[01:48:08] <gector> Guten abend from oregon
[01:48:17] <IchGucksLive> hi
[01:48:31] <gector> yeah I left IRC up

[01:51:49] <gector> I suspect there are a few going off, it's only 10:51pm
[01:51:54] <gector> I'll go check ;)
[01:52:20] <IchGucksLive> oregon is corn fieldarea is it maenshight

[06:06:10] <Tom_L> morning
[06:12:48] <Wolf__> morning
[06:14:01] <Wolf__> work and tool holding costs too much (or I need to stop ordering stuff) lol
[06:14:46] <Loetmichel> XXCoder: it peaked at 27°C this morning at home (07:30)... outside in the shadow
[06:19:14] <Wolf__> broke down and ordered a mini pallet from nycnc, time + material costs didn’t add up doing one on my manual mill
[06:21:13] <Wolf__> now to hold stuff to it, anyone use mite bites https://www.zoro.com
[06:29:05] <enleth> Wolf__: doesn't John have his own version of those too?
[06:29:24] <RyanS> is it a bad idea to run control electronics and steppers off the same transformer ( with dual rectifiers)?
[06:29:40] <Wolf__> no, only stuff for the vise thing he sells
[06:29:59] <Wolf__> not for the 1/4-20 pallet
[06:30:04] <RyanS> 70V and 5V
[06:30:06] <enleth> Wolf__: ah, so I guess he only had a video of making some of his own
[06:31:11] <Wolf__> $54 for x10 makes diy silly imo
[06:31:13] <rmu> RyanS: that doesn't make sense, get a SMPS for 5V, meanwell or similar, should only be about 3-4 beer-equivalent
[06:31:57] <Wolf__> even better get a 12v/5v supply to feed all the control stuff
[06:33:09] <enleth> rmu: the motor I was talking about yesterday: https://i.imgur.com
[06:34:44] <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
[06:35:00] <enleth> so I guess I'll try to figure out of STMBL can handle that resolver
[06:35:02] <enleth> *if
[06:37:30] <RyanS> https://www.ebay.com 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?
[06:38:33] <enleth> RyanS: the 5V part of this is not an SMPS
[06:40:29] <enleth> rmu: oh, actually the part number suggests this thing has a "multi-turn high-resolution encoder"
[06:41:45] <RyanS> no I'm just using 70V transformer psu for steppers. similar price to 4 shitty switchers of dubious origin
[06:46:22] -!- IchGucksLive has joined #linuxcnc
[06:46:29] <IchGucksLive> hi all rain outside
[06:52:36] <RyanS> those 8Nm steppers are huge would HSS57 2Nm do for the torch lifter?
[06:53:26] <Wolf__> 8nm? how big of a gantry are you planning? sounds oversized kinda
[06:54:08] <RyanS> since closed loop has 2 x the acceleration anyway
[06:54:23] -!- veek has joined #linuxcnc
[06:55:33] <RyanS> i'm thinking 4Nm closed loop
[06:56:52] <RyanS> strangely the 4Nm and 8nm are both 6A
[06:58:11] <IchGucksLive> RyanS, only the Driver is 6A
[06:58:23] <IchGucksLive> RyanS, th stepper needs 4A
[06:58:37] <RyanS> the 8nm?
[06:58:38] <IchGucksLive> the 8Nm 6A
[06:59:08] <IchGucksLive> RyanS, yoiu can run 2x 4Nm HSS57
[06:59:16] <IchGucksLive> on one psu
[06:59:35] <IchGucksLive> RyanS, the 2Nm is good for torch
[06:59:50] <IchGucksLive> RyanS, use SFU1605
[07:00:08] <IchGucksLive> or the simple 1204
[07:00:21] <RyanS> I've seen a 4Nm hss86 but not hss57 package
[07:00:22] <Wolf__> THC you think needs 2Nm?
[07:01:02] <IchGucksLive> Wolf__, no but this is the lowest Closed you can get
[07:01:10] <Wolf__> ooh
[07:04:04] <Wolf__> that sounds overkill as well, closed loop for the THC?
[07:04:35] <RyanS> is the real hbs86 an older Leadshine?
[07:07:18] <IchGucksLive> RyanS, all is leadshine OME
[07:07:23] <IchGucksLive> OEM
[07:07:50] -!- veek has quit [Quit: Leaving]
[07:08:03] <IchGucksLive> RyanS, https://www.ebay.com.au
[07:08:13] <RyanS> the Rattm motor one?
[07:08:19] <IchGucksLive> 130AU$
[07:08:29] <IchGucksLive> HBS57
[07:09:05] <RyanS> would 4Nm work without a gearbox?
[07:09:18] <IchGucksLive> yes
[07:09:31] <IchGucksLive> you are on a plasma
[07:09:39] <IchGucksLive> so it is only moving
[07:09:57] <IchGucksLive> on a good build even 2Nm may do itr
[07:10:47] <selroc> hello IchGucksLive
[07:10:56] <IchGucksLive> hi
[07:11:57] <selroc> I am ponderating about getting a used cnc to customize
[07:12:05] <RyanS> it would be good to cover the whole hypertherm range ( up to 9m/min)
[07:12:30] <IchGucksLive> RyanS, i dont think ypoiu can get it there
[07:12:53] <IchGucksLive> RyanS, this is on Welding Steel 1mm Coold down to 2DegC
[07:13:04] <IchGucksLive> flaten out
[07:13:26] <IchGucksLive> i dident make it over 5m/min on vutting with a good resault
[07:13:52] <IchGucksLive> RyanS, the air outblow is then so hard that you need hours to get it of
[07:14:31] <IchGucksLive> RyanS, while at 3.8m/min hard hit the plat to the floor and you got a razor sharp edge
[07:14:37] <IchGucksLive> clean plate
[07:14:44] <IchGucksLive> selroc, VMC ?
[07:15:13] <IchGucksLive> RyanS, seams you are stock in the construction loop
[07:15:32] <IchGucksLive> RyanS, th Mashine Hardware is the main Factor
[07:16:11] <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
[07:16:27] <selroc> ??
[07:16:40] <IchGucksLive> if you pull as a 50year Forest worker to get it moving you are at 12Nm
[07:16:56] <IchGucksLive> selroc, the remake
[07:17:17] <selroc> don't know
[07:17:29] <IchGucksLive> selroc, yesterdays work
[07:17:33] <IchGucksLive> https://www.youtube.com
[07:18:36] <IchGucksLive> RyanS, by the way this is 4m/min at 3Nm
[07:18:52] <IchGucksLive> RyanS, in this video at 0,01 Accuracy
[07:19:07] <IchGucksLive> RyanS, conventionell
[07:19:12] <IchGucksLive> low cost
[07:19:55] <IchGucksLive> complete mashine as it is shown including all 1870.-Euros
[07:20:09] <IchGucksLive> the 4th axis is not build yet
[07:20:18] <IchGucksLive> calculated costs are 2100
[07:20:52] <IchGucksLive> but they got lots of parts cheeper
[07:21:17] <IchGucksLive> THe Spindle for instand is now 260 Euros insted of calculated 320
[07:21:44] <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
[07:22:00] <IchGucksLive> yes
[07:22:06] <Wolf__> overkill
[07:22:29] <IchGucksLive> RyanS, you can get one 2Nm as you need it already and test the Y as it moves your need
[07:22:35] <Wolf__> 2nm will break a 3/8 end mill off on a small mill
[07:22:46] <selroc> IchGucksLive, interesting, but my spindle weights 27 kg
[07:23:10] <IchGucksLive> selroc, on refit go closed loop anyway
[07:23:29] <IchGucksLive> selroc, getting cheeper and cheeper
[07:24:08] <IchGucksLive> Wolf__, it is nearly the same price as a standard combinatin
[07:24:25] <IchGucksLive> Wolf__, i fully agry i stay on conventionell
[07:24:52] <IchGucksLive> Wolf__, on plasma you deal with EMI so closed loop get a real benefit
[07:24:54] <Wolf__> I have all my parts on hand except mesa card and THCad
[07:25:12] <IchGucksLive> Wolf__, why mesa
[07:25:26] <IchGucksLive> 5Axis BOB and ground is ok
[07:25:29] <Wolf__> doing ethernet
[07:25:31] <IchGucksLive> 10 USD
[07:25:36] <IchGucksLive> ok
[07:25:43] <Wolf__> but I have a bob already
[07:25:56] <enleth> nothing wrong with supporting Mesa if you can afford it
[07:26:12] <RyanS> the hypertherm manual has 7890mm/m as best quality ( not max) for 2mm aluminium so I want to aim for that
[07:26:21] <IchGucksLive> enleth, agree if your budget takes it go for
[07:26:44] <IchGucksLive> RyanS, you will see 12m/min
[07:27:04] <IchGucksLive> RyanS, as we all reatch that at plasma
[07:27:17] <IchGucksLive> the mashine
[07:27:27] <IchGucksLive> not my hypertherm45
[07:27:50] <IchGucksLive> i got max at 4m/min
[07:28:03] <IchGucksLive> Watertable
[07:28:14] <RyanS> at 45amp?
[07:28:24] <IchGucksLive> 42
[07:28:30] <Wolf__> I’ll be running a 60A machine, but my minimum thickness is around 5mm
[07:28:46] <IchGucksLive> on max it jitters the airflow
[07:29:39] <RyanS> does the manual overestimate?
[07:29:47] <IchGucksLive> yes
[07:30:01] <IchGucksLive> under full test conditions
[07:30:16] <IchGucksLive> meaninfg tuned Torches
[07:30:32] <IchGucksLive> best elektrodes frech every 10meters
[07:30:43] <IchGucksLive> i go 200meters per electrode
[07:31:13] <IchGucksLive> RyanS, and ofcause they cheet wherever they can
[07:31:53] <RyanS> maybe the XP has improved I don't know if the automatic pressure regulation help
[07:32:16] <IchGucksLive> the new elektrodes they provide with the torch are 400% the replacments
[07:32:58] <RyanS> which electrodes get 200m?
[07:32:59] <IchGucksLive> RyanS, even the oldest hypertherm from 2005 got the regulator
[07:33:43] <Wolf__> I think the new one changes the pressure with the arc voltage
[07:34:03] <RyanS> it does
[07:34:12] <IchGucksLive> Wolf__, then you are in trouble with thcad
[07:34:28] <IchGucksLive> as the systems work against etch other
[07:34:33] <Wolf__> I have a hyper them1000
[07:34:42] <Wolf__> old box
[07:35:16] <IchGucksLive> i only use S-cutter for my newer mashines
[07:35:33] <IchGucksLive> 400Euros and same then hyper
[07:36:01] <IchGucksLive> also european standard plugs so torch replacment is only 50 Euros
[07:36:51] <RyanS> you can still manually set the pressure
[07:37:14] <IchGucksLive> http://www.stamos-welding.com
[07:38:16] <Wolf__> I got mine when the powermax1000 was a new thing… so its almost 20yrs now? wait that cant be right…

[07:38:33] <RyanS> are you saying the original tips are different to the replacements?
[07:38:46] <IchGucksLive> https://www.expondo.de
[07:39:00] <IchGucksLive> RyanS, YES they are
[07:39:23] <IchGucksLive> RyanS, and you cand get the original from somwhere
[07:40:15] <RyanS> I have the replacement tips, look identical, doesn't make sense
[07:40:41] <IchGucksLive> the material sams to be not the same
[07:41:20] <IchGucksLive> i need to change waterpipes im off this discussion.

[07:47:30] <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

[08:48:09] <gloops> small plastic float - hinged on a pin as usual
[08:48:28] <gloops> the plastic bracket holding the pin - one hinge was cracked

[11:10:16] <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?

[11:21:50] <rmu> Loetmichel: there are powders that only need 160°C or so
[11:22:41] <Loetmichel> IIRC the powder coater we usualy take uses a 220°C setting on his oven
[11:28:39] <rmu> Loetmichel: ask them how to cover the holes, they should know. also, preprocesisng liquids need to drain etc...
[11:29:06] <rmu> mylar film should take the temperature. POM i suspect not.
[11:30:36] <rmu> you could make plugs out of PET soda bottles ;)
[11:34:56] <Rab> Vinyl caps are widely used for powder coat masking. Here are some other material options: https://www.stockcap.com
[11:35:59] <Rab> Actually that page contradicts me, saying standard vinyl is not recommended.
[11:37:00] <Rab> But maybe a chunk of silicone rubber would work.
[11:38:00] <Rab> In fact, a piece of soft tubing of the right diameter might conform to the dsub cutout.

[11:56:04] <gloops> like what car tyres are made from
[11:56:05] <SpeedEvil> high temp silicone sealant is cheap
[11:56:21] <gloops> get it in roll form, for roofing, pond liners etc
[11:56:35] <gloops> id imagine its a higher melting temp than vinyl

[11:59:33] <flyback> gloops, they sell rebuilt kits for most carbs
[11:59:43] <fragalot> even for trabants :P
[11:59:47] <flyback> oh you are in spain I think
[11:59:53] <flyback> your economy tanked
[12:00:00] <flyback> glue may be better
[12:00:01] <flyback> :P
[12:00:45] <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
[12:00:52] <flyback> and he tanked their economy
[12:01:41] <flyback> I like saving money fixing stuff but I have learned after many yrs some things are better just replaced or retrofitted
[12:02:38] <gloops> flyback it may come to that, ive got it running again but its only ticking over - any revs it dies
[12:02:46] -!- veek has quit [Quit: Leaving]
[12:02:57] <gloops> im guessing some water is still finding its way into the fuel, got the tank off now
[12:03:04] <flyback> or the carb has leaks
[12:03:14] <gloops> air leaks?
[12:03:15] <flyback> like the bearings are shot and leaking air
[12:03:32] <flyback> yeah I geuss the float hinges etc sometimes get so worn out and loose they leak air thru them
[12:03:35] <gloops> that would cause it rev up wouldnt it?
[12:03:35] <fragalot> or the needle valve is clogged
[12:03:41] <flyback> no
[12:03:45] <flyback> too much air is a bad thing
[12:04:16] <gloops> well, ill clean the tank out and the carb again, thats the water theory eliminated anyway
[12:04:18] * flyback bites ty2u
[12:04:21] <flyback> CANUCK
[12:04:27] <flyback> gloops, is this a tractor or something?
[12:04:36] <gloops> its an old generator
[12:04:45] <flyback> ooo cool those are always worth fixing up :)
[12:04:49] <gloops> it ran like a dream this morning for about 5 minutes
[12:04:55] <flyback> wait
[12:04:59] <flyback> it'ds not a 2 stroke is it?
[12:05:05] <gloops> yes
[12:05:10] <flyback> did you mix in oil?
[12:05:10] <gloops> oh no
[12:05:16] <gloops> no its four stroke
[12:05:28] <flyback> good :) cause 5 mins would be about right for it to shit itself :)
[12:05:37] <flyback> without oil
[12:05:40] <gloops> have had rocker cover off to see valve springs were ok
[12:05:51] <flyback> be sure to use stabil in it
[12:05:57] <gloops> its 99% either fuel or air
[12:05:59] <flyback> or whatever the local company sells
[12:06:05] <gloops> as it was full of water im thinking fuel
[12:06:16] <flyback> if your gasoline has a lot of ethanol in it
[12:06:22] <flyback> there's a bacteria that eats it
[12:06:25] <flyback> poops vinegar
[12:06:32] <flyback> which eats the hell out of alum engine parts
[12:06:42] <flyback> it froze my float valve on my generator
[12:06:51] <gloops> its new juice, but i didnt clean the tank out, i can see some jelly like shit in it
[12:07:05] <flyback> so now I use stabil with ethanol preventative in it
[12:07:14] <flyback> you can keep fuel for over a year won't go bad or acidic
[12:07:34] <gloops> its probably a blob of water/crap getting sucked to a needle valve
[12:09:42] <fragalot> flyback: or you could buy special fuel with a few decade long shelf life for a mere €4/L
[12:09:49] <fragalot> aspen fuel, I think it's called
[12:09:57] <flyback> they don't have that around here
[12:10:10] <flyback> oh you mean avation fuel?
[12:10:20] <fragalot> no
[12:10:59] <fragalot> it's basically alkylate petrol
[12:11:00] <fragalot> whatever that means
[12:12:04] <gloops> i might have altered the float height gluing that hinge, but looks perfecly aligned to me, theres no adjusting it
[12:12:21] <gloops> bowl is full every time i empty it anyway
[12:12:29] <flyback> I got a 4 stroke gen cause you can mod them to run on propane and natural gas
[12:12:43] <fragalot> gloops: typically adjusting it involves bending it :P
[12:12:52] <gloops> plastic
[12:13:10] <fragalot> Well then.
[12:14:00] <rmu> i know aspen as special 2-stroke fuel for chainsaws
[12:14:14] <fragalot> yeah they have 2 or 4stroke
[12:14:55] <gloops> i could force the spring to be a but shorter, but i dont think ill do anything like that yet
[12:14:56] <rmu> uses rapeseed oil or something so you don't contaminate your forest

[12:19:13] <flyback> gloops, there's a lot of videos etc about fixing generators etc
[12:22:09] <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

[12:53:07] <IchGucksLive> hi all
[12:53:11] <roycroft> so has anyone in the states noticed prices of imported machining gear going up yet?
[12:53:28] <roycroft> some of the websites are talking about 20% across the board price increases coming soon
[12:53:53] <IchGucksLive> Roedy, prices always go up
[12:54:04] <IchGucksLive> roycroft,
[12:54:26] <IchGucksLive> roycroft, nomater if trump or not
[12:54:33] <fragalot> 20% is al trump.
[12:54:38] <IchGucksLive> 4th july is pay day
[12:54:57] <IchGucksLive> its on Every note marked
[12:55:59] <roycroft> yes, the 20% is all trump
[12:56:07] <roycroft> it's because of the 25% tariffs he's imposed
[12:56:27] <roycroft> so he can create a few hundred jobs, will killing hundreds of thousands of jobs
[12:56:48] <fragalot> roycroft: that's a different statistic though
[12:56:49] <roycroft> i haven't seen any price inreases yet
[12:57:01] <Beachbumpete1> there must be a keystroke to toggle isometric in draftsight but damn if I can find one....
[12:57:03] <roycroft> but i am starting to see warnings that they're coming
[12:57:04] <IchGucksLive> roycroft, he might think the oposit
[12:57:23] <roycroft> of course he thinks the opposite - he's an idiot
[12:57:44] <roycroft> but that's not what i brought this up
[12:57:53] <roycroft> i'm actually just looking for real examples of the price increases
[12:58:23] <roycroft> i'm weighing prices increases against the cost of interest if i finance some stuff before they go up
[12:58:42] <roycroft> and trying to figure out when to expect the actual price increases
[12:58:55] <Rab> I heard that LittleMachineShop plans to increase prices: https://littlemachineshop.com
[12:58:56] <IchGucksLive> Beachbumpete1, tools option advance
[12:59:15] <roycroft> yes, they're one of the sources who claim to be raising prices
[12:59:18] <roycroft> but they've not done it yet
[12:59:19] <IchGucksLive> as long as rattmotor doesend do it its ok
[12:59:41] <fragalot> lol
[12:59:41] <IchGucksLive> stepperonline now got worldwide stores
[12:59:51] <Beachbumpete1> there is no tools options advance
[13:00:04] <roycroft> my local steel yard are pretty sure they're going to have to increase prices
[13:00:09] <roycroft> but again, they've not done it yet
[13:00:23] <fragalot> they may still have sufficient stock that they bought at reasonable prices
[13:00:28] <fragalot> and won't increase until they need to import more
[13:00:30] <IchGucksLive> Beachbumpete1, tools options aliases
[13:01:00] <Beachbumpete1> IchGucksLive are you pulling my leg man?
[13:01:29] <IchGucksLive> TOOLS>OPTIONS>UserPreferences>ALIASES
[13:01:57] <IchGucksLive> Beachbumpete1, what version are you on
[13:02:29] <Beachbumpete1> DraftSight 2018 x64 SP1
[13:05:20] <IchGucksLive> windoes key F5
[13:05:56] <Beachbumpete1> yeah f5 toggles the isometric axis but is there one to turn it on and off IE move back to normal mode
[13:07:26] <gloops> reports show average brit will be 2.6k a year better off
[13:08:40] <fragalot> I don't like those generic average reports
[13:08:52] <fragalot> because 1% of the population can offset those dramatically
[13:08:53] <IchGucksLive> Beachbumpete1, you can do a user shortcut to the standard view
[13:09:07] <gloops> europe and america are too rich to grow, theres no future there
[13:09:16] <IchGucksLive> gloops, are there average bits in the world
[13:09:18] <gloops> sell to the poor growing countries
[13:09:59] <gloops> Ichs well brits arent average, but there is the average brit
[13:10:15] <Beachbumpete1> hmm that would be nice. never done that before
[13:10:23] <IchGucksLive> theyare all eting strawberrys at wimbledon
[13:10:36] <gloops> yes £40
[13:10:51] <fragalot> gloops: did you know that 50% of the british population scores below average in IQ tests?
[13:10:52] <IchGucksLive> sirens sounding im off Gn8
[13:10:56] -!- IchGucksLive has quit [Quit: Leaving]
[13:11:06] <gloops> hope its not the russians Ichs
[13:11:33] <gloops> fragalot IQ is only one measure
[13:12:00] <rmu> *lol*
[13:12:01] <fragalot> gloops: well 50% of them also scores below average when it comes to critical thinking
[13:12:21] <gloops> very funny
[13:12:33] <fragalot> :-)
[13:12:37] <rmu> seems 50% of nearly everything is below average...
[13:12:52] <fragalot> rmu: give or take rounding errors
[13:12:59] <gloops> we'll be ok, its germany i fear for
[13:13:06] <rmu> and quantisation errors ;)
[13:14:42] <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
[13:15:49] <rmu> every complicated problem has a simple answer that is wrong
[13:16:35] <gloops> rmu you are fighting an economic war on 3 fronts
[13:17:02] <rmu> i am certainly not fighting any wars
[13:17:54] <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
[13:18:05] <rmu> same for euro-zone
[13:19:12] <gloops> well, it isnt looking goog
[13:19:13] <rmu> but things are interconnected in strange ways, many of them hard to quantify and hard to predict
[13:19:15] <gloops> good
[13:19:34] <rmu> maybe, but it wasn't looking good 2008 either
[13:20:15] <gloops> you must strike a favourable deal with the UK, if your cars are on WTO with the UK AND USA, its over
[13:20:56] <rmu> somebody has to build those BMW convertibles british super-rich kids like to trash in the summers
[13:21:26] <gloops> other people make cars, we can make them ourselves
[13:21:41] <rmu> IMO the problem of german car industry is not that much tariffs, but they are somehow stuck in the last century
[13:21:53] <gloops> right
[13:22:10] <rmu> yeah, USA also makes cars, but why are german cars popular, it's not because they are cheaper
[13:22:12] <gloops> dated technology, fossil fuel engines, too big to adapt in time
[13:22:49] <gloops> we buy lots of fords
[13:23:00] <rmu> electric cars are intrinsically simple, not much things to build, not much need for hundreds of different parts of engines
[13:23:32] <gloops> open to production by dynamic medium sized businesses
[13:23:36] <fragalot> rmu: yet the issue is that they seem to want to add TOO much electronics to the electric cars..
[13:24:02] <fragalot> like why on earth does tesla insist on those naff door handles that need a motor & multiple microswitches to work
[13:24:25] <rmu> the thing with electronics is, once it is designed, the rest rolls off a production line involving next to no human labor
[13:24:49] <rmu> tesla is tesla, they are somewhat stupid with those things
[13:25:17] <rmu> i also don't get how they market their cars as "quick" when you can't really go that fast for longer distances
[13:25:26] <fragalot> marketing :D
[13:25:33] <fragalot> it doesn't have to be true as long as it's technically true
[13:25:47] <rmu> but then again driving in america is surely very different to driving in especially germany
[13:25:59] <fragalot> it is
[13:26:13] <fragalot> there is a reason why the catalytic converters are in different locations in USA vs EU cars
[13:26:30] <gloops> K1 Four Wheel High Speed Electric Car
[13:26:30] <gloops> FOB Price: US $ 4300.0-7800.0 / Piece
[13:26:30] <gloops> Min. Order: 3 Pieces
[13:27:32] <Rab> Isn't that true for high-performance ICE cars as well, that top speed isn't necessarily sustainable for cruising?
[13:27:55] <fragalot> well it is
[13:28:05] <fragalot> but you need new tires after 15 minutes
[13:28:09] <rmu> the fact is that all those trade conflict in europe around brexit only increases strength of putin and china
[13:28:10] <fragalot> but that's OK because your fuel only lasts 10.
[13:28:13] <rmu> well played distraction
[13:28:45] <rmu> Rab: I have no problem goind 200kph+ for as long as fuel lasts
[13:29:32] <fragalot> rmu: well that's the same issue electric cars have isn't it?
[13:29:50] <rmu> i'm talking about practical speeds at around 100-130kph
[13:29:51] <fragalot> they can go super quick super hard as long as fuel lasts & it doesn't overheat
[13:30:38] <rmu> at that speed i have a range of about 1000km, i suspect even the 100kwh teslas only go about 200-300km at 130kph
[13:30:52] <fragalot> probably
[13:32:57] <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
[13:34:52] <rmu> strange, 155kph should not require 120kW
[13:35:28] * fragalot is seeking advice
[13:35:37] <rmu> even my old beat-up common rail minivan with 80-ish kW did 170kph
[13:35:48] <fragalot> looking for an ultra wide angle lens for landscape with a full-frame Sony E mount
[13:35:52] <fragalot> suggestions welcome
[13:36:54] <fragalot> considering the Sony FE 12-24 f4.0G, or the 16-35 f4.0
[13:37:35] <rmu> what else do you have? i quite like the 16-35, it is my "always on" lens
[13:39:27] -!- JT-Mobile has joined #linuxcnc
[13:39:48] <rmu> so it seems tesla model s needs about 300Wh/km @ 160kph
[13:40:03] <Tom_L> fragalot, https://www.bhphotovideo.com
[13:40:11] <fragalot> 35, 85, 24-240
[13:40:54] <fragalot> the 24-240 is a decent disney-lens, but the image quality is a bit meh.
[13:41:13] <fragalot> the 35 and 85 primes are mindbogglingly good
[13:41:33] -!- unterhausen has joined #linuxcnc
[13:41:49] <fragalot> Tom_L: Sony E, not Canon FE.
[13:42:17] <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 :-)
[13:42:24] <rmu> 12mm is a bit on the extreme end. i don't use the wide end of the lens much
[13:42:43] <Tom_L> https://www.bhphotovideo.com
[13:43:06] <Tom_L> https://www.bhphotovideo.com
[13:43:35] <fragalot> rmu: Yeah, I'm not too convinced I need the super wide area either
[13:43:44] <rmu> there is a new 16.35/f2.8 ;-)
[13:43:52] <fragalot> is there?
[13:44:04] <fragalot> the GM?
[13:44:12] <rmu> SEL-1635GM, but about €2k5 here
[13:44:16] <Tom_L> https://www.bhphotovideo.com
[13:44:19] <Tom_L> 18mm 2.8
[13:44:20] <rmu> and probably very heavy
[13:44:39] <fragalot> 2k7 here
[13:44:49] <fragalot> not really looking to spend more than 2k if I can avoid it
[13:44:54] <gloops> 4k for a 24mm - get samyang
[13:44:57] <Tom_L> now you're just being picky
[13:45:37] <fragalot> the batis is tempting
[13:45:55] <Tom_L> https://www.bhphotovideo.com
[13:47:03] <Tom_L> https://www.bhphotovideo.com
[13:47:05] <Tom_L> wide enough?
[13:47:23] <fragalot> I prefer rectilinear
[13:48:03] <fragalot> rmu: >.> I may just go for that 16-35 F2.8GM
[13:48:11] <Tom_L> https://www.bhphotovideo.com
[13:48:12] <gloops> sigma did the rectilinear wide
[13:48:15] <Tom_L> 21mm
[13:48:47] <rmu> 680g... not that much heavier than the /4 version
[13:49:27] <fragalot> my other lenses aren't exactly light either
[13:49:33] <fragalot> with the exception of the 35 prime
[13:49:43] <fragalot> that thing is absolutely tiny
[13:50:02] -!- JT-Mobile has quit [Quit: Leaving]
[13:50:11] <rmu> i need to take that stuff in a backpack up the mountains, so weight is a consideration
[13:50:24] <fragalot> I do too, but I just power through it like an idiot
[13:50:29] <fragalot> saving weight everywhere else, :D
[13:50:37] <rmu> hehe
[13:50:40] <rmu> sounds familiar
[13:50:56] <fragalot> every gram counts for the backpack, sleeping bag & mat, tent, etc... just to be able to carry the camera :D
[13:51:10] <rmu> 3 lenses, travel tripod, camera, replacement batteries, ...
[13:51:10] <Tom_L> sleep on the ground
[13:51:29] <rmu> the canon gear was horrible weight- and bulk-wise
[13:51:33] <fragalot> rmu: batteries is indeed one shitty thing with the a7rII
[13:52:08] <rmu> jeah, but can be mitigated a bit with a powerbank
[13:52:16] <fragalot> and a solar panel
[13:52:16] <rmu> and in-camera charging
[13:52:26] <rmu> solar panel makes exactly 0 sense
[13:52:32] <rmu> IME
[13:52:50] <fragalot> I use the solar panel to charge the battery bank
[13:52:55] <rmu> tried to kept a phone charged while doing the west highland way, no chance
[13:53:09] <fragalot> it depends on where you're going
[13:53:20] <rmu> but that solar panel needs to be HUGE
[13:53:21] <fragalot> i'm taking this to iceland where it's light 23.5hrs a day
[13:53:23] <fragalot> 20W
[13:53:41] <rmu> thats like a DIN A3 sheet?
[13:53:52] <fragalot> about the same surface as the backpack
[13:53:55] <rmu> 30×40cm?
[13:54:23] <fragalot> nearly
[13:54:25] -!- KimK has quit [Ping timeout: 245 seconds]
[13:54:44] <fragalot> doesn't weigh much, and allows everyone to scavenge power for their stuff
[13:54:52] <rmu> hmm. my panel was very small, around 100cm² at most, that was not sufficient to keep a phone charged
[13:55:02] <fragalot> no
[13:55:21] <fragalot> issue with phones is that they go "oh yeah power baby! *overclocks CPU, starts updating, ...*"
[13:55:50] <fragalot> so a 5 or 10W panel isn't going to do anything useful
[13:55:59] <fragalot> unless you have direct sunlight on it all the time
[13:56:00] <rmu> back then that was a symbian "smart" phone, didn't have much live on its own back then
[13:56:38] <rmu> and the solar panel did have its own battery pack that was charged from the sun
[13:56:46] <rmu> and then you could plugin the phone
[13:56:59] <fragalot> I had a 10W panel from goal zero,.. not incredibly useful :P
[13:57:09] <rmu> i think i managed half a phone-charge after one week of sun
[13:57:23] <fragalot> lol
[13:57:33] <fragalot> have you ever looked at laowa?
[13:57:55] <rmu> no not really
[13:58:45] <rmu> next thing i want to get is a really long tele-zoom
[13:59:01] <rmu> something in the 600mm range
[13:59:07] <fragalot> same
[14:00:36] <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 ;)
[14:00:47] <fragalot> :D
[14:00:58] <fragalot> 600mm prime isn't really all THAT useful imho
[14:01:12] <fragalot> very limited scenarios where it will work for you I think
[14:01:28] <fragalot> "oh look a bird! oh.. it's too close. hang on, sit tight little buddy whilst I switch lenses!"
[14:02:06] <rmu> i'm a bit prone to dropping lenses and cameras, so potential damage has to be kept in check
[14:02:15] <rmu> hehe
[14:02:34] <fragalot> hehe
[14:02:35] <rmu> yeah, 600mm prime is not that useful
[14:02:54] <fragalot> in terms of dropping lenses,.. I've been using the spider holster for a few years now
[14:03:03] <fragalot> absolutely fantastic thing.
[14:03:40] <rmu> it happens mostly when preparing "for takeoff" or doing something like putting camera into backpack or taking it out
[14:03:54] <rmu> or forgetting to close the backpack...
[14:04:13] <rmu> don't want to think about it
[14:04:24] <fragalot> https://www.cameranu.nl <== other variations exist, this is the one i've got
[14:04:41] <fragalot> no problem climing or jumping around, camera stays nicely attached to your hip
[14:04:52] <rmu> will check it out
[14:05:44] <rmu> ok, i have to go. keep us informed what lens you get and how it performs in the midnight sun ;)
[14:06:00] <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
[14:06:10] <fragalot> and it does hang differently compared to only the pin
[14:06:17] <fragalot> so i'll see if I still like it or not :P
[14:06:24] <fragalot> Alright! ttyl!

[15:10:48] -!- swarfer has quit [Quit: swarfer]
[15:12:12] <gloops> leverage, shock loading, aggression etc all good ways to free a nut
[15:13:27] <fragalot> or break the stud
[15:13:31] <fragalot> :-)
[15:13:56] -!- KimK has joined #linuxcnc
[15:15:09] <gloops> worst case scenario - nut in a place where a hammer cant be swung or a bar rotated
[15:15:18] <Loetmichel> fragalot: no way you break a 1 1/4" steel pipe or the cast iron pump base.
[15:15:59] <gloops> Loetmichel very short strokes with a piece of hacksaw blade - for a long time
[15:15:59] <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.
[15:18:19] <gloops> i think theres an overlooked factor in nut freeing as well - time
[15:18:34] <fragalot> sure
[15:18:38] <fragalot> wait longer and it gets worse
[15:18:40] <gloops> sometimes you just chisel and yank away at a nut with no progress for ages
[15:18:46] <fragalot> or wait even longer and the problem solves itself
[15:18:49] <gloops> then suddenly - its free
[15:18:55] <gloops> not doing anything different
[15:20:08] <XXCoder> Loetmichel: reminds me of one algbera question that was made from real life event
[15:20:23] <XXCoder> answer was over million ft/lb lol
[15:20:42] <Loetmichel> what, long lever and a tiny force to a short lever?
[15:20:48] <XXCoder> basically guy was trying to remove bolt from one of semi tires, and it was stuck
[15:21:00] <XXCoder> so he took 20 feet long pipe to it, and used his entire weight
[15:21:11] <XXCoder> guess what happened?
[15:21:58] <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...
[15:22:12] <XXCoder> heh nut shattered, and ruined the thread
[15:22:22] <XXCoder> he had to replace it, much costly job
[15:22:24] <Loetmichel> we sheared off the bolts
[15:22:45] <Loetmichel> not a big deal, they are only pressed in from the back side with fine teeth
[15:23:22] <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
[15:23:26] <fragalot> yeah replacing the studs is easy
[15:23:34] <fragalot> Loetmichel: ... or a press. :P
[15:23:52] <Loetmichel> then i had to remove the hub... nope, way to much work ;)
[15:24:00] <XXCoder> from what I recall, that part was destroyed also
[15:24:07] <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.
[15:24:10] <XXCoder> not just threads
[15:24:41] <Loetmichel> it was THIS truck: http://www.cyrom.org
[15:24:52] <XXCoder> Rab: left loosen mark ;)
[15:24:56] <Loetmichel> and i doubt anyone had changed the tyrs in the last 20 years ;)
[15:25:05] <Rab> XXCoder, yeah, "left hand thread".
[15:25:18] <XXCoder> lol thats even worse
[15:26:22] <Rab> I still have a pic: http://reboots.g-cipher.net
[15:26:36] <XXCoder> nice and smooth
[15:27:01] <XXCoder> 6 feet but much more mass
[15:28:12] <jesseg> hey anyone know which pins on the atmega128-16ua 64 qfp

[15:30:08] <jesseg> Rab, I think so - I ordered this: https://www.ebay.com
[15:31:25] <Rab> jesseg, see pp. 300 of the datasheet: http://ww1.microchip.com

[15:35:31] <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.
[15:36:39] <Loetmichel> Rab: nice thing the stripped threads
[15:36:40] <Rab> I might have dropped the chip on a board with PB0-PB3 wired for ISP and wondered why it didn't work.

[16:45:16] <Joe_Hildreth> Anyone have time for some simple I/O questions?
[16:45:37] <JT-Mobile> we just ask the questions here
[16:46:09] <Joe_Hildreth> OK, I know that _MOST_ hobbyist will use the parallel port for their cnc projects.
[16:46:28] <Joe_Hildreth> But, I know there are several add on cards that can be used for IO.
[16:47:04] <Joe_Hildreth> For an entry level user who will use steppers, what hostmot (???) cards would be suggested?
[16:47:16] <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...
[16:47:30] <Joe_Hildreth> I am working on another CNC for the home hobbyist video and am discussing I/O options for LCNC
[16:47:32] <JT-Mobile> 7i76, 7i76e
[16:47:49] <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
[16:47:53] -!- KimK has quit [Ping timeout: 265 seconds]
[16:48:15] <JT-Mobile> also 7i78
[16:48:25] <JT-Mobile> https://mesaus.com
[16:48:30] <Joe_Hildreth> As I understand, some of these are PCI cards and others are Ethernet?
[16:48:34] <JT-Mobile> https://mesaus.com
[16:49:12] <JT-Mobile> yep the 7i76 and 7i78 are daughter cards and need a 5i25/6i25 or 7i92
[16:49:34] <JT-Mobile> the 7i92 and 7i76e are both ethernet
[16:50:18] <JT-Mobile> ethernet cards require LinuxCNC Uspace which is now very easy to install
[16:50:36] <Joe_Hildreth> JT-Mobile, Thanks for the links.
[16:50:47] <JT-Mobile> https://mesaus.com
[16:50:59] <JT-Mobile> check out my fancy chart on the home page :)
[16:51:12] <Joe_Hildreth> I am basing on the premise that the ISO will be installed.
[16:51:17] <Joe_Hildreth> Will do, brb
[16:51:46] <Roguish> JT-Mobile: nice chart...........
[16:51:57] <Roguish> seriously
[16:52:08] <Joe_Hildreth> May I use your graphic in my presentation? I will give you attribution.
[16:52:12] <Roguish> oh shit, links and all....
[16:52:25] <JT-Mobile> I'll be here for a little while then we are going to Pappadeaux for dinner
[16:52:32] <JT-Mobile> hey Roguish
[16:52:51] <JT-Mobile> Joe_Hildreth, sure all my stuff is ok to use
[16:53:18] <JT-Mobile> Roguish, that was actually challenging to do lol
[16:53:33] <JT-Mobile> we are down in Fort Worth
[16:53:40] <Roguish> i'm sure, since you code it by hand.
[16:53:46] <JT-Mobile> aye
[16:53:47] <Joe_Hildreth> Thank you. If your interested in what I am trying to do, a link is here: https://www.youtube.com
[16:54:11] <Joe_Hildreth> Constructive criticism is welcome BTW
[16:54:20] <JT-Mobile> Joe_Hildreth, cool
[16:55:56] <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.
[16:56:47] <Joe_Hildreth> Or maybe organize the madness. :-)
[16:57:14] <JT-Mobile> the screen shots are a bit blurred for me dunno
[16:57:26] <JT-Mobile> also a link to a step by step would be nice
[16:57:35] <JT-Mobile> I smell a new showcase...
[16:58:04] <JT-Mobile> if you could zoom in so the text is readable that would be great
[16:58:26] <Joe_Hildreth> To which part are you referring? The computer screen casts or something else?
[16:58:32] <JT-Mobile> 003
[16:59:00] <JT-Mobile> like the terminal zoom it in real big for old tired eyes
[16:59:28] <Joe_Hildreth> Good point. Will have to try to fugure out what tool to use to do that. Any suggestions?
[17:00:02] <JT-Mobile> how did you record the screen?
[17:01:02] <JT-Mobile> I applaud that you don't have all that crap in your videos like most do
[17:01:29] <Joe_Hildreth> Ubuntu desktop was recorded with SimpleScreenRecorder, the screen casts of LCNC was done with gtk Record My Desktop
[17:01:58] <JT-Mobile> I've not messed with them much
[17:02:08] <Joe_Hildreth> What crap is that? The annoying music?
[17:02:41] <JT-Mobile> all the self promoting and trying to be a star lol
[17:02:55] <Joe_Hildreth> From here out, most of the recording will be done on a Debian install of LCNC.
[17:02:58] <Tom_L> 7i90 is a good parallel port mesa card
[17:03:06] <Tom_L> better than the 7i43
[17:03:15] <Tom_L> cheaper too
[17:03:18] <JT-Mobile> you get to the point and don't dabble I like that
[17:03:22] <Joe_Hildreth> Oh, well, I do suggest people subscribe if they like the videos. So maybe I am guilty!
[17:03:43] <JT-Mobile> not in my eyes
[17:04:09] <Joe_Hildreth> Thanks Tom_L. I am going to copy this session to a text file so I can digest the details later.
[17:04:25] <JT-Mobile> see if you can figure out how to zoom to the terminal window
[17:05:10] -!- Motioncontrol has quit [Quit: Sto andando via]
[17:05:14] <JT-Mobile> yes there are lots of 50 pin card options
[17:05:21] <Tom_L> jt, hot in Tx?
[17:05:24] <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.
[17:05:27] <JT-Mobile> 5i24 and 6i24
[17:05:59] <Tom_L> and
[17:06:19] <Tom_L> 7i80 is a direct drop in for 7i90 if you want ethernet instead
[17:06:26] <JT-Mobile> Tom_L, not too bad... we went to the botanical gardens this morning and the cabin display this afternoon
[17:06:28] <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.

[17:09:57] <JT-Mobile> the development version has some important features like gantry homing
[17:10:54] <JT-Mobile> also I would not point folks to the wiki as it is so out of date
[17:11:21] <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.
[17:11:35] -!- KimK has quit [Ping timeout: 240 seconds]
[17:11:41] <JT-Mobile> it's so simple
[17:12:10] <Joe_Hildreth> True, it is pretty outdated, but the WIKI does have some stuff there that isn't available elsewhere if I remember correctly.
[17:12:22] <JT-Mobile> http://linuxcnc.org
[17:12:54] <JT-Mobile> yes there is still some really good information on the wiki like stepper spreadsheet and other stuff
[17:13:12] <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
[17:13:12] <JT-Mobile> joint. A negative sequence number is used to defer the final move for all joints having that (negative or positive) sequence number.
[17:13:59] <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
[17:15:55] <pcw_mesa> Ahh that's clever
[17:15:58] <Joe_Hildreth> I have a XYYZ machine, I would set JOINT_0=x, _1=Y, _2=Y, _3=z in my config?
[17:16:22] <gloops> theres an easy to follow post on gantry in 2.8 on the forum (few slight omissions but youll get those)
[17:16:30] <JT-Mobile> HOME_SEQUENCE =
[17:18:31] <Joe_Hildreth> gloops, I will need to read it.
[17:19:01] <gloops> ill see if i can find it, ive got working hal and ini files

[17:20:29] <Joe_Hildreth> HAHAHA Sounds like me.
[17:21:11] <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?
[17:22:28] <JT-Mobile> the 7i76, 7i76e and 7i78 all use hardware step generation

[17:26:00] -!- FAalbers has quit [Quit: Leaving]
[17:26:40] <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?
[17:26:48] -!- jasen has joined #linuxcnc
[17:27:08] <JT-Mobile> you can, but only one is needed
[17:27:24] -!- ve7it has quit [Remote host closed the connection]
[17:27:41] <JT-Mobile> setting both to negative may make reading the ini easier
[17:28:15] <gloops> i didnt sync mine, i let them home separately
[17:28:34] <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?
[17:29:07] <Joe_Hildreth> gloops, thank you for the link.
[17:29:15] <JT-Mobile> I don't understand your question
[17:30:15] <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.
[17:30:20] <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.
[17:31:17] <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
[17:34:16] <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
[17:34:40] <gloops> or you can just have both joints home independently
[17:35:33] <gloops> with a tight gantry it might be better to have them home together, i seem to remember preferring the other way though
[17:35:40] <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: ...
[17:37:10] <Joe_Hildreth> joint_0 home seq = 2, joint_1 home seq = 1, joint_2 home seq = -1, joint_3 Home seq = 0???
[17:37:41] <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 :)
[17:37:54] <hazzy-lab> Example: https://youtu.be
[17:38:53] <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.
[17:39:17] <JT-Mobile> Joe_Hildreth, yea that is the way to home z then gantry then y
[17:40:05] <Joe_Hildreth> JT-Mobile, great, that helps me.
[17:40:13] <JT-Mobile> yw
[17:41:12] <Joe_Hildreth> hazzy-lab, do you know if SSR will run or is available for Wheezy?
[17:41:35] <hazzy-lab> Joe_Hildreth: I know I have run it on wheezy in the past, but its been a few years
[17:41:57] <hazzy-lab> Maybe some dependencies have changed
[17:42:50] <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!
[17:43:06] <JT-Mobile> what is ssr
[17:43:21] <Joe_Hildreth> Simple Screen Recorder

[19:46:02] <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.

[21:06:37] <infornography> *thonk* so linuxcnc is sorta like its own distro
[21:11:39] <infornography> oh... someone already submitted it to distrowatch

[21:19:55] <andypugh> Only for convenience as we are dependent on specific kernels
[21:20:16] <andypugh> We would like to be jusy another package
[21:22:44] <infornography> I prefer openbox to... whatever wm XFCE uses. What would be the easiest way to use linuxcnc and openbox?
[21:23:50] <infornography> Is there a option for desktops in the setup like a normal debian install?
[21:24:47] <andypugh> You need an RTAI or PREEMPT-RT kermel.
[21:25:16] <andypugh> That’s the complication
[21:26:20] <infornography> hum...
[21:27:53] <andypugh> (Actually, you can also use Xenomai, but we don’t create binary packages for Xenomai)
[21:38:57] <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.
