM roycroft: i could insert both into my assembly just fine, and saved the assembly
03:42 PM roycroft: but if i close the assembly and reopen it, it opens with a bunch of mate errors, and the copy of the drived part reverted to the original length from when i derived it
03:43 PM roycroft: if i open the part stand alone, however, it has the correct length
03:43 PM roguish[m]: sounds like it's not totally unlinked...
03:43 PM roycroft: yes
03:43 PM roycroft: but it should be, because i told sw to unlink it
03:43 PM roycroft: and it seems to be, but also seems not to be
03:44 PM roguish[m]: under File, there's a way to check references. in it you should be able to unlink all
03:44 PM roycroft: probably the easiest thing to do would be to go back to the library and derive a new part with the second length
03:44 PM roycroft: i'll check that first to be sure, but i think it's unlinked, mostly
03:48 PM JT-Shop: yup been there done that with file paths and same name parts
03:52 PM roycroft: i'm using unique names for the parts
03:53 PM roycroft: c3x4.1x120.sldpart is the first one i derived, and it's 120 inches long
03:53 PM roycroft: i saved it as c3x4.1x53.75.sldprt when i shortened it
03:53 PM roguish[m]: well, up to 99.3 right now...
03:54 PM roycroft: but the shortened part is still based on the original x120 configuration, and i can't find a way to change that
03:54 PM roycroft: so i'll just derive a new part - that will only take a few seconds, and will get me down the road
03:54 PM roycroft: i do want to figure this out at some point though
03:55 PM roguish[m]: is the length dimension tied to something?
03:55 PM JT-Shop: did you save as the new part?
03:55 PM roycroft: yes
03:56 PM roycroft: so when one derives a part from the library, it gets saved back to the library
03:56 PM roycroft: and it is read-only
03:56 PM roycroft: but i can then open that derived part, and save it as a new part in a local directory
03:56 PM roycroft: and that newly-saved part is editable
03:56 PM JT-Shop: hmm, can't say I've ever used a library part...
03:56 PM roycroft: i use them all the time
03:57 PM roycroft: fasteners and structural members especially
03:57 PM JT-Shop: but does it still have ties to the original part somehow?
03:57 PM roycroft: it does, as i've discovered
03:57 PM JT-Shop: I use mcmaster carr for that
03:57 PM roycroft: i use mcmaster when the sw library doesn't have what i need
03:57 PM roycroft: but using the library is a bit faster
03:58 PM roycroft: i'll just derive a new part for now, and finish up this project
03:58 PM roycroft: i found 50' of 1" square tubing on my metal stock rack, and i was already thinking about using 1" square tubing for the sides of the trailer
03:58 PM roguish[m]: I created an 80/20 library for the structural design
03:59 PM roycroft: i downloaded the complete 80/20 sw library
03:59 PM roycroft: it's really nice - i can just go grab what i need
03:59 PM roguish[m]: yup
03:59 PM roycroft: i look in the printed catalog first, find what i need, and then go find it in the library
03:59 PM roycroft: and thank you, 80/20, for still printing catalogs
04:00 PM JT-Shop: I can't even find any library parts...
04:01 PM roguish[m]: I keep a directory full of pdf catalogs.... dozens in there now
04:01 PM roguish[m]: with a shortcut on the desktop\
04:06 PM roycroft: you have to install the toolbox
04:11 PM JT-Shop: ok
04:12 PM JT-Shop: I need to uninstall 2015 and install 2014 so onecnc can import a sw file
04:20 PM XXCoder: crazy https://youtu.be/o8VBw_Q0OWE
04:20 PM XXCoder: guy makes cnc to just make box cutouts
04:28 PM JT-Shop: interesting sorter
04:28 PM XXCoder: yeah
04:31 PM JT-Shop: need to tape his hands down lol
04:31 PM roycroft: most folks use a counter scale for that
04:32 PM roycroft: weigh 10 fasteners, set the quantity you want in a group, and pile the fastenrs on the scale until it tells you to stop
04:32 PM JT-Shop: counter scale won't work for sorting out and presenting parts for assembly
04:33 PM roycroft: yeah, it might not be good for that
04:34 PM roycroft: but still, my impression of that video is that it's a solution looking for a problem, because the guy likes to "cnc" everything
04:34 PM XXCoder: well counter thing isnt really the reason I linked to video :)
04:41 PM JT-Shop: the sorter is rejecting all fasteners that are not in the correct orientation...
04:41 PM bjorkintosh: hmm. I think my initial ladder logic is buggy.
04:41 PM bjorkintosh: thinking through it to make sure.
04:43 PM roycroft: you're thinking maybe it's your brain that is buggy? :)
04:46 PM bjorkintosh: without a doubt.
04:46 PM roycroft: join the club
04:47 PM XXCoder: fun
04:47 PM JT-Shop: bjorkintosh, did you run it?
04:47 PM JT-Shop: looked correct to me...
04:48 PM JT-Shop: bjorkintosh, I will be gone Saturday and Sunday
04:49 PM XXCoder: jt what did you think of cnc part?
04:49 PM XXCoder: was curious on your viewpoint on cnc machine lol
04:49 PM JT-Shop: other than the open gears full of chips it looked ok
04:49 PM XXCoder: yeah was thinking similiar. wondered how to protect those
04:50 PM JT-Shop: I would have added some pneumatic clamps to hold the part to speed up cycle time
04:50 PM XXCoder: interesting. though if smaller batches may not be worth it. how would it cost?
04:51 PM JT-Shop: not much at all for a couple of pneumatic cylinders and a few bits and a couple of solenoids
04:53 PM roycroft: vacuum clamps would be even less expensive to add
04:53 PM roycroft: assuming one already has a source of vacuum
05:01 PM roycroft: kevin mitnick has left the building
05:01 PM bjorkintosh: JT-Shop, I did run it.
05:01 PM bjorkintosh: the value doesn't change to 30.
05:02 PM bjorkintosh: it instead resets to 0
05:02 PM bjorkintosh: so i'm able to do 0, 10, 20. and then when I flip the switch for 30, it just goes back to 0
05:03 PM JT-Shop: ok, let me look again
05:04 PM JT-Shop: ah yep it happens in one scan so you will never see it, if auto is on it will go to 10
05:04 PM bjorkintosh: how can you tell?
05:07 PM JT-Shop: as soon as ds1 == 30 it will set ds1 to either 0 or 10 depending on the state of Auto
05:07 PM JT-Shop: did you get the auto button to latch in auto mode?
05:08 PM bjorkintosh: not yet.
05:08 PM JT-Shop: so if you want to "see" ds1 at 30 you would need a time delay at 30
05:08 PM bjorkintosh: I see. let me take another look.
05:08 PM JT-Shop: you're a programmer now... just need some more practice
05:09 PM JT-Shop: you have the fundamentals of writing a long program that does a sequence of events now
05:09 PM JT-Shop: a lot can't do that... and I've seen some really bad code over the years
05:09 PM bjorkintosh: I understand. the program is behaving correctly. I see now why it flips to 10 or 0.
05:10 PM bjorkintosh: the screen did not display that portion because I had it zoomed in so I forgot about that portion.
05:11 PM bjorkintosh: I think what I'm currently missing the requisite jargon. it took me a minute to decipher the puzzle before the last one.
05:11 PM bjorkintosh: but once I understood the requirements, it made sense.
05:14 PM bjorkintosh: thanks for the vote of confidence, JT-Shop. I'm going to attempt the last puzzle now.
05:14 PM JT-Shop: btw it's not the "last" puzzle :)
05:15 PM Tom_L: heh
05:17 PM XXCoder: yay inheirance machining time
05:21 PM bjorkintosh: hahaha
05:22 PM bjorkintosh: the most recent puzzle.
05:23 PM JT-Shop: :)
05:28 PM JT-Cave: gotta pull out at 7am tomorrow
05:29 PM JT-Cave: Tom_L, I finally ordered that usb c sd card reader with something else so I did't have to pay 100% shipping
05:40 PM Tom_L: been a while.. i forgot about that
05:42 PM Tom_L: where's the road trip this time?
05:42 PM JT-Cave: lunch in Hermann then on to Williamsville and overnight in Fulton
05:43 PM JT-Cave: Fulton has a couple of museums one is a Churchill museum
05:43 PM JT-Cave: I forget what the other one is
05:43 PM JT-Cave: going to a couple of places in williamsville
05:44 PM Tom_L: fun
05:45 PM JT-Cave: We will leave from Rhodes 101 Convenience Store at the corner of Highway 61 and 51 in Perryville at 8 AM. We will drive the scenic route through Ironton, Steelville, Cuba, etc. With several bathroom stops along the way. We will eat at Hermann, Mo. After lunch we will drive to Williamsburg, MO. There we will have ice cream at Marlene's Restaurant, tour Crane's Museum and Crane's Old Time store.

05:54 PM Tom_L: JT-Cave, is crane's a community museum?
05:55 PM Tom_L: he leasses sq/ft i see
05:55 PM solarwind: gigantic spindles, so insanely rigid, zero chatter
05:56 PM Tom_L: solarwind, http://tom-itx.no-ip.biz:81/~webpage/cnc/cincinnati/Cincinnati_5.jpg
05:56 PM solarwind: Whish I can own a cincinnati no. 5 someday
05:57 PM Tom_L: 3 heads
05:57 PM Tom_L: 2 gantries per bed
05:57 PM solarwind: well that's not the Cincinnati no. 5 I was thinking of
05:58 PM Tom_L: they are beasts
05:58 PM solarwind: https://i.ytimg.com/vi/-Vjo6OiKkeY/hqdefault.jpg that's what I was thinking of
05:58 PM Tom_L: i figured roughly as much
05:59 PM Tom_L: still pretty heavy iron
05:59 PM solarwind: It's about 10 tons
06:00 PM Tom_L: better brace the floor
06:01 PM solarwind: Any industrial concrete will do
06:01 PM solarwind: my floor holds the 10 ton forklift just fine and the pressure on the wheels is probably a lot higher than a large surface area machine base like that
06:02 PM solarwind: I'm more amazed with forklift cushion tires themselves. Fully loaded, it's about 15 tons on the front tires assuming perfect balance
06:03 PM solarwind: The axles and everything designed to roll like that all day every day
06:04 PM solarwind: I don't know what these tires are made of, but they're certainly a lot tougher than human skin
06:05 PM solarwind: mildly scraping a brick wall is enough to cause bleeding
06:24 PM bjorkintosh: JT-Shop, familial obligations have interfered with my solution. I'll have it done by monday.
06:24 PM bjorkintosh: thanks for the puzzles and have a good weekend.
07:29 PM JT-Cave: will do
07:29 PM JT-Cave: you too
07:30 PM JT-Cave: Tom_L, I'm not sure
