[00:02:28] <CaptHindsight> yeah, I was trying to get away from having to program yet something else
[00:04:44] <andypugh> CaptHindsight: As has been mentioned, this is standard behaviour for a VFD. An some VFDs can drive brushed or brushless motors and servos too. I am thinking especially of the Control Techniques Unidrive.
[00:05:40] <FloppyDisk> Plus, some of them have encoder feedback (I think) for really const motion. The CTC (control techniques) is good stuff.
[00:06:52] <CaptHindsight> andypugh: what I don't see is how to easily set the ramp along with the speed

[00:07:54] <andypugh> My cheap VFD has all sorts of options that I have ignored. They looked like what you describe, but to be honest I didn’t pay much attention.
[00:09:11] <FloppyDisk> Some of the drives have some inputs where you 'might' be able to run in another poteniometer for the ramp settings. How you 'see' it is another issue.

[00:43:02] <CaptHindsight> without feedback it easy
[00:44:39] <enleth> OK, so nanotec is out, they make drives with integrated position/velocity control but no separate control boards

[07:41:53] <trentster> hey all some advice please, busy redesigning my machine
https://s3.amazonaws.com/f.cl.ly/items/1G2y2y3f3d1B0Y3s422w/cnc%20machine%20trentmill%20v15.png
[07:43:31] <trentster> got Hiwin Linear profile rails coming and new Z axis designed, I want some feedback regarding the bed, I was thining of using the extrusion beams that make up the machine as part of the T slot bed. So raise them so the top t slots can be accessed - is this a bad idea?
[07:44:14] <archivist> bed design depends on work you are doing
[07:47:26] <trentster> archivist: the machine is solid enough for my uses its great for hard woods and aluminium cutting, its max IPM speed is limited because of the current rails and work holding is a PITA , I would like to improve on that.
[07:47:41] <trentster> I would also like to offer a design to other folks for a semi cost effective build
[07:48:44] <archivist> tslots are good for bolting random stuff onto, others may want a vacuum bed
[07:49:15] <archivist> one of those "depends"
[07:49:16] <ReadError> trentster confused as to what the question is
[07:50:27] <trentster> archivist: I am looking for a solution that does not involve a dedicated t-slot bed purchase one that incorporates structural extrusions and leverages their top slots
[07:51:44] <archivist> trouble with all extrusion designs is missing the step of making the cutting plane flat
[07:52:34] <trentster> ReadError:
https://monosnap.com/file/DMVTT3HRKQXxsgJYQHoGt1hDMSjGeW this is what I mean
[07:52:38] <ReadError> hard to run a bed leveling path?
[07:52:46] -!- vapula [vapula!~rolland@195.25.189.2] has joined #linuxcnc
[07:53:16] <archivist> ReadError, but the rails are mounted on the bent extrusions :)
[07:53:22] <trentster> the possible problem with that is it may deflect the bed frame when tightening down
[07:53:31] <ReadError> yea tslot doesnt come straight always
[07:53:39] <ReadError> or the same length ;(
[07:53:52] <CaptHindsight> people assume that t-slot is flat or not curved
[07:53:54] <ReadError> last build I had to spend a bit of time squaring up the ends and 'matching'
[07:54:26] <archivist> there is a fundamental problem with extrusions, the speed they are extruded and cooled makes them non flat/straight
[07:55:02] <ReadError> trentster if you go w/ a MDF or PVC bed, you can just run a leveling toolpath
[07:55:06] <archivist> talk to an extrusion salesman he should tell you this
[07:55:08] <CaptHindsight> Pacific Bearing machines their t-slot on 3 sides simultaneously when used for positioners
[07:55:08] <trentster> The other issue I am having is its darn hard to attach the wooden table / spoilboard to the t-slot nuts as they are trapped in the extrusion squized between the front and back flat plate
[07:55:11] <ReadError> and cut some slots
[07:56:06] <archivist> ReadError, that path will be as unstraight as the rails the gantry is on
[07:56:25] <trentster> ReadError: I am currently using plywood bed and running a levelling path on it - no good?
[07:56:35] <CaptHindsight> http://www.pbclinear.com/Download/Document/SIMO-Process-Overview.pdf
[07:56:35] <ReadError> archivist yea but wouldnt it be compensated for by leveling?
[07:56:45] <ReadError> when you actually go to cut something
[07:57:09] <archivist> no the cutter path itself is controlled by its rails
[07:57:26] <archivist> the rail munting needs to be right when made
[07:57:35] <archivist> mounting
[07:57:41] <ReadError> on the bright side, the hiwin rails will be straight
[07:57:44] <CaptHindsight> t-slot is not flat or straight and also twists
[07:57:52] <archivist> ReadError, erm no
[07:57:52] <ReadError> and theres some slack in mounting them
[07:58:01] <trentster> archivist: if extrusion is not flat enough for you whats the solution for you? steel machined flat?
[07:58:28] <CaptHindsight> or at least solid aluminum
[07:58:52] <archivist> they curve due to the hardening process, they expect the rails to be mounted on a substrate that holds them flat
[07:59:33] <archivist> anyway depends on the required accuracy level
[08:00:30] <trentster> ReadError: I should have probably started with hiwin rails for the Y axis instead of the for the X (Gantry) axis as its a longer run an driven with a single ballscrew - right?
[08:00:39] <swarfer> looked at openbuilds.com extrusions?
[08:01:00] <swarfer> they limit the production length to keep them straight
[08:01:37] <archivist> swarfer, it is how they slump between extruder and the conveyor
[08:01:59] <archivist> well before they get to any substantial length
[08:02:40] <trentster> wow I had no idea that elu extrusion was not perfectly flat, hmmm interesting
[08:02:42] <ReadError> swarfer those were pretty deadnuts straight
[08:02:47] <archivist> there should be a straightness spec on any extruders site
[08:02:50] <ReadError> length was a bit variable
[08:03:05] <ReadError> and the ends not square
[08:03:09] <ReadError> but both easy fix

[08:06:44] <CaptHindsight> the design merry go round
[08:07:50] <CaptHindsight> after the machine is built he can bend and twist it to see what he should have done better
[08:07:55] <archivist> no "one right answer"
[08:08:25] <archivist> get an FEA package to waste less metal
[08:08:36] <CaptHindsight> or he might not even care about how much it flexes
[08:09:05] <trentster> So guys I have a flat sheet of aluminium the same size as the table, its 6mm thick - do you think I should use it as a table first surface and attach mdf spoilboard to it?
[08:09:22] <archivist> I think single ballscrew on a gantry defines dont care about twist
[08:09:29] <CaptHindsight> he can put the 16mm x 4mm steel bar in all the open slot to stiffen it up
[08:09:58] <ReadError> dont some people put torsion rods in
[08:10:08] <ReadError> to adjust warp, thought I saw that somewhere
[08:10:16] <CaptHindsight> I make drum skins out of 6mm aluminum plate :)
[08:10:42] <trentster> CaptHindsight: so is that a no - dont use it as a table first surface?
[08:11:10] <CaptHindsight> it will bend from a serious stare
[08:11:42] <trentster> surel 6mm plate plus a mdf table is better than a mdf table alone?
[08:11:49] <CaptHindsight> look for a used steel surface/setup plate
[08:12:09] <archivist> cast iron :)
[08:12:15] <trentster> the chance of me finding that in AU is probably close to zero
[08:12:18] <CaptHindsight> yeah ^
[08:13:00] <archivist> I should go and oil mine for winter
[08:14:10] <CaptHindsight> cast iron plate + pay a shop to surface grind it for you
[08:14:19] <trentster> archivist: your opinion on the alu plate - do I use it or not ( I am aware steel or cast iron would be better) but I have this to use
[08:14:54] <CaptHindsight> it's better than nothing
[08:14:59] <trentster> CaptHindsight: in Au that will probably cost $2k to do

[08:20:13] <trentster> archivist: yeah - I am not building a mill
[08:21:04] <trentster> its a CNC router - the main intention is to come up with a design that does the best compromise between high end and medium end for hobbyists and home fabricators at a price they can jump in.
[08:21:26] <archivist> but if you look at a pro wood machine you will see the rigidity taken care of, google Wadkin
[08:21:52] <trentster> So I guess I am saying pretend I gave each of you $3k and you had to come up with the best possible machine for the buck - what would you come up with.

[08:29:21] <trentster> ok - I understand.

[09:41:13] <enleth> trentster: hobby woodworkers are more likely to use hand tools and traditional methods of manufacture, but for metalworking even a hobbyist needs a machine tool so the market is bigger
[09:41:35] <enleth> and the barrier to entry for CNC is much lower that way
[09:41:46] <enleth> a small CNC wood router? who needs that?
[09:43:45] <enleth> I mean, a bunch of people do, but there are hardly any mid-sized machines - between pathetic midget routers on kickstarter and actual production stuff the size of this latter Wadkin
[09:45:25] <enleth> trentster: a friend tried to build a mid-sized router using T-slot extruded aluminum, it was expensive (on paper, he used leftovers he got at work so didn't have to pay for them) and still wobbly as fuck
[09:46:13] <enleth> Some people weld them from steel tubing and that apparently works and the result is a working, useful machine

[14:41:38] <Frank__> there are some news in my build, the structure came back home, after beeing machined. they took 1 and a half month to do something that take them 3 days.. or less
[14:41:39] <Frank__> omg
[14:42:02] <Frank__> they bad news are that i have to do all the drilling T_T
[14:42:40] <Frank__> does someone have any advise to drill the holes with precision for the hiwin linear guides?
[14:45:11] <max12345> can I change the orientation of the preview?

[14:48:04] <Frank__> i assumed so, like marking with the rail clamped down, i have a machined reference edge
[14:48:10] <Frank__> that one helps to for one side

[15:29:55] <maxcnc> Hi ;-)
[15:32:35] <maxcnc> Frank__: how is it is it building up
[15:33:00] <Frank__> hello!
[15:33:02] <Frank__> how are u
[15:33:07] <Frank__> yes, machine arrived
[15:33:11] <maxcnc> finished for today
[15:33:23] <Frank__> now i have to drill everythign
[15:33:28] <Frank__> a pain in the ass
[15:33:32] <Frank__> +100 holes
[15:33:38] <maxcnc> dont brake so many bits
[15:33:39] <ReadError> why wouldnt they drill?
[15:33:51] <Frank__> idk, for accumulated error i think
[15:33:55] <Frank__> of their machine
[15:34:37] <Frank__> they gave me the machine with rough surfaces, i think they use the method of stripping steel with an insert
[15:34:43] <Frank__> thats low quality right?
[15:34:49] <maxcnc> remodifiing ais always cool and painfull
[15:35:05] <maxcnc> but in the end its like you want it
[15:35:16] <Frank__> i am building from the ground up thou
[15:35:32] <maxcnc> the servo stepper mixure
[15:35:32] <Frank__> wood router
[15:35:35] <trentster> enleth: thanks for your input - it makes a lot of sense
[15:35:50] <Frank__> actually, i finally bought 4 servos
[15:35:51] <Frank__> all 1kw
[15:37:06] <Frank__> do u know how can i check flatness of the machined surface?
[15:37:21] <archivist> a good level
[15:37:34] <archivist> a straight edge
[15:37:35] <Frank__> i have a starret 8 inch
[15:38:15] <Frank__> 98-8 starret
[15:38:40] <archivist> I used something similar for my build
[15:39:12] <Frank__> graduations of 0.005 per foot
[15:39:14] <Frank__> is enough?
[15:39:26] <Frank__> 0.42mm x meter
[15:39:29] <archivist> you got enough 0 there?
[15:39:43] <archivist> 8in should be better
[15:39:44] <Frank__> i really dont know!
[15:40:01] <Frank__> ?
[15:40:08] <Frank__> 8 in of what
[15:41:10] <archivist> I am waiting for starretts site
[15:41:23] <archivist> effin slow
[15:41:41] <Frank__> really? for me it loads fast
[15:42:13] <Frank__> after the 8 in comes the 12 in
[15:42:20] <Frank__> but it was kind of expensive
[15:43:23] <archivist> starrett is over priced for what they are
[15:43:40] <archivist> 5 thou per ft is not that good
[15:43:53] <Frank__> shame
[15:43:58] <maxcnc> Frank__: keep the budget
[15:43:59] <Frank__> :/
[15:44:20] <archivist> you may be able to read it to a better accuracy with care
[15:44:34] <Frank__> actually i dont really know how to use it
[15:45:02] <archivist> I could send you one except for the postage cost
[15:45:34] <Frank__> if it moves 1 line from the center, that means that a foot from the level its deviated about 0.005inch?
[15:45:51] <Frank__> its fine arch, im not from the states anyway
[15:45:53] <archivist> something like that
[15:46:03] <archivist> I know where you are
[15:46:22] <Frank__> wow nice memory haaha
[15:47:20] <Frank__> so if it doesnt move across the machined surface its supposed to be flat?
[15:47:47] <archivist> there are many other level makers, second hand is generally ok as you can easily adjust them
[15:48:15] <archivist> yes the bubble should remain central
[15:48:52] <Frank__> and if it moves its really bad, having into account that the level is not very very precise right?
[15:49:36] <archivist> adjust bed/rails/whatever till it remains central
[15:51:10] <archivist> so first adjust frame, then rail on side of frame

[15:58:23] <Frank__> if theres still some movement on the level can it be "repaired" or fixed with some shiming?
[15:58:51] <archivist> I cannot know without seeing
[15:59:01] <archivist> but usually yes
[15:59:21] <archivist> shimming/filing/scraping
[15:59:31] <Frank__> its not really super duper heavy frame, and the 6*4in main beams may move alittle i can play with that too, i have 6 legs to set
[15:59:46] <archivist> even adjustable feet under the frame
[15:59:51] <Frank__> exactly
[16:00:42] <archivist> and you may(will) find just putting a weight on will move the bubble
[16:00:55] <Frank__> so its kind of useless to check flatness now right? with the frame not properly stand
[16:01:13] <Frank__> i am cleaning with wire know brush to paint it
[16:01:16] <archivist> I hope you are on a concrete floor :)
[16:01:19] <Frank__> then holes, then alignament..
[16:01:24] <Frank__> yes
[16:01:35] <Frank__> idk how thick it is, but its concrete
[16:01:52] <Frank__> i was thinkin on making some concrete cubes to make it a little more tall
[16:01:52] <archivist> get frame level, before you use the level to set the rail level to drill
[16:02:24] <Frank__> the hole frame without the Bolts that make the legs its 25cm
[16:02:30] <Frank__> 11 inch
[16:02:33] <Frank__> aprox
[16:02:50] <Frank__> ok
[16:02:58] <Frank__> so i shouldnt panic yet
[16:02:59] <Frank__> ahahah
[16:03:20] <archivist> panic....dont panic, dont panic

[18:55:07] <andypugh> Right, time to shift a 750kg lathe from one side of the workshop to the other so that I can try to figure out what is broken in the drivetrain. I doubt I can even lift the variator when I get to it.
[18:57:18] <skunkworks> andypugh, so that is why the vfd is tripping?
[18:57:29] <andypugh> I am hoping so.
[18:57:46] <andypugh> The drivetrain is locked solid at the moment.
[18:57:51] <skunkworks> ah
[18:58:06] <andypugh> I just hope it is the Variator and not the gearbox.

[19:07:17] <aventtini6> hello guys
[19:08:14] <aventtini6> PCW is on Today ?
[19:09:49] <roycroft> my contractor just called
[19:09:58] <roycroft> he asked me how heavy the vault is that he's trying to install
[19:10:25] <roycroft> his biggest backhoe on site can lift 4750kg
[19:10:37] <roycroft> er, it can lift 2725kg
[19:10:43] <roycroft> the vault weighs 4750kg
[19:10:48] <roycroft> he's having trouble lifting it
[19:11:30] <roycroft> i suggested he bring in heavier equipment
[19:11:37] <roycroft> he's not happy about that
[19:11:59] <roycroft> but i pointed out that the weights of the vaults are stipulated in the bid specs
[19:13:10] <FloppyDisk> Just use 2 backhoes...
[19:18:50] <thesaint> roycroft, vault as in strong room..?
[19:19:01] <roycroft> underground utility vault
[19:19:06] <thesaint> ok..
[19:19:11] <roycroft> i'm installing an extension to a fiber ring
[19:19:28] <thesaint> cool.
[19:19:38] <roycroft> most of the vaults are relatively small
[19:19:54] <roycroft> but there's one section at the end of this loop extension that we can't complete yet
[19:19:56] <thesaint> just not this one?
[19:20:13] <roycroft> the city has to acquire a piece of property so we can have a right of way
[19:20:33] <roycroft> the run from the edge of the property back to my main loop is about 400m
[19:21:07] <roycroft> so i'm installing a giant vault at the edge of the property, and we'll store that 400m of fiber in it until the city acquires the land, at which point we can extend and close the loop
[19:21:22] <roycroft> it's kind of weird
[19:21:32] <roycroft> but it saves having to splice there
[19:22:51] <thesaint> interesting..
[19:23:20] <roycroft> the cost is pretty much a wash
[19:23:36] <roycroft> oversizing the vault cost us about $2000 more than a standard vault
[19:23:48] <roycroft> splicing 288 strands of fiber would cost around $2000
[19:23:58] <roycroft> but this way i have one less splice point
[19:24:04] <roycroft> and therefore one less point of failure
[19:24:09] <roycroft> and less loss
[19:24:36] <roycroft> we knew 15 years ago that we'd be installing this fiber ring
[19:24:49] <roycroft> and the city had been planning on acquiring the property for years before then
[19:24:51] -!- AphelionZ has quit []
[19:24:53] <roycroft> it's undeveloped property
[19:25:05] <roycroft> i'm a little annoyed that they still don't have it
[19:25:07] <roycroft> but oh well
[19:26:32] <thesaint> another ngcgui question - can you run features together? how would i add them and save them for a job? is that possible?
[19:26:42] <andypugh> And.. now I am feeling smug that I made the lathe moving frame. It took most of the time to move other stuff out of the way.
[19:27:18] <roycroft> that is generally the most time-consuming task
[19:27:43] <thesaint> andypugh, you make it from wood or metal?
[19:28:13] <andypugh> Metal.
[19:28:31] <thesaint> andypugh, please post of quick picture if you can be bothered..
[19:28:55] <andypugh> Pics 7 and 8 here:

[19:29:52] <andypugh> It’s modular (should work for the mill too) and lets me assemble it round the lathe, then jack the lathe up a few mm above the floor
[19:30:56] <thesaint> andypugh, like it, how you jacking it up? toe jacks?
[19:31:17] <thesaint> andypugh, and those straps that go under it work ok?

[19:41:19] <aventtini6> i have one of machine dead from mechancial problems
[19:41:35] <aventtini6> and i got another one but no mesa
[19:41:42] <thesaint> does anyone know if you can run ngcgui features one after the other automatically? like the program for a full part..?
[19:42:04] <aventtini6> no sorry
[19:42:08] <thesaint> rather than one after the other manually?
[19:42:23] <andypugh> thesaint: I believe that is one of the advantages of NGCGui over (for example) my Lathe macros.
[19:42:43] <Frank__> its like u are missing one arm right? haha
[19:43:56] <thesaint> andypugh, would be very useful and I would like to know how.... at the moment i have them working but have to run one after the other. cant seem to see how you would add them together...
[19:44:28] <andypugh> I think that JT-Shop knows how
[19:45:21] <Frank__> guys, i asked earlier but maybe some of you know some other advise, i want to check flatness of the machined structure that arrived 2 days ago, i have a starret 98-8 8 inch 0.005 per foot

[19:46:54] <thesaint> Frank__, you need actual values or just an idea it is pretty good?
[19:47:11] <Frank__> i need to know that the hiwin linear guides will work nicely
[19:47:16] <Frank__> i will be routing wood
[19:47:27] <ssi> do you have the rails already?
[19:47:30] <Frank__> yes
[19:47:32] <andypugh> They use a straight-edge, two accurate blocks and a dial indicator-like device
[19:47:35] <ssi> use them as a straightedge
[19:47:37] <ssi> they're quite straight
[19:47:41] <Frank__> mine dont
[19:47:43] <Frank__> haha
[19:47:51] <Frank__> the move pretty easily
[19:47:55] <Frank__> they are 2.4mts
[19:48:01] <ssi> even on edge?
[19:48:12] <ssi> how big of a machine are we talking?
[19:48:39] <aventtini6> straight edge is the way
[19:48:44] <Frank__> 8 feet aprox
[19:48:50] <Frank__> :D
[19:48:53] <aventtini6> my longest is 3 meter
[19:49:00] <Frank__> how much
[19:49:08] <andypugh> If you have the rails then you can test by putting the straight-edge at one end and measuring the angle with a very accurate spirit level. Then do the same at the other end and the middle.
[19:49:38] <thesaint> Frank__, andys method is best but if you can get a large straigh edge and a mono chromatic light you can get a good idea that should suit your purpose...
[19:49:40] <Frank__> how much is very accurate? i have a starret 68
[19:49:51] <Frank__> sry 98-8 8 inch with 0.005 grade per foot
[19:50:02] <ssi> how accurate do you need to be ? :P
[19:50:11] <Frank__> enough for the linear guide
[19:50:15] <ssi> which is?
[19:50:29] <andypugh> That is probably good enough for a wood machine.
[19:50:42] <thesaint> ssi, no light shining through is good enough..
[19:50:44] <Frank__> i've seen manual specs but they dont account for linear flatness, they call for parallelism bet. rails and height bet. them
[19:51:06] <ssi> perhaps because linear flatness over a long span isn't critical
[19:51:12] <Jymmm> looking for bowing?
[19:51:12] <Frank__> the machining process they did was removing material with an insert
[19:51:18] <ssi> you're primarily concerned about binding between trucks
[19:51:23] <andypugh> That will be because the flatness limit very much depends on what is fastened to the sliders.
[19:51:24] <Frank__> leaving little marks accros the guide rail
[19:51:38] <thesaint> Frank__, suck it and see?
[19:52:04] <Frank__> yes im concernerd about binding and longevity of rails

[20:08:56] <Magnifikus> we get isopropanol for free so thats the thing of choice
[20:09:57] <CaptHindsight> up to what vapor pressure you want
[20:10:32] <CaptHindsight> IPA evaporates very quickly, water is much slower (comparatively)
[20:11:11] <Magnifikus> thought about 1,5 bar on the coolant and dunno 2 on the air?

[20:13:00] <CaptHindsight> getting the IPA into the cutting edge might take some clever nozzle design
[20:13:20] <CaptHindsight> or just flood it
[20:13:30] <Magnifikus> we did that until now
[20:13:56] <CaptHindsight> like to burn well
[20:14:04] <Magnifikus> yeah
[20:14:16] <Magnifikus> also that wont get the chips away
[20:14:33] <Magnifikus> so you end i chips -> grey mass
[20:14:33] <CaptHindsight> so safety vs cooling performance might be an issue
[20:14:49] <Magnifikus> so better professional stuff with higher flaming point
[20:15:27] <CaptHindsight> IPA + water + oil + surfactant
[20:16:20] <CaptHindsight> I don't cut fast enough to need more than water + oil + surfactant

[20:18:09] <Magnifikus> thats insane..
[20:18:21] <CaptHindsight> like vodka, brandy and whiskey etc

[20:21:30] <thesaint> Magnifikus, they do..
[20:22:28] <thesaint> Magnifikus, i have a similar machine, just thinking about cooling solutions now..
[20:22:51] <Magnifikus> we got just an old isel gantry thingy with kress ontop :)
[20:22:56] <thesaint> would like to use a similar solution.
[20:23:09] <Magnifikus> but im sick of pouring liters of IPA into the workpiece
[20:23:29] <thesaint> because of the cost? what is the problem?
[20:23:45] <Magnifikus> smell and chips stay on the mill
[20:23:58] <Magnifikus> also we can get it for free but only in 500ml thingies :D
[20:24:18] <Magnifikus> and cuties at the chemical supply start to ask
[20:24:19] <thesaint> Magnifikus, ok...
[20:25:01] <Magnifikus> manual flooding is not really the best way or im wrong?
[20:25:17] <Magnifikus> flood cooling is no option because the machine is not made for that
[20:25:43] <Magnifikus> so minimal cooling seems to be the best for aluminium imho
[20:26:04] <Magnifikus> so the article states its cool for non sparking materials
[20:26:19] <Magnifikus> i saw sparks when a tool broke :D
[20:27:27] <thesaint> Magnifikus, well you could simply test what happens when it ignites. i would do that first of all.. just out of curiousity.
[20:27:34] <thesaint> of course :-)
[20:27:44] <Magnifikus> good idea
[20:28:04] <thesaint> spray some, light it, you get the worst case scenariaio.
[20:28:08] <Magnifikus> and because it evaporates fast it should be much safer than an IPA flooded part
[20:28:23] <thesaint> but if datron are using it i think it would be good...
[20:28:31] <Jymmm> BEER FLOOD?! That's alcohol abuse!!!
[20:28:36] <Magnifikus> hehe
[20:28:37] <thesaint> lol..
[20:28:57] <Magnifikus> only cheap johnny walker!
[20:29:35] <Magnifikus> will try something like 30% water 70% ipa and do a burnin test ^^
[20:32:06] <thesaint> Magnifikus, i think the idea is to use no water...
[20:32:53] <thesaint> i dont know but i would think you need some sort of ventilation or recovery process, the solvent has to go somewhere...
[20:33:13] <Magnifikus> if you use 50-100ml an hour
[20:33:16] <Magnifikus> its not alot

[21:07:33] <nos> I just figured something out!
[21:08:23] <nos> Chips aren't the hottest right at the cutting edge, but a little distance from the edge. This is because of the phase transition from liquid to solid, which releases heat.
[21:09:34] <nos> So a chip just off the cutting edge has liquid phase, and then beings to re-crystallize.
[21:09:49] <SpeedEvil> err...
[21:09:54] <SpeedEvil> chips are never ever liquid.
[21:10:01] <SpeedEvil> Unless you're doing something very, very odd
[21:10:23] <SpeedEvil> yielding does not mean it is not a liquid
[21:10:34] <SpeedEvil> is a
[21:10:41] <Magnifikus> depends i tried teflon yesterday with a not so sharp...
[21:10:52] <Magnifikus> that was pretty sure liquid
[21:11:20] <nos> I don't think the metal has to be completely in the liquid phase for the effect to occur.
[21:12:10] <nos> (BTW I used to reg here a few months ago under the nick ganzuul.)
[21:12:21] <Magnifikus> https://www.youtube.com/watch?v=mRuSYQ5Npek
[21:12:51] <Magnifikus> that does not look liquid :)
[21:13:00] <nos> Magnifikus: That video is engraved in the dome of my skull.

[21:24:00] <XXCoder> new old stock, yeah I still wonder how they did that video.
[21:26:03] <thesaint> JT-Shop, right... I think I get the idea, so you would put it all together as one new .ngc as per your requirement? thanks!
[21:28:38] <XXCoder> nos: there is videos that show tool cutting inside lathe,.
[21:28:52] <XXCoder> apparently they use flash/fps combo as well and half cut stock
[21:28:58] <XXCoder> amazing.
[21:29:24] <XXCoder> lets see if can find it
[21:30:49] <XXCoder> bah cant
[21:32:27] <JT-Shop> thesaint: yes, you move the tabs to the order you want then pick finalize

[21:33:01] <JT-Shop> making sure you create each feature before finalize
[21:33:08] <thesaint> JT-Shop, aah...
[21:33:45] <thesaint> do you pick finalise on each of the tabs or only once?
[21:34:00] <thesaint> unless i missed it that is not clear in the docs..
[21:34:45] <JT-Shop> yea finalize is what it means and the docs are a bit terse on the actual use of ngcgui :(
[21:35:30] <thesaint> JT-Shop, got it... sweet!!!

[21:36:49] <thesaint> JT-Shop, 3 days in and i can almost make a part :-) lol... - happy!
[21:37:26] <thesaint> JT-Shop, but now i can make a part quickly and easily - well worth the effort :-)

[21:54:31] <Roguish> JT-Shop: hey, with your vfd on the BP, are you (can you) rigid tap?
[21:56:21] <JT-Shop> yes, and it was made easy by having a kwik switch spindle
[21:56:27] <JT-Shop> no draw bar in the way
[21:56:47] <Roguish> so, the spindle will reverse quickly enough?
[21:57:07] <JT-Shop> the axis is fast enough to keep up with the spindle
[21:57:29] <JT-Shop> you can turn the spindle by hand and the axis will follow
[21:58:03] <Roguish> encoder on the spindle? counts per rev?
[21:58:39] <FloppyDisk> I read andyp said the Z axis follows the spindle encoder, so Z must keep up..
[22:01:21] <Roguish> JT-Shop, is the vfd run off the rpc 3 phase?
[22:01:33] <Roguish> or run off single phase ?
[22:04:36] <JT-Shop> the vfd is an automation direct gs2 single phase in 3 phase out and controlled with the gs2 component
[22:05:26] <Roguish> ok. so no rpc for the vfd, and it is cool with rigid tapping. great!!
[22:05:56] <Roguish> the AD vfd's are nice. good value.

[22:10:14] <JT-Shop> yea up to 3hp single in 3 out is common
[22:11:15] <JT-Shop> you need the braking resistor for tapping
[22:11:28] <FloppyDisk> JT should get a rep commission for selling AD...
[22:11:33] <Roguish> I see that on the AD site. my spindle is 4 hp. series II bp.
[22:14:36] <FloppyDisk> I went w/ the cheap braking resistor:

[22:53:25] <CaptHindsight> AB panelink for only $2995
[22:53:35] <Magnifikus> cause the software they use is from kinco china
[22:53:53] <Magnifikus> "relabeled for quality" :D
[22:54:38] <jdh> value added relabeling
[22:54:50] <CaptHindsight> not bad if the warranty is handled through LA vs China
[22:55:24] <CaptHindsight> good fit for a low cost small custom machine with a 1 year warranty
[22:55:49] <Magnifikus> okay but if you can get 2 for the price of 1
[22:56:19] <CaptHindsight> wish there was a Linux version
[22:57:08] <Magnifikus> looks like 128mb flash + 64mb ram
[22:57:14] <Magnifikus> some arm inside
[22:57:37] <CaptHindsight> the hardware is easy and cheap to make
[22:58:01] <CaptHindsight> it's the interface software where Linux falls short
[22:59:00] <Magnifikus> if you can get a serial protocol running for the hmi
[22:59:08] <Magnifikus> shouldnt be too hard to interface with linux
[22:59:15] <Magnifikus> even telnet
[22:59:49] <CaptHindsight> just not enough interested developers
[23:00:20] <FloppyDisk> You might be able to download the software

[23:01:22] <CaptHindsight> yes, you can download the 300mb zip of the software
[23:01:25] <Magnifikus> linux developers dont care for nice guis
[23:01:41] <Magnifikus> only the shitty ones making ubuntu unity
[23:01:55] <Magnifikus> that ends in funny security situations :D
[23:02:12] <Magnifikus> and an strange gui
