[01:22:45] <fragalot> hi
[01:24:36] -!- ziper has quit [Read error: Connection reset by peer]
[01:25:15] <miss0r> youly :P
[01:25:23] <miss0r> you're up early...
[01:25:28] <miss0r> damn, how did that happen
[01:25:40] <fragalot> because it's early? (it's not really any more)
[01:25:49] <miss0r> yeah, not realy
[01:25:52] <fragalot> i'm generally up by 6.30
[01:26:00] <miss0r> yeah. me too
[01:26:34] <miss0r> strange stuff; I'm quite positive I typed all of it, and it came out "youly :P" on the screen
[01:26:44] <miss0r> I must have had the computer freeze for a sec
[01:26:51] <fragalot> Sure. :D
[01:27:30] <miss0r> wouldn't be the first time. I made mistakenly installed a driver package for the toughbook on this pc. It is pretty messed up at the moment
[01:27:39] <fragalot> lol
[01:27:48] <miss0r> like; it can take up to two minuts for it to realize it has a network connection after a reboot
[01:28:10] <miss0r> and it sometimes freeze for no apparent reason(but unfreezes shortly after)
[01:28:11] <fragalot> can you not roll back?
[01:28:42] <miss0r> that would have required me to make a rollback point myself. The driver software didn't
[01:28:56] <fragalot> :(
[01:28:59] <miss0r> yeah
[01:29:24] <miss0r> oh well.. Its about time for a reformat anyway
[01:29:44] <fragalot> right, i'm off to workµ
[01:29:45] <fragalot> ttyl
[01:29:49] <miss0r> have a good one

[01:36:24] * `Wolf waits for his laundry to dry…
[01:36:52] <`Wolf> long work days lately
[01:38:25] <`Wolf> I really need to find time now to get that cnc plasma build started
[01:46:55] -!- m0n5t3r has joined #linuxcnc
[01:47:39] -!- Wolf__ has joined #linuxcnc
[01:55:40] <miss0r> 'wolf: you have me curious; what is it you do for a living, if you don't mind me asking?
[02:06:34] <Wolf__> https://i.imgur.com
[02:06:49] <Wolf__> commercial truck stuff
[02:07:19] <Wolf__> welding/fabrication, installs, hydraulics, control systems
[02:10:38] <Wolf__> I think we have 9 of those trash trucks lined up for installs plus 5-6 hook truck systems https://i.imgur.com (like this but bigger)
[02:11:47] <Wolf__> I should have some better pics of the work by the end of the week, I need to redo my website
[02:12:06] <miss0r> nice
[02:12:20] <miss0r> So all around fabrication, including the more advanced stuff
[02:12:25] <Wolf__> yup
[02:12:41] <Wolf__> had to buy a new plasma cutter today
[02:12:54] <miss0r> had to or wanted to ? :D
[02:13:28] <Wolf__> torch lead got damaged on my 65A machine and needed one running asap lol
[02:13:40] <Wolf__> picked up a hypertherm 30xp
[02:14:07] <miss0r> nice :) so, is it your company?
[02:14:18] <Wolf__> half the amps, 1/3rd the size lol
[02:14:41] <Wolf__> yeah me and friend of mine
[02:14:43] <miss0r> well, when you need one you need one
[02:15:00] <miss0r> cool :) I have no idea so many selfemployed people were in here to be honnest
[02:15:48] <Wolf__> yup, had to take a 1/2” 4x4’ plate to a knife and sword shop that another friend owns to cut it yesterday, used his plasma table much nice
[02:16:02] <Wolf__> really really want a cnc plasma setup now lol
[02:17:07] <miss0r> :D
[02:17:11] <miss0r> who doesn't :D
[02:18:06] <Wolf__> made 2 bumper tubes up like this one https://i.imgur.com beats doing them by hand or hole saw bit
[02:18:42] <Wolf__> I did those free hand…
[02:18:55] <miss0r> damn
[02:19:13] <miss0r> Well, they look pretty good for a 'hand job' (pun intented)
[02:19:20] <Wolf__> lol
[02:19:44] <miss0r> I can see why you'd want a plasma CNC.
[02:19:59] <Wolf__> worst part is the tube stock we have is 1/4” (6mm) wall so hole saw sucks
[02:20:00] <miss0r> I wouldn't mind having one either. I just haven't got any more room in here
[02:20:21] <Wolf__> I dont either, building a clone of a esab crossbow
[02:20:54] <miss0r> thats the portable one, right?
[02:21:20] <Wolf__> yeah, plan to make it so I can store it like a hand truck
[02:22:02] <miss0r> so the arm swings up or something?
[02:22:42] <Wolf__> https://www.weldingsuppliesfromioc.com
[02:23:51] <miss0r> wow. That is alot cheaper than I thought
[02:24:24] <Wolf__> I’ll just put a set of wheels + foot that clamps to the end so I can stand it up out of the way when not in use
[02:24:38] <miss0r> I don't suppose that includes the actual plasma generator?
[02:25:04] <Wolf__> I think thats without the plasma box
[02:25:24] <miss0r> oh well. Plasma generators are cheap now'a'days anyway
[02:25:40] <Wolf__> sorta, one I want now is almost $3000 usd
[02:25:54] <miss0r> I can see why you'd want one of these, now I want one too! :D but theres no way in hell I can fit it in here
[02:27:18] <Wolf__> the 30xp I picked up today was $1300, $400 for a new hand torch for my hypertherm 1000
[02:28:23] <miss0r> hmm... Okay, they are more expensive that I thought. But nontheless. They are still alot cheaper than 20 years ago
[02:28:46] <Wolf__> name brands are about same price lol
[02:29:09] <Wolf__> my 1000 is over 12yrs old
[02:30:25] <miss0r> must be the right quality
[02:30:53] <Wolf__> whole idea for that single arm, rail carriage cnc is you dont need room except when you are using it
[02:31:11] <miss0r> Wolf__: This is the situation in my shop at the moment, you can see why I would not be able to fit anymore into this mess: https://imgur.com
[02:31:43] -!- arekm has quit [Remote host closed the connection]
[02:31:57] <Wolf__> lol yeah that is tight
[02:32:03] <miss0r> yeah
[02:32:44] <Wolf__> right now neither shop we use has room to get the trucks inside to work on them
[02:32:53] <Wolf__> my shop is too small
[02:32:57] <miss0r> I'm thinking, in perhaps two years(if things keep going like they are now) I will build a new shop. you know; with good insulation all around, white/grey epoxy floor, sounddamping ceiling ect
[02:33:00] <Loetmichel> thats no mess. thats nice and clean (if a bit cramped)
[02:33:09] <Wolf__> other one is full of stuff =/
[02:33:32] <miss0r> Loetmichel: Thanks, but I feel it is messy
[02:34:16] <Wolf__> https://i.imgur.com is a mess
[02:34:42] <Wolf__> worse now, cant barely walk in it right now
[02:34:51] <miss0r> alright. You run a buisness in there? :D
[02:35:11] <Wolf__> right now all out of the 2nd location
[02:35:26] <miss0r> alright, I would be afraid to scare off clients then :) I already am
[02:35:53] <Wolf__> only 1 client lol
[02:36:04] <miss0r> That helps, I guess
[02:36:06] <miss0r> :D
[02:36:30] <Wolf__> we are hooked up with a big dealer that doesn’t do installs lol
[02:37:06] -!- gloops has joined #linuxcnc
[02:37:44] <miss0r> That sounds like a nice setup
[02:37:51] <miss0r> I have alot of small clients
[02:37:56] <Wolf__> means we dont make sales but on the other hand means we dont have out of pocket to float inventory
[02:39:01] <miss0r> yeah. Sounds like a pretty sweet buisness model there. So is it only your buddy'n you?
[02:39:08] <Wolf__> yup
[02:40:02] <Wolf__> finally picking up, we are a dealer for the hook systems but no one wants to fork out a deposit for a $22,000 system and then need to wait for 3 months for the thing to show up
[02:40:30] <miss0r> nice. I sometimes need another person here, but I have decided not to hire.
[02:40:56] <miss0r> so, you keep them stocked?
[02:41:14] <Wolf__> we dont have that kinda cashflow yet lol
[02:42:02] <miss0r> I guess I was lucky with my buisness here. I started march of this year.(full time that is). and I've been able to pay myself salary from the first month
[02:42:09] <Wolf__> last time we got stuff for stock it ended up biting us in the ass
[02:43:13] <miss0r> yeah, you gotta be carefull with that stuff
[02:43:42] <Wolf__> have had 2 switch’n go systems ( https://www.switchngo.com ) just sitting for 7 yrs now cant get the damn things sold
[02:44:45] <miss0r> that don't look cheap
[02:45:07] <Wolf__> like $12,000 installed
[02:45:18] <miss0r> why don't you ask your dealer to do you a solid one, and sell them for you?
[02:45:41] <Wolf__> these are like toys vs the stuff we are doing for them
[02:46:08] <miss0r> well, atleast ask them to keep it in mind, should the job come along where it could be used.
[02:46:26] <miss0r> y'know - sell them at a discount
[02:46:51] <Wolf__> have to at this point long as they have been sitting lol
[02:47:02] <miss0r> :D
[02:47:29] <miss0r> I'm sad that you live all the way 'over there'. I wouldn't mind making some special parts for you once in a while :)
[02:48:40] <Wolf__> lol, I’m working on getting setup to do everything in house possible
[02:50:02] <Wolf__> I know I’m glad that I got a parker hydraulic hose crimper when I was putting my truck together 6 yrs ago
[02:51:46] <miss0r> Yeah.
[02:52:06] <miss0r> Duty calls. A mill is eating fuses for breakfast, I have to run.

[02:59:37] <jesseg> The problem turned out to be a 3 inch (77mm) length of electrical tape stuck in the check valve in the fuel line LOL

[06:06:30] <fragalot> ctrl alt F2
[06:06:33] <fragalot> iirc
[06:06:41] <fragalot> that will pop you out of X into a terminal
[06:06:53] <fragalot> one of the Fx keys will be able to bring you back to X
[06:06:56] <fragalot> can't remember which one
[06:08:05] <XXCoder> ya took me bit but was already using term :)
[06:08:49] <XXCoder> yay!
[06:08:51] <jthornton> yea ctrl alt t will open a terminal
[06:09:03] <XXCoder> trying to kill java (minecraft) caused it to lose focus
[06:09:08] <XXCoder> which returned mouse to me
[06:09:22] <XXCoder> yep minecraft still frozen

[07:44:09] <rmu|w> Loetmichel: why don't you get your sheet metal stuff from some specialized shop, this seems to be an application for a trumpf truepunch or similar machine
[07:45:29] -!- holzjunkie1 has joined #linuxcnc
[07:56:58] <fragalot> rmu|w: because his boss doesn't understand the concept of "RoI" :)
[07:57:45] <fragalot> (only reason I could think of would be delivery time & one-offs)

[08:02:35] -!- Xsankor has quit [Quit: Leaving]
[08:04:27] <Loetmichel> rmu|w: we so... when making series
[08:04:35] <Loetmichel> prototypes and single digit series in house
[08:05:42] <fragalot> with prices that you can get things lasercut at these days i'd find it hard to justify doing these things in-house anymore even for single digit units
[08:06:01] <fragalot> we send an undimensioned .dxf to our supplier and get the part 2 days later
[08:09:49] <Loetmichel> fragalot: then lets see how you can hold delivery dates when your boss comes around "next week we have to deliver 12 of them" start designing!"
[08:10:23] <fragalot> I did say the only reason is lead-time :)
[08:10:29] <Loetmichel> its not about price, its about "time to market"
[08:11:33] <Loetmichel> also: whe you design stuff in 2d that has to be 3d at the customer sometimes you need 2 or three iterations until everything fits
[08:12:26] <Loetmichel> when you do that with external sheet metal guys you will have "fun" explaining why the dxfs you sent doesnt fit and why he can scrap a whole series ;)
[08:15:53] <fragalot> we design in 3D, send 3D model, so far 98% of what we receive from them fits
[08:19:40] <Loetmichel> in short its just better to have the capability to do prottypes in house
[08:20:00] <Loetmichel> and be it just to save time from "idea" to something the boss can grab and inspect
[08:20:13] <Loetmichel> and make "suggestions" how to make it better...
[08:28:34] <rmu|w> our sheet metal guys deliver cut, bent and powder-coated
[08:29:11] <rmu|w> lead time is another issue, but not that bad if you don't need coating

[08:40:20] <miss0r> I wonder how square those hex ER-32 chinesium blocks are.
[08:41:00] * miss0r is wondering if he should not just make one himself and just skip the frustration part
[08:47:43] <fragalot> miss0r: I've got one at home.. want me to check it?
[08:48:15] <miss0r> That would be nice. what I want to know: if you have a ground rod clamped in it, and have it resting on one side, is the rod parallel to the table
[08:48:27] <fragalot> ok
[08:48:37] <miss0r> that'd be sweet :]
[08:49:05] <miss0r> Just looking at the pictures of the ones on ebay - they couldn't even find one that didn't have scratches and deep marks on it for the photo

[08:49:17] <miss0r> also, the "ground" taper, looks like poop
[08:49:17] <fragalot> I couldn't even find any on ebay when I last looked (a year ago)
[08:49:27] <fragalot> I got mine from arcEurotrade
[08:49:45] <miss0r> well, if it is good, I'd love to see a link for it

[14:48:46] <fragalot> hi
[14:51:03] <dasbrow> I need some help with setting up my step conf. I am using DQ542ma stepper drivers, currently set to 25000 pulse/rev. Current is set to peak 4.20amp, rms 3.0, step set up in stepconf is 200 steps per rev motor which is correct, driver micro stepping 64, max acc 100, max vel 6. Can't seem to get it to go faster.
[14:52:33] <fragalot> 200 steps/rev & 64x micro-stepping would make it 12800 steps/rev
[14:52:34] <dasbrow> I've set the driver to 800 pulse/rev at 4 microstepping and the stepper's won't move the table.
[14:52:51] <fragalot> since your drive is set to 25000, that's not right
[14:53:00] <fragalot> Right
[14:53:19] <fragalot> could you leave the driver at 800 pulses/rev, and set your stepconf to 800 steps/rev, microstep 1
[14:53:33] <dasbrow> let me try it..
[14:54:49] <dasbrow> table does move when set to 800p/r
[14:55:17] <fragalot> does it move the right amount you expect it to?
[14:55:37] <dasbrow> sorry, I meant it does not move.
[14:55:50] <fragalot> does it make noise like it's trying?
[14:55:51] <JT-Shop> wow 64 micro stepping
[14:56:27] <dasbrow> yes it does
[14:56:31] -!- phiscribe has joined #linuxcnc
[14:56:46] <dasbrow> I thought 64 micro stepping was high too.
[14:57:04] <JT-Shop> can you change it?
[14:57:09] <fragalot> JT-Shop: he already has to 4x
[14:57:49] <fragalot> dasbrow: does the motor move if it's not actually connected to the leadscrew?
[14:58:00] <fragalot> and does the leadscrew move freely if you try it without the motor enabled
[14:58:30] <dasbrow> it would for sure, it's just locking up. moves freely with hand wheel.

[15:01:00] <dasbrow> it works fine when I have the driver set to 25000 p/r and set to 64 micro steps.
[15:01:13] <dasbrow> just slow
[15:01:58] <XXCoder> I hate fake gifs
[15:02:01] <fragalot> perhaps your acceleration is too high then
[15:02:07] <XXCoder> just use mng or something
[15:02:37] <XXCoder> or apng
[15:03:35] <XXCoder> example of apng https://www.bram.us
[15:05:20] <dasbrow> just checked wiring, it is fine.
[15:05:28] <dasbrow> maybe a bad power supply.
[15:05:48] <JT-Shop> dasbrow: I assume your using metric?
[15:06:15] <dasbrow> JT-Shop: no imperial. (you assumed because I am canadian eh?)
[15:06:31] <JT-Shop> yea it was the accent lol
[15:06:47] <JT-Shop> what voltage is the power supply for the stepper drives?

[15:24:12] <CaptHindsight> I was looking for a CNC airbrush for painting the surfaces of parts with lots of contours and pockets
[15:24:20] <fragalot> it's due to arrive thursday
[15:25:15] <CaptHindsight> I only found 2D for graphics and multiaxis for monocolor coatings
[15:25:42] <CaptHindsight> no airbrush graphics for 3d shapes

[15:51:53] <miss0r> fragalot: also, I was phoned earlier about making four 25mm bores in a block of steel. The steel block is 310mm tall, and the bores need to be 280mm deep.
[15:52:18] <fragalot> miss0r: gun drill or burn it out
[15:52:53] <miss0r> fragalot: I'm thinking regular indexable drill
[15:53:18] <miss0r> The thing is; I need to remove the angle head on my cnc, and use the Y-direction to get the travel + "height" I need
[15:53:22] <fragalot> could work, never really used those myself so I have no idea how "on target" those stay
[15:53:29] -!- W1N9Zr0 has joined #linuxcnc
[15:53:42] <fragalot> miss0r: horizontal?
[15:53:45] <miss0r> They do alright. Not precision bore though. and that is not needed anyway
[15:53:47] <miss0r> yeah
[15:53:54] <fragalot> long live horizontal :D
[15:54:04] <miss0r> I 'only' have 500mm from the table to the spindle nose
[15:54:16] <fragalot> remove the table :D
[15:54:44] <miss0r> yeah... I 'could' do that, but it is hell leveling it out again :D
[15:54:49] <fragalot> I dunno why but when you mention things I immediately assume high precision is required >.>
[15:54:52] <miss0r> its much easier to re tram the head
[15:55:15] -!- njh has joined #linuxcnc
[15:55:21] <miss0r> lol. Well, you know me; even when high precision is not required or even called for - I have a nasty way of doing it anyway :P
[15:55:52] <fragalot> perfect slip fit tolerance for a bolt hole
[15:56:10] <miss0r> it is for a guide of some sort. for a high pressure steam valve
[15:56:15] <fragalot> colleague of mine does that on his damn drawings & then things don't line up exactly right and the thing doesn't bolt together
[15:56:19] <miss0r> but for some reason, they don't need to be precise
[15:56:29] <miss0r> the issue is just the depth of cut
[15:56:58] <fragalot> should be fine with an indexable drill if you find one that's long enough then
[15:57:05] <fragalot> worst case you can even use them to bore it out
[15:57:07] <miss0r> yeah
[15:57:18] -!- hazzy-lab has joined #linuxcnc
[15:57:55] <miss0r> I'm hoping I can get a drill that can do it in one go
[15:58:10] <miss0r> preferably one that is already fixed in an SK40 taper
[15:58:19] <fragalot> pricey
[15:58:28] <miss0r> so I don't have to have the workpiece hang too far off the table
[15:58:54] <fragalot> you can't use it in your lathe afterwards though if it's SK40

[15:59:56] <miss0r> its okay. I'm fine with the tool being for the mill
[16:00:02] <miss0r> Its gonna be expensive I think
[16:00:12] <fragalot> 300+ at least for a standard length

[16:02:29] <fragalot> miss0r: if it's not ultra precise, and you only need 4 holes.. why not a fresh ground standard integrated mk3 drill?
[16:02:43] <fragalot> miss0r: because they're like 20x cheaper, and in the end it's only 12D deep

[17:58:43] <CaptHindsight> how many things are wrong with this article?
[17:59:21] <CaptHindsight> Child chews plastic toy into shape pf F-35 landing gear component for 2 cents
[18:03:19] <MarcelineVQ> "The original part was plastic; the replacement part was made of [cheap plastic]."
[18:04:09] <MarcelineVQ> a PET part being allowed to be put in landing gear of a machine worth millions?​ when pigs fly a base commander would allow that
[18:04:16] <andypugh> ~Surely the question they should be asking is _why_ they can’t buy just the part separate from the entire door.

[21:23:35] <enleth> so I had this idea a couple years ago to mount the toolhead on a non-contact plotter-like gantry machine (such as a plasma cutter) on a small, limited range X-Y stage, in addition to the regular X (gantry) and Y (linear stage on the gantry) axes
[21:23:50] <enleth> or perhaps just an additional linear stage parallel to X
[21:25:16] <enleth> the idea here being to split the toolpath in frequency domain and use the small stage for the high frequency part
[21:25:53] <enleth> never tried it, mostly for the lack of software support in pretty much any machine control out there
[21:27:39] <enleth> and now I'm wondering how much work would it take to get LinuxCNC to understand and use such a configuration
[21:29:19] <enleth> obviously the whole point is being able to run detailed toolpaths fast on a machine that would otherwise lack the rigidity and/or power to do that
[21:29:37] <enleth> any thoughts?
[21:31:15] <_unreal_> What are you asking
[21:31:40] <Jymmm> CaptHindsight: It is I, no promises on the latter ;)
[21:32:31] -!- Patang has joined #linuxcnc
[21:33:58] <enleth> _unreal_: high-level comments, especially from people familliar with LinuxCNC's motion planner and HAL. I assumed this is obvious when asking for "any thoughts" after describing a high-level idea dependent on the internals of the motion planner and HAL.
[21:36:20] -!- phiscribe_ has joined #linuxcnc
[21:36:24] <_unreal_> enleth, AGAIN.... WHAT are you asking I've read it multi times now...... your question is not really narrow
[21:39:24] -!- phiscribe has quit [Ping timeout: 272 seconds]
[21:39:43] <_unreal_> I assume you mean you want to setup a TOOL rotation system so you can swap tools. THAT IS NOT an XY setup. but an A rotation style axis generally. unless you want to use some kind of a PICK and PLACE system to pick up a TOOL from a XY matrix style tool holder....
[21:40:01] <_unreal_> SOOO... narrow the scope of WHAT your are asking
[21:40:04] <enleth> _unreal_: jesus, not everything said here has to *be* a narrow question. if you really insist, the question is: "what do you guys think, is that even remotely doable within the LinuxCNC codebase as it is now, or am I hosed"?
[21:40:11] <enleth> _unreal_: no, you completely misunderstood it
[21:40:34] <_unreal_> I may have no argument
[21:40:54] <_unreal_> brb OMG 9:40 putting my 9yo to bed
[21:41:01] <_unreal_> one sec
[21:42:20] <_unreal_> I'm back
[21:42:39] <_unreal_> kids to bed
[21:43:20] <enleth> _unreal_: this is about doing fast moves on a heavy or wobbly machine, by being able to move the tool itself relative to the toolhead, separately from the machine's "regular" axes, with a very limited range of motion but at a potentially much higher speed than the "regular" axes can do
[21:44:02] <_unreal_> What kind of a mchine
[21:44:04] <_unreal_> machine
[21:44:20] <enleth> gantry plotter comes to mind, but this really isn't that important
[21:44:30] <_unreal_> stationary or moving gantry
[21:45:02] <enleth> that's utterly, completely irrelevant
[21:45:17] <enleth> I'm not asking about a particular machine
[21:45:18] <_unreal_> it is important because every moving part ADD'S the error range of play
[21:45:39] <enleth> I'm getting the impression that we're not quite on the same page here
[21:45:56] <_unreal_> fine ok.. hypothetical a plotter with a DUAL X plane
[21:46:03] <veek> anyone familiar with the Aluminium Classification system?
[21:46:16] <_unreal_> I'm having a hard time picturing an XY/XY table
[21:46:28] <enleth> what I'm asking about is a motion control idea/model/concept, how the machine looks makes absolutely zero difference
[21:46:29] <_unreal_> sorry XY/XY flimsy fast plotter
[21:47:46] <_unreal_> veek, are you asking about its grade of duriblity and MOMENT?
[21:47:59] <_unreal_> sorry flex and moment
[21:48:07] <veek> nope the whole 1xxx implies 99%
[21:48:17] <veek> what does the 2nd digit etc imply
[21:48:22] <_unreal_> duriblity lol I've had to much wine and I'm on my first cup :)
[21:48:46] <_unreal_> OHOHHHHHHHHH.... ya that I cant answer
[21:49:14] <enleth> _unreal_: it's probably better if you imagine a VERY heavy machine that would need to slow down a lot to trace a complex toolpath with very small details, like a high amplitude sine wave set diagonally to the axes
[21:49:16] <_unreal_> I'd have to google
[21:50:05] <_unreal_> enleth, ok... microstepping.... on a machine with high backlash
[21:50:09] <enleth> _unreal_: with a dual X/Y stage, one of them very small and right at the toolhead, the machine as a whole could zoom over the toolpath in a straight line, with only the tool itself doing the sine wave
[21:50:13] <enleth> jesus, no
[21:50:13] <veek> _unreal_, https://www.esabna.com
[21:50:16] <enleth> what microstepping
[21:50:18] <enleth> what backlash
[21:50:22] <enleth> completely missing the point
[21:50:26] <_unreal_> veek MSG
[21:50:28] <veek> good explanation my book sucks
[21:51:08] <_unreal_> veek, check msg
[21:51:21] <enleth> _unreal_: I'm sorry, I tried, but I don't think I'm getting anything across now. and my whole question is a long way up in the backlog and no one else is going to read it and comment on it
[21:51:42] <enleth> what a waste of time
[21:51:44] <_unreal_> I'm trying. I'm a marine engineer
[21:52:20] <_unreal_> but the question that I'm reading I've answered as best I can..... as I said its best to narrow your question and build up.......
[21:52:51] <_unreal_> your asking a question that is NOT making sense.
[21:52:54] -!- sector_0 has joined #linuxcnc
[21:52:59] <enleth> the question was about the LinuxCNC software internals and control theory, NOTHING to do with the mechanical implementation
[21:53:25] <_unreal_> linuxcnc is very flexable and can be scripted.......
[21:53:34] <enleth> not at that level, I think
[21:53:46] <enleth> and I know it is, I'm using it
[21:54:22] <_unreal_> if you feel that the lincnc is not capable then you need to take it to a hardware level abstraction layer and use a micro controller to preform automated functions
[21:54:36] <enleth> what
[21:54:49] <enleth> again, what you said has nothing to do with anything

[21:56:29] <enleth> yes, I know where the manual is, this is irrelevant
[21:57:31] <_unreal_> At this point I'm sorry I give up... I dont know what your desired answer is between what your writing and thinking sorry.

[22:00:39] <enleth> _unreal_: you're a marine engineer, right? so try to imagine someone asked you to draw a sine wave - 2m in amplitude, 4m period - with a stick on water, while you're standing at the stern of a 80000 DWT tanker. you're holding the stick in your hands, it's long enough to reach the water. would you rather try to get the whole tanker to strafe left and right by 2m as it's moving forward, or just let the
[22:00:45] <enleth> ship move in a straight line and wave the comparatively lightweight stick with your hands so that the end in the water traces a sine wave?
[22:00:56] -!- phiscribe_ has quit [Ping timeout: 272 seconds]
[22:01:56] -!- dirtyroshi has quit [K-Lined]
[22:01:57] <enleth> the end result would be exactly the same if you held the stick straight and somehow got the ship to move sideways at a 2m amplitude, 2m period, but surely you can see a problem in trying to do that with a tanker
[22:02:54] <enleth> even if you tried using side thrusters, the mass of the ship would just completely dampen that sideways movement, or you'd have to move the whole thing *extremely* slowly
[22:06:57] <enleth> eh, now no one is going to comment anything on what I originally wrote because no one's going to read it anymore
[22:11:23] <enleth> _unreal_: and, yes, I am aware that a line traced in the water with a stick while standing on a big ship's stern is going to disappear right into the ship's wake, let's just assume it doesn't
[22:11:27] <jdh> yes, I think you can do it. write your own kins for it
[22:11:48] <_unreal_> https://pastebin.com
[22:11:52] <_unreal_> fuck
[22:19:04] <enleth> jdh: OK, so the way I see it, I'd define the "extra" axes with proper MAX_ACCELERATION set, assume some sort of convention in the custom kins as to which axes are parallel to each other, then use MAX_ACCELERATION to figure out where to split the FFT of the toolpath among parallel axis pairs and feed them DTF-ed components of the path
[22:19:19] <enleth> jdh: does that make any sense?
[22:19:44] <enleth> er, wait
[22:20:40] <enleth> *split the FFT *feed them inverse-FFT-ed components

[23:50:39] <enleth> pcw_home: oh, that's nice to know. have you heard of anyone using an actual extra linear stage at the tool?
[23:52:50] <enleth> unless there's something fundamentally wrong with that idea, I imagine it would do wonders to really big plasma/waterjet cutters e.g. for making lots of small holes
[23:54:47] <pcw_home> Not other than the piezo-electric devices (note that they are _very_ stiff so don't increase the mechanical impedance and the tool much)
[23:56:23] <pcw_home> for devices with negligible cutting loads like plasma I think the Z axis is already as light as possible
[23:56:35] -!- cpresser has quit [Ping timeout: 240 seconds]
