[02:55:48] <Deejay> moin
[03:50:19] <Hydrar> I don't remember if I asked here, but has anyone got any experience with Inventor HSM for CAM?
[03:52:14] <archivist> it has been mentioned in here ask a better question
[03:53:41] <Hydrar> Back from vacation and still frustrated why my double sided part ends up offset by a repeatable few mm, I can't manage to get it to drop steps no matter how hard I try
[03:55:00] <Hydrar> I can calibrate it out by offsetting the stock on the opposite side setup, but it feels like it's not the right solution
[03:55:11] <archivist> I think there are more users later on during american waking hours
[03:57:55] <Hydrar> Yeah, makes sense, I'll try to stick around as long as I don't need to reboot to windows, but not planning on doing any CAD at the moment
[05:23:36] <XXCoder> heys
[05:41:53] <enleth> eh, still waiting for the new ORAC VFD
[05:42:54] <enleth> right now, with the training cassette player and speakers, it's only good as a rave party tape deck but it's too heavy to comfortably take to a rave party
[05:43:25] <enleth> OTOH if I managed to do it, it would be one hell of a rave party
[05:45:37] <enleth> (the player distorts the sound so badly that only rave party music sound good on it; actually it sound better)
[05:49:07] <XXCoder> lol
[05:51:09] <jthornton> morning
[05:51:10] <_methods> Hydrar: what you're doing is completely normal
[05:51:16] <_methods> that's the whole point of work offsets
[05:56:28] <XXCoder> http://www.geologyin.com/2016/06/scientists-have-discovered-new-state-of.html interesting
[05:56:43] <XXCoder> new state of matter. may lead to high temperate superconductors
[05:58:27] <XXCoder> first person to invent room temperate superconductors will get all the money
[05:58:46] <XXCoder> well not literally but bill gates would be poor compared to that guy
[06:00:18] <Sync> nope
[06:02:22] <XXCoder> Sync: nope to what?
[06:05:54] <Sync> that they would be rich
[06:06:06] <XXCoder> ah dunno
[06:06:15] <XXCoder> sometims product just dont happen
[06:06:28] <XXCoder> like every and every one of those billion battery improvements
[06:07:06] <XXCoder> I don't remember how many times I read "omg lathinium ion with X improves battery life 10x"
[06:07:21] <_methods> https://en.wikipedia.org/wiki/Niels_Christensen
[06:07:27] <_methods> invented the o-ring
[06:07:27] <XXCoder> but if all worked together we'd be able to drive cars 1,000 miles with phone battery sized batteries
[06:07:30] <_methods> got paid shit
[06:07:50] <_methods> probably one of the most important inventions in 100's of years
[06:07:59] <XXCoder> "The Christensen air brake was successfully tested on Detroit's streetcar system, but a downturn of the economy prevented Christensen from manufacturing and marketing the system."
[06:08:05] <XXCoder> its little things.
[06:08:26] <enleth> XXCoder: presumably they'd have invented it in a team, using a lot of expensive equipment paid for by their employer, which means that unless they own substantial shares of said employer, or the employer is run by geeks and scientists instead of suits, the actual inventors are going to have a problem making a lot of hard cash on the invention
[06:08:30] <_methods> you can invent the most useful thing in the world, it doesn't mean you'll be compensated for it
[06:08:44] <XXCoder> indeed method
[06:09:04] <XXCoder> enleth: yeah room temperate superductor is too hard to be done by one person at home
[06:09:09] <XXCoder> likely anyway
[06:09:14] <enleth> XXCoder: the only option would be to convince the whole team to keep the ivention secret from the employer and bail out to form a new company, but even that is open to lawsuits
[06:09:24] <XXCoder> would be cracking funny if someone found a way using kitchen chemicals.
[06:17:16] <XXCoder> heh I remember this show where future criminals gets sent back in time to escape
[06:17:27] <XXCoder> one cop is sent back so he can send em forward
[06:17:40] <XXCoder> one set of criminals is stunned that there is bleach everywhere
[06:17:51] <XXCoder> they bought in weapons that use em
[06:18:08] <XXCoder> I wonder if there will be something equally common and very illegal future.
[06:21:22] <_methods> have you been using kitchen chemicals?
[06:21:31] <XXCoder> lol
[06:33:33] <enleth> XXCoder: encryption, I guess
[06:33:41] <Hydrar> _methods: I just thought if I position the zero of both sides setups identically, except inverting the axis that I turn the part over across, it'd be perfectly aligned, since I'm using a 4-pin fixture to keep the workpiece identically positioned
[06:35:00] <archivist> Hydrar, are the pins offset from 0
[06:36:19] <Jymmm> XXCoder: Luther, Season 2, Episode 3 (BBC)
[06:36:25] <Hydrar> arauchfuss: Yeah, the 0 is set on the bottom left edge of the fixture, which is also the corner of the workpiece
[06:37:25] <Hydrar> I actually have no formal education in this, I just ended up with a small CNC mini mill and trying to figure it out on my own
[06:38:00] <Jymmm> XXCoder: Not sure if this has CC or not http://putlocker.is/watch-luther-tvshow-season-2-episode-3-online-free-putlocker.html
[06:39:19] <archivist> Hydrar, we have no picture, we dont know if your pins are offset from your jig / item 0
[06:39:34] <Hydrar> archivist: pins are 5mm in from the edges, iirc
[06:40:09] <archivist> I imaging that is partly where your offset is
[06:40:15] <archivist> imagine
[06:40:26] <Hydrar> I have a feeling I'm just derping
[06:41:01] <Jymmm> XXCoder: Not really needed, just watch from 3:00m to 4:00m
[06:47:06] <Hydrar> archivist: Just gonna head home from work, took a picture of the machine, I'll be back in half an hour in case you're interested in helping me figure it ut
[06:52:36] <lauri> Hi guys, I just got Mach3 breakout board such as this: https://www.amazon.de/Breakout-Stepper-Driver-Controller-Project/dp/B00HV4Z4QI/
[06:53:07] <lauri> Could anyone suggest what should I pick in the LinuxCNC welcome menu to actually use it?
[06:54:54] <jthornton> use the Stepconf Wizard to create a parallel port configuration
[06:55:10] <Tom_itx> morning jt
[06:55:20] <lauri> jthornton: isn't there anything that works out of the box already?
[06:56:06] <Tom_itx> you're gonna need to configure it to your needs
[06:56:23] <Tom_itx> it's not that difficult
[06:56:29] <jthornton> paraport stepper pick one
[06:57:19] <jthornton> Tom_itx: the tool worked or at least said it did lol
[06:57:21] <jthornton> thanks
[06:57:42] <Tom_itx> np, i haven't noticed any ill effects from it yet either
[06:58:35] <Tom_itx> it probably just removes a couple registery entries
[06:58:54] <Tom_itx> i didn't much feel like hunting them down
[06:59:23] <jthornton> yea that sounds about right
[07:07:46] <jthornton> well the hoe is not broken (I think) so off I go to play in the dirt
[07:11:15] <jdh> not yet anyway
[07:11:22] <_methods> bout damn time you got that hoe back out there makin some money
[07:12:57] <archivist> I think he was deprived of a sandpit as a kid
[07:15:48] <lair82> Or he just never grew up, kinda like me.
[07:20:00] <lauri> thanks guys, got it working :)
[08:22:23] <Hydrar> archivist: Can I PM you a link to the pics of the setup?
[08:24:36] <_methods> if you're using dowel pins to locate the part you need to set your coordinate system off of them
[08:24:39] <_methods> not the edge of the part
[08:26:04] <Hydrar> _methods: Oh, right, cause I'm using the outer edge of the fixture right onw
[08:27:15] <Hydrar> _methods: https://cloud.hydrar.se/owncloud/s/vsgIjtbRMeJ68eC This is how it looks, centered the endmill on bottom left corner, raised it by the material thickness and zeroed
[08:27:25] <Hydrar> So I should do it on the pin rather?
[08:27:38] <_methods> one sec looking at your pic
[08:28:07] <Polymorphism> website no good
[08:28:29] <_methods> do you have a pic of your part on the locator pins
[08:29:10] <Hydrar> Nope, only in the CAD program, but it is centered, with the same size as the bottom plate
[08:29:32] <Hydrar> And yeah need to buy a SSL cert...
[08:30:01] <Sync> "need"
[08:30:05] <_methods> well if i'm using locator pins on a fixture then i use them as the zero, assuming that is the design intent
[08:31:17] <Hydrar> Well, intent is just to route parts out of a sheet mounted on the pins
[08:31:25] <Hydrar> So it can easily be flipped to route other side and cut them out
[08:31:30] <Hydrar> But brb a sec
[08:32:42] <_methods> well if the part you're routing isn't zero'd off of those pins or the center of your stock/part, then when you flip it you'll be off
[08:33:17] <_methods> but those pins seem extremely long
[08:34:10] <_methods> but i have no idea what you're doing, so my observation could be completely off
[08:37:41] <_methods> https://www.carrlane.com/catalog/index.cfm/29625071F0B221118070C1C513906103E0B05543B0B012009083C3B2853514059482013180B041D1E173C3B2853524B5B5E
[08:37:49] <_methods> i'd take a look at that if you're new to this
[08:38:04] <_methods> very basic fixture design concepts
[08:39:18] <_methods> but 3/4 of the time fixture failures are caused by overlooking these basic principles
[08:39:59] * alex4nder takes notes
[08:41:26] <archivist> pfft "notes", just bookmark/download that page
[08:41:53] <alex4nder> what am I? made of disk space?
[08:42:01] <_methods> haha
[08:42:08] <_methods> carr lane is a great fixturing resource
[08:42:19] <_methods> and they have models of all their stuf
[08:42:37] <_methods> makes it easy to design fixture then order
[08:43:41] <_methods> http://us.misumi-ec.com/maker/misumi/mech/tech/locatingpinshowtheyareused/
[08:44:04] <_methods> another good locator pin use page
[08:54:10] <_methods> https://letsencrypt.org/
[08:54:17] <_methods> free ssl
[08:55:40] <_methods> i think cloudflare does free ssl cert too
[09:04:03] <Hydrar> _methods: Thanks, that's exactly what I needed, and yeah need to check out letsencrypt sometime
[09:04:24] <Hydrar> But yeah I did try centering on a single part in the exact center of the sheet and it did work, so it makes sense
[09:04:40] <archivist> no real need for all this https stuff on plain websites
[09:04:55] <Hydrar> It's needed because owncloud sends passwords in cookies
[09:05:02] <Hydrar> And also the filesync proto
[09:11:25] <Hydrar> If this works well I'm actually considering converting this machine to linuxcnc
[09:12:01] <Hydrar> Hardware wise it seems pretty solid, just nccad7 is not very intuitive to work with
[09:13:28] <Polymorphism> what machine do you use
[09:16:46] <Deejay> re
[09:21:58] <Polymorphism> * Hydrar has quit (Remote host closed the connection)
[09:23:25] <Hydrar> Polymorphism: Max-computer KOSY2
[09:23:35] <Hydrar> A5 sized entry model
[09:24:13] <Polymorphism> ah nice, havent seen those
[09:26:11] <KreAa> cute
[09:30:33] <Hydrar> Polymorphism: It looks slightly better than some of the chinese machines I've seen in accuracy, but I really dislike the universal motor not keeping constant RPM and being unable to control RPM from gcode
[09:31:08] <Polymorphism> the rpm is variable?
[09:31:12] <Polymorphism> do you mean from load
[09:31:16] <Polymorphism> or just when free spinning
[09:32:06] <Hydrar> Polymorphism: During load, yeah
[09:32:29] <Hydrar> The metabo router does some sort of electronic regulation, but it doesn't seem to work very well at low RPMs
[09:32:49] <Hydrar> I do have a spare kress 1050FME laying around though that I've been planning to upgrade it to as soon as I get it running correctly
[09:34:05] <Polymorphism> sounds like a nice upgrade
[09:34:33] <Hydrar> It's still way overkill, considering the stuff I'm tasked with doing seems to be mainly 0.8mm endmills :P
[09:35:04] <Polymorphism> .8mm??
[09:35:07] <Polymorphism> what are you doing?
[09:35:21] <Polymorphism> I thought 1/8" was small
[09:35:21] <Hydrar> Model train parts
[09:35:36] <Hydrar> Was considering getting a .4mm too to try, but I have a feeling I'll wreck it
[09:35:37] <Polymorphism> can I see an example?
[09:35:54] <Polymorphism> the .4mm bit that came with my 3d printer looks like it would break if you touched it wrong xD
[09:36:53] <Hydrar> I don't have any pics handy, but it's the connecting rods between the wheels of a swedish locomotive
[09:37:08] <Hydrar> Seems overall faster to mill compared to 3d print + cast + cleanup
[09:37:36] <archivist> file!
[09:38:04] <Hydrar> File, what's that? That's what we have cnc for :P
[09:39:00] <archivist> I make the tools small rather than the loco
[09:39:27] <archivist> mostly hand work
[09:39:43] <Hydrar> Ah
[09:39:49] <archivist> http://www.collection.archivist.info/archive/DJCPD/PD/2004/2004_05_08_7mm_loco/P1010109.JPG
[09:40:36] <Hydrar> archivist: Damn that's tiny, that's smaller than H0 scale right
[09:40:59] <Hydrar> (I actually know almost nothing about model trains, I just somehow managed to end up working with them)
[09:41:16] <archivist> that was a repair job
[09:42:08] <Hydrar> Ah
[09:42:24] <Hydrar> Cute tools though, you need pliers to use them? :P
[09:42:34] <archivist> also when making small parts a home made cutter can often be used
[09:42:58] <Polymorphism> Hydrar, is this for a customer?
[09:43:32] <Hydrar> Polymorphism: I'm prototyping production parts essentially
[09:43:38] <Hydrar> For the company I work at
[09:43:53] <Polymorphism> ah nice
[09:44:12] <Hydrar> But I do lots of things, the CNC was just a recent thing that appeared, had been collecting dust for a few years
[09:44:53] <archivist> Hydrar, need small gears? http://gears.archivist.info/gears/IMG_1214_hires.JPG
[09:45:00] <Polymorphism> I can't imagine a working cnc collecitng dust @_@
[09:45:24] <Polymorphism> archivist, how did you make those
[09:45:32] <Polymorphism> is that brass?
[09:45:33] <Hydrar> I don't know either, I even use it for drilling just with manual gcode now, takes all the guesswork out of using a drill press
[09:45:52] <Hydrar> Damn that's tiny
[09:46:15] <Hydrar> I haven't actually seen much of that small scale, everything seems to be H0 at work which is a size above, but still pretty tiny
[09:46:39] <archivist> Polymorphism, on the end of a stick in the rotary on the 5 axis
[09:48:50] <Polymorphism> archivist, http://www.ebay.com/itm/CNC-Engraver-Machine-H-Style-Rotary-Table-A-Axis-B-Axis-4th-5th-Rotational-Axis-/ would this be a nice upgrade for my machine? or is it junk. Or should I probably be focusing in 3 axis first
[09:49:04] <Sync> both of the latter
[09:49:21] <archivist> that is junk
[09:49:24] <Sync> you want one with a harmonic drive
[09:50:08] <archivist> real vertex rotary is ok, cheap tooling, morse collets
[09:52:05] <Sync> I like my lehmann rotary
[09:53:52] * Polymorphism googles
[09:53:59] <archivist> basic setup for working on the end of a bar http://www.collection.archivist.info/archive/DJCPD/PD/2009/2009_08_15_Watch_verge_escape_cnc/IMG_0276.JPG
[09:56:11] <archivist> and a close up of the contrate gear being cut http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_03_31_contrate_gear_prototype/IMG_1205.JPG
[09:57:20] <Polymorphism> nice
[09:57:28] <Polymorphism> "basic" setup =P
[09:57:36] <archivist> http://www.collection.archivist.info/searchv13.php?searchstr=contrate+pd
[09:58:19] <archivist> it took a while to get good pictures
[09:58:48] <Polymorphism> what is the gear cutting tool called?
[09:58:52] <Polymorphism> the endmill
[09:59:02] <archivist> that is not an endmill
[09:59:17] <Polymorphism> I see
[09:59:21] <Polymorphism> what is it?
[10:00:14] <archivist> that is a random watch wheel "gear milling cutter" that looked close enough for the job
[10:09:54] <Polymorphism> $80 for a new ballscreww + nut
[10:09:54] <Polymorphism> wtf
[10:09:59] <Polymorphism> $60 of which is shipping, apparently.
[10:10:05] <Polymorphism> wtfever, no choice at this point
[10:10:18] <Polymorphism> Can't have that cash sunk into a pile of useless parts
[10:10:23] <Polymorphism> it must be completed.
[10:11:49] <Sync> just get it repacked finally
[10:12:15] <Polymorphism> I can't
[10:12:20] <Polymorphism> I have to value my time at something
[10:12:24] <Polymorphism> I put 4 hours into it
[10:13:21] <Polymorphism> I even drilled out a dowel and attached it to a drill to sand it down to 16mm
[10:13:28] <Polymorphism> then tried to use it to hold the balls in place
[10:13:38] <Polymorphism> but it didnt seem to be able to be in there while at the same time screwing the nut back on
[10:13:43] <Polymorphism> I may give it one more try
[10:13:52] <Polymorphism> not sure if the replacement has shipped out or not yet
[10:15:18] <Sync> well, even if you put 4h into it, you clearly don't value your time much because it cost you a lot of downtime
[10:16:05] <Polymorphism> I thought it would just go back together
[10:16:08] <Polymorphism> it's all downtime right now
[10:16:21] <Polymorphism> I'm not sure it can count as downtime though when it hasn't been up yet
[10:19:46] <Sync> it just goes back together
[10:20:49] <archivist> must not plug that bit of test gear in till repaired, knocked my earthfault out :)
[10:21:03] <Polymorphism> Sync, it would jam up every time right near the end
[10:21:14] <Polymorphism> Now I can't even get it back apart.... I took both wipers off but it won't budge
[10:21:29] <Sync> take the plugs out
[10:21:35] <Polymorphism> they go out through the inside
[10:21:40] <Polymorphism> you cant taske them out from outside =\
[10:21:44] <archivist> bit of grit, try harder
[10:21:58] <Polymorphism> I'll take another look this evening
[10:25:07] <newcnc22> Hi, can somebody please tell maxcnc he shall connect me. He's the only one to help me with my problem. I have updated to 2.8 and since then nothing is working. I have overwritten my INI file and else, so that It has to be written all again.Thx
[10:25:53] <Polymorphism> lol
[10:25:57] <Polymorphism> I'll let him know
[10:26:06] <newcnc22> Thx
[10:26:08] <Polymorphism> np
[10:26:22] <newcnc22> Nice
[10:30:01] <Sync> I could pry the ones my screw had out Polymorphism
[10:31:17] <Polymorphism> http://g03.a.alicdn.com/kf/HTB1MhvYKpXXXXccXpXXq6xXFXXX1/TBI-1605-C3-300mm-ballscrew-with-SFU1605-ball-nut-end-machined-for-BK12-BF12-high-precision.jpg
[10:31:20] <Polymorphism> it looks like that Sync
[10:31:27] <Polymorphism> they are wider underneath so they won't come out that way
[10:31:53] <Polymorphism> I can't find a picture of the plastic piece
[10:33:42] <Sync> then press them out, load the nut part way and then press them back in
[10:36:17] <Sync> but usually you don't need to
[10:51:19] <roycroft> my braking resistor is awaiting me at the post office
[11:07:22] <CaptHindsight> is 6D even stronger than 5D? http://www.3ders.org/articles/20160623-mitsubishis-5d-printed-parts-3-5x-stronger-than-3d-printed-counterparts.html
[11:08:17] <plpower> cool cnc lers are there arcooled 1,5KW spindles out with VFD for a cncn small mashine
[11:18:35] <Polymorphism> interesting link CaptHindsight
[11:20:35] <CaptHindsight> plpower: like this? http://www.ebay.com/itm/65MM-1-5KW-ER11-FOUR-BEARING-AIR-COOLED-MOTOR-SPINDLE-AND-INVERTER-DRIVE-VFD-CNC-/281329841813
[11:21:32] <plpower> Thanks i fonbd and orderd one shipment within germany
[11:21:45] <plpower> oh my english is real bad
[11:22:01] <CaptHindsight> better than my German
[11:22:07] <plpower> 220Euros all in cluded
[11:22:22] <plpower> thanks for the help
[11:22:26] <Polymorphism> watcfh ytour collet
[11:22:30] <Polymorphism> thas only er11
[11:22:37] <plpower> i got so many cnc orders i bearly can build that fast
[11:22:44] <Polymorphism> congrats plpower
[11:23:11] <CaptHindsight> plpower: machines for you or are you selling machines?
[11:27:05] <plpower> im making for schools internal sellings no offer to outsiders
[11:27:36] <plpower> folks are There adapters for ER25 on ER11
[11:31:18] <Polymorphism> I don't think you can go bigger, that doesn't make sense
[11:31:31] <Polymorphism> but, I have no idea really.
[11:49:12] <Hydrar> Is there any toolchanger VFD spindles for less than 1500€?
[11:49:31] <Hydrar> Sorotec has a water cooled 2.2kW mechatron spindle that looks awesome
[11:49:41] <Hydrar> But it's like... kinda out of all the budgets and then some
[11:50:53] <plpower> make your own with simple fast quick adapters for
[11:50:58] <plpower> er20
[11:51:43] <plpower> ok im off i orderd a collet adapter for er20 on er11
[11:51:55] <plpower> hope it will fit wood chipping
[11:58:19] <Polymorphism> plpower.... no
[11:58:58] <Sync> Hydrar: the chinese bt30 spindles with drawbars come in at I think 900 or so
[12:08:32] <Hydrar> I've noticed any VFD spindle below 2.2kW does not seem to state it supports cutting steel, does cutting even with small tools really need 2.2kW or is there some other design changes with how it's built?
[12:08:57] <Hydrar> I thought machine rigidity was a way bigger issue than spindle power anyway, as long as you are >1kW
[12:09:31] <Sync> I don't see any reason why you could not cut steel with a smaller spindle
[12:09:45] <Sync> you are just limited to relatively small tools
[12:13:24] <Sync> something like 3mm tools or something like that so that you can get the spindle speed up
[12:18:47] <Loetmichel> MAN i must have done something wrong in a previous life. My car broke down again at the grocery store... seems it gets no fuel into the injectors... Why me every time???
[12:19:35] <roycroft> i'm having injector problems myself
[12:19:49] <roycroft> unfortunately the solution was $600 to replace the "master" injector
[12:19:52] <roycroft> which i've done
[12:20:01] <roycroft> and now another $600 to get the other three injectors rebuilt
[12:20:49] <roycroft> at 217,000 miles i guess i shouldn't complain
[12:21:33] <roycroft> and i'm already getting more power and better fuel economy having only replaced the one injector
[12:25:44] <Loetmichel> roycroft: i just paid 3900 eur for a engine overhaul and had the car at the workshop for 4 months... just got it back the third week... now this. i am a bit pissed now...
[12:39:01] <roycroft> i can understand that
[12:39:33] <roycroft> i have just developed a fuel leak
[12:39:43] <roycroft> my mechanic is going to look at it tomorrow
[12:39:56] <roycroft> but this happened right after i got it back from having that injector replaced and the fuel filter replaced
[12:40:23] <roycroft> i'm hoping it's something simple, such as a hose that cracked or didn't get attached properly when he did the work
[12:40:29] <roycroft> or maybe a bad injector seal
[12:40:45] <roycroft> but it's really frustrating to get work done on a vehicle and then have it continue to be broken
[12:41:48] <remy_> Bonjour, je cherche quelqu'un pour m'aider a installer linuxcnc sur mon ubuntu qui est déja installé.
[12:42:52] <Loetmichel> roycroft: tell me about it. i got the Opel back with 40kmh less top speed and 2 liters more per 100km in consumption. They damaged the torque converter while "repairing" the Engine.
[12:43:21] <Loetmichel> and dont take any responsibility. "we dont have dismantled the transmissin, thats not our fault!"
[12:45:01] <Sync> well, they have to have fiddled with the TQ converter to change the rear main seal
[12:46:25] <Loetmichel> Sync: well. i have not enough monet to sue. so they get away with it.
[12:46:55] <Loetmichel> and now i have to see how to get the car to a different mechanic. preferably one that knows his trade a bit better
[12:47:04] <Loetmichel> money
[12:47:09] <Tom_itx> Loetmichel get a bicycle
[12:48:50] <Tom_itx> don't look for one standing under a shade tree
[12:48:51] <Loetmichel> Tom_itx: atm i am back to driving the BMW 316ti beater i still had sitting around. its MOT is overdue, but for at least a month the fine for tat is only 15 eur. so if i am fast with reparing the Omega i still can sell it afterwards ;)
[12:49:37] <Tom_itx> there are fewer and fewer ppl i trust with any type of repair nowdays
[12:50:03] <Loetmichel> s/mot/TUEV (bi-annual state inspection of cars in germany)
[12:50:25] <Loetmichel> Tom_itx: same here. for good reason
[12:50:37] <Tom_itx> yup
[12:51:52] <Tom_itx> i thought german mechanic was a coveted position there
[12:53:04] <Loetmichel> Tom_itx: like a friend of mine said once: "there has to be a place where all the mechanics which graduated with 4- have to find a job..."
[12:53:20] <Loetmichel> 4- in germany is about D- in america i guess
[12:53:30] <Tom_itx> in your neighborhood?
[12:53:51] <Loetmichel> i think i know 2 car workshops now where they work ;)
[12:53:53] <Tom_itx> they should be required to do it over
[12:54:04] <Sync> well, they are
[12:54:18] <Sync> but it is a lengthy process to actually get them to do it
[12:55:04] <Tom_itx> i certainly know a dealership i don't trust and you would think of all places the dealer would be one

[13:50:14] <CaptHindsight> kanzure: weren't these much more expensive only last year? http://www.glenresearch.com/Catalog/catalog.php?page=abi
[14:01:08] <kanzure> hi
[14:01:17] <kanzure> good question
[14:01:22] <kanzure> btw i still want to fund this sort of project
[14:01:28] <kanzure> also, the human genome project is interested in this project
[14:02:21] <CaptHindsight> kanzure: heh, our own guberment is interested
[14:02:38] <kanzure> human genome project, i nthis case, is organized by a friend of mine
[14:02:54] <kanzure> i am traveling to visit them on sunday or monday (i am presently in boston for a w3c thing about bitcoin and blockchain)
[14:03:07] <CaptHindsight> NIH contacted me again yesterday
[14:03:22] <CaptHindsight> I sent them links to their own paper
[14:03:34] <kanzure> "Yes of course I will build this for you"
[14:04:49] <CaptHindsight> kanzure: it just needs better software
[14:04:55] <kanzure> oh?
[14:05:01] <MarcMarq> hi
[14:05:27] <kanzure> CaptHindsight: btw i recently funded an open-source ultrasound imaging device and an open-source electroporation device
[14:05:34] <MarcMarq> I'm trying to customize AXYS by changing how it display the the workspace.
[14:05:50] <CaptHindsight> a nice front end to turn a sequence into G-code and bitmaps for the printhead
[14:06:35] <MarcMarq> What i'm trying to do is change the line thickness, how I can do it?
[14:08:24] <MarcMarq> I have downloaded the source and made a search at the forum, but I didn't find nothig related with
[14:09:44] <MarcMarq> In other words I wanna customize the preview plot widget.
[14:10:01] <CaptHindsight> kanzure: just needs to be written without hearing the words *duino, GRBL, visual basic etc
[15:19:42] <tiwake> dododo

[15:31:23] <Deejay> are you digging for gold?
[15:38:06] <JT-Shop> trying to make a flat spot
[15:38:44] <Magnifikus> any good example for manual toolchange with tool probe before and after? getting confused
[15:40:22] <Frank_12> hi people
[15:40:44] <CaptHindsight> kanzure: the GUI and some of the back end need to be written
[15:41:20] <CaptHindsight> kanzure: and not like the turds that came out of the reprap projects
[15:42:50] <kanzure> okay. that's doable.
[15:43:30] <CaptHindsight> linuxcnc already does 90% of it
[15:44:42] <Magnifikus> https://github.com/koppi/mk/blob/master/linuxcnc/nc_files/tool-change.ngc this looks fine
[16:01:49] <andypugh> Magnifikus: Which version of LinuxcCNC are you uding?
[16:01:58] <andypugh> (using)
[16:04:36] <andypugh> Magnifikus: There is a sample config all ready to run in sim/axis/remap/manual-toolchange-with-tool-length-switch as part of the default installation.
[16:05:08] <Magnifikus> ah might be the machinekit from hell cause i run on rpi3
[16:05:18] <Magnifikus> so latest
[16:05:43] <andypugh> It’s a Michael Haberler config, it will be on Machinekit too.
[16:05:57] <Magnifikus> hehe okay :)
[16:17:20] <Deejay> gn8
[16:38:28] <KreAture_Zzz> Magnifikus how is the rpi3 working now ?
[16:38:34] <KreAture_Zzz> I had issues with it
[16:38:43] <KreAture_Zzz> Going to get it running on a BeeBox
[16:40:14] <Magnifikus> oh i have one running with rt-prempt/machinekit and fpga for stepgen over spi
[16:40:36] <KreAture_Zzz> hmz
[16:40:46] <KreAture_Zzz> On the rpi I'd almost demand it to use the gpio
[16:40:52] <KreAture_Zzz> it has so many of them
[16:41:21] <KreAture_Zzz> seems pointless to use the spi/fpga as then you could instead have a better gui/main control in a proper pc and still use the fpga
[16:41:39] <Magnifikus> nah the rt performance is like 50-80µs jitter
[16:41:46] <Magnifikus> no point in gpio stuff imho
[16:41:55] <KreAture_Zzz> hmm
[16:42:09] <KreAture_Zzz> The Beebox seems to do better than 35
[16:42:13] <KreAture_Zzz> so far anyway
[16:42:27] <Magnifikus> im just using it cause i got an fpga for realtime
[16:50:29] <andypugh> I got a Chip. But it’s still in the wrapper so nowhere near looking at latency tests: https://getchip.com
[16:51:14] <andypugh> I rather suspect it was beaten badly to market by Pi-zero. Which is also cheaper
[16:52:22] <SpeedEvil> And also not usually available
[16:52:31] <KreAture_Zzz> hehe hey SpeedEvil
[16:52:34] <SpeedEvil> hey
[16:52:39] <KreAture_Zzz> andypugh did you see the mainboard for the beebox ?
[16:53:15] <KreAture_Zzz> http://nucblog.net/wp-content/uploads/2015/10/ASRock_Beebox_motherboard_top.jpg
[16:53:21] <KreAture_Zzz> cpu is on bottom
[16:54:03] <KreAture_Zzz> adding the mPCIe board for the lpt it will cost a total of $330
[16:54:11] <KreAture_Zzz> with ram and disk
[16:54:27] <andypugh> No. I actually have far too many SBCs still in the packaging
[16:54:44] <KreAture_Zzz> That gives me a standalone machine capable of running linuxcnc with nice fast gui response as well as step pulses
[16:54:56] <KreAture_Zzz> in a enclosure
[16:55:20] <KreAture_Zzz> http://cdn.liliputing.com/wp-content/uploads/2015/05/beebox_02-e1431480414696-680x377.jpg
[16:55:39] <KreAture_Zzz> I will have to figure out how to get at the pins for the lpt after I install the mpcie though
[16:55:47] <KreAture_Zzz> I really want to leave it in the casing
[16:56:02] <KreAture_Zzz> It will be good for freecad too
[16:58:31] <andypugh> it’s cute, but are you so short of space that it wins over a Mini-ITX and PCI card?
[16:59:41] <andypugh> The only SBCs I look at are those with on-board GPIO in the hope that it is useful GPIO.
[17:02:44] <KreAture_Zzz> andypugh it is cheaper thn any mini itx or such around here
[17:02:49] <andypugh> I should have another look at my UDOO. That’s an X86 PC with an actual real Arduino Mega on the board and shared GPIO in Arduino layout
[17:03:20] <KreAture_Zzz> maby I should so fpga board for it and get the guys at work to model up an alternative cover plate too
[17:04:05] <KreAture_Zzz> real arduino mega my ass
[17:04:13] <KreAture_Zzz> it's a real atmega chip from atmel
[17:04:39] * KreAture_Zzz just gets annoyed by the lack of distinction
[17:05:32] <renesis> wtf is an arduino mega
[17:11:21] <andypugh> https://www.arduino.cc/en/Main/ArduinoBoardMega2560
[17:11:29] <andypugh> Arduino with more pins
[17:13:15] <andypugh> KreAture_Zzz: OK, so I am not sure where it stands in the Arduino / Genuino / Clone wars. But it can be used with Arduino.cc sketches and has the same pinout.
[17:14:49] <KreAture_Zzz> andypugh I don't bother about clones etc, I am just fed up that everyone glorifies arduino and forget that it is Atmel who made the single chip they use and that they already have a very good programming platform
[17:16:03] <Hydrar> I just had a problem with finding out how to use the avr-libc toolchain without the arduino env
[17:16:10] <Hydrar> And AVR Studio won't run on linux
[17:16:53] <KreAture_Zzz> that's true, they lack cross platform devtools
[17:17:38] <Sync> not really, avr gcc works well
[17:17:38] <malcom2073> KreAture_Zzz: Marketing is a bitch aint it? :)
[17:17:49] <Hydrar> Sync: Just a bit badly documented in some cases imo
[17:17:53] <KreAture_Zzz> malcom2073 yes
[17:17:55] <Hydrar> But yeah, I need to head off to bed
[17:18:09] <KreAture_Zzz> Sync yes gcc is nice but I do love a good ide
[17:18:22] <KreAture_Zzz> and do NOT say eclipse!
[17:18:34] <Sync> vim
[17:18:39] <KreAture_Zzz> hehe
[17:18:46] <malcom2073> vi
[17:18:50] <malcom2073> vim is for wusses
[17:18:52] <KreAture_Zzz> v ?
[17:18:53] <KreAture_Zzz> lol
[17:19:04] <KreAture_Zzz> all you need is cat
[17:19:14] <KreAture_Zzz> and sed
[17:19:18] <Sync> cat and echo
[17:25:33] <Magnifikus> and KreAture_Zzz my next experiment will be zynq :)
[17:25:42] <Magnifikus> with can open master in the fpga
[17:26:28] <Magnifikus> imho the zynq is the best thing for headless stuff with machinekit, kinda annoying that the gpu is nonexistant
[17:26:41] <Magnifikus> or you have to buy it
[17:26:59] <KreAture_Zzz> hmm
[17:27:16] <KreAture_Zzz> Magnifikus I am pondering doing a mPCIe board simply because I love the formfactor
[17:27:49] <KreAture_Zzz> Not sure how complex fpga is really needed
[17:28:02] <KreAture_Zzz> I don't know how the current fpgas are programmed
[17:28:19] <KreAture_Zzz> if they are basically doing PRU type service or what
[17:28:46] <KreAture_Zzz> n channels with options of being coded to send n pulses at x rate etc
[17:29:06] <KreAture_Zzz> or if they can handle a fifo buffered list of commands to queue up sequences
[17:29:13] <KreAture_Zzz> and if so, how is that good for homing etc
[17:29:36] <KreAture_Zzz> oh well sleepy time
[17:31:32] <Magnifikus> its basicly plain logic
[17:32:00] <Magnifikus> but with the higher languages you can create kinda nice statemachines etc
[17:32:06] <Magnifikus> this chip thingy is 25$ with hdmi
[17:32:15] <Magnifikus> so i would rather put 10$ ontop for a pi3 :)
[17:32:55] <Magnifikus> problem with the pi3 is the usb ethernet sucking your rt dry
[17:32:59] <Magnifikus> if you got alot of traffic
[17:33:33] <Magnifikus> like i tried socketcan but thats nono if you get ethernet traffic its get crushed even with interrupt priorities set etc
[17:33:35] <Polymorphism> do I really need harmonic drive???
[17:33:40] <Polymorphism> this looks expensive
[17:33:40] <Magnifikus> no
[17:34:37] <Magnifikus> and KreAture_Zzz https://github.com/magnifikus/TMC5130FPGA/blob/master/fpga/spartan3_ISE/stepgenerator.v thats how crude stepgenerator works in an fpga :)
[17:37:41] <andypugh> Polymorphism: If you are not sure you need one, then you probably don’t need one. But they are lovely. Where are you shopping? Set up a search on eBay for the part number you fancy, you might get one from someone who has no idea what it is.
[17:38:09] <Polymorphism> I was just looking to add 4th and maybe 5th axis to my machine
[17:38:18] <Polymorphism> something with enough holding power for aluminum
[17:40:05] <Magnifikus> large gear with wormdrive?
[17:40:59] <Magnifikus> dunno how low you can get backlash on a wormdrive
[17:41:20] <Polymorphism> harmonic drive has 0 backlash?
[17:41:35] <Polymorphism> https://www.youtube.com/watch?v=bzRh672peNk
[17:41:38] <Magnifikus> you complained it expensive
[17:42:07] <Polymorphism> it seems to be, but I don't want to get junk that wont work
[17:42:26] <malcom2073> You can get harmonic drives on ebay used for fairly cheap. We make 4th axises out of them
[17:43:49] <Magnifikus> ~300€ yeah
[17:43:53] <Polymorphism> thats not bad
[17:43:56] <Polymorphism> but thats just the harmonic drive right
[17:44:12] <Polymorphism> then I need a stepper, and the mounts and the chuck etc?
[17:44:24] <malcom2073> Magnifikus: Used, i think my dad got his last one for like $200USD
[17:44:29] <malcom2073> Polymorphism: Yes
[17:44:37] <Magnifikus> yeah was first look :)
[17:44:53] <malcom2073> Requires some engineering and machining to make it work, but they make fantastic 4th axis :)
[17:45:09] <Magnifikus> 5th :)
[17:45:16] <Magnifikus> oh that was later
[17:45:20] <malcom2073> That too heh
[17:45:34] <Magnifikus> wish i had a 4th for lab cnc
[17:45:40] <Magnifikus> turning would be damn sexy some times
[17:45:55] <Magnifikus> or turnmill
[17:46:16] <malcom2073> It is
[17:46:18] <Magnifikus> !seen the_saint
[17:46:18] <the_wench> Never heard of the entity the_saint you ask for
[17:46:19] <Polymorphism> I'd like to cut gears and knobs
[17:46:23] <Magnifikus> !seen thesaint
[17:46:23] <Polymorphism> not sure what else I need it for yet
[17:46:23] <the_wench> last seen in 2016-01-22 09:27:58GMT 838:59:59 ago, saying Ping timeout: 256 seconds
[17:46:26] <Polymorphism> but it cant hurt to have'
[17:46:27] <malcom2073> I haven't gotten mine built yet, but it's on my short list to make a trunion :)
[17:46:40] <Magnifikus> i want to make a 3d touch probe
[17:46:56] <Polymorphism> can I use the cnc to cut the parts to convert the harmonic drive to a 4th axis
[17:47:00] <Magnifikus> and alone making indexed holes for the center thingy with the arms is a challenge :)
[17:47:06] <Polymorphism> or is there a premade affordable setup
[17:47:31] <malcom2073> Polymorphism: I don't expect there is anything premade, as there are a *very* wide variety of harmonic drives you'll find on ebay
[17:47:39] <malcom2073> Almost infinite, considering they do custom drives all the time
[17:47:50] <Polymorphism> http://www.ebay.com/itm/CNC-4th-Axis-Router-A-Axis-100MM-Chuck-Gapless-Harmonic-Drive-Reducing-Gear-Box-/261858842965 something like this is no good then?
[17:48:12] <malcom2073> It's china, so unknown
[17:48:26] <malcom2073> It may be good?
[17:48:46] <Sync> thpse are ok Polymorphism
[17:49:01] <Sync> but you can get them for half the price
[17:49:18] <Magnifikus> yoou still need a nema23 stepper for 30$ :)
[17:50:57] <Polymorphism> https://www.youtube.com/watch?v=Cwq8ZZGX2As
[17:51:11] <Polymorphism> this looks like a nice setup

[18:00:53] <andypugh> (it’s a nice dial, but the music is a little over-dramatic )
[18:01:46] <Polymorphism> haha I was thinking that
[18:03:13] <Polymorphism> https://www.youtube.com/watch?v=joGv4ErUJgY whoever produced this video should be fired
[18:04:37] <Polymorphism> it doesnt get bad until :47
[18:04:58] <Polymorphism> no link for more details... backto ebay
[18:05:13] <Frank_12> guys, im building a gantry style router, rack and pinion, 2 motors on the long axis, and i've started to think about the rack setup, wont the pitch error from the racks unsquare the gantry? maybe causing the servos to overtorque? someone with any experience with this?
[18:06:08] <CaptHindsight> Frank_12: if you have that much pitch error you'd need to fix that anyway
[18:06:30] <Frank_12> i havent even bought the racks yet
[18:06:52] <Frank_12> its just a thought, to avoid the problem, before i have to fix it. hehe
[18:07:18] <CaptHindsight> Frank_12: some rack setups use 2 servos on each side. They keep load on each other to take out any lash
[18:07:55] <Frank_12> yeah, not an option to put 4 servos on 1 axis..
[18:08:01] <andypugh> Polymorphism: I applaud them in some ways, but feel they are over-selling a very obvious idea
[18:08:04] <CaptHindsight> http://machinedesign.com/motorsdrives/separating-rack-and-pinion-myths-reality
[18:08:36] <andypugh> Frank_12: What pitch error?
[18:08:44] <CaptHindsight> http://www.atlantadrives.com/systems1.htm
[18:08:50] <Frank_12> the plan was to spring load the pinion to the rack,
[18:09:10] <Frank_12> i've read that, but those racks are worth thousands i belive
[18:09:27] <enleth> I installed an ESP8266 in a vacuum cleaner today to be able to turn it on remotely over WiFi. All that's left now is some PVC pipe, fittings and hoses - and ESP-powered switches - to make a central vacuum cleaning system for the shop
[18:09:36] <CaptHindsight> I assumed he meant the difference in pitch between the two different racks
[18:09:37] <Frank_12> i dont know the pitch error, how do you measure it?
[18:09:44] <Frank_12> i did
[18:09:54] <CaptHindsight> gear pitch tolerance difference
[18:09:57] <Frank_12> if its the same in both racks then awesome, lol
[18:11:01] <CaptHindsight> split pinions with axial springs is another way
[18:11:32] <Frank_12> yes, but there we are talking backlash reduction,
[18:11:46] <Frank_12> not rack pitch error between racks of the same axis
[18:12:19] <andypugh> CaptHindsight: I have this idea of using double-helical rackks with double helical gears
[18:12:28] <Frank_12> lol
[18:12:41] <CaptHindsight> andypugh: think you told me about that before
[18:12:49] <andypugh> Then you just bias the gears axially for zero-backlash
[18:13:03] <Frank_12> on each side right?
[18:13:10] <andypugh> Yes
[18:13:23] <CaptHindsight> http://www.akronindustries.com/images/002%20Gears/3.Herringbone%20Gear/4.jpg
[18:13:39] <Frank_12> and i thought it was a joke... haha
[18:13:49] <andypugh> Anyway, I guarantee that any rack you buy will have a pitch error that your gantry wo’
[18:14:02] <andypugh> n’t even notice
[18:14:15] <Frank_12> its a stiff gantry,
[18:14:35] <Frank_12> 4xm8 bolts and 4xm10 bolts on each side
[18:14:40] <Frank_12> sorry, total
[18:15:03] <andypugh> Polymorphism: I wrote some G-code to engrave scale rings, if it’s any use to you.. https://forum.linuxcnc.org/forum/20-g-code/27169-g-code-to-engrave-numbers-on-cylinders#40497
[18:15:12] <CaptHindsight> most gantries are just floppy anyway
[18:15:22] <Polymorphism> I will bookmark it, ty
[18:15:27] <CaptHindsight> all that mass with not enough support
[18:16:29] <CaptHindsight> https://imagebin.ca/v/2apzmk7rpwvC I wouldn't cut much with these
[18:18:28] <Frank_12> i still have a hole with a tapp broken inside on the rack mount surface, T_T
[18:18:53] <Frank_12> i dont know if i should drill one next to it, or miss that bolt entirely,
[18:19:04] <Frank_12> 12cm between regular holes
[18:20:06] <CaptHindsight> http://cdn.snappages.com/d9ptdt/assets/2458169_2840125_1458052678.jpg split pinions with springs to push the two sides in opposite radial directions
[18:20:31] <CaptHindsight> some axial would also work
[18:20:38] <Frank_12> i dont think (havent tryed yet) that my gantry is going to give flex for a lot of pitch error,
[18:20:52] <Frank_12> i wonder if those racks/pinions are off the shelf
[18:21:03] <Frank_12> or easily available
[18:21:12] <CaptHindsight> yeah, but not at hobbyist prices
[18:21:17] <Frank_12> im about to buy steel for my second machine already haha
[18:21:29] <Frank_12> 200x200mm steel 9,5mm thick
[18:21:36] <Frank_12> sounds a lot hobby?
[18:21:47] <Frank_12> at least, its the biggest i can get in my country
[18:22:43] <andypugh> Frank_12: Glue a bolt head onto the hole with the broken tap. In time you will forget.
[18:23:46] <andypugh> (Not joking, I had almost fogotten, until just then :) )
[18:25:20] <roycroft> well enco have added insult to injury
[18:25:46] <roycroft> first they inform me that they are completing their integration into the msc borg collective
[18:26:13] <roycroft> and now they decided to send me another, unsolicited, copy of their 2014 catalog (the last one they published)
[18:26:29] <roycroft> and to make matters even worse, it was too big to fit in y box so i had to queue up for 15 minutes to get it
[18:26:58] <andypugh> Send it back. On fire.
[18:27:27] <Frank_12> "glue a bolt head into the hole with the broken tap", im not gettint the idea , means to just leave it like that? or you mean to drill and glue the same size bolt i need? meaning to drill the size of the head in the machine?
[18:27:44] <Frank_12> sorry, im still a noob, 23 years old this october... hehe
[18:27:58] <roycroft> take a bolt
[18:28:01] <roycroft> grind the head off
[18:28:08] <CaptHindsight> hide the broken tap with glue and head
[18:28:15] <roycroft> glue it in the hole that has the broken tap in it
[18:28:25] <roycroft> covering up the broken tap
[18:28:31] <roycroft> call it good
[18:28:39] <roycroft> in time you'll forget about it
[18:28:53] <roycroft> it was pretty clear to me :)
[18:29:20] <andypugh> Yeah, purely a cosmetic excercise, but you probly don’t need ebery bolt.
[18:29:26] <andypugh> (every)
[18:29:29] <roycroft> bolts are overrated
[18:29:39] <roycroft> especially chinese ones
[18:29:49] <roycroft> wait
[18:29:55] <roycroft> china are making halfway decent stuff now
[18:30:05] <roycroft> especially vietnamese ones
[18:30:08] <roycroft> there, that's better
[18:30:12] <Polymorphism> china will make whatever you need, just choose how much to pay
[18:30:25] <Polymorphism> trhey will make crap if you want to pay crap price xD
[18:31:16] <roycroft> so i am going to be machining a 1/2" thick plate of 6061
[18:31:19] <Frank_12> oh come on guys if its just cosmetic then the hell with it, i might leave it like that and cover it with the rack! hahaha
[18:31:20] <roycroft> mostly that's going to be fine
[18:31:44] <roycroft> but there are three holes that i need to drill and tap in the plate, and the fasteners will be removed frequently - several times/day
[18:31:58] <roycroft> aluminium threads are not going to last long
[18:32:13] <roycroft> would helicoil inserts work reasonably well?
[18:32:42] <Frank_12> i've read (0 experience) that they are even better that steel threads
[18:32:56] <Polymorphism> what about aluminum gears?
[18:33:04] <CaptHindsight> https://youtu.be/dcQMNY2QD88?t=2m6s these giant lathes use dual servos on the rack for preload
[18:33:08] <Frank_12> because they split the effort into more threads rather than the first few when tapping
[18:33:17] <roycroft> frank_12: google "EDM"
[18:33:41] <roycroft> my concern is not the longevity of the helicoils themselves
[18:33:44] <roycroft> i'm sure they would be fine
[18:34:06] <roycroft> but would they tend to come loose over repeated fastening/unfastening cycles such as they would experience on my part?
[18:34:12] <Frank_12> you like electronic dance music or electrical discharge machining? haha
[18:34:26] <roycroft> that's up to you
[18:34:33] <roycroft> are you intending to celebrate your broken tap or remove it?
[18:34:52] <CaptHindsight> I'm more into Heavy Metal :)
[18:35:12] <roycroft> my bagpipe has some shiny metal ferrules on it
[18:35:18] <roycroft> and it's kind of heavy
[18:35:28] <BeachBumPete> CaptHindsight I had you pinned more for the Yanni type ;)
[18:36:05] <CaptHindsight> what do you use the bagpipes for? Chasing people off your property?
[18:36:24] <roycroft> annoying my cats, primarily
[18:36:33] <CaptHindsight> not fans eh
[18:36:43] <roycroft> take an empty room
[18:36:46] <roycroft> with zero furniture
[18:36:51] <roycroft> zero draperies
[18:36:56] <roycroft> just a big rectangle
[18:36:59] <roycroft> insert two cats
[18:37:05] <roycroft> walk in with bagpipe
[18:37:13] <roycroft> close door so that cats cannot escape
[18:37:15] <Frank_12> i will defenetively have to check more on reliable accurate and stiff transmision for my second machine, as for this one, a WOOD cnc router 8x4 feet i think rack pinion spring preload or something like that will be fine, i mean the gantry only weights 130kg
[18:37:16] <roycroft> start playing bagpipe
[18:37:19] <roycroft> cats will disappear
[18:37:47] <roycroft> how they can do that is one of life's unsolvable mysteries
[18:37:58] <Polymorphism> if you tape buttered toast to a cats back and throw it off a roof it won't die
[18:38:06] <enleth> roycroft: doesn't bagpipe itself sound somewhat like a cat being squeezed in the armpit while someone tries to blow in its tail?
[18:38:08] <Polymorphism> as long as you tape it buttered side up
[18:38:15] <roycroft> only when played poorly
[18:38:20] <Polymorphism> I can't confirm this, and am not liable if anyone attempts it
[18:38:34] <roycroft> that's a perfect description of a perpetual motion machine
[18:38:40] <CaptHindsight> how do you know when a bagpipe is out of tune?
[18:38:52] <enleth> it produces sound, duh
[18:38:55] <Polymorphism> ha
[18:38:57] <roycroft> if you could harnass the rotational energy of the cat you could retire comfortably
[18:38:59] <BeachBumPete> tune? whats a Tune?
[18:39:00] <Frank_12> lol
[18:39:02] <Polymorphism> xD
[18:39:12] <CaptHindsight> similar to banjos
[18:39:22] * roycroft also has a banjo
[18:39:25] <Frank_12> stop it nerds
[18:39:26] <Frank_12> haha
[18:39:34] <BeachBumPete> I got a Ukelele
[18:39:36] <roycroft> and a mandolin
[18:39:40] <roycroft> ukulele
[18:39:48] <BeachBumPete> and a six string
[18:39:55] <BeachBumPete> can't play either.....yet
[18:40:19] <roycroft> tiptoe, through the window
[18:40:24] <roycroft> to the garden, that's where i'll be
[18:40:30] <roycroft> just tiptoe through the tulips, with me
[18:40:32] <BeachBumPete> I can play the hell out of a saxophone but I DON'T have one of those anymore
[18:40:50] <roycroft> probably most of you aren't old enough to remember tiny tim
[18:41:08] <Frank_12> i can open youtube...
[18:41:09] <CaptHindsight> old banjo joke: I left my banjo on the seat of my locked car and left. When i came back the window was smashed and there were 2 banjos the seat.
[18:41:31] <andypugh> Bagpipes: https://www.youtube.com/watch?v=Mwxga8udIio Lovely.
[18:41:31] <BeachBumPete> I like dulcimers tho those are pretty cool
[18:42:02] <roycroft> https://www.youtube.com/watch?v=zcSlcNfThUA
[18:42:03] <CaptHindsight> is a dulcimer a guitar on its side?
[18:42:20] * JT-Shop can't carry a tune in a sack
[18:42:34] <roycroft> i'm not sure i could play uillean pipes
[18:42:36] <BeachBumPete> http://www.dulcimer.net/wp-content/uploads/2016/04/Roosebeck-DMCRT4-4-String-Cutaway-Mountain-Dulcimer-F-Hole-Openings-and-Scrolled-Pegbox-686x1024.jpg
[18:42:42] <roycroft> even more difficult than the great highland bagpipe
[18:42:52] <roycroft> but a lovely instrument
[18:44:42] <roycroft> so any ideas besides helicoils for my part?
[18:44:48] <roycroft> or is helicoil the best option?
[18:45:03] <CaptHindsight> https://www.youtube.com/watch?v=V8e_vpSNHtg "FĂĽr Elise" with stepper motors
[18:45:28] <andypugh> roycroft: Sorry, I missed the question
[18:45:58] <roycroft> i'm making a part out of 1/2" 6061
[18:46:23] <roycroft> i need to drill and tap three holes for fasteners that will be removed/reinstalled frequently - several times/day
[18:46:48] <roycroft> i don't think the aluminium will hold up for long, so i'm thinking of some kind of more durable insert
[18:46:51] <CaptHindsight> roycroft: I take it that these are not Scottish cats
[18:46:53] <roycroft> helicoil comes to mind
[18:47:16] <roycroft> and the insert itself would be durable enough
[18:47:24] <roycroft> but i my concern is that it may come loose over time
[18:47:31] <Frank_12> i dont think so,
[18:47:33] <roycroft> and i'd find myself removing the helicoil with the bolt
[18:47:44] <andypugh> Can you use a stainless steel insert from the back?
[18:47:53] <roycroft> if it were flush
[18:47:58] <andypugh> (Custom-made)
[18:48:02] <Frank_12> the helicoil is glued or threaded a size over?
[18:48:17] <zeeshan> todays biggest lesson: never trust a friend's machine shop
[18:48:20] <zeeshan> :/
[18:48:21] <roycroft> a helicoil plus loctite might work
[18:48:27] <Frank_12> epoxy ?
[18:48:27] <roycroft> especially if it's the red loctite
[18:48:34] <andypugh> I don’t mean a helicoil, I mean a solid top-hat shaoped thing
[18:48:42] <roycroft> yes, i know what you mean
[18:48:48] <CaptHindsight> someone actually wrote a MIDI to G-code generator
[18:48:57] <CaptHindsight> http://en.homeconstructor.de/create-music-with-cnc-milling-machine.html#Konverter
[18:49:15] <roycroft> actually, i could make something like that and mill a recess into the back of the plate to make it flush
[18:50:15] <roycroft> the flange would not need to be very thick
[18:50:23] <andypugh> Indeed not
[18:50:47] <roycroft> and i could drill three holes in the flange and hold it in place with some tiny flat head screws
[18:51:24] <roycroft> the whole thing would still be flush, and i'd have threads for the full thickness of the plate
[18:51:34] <andypugh> I would thread the outside and trap it between the plate and the backing
[18:51:41] <roycroft> making the top-hate thing without a lathe might prove challenging
[18:51:47] <roycroft> hat
[18:51:55] <andypugh> (or maybe use one screw)
[18:52:25] <roycroft> i have a '65 vw bus that i've been meaning to sell for a long time
[18:52:41] <andypugh> roycroft: http://www.pvrdirect.co.uk/sealey-vs311-01-thread-inserts-m8-x-1mm-for-vs311-pack-of-5/?CAGPSPN=pla&CAAGID=25337172250&CATCI=pla-54458723577&catargetid=120134430000000121&cadevice=c&gclid=CITis42xzs0CFXEz0wod1X0MSQ
[18:52:45] <roycroft> i should just use this project as inspiration to finally sell the damn thing, so i can get a new lathe
[18:52:57] <Polymorphism> lol
[18:53:12] <zeeshan> how would you guys machine 7 holes on square tubing that are in line but their distance varies. .. one is 10.625" apart +/- 0.005, another 11.231+/-0.005 another is 14.875" +/-0.005 apart. then the part is mirrored
[18:53:20] <zeeshan> overall length of square tube is 76"
[18:53:54] <roycroft> something like that would work great, andypugh
[18:53:55] <roycroft> thanks
[18:53:57] <zeeshan> my machine travel is only 15.75"
[18:54:08] <roycroft> but if i got some of those i would not need to buy a new lathe
[18:54:28] <andypugh> Sorry. But then you do get to keep the bus.
[18:54:42] <roycroft> i want to keep it, sort of
[18:54:51] <roycroft> my plan was to convert it to an ev
[18:54:52] <Polymorphism> http://www.aliexpress.com/item/Free-shipping-3-jaw-Chuck-100mm-CNC-4th-axis-harmonic-drive-for-cnc-miiling-machine-Rotary/32662514333.html?spm=2114.01010208.3.57.M0uPW4&ws_ab_test=searchweb201556_0,searchweb201602_4_10017_405_404_301_507_10040,searchweb201603_7&btsid=8513832e-30a1-4b92-bfe1-83878fa3e076
[18:54:55] <Polymorphism> thats the best deal I can find
[18:55:04] <roycroft> but i'm getting old
[18:55:14] <Polymorphism> http://www.aliexpress.com/item/Free-shipping-harmonic-drive-reducer-3-Jaw-50mm-chuck-CNC-dividing-head/1000001760103.html?spm=2114.01010208.3.33.M0uPW4&ws_ab_test=searchweb201556_0,searchweb201602_4_10017_405_404_301_507_10040,searchweb201603_7&btsid=8513832e-30a1-4b92-bfe1-83878fa3e076 or this
[18:55:15] <roycroft> and i do not enjoy working on vehicles much any more
[18:55:30] <roycroft> realistically, i'll probably never do that conversion
[18:55:39] <roycroft> and the bus is going to start rusting before long
[18:55:46] <Frank_12> a tesla vw?
[18:55:47] <roycroft> it continues to appreciate in value for now
[18:55:55] <roycroft> but once it starts rusting it will rapidly decrease in value
[18:56:45] <roycroft> so i could get thread inserts like that
[18:57:06] <roycroft> drill one hole at the very edge of an insert, and hold it in place with a single screw
[18:57:15] <roycroft> that would probably work fine
[18:57:35] <roycroft> and likely, using red loctite would suffice to hold the inserts in place
[18:58:03] <zeeshan> talking to me?
[18:58:07] <zeeshan> you just gave me an awesome idea.
[18:58:14] <roycroft> i wasn't
[18:58:16] <roycroft> but sure :)
[18:58:18] <zeeshan> but you did
[18:58:18] <zeeshan> lol
[18:58:19] <Polymorphism> lol!
[18:58:19] <zeeshan> thats funny
[18:58:34] <zeeshan> i could use an insert
[18:58:36] <zeeshan> to mark the holes
[18:58:41] <zeeshan> with the various hole distances
[18:58:43] <roycroft> are you saying that random mindless banter is sometimes useful?
[18:58:44] <zeeshan> thank you!
[18:59:38] <roycroft> my braking resistor is here
[18:59:43] <roycroft> i shall have to go test
[18:59:56] <roycroft> but i'm having dinner and drinks with friends soon, so i'll wait until after
[19:00:09] <roycroft> wiring up the vfd after a couple mojitos will be more exciting anyway
[19:05:44] <zeeshan> man i love youtube
[19:05:47] <zeeshan> im going into the bush for a week
[19:05:59] <zeeshan> i got an awesome idea on how to setup a bear trip alarm
[19:06:06] <zeeshan> theyre using those personal rape alarms
[19:06:10] <zeeshan> connected to a string
[19:06:13] <zeeshan> to pull out the pin :)
[19:08:03] <roycroft> https://www.kent-automotive.com/kent/Diamond-Grip-II-Threaded-Insert-Standard-Flange/94736.ka
[19:08:06] <roycroft> these might work
[19:08:30] <roycroft> they're press-fit, but claim to withstand the torque rating of a grade 5 bolt
[19:08:58] <roycroft> is bear rape a serious problem?
[19:10:37] <andypugh> roycroft: Those actually expect to be “squish fit” for want of a better term
[19:11:22] <andypugh> Look at the third (installed) picture
[19:11:56] <zeeshan> roycroft: theres a lotta bears where im goin
[19:12:04] <enleth> roycroft: bear rights advocates sure seem to think so
[19:12:07] <roycroft> aah, yes, i see
[19:12:24] <roycroft> i have a hydraulic press
[19:12:29] <roycroft> squish fitting can be done
[19:12:30] <zeeshan> https://www.youtube.com/watch?v=Vt_ZATda2XU
[19:12:33] <zeeshan> this is exactly what im building
[19:12:35] <zeeshan> just 3 of them
[19:12:40] <zeeshan> spread over 200 ft
[19:12:51] <enleth> roycroft: do you have a heavy russian or finnish accent as well?
[19:13:07] <enleth> if not, it's not a youtube-grade press
[19:13:09] <andypugh> roycroft: But they are also intended for thin sheet. I don’t think that they suit your application
[19:14:01] <roycroft> oh, the grip range is limited
[19:14:58] <andypugh> Custom flanged things with three screws on the back side (as you suggested) is probably the best idea, really.
[19:16:17] <roycroft> the alternative would be through holes and nuts on the back
[19:16:25] <roycroft> but i want to be able to do changes without requiring tools
[19:16:35] <roycroft> which is why i don't want to do that kind of setup
[19:17:04] <roycroft> besides, it's not very elegant
[19:17:22] <roycroft> even when making machinery, elegance counts
[19:17:31] <roycroft> perhaps it's even more important when making machinery
[19:18:29] <andypugh> Hmm, is machining hexagonal holes in the back and using actual nuts an option?
[19:18:49] <roycroft> i've thought of that too
[19:19:02] <roycroft> i could machine close to hexagonal holes, and clean up the corners
[19:19:02] <zeeshan> roycroft: what are you trying to do
[19:19:17] <roycroft> i need to drill and tap holes in some 1/2" aluminium plate
[19:19:29] <roycroft> the fasteners will be removed and reinserted several times/day
[19:19:45] <roycroft> so i want the threads in the plate to be more durable than just 6061
[19:19:54] <andypugh> roycroft: Just mill deeper in the corners, it will still work
[19:20:07] <roycroft> it is aluminium
[19:20:12] <roycroft> so it's like milling butter
[19:20:15] <zeeshan> roycroft: i highly suggest cold forming
[19:20:33] <roycroft> if i left the corners rounded i could just press the hex nuts in
[19:20:42] <zeeshan> way stronger than regular tapping
[19:20:56] <roycroft> i'm looking at some kind of insert
[19:21:13] <zeeshan> what diameter is the hole
[19:21:13] <zeeshan> er
[19:21:15] <zeeshan> threead
[19:21:52] <roycroft> two will be 5/16" (8mm), one will be 3/8" (9.5mm)
[19:22:09] <zeeshan> darn
[19:22:51] <zeeshan> one thing ive done in the past
[19:23:04] <zeeshan> which is more involved but is really serviceable
[19:23:20] <zeeshan> make a flanged plate that fits inside the aluminu
[19:23:27] <zeeshan> (bolts down)
[19:23:43] <roycroft> that's an idea
[19:23:45] <zeeshan> w/ flat socket screws
[19:23:54] <roycroft> andypugh was suggesting a threaded insert with a flange
[19:24:01] <zeeshan> yea it works well
[19:24:05] <zeeshan> just time
[19:24:07] <roycroft> but i don't have a working lathe right now
[19:24:17] <roycroft> which makes fabrication a bit more challenging
[19:24:18] <zeeshan> me either
[19:24:22] <zeeshan> i do all my round shit on the mill
[19:24:22] <zeeshan> :D
[19:24:28] <roycroft> but a plate would be pretty easy - just a little mill work
[19:24:35] <roycroft> i don't have a rotary table at the moment either
[19:24:41] <roycroft> the one i want is on backorder
[19:24:52] <andypugh> I can’t imagine how miserable life would be without a lathe.
[19:25:09] <roycroft> i'd rather have a lathe and no mill than vice versa
[19:25:14] <roycroft> but vice versa is what i have
[19:25:34] <andypugh> I have heard that some people exist that way, but I wouldn’t really call it “living” :-)
[19:26:02] <Sync> zeeshan: get the lathe running already
[19:26:04] <roycroft> the lathe i wan't isn't all that expensive
[19:26:07] <zeeshan> sync no
[19:26:11] <zeeshan> my rx7 is almost ready
[19:26:12] <zeeshan> im so excited
[19:26:13] <zeeshan> :)
[19:26:24] <roycroft> but it's more than i want to finance, and more than the cash i have in my pocket
[19:26:27] <Sync> what is the subie doing?
[19:26:30] <roycroft> that vw bus is worth $6k
[19:26:34] <zeeshan> subie is gone
[19:26:36] <Sync> ah
[19:26:48] <Sync> getting ready to drop the 4g93 into the colt
[19:26:51] <andypugh> Time to log, methinks.
[19:26:53] <zeeshan> sync nice
[19:26:57] <zeeshan> i saw an eagle talon today
[19:27:01] <zeeshan> i miss 4g63 t :(
[19:27:02] <roycroft> so if i ever get around to selling it i can get the lathe, and a fair amount of tooling, and still have cash left over
[19:27:16] <roycroft> i should just get up off my butt and sell the thing
[19:27:29] <roycroft> the problem is it won't sell locally
[19:27:39] <roycroft> people around here still think that old vw buses are worth $999
[19:27:39] <Sync> if I get an awd colt or find the rear subframe I'll go 4g63t
[19:27:42] <roycroft> er, $900
[19:27:51] <roycroft> but folks back east will pay big bucks for them
[19:28:12] * roycroft heads off to dinner
[19:29:00] <Frank_12> guys, is there an option to make something like this, with like an off the shelf bearing cage? http://imgur.com/gAYUNUE
[19:29:20] <Sync> because it would be super useless to keep it 2wd zeeshan
[19:52:00] <Tom_itx> zeeshan how much tension can you put on the keychain before it goes off?
[19:52:10] <Tom_itx> too much line sag over that distance?
[19:55:39] <zeeshan> it takes a good 5lb
[19:55:40] <zeeshan> to pull it out
[19:55:41] <zeeshan> or so
[19:59:19] <zeeshan> Tom_itx: http://i.imgur.com/TPP4sK4.jpg
[20:22:55] <skunkworks> https://www.youtube.com/watch?v=2BFTifZgQVs
[20:36:39] <zeeshan> skunkworks: howd you dial in the angle
[20:36:41] <zeeshan> for #40?
[20:37:17] <malcom2073> skunkworks: Awesome!
[20:39:26] <skunkworks> bt35
[20:39:49] <skunkworks> zeeshan, strictly the taper 7/24
[20:39:59] <zeeshan> how do you align
[20:40:00] <skunkworks> it cut the same all the way up..
[20:40:02] <zeeshan> the dremel to it tho?
[20:40:47] <skunkworks> align? only alignment was making sure the dremel was centered to the spindle
[20:41:10] <zeeshan> oh
[20:41:12] <zeeshan> you move the xy table
[20:41:17] <zeeshan> er
[20:41:21] <zeeshan> xz or whatever
[20:41:31] <zeeshan> to get the taper
[20:41:31] <skunkworks> yz
[20:41:38] <zeeshan> gotcha :D
[20:41:41] <skunkworks> yes - x is centered on the spindle
[20:41:42] <zeeshan> that makes sense!
[20:43:22] * skunkworks was suprised it worked as well as it did..
[20:43:48] <zeeshan> :D
[20:43:51] <zeeshan> it looks proper!
[20:44:49] <skunkworks> we think 30 years of tool changes shaped the taper
[20:45:27] <skunkworks> bluing a tool and sticking it in the taper showed some odd high points
[20:46:21] <zeeshan> i always clean the tool before putting in the tool
[20:46:29] <zeeshan> i feel like the smallest chip will do some weird crap
[20:47:21] <malcom2073> +1 for that, I wipe it down
[20:49:51] <skunkworks> with the tool changer - we have it programmed to push air through the spindle as the tool goes back in the spindle
[20:52:24] <cradek> skunkworks: did it change so little that the tool holder still sticks out the right amount?
[20:54:57] <skunkworks> yes..we at the most took out .002"
[20:56:14] <skunkworks> the tool flange still has a gap between it and the spindle
[20:56:20] <cradek> ah good
[20:56:24] <skunkworks> probably .05? maybe less
[20:56:45] <cradek> .002 off the taper seems like it would change the stickout quite a bit
[20:57:59] <skunkworks> I didn't do the math.. we don't know how much the first pass took after that we moved it about .001)
[20:58:20] <skunkworks> it is .35 over 2.4 inches
[20:58:29] <cradek> yeah if one of us had a high school education we'd be able to do that trig
[20:58:37] <skunkworks> so probably not as much as you think
[20:58:50] <cradek> well if the arm still works it's perfect
[20:58:53] <skunkworks> I would have caded it ')
[20:59:32] <cradek> heh
[21:00:08] <cradek> weird, tormach has a cnc surface grinder that uses belt-sander belts
[21:00:28] <malcom2073> How do you dress a belt?
[21:00:29] <skunkworks> Really? I haven't seen that.
[21:00:37] <cradek> https://www.youtube.com/watch?v=5pPYgZ0lB1g
[21:00:50] <cradek> yeah that's the first question that comes to mind for me too
[21:01:21] <malcom2073> I mean... for a manual surface grinder ok you may not need dressing, but I thought with CNC the whole idea was to dress it, sorta like touching off yeah?
[21:02:14] <cradek> I don't know how you could get it flat (and in this video you can clearly see the stepover in the work)
[21:03:01] * cradek shrugs
[21:04:00] <skunkworks> I wonder if that is an attachment..
[21:04:59] <cradek> looks like a totally different machine (maybe with a few parts in common)
[21:05:16] <skunkworks> http://www.tormach.com/product_psg_612.html
[21:06:03] <cradek> ah maybe the wheel is the normal setup
[21:24:56] <CaptHindsight> skunkworks: was the inside of the spindle just worn or was it just made out of round?
[21:25:46] <CaptHindsight> ah "we think 30 years of tool changes shaped the taper"
[21:26:37] <skunkworks> yes? ;)
[21:27:32] <CaptHindsight> I have to change the spindle bearings in mine
[21:27:52] <malcom2073> We have a bridgeport at work, and it makes some noise when you start to load it down, thinking it might need spindle bearings
[21:32:45] <Duc> maybe. Mine only sounds right under load
[21:33:00] <Duc> I think the spline adapter up top might be a loose fit
[21:33:10] <malcom2073> This one is fairly quiet... suprising for the bag of bolts that varidrive is
[21:33:25] <malcom2073> Except when cutting, it makes... bad bearing noise heh
[21:33:41] <Duc> what about a heavy load cut
[21:33:58] <malcom2073> Sounds worse the heavier the load
[21:34:29] <Duc> ton of chatter on surface?
[21:34:36] <malcom2073> doesn't actually look bad
[21:34:41] <malcom2073> like, fairly smooth
[21:34:53] <malcom2073> The handle *feels* bad though when turning
[21:35:29] <Duc> the handle?
[21:35:50] <malcom2073> Oh, it's a manual mill
[21:35:56] <malcom2073> old bridgeport heh
[21:36:08] <malcom2073> They don't let me play with the mattura at have
[21:36:31] <Duc> I bought my bearings from H&W when I did mine
[21:36:46] <malcom2073> Eh, I expect if these are bad, they'll get rid of the mill at some point
[21:36:56] <Duc> can you take it home?
[21:37:03] <malcom2073> They don't seem concerned with maintaining the shop unfortunatly, I'm one of the few that uses it. Once it goes, they'll jsut outsource everything
[21:37:05] <malcom2073> No :(
[21:37:14] <malcom2073> Whcih is a shame, because there's a broken knee CNC mill that is *DAMN* nice that I want
[21:37:23] <malcom2073> box ways and all
[21:38:27] <Duc> dam
[21:38:30] <malcom2073> I'm gonna see if I can weasle my way into that one if they get rid of it. Floppy drive broke on it so the control is out
[21:38:41] <Duc> suprised work is so against that stuff
[21:38:55] <Duc> can you buy it
[21:38:59] <malcom2073> We've downsized a *lot*, almost nobody left who knows how to use it
[21:39:13] <malcom2073> Nah, corporate policy says all trash has to be scrapped.... but I'm friendly with the scrap yard
[21:39:32] <Duc> have them come get it and take it to your house
[21:39:46] <malcom2073> Problem is: They charge $0.50 per lb for steel
[21:39:51] <malcom2073> if I want to "buy" something from the scrap yard
[21:39:58] <malcom2073> that'd be a $1500 mill... but it'd totally be worth it still
[21:40:03] <Duc> what is it
[21:40:19] <malcom2073> I'm trying to remember the name so I can find a picture
[21:41:03] <malcom2073> Ah! It's an Acer
[21:41:04] <Duc> it amazing how much you can grease the palms of the owner of the scrap yard
[21:41:27] <malcom2073> http://gempel.com/em-supracnc3a-lg.jpg
[21:41:28] <malcom2073> One of them
[21:41:36] <malcom2073> Identical to that
[21:41:50] <Duc> we have 2 of the manual machines at work
[21:42:27] <Duc> one sounds like a rock crusher while running. we did have to tig the pulley keyway back together so its understandable
[21:42:43] <malcom2073> Heh
[21:43:13] <Duc> key stock was able to rotate in pulley before we fixed it
[21:43:18] <malcom2073> Oh man heh
[21:43:18] <malcom2073> nice
[21:43:53] <Duc> they are ok machine but if you have to buy the machine eh
[21:43:57] <Duc> hard to find parts
[21:44:23] <malcom2073> hm
[21:44:26] <Duc> we used to have a ACER VMC that used to fail randomly, Z loved to rapid into fixtures
[21:44:34] <malcom2073> Oh joys.
[21:44:41] <malcom2073> I'd replace the control with linuxcnc+mesa
[21:44:46] <malcom2073> since it's servo
[21:44:48] <Duc> long gone
[21:44:55] <malcom2073> no I mean if I get this one
[21:45:00] <Duc> even the auction house guy couldnt get it fixed right
[21:45:13] <Duc> what area do you live
[21:45:19] <malcom2073> North central maryland
[21:47:57] <Duc> http://www.ebay.com/itm/Bridgeport-Interact-412-milling-machine-VMC-/112042456900?hash=item1a16403744:g:60MAAOSwXeJXc~CR
[21:48:37] <Duc> I have the open boss5 and I get chips and coolant everywhere
[21:48:45] <malcom2073> Oh I don't NEED a mill, I have a working cnc knee mill :P
[21:50:18] <Duc> a big one?
[21:51:34] <malcom2073> Eh, 3200lbs. It's an old Clausing Kondia
[21:51:57] <malcom2073> stepper conversion, it's got about a 15x24" throw
[21:55:03] <Duc> thats not to bad
[22:01:04] <malcom2073> Nah, it's pretty good. I'm working on a big router for larger stuff
[22:03:50] <Duc> I still need to decide if Im going to fix the CNC router I have or upgrade it
[22:06:22] <malcom2073> The technoisel?
[22:06:26] <malcom2073> Was that you?
[22:07:14] <roycroft> hmm
[22:07:28] <roycroft> so the salvadoran place where we were going to go is closed for a week
[22:07:34] <roycroft> so no mojitos
[22:07:39] <roycroft> but we went to a tapas bar
[22:07:52] <roycroft> and had several pitchers of sangría
[22:08:20] <roycroft> i wonder if that makes me more or less prepared to test my braking resistor this evening
[22:09:01] * roycroft thinks it could be heaps of fun
[22:10:01] <Duc> malcom2073: yes
[22:10:19] <malcom2073> My dad just picked up a second small davinchi for like $250, he's got two now
[22:12:34] <Duc> how is it
[22:19:43] <Duc> bedtime
[23:10:35] <roycroft> well maybe not heaps of fun
[23:10:37] <roycroft> just boring
[23:10:53] <roycroft> the dump resistor has zero effect
[23:11:31] <roycroft> not what i expected
[23:54:20] <roycroft> so it appears that many of the huanyang vfds are missing the brake resistor circuitry
[23:54:31] <roycroft> even though it's documented
[23:55:14] <roycroft> so i may need to buy a transistor, diode, and capacitor to get the braking circuitry working
