01:02 AM R2E4: anyone know what board I need to make the 8i20 velocity speed mode?
01:05 AM IchGucksLive: good morning from Europ
01:05 AM R2E4: morning
01:11 AM archivist: tiwake, one you write yourself
01:11 AM R2E4: Hey IchGucksLive: you know anything about the 8i20 mesa board?
01:11 AM IchGucksLive: no
01:13 AM gloops: there are people who know R2 - just dont seem to be around atm
01:14 AM R2E4: Peters probably sleeping
01:14 AM archivist: R2E4, are they step dir without the feedback to linuxcnc?
01:16 AM R2E4: 3 phase amp for ac servos
01:17 AM archivist: I just found them, yes step dir without feedback to lcnc
01:18 AM R2E4: huh?
01:18 AM archivist: we saw somebody have a problem the other day where they were badly set and one axis slowed the others kept going then the delayed caught up
01:19 AM R2E4: 3 phase torque mode amp. Where do you see step and dir?
01:19 AM archivist: lcnc had no knowledge of the error
01:19 AM archivist: http://www.motiontek.ca/index_files/ACServ4.jpg
01:21 AM R2E4: Thats not what I am talking about, but thats interesting.
01:22 AM R2E4: those drives usually have output you can send into lcnc
01:23 AM archivist: more than interesting it took the wrong path
01:23 AM archivist: you need to tee into the encoder signal
01:24 AM R2E4: am doing a bridgeport with dc servos and the customer insisted on Viper drives. Encoder into the drives and nothing back to lcnc
01:25 AM R2E4: I can t-tap the encoder and send it to lcnc?
01:25 AM R2E4: Then lcnc will correct any errors, but there will be two pids running, one in the drive and one in lcnc
01:25 AM R2E4: Would that pose a problem?
01:28 AM archivist: if load is significant on one axis it will slow and have a following error, this needs setting small in the drive and the error going back to lcnc but that does not correct the other axes in sync without encoder feedback
01:29 AM archivist: you have to run one in torque and the other in velocity if encoder goas back to lcnc
01:29 AM R2E4: The drives are step/direction
01:30 AM R2E4: dc servos
01:30 AM R2E4: The drive should have thrown an error? You could then take that error in lcnc, no?
01:31 AM archivist: yes then it just stops
01:31 AM IchGucksLive: till later
01:32 AM archivist: position feedback means the other axes can slow in sync and not get a ferror
01:34 AM R2E4: yes but it needs to be controlled so the only way is to put lcnc into the loop.
01:35 AM R2E4: The drive needs to do it if lcnc is not informed, so the drive did not do what it was suppose to do.
01:36 AM R2E4: Did it break anything?
01:40 AM archivist: no but he did get wrecked parts
01:41 AM archivist: seems the default ferror in the drive was very large so he never got fault
01:50 AM R2E4: yes but what caused the error in the first place?
01:52 AM gloops: workpiece lifting
01:54 AM archivist: thus a larger cutting force
01:58 AM Deejay: moin
01:58 AM gloops: well, going to have a go at casting some ally plates today, and some billets for turning
02:02 AM gloops: then the building begins, should be pretty quick this time
02:03 AM R2E4: gloops: what are you casting?
02:03 AM gloops: R2 2 z axis plates, bit bigger than i have attempted before about 7lbs of ally each
02:03 AM gloops: if no good ill proceed with original steel z design
02:05 AM gloops: £80 retail, im not paying that
02:06 AM archivist: of scottish descent?
02:06 AM gloops: yorkshire lol
02:08 AM gloops: ive made a few smaller pieces, machines lovely, and very stiff
02:18 AM archivist: I remember the monty python yorkshire men sketch, you one of them?
02:22 AM gloops: we didnt have tellies in our house
02:29 AM archivist: I dont believe you :)
02:37 AM gloops: https://www.youtube.com/watch?v=IeXMKygwSco
02:39 AM archivist: cant see yt on this box at the moment
02:39 AM gloops: i will post pics of ally casting later
04:17 AM IchGucksLive: hi
04:19 AM IchGucksLive: later
05:12 AM jthornton: morning

05:31 AM MarcelineVQ: they're out of stock :(
05:31 AM archivist: if it looks to good to be true....
05:32 AM XXCoder: https://www.aliexpress.com/store/group/80-discount-cnc-kits/603041_253629563.html?
05:33 AM XXCoder: nothing aviliable so far. i was too slow aw
05:34 AM MarcelineVQ: had stuff like this one sale too https://www.aliexpress.com/store/product/Super-Closed-loop-step-motor-86HBM80-1000-servo-motor-9N-m-Nema-86-Hybird-closed-loop/603041_32833783724.html
05:34 AM gloops: yeah same here
05:35 AM gloops: just tried to order 3 packs - not available haha
05:35 AM MarcelineVQ: prob wassn't bought, probably had a new guy do a stock and he didn't understand what a 0 was
05:36 AM MarcelineVQ: so al these are "94% off!" but not on purpose
05:36 AM XXCoder: asking seller now heh
05:37 AM archivist: its the same trick as boxing day sales, only ever one or few at that price
05:37 AM XXCoder: archivist: except its everything in store
05:37 AM XXCoder: havent found non-sale so far
05:38 AM archivist: rest is 10% or similar
05:38 AM gloops: well it seems they were avaialble, missed out there
05:39 AM MarcelineVQ: oh right there was a sale event today wasn't there, these are still really suspicious prices but at least the next time ali emails me about a sale event I might want to actually have a look
05:40 AM gloops: yeah thats it irony of it Marcel, all those 'look fantastic offer' emails that nobody ever opens
05:40 AM MarcelineVQ: well like archivist said there may not have really been much stock avaialble anyway
05:41 AM XXCoder: that seller sells LOT of electrics stuff
05:41 AM XXCoder: chips and so on
05:41 AM gloops: 10 i think of each - well worth it this will be going viral now, good advertising for them
05:42 AM XXCoder: too bad, that kit'd be good for making big cnc router I always wanted to make!
05:43 AM archivist: then you check out, sorry sir only one per customer
05:46 AM gloops: well my bragain 400mm rails arrived just on time anyway, everything is here, no excuses now, and i havent even got the garage tidied back up
05:47 AM XXCoder: bad boy, messy garage heh
05:48 AM gloops: just boarded it out lol, not got everything back
05:48 AM gloops: it will happen as i build, somehow
05:48 AM XXCoder: murphys law heh'
05:49 AM gloops: well, i havent got building fever just yet, still pretty relaxed and not in a hurry, when it does kick in its amazing what can be done in a day
05:50 AM MarcelineVQ: guess it's time I learned the ali express api so I can filter items that are sold out
05:50 AM gloops: my mrs certified me as being bi-polar last time, was in garage at 6 am and not coming out till 6 pm
05:51 AM XXCoder: https://www.youtube.com/watch?v=MDGRL2GpydI
05:52 AM malcom2073: Bah, bought an item on ebay because it said it was in New York (which shouldbe 2 day ground shipping). Shipped from CA, won't be here for a week :/
05:52 AM MarcelineVQ: XXCoder: there'ssomething gross about that melt-line down the middle, what exactly is this thing?
05:52 AM XXCoder: havent finished video so far, so no idea lol
05:52 AM MarcelineVQ: I skipped to the end and it's, suggestive to say the least
05:53 AM XXCoder: from what i can figure its a fancyass drawer
05:53 AM Contract_Pilot: XX
05:54 AM MarcelineVQ: yes it is that. and it's called it the atomic box because it's got a mushroom clou-ish shape, but in a vacuum it's uhm, a little odd
05:54 AM gloops: could make a good coffin like that
05:56 AM XXCoder: fancy
05:56 AM gloops: he is using some nice equipment there though
05:56 AM XXCoder: I wonder what percent of coffins was re-buried again and again
05:57 AM gloops: or burnt
05:57 AM gloops: i cant seem them burning a £1000 coffin when they cremate someone, and the relatives dont get it back
05:57 AM XXCoder: I told my family, burn my body and pour ashes in toliet or something
05:58 AM XXCoder: or whatever cheapest option, including drive dump body off side of remote location of freeway
05:58 AM gloops: was a hells angel round here made a sidecar from one years ago - it had a 'drip tray' in the bottom
06:00 AM MarcelineVQ: full price wantai units coming back on-shelf hehe
06:09 AM XXCoder: https://www.youtube.com/watch?v=I5q8Aw2SLjM seems awesome
06:11 AM gloops: do you think household salt will have any fluxing value with alu Marcel?
06:17 AM MarcelineVQ: no clue
06:18 AM jthornton: IIRC you use lite salt
06:18 AM MarcelineVQ: people seem to use light salt thoggh
06:18 AM MarcelineVQ: hehe
06:24 AM XXCoder: Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
06:52 AM XXCoder: nice drone usage https://www.youtube.com/watch?v=LSACXadbSBA
06:56 AM JT-Shop: that's a stock quad and I have one just like it
08:33 AM * Loetmichel is getting fat... just hat to "tune" the work chair a bit... it drooped down over time... a smal angle aluminium profile and that problem is taken care of... -> http://www.cyrom.org/palbum/main.php?g2_itemId=16888&g2_imageViewsIndex=1
08:37 AM SpeedEvil: Loetmichel: you could address the causative issue too.
08:37 AM SpeedEvil: LCNC powered liposuction.
08:37 AM SpeedEvil: I'll throw in $20 for the youtube livestream of the test.
08:40 AM Loetmichel: SpeedEvil: i dont see how buying a new stronger gas cylinder will makle a good live video ;)
08:58 AM gloops: alu casting FAIL!
08:59 AM SpeedEvil: On an unrelated topic.
08:59 AM SpeedEvil: Anyone got any 11/11 related bargains they spotted?
09:00 AM gloops: from wantai? nope, all gone
09:01 AM archivist: what part of it failed
09:02 AM gloops: cannot keep that amount of alu sufficiently fluid with one torch
09:02 AM archivist: add insulation to concentrate heat
09:02 AM MarcelineVQ: mmm, sounds like you need a thicker crucible then
09:03 AM gloops: if the pot was on a fire underneath and had the torch on top - no problem
09:03 AM gloops: basically need a realistic kiln
09:06 AM SpeedEvil: gloops: you need to construct more pylons.
09:08 AM gloops: pylons?
09:08 AM gloops: i will not attempt it again just now i cant do with distractions - just a roll of the dice before i start making a machine
09:10 AM archivist: just catalogued a book to suit, Electric melting of iron and non-ferrous metals, circa 1968
09:11 AM MarcelineVQ: gloops: you don't have additional pylons?
09:11 AM gloops: not sure what you mean by pylons? i have a pot and a flamethrower lol
09:11 AM Vitran: nope. he does not have sufficent pylons for that
09:11 AM MarcelineVQ: the cool homeshop thing for melting metal these days is induction
09:12 AM Vitran: https://www.youtube.com/watch?v=tEJd838oNp4
09:13 AM gloops: with this larger amount, i found the metal went slushy, you can get it fluid eventually but quickly turns back to slush, on pouring part of it is already slush by the time the other half is in the mold
09:13 AM Vitran: the mold must be heated too
09:13 AM Vitran: in order to get the metal to flow
09:14 AM archivist: was the metal pure, no zinc etc
09:15 AM gloops: that is something else archivist, i melted one bit of scrap that was pretty stubborn to go, maybe some kind of alloy that contributed to the overall difficulty
09:16 AM gloops: i would say it is doable on a garage/back yard basis, with the proper preparation, i was looking for a plate 16x7 inch 3/4 thick
09:17 AM SpeedEvil: The main question is - are little defects OK
09:17 AM SpeedEvil: that makes it way easier
09:17 AM MarcelineVQ: there's some mic's with good sale prices on ali atm, depending on your shipping costs and such anyway
09:18 AM SpeedEvil: gloops: also, for that size, a pie-pan may be the easy solution
09:18 AM gloops: dont want to wait really Marcel, i will go with steel for now, no compromise for rigidity, not that much for weight
09:19 AM gloops: SpeedEvil as a mold?
09:20 AM SpeedEvil: gloops: yes
09:20 AM SpeedEvil: just pour it in on some refractory surface
09:20 AM SpeedEvil: while nice and hot
09:20 AM gloops: thin metal molds arent good, they buckle
09:20 AM SpeedEvil: yes.
09:20 AM gloops: not for flat plates anyway
09:21 AM MarcelineVQ: gloops: if you're using tubing remember you can fill it with simpl stuff like sand, which is also easier to get back out again than a lot of thingsd
09:21 AM gloops: you might be able to melt the ally in the mold, with the right mold
09:22 AM SpeedEvil: gloops: A stainless steel foil lined ceramic mold might work well. Just some firebrick or similar.
09:22 AM gloops: Marcel im a bit concerned about weight really, probably without cause but will see how it goes and maybe fill later
09:22 AM SpeedEvil: But then I have a roll of stainless foil, and it's annoyingly expensive
09:22 AM gloops: for the mobile parts anyway
09:22 AM SpeedEvil: Also - just pouring it two inches thick and accepting the warping may be a solution
09:23 AM gloops: lol, quite a bit of machining to do though Speed
09:24 AM gloops: actually kiln dried sand flows very well, could fill hollow sections from drilled holes maybe
09:24 AM MarcelineVQ: well yeah, I didn't mean put the sand in before construction doh ho ho
09:24 AM MarcelineVQ: that'd be a heck of a video though
09:25 AM MarcelineVQ: mind you lead shot might be a good option for a permanent fixture
09:25 AM MarcelineVQ: you can even make if yourself by pouring into a watertub
09:26 AM gloops: ive seen people mention sand filling and though - that could be awkward, imagining someone poking damp sand in to a tube with a screwdriver or something lol
09:26 AM MarcelineVQ: you could attach a little vibrator or rubber-based sander to the frame to help the sand along on flats
09:27 AM MarcelineVQ: waht are those called, disk sanders?
09:27 AM gloops: the z axis alone is going to weigh 30lbs without spindle, im not sure filling will be required
09:27 AM MarcelineVQ: no, something else, hmm
09:27 AM gloops: random orbit?
09:27 AM MarcelineVQ: orbital, but not spinning
09:28 AM MarcelineVQ: like a mouse sander but bigger
09:28 AM gloops: anything like that would probably help it flow
09:29 AM MarcelineVQ: I'm not sure if it's weight exactly as much as it's about causing the vibration you get to be evenly affecting the frame
09:30 AM gloops: yes, although the mass alone will help there are other factors
09:30 AM gloops: building out of symmetry also helps
09:30 AM MarcelineVQ: would be a good thing to learn about, resonances
09:31 AM MarcelineVQ: not the biggest consideration for machine #1 anyway
09:31 AM gloops: its like if you throw a stone in a pond, in the centre, the ripples spread out to each corner of the pond - then return
09:31 AM gloops: when they all meet in the centre again - you get a wave
09:32 AM gloops: you need to avoid creating centres like that
09:33 AM gloops: so the ripples miss one another
09:34 AM SpeedEvil: https://www.youtube.com/watch?v=RHTcSKkUU8U - related
09:34 AM SpeedEvil: esp around 0:35
09:34 AM SpeedEvil: When your pool has way too many axes.
09:35 AM gloops: yes, some interesting experiments to be seen in wave tanks, you can cause a tidal wave with a constant drip
09:35 AM gloops: everything in the cosmos is waves
09:35 AM MarcelineVQ: SpeedEvil: mymy that's the most exceptional 'chatter' I've seen yet
09:35 AM MarcelineVQ: would bust your insert in twain
10:44 AM Contract_Pilot: Morn`n
10:46 AM gregcnc_: https://www.instagram.com/p/BbQNNnqgUWz/
10:47 AM gregcnc_: talking snow tonight
10:48 AM gregcnc_: nothing sticking around
11:05 AM gloops: long may the fine mild weather last here
11:06 AM Tom_L: soggy fall day here
11:09 AM Tom_L: gloops, http://ruemohr.org/~ircjunk/projects/smelter/slide.htm
11:11 AM Tom_L: you gotta get it hot all around
11:11 AM archivist: that outer insulating container
11:12 AM Tom_L: http://ruemohr.org/~ircjunk/projects/smelter/p1040229.jpg
11:15 AM gloops: yes that became apparent Tom, i was only applying heat from above, once you get to a depth of about an inch and a half the blower struggles to keep the bottom fluid, it turned to slushy/paste like metal, would definately work with a bit more thought
11:15 AM gloops: surprising really how much difference just a bit less heat makes in one spot
11:15 AM Tom_L: collect it
11:16 AM gloops: i dunno i might have one more go
11:16 AM Tom_L: don't give up after the first try
11:16 AM gloops: well, i will have another go definately, later on
11:16 AM Tom_L: scratch your head and do it again and again...
11:17 AM gloops: left it a bit late, everything is here to build my machine now, i didnt ought to get sidetracked with experiments heh
11:18 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/StepperMount3.jpg
11:18 AM Tom_L: i worked on a couple mounts last night
11:18 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/StepperMount2.jpg
11:18 AM gloops: must be getting lose if the motors are going on?
11:18 AM gloops: close
11:19 AM Tom_L: just fitting everything
11:19 AM gloops: thats a nice little recess
11:19 AM Tom_L: following the cad plan
11:19 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Steel11_mounts.jpg
11:19 AM gloops: plan the build, build the plan
11:19 AM Tom_L: it all has a plan
11:19 AM archivist: those couplings break sometimes, may need the Oldham type
11:20 AM Tom_L: yeah those are for the sherline
11:20 AM Tom_L: actually
11:20 AM Tom_L: just put it on as a fit test
11:20 AM gloops: i have a plan, its on a thousand bits of paper in pencil though
11:20 AM Contract_Pilot: What ya makign
11:20 AM Tom_L: sparks
11:21 AM archivist: write the plan on inside rear of skull
11:21 AM Tom_L: that's the storage backup place
11:21 AM Contract_Pilot: I i giided up on the ig the other night
11:21 AM gloops: thats what it is, a mental vision
11:21 AM Contract_Pilot: mig
11:21 AM Contract_Pilot: forgot that I had flux core in it...
11:21 AM IchGucksLive: hi
11:22 AM Contract_Pilot: forgot to change back my polaraty
11:22 AM JT-Shop: Tom_L: that is the correct coupling IMHO for a stepper
11:22 AM gloops: a 10mm steel plate 16'x7' weighs 1 stone
11:23 AM jym: gloops: Is that imperial or metric ?
11:23 AM gloops: 20mm alli same size weighs 10lb
11:23 AM archivist: JT-Shop, seen reports of them cracking is not dead in line
11:23 AM gloops: in inches jym
11:23 AM JT-Shop: I'm sure some cheap chinlee ones will break under normal use
11:24 AM gloops: apart from the thickness
11:24 AM IchGucksLive: Folks someone discoused with me the spindle orientation problem in PID mode but i cand find the log
11:25 AM gloops: <R2E4> Ichs?
11:25 AM IchGucksLive: does anybody know how recently Aug till now discused a spindle orientation M19
11:25 AM jym: gloops: inch/tones... got it ;)
11:26 AM IchGucksLive: is it posible to search the logs
11:26 AM gloops: should be able to if theres a bot for it
11:26 AM archivist: use google site search
11:28 AM IchGucksLive: archivist: how do i search a indey for motion.spindle-orient-angle
11:29 AM IchGucksLive: JT-Shop: are the day logs downloadable in a script
11:29 AM IchGucksLive: like python grap
11:30 AM Crom_: IchGucksLive: shellscript loaded by at or cron
11:32 AM JT-Shop: IchGucksLive: you would have to ask Tom_L or archivist
11:32 AM archivist: IchGucksLive, https://blog.hubspot.com/marketing/how-to-do-a-google-site-search
11:33 AM archivist: I have not created a search box for my log
11:34 AM Crom_: export YR=`date --rfc-3339="date"| cut -d"-" -f 1`
11:34 AM archivist: mainly because it is a mixed log of all channels
11:35 AM Crom_: Time to put on a cuppa
11:36 AM IchGucksLive: this does not work http://tom-itx.no-ip.biz:81/~tom-itx/irc/logs/%23linuxcnc/index.html%20motion.spindle-orient-angle
11:36 AM gregcnc_: http://tom-itx.no-ip.biz:81/~tom-itx/irc/logs/%23linuxcnc/index.html
11:37 AM archivist: dont make up syntax
11:37 AM IchGucksLive: ok no problem i will find it
11:43 AM IchGucksLive: got it
11:43 AM IchGucksLive: 25augest
11:43 AM Deejay: what?
11:44 AM IchGucksLive: the M19 discussion
11:45 AM IchGucksLive: Tom_L: are you on
11:45 AM IchGucksLive: he got the problem and solved it
11:46 AM Loetmichel: re from work... maaan... "only a bit tinkering on the new printer so that the frelance Engineer can measure it!"... full 8 hour day :-(
11:47 AM JT-Shop: archivist: I don't think you can google search toms pages but I might be wrong...
11:48 AM * JT-Shop wanders inside for a nap
11:49 AM Tom_L: IchGucksLive mine aren't
11:50 AM archivist: JT-Shop, you can mine :)
11:50 AM Tom_L: bbiab
11:50 AM IchGucksLive: Tom_L: did you update the sherline ini and hal so as it is working on your mashine
11:50 AM Tom_L: not yet but i plan to
11:51 AM IchGucksLive: can yiu give me the config folder
11:51 AM IchGucksLive: as i got someone with the same problem to solve
11:56 AM IchGucksLive: Tom_L: i mean this 2 files you shuodt update http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/screenshots/
11:57 AM IchGucksLive: and if you can and will to do so put the intirer config flder there
11:58 AM IchGucksLive: as it works for you we can then put this into the lcnc wik as a startup examplei
11:58 AM IchGucksLive: Thanks
11:59 AM Crom_: 6 hours yesterday to change one water hose on the 95 honda odyssey. 8mm ID hose 150mm long. On the back side of the intake underneath
12:01 PM Crom_: I have the other hose back there to change as well, it's even worse to get to.. Thinking about taking intake apart to get access
12:03 PM Crom_: honda odyssey 95 intake plenum gasket
12:03 PM Loetmichel: Crom: just break your forearm in a few places or get an octopus rentacle grafted on instead of one arm
12:03 PM Loetmichel: makes working on modern cars a LOT easier ;)
12:03 PM Crom_: ack..
12:03 PM Loetmichel: -r+t
12:04 PM * Loetmichel used to tinker around on old military Trucks... MAAAN is that easy compared to the new car stuff
12:04 PM Loetmichel: you got a sledgehammer in between every part to do some persuasion without any effort ;)
12:07 PM Crom_: heh, working hard to get nano bots sorted
12:09 PM Crom_: you just put 24" long pieces of PVC pipe filled with steal, silicone, copper, and other feed stocks in the engine compartment, and the nanobots get what is needed to keep the engine, joints, and electrical components up
12:11 PM Crom_: Or you set up your garage to support them. When you park the car in the garage, they fix everything that needs fixing every night
12:12 PM TurBoss: Hello
12:12 PM TurBoss: what are a good kinematics to start a robot arm?
12:12 PM TurBoss: no scara
12:12 PM Crom_: Turboss, polar
12:12 PM TurBoss: Ohhh
12:12 PM TurBoss: checking ty
12:12 PM Loetmichel: Crom: problem with nanobots is that they are a) not invented yet) and b) will have slight computing power issues when they are
12:13 PM Loetmichel: to do complex tasks like recognizing macroscopic wear
12:13 PM Loetmichel: TurBoss: delta with six motors could also be fun ;)
12:14 PM TurBoss: it must be cheap + easy
12:14 PM TurBoss: :D
12:14 PM Crom_: Loetmichel: which is why I think they are going to need an eviroment to support them. Like a garage with power transmitters, additional computing power/ controller... Read Travis "Doc" Taylor's Warp Speed series.
12:15 PM Tom_L: IchGucksLive, i tested those and got it somewhat working
12:15 PM Tom_L: i don't plan to keep that as part of the config though
12:16 PM Tom_L: i can post the configs though if you want
12:16 PM Crom_: wow nickserv was really slow today
12:17 PM Tom_L: it's the weekend what do expect?
12:17 PM IchGucksLive: Tom_L: please do so
12:17 PM Crom_: true, I forget other people have to work
12:17 PM Tom_L: i found andy's work to be sufficient though
12:20 PM Tom_L: IchGucksLive, pretty sure my configs are up there already though
12:21 PM IchGucksLive: from the AUG 28
12:22 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/sherline/
12:22 PM IchGucksLive: THANK YOU
12:23 PM Tom_L: i may add a couple files here so just a sec
12:23 PM Contract_Pilot: I had 2 sherlines at one time
12:23 PM IchGucksLive: i try to get money for 6 of them to the university
12:24 PM IchGucksLive: as a mechatronics Student experimental work
12:25 PM Tom_L: that should be most of it
12:26 PM Tom_L: if my brain sits idle too long, i forget what i did
12:27 PM Tom_L: the stock sherline motor really isn't suitable for orient though
12:27 PM Tom_L: this was more an exercise to see if i could get it to work
12:28 PM IchGucksLive: tom therehas been also a remap of M6
12:28 PM Tom_L: hmm
12:28 PM Tom_L: what file does it point to?
12:30 PM Crom_: brb rebooting, just resized partition
12:30 PM IchGucksLive: Tom_L: a ngc file named change
12:31 PM Tom_L: iirc you can find that in the vismach demo stuff
12:31 PM IchGucksLive: is it only renamed
12:31 PM IchGucksLive: from toolchange
12:31 PM IchGucksLive: or did you modyfi all 3 files
12:32 PM IchGucksLive: REMAP=M6 modalgroup=6 prolog=change_prolog ngc=change epilog=change_epilog
12:32 PM Tom_L: i just posted it
12:32 PM IchGucksLive: ok
12:32 PM Tom_L: not much to it
12:33 PM Tom_L: calls M19
12:33 PM Tom_L: and waits for manual tool change to receive an orient signal
12:33 PM Tom_L: with a real carousel you would do that differently
12:35 PM IchGucksLive: i got it
12:35 PM IchGucksLive: its a start place
12:35 PM IchGucksLive: THANKS
12:41 PM synfinatic: hey everyone, i'm i'm a newbie when it comes to CNC/milling. I've designed parts which other people have milled for me, and I 3d print. Strongly considering starting with a manual mill and then later converting to CNC. Even though I'm pretty technical the learning curve seems pretty steep and I'd rather buy the right mill first then the wrong mill and later upgrade. I've done lots of google searches, reading on various forums, but information
12:41 PM synfinatic: seems really scattered. Are there any good single point references/resources? I feel there's a lot that I don't know I don't know.
12:42 PM MarcelineVQ: http://vintagemachinery.org/ is pretty great resource if you're buying used
12:42 PM MarcelineVQ: their publicatios section has manuals and everything
12:43 PM Tom_L: IchGucksLive feel free to repost them somewhere if you want
12:44 PM Tom_L: synfinatic everyone's needs/wants are different
12:44 PM Tom_L: somewhat depends what you plan to do with it
12:45 PM Tom_L: or have space for
12:45 PM synfinatic: yep. hence why i'm not asking "what should I buy" :)
12:45 PM Tom_L: quite a few have full size mills, i have a sherline and am working on another
12:45 PM Tom_L: scratch built
12:45 PM synfinatic: more like, hey I need to learn more about this so I can weigh the pros & cons and make a good decision for my needs
12:46 PM synfinatic: i probably won't end up with a full size Bridgeport/etc since I really don't nee something that large and my garage isn't that big
12:46 PM Tom_L: the dime a dozen routers on the web probably should be avoided
12:46 PM synfinatic: yeah, not interested in a gantry engraver
12:46 PM IchGucksLive: synfinatic: hi im in germany
12:46 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base_XAxis3.jpg
12:46 PM synfinatic: hi IchGucksLive I'm over in California :)
12:46 PM Tom_L: i'm working on that to replace my sherline
12:47 PM IchGucksLive: synfinatic: better to go selfbuild
12:47 PM Tom_L: some have built them with epoxy granite
12:47 PM IchGucksLive: synfinatic: it is quite cheep and you got wat you want
12:47 PM synfinatic: really? not that i'm totally against that, but surprised.
12:48 PM IchGucksLive: synfinatic: my youtube channel https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
12:48 PM IchGucksLive: there are makershops in CA
12:48 PM synfinatic: at least most of the self built/kit stuff i've seen doesn't seem stiff enough for doing aluminum which is mostly what i'm interested in
12:49 PM IchGucksLive: synfinatic: what part sizes are we taking
12:49 PM Tom_L: i'm hoping to do aluminum with mine
12:49 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Steel9.jpg
12:49 PM Tom_L: it's still a pile of steel right now
12:50 PM IchGucksLive: synfinatic: most can do AL but not the mashining you want to see
12:50 PM synfinatic: so right now the largest part i've designed myself is 7x5x2" the largest part i've had a 3rd party do for me is closer to 5x8x12
12:51 PM synfinatic: https://www.synfin.net/gallery3/index.php/Duzucati/New-Motor-Bracket
12:51 PM synfinatic: 4 parts bolted together
12:51 PM IchGucksLive: synfinatic: that woudt fit a RF58
12:51 PM Tom_L: you would likely want something bigger than what i'm doing then
12:52 PM Tom_L: might consider finding a cnc with a broken control and doing a retrofit
12:52 PM synfinatic: my google-fu for RF58 is failing
12:52 PM Tom_L: if you have space for it
12:53 PM IchGucksLive: synfinatic: somthing like that http://www.werkzeug-wagner.de/artikel.php?artnr=WMD20VL&SessID=09b696b12ca5d92ab295c37cf0f839e1&&name=WEISS+METALLFR%C4SE++WMD20VL&sortiment=Artikeldaten_0912311200&&cat=3987209477&
12:53 PM IchGucksLive: and fit a hyperStepepr kit to it
12:53 PM gloops: what are you using for z axis Tom?
12:54 PM Tom_L: gloops what do you mean?
12:54 PM gloops: like box section or plates or something?
12:54 PM gloops: to make it out of
12:54 PM Tom_L: 1/2" plate aluminum
12:54 PM synfinatic: oh, that looks exactly? like what I was looking at: http://www.precisionmatthews.com/shop/pm-25mv/ basically an upgraded G0704
12:55 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Y_Axis_plate.jpg
12:55 PM Tom_L: that's for Y
12:55 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Z_Axis_plate.jpg
12:55 PM gloops: yeah alli plate is better lol
12:55 PM Tom_L: that's for Z
12:55 PM gloops: ok
12:55 PM MarcelineVQ: Tom_L: needs more holes, to reduce air resistance
12:55 PM Tom_L: i'll figure out a spindle mount as i go
12:56 PM IchGucksLive: synfinatic: https://www.paulimot.de/fraesmaschinen/
12:56 PM IchGucksLive: the SIEG SX3
12:56 PM IchGucksLive: it will take Steel
12:56 PM Tom_L: MarcelineVQ, they all go somewhere :)
12:56 PM Tom_L: i figure my table will be around 9 x 30 or thereabouts
12:57 PM IchGucksLive: synfinatic: a EL cabinet like this http://heimwerkermarkt-tretter.de/4A_cab.jpg
12:57 PM synfinatic: google translate is my friend
12:57 PM synfinatic: wow, that's pretty
12:58 PM IchGucksLive: synfinatic: and a set of motors http://stores.ebay.com/Rattmmotor?_trksid=p2047675.l2563
12:58 PM IchGucksLive: synfinatic: 4.5Nm is minimum
12:59 PM IchGucksLive: the 8Nm 1230Oz are most same price
12:59 PM synfinatic: so one thing that kinda has me ??? is that there seems to be a real negative opinion against manual mills which are metric and not inches. Even though I'm American, I really dislike inches (everything I design is in metric). going back and forth between the two seems like a PITA
12:59 PM IchGucksLive: synfinatic: if you can go go hybrid
01:00 PM IchGucksLive: synfinatic: the control will be in inch
01:00 PM Tom_L: later...
01:00 PM IchGucksLive: Tom_L: thanks
01:04 PM MarcelineVQ: IchGucksLive: what did you say the 4-pin connectors were on the 5 axis bob?
01:04 PM IchGucksLive: JST-XH-3s
01:04 PM MarcelineVQ: thank you

01:37 PM JT-Shop: we all know what you mean
01:38 PM JT-Shop: the RPi3 stopped running one night and I had to power cycle it, looking at the logs the webcam was throwing all kind of errors so I stopped using it
01:38 PM JT-Shop: did you get the cube camera?
01:39 PM CaptHindsight: MarcelineVQ: you can also buy the connector housing and pins so that you can crimp and assemble them yourself
01:39 PM CaptHindsight: https://www.ebay.com/itm/50-kits-XH2-54mm-2-3-4-5-6-7-8-pin-JST-Connector-plug-Male-Female-Crimps-DIP/142147287890

01:41 PM phipli: JT-Shop, not arrived yet - predicted around the 18th
01:41 PM phipli: if I remember
01:41 PM phipli: I'll be back in the country on the...
01:41 PM phipli: 17th?
01:41 PM phipli: I had some issues with my set up too
01:42 PM phipli: not sure if it was the ethernet cable or the webcam
01:42 PM phipli: I'm testing it in the sitting room atm - pointing at the wall
01:42 PM MarcelineVQ: CaptHindsight: yes I'll probably end up doing that so​ I can use more purposeful wire colors
01:43 PM CaptHindsight: https://www.banggood.com/300mm-Stroke-Actuator-CNC-Ball-Screw-Linear-Slide-Rail-Guide-with-42-Stepper-Motor-p-1166718.html ~$80
01:43 PM JT-Shop: so far the chicken coop automation is working well without the webcam connected
01:43 PM MarcelineVQ: allthought your last link has 4 colors which is great
01:44 PM CaptHindsight: MarcelineVQ: now you know what to shop for
01:47 PM MarcelineVQ: I need about, oh, 4 of them hehe
01:49 PM CaptHindsight: Round trip accuracy 0.1-0.5mm
01:50 PM Contract_Pilot: So anyone beta testing Path Pilot 2.0
01:50 PM CaptHindsight: Contract_Pilot: check on the forums
01:51 PM CaptHindsight: it's been quiet in here on that topic for several months
01:51 PM Contract_Pilot: Yea, somone got a flash drive with it but will not post any details
01:51 PM CaptHindsight: oh sorry, 2.0, nevermind
01:52 PM CaptHindsight: waiting for the caffeine to work its magic
01:52 PM Contract_Pilot: Ahhh
01:52 PM CaptHindsight: what's new in 2.0?
01:53 PM Contract_Pilot: Hopfully a new distro
01:55 PM Contract_Pilot: i know in 1.9.13 they said somthing about new network driver
01:56 PM Contract_Pilot: for another motherboard
01:56 PM CaptHindsight: so no new GUI features just driver/kernel updates?
01:57 PM CaptHindsight: when you buy a Tormach does it come with their PC?
01:57 PM Contract_Pilot: Not sure no one is talking
01:57 PM Contract_Pilot: The gigabyte GA-H81M-HD3 is getting hard to come by
01:57 PM Contract_Pilot: You can buy theirs or make your own
01:58 PM Contract_Pilot: The Motherboards they Currently Use are:
01:58 PM Contract_Pilot: • Intel DG41AN
01:58 PM Contract_Pilot: • Intel DH61DL
01:58 PM Contract_Pilot: • Gigabyte GA-H61M-S2PV
01:58 PM Contract_Pilot: • Gigabyte GA-H81M-HD3
01:59 PM CaptHindsight: if the kernel supports your hardware
01:59 PM Contract_Pilot: But in the september updats said they have a new MB
01:59 PM Contract_Pilot: Yea, want to know because I need to build 2 boxes
02:00 PM CaptHindsight: if you want lowest latency then you'd build RTAI specifically for the CPU used
02:00 PM Contract_Pilot: Using mesa Cards
02:00 PM CaptHindsight: not sure how much work they do on the kernel building
02:01 PM Contract_Pilot: Currenly using 10.04 and totaly usless
02:01 PM Contract_Pilot: firefox is so out dated cannot even brows the wen hahaha
02:01 PM CaptHindsight: it's lots of work
02:02 PM Contract_Pilot: Kid hacke in to it in no time whn it was on the network
02:03 PM CaptHindsight: well once you connect to the net there is not much you can do
02:04 PM Contract_Pilot: http://store.gigabyte.us/refurbished-ga-h81m-hd3-intel-h81-motherboard/
02:04 PM CaptHindsight: UEFI was never built with security for you in mind, it is for security from you
02:05 PM Contract_Pilot: Had some in friday but bank was closed.... now out of stock
02:06 PM Contract_Pilot: To bad I only have 5I25's hate to have to buy all 6I25's
02:07 PM CaptHindsight: PCI vs PCIe?
02:07 PM Contract_Pilot: Yep.
02:07 PM Contract_Pilot: Can get this board http://store.gigabyte.us/refurbished-ga-h81m-s2h-intel-h81-motherboard/ just lacks the PCI slots
02:08 PM Contract_Pilot: I guess you need a board with a seperate chipset for the USB
02:09 PM Contract_Pilot: So need somthing with a PCI slot and dedicated USB controller
02:10 PM Contract_Pilot: Defets the purpose if i have to buy all new mesa cards
02:10 PM Contract_Pilot: Unless somone has 2 6I25's they want to sell
02:11 PM CaptHindsight: pretty sure Mesa has them :)
02:11 PM Contract_Pilot: Yea, but at 109ea ouch
02:12 PM Contract_Pilot: I seriously hate buying things 2 times
02:12 PM Contract_Pilot: Already have the 5i25's
02:14 PM pcw_home: almost any older PC with PCI slots should work
02:14 PM pcw_home: say core duo vintage
02:17 PM CaptHindsight: https://forum.linuxcnc.org/54-user-exchange/32835-new-cnc-mill-expert-linuxcnc-person-wanted-for-new-vmc-project nice machine frame
02:19 PM CaptHindsight: as a kit I don't see how they would ever end up square for most people
02:23 PM gregcnc_: seems like it would be tough to align as two axes would be free when you loosen the bolts on the side.
02:23 PM Contract_Pilot: Down to 177 today from 204
02:23 PM gregcnc_: glucose?
02:23 PM Contract_Pilot: Weight
02:24 PM Contract_Pilot: Doc wants me down to 155

02:26 PM Contract_Pilot: Surg 2 minor 1 on my back T2
02:27 PM gregcnc_: capt never heard of them
02:27 PM CaptHindsight: no fun, I'd ask for some lipo while they are in there :)
02:28 PM CaptHindsight: gregcnc_: I ended up on their ML somehow
02:28 PM Contract_Pilot: Wow that is small for that type of money
02:28 PM CaptHindsight: yeah
02:28 PM CaptHindsight: I have to find those customers
02:28 PM gregcnc_: schools probably
02:29 PM Contract_Pilot: The public school system is cherning suckers out everyday

02:53 PM Contract_Pilot: Happy with my Tormach
02:53 PM Contract_Pilot: Just need to get the shop remodel finished but hard to do when broken
02:54 PM Contract_Pilot: Need to build 4 PC's
02:54 PM CaptHindsight: a good machine always starts with a solid foundation https://www.youtube.com/watch?v=RR0ZreJoAI0
02:56 PM CaptHindsight: and 2 weeks later they got parts in that were 2" longer than the travel :)
02:59 PM Tom_L: that's not the mini mill i was talking about :)
03:02 PM CaptHindsight: Tom_L: how is your new mill project coming along?
03:02 PM gregcnc_: and it wasn't the office mill?
03:02 PM CaptHindsight: screws and bearings arrive yet?
03:12 PM gregcnc_: https://www.youtube.com/watch?v=cBKzh1hPcKo
03:21 PM JT-Shop: SpeedEvil: no, but I read the build log for it
03:21 PM JT-Shop: it was made from a couple of old sat dishes
03:42 PM JT-Shop: changed my LAN to 192.168.1.xxx and now my 3 Ubuntu PC's are stuck on 192.168.0.xxx
03:49 PM * JT-Shop wonders why he set a static ip on them...
03:53 PM Deejay: gn
03:54 PM SpeedEvil: JT-Shop: I have a pond made from a radome cover
03:58 PM JT-Shop: cool
04:20 PM Contract_Pilot: So wondering if i should try these Lenovo M70E they have the G41 Chipset
04:32 PM skunkworks: where?
05:01 PM Tom_L: CaptHindsight, pics to date: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/
05:02 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/StepperMount2.jpg
05:02 PM Tom_L: made the mounts last night
05:03 PM Tom_L: need one more for X
05:03 PM hazzy: Tom_L: Looking good
05:03 PM MarcelineVQ: someone flattened your welds :O
05:04 PM Tom_L: not welded yet
05:04 PM Tom_L: i need to undercut that a little
05:04 PM MarcelineVQ: oh interesting, the pattern of the light in http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/StepperMount1.jpg made it look like a fine weld that had been ground a bit
05:04 PM Tom_L: probably get screws after the holiday
05:05 PM MarcelineVQ: but I see it's just the plate end now hehe, that your diamond saw?
05:05 PM Tom_L: mixture of sharpie and burnt metal :)
05:06 PM MarcelineVQ: do you have a sand blaster?
05:06 PM Tom_L: no
05:06 PM Tom_L: da
05:06 PM Tom_L: 3
05:06 PM chopper79: Hey all
05:06 PM MarcelineVQ: that piece is just weirdly clean? :>
05:06 PM Tom_L: i'll probably de'paint all the bars eventually
05:12 PM chopper79: Does anybody know where to get replacement smoke for a 7i76e?
05:19 PM Tom_L: from the mesa smoke free store
05:20 PM chopper79: haha.... was hoping for something closer.
05:20 PM chopper79: Going through trying to figure out why it let out.
05:20 PM Tom_L: i bet it had help
05:20 PM chopper79: I am sure
05:22 PM chopper79: 5v inout by itself worked fine and lights turned on. 24v field worked by itself and led turned on for field. Shut off power plugged 5v input in and kept 24v field plugged in. Turned on and smoke on the two output IC chips with no outputs plugged in.
05:24 PM chopper79: Going through manual to see if I missed a jumper or something. Already verified that the + and - are not reversed. W1 is in left position.
05:24 PM Contract_Pilot: Humm
05:24 PM Contract_Pilot: Chopper I had hed a few people of the e's letting smoke out for noi reason
05:24 PM Tom_L: you didn't mix the field voltage with the 5v did you?
05:25 PM Contract_Pilot: had herd
05:25 PM chopper79: field voltage is 23.87vdc and 5v supply measured 4.96vdc for the 5v supply side.
05:26 PM chopper79: no field and 5v input are not mixed and they operated fine on their respective inputs one at a time.
05:26 PM Contract_Pilot: Marcel i have a sand blaster http://www.stevenrhine.com/wp-content/uploads/2017/06/image-1-1024x768.jpeg
05:27 PM chopper79: Left field connected and plugged 5v connector in and smoke show
05:28 PM Tom_L: i'd ask pcw_home about it
05:28 PM chopper79: Contract_Pilot: I have done a few measa setups and they always went about 98% smooth. Only burnt one 7i77 up by my doing. Rest of the builds I have done went well.
05:28 PM chopper79: besides this one....haha
05:30 PM Contract_Pilot: Yea, as soon as i can order a tormach board i am going to dump my other 7I76
05:30 PM Contract_Pilot: but right now i am stuck with a 7I76 and 7I77 i am not going to use
05:30 PM Tom_L: 77 is servo right?
05:31 PM Tom_L: 76 stepper
05:31 PM Tom_L: ?
05:31 PM chopper79: yes
05:32 PM Tom_L: wonder what i should work on next...
05:32 PM Contract_Pilot: 'Yep.
05:32 PM Tom_L: i'm thinkin a nap may be in order then stay up til who knows when
05:33 PM Tom_L: almost to the point i need rails and screws but i'm gonna wait til after the holiday to order
05:36 PM pcw_home: chopper79 : would check the field power carefully for over voltage/surges when turning on/off
05:36 PM pcw_home: (especially since 2 driver chips failed)
05:38 PM chopper79: pcw_home: The first one U5 went first and then U4 right after. Do those control the outputs of the 7i76e?
05:40 PM pcw_home: yes
05:43 PM chopper79: pcw_home: Just checked voltages on both 5v supply and field supply. While turning them off and one I get no spikes that I can see and the voltage is stable right after turn on.
05:43 PM chopper79: even rapid cycled them and no spikes or increase of voltage at all
05:46 PM pcw_home: This is not really related to 5V (unless theres a mis-connect somewhere) since the output chips have no 5V connections
05:46 PM chopper79: What is puzzling to me is that fact that the field LED came on and Iet everything stay on for about 1min. No issue at all. Turned everything off and plugged in the 5v connector (does have ~ 5v) and that is when everything burnt up when I turned power back on
05:46 PM pcw_home: even a millisecond > 40V will kill the output chips
05:47 PM chopper79: Ok
05:48 PM pcw_home: Yeah I could see on chip going randomly but 2 suggests some kind of trouble. In any case I can issue a RMA and repair/replace the card
05:48 PM chopper79: Using regulated supplies (24vdc) Could they spike that high?
05:49 PM pcw_home: certainly shouldn't
05:49 PM chopper79: I will need to buy a new one and overnight it as I have to be testing this build by Tuesday night.
05:50 PM chopper79: Already behind the 8 ball by a week and a half. No time to have repaired and returned. Also no time for another issue either. ...... puzzled
05:50 PM pcw_home: ok but in any case ask for a RMA and return the card for analysis/repair/replace
05:51 PM pcw_home: bbl
05:51 PM chopper79: I will ...thanks
05:54 PM Contract_Pilot: pcw home you with mesa?
05:57 PM Roguish: Contract_Pilot: pcw is Mesa
05:57 PM Roguish: he's the man.
05:57 PM Roguish: knows his shit
05:57 PM Contract_Pilot: Ahhhh
05:58 PM Roguish: and a really nice guy
06:01 PM chopper79: pcw_home: This may be a very stupid idea, but I plugged the 7i76e back in and it did not smoke anymore. The field LED came on and the 5v section apears fine. Since I am only using 2 outputs from the 7i76e (besides spindle output to vfd which is not hooked up right now) could I use it still to get programming and make some headway on everything while I wait for the new board to show up? I plugged all the inouts in as well and nothing seemed to be wrong.
06:02 PM chopper79: Minus the current crusty melted chips ;)
06:04 PM Contract_Pilot: chopper i think he stepped away
06:11 PM chopper79: yeah he did.... left it there so when he comes back he can read my potentially poor idea
06:14 PM gregcnc: dang what happened, burned up
06:16 PM Contract_Pilot: only issue i ever had was when i lost power came back on wanted to reflash 5I25 faild
06:16 PM Contract_Pilot: installed in another PC took the flash
06:17 PM Contract_Pilot: flawless ever sice
06:17 PM Contract_Pilot: Sucks it looks like i may have to buy 6I25's now.
06:20 PM chopper79: gregcnc: yeah my 7i76e smoked durning testing. I took a gamble and did drop a spare 7i76 only in and everything fired up no issue. I do not have a 5i25 to run it but at least the 7i76 did not bun up. This kinda rules out the power supplies I woud think and wiring.
06:22 PM chopper79: ***double checked all wiring and manually triggered all inouts and outputs to make sure voltages and signals were ok before hooking up spare 7i76 (no E) board ***
06:56 PM sadisticroot is now known as evilroot
06:57 PM * evilroot yawns
06:57 PM evilroot: Blah
06:58 PM * evilroot wishes his office had 3-phase
06:58 PM * hazzy wishes the same
06:59 PM MarcelineVQ: https://www.youtube.com/watch?v=u229h7NcMxk :>
07:03 PM evilroot: I have a massive AC motor driver but can't use it, heh
07:04 PM evilroot: 5.5kW spindle would be dope
07:11 PM hazzy: if you have a machine that can make use of it ....
07:15 PM * hazzy goes off to get some wood and start a fire
07:36 PM SpeedEvil: https://www.youtube.com/watch?v=peDTc88K3Us on being really, really good with cranes.
07:46 PM Tom_L: that looks like one that's been fired
07:48 PM Tom_L: btw, how would you apply for such a position?
07:48 PM Tom_L: awww sure i can lift that thing... just watch
07:59 PM Tom_L: what's up pete
08:01 PM SpeedEvil: Tom_L: yeah - it's the launch of last week
08:02 PM SpeedEvil: That got a little too toasty on landing due perhaps to a leaking kerosene valve
08:02 PM BeachBumPete: Hey Tom
