[16:47:40] <tiwake> if I engrave overtop anodized surface, should I fill in the groove with some sort of clearcoat?
[16:47:53] <tiwake> or epoxy or something
[16:47:59] <tiwake> or just leave it
[16:50:01] <jdh> anodize it
[16:53:15] <tiwake> engrave then anodize?
[16:53:24] <tiwake> so, mask it off
[16:54:02] <tiwake> not sure how to do that
[16:54:19] <tiwake> without damaging the surface
[16:58:09] <Tom_L> clearcoat it
[16:58:41] <tiwake> is filling it in with epoxy a bad idea?
[16:59:35] <Tom_L> probably not, depends on the look you're going for
[17:00:09] <tiwake> hmm
[17:00:15] <Tom_L> http://tom-itx.no-ip.biz:81
[17:00:22] <Tom_L> i just used black paint on those lettering
[17:00:37] <Tom_L> but it's not anodized either
[17:01:00] <Tom_L> quite common to fill engraving with some sort of goo
[17:01:23] <tiwake> alright
[17:01:36] <Tom_L> ^^ was just krylon
[17:02:06] <Tom_L> just make sure it's oil free when you apply
[17:04:58] <tiwake> sure
[17:05:14] <tiwake> I think a tiny ball endmill would look good
[17:05:23] <tiwake> like 1/16 or something
[17:06:05] <Tom_L> no, i'd get engraving bits
[17:06:22] <Tom_L> you can try it i suppose ymmv
[17:06:29] <tiwake> engraving tools leave a square bottom don't they?
[17:06:33] <Tom_L> no
[17:06:41] <Tom_L> mine are 60deg? points
[17:07:07] <tiwake> point, but the point is off center? so it leaves a square bottom
[17:07:30] <Tom_L> mine have something like a .001" flat maybe
[17:07:37] <Tom_L> https://www.amazon.com
[17:07:41] <tiwake> maybe not then
[17:08:06] <Tom_L> those are slightly different than mine. mine are half round
[17:08:28] <tiwake> 0.004" bottom then
[17:08:32] <tiwake> (for those)
[17:08:46] <Tom_L> i didn't check but likely so
[17:08:56] <tiwake> says 0.1mm tip
[17:09:15] <Tom_L> https://www.ebay.com
[17:11:36] <Tom_L> just get the feeds etc right or you'll chip the end off
[17:13:16] <Tom_L> you can get them with wider points if you want
[17:14:02] <Tom_L> or wider angle

[17:52:46] <transhumanist> anyone know where I can get a good CNC gantry CNC mill frame including a real nice ball screw and good accuracy. I wanted to hand pick and choose parts for one ... something like this only one that takes a real nice accurate and big ball screw and is finely machined: https://www.ebay.com
[17:53:20] <transhumanist> only other complaint I have about this one besides worries for accurate machined parts is that the verticle hight isnt as high as I would hope

[18:06:52] <pink_vampire> XXCoder: ?
[18:12:00] <andypugh> SpeedEvil: I have seen omniwheel versions of that loading cargo into a plane. (I was looking out the plane window)
[18:13:23] <andypugh> transhumanist: Which country are you in and how much money are you prepared to trade for your time>
[18:13:27] <andypugh> ?
[18:14:31] <andypugh> I gues that most of us here would either build from scratch or buy the cheapest possible thing from China to be viewed as a kit of parts.

[18:15:21] <Tom_L> pink, your invention or you found it that way?
[18:15:27] <andypugh> (Though I bought a kit-of-parts 3D printer from China and I am still running it unmodified 4 years later)
[18:15:44] <pink_vampire> I did it
[18:16:31] <andypugh> pink_vampire: Needs an actual 7 pink jewels in the face :-)
[18:17:38] <pink_vampire> I think it's the 5th time that I took it a part, apparently gravity work.
[18:17:56] <andypugh> Or maybe (7 + 4) Jewels as tha text and shiny things at the cardinal points.
[18:18:14] -!- asdfasd1 has quit []
[18:18:48] <transhumanist> sorry was pulled away
[18:18:53] <transhumanist> not sure what yoiu mean andypugh
[18:18:55] <pink_vampire> it took me about 5 minutes to paint it pink with the airbrush and half a drop of pink acrylic paint.
[18:19:00] <transhumanist> I live in the usa
[18:19:32] <Tom_L> transhumanist, can't find any used iron to convert?
[18:19:45] -!- syyl has quit [Quit: Leaving]
[18:20:08] <pink_vampire> Now I just need a pink caliper and pink micrometer
[18:20:24] <Tom_L> my calipers are blue
[18:20:26] <transhumanist> I guess i i will go for a fully assmebled version of the one I just posted to start with I just worry about lack of accuracy
[18:22:25] <transhumanist> I would like to find something very similar with a bigger bed and more verticle clearance, few fit in this category
[18:22:49] <andypugh> transhumanist: That cast iron frame does look like a decent starting point. You have notied (I think) that it needs slides, balsscrews etc.
[18:23:30] <andypugh> Are you particulary constrined by space?
[18:23:33] <transhumanist> yes and from what i understand picking out the ball screw might be the biggest critical piece besides the wattage of the miller
[18:23:49] <transhumanist> wood and soft metal machining
[18:24:41] <andypugh> Is there no way that you can find a home for an actual milling machine? That money will buy you an already working machine
[18:24:47] <transhumanist> but if its got a lot of variability on the quality of the machined parts. its not much good
[18:25:30] <transhumanist> yes space is an issue
[18:26:05] <transhumanist> I would like to machine within a thousandth of an inch if possible
[18:26:59] <transhumanist> andypugh I hope your around later, I will come back to talk but cant talk much longer
[18:27:19] <transhumanist> are you around a lot?
[18:27:26] <XXCoder> hey pink_vampire
[18:27:55] <XXCoder> lol nice
[18:28:28] <andypugh> transhumanist: I am on fairly often, but not as much as I used to. And like on insomniac GMT + )
[18:29:04] <andypugh> (live on insomniav GMT + 0) I meant to say
[18:29:06] <transhumanist> ok andypugh thanks, if you across one that you think might fit the bill, can you message me?
[18:29:23] <andypugh> transhumanist: https://www.ebay.com
[18:29:57] <transhumanist> wow that is way to big almost as big as my dads bridgeport
[18:30:16] <andypugh> Yes,
[18:30:57] <andypugh> You seem to be shopping for your first CNC machine,
[18:31:05] <transhumanist> yes
[18:31:33] <andypugh> Buy something really cheap, and possibly nasty, and learn from that what you really need.
[18:31:43] <transhumanist> ok thanks andypugh
[18:32:54] <andypugh> Something like the 6040 machines.
[18:33:01] <pink_vampire> XXCoder: thanks!!
[18:33:10] <XXCoder> but not too far down, yeah 6040 is pretty good
[18:33:16] <andypugh> which at least work out of the box
[18:33:38] -!- Connor has quit [Quit: Leaving.]
[18:33:47] <XXCoder> i prefer more black dial and white arm but price tend to jump up on those lol
[18:34:13] <pink_vampire> I can make you any color you want.
[18:35:00] <XXCoder> its fine i have long since used to stock colors
[18:35:04] <andypugh> To put this in perspective, my first machine I bought for conversion was a £700 mill / lathe combo which turned out to be a terrible mill, a decent lathe and an ecellent learning experience,
[18:35:39] <pink_vampire> just pop the glass, remove the arm, pssss psss with acrylic airbrush and you have it
[18:35:44] <andypugh> My most recent conversion cost me more than that just for the custom castings I had cast :-)
[18:35:58] <transhumanist> I see
[18:36:34] <transhumanist> well I kinda have an idea from college work what I am looking for, whats in that image I posted except for verticle clearance and accuracy it fits the bill
[18:36:35] <andypugh> You might find that a 6040 (with the stock software even) will do all you need.
[18:37:15] <andypugh> or you might find that you need far more, and eve LinuxCNC isn’t good eniugh for you.
[18:37:31] <Tom_L> why a gantry design?
[18:37:43] <transhumanist> well I was looking at verticle mills
[18:37:44] <andypugh> Yesm good question
[18:38:13] <Tom_L> i built a vertical
[18:38:14] <transhumanist> that one seemed to have the most mass of any of the cheap cnc's
[18:39:07] <andypugh> That little gantry does have a jig-mill look. WIth half-decent ballscrews, _very_ good linear encoders and LinuxCNC you could make that into a super-precision small mill,
[18:39:35] <andypugh> But he said he wanted 1 thou, not sub-tenth
[18:40:46] <andypugh> If I wanted to machine watch plates then that frame (with work, like hand-scraping the ball-slide seats) might be a good starting point.
[18:41:43] <transhumanist> ok andypugh good enough I guess I will go with it then
[18:42:11] <andypugh> Don’t get me wrong, I already admitted to spending about that much for new iron castings for a machine that already existed,
[18:42:43] <transhumanist> I will see if I can get one that is fully assembled with good parts to start with. I would like to use it as a stepping stone to building larger more prcecise equipment
[18:42:52] <transhumanist> I can use electropolishing if I have to
[18:43:09] <Tom_L> just depends where you're willing to give and take. precision, size etc
[18:43:19] <transhumanist> ya I know
[18:43:38] <Tom_L> good rails and screws will cost more than that frame
[18:43:51] <Tom_L> i settled for china grown ones
[18:43:57] <Tom_L> works fine for me
[18:44:04] <andypugh> If you think that electropolishing and hand scraping achieve the same ends, then you have a lot to learn, young padawan. (And a fun journey ahead of you)
[18:44:17] <Tom_L> heh
[18:44:42] <transhumanist> I see
[18:45:40] <andypugh> Niow who was it I watched on Yotube scraping in a mill? He went really deeply into what he was referencing to what.
[18:45:54] <transhumanist> this one seems interesting , any thoughts? https://www.ebay.com
[18:45:55] <transhumanist> wcB
[18:46:26] <Tom_L> i knew a russian chap in another channel that was building a lathe. last i heard from him he was still scraping the surfaces
[18:46:50] <transhumanist> lol ok got it
[18:47:16] <Tom_L> i built my whole mill and afik he's still scraping :)
[18:47:47] <Tom_L> i had a budget
[18:48:09] <Tom_L> and used what i had available locally except screws, steppers etc
[18:48:23] <andypugh> transhumanist: That ebay design is terrible, but you couldn’t buy the parts for that price.
[18:48:47] <transhumanist> thats a real interesting one, problem is I dont know what model it is, nothing comes up for the actual model thats fully together
[18:49:03] <Tom_L> now if i were andy, i'd have cast the frame and had it ground :)
[18:49:16] <Tom_L> then scraped it
[18:49:21] <andypugh> Ah! The auction is _only_ for the extended Z axis
[18:49:29] <transhumanist> Yes I know
[18:49:34] <transhumanist> cant find the actual cnc itself
[18:50:12] <andypugh> As I said, that actual CNC is a rather bad design,
[18:50:48] <transhumanist> ah ok
[18:50:50] <Tom_L> i haven't seen any of those aluminum box mills but i can't imagine them being that rigid
[18:50:57] <transhumanist> I see
[18:52:19] <Tom_L> what do you plan to cut with it?
[18:52:20] <andypugh> Why are the ballscews up so high (arguably they are near the cutting force, so that’t one argument, to reduce moment loads (torques) but they are in the way of all the dust. And the gantry is thin at the bottom where all the loads are
[18:52:22] <XXCoder> it reallys falls under what usercase is. what are you milling
[18:52:56] <transhumanist> want to machine wood plastic and aluminum
[18:53:51] <transhumanist> what do you think of this one? https://www.google.com
[18:54:13] <Tom_L> little z travel
[18:54:22] <Tom_L> if you put a vise on it you won't have room for much else
[18:54:29] <andypugh> I think I could make that cast iron frame into a lovely little machine. But I could also make my own patterns and have them cast by a foundry for half the price. But that’s fair, you are pauing for theor design, machining and the paint.
[18:54:34] <transhumanist> ya I was thinking may be the same thing
[18:54:36] <XXCoder> yeah can use drill vise but yeah qyite tight
[18:54:58] <XXCoder> https://www.ebay.com interesting
[18:55:03] <Tom_L> i ended up raising mine up another 2" once i realized the same
[18:55:40] <transhumanist> ya I was looking at that one, just didnt seem to be all that "stiff"
[18:56:00] <transhumanist> interesting the motor is offset to side
[18:56:08] <Tom_L> http://tom-itx.no-ip.biz:81
[18:56:15] <Tom_L> that's what i came up with and built
[18:56:28] <Tom_L> suits my needs and made from material i could find here
[18:56:34] <andypugh> The little gantry originally suggested is east to jack up for more Z height
[18:56:39] <transhumanist> wow thats nice, feel like sharing the plans?
[18:56:53] <Tom_L> it's all catia
[18:56:58] <transhumanist> andypugh: how would I do that ?
[18:57:35] <andypugh> It just needs some blocks under the gantry legs,
[18:58:30] <Tom_L> http://tom-itx.no-ip.biz:81
[18:58:33] <transhumanist> ah you think that can be raised up then, intersting
[18:58:38] <Tom_L> not pretty but it works well
[18:59:21] <transhumanist> so you think the vertcile two pillers come unattached>?
[19:00:04] <Tom_L> one way or another :)
[19:00:15] <andypugh> I like the cast iron frame, but it isn’t a working machine. But it has the potential to be superb. But you would need another machine to make the parts. How about buying a _lathe_ with a milling slide. Or do you have a lathe>
[19:00:27] <transhumanist> lol cut the damn things, I didnt realize that was affective with cast iron to be honest
[19:00:42] <transhumanist> yes i have access to a lathe
[19:01:17] <transhumanist> and a big bridgeport and some cutting tools but only for a day or two a week before I start bugging the hell out of my dad
[19:01:27] <andypugh> You can see the join where the legs meet the base
[19:01:47] <XXCoder> interesting spindle cooling solution
[19:01:53] <transhumanist> ah right
[19:02:24] <Tom_L> XXCoder, it's the stock sherline spindle
[19:02:39] <XXCoder> you probably can use car radator for cooling fluid
[19:02:40] <Tom_L> and i tend to push it
[19:02:42] <transhumanist> ok then I like yor input , glad I came and risked looking like a fool to ask!
[19:03:09] <Tom_L> XXCoder, if i'm machining something that needs alot of material removal i'll add ice to the bucket
[19:03:20] <Tom_L> quite effective
[19:03:37] <XXCoder> yeah. though if you use car radator setup you could just use car fan and such
[19:03:45] <XXCoder> using some 12v input
[19:03:54] <Tom_L> do you honestly see room for a car radiator there?
[19:03:56] <Tom_L> :)
[19:04:01] <XXCoder> yeah
[19:04:05] <transhumanist> I know someone who lives very close to where they are selling that for 1000 bucks only an hour a way. I can ask them to pick it up , they are going to be driving up north in a few weeks anyway
[19:04:09] <XXCoder> on wall :) where hose crosses
[19:04:33] <Tom_L> not as much room there as you think
[19:04:33] <XXCoder> or maybe heater core
[19:04:37] <transhumanist> not bad for $1000 I guess
[19:04:41] <Tom_L> that might be more like it
[19:05:19] <andypugh> transhumanist: https://www.youtube.com
[19:06:06] <andypugh> It’s just photos and commentary, but very good at explaining what is referenced to what and why
[19:07:00] <andypugh> And would be a good starting point for checking that little cast iron machine if you did buy it
[19:08:14] <andypugh> You could just buy it, bolt in the cheapest parts that you can find and _then_ inspect and updrade,
[19:08:55] <transhumanist> oh thanks andypugh, I did not bother to look at the base of the mill I was looking at the top and it didnt seem like it would separate easy, but looking at the bottom I see you are right
[19:09:59] <transhumanist> I have to run now. I think the hard part will be finding a good ball screw for it. Not sure really what to look for but I guess i will learn
[19:10:24] <andypugh> I do think that it could make a lovely little machine.
[19:10:42] <transhumanist> wish I knew what the model is of the gantry, I dont see but a couple of them
[19:11:19] <andypugh> Buy the cheapest _preloaded_ ballscrew you can find, You can sort out the accuracy in software
[19:11:28] <transhumanist> ok
[19:11:34] <transhumanist> thanks for the advice
[19:12:36] <transhumanist> I will catch up with you later
[19:13:22] <andypugh> One other video, this is a machine using worn leadscews that are laser mapped then compensated in LinuxCNC. https://www.youtube.com
[19:14:09] <transhumanist> interesting , thanks
[19:14:09] <andypugh> After 3 mins you see what an utter monster it is, ]
[19:15:20] <transhumanist> thanks!
[19:17:04] <andypugh> `That’s holding 1 thou while doing 5 axis moves with leadscews,
[19:17:33] <SpeedEvil> andypugh: neat
[19:17:37] <tiwake> why not just replace the ballscrews if they are worn?
[19:18:01] <andypugh> They are about 30’ long and 5” diameter?
[19:18:34] <tiwake> sure
[19:18:36] <tiwake> just do it
[19:19:37] <tiwake> thats cool though... linuxCNC can correct such things?
[19:19:47] <andypugh> Yes
[19:21:33] <andypugh> And that machine is possibly a rare case where backlash comp probbaly does work, the bed is so heavy that cutting forces don’t move it around the backlash.
[19:21:57] <Loetmichel> jymmmm: pong

[21:05:42] <CaptHindsight> type 2: up/down
[21:05:42] <CaptHindsight> Two output pins, up and down. For positive inputs, the PWM/PDM waveform appears on up, while down is low. For negative inputs, the waveform appears on down, while up is low. Suitable for driving the two sides of an H-bridge to generate a bipolar output.
[21:07:22] <CaptHindsight> this is for software PDM
[21:08:29] <CaptHindsight> ah found the hardware version http://www.linuxcnc.org

[23:27:45] <veegee> I bought the Acer 1440V and unloaded into my workshop. Going to wire it up tonight
[23:27:59] <veegee> I have chucks and stuff but no cutters yet.
[23:28:31] <veegee> Can't wait to try it. I have some HSS blanks so I can grind my own tools, but I'd rather start with something standard. Any recommendation for a first cutter?
[23:28:53] <Tom_L> lathe?
[23:28:55] <veegee> yes
[23:29:00] <Tom_L> get some insert holders
[23:29:16] <veegee> I know almost nothing about using a lathe
[23:29:53] <roycroft> when i took machining classes we spent two sessions learning how to grind drills and lathe cutters before we were ever allowed to touch a machine
[23:29:53] <XXCoder> of course you must use lathe rook https://www.youtube.com geg
[23:30:04] <XXCoder> *pawn *heh
[23:30:20] <roycroft> and i'm grateful for that
[23:31:45] <Tom_L> https://www.ebay.com
[23:31:47] <Tom_L> or such
[23:32:12] <Tom_L> right, left, center and cutoff
[23:32:55] <Tom_L> find what fits yours
[23:33:13] <Tom_L> different center heights
[23:33:45] <Tom_L> and a set of boreing bars
[23:35:41] <Tom_L> live center if you didn't get one
[23:36:29] <Tom_L> that's kindof a bare bones get you started suggestion
[23:37:12] <roycroft> some lathe dogs would be useful so you can turn between centers
[23:37:59] <roycroft> in fact, you can't set up the lathe properly without that ability
[23:38:42] <Tom_L> it's a never ending list...
[23:38:59] <roycroft> the machine is but a small part of the cost
[23:39:09] <roycroft> it's the tooling and fixtures that are the real money
