Back
[00:00:37] <minibnz> i think i just kicked a goal.. two days of pulling it apart putting it baack together again... has stressed me out a little... all i did was change the gears in the head but that required me to crack the joint.. i just did it again and this time it looks good so far..
[00:01:38] <minibnz> i have the column and bed at 90' and when i set a square against a length of tool steel in the chuck i can no longer see the gap that i could before.. going to setup the dial and see what i can see..
[00:02:45] <minibnz> and everyone use oh my god... cuz "oh your god" is blaming other peoples imaginary freind for thier problems.. this way they are sorta owning the problem. .blaming their own imaginary friend..
[00:05:44] <CaptHindsight> oh my gawd!
[00:14:35] <minibnz> CaptHindsight blames his dried vegetable skin not his imaginary friend :)
[00:14:44] <minibnz> or is that spelt gord?
[00:54:41] <tiwake> have a picture of a few parts I anodized... http://tiwake.com/DSCN0081.JPG
[00:55:47] <Ralith> nice
[00:56:27] <tiwake> I've anodized a little over 100 of those parts now, getting the hang of it
[00:57:02] <tiwake> with the blue and purple I also did a slow dip, so that one end is lighter in color than the other end
[00:57:08] <tiwake> looks really cool
[01:05:13] <tiwake> http://tiwake.com/DSCN0094.JPG
[01:05:29] <tiwake> the orange came out great
[01:05:46] <tiwake> the red I have for some reason likes to wipe off the parts... donno... its weird
[01:22:43] <minibnz> does it need a different prep?
[01:28:47] <tiwake> it shouldent
[01:29:02] <minibnz> was thinking maybe from a different manufacturer
[01:29:18] <tiwake> no, all the dye is from casswell
[01:29:51] <archivist> pigments can have different particle sizes
[01:30:11] <tiwake> but only the red will "rub off" when it is touched... the other colors don't do that
[01:30:25] <minibnz> oh that was a mamoth effort.. i think i have the thing trammed.. so i went to test it but the mill would not spin... in all my futzing around the spade terminals on the motor had come undone.. in fixing that i took the chance to replace a fig8 cable with sheilded cable to keep out some noise on my servo speed control line.. and then decided to add a better switch that allows me to power off the rc servo when its in manual mode, lets me t
[01:30:26] <minibnz> urn the speed down while the CNC control is enabled.. now i think i am ready to test a fly cut and see how well its trammed.. or if i have to start all over yet again...
[01:30:32] <archivist> is your process not producing large enough pores
[01:30:51] <tiwake> possibly... donno, I havent had problems really though
[01:30:56] <minibnz> oh i see your theory there..
[01:31:09] <tiwake> other than red
[01:31:24] <tiwake> and the red works if its not touched
[01:31:55] <archivist> if it rubs off it had not soaked in
[01:32:16] <archivist> or dried/ been fixed
[01:36:09] <tiwake> its definitely in... at least somewhat... rinsing the parts off does not change the color
[01:50:27] <tiwake> https://derpibooru.org/1085235
[02:18:08] <Deejay> moin
[02:50:21] <minibnz> just checked the tramming of the mill and its not perfect but i think it might do.. with the column square at 90' there is 0.1mm difference over 100mm travel that could be from the HSS bar i have int he chuck not being perfect.. so i think the head is out by a tiny tiny fraction of a degree between the post and the spindle..
[02:51:20] <minibnz> that will be ok for now.. but when i start drilling 0.25mm holes ina printer nozzle i will have to be careful.. not that my .25mm drill is any where that long so i probably wont see that.
[02:52:06] <minibnz> at the momtent the fly cutter makes nice cross hatch patterns..
[03:15:05] <AmsterdamJoe> hello
[03:15:09] <AmsterdamJoe> im here
[03:36:28] <Akex_> Hy all, can use smoothie board with linuxcnc ?
[03:38:34] <archivist> not really
[03:41:17] <archivist> not enough ram on board to replace the current firmware with linuxcnc
[03:43:54] <Ralith> archivist: it couldn't be used in the way mesa cards are?
[03:45:02] <archivist> its comms is usb!
[03:45:51] <archivist> someone would need to rewrite its firmware
[03:46:31] <minibnz> the way the smoothie is used with printers is you send it gcodes. its firmware does all the movements.. you can try and use the printer firmware but you will find that 3d printers dont support the entire gcode set so you would need to add support for things like arcs.
[03:48:00] <minibnz> there will be many other differences im not sure what will actually effect you.. i am planning on using my 3d printer as a base for a laser cutter. its using the RAMPS board and it lacked support for spindle controls so i hacked in my own code to enable my laser power supply and set the modulation and power etc..
[03:49:08] <archivist> stuff coming out of the reprap world seems to have ignored what went before them
[03:49:09] <minibnz> had to add support for G3 G4 G5.. arcs are going to be the big problem when i start cutting complex shapes but i might make another instance of linuxcnc for the cutter and build its own frame.
[03:49:40] <minibnz> i think it was more a case of milling and cutting kinmatics not really suiting 3d printing.
[03:50:00] <archivist> nah they ignore that as well
[03:51:55] <minibnz> the needed a lot of extra controls like flow rate heat controls so i can sorta see why they started again.. the cost of mesa cards are a bit much when the goal is a $500 machine. the arduino made sense when they started
[03:52:48] <minibnz> i have troubles writing gcodes for arcs so the firmware is going to be hell.
[03:55:29] <minibnz> i really dont know why they havent don support for arcs maybe its too much for the arduino.. maybe the smoothie board has more support
[04:03:21] <AmsterdamJoe> allways been a fan of x86. I don't know why one would want to reduce the instruction set (like ARM in Arduino)
[04:03:54] <archivist> it is AVR not ARM
[04:04:42] <minibnz> speed. less instructions means you need to query the instruction less to work out what it needs to do. and arduino started off with AVR chips now they also come in ARM varietys but arduino does not = ARM
[04:05:17] <AmsterdamJoe> oh, lets say reduced instruction set RISC processors
[04:05:24] <minibnz> and if there is any reduction in gcode instructions its due to space and processing power requirements.
[04:05:54] <AmsterdamJoe> For me personally, its worh the extra 40EUR to spring for the x86 models because i dont have to reprogram all my applications
[04:06:39] <minibnz> the instruction que on a pc has to work out what is intended.. ifyou have 100 choices you gotta ask 100 questions before you know what command it is.. now if you reduce the instruction count you ask less questions which makes things go faster
[04:06:43] <AmsterdamJoe> minibnz: actually, a reduced set of insturctions makes a defining a given function more verbose
[04:07:43] <AmsterdamJoe> again, for me, as an individual its not worth converting my softwares to run on RISC
[04:08:26] <minibnz> just about every phoen uses a risc cpu if thats not a big enough reason then welll...
[04:08:45] <AmsterdamJoe> i guess it would be efficent enough if some percent of all computer users decided to migrate to RISC -- but i dont like these kind of plans where everyone has to go along for it to be profitable
[04:09:11] <AmsterdamJoe> now you mentioned it, i guess everyone does (have a RISC in their phone)
[04:09:42] <AmsterdamJoe> still, that does not mean it makes sense
[04:10:17] <minibnz> just release it as source code then anyone can make it work for thier system with out you having to worry about it
[04:10:27] <AmsterdamJoe> lol wut?
[04:10:50] <AmsterdamJoe> im not worried about it
[04:11:09] <AmsterdamJoe> i think i mentiond my concern is presently with making some CNC cloggs
[04:11:46] <minibnz> and what have you done towards that goal? have you got your desgin sorted or any cad files yet?
[04:12:13] <minibnz> have you decided how you are going to get that info into linuxcnc?
[04:12:22] <AmsterdamJoe> i inspected the milling machine, installed linux with realtiem kernel and yea i have a 3d model for the shoes
[04:13:02] <AmsterdamJoe> no, i dont know about linuxCNC formats etc
[04:13:06] <AmsterdamJoe> ...yet
[04:14:34] <minibnz> ok so you have made progress... sweet what format are the cad files? and is the mill all configured?
[04:14:55] <AmsterdamJoe> its configured to work with windows
[04:15:16] <minibnz> no no no not that.. are the axis all configured
[04:15:24] <AmsterdamJoe> it has a pair of USB cables going to the computer
[04:15:32] <AmsterdamJoe> i dono
[04:15:43] <AmsterdamJoe> "ShopBot"
[04:16:01] <minibnz> ok that would be the first thing to do.. configure linuxcnc so that when you tell the axis to move 10mm it goes 10mm
[04:16:19] <AmsterdamJoe> http://fablab.waag.org/machine/big-milling-machine
[04:16:28] <minibnz> if you dont have access at the moment i would start working on the cad files.
[04:16:57] <AmsterdamJoe> how would you work them?
[04:17:00] <minibnz> yeah not too sure how you are going to do the toe holes of the clog with that machine.
[04:17:25] <AmsterdamJoe> dont worry about that minibnz there are clogg making experts here
[04:17:34] <minibnz> you can do the heal area but i dont think its going to be able to hollow out the toes on it.
[04:18:18] <AmsterdamJoe> im not worried about doing that particular area with the machine
[04:18:32] <boboss> hello, do linuxcnc works with a usb board (like ramps1.4)?
[04:18:38] <minibnz> and how i would get the cad files into linuxcnc all depends on what format it is..
[04:19:10] <AmsterdamJoe> hi boboss
[04:19:11] <minibnz> boboss no.. they run marlin firmware which is a incomplete gcode stack and wont work well on a mill..
[04:19:36] <minibnz> there are also other firmwares for them but from what i have seen they all lack milling gcodes.
[04:19:54] <minibnz> no spindle control no arc paths and a few other things
[04:20:19] <minibnz> you might have some luck with GRBL firmware but i have not looked at this.
[04:20:23] <boboss> smoothieboard ?
[04:20:53] <minibnz> as far as i am aware they all run a short gcode stack, you need to look at the wiki page and see what is supported.
[04:21:21] <minibnz> you will have better luck on a smoothie as it has more processing power.. you can add the missing commands if you really want to..
[04:21:33] <boboss> ok
[04:21:55] <boboss> and can it work with a raspberrypi ?
[04:23:04] <minibnz> yeah i have seen hackaday things running linuxcnc on a raspberry pi (1 and 2) but you wont break any speed records from what i have been told. its gpio port appears to be a bottle neck
[04:24:02] <boboss> I read that too ....
[04:24:25] <boboss> Thank you for the information
[04:25:16] <minibnz> from what i have been told a beaglebone black might be worth looking into..
[04:26:09] <minibnz> they are pretty good without active cooling you can over clock them to ~1.3ghz more if you add a fan to move the heat..
[04:28:24] <Sync> minibnz: just don't cut any arcs? you can just do a lot of straight lines ;)
[04:28:49] <minibnz> yeah this is how they get away with it for 3d printing..
[04:30:03] <minibnz> i am mainly worried about it cuz the DXF2gcode python program i use, spits out arcs.. i tried moving gcode to my printer and it was missing lots of bits..
[04:31:21] <minibnz> adding spindle control is pretty easy my github account has a repo of marlin+ spindle control so i can test out my laser..
[04:34:34] <XXCoder> Jymmm: I'm alive. I think.
[04:37:07] <minibnz> so in general if you want more accuracy you cut slower or still keep to the SFM rules? i am trying out cutting a gear going a lot slower than before.. after this i will try cutting faster and see how different the two parts are.
[04:37:31] <XXCoder> sometimes it seems to me to be black art lol
[04:37:49] <XXCoder> just play with numbers a little and learn thats best I can say reallty
[04:38:06] <XXCoder> you have easier time of it as youy can hear "good cutting sound"
[04:38:09] <minibnz> yeah was trying to work out if there is some cosmic rule or if it is the way i am standing on one foot and squinting my left eye..
[04:38:46] <SpeedEvil> There are rules for all circumstances.
[04:38:53] <SpeedEvil> the fun is working out which rule applies
[04:39:03] <minibnz> yeah thats what i have been going by. looking at the swarfe and listening to the cuts. with plastics its hard to hear a bad cut on my machine
[04:39:04] <SpeedEvil> you get better accuracy with decreasing cutting forces.
[04:39:11] <SpeedEvil> Unless you don't.
[04:39:28] <minibnz> ahh ok i see so its not speed directly but a combination..
[04:39:29] <XXCoder> minibnz: theres "burnt look" of bad cuts, besides usual bad cut stuff
[04:39:33] <SpeedEvil> (because for example the tool is skating across the surface of the work and not cutting to a nice defined depth
[04:39:39] <XXCoder> burnt is too slow
[04:39:53] <XXCoder> *for plastics
[04:39:53] <SpeedEvil> In general - the condition of the chips or removed material will tell you stuff.
[04:40:16] <SpeedEvil> But what it tells you varies with material
[04:40:28] <minibnz> well i am getting nice fluffy shavings at the moment so i say this combination isnt bad yet.. its probably not the best but meh :)
[04:42:44] <minibnz> will have to see what the cut edges are like. i am basically trenching with my cutter. so i dont expect it to be super accurate as the forces change directions depending on what side/face of the gear tooth its cutting..
[04:45:15] <minibnz> i could probably do this in 2 passes if i wanted to chase speed. 1 pass at 1mm then a big 5mm pass to finish and see what that gets me :)
[04:45:52] <minibnz> just dont know exatcly how hard i can push a 2mm cutter with out pissing off the neighbours by spinning it up too hard.
[04:53:23] <XXCoder> wb jdh
[04:53:25] <XXCoder> er Jymmm
[04:55:28] <minibnz> hmm interesting.. this gear i just cut is an internal tooth gear with rounded lobes. the part i want to keep looks nice and clean but the center bit that dropped out has 4 ridges in it one from each 1.5mm cut on all the circumference.. can anyone explain whats going on?
[04:56:06] <minibnz> is this just due to the backlash when it changes from conventional to climb milling?
[04:56:08] <XXCoder> that is why you need finish pass
[04:56:27] <XXCoder> your tool is very slightly bent as its cutting
[04:56:37] <XXCoder> so if you do more than one depth it shows up
[04:57:20] <minibnz> ahh ok so more spindle speed was needed to reduce the cutting force or less depth or less travel speed or a combination of these?
[04:57:21] <archivist> nothing is completely rigid and error free
[04:57:36] <XXCoder> none, just add finish pass
[04:57:51] <XXCoder> it cuts all down at once and it should remove that very slight ridges
[04:57:53] <archivist> design your cutting path to minimise error
[04:58:16] <minibnz> well this part i can add but the next parts i want to cut has external teeth and the part will drop out before it can be cleaned up..
[04:58:52] <archivist> cut gears with a form tool
[04:59:07] <minibnz> i will need to find better way to hold the sheet
[04:59:18] <XXCoder> that or a clamp change step
[04:59:38] <XXCoder> add clamps to places already cut and remove clamps that is covering uncut parts
[04:59:45] <XXCoder> though this isnt best way
[05:00:16] <XXCoder> other method is inside/outside cuts switch (first inside hole(s) then add clamps to that, then remove external clamps
[05:00:23] <archivist> I cut out a disk, mount on rotary and use a form tool so the cutter only cuts conventional and backlash is removed in the gcode
[05:00:23] <minibnz> yeah and cutting rounded lobes on the 4th axis is going to require some special gcoding :)
[05:00:32] <XXCoder> though you have to do that right or stock will lift on cut
[05:03:29] <minibnz> the size of these gears are going to require a peice of round stock that is long enough so i can hold it in my 4th axis. cuz they are too small to get any sort of screws or bolts to hold it to a plate.. maybe i could make a mandrel to hold them in the chuck of the 4th axis
[05:04:32] <archivist> does your 4th axis have the resolution needed?
[05:07:10] <minibnz> it is currently setup with about 26steps per degree.. it should do it
[05:07:45] <minibnz> i can turn up the microsteps if i need more steps at the cost of holding force
[05:08:32] <archivist> I was just checking it was not one of those direct stepper things with no reduction
[05:09:04] <minibnz> but its pretty strong.. i cut a augar out of aluminium for a filament extruder it came out really nice, no noticable steps in the screw.. it worked well except that the alu stains the plastic as it goes thru..
[05:09:10] <archivist> better ones have a worm drive
[05:10:04] <minibnz> was going to go a worm drive but my mate looked at it and said that about 4:1 belt drive will be good. i think its something like 44:18 teeth..
[05:12:31] <archivist> I have 2mm arbour for small work http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_09_30_Ford_speedo_gears/IMG_1839.JPG
[05:13:42] <archivist> part of the main use of arbours is transfer between lathe and mill or hobbing machine and back
[05:13:47] <minibnz> nice i havent gotten around to making all the little tools and hodlers i need.. while my gears are not that small but still too small to hold
[05:14:03] <minibnz> ahhh makes setup easy
[05:15:02] <archivist> or you make a stick of gears http://www.collection.archivist.info/archive/DJCPD/PD/2002/2002_09_18_Wheelcutting/P9190303.JPG
[05:15:26] <archivist> http://www.collection.archivist.info/archive/DJCPD/PD/2002/2002_09_18_Wheelcutting/P9190302.JPG
[05:16:07] <archivist> the spigot fits the collet on either machine, then part off
[05:16:36] <minibnz> that was what i was going to do.. make a cutter up that will form the teeth in once go.. i made a small cutter a while back to cut the teeth on the drive bolt on my 3d printer. it worked well on brass and steel if you go gently.
[05:17:23] <minibnz> i have some bits of tool steel to make cutters out of..
[05:17:51] <archivist> or on the end of a stick http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_03_31_contrate_gear_prototype/IMG_1205.JPG
[05:19:08] <minibnz> that be some tiny ass gears getting cut there :)
[05:20:01] <archivist> that was the cutting of top left http://gears.archivist.info/gears/IMG_1214_hires.JPG
[05:20:40] <minibnz> nice
[05:21:43] <archivist> that was plain bar into a collet on the rotary
[05:22:44] <minibnz> my rotatry cant take a collet..
[05:22:53] <minibnz> its too small..
[05:23:30] <minibnz> its only like 50mm diameter chuck and can only hold 20mm shafts but its big enough for what i want to do..
[05:23:31] <archivist> its erm...essential :)
[05:24:03] <archivist> chucks are often far too inaccurate
[05:26:30] <minibnz> yeah but that would require building a new one..
[05:27:19] <minibnz> and find collets to be so restricting in what you can hold.
[05:28:00] <archivist> I use morse taper collets in a cheap ish vertex rotary
[05:30:48] <minibnz> cant use a MT in a verticle fashion cuz you cant get to the bolt at the back..
[05:31:42] <archivist> sure you can with a spacer or angle bracket
[05:32:12] <minibnz> yeah and that just eats even more into my prescious head room
[05:32:53] <minibnz> on a real mill sure space it out all you want.. on a mini mill you do all you can to avoid spacing things out
[05:33:38] <archivist> I had to jack up the column, I know about space :)
[05:34:04] <archivist> early arrangement http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_02_03_cnc/P2030017.JPG
[05:34:35] <archivist> middle http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_02_18_cnc/P2180014.JPG
[05:35:46] <archivist> 5 axis really cramped http://www.collection.archivist.info/archive/DJCPD/PD/2009/2009_05_27_cnc_making_pin_wheel/IMG_0252.JPG
[05:36:17] <archivist> jacked http://www.collection.archivist.info/archive/DJCPD/PD/2009/2009_07_10_cnc_with_LCD_P4/IMG_0268.JPG
[05:36:48] <archivist> and added stiffening to the crappy column
[05:38:23] <minibnz> is that a stepper on the top?
[05:38:29] <minibnz> is that for threading?
[05:38:35] <archivist> yes, Z
[05:38:51] <minibnz> ahh ok
[05:42:32] <minibnz> i thoguht about adding a threading stepper but dont really think i need it..
[05:43:15] <archivist> use gcode, stop thinking outside linuxcnc
[05:43:48] <archivist> eg http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_07_24_p1010025_cnc_thread_milling_worm_and_wheel/P1010026.JPG
[05:44:01] <minibnz> yeah its pretty each but needs cutters :)
[05:44:32] <minibnz> easy.. but so many cutters needed
[05:44:42] <archivist> that is a plain v cutter
[05:44:48] <archivist> as is http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_10_07_Merlin_worm/p1010054.jpg
[05:45:23] <minibnz> and i was talking more on internal threads.
[05:45:25] <archivist> second produced http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_10_07_Gear_cutting_examples/p1010059.jpg
[05:45:58] <minibnz> noce
[05:45:59] <minibnz> nice
[06:23:34] <minibnz> i ordered a larger diamond wheel now i just need to make an arbor next time im near a good lathe.. then i can grind my tools in the spindle and 4th axis. going to make a mount for the bed and the head to hold the wheel at angles to form the cutters i need a sharpening stone to finsh them off
[06:25:12] <minibnz> i have a set of smaller discs that i use to make the cutting edges and reliefs but needed one to remove bulk material in a controled fashon
[06:45:50] <Jymmm> 'nick jymmm
[06:45:55] <Jymmm> \nick jymmm
[06:45:59] <Jymmm> bah lol
[06:46:13] <Jymmm> XXCoder: ty
[06:46:24] <XXCoder> fails heh
[06:46:48] <Jymmm> It's 4am and only had one sip of coffee, it's justified =)
[06:47:15] <XXCoder> :)
[06:49:04] <Jymmm> I think I better wait a while before mucking with ssh keys; that's all I need is typoing ssh keys
[06:49:26] <XXCoder> its amazing how much damage one space added can do
[06:49:36] <Jymmm> hahaha, no doubt
[06:52:21] <XXCoder> it almost happened to me
[06:52:34] <XXCoder> I almost hit return when I saw space between . and /
[06:53:13] <Tom_itx> Jymmm go for it... it'll keep ya guessin the rest of the day
[06:53:30] <Jymmm> just as long as rm -rf wasn't prefixed =)
[06:53:36] <XXCoder> it was
[06:53:48] <XXCoder> rm -rf . /
[06:54:29] <Jymmm> Tom_itx: lol, well thats the nice thing about ssh keys, there's no typoing the pw =)
[07:22:14] <malcom2073> XXCoder: iirc, rm won't let you do that anymore :P
[07:25:00] <beikeland> rm -rf . / is something you only do three or four times ;)
[07:25:51] <archivist> I had to do a 150 mile round trip to fix a computer where an idiot did that in his DOS root :)
[07:26:59] <Jymmm> beikeland: if > 1 == idiot;
[07:27:25] <beikeland> hehe, not afraid to admit it. I'm at 2.
[07:27:45] <Jymmm> beikeland: how the phuk did you manage that?
[07:28:05] <malcom2073> Why do you use rm -rf ./ isn't cd .. rm -rf foldername the same?
[07:28:22] <malcom2073> I try to avoid using the character / in rm in any way :P
[07:29:37] <beikeland> first time i think i wanted to do rm -rf folder & because it would take a while. but i interchange US and NO keyboard layouts, and that changes / to &
[07:30:01] <Jymmm> beikeland: Ah, ok.
[07:30:13] <beikeland> not sure the 2nd time
[07:31:57] <beikeland> .. it I was right about that it would take a while though >D
[07:32:28] <Jymmm> beikeland: and you did it to root both times?
[07:34:09] <beikeland> Jymmm: sadly. 2nd time was just a virtual test system so less of an issue though
[07:34:25] <Jymmm> beikeland: lol, fair enough =)
[07:34:59] <Jymmm> beikeland: May I introduce you to http://www.nongnu.org/rdiff-backup/
[07:35:24] <Jymmm> It's like rsync + diff
[07:37:14] <beikeland> Jymmm: lol, vmware esxi and snapshots now. but maybe i should do that for my linuxcnc configs
[07:38:57] <Jymmm> beikeland: Yeah, I love rsync
[07:41:51] <lair82> Good morning Guys,
[07:43:40] <lair82> I was wondering if it is ok to clean the terminal strips on this machine I am working on with soap and water. I am still installing the machine and am weeks away from even hooking the power up to the machine, and there a few terminal boxes on the mill that the terminal strips are dusted with dirt and oil.
[07:44:17] <Jymmm> lair82: do you have any contact cleaner?
[07:44:29] <archivist> whatever is safe for the plastics
[07:45:12] <lair82> I just emptied my last can :( and am no where's near fininshed. I could use another 3-4 cans.
[07:45:54] <Jymmm> lair82: is it like old grease/oil/coolant?
[07:46:28] <lair82> I just figured instead of blowing another 60-70 bucks in contact cleaner, just use the general cleaning solution we use around here to clean them instead.
[07:47:03] <lair82> Jymmm, yes grease grime dirt dust oil type crap all over the terminal strips
[07:47:41] <Jymmm> *I* don't like using soap/water on electrical as it could leave a film and then water has a tendancy to go into places you don't want it to. I use denatured alcohol and old toothbrushes
[07:48:25] <Jymmm> a gallon is $16 and last forever, also great evaporate really quickly
[07:48:53] <lair82> the main term strip on the head, near the spindle doesn't have gasketed covers on the terminal boxes, and there is about 50-60 control terminations and the main spindle power terminations are in the one I am cleaning right now.
[07:49:09] <archivist> I often also use "white spirit" (paint brush cleaner)
[07:49:48] <lair82> I have a few quarts of denatured alcohol around, I will go grab one and a brush.
[07:49:59] <archivist> lasts a bit longer in the ultrasonic
[07:50:15] <Jymmm> lair82: go easy on the brush, has a tendancy to splash in eyes
[07:51:16] <Jymmm> lair82: and has an invisible white flame if ignighted as it's 190 proof =)
[07:51:24] <jdh> hard to beat soap and water for cleaning. doesn't sound ideal for electronics though
[07:52:35] <Jymmm> That reminds me, I need to find some MEK
[07:52:53] <lair82> I just remember at the other place I worked at, we had High frequency Induction welders, ( 300 KW output) and yearly we would completely dismantle them, and clean everything with dawn dish soap and water,
[07:53:36] <lair82> You could eat off the the components ;) hahahaha
[07:53:42] <Jymmm> the magnetics? or PCBs?
[07:53:50] <lair82> Everything
[07:54:03] <lair82> Top to bottom inside and out
[07:54:18] <Roguish> lair82: find some carbon tetra chloride. it's the best degreaser / terminal cleaner
[07:54:33] <Jymmm> Well, I know some ppl toss their keyboard into the dishwasher a couple of times a year. I never would personally.
[07:55:12] * Jymmm looks over at the two cans of 1,1,1
[07:55:15] <malcom2073> I just replace my keyboard once a year heh
[07:55:52] <lair82> The cabinets were roughly 96" square by 120" tall, full of components, choke tubes, disc capacitors, tank capacitors, oscillator tubes, phenolic boards, all kinds of very expensive stuff
[07:56:07] <archivist> we used to use water for printer electronics to clean the ink off, making sure they were dry was a pain
[07:56:47] <Jymmm> Oh thats the other thing, if you do use water, rinse with denatured alcohol helps to remove water
[07:57:06] <lair82> I will just go with the denatured,
[07:57:15] <lair82> I always forget about that stuff
[07:57:32] <Jymmm> lair82: also great for cooking =)
[07:57:46] <archivist> for clock mechanism we use a water based clean and a spirit base rinse/dewater
[07:59:02] <Jymmm> lair82: Great lil alcohol stove http://www.dx.com/p/locs-portable-camping-alcohol-stove-spirit-burner-black-golden-256330
[07:59:06] <lair82> Thanks Guys
[08:00:23] <CaptHindsight> Jymmm: I cook with ethanol. Less chance of going blind. :p
[08:00:46] <Jymmm> CaptHindsight: I'll take a pint or gallon
[08:01:27] <Jymmm> the hazmat fees for shipping are fucking nuts
[08:02:38] <CaptHindsight> nah $35
[08:02:41] <Jymmm> CaptHindsight: Can only get the weak everclear in Calif
[08:03:05] <CaptHindsight> 190 proof = 95%
[08:03:27] <CaptHindsight> have to get yourself a molecular sieve
[08:03:28] <Jymmm> CaptHindsight: 190 proof everclear is NOT available in calif
[08:03:54] <jdh> nor MEK?
[08:03:58] <CaptHindsight> really? Whats the backstory on that?
[08:04:30] <Jymmm> jdh: Not sure if it's county/region ban or state wide on MEK
[08:04:39] <malcom2073> Probably some politicians kid drank themselves to death
[08:04:41] <CaptHindsight> oh that right you're in CA, yeah we have to watch the VOC's we ship there for consumer use
[08:04:44] <Jymmm> CaptHindsight: No clue, only 151 proof is available in Calif
[08:05:22] <CaptHindsight> California VOC regulations, it's a state thing
[08:05:57] <Jymmm> CaptHindsight: So yes, I'd love to have/use (food grade) ethanol, just cna't get the stuff affordably
[08:06:15] <Jymmm> due to hazmat/shipping fees or bulk qty requirements
[08:06:50] <CaptHindsight> you can walk into a Home Dept here and purchase MEK, Xylene, Lacquer thinner etc
[08:06:50] <Jymmm> a gallon would last me forever
[08:08:31] <Jymmm> not sure if xylene is still available or not, I dont use it all that often. but napatha is, and there was a recalled MEK substiture that has never been replaced. I need to make a run to the border!
[08:09:10] <Jymmm> state border that is... illegal smuggling of chemicals into the state!
[08:09:29] <CaptHindsight> can you buy >90% IPA at a pharmacy?
[08:10:17] <Jymmm> not sure, never looked
[08:10:26] <CaptHindsight> IPA = isopropanol
[08:10:28] <Jymmm> but IPA has that additive in it
[08:10:54] <gonzo_> naptha is sold over here as camping stove fuel, or some panel wipe is naptha
[08:11:12] <Jymmm> gonzo_: Yep =)
[08:11:41] <Jymmm> I use vodka as a pathetic substitute for food grade enthanol
[08:15:17] <CaptHindsight> and you're allowed 0.00 per year for personal distillation
[08:16:49] <CaptHindsight> and yet perfumes and colognes are exempt
[08:17:52] <gonzo_> you need to import a scent called 'Pure'
[08:18:09] <gonzo_> the perfume for men (who clean PCBs)
[08:18:51] <_methods> sex panther pcb
[08:19:07] <CaptHindsight> smells of rosin
[08:19:36] <_methods> you can get 90%+ at pharmacy
[08:19:44] <_methods> just make sure you check the labels
[08:19:51] <_methods> IPA
[08:21:39] <CaptHindsight> my parts from China small like they were soaked in numerous solvents yet it's difficult to purchase even IPA there
[08:22:13] <CaptHindsight> no solvent paints at Home Depot
[08:23:46] <CaptHindsight> and liquids have to be sent from the distributor direct to the end user, then you're stuck with it wherever you are, you can't reship it
[08:26:06] <PetefromTn_> SUCH BS!
[08:26:18] <CaptHindsight> this help ensure that only those licensed can store it improperly and destroy and entire shipping depot and town
[08:26:30] <CaptHindsight> and/an
[08:26:36] <gregcnc> see they do understand how things are done there and don't want to put the public at any more risk than needed
[08:27:07] <PetefromTn_> Oh and GOOOOD MORNING LINUXCNC!!!!!!
[08:28:05] <_methods> damn PetefromTn_ in here early
[08:28:32] <PetefromTn_> well yeah I am not working outside my own shop right now
[08:29:14] <PetefromTn_> finishing up the last few items to be CNC machined before I turn to the house upgrades I need to do over here.
[08:32:20] <_methods> i feel sorry for the UK
[08:32:31] <_methods> poor bastards
[08:32:33] <PetefromTn_> Dear lord if I have to see just ONE MORE unwanted Kardashian article or photo crammed on my PC screen I may do something I will have to be forgiven for :D
[08:32:47] <PetefromTn_> well yeah...what is it this time?
[08:33:28] <_methods> we managed to destroy that car show they all watch
[08:33:38] <PetefromTn_> We?
[08:33:40] <_methods> hot gear or whatever
[08:33:41] <_methods> yeah
[08:33:46] <_methods> 'murrica
[08:33:48] <PetefromTn_> we didn't do anything
[08:33:56] <Jymmm> PetefromTn_: Well, get just this beforehand... http://www.amazon.com/dp/B005MR3IVO
[08:33:59] <_methods> we managed to get that joey guy unleashed on them
[08:34:09] <_methods> the friends dude
[08:34:19] <PetefromTn_> its not our fault whatshisface punched whoshisface?
[08:34:26] <_methods> hahahah
[08:34:41] <_methods> i'm just glad we got rid of joey
[08:34:53] <PetefromTn_> Jymmm dafuq?
[08:34:56] <_methods> or whatever his real name is
[08:35:11] <PetefromTn_> are you talking about US top gear?
[08:35:18] <_methods> yeah top gear
[08:35:23] <malcom2073> "As UPS discretely unloaded my 55 gallon drum, the driver accidentally spilled it into my driveway. Any amount of cars can now fit into the garage."
[08:35:27] <malcom2073> That's awesome
[08:35:28] <PetefromTn_> no US top gear...
[08:35:29] <_methods> hahahah
[08:35:44] <_methods> oh it's only US top gear
[08:35:54] <_methods> so we didn't manage to ditch that douche bag on the UK?
[08:36:12] <_methods> is it kosher
[08:36:13] <_methods> lol
[08:36:17] <_methods> no it's used for porking
[08:36:43] <PetefromTn_> Those comments are hilarious
[08:36:49] <_methods> freakin awesome
[08:37:01] <_methods> those are as good as the sugar free gummy bears
[08:37:10] <PetefromTn_> too many people have way too much bloody free time LOL
[08:38:25] <gregcnc> https://www.nemopowertools.com/en/products/ waterproof electric hand tools?
[08:41:19] <PetefromTn_> yeah man I need me some 900 dollar cordless drills hehehe

[09:38:52] <_methods> i love bidspotter
[09:42:14] <SpeedEvil> For when you need a CNC table you can put your house on.
[09:45:55] <CaptHindsight> setup 100's of parts, come back at the end of the day
[09:52:29] <gregcnc> https://www.instagram.com/explore/tags/billetspin/ are tops a thing?
[09:54:31] <PetefromTn_> hell yeah they are
[09:55:01] <gregcnc> what does stuff like that sell for?
[09:59:14] <SpeedEvil> The thing I linked has 300K as a minimum bid
[09:59:16] <SpeedEvil> $500K
[09:59:28] <_methods> custom tops lol
[10:00:50] <_methods> hahah the comments are hilarious
[10:00:58] <_methods> thereal_catboyWhat's cool about a top?
[10:01:45] <_methods> i guess if you don't have any work you gotta find something to do lol
[10:02:49] <_methods> i think i'd make custom valve stem caps before i made custom tops though
[10:03:04] <_methods> at least you know you'll sell 4 of those at a time hahahahah
[10:15:56] <tiwake> PetefromTn_: http://tiwake.com/DSCN0082.JPG
[10:19:07] <tiwake> CaptHindsight: your company sells dyes?
[10:19:36] <PetefromTn_> tiwake what are you showin' me man?
[10:19:52] <tiwake> PetefromTn_: the parts I've been anodizing :3
[10:20:13] <PetefromTn_> taste the rainbow ;)
[10:20:39] <tiwake> I also did some slow-dip of purple and blue for a faded effect
[10:20:59] <_methods> anodize came out good
[10:21:01] <tiwake> one end is lighter than the other, looks cool
[10:21:39] <tiwake> but my red dye is... donno... weird
[10:21:41] <PetefromTn_> what was your time in the bath?
[10:21:52] <CaptHindsight> tiwake: we make solvent dyes for anodize, so they can be used for layering with water based dyes and won't wash out with water
[10:22:10] <tiwake> anodizing time I put it in for ~2 hours, give or take 10min or so
[10:22:38] <CaptHindsight> also for inkjet, screen printing, airbrush etc for anodize
[10:23:11] <PetefromTn_> did you have to wipe them with oil or were they that sheen beforehand?
[10:23:35] <tiwake> CaptHindsight: well, my red dye is weird... its like it rubs off, none of the other casswell dyes I have do that... but it seems to "hold" the color alright, just cant touch the part
[10:24:38] <tiwake> PetefromTn_: I did not do any other surface stuff than anodize, dye, and seal
[10:25:43] <tiwake> sometime soon I'm going to be buying bucks, one bucket for each color of dye
[10:26:54] <tiwake> but I'm not really sure what to do about red other than try a different dye
[10:27:33] <CaptHindsight> the red rubs off after sealing?
[10:27:46] <tiwake> no, before sealing
[10:27:51] <tiwake> after sealing it seems fine
[10:28:05] <tiwake> like
[10:28:28] <tiwake> I drop the parts in the red dye for, donno, 15min or whatever
[10:29:13] <tiwake> I pick them out (with gloves of course) and where my fingers touch instead of red its pink
[10:29:25] <CaptHindsight> I don't mess with water based dyes for anodize much since they are all mostly the same dyes and there are several vendors
[10:30:18] <tiwake> but if I leave my wire inside of the part and dunk it in the red dye that way, and pull it out from the wire, never touching the part
[10:30:21] <tiwake> its fine
[10:31:03] <tiwake> it could be they sent me some not very good red dye... donno
[10:31:20] <CaptHindsight> you shouldn't be touching any dyes areas before sealing
[10:31:31] <CaptHindsight> dyes/dyed
[10:32:53] <tiwake> whats wrong with that?
[10:39:11] <tiwake> also some white dye would be nice XD
[10:40:30] <anomynous> tralala
[10:45:14] <tiwake> what is the process called when you take stainless steel and erode away all the iron on the surface so it is more resistant to oxidizing?
[10:45:27] <SpeedEvil> passivating
[10:45:39] <tiwake> (thanks, couldent remember)
[10:46:25] <tiwake> would a passivated 316 stainless steel plate be good for the ground plate for an anodizing bath?
[10:46:26] <anomynous> hmm
[10:46:30] <anomynous> doesnt that happen naturally
[10:46:33] <anomynous> passivation
[10:47:50] <tiwake> right now I'm using an aluminum plate and pulling it out every night... I'm lazy and don't want to pull out the plate and clean it every time I do some parts
[10:56:49] <tiwake> CaptHindsight: can I try out a red and white dye? how would I buy some (sample) from you?
[11:02:08] <Erant> tiwake: How would graphite be?
[11:02:40] <Erant> Brittle, obviously, but resistant to pretty much any erosion.
[11:02:45] <tiwake> Erant: graphite for... the ground plate?
[11:02:52] <Erant> Yah
[11:03:17] <tiwake> Erant: interesting... can you get sheets of it? probably only comes in rods.. hmm
[11:03:30] <tiwake> or rectangle
[11:03:41] <tiwake> a sheet would break in half if you breath on it wrong
[11:03:47] <Erant> http://www.ebay.com/itm/5pcs-99-99-Pure-Graphite-Electrode-Rectangle-Plate-Sheet-50-40-3mm-/271646734150?hash=item3f3f683746:g:4Q8AAOxy7nNTRbqj
[11:04:13] <Erant> Now, that's a china special, so take 99% with a grain of salt.
[11:04:23] <Erant> But it seems like a cheap enough thing.
[11:05:09] <tiwake> 50mm is only just shy of 2"
[11:05:30] <tiwake> those things are tiny
[11:05:33] <Erant> How big do you need it?
[11:05:59] <tiwake> uh
[11:06:29] <tiwake> I think something like 10"x16"
[11:07:37] <Erant> Little bit more expensive, but 4 of these would work: http://www.ebay.com/itm/1-4x4x12-Graphite-plates/301865378585
[11:07:55] <_methods> tiwake: i don't think you're supposed to use stainless for ground plate
[11:08:04] <Erant> Apprently they use graphite blocks for EDM as well.
[11:08:28] <tiwake> _methods: not supposed to because the iron gets in the bath and screws with the anodizing process
[11:08:44] <tiwake> _methods: but if its passivated?
[11:08:46] <_methods> i think because it can offload hex chrome
[11:08:48] <gregcnc> aluminum or lead are typical choices
[11:08:54] <_methods> but i'm not sure 100%
[11:09:07] <tiwake> hmm
[11:09:20] <Erant> gregcnc: Anything particularly wrong with graphite?
[11:09:23] <Erant> It's what I'd use.
[11:09:28] <Erant> Inert as f'.
[11:10:49] <_methods> tiwake: http://www.finishing.com/73/69.shtml
[11:11:16] <_methods> they seem to be recommending 6063 t6 as cathode
[11:12:03] <rene-dev> ssi do you require DIN rail clips for your rectifier board? I just got some lasercut
[11:12:45] <tiwake> _methods: I'm just a bit concerned because I want to leave the plate in the bath for extended time without being used
[11:13:05] <_methods> well stainless would definitely last longer
[11:13:21] <gregcnc> hmm. graphite is also used in some cases
[11:13:30] <Erant> Yeah, I'm seeing that.
[11:13:40] <Erant> Apparently the voltage drop across aluminum is the least though
[11:13:44] <Erant> So it's the most efficient.
[11:13:53] <Erant> For graphite and lead, you're generating more hydrogen.
[11:14:10] <Erant> "The voltage drop on the cathodes is principally attributed to the cathodic reaction resistivity. In the case of anodizing aluminum in sulfuric acid solution, for example, major cathodic reaction is hydrogen evolution. As indicated in many references, the hydrogen evolution resistivity on lead, stainless steels, or graphite is much larger than that on aluminum. As a result, the voltage drop on aluminum cathodes is the least among the cathodes mentioned above
[11:14:25] <Loetmichel> *meh* just ran the gauntlet of Officials for registering a new used car to my name and get license plates... got the car home... 1994 BMW 316i... in daylight it has even more rust than i saw yesterday night when i bought it... and i managed to break the back of the driver seat... so i had to put 2 of the summer tires behind the seat to prop it up... but its dry inside, the engine souds well
[11:14:25] <Loetmichel> and it still has 4 months to the next MOT... time enough to get my Opel Omega repaired ;)
[11:14:52] <tiwake> hmm
[11:15:12] <tiwake> I've heard of titanium being used too
[11:15:20] <Erant> $$$
[11:15:39] <Erant> Loetmichel: Whatcha doing with it? Fix it up?
[11:16:00] <SpeedEvil> new IC spindle motor?
[11:16:10] <Loetmichel> ... and i have to say: a manual shifter isnt that "easy" when you have driven only automatics for the last 10 years... took me a moment to not choke it at the traffic lights ;)
[11:16:47] <witnit> I installed a copy of windows 10, first time doing a fresh windows build since win98SE. I have never been more displeased by software. :( quickbooks needs to hurry and put out a linux compatible version
[11:16:49] <Loetmichel> Erant: bought a car to drive to work for the time my Opel needs to be in the Garage
[11:17:11] <gregcnc> what we call in the US a "beater"
[11:17:14] <tiwake> witnit: they might never do that
[11:18:10] <tiwake> anyway, gotta go to work... bbl
[11:18:42] <Erant> Gotta make sure to wear a wifebeater while driving your beater.
[11:18:43] <Loetmichel> gregcnc: hmm?
[11:18:58] <gregcnc> junk cars just to get you were you need to be
[11:19:16] <gregcnc> 'Cathodes' that, "Stainless steel cathodes are used for chromic acid anodizing and for some integral color anodizing processes and graphite is used in mainly continuous anodizing processes...."
[11:20:21] <SpeedEvil> Now I want to see a hod full of cats
[11:22:49] <gregcnc> blah i should make something or work on the lathe build
[11:52:59] <Roguish> hey you machinists, do you use a z-axis tool setter?
[11:53:32] <Roguish> one of the blocks or something that lights up or beeps when it's touched on the top?
[11:54:02] <archivist> I dont because I want the tool centre line
[11:54:41] <Roguish> this would only be for the tool length offset
[11:54:49] <Roguish> i think.

[11:55:41] <_methods> piece of paper
[11:55:43] <maxcnc> hi out of germany
[11:55:45] <gregcnc> isn't there a drivers seat on it?
[11:55:55] <Jymmm> https://cdn.globalauctionplatform.com/3e30874b-89f0-4b6a-8fb5-a58e00e30d84/52cfdc24-22e2-445f-a2ac-82e337604d45/original.jpg
[11:56:45] <maxcnc> Frank__5: and is it running
[11:57:30] <gregcnc> the pendant cable looks long enough
[11:58:25] <Jymmm> gregcnc: Think so huh? https://cdn.globalauctionplatform.com/3e30874b-89f0-4b6a-8fb5-a58e00e30d84/ac9aba0d-e34c-4e4e-836e-42c1b9befd1f/original.jpg
[11:58:27] <maxcnc> RagingComputer: this makes life lot easyer with auto zero
[11:59:32] <maxcnc> Roguish: ? up to you
[11:59:46] <Jymmm> gregcnc: long eough to reach the other side maybe =)
[12:00:19] <Roguish> maxcnc. just getting used to a Haas VF4, and using G43 and tool offsets.
[12:00:23] <gregcnc> that's all you need, right?
[12:00:50] <gregcnc> you won't be touching off from the far end of the table without binoculars
[12:01:13] <Jymmm> gregcnc: If it's jogging at 130 IPS, you would have to be running to catch it =)
[12:02:11] <maxcnc> Roguish: the Devels now included also the Variables of the mashine coordinate system so on Zeroing its now easy to do on the calculations
[12:14:18] <SpeedEvil> Jymmm: Maybe it has a nice seat fitted?
[12:17:10] <Jymmm> SpeedEvil: or at east come with one of these https://www.youtube.com/watch?v=7t8WUHDxRy0
[12:17:35] <Jymmm> least*
[12:19:30] <Jymmm> Not a bad idea less the wood part... cordless drill trolling motor https://www.youtube.com/watch?v=rZJTGqmtzBs
[12:22:34] <Jymmm> PetefromTn_: Here ya go... kayak motor https://www.youtube.com/watch?v=Ycf5faQnS3A
[12:23:55] <SpeedEvil> Jymmm: A sculling oar powered by the same drill would have _lots_ more thrust
[12:24:54] <Jymmm> =)
[12:25:38] <Jymmm> SpeedEvil: weedwacker kayak? https://www.youtube.com/watch?v=OEige-SRBds
[12:27:11] <SpeedEvil> Jymmm: http://www.simplicityboats.com/yulohstoveengine.htm
[12:28:02] <SpeedEvil> No, a sculling oar.
[12:28:19] <Jymmm> SpeedEvil: tl;dr but sorry no goat skins available
[12:28:27] <SpeedEvil> https://www.youtube.com/watch?v=cQVimIrdfik
[12:28:33] <gregcnc> https://youtu.be/XKXe8I_wTRU that's no kayak
[12:29:12] <SpeedEvil> Jymmm: that happens to be a steam engine - you'd just need a simple gear to go to ~60RPM and a crank
[12:29:30] <Jymmm> SpeedEvil: ....and goat skins
[12:29:38] <SpeedEvil> From a drill, I mean
[12:31:30] <Jymmm> ah, I really never seen a sculling oar, though I know it has something to do with backandforth to a fwd momentum thing
[12:31:54] <SpeedEvil> Boat propulsion pushes water back generally.
[12:32:14] <SpeedEvil> If you push a kilo back at 10m/s, or ten kilos back at 1m/s - you get the same thrust.
[12:32:30] <SpeedEvil> But the second can use 1/100th the energy
[12:32:31] <gregcnc> at zero speed
[12:32:41] <Jymmm> Man, that thai boat really moves!!!
[12:32:58] <SpeedEvil> If you actually only want to go at 0.5m/s - then this is a good thing and uses lots less poer
[12:33:03] <SpeedEvil> power
[12:33:25] <gregcnc> https://youtu.be/3KaKOcAERbw
[12:33:55] <SpeedEvil> turbine boats are sillier
[12:34:22] <Jymmm> gregcnc: The whining would just annoy me to no end
[12:34:34] <SpeedEvil> https://www.youtube.com/watch?v=vgDEhLj_ySw
[12:34:46] <Jymmm> gregcnc: like a 10hp mosquito buzzing around your head
[12:34:52] <CaptHindsight> not as silly as turbine water shoes
[12:35:02] <SpeedEvil> teardown of a jet turbine for a boat
[12:35:41] <gregcnc> That guy halso has some river racing on his channel irc
[12:37:40] <SpeedEvil> yes
[12:37:48] <CaptHindsight> https://www.youtube.com/watch?v=pkLZk2NDeU4
[12:37:56] <SpeedEvil> and lots of other fun turbine stuff
[12:38:08] <SpeedEvil> turbines are insane
[12:38:33] <SpeedEvil> especially when you consider that they are long units that have to be dissasembleable and reassembleable without rebalancing
[12:39:20] <gregcnc> Personal turbine transportation https://youtu.be/3KaKOcAERbw
[12:41:05] <CaptHindsight> Children wines boat line squat. ^^
[12:41:15] <CaptHindsight> what Google translate says anyway
[12:53:07] <Jymmm> SpeedEvil: Oh, and no strings of cow pattys either
[12:55:15] <CaptHindsight> I think the plural form of cow patty is cow patties :p
[12:56:25] <Jymmm> SpeedEvil: Interesting though (I read it), the politics that made it/the illegal suck though.
[12:58:47] <Jymmm> CaptHindsight: no shit?
[13:05:36] <gregcnc> beginnings of a bench top lathe with sub spindle? http://www.ebay.com/itm/252177165956?

[13:08:36] <_methods> hehe
[13:09:21] <CaptHindsight> this would have made English and Latin class much more fun than they were
[13:09:31] <CaptHindsight> but nooooo
[13:09:51] <JT-Shop> monkey pickle time!
[13:10:06] <_methods> puppymonkeybaby time

[13:10:55] <CaptHindsight> I wonder how many versions they tried
[13:11:16] <CaptHindsight> baby head, monkey head, puppy head etc
[13:11:47] <maxcnc> Gn8
[13:12:08] <gregcnc> i wonder who said "yeah go with that one"
[13:12:12] <_methods> hahah
[13:12:13] <_methods> who knows
[13:12:56] <CaptHindsight> Go-Daddy version
[13:13:49] <CaptHindsight> and another co was missing from this years commercials
[13:14:55] <_methods> probably the same guys that made this one lol

[13:18:33] <[cube]> quick cnc question: are spider couplings the best option out there? or is there a better alternative
[13:18:50] <andypugh> It very much dpends on the application.
[13:19:03] <[cube]> wood cnc
[13:19:10] <[cube]> homemade
[13:19:13] <andypugh> (and what do _you_ mean by spider couplings?
[13:19:27] <[cube]> i bought a used machine, just doing a bit of TLC on it while its disassembled
[13:19:38] <[cube]> http://www.pryco.com/sitebuilder/images/Lovejoy2-551x277.jpg
[13:19:51] <[cube]> it has these on it...personally they seem kinda crappy
[13:20:13] <[cube]> and i can forsee backlash problems with that rubber insert
[13:20:18] <andypugh> They have their uses. But only really absorb angular misalignment
[13:20:19] <_methods> well those crappy things run the machines that build your world
[13:20:40] <[cube]> just wondering if there's a better brand
[13:20:49] <[cube]> or higher quality part that you'd reccommend
[13:21:20] <_methods> well obviously a direct drive with no coupling would be nice but that's usually not feasible
[13:21:41] <_methods> so you need a coupling that will allow for misalignment and transfer of power
[13:22:05] <[cube]> yeah, I'm finding a few that seem to be higher quality
[13:22:06] <_methods> for small shafts they have those bellows style couplers
[13:22:09] <andypugh> This type can absorb angular and radial misalignment and has no backash, but is expensive: http://www.dipostel.fr/sites/dipostel.fr/files/accouplement-a-lamelles.jpg
[13:22:27] <[cube]> ah, very cool
[13:22:35] <CaptHindsight> http://www.slideshare.net/yeswanthkumarreddy1/design-of-keys-and-couplings start with frame 34 or so
[13:23:00] <andypugh> Then there are these: http://www.ruland.com/ps_couplings_flexible.asp#about
[13:23:27] <andypugh> I tend to avoid couplings and use toothed belts.
[13:23:35] <[cube]> yeah I've got similar ones to those on my 3d printer
[13:23:55] <_methods> yeah those are the bottom of the barrel lol
[13:24:14] <[cube]> im not too concerened with fine accuracy as this machine is quite large and its only going to be for wood stuff
[13:24:19] <_methods> they have a tendency to fail pretty easily
[13:24:23] <andypugh> These: http://uk.rs-online.com/web/p/products/8100710/?grossPrice=Y&cm_mmc=UK-PLA-_-google-_-PLA_UK_EN_Pneumatics_And_Hydraulics_And_Power_Transmission-_-Power_Transmission_-_Couplings&mkwid=sHAGBGZbR_dc%7Cpcrid%7C88057053603%7Cpkw%7C%7Cpmt%7C%7Cprd%7C8100710&gclid=CMTmy6my8MoCFSoEwwodnbwHdw
[13:24:25] <[cube]> but i'd like some nice mid-range couplers
[13:24:34] <[cube]> thansk CaptHindsight I will read it
[13:24:35] <_methods> then the lovejoy style is the way to go
[13:24:43] <andypugh> Couplings is a complete technical subject all of its own.
[13:24:45] <_methods> a nice compromise between cost and function
[13:24:52] <_methods> and accuracy
[13:25:07] <[cube]> what about these types?
[13:25:07] <[cube]> http://g02.s.alicdn.com/kf/HTB1Q_rbFVXXXXcbXFXXq6xXFXXXV/201033939/HTB1Q_rbFVXXXXcbXFXXq6xXFXXXV.jpg
[13:25:36] <CaptHindsight> http://machinedesign.com/mechanical-drives/10-tips-using-couplings-your-application
[13:25:37] <_methods> that's the same
[13:25:40] <[cube]> its not so much the style of the lovejoy ones, its they seem really spongey
[13:25:46] <_methods> it just has a diff design of spyder
[13:25:46] <[cube]> (the particular ones i have)
[13:25:58] <_methods> you can buy spyders of diff material
[13:26:04] <_methods> depending on your application
[13:26:07] <[cube]> i even see he's replaced some of the rubber inserts with self made HDPE ones
[13:26:15] <_methods> yep
[13:26:24] <CaptHindsight> 50 minute lecture on Shaft Couplings https://www.youtube.com/watch?v=uGxfchLe-_I
[13:26:51] <andypugh> Oldham Couplings have their uses: http://www.oepcouplings.com/content/oldham_couplings/oldham_couplings.html
[13:27:13] <[cube]> interesting
[13:27:32] <[cube]> that animation is showing off the extreme compensation i take it?
[13:28:14] <andypugh> Yes. They can accept radial alignment in a single element. Most couplings need two elements to absorb radial alignement.
[13:28:25] <[cube]> ah
[13:28:50] <[cube]> this is the machine btw
[13:28:51] <[cube]> http://i.ebayimg.com/00/s/NjAwWDgwMA==/z/MA4AAOSwJb9Wqlxl/$_27.JPG
[13:28:58] <andypugh> For most motor to shaft couplings I think that an Oldham is probably the right one.
[13:29:04] <[cube]> I can tell he put care into it
[13:29:14] <andypugh> It’s not a toy
[13:30:03] <[cube]> I'll see if I can find some for the a good price
[13:30:10] <[cube]> thx andypugh
[13:30:22] <[cube]> *for a
[13:31:16] <CaptHindsight> [cube]: McMaster has them sold in pieces, you get to pick the shaft dia for each end
[13:31:40] <[cube]> ah, cool
[13:31:44] <andypugh> Actually, best of all (and nobody ever does it) would be a totally rigid coupling, and removal of the front bearing from the motor….
[13:32:14] <CaptHindsight> common in generators
[13:33:31] <CaptHindsight> http://www.mcmaster.com/#standard-shaft-couplings/=112xmu3
[13:35:25] <[cube]> nice

[13:39:03] <gregcnc> BLDC rotor right on the ball screw
[13:39:13] <CaptHindsight> the Chinese don't believe in using the threaded ends
[14:32:25] <curious> hello, is there any way to use stepper motor as lathe spindle (index+openloop) ?
[14:33:23] <CaptHindsight> curious: yes but with the limitations of a stepper motor for that application
[14:35:44] <curious> the main problem i'm facing so far is that it needs 'home' and 'end' position (while i would like to make it turn continously, using just index for sync, and openloop for controlling speed)
[14:36:46] <skunkworks> curious, then you setup the step generator in velocity mode
[14:36:48] <cradek> you'll have to use stepgen in velocity mode
[14:36:56] <skunkworks> heh
[14:37:00] <curious> ahh, thanks
[14:37:15] <cradek> but if you haven't bought this yet, don't, because a stepper makes a terrible spindle motor
[14:39:09] <curious> it's ok for small by-hand turning of miniature stuff i do, and i want it to stay there because otherwise it's used for milling
[14:39:32] <curious> dc motor cannot hold position for really slo-mo milling
[14:41:22] <cradek> very true for milling
[14:41:37] <cradek> but for small diameters you usually want high speed, sometimes very high
[14:45:08] <CaptHindsight> curious: how fast is your top end?
[14:45:49] <AmsterdamJoe> it dozen matter you cant mill the inside of the clogg out with a 3-axist machine. The clogg is the fuselage of an RC plane
[14:46:26] <AmsterdamJoe> i mean, its an flying clogg not a shoe so the issue about routing the inside it moot
[14:47:05] <AmsterdamJoe> re: minibitz and xcoder (with apology 4 delay)
[14:47:06] <gregcnc> split it in half, use a lap seem to join it back together
[14:47:26] <curious> yeah, i get all that :) stepper is just there and it's main reason the 'lathe' is cnc (it's more for milling) . and it can turn about 300rpm no problems which is ok for (slow) turning of small stuff , thanks for the info about the velocity mode
[14:49:09] <gregcnc> do you have a laser scan of your foot so it fits properly?
[14:49:27] <AmsterdamJoe> not yet, and gregcnc did u read the bit about the flying clogg?
[14:49:34] <gregcnc> not yet
[14:49:39] <AmsterdamJoe> "its not a shoe"
[14:50:02] <gregcnc> link?
[14:50:21] <AmsterdamJoe> u can see my link, i didnt add the shoe project
[14:50:36] <gregcnc> where
[14:50:37] <AmsterdamJoe> http://joe.cryptobiz.directory
[14:50:51] <AmsterdamJoe> and this is my project link: http://amsterdamjoe.sdf.org
[14:51:40] <CaptHindsight> drone shoes
[14:51:58] <gregcnc> what flies?
[14:52:35] <CaptHindsight> depends, shoes that fly to put themselves away or shoes you can wear so you can fly
[14:53:14] <gregcnc> i keep hearing microwaved water is dead
[14:53:32] <AmsterdamJoe> CNC milled clogg-shaped fuselage + laser cut wings = RC aircraft
[14:53:47] <gregcnc> why clogg shape?
[14:53:52] <gregcnc> why milled?
[14:54:07] <AmsterdamJoe> to test the aerodynamic of the clogg itself
[14:54:31] <CaptHindsight> a drone duster could be handy, like a Roomba only for dusting shelves, tables etc
[14:54:54] <gregcnc> I think google or apple already patented that
[14:55:05] <gregcnc> OK why a flying shoe?
[14:55:22] <AmsterdamJoe> ull find out when it hits you in the bakc of the head
[14:57:07] <AmsterdamJoe> j/k i dont have a good reason for this decision
[14:58:25] <CaptHindsight> who has 22 or 16 mm pushbutton switches that may be ordered this late and ship today?
[14:58:26] <gregcnc> I fly models. I just don't know why you need a 5axis to make anything but the most specialized parts
[14:58:55] <CaptHindsight> does http://www.automationdirect.com ship same day?
[15:00:41] <gregcnc> mcmaster?
[15:01:03] <CaptHindsight> digikey and mouser
[15:01:24] <CaptHindsight> Steiner is local
[15:01:30] <CaptHindsight> but $$
[15:01:48] <gregcnc> do steiner they stock that kind of stuff?
[15:02:53] <CaptHindsight> yeah a few in Crystal lake as well, there is some panel co they keep stock for
[15:03:07] <CaptHindsight> but Elk Grove has it all
[15:03:11] <CaptHindsight> also Rockford
[15:03:26] <MrSunshine> isnt crystal lake the place where that dude killed people with axes ?
[15:03:29] <CaptHindsight> McMaster isn't bad for price
[15:03:40] <CaptHindsight> yeah
[15:04:07] <gregcnc> I was looking at Steiner yesterday, but didn't see you can check store stock.
[15:04:25] <MrSunshine> damn my memory is good =)
[15:04:28] <CaptHindsight> you can check stock but not by location
[15:04:44] <gregcnc> the number of times i've heard that when I say I'm from Crystal Lake.
[15:04:56] <MrSunshine> hehe =)
[15:05:12] <MrSunshine> havent seen friday the 13th since i was like 13 ... thats like 20 years ago =)
[15:05:19] <MrSunshine> but that name ... it just rang a bell =)
[15:05:27] <CaptHindsight> so they might have 22 pcs of some part but 6 in Rockford, 10 in the Grove and 6 in naperville
[15:05:50] <gregcnc> and you need 45?
[15:05:51] <CaptHindsight> yeah he actually used all sorts of things to hack people
[15:06:24] <CaptHindsight> if you order by 5pm they will have it in Crystal Lake the next day
[15:06:48] <CaptHindsight> except if it's in Rockford then it's an extra day
[15:07:07] <gregcnc> Good to know
[15:07:07] <CaptHindsight> they also deliver for free to your door
[15:07:14] <gregcnc> I could walk there
[15:07:18] <CaptHindsight> might be a minimum
[15:07:23] <CaptHindsight> $100
[15:07:51] <gregcnc> their terminal block stuff was the same as mcmaster
[15:07:58] <gregcnc> price
[15:08:16] <CaptHindsight> I don't like their counter help
[15:08:45] <CaptHindsight> know it alls that act like you are bothering them
[15:09:01] <gregcnc> oh
[15:09:02] <CaptHindsight> except for the Grove
[15:10:10] <CaptHindsight> yeah Crystal Lake and especially Rockford
[15:13:42] <CaptHindsight> ah McMaster gets pricey for illuminated versions
[15:16:06] <CaptHindsight> what happened to express shipping on ebay, hardly anyone offers it anymore
[15:16:19] <CaptHindsight> it's not even a search option
[15:17:41] <gregcnc> yeah I haven't seen it in a while
[16:22:56] <CaptHindsight> hmm some sellers still offer expedited or overnight shipping but you can't search for it anymore :(
[16:46:33] <Deejay> gn8
[16:47:31] <malcom2073> I want this for moving stuff around the shop: https://www.youtube.com/watch?v=rTnJYmk5-Is
[17:08:18] <Magnifikus> so anyone worked with ethercat yet? i still got the problem to interface a normal pc with an fpga for linuxcnc
[17:08:42] <Magnifikus> my idea is a light ethercat for register transfers on ethernet frame level between linuxcnc and an fpga
[17:08:59] <Magnifikus> that should be able to go down to 1xx µS latency
[17:09:28] <Magnifikus> yeah i know that reinvents mesa cards, but they are just too expensive for me
[17:09:34] <malcom2073> You're going to run into more of a problem with jitter than latency. Where ethercat really shines (and is actually worth the hassle of using), is when you have many devices down the line that all need realtime messages
[17:09:59] <Magnifikus> on dedicated nic with 1 to 1 wiring?
[17:10:23] <Magnifikus> on fpga i would interface the phy directly and the frame processing would be fixed timing
[17:10:38] <malcom2073> Right, but linuxcnc isn't quite that accurate on most hardware
[17:11:26] <roh> mesa too expensive?
[17:11:39] <Magnifikus> poor student :P
[17:12:02] <Magnifikus> but i got artix 7 boards :D
[17:12:04] <roh> when you cannot afford 150-200E for an interface.. where should ethercat help?
[17:12:08] <roh> eheh
[17:12:46] <malcom2073> If you have a FPGA, do all the buffering on there, and don't worry about realtime on the PC side imo
[17:13:02] <malcom2073> Or, just use ethernet, thats what mesa uses
[17:13:21] <Magnifikus> using ethernet frames should be better than mesa's udp
[17:13:51] <roh> no clue if thats supported by emc2
[17:14:02] <roh> i know the pci mesa cards are.
[17:14:12] <Magnifikus> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?EtherCatDriver
[17:14:14] <Magnifikus> looks like
[17:14:15] <malcom2073> linuxcnc*, and the mesa boards support ethernet now
[17:14:19] <malcom2073> As does linuxcnc
[17:14:23] <roh> uh. nice. impressive
[17:16:40] <Magnifikus> and pushing more rt into an fpga doesnt work so well imho, still need to close that 1ms command/fb loop
[17:18:01] <Magnifikus> but thanks for the opinion :)
[17:20:15] <Jymmm> Actually, offload ALL to the FPGA except the UI
[17:20:30] <malcom2073> yeah linuxcnc doens't work well with that
[17:20:51] <Jymmm> it could
[17:21:05] <malcom2073> It goes against the design mentality of closing the loop inside linuxcnc though
[17:21:08] <PCW> Bad idea
[17:21:35] <Jymmm> put linuxcnc core IN the FPGA
[17:22:09] <malcom2073> Nah, you can still run the trajectory planner on linuxcnc, just buffer up motion on the fpga, and have it execute it realtime
[17:22:25] <PCW> the complex parts of motion should be in the most accessible, extensible, and portable format (that means C code an a fast CPU)
[17:22:46] <PCW> also a bad idea
[17:23:46] <Jymmm> Is there THAT much dev these days?
[17:24:28] <Magnifikus> Jymmm, yeah :D
[17:24:30] <PCW> because then you need to port all the real time functions (probing, threading, rigid tapping and new things yet to be invented to a hostile development environment)
[17:24:46] <Magnifikus> because fpgas are fucking great at dumb parallel shit
[17:24:54] <Magnifikus> but suck with dynamic stuff
[17:25:12] <PCW> ( re-inventing Mach4 and its great success )
[17:25:13] <Magnifikus> atleas you would need to recompile it for each config
[17:25:51] <Magnifikus> what linuxcnc needs is an layer what it can tells commands and gets fb
[17:26:02] <Magnifikus> thats why my approach is now to use ethernet like ethercat
[17:26:28] <Magnifikus> slimmed down to single remote device and just simple value read and write
[17:27:08] <Magnifikus> so you linuxcnc with all its brains can reside on a COTS pc with low cost
[17:27:10] <Jymmm> like it's that difficult to compile
[17:27:20] <Magnifikus> Jymmm, nah just takes upto 2 hours
[17:27:25] <Jymmm> so?
[17:27:54] <Magnifikus> after you found someone who ported it over to a HDL
[17:28:30] <Magnifikus> its temping but imho it would take years
[17:29:16] <PCW> Bad design unless you need 100 MHZ PID loops
[17:29:24] <Magnifikus> haha
[17:29:29] <Magnifikus> yeah that too
[17:30:04] <Magnifikus> what can work nicely would be a zynq where you can offload alot into hardware
[17:30:07] <PCW> a CPU is just multiplexed hardware and appropriate for the slower parts of linuxcnc
[17:30:36] <CaptHindsight> zynq latency is terrible on the first gen
[17:30:51] <PCW> (better performance/cost )
[17:31:15] <Magnifikus> shouldnt be worse than a pi2
[17:31:28] <PCW> We can live with 500 usec or so of latency now so its basically a non issue
[17:31:56] <CaptHindsight> another wheel vs making a good wheel better
[17:32:12] <Magnifikus> dunno i got approx 70µS jitter and a servo time of 100-200µS with pi2 and SPI
[17:32:43] <PCW> That orange pi looked interesting with real Ethernet
[17:33:22] <CaptHindsight> yeah $10
[17:33:29] <CaptHindsight> $13 shipped
[17:33:59] <PCW> of course they may quite making it in a year or so
[17:34:25] <malcom2073> Any hardware has that concern
[17:34:41] <PCW> not really PCs are still a platform
[17:35:10] <malcom2073> There will always be pi-like alternatives, just like if they stop making a particular PC with parallel port, there will be another heh
[17:35:58] <PCW> Yeah and every one uses different SOCs
[17:36:00] <Magnifikus> they also die with community support for os's
[17:36:17] <andypugh> Why is there so much interest in moving LnuxCNC to other stuff? LinuxCNC is a motion controller that runs on a PC under Linux. Anything else is something else and might well be better done starting from scratch.
[17:36:50] <malcom2073> I'm always interested in alternatives
[17:37:02] <Magnifikus> andypugh i got a cnc in my university lab that i need to get running at "lowest" cost as a project (student)
[17:37:17] <Magnifikus> one way was to get a pc + mesa card + drivers
[17:37:17] <PCW> These dev boards are always changing to the latest poorly documented SOC
[17:37:22] <Erant> Magnifikus: I bought a Dell computer for $20
[17:37:25] <andypugh> Arduino and GRBL(?)
[17:37:42] <Erant> Magnifikus: Monitor mouse and keyboard were $10.
[17:37:48] <malcom2073> GRBL has a terrible trajectory planner (and I use the term planner *very* lightly)
[17:37:51] <Erant> In theory I could've run my CNC off that with the parport.
[17:37:58] <Magnifikus> i took now my own drivers (cost like 12$ each with 2amp 256µS drivers) + spartan3 for 30€ + rpi2 for 30€ +sd card and it runs fine
[17:38:29] <Magnifikus> oh and a day coding the fpga
[17:39:01] <Erant> How did you hook up the S3?
[17:39:09] <Magnifikus> spi at 12mhz
[17:39:09] <andypugh> malcom2073: The specification was “cheapest possible”
[17:39:21] <malcom2073> andypugh: Right, for varying definitions of "possible" :P
[17:39:49] <Magnifikus> and this setup runs now since 3 months flawless
[17:39:52] <andypugh> My latest PC and Mesa combo cost more than the entire machine that I first converted.
[17:40:22] <andypugh> But when I did that machine my hobby was making clock. Now my hobby is making CNC machines.
[17:40:25] <Magnifikus> problem is the pi2 lacks performance for the gui :D
[17:40:49] <andypugh> Magnifikus: Pi does a GUI a lot better than a Beaglbone
[17:41:06] <malcom2073> +1 for that, axis on the BBB is terrible
[17:41:13] <malcom2073> Even with backplot off
[17:41:19] <andypugh> But when I tried a Pi + RT_PREEMPT the latency was awful.
[17:41:35] <Magnifikus> its not only the gui, if you set offsets its recalculating all the code
[17:42:25] <Magnifikus> so my idea is now, i cant get spi on a normal pc
[17:42:33] <Magnifikus> so i replace it with ethernet that every pc has
[17:43:20] <Erant> andypugh: I'm curious what the expensive part was in that combo.
[17:44:02] <malcom2073> Mesa combo heh
[17:44:19] <andypugh> I already had the PC. I bought 2 x 8i20, 5i24, 7i84, 7i49, 7i73, 7i44
[17:46:35] <andypugh> PCW: Did I mention that the two-turn resolver on the 4-pole servo means that I can net hm2_5i24.0.resolver.01.angle directly to hm2_8i20.0003.angle and it all “Just Works” without that pesky bldc component
[17:48:17] <PCW> I think that BLDC motor/resolvers are meant to work that way (resolver output matches BLDC reference angle)
[17:48:41] <andypugh> I am sure they are, but it is nice to see it working.
[17:49:01] <andypugh> The other motor is 6-pole and one-turn resolver, so needs the component.
[17:49:14] <PCW> original resolver?
[17:49:47] <andypugh> Not that motor. It had an absolute encoder I never figured out, so I put a resolver on it. Not a lot of people do that :-)
[17:50:57] <PCW> I still haven't figured out the Fanuc V2 serial interface (or had time to poke at it)
[17:51:41] <PCW> so my 16M count encoder is unused so far
[17:51:57] <andypugh> Here it is in action. How to drill a long hole right through the apron for a leadscrew in exactly the right place: https://picasaweb.google.com/108164504656404380542/Holbrook#6250178892116252098
[17:53:09] <andypugh> (This probably wouldn’t work with a NEMA23 stepper)
[17:53:44] <DaViruz> that's pretty clever
[17:54:28] <andypugh> I did it that way because I don’t have any machines with enough envelope and stroke to do it a conventional way
[17:56:05] <andypugh> Unfortunately there isn’t room for my boring head, so I can’t finish-bore the ballscrew housing that way.
[17:57:23] <PCW> Thats nice, you know its aligned
[18:02:05] <andypugh> Well, yes and no. I think the bed needs work, now I have made a new gib to match the new apron. So it is only aligned in one place….
[18:02:43] <andypugh> I probably should scrape (or pay for grinding if) the bed before finish-boring,
[18:03:24] <andypugh> But I leave for skiing tomorrow, and took tonight off to cogitate about sequence of operations.
[18:05:45] <DaViruz> alpine or cross country?
[18:05:46] <andypugh> The bed-grinder I talked to wanted £950 for grinding all ways and turcite on the saddle. (Which seems pretty reasonable). The thing is I just want the outer ways of the bed ground, and the rest falls into my DIY gamut.
[18:05:54] <DaViruz> if that's even the correct terms
[18:05:57] <andypugh> DaViruz: Alpine
[18:06:16] <DaViruz> i started skiing last year. quite enjoyable!
[18:06:20] <andypugh> Though I do a bit of Alpine Touring, which is sort-of in the middle
[18:07:06] <DaViruz> it's good to have something to look forward in the winter
[18:07:17] <andypugh> DaViruz: This isn’t us, but I did this run 2 weeks ago. https://www.youtube.com/watch?v=RP8cZb45g7M
[18:07:56] <andypugh> The surprising thing is that that is actually ON-piste
[18:08:23] <DaViruz> that's pretty scary
[18:08:38] <andypugh> I found it somewhat exciting
[18:09:17] <DaViruz> a friend of mine goes to the alps every year, i think i'll join him next year if i can get in enough training this year
[18:09:33] <andypugh> Go for it anyway.
[18:09:52] <andypugh> You learn a lot faster on bigger mountains.
[18:10:18] <andypugh> You can try a lot if things out on a 5km uninterupted run
[18:11:42] <DaViruz> i guess
[18:12:14] <andypugh> You are what my skiing friends generically term “Scandiwegians” aren’t you?
[18:12:39] <DaViruz> we were headed to spain next month for enduro riding, but that got cancelled. maaybe i'll join him for austria instead
[18:13:00] <DaViruz> probably :)
[18:13:04] <andypugh> Which resort?
[18:13:16] <DaViruz> not sure
[18:14:19] <andypugh> We found a great cellar bar popular with Scandiwegians in Austria a few years ago. If only I could recall the resort.
[18:14:37] <FloppyDisk> When you come to norcal, we can head to squaw, if there's snow... need the lovely rain to return:-(
[18:15:07] <DaViruz> this winter has been quite crap for skiing unfortunately
[18:15:18] <andypugh> It’s picking up
[18:16:39] <andypugh> Heading here tomorrow: http://www.skiclub.co.uk/skiclub/snowreports/snowreport.aspx#.Vr0eecfQboM
[18:17:29] <DaViruz> skiing in the alps seems like one of those things you must try at least once
[18:17:43] <DaViruz> heck, just seeing
[18:17:45] <andypugh> DaViruz: I have skiied in Levi (-27. Too cold) and Rovaniemi (too dull)
[18:18:25] <andypugh> Half a meter forcast to fall during my holiday :-)
[18:19:26] <andypugh> DaViruz: Now role at work, cold start specialist. Looks like I will be spending a lot of time in Finland in future.
[18:20:30] <DaViruz> i'm only 1/4 finn
[18:21:55] <DaViruz> rovaniemi looked pretty dull actually. a lot smaller than my local resort, which is pretty small by our standards
[18:23:39] <andypugh> You are Billy the Fish? https://www.youtube.com/watch?v=VJGpOeWh30A
[18:24:06] <Lowridah> what's the closest thing to a fish's ass
[18:26:04] <DaViruz> that's pretty strange
[18:27:39] <andypugh> DaViruz: It’s a spoof of the football comics of my youth.
[18:28:35] <andypugh> Bizarrely it isn’t that far away from them. Apart fromone of the players being a woman of course, that would have been unthinkable.
[18:30:59] <FloppyDisk> The skiclub looks nice! Fun.
[18:32:37] <andypugh> Skiclub GB is quite an august body, been going 100 years.
[18:35:19] <DaViruz> now i'll be styck watching skiing videos all night
[19:30:37] <minibnz> dont you love it when you find hidden features.. was thinking about adding a adjustable stop to the tilting function of the vise so i could find zero easier.. only to find the vise already has one :)
[19:33:07] <minibnz> the small fly cutter seems to have enough power to push my vise off level.. i have tightened it up more this time and about to try fly cutting some bits of plastic...
[19:33:50] <minibnz> last time i did this it wasnt until i skimmed all 4 surfaces and drilled holes did i notice it was off.. was rather annoyed..
[19:34:10] <minibnz> the way i drilled the holes meant they all ended up pointing in different directions
[19:35:10] <Tom_itx> zeeshan we had a test quiz using formulas to day
[19:36:11] <zeeshan> :D
[19:36:12] <zeeshan> nice
[19:36:22] <Tom_itx> see if you can do it in SW
[19:36:41] <andypugh> minibnz: I am surprised that the vice moves when cutting plastic
[19:37:43] <minibnz> it mighth have actually moved when i tested with a chunk of aluminium right before i started on the plastic.. learnt the lesson there check and recheck it dont take long..
[19:38:03] <Tom_itx> zeeshan after i did it, i put a simulation on A between 1-4"
[19:38:10] <zeeshan> what am i looking at tom
[19:38:18] <Tom_itx> the quiz
[19:38:25] <zeeshan> i see a parametric model
[19:38:30] <Tom_itx> all the formulas need to be in place
[19:38:37] <Tom_itx> i'll give you the paramters
[19:40:28] <Tom_itx> the formula for the square is the dimension below it
[19:42:10] <zeeshan> you gave me a bunch of parameters
[19:42:12] <zeeshan> that define the sketch? :P
[19:42:17] <Tom_itx> yes
[19:42:42] <Tom_itx> label all the pieces as you see them and make it look exactly like the model
[19:42:52] <Tom_itx> sw will vary with it's labeling i suppose
[19:42:56] <zeeshan> why
[19:43:02] <zeeshan> its a parametric model :P
[19:43:07] <Tom_itx> yeah
[19:43:13] <zeeshan> thats how i normally make models?!?
[19:43:15] <Tom_itx> that's all we did today
[19:43:26] <Tom_itx> then sat around and BS
[19:43:29] <zeeshan> lol
[19:44:18] <gregcnc> models of involute gears using formula are fun
[19:48:35] <andypugh> Autodesk Inventor just does it, I did once do nearly-gears parametrically, but the built-in tool is better. it does profile-shifts for example.
[19:49:29] <andypugh> All the gears I have made to sell have been shifted, because of what they were.
[19:49:49] <gregcnc> that's convenient. I haven't added shifting to my model yet
[19:50:30] <gregcnc> but I won't be using the model to cut gears anyway
[19:51:31] <andypugh> As it happens, I don’t _need_ the model, I hob my gears. I just use the OD and depth and span across N-teeth data for jobs like: https://picasaweb.google.com/108164504656404380542/NerACar#6221244994687950658
[19:52:39] <andypugh> I shipped that to Australia based on rather vague measurements and not seeing the machine, and aparently it fitted perfectly :-)
[19:53:42] <andypugh> You can see that there is quite a shift there, the teeth are not at all the same shape
[19:54:08] <zeeshan> i usually just get mine laser cut
[19:54:10] <zeeshan> and machine the hub down
[19:54:12] <zeeshan> its so cheap
[19:54:26] <zeeshan> i'd like to make helical gears =/
[19:54:39] <malcom2073> Helicals would be pretty sweet to make
[19:54:59] <malcom2073> That's something I should youtube or
[19:54:59] <PetefromTn_> hey folks
[19:55:02] <malcom2073> for*
[19:55:06] <malcom2073> Hey PetefromTn_! How goes the move?
[19:55:16] <PetefromTn_> well it's goin ;)
[19:55:26] <andypugh> I want to make an extreme helical for a spindle encoder drive: https://picasaweb.google.com/108164504656404380542/Holbrook#6225576423109512802
[19:55:37] <andypugh> Thats a 1:1 ratio
[19:55:47] <PetefromTn_> today I finished the CNC milling I had to do and went to Lowes and bought a bunch of stuff for the upgrades I need to make in our sales agreement...
[19:56:20] <PetefromTn_> Tomorrow getting started on that stuff and this weekend will be a big work fest around here LOL
[19:56:31] <malcom2073> Nice
[19:57:25] <gregcnc> I want to write a macro to generate gears on a 4th, like the sandvik videos show, but Mod0.5
[19:57:35] <andypugh> It is a lot like a speedometer cable drive, in fact there might be an existing part out there.
[19:57:59] <andypugh> gregcnc: Why not hob them?
[19:58:15] <gregcnc> I have high speed spindle
[19:58:28] <andypugh> Hob fast :-)
[19:58:45] <gregcnc> the 4th doesn't run that fast or I'd try :)
[19:58:58] <gregcnc> https://www.youtube.com/watch?v=L18a_wfaRBE
[19:59:26] <andypugh> Have you done the calcs for mod0.5? You might be surprised how slow the balnk moves
[20:00:03] <andypugh> Pah, that’s an involute cutter! Ghastly things
[20:00:50] <gregcnc> right but the setup should be the same, you just have software gearing sindle-> 4th
[20:01:14] <andypugh> gregcnc: Have you seen my version?
[20:01:21] <minibnz> dang the vise moved again...
[20:01:37] <gregcnc> I think so.
[20:01:58] <andypugh> https://www.youtube.com/watch?v=ZhICrb0Tbn4
[20:02:16] <minibnz> 0.3' i think the only way i am going to get around this is by milling from the other direction so the force is against the fixed jay of the vise then the force will be against the stop screw not just the dovetail clamp
[20:02:35] <minibnz> the only problem with that is the swarfe gets thrown in my face :(
[20:02:51] <minibnz> have to close the door and use gcode to push the job around
[20:03:48] <minibnz> and the pass was not that big of a cut.. it was only 0.5mm deep at about 1000rpm
[20:04:18] <minibnz> feed speed of about 30mm/min
[20:05:29] <gregcnc> my interwebs are so slow today
[20:05:55] <minibnz> the cutter is about 35mm wide it was a narrow as i could set it while keeping some clearance betweent he job and arbor
[20:08:12] <gregcnc> andypugh you just need to tilt your A to the helix angle?
[20:08:23] <andypugh> Yes
[20:10:15] <gregcnc> I saw a sunderland gear planer on youtube recently. Didn't know such machines existed.
[20:10:52] <andypugh> Though with a different geometry, you can do it with compound moves. I now make gears using the same principle but a different machine with a swigning table: https://www.youtube.com/watch?v=PFTHY5U8v-U
[20:11:50] <andypugh> In theory you could swing the 4th axis on the table and move the table at the helix angle.
[20:13:11] <malcom2073> Lol that hob aint tiny
[20:13:59] <andypugh> No, another eBay surprise
[20:16:40] <andypugh> Anyway, time to leave
[20:17:00] <gregcnc> take care
[20:17:13] <andypugh> Back in 10 days. Skiing in the interim. If I am not back, it went wrong. :-)
[20:26:13] <minibnz> just saw a video of andypugh's tool changer idea.. i think i like this one better than my idead of a platter that has a ecentric track that pushes out the next tool as it rotates
[20:26:24] <minibnz> his is on a arm from the post https://www.youtube.com/watch?v=PfZwpjUs1xI
[20:27:07] <Crom> ugh just got my mt2-jt33 arbor in and found out I need a mt2-jt2 arbor grrrr
[20:30:57] <zeeshan> lol
[20:31:00] <zeeshan> didnt measure?
[20:31:31] <_methods> i hate that
[20:31:47] <_methods> i bought a set of mt3 centers and found out i needed mt2
[20:31:48] <_methods> doh
[20:32:03] <_methods> oh well now i have a set of mt3 centers for the spindle lol
[20:35:52] <gregcnc> Anyone know if these supplies are any good? German Made can't be that bad? http://www.digikey.com/product-detail/en/2904376/277-10207-ND/5253179
[20:40:02] <roh> gregcnc: you had issues with some psu?
[20:41:06] <gregcnc> I used some lucent and a meanwell that haven't been reliable
[20:41:36] <jdh> did they cost 30% as much?
[20:41:37] <gregcnc> that phoenix uno 150 is tiny and cheap
[20:42:11] <gregcnc> it cost no more than a rhino or meanwell.
[20:42:12] <PetefromTn_> jeez we are supposed to be gettin some snow and a BUNCH of cold here this weekend and into next week... SIGH
[20:59:20] <jdh> here too :(
[21:12:03] <minibnz> i hate the snow.. its so cold... the first time i went hunting in the state forrest at sunny cornner solo i had mates sending me pictures of it snowing less than 3ks from where i was camped. the first night i camped beside a decent sized and flowing creek oinly to wake at 4am to find the creek was nearly solid.. it was damn cold but once you start roaming the hills with a shotgun and rifle on your back you get warm.. mostly now i avoid t
[21:12:03] <minibnz> he cold times as the rabbits dont like the cold either...
[21:12:44] <Jymmm> my 9ft ss jacketed k-probes arrived =)
[21:14:24] <PetefromTn_> yeah I am pretty well over the cold anymore but of course you guys already know that ;)
[21:22:42] <Erant> gregcnc: http://www.galco.com/shop/Acme-Electric-Switching-Power-Supplies
[21:22:56] <Erant> These seem to be serving me reasonably well
[21:23:22] <Erant> And some of them are absurdly cheap. They've been on clearance for like 6 months now too.
[21:23:26] <PetefromTn_> I like Galco... perhaps it was the chocolat bars?
[21:23:41] <Erant> Mine, the 480W 36VDC ones, were $15 a pop.
[21:23:45] <Erant> Which is absurd.
[21:24:05] <PetefromTn_> last time I got the two sided hobby screwdriver kinda bummed me out I was looking forward to the Chocolate bar :D
[21:24:12] <Erant> Actually, I say were: http://www.galco.com/buy/Acme-Electric/DM1-3613
[21:24:14] <Erant> They still are
[21:24:24] <Erant> PetefromTn_: Aww, I didn't get a chocolate bar :(
[21:24:34] <Erant> And chocolate's my crack.
[21:25:21] <PetefromTn_> did you get the little screwdriver?
[21:25:36] <PetefromTn_> I actually have two of them laying around here somewhere
[21:25:41] <Erant> Think I got a ruler.
[21:25:46] <PetefromTn_> baah
[21:26:05] <PetefromTn_> we're gonna have to have a chat with the folks at galco
[21:26:09] <Erant> ;)
[21:26:17] <PetefromTn_> that damn chocolate bar was good too...
[21:26:38] <Erant> gregcnc: I'm not saying they're great, I haven't measured them for ripple on an oscope or anything, but they seem to power my servos just fine.
[21:27:00] <minibnz> in the wrong business :) chocolate where's the moneys at..
[21:27:55] <PetefromTn_> you can CNC your own Chocolate molds!
[21:28:47] <jfindley> PetefromTn_: Yep. Big money there, especially chocolate meme molds
[21:29:04] <PetefromTn_> meme molds?
[21:29:18] <jfindley> yeah, angry cat, banana for scale, stupid internet meme things
[21:29:21] <CaptHindsight> the problem is making molds on demand for same day chocolates
[21:29:34] <CaptHindsight> or custom chocolates while you wait
[21:29:59] <minibnz> i got two unbranded PSU's from ebay for $36each 5v 60amps for my laser so far i have not seen any problems with them the voltage regulation is pretty good. 0.05% (so 0.025v ripple) when i am hammering pwm out at 30+amps into two diodes per psu. have them staggered so they are not both on at the same time. helps with pulsing of my crystal too.. :)
[21:30:17] <CaptHindsight> but if it's not a rush then it's no big deal
[21:30:36] <PetefromTn_> everyone and everything is in a rush nowadays
[21:30:46] <Erant> Foodsafe plastic would mean you can mill them pretty quick
[21:31:00] <Erant> In fact... Hmm
[21:31:12] <minibnz> would you not be better just 3d printing then vacum forming?
[21:31:17] <CaptHindsight> PP and HDPE
[21:31:26] <Erant> I might try that, I have some foodsafe HDPE. Wonder if I could just cast chocolate in that.
[21:31:38] <Erant> minibnz: Ugh, all the ripples from 3D printing?
[21:31:39] <minibnz> that would be pretty quick on a good printer these days and the accuracy wont really matter once ou vac form a mold
[21:32:02] <PetefromTn_> yeah who wants a hairy chocolate bar :D
[21:32:21] <Erant> I dunno, even my little mill RIPS through HDPE. I bet I can beat a 3D printer by quite a bit.
[21:32:38] <minibnz> 3d printed objects are not foodsafe.. unless maybe if you use them instantly in a clean enviroment
[21:33:15] <PetefromTn_> I would enjoy 3d milling a chocolate mold in my Cinci methinks
[21:33:16] <minibnz> how flexible is hdpe would you still need to vac form after milling?
[21:33:16] <CaptHindsight> Erant: by 3d printer do you mean a FDM printer?
[21:33:35] <Erant> CaptHindsight: Sorry, I should've been specific. Yes. SLA would probably do much better.
[21:34:06] <minibnz> absolutely they are way faster and have a better resolution akin to bubble jet vs laser.
[21:34:28] <Erant> PetefromTn_: Hah. That would be adorable.
[21:34:45] <jdh> with flood coolant
[21:35:03] <PetefromTn_> adorable?
[21:35:09] <minibnz> depends on the size of the molds to be made it could be qiute good.
[21:35:54] <minibnz> you could probably do next day shipping.. ie you put them in the post/courier the next day..
[21:35:55] <Erant> PetefromTn_: Maybe not the right word... Not sure what that would be.
[21:36:07] <minibnz> depending on volume and time of order
[21:36:10] <Erant> The problem's the design.
[21:36:18] <PetefromTn_> how about wicked cool... LOL
[21:36:27] <Erant> "I want this 2D picture turned into a 3D thing."
[21:36:32] <PetefromTn_> or chocolichious?
[21:36:39] <PetefromTn_> shious?
[21:36:43] <PetefromTn_> shus?
[21:36:53] <PetefromTn_> aw hell screw it
[21:36:56] <minibnz> yeah i fyou were to do eggs you could make a eggbot that extrudes embossing on the outside of a standard egg form..
[21:37:15] <Erant> minibnz: That exists.
[21:37:16] <Erant> Sec
[21:37:27] <Erant> http://egg-bot.com
[21:37:38] <minibnz> yeah but it only draws on a shell not extrude chocolate onto a chocolate egg..
[21:37:47] <Erant> True.
[21:37:51] <Erant> But it could.
[21:37:59] <minibnz> add a paste extruder and you are nearly done..
[21:38:04] <Erant> Yeah
[21:38:19] <Erant> "Using our optional electro-kistka (hot wax dispenser) accessory...."
[21:38:30] <minibnz> paste extruder in 3d printer land can extrude chocolate though you might have to add a heater to keep it flowing
[21:38:39] <minibnz> oh nice..
[21:38:46] <Erant> minibnz: chocolate filament!
[21:39:18] <CaptHindsight> they wouldn't be like fine chocolate but you can print chocolate and corn syrup with inkjet
[21:39:42] <minibnz> yeah they have done 3d printers that do chocolate and turkey mince onto the hot glass to be cooked like a burger.
[21:40:10] <Erant> O_o
[21:40:17] <Erant> Some people have too much time.
[21:40:27] <PetefromTn_> if I had chocolate filament I would probably be there like the dog from Lady and the tramp... http://www.popoptiq.com/wp-content/uploads/2012/03/lady-and-the-tramp.jpg
[21:40:37] <minibnz> the hard part is keeping the chocolate at the right temp for it to be glass like.. i forget what the pro's call it but they spread it on to a bench to work
[21:40:51] <CaptHindsight> chocolate powder and binder plus a flash final sinter to glaze the surface
[21:41:12] <minibnz> just chocolate power.. laser to bind the choc directly.
[21:41:28] <minibnz> laser sintered chocolate..
[21:41:30] <minibnz> hmmmmmm
[21:41:42] <Erant> I'm actually seeing if I can find a CAD model of a heart now. I am going to win valentine's day with the wife...
[21:42:04] <Erant> I have some HDPE sheet, and there's always chocolate in this house :)
[21:42:09] <PetefromTn_> that would actually be REALLY cool....
[21:42:21] <PetefromTn_> why not just some aluminum and polish it?
[21:42:39] <zeeshan> man im trying to look for jewellery
[21:42:40] <zeeshan> this shit is hard
[21:42:46] <zeeshan> i cant tell when a stone is a fake or not
[21:42:52] <zeeshan> and what a normal price is for things
[21:42:55] <zeeshan> anyone got a clue?!
[21:43:48] <CaptHindsight> zeeshan: you need a crocked jeweler that you can trust :)
[21:44:10] <zeeshan> capt i bought something for 400 bux
[21:44:14] <zeeshan> and it ended up being a fake emerald
[21:44:16] <CaptHindsight> crocked/crooked
[21:44:22] <zeeshan> now somene might think im stupid cause maybe that is cheap?
[21:44:27] <zeeshan> but i dont know what the price range is..
[21:45:04] <Erant> PetefromTn_: I can do either. Not sure if you'd want slow cooling or quick cooling...
[21:45:21] <Erant> Quick cooling, I'd do aluminum for sure.
[21:46:01] <CaptHindsight> aluminum is not NSF
[21:46:03] <PetefromTn_> yeah man...
[21:46:42] <Erant> Ah
[21:46:43] <PetefromTn_> I don't see why a 3d mold machined into an aluminum block and then the cavity hand polished would cause any problems..
[21:47:44] <Erant> "When used in a food zone, aluminum alloys shall have one of the following Aluminum Association8 alloy designations or equivalent:"
[21:47:51] <Erant> 6xxx series alloys is in there.
[21:48:12] <Erant> Not 7 though
[21:48:21] <Erant> 1, 3, 4, 5 and 6
[21:48:27] <PetefromTn_> my wife is a HUGE Alice in Chains Fan.....
[21:48:51] <PetefromTn_> I'm thinking a big heart with AIC engraved in the face and contoured shape
[21:49:20] <Erant> Should be a pretty easy mold to make.
[21:49:33] <PetefromTn_> I am not all that great at 3d yet
[21:49:51] <PetefromTn_> I would want the heart to be kind of stylized...
[21:50:10] <Erant> Fair enough. I'm going to cut a few, see what works.
[21:50:18] <Erant> brb, going to check what I have laying around.
[21:50:33] <PetefromTn_> http://images.clipartpanda.com/heart-shape-clip-art-1539-heart-shape-clipart-1013tm-mix.jpg
[21:55:58] <Erant> Quick cooling might actually be good if the thing is going to be large.
[21:56:06] <Erant> Swirling the chocolate means you can make a shell.
[21:56:11] <Erant> Instead of solid...
[21:56:34] <CaptHindsight> I worked this all out a year or so ago. SLA patterns and corn starch molds.
[21:56:55] <Erant> Huh. (Why did you work it out?)
[21:57:05] <CaptHindsight> works for chocolate and gummies
[21:57:56] <CaptHindsight> how to mass produce (few 100- K's ea)custom chocolate and candies in the shortest time
[21:58:06] <Erant> Ah.
[21:58:08] <CaptHindsight> for school fund raisers and similar
[21:58:18] <Erant> Doesn't work for shelled chocolates though, only solids.
[21:58:34] <CaptHindsight> kids faces
[21:58:39] <Erant> Ah
[21:58:45] <Erant> Sure. pretty shallow molds then.
[21:59:29] <CaptHindsight> for shelled you just start with filled blanks and then add a custom face/side/surface
[22:00:08] <CaptHindsight> custom edible adult toys
[22:02:14] <CaptHindsight> https://youtu.be/qrypdAGEZBg?t=2m
[22:04:00] * PetefromTn_ tries to figure how to create that ellipse shaped dome a candy heart mold would need in CAD
[22:04:15] <Erant> loft?
[22:04:35] <CaptHindsight> download from a few sites
[22:04:36] * PetefromTn_ considers Erants good idea
[22:05:02] <Erant> Loft was a goodsend when I was designing my wife's wedding ring.
[22:05:22] <Erant> Any kind of 'organic' shape, really.
[22:05:23] <CaptHindsight> http://www.thingiverse.com/thing:40624
[22:05:23] <Erant> god*
[22:05:34] <minibnz> hmmmm gummie worms..
[22:05:45] <Erant> CaptHindsight: thingiverse tends to be STL though, and that... doesn't machine too well
[22:06:12] <CaptHindsight> no problem if you have real CAD tools
[22:06:29] <minibnz> PetefromTn_ in solid works i would make the heart profile and add a nice big fillet to the edge
[22:06:34] <CaptHindsight> STL --> NX ---> g-code
[22:06:59] <Erant> CaptHindsight: Ah, maybe. I just understood STL has some limitations on splines
[22:07:10] <minibnz> you could do better if you started with 45' corners first then you can add more fillets to curve the edge
[22:07:19] <Erant> Maybe it's just certain programs.
[22:07:45] <CaptHindsight> outline, extrude, then fillet
[22:07:59] <PetefromTn_> yeah but the fillet just does not get it done adequately
[22:08:03] <minibnz> yup capt :)
[22:08:39] <CaptHindsight> depends on how many features you want it to have
[22:09:05] <minibnz> outline extrue then spline cut your desired curve around the outline
[22:09:36] <minibnz> then you can draw your own fillet as a beezer curve that suits your needs.
[22:10:59] <minibnz> you could even break the spline up so you can add multiple curves.. one for the outside edge at the bottom of the V then one for the top v
[22:11:27] <PetefromTn_> http://imgur.com/q7lOUFF
[22:11:51] <PetefromTn_> LOFT/FILLET
[22:12:04] <CaptHindsight> or get/make a block of chocolate and hand carve it
[22:12:13] <minibnz> yeah thats the term i waslooking for.
[22:12:27] <PetefromTn_> now how would you get the letters in there?
[22:12:48] <CaptHindsight> get real heart, make mold, cast, give, divorce
[22:13:15] <minibnz> similar way draw the letters just a single line then draw the shape of the carve if you just want block letters.
[22:13:35] <minibnz> if you want a font you might have to settle for extrudecut then fille the edges
[22:13:40] <minibnz> fillet
[22:15:12] <PetefromTn_> No again stylized lettering
[22:16:10] <minibnz> opk then you draw the outline (not sure if there is a font tool in SW never had to put letters on anything) then standard extrude cut into the face then fillet the edges to look nice.
[22:17:09] <minibnz> im not sure if the depth of the letters can be made to follow the curve of the surface this way.
[22:17:50] <minibnz> yo might end up with aa deep groove in the center and shallower on the edges depending on how curved you got the surface
[22:19:07] <minibnz> you could also use the second direction in the extrude cut to get the sides of the groove on a angle in one move. you will get a tapered slot
[22:20:33] <Erant> PetefromTn_: Ooh, nice.
[22:20:56] <PetefromTn_> that is good advice..now I just gotta figure how to do it in Freecad LOL
[22:21:34] <minibnz> oh i havent used free cad sorry.. my work bought me a copy of SW and havent looked back.
[22:22:02] <PetefromTn_> Don't blame you there I have used it and its awesome.
[22:22:21] <PetefromTn_> I am gonna play with this and see if I can come up with something
[22:22:23] <minibnz> it works well with how i think about things :)
[22:22:56] <minibnz> you could just do another lofted cut around the straight sides rather than fillet, just like you did for the outside.
[22:23:26] <minibnz> sharp internal angles might smudge out to nothing though..
[22:23:37] <PetefromTn_> I know I considered that
[22:23:43] <minibnz> cool
[22:24:00] <PetefromTn_> I was planning to champfer the top of the heart so it is not so pointy in the cleft
[22:24:00] <minibnz> just trying to give you all the options i can think of.
[22:25:00] <minibnz> when you mill that the pooint will go away a little, depending on the cutter size it could end up curved
[22:25:58] <PetefromTn_> I was thinking try to cut it with an 3/16 ball endmill for the shape and 1/8 for the lettering
[22:26:16] <PetefromTn_> Heh just sold another rail on facebook
[22:26:17] <minibnz> ahhh nice you could then get that point..
[22:27:46] <minibnz> i have 1mm and 2mm ball cutters they are nice to get small stuff done would take you a week to cut your part out..
[22:27:52] <PetefromTn_> I was thinking I would be packing up the VMC here soon but I could use the extra cash for the move that is for sure...
[22:28:24] <PetefromTn_> Right now my part is 4.7 inches tall
[22:28:31] <PetefromTn_> .25 deep
[22:29:10] <minibnz> thats not too bad. wont take all that long to cut on a decent speed machine.
[22:29:45] <PetefromTn_> well my spindle is only 6k but the machine is rather quick if I want it to be
[22:30:45] <minibnz> im thinking i need to drop my microsteps and get back some power from my steppers.. wtih 1080steps per mm i think i can drop that to 4x and not notice any step size loss that should give me 270steps per mm
[22:31:12] <minibnz> 0.003mm steps should be fine :)
[22:31:33] <minibnz> shame its not an even multiple of mm's
[22:32:23] <minibnz> would let me sleep a bit better at night :P
[22:32:33] <PetefromTn_> lol
[22:36:57] <pcw_home> Microstepping does not lose power/torque (though it may be harder to generate the step pulses in software)
[22:38:11] <minibnz> thats not what i have read pcw_home.. to acheive micro stepping the coils act against each other to a degree this is different when you compare to whole steps where the coils work together..
[22:39:03] <minibnz> eg in half steps one coil is set to full power and the next is set to half power to hold the axle inbetween the full step points.
[22:39:42] <pcw_home> 1/2 stepping theoretically can have more torque but in practice resonance causes more torque loss
[22:40:21] <minibnz> http://www.micromo.com/microstepping-myths-and-realities
[22:40:26] <pcw_home> and the torque varies with state which is awful for exiting resonance
[22:41:09] <pcw_home> Yes that paper is terribly misleading
[22:42:41] <minibnz> even when i read the datasheets for how a stepper driver gets its microsteps it still makes sense to me. as one coil is holding against the other..
[22:42:49] <pcw_home> many many people read the paper and think that "incremental torque" is the same as stall torque
[22:42:58] <Erant> minibnz: Heh, my steps are 0.0001mm
[22:43:44] <minibnz> and how about when gecko the people that make stepper drivers say pretty much the same thing...
[22:43:45] <minibnz> http://www.geckodrive.com/microstep-full-step-torque
[22:43:48] <pcw_home> they are never against each other (they are at 90 degrees to one another)
[22:44:26] <Erant> PetefromTn_: What rails are you selling?
[22:45:49] <pcw_home> yes holding torque in some positions is better but if you are moving microstepping is better
[22:47:18] <Erant> pcw_home: Oh, question. Can I use the RS485 port in my 7i76 as a general purpose serial port, or no?
[22:47:53] <PetefromTn_> Erant http://i.imgur.com/OApitjc.jpg
[22:48:00] <pcw_home> theres a UART component but no simple HAL support
[22:48:25] <Erant> PetefromTn_: Holy cow that looks nice.
[22:48:46] <PetefromTn_> http://i.imgur.com/MfnkmnE.jpg
[22:49:00] <pcw_home> eventually I would like to have modbus support on the RS485 poert
[22:49:06] <Erant> Nice. How long does that take you?
[22:49:16] <PetefromTn_> http://i.imgur.com/yxIhC5I.jpg
[22:49:23] <Erant> pcw_home: Yeah, I've got my servo drivers that speak a custom ASCII protocol.
[22:49:28] <minibnz> dang thata big paralax wheel :) very nice rail
[22:49:28] <PetefromTn_> actual machine time?
[22:49:29] <Erant> Over RS485.
[22:49:40] <Erant> PetefromTn_: Including you setting up and whatnot.
[22:49:41] <pcw_home> It woud be especially nice on teh Ethernet cards to eliminate one more wire from the PC
[22:49:45] <PetefromTn_> yeah I make wheels too actually
[22:50:11] <PetefromTn_> probably close to an hour and a half total machine time including deburring etc.
[22:50:56] <FloppyDisk> PetefromTn_ that's nice.
[22:51:02] <Erant> I still want to make a receiver on my mill.
[22:51:14] <Erant> I was going to do a P22, but I can't seem to get the parts kit for it.
[22:51:56] <PetefromTn_> http://imgur.com/NjOGyl3
[22:52:07] <minibnz> i would love to make gun on my mill but it will cost me 25years if i get found with it.. yay gun laws at work :p
[22:52:14] <PetefromTn_> http://i.imgur.com/g5LP2a0.jpg
[22:52:28] <PetefromTn_> pss?
[22:52:33] <PetefromTn_> P22?
[22:52:38] <Erant> Small advantage of having moved to the USA
[22:52:40] <Erant> Walther P22
[22:54:04] <Wolf_> I’ve been thinking of doing a couple 1911’s when I get my house done
[22:54:31] <Erant> Thought about it, but hogging out that magwell seems like... a chore.
[22:54:40] <Wolf_> 80%
[22:54:49] <Erant> Yeah, I can do an 80.
[22:54:54] <Erant> But where's the fun in that :)
[22:54:55] <PetefromTn_> I kinda stay away from Firearms
[22:55:09] <Erant> PetefromTn_: These rifles air powered?
[22:55:14] <PetefromTn_> I make a bunch of accessories for them tho
[22:55:30] <PetefromTn_> yeah those are all precision Precharged Pneumatic Airguns
[22:56:33] <minibnz> i have a FX monsoon its nice but not as snice as those syters.. couldnt streatch my budget that far..
[22:56:34] <Erant> Wonder if I could make a 'receiver' for an airgun...
[22:56:39] <Erant> Probably be cheaper...
[22:56:49] <minibnz> it was my first legal rifle so i got me a nice one :)
[22:56:58] <PetefromTn_> FX makes nice guns
[22:57:25] <PetefromTn_> Airguns are not as simple to make as people usually think unless it is just a very basic model
[22:57:40] <PetefromTn_> I have built several from scratch
[22:57:44] <minibnz> now i have a problem i didnt lubricate the action quite right and i have two burrs inside behind the popet hammer stopped it cycling, and even now it loads but wont reload after firing a pellet..
[22:58:15] <PetefromTn_> in the hammer or in its bore?
[22:58:17] <Wolf_> 0% AR or 1911 would be easier then a pre-charged pneumatic IMO
[22:58:30] <minibnz> should have paid more attention to the instruction manual.. it says not to touch the trigger or the warranty is void. and that stoped me getting the grease into the right places.
[22:59:26] <minibnz> its in the bore.. right above the trigerr sear. i have purchased a new hammer and sear that helped but still wont reload with a pellet.. it happily dry fires without pellets multiple times in a row..
[22:59:57] <PetefromTn_> I would love to build a 1911 but honestly even decent ones are relatively cheap nowadays and quite good. These PCP airguns are quite expensive in comparison...generally anyways
[23:00:10] <PetefromTn_> Might I make a suggestion?
[23:00:21] <Erant> Wolf_: Huh, interesting. Any reason you say that?
[23:00:36] <minibnz> thinking the burr i cleaned up is now a divot and is catching the hammer as it comes back on the air pistion when firing.. think there is more pressure with a pellet. im am going to try and get a inside micrometer in there and see what i can see before i apply a little devcon..
[23:00:55] <PetefromTn_> ah okay
[23:01:02] <Wolf_> PCP airgun is more complex, maybe more dangerous IMO lol
[23:01:03] <minibnz> if i have to replace that part of the gun its a pain as it has the serial number on it.. that means a whole lota paperwork..
[23:01:07] <PetefromTn_> I was going to recommend trying something else
[23:01:17] <Erant> I'd consider the AR. Not sure if I fully have the Z for it, but probably if I put a riser on the column.
[23:01:23] <minibnz> oh i am happy to hear suggestions..
[23:01:57] <minibnz> the FX series is more dangerous than a normal gun... in that you cannot unload it without firing it..
[23:02:18] <Erant> What.
[23:02:20] <PetefromTn_> I have often cleaned up burred or scored bores with a simple die grinder and a piece of 1/4 inch drill rod, slot the end of the drill rod and stick a piece of emery cloth crossways in the slot and spin it inside the bore
[23:02:21] <Erant> That sounds dangerous
[23:02:47] <PetefromTn_> the monsoon is a repeater as I recall
[23:03:10] <minibnz> PetefromTn_ thats how i cleaned up the burr as far as i have. i didnt want to go too far so maybe i have not gone far enough..
[23:03:18] <minibnz> correct. its semi auto.
[23:03:24] <PetefromTn_> okay
[23:03:58] <minibnz> maybe i just need to apply a little more elbow grease and try again.. much better to go slowly than to try and put metal back :)
[23:04:00] <PetefromTn_> I did that for the guys in the race shop to clean up a bore for a boss on one of the cars and they were kinda dumbstruck
[23:04:11] <PetefromTn_> apparently they had never seen that done before
[23:04:29] <PetefromTn_> they were pretty happy with how easily it worked and how controllable it is
[23:04:48] <PetefromTn_> great way to clean up a bore and simple as dirt
[23:05:19] <minibnz> i had looked into sleeving it but there is a thread thats at the same diameter (that contains the spring) so i cant..
[23:05:34] <PetefromTn_> Well I need to get to sleep guys. Goodnight
[23:05:43] <minibnz> ok i will get the emry paper out and give it s a bit more.. thanks for the help..
[23:05:55] <PetefromTn_> yeah man be careful and go slow
[23:06:02] <PetefromTn_> Gn8
[23:06:06] <minibnz> later..
