01:23 AM Deejay: moin
01:54 AM lcnc-relay: <vibram> hello
01:55 AM lcnc-relay: <vibram> I got some sensor from alibaba, i need to test them
01:56 AM lcnc-relay: <vibram> but 35$ and 0.001mm repeatability according to their spec...
04:07 AM JT-Cave: morning
04:09 AM NetPipe: expresso
04:10 AM NetPipe: ☕️
04:10 AM lcnc-relay: <Travis Farmer> Morning
04:43 AM Tom_L: morning
04:54 AM Tom_L: JT-Cave, PR #120
04:56 AM JT-Cave: thanks
04:56 AM JT-Cave: I assume there was some discussion on the proper spelling of G code LOL
04:57 AM JT-Cave: I do prefer G code myself instead of G-code
06:32 AM -!- #linuxcnc mode set to +v by ChanServ
07:21 AM JT-Cave: now back to programming
08:30 AM lcnc-relay: <Travis Farmer> "G10 L2 P0 Rn" how much can n (rotation) be? if i layout the CAD/CAM at 0deg, but it fits on the machine better at 90deg, will "G10 L2 P0 R90" work? or is it too big a rotation?
08:30 AM * JT-Cave reminds himself to add homing and unhoming to program_running
08:32 AM lcnc-relay: <zincboy_ca_on> I would normally just change the UCS in CAM and re post if I needed to rotate 90deg. I haven't tried it but I would expect the main issue would be that the machine would not move as you would expect when jogging.
08:33 AM lcnc-relay: <Travis Farmer> ok, good point
08:36 AM Tom_L: 58F
08:36 AM lcnc-relay: <Travis Farmer> 54F
08:38 AM Tom_L: comes a point changing the cam makes more sense
08:39 AM lcnc-relay: <Travis Farmer> yeah, i was just curious
08:39 AM Tom_L: group, rotate, post, done
08:39 AM Tom_L: 45 deg would be a sensible angle to call a limit
08:40 AM JT-Cave: 48°F

08:40 AM lcnc-relay: <vibram> Finally my pcp are here 🙂
08:40 AM lcnc-relay: <Travis Farmer> dang, JT gets the coldest award
08:40 AM Tom_L: JT-Cave, you ever get your probe?
08:41 AM Tom_L: my spare tips are in KC
08:42 AM JT-Cave: yes and it's wired up and connected in hal
08:42 AM Tom_L: cool
08:44 AM Tom_L: vibram, what? no SMT??
08:46 AM JT-Cave: still have a bit to do with home and unhome menu enable/disable but close
08:47 AM * JT-Cave heads for work
08:47 AM Tom_L: once in a while mdi works with the probe enabled
08:47 AM Tom_L: you might check that
08:47 AM Tom_L: has to be the right combination
08:49 AM JT-Shop: see if you can figure out the combination
08:49 AM Tom_L: later today
08:50 AM Tom_L: seems to happen the 2nd time the probe is enabled / disabled / enabled
08:51 AM lcnc-relay: <Travis Farmer> so, in a setup where the table is Z0, when the machine is at Z0, does that mean the nose of the spindle is on the table? my spindle is higher than my Z-axis box for tool-holder clearance, and my laser is below my Z-axis box by a little.
08:51 AM lcnc-relay: if i set Z0 to table, would it make sense to just probe the table, set it at laser ride height (my lowest Z action)?
08:52 AM Tom_L: depends how you define Z0
08:52 AM Tom_L: good practice is to set Z0 with the longest tool
08:53 AM lcnc-relay: <Travis Farmer> longest tool? so a short tool can't reach?
08:53 AM lcnc-relay: <vibram> Isolation for P1 7i96s
08:53 AM lcnc-relay: <vibram> With the possibility to have différential inputs
08:54 AM lcnc-relay: <vibram> And voltage divider
08:54 AM Tom_L: JT-Shop, first time thru, i run a probe subroutine and with the probe enable button enabled i'm able to use mdi commands
08:54 AM lcnc-relay: <vibram> And isolation with the cd4049/4050
08:55 AM JT-Shop: ok likely the mdi code is enabling the mdi non probing controls
08:55 AM Tom_L: yeah that makes sense
08:56 AM Tom_L: those are all mdi calls
08:58 AM Tom_L: however the jog buttons are still disabled
08:59 AM Tom_L: and as soon as i cycle the probe enable button mdi goes back to disabled
09:06 AM JT-Shop: yup it's got to be a bug in the mdi code
10:46 AM lcnc-relay: <Travis Farmer> i think i killed my FreePBX install... grumble grumble grumble 😦
10:54 AM * JT-Shop found a NIB 480v 3phase 24vdc power supply... going to use that in the control cabinet
10:54 AM lcnc-relay: <Travis Farmer> score!
10:58 AM JT-Shop: I have two huge 480v 10a 24vcd power supplies that I'll never use
10:58 AM JT-Shop: lunch time
11:12 AM lcnc-relay: <Travis Farmer> making lunch here, too
11:48 AM * roycroft is going to have a go at removing the broken pipe fitting in his compressor tank drain hole at lunch today, foregoing the meal
12:00 PM JT-Cave: nap time
01:23 PM lcnc-relay: <skunkworks8841> roycoft: I have had really good luck with a slightly bigger allen wrench or torqs bit hammered into the remaining fitting.
01:24 PM lcnc-relay: <skunkworks8841> torx
01:42 PM xxcoder: torx is such great ghetto extractor tool
02:25 PM lcnc-relay: <skunkworks8841> yes - yes it is
03:02 PM roycroft: well just about the worst thing happened
03:02 PM roycroft: i was able to get an ez-out in the drain hole of the compressor tank
03:03 PM roycroft: but when i turned it to try to remove the broken threaded bit, it galled itself to the brass (as i was concerned it might do)
03:03 PM roycroft: and then got totally stuck
03:04 PM roycroft: when i put an extension on a breaker bar to give it a bit more oompf, it startd spinning
03:04 PM roycroft: but it's spinning freely now - i anticipate that when i finally get down to being able to remove it i'll find the "teeth" clogged with brass, and a fairly smooth conical hole in the fitting
03:05 PM -!- #linuxcnc mode set to +v by ChanServ
03:16 PM roycroft: that matches the taper of the ez-ut
03:16 PM -!- #linuxcnc mode set to +v by ChanServ
03:16 PM roycroft: out
03:16 PM roycroft: so it looks like i'm going to have to completely disassemble the thing after all
03:16 PM roycroft: i'm going to look at this as an opportunity though
03:16 PM roycroft: the drain plug is a 3" plug, tapped for a 1/4" npt thread
03:16 PM roycroft: but all my drain plumbing is 1/2", except for the adapter going into the tank
03:16 PM roycroft: i should, when i do all this work, probably just bore the plug out for a 1/2" npt thread and not have to do a transition
03:16 PM roycroft: but this is like a day's work :(
03:28 PM lcnc-relay: <Travis Farmer> so nobody needs/wants a Mesa 7i80HD-16? not even for $100 USD? hmm... it is a good board... thought it would sell...
03:29 PM JT-Shop: been a whole week for sale?
03:30 PM lcnc-relay: <Travis Farmer> 3 days posted, more than a week up for sale
03:31 PM lcnc-relay: <Travis Farmer> the way people were talking on the forum, i thought it would sell fast
03:41 PM lcnc-relay: <Travis Farmer> maybe i am just too dang impatient...
04:01 PM * JT-Shop calls it a day
04:02 PM roycroft: it's kind of a niche product
04:02 PM roycroft: i'd expect it to sell within six months to a year
04:06 PM lcnc-relay: <Travis Farmer> Hmmm...
04:07 PM roycroft: that's a problem i'm facing
04:07 PM roycroft: i have a lot of stuff i want to sell
04:07 PM roycroft: and i'd like to sell it fast, but most of it needs the right buyer, so it's going to take a while
04:07 PM roycroft: either that or i mark it all down to fire sale prices
04:10 PM JT-Shop: a 7i80 is something not usually used for new projects but rather something to replace a broken one
04:11 PM roycroft: hence it's being a niche product
04:11 PM JT-Shop: or a backup for a machine that has one
04:13 PM lcnc-relay: <Travis Farmer> well, if it doesn't sell, i will keep it as a backup... just wanted a little money for my machine is all
04:14 PM JT-Shop: it will sell one day
04:15 PM lcnc-relay: <Travis Farmer> it's like my 7i73, i keep having plans to make a control panel, but with flex... i don't really need one...
04:16 PM lcnc-relay: <Travis Farmer> it is cool though...
04:16 PM JT-Shop: how does flex replace a pendant card
04:17 PM lcnc-relay: <Travis Farmer> i have a pendant... i was going to use the 7i73 to make a machine control panel. flex lets me add buttons and features that the control panel would do... i may still build it. dn't know yet
04:18 PM lcnc-relay: <Travis Farmer> *don't
04:18 PM JT-Shop: cool
04:21 PM Unterhaus_ is now known as Unterhausen
04:21 PM lcnc-relay: <Travis Farmer> though i still need control panel buttons for at-machine tool changes, rather than running to my computer... it is all not well thought out yet 😉 my hardware E-stop switch is still just taped to my desk, lol
04:22 PM Unterhausen: I just calculated some geometry, but I didn't like the answer. Shakes fist at my calculator
04:24 PM roycroft: gigo :)
04:25 PM roycroft: are you certain it's not a "my pillow" calculator?
04:25 PM roycroft: those use alternative maths
04:25 PM lcnc-relay: <Travis Farmer> MAO
04:25 PM lcnc-relay: <Travis Farmer> *LMAO
04:28 PM * JT-Shop should go and attempt to put the parking brake spring on the `82
04:34 PM JT-Shop: the job looks to be quite difficult due to the lack of work space... it has like a 1/8" gap between the shoes and the hub
04:45 PM Unterhausen: 26 degrees doesn't sound right, I blame Hewlett Packard, garage electronics company
05:05 PM -!- #linuxcnc mode set to +v by ChanServ
05:18 PM JT-Shop: https://gnipsel.com/images/C3/
05:18 PM Tom_L: i'll build here in a sec.. just walked in
05:20 PM xxcoder: you made it, or just bought to swap it?
05:21 PM Tom_L: that looks like fun
05:22 PM Tom_L: PR #121
05:23 PM JT-Shop: without the tool I made to put the parking brake springs in the C5 I never would have gotten the spring in
05:23 PM Tom_L: wire hook?
05:23 PM JT-Shop: yup
05:23 PM Tom_L: i got one on my mower that needs that
05:28 PM JT-Shop: https://gnipsel.com/images/C3/parking-brake-tool.jpg
05:28 PM Tom_L: mine isn't that fancy
05:29 PM Tom_L: wire with a hook and bent over on the other end but it's damn stiff wire
05:29 PM JT-Shop: I bent it then cut off the end
05:29 PM Tom_L: i figured so it won't pull thru
05:47 PM JT-Shop: I "think" I have 90% of the components specked out
05:50 PM Tom_L: nice
05:51 PM JT-Shop: and today 71 years ago I was born
05:52 PM xxcoder: 🎉 happy birthday
05:52 PM JT-Shop: thanks
05:53 PM lcnc-relay: <TurBoss> Ole ! Happy birthday JT-Shop
05:53 PM JT-Shop: my mother gave birth in a Quonset hut on King Salmon island and my dad had to administer ether
05:54 PM * lcnc-relay TurBoss envía confeti 🎉
05:54 PM JT-Shop: thanks
05:54 PM JT-Shop: and Alaska was not a state yet...
06:06 PM lcnc-relay: <roguish> JT-Shop: happy birthday. hey I was born in a Territory also, Hawaii, 1955
06:07 PM JT-Shop: cool and thanks
06:07 PM lcnc-relay: <roguish> JT-Shop: working on Flex.
06:07 PM JT-Shop: nice
06:07 PM lcnc-relay: <roguish> just cannot get the images in the probing to work. tried everything
06:07 PM JT-Shop: we keep improving it every day
06:08 PM lcnc-relay: <roguish> followed your instructions in the docs for Resources.
06:08 PM JT-Shop: ah you need the resources in the ini
06:08 PM JT-Shop: and you need the correct resources.py file
06:08 PM lcnc-relay: <roguish> got it all, I think
06:09 PM JT-Shop: run from a terminal
06:09 PM lcnc-relay: <roguish> does the Resources in the big menu work.?
06:09 PM lcnc-relay: <roguish> I do run from term
06:09 PM JT-Shop: yes
06:10 PM JT-Shop: CNC Flex Resources creates a resource file
06:10 PM lcnc-relay: <roguish> just did that
06:11 PM JT-Shop: sounds like a path error to me for open file
06:12 PM lcnc-relay: <roguish> does the resouces.py have to be in the .ini config directory ?
06:12 PM JT-Shop: yup
06:12 PM lcnc-relay: <roguish> so I gotta move it. ok
06:13 PM JT-Shop: https://gnipsel.com/linuxcnc/flexgui/resources.html
06:13 PM JT-Shop: down at the bottom
06:14 PM lcnc-relay: <roguish> well, shit howdy. worked now
06:14 PM lcnc-relay: <roguish> thanks
06:14 PM JT-Shop: of course it works...
06:15 PM * JT-Shop calls it a night
06:15 PM JT-Shop: say goodnight Gracie
06:15 PM lcnc-relay: <roguish> a buddy in Orlando is hunkering down for Milton the monster
06:16 PM lcnc-relay: <roguish> beer time here.
06:16 PM JT-Shop: what category is it
06:16 PM JT-Shop: vino time here
06:23 PM lcnc-relay: <roguish> think it finaly made 5
06:27 PM Tom_L: happy birthday!
06:28 PM Tom_L: roguish did you get the images working?
06:28 PM JT-Cave: Tom_L, did you test probe routines and mdi enable/disable?
06:28 PM Tom_L: no not yet
06:29 PM Tom_L: booting..
06:29 PM JT-Cave: works for me...
06:30 PM Tom_L: won't take but a sec to find out
06:30 PM JT-Cave: k
06:30 PM JT-Cave: milton looks bad ass
06:31 PM Tom_L: seems better
06:32 PM Tom_L: only thing is i made a zero axis button using mdi :)
06:32 PM Tom_L: part of the probe set routines
06:34 PM Tom_L: that can't be helped probaby
06:34 PM Tom_L: probably
06:35 PM Tom_L: gotta disable probing to set any of the axis with the probed value
06:35 PM roycroft: roguish: all your buddy needs to do is register as a democrat and he'll be perfectly safe - the jewish italian weather lasers will keep the storm away from him
06:36 PM roycroft: or are they italian jewish weather lasers?
06:36 PM * roycroft is not sure
06:37 PM JT-Cave: a jewish princess?
06:38 PM Tom_L: i need to get out there and retest the tool setter routine
06:38 PM Tom_L: don't think that will happen today
06:39 PM JT-Cave: nothing will happen today here the chickens are on the roost
06:39 PM roycroft: pew pew pew
06:39 PM roycroft: another island of blue saved from the hurricane by the space lasers
06:40 PM lcnc-relay: <pixiepaws01> Hi friends
06:40 PM xxcoder: hey
06:40 PM Tom_L: would it be possible to have a group of mdi active using a particular name?
06:40 PM Tom_L: like you did with probe_
06:40 PM roycroft: i had a mail server failure right before the end of work, and just put in an extra hour and a half fixing it
06:41 PM roycroft: so now i'm way behind schedule, but it's time to start disassembling the compressor so i can effect the repair
06:41 PM Tom_L: that would allow the best of both worlds
06:41 PM roycroft: and tom_l has planted the idea in my head that if i can elevate the tank slightly i might suffer less grief in the future
06:41 PM roycroft: i'll have to see if there's enough clearance to do that
06:42 PM lcnc-relay: <pixiepaws01> I have some "omron" optical encoders from ebay that seem to work very well. But the "Z" signal period is twice as long as the A/B signals. Anyone know why that is? It makes my zeroing logic trickier
06:42 PM lcnc-relay: <pixiepaws01> Like if you're within the zero period, you can still have 4 state transitions, which is weird to me
06:42 PM roycroft: the hardest part about all of this is lifting the compressor pump up onto the tank - it is very heavy
06:43 PM * roycroft wonders if he can somehow suspend it just above the tank while he's serivcing the tank
06:43 PM _unreal_: use the knees not the back
06:43 PM roycroft: i'm thinking of using a pulley :)
06:43 PM roycroft: if there's room
06:44 PM xxcoder: hopefully someone will know that encoder and know what the issue is
06:44 PM roycroft: it's a short shed
06:44 PM lcnc-relay: <pixiepaws01> Shouldn't the zero signal be half the period of the A/B signal periods so there's no ambiguity?
06:44 PM roycroft: not much headspace - just enough for the compressor and dust extractor
06:46 PM lcnc-relay: <pixiepaws01> Now I have to write a lot of logic which I'm not even sure will fit in the raspberry pi pico PIO instruction memory
06:47 PM Tom_L: pixiepaws, the index slot on the encoder could possibly be wider than the others if it's a fairly fine resolution encoder
06:47 PM Tom_L: kindof a guess
06:48 PM lcnc-relay: <pixiepaws01> @Tom_L it's a 20,000 count encoder. All signals look very clean on the oscilloscope. The Z slot is exactly twice as wide as the A/B slots
06:48 PM Tom_L: 4 state transitions for the quad may be but one for an index pulse
06:48 PM Tom_L: look at the timing chart on the data sheet if it gives one
06:48 PM lcnc-relay: <pixiepaws01> I have something better - an oscilloscope
06:49 PM Tom_L: but then you'd know what they expect you to expect
06:49 PM Tom_L: i thought i had omron but mine are nemicon
06:50 PM lcnc-relay: <pixiepaws01> The only way to detect zero in this case is to write logic to detect the rising edge of the Z signal when approaching in the clockwise (our counterclockwise, pick one) direction. Which means logic must detect when A/B transitions are happening while still under the Z slot and ignore them
06:50 PM Tom_L: https://www.ia.omron.com/data_pdf/guide/34/rotary_tg_e_5_1_4-10(further_info).pdf
06:50 PM lcnc-relay: <pixiepaws01> * the Z
06:51 PM Tom_L: for syncronous moves?
06:52 PM Tom_L: https://omron-russia.com/doc/sensors/encoder/E6B2.pdf
06:53 PM Tom_L: the z pulse is wider in those charts
06:53 PM lcnc-relay: <pixiepaws01> Mine looks exactly like this: https://library.automationdirect.com/wp-content/uploads/2013/05/z-pulse-timing-diagram.jpg
06:53 PM Tom_L: pdf P4
06:53 PM Tom_L: and that's what it's supposed to look like :)
06:54 PM lcnc-relay: <pixiepaws01> Which means while Z is high, you can still have 3 counts
06:54 PM lcnc-relay: <pixiepaws01> But why though? How is this an advantage?
06:54 PM Tom_L: looks the same as their published specs
06:54 PM Tom_L: what are you using the index pulse for?
06:55 PM Tom_L: generally it's used for spindle sync or synchronous axis movements
06:55 PM lcnc-relay: <pixiepaws01> Just as another guard to make sure I didn't lose counts anywhere
06:55 PM lcnc-relay: <pixiepaws01> That is, to assert that zero is where I expect it to be
06:56 PM lcnc-relay: <pixiepaws01> And fail catastrophically if it isn't
06:56 PM lcnc-relay: <skunkworks8841> Travis Farmer is the 7i80 still for sale?
06:56 PM Tom_L: way back when, the 68332 microchip had an encoder mode when the encoder spun so fast it would start reading the index pulse only
06:56 PM lcnc-relay: <pixiepaws01> The RP2040 can run at 250 MHz and has independent state machine "coprocessors" for I/O 🙂
06:56 PM Tom_L: if you're looking for zero, use the index
06:57 PM lcnc-relay: <skunkworks8841> I think I had the first 7i80 running a machine with linuxcnc
06:57 PM Tom_L: show off
06:57 PM Tom_L: :)
06:57 PM lcnc-relay: <skunkworks8841> lol
06:57 PM lcnc-relay: <pixiepaws01> Yeah if you just look for the index, you don't know if you're at 0 (1), 0 (2), or 0 (3) beecause you can still have that happen in the zero slot
06:57 PM xxcoder: 😄
06:57 PM lcnc-relay: <skunkworks8841> Hey - I worked hard for that.. testing realtime ethernet and everything
06:57 PM lcnc-relay: <pixiepaws01> That is, you can't simply reset your counter to zero when you hit the Z pulse
06:58 PM Tom_L: you'll have to keep track then
06:58 PM lcnc-relay: <skunkworks8841> (I did get the 7i80 for free from the box peter brought to one of the cnc fests..)
06:58 PM lcnc-relay: <pixiepaws01> Becuase then your 20,000 count encoder becomes a 19,997 count encoder
06:58 PM Tom_L: or find an encoder with a narrow Z pulse
06:58 PM lcnc-relay: <pixiepaws01> Yeah, I have to keep track sadly but the PIO instruction space on the RP2040 is only 32 instructions long 😦
06:59 PM lcnc-relay: <pixiepaws01> The A/B encoder program already takes up 24 instructions https://github.com/raspberrypi/pico-examples/blob/master/pio/quadrature_encoder/quadrature_encoder.pio
06:59 PM lcnc-relay: <skunkworks8841> seems like if you are worred the encoder isn't counting correctly you need to revisit your setup
07:00 PM Tom_L: skunkworks, he's worried about getting exact change back
07:00 PM lcnc-relay: <pixiepaws01> I have to come up with something clever to try and squeeze in the Z logic
07:00 PM lcnc-relay: <skunkworks8841> and if you only check the rising or falling edge of the encoder index - it should work just fine to check...
07:00 PM lcnc-relay: <skunkworks8841> *check your count.. It should be the same every thime
07:00 PM lcnc-relay: <skunkworks8841> time
07:00 PM Tom_L: z is roughly 4 counts wider though
07:01 PM lcnc-relay: <skunkworks8841> So? if you only check the rising or falling edge - it should be the same count every time
07:01 PM lcnc-relay: <skunkworks8841> Unless I am missing something.. It has been a long day
07:02 PM lcnc-relay: <pixiepaws01> skunkworks, then you're only reading either side of that signal and missing everything inside
07:02 PM lcnc-relay: <pixiepaws01> You have to look for only one "side" of that signal, that's the extra logic needed
07:02 PM Tom_L: https://www.youtube.com/watch?v=o8lezpJhfAo
07:02 PM lcnc-relay: <pixiepaws01> Yes it's easy with an FPGA
07:03 PM Tom_L: :)
07:03 PM lcnc-relay: <pixiepaws01> The trick here is implementing it in the RP2040 PIO state machine
07:03 PM Tom_L: you should give rue that challenge
07:03 PM lcnc-relay: <pixiepaws01> Why did they only make the PIO program size max 32 instructions long
07:03 PM Tom_L: he loves state machines
07:08 PM lcnc-relay: <pixiepaws01> The PIO is amazing. I just can't understand why they crippled it with max 32 instruction program size
07:09 PM lcnc-relay: <pixiepaws01> It should be possible to implement, just have to optimize the logic
07:12 PM lcnc-relay: <pixiepaws01> These knockoff encoders are great. They spec max 100kHz response which worried me initially, but I tested them to work well at > 1 MHz, at l east the differential/line driver output model
07:12 PM lcnc-relay: <pixiepaws01> They're Omron E6B2 knockoffs
07:12 PM lcnc-relay: <pixiepaws01> At least I'm 99% sure they're knockoffs. I don't know, these _are_ knockoffs right? https://www.ebay.com/itm/224990513070
07:16 PM Tom_L: i'm using some nemicon mineature series i got off some medical equipment
07:17 PM Tom_L: ball bearing .. so far they've held up great

07:18 PM Tom_L: focus ring for some kind of medical equipment
07:23 PM lcnc-relay: <pixiepaws01> Well that's definitely not a knockoff
07:24 PM lcnc-relay: <pixiepaws01> I tend to avoid repurposing old stuff becuase it's hard to find the same part numbers again for other uses
07:28 PM roycroft: well it only took an hour to get down to the tank
07:29 PM roycroft: and i had a cunning plan - if i drill a big hole in the mounting base for the compressor in the middle, i can fix the drain without having to take the mounting base off
07:30 PM roycroft: my cunning plans are generally better than baldrick's, but sometimes not, so we'll see how that goes
07:45 PM roycroft: and things are exactly as i expected - the ez-out was full of brass, and the remmants of the fitting were a smooth taper
07:46 PM * roycroft will retap for 1/2" and be done with this problem, hopefully, for good
07:46 PM Tom_L: clean it out with a pipe tap?
07:46 PM roycroft: i have to think a bit more about it though
07:46 PM Tom_L: i'd try that before going bigger
07:46 PM roycroft: a 1/2" thread might extend into the bottom of the tank a wee bit
07:46 PM roycroft: and prevent it from completely draining
07:47 PM roycroft: the answer to my conundrum will be what the local hardware store have in stock
07:47 PM roycroft: because i want to get at least the tank back in place today, and i'm not driving down to eugene for parts at this time of day
07:48 PM roycroft: the ez-out was easy to take out once i had access
07:53 PM Tom_itx is now known as Tom_L
09:10 PM roycroft: i guess i'll find out if the fix worked - i did retap for 1/4" but i'm not certain that the street elbow was able to make up enough to seal it well
09:11 PM roycroft: and i won't know until i have the whole thing reassembled
09:11 PM roycroft: but i think there's a pretty good chance it will work
09:23 PM Tom_L: plumbers putty'll fix anything!
09:31 PM roycroft: i don't want to do a janky fix
09:32 PM roycroft: i want to never have to deal with this again
09:35 PM roycroft: which means i may deal with it again one more time tomorrow or thursday
10:09 PM lcnc-relay: <big_kevin420> ill take a link, but size is the determining factor
