12:46 AM IchGucksLive: Morning from Germany
12:50 AM IchGucksLive: gector, still online
12:50 AM gector: Guten abend from oregon
12:50 AM IchGucksLive: hi
12:50 AM gector: yeah I left IRC up
12:50 AM IchGucksLive: the input pins usaly work on Ground level
12:50 AM IchGucksLive: gector, im the person that runs this YT https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
12:51 AM gector: Thank you very much, but I already got probe-in figured out
12:51 AM gector: and I'm now messing with software that hasn't been updated in 6 years :(
12:51 AM IchGucksLive: did all the firerworkes gone of
12:51 AM gector: I suspect there are a few going off, it's only 10:51pm
12:51 AM gector: I'll go check ;)
12:52 AM IchGucksLive: oregon is corn fieldarea is it maenshight
12:52 AM IchGucksLive: her we got rain all night
12:53 AM IchGucksLive: gector, in germany firerwork is only alowed to 10pm not past
12:54 AM gector: shame, there's still spattering of them going off outside
12:54 AM gector: we live on a hill so we've got a pretty good view :D
12:54 AM IchGucksLive: gector, if you are still on 10.04 leve it ists a best to be
12:54 AM IchGucksLive: go outside celebrate the 4th
12:55 AM gector: heh, not much I could do to celebrate. We didn't buy any fireworks this year, we like to just watch
12:58 AM IchGucksLive: im off till later Bye
01:52 AM Deejay: moin
02:51 AM gloops: 9am and its red hot already
02:59 AM XXCoder: "yay"
02:59 AM XXCoder: not bad here, peqaks at mid 70s f
02:59 AM XXCoder: peaks
05:06 AM Tom_L: morning
05:12 AM Wolf__: morning
05:14 AM Wolf__: work and tool holding costs too much (or I need to stop ordering stuff) lol
05:14 AM Loetmichel: XXCoder: it peaked at 27°C this morning at home (07:30)... outside in the shadow
05:19 AM Wolf__: broke down and ordered a mini pallet from nycnc, time + material costs didn’t add up doing one on my manual mill
05:21 AM Wolf__: now to hold stuff to it, anyone use mite bites https://www.zoro.com/mitee-bite-products-inc-fixture-clamps-cam-action-14-20-pk10-10204/i/G9326003/
05:29 AM enleth: Wolf__: doesn't John have his own version of those too?
05:29 AM RyanS: is it a bad idea to run control electronics and steppers off the same transformer ( with dual rectifiers)?
05:29 AM Wolf__: no, only stuff for the vise thing he sells
05:30 AM Wolf__: not for the 1/4-20 pallet
05:30 AM RyanS: 70V and 5V
05:30 AM enleth: Wolf__: ah, so I guess he only had a video of making some of his own
05:31 AM Wolf__: $54 for x10 makes diy silly imo
05:31 AM rmu: RyanS: that doesn't make sense, get a SMPS for 5V, meanwell or similar, should only be about 3-4 beer-equivalent
05:32 AM Wolf__: even better get a 12v/5v supply to feed all the control stuff
05:33 AM enleth: rmu: the motor I was talking about yesterday: https://i.imgur.com/MhuX6Ei.jpg
05:34 AM enleth: I haven't seen them in person but the friend who has them and took one apart described the internals in a way that suggests there's a built-in resolver
05:35 AM enleth: so I guess I'll try to figure out of STMBL can handle that resolver
05:35 AM enleth: *if
05:37 AM RyanS: https://www.ebay.com/itm/70Vdc-14A-peak-25A-1000W-5V-Servo-Motor-Power-Supply-AnTek-PS-10N70R5-/372051505720?hash=item569fff7238 silly to ship this when I can get components locally. I'm seeing 2x 1000uF caps. would the transformer be 50V (*1.4 = 70V) 1000VA?
05:38 AM enleth: RyanS: the 5V part of this is not an SMPS
05:40 AM enleth: rmu: oh, actually the part number suggests this thing has a "multi-turn high-resolution encoder"
05:41 AM RyanS: no I'm just using 70V transformer psu for steppers. similar price to 4 shitty switchers of dubious origin
05:46 AM IchGucksLive: hi all rain outside
05:52 AM RyanS: those 8Nm steppers are huge would HSS57 2Nm do for the torch lifter?
05:53 AM Wolf__: 8nm? how big of a gantry are you planning? sounds oversized kinda
05:54 AM RyanS: since closed loop has 2 x the acceleration anyway
05:55 AM RyanS: i'm thinking 4Nm closed loop
05:56 AM RyanS: strangely the 4Nm and 8nm are both 6A
05:58 AM IchGucksLive: RyanS, only the Driver is 6A
05:58 AM IchGucksLive: RyanS, th stepper needs 4A
05:58 AM RyanS: the 8nm?
05:58 AM IchGucksLive: the 8Nm 6A
05:59 AM IchGucksLive: RyanS, yoiu can run 2x 4Nm HSS57
05:59 AM IchGucksLive: on one psu
05:59 AM IchGucksLive: RyanS, the 2Nm is good for torch
05:59 AM IchGucksLive: RyanS, use SFU1605
06:00 AM IchGucksLive: or the simple 1204
06:00 AM RyanS: I've seen a 4Nm hss86 but not hss57 package
06:00 AM Wolf__: THC you think needs 2Nm?
06:01 AM IchGucksLive: Wolf__, no but this is the lowest Closed you can get
06:01 AM Wolf__: ooh
06:04 AM Wolf__: that sounds overkill as well, closed loop for the THC?
06:04 AM RyanS: is the real hbs86 an older Leadshine?
06:07 AM IchGucksLive: RyanS, all is leadshine OME
06:07 AM IchGucksLive: OEM
06:08 AM IchGucksLive: RyanS, https://www.ebay.com.au/itm/2-3-4-5-8-5-12N-m-HSS86-HBS57-Hybrid-Driver-Servo-Stepper-Motor-Closed-Loop-Line/292547986414
06:08 AM RyanS: the Rattm motor one?
06:08 AM IchGucksLive: 130AU$
06:08 AM IchGucksLive: HBS57
06:09 AM RyanS: would 4Nm work without a gearbox?
06:09 AM IchGucksLive: yes
06:09 AM IchGucksLive: you are on a plasma
06:09 AM IchGucksLive: so it is only moving
06:10 AM IchGucksLive: on a good build even 2Nm may do itr
06:10 AM selroc: hello IchGucksLive
06:11 AM IchGucksLive: hi
06:12 AM selroc: I am ponderating about getting a used cnc to customize
06:12 AM RyanS: it would be good to cover the whole hypertherm range ( up to 9m/min)
06:12 AM IchGucksLive: RyanS, i dont think ypoiu can get it there
06:12 AM IchGucksLive: RyanS, this is on Welding Steel 1mm Coold down to 2DegC
06:13 AM IchGucksLive: flaten out
06:13 AM IchGucksLive: i dident make it over 5m/min on vutting with a good resault
06:13 AM IchGucksLive: RyanS, the air outblow is then so hard that you need hours to get it of
06:14 AM IchGucksLive: RyanS, while at 3.8m/min hard hit the plat to the floor and you got a razor sharp edge
06:14 AM IchGucksLive: clean plate
06:14 AM IchGucksLive: selroc, VMC ?
06:15 AM IchGucksLive: RyanS, seams you are stock in the construction loop
06:15 AM IchGucksLive: RyanS, th Mashine Hardware is the main Factor
06:16 AM IchGucksLive: if you push the Bar with the litle finger of a 1year old and it runs the whole way you are done at 1Nm
06:16 AM selroc: ??
06:16 AM IchGucksLive: if you pull as a 50year Forest worker to get it moving you are at 12Nm
06:17 AM IchGucksLive: selroc, the remake
06:17 AM selroc: don't know
06:17 AM IchGucksLive: selroc, yesterdays work
06:17 AM IchGucksLive: https://www.youtube.com/watch?v=bd3UCLH1YuM&feature=youtu.be
06:18 AM IchGucksLive: RyanS, by the way this is 4m/min at 3Nm
06:18 AM IchGucksLive: RyanS, in this video at 0,01 Accuracy
06:19 AM IchGucksLive: RyanS, conventionell
06:19 AM IchGucksLive: low cost
06:20 AM IchGucksLive: complete mashine as it is shown including all 1870.-Euros
06:20 AM IchGucksLive: the 4th axis is not build yet
06:20 AM IchGucksLive: calculated costs are 2100
06:20 AM IchGucksLive: but they got lots of parts cheeper
06:21 AM IchGucksLive: THe Spindle for instand is now 260 Euros insted of calculated 320
06:21 AM RyanS: I'll design around nema 34 and see what I can get the gantry weight down to. I suspect 2nm 23 is ok for the torch
06:22 AM IchGucksLive: yes
06:22 AM Wolf__: overkill
06:22 AM IchGucksLive: RyanS, you can get one 2Nm as you need it already and test the Y as it moves your need
06:22 AM Wolf__: 2nm will break a 3/8 end mill off on a small mill
06:22 AM selroc: IchGucksLive, interesting, but my spindle weights 27 kg
06:23 AM IchGucksLive: selroc, on refit go closed loop anyway
06:23 AM IchGucksLive: selroc, getting cheeper and cheeper
06:24 AM IchGucksLive: Wolf__, it is nearly the same price as a standard combinatin
06:24 AM IchGucksLive: Wolf__, i fully agry i stay on conventionell
06:24 AM IchGucksLive: Wolf__, on plasma you deal with EMI so closed loop get a real benefit
06:24 AM Wolf__: I have all my parts on hand except mesa card and THCad
06:25 AM IchGucksLive: Wolf__, why mesa
06:25 AM IchGucksLive: 5Axis BOB and ground is ok
06:25 AM Wolf__: doing ethernet
06:25 AM IchGucksLive: 10 USD
06:25 AM IchGucksLive: ok
06:25 AM Wolf__: but I have a bob already
06:26 AM enleth: nothing wrong with supporting Mesa if you can afford it
06:26 AM RyanS: the hypertherm manual has 7890mm/m as best quality ( not max) for 2mm aluminium so I want to aim for that
06:26 AM IchGucksLive: enleth, agree if your budget takes it go for
06:26 AM IchGucksLive: RyanS, you will see 12m/min
06:27 AM IchGucksLive: RyanS, as we all reatch that at plasma
06:27 AM IchGucksLive: the mashine
06:27 AM IchGucksLive: not my hypertherm45
06:27 AM IchGucksLive: i got max at 4m/min
06:28 AM IchGucksLive: Watertable
06:28 AM RyanS: at 45amp?
06:28 AM IchGucksLive: 42
06:28 AM Wolf__: I’ll be running a 60A machine, but my minimum thickness is around 5mm
06:28 AM IchGucksLive: on max it jitters the airflow
06:29 AM RyanS: does the manual overestimate?
06:29 AM IchGucksLive: yes
06:30 AM IchGucksLive: under full test conditions
06:30 AM IchGucksLive: meaninfg tuned Torches
06:30 AM IchGucksLive: best elektrodes frech every 10meters
06:30 AM IchGucksLive: i go 200meters per electrode
06:31 AM IchGucksLive: RyanS, and ofcause they cheet wherever they can
06:31 AM RyanS: maybe the XP has improved I don't know if the automatic pressure regulation help
06:32 AM IchGucksLive: the new elektrodes they provide with the torch are 400% the replacments
06:33 AM RyanS: which electrodes get 200m?
06:33 AM IchGucksLive: RyanS, even the oldest hypertherm from 2005 got the regulator
06:33 AM Wolf__: I think the new one changes the pressure with the arc voltage
06:34 AM RyanS: it does
06:34 AM IchGucksLive: Wolf__, then you are in trouble with thcad
06:34 AM IchGucksLive: as the systems work against etch other
06:34 AM Wolf__: I have a hyper them1000
06:34 AM Wolf__: old box
06:35 AM IchGucksLive: i only use S-cutter for my newer mashines
06:35 AM IchGucksLive: 400Euros and same then hyper
06:36 AM IchGucksLive: also european standard plugs so torch replacment is only 50 Euros
06:36 AM RyanS: you can still manually set the pressure
06:37 AM IchGucksLive: http://www.stamos-welding.com/stamospower
06:38 AM Wolf__: I got mine when the powermax1000 was a new thing… so its almost 20yrs now? wait that cant be right…
06:38 AM RyanS: are you saying the original tips are different to the replacements?
06:38 AM IchGucksLive: https://www.expondo.de/plasmaschneider/
06:39 AM IchGucksLive: RyanS, YES they are
06:39 AM IchGucksLive: RyanS, and you cand get the original from somwhere
06:40 AM RyanS: I have the replacement tips, look identical, doesn't make sense
06:40 AM IchGucksLive: the material sams to be not the same
06:41 AM IchGucksLive: i need to change waterpipes im off this discussion.
06:47 AM gloops: curious thing, old generator been left outside - engine full of water, just drained it and cleaned the carb, got it firing up lovely - soon as exhaust is put on - wont run
07:03 AM JT-Mobile: morning
07:40 AM Loetmichel: gloops_ exhaust got a mouse nest maybe somewhere?
07:47 AM gloops: Loetmichel it seems clear, i think i found the problem in the carb now anyway
07:47 AM gloops: i just epoxied it lol
07:48 AM gloops: small plastic float - hinged on a pin as usual
07:48 AM gloops: the plastic bracket holding the pin - one hinge was cracked
07:50 AM gloops: not sure why replacing the exhaust caused it to stop, maybe coincidence
10:10 AM Loetmichel: hmm... anyone ever gave parts to a powder coater that had delrin parts on them? i have to make some "plugs" to prevent Dsub holes in aluminium parts from getting covered in paint/powder... does POM survive the 200++°C from the powder oven?
10:21 AM rmu: Loetmichel: there are powders that only need 160°C or so
10:22 AM Loetmichel: IIRC the powder coater we usualy take uses a 220°C setting on his oven
10:28 AM rmu: Loetmichel: ask them how to cover the holes, they should know. also, preprocesisng liquids need to drain etc...
10:29 AM rmu: mylar film should take the temperature. POM i suspect not.
10:30 AM rmu: you could make plugs out of PET soda bottles ;)
10:35 AM Rab: Vinyl caps are widely used for powder coat masking. Here are some other material options: https://www.stockcap.com/store/powder-coating.html
10:36 AM Rab: Actually that page contradicts me, saying standard vinyl is not recommended.
10:37 AM Rab: But maybe a chunk of silicone rubber would work.
10:38 AM Rab: In fact, a piece of soft tubing of the right diameter might conform to the dsub cutout.
10:54 AM gloops: butyl may
10:55 AM SpeedEvil: Billies brother.
10:56 AM gloops: like what car tyres are made from
10:56 AM SpeedEvil: high temp silicone sealant is cheap
10:56 AM gloops: get it in roll form, for roofing, pond liners etc
10:56 AM gloops: id imagine its a higher melting temp than vinyl
10:59 AM flyback: gloops, they sell rebuilt kits for most carbs
10:59 AM fragalot: even for trabants :P
10:59 AM flyback: oh you are in spain I think
10:59 AM flyback: your economy tanked
11:00 AM flyback: glue may be better
11:00 AM flyback: :P
11:00 AM flyback: actually it's been many yrs since spain bent over for terrorists by electing a anti war socialist after an attack, hoping al quida would leave them alone
11:00 AM flyback: and he tanked their economy
11:01 AM flyback: I like saving money fixing stuff but I have learned after many yrs some things are better just replaced or retrofitted
11:02 AM gloops: flyback it may come to that, ive got it running again but its only ticking over - any revs it dies
11:03 AM gloops: im guessing some water is still finding its way into the fuel, got the tank off now
11:03 AM flyback: or the carb has leaks
11:03 AM gloops: air leaks?
11:03 AM flyback: like the bearings are shot and leaking air
11:03 AM flyback: yeah I geuss the float hinges etc sometimes get so worn out and loose they leak air thru them
11:03 AM gloops: that would cause it rev up wouldnt it?
11:03 AM fragalot: or the needle valve is clogged
11:03 AM flyback: no
11:03 AM flyback: too much air is a bad thing
11:04 AM gloops: well, ill clean the tank out and the carb again, thats the water theory eliminated anyway
11:04 AM * flyback bites ty2u
11:04 AM flyback: CANUCK
11:04 AM flyback: gloops, is this a tractor or something?
11:04 AM gloops: its an old generator
11:04 AM flyback: ooo cool those are always worth fixing up :)
11:04 AM gloops: it ran like a dream this morning for about 5 minutes
11:05 AM flyback: wait
11:05 AM flyback: it'ds not a 2 stroke is it?
11:05 AM gloops: yes
11:05 AM flyback: did you mix in oil?
11:05 AM gloops: oh no
11:05 AM gloops: no its four stroke
11:05 AM flyback: good :) cause 5 mins would be about right for it to shit itself :)
11:05 AM flyback: without oil
11:05 AM gloops: have had rocker cover off to see valve springs were ok
11:05 AM flyback: be sure to use stabil in it
11:06 AM gloops: its 99% either fuel or air
11:06 AM flyback: or whatever the local company sells
11:06 AM gloops: as it was full of water im thinking fuel
11:06 AM flyback: if your gasoline has a lot of ethanol in it
11:06 AM flyback: there's a bacteria that eats it
11:06 AM flyback: poops vinegar
11:06 AM flyback: which eats the hell out of alum engine parts
11:06 AM flyback: it froze my float valve on my generator
11:06 AM gloops: its new juice, but i didnt clean the tank out, i can see some jelly like shit in it
11:07 AM flyback: so now I use stabil with ethanol preventative in it
11:07 AM flyback: you can keep fuel for over a year won't go bad or acidic
11:07 AM gloops: its probably a blob of water/crap getting sucked to a needle valve
11:09 AM fragalot: flyback: or you could buy special fuel with a few decade long shelf life for a mere €4/L
11:09 AM fragalot: aspen fuel, I think it's called
11:10 AM flyback: they don't have that around here
11:10 AM flyback: oh you mean avation fuel?
11:10 AM fragalot: no
11:11 AM fragalot: it's basically alkylate petrol
11:11 AM fragalot: whatever that means
11:12 AM gloops: i might have altered the float height gluing that hinge, but looks perfecly aligned to me, theres no adjusting it
11:12 AM gloops: bowl is full every time i empty it anyway
11:12 AM flyback: I got a 4 stroke gen cause you can mod them to run on propane and natural gas
11:12 AM fragalot: gloops: typically adjusting it involves bending it :P
11:12 AM gloops: plastic
11:13 AM fragalot: Well then.
11:14 AM rmu: i know aspen as special 2-stroke fuel for chainsaws
11:14 AM fragalot: yeah they have 2 or 4stroke
11:15 AM gloops: i could force the spring to be a but shorter, but i dont think ill do anything like that yet
11:15 AM rmu: uses rapeseed oil or something so you don't contaminate your forest
11:19 AM flyback: gloops, there's a lot of videos etc about fixing generators etc
11:22 AM jesseg: hmmm you guys are reminding me of something. I vaguely remember having to adjust the float angle on an all-plastic carburetor and I think I shimmed it with pop can aluminum or something, don't remember any details though, except that I suspected the plastic carb housing had swelled due to alcohol in the gasoline
11:41 AM fragalot: gloops: https://imgur.com/gallery/MqT0z0l
11:53 AM IchGucksLive: hi all
11:53 AM roycroft: so has anyone in the states noticed prices of imported machining gear going up yet?
11:53 AM roycroft: some of the websites are talking about 20% across the board price increases coming soon
11:53 AM IchGucksLive: Roedy, prices always go up
11:54 AM IchGucksLive: roycroft,
11:54 AM IchGucksLive: roycroft, nomater if trump or not
11:54 AM fragalot: 20% is al trump.
11:54 AM IchGucksLive: 4th july is pay day
11:55 AM IchGucksLive: its on Every note marked
11:56 AM roycroft: yes, the 20% is all trump
11:56 AM roycroft: it's because of the 25% tariffs he's imposed
11:56 AM roycroft: so he can create a few hundred jobs, will killing hundreds of thousands of jobs
11:56 AM fragalot: roycroft: that's a different statistic though
11:56 AM roycroft: i haven't seen any price inreases yet
11:57 AM Beachbumpete1: there must be a keystroke to toggle isometric in draftsight but damn if I can find one....
11:57 AM roycroft: but i am starting to see warnings that they're coming
11:57 AM IchGucksLive: roycroft, he might think the oposit
11:57 AM roycroft: of course he thinks the opposite - he's an idiot
11:57 AM roycroft: but that's not what i brought this up
11:57 AM roycroft: i'm actually just looking for real examples of the price increases
11:58 AM roycroft: i'm weighing prices increases against the cost of interest if i finance some stuff before they go up
11:58 AM roycroft: and trying to figure out when to expect the actual price increases
11:59 AM Rab: I heard that LittleMachineShop plans to increase prices: https://littlemachineshop.com/
11:59 AM IchGucksLive: Beachbumpete1, tools option advance
11:59 AM roycroft: yes, they're one of the sources who claim to be raising prices
11:59 AM roycroft: but they've not done it yet
11:59 AM IchGucksLive: as long as rattmotor doesend do it its ok
11:59 AM fragalot: lol
11:59 AM IchGucksLive: stepperonline now got worldwide stores
11:59 AM Beachbumpete1: there is no tools options advance
12:00 PM roycroft: my local steel yard are pretty sure they're going to have to increase prices
12:00 PM roycroft: but again, they've not done it yet
12:00 PM fragalot: they may still have sufficient stock that they bought at reasonable prices
12:00 PM fragalot: and won't increase until they need to import more
12:00 PM IchGucksLive: Beachbumpete1, tools options aliases
12:01 PM Beachbumpete1: IchGucksLive are you pulling my leg man?
12:01 PM IchGucksLive: TOOLS>OPTIONS>UserPreferences>ALIASES
12:02 PM IchGucksLive: Beachbumpete1, what version are you on
12:02 PM Beachbumpete1: DraftSight 2018 x64 SP1
12:05 PM IchGucksLive: windoes key F5
12:06 PM Beachbumpete1: yeah f5 toggles the isometric axis but is there one to turn it on and off IE move back to normal mode
12:07 PM gloops: reports show average brit will be 2.6k a year better off
12:08 PM fragalot: I don't like those generic average reports
12:08 PM fragalot: because 1% of the population can offset those dramatically
12:08 PM IchGucksLive: Beachbumpete1, you can do a user shortcut to the standard view
12:09 PM gloops: europe and america are too rich to grow, theres no future there
12:09 PM IchGucksLive: gloops, are there average bits in the world
12:09 PM gloops: sell to the poor growing countries
12:10 PM gloops: Ichs well brits arent average, but there is the average brit
12:10 PM Beachbumpete1: hmm that would be nice. never done that before
12:10 PM IchGucksLive: theyare all eting strawberrys at wimbledon
12:10 PM gloops: yes £40
12:10 PM fragalot: gloops: did you know that 50% of the british population scores below average in IQ tests?
12:10 PM IchGucksLive: sirens sounding im off Gn8
12:11 PM gloops: hope its not the russians Ichs
12:11 PM gloops: fragalot IQ is only one measure
12:12 PM rmu: *lol*
12:12 PM fragalot: gloops: well 50% of them also scores below average when it comes to critical thinking
12:12 PM gloops: very funny
12:12 PM fragalot: :-)
12:12 PM rmu: seems 50% of nearly everything is below average...
12:12 PM fragalot: rmu: give or take rounding errors
12:13 PM gloops: we'll be ok, its germany i fear for
12:13 PM rmu: and quantisation errors ;)
12:14 PM gloops: germany loaned a lot of money to zombie EU states, when the german economy tanks, the eurozone will collapse - they wont be getting paid back
12:15 PM rmu: every complicated problem has a simple answer that is wrong
12:16 PM gloops: rmu you are fighting an economic war on 3 fronts
12:17 PM rmu: i am certainly not fighting any wars
12:17 PM rmu: but these simple models that "predict" things like "every brit will be 2.6k better off" ignore the rest of the world or assume it stays the same
12:18 PM rmu: same for euro-zone
12:19 PM gloops: well, it isnt looking goog
12:19 PM rmu: but things are interconnected in strange ways, many of them hard to quantify and hard to predict
12:19 PM gloops: good
12:19 PM rmu: maybe, but it wasn't looking good 2008 either
12:20 PM gloops: you must strike a favourable deal with the UK, if your cars are on WTO with the UK AND USA, its over
12:21 PM rmu: somebody has to build those BMW convertibles british super-rich kids like to trash in the summers
12:21 PM gloops: other people make cars, we can make them ourselves
12:21 PM rmu: IMO the problem of german car industry is not that much tariffs, but they are somehow stuck in the last century
12:21 PM gloops: right
12:22 PM rmu: yeah, USA also makes cars, but why are german cars popular, it's not because they are cheaper
12:22 PM gloops: dated technology, fossil fuel engines, too big to adapt in time
12:22 PM gloops: we buy lots of fords
12:23 PM rmu: electric cars are intrinsically simple, not much things to build, not much need for hundreds of different parts of engines
12:23 PM gloops: open to production by dynamic medium sized businesses
12:23 PM fragalot: rmu: yet the issue is that they seem to want to add TOO much electronics to the electric cars..
12:24 PM fragalot: like why on earth does tesla insist on those naff door handles that need a motor & multiple microswitches to work
12:24 PM rmu: the thing with electronics is, once it is designed, the rest rolls off a production line involving next to no human labor
12:24 PM rmu: tesla is tesla, they are somewhat stupid with those things
12:25 PM rmu: i also don't get how they market their cars as "quick" when you can't really go that fast for longer distances
12:25 PM fragalot: marketing :D
12:25 PM fragalot: it doesn't have to be true as long as it's technically true
12:25 PM rmu: but then again driving in america is surely very different to driving in especially germany
12:26 PM fragalot: it is
12:26 PM fragalot: there is a reason why the catalytic converters are in different locations in USA vs EU cars
12:26 PM gloops: K1 Four Wheel High Speed Electric Car
12:26 PM gloops: FOB Price: US $ 4300.0-7800.0 / Piece
12:26 PM gloops: Min. Order: 3 Pieces
12:27 PM Rab: Isn't that true for high-performance ICE cars as well, that top speed isn't necessarily sustainable for cruising?
12:28 PM fragalot: well it is
12:28 PM fragalot: but you need new tires after 15 minutes
12:28 PM rmu: the fact is that all those trade conflict in europe around brexit only increases strength of putin and china
12:28 PM fragalot: but that's OK because your fuel only lasts 10.
12:28 PM rmu: well played distraction
12:28 PM rmu: Rab: I have no problem goind 200kph+ for as long as fuel lasts
12:29 PM fragalot: rmu: well that's the same issue electric cars have isn't it?
12:29 PM rmu: i'm talking about practical speeds at around 100-130kph
12:29 PM fragalot: they can go super quick super hard as long as fuel lasts & it doesn't overheat
12:30 PM rmu: at that speed i have a range of about 1000km, i suspect even the 100kwh teslas only go about 200-300km at 130kph
12:30 PM fragalot: probably
12:33 PM Rab: Some analysis here. Too lazy to investigate in detail, but it doesn't look like Tesla is a terrible performer in that regard: https://www.quora.com/How-long-can-you-drive-a-Tesla-S-P90D-at-maximum-speed-on-a-single-full-charge
12:34 PM rmu: strange, 155kph should not require 120kW
12:35 PM * fragalot is seeking advice
12:35 PM rmu: even my old beat-up common rail minivan with 80-ish kW did 170kph
12:35 PM fragalot: looking for an ultra wide angle lens for landscape with a full-frame Sony E mount
12:35 PM fragalot: suggestions welcome
12:36 PM fragalot: considering the Sony FE 12-24 f4.0G, or the 16-35 f4.0
12:37 PM rmu: what else do you have? i quite like the 16-35, it is my "always on" lens
12:39 PM rmu: so it seems tesla model s needs about 300Wh/km @ 160kph
12:40 PM Tom_L: fragalot, https://www.bhphotovideo.com/c/search?Ntt=wide%20angle%20cannon%20E%20mount&N=0&InitialSearch=yes&sts=ma&Top+Nav-Search=
12:40 PM fragalot: 35, 85, 24-240
12:40 PM fragalot: the 24-240 is a decent disney-lens, but the image quality is a bit meh.
12:41 PM fragalot: the 35 and 85 primes are mindbogglingly good
12:41 PM fragalot: Tom_L: Sony E, not Canon FE.
12:42 PM fragalot: And i'm not looking for a generic search result answer, but user feedback as I know quite a few people in here are enthousiasts too :-)
12:42 PM rmu: 12mm is a bit on the extreme end. i don't use the wide end of the lens much
12:42 PM Tom_L: https://www.bhphotovideo.com/c/search?Ntt=wide%20angle%20sony%20E%20mount&N=0&InitialSearch=yes&sts=ma&Top+Nav-Search=
12:43 PM Tom_L: https://www.bhphotovideo.com/c/product/1140832-REG/zeiss_2103_750_25mm_f_2_0_batis_wide.html
12:43 PM fragalot: rmu: Yeah, I'm not too convinced I need the super wide area either
12:43 PM rmu: there is a new 16.35/f2.8 ;-)
12:43 PM fragalot: is there?
12:44 PM fragalot: the GM?
12:44 PM rmu: SEL-1635GM, but about €2k5 here
12:44 PM Tom_L: https://www.bhphotovideo.com/c/product/1243591-REG/zeiss_2136_691_batis_18mm_f_2_8_lens.html
12:44 PM Tom_L: 18mm 2.8
12:44 PM rmu: and probably very heavy
12:44 PM fragalot: 2k7 here
12:44 PM fragalot: not really looking to spend more than 2k if I can avoid it
12:44 PM gloops: 4k for a 24mm - get samyang
12:45 PM Tom_L: now you're just being picky
12:45 PM fragalot: the batis is tempting
12:46 PM Tom_L: https://www.bhphotovideo.com/c/product/892389-REG/Sony_sel1018_10_18mm_F_4_0mm_Optical_SteadyShot.html
12:47 PM Tom_L: https://www.bhphotovideo.com/c/product/1039911-REG/samyang_sy8mbk28_e_8mm_f_2_8_umc_fisheye.html
12:47 PM Tom_L: wide enough?
12:47 PM fragalot: I prefer rectilinear
12:48 PM fragalot: rmu: >.> I may just go for that 16-35 F2.8GM
12:48 PM Tom_L: https://www.bhphotovideo.com/c/product/1189220-REG/zeiss_2131_999_loxia_21mm_f_2_8_lens.html
12:48 PM gloops: sigma did the rectilinear wide
12:48 PM Tom_L: 21mm
12:48 PM rmu: 680g... not that much heavier than the /4 version
12:49 PM fragalot: my other lenses aren't exactly light either
12:49 PM fragalot: with the exception of the 35 prime
12:49 PM fragalot: that thing is absolutely tiny
12:50 PM rmu: i need to take that stuff in a backpack up the mountains, so weight is a consideration
12:50 PM fragalot: I do too, but I just power through it like an idiot
12:50 PM fragalot: saving weight everywhere else, :D
12:50 PM rmu: hehe
12:50 PM rmu: sounds familiar
12:51 PM fragalot: every gram counts for the backpack, sleeping bag & mat, tent, etc... just to be able to carry the camera :D
12:51 PM rmu: 3 lenses, travel tripod, camera, replacement batteries, ...
12:51 PM Tom_L: sleep on the ground
12:51 PM rmu: the canon gear was horrible weight- and bulk-wise
12:51 PM fragalot: rmu: batteries is indeed one shitty thing with the a7rII
12:52 PM rmu: jeah, but can be mitigated a bit with a powerbank
12:52 PM fragalot: and a solar panel
12:52 PM rmu: and in-camera charging
12:52 PM rmu: solar panel makes exactly 0 sense
12:52 PM rmu: IME
12:52 PM fragalot: I use the solar panel to charge the battery bank
12:53 PM rmu: tried to kept a phone charged while doing the west highland way, no chance
12:53 PM fragalot: it depends on where you're going
12:53 PM rmu: but that solar panel needs to be HUGE
12:53 PM fragalot: i'm taking this to iceland where it's light 23.5hrs a day
12:53 PM fragalot: 20W
12:53 PM rmu: thats like a DIN A3 sheet?
12:53 PM fragalot: about the same surface as the backpack
12:54 PM rmu: 30×40cm?
12:54 PM fragalot: nearly
12:54 PM fragalot: doesn't weigh much, and allows everyone to scavenge power for their stuff
12:54 PM rmu: hmm. my panel was very small, around 100cm² at most, that was not sufficient to keep a phone charged
12:55 PM fragalot: no
12:55 PM fragalot: issue with phones is that they go "oh yeah power baby! *overclocks CPU, starts updating, ...*"
12:55 PM fragalot: so a 5 or 10W panel isn't going to do anything useful
12:56 PM fragalot: unless you have direct sunlight on it all the time
12:56 PM rmu: back then that was a symbian "smart" phone, didn't have much live on its own back then
12:56 PM rmu: and the solar panel did have its own battery pack that was charged from the sun
12:56 PM rmu: and then you could plugin the phone
12:57 PM fragalot: I had a 10W panel from goal zero,.. not incredibly useful :P
12:57 PM rmu: i think i managed half a phone-charge after one week of sun
12:57 PM fragalot: lol
12:57 PM fragalot: have you ever looked at laowa?
12:58 PM rmu: no not really
12:58 PM rmu: next thing i want to get is a really long tele-zoom
12:59 PM rmu: something in the 600mm range
12:59 PM fragalot: same
01:00 PM rmu: can't decide between tamron and sigma 150-600mm... only thing that's sure is that all those bright primes costing >10k are out ;)
01:00 PM fragalot: :D
01:01 PM fragalot: 600mm prime isn't really all THAT useful imho
01:01 PM fragalot: very limited scenarios where it will work for you I think
01:01 PM fragalot: "oh look a bird! oh.. it's too close. hang on, sit tight little buddy whilst I switch lenses!"
01:02 PM rmu: i'm a bit prone to dropping lenses and cameras, so potential damage has to be kept in check
01:02 PM rmu: hehe
01:02 PM fragalot: hehe
01:02 PM rmu: yeah, 600mm prime is not that useful
01:02 PM fragalot: in terms of dropping lenses,.. I've been using the spider holster for a few years now
01:03 PM fragalot: absolutely fantastic thing.
01:03 PM rmu: it happens mostly when preparing "for takeoff" or doing something like putting camera into backpack or taking it out
01:03 PM rmu: or forgetting to close the backpack...
01:04 PM rmu: don't want to think about it
01:04 PM fragalot: https://www.cameranu.nl/nl/p183614/spider-black-widow-holster <== other variations exist, this is the one i've got
01:04 PM fragalot: no problem climing or jumping around, camera stays nicely attached to your hip
01:04 PM rmu: will check it out
01:05 PM rmu: ok, i have to go. keep us informed what lens you get and how it performs in the midnight sun ;)
01:06 PM fragalot: I did recently get a different mounting plate for it so I can still use my tripod / monopod without having to unscrew that pin
01:06 PM fragalot: and it does hang differently compared to only the pin
01:06 PM fragalot: so i'll see if I still like it or not :P
01:06 PM fragalot: Alright! ttyl!
01:48 PM XXCoder: my room nearly 90f lol
02:03 PM gloops: yes, i hate being a heatwave bore..but its too hot
02:09 PM Loetmichel: *harhar* ex coworker called a bit earlier today:"can you help me? got a hand pump in my garden with a 1.25" rammed well under it... and the pump is 20 years old and dead... bought a new one but cant for the life of me unscrew those rustet steel threads..." ... so i went there with a 1 meter long alligator wrench and a 1 meter steel "crowbar"... set to the right points and invest a vew muscles
02:09 PM Loetmichel: and a bit rust is no problem... $me "Gewaltig ist des meisters kraft wenn er mit dem Hebel schafft!" ("mighty is the masters force if he uses a lever!") friends response: "Yes, but you have to know where to put that lever!" :-)
02:12 PM gloops: leverage, shock loading, aggression etc all good ways to free a nut
02:13 PM fragalot: or break the stud
02:13 PM fragalot: :-)
02:15 PM gloops: worst case scenario - nut in a place where a hammer cant be swung or a bar rotated
02:15 PM Loetmichel: fragalot: no way you break a 1 1/4" steel pipe or the cast iron pump base.
02:16 PM gloops: Loetmichel very short strokes with a piece of hacksaw blade - for a long time
02:16 PM Loetmichel: worst case the threaded part thats in the base shears off, then you'll have to cut a new thread in the stud and mount the pump 1" lower.
02:20 PM gloops: i think theres an overlooked factor in nut freeing as well - time
02:20 PM fragalot: sure
02:20 PM fragalot: wait longer and it gets worse
02:20 PM gloops: sometimes you just chisel and yank away at a nut with no progress for ages
02:20 PM fragalot: or wait even longer and the problem solves itself
02:20 PM gloops: then suddenly - its free
02:20 PM gloops: not doing anything different
02:20 PM XXCoder: Loetmichel: reminds me of one algbera question that was made from real life event
02:20 PM XXCoder: answer was over million ft/lb lol
02:20 PM Loetmichel: what, long lever and a tiny force to a short lever?
02:20 PM XXCoder: basically guy was trying to remove bolt from one of semi tires, and it was stuck
02:21 PM XXCoder: so he took 20 feet long pipe to it, and used his entire weight
02:21 PM XXCoder: guess what happened?
02:22 PM Loetmichel: been there, done that... we hang with 4 ppl on a 4m long pipe put on the semi nuts and had to do synchronus pullups to get it to break free...
02:22 PM XXCoder: heh nut shattered, and ruined the thread
02:22 PM XXCoder: he had to replace it, much costly job
02:22 PM Loetmichel: we sheared off the bolts
02:22 PM Loetmichel: not a big deal, they are only pressed in from the back side with fine teeth
02:23 PM Loetmichel: so after removing the wheel its just a few taps with a punch and a big hammer and you can put in new bolts into the hub
02:23 PM fragalot: yeah replacing the studs is easy
02:23 PM fragalot: Loetmichel: ... or a press. :P
02:23 PM Loetmichel: then i had to remove the hub... nope, way to much work ;)
02:24 PM XXCoder: from what I recall, that part was destroyed also
02:24 PM Rab: XXCoder, I did that with a school bus I had. Three dudes bouncing on a 6ft breaker bar. Eventually the nut started turning...and just kept turning! Then I saw the "L" stamped into the stud.
02:24 PM XXCoder: not just threads
02:24 PM Loetmichel: it was THIS truck: http://www.cyrom.org/palbum/main.php?g2_itemId=3527&g2_imageViewsIndex=1
02:24 PM XXCoder: Rab: left loosen mark ;)
02:25 PM Loetmichel: and i doubt anyone had changed the tyrs in the last 20 years ;)
02:25 PM Rab: XXCoder, yeah, "left hand thread".
02:25 PM XXCoder: lol thats even worse
02:26 PM Rab: I still have a pic: http://reboots.g-cipher.net/victim.jpg
02:26 PM XXCoder: nice and smooth
02:27 PM XXCoder: 6 feet but much more mass
02:28 PM jesseg: hey anyone know which pins on the atmega128-16ua 64 qfp
02:28 PM jesseg: are the programming pins?
02:29 PM Rab: jesseg, using ISP?
02:30 PM jesseg: Rab, I think so - I ordered this: https://www.ebay.com/itm/202255173421
02:31 PM Rab: jesseg, see pp. 300 of the datasheet: http://ww1.microchip.com/downloads/en/DeviceDoc/doc2467.pdf
02:33 PM jesseg: thanks Rab !
02:35 PM Rab: Pin 2 (MOSI), pin 3 (MISO), pin 11 (SCK), and of course pin 20 (Reset). But that's a weird gotcha with this chip, that the SPI is mapped to different pins just for programming. I haven't encountered that before.
02:36 PM Loetmichel: Rab: nice thing the stripped threads
02:36 PM Rab: I might have dropped the chip on a board with PB0-PB3 wired for ISP and wondered why it didn't work.
02:36 PM Loetmichel: happens...
02:37 PM Loetmichel: a bit smaller: http://www.cyrom.org/palbum/main.php?g2_itemId=14235 <- thats how an M3*6 phillips head screw looks when boss tries to unscrew it... ;)
02:38 PM Rab: Loetmichel, brutal
02:40 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14187 <- thats how they look right out of the box ( these are a bit shorter)
02:46 PM jesseg: Rab, thanks so much...!
02:46 PM fragalot: rmu: turns out i'm getting the 28 F.20 instead. :P
02:47 PM hazzy-lab: Whoa! Python function calls are _SLOW_. I just changed some things in gremlin to reduce function calls and it is more than twice as fast
02:51 PM fragalot: yup
03:01 PM Loetmichel: meh. sometimes i am REALLY forgetful. Third day in a row the CNC mill at the company runs thru the night... including the cooling pump for the spindle... ;)
03:45 PM Joe_Hildreth: Anyone have time for some simple I/O questions?
03:45 PM JT-Mobile: we just ask the questions here
03:46 PM Joe_Hildreth: OK, I know that _MOST_ hobbyist will use the parallel port for their cnc projects.
03:46 PM Joe_Hildreth: But, I know there are several add on cards that can be used for IO.
03:47 PM Joe_Hildreth: For an entry level user who will use steppers, what hostmot (???) cards would be suggested?
03:47 PM JT-Mobile: I would have to say a lot of first time people will want to use the parallel port to see if it really works then move on...
03:47 PM Joe_Hildreth: I am working on another CNC for the home hobbyist video and am discussing I/O options for LCNC
03:47 PM JT-Mobile: 7i76, 7i76e
03:47 PM pjm: Joe_Hildreth, hi, i started with parport then moved to 7i43 but i gather its an older card now, none the less its still awesome
03:48 PM JT-Mobile: also 7i78
03:48 PM JT-Mobile: https://mesaus.com/index.php?route=product/product&path=62&product_id=69
03:48 PM Joe_Hildreth: As I understand, some of these are PCI cards and others are Ethernet?
03:48 PM JT-Mobile: https://mesaus.com/index.php?route=product/product&path=62&product_id=53
03:49 PM JT-Mobile: yep the 7i76 and 7i78 are daughter cards and need a 5i25/6i25 or 7i92
03:49 PM JT-Mobile: the 7i92 and 7i76e are both ethernet
03:50 PM JT-Mobile: ethernet cards require LinuxCNC Uspace which is now very easy to install
03:50 PM Joe_Hildreth: JT-Mobile, Thanks for the links.
03:50 PM JT-Mobile: https://mesaus.com/index.php?route=common/home
03:51 PM JT-Mobile: check out my fancy chart on the home page :)
03:51 PM Joe_Hildreth: I am basing on the premise that the ISO will be installed.
03:51 PM Joe_Hildreth: Will do, brb
03:51 PM Roguish: JT-Mobile: nice chart...........
03:52 PM Roguish: seriously
03:52 PM Joe_Hildreth: May I use your graphic in my presentation? I will give you attribution.
03:52 PM Roguish: oh shit, links and all....
03:52 PM JT-Mobile: I'll be here for a little while then we are going to Pappadeaux for dinner
03:52 PM JT-Mobile: hey Roguish
03:52 PM JT-Mobile: Joe_Hildreth, sure all my stuff is ok to use
03:53 PM JT-Mobile: Roguish, that was actually challenging to do lol
03:53 PM JT-Mobile: we are down in Fort Worth
03:53 PM Roguish: i'm sure, since you code it by hand.
03:53 PM JT-Mobile: aye
03:53 PM Joe_Hildreth: Thank you. If your interested in what I am trying to do, a link is here: https://www.youtube.com/playlist?list=PLaamliiI72ntlrHKIFjh2VjmehRGgZpjm
03:54 PM Joe_Hildreth: Constructive criticism is welcome BTW
03:54 PM JT-Mobile: Joe_Hildreth, cool
03:56 PM Joe_Hildreth: I cannot speak for anyone else, but when I first started in this hobby, the amount of stuff to wrap my old brain around was mind boggling. I thought if I could make bit sized videos then maybe that could help someone get over the fear of starting.
03:56 PM Joe_Hildreth: Or maybe organize the madness. :-)
03:57 PM JT-Mobile: the screen shots are a bit blurred for me dunno
03:57 PM JT-Mobile: also a link to a step by step would be nice
03:57 PM JT-Mobile: I smell a new showcase...
03:58 PM JT-Mobile: if you could zoom in so the text is readable that would be great
03:58 PM Joe_Hildreth: To which part are you referring? The computer screen casts or something else?
03:58 PM JT-Mobile: 003
03:59 PM JT-Mobile: like the terminal zoom it in real big for old tired eyes
03:59 PM Joe_Hildreth: Good point. Will have to try to fugure out what tool to use to do that. Any suggestions?
04:00 PM JT-Mobile: how did you record the screen?
04:01 PM JT-Mobile: I applaud that you don't have all that crap in your videos like most do
04:01 PM Joe_Hildreth: Ubuntu desktop was recorded with SimpleScreenRecorder, the screen casts of LCNC was done with gtk Record My Desktop
04:02 PM JT-Mobile: I've not messed with them much
04:02 PM Joe_Hildreth: What crap is that? The annoying music?
04:02 PM JT-Mobile: all the self promoting and trying to be a star lol
04:03 PM Joe_Hildreth: From here out, most of the recording will be done on a Debian install of LCNC.
04:03 PM Tom_L: 7i90 is a good parallel port mesa card
04:03 PM Tom_L: better than the 7i43
04:03 PM Tom_L: cheaper too
04:03 PM JT-Mobile: you get to the point and don't dabble I like that
04:03 PM Joe_Hildreth: Oh, well, I do suggest people subscribe if they like the videos. So maybe I am guilty!
04:03 PM JT-Mobile: not in my eyes
04:04 PM Joe_Hildreth: Thanks Tom_L. I am going to copy this session to a text file so I can digest the details later.
04:04 PM JT-Mobile: see if you can figure out how to zoom to the terminal window
04:05 PM JT-Mobile: yes there are lots of 50 pin card options
04:05 PM Tom_L: jt, hot in Tx?
04:05 PM Joe_Hildreth: Truthfully, I want the videos to be about LCNC and its use. Not about me. I even remind people in every video I am not a teacher, engineer or machinist. Just another hobbyist with a mental disorder of sorts.
04:05 PM JT-Mobile: 5i24 and 6i24
04:06 PM Tom_L: and
04:06 PM Tom_L: 7i80 is a direct drop in for 7i90 if you want ethernet instead
04:06 PM JT-Mobile: Tom_L, not too bad... we went to the botanical gardens this morning and the cabin display this afternoon
04:06 PM Joe_Hildreth: Well, I don't want to overwhelm them with loads of details on all the cards available, but your link will be a great resource for them to further explore.
04:07 PM Joe_Hildreth: Also, you made the staement about needing USpace for the Ethernet cards. I have never set this up. Is there a guide or How-to?
04:08 PM JT-Mobile: https://mesaus.com/info/debian-9-uspace.txt
04:08 PM JT-Mobile: step by step
04:09 PM JT-Mobile: tested in the Beer Cave several times lol
04:10 PM JT-Mobile: the development version has some important features like gantry homing
04:10 PM JT-Mobile: also I would not point folks to the wiki as it is so out of date
04:11 PM Joe_Hildreth: Thanks for the link. My current router is a gantry and I would like to use the gantry homing stuff in the dev release. Started digging into it and didn't quite understand how to configure it. That was several months ago. I am using PP and BOB on my setup.
04:11 PM JT-Mobile: it's so simple
04:12 PM Joe_Hildreth: True, it is pretty outdated, but the WIKI does have some stuff there that isn't available elsewhere if I remember correctly.
04:12 PM JT-Mobile: http://linuxcnc.org/docs/devel/html/config/ini-config.html#_joint__lt_num_gt_section
04:12 PM JT-Mobile: yes there is still some really good information on the wiki like stepper spreadsheet and other stuff
04:13 PM JT-Mobile: HOME_SEQUENCE = <n> - Used to define the "Home All" sequence. <n> must start at 0 or 1 or -1. Additional sequences may be specified with numbers increasing by 1 (in absolute value). Skipping of sequence numbers is not allowed. If a HOME_SEQUENCE is omitted, the joint will not be homed by the "Home All" function. More than one joint can be homed at the same time by specifying the same sequence number for more than one
04:13 PM JT-Mobile: joint. A negative sequence number is used to defer the final move for all joints having that (negative or positive) sequence number.
04:14 PM JT-Mobile: in master to set a gantry all you do is set both joints to the same home sequence number and make at least on negative
04:16 PM pcw_mesa: Ahh that's clever
04:16 PM Joe_Hildreth: I have a XYYZ machine, I would set JOINT_0=x, _1=Y, _2=Y, _3=z in my config?
04:16 PM gloops: theres an easy to follow post on gantry in 2.8 on the forum (few slight omissions but youll get those)
04:16 PM JT-Mobile: HOME_SEQUENCE =
04:18 PM Joe_Hildreth: gloops, I will need to read it.
04:19 PM gloops: ill see if i can find it, ive got working hal and ini files
04:19 PM Deejay: gn8
04:19 PM Joe_Hildreth: Thank you.
04:20 PM gloops: ive got 5000 windows open on a 32bit here atm so might be a while lol
04:20 PM Joe_Hildreth: HAHAHA Sounds like me.
04:21 PM Joe_Hildreth: So, the MESA add on cards. Do they have hardware step generators or do you still utilize software step? Or does it just depend on the card?
04:22 PM JT-Mobile: the 7i76, 7i76e and 7i78 all use hardware step generation
04:22 PM gloops: https://forum.linuxcnc.org/49-basic-configuration/33079-how-to-2-or-more-motors-on-one-axis-gantry-linuxcnc-2-8-master
04:23 PM JT-Mobile: http://linuxcnc.org/community/
04:26 PM Joe_Hildreth: JT-Mobile, so I would need to set both the homing sequence for my two Y joints to -1 so they are syncronized?
04:27 PM JT-Mobile: you can, but only one is needed
04:27 PM JT-Mobile: setting both to negative may make reading the ini easier
04:28 PM gloops: i didnt sync mine, i let them home separately
04:28 PM Joe_Hildreth: I only need to express one of the two joints in the file, or only one joint needs to be marked as syncronized?
04:29 PM Joe_Hildreth: gloops, thank you for the link.
04:29 PM JT-Mobile: I don't understand your question
04:30 PM Joe_Hildreth: I am confused. The best thing for me is to read the docs you linked and the config post that gloops gave me and then ask questions.
04:30 PM JT-Mobile: HOME_SEQUENCE = A negative sequence number is used to defer the final move for all joints having that (negative or positive) sequence number.
04:31 PM JT-Mobile: so if you have two joints on a gantry at least one must have a negative sequence number and both must have the same sequence number
04:34 PM gloops: a bit foggy now it was 6 months ago, basically you can set both joints to search simultaneously, when 1 latches it waits for the other to latch
04:34 PM gloops: or you can just have both joints home independently
04:35 PM gloops: with a tight gantry it might be better to have them home together, i seem to remember preferring the other way though
04:35 PM Joe_Hildreth: OK, I think I get it. if I wanted to home z (joint 3) then my y axis (joint 1 and joint 2) and then x axis (joint 0) Then my sequence would be: ...
04:37 PM Joe_Hildreth: joint_0 home seq = 2, joint_1 home seq = 1, joint_2 home seq = -1, joint_3 Home seq = 0???
04:37 PM hazzy-lab: Joe_Hildreth: Very nice tutorials! In SSR there is an option to "follow cursor" or something like that, you can set a fixed recording rectangle so that terminal output and the like will be more readable, you have to be careful not to make people dizzy though :)
04:37 PM hazzy-lab: Example: https://youtu.be/VthLPpJ2no4
04:38 PM Joe_Hildreth: hazzy-lab, I cannot run SSR in wheezy as far as I can tell. Been using GTK Record my desktop on the LCNC install in next videos.
04:39 PM JT-Mobile: Joe_Hildreth, yea that is the way to home z then gantry then y
04:40 PM Joe_Hildreth: JT-Mobile, great, that helps me.
04:40 PM JT-Mobile: yw
04:41 PM Joe_Hildreth: hazzy-lab, do you know if SSR will run or is available for Wheezy?
04:41 PM hazzy-lab: Joe_Hildreth: I know I have run it on wheezy in the past, but its been a few years
04:42 PM hazzy-lab: Maybe some dependencies have changed
04:42 PM Joe_Hildreth: I know I could not find it in the repositories, but I was pressed fro time and didn't work at it to hard. That would be a good solution as long as you say, don't get people dizzy!
04:43 PM JT-Mobile: what is ssr
04:43 PM Joe_Hildreth: Simple Screen Recorder
04:43 PM hazzy-lab: Simple Screen Recorder
04:43 PM JT-Mobile: ah ok
04:46 PM Joe_Hildreth: Got to run guys. Thank you all so much for the help and links. This will get me quite a bit further on this video. I may have to come back for some details. Hope you don't mind. With luck I should have the next episode out this weekend or the first part of next week.
04:49 PM JT-Mobile: cool
04:51 PM hazzy-lab: I wonder if he might should use stretch so the videos don't get dated so fast ...
04:52 PM hazzy-lab: I guess it depends on how soon stretch will be used for the main ISO.
05:04 PM JT-Mobile: chow time here
06:22 PM andypugh: Genrally speaking RS components (major UK mail order component stockist) have fair pricing. Never cheap, but huge inventory and free next-day delivery. But this is unreasonable: https://www.geckodrive.com/g540.html https://uk.rs-online.com/web/p/stepper-drives-indexers/8968566/
06:23 PM Tom_L: 404 on that for me
06:23 PM Tom_L: nm
06:23 PM andypugh: Two separate URLS
06:23 PM Tom_L: my eyes aren't like they used to be :D
06:24 PM Tom_L: seems a bit much
06:24 PM andypugh: Quite
06:29 PM Tom_L: andypugh, any new projects you're not telling us about?
06:29 PM Tom_L: you seem to have something in the works most of the time...
06:29 PM andypugh: Nothing very CNC
06:30 PM andypugh: There;s this: https://photos.app.goo.gl/vpUza2pqMf9hnDaN8
06:30 PM Tom_L: fitting a new bottom?
06:31 PM Tom_L: i saw the pics the other day of the shelf full
06:31 PM andypugh: and this: https://photos.app.goo.gl/RuRZyxHoUKgDZjrQ9
06:32 PM andypugh: And a lot of this: https://github.com/LinuxCNC/linuxcnc/issues/451
06:33 PM Tom_L: heh
06:33 PM Tom_L: you seem to have that solved now though?
06:33 PM Tom_L: jepler or somebody
06:34 PM andypugh: Aye, Jepler managed to spot a very subtle bug.
06:34 PM andypugh: That only BSPI would ever expose.
06:42 PM Rab: andypugh, how did you bend that brass channel (or whatever it is) for the numeric display?
06:43 PM andypugh: By hand, with the help of a specal tool I made.
06:44 PM andypugh: https://photos.app.goo.gl/L3nheDstPJZYnoY27
06:46 PM andypugh: The outside groove is for holding the sides of the channel straight when bending. The central groove has a peg and two holes, that was a jig for drilling all the 1mm holes at 10mm spacing.
06:46 PM Rab: Nice!
08:06 PM infornography: *thonk* so linuxcnc is sorta like its own distro
08:11 PM infornography: oh... someone already submitted it to distrowatch
08:20 PM andypugh: Only for convenience as we are dependent on specific kernels
08:20 PM andypugh: We would like to be jusy another package
08:22 PM infornography: I prefer openbox to... whatever wm XFCE uses. What would be the easiest way to use linuxcnc and openbox?
08:23 PM infornography: Is there a option for desktops in the setup like a normal debian install?
08:24 PM andypugh: You need an RTAI or PREEMPT-RT kermel.
08:25 PM andypugh: That’s the complication
08:26 PM infornography: hum...
08:27 PM andypugh: (Actually, you can also use Xenomai, but we don’t create binary packages for Xenomai)
08:39 PM andypugh: I need to sleep now. There are instuctions on the forum for installling on Mint. Not what you want, but the principles are likely to be the same.
