[00:00:01] <zeeshan> okay that is similar to the siemens motors
[00:00:04] <zeeshan> that are on my machine
[00:00:07] <enleth> $1500 used with encoder, good condition
[00:00:32] <enleth> $500 with no encoder and a little beat up
[00:00:33] <djdelorie> wait... your Z is on your table? and not your quill? and you're *peck drilling* with it? no wonder you're blowing fuses!
[00:01:01] <zeeshan> djdelorie: lol
[00:01:14] <zeeshan> djdelorie: it worked for a very long time
[00:01:22] <zeeshan> and last couple of days ive blown two fuses =/
[00:01:33] <enleth> there are some units below $500, so it may be possible to get a set of 3 below $1000
[00:01:33] <zeeshan> (long time = 1+ year of running the machine)
[00:01:52] <zeeshan> enleth i think if these motors blow it might be easier to get them rebuilt
[00:01:58] <zeeshan> i got quored 550 to rebuild the Z axis
[00:02:01] <zeeshan> *quoted
[00:02:11] <zeeshan> and they have the siemens test equipment to check its functionality
[00:02:20] <enleth> I just found one slightly bigger than mine for $300
[00:02:32] <enleth> like, slightly longer and more torque
[00:02:35] <enleth> otherwise identical
[00:02:44] <enleth> that's a very nice deal
[00:03:28] <enleth> SEM is still in business so I guess they might be able to rewind their motors as well, but I don't know their repair prices
[00:04:08] <enleth> anyway if you need the machine fixed now you buy a used similar motor off ebay anyway
[00:04:30] <enleth> the old one ends up a spare when it comes back from rewinding
[00:04:30] <zeeshan> yea
[00:04:45] <zeeshan> what happened to your motor?
[00:04:52] <zeeshan> that made you take it apart
[00:05:17] <enleth> the one that died? that was a different one, much smaller
[00:05:23] <enleth> bearing seized up
[00:05:48] <enleth> so I decided to replace it and go figure, the bearing stopped being my biggest concern
[00:06:14] -!- anth0ny has quit [Quit: anth0ny]
[00:06:35] <enleth> next time I need to replace a bearing in a valuable DC motor, I'm only going as far as pulling the end plate off
[00:06:39] <enleth> the rotor stays in
[00:07:49] <zeeshan> hehe
[00:08:38] <enleth> with some paper packed around it so it stays centered
[00:10:32] <Sync> depending on the motor it actually is not too much of an issue

[00:45:10] <zeeshan> :P
[00:47:04] <malcom2073> Holy hell that's an expensive freaking resistor
[00:47:11] <zeeshan> mostly the casing
[00:47:14] <zeeshan> and mounting youre paying for
[00:47:51] <malcom2073> Eh I suppose
[00:47:58] <malcom2073> I'd call that a $20 case
[00:48:13] <malcom2073> Yeah, I guess $100 is about right
[00:48:21] <zeeshan> brand new its 223

[01:53:41] <pink_vampire> I like the way that the metal feel after the anodize
[01:53:52] <BeachBumPete> still house hunting
[01:54:49] <BeachBumPete> however we did make it to the beach today and bought my kids some new boogie boards ;)

[01:59:56] <pink_vampire> zeeshan: is was you that make anodize at home?

[02:00:14] <zeeshan> =D
[02:00:16] <zeeshan> hehe
[02:00:30] <zeeshan> man i usually can run the 3" saw at 30 ipm
[02:00:38] <zeeshan> but this big guy keeps spinning in my holder cause no key
[02:00:42] <zeeshan> or itll stall the motor
[02:00:47] <zeeshan> cause the speed is too slow
[02:01:09] <pink_vampire> one of you guys told me that he do it.. so because of him I start to do it also.
[02:01:16] <zeeshan> pink_vampire: pete does it
[02:01:53] <pink_vampire> anyway, I want to thank him!
[02:02:02] <BeachBumPete> does what?
[02:02:17] <BeachBumPete> oh anodize
[02:02:30] <zeeshan> skunkworks: check this out
[02:02:49] <BeachBumPete> yeah I did it for my rails unless I had a lot of parts to do then I took it to the pro shop nearby

[02:03:11] <BeachBumPete> now that I am down in Florida I need to find a local anodizer shop again
[02:03:31] <BeachBumPete> I also need to find a good argon gas supplier and metal supplier and and and and
[02:04:11] <zeeshan> duc that looks like he changed the source code :P
[02:04:17] <skunkworks> looks nice
[02:04:47] <Duc> zeeshan: dam would be nice to change some other stuff on the fly
[02:04:59] <pink_vampire> what is the best way to finish the aluminum before anodize?
[02:05:20] <pink_vampire> sand blast? tumbler?
[02:05:31] <BeachBumPete> I liked the brush finish I was putting on most of them
[02:05:34] <gregcnc> depends on what you want it to look like
[02:05:46] <BeachBumPete> I did a bunch of bead blasted as well
[02:06:12] <Duc> a teflon coating helps turn things blacker or appear more black
[02:06:14] <pink_vampire> BeachBumPete: how do you brush it?
[02:06:26] <zeeshan> duc
[02:06:27] <zeeshan> nm
[02:07:02] <zeeshan> Calibration reads the HAL file and for every 'setp' that uses a variable from the ini file that is in an [AXIS_n] section it creates an entry that can be edited and tested.
[02:07:06] <BeachBumPete> well I usually took some wet or dry sandpaper and moistened it and set it on top of my tablesaw table and run the part back and forth in a straight line over it.

[02:09:15] <Duc> zeeshan: do you have a link where you found the info
[02:09:22] <gregcnc> oops i didn't expand the comments
[02:09:33] <zeeshan> im going to find out if 0.002" deflection is acceptable
[02:09:37] <gregcnc> my parts are usually much smaller so it looks like a tiny cut
[02:09:40] <zeeshan> everywhere i read they say not to exceed 0.001
[02:10:48] <zeeshan> https://github.com/LinuxCNC/linuxcnc/blob/2957cc5ad0a463c39fb35c10a0c14909c09a5fb7/docs/src/gui/axis.txt
[02:11:22] <gregcnc> that ramp on the counterbore needs to start closer to the part
[02:11:51] <zeeshan> yes
[02:11:56] <zeeshan> and the slitting saw needs the tool path optimized
[02:12:00] <zeeshan> its doing a lot of air cutting
[02:12:42] <gregcnc> i couldn't stand watching more than 10 seconds of the saw
[02:12:46] <zeeshan> haha
[02:12:51] <zeeshan> its so slow
[02:13:10] <gregcnc> you'd be brave to run much faster
[02:13:15] <zeeshan> i tried
[02:13:17] <zeeshan> it jams
[02:13:35] <zeeshan> i think if i had a key and i geared the spindle right
[02:13:37] <zeeshan> it could work
[02:13:58] <zeeshan> it should be running at 20 ipm for optimal chip thickness
[02:15:02] <gregcnc> the parts look good
[02:15:21] <zeeshan> thanks man

[02:17:14] <zeeshan> gregcnc: what kind of vise do you have?
[02:17:15] <Duc> Might be time to by a used fanuc robot off ebay to load that sucker
[02:17:19] <gregcnc> shitty
[02:17:23] <zeeshan> my el cheapo vise is no good
[02:17:30] <zeeshan> even though the jaw is fixed
[02:17:46] <zeeshan> for some reason if i remove a part and put it back in, the part center line shifts
[02:17:51] <gregcnc> I have a Kurt PT400 but it doesn't fit my puny emco
[02:18:02] <zeeshan> and i think its because of variable clamping force
[02:18:11] <gregcnc> torque wrench
[02:18:33] <zeeshan> i was thinking about that
[02:18:42] <gregcnc> many people do it and see results
[02:19:18] <zeeshan> gregcnc: apparently good vises like the orange vise don't suffer from this problem
[02:19:23] <Duc> torque wrench will make a difference can you get a kurt or orange vise
[02:19:24] <zeeshan> and i don't really see how they do it
[02:19:41] <gregcnc> does your moving jaw lift?
[02:19:45] <zeeshan> no
[02:19:49] <zeeshan> ive measured it
[02:20:32] <zeeshan> i put an indicator on the moving jaw

[02:21:29] <Duc> AL jaws or steel?
[02:21:32] <zeeshan> steel
[02:21:38] <Duc> harden?
[02:21:41] <zeeshan> yes
[02:22:19] <zeeshan> to be honest i really never paid attention to how much torque i was applying
[02:22:25] <Duc> i should test mine
[02:22:51] <gregcnc> so it closes more when you put it back in?

[02:35:28] <zeeshan> they reduce z height and they always move!
[02:36:07] <Nick001> any dents or nicks on the bottom of the vise.
[02:36:18] <zeeshan> no

[02:36:33] <Encapsulation> what do you need
[02:36:33] <Encapsulation> =D
[02:37:17] <pink_vampire> I'm using 2% caustic soda solution before the anodize.
[02:37:24] <Nick001> still sounds like its flexing under clamping pressure
[02:37:42] <zeeshan> Nick001: indicator on the fixed jaw shows no movement
[02:37:52] <zeeshan> in which direction do you think its flexing?
[02:38:29] <pink_vampire> but it make the part black
[02:39:01] <Nick001> the solid jaw has to be moving if you keep shifting center of part.
[02:39:03] <pink_vampire> now in the anodize solution the black cove come off and float in the acid.
[02:39:19] <zeeshan> hm
[02:39:28] <pink_vampire> any idea how to solve it?
[02:40:09] <Nick001> how tight ar the gibs and is the saddle clamped?

[02:40:55] <zeeshan> because if i dont remove the part from the vise and do all the operations
[02:40:55] <Nick001> BTW - what mill are you using?
[02:41:03] <zeeshan> it doesnt have that 0.006" shift
[02:41:11] <zeeshan> mikron wf21c
[02:42:21] <Nick001> got a pic - vertical ram clamped?
[02:42:23] <zeeshan> Nick001: since i measured the moveable jaw moving 0.006 from the original clamped place
[02:42:32] <zeeshan> do you think im actually crushing the part
[02:42:35] <zeeshan> and moving the center line?
[02:42:44] <zeeshan> i mean logically to me that doesnt make sense
[02:42:52] <zeeshan> cause it takes a lot of force to crush a part 0.006!
[02:43:02] <gregcnc> that was on my mind, but esay enough to check
[02:43:14] <Encapsulation> pink_vampire, what al type you using
[02:43:19] <zeeshan> deflection = PL / AE , P = deflection*AE/L
[02:43:22] <Encapsulation> why 2% caustic soda???/
[02:43:25] <Nick001> some pics of the part and machine would help
[02:43:47] <pink_vampire> Encapsulation: 2034-t3
[02:44:10] <Nick001> thin walled alum part would move easy
[02:44:21] <pink_vampire> i'm using it as a degreaser

[02:47:14] <zeeshan> Nick001:
http://i.imgur.com/46vO9a9.jpg
[02:47:27] <pink_vampire> I did it several times.
[02:48:56] <zeeshan> looks like my vise can clamp at 12000lb
[02:49:11] <zeeshan> so that 0.006" part crushing theory is out the window :P
[02:49:26] <pink_vampire> Encapsulation: I'm trying to identify what is the black material that form on the aluminum..
[02:49:43] <zeeshan> Nick001: part is the right one:
http://i.imgur.com/aCKopff.jpg
[02:49:58] <zeeshan> i remove it a few times to do all the drilling first
[02:50:10] <zeeshan> then counterbore
[02:50:16] <zeeshan> then slotting
[02:54:09] <Nick001> nice machine. Parts are large enough to not crush or move on their own. I would have an indicator on that overhead ram and other possible loose slide elements.
[02:54:51] <zeeshan> thanks
[02:55:43] <Nick001> What is the vertical movement part of the machine? Slide with the vice or entire head moves?
[02:56:02] <zeeshan> entire head moves in the Y
[02:56:07] <zeeshan> 15.7"
[02:56:14] <zeeshan> i really dont think its a gib issue though
[02:56:28] <zeeshan> cause if i make the part without removing it from the vise, but do tool changes instead
[02:56:32] <zeeshan> it comes out perfect
[02:56:53] <zeeshan> i think i need to remeasure the vise jaws and see whats going on
[02:56:55] <zeeshan> maybe it is lifting
[02:57:12] <zeeshan> might sound weird but maybe its lifting at certain clamping locations
[02:57:40] <Duc> could be worn at those locations
[02:57:48] <zeeshan> yes
[02:58:35] <Duc> which country were you in again?
[02:58:40] <zeeshan> canada
[02:58:48] <Duc> does enco delivery there?
[02:58:51] <Nick001> indicator on the slid part of the bottom opening for the part would show that.
[02:59:07] <Nick001> solid
[02:59:17] <zeeshan> ill try that nick001
[02:59:24] <zeeshan> duc no idea :)
[02:59:48] <Duc> zeeshan: at times they have 25% codes which work on kurt vises
[03:02:16] <Nick001> To check the slides of side movement, you may need a 2' piece of a 2x4 to put a little pressure on it. Those slides look heavy enough to need it.
[03:04:56] <zeeshan> Nick001: thats a good idea
[03:05:02] <zeeshan> when i was inspecting the gibs
[03:05:07] <zeeshan> i should have done that

[03:05:37] <zeeshan> the table has a tendency to droop down
[03:05:42] <zeeshan> i was trying to lift at the front
[03:07:13] <Nick001> unusual vice - movable jaw is usually on the screw and solid jaw is where the movable jaw is now. Makes y axis programing easy - everything is in the plus direction.
[03:07:14] <Duc> how are you measuring the part deflecting?
[03:08:20] <zeeshan> Nick001: yea its backwards on this
[03:08:20] <zeeshan> :P
[03:08:38] <zeeshan> Duc: by checking the moveable jaw
[03:08:48] <Nick001> you may have to tighten that gib to reduce the drooping movement
[03:09:12] <zeeshan> i did
[03:09:20] <zeeshan> i got it down to 5 tenths
[03:10:36] <Nick001> That sounds good - wont move much by clamping - how about the upper ram
[03:11:21] <zeeshan> pretty damn straight!
[03:11:31] <zeeshan> i checked it again for droop
[03:11:32] <zeeshan> and side to side

[03:11:42] <Nick001> What is the vertical movement element?
[03:12:31] <zeeshan> you mean is it a ball screW?|
[03:12:51] <Nick001> I assume your using the fixed jaw for locating y axis on the part.
[03:13:02] <zeeshan> no i wasnt
[03:13:06] <zeeshan> thats one of the mistakes im making
[03:13:20] <zeeshan> i correctedf my cam program abit ago to deal with that
[03:13:26] <zeeshan> ill try it out tomorrow
[03:13:42] <Nick001> No - what is actually moving for vertical movement
[03:13:59] <zeeshan> the table

[03:16:01] <Duc> yea almost there for me Last game of basketball
[03:16:11] <Duc> wish my mill used the table for movement
[03:17:07] <Nick001> extend y axis to where the scraping marks are worn and check for side play and up and down play.

[03:17:34] <pink_vampire> the ph scale is not 0-14??
[03:17:49] <pink_vampire> what is -4 ph?
[03:18:15] <Nick001> 11pm is when solutions for the days problems get solved.
[03:19:36] <djdelorie> the normal pH scale is 0-14 for HCl and NaOH but pH is a measure of H+ ions which *could* (theoretically) exist in solution outside of the HCl/NaOH ranges
[03:20:39] <djdelorie> (at least, that's my guess)

[07:12:19] <pink_vampire> maybe it's come form the 2024

[14:09:59] <DaViruz> that spindle mount looks very flimsy
[14:10:25] <archivist> look at the accuracy they are claiming
[14:10:58] <DaViruz> i think they are confusing accuracy with naive resolution
[14:11:05] <cradek> haha, I was laughing already when I read it as .005 inches
[14:11:27] <DaViruz> i've bought some aluminum profiles from marchantdice
[14:11:46] <archivist> but for that price they could actually make something good
[14:12:40] <pink_vampire> I broke a nail
[14:12:51] <pink_vampire> !!!
[14:13:26] <archivist> cut the rest to match, then you can do some real work
[14:14:20] <cradek> mine are gnarly after some small filing work last weekend. I use them to hold stuff and always end up filing them weird.
[14:14:42] <DaViruz> i'm curious about those trunnions
[14:14:49] <pink_vampire> archivist: let me do some inspection before.
[14:14:52] <DaViruz> i wonder if they just contain a belt reduction
[14:15:16] <DaViruz> i also wonder what kind of bearings they use, and how they're mounted
[14:15:30] <pink_vampire> I'm thinking it's just a crack and the nail polish save the nail!
[14:15:42] <pink_vampire> YES!!
[14:15:54] <pink_vampire> it's save my nail!!!
[14:16:06] <pink_vampire> omg! that was close!!
[14:16:33] <pink_vampire> huge relief!!!!!!!
[14:17:10] <pink_vampire> I have to start doing some real nothing.
[14:19:21] <Loetmichel> Muhaha... co-worker just used a rivet tool to put some rivet nuts into an eclosure panel... M4 steel rivets... this tool:
http://www.cyrom.org/palbum/main.php?g2_itemId=16161 ... a few moments later i hear a big *KNACK* followed by hysterical laughter... no, the threaded bolt that pulls the rivets is still in one piece... the loer grip isnt... broken clear off the tool... seems to be scast
[14:19:21] <Loetmichel> steel instead of forged steel.. and the 60cm long aluiminium tubes had waaay to much leverage for that ;)
[14:25:49] <miss0r> Sync, I hav ethe solution now - I will try it later. What I completely missed in the guide is, I have to physically move a couple of wires in the controller to acomplish this.
[14:26:01] <pink_vampire> before and after pics please

[14:46:49] <Loetmichel> because you need the pin to turn freely and accessible from behind
[14:47:40] <pink_vampire> they look the same for me
[14:48:52] <Loetmichel> the pin on the back has to be turned to free the riveter from the rivet adter pressing it in
[14:49:15] <Loetmichel> so that doesent work with the usual ait actuated riveters because they have no channel to putthe pin thru

[16:56:47] <Encapsulation> its only been 9 days for me, I have years to catch up on
[16:56:50] <maxcnc> i showed you the parts to make your own one
[16:56:55] <Encapsulation> I have them in my ebay
[16:57:05] <Encapsulation> and bookmarked
[16:57:21] <maxcnc> behind me is a plasma parts less then 1k sold on 8k
[16:57:34] <maxcnc> thats why o got a real good drill
[16:57:58] <Encapsulation> time is money as well, I do need to consider
[16:58:04] <Encapsulation> I've basically decided on a machine now
[16:58:06] <maxcnc> you can make money out of people like you that dont like to drill a hole on there own
[16:58:07] <Encapsulation> its the raptor machine
[16:58:14] <maxcnc> spend money on parts you realy need
[16:58:21] <Encapsulation> well the gantry side plates
[16:58:25] <Encapsulation> not sure how I would do those myself
[16:58:30] <Encapsulation> or z plate etc
[16:59:02] <maxcnc> its just plate on plate
[16:59:27] <maxcnc> ok you decided
[16:59:43] <Encapsulation> raptor 12"x30"x4" 5" z clearance for $2500 or raptor 25"x30"x8" for $3800
[16:59:55] <Encapsulation> trying to decide now if I should spend the extra now so I dont regret a too small work area later
[17:00:06] <Encapsulation> even though the smaller would work, for now
[17:00:09] <Encapsulation> seems like the bigger I could do more
[17:00:14] <Encapsulation> I dont want to buy another machine in a year
[17:00:48] <Encapsulation> I think either way I could sell it and get 75%?
[17:00:52] <Encapsulation> if it didnt work out for me
[17:01:08] <Encapsulation> that wouldnt be ideal though, I'd like to make the right choice first time
[17:01:22] <maxcnc> dont agree the money is not to be spend
[17:01:23] <maxcnc> you will quick decide to go mutch higher on that
[17:01:32] <maxcnc> if your first alu plate work will show you the cramp to the mashie
[17:02:01] <Encapsulation> are you saying to get the bigger machine because I'll want the space later?
[17:02:28] <maxcnc> no
[17:02:34] <maxcnc> take the lower one
[17:03:31] <maxcnc> there are only 425oz on the mashine
[17:03:51] <maxcnc> i showed you wantei 1200oz at 350USD
[17:04:26] <maxcnc> so the extras on selfbuild woudt go to the bearing tread frame
[17:04:41] <maxcnc> not to the pocket of raptors
[17:05:43] <gregcnc> how does machine manufacturers convince machine shops to buy machines rather than building their own?
[17:05:51] <maxcnc> parts are local within 4days
[17:05:51] <maxcnc> mounting and soldering IF 8hr
[17:05:51] <maxcnc> on raptor you got to live with what you owned
[17:06:24] <maxcnc> on time limitation offen best to go
[17:06:24] <Encapsulation> hmm
[17:06:50] <maxcnc> greg somtimes more then 10parts a pice is best to go outsorcing
[17:07:03] <Encapsulation> I can see how I could build myself... except the side plates... I dont have anything to make those with
[17:07:06] <Encapsulation> gregcnc, because time is money as well
[17:07:22] <Encapsulation> I read self build is 1-6 months.... I read one person 2 years later, no cuts
[17:07:46] <djdelorie> buy a kit, put it together in a weekend. You could have been cutting by now.
[17:07:55] <Encapsulation> I can understand how I could build it myself... except these:

[17:27:00] <Encapsulation> 12" seems awfully small

[17:30:30] <Encapsulation> on the smaller one
[17:30:30] <djdelorie> perhaps you need a large-area-small-Z machine for sheets, and a small-area-big-Z machine for lumpy bits?
[17:31:08] <Encapsulation> thats not a bad idea
[17:31:10] <djdelorie> I mean, a 7x7x7 work area handles anything with a 7x7 cross section as long as the build plate doesn't move
[17:31:41] <Encapsulation> my largest enclosures are right around 10x10
[17:32:19] <djdelorie> so get a small solid machine for the work you *know* you need *now*, and take the time to make a larger DIY machine for the work you don't have yet.
[17:33:59] <Encapsulation> I almost just got a very small ebay machine like 3040 but for a decent looking one is ~600 and that seems like money wasted. for pcbs I really need .4mm precision

[17:35:22] <Encapsulation> I've always been a bit of a perfectionist although it hasnt served me that well

[17:35:57] <Encapsulation> because of the pcbs I need to cut

[17:36:45] <archivist> it is trivial to buy in PCBs
[17:37:09] * djdelorie uses UV exposure and chemical etch for pcbs...
[17:38:07] <Encapsulation> pcbs are secondary use for me, the primary is cutting beautiful enclosures for my products
[17:38:10] <archivist> I want my production bugs finding as well, you have to do it properly for that
[17:38:38] <swarfer> had a look at the openbuilds C-beam machine? openbuilds.com
[17:38:49] <Encapsulation> I looked at the ox
[17:38:53] <Encapsulation> let me see the C-Beam I think I saw it
[17:39:00] <swarfer> 12x12" router designed for cutting aluminum
[17:39:02] <djdelorie> you did, and the ox
[17:39:41] <djdelorie> heh, the purpose of the c-beam is to make the custom parts for the ox...
[17:40:12] <swarfer> but of course is not limited to that use (-:
[17:40:59] <djdelorie> the only "drawback" in this case is the moving build plate, so you can't work on part of a larger piece
[17:41:10] <swarfer> I would not recommend an ox for PCB cuttting, though I shall certainly try with mine when I eventually get it finished
[17:41:34] <archivist> a file, wet&dry, graver and hand work can get a good finish
[17:41:59] <swarfer> I have made PCB's on my drill press with an XY vice
[17:42:04] <swarfer> nasty
[17:42:32] <archivist> I etched and drilled one pcb in my lifetime
[17:42:59] <Encapsulation> about 1200 for c-beam all said and done
[17:43:53] <Encapsulation> https://en.wikipedia.org/wiki/Quad_Flat_Package
[17:43:58] <Encapsulation> this is the precision I require
[17:44:01] <Encapsulation> whichever machine I get
[17:44:06] <Encapsulation> upper right image
[17:44:17] <Encapsulation> well to be more specific
[17:44:18] <Encapsulation> .4mm pitch
[17:44:28] <PCW> unless you are in a huge hurry for second rate protos, milled PCBs are pretty worthless
[17:44:47] <Encapsulation> how so
[17:44:59] <archivist> not plated etc
[17:45:06] <Encapsulation> pcb same day, no cost after initial investment
[17:45:09] <archivist> no pth
[17:45:09] <PCW> no PTH no soldermask no inner planes
[17:45:16] <PCW> garbage
[17:45:24] <Encapsulation> I dont need those though
[17:45:45] <archivist> not like the real thing so may fail when you make a real one
[17:45:46] <Encapsulation> I just need to cut functional smd in very specialized shapes
[17:46:36] <swarfer> the only thing to watch for is getting the work mounted flat, absolutely critical at 0.4mm spacing
[17:47:04] <Encapsulation> I was going to try to setup one of those z height probe systems
[17:47:08] <Encapsulation> it probes the entire pcb ahead of time
[17:47:13] <Encapsulation> to correct for minor z height differences
[17:47:14] <PCW> for hand assembled protos if you do not value your time or the quality of the result, and need them right away and you are OK with 2 layers, maybe
[17:47:31] <PCW> still very low quality
[17:47:34] <swarfer> yep, that will do it quite well, but do the physical setup as well as you can before letting the softwar ehave a go
[17:47:53] <archivist> for production impossible to match a production pcb company
[17:48:23] <Encapsulation> https://www.google.com/search?q=cnc+pcb&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi_8taGh_jLAhWDFj4KHZw7DBIQ_AUICSgD&biw=1920&bih=1024#tbm=isch&q=cnc+pcb+smd&imgrc=Uu9OuXCSz4aiQM%3A
[17:48:24] <swarfer> Encapsulation said "special shapes"....
[17:48:26] <Encapsulation> I suppose that depends on the machine
[17:48:39] <Encapsulation> these results I'm seeing here the SMD ones look like they would be perfect
[17:48:54] <Encapsulation> I'm just not sure if the cheap ebay machines like 3040 are capable of such precision
[17:48:57] <djdelorie> most fabs do "special shapes" though
[17:49:10] -!- nofxx [nofxx!~nofxx@unaffiliated/nofxx] has joined #linuxcnc
[17:49:30] <Encapsulation> the price and MoQ seem high though
[17:49:37] <Encapsulation> when I start to think long term
[17:49:53] <archivist> not really you just need to go to the right place
[17:50:49] <PCW> If you only need 1 PCB per type and like hand soldering wires for VIAs maybe
[17:51:44] <archivist> PCW, I come from the time where we did that in production :)
[17:51:45] <Encapsulation> http://www.electro-tech-online.com/attachments/20090405-z8e-w5100-005-jpg.29947/
[17:51:49] <PCW> Great for throwaway protos or one-offs, not so great for anything thats a product
[17:51:51] <Encapsulation> thats all I need, that type of result
[17:52:03] <Encapsulation> depends on how you market the product
[17:52:05] <Encapsulation> and what the product is
[17:52:14] <Encapsulation> if its a handmade guitar pedal, you could actually charge more.
[17:52:16] <Encapsulation> imo
[17:52:24] <Encapsulation> by saying the pcb is made in house
[17:52:29] <Encapsulation> I would spin that as a feature
[17:52:32] <Encapsulation> of the product
[17:52:36] <Encapsulation> but thats just an example
[17:52:38] <Encapsulation> not my use case
[17:52:49] <PCW> you mean low quality is a feature?
[17:52:51] <archivist> they would expect the pcb to be plated and screened when they open the box
[17:52:54] <Encapsulation> its not low quality
[17:52:57] <Encapsulation> its just different
[17:52:59] <gregcnc> if its a hand made cnc machine you can charge more too?
[17:53:17] <Encapsulation> archivist, not if they look at the pictures ont he website
[17:53:28] <Encapsulation> I would be happy to see a custom cut pcb in a guitar pedal
[17:53:30] <PCW> Artisan PCBs
[17:53:32] <Encapsulation> happier than a chinese pocb
[17:53:33] <Encapsulation> for real
[17:53:40] <Encapsulation> you know you can charge 200 just if the pedal is made of wood
[17:53:44] <Encapsulation> even if it does nothing
[17:53:46] <Encapsulation> you instantglyu get moree
[17:53:52] <Encapsulation> so this is the type of thing I'm saying
[17:53:56] <archivist> I call that fraud
[17:54:03] <Encapsulation> I'm just saying
[17:54:07] <Encapsulation> in some markets
[17:54:10] <Encapsulation> people will pay for "artisan"
[17:54:18] <djdelorie> "lovingly hand-screwed-up with care"
[17:54:24] <Encapsulation> all I can say is
[17:54:27] <Encapsulation> I'd buy it before chinese
[17:54:56] <gregcnc> yet you're considering chinese routers
[17:54:57] <Encapsulation> and these pcbs I'm seeing dont look like juink to me
[17:55:36] <djdelorie> most hand-made PCBs I've made have turned to junk over the years, due to corrosion. Protecting them from oxidation and stuff is important.
[17:55:50] <djdelorie> the ones I want to last take extra steps
[17:55:51] <Encapsulation> http://www.kejiepcb.com/wp-content/uploads/2016/03/pcb4.jpg
[17:55:54] <Encapsulation> I need a little bit smaller even
[17:56:00] <Encapsulation> but that looks fantastic to me
[17:56:19] <archivist> it will corrode away in no time
[17:56:31] <Encapsulation> coat it
[17:56:37] <Encapsulation> spray it with some acrylic type coating
[17:56:38] <Encapsulation> to seal it
[17:56:40] <archivist> the plating and resist matter
[17:56:40] <Encapsulation> just an idea
[17:56:47] <djdelorie> I use a combination of chemical tin and polymer mask
[17:56:52] <Encapsulation> I'm going to have to call bs on that
[17:56:54] <Encapsulation> on it corroding away
[17:57:01] <Encapsulation> that sounds highly unlikely
[17:57:04] <djdelorie> but really, once you get the design right, have a batch made and never worry about it again
[17:57:11] <Encapsulation> I've seen some OLD pcbs that look a lot like that they arent corroded away
[17:57:14] <djdelorie> that is, professionally made
[17:57:25] <djdelorie> OLD pcbs are hot-tin-dipped
[17:57:26] <Encapsulation> if my volume was large enough that would make sense...
[17:57:36] <djdelorie> a batch of 10 is still cheap
[17:57:47] <archivist> before cad and cnc I did this
http://www.collection.archivist.info/archive/DJCPD/PD/2015/2015_07_12_tape_up_PCB_design/IMG_1940.JPG
[17:58:00] <gregcnc> if you're volume is low you just charge more for your artisan product
[17:58:04] <gregcnc> your
[17:59:07] <Encapsulation> it would still get me up and running for prototypes
[17:59:14] <Encapsulation> and allow me my main use which is to route 2-4mm enclosures
[17:59:22] <Encapsulation> regardless of how the pcbs come into existence I need the panels
[17:59:22] <Encapsulation> https://www.amphenolcanada.com/ProductSearch/drawings/AC/MUSBD111XX.pdf
[17:59:23] <Encapsulation> cuts like this
[17:59:27] <Encapsulation> as many as 10 per panel
[17:59:37] <Encapsulation> I have 10 poanels to cut for the first job
[17:59:45] <Encapsulation> with a dremel thats going to look like shit and take forever
[17:59:52] <Encapsulation> and I will also get cut
[18:00:01] <Encapsulation> so the primary u se will be routing the enclosures
[18:00:17] <Encapsulation> but the ability to cut custom "carrier" pcbs
[18:00:23] <Encapsulation> to solder headers on and plug multiple modules into
[18:00:25] <Encapsulation> to rapidly test ideas
[18:00:27] <Encapsulation> would be invaluable
[18:02:13] <gregcnc> running a business isn't easy
[18:02:30] <Encapsulation> http://3690-presscdn-0-3.pagely.netdna-cdn.com/wp-content/uploads/2012/07/P1310019.jpg
[18:02:32] <Encapsulation> I'm realizing this
[18:03:00] <Encapsulation> http://www.protocase.com/img/products/cnc/cnc-machined-enclosure-01.jpg this wouldnt be economical probably
[18:03:01] <gregcnc> if it's a hobby, throw as much money and/or time at it as you want
[18:03:34] <Encapsulation> http://www.8020cnc.com/images/alu_engrave1_large.jpg http://i.ebayimg.com/images/g/Pk0AAOSwHgVW77ne/s-l300.jpg
[18:04:37] <Encapsulation> http://www.8020cnc.com/images/alu_engrave1_large.jpg
[18:04:47] <Encapsulation> I wonder what it would cost to have something like that cut
[18:05:00] <gregcnc> If you qty is low, how long before you get a return on your investment in money and time compared to farming it out?
[18:05:07] <Encapsulation> my thinking is that between the wait times and the costs, it would add up to the cost of the machine in not too long, plus the convenience of having it at home
[18:05:23] <Encapsulation> gregcnc, thats a good point
[18:05:38] <Encapsulation> I would have to accept that part of the money would be going to convenience factor, and self-sufficent factor
[18:05:48] <Encapsulation> and would be difficult to pay back as quickly as farming out on a small scale
[18:05:51] <gregcnc> either way errors or design changes cost time or money
[18:06:03] <Encapsulation> thats true

https://www.youtube.com/user/submarineboat
[18:37:31] <Loetmichel> building a 60 ton steel boat.... 1000 miles from the next ocean... all alone + internet ;)
[18:38:42] <Loetmichel> i omitted a few nights sleep to see all 153 videos in a binge. ;)
[18:40:00] <Loetmichel> great attidtude tho. "oh, we dont have the money to buy a propeller for the ship? lets just learn how to do a decent brass foundry job ourselves ;)
[18:43:58] <djdelorie> my dad was a chief engineer on a tugboat. When they needed to work on the engine, they - literally - sliced the top half of the boat off and set it aside, and welded it back on later.

[18:55:53] <Loetmichel> djdelorie: nice
[18:56:54] <Loetmichel> i would have thought they use compressed air to start?
[18:57:10] <Loetmichel> all big ship diesels i know do it that way
[18:57:13] <djdelorie> one V8 powers a generator for electricity, the other runs the air compressor
[18:57:18] <Loetmichel> ah
[18:57:24] <Loetmichel> so i was not wrong ;)
[18:57:36] <djdelorie> but yes, synchronized compressed air drives the cylinders to get it turning. Ear protection is required.
[18:58:46] <Loetmichel> the 70m Sub hunter i did my mandatory service on had 2 12 meters long 3500hp 16cyl V engines with a max RPM of 3000...
[18:59:09] <Loetmichel> ... and 4 110kW gensets
[19:00:04] <Loetmichel> and a small 100hp air compressor for the two BIG (~300 liters) "scuba tanks" that stored the 60 bar air to start the main engines ;)

[19:19:45] <unfy> they do flex a bit more than i had thought ... and i'm just using some 5/16 all thread... that isn't held perfectly captive on what it's riding on. soooo the entire lead screw can move back and forth a bit along it's axis.

[19:44:35] <SpeedEvil> I've wondered about little magnetic or similar thingies that support
[19:44:47] <SpeedEvil> and pop out of the way when the nut comes along
[19:45:20] <unfy> depending on design, would some extra bearings in the moving part also help / add some stability....
[19:45:44] <unfy> so: bearing - some distance - nut - some dustance - bearing
[19:47:36] <evil_ren> speedevil: to hold up a sagging screw?
[19:48:39] <evil_ren> you could maybe mount them to the bottom side of the table so they mostly stay between the nut and the ends

[20:27:26] <unfy> coworker had a suggestion on the springy motor coupler vs non-captive lead screw --- put some hot glue in some of the coupler grooves to take out a bit of the play etc. worth a shot as a simple thing to make it just a bit better
[20:35:02] <malcom2073> unfy: I have a 1.5 meter linear actuator which has a sliding bearing support for theballscrew to prevent whipping
[20:35:46] <malcom2073> Basically it has two plastic bushings that have thin steel cable linking them to the carraige. When teh carriage moves, it pulls them along the ballscrew, and support the ballscrew in its tube further down from the nut
[20:36:13] <malcom2073> And since they're on cables, it doesn't reduce the throw of the actuator but by the thickness of both bushings

[20:40:02] <TurBoss> is Joint_axes what i need for an Y axis with 2 motor? the 2 motorha have to run in sync
[20:47:16] <Valen> djdelorie: look at rotating the nuts rather than the screw
[20:47:49] <djdelorie> but then you have *more* rotating things you need to stabilize...
[20:48:14] <Valen> you don't get jump rope though
[20:48:27] <djdelorie> no you get cat's cradle instead :-P

[22:56:58] <malcom2073> So... what temperature are varidrive pulleys supposed to get up to before I should worry?
[22:57:48] <malcom2073> vari-speed rather
[22:58:24] <SpeedEvil> Are those the ones with two conical faces and adjustable space between?
[22:58:42] <malcom2073> yeah
[22:58:55] <malcom2073> And the speed knobs
[22:58:57] <malcom2073> on the front
[22:58:58] <SpeedEvil> hmm
[22:59:03] <malcom2073> Mine is at 70c
[22:59:11] <SpeedEvil> My guess would be that would be fine
[22:59:18] <SpeedEvil> the belt does not contact the pulley for long
[22:59:39] <malcom2073> The drive is near silent when cold, but as it heats up, it gets louder and louder heh
[23:00:19] <malcom2073> Well it's in contact with the pully about 25% of the time or so heh
[23:00:20] <SpeedEvil> the belt will loosen as it gets warm - is there an idler in there?
[23:00:25] <malcom2073> There is not
[23:00:48] <SpeedEvil> Some nice silicone spray will help with reducing the friction :)
[23:00:57] <SpeedEvil> I have no sensible suggestion.
[23:01:11] <SpeedEvil> I have one of those pulleys from my washing machine that I decommissioned
[23:01:26] <malcom2073> This is thespindle on my mill heh
[23:03:36] <SpeedEvil> I am making a new 4 axis machine.
[23:03:41] <SpeedEvil> Though it is a quadcopter :)
[23:04:42] <malcom2073> heh

[23:41:22] <malcom2073> ssi: I'd have made more money this year had I worked the hours I worked, at a w2 job for the same wage
[23:41:48] <malcom2073> And being as I work two jobs, one w2 and one 1099... im thinking the one is getting dropped heh
[23:45:19] <enleth> malcom2073: supposedly it is normal for the whole varispeed body to get pretty hot to the touch
[23:45:36] <enleth> malcom2073: what mill model?
[23:45:44] <malcom2073> enleth: The pulley got up to about 70c and stayed there, that was the hottest part
[23:45:47] <malcom2073> it's a clausing kondia mill
[23:46:03] <enleth> malcom2073: sounds OK if it stabilizes at that temperature
[23:46:38] <enleth> malcom2073: is this one of the part-compatilbe birdgeport head clones?
[23:46:42] <malcom2073> Yeah, it goes from being quiet enough to talk in a normal tone to someone else, or listen to the radio, up to being loud enough it's hard to think once it warms up
[23:46:46] <malcom2073> enleth: No
[23:48:55] <enleth> malcom2073: are you able to take off part of the covering to see at least one of the pulleys during operation?
[23:49:11] <malcom2073> enleth: Yep, I'm actually running with the covers off
[23:49:26] <malcom2073> The covers are flimsy plastic grills, and they broke when I moved the mill (the strap hit them)
[23:49:28] <enleth> like, completely exposed?
[23:49:39] -!- basiclaser has quit [Quit: Connection closed for inactivity]
[23:50:12] <malcom2073> Not completly, the cover exposes a is a small rectangular hole that you can see the pulleys through
[23:50:24] <enleth> ah, OK
[23:50:42] <enleth> on a bridgeport, the top cover is an attachment point for the regulator plate, I suppose it's similar there
[23:50:42] <malcom2073> That's how I was measuring temp, through that with an IR thermometer
[23:50:54] <enleth> anyway, do you see any wobble when warmed up?
[23:51:23] <malcom2073> enleth:
http://media.liveauctiongroup.net/i/24032/21912125_3.jpg?v=8D24B13E9817AE0
[23:51:26] <malcom2073> Nope, no wobble
[23:51:43] <malcom2073> I have a different head, but the varibox is the same
[23:51:55] <malcom2073> Or at least, very similar to that
[23:54:05] -!- skunkworks has quit [Ping timeout: 248 seconds]
[23:55:29] <enleth> that's a pretty wide belt in there
[23:55:45] <malcom2073> it's about an inch on the outside iirc
[23:56:04] <enleth> anyway, other than trying some lubrication, there's probably nothing you can do about the noise
[23:56:42] <enleth> short of replacing the belt with a modern one made of better materials, maybe
[23:56:54] <enleth> if you have a vintage specimen
[23:56:59] <malcom2073> Maybe, I'll bet the belt is origional, 20 years old
[23:57:14] <malcom2073> I've heard replacing the belt is hell though heh
[23:58:19] <enleth> they do exist
[23:58:49] <enleth> at least for bridgeports you can still buy a proper belt, new, made of modern materials and all
