12:30 AM mrec: https://i.snipboard.io/B0UPGO.jpg
12:38 AM mrec: the L bracket was never meant to have an installation like that
12:38 AM mrec: pcw-home: what do you mean with spindle orientation?
12:38 AM mrec: retval = hal_pin_bit_newf(HAL_OUT, &(addr->pos_mode),
12:38 AM mrec: comp_id, "stepgen.%d.pos_mode", num);
12:38 AM mrec: if (retval != 0) { return retval; }
12:38 AM mrec: I think about this one
12:38 AM mrec: static int export_stepgen(int num, stepgen_t * addr, int step_type, int pos_mode)
12:38 AM mrec: and wait for the disaster to happen :-)
12:40 AM mrec: but I still need position control too
12:40 AM mrec: I'm going to cut gears
12:40 AM mrec: and it's just the regular A axis (configuration) at the moment
12:42 AM mrec: putting an fpga in between for switching between modes would certainly also be an option
12:42 AM mrec: so linuxcnc could still think it's in position mode while another option kicks in and uses the velocity
12:43 AM jpa-: though i wonder why not just run it in position loop mode, you can still set the velocity by just setting feed
12:43 AM mrec: I will try that it's just the first setup here
12:43 AM mrec: that should be fine too
01:29 AM CaptHindsight[m]: mrec: https://forum.linuxcnc.org/38-general-linuxcnc-questions/45795-spindle-orientation
01:31 AM CaptHindsight[m]: djsftree#5725: https://liliputing.com/rock5-single-board-computer-with-rk3588-coming-soon-for-129-and-up-or-45-off-for-pre-orders/
01:31 AM CaptHindsight[m]: ROCK5 with 4GB RAM for $129
01:31 AM CaptHindsight[m]: ROCK5 with 8GB RAM for $149
01:31 AM CaptHindsight[m]: ROCK5 with 16GB RAM for $189
01:32 AM XXCoder: quite a bit expensive, but better than scalp rpi4 prices
01:32 AM CaptHindsight[m]: djsftree#5725: https://liliputing.com/banana-pis-latest-compute-module-features-rk3588-chip-and-up-to-8gb-ram/
01:32 AM CaptHindsight[m]: https://www.geeky-gadgets.com/banana-pi-bpi-w3-22-07-2022/
01:33 AM CaptHindsight[m]: XXCoder: much more powerful than the RPi4
01:33 AM XXCoder: interesting
01:33 AM CaptHindsight[m]: if we can use all the integrated microncontroller then it doesn't need any extra FPGA's for stepping or encoders
01:34 AM CaptHindsight[m]: https://liliputing.com/rk3588-is-rockchips-highest-performance-processor-to-date-likely-coming-in-2022/
01:35 AM CaptHindsight[m]: https://www.cnx-software.com/2021/12/16/rockchip-rk3588-benchmarks-show-up-on-geekbench/
01:38 AM CaptHindsight[m]: XXCoder: ROCK5 with 4GB RAM for $129 would just need a power supply and some IO protection
01:41 AM CaptHindsight[m]: and a SATA drive for $24 250GB
01:42 AM XXCoder: ocerall not too expensive. I guess i'd ghave to install and setup linuxcnc myself but shouldnt be too big
01:42 AM XXCoder: i have zero budget for bext forseenable months so yeah not much lol (even if has budget, need room for it)
01:46 AM CaptHindsight[m]: https://www.amazon.com/Controller-Ethernet-Control-Stepper-Motor%EF%BC%884/dp/B07YSTYFS4 ~$100
01:46 AM CaptHindsight[m]: but needs a Rpi or similar for the GUI and servo thread RT
01:46 AM XXCoder: rock5 with that thing?
01:47 AM CaptHindsight[m]: rock5 won't need it
01:48 AM CaptHindsight[m]: NVEM CNC Controller needs a PC or rpi as the GUI and servo thread RT
01:48 AM XXCoder: how the heck did moth enter my room
01:48 AM CaptHindsight[m]: rock5 would just need some IO protection
01:48 AM XXCoder: ok
01:48 AM XXCoder: woulnt it still need MESA
01:49 AM CaptHindsight[m]: NVEM CNC Controller has an stm32 micro
01:49 AM CaptHindsight[m]: https://forum.linuxcnc.org/media/kunena/attachments/24854/slide5.png
01:49 AM XXCoder: *for rock5
01:50 AM CaptHindsight[m]: when stm32's were available that board might be $30 in parts
01:57 AM CaptHindsight[m]: 64F out, this should be nice
02:14 AM Connor1 is now known as Connor
02:49 AM mrec: actually there should be an option to switch the step_type, I cannot just use position control when eg. turning the plastic stick smaller on the mill
02:50 AM mrec: I'm looking into that, alternatively I can still install a pulse generator in the controller box, I should get a few anyway.
03:04 AM mrec: how about creating another stepgen unit and multiplexing the output to the output pin?
03:04 AM mrec: the question would be is there a module for multiplexing step signals?
03:09 AM jpa-: if you are using software stepgen, they are just binary signals
03:17 AM CaptHindsight[m]: mrec: you can make a HAL module for just about any function
03:18 AM CaptHindsight[m]: I was working on openCV video filters as Hal modules
03:48 AM mrec: it's doing something now nice
04:00 AM JT-Cave: morning
04:34 AM Tom_itx: morning
05:12 AM mrec: mux-gen.NN.sel-bitMMM bit in (M=0..N)
05:12 AM mrec: I don't quite understand this
05:12 AM mrec: what is MMM supposed to be? I create 2 channels and I have a bit-00 pin
05:13 AM mrec: net spindle-1-enable <= spindle.1.on => mux-gen.00.sel-bit-00 stepgen.6.enable
05:13 AM mrec: this seems to work so M3 enables the spindle and the stepper is turning
05:14 AM rmu: MMM is placeholder for bit number
05:15 AM mrec: I have a 2 channel generic mux how can I enable the second channel?
05:16 AM mrec: MMM doesn't make sense at all to me
05:16 AM mrec: I saw someone created 5 channels, and he had a 00 and 01 channel there
05:16 AM mrec: 00 / 01 enable channel
05:16 AM mrec: since they can only take true or false how should this map to a selection
05:17 AM jpa-: mrec: sel-bit vs. sel-int are alternative ways to select channel; e.g. sel-bit00 = 0, self-bit01 = 1 is same as sel-int=2
05:18 AM jpa-: it is so that you can multiplex more than 2 inputs with binary selection signals
05:29 AM mrec: okay got it
05:34 AM mrec: seems like mux_generic is not for me
05:35 AM mrec: every rising signal seems to toggle the output?
05:35 AM mrec: so practically the output will be half the bandwidth of the input
05:36 AM mrec: I'm more looking for a switch not for that
05:42 AM mrec: other than that it would work, as soon as I issue M5 $1 the stepper would be in spindle mode
05:42 AM mrec: M3 $1 -> spindle mode (not m5)
05:42 AM mrec: M5 $1 -> position mode
05:43 AM rmu: mrec: I don't think it toggles the output, the code doesn't look like that.
05:45 AM mrec: I did not have a look at the code yet, the motor runs slower when using mux_generic
05:46 AM mrec: wait I added it to the base-thread now it's smooth and just the same
05:48 AM mrec: very smooth now
07:15 AM Tom_itx is now known as Tom_L
08:22 AM zincboy[m]: Looks like the Discord bridge has gone down.
08:30 AM pcw-home: mrec: a common way stepgen mode switching in done is this: The stepgen is always run in velocity mode with position mode done with a hal PID loop. A mux component changes the stepgen velocity command source from PID (position mode)to say spindle speed (velocity mode)
08:32 AM zincboy[m]: I am running into issues with extended gcode remapping. The docs list "abcdefghijkmpqrstuvwxyz" as valid words that can be used for remap. GMST can't be used as they will be parsed as those command words. This makes sense as they are allowed to be on the same line. ABCUVW can't be used unless those axis are enabled. This leaves DEFIJKPQR as the usable
08:32 AM zincboy[m]: remap words.
08:33 AM zincboy[m]: XYZ are also possible but it preferred not to use them to avoid confusion.
08:36 AM zincboy[m]: It seems you are limited to 9 usable parameters for custom gcode. This is a bit limiting with complex functions that take many parameters.
08:37 AM zincboy[m]: Anyone know if there is a way to enable the ABCUVW words without having to enable those axis? When I try them I get a "Bad character 'a' used" error.
08:45 AM perry_j1987: can you add additinal function to decimal numbers
08:46 AM perry_j1987: like F0.1 = this and F0.2 = that
08:53 AM jpa-: zincboy[m]: you could consider making some options modal settings instead, if it makes sense
08:55 AM zincboy[m]: 14 of the 16 parameters I would like to use are floating point values so I can't do the F0.1 trick. Good thought though.
08:57 AM zincboy[m]: I think I will split the call into two. A optional pre-call to set global variables with the less used override values. And the main call with the typical values.
08:57 AM zincboy[m]: Would be something like:
08:57 AM zincboy[m]: G65.1 XYZDEFIJKPQR
08:58 AM zincboy[m]: G65 XYZDEFIJKPQR
08:59 AM zincboy[m]: Where the G65.1 is the optional call. Any value set in the G65.1 would get re-set at the end of the G65 call as it does not make sense to have these modal.
09:02 AM jpa-: O subroutine calls also can have more parameters, up to 30
09:05 AM zincboy[m]: Yes O subroutines can but using them with that many parameters is an exercise in frustration. The positional call structure makes optional parameters impossible so you have to have the massive call string for even one that would only need 1 value.
09:06 AM zincboy[m]: I am using o calls internally but having them user exposed would make things very hard to use.
09:50 AM JT-Shop: you might look at global named parameters
12:06 PM zincboy[m]: Thinking of adding this text to the remap documentation:
12:06 PM zincboy[m]: Axis words may also only be used if the axis is enabled. If only XYZ... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/0baf3bb1b2c370101e9e1edf76869e13449536c5)
12:06 PM zincboy[m]: Does that make sense?
12:10 PM jpa-: makes sense to me
12:12 PM zincboy[m]: Thanks. I will hold off on submitting a pull request until I am done just in case I find other issues.
01:11 PM perry_j1987: what possesses someone (my past self) to put bad drill bits back into the case lol
01:13 PM Tom_L: you collect broken endmills too?
01:13 PM perry_j1987: thats totally different
01:14 PM perry_j1987: i could maybe regrind them as some other tool :P
01:20 PM roycroft: broken endmills can be very useful reground as somthing else
01:20 PM roycroft: drills just need to be sharpened
01:20 PM roycroft: and when they get too short, they become stubby drills
01:20 PM roycroft: and when stubby drills get too short, the shanks get cut off and used as spacers/pins
01:21 PM perry_j1987: depends if the drill bits were originally made out of pot metal or not too though
01:23 PM perry_j1987: tomorrow my new vfd arives
01:23 PM perry_j1987: looking forward to getting this lathe back up
01:24 PM djsftree[m]: greetings
01:26 PM roycroft: you said "drill bits", not "twisted pieces of metal that resemble drills", so i assumed you were not talking about pot metal ones
01:29 PM perry_j1987: lol
01:29 PM perry_j1987: ya well you know marketing guys
01:29 PM perry_j1987: they will still call it a drill bit heh
01:30 PM zincboy[m]: roycroft: you mean the ones that untwist themselves as soon as they hit anything harder than butter? :)
01:30 PM perry_j1987: lol
01:57 PM roycroft: yeah, those
02:01 PM djsftree[m]: Hell all. I'm am looking for help with genserkins and a robot (meca500). I am really struggling with setting the DH. I would appreciate some help. Financial reward waiting!
02:02 PM * roycroft will make his usual suggestion to post the request to the forum, as it reaches a much larger audience and is much more likely to solicit a positive response
02:03 PM djsftree[m]: i've tried, the people that say they will help are busy. My brain can't figure it out. I'm soooooo close.
02:03 PM djsftree[m]: hence, calling out to the hundreds here.
02:04 PM CaptHindsight[m]: https://ameridroid.com/products/rock5-model-b $145 almost in stock

02:05 PM djsftree[m]: Please, someone help. You're my only hope. Paypal payment waiting.
02:05 PM CaptHindsight[m]: djsftree: try the LCNC forum
02:06 PM CaptHindsight[m]: I forget wasn't Turboss looking at helping on the GUI side?
02:06 PM djsftree[m]: yes, but not the kins
02:06 PM CaptHindsight[m]: and lcvette for your comp?
02:07 PM djsftree[m]: i'm not even ccertain i need a homing comp.
02:07 PM CaptHindsight[m]: #qtpyvcp:matrix.org
02:07 PM CaptHindsight[m]: lcvette tends to be in there, I think he is really busy as well
02:08 PM djsftree[m]: I'm so close

02:09 PM djsftree[m]: just the DH left
02:09 PM djsftree[m]: Do you know any linuxCNC consultants anywhere?
02:09 PM CaptHindsight[m]: djsftree: how are those robots? I looked at them when they first came out
02:09 PM djsftree[m]: Like people on a phone that charge for it.
02:10 PM CaptHindsight[m]: I'm really busy as well
02:10 PM CaptHindsight[m]: what exactly do you need?
02:10 PM djsftree[m]: CaptHindsight[m]: Wonderful! Holds 5um repeatability.
02:10 PM djsftree[m]: CaptHindsight[m]: DH parameters
02:11 PM CaptHindsight[m]: http://linuxcnc.org/docs/devel/html/motion/dh-parameters.html
02:12 PM djsftree[m]: Been trying that for days now. I just need someone who knows what they're doing to provide them and bill me for the time to figure it out.

02:13 PM CaptHindsight[m]: if I get time in the next 48 hours I'll look at your numbers
02:14 PM XXCoder: djs is that vismach?
02:14 PM CaptHindsight[m]: are those your current numbers? ^^^
02:18 PM * djsftree[m] uploaded an image: (487KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/HtaVbdEQGcONiTxYXTejxmvf/image.png >
02:18 PM djsftree[m]: yes, vismach
02:19 PM XXCoder: you made it?
02:20 PM djsftree[m]: sim here
02:20 PM djsftree[m]: https://github.com/djsftree/linuxcnc_meca500/tree/main/linuxcnc/configs/sim-meca500
02:21 PM XXCoder: cool :) I made vismach of 3axis_tutorial quite a while ago
02:21 PM djsftree[m]: the vismach, yes with some help from satiowadahc
02:22 PM djsftree[m]: I made a VTK model here
02:22 PM djsftree[m]: https://github.com/djsftree/linuxcnc_meca500/blob/main/share/models/meca500.py
02:22 PM CaptHindsight[m]: djsftree: I'd post on the forums
02:23 PM djsftree[m]: Is there a job posting section?
02:27 PM CaptHindsight[m]: just post in the same forum as the link I post about DH parameters
02:27 PM CaptHindsight[m]: maybe add $paying gig$
02:32 PM rs[m]: djsftree: i think rene_dev has converted an arm to linuxcnc
02:32 PM CaptHindsight[m]: `djsftree https://forum.linuxcnc.org/10-advanced-configuration start a new thread here
02:33 PM CaptHindsight[m]: post all your links and as much info as you can
02:33 PM CaptHindsight[m]: probably be done by Friday
02:35 PM CaptHindsight[m]: rs: I did a bunch as well
02:35 PM CaptHindsight[m]: I get all the weird stuff
02:40 PM CaptHindsight[m]: I am getting a weird error with LCNC 2.9 and kernels >5.10, core dump signal11
02:40 PM CaptHindsight[m]: only with Debian
02:41 PM CaptHindsight[m]: no problem with the Gentoo builds even with 5.19 kernels
02:49 PM JT-Shop: no problem for me with Debian 9-13

03:07 PM perry_j1987: hmm odd relay isnt turning on all of a sudden
03:12 PM perry_j1987: now its working
03:12 PM perry_j1987: so odd
03:14 PM XXCoder: TurBoss: you on?
03:16 PM Loetmichel: hurrhurr... just listened to a youtube video of "in the hall of the mountain king": first comment: "our chemistry teacher always played that in the last 5 minutes of a test"... 157 answers to that with "evil! I love it!" :)
03:22 PM roycroft: grr
03:22 PM roycroft: i'll need my new filament in an hour and a half, and it looks like it's not going to be delivered today
03:23 PM XXCoder: aw :(
03:25 PM Tom_L: JT-Cave is the build master
03:27 PM roycroft: after today i'll have one day of printing left before the hardware drawers n the wall are completely empty
03:27 PM roycroft: so i guess i'm getting anxious to finish that part
03:28 PM XXCoder: I bet lol
03:28 PM * roycroft has been working on this project since early may
03:28 PM XXCoder: curious what finished print look like. I bet bed is full of boxes lol
03:29 PM roycroft: the drawers are more full than i thought they would be, but there's still plenty of room for the as yet uncataloged/unorganized fasteners
03:29 PM roycroft: i'm printing 2"x4" (nominal) boxes right now, and i print three to a batch
03:30 PM roycroft: when i do the 4"x4" i print them individually
03:30 PM roycroft: 2"x2" i print 9 to a batch
03:30 PM roycroft: so sometimes the print bed is pretty full, but often it's pretty empty
03:32 PM XXCoder: not too bad then lol
03:34 PM roycroft: printing a bunch at a time doesn't save all that much time, and when a spool of filament is running low, i risk ruining a number of boxes if i run out mid-print, vs. one or a few if i print less at a time
03:35 PM roycroft: so i'm not crowding them
03:37 PM XXCoder: yeah
03:53 PM CaptHindsight[m]: oh you can't start from the middle of a print?
03:53 PM perry_j1987: i perfer one at a time too
03:53 PM perry_j1987: always sucks when one looses adhesion and wipes out the rest of the parts heh
03:54 PM XXCoder: capt if you know z I guess you can just edit gcode, then just manually heat up and start print
03:54 PM XXCoder: lot of time its not really recoverable
03:54 PM roycroft: if i knew exactly when i ran out of filament i could resume after reloading
03:55 PM roycroft: but i don't have a filament out sensor
03:55 PM roycroft: that might be something i'll look into in the future
03:55 PM XXCoder: can easily make one
03:55 PM XXCoder: something that changes state when theres no filament
03:55 PM roycroft: the nice thing about the 3.5kg spools is that it's not much of a worry
03:56 PM XXCoder: yeah
03:56 PM XXCoder: oh talking about spools, hows your cat so far?
03:56 PM JT-Shop: 4 nice days in a row starting Thursday
03:57 PM roycroft: i've had no problems with the filament "falling over" since i last reported it a week and a half or so ago
03:57 PM roycroft: i'm back to 1kg spools now
03:58 PM XXCoder: and the cat? lol
03:58 PM roycroft: she's doing fine
03:58 PM XXCoder: thats good :)
03:59 PM roycroft: now that it's cooled off, she has her energy back
03:59 PM roycroft: i think it was a combination of fleas + hot weather that was getting her down
03:59 PM XXCoder: and presumely retaining more blood with less fleas
03:59 PM roycroft: it looks like nice weather hear for the next week, then it is supposed to get hot again
04:00 PM roycroft: right before my vacation
04:01 PM XXCoder: yeah. I'll try to get enough energy to do some yard work
04:01 PM XXCoder: its hell on me
04:01 PM XXCoder: heat just makes it worse
04:02 PM roycroft: i have to haul my counter top back outside to sand it
04:02 PM roycroft: and to radius the edges
04:02 PM roycroft: but i have a meeting right after work today, and a board meeting this evening, so i probably won't get to any of that until tomorrow at least
04:03 PM XXCoder: yay meetings
04:03 PM roycroft: i'm also thinking about painting the wall behind my new cabinets before i install the lumber rack, and if i do that i want to do it before i install the counter top
04:03 PM XXCoder: so many of those does nothing but burn time
04:03 PM * roycroft has too many meetings :(
04:03 PM roycroft: the one right after work should be productive
04:04 PM roycroft: the board meeting will be a board meeting
04:04 PM roycroft: this will be the third one on the same topic, and i don't expect we'll get any farther than we did during the first two
04:04 PM roycroft: there will be lots of discussion and disagreement, and then we'll run out of time
04:14 PM JT-Shop: do you follow Robert's Rules of Order in your meetings?
04:14 PM zincboy[m]: We need to have a meeting about how we can improve the efficiency of our meetings. How about a bi-weekly 2 hour slot? :P
04:15 PM roycroft: no, we don't
04:15 PM * JT-Shop used to spend 1/2 of a day preparing for meetings
04:15 PM roycroft: we follow a set of unwritten rules as best as people can remember them
04:15 PM roycroft: and often argue about the rules
04:15 PM JT-Shop: I guess Roberts is more for public meetings
04:15 PM roycroft: we follow the same unwritten rules in both our public and private meetings
04:16 PM roycroft: today's board meeting is a private one
04:16 PM roycroft: the difference is that in the private meetings, board members argue amongst themselves about the rules
04:16 PM roycroft: in the public meetings, members call out board members for not following the rules
04:20 PM Tom_L: hoovering around 100F most of the week
04:20 PM Tom_L: 94F currently
04:25 PM roycroft: the nice thing is that only is it not as hot as it has been, it cools off faster at night
04:26 PM roycroft: i had a few nights where it stayed hot in the house all night and i had a hard time sleeping
04:26 PM XXCoder: i thankfully have dual hose ac
04:26 PM XXCoder: best thing I ever bought
04:27 PM -!- #linuxcnc mode set to +v by ChanServ
04:30 PM Tom_dev: got a tiny sd adapter with my rpi and finally found some similar so i'm grabbing a couple
04:30 PM Tom_dev: https://www.aliexpress.com/i/2251832630070572.html

04:40 PM Tom_dev: wanna try one on my router usb and see how the 'shared storage' works on it
04:50 PM JT-Shop: https://www.amazon.com/gp/product/B07G5JV2B5
04:50 PM JT-Shop: that one is usb 3.0 only
04:51 PM JT-Shop: bought it for the truck music but the truck only does usb 2.0
04:51 PM Tom_L: i got a couple of the little ones to try as well
04:52 PM Tom_L: i'm sure once they find i have them they will dissappear
04:52 PM * JT-Shop got a shim made and installed between the cassette and the frame of the e-bike now to finger out why the derailleur is out of wack
04:53 PM JT-Shop: hide them lol
04:53 PM Tom_L: i'd forget where they were..
04:53 PM Tom_L: i might anyway
04:53 PM JT-Shop: I know how that goes
04:55 PM JT-Shop: a friend that runs a liqueur/hunting store was telling me her dog got out and killed her rooster so I texted my neighbor and asked her if she had any extra roosters... I have a rooster to deliver tomorrow
04:55 PM Tom_L: heh
04:55 PM JT-Shop: the neighbor had 3 roosters and the two big ones kept picking on the young one
04:55 PM JT-Shop: so he will be in rooster heaven tomorrow night
04:57 PM Tom_L: your dd copy line should work on rpi images too right?
05:02 PM JT-Shop: yep
05:03 PM jdh: you should never need a shim on a bike
05:08 PM JT-Shop: when you build an e-bike you might need a shim...
05:10 PM Tom_L: how would you copy the sd content to an iso image?
05:10 PM Tom_L: i generally do all that in windows and have never used dd
05:11 PM JT-Shop: I've never tried to copy the image to an iso just the other way round
05:11 PM Tom_L: yeah
05:11 PM Tom_L: maybe something like /dev/sda/* ?
05:12 PM JT-Shop: looks like the X axis on the ender is not square to the Z axis
05:12 PM JT-Shop: I don't think it's just a copy
05:12 PM Tom_L: probably not
05:12 PM JT-Shop: gotta be careful with d(isk) d(estroyer)
05:13 PM JT-Shop: gotta make sure if an of point to the right things :)
05:13 PM Tom_L: i know
05:13 PM Tom_L: that's why i've never used it :)
05:14 PM Tom_L: i got plenty of ssd to test on though

05:14 PM JT-Shop: the status=progress is nice so you can see things happening
05:15 PM Tom_L: mine dumped so quick i had to wait for the buffer and wasn't quite sure when it was actually done
05:15 PM Tom_L: that link isn't quite what i want
05:15 PM JT-Shop: that link was just copying the iso to the sd

05:17 PM Tom_L: never heard of clonezilla
05:17 PM JT-Shop: I used to use clonezilla all the time copying hd's
05:18 PM Tom_L: i used to use ghost but don't remember what i use now.. haven't done it in quite a while
05:19 PM Tom_L: i know the last time i did, i got the 2 ssd backwards
05:19 PM Tom_L: :)
05:19 PM JT-Shop: opps
05:19 PM Tom_L: i will unplug all unused ssd when i'm doing something like that
05:20 PM Tom_L: it was a test anyway
05:20 PM JT-Shop: that's a good idea and why my m.2 on the test pc has a new os now
05:20 PM JT-Shop: I mistook it for the 240GB drive and it's a 250GB drive
05:20 PM JT-Shop: oh well
05:21 PM Tom_L: the only way i can tell is the ssd identifier but if they're the same model it's nearly impossible
05:21 PM Tom_L: that's what screwed me up
05:24 PM CaptHindsight[m]: no meetings, ask questions, post truthful progress, get shit done...... but what would management do?
05:25 PM Tom_L: watch in amazement
05:26 PM Tom_L: or dumbfoundedness
05:28 PM * CaptHindsight[m] is literally cutting rubber today
05:29 PM CaptHindsight[m]: soft rubber, the waterjet shop said that they could hold a few thou for accuracy, I asked them how do you measure the edge of a cloud?
05:29 PM Loetmichel: fun stuff, CaptHindsight[m]. had to do a few 100 3mm thick EMI gaskets for Dsub9 plugs made of silver dust infused silicone... that was a PITA to do on the CNC router.
05:29 PM CaptHindsight[m]: cryo cooled and then machined
05:30 PM Loetmichel: cryo would work, yes. sadly i had no chance for that
05:30 PM CaptHindsight[m]: Loetmichel: this stuff is closer to a sponge than a solid
05:30 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14049&g2_imageViewsIndex=1
05:30 PM CaptHindsight[m]: i saw a video of a DIYer that used hypodermic needs as cutting tools for silicone rubber
05:31 PM Loetmichel: the stuff i had to mill is more like the classic construction silicone
05:31 PM CaptHindsight[m]: >10k rpm using the angled tip of the needle as a cutting tool
05:31 PM Loetmichel: and i used a 0.8mm "single flute" end mill
05:32 PM CaptHindsight[m]: https://vimeo.com/236164661
05:33 PM Loetmichel: nice idea
05:33 PM CaptHindsight[m]: Loetmichel: I have some gum rubber that is what they use for pencil or pen erasers as well
05:33 PM Loetmichel: dont know how good a stainless steel syringe needle will cope with silver dust though
05:33 PM CaptHindsight[m]: it flakes apart when you rub it too hard
05:34 PM CaptHindsight[m]: like an eraser
05:34 PM Loetmichel: its actually pretty funny
05:34 PM Loetmichel: those 3mm thick silicone sheets are not only INSANELY expensive... they are also HEAVY
05:35 PM Loetmichel: (100mm by 100mm by 3mm about 300 eur IIRC)
05:35 PM Loetmichel: they are probably more silver than silicone
05:35 PM CaptHindsight[m]: Loetmichel: is the silver for heat transfer?
05:35 PM Loetmichel: (very high conductivity)
05:35 PM Loetmichel: no. EMI gasket material
05:36 PM CaptHindsight[m]: electrical or thermal?
05:36 PM CaptHindsight[m]: ah ok
05:36 PM Loetmichel: they are for shielding
05:36 PM CaptHindsight[m]: well silver is expensive compared to copper, why I use copper for things like that
05:37 PM Loetmichel: copper oxidizes
05:37 PM Loetmichel: silver apparently not if in silicone
05:38 PM Loetmichel: ah, my bad
05:38 PM Loetmichel: not DSUB9, DVI
05:49 PM CaptHindsight[m]: copper properly mixed into silicone is fine, the areas of the gasket kept under pressure will not oxidize
05:49 PM CaptHindsight[m]: the areas in contact with the parts they are sealing
05:50 PM CaptHindsight[m]: otherwise copper wires would always require solder or similar to keep the oxygen away from it, but we do see that wire nuts work if properly tightened
05:51 PM CaptHindsight[m]: and the silicone or polymer film insulator keeps the oxygen off the copper as proven with "wires"
06:02 PM perry_j1987: lol why isnt there a calculator on the linuxcnc distro lol
06:03 PM zincboy[m]: Accessories/Calculator?
06:15 PM CaptHindsight[m]: perry_j1987: depends on the desktop chosen
06:15 PM CaptHindsight[m]: perry_j1987: I like speed crunch
06:16 PM zincboy[m]: Yes, I use xfce so it might be different for the others.
06:16 PM CaptHindsight[m]: https://heldercorreia.bitbucket.io/speedcrunch/
06:16 PM CaptHindsight[m]: zincboy: so do I :)
06:17 PM CaptHindsight[m]: zincboy: my favorite thing about XFCE now is right click to get the application drop down
06:18 PM zincboy[m]: My desktop is almost never visible :)
06:18 PM CaptHindsight[m]: a few apps still make you press Enter or I'd use only the mouse 99% of the time
06:18 PM rmu: CaptHindsight[m]: silver is a better conductor than copper. conductive glue/epoxy also usually contains silver particles. very small silver particles are easy to produce. that could be the reasons.
06:19 PM CaptHindsight[m]: rmu: nah it's the legacy of silver particles, I make conductive inks, paints , resins etc
06:20 PM FinboySlick: perry_j1987: If the default shell is bash and it's simple arythmetics you can always echo $(( 2 + 2 ))
06:20 PM rmu: http://qalculate.github.io/
06:20 PM CaptHindsight[m]: copper almost always make more sense and saves you $, but the copper coating vendors charge about the same for copper as silvers, inks, coatings etc
06:21 PM rmu: $ don't matter in loetmichel's application
06:22 PM FinboySlick: perry_j1987: I think it only does integer math anyway though.
06:22 PM CaptHindsight[m]: rmu: heh, not if his boss knew :)
06:22 PM FinboySlick: perry_j1987: There's also the 'bc' command.
06:25 PM FinboySlick: andypugh: Totally leaving this here and pulling you from something important to tell you to make more videos.
06:25 PM CaptHindsight[m]: rmu: any news from ueste4rdays LCNC meeting?
06:25 PM CaptHindsight[m]: wow yesterdays
06:26 PM CaptHindsight[m]: LCNC moving the Mac's? Andoid? German as the main language?
06:27 PM FinboySlick: btw, Loetmichel, how come your boss hasn't bought you a Datron yet? I've seen that old gantry mill for at least a decade now.
06:28 PM CaptHindsight[m]: FinboySlick: he should get a raise fist then a datron
06:28 PM XXCoder: loet needs pay rise twice
06:29 PM FinboySlick: Heh, the way things are going in Germany, he might just ask to get paid in electricity :P
06:29 PM CaptHindsight[m]: we should petition the German PanzerWaffels, no more EMI until loet gets a raise
06:30 PM CaptHindsight[m]: or gas for heat
06:30 PM XXCoder: I guess solr panels is in very high demend at germany now
06:30 PM CaptHindsight[m]: from the press a few years ago I thought Germany was near 100 based on solar and wind
06:30 PM andypugh: CaptHindsight[m]: Mainly we decided that we should try to go through PRs collectively every now and again.
06:31 PM CaptHindsight[m]: andypugh: thanks
06:31 PM andypugh: And that we should release 2.8.3 today and 2.9 “soon”
06:31 PM CaptHindsight[m]: I'm pretty sure you won't let killing RTAI slip passed you
06:33 PM CaptHindsight[m]: I've been using 2.9 since some many months
06:34 PM XXCoder: pardon me if im way behind, but is linuxcnc purely python 3 now?
06:34 PM Tom_L: yes
06:34 PM Tom_L: 2.9
06:34 PM XXCoder: nice
06:34 PM CaptHindsight[m]: the new preempt_rt kernels are terrible for older Intel latency, all that patching for exploits maybe
06:34 PM XXCoder: any work done on vismach?
06:34 PM andypugh: 2.9 is, at the moment. Python 3, GTK3, Buster + and preempt-rt only.
06:35 PM CaptHindsight[m]: RTAI has stalled out somewhere in the low 5.x's
06:35 PM andypugh: Actually, that last but is not true, it’s uspace only. You can still use an RTAI kernal through LXRT
06:35 PM CaptHindsight[m]: needs an assembly guru to make some changes
06:35 PM andypugh: And, probably, Xenomai the same way.
06:35 PM FinboySlick: GTK3... Who was the poor soul charged with the port?
06:36 PM andypugh: What we don’t have right now is kernel-space realtime in 2.9
06:36 PM CaptHindsight[m]: wasn't the old plan to move RTAI to user space anyway?
06:36 PM andypugh: GTK3 was mainly done by rene-dev5 I think. Though I had to do a bit myself on the lathe macros.
06:37 PM CaptHindsight[m]: I get a core dump signal 11 with lcnc 2.9 and a kernel >3.10rt as soon as Axis loads
06:37 PM perry_j1987: sorry didnt see anyone responded heh
06:37 PM FinboySlick: If you stay strictly within what they decided an application should look like, it's not so bad. But as the def for lxterminal, gtk3 was a nightmare.
06:38 PM perry_j1987: the stock iso installed xfce
06:38 PM perry_j1987: and no calculator heh
06:38 PM FinboySlick: It's still not 100% capable of dupplicating what we needed and they're already working on gtk4.
06:38 PM CaptHindsight[m]: perry_j1987: go to the repos and get one that you like
06:40 PM CaptHindsight[m]: CaptHindsight: xcalc is probably the lightest one vs maybe command line and python
06:40 PM FinboySlick: perry_j1987: 'galculator' is my go-to if you want a GUI.
06:40 PM CaptHindsight[m]: perry_j1987: ^^
06:41 PM CaptHindsight[m]: http://galculator.mnim.org/
06:41 PM CaptHindsight[m]: FinboySlick: I am fully fake offended
06:42 PM perry_j1987: it doesnt matter what "i" like
06:42 PM perry_j1987: the stock iso "didnt" have a calculator heh something i bet we all use often with machines
06:42 PM perry_j1987: i jsut thought it kinda comical heh
06:42 PM perry_j1987: aye i know how to get calcs lol
06:42 PM perry_j1987: it was just funny to me that it was stripped out of the stock iso
06:42 PM perry_j1987: someone went out of their way to strip it when making the iso
06:42 PM CaptHindsight[m]: perry_j1987: obey, don't calculate
06:42 PM zincboy[m]: What do you mean? I am running a the stock iso and it has a calculator at least in xfce?
06:43 PM perry_j1987: the iso i downlaoded from the site didnt
06:43 PM perry_j1987: i did nothing other than install it all stock
06:43 PM perry_j1987: with 2.8.2-11
06:44 PM zincboy[m]: Hmm. I started with the 2.8.0 version for that install so maybe that is the difference.
06:45 PM perry_j1987: stripped the threads in my fixture
06:45 PM perry_j1987: so think its time to pack up and head home for the day lol
06:46 PM CaptHindsight[m]: could be worse, you could have snapped several glass rods while tuning the grippers
06:46 PM perry_j1987: im going to order some helicoils and see how that works never used em
06:46 PM CaptHindsight[m]: perry_j1987: use thread inserts
06:47 PM CaptHindsight[m]: properly installed they work great
06:47 PM Loetmichel: FinboySlick: took me 3 years to get the $2k for that gantry. You think that stingy one would get me a real machine?
06:47 PM perry_j1987: CaptHindsight[m] like helicoils?
06:47 PM perry_j1987: or something diff
06:47 PM CaptHindsight[m]: insets 50 cents ea, inset tool $40
06:47 PM CaptHindsight[m]: helicoils
06:47 PM perry_j1987: k
06:48 PM CaptHindsight[m]: also some similar, you just have to be sure to properly install them
06:48 PM Loetmichel: XXCoder: i GOT a pay rise lately.
06:48 PM Loetmichel: now 3400 eur a month instead of 3050 eur... Wooo me!
06:49 PM FinboySlick: Loetmichel: Congrats. So now all you need is the mill.
06:49 PM Loetmichel: ... the only pay rise in 13 years btw
06:49 PM CaptHindsight[m]: you can hire more mechanics now
06:49 PM perry_j1987: k heading out now g'night guys
06:49 PM CaptHindsight[m]: 5% peer year
06:49 PM CaptHindsight[m]: per even
06:50 PM FinboySlick: Loetmichel: It's truly shameful. Working for the defence and security industry and not having billions swinging around everywhere.
06:51 PM Loetmichel: well, i dont know about billions. being paid "union" wage would be fine though.
06:54 PM Loetmichel: ATM we are getting a new IT (all PC, server, swiches, network, the whole works)... i think that is more needed, considering our fileserver is still running 2003sbs... maybe being sold to a big worldwide company and the old stingy boss going into retirement IS a good thing ;)
06:54 PM roycroft: i'll pay you billions to work for me
06:54 PM roycroft: in dogecoin
06:55 PM Loetmichel: roycroft: nah, thanks. Still have a bit of BTC in a wallet... that i forgot the passphrase of
06:55 PM FinboySlick: Loetmichel: You secure ATMs too? I don't know how wise it is for a company to underpay the people in charge of securing ATMs.
06:56 PM Loetmichel: nah. we just do secure computers and peripherials against side channel attacks (SDIP-27)
06:57 PM Loetmichel: btw: until recently every ATM here in germany ran under winNT. so much for "secure"
06:57 PM Loetmichel: s/every/nearly every
06:57 PM roycroft: i thought they ran os/2
06:57 PM XXCoder: Loetmichel: but not second one? ;) congts thoi
06:58 PM FinboySlick: Loetmichel: It's a valid strategy actually. Kind of like having a manual transmission as an anti-theft device ;)
06:59 PM Loetmichel: roycroft: nope. AFAIR they phased out OS2 in 2005 or so
06:59 PM FinboySlick: I miss NT4.
06:59 PM XXCoder: well, as long as its under long term support so patches is still coming its fine. its very well known and stable after years iof that
06:59 PM XXCoder: though at some point it gets too old
06:59 PM Loetmichel: well, thats only viable in the US, FinboySlick. over here virtually everyone can drive stick
07:00 PM Tom_L: FinboySlick, i still have NT4 loaded on a pc :)
07:00 PM CaptHindsight[m]: Loetmichel: over here it's like showing someone a rotary phone
07:01 PM CaptHindsight[m]: I just upgraded from win7 to 11
07:01 PM XXCoder: I techinically can drive stick, but its been couple decade since
07:01 PM CaptHindsight[m]: the PC was not network connected since 2015
07:01 PM XXCoder: few years ago, I upgraded from windows 7 to xfce mint 19.1
07:01 PM XXCoder: currently on 10.3
07:01 PM FinboySlick: Honestly, if they could fit the latest directX and hardware drivers on NT4, I don't see what I'd be missing from the OS itself. Its job is to run my programs.
07:01 PM ZincBoy[CAON][m]: Yay, Discord bridge is back up 🙂
07:02 PM ZincBoy[CAON][m]: With one heck of a delay though.
07:02 PM Loetmichel: the other way around is also funny
07:02 PM Tom_L: ZincBoy[CAON][m], takes time to wind it up
07:02 PM CaptHindsight[m]: ZincBoy[CA, ON]: i find that discord is just too silly even for me
07:03 PM Loetmichel: <- still has an IBM Thinkpad 600e (P3, 384MB ram) that runs an Ubuntu 14.4 withput issues (after i installed an IDE SSD)
07:03 PM ZincBoy[CAON][m]: I have a bunch of other channel on discord so I am trying to keep from running a 4th chat client.
07:03 PM CaptHindsight[m]: how is it that everyone is awake at the same time today?
07:03 PM CaptHindsight[m]: oh cept for JT
07:04 PM Tom_L: he's either chopping wood or chasing chickens
07:04 PM Tom_L: no.. he was fixing his ebike i think
07:04 PM FinboySlick: Loetmichel: See, it's that attitude that keeps you away from the Datron. You're showing your boss that you love old clunky stuff.
07:04 PM CaptHindsight[m]: I'm in his time zone and I went to bed 2 hours after he got up today
07:05 PM Tom_L: sounds like a you problem
07:05 PM Tom_L: i am as well
07:05 PM CaptHindsight[m]: no, day is just at the wrong time
07:05 PM CaptHindsight[m]: last night was an extra late one
07:06 PM FinboySlick: CaptHindsight[m]: I had a warm fuzzy feeling thinking I was included in that 'everyone'.

07:49 PM CaptHindsight[m]: so to best help I should offer to help so that someone will jump in first
08:15 PM CaptHindsight[m]: according to the internet he should post what he thinks is the right answer
08:15 PM CaptHindsight[m]: on reddit
08:15 PM CaptHindsight[m]: he should have the solution in a day or so

10:05 PM roycroft: so yeah, we had a 2 hour closed board meeting and accomplished nothing but setting the dates and times for the next two 2 hour closed board meetings to discuss the same issue
10:06 PM roycroft: but in other news, i found an old rusty hand saw at the goodwill today that looked interesting
10:06 PM roycroft: and it is
10:07 PM roycroft: it's a disston d-8 rip saw from the late 1890s
10:07 PM roycroft: and has a somewhat rare handle that has a thumb hole in it for gripping with both hands
10:07 PM roycroft: i paid $4 for it, and it should clean up very nicely
10:07 PM XXCoder: nice!
10:08 PM roycroft: yeah - i've been looking for a good vintage rip saw
10:12 PM XXCoder: you arent gonna find 100 year old saw here
10:12 PM XXCoder: not that I see anyway
10:15 PM roycroft: i've found a few decent vintage saws at the thrift shops
10:17 PM roycroft: https://www.tias.com/disston-d8-rip-saw-thumb-hole-handle-26-inch-800600.html
10:18 PM roycroft: mine is simlar to that, but with the older medallion that dates it to the 1890s
10:18 PM XXCoder: wow tiny picture. interesting rhough. wow bit expensive
10:18 PM roycroft: you can click on the pictures to enlarge
10:19 PM roycroft: you grip the saw with your dominant hand like normal through the handle
10:19 PM roycroft: then you stick the thumb of your other hand through the extra hole and wrap the rest of your hand around the top of the handle
10:19 PM roycroft: when doing heavy rip cuts it helps to be able to use both hands
10:19 PM XXCoder: so a two handed saw?
10:19 PM roycroft: yes
10:19 PM roycroft: but it can be used one-handed as well
10:20 PM roycroft: the one i got is in fairly rough condition, but i can restore it nicely
10:22 PM mrec: pcw-home: but that way I would loose the A Axis handling mechanism no?
10:47 PM pcw-home: No, you have both position (joint) and velocity modes

11:00 PM roycroft: yeah, this storm just formed
11:01 PM roycroft: the warnings went up just over an hour ago
11:01 PM roycroft: actually, an hour and 45 minutes ago
11:01 PM roycroft: we're not in danger here, but there are burn scars near here from the fires last year and the year before
11:02 PM roycroft: that's where the flooding might happen
11:02 PM XXCoder: ok
11:02 PM XXCoder: here land is quite high so flooding is a rarity
11:03 PM roycroft: i can't remember the last time we had even a single raindrop in august
11:03 PM roycroft: sometimes it rains in early july a bit, but after mid-july, there's never any rain until september
11:03 PM XXCoder: my old home was only minutes away from inlet sea, but it was also over 100 feet higher. 250feet? cant remember now
11:03 PM roycroft: except today
11:03 PM XXCoder: walking back up was hell
11:06 PM XXCoder: I have simple idea of using cermic heater to make a diseccant dryer thinbg
11:06 PM XXCoder: but problem I have no idea how to design it so cermic heaters dont melt wires, but is not sticking up out of lid
11:20 PM roycroft: we just had lightning and thunder
11:21 PM roycroft: maybe get a reptile lamp, xxcoder
11:21 PM roycroft: that's what i use in my fermenterator when i need to actually heat the wort above ambient temperature
11:21 PM roycroft: and we just had a power glitch
11:21 PM XXCoder: I use special cermic dryers that needs 270c
11:22 PM roycroft: oh, a reptile lamp won't get that hot
11:22 PM XXCoder: yeah
11:22 PM roycroft: and some of my servers just disconnected
11:22 PM roycroft: i wonder why - i have upses on everything and power conditioners
11:23 PM roycroft: at least it's going to be nice and cool tonight when i go to bed
11:24 PM * roycroft had better go check on the servers
11:24 PM CaptHindsight[m]: you know that feeling when you first get machine going and you change a few settings and tighten a few screws and then it just rips with no errors for an hour of the worst you throw at it?
11:24 PM XXCoder: roy might be EMF rather than cut of power
11:26 PM CaptHindsight[m]: Portland has angered the gods
11:27 PM roycroft: that's what it was, i think
11:27 PM roycroft: the upses are fine
11:27 PM roycroft: but all the machines that are connected to one of them are rebooting
11:28 PM XXCoder: slight l;ight flicker here
11:28 PM roycroft: are you getting some weather?
11:28 PM CaptHindsight[m]: just for reference, no power issues here :)
11:28 PM roycroft: the thunderstorm warning and flash flood warning here is very localized - just for north central lane county
11:29 PM roycroft: and the doppler radar doesn't show any rain outside my local area
11:29 PM CaptHindsight[m]: we had storms 2 night ago and the day before that after no rain for maybe 2 weeks
11:29 PM XXCoder: capt we havent had rain for weeks
11:29 PM CaptHindsight[m]: all the ponds around here were just mud pits
11:29 PM XXCoder: it used to be case that we had rain in least once a week here
11:30 PM XXCoder: its rainforest biome after all
11:30 PM XXCoder: but not the case for pretty long time
11:30 PM CaptHindsight[m]: I'm happy that Chicago has stayed just north of the hot hot weather this year
11:30 PM roycroft: when i lived in bellingham i remember that we got rain pretty much year-round
11:30 PM roycroft: as did seattle (but not as much)
11:31 PM roycroft: it's when i moved to eugene that the no rain in july and august stuff started for me
11:31 PM CaptHindsight[m]: 70's here all this week again, low 20c
11:31 PM roycroft: low 30s here until the middle of next week, when it's forecast to get back into the upper 30s
11:32 PM roycroft: but only 28 today
11:32 PM roycroft: this august rain is kind of freaky
11:33 PM CaptHindsight[m]: we have had stretches of 30c days but nothing higher
11:34 PM roycroft: this rain is supposed to be gone by midnight
11:34 PM roycroft: but then again, a couple hours ago it was never supposed to be here in the first place
11:34 PM CaptHindsight[m]: we usually get at least a couple of 40c-ish days by now
11:34 PM roycroft: so all bets are off tonight
11:34 PM roycroft: we've not hit 40 yet this year, thank goodness, but we did get to 39
11:35 PM CaptHindsight[m]: https://www.wunderground.com/forecast/us/or/portland
11:35 PM CaptHindsight[m]: look rough next week
11:36 PM roycroft: yeah
11:36 PM roycroft: and we're going to get back up to 37 here on wednesday next
11:36 PM roycroft: and it looks like pdx is getting some rain tonight too
11:37 PM XXCoder: wed ouch (next week one)
11:37 PM XXCoder: https://www.google.com/search?client=firefox-b-1-lm&q=tacoma+weather
11:37 PM roycroft: https://www.wunderground.com/forecast/us/or/lincoln-city/44.96,-124.02
11:37 PM roycroft: that's where i'll be headed on the 22nd
11:37 PM roycroft: looks promising :)
11:37 PM CaptHindsight[m]: XXCoder: similar here https://www.wunderground.com/forecast/us/il/chicago
11:38 PM CaptHindsight[m]: roycroft: you need to move to the coast :)
11:38 PM XXCoder: i live near inlet sea coast :P
11:38 PM CaptHindsight[m]: early fall weather
11:41 PM roycroft: some day i'd like to move to the coast
11:41 PM roycroft: but coast houses are made out of unaffordium, so it won't be easy to do
11:41 PM CaptHindsight[m]: I'm working in a glass factory where they don't have any E-stops on their current equipment
11:42 PM * roycroft is watching a glass blowing show on netflix at the moment
11:42 PM CaptHindsight[m]: since most of their work has been manual or motor powered but manual operation
11:43 PM CaptHindsight[m]: are they wearing their ddidymium glasses?
11:43 PM CaptHindsight[m]: didymium heh
11:44 PM roycroft: they are not
11:46 PM XXCoder: ill never risk my eyes like that
11:47 PM roycroft: they all wear safety glasses
11:47 PM roycroft: but they look pretty clear
11:47 PM CaptHindsight[m]: the glassblowers talk about getting burns in the retinas that last for a couple days
11:47 PM XXCoder: capt probably from UV emitting from molen glass?
11:48 PM XXCoder: one of sources of UV if I recall right anyway
11:48 PM roycroft: maybe they have lenses with a very thin didymium coating
11:48 PM CaptHindsight[m]: they will be working with metal additives that give the glass colors or effects that flare up in a range outside their usual protective eyewear
11:48 PM roycroft: yes
11:48 PM roycroft: very much so
11:48 PM CaptHindsight[m]: then they have to go double layer or use a welding helmet
11:49 PM XXCoder: ahh
11:49 PM CaptHindsight[m]: XXCoder: yes UV, sodium flare is yellows and then IR
11:49 PM XXCoder: ok I remembered some correctly then
11:50 PM CaptHindsight[m]: if I go out in sun with the didymium you eyes sort of adjust to no yellow
11:50 PM CaptHindsight[m]: then you take them off and wham the world is so full of yellows
11:50 PM CaptHindsight[m]: it makes the reds really pop with the didymium glasses on
11:50 PM roycroft: the show i'm watching is "blown away"
11:51 PM CaptHindsight[m]: hah
11:51 PM roycroft: if you enjoy art glass it's a fun dhow to watch
11:51 PM roycroft: show
11:51 PM XXCoder: I love watching glass work
11:51 PM roycroft: it uses the great british bake off format
11:51 PM roycroft: a contest every show
11:51 PM roycroft: one contestant is eliminated
11:52 PM roycroft: until there are only two left
11:52 PM CaptHindsight[m]: roycroft: yeah, that is what I am automating
11:52 PM CaptHindsight[m]: all the boring repetitive stuff
11:52 PM roycroft: i'm watching the finale now
11:52 PM roycroft: for season 3
11:52 PM CaptHindsight[m]: 1 million pipes for example or blunt holders
11:53 PM roycroft: i'm not binge watching, but when the semi-final just ended i decided to go ahead and watch the final one
11:53 PM roycroft: yeah, that is boring
11:53 PM roycroft: this is not
11:54 PM roycroft: and one of the finalists does have didymium safety glasses
11:54 PM roycroft: they look really nice on the top of his head
11:54 PM XXCoder: crowned with glasses
11:54 PM CaptHindsight[m]: the people I work with mostly made scientific glass
11:55 PM CaptHindsight[m]: but it will be fun to do some glass art demos
11:55 PM CaptHindsight[m]: CNC glass lathe that spins out a bong on it's own or a lamp
11:57 PM roycroft: i've never blown glass, but i've made some stained glass pieces
11:58 PM roycroft: i enjoy it, but glass is not my primary medium by any means, and i'm not interested in it enough to ever make it my primary medium
11:58 PM roycroft: unless some day i wake up and do :)
11:59 PM XXCoder: I was thinking on using two of those https://www.amazon.com/dp/B07RT5N9W9/
