[00:00:25] <enleth> that makes sense
[00:00:30] <toastydeath> a good rotary table has a very weird looking worm/wheel pair and is cut to have very very low backlash
[00:00:35] <toastydeath> and is often adjustable
[00:00:56] <enleth> I've never had an opportunity to take apart either of those so I couldn't spot the difference
[00:01:20] <toastydeath> dividing heads usually have very large ratios on the thing, like 40:1
[00:01:35] <toastydeath> whereas rotary tables have substantially smaller ratios, 10:1, 5:1, 4:1
[00:01:58] <toastydeath> i forget the technical name for it, i think it's called a double profile or double relief worm/wheel pair
[00:02:18] <toastydeath> where the profile of the wheel blank is cut into the worm, and the profile of the worm blank is cut into the wheel
[00:02:33] <toastydeath> so you get this kinda parabolic worm, and a circular cutout in the teeth of the wheel
[00:02:49] <toastydeath> and then some mechanism for adjusting backlash
[00:03:15] <toastydeath> less accurate but can hold more force/less wear under load
[00:04:27] <enleth> OK, thanks for the info

[00:32:02] <bensbenz> jt-shop so I did some testing and it looks like something is in fact working. If I measure the voltage from my BOB on the step pin, it does in fact go up and down, but its like .01 V to .110 and then it stops
[00:32:11] <bensbenz> so it must be the scale factor then?
[00:32:56] <bensbenz> should be like 0-5v which the spindle control board would change to 0-10 for the vfd

[03:45:33] <pink_vampire> bensbenz: I see that you make the belt drive conversion.
[03:46:10] <bensbenz> pink_vampire yea thats a must in my book, first one was a timing belt, but that was noisy and had a lot of vibration
[03:46:17] <os1r1s> bensbenz Do you have some special enclosure?
[03:46:32] <pink_vampire> you get any benefit from it over the gear?
[03:46:38] <bensbenz> pink_vampire now I have a v belt setup that gives me a max 13k rpm
[03:46:59] <bensbenz> less noise, smoother and much faster
[03:47:08] <pink_vampire> what is the speed of the motor?
[03:47:56] <bensbenz> os1r1s not too special, I just had my brother in law bend up some sheet metal to surround it, I havent made the doors yet
[03:48:57] <bensbenz> pink_vampire is a 1.5 HP AC with a KB genesis VFD and 3450RPM
[03:49:09] <pink_vampire> I didn't get how the belt drive connect to the machine
[03:49:55] <bensbenz> pink_vampire I machined custom pulleys, one fits the spline of the spindle at the top.
[03:50:06] <bensbenz> I removed all the gears inside
[03:51:30] <pink_vampire> you make the pulley on the G0704 or on a lathe?

[04:21:03] <bensbenz> 1/4 high helix 3 flute
[04:21:44] <bensbenz> when I am running on the 10k pulley the max dia I can run is like 5/16
[04:21:53] <os1r1s> bensbenz I've been pushing those with my taig and it struggles. That looks like butter
[04:22:15] <bensbenz> yea its nothing on this mill for 1/4 esp with HSm paths
[04:22:52] <bensbenz> really chip thinning is the savior of the small mill
[04:23:02] <os1r1s> bensbenz Did you have to do a lot of work to clean up your G0704?
[04:23:02] <bensbenz> what cam are you using?
[04:23:16] <os1r1s> bensbenz I've used fusion360 and bobcad.
[04:23:27] <bensbenz> ha good fusion360 is amazing
[04:23:32] <os1r1s> I prefer bobcad when it suits the job
[04:24:00] <bensbenz> it wasnt too bad, a lot of disassembly
[04:24:11] <pink_vampire> bensbenz: how is fusion360 vs hsmworks?
[04:24:32] <pink_vampire> now I'm with hsmexpress.
[04:24:36] <os1r1s> bensbenz Did you have any bad parts, or just ones you needed to lap?
[04:24:46] <os1r1s> pink_vampire HSM express doesn't have the 3d pathing he uses
[04:24:56] <pink_vampire> I know.
[04:25:01] <os1r1s> HSM full is very nice. Both HSM and fusion use the same core
[04:25:21] <pink_vampire> hsmworks is the full version of hsmexpress..
[04:25:25] <os1r1s> fusion360 is a cheap way to get the 3d pathing from HSM full
[04:25:54] <pink_vampire> so it's better to go with hsmworks?
[04:26:47] <bensbenz> pink_vampire I perfer fusion360 even to hsmworks
[04:26:59] <os1r1s> bensbenz How come?
[04:27:02] <bensbenz> I used to use hsmworks, but i like cad in fusion better than SW
[04:27:32] <bensbenz> its just a nicer package imho, and I can model fast in fusion
[04:27:49] <bensbenz> the only negative is that hsmworks gets things sooner that fusion
[04:28:11] <os1r1s> bensbenz I use solidworks, so I like that HSM plugs right into SW
[04:28:32] <bensbenz> yea, its understandable, a lot of people perfer SW
[04:28:34] <os1r1s> It makes it much easier than the import/export fiasco. And I'm not a fan of the autocad based modeling
[04:29:17] <bensbenz> yeah i guess it depends what you do, when i was younger i could not afford things like SW so i used things like google sketchup
[04:29:34] <bensbenz> fusion reminds me a lot of sketchup, it was an easy jump for me
[04:29:49] <pink_vampire> I want to start do 3d machining.
[04:30:09] <pink_vampire> and solisworks is very limited for that.
[04:30:16] <pink_vampire> solid*
[04:30:17] <bensbenz> the 3d paths are really cool, even for things that are 2d
[04:30:22] <os1r1s> pink_vampire Not sure how that is ...
[04:30:28] <os1r1s> pink_vampire Works pretty well for 3d stuff
[04:30:47] <bensbenz> for example 3d adaptive roughing i can usually rough a part with a single op, instead of multiple 2d ops
[04:31:21] <os1r1s> bensbenz I agree. Your videos are almost an advertisemnt for it :P

[04:32:15] <bensbenz> os1r1s yeah they pretty much are, i probably sound like a fan boy, but i really love it.
[04:32:39] <os1r1s> bensbenz Is your lathe the one without the variable speed?
[04:33:04] <bensbenz> no i have it all working now, I have a vfd on it
[04:33:22] <bensbenz> its still a kinda sucky lathe, needs way more power
[04:33:37] <os1r1s> Would the g0752 have been a faster route?
[04:33:45] <bensbenz> i often have to swap the belts even with the vfd when working on parts over 3" dia
[04:34:02] <bensbenz> probably, but i got this lathe for a steal
[04:34:14] <bensbenz> it was already mostly converted minus the VFD

[07:40:18] <pink_vampire> renesis: inside the probe there is spider that seat on 3 pairs of balls
[07:42:13] <archivist> because the mount finds the one and only possible position its accuracy is less important
[07:44:15] <pink_vampire> but in my case I'm use it in the spindle, not fixed to the machine.
[07:45:23] <pink_vampire> this is why I had to calibrate it, to remove the runout,
[07:46:49] <pink_vampire> archivist: ^
[07:47:11] <archivist> this is what a calibration move should be to check effective ball diameter

[07:53:45] <pink_vampire> I use sharpie marker on the ball, and rotate the probe in the spindle, than I gently touch it with the side of 123 block,
[07:55:05] <archivist> that test in the video checks a standard ball to check the probe
[07:56:24] <pink_vampire> at the beginning just short line come off, and I use the set screws to compensate until I got perfect line on the sharpie
[07:57:25] <pink_vampire> now I want it to be wireless.
[07:59:30] <toastyde1th> to make something have minimal runout is fairly easy, esp if you're trying to mount a ball standard
[08:00:05] <toastyde1th> spin the thing in the spindle slowly, like 30-60 rpm, and attach a dremel to your table with an appropriately tiny grinding bit
[08:00:17] <toastyde1th> grind a cone into the rod
[08:00:28] <toastyde1th> the cone will run concentric as your bearings allow, and then you just use epoxy
[08:01:19] <pink_vampire> I solder the ball to the tip
[08:01:31] -!- Deejay [Deejay!~Deejay@unaffiliated/dj9dj] has joined #linuxcnc
[08:01:44] <Deejay> moin
[08:01:45] <toastyde1th> whatever attachment method you use is fine as long as it doesn't induce creep, and solder is sufficiently low temperature that it shouldn't
[08:02:03] <toastyde1th> would still suggest doing 4-point ball calibration rather than using 123 blocks
[08:02:39] <toastyde1th> the 4 point check will absolutely locate the center of your probe with minimal operator error
[08:03:21] <pink_vampire> you have an idea how to make it wireless?
[08:03:54] <toastyde1th> lots of probes use an IR or induction coil
[08:04:06] <toastyde1th> i've never had to build an entire probe so I don't have any good suggestions there
[08:04:55] <toastyde1th> the ones i've handled (a limited number) used an IR transmitter that only turned on when the probe was unseated
[08:04:57] <pink_vampire> what about rf?
[08:05:02] <toastyde1th> could do that too
[08:05:17] <toastyde1th> in practice, from what I understand, IR is more reliable and accurate
[08:05:20] <toastyde1th> because of noise
[08:05:28] <archivist> 433mhz tx and rx are cheap
[08:05:38] <pink_vampire> I need something reliable and realtime.
[08:05:54] <toastyde1th> IR is pretty realtime, considering it's basically just an optocoupler at that point
[08:06:14] <toastyde1th> battery to probe switch, switch to IR, back around to the battery
[08:06:38] <toastyde1th> there's no debounce, the reciever latches as soon as it sees the first edge
[08:06:59] <pink_vampire> how I can calculate the top speed?
[08:07:07] <toastyde1th> ...top speed?
[08:07:23] <pink_vampire> I mean. how much realtime..
[08:07:41] <toastyde1th> measure the response of the IR tx/rx
[08:07:49] <toastyde1th> but since they're often over 500 khz...
[08:08:18] <toastyde1th> the practical limit is the logic on the spindle side, not the optocoupler
[08:09:13] <pink_vampire> and how I prevent noise?
[08:09:19] <toastyde1th> noise?
[08:09:35] <pink_vampire> false reading
[08:09:38] <toastyde1th> there's not a ton of sources of noise for an optocoupler
[08:09:45] <toastyde1th> esp if you're using a fairly bright IR LED
[08:09:56] <toastyde1th> you can set the threshhold on the spindle side

[08:10:48] <toastyde1th> it's not like you're looking at this thing when the probe isn't in place
[08:10:54] <pink_vampire> but IR can be blocked.
[08:11:12] <pink_vampire> dust, chips, oil..
[08:11:14] <toastyde1th> in practice it isn't, this isn't some tiny sensor
[08:11:37] <toastyde1th> it's best if the sensor gets hit by oil, because bigass crusty chips are really the only thing that gets in the way
[08:11:43] <toastyde1th> oil or coolant
[08:12:56] <toastyde1th> but if you're very worried about it, use another method
[08:13:01] <pink_vampire> there is a way to encode the RF signal.
[08:13:06] <toastyde1th> IR is just very simple to implement and fairly straightforward
[08:13:46] <toastyde1th> there is *lots* of RF noise so that becomes necessarily more complex
[08:13:49] <pink_vampire> I don't want simple, I want right,
[08:13:59] <toastyde1th> simple is often right
[08:14:09] <toastyde1th> there's a reason 30k probes use IR
[08:14:29] <toastyde1th> you can use RF or induction as well
[08:14:47] <pink_vampire> and I dont have eye contact from the panel to the machine...
[08:14:55] <toastyde1th> wat
[08:15:03] <pink_vampire> how the induction work?
[08:15:10] <toastyde1th> all the methods i'm aware of involve mounting the reciever ON the spindle
[08:15:23] <toastyde1th> so you have like 2-3mm between the tx and rx
[08:15:30] <archivist> near spindle not on
[08:15:38] -!- vapula [vapula!~rolland@195.25.189.2] has joined #linuxcnc
[08:15:43] <archivist> on the headstock
[08:15:46] <toastyde1th> the housing, sorry
[08:15:51] <toastyde1th> don't put the reciever on anything that rotates
[08:16:22] <toastyde1th> induction works similarly to IR
[08:16:25] <pink_vampire> what about wifi or bluetooth module?
[08:16:34] <toastyde1th> you have two coils instead of an optocoupler
[08:16:38] <archivist> wired is ok because the spindle is not rotating during probing
[08:16:52] <toastyde1th> you could do that but nobody really does
[08:16:58] <pink_vampire> wire is mess
[08:17:00] <toastyde1th> because it's a much larger battery drain that only-on
[08:17:07] <toastyde1th> *versus only-on when probing
[08:17:43] <toastyde1th> if you check the battery frequently it would work in a home shop, but in a production environment you'd wind up crashing the tool because some dumbass would forget
[08:17:47] <pink_vampire> I can make charging cradle for it.
[08:18:07] <toastyde1th> it is easier for me to just include "change the battery every 6 months" as part of preventative maintainance
[08:18:30] <archivist> the renishaw wakes up the probe and knows its battery state
[08:18:52] <toastyde1th> yeah, good probes will but not all probes do
[08:19:14] <pink_vampire> or to use inverted logic
[08:19:34] <toastyde1th> but even so I've had operators ignore all kinds of machine warnings, it just seems to be The Thing To Do
[08:19:42] <toastyde1th> not super applicable for a home shop obviously
[08:19:55] <archivist> operators are lazy shitz
[08:20:26] <Jymmm> Work smarter, not harder
[08:21:03] <toastyde1th> using induction obviously alleviates all those problems entirely
[08:21:12] <toastyde1th> but that's more sensitive to shit in the way
[08:21:19] <archivist> lazy is avoiding thinking in an operator
[08:22:15] <toastyde1th> i'd still prefer a 6month battery rotation and a dumb probe, it is less things to fuck up
[08:22:34] <pink_vampire> what about celular modem?
[08:22:47] <archivist> too expensive and silly
[08:22:51] <toastyde1th> well if your probe needs to check facebook
[08:23:02] <pink_vampire> and not real time..
[08:23:12] <pink_vampire> It'a very cheap
[08:23:27] <archivist> too many wifi drop outs useless
[08:23:30] <toastyde1th> seriously, induction and IR are the most reliable ways
[08:23:38] <toastyde1th> followed very closely by RF
[08:23:59] <archivist> or real wire, how my cmm does it
[08:24:10] <toastyde1th> the most important thing in a probe is repeatability, which means low lag
[08:24:14] <Jymmm> toastyde1th: Re: "...operators ignore all kinds of machine warnings" you just have the wrong warnings is all.... "You are about to fuck up everything, are you sure?"
[08:24:21] <toastyde1th> hahahahaha
[08:24:37] <toastyde1th> i once had a guy watch a drill fall out of the machine
[08:24:39] <toastyde1th> it even halted
[08:24:45] <toastyde1th> "oops i let go of the tool? pls hlp?"
[08:24:55] <toastyde1th> dude just hit go
[08:25:00] <toastyde1th> kapow
[08:25:00] <archivist> if they get repeated wornings they lose sense of what warning are about
[08:25:35] <pink_vampire> I cant use just transmitter and receiver, I need something that make a link with feedback, this way I will know if there is battery issue
[08:25:46] <toastyde1th> then use induction
[08:25:50] <toastyde1th> so you can power the thing
[08:26:05] <toastyde1th> you can send signal as well as power over the same coil
[08:26:08] <archivist> the sender sends two signals, battery level and the contact info
[08:26:13] <Jymmm> Eh, M$ mentality. You need to make it hard to continue... "To continue, what is 42/34 *3", you have 7 seconds..."

[10:46:28] <XXCoder> yeah
[10:46:31] <Frank__> sorry, not anything
[10:46:32] <XXCoder> open HAL maker
[10:46:32] <Frank__> nothing
[10:46:33] <Frank__> lol
[10:46:45] <XXCoder> umm forgot what name it is
[10:46:52] <XXCoder> look for config in menu
[10:47:04] <XXCoder> make sure not to select umm mena something one
[10:47:06] <archivist> use an editor
[10:47:33] <XXCoder> unless your card is mesa
[10:47:38] <Frank__> yes
[10:47:44] <Frank__> its mesa
[10:47:56] <XXCoder> then use mesa configuration maker
[10:48:33] <archivist> are you guessing its name?
[10:48:45] <XXCoder> initally yes, now no
[10:48:46] <Frank__> that just does the trick? cuz i've been reading post from like 2013 where they have the same setup but they had to make the files
[10:49:17] <XXCoder> Frank__: not sure, but making config helps you have a file to edit
[10:49:30] <Frank__> im using 5i25+7i85+7i84
[10:49:47] <Frank__> okey
[10:49:48] <archivist> its actually called pncconf

[11:02:52] <pink_vampire> first thing I look at mitutoyo
[11:03:04] <XXCoder> I love my mitytoyo caliper
[11:03:16] <XXCoder> for home I have crappy chinese one
[11:03:18] <pink_vampire> but I can't find anything with fractions
[11:03:29] <archivist> I have two mitutoyo, the cheap ones power down just when you dont want that
[11:03:48] <XXCoder> no caliper has fractions from what I understand
[11:03:56] <XXCoder> just inches or mm, in decimal form
[11:04:09] <pink_vampire> the new ones have
[11:04:15] <XXCoder> interesting
[11:04:37] <pink_vampire> I think to go with this one
[11:04:39] <pink_vampire> http://www.amazon.com/iGaging-ABSOLUTE-Digital-Electronic-Caliper/dp/B00INL0BTS/ref=sr_1_2?s=hi&ie=UTF8&qid=1451387032&sr=1-2&keywords=iGaging
[11:04:40] <XXCoder> archivist: my el cheapo one powers down at around same length time as my good one
[11:04:59] <archivist> mitutoyu dont power down
[11:05:04] <XXCoder> but oddly, cheapo has way to turn off when done, while expensive one dont
[11:05:33] <XXCoder> sure it does, display turns off.
[11:05:47] <archivist> mine does not turn off the display
[11:05:59] <archivist> unless I power it off
[11:06:13] <pink_vampire> this one has absolute zero
[11:07:04] <pink_vampire> and it also has the option for usb readout
[11:07:12] <pink_vampire> http://www.amazon.com/iGaging-SPC-Cable-OriginCal-100-700/dp/B00INL0BA2/ref=sr_1_1?s=hi&ie=UTF8&qid=1451387203&sr=1-1&keywords=B00INL0BA2
[11:07:50] <pink_vampire> forme the usb readout is very niec feature
[11:07:58] <pink_vampire> for me*
[11:08:17] <archivist> I have tested the cheapo calipers, all seem to measure down to .001
[11:08:20] <XXCoder> dunno how good that brand is but cool I guess as its half price my expensive one
[11:08:44] <XXCoder> archivist: mine can do .0005 but I only trust it to get around .0015 precision which isnt very good
[11:09:19] <archivist> usually id is adjustment needs looking at if worse
[11:09:23] <archivist> it
[11:12:41] <XXCoder> I guess so but since it randomly gets .001 +- when powered on it dont matter
[11:12:51] <XXCoder> I just zero it out each use
[11:14:05] <pink_vampire> XXCoder: you have the mitutoyo?
[11:14:25] <XXCoder> yep caliper, micrometer and one of dial
[11:14:29] <XXCoder> indictor
[11:14:40] <pink_vampire> carabide?
[11:14:44] <XXCoder> "big 3" in my toolset, as I use em pretty often
[11:15:29] <XXCoder> carabide?
[11:16:22] <pink_vampire> made from carbide
[11:16:32] <XXCoder> oh hmm dunno
[11:16:42] <enleth> fun fact: mitutoyo calipers don't actually turn off
[11:16:51] <XXCoder> just display eh
[11:16:57] <enleth> yeah
[11:17:20] <XXCoder> interesting as it took mine 8 months to run out of juice
[11:17:31] <enleth> AvE did a fun test of a counterfeit mitutoyo some time ago
[11:18:11] <enleth> the chinese were qiite attentive to detail and their knockoff did stay on all the time as well, just like the original
[11:18:29] <enleth> but they didn't get it right
[11:18:34] <XXCoder> probably firmware clone? ahh
[11:18:52] <archivist> has to stay on for the absolute to work
[11:18:58] <enleth> and it drained batteries real fast even with display off
[11:19:51] <archivist> I get many months from each battery
[11:20:13] <enleth> but it didn't have BDO, so it made shitty readinga when low on juice with no warning
[11:20:33] <XXCoder> my el cheapo (its orginial battery even) lasted a year, but then I didnt use it often most months
[11:20:35] <pink_vampire> also I need to get nice and solid compass
[11:21:04] <enleth> XXCoder: but was it the kind that maintains position?
[11:21:22] <XXCoder> enleth: maybe or maybe not, its so shitty I cant tell
[11:21:30] <ReadError> the igaging calipers I have are very nice
[11:21:36] <XXCoder> I have to zero it out each dang use
[11:22:02] <pink_vampire> ReadError: you use the usb?
[11:22:12] <ReadError> pink_vampire nah have not got that adapter yet
[11:22:20] <XXCoder> its fine for what I plan to use it for though as I only need .01 precision.
[11:22:47] <enleth> well the trick is with firmware - all modern uCs have sleep states and BDO but you have to actively enable and support them in the code
[11:24:43] <enleth> the AvE's mitutoyo knockoff was actually decent when it comes to measurements but utterly useless within two weeks of battery replacement
[11:25:18] <ReadError> the igaging stay on
[11:25:24] <ReadError> but even after leaving it on for a few days
[11:25:28] <ReadError> battery is still original
[11:25:39] <XXCoder> few days is nothing really
[11:25:42] <ReadError> good build quality, seem solid
[11:25:44] <XXCoder> mine lasted 8 months
[11:26:10] <pink_vampire> on my lost caliper I add external battary.
[11:26:23] <pink_vampire> and it last for years.
[11:26:25] <XXCoder> some days at work i use it like I need it to live (around 3 per minute for 10 hours)
[11:26:30] <pink_vampire> one AA
[11:26:40] <XXCoder> dang
[11:26:50] <XXCoder> you cant do that and preserve coolant-proofness
[11:26:54] <XXCoder> mine is coolant proof
[11:27:32] <pink_vampire> put the battery in test tube..
[11:27:44] <pink_vampire> and use AAA

[11:54:19] <pink_vampire> class D laser.. no cover...
[11:54:46] <pink_vampire> natural selection?
[11:55:09] <pink_vampire> XXCoder: ?
[11:55:21] <XXCoder> laser glasses
[11:55:27] <XXCoder> thats definitely a requirement
[11:55:34] <XXCoder> and laser warning on door
[11:55:48] <enleth> XXCoder: glasses that actually work cost 2x the price of this contraption
[11:56:20] <XXCoder> its vastly cheaper to just attach laser to my cnc router
[11:56:44] <XXCoder> or free if I just use my laser pointer lol (no cut/mark though)
[11:56:48] <pink_vampire> enleth: any recommendation?
[11:57:56] <enleth> pink_vampire: just google it, if they give specific frequency ranges and power/exposure ratings, and it's expensive, it will protect you
[11:58:27] <enleth> just don't buy chinese laser glasses
[11:58:40] <pink_vampire> that for sure!
[11:59:47] <XXCoder> I would just cover machine really lol
[12:00:09] <enleth> I've got a 40W CO2 laser cutter and the proper glasses cost almost half the price of the cutter
[12:00:39] <pink_vampire> what brand?
[12:01:35] <enleth> don't remember now, but that was a first google hit and they're made in the US
[12:01:43] <Wolf_> weird, isn’t regular old poly carb opaque to CO2 lasers?
[12:02:45] <enleth> Wolf_: if it's opaque, it will absorb the beam. the trick is making the glasses survive long enough for you to notice and move away/hit the estop

[12:06:53] <pink_vampire> excimer laser..
[12:06:58] <pink_vampire> soo cool
[12:07:38] <enleth> if you want to cut things, you will most likely use a CO2 tube laser
[12:07:44] <pink_vampire> it makethe smallest dot
[12:08:00] <Wolf_> most affordable
[12:08:08] <enleth> chinese ones are OK-ish
[12:08:24] <enleth> just replace the controls first thing after getting one
[12:08:26] <Wolf_> for wattage/size/input requirements anyways
[12:08:32] <pink_vampire> excimer is uv laser co2 is IR laser
[12:08:59] <XXCoder> I read a project site where guy made a co2 laser
[12:09:00] <enleth> the tube is fine, mechanicals are acceptable, electronics is shit
[12:09:03] <XXCoder> pretty awesome
[12:09:09] <pink_vampire> the point that you can make with excimer much smaller than co2

[14:27:50] <cat_lady> Hello guys. Sorry if this question is documented somewhere, but I did and extensive research, and the only thing I was able to find was:
[14:28:02] <cat_lady> ...
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNC_Supported_Hardware
[14:28:08] <cat_lady> ...which seems severely outdated
[14:28:49] <cat_lady> ...so, the question is - what hardware is known to work well for software step generation, and somehow obtainable nowadays? or is there a list somewhere?
[14:29:46] <archivist> most of us using steppers grab a few old PCs and try the latency test on them
[14:29:47] <cat_lady> I'm thinking mainly about motherboards and CPU combinations. I tried thinkpad R51 notebooks due to thinkpads having good reputation for linuxCNC and parallel port, but it was performing infernal as stepgen due to realtime problems (at least amongst terrible reputation notebooks)
[14:30:19] <cat_lady> I see. Well, I'm in position where I used one old Pc for machine, and I'm building another one, without spare PC's to try - I need to purchase something, probably used.
[14:30:36] <archivist> if the latency test is below 25000 jitter it may be usable
[14:31:44] <cncbasher> is their any known limit that jitter is required to be below ?
[14:33:05] <archivist> you just have to slow your steppers down to suit
[14:33:42] <archivist> but some boards and video combinations are terrible

[14:41:57] <archivist> JT-Shop, got the logging working
[14:42:12] <JT-Shop> was it broke?
[14:42:40] <archivist> the way it opens early I would call that broken
[14:44:50] <archivist> code ended up as
http://www.archivist.info/cnc/wormtest/wormtest.ngc
[14:45:44] <JT-Shop> oh the logging
[14:46:11] <archivist> with some fiddles in hal connect encoders to motion.analog-in
[14:46:30] <JT-Shop> so the m66 breaks the code up so it won't log until it runs?
[14:47:33] <archivist> no idea what does what and why it waits only when you use the right variables/gcodes

[14:49:18] <cat_lady> than k you guys, i will search the forum. If you have any link to thread (that I could miss, aka not easily visible), I will be glad for it, too :)
[14:49:39] <cat_lady> the first machine I'm using got around 5k jitter in worst case, so it got lucky, as it was random old PC

[14:50:27] <archivist> that is as good as the best PC I have, an old Compaq
[14:50:31] <cat_lady> trying to purchase something specifically for CNC was much less lucky, though - for example, said R51 thinkpad got like 2k jitter all the time, EXCEPT that it jumps to 2 000 000 (!) from time to time, and I eliminated any power-saving in terferring possibility
[14:50:43] <cat_lady> which of course invalidates its use as stepgen
[14:51:40] <JT-Shop> you don't use pads and laptops for CNC
[14:51:45] <JT-Shop> as you found out
[14:51:48] <cat_lady> yes :)
[14:52:11] <cat_lady> I was aware of that - just got a little missguided by people claiming that thinkpads with parallel port are exceptions here, at elast old ones. Was wrong, as it turned out

[15:11:16] <CaptHindsight> Intel and M$ posted one thing but did whatever they wanted with it
[15:14:10] <cat_lady> yea... i tried disabling SMI, and it *seemed* to be disabled, but spikes prevailed. They were not even recurring at set time intervals, it was seemingly random. I guess it is still something deep about power saving

[15:15:22] <cat_lady> anyway, at this moment I'm just inclined to buy desktop PC. the problem is that going through list from wiki, almost every unit there is virtually unobtainable, except from buying on e-bay from far away and paying 3x the cost of unit itself in shipping
[15:15:47] <CaptHindsight> since the EC can operate out of band even killing SMI won't help
[15:15:56] <cat_lady> I see.
[15:17:16] <archivist> look on the local ebay/freecycle/cheap for PCs
[15:18:05] <CaptHindsight> more recent laptops and PC's have 2-3 operating systems in the firmware that operate out-of-band that operate securely from you that can also interrupt real time

[15:34:41] <DIYtryin_> am i missing something?
[15:34:56] <CaptHindsight> DIYtryin_: it's supported outside of linuxcnc, very few use it here but you'll find more info on the forums
[15:35:38] <CaptHindsight> DIYtryin_: motion is over LPT, non-real time is over hal2arduino
[15:35:53] <DIYtryin_> let me google lpt for a sec
[15:36:05] <CaptHindsight> lpt = parallel port
[15:36:33] <Frank__> capthindsight, do u happen to know if mesa ships to south america?
[15:37:11] <DIYtryin_> ty. So the thing is.. lpt is already in use and I've been asked to create a usb connection
[15:37:14] <CaptHindsight> most here use a FPGA card for motion with it's extra IO for GPIO rather than add a *duino over USB
[15:37:23] <CaptHindsight> it's/its

[15:43:42] <DIYtryin_> i/o is fine

[16:01:37] <CaptHindsight> DIYtryin_: try contacting its developer
[16:03:31] <DIYtryin_> I'll do that right now
[16:04:03] <CaptHindsight> its a project outside of Linuxcnc and he was a student
[16:04:25] <CaptHindsight> so you're pretty much on your own
[16:06:50] <DIYtryin_> I'm afraid so.. But just to be clear: Pretty much nobody here has interacted with a python script trough pyvcp?
[16:07:11] <DIYtryin_> Or is that to a not clear question;)

[16:18:00] -!- b_b has quit [Remote host closed the connection]
[16:18:10] <bensbenz> Roguish, what I was looking for was to hit home and then have the X DRO read say 5.889 which is the exact distance between centerline of the lathe and my tool 1.
[16:18:11] <Roguish> it's in the 'home' and 'homeoffset' and where ever the home switch is.
[16:19:02] <bensbenz> right now the machine homes just fine, but then its at 0 absolute
[16:19:06] amnesic is now known as amnesic_away
[16:19:11] <Roguish> they are static in the setup. not changeble with tools.
[16:19:50] <bensbenz> Ok thats fine, but can I change the position the machine thinks its at after homing?
[16:21:04] <Roguish> sounds like you need offsets, like G54. I don't do lathes so not sure how it would work, but probably same as in mills.
[16:21:40] <Roguish> http://linuxcnc.org/docs/2.7/html/gcode/coordinates.html

[16:26:32] <Roguish> bensbenz: offsets aren't difficult, once you get used to them.
[16:30:32] <bensbenz> probably not, just another thing to remember. my old way was pretty darn simple for lathe work, never had to touch off parts, just home and off you go.
[16:31:59] <JT-Shop> works ok if you only have one tool
[16:32:10] <cradek> offsets are persistent, so once you set it, it's there forever
[16:34:48] <bensbenz> JT-Shop, no I use it for all my tools. tool 1 references my exact location relative to the spindle
[16:34:59] <bensbenz> all other tools reference from that master tool
[16:35:08] <bensbenz> works awesome on the old control
[16:36:39] <bensbenz> sounds like I just need to set that info in an offset to make it work as apposed to just changing the machine DRO like I used to

[18:05:26] <CaptHindsight> andypugh: good deal
[18:05:35] <andypugh> (err, actually, and another one, not shown, but it was small and flat)
[18:06:22] <maxcnc> irontree9: how is it with g-code generations
[18:06:56] <Frank__> noob question, my hiwin 25mm guides are supposed to go on a 2.4mts 8foot machined surface, im afraid of the place where i send it to get machined, the manual doesnt mention straightness tolerance, just parallelism and elevation-deviation tolerances, and they are running on old planners, some 6 mts and others 3 mts long, do you think i will be in trouble?
[18:07:37] <maxcnc> no there are good
[18:07:47] <archivist> you can hand scrape to perfection after if you want
[18:07:58] <maxcnc> Frank__: you can bent them to a curve or straiten them
[18:08:08] <Frank__> even if they are 1200mm appart between the 2?
[18:08:10] <andypugh> Planers are the best machines ever for making things flat.
[18:08:22] <Frank__> yes, i guess i can adjust it somewhat
[18:08:28] <Frank__> i dont need perfection, im routing wood
[18:08:38] <maxcnc> i ise a 80x15mm on the high side to get them straight
[18:08:39] <CaptHindsight> andypugh: I can SLA patterns and molds that are water soluble after curing. I should make something similar and smaller as a demo
[18:08:42] <Frank__> but i just want it to work good enough for them to be durable
[18:08:55] <archivist> wood, you will have perfection already :)
[18:09:07] <maxcnc> Frank__: No Problem on them trust me
[18:09:07] <Frank__> u are the best guys, cheering me up on my bad days !
[18:09:18] <Frank__> im 22 and its my first build
[18:09:21] <Frank__> lol
[18:09:32] <andypugh> Frank__: If they are being machined on an old planer I would fully expect them to be the flattest thing you own :-)
[18:09:39] <Frank__> i already have in mind like 3 other builds with linux
[18:09:39] <archivist> a youngster
[18:10:36] <maxcnc> Frank__: you are in the Us if i remember correct
[18:10:39] <Frank__> awesome, shame u cant see me smiling, hahaha
[18:11:08] <Frank__> no im not,
[18:11:17] <maxcnc> Europ
[18:11:38] <Frank__> i'd like to, here things are not made with quality in mind

[18:12:46] <Frank__> i already bought them!

[18:14:29] <maxcnc> Frank__: im still using cheep steppers on that size with 0.05mm Precision at 4000mm/min speed
[18:14:42] <Frank__> 2 servos 1 kw, and gantry around 130-150kg
[18:15:34] <Frank__> look, do you think i should make them change me the motor? it came with a little bump on the box, or am i beeing to picky?
http://imgur.com/Pwawx8g
[18:16:02] <maxcnc> NP
[18:16:05] <Frank__> wow
[18:16:22] <Frank__> 0.05mm is niiiiiice
[18:16:27] <archivist> not even a scratch
[18:16:31] <Frank__> at least for wood
[18:16:33] <maxcnc> they are good packed inside and can take some bumping
[18:17:01] <maxcnc> go for it with mesa
[18:17:10] <maxcnc> get a good gearing
[18:17:18] <Frank__> yes, 5i25 + 7i85s + 7i74?
[18:17:33] <Frank__> i was wondering if he ships to south america,,
[18:17:45] <maxcnc> i only use 7i76 e as for steppers
[18:18:38] <archivist> Frank__, ask pcw_home
[18:19:14] <Frank__> i query pcw, i guess hes not around right now, should i bother pcw_home too?
[18:19:55] <maxcnc> Frank__: what is the price on one motor
[18:20:23] <Frank__> here its more expensive than in the us because of taxes
[18:20:30] <Frank__> i paid them 1000usd
[18:20:34] <Frank__> 1 piece
[18:20:38] <Frank__> x4
[18:21:06] <Frank__> but i assume they should be around 500usd
[18:21:26] amnesic is now known as amnesic_away
[18:21:33] <Frank__> its the economic line of panasonic servos
[18:21:34] <maxcnc> hits me from the chair my 500kg router has lower price electronics on the hole mashine
[18:22:29] <Frank__> yes, i should have taken a trip to the us and bring them myself haha
[18:22:54] <maxcnc> i got 3Nm Stepeprs at 72V on 30:1 gear
[18:23:16] <maxcnc> you can not stop this X Y axis by hand
[18:23:31] <Frank__> i am guessing mechanic gearing right?
[18:23:33] <maxcnc> tried it with a friend on 100mm/min

[18:23:49] <Frank__> on a wood router?
[18:23:53] <Frank__> boy
[18:24:11] <maxcnc> the router has multiple functions
[18:24:17] <Frank__> do u have a pic of that steel?
[18:24:20] <maxcnc> its on 0.01mm
[18:24:39] <Frank__> it should do aluminium like a breeze
[18:25:03] <Frank__> excuse my english :D
[18:25:10] <maxcnc> yes it does in full under water cut
[18:26:04] <Frank__> im going with belts for the gearing if i got the name right
[18:26:31] <maxcnc> timing belts on servo 3000U is not a good idee
[18:27:16] <Frank__> flex?

[18:27:59] <archivist> just get a large enough belt for the job
[18:28:03] <maxcnc> thinks like that or plenetary front gears
[18:28:11] <maxcnc> planetary
[18:28:47] <maxcnc> no backlash and force in mass
[18:29:16] <Frank__> u are on ballscrews?
[18:29:19] <archivist> planetary has backlash
[18:29:28] <maxcnc> Frank__: you may find this distribiutor also in the SouthAmerica region
[18:29:37] <Frank__> im going with rack & pinion,
[18:29:51] <maxcnc> im also on rack and pinion
[18:30:19] <maxcnc> im using Metric ones that fit perfect the 400steps stepeprs
[18:30:26] <Frank__> yes, but im a little low on cash right now, i think u understand after 4000usd in motors haha
[18:30:28] -!- almostworking has quit [Quit: Textual IRC Client: www.textualapp.com]
[18:30:58] <maxcnc> you woudt be lower thewn 500 on Stepeprs with same outcome
[18:31:30] <Frank__> actually, i bought from the motor dealer an adtech controller too, but i plan on changing it for the 2 extra motors that i am needing, they are almost the same price without the cables, so..
[18:31:44] <Frank__> i mean, i bought the drivers too... the pack is 1000usd
[18:31:57] <maxcnc> if plan futhure projects try on stepeprs you might be impressed
[18:32:12] <Frank__> yes,
[18:32:18] <Frank__> i messed up a little
[18:32:44] <maxcnc> https://www.pro-tos.de/shop/ thats whut i use
[18:32:49] <Frank__> as u might have noticed i was/am a little insecure about the hole build, and tryed to overbuild it
[18:34:05] <maxcnc> you getting the horse from the wrong side
[18:34:12] <Frank__> and right now mixing 2 servo with 2 stepper seems like a waste right?
[18:34:23] <maxcnc> stay low cost make big money
[18:34:43] <Frank__> sometimes i think i should have made a mechmate or the kind
[18:35:26] <Frank__> but, at least this setup is going to last...
[18:35:27] <maxcnc> i got a 3USD L297 router here that makes 200USD a month
[18:35:57] <Frank__> build it once and forget
[18:36:21] <maxcnc> <- hopes for you that ypou will be right on that
[18:36:34] <Frank__> hahaha
[18:36:37] <Frank__> i must..
[18:36:42] <Frank__> but anyway.. im 22
[18:37:09] <Frank__> i shouldnt be that hard with myself
[18:37:28] <maxcnc> it will get to the best you ever designed
[18:38:03] <maxcnc> and makes you a near money man
[18:38:17] <maxcnc> no im out of english

[18:39:41] <CaptHindsight> anyone know the difference between heating (a furnace for a foundry) with LP vs natural gas prices this year?
[18:40:23] <maxcnc> LP liquid petrol ?
[18:40:43] <CaptHindsight> LP = liquid propane
[18:40:55] <maxcnc> LNG did not got the price differences to the coustemer

[20:25:20] <bensbenz> newb question here, with AXIS why does tool touch off mess with X if I have Z selected? shouldnt it just modify for Z?
[20:25:53] <CaptHindsight> if I combine a furnace with a BBQ I wouldn't mind using it outdoors as much
[20:26:03] <neverbuya_subaru> kvirc i like
[20:26:30] <Tom_itx> yeah well you like subaru too
[20:26:43] <bensbenz> _methods: in chicago if you want to pay the tolls you can use necco wafer candies
[20:26:49] <_methods> hahahah
[20:27:08] <neverbuya_subaru> haha tom
[20:27:08] <neverbuya_subaru> :)
[20:27:16] <Tom_itx> it would be interesting to see a list of things pulled from a toll basket
[20:27:27] <_methods> i was glad that chzbrgr was there because i was heading to the airport and i didnt have any cash on me
[20:27:29] <bensbenz> _methods: just slide them in though, so they dont break
[20:27:35] <neverbuya_subaru> bensbenz: user error
[20:27:51] <_methods> so i just pretended to throw it in and drove off
[20:27:54] <CaptHindsight> Tom_itx: since they have 17 cameras at each basket probably not much
[20:28:00] <bensbenz> neverbuya_subaru: no doubt what am i doing wrong?
[20:28:10] <neverbuya_subaru> need to select the axis before hitting tool touch off
[20:28:17] -!- jesseg [jesseg!~jesseg@64.146.180.237] has parted #linuxcnc
[20:28:22] <neverbuya_subaru> if you press left or right key for example
[20:28:26] <neverbuya_subaru> itll select the X axis
[20:28:29] <neverbuya_subaru> automatically
[20:28:41] <neverbuya_subaru> so you gotta make sure you are clicking the z axis keys only before hitting tool touch off
[20:28:42] <bensbenz> neverbuya_subaru: ah maybe thats it... let me try
[20:28:42] <CaptHindsight> I heard that some slugs work just as well
[20:29:01] <bensbenz> neverbuya_subaru: well i thought i was clicking the radio button for z
[20:29:12] <neverbuya_subaru> yea but if you press left right
[20:29:15] <neverbuya_subaru> itll go to x
[20:29:21] <neverbuya_subaru> that played games with me for a little while :P
[20:29:28] <bensbenz> neverbuya_subaru: i hear ya, trying now

[20:35:44] <neverbuya_subaru> bensbenz: to be fair i think its okay that it functions like that
[20:35:56] <neverbuya_subaru> because usally you move one axis only
[20:35:59] <neverbuya_subaru> when touching off
[20:39:05] <bensbenz> neverbuya_subaru: just something good to know, i was going nuts thinking im doing something wrong, and well i was but i didnt know it lol
[20:41:41] -!- Tom_L has quit [Quit: Leaving]
[20:45:18] <bensbenz> ok next newb question, i call t16 m6 but I dont see any change in the DRO, i get the prompt for the tool change and hit continue but it doesnt show the tools offsets. what am i doing wrong there?
[20:45:44] <neverbuya_subaru> t16 m6 g43
[20:45:55] <neverbuya_subaru> you gotta call the g43 to update the tool height
[20:46:10] <neverbuya_subaru> when you do g43 by itself, it picks up the tool table offsets for tool 16
[20:46:26] <neverbuya_subaru> but you could also have an offet at say tool 700
[20:46:38] <neverbuya_subaru> and go t16 m6 g43 h700 and pick up the offsets from tool 700
[20:46:57] <bensbenz> ok so thats the same with the lathe then?
[20:47:00] <neverbuya_subaru> yes
[20:47:16] <bensbenz> ok good to know, so my cam post needs to do that too as well I assume?
[20:47:22] <neverbuya_subaru> yes
[20:47:23] <neverbuya_subaru> always
[20:47:31] <XXCoder> dont you also need h16
[20:47:32] <CaptHindsight> t12: whatever became of the DNA laser printer lab?
[20:47:35] <neverbuya_subaru> no XXCoder
[20:47:37] <XXCoder> so it knows what height to use
[20:47:43] <neverbuya_subaru> by default it picks up the register that matches w/ your tool
[20:47:50] <XXCoder> cool
[20:48:11] <neverbuya_subaru> i used to type the tool offset number
[20:48:13] <neverbuya_subaru> but i dont do it anymore
[20:48:19] <bensbenz> neverbuya_subaru: awesome that works
[20:48:21] <neverbuya_subaru> because it's so easy to forget to change it, and change the tool number only
[20:48:32] <neverbuya_subaru> thats the only time ive had a serious end mill crash
[20:48:37] <neverbuya_subaru> 1/4" end mill broke like a tooth pick
[20:48:38] <neverbuya_subaru> :)
[20:50:56] <bensbenz> so when your bouncing between tools you always add g43, any scenario when that would need to be canceled with G49?

[21:04:34] <neverbuya_subaru> if you did not set the correct height offset
[21:04:37] <neverbuya_subaru> or diameter offset
[21:08:40] <bensbenz> neverbuya_subaru: ok thanks
[21:08:59] <bensbenz> neverbuya_subaru: looking on the forums for a fusion360\hsmworks turn post

[21:47:10] <Frank___> people, i am needing to do holes in 15mm 3/4 in. steel, lots of them, for the rack. is it doable with a power drill?
[21:47:19] <Frank___> or should i rent a magnetic drill
[21:50:33] <_methods> what dia?
[21:50:42] <_methods> and what is lots?
[21:50:44] <Frank___> 5mm
[21:51:07] <Frank___> 55 of them
[21:51:52] <XXCoder> got a drill press?
[21:51:55] <XXCoder> easier with it
[21:52:01] <_methods> well a mag drill would certainly make it much easier
[21:52:02] <XXCoder> assuming part is small enough
[21:52:09] <Frank___> yes, but i cant put the machine under it
[21:52:19] <Frank___> exactly
[21:52:36] <_methods> hand drilling thu 15mm might not be much fun
[21:52:44] <_methods> especially 55x
[21:52:53] <Frank___> 825mm total :(
[21:52:55] <bensbenz> is anyone aware if this would still work:
http://sourceforge.net/p/emc/feature-requests/103/
[21:52:58] <Frank___> of steel
[21:53:42] <Frank___> ye, kind of desnt make sense, i guess i will have to rent one
[21:53:54] <_methods> you don't have a mag drill?
[21:54:00] <Frank___> nope
[21:54:04] <_methods> ouch
[21:54:16] <_methods> life without a mag drill must be horrible
[21:54:21] <Deejay> gn8
[21:54:24] <Frank___> there would be no question then ! :D

[21:55:18] <_methods> get you out of lots of trouble
[21:55:24] <_methods> or into lots of trouble lol
[21:58:07] <_methods> i wonder why no one has ever made a magnetic grinder/cutoff machine
[21:58:10] <Frank___> yes, the machining company couldnt do them, they are on a tricky position for the machine
[21:58:22] <_methods> would be kinda useful for making odd cuts in stuff
[21:58:23] <Frank___> patent asap! haha
[21:58:28] <_methods> yeah
[21:58:39] <_methods> have it so it can make compound cuts
[21:59:12] <Frank___> you mean like ana abrasive saw with mag?
[21:59:16] <_methods> yeah
[22:00:11] <Frank___> any advice for a hammered finger? hah
[22:00:17] <_methods> don't do that?
[22:00:25] <Frank___> i mean after it
[22:00:29] <_methods> hahah
[22:00:33] <Frank___> ur mean
[22:00:36] <_methods> well how bad is it hammered?
[22:00:58] <Frank___> black 3/8 in spot middle finger
[22:01:00] <_methods> you're still typing so i assume it's not life threatening lol
[22:01:15] <_methods> ahh hot nail through your fingernail to relieve pressure
[22:01:15] <Frank___> my finger will fall off (?)
[22:01:23] <Frank___> hahahaha
[22:01:24] <_methods> otherwise your nail might fall off
[22:01:29] <Frank___> lets try that
[22:01:31] <Frank___> brb
[22:01:35] <_methods> or small drill
[22:01:49] <_methods> works best with a pin vise lol
[22:01:49] <Frank___> mag or common?
[22:01:52] <_methods> not a drill
[22:01:52] <Frank___> hahahç
[22:01:57] <_methods> yeah no mag lol
[22:02:27] <_methods> but a hot needle will melt right through your nail
[22:02:34] <_methods> or small nail
[22:02:38] <Frank___> ew
[22:02:51] <Frank___> luckily didnt hit the nail
[22:02:52] <_methods> yeah it stinks
[22:03:12] <_methods> oh you just have a blood blister on your finger
[22:03:28] <_methods> i thought it was under your finger nail
[22:04:14] <Frank___> right on the tip
[22:04:37] <_methods> yeah i'd just pop it with a needle if it's bothering you
[22:04:47] <_methods> but the text book answer is to leave it alone
[22:05:10] <Frank___> thanks doc
[22:05:18] <_methods> heheh

[22:08:07] <Frank___> high speed steel is the best?
[22:08:08] <Tom_itx> then poke it
[22:08:08] <_methods> i just kinda bumble around from project to project until the finish themselves
[22:08:16] <Frank___> hahaah
[22:08:24] <Frank___> u think im gonna choke on it?
[22:08:26] <Tom_itx> _methods what brand drill is yours?
[22:08:34] <_methods> hougen
[22:09:32] <Tom_itx> i've always liked milwaukee stuff
[22:09:41] <Tom_itx> theirs looks quite compact
[22:10:07] <_methods> yeah i like the milwaukees too
[22:10:16] <_methods> but the hougen is a whole diff class
[22:10:38] <_methods> the build quality of the hougen is great
[22:11:09] <Jymmm> Just smash your foot, then the finger won't hurt anymore ;)
[22:11:17] <Frank___> which is the best drill material for steel? hss'
[22:11:20] <Frank___> haha
[22:11:41] <Tom_itx> i've often needed a long reach press. a tabletop is too short but a floor model is too tall
[22:11:59] <Jymmm> Tom_itx: 8" ?
[22:12:03] <Tom_itx> would be nice to find something inbetween
[22:12:08] <_methods> radial drill press lol
[22:12:14] <os1r1s> bensbenz You still around?
[22:12:36] <Jymmm> Tom_itx: CNC Router with drill chuck =)
[22:13:04] <Frank___> im getting sad over here nobody ansers my little question : (
[22:13:15] <Tom_itx> not good for drilling 1.5" holes
[22:13:28] <Frank___> just 3/8''
[22:13:39] <Tom_itx> some coated drill
[22:13:54] <Frank___> sweet, tahnks
[22:14:20] <Tom_itx> any drill will do if you use cutting fluid
[22:14:30] <Tom_itx> well any drill you could call a drill
[22:15:04] <Jymmm> Frank___: not drilling SS r hardened stuff are you?
[22:15:07] <Jymmm> or*
[22:15:11] <Frank___> yeah, but i have to do like 3 foot of drilling
[22:15:20] <Frank___> no, just plain normal steel
[22:15:21] <_methods> the hougen has a coolant ring built into the spindle too
[22:15:21] <Tom_itx> at least spot the holes first or that big a drill could wander since they're probably not true centercutting
[22:15:22] <Frank___> a 36?
[22:15:26] <_methods> which is a nice addition
[22:15:35] <CaptHindsight> Tom_itx: not that you build one but I found a floor model cut down to benchtop
[22:15:37] <Frank___> yes a nice centerpunching
[22:16:02] <CaptHindsight> Tom_itx: not that you could not build one
[22:16:08] <Tom_itx> CaptHindsight, last time i needed it, i turned the table model sideways over the table :D
[22:16:56] <Tom_itx> clamped it in place
[22:17:47] <CaptHindsight> heh, seems I always end up needing to drill a 1/4" dia hold 3/8" deep into something 8 ft long
[22:17:56] <CaptHindsight> hold/hole
[22:18:01] <Frank___> yes, actually i have a bench drill, i could adjust the base to make it fit underneath the 4'' tube steel

[22:18:43] <Tom_itx> plated soft iron

[22:19:35] * Jymmm smacks Tom_itx with a clue-by-four 2015-12-29.14:15:11 Frank___: yeah, but i have to do like 3 foot of drilling
[22:19:51] <Tom_itx> not just one hole
[22:19:57] <Frank___> linear
[22:20:09] <Frank___> 3 foot cuz 55holes x 3/8'' aprox
[22:20:12] <Frank___> actually its 5mm
[22:20:14] <Frank___> holes
[22:20:39] <Jymmm> Frank___: they have pre perfed plate =)
[22:21:08] <Frank___> its tube already welded to a frame
[22:21:17] <Frank___> or made into a frame,
[22:21:20] <Jymmm> ah
[22:22:08] <Frank___> my options guessing are, mag drill (rent) or the bench drill on a special base to fit underneath the tube
[22:27:44] <CaptHindsight> Jymmm: sounds like zinc plated soft iron
[22:28:54] <CaptHindsight> soft/white iron

[23:37:25] <CaptHindsight> whats the energy efficiency work out between 2-cycle engine + fuel and generator vs densest lithium batteries?
[23:37:51] <toastyde1th> 2-cycle is way, way less efficient bure more power dense
[23:38:10] <toastyde1th> but that depends on what generator you use
[23:38:14] <toastyde1th> *but
[23:38:25] <CaptHindsight> Gasoline has an energy density of about 45 megajoules per kilogram (MJ/kg)
[23:38:51] <toastyde1th> if you're getting your power off a good thermodynamic cycle, like a real powerplant, the batteries win by a pretty good margin. tesla has some good numbers on this but i am having trouble finding them
[23:39:21] <toastyde1th> but internal combustion engines, even ideally, are not very good thermodynamic cycles
[23:39:36] <toastyde1th> and their peak efficiency happens in the hardest place to engineer, right at the top of the stroke
[23:39:55] <CaptHindsight> yeah there are several studies
[23:40:21] <toastyde1th> so if you were to burn that gas and feed a dual-cycle gas turbine, that would be much more efficient
[23:40:26] <toastyde1th> even with generation losses
[23:40:57] <CaptHindsight> I'm surprised that they went 2-cycle except for if they somehow treat gasoline like it's easy to get in the filed vs some battery charger
[23:41:10] <CaptHindsight> easy/easier
[23:41:26] <toastyde1th> it's probably power density + availability of fuel
[23:41:37] <toastyde1th> it's hard to beat two strokes on power density
[23:41:57] <CaptHindsight> I guess we need some kind of fat powered battery :)

[23:44:34] <enleth> as is booze
[23:44:42] <enleth> both would do in a pinch
[23:45:27] <toastyde1th> i would not use booze but the availability of other fuel sources is large
[23:45:39] <enleth> performace will drop with makeshift fuels but a good purpose built ECU could compensate
