01:02 AM IchGucksLive: hi
01:07 AM jesseg: howdy IchGucksLive !
01:08 AM IchGucksLive: ;-)
01:15 AM IchGucksLive: later
01:41 AM archivist: gloops, I think that seller is a bit pricey
01:42 AM gloops: not really giving it away
01:45 AM archivist: watchmakers lathes pass between those in the trade with collets 150-300 ish
01:46 AM archivist: the silly selling of glass fitting tool with its dies in a separate auction
01:49 AM gloops: it is pricey after another look
01:50 AM archivist: I have had the odd lathe in my watch list a while, seeing how long before he drops his price
01:58 AM gloops: he'll be lucky to get that for it
02:00 AM archivist: I have watched items for a year or more for a giggle
02:00 AM archivist: silly sellers
02:02 AM gloops: well if you dont need the money or space, its probably the best way to sell, start high and come down
02:02 AM gloops: that lot would go for nothing at an estate sale
02:04 AM archivist: I dunno, I bet many just dismiss those items and carry on looking at others, the 99p start guys have a better feedback
02:05 AM gloops: 4 V blocks for £20 - someone needing v blocks would be tempted, although yeah a 99p start i could see them fetching more than that
02:05 AM gloops: or not
02:06 AM archivist: 4 mixed or a proper matched set
02:06 AM gloops: looks like a set
02:11 AM archivist: rofl http://www.oldtools.co.uk/clamps-vices/3991-moore-and-wright-vee-blocks-and-clamp-no502.html
02:12 AM archivist: https://www.ebay.com/itm/Moore-Wright-engineers-precision-vee-blocks-1-1-2-2-pair-502-vintage-/173030976282
02:13 AM archivist: even more rofl https://www.ebay.co.uk/itm/Clamp-to-suit-Moore-Wright-502-/171658821227
02:13 AM archivist: bent and buggered
02:14 AM gloops: i got an odd one off the car boot for £2 heh
02:14 AM Deejay: moin
02:15 AM archivist: I have a pair I got new best part of 40 years ago, draper still in the box
02:16 AM gloops: still garages and sheds full of stuff in sheffield, occasionally a rat with a van gets to clear one out and it ends up at the car boot - the good stuff usually gone as daylight breaks
02:16 AM archivist: I dont rate moore and wright that highly either
02:17 AM archivist: I stopped chasing car boots some time ago
02:17 AM archivist: I sometimes drop into the local antique shop to check for tools
02:18 AM gloops: made one mistake last year, bloke with a few boxes of taps dies and miscellaneous, must have been hundreds of taps etc, a lot in old small tobacco tins and biscuit tins, wanted 40 quid, offered 30 and he said no so i walked off, meaning to go back round, forgot all about it till i was driving home
02:20 AM archivist: pounce when there!
02:21 AM gloops: i should have heh, i was trying to reckon the value up, few hundred quid plus easily, the tins might have been worth more than the tools
02:26 AM archivist: when I had a proper job I used to go to a lot of fairs looking for tools, technical books etc
02:28 AM gloops: there is a plant and machinery auction at doncaster, never been, not sure what stuff goes for
02:29 AM gloops: if it is still going - probably online anyway now so will have been discovered
04:02 AM dan3wik is now known as dan2wik
04:12 AM gloops: right, first chance ive had to yank a plate around thats fitted to the gantry, i have established so far :-
04:13 AM gloops: 60x40 4mm box section IS strong enough over 1150mm
04:13 AM gloops: sbr bearings are strong enough
04:13 AM gloops: 12.7mm all plate IS NOT strong enough
04:15 AM archivist: my mill column is ally, needed a lot extra to make it rigid
04:15 AM gloops: its the only weak point in this, nothing else is moving - enough that matters or can be seen anyway
04:16 AM archivist: dont worry, whatever is still wrong will bite later :)
04:16 AM archivist: best way to learn
04:17 AM gloops: its not shocking, much better than the old one, but its there
04:18 AM gloops: so the rails added might make it good enough
04:21 AM gloops: the curvature of the plates is enough to bind the bearings as well, that needs sorting
04:21 AM archivist: off for drivin miss daisy
04:21 AM gloops: have a nice day
04:22 AM archivist: just an hour then back
04:23 AM archivist: they would pick a reasonable window fitting day
04:35 AM jthornton: morning
05:49 AM Tom_L: morning
05:49 AM Tom_L: 47°F
05:51 AM jthornton: same and wet
05:51 AM Tom_L: yeah it was misty yesterday too
05:52 AM Tom_L: cloud cover probably kept the temp up
05:52 AM * jthornton tries to figure out what the heck MIMEText is
05:54 AM XXCoder: light rain
05:55 AM XXCoder: just enough to make basement leak water a little bit, not as bad now as we now have tubes leading roof water well away from fountain
05:55 AM XXCoder: whatever concerete part of house is called :P
05:59 AM jthornton: foundation
06:01 AM XXCoder: thanks
06:17 AM jym: JT-Shop: what about MIME/TEXT ?
06:17 AM jym: err jthornton ^^^
06:18 AM jthornton: just fingering out how to add to the message so my chickens can email me
06:20 AM jym: JT-Shop: MIMETYPE/CHICKENSCRATCH
06:20 AM archivist: to cluck@chicken.coop.net subject are you on the menu?
06:23 AM jym: jthornton: mailto://farmer-john@?subject=henhouse?&body=Advice_from_chickens..._Feed_the_chickens!
06:25 AM jym: mailto://farmer-john@?subject=henhouse?&body=Advice_from_chickens...%0D%0AFeed_the_chickens!
06:28 AM jym: mailto://farmer-john@?subject=henhouse?&body=Advice+from+chickens...%0D%0AFeed+the+chickens!
06:28 AM jym: DOH
06:29 AM jthornton: I also want to set up two loop detectors on the driveway to email me when someone enters or leaves the property
06:29 AM jym: mailto://farmer-john@?subject=henhouse?&body=Advice%20from%20chickens...%0D%0AFeed%20the%20chickens!
06:29 AM jthornton: now you just flooding the channel
06:29 AM jym: Ok, th elast one worked )the previous one should have too, but eh)
06:30 AM jym: jthornton: I was giving the syntax to included spaces if you cared to use that format
06:30 AM jthornton: I'm using python
06:31 AM jym: Doesn't matter, URL syntax is an RFC thing, not a language thing.
06:32 AM jthornton: that's not how you do it in python
06:32 AM jym: as is MIME encoding
06:34 AM jthornton: https://paste.ubuntu.com/26220941/
06:35 AM jym: ALL languages need to adhere to the RFC's... https://tools.ietf.org/html/rfc1341
06:35 AM jym: You are using a lib, is why it looks "different" to you.
06:37 AM jthornton: and that's why your examples mean nothing to me
06:40 AM jym: jthornton: Had no clue what you were doing, just heard "Mimetext" is all =)
06:42 AM jym: jthornton: You should get/use twitter and give the chickens their own twitter feed =)
06:44 AM jym: jthornton: Bummer, already taken... https://twitter.com/chickenscratch
06:45 AM SpeedEvil: http://forum.nasaspaceflight.com/index.php?action=dlattach;topic=41015.0;attach=1465996;image When your shop is just big enough.
06:45 AM * jthornton doesn't do twitter
06:46 AM jym: SpeedEvil: But, did they build to accomidate the building, or the building to accomidate the rocket?
06:46 AM SpeedEvil: The building is older IIRC.
06:47 AM jym: ah
06:49 AM gloops: not seen miss0r lately
06:52 AM archivist: he is never regular
07:00 AM XXCoder: last saw was few days ago
07:04 AM gloops: that little john is getting some bids https://www.ebay.co.uk/itm/Raglan-Little-John-Lathe/263387374119?
07:21 AM archivist: what a surprise... a week later same day and the connection fault seems fixed with me doing nothing
07:24 AM XXCoder: VOODOO! High tech voodoo!
07:30 AM archivist: high tech stupidity somewhere in the internet
08:01 AM mikosae: Hi everybody I'm currently searching for parts to put together a new desktop PC for my mill
08:04 AM mikosae: I have a 4axis machine which has an BOB from Benezan. In for being more flexible for further machinedevelopments in the next years I would be willing to invest in a Mesa-card but have no clue wich one to decide for.
08:07 AM IchGucksLive: hi from rainy germany
08:07 AM mikosae: In general when I look for example here http://www.shop.cncmonster.de/LinuxCNC:::84.html what are all these cards for ??
08:07 AM IchGucksLive: hi
08:07 AM IchGucksLive: mikosae: Ethernet or parport
08:08 AM IchGucksLive: or fpga general
08:08 AM IchGucksLive: the benezan can be replaced by a real cheep ultra 12/4
08:08 AM IchGucksLive: this has VFD capability
08:09 AM IchGucksLive: then you can decide on going ethernet by 7i92m
08:09 AM mikosae: Since I would buy a new computer anyway I would guess I could redecide if ethernet or parport
08:09 AM mikosae: ?
08:09 AM IchGucksLive: or if you start comledly over go cheep with the 12/5
08:10 AM IchGucksLive: mikosae: where in the world are you
08:10 AM mikosae: Wien :)
08:10 AM IchGucksLive: dann sollte es auch in deutsch gehen
08:10 AM mikosae: jup
08:10 AM mikosae: geren
08:11 AM IchGucksLive: drück mal doppelt auf menein nick oder ist schon ein fesnster augegangen
08:11 AM IchGucksLive: ah ok
08:36 AM FinboySlick: If you can get over the japanese dramatics, anyone able to tell me what lathe Masaharu Saito is using in this challenge? https://www.youtube.com/watch?v=pCtWPbTDbuY
08:40 AM MarcelineVQ: timestamp?
08:43 AM FinboySlick: https://youtu.be/pCtWPbTDbuY?t=1086 is probably as good a shot as there is.
08:44 AM FinboySlick: It's one heck of a challenge, btw.
08:44 AM FinboySlick: (dramatics aside)
08:44 AM MarcelineVQ: it's fine with with mute on hoho
08:44 AM IchGucksLive: FinboySlick: the drill clamp is the best
08:45 AM MarcelineVQ: yeah the dramatics are one of those cultural quirks that I never quite understood, but I'm sure there's just as many here they're just not obvious because I'm used to them
08:45 AM FinboySlick: IchGucksLive: You mean the tailstock chuck?
08:46 AM IchGucksLive: yes
08:46 AM IchGucksLive: 0,05 is hard to clamp
08:47 AM IchGucksLive: but as pencil has 1,2mm
08:47 AM IchGucksLive: i guess he used 0,5
08:47 AM FinboySlick: The pencil lead is 0.5mm
08:47 AM gloops: expensive chuck
08:47 AM FinboySlick: He used 0.3 drill.
08:48 AM gloops: there was a story in a place i worked as a kid, the japanese sent what they claimed was the worlds thinnest drill bit to this sheffield firm - who sent it back with a hole down the centre haha
08:48 AM Rab: Surprised he's trying to chuck it instead of using/making a collet.
08:48 AM Rab: But maybe that's part of the challenge.
08:49 AM FinboySlick: No, the challenge is just to drill the 60mm lead through length-wise. Whoever drills the deepest without breaking it wins.
08:50 AM FinboySlick: I won't spoil it if you guys want to watch it, but part 2 is hard to find.
08:51 AM MarcelineVQ: gloops: I like that
08:52 AM gloops: Marcel i never actually saw any of this but a lot of guys swore it was right
08:52 AM MarcelineVQ: every area has it's little legends, they're as useful to people true or false
08:53 AM archivist: that story is old here it is claimed to be RR that did the hole down the middle
08:55 AM FinboySlick: His first try, he was holding the lead in a chuck too.
08:56 AM MarcelineVQ: hey neat find http://uhv.cheme.cmu.edu/procedures/machining/ch7.pdf starts at http://uhv.cheme.cmu.edu/procedures/machining/ch1.pdf
08:56 AM FinboySlick: Almost made it through but the 0.01mm wall collapsed under claming pressure.
08:56 AM gregcnc: I would guess an old okuma or mori seiki they don't show an overall
08:56 AM MarcelineVQ: ah it's from http://uhv.cheme.cmu.edu/procedures/machine.html which is from http://uhv.cheme.cmu.edu/guides.html
08:58 AM MarcelineVQ: Just tried that shrink-wrap window treatment last evening, went quite well and looks nice with a little thought put into how the edges should turn out. I reccomend it if your windows are un-intentionally drafty
08:59 AM SpeedEvil: :)
08:59 AM FinboySlick: MarcelineVQ: Last I had my house checked, it had 11.2 complete air changes per hour.
09:00 AM FinboySlick: So I'm trying to build a new one now.
09:02 AM gregcnc: that must be an awfully nice tailstock to feel resistance wile drilling Ø0.3
09:03 AM gregcnc: in a pencil lead
09:10 AM MarcelineVQ: shoulda used a drill with ports to blow out the dust, one shot drilling, make the edm guy look like a chump. now, to find a 0.3mm drill with ports, can't be that hard :>
09:13 AM gregcnc: you probably won't find one with 60+mm of flute
09:18 AM SpeedEvil: Take 5mm moderate carbon bar, drill 3mm hole, anneal, draw, repeat, draw square, twist, sharpen.
09:19 AM SpeedEvil: May need to fill the hole with something meltable out.
09:19 AM FinboySlick: SpeedEvil: He just drilled it.
09:20 AM SpeedEvil: I mean to make a hollow drill
09:20 AM FinboySlick: Oh.
09:21 AM SpeedEvil: Actually, at that diameter, mild steel would be very easy to carburise
09:22 AM SpeedEvil: But that may distort it I suppose
09:22 AM MarcelineVQ: use edm to make the ported drill bit
09:22 AM MarcelineVQ: now who's winning
09:23 AM SpeedEvil: In principle, sure. But a 0.05mm hole in a 0.1mm or so clear space between flutes 60mm deep - you first.
09:26 AM MarcelineVQ: :>
09:28 AM SpeedEvil: I have idly wondered about using magnets for this when drilling aluminium.
09:28 AM SpeedEvil: Sense magnetically
09:29 AM gloops: Britain ranked 1st for 1st time in Forbes list of best country to do business. Forbes says of Brexit: 'economy has held up relatively well. Britain’s business climate remains attractive. UK ranks first in Forbes’
09:29 AM gloops: onwards and upwards!
09:29 AM SpeedEvil: https://hackaday.com/2010/02/26/drilling-perfectly-centered-holes/ however
09:30 AM SpeedEvil: self centering drillbits are a thing
09:30 AM SpeedEvil: gloops: Seems like the cocaine market is holding up well.
09:32 AM gloops: this is only the beginning SpeedEvil
09:32 AM MarcelineVQ: gloops: a few more articles like that and your elected representatives might actually do the job they were voted in to do instead of actively supressing the will of the people they represent. or something like that
09:33 AM MarcelineVQ: er to be less general I'm specifically referring to the pushback against actually working towards brexit there is in the estblishment
09:33 AM gloops: yes a lot of half hearted paying lip service and so on atm Marcel, instead of getting on with it
09:34 AM MarcelineVQ: SpeedEvil: hoho, they're using a press like a lathe? wonderful
09:35 AM SpeedEvil: MarcelineVQ: I was more referring to teh general concept of self centreing drillbits - it's in the design of the bit, not what you use
09:40 AM gregcnc: well gundrills
09:41 AM MarcelineVQ: this reminds me actually I​ need to cobble together a bit sharpening + wood lathe tool sharpening jig
09:43 AM mikosae: Does anyone know a list like this http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Latency-Test for modern hardware?
09:43 AM cradek: I don't think there is one
09:44 AM mikosae: :( any personal recommendations?
09:44 AM cradek: it's fundamentally hard to have the list you want, because you can order the same thing on two adjacent days and get different hardware
09:45 AM mikosae: mhm i see
09:45 AM cradek: most desktop boards work fine, just test one that you have nearby
09:45 AM mikosae: the fact is I need a new pc for my mill and want to buy a new one
09:46 AM FinboySlick: mikosae: Otherwise, buy a few cheap motherboards and see which one works best.
09:46 AM mikosae: is there anything like "onboard graphics" or other stuff that I should avoid?
09:47 AM FinboySlick: I guess that now that the ME can be hacked, there may be a lot of extra potential tweaking done to improve latency on otherwise poor performing boards.
09:47 AM cradek: avoid low power, laptop-like boards
09:47 AM cradek: get slots so if you have a problem with graphics you can just plug in a card
09:47 AM mikosae: mh I would rather spend some euros more that tweaking some days to get it working
09:47 AM gregcnc: finboyslick what does that mean?
09:48 AM gregcnc: that's the thing, more cost doesn't necessairly mean better
09:48 AM Rab: Probably want to avoid anything with advanced power saving features, and/or turn them off; that's why laptops perform poorly.
09:49 AM mikosae: mhm ok
09:49 AM gregcnc: seems like newer stuff with thermal management is tricky sometimes
09:50 AM FinboySlick: gregcnc: the Intel ME may be quite a source of latency spikes and now there are ways to disable a large part of it.
09:51 AM Rab: The corollary of that is, if you get a new PC and it appears to perform poorly, dig into the BIOS settings and try experimenting with various combinations of settings.
09:52 AM mikosae: are there arguments against µATX boards?
09:52 AM FinboySlick: mikosae: I use one and it's pretty nice.
09:52 AM mikosae: ok is it still available?
09:53 AM FinboySlick: mikosae: No. Actually, it wasn't available when I bought it but I found old stock... That was a few years ago though.
09:54 AM mikosae: mh :/
09:55 AM mikosae: Somehow it seems like an uncommon idea
09:55 AM Rab: I bought one of these a couple of years ago, this particular model had a good rep for latency and performance w/linuxcnc: https://www.ebay.com/itm/HP-dc7800-SFF-Intel-Core-2-Duo-E6550-2-33-GHz-RAM-2GB-80GB-Hard-Drive-/272855918563
09:55 AM Rab: Core2Duo is getting rather long in the tooth though. I know you are looking for a new build.
09:57 AM Rab: But personally, I would look for an off-lease turnkey business PC (IBM, Lenovo, HP). If it performs well, you have a standardized thing to use in the future. Easy to find more for redundancy, shop expansion, etc.
09:58 AM mikosae: I just had my "only 7 years old" quadcore board dying and I don't want to run ito that with my millpc too
09:58 AM Rab: Fair enough.
10:05 AM mikosae: FinboySlick: Is yours with an onboard parport or have you found a parportcard which is slim enough?
10:09 AM Rab: mikosae, maybe this is obvious, but if you get a Mesa FPGA card then host PC performance is less of an issue. Mesa card + cheap PC + not having to mess with evaluating a bunch of hardware might put you out ahead.
10:11 AM mikosae: mh yeah I just had a longer discussion about fpga or not with IchGucksLive
10:11 AM mikosae: and following to his oppinion I don't need a mesacard because I run steppers only and work on wook anyway
10:13 AM mikosae: but yes I'm still thinking of allthough too
10:14 AM mikosae: I wouldn't mind some euros extra for milling peacefully the next years
10:23 AM FinboySlick: mikosae: It has an on-board parport and is what I'm using now. I have a MESA card too that I haven't even unpacked yet :P
10:30 AM mikosae: I don't know if I really want to spend another day on researching and trying hardware that might give me good latency results
10:36 AM roycroft: i'm not sure i understand how using stepper motors makes latency irrelevant
10:37 AM mikosae: Did I understand right something like this http://www.shop.cncmonster.de/LinuxCNC/PlugnGo-Kits:::84_124.html and any random pc wher the card fits in would make it ?
10:38 AM stelios: hello anyone here that can help me with some feed n speed suggestions?
10:38 AM mikosae: roycroft: his argument was that for my machine the computer doensn't need to be soo fast (like it would need to be for seros)
10:38 AM gregcnc: roycroft if step frequency is within hardware capability ie low resolution for wood router
10:39 AM roycroft: sure
10:39 AM roycroft: i get that steppers are less sensitive to latency than servos, generally
10:39 AM roycroft: but it can still be an issue
10:40 AM mikosae: yeah of course
10:41 AM roycroft: perhaps i am overly concerned about it, but i bought a system board with very low latency (based on a recommendation on this channel), and still get a mesa 5i25, and will be using stepper motors in my initial setup
10:41 AM mikosae: and if plug-n-go mesa kits would solve my hardware decision what should i look to choose "the right" one?
10:42 AM roycroft: it just seemed an inexpensive and prudent thing to do
10:42 AM mikosae: oh ok
10:42 AM mikosae: so I do have to care about the mainboard latency that I'm running the mesacard with?
10:43 AM roycroft: mikosae: this is a good place to ask about them - pcw_mesa is with mesa, and jt-shop is a mesa reseller
10:43 AM roycroft: both are quite active on this channel
10:44 AM roycroft: i'm not an expert in the matter, but i'd say that system board latency is much less a factor if you use a mesa fpga board
10:44 AM mikosae: mh ok
10:45 AM roycroft: if it's extremely high it may still be of concern, but i'll defer to the experts to discuss it better
10:46 AM mikosae: roycroft: can't find jt-shop
10:46 AM roycroft: just mention "mesa" once in a while
10:46 AM gloops: stelios what are you cutting?
10:47 AM roycroft: and pcw* or jt* will eventually wake up and respond :)
10:47 AM roycroft: they're both on channel right now, but idle
10:47 AM stelios: i am cutting aluminum following these types for feeds www.cncroutershop.com/us_en/calculate-feeds
10:48 AM gloops: are those ratios not working for you?
10:48 AM stelios: but they work nice if lets say i cut 0.2mm DOC and i dont know how to calculate the right feed if i need to cut 0.5mm for ex DOC
10:49 AM mikosae: roycroft: I see you are talking about other users ;)
10:50 AM stelios: with the 3mm carbide bit 1F . it say that the chip load is 0.1. So at 18.000 RPM i need a feed of 1.800mm/m
10:50 AM mikosae: roycroft: are they resellers of mesacards in europe?
10:50 AM gloops: hmm, someone can probably help - im not an aluminium cutter..yet
10:50 AM stelios: it cuts nice with this speed if i cut 0.1-0.2 mm DOC
10:51 AM SpeedEvil: stelios: what does it do when it stops 'cutting nice'
10:51 AM roycroft: no, i don't think there are any .eu resellers
10:51 AM roycroft: the mesa cards are not widely used in .eu because of that
10:52 AM SpeedEvil: Cutting force is proportional to depth of cut (sort-of) if cutting forces rise, machine rigidity gets more important, and load on the spindle of course goes up
10:52 AM stelios: lot of noise SpeedEvil.
10:52 AM roycroft: and because the germans are cheapskates :P
10:52 AM roycroft: at least ours are :)
10:52 AM mikosae: there are resellers " Dealers in Europe: http://shop.cncmonster.de or http://www.retrofit-plus.at or http://www.duzi.cz/shop_cnc/index.php?main_page=index&language=cz Dealers in Europe: http://shop.cncmonster.de or http://www.retrofit-plus.at or http://www.duzi.cz/shop_cnc/index.php?main_page=index&language=cz Dealers in Europe: http://shop.cncmonster.de or http://www.retrofit-plus.at or http://www.duzi.cz/shop_cnc/index.php?main_page=index&language=cz
10:52 AM SpeedEvil: stelios: vibration of course rises too, and may excite oscillations.
10:53 AM SpeedEvil: stelios: try covering your machine in a thick coat of salami to reduce vibration.
10:53 AM mikosae: roycroft mentioned on the mesa wiki site
10:53 AM roycroft: oh cool
10:53 AM roycroft: i sit corrected
10:54 AM roycroft: it's been mentioned here that they're not used much in .eu because they're hard to get there
10:54 AM roycroft: i was basing my statements on that
10:54 AM stelios: "salami"?
10:54 AM roycroft: but i've not gone to europe and tried to buy one
10:54 AM SpeedEvil: stelios: Not quite serious - but anything to absorb vibration.
10:54 AM DaViruz: it's not hard at all, just order one from mesa
10:54 AM mikosae: roycroft: I'm not taking it personally :)
10:55 AM roycroft: daviruz: i suspect, then, that the real reason that those her who do not like them is false frugality, not availability
10:56 AM stelios: Ok. But the think i need to understand is if i cut at 0.1mm DOC with 1800mm/m when i need to go to 0.5 DOC how much i should reduce the speed so i reduse the cutting forces?
10:56 AM gloops: what spindle?
10:57 AM stelios: 24000 rpm 1.5kw china spindle
10:57 AM mikosae: I'm in europe and the more I think about the more likely it is that I'll just get one and don't care about testing mainboards anymore
10:57 AM phipli: evening
10:58 AM gloops: well a lot cut with those spindles stelios, was just thinking you might have some runout
10:59 AM gloops: end of the the day, testing is probably best, do some test cuts different feeds
10:59 AM gregcnc: the problem is reducing speed doesn't reduce forces, only depth of cut will reduce forces and thus vibration
10:59 AM gregcnc: if the cuttign frequency is exciting(resonance) the machine frame that si different
11:00 AM gloops: yes what machine is this stelios?
11:01 AM stelios: Yes but with the same speed and more DOC the radial force makes the bit curve. so it brakes
11:01 AM stelios: 3040 ballscrew chinese one.
11:01 AM gregcnc: so you're stuck with low depth of cut I've been there
11:02 AM SpeedEvil: stelios: If you're breaking cutters due to having too much cutter engaged with the work, you can only go slower if you want the same depth of cut. Or increase RPM
11:02 AM gloops: could i ask stelios, if you press hard on the bottom of your z - does it move at all?
11:02 AM gloops: i mean, at all
11:02 AM SpeedEvil: Unless the machine is vibrating and breaking the bit due to irregular chip loads
11:03 AM archivist: lack of lube and metal sticking in the flutes
11:03 AM stelios: yes it moves. This is what i am asking with the radial forse it causes the z to move VERY little and then it brakes
11:04 AM gloops: so deflection in the machine
11:05 AM roycroft: i got a 5i25 + 7i76 and a 7i73 for pendant control for the cnc conversion i'm doing, which will use stepper motors
11:06 AM roycroft: i should finish that project some day :)
11:06 AM roycroft: it got pushed on the back burner twice
11:06 AM stelios: so is there a way to calculate the speed to a slower one to reduse the deflection of my z axis and cut better in more DOC but not very slow to increase temps?
11:07 AM gregcnc: 0.1mm pet tooth is quite a bit for a 3mm cutter
11:07 AM roycroft: i have all the hardware except the ball screws
11:08 AM gloops: The First 4 criteria.
11:08 AM gloops: A) Rigidity.
11:08 AM gloops: B) Rigidity
11:08 AM gloops: C) Rigidity
11:08 AM gloops: D) Rigidity
11:08 AM gregcnc: in reality it will take some testing, start at something low like 10-20% but make sure you can get the chips out and use some coolant to avoid melting the stock
11:08 AM roycroft: those are rather inflexible criteria, gloops
11:08 AM stelios: now i run the machine in .3mm DOC at 18.000 rpm at 800mm/m with the 3mm 1F bit
11:09 AM SpeedEvil: Two flute may help
11:09 AM gloops: roycroft this is from a sherline user
11:09 AM SpeedEvil: stelios: what'er you cutting
11:09 AM stelios: aluminum
11:10 AM SpeedEvil: cutting fluid may help a little
11:10 AM gregcnc: 0.04mm per tooth is not unreasonable
11:10 AM gloops: clamping the work as well
11:13 AM gregcnc: Depending on how sharp the cutter is you could go as low a 0.015mm/tooth
11:13 AM stelios: yes but i dont understant this: with .1mm DOC 1800mm/m the chip load is 0.1 and it cuts nice. with 0.3 DOC and 800mm/m the chip load is 0.04 and it cuts nice
11:13 AM stelios: so what is the "correct" chip load i need to culculate to find the best feed?
11:13 AM gregcnc: whatever actually works
11:14 AM gregcnc: it's a combination of cutter, machine, runout, material, coolant,........
11:14 AM archivist: find one that works and use it
11:14 AM gregcnc: high volume shops go to great lengths with testing to find thsoe data points
11:15 AM gloops: yes, if i put my belly on the bottom of the z and push with some weight i can still it moving
11:15 AM * gloops is pretty obsessed with rigidty atm
11:18 AM SpeedEvil: gloops: It gets quite simple if your machine is absolutely rigid and your material does not deflect
11:19 AM SpeedEvil: gloops: otherwise it's almost essentially impossible to calculate simply and you need to do detailed simulation
11:19 AM SpeedEvil: Or just try stuff
11:19 AM Deejay: re
11:19 AM gloops: yes i would agree SpeedEvil, i am pretty close to what i wanted anyway now
11:27 AM gregcnc: fun read ~900 pages http://bit.ly/2oY9i5j
11:29 AM gloops: maybe some useful info re speeds n feeds here http://madmodder.net/index.php?topic=4678.0 in simple terms
11:36 AM stelios: tnx for this gloops i will check it
11:52 AM anonnumberanon: my horizontal bandsaw at Harbor Freight no longer has a rebate it's too expensive now :(
11:52 AM anonnumberanon: the red one
11:55 AM roycroft: it will be on sale again soon
11:55 AM roycroft: it always is
11:56 AM roycroft: there will probably be only one more 25% off coupon this year
11:56 AM roycroft: but there will always be 20% off coupons
11:59 AM roycroft: and it's done - my taxes just went up, and health care just became even more unaffordable
12:00 PM roycroft: i hope the filthy rich don't get too stressed out over all that extra money that they're taking from me
12:00 PM roycroft: it's going to take them a lot of time to count their windfall
12:02 PM gloops: stelios one way you can reduce the deflection is to raise the height of the bed - i dont know say you have 120mm drop on the z, the alu youre cutting is 20mm thick, youre cutting at the worst point on the z where leverage is greatest
12:03 PM gloops: get a slab of something, granite or even a strong wooden block or frame and lift the workpiece up to the cutter
12:03 PM gloops: i wont bend closer to the gantry - no leverage in play
12:03 PM gloops: it
12:05 PM gloops: anonn - january sales soon
12:05 PM roycroft: everything that goes on sale at hf goes on sale at least 6xyear
12:06 PM roycroft: 6x/year
12:06 PM IchGucksLive: hi
12:06 PM roycroft: and you can find a valid 20% off coupon about 360 days/year
12:07 PM gloops: i dont think we have HF here, not under that name anyway
12:07 PM roycroft: the ohmygoditsalmostchristmasyouhadbetterbuythisnow sales are almost over
12:07 PM roycroft: but the christmasisoverandwehavealotofleftoverstuff sales will begin on tuesday next
12:09 PM gloops: how do our cheap tool outlet prices compare? https://www.machinemart.co.uk/p/cbs45md-41-2in-x-6in-metal-cutting-ban/
12:10 PM roycroft: that's pretty expensive, gloops
12:10 PM roycroft: that saw is US$259 here
12:10 PM gloops: £322 i guess thats about 380$
12:10 PM roycroft: and it's £269 + vat there
12:11 PM gloops: yes we are doomed
12:11 PM roycroft: i like the baby blue color though
12:11 PM gloops: to use angle grinders
12:11 PM roycroft: much more pleasing to the eye than the green or red that ours are painted
12:11 PM roycroft: it's amost a muted turquoise
12:12 PM roycroft: but not worth £100 for the nice paintjob
12:15 PM gloops: i dont rate their tools anyway
12:27 PM stelios: Hello IchGucksLive
12:27 PM IchGucksLive: :-
12:36 PM IchGucksLive: does someone know git
12:36 PM jym: IchGucksLive: Linus does.
12:37 PM IchGucksLive: im shure
12:37 PM jym: IchGucksLive: If you have a specific question, that might be beter
12:38 PM IchGucksLive: i did some changes and commit
12:38 PM IchGucksLive: now it asks at git checkout master to git pull against
12:39 PM IchGucksLive: and opens a Merge terminal to get a name in but how do i close this to get on
01:13 PM IchGucksLive: Gn8
01:56 PM * JT-Shop was at the industrial park working
01:58 PM gloops: shapeoko flex https://www.youtube.com/watch?v=TtQzqbLscHE
01:59 PM gloops: suppose its only $1100 for the kit
02:13 PM gloops: CNC Mogul https://www.youtube.com/watch?v=e4qe-vDT_l4
02:15 PM gloops: $1300
03:16 PM FinboySlick: gloops: Carve it from a single block of granite.
03:17 PM FinboySlick: Chisel and patience...
03:17 PM gloops: thought about it Finboy, my wrist is a bit dodgy though, dont want to risk it
03:19 PM gloops: something has come to mind though, my z axis is now so heavy it would chop my fingers clean off if it dropped on them
03:33 PM XXCoder: gloops: nice deflection!
03:34 PM XXCoder: seriouisly nice. 2 mm or what? lol
03:38 PM gloops: lol, a lot more with some proper push
03:38 PM JT-Shop: I wonder if you need special wire for a vehicle loop detector?
03:38 PM gloops: 5-8mm
03:38 PM jym: JT-Shop: Just 12ga
03:39 PM jym: JT-Shop: Goof old househould electrical wire is fine
03:39 PM jym: good*
03:39 PM jym: err stranded
03:40 PM JT-Shop: stranded it better than solid?
03:40 PM jym: JT-Shop: Easier to shove in the slot in the asphalt/concrete
03:41 PM JT-Shop: jym: what asphalt/concrete?
03:42 PM jym: JT-Shop: Well, that's what most street lights have. If you have dirt, then I'd think about making it a bundle and burrying it
03:42 PM jym: like a giant degauisung coil
03:42 PM jym: (sp)
03:42 PM JT-Shop: nope most streets here are chat
03:42 PM JT-Shop: I know what you mean
03:43 PM XXCoder: chatty roads
03:43 PM jym: JT-Shop: The more turns you hae, the more sensative it can be, which you can adjust down on the controller
03:43 PM JT-Shop: I have a bunch of THHN wire that I can use, just do a donut with the tractor with the single point down lol
03:44 PM jym: lol
03:45 PM JT-Shop: https://www.aliexpress.com/item/Vehicle-Detector-Loop-Detector-To-Sense-Vehicle-Inspection-Device-Traffic-Inductive-Signal-Control-PD132/32801002880.html
03:46 PM XXCoder: one thing I hate about aliexpress is that they use basically use all words
03:46 PM XXCoder: for cnc: cnc router mill lathe 3d printing
03:46 PM XXCoder: and its a stepper
03:47 PM jym: JT-Shop: Nice find, if you get 12V you can make it solar down the road.
03:47 PM JT-Shop: when I'm not here I want my rpi to email me when someone enters or leaves the driveway
03:47 PM XXCoder: solar down the road?
03:48 PM JT-Shop: yea they are 12v
03:49 PM jym: JT-Shop: if you get/use TWO sensors, then you can tell which way they are traveling
03:49 PM JT-Shop: right
03:49 PM jym: JT-Shop: Any reason not using IR motion sensor instead?
03:50 PM JT-Shop: at least this one the label is in chinglish the one I found on banggood was chinlee
03:50 PM JT-Shop: I just want to sense a vehicle with no false alarms
03:51 PM jym: Fair enough, I've had good results with IR sensors
03:51 PM XXCoder: jym: what is "solar down the road"?
03:52 PM JT-Shop: which IR sensor
03:52 PM jym: XXCoder: To put the system on solar power instead of mains.
03:52 PM XXCoder: ahh ok
03:54 PM gloops: this is a lot of technology for a fried egg lol
03:55 PM roycroft: solar installations tend to use higher voltages to keep down the cost of wiring, so one might not be able to power a 12vdc device directly from a solar array
03:55 PM jym: roycroft: Not directly, but via solar controller/battery
03:56 PM roycroft: it would still be easier to do than inverting
03:56 PM jym: "it" ?
03:56 PM roycroft: powering a dc device instead of an ac device
03:57 PM jym: There are 12VDC solar panels
03:57 PM gloops: i could do with some cheap solar power lights
03:57 PM jym: gloops: dollar store
03:57 PM gloops: i wonder what level of light chickens recognise as 'light'
03:57 PM roycroft: yes, and when arranged in an array they're generally wired in series to step up the voltage so that thinner wires can be used for transmission to the controller
03:58 PM gloops: jym like those shed LED lights?
03:58 PM jym: gloops: garden pathway
03:58 PM roycroft: it's common to install the panels in banks of four, and transmit 48vdc
03:58 PM gloops: i didnt think theyd run very long on a day long charge
03:59 PM Loetmichel: on german residental roofs its mor like 700VDC to the inverters
03:59 PM Loetmichel: more
03:59 PM Loetmichel: up to
03:59 PM jym: roycroft: Not so much these days. The have 300V panels now with mini controllers built into the panels, so reduces cost on using 12GA wiring instead of 4 or 2 ga
03:59 PM roycroft: the higher the voltage the smaller the wire required, and the less transmission loss
04:00 PM roycroft: ok
04:00 PM roycroft: 48vdc used to be commone
04:00 PM roycroft: common
04:00 PM roycroft: it appears things have changed for the better now
04:00 PM Loetmichel: [22:58] <Loetmichel> akku65: was für ne strangspannung haben deine solaranlagen?
04:00 PM Loetmichel: [22:59] <akku65> Ömmm, 350V $oderso
04:00 PM jym: roycroft: They still exist
04:00 PM Loetmichel: he says his systen has 350V per row of panels down to the inverters.
04:00 PM jym: roycroft: ...just costly to wire
04:01 PM roycroft: yes, i read that
04:01 PM Loetmichel: and 700V are not unheard of.
04:01 PM Loetmichel: 48V would be WAAAAY to high current at a few 10kW
04:01 PM Loetmichel: peak
04:02 PM gloops: only thing is my chickens dont have 1 shed, they can go in and out of 4 different ones
04:03 PM roycroft: a chicken villa!
04:03 PM gloops: they just roam about
04:04 PM roycroft: vagabonds
04:04 PM gloops: https://www.ebay.co.uk/itm/Solar-Powered-Outdoor-Garden-Patio-Decking-Hanging-Garage-Shed-LED-Lamp-Light/222682306249?
04:05 PM gloops: not powerful enough
04:11 PM gloops: anyway its the solstice tommorrow - longer daylight
04:12 PM jym: gloops: You must live south of the equator
04:13 PM gloops: no jym UK
04:13 PM JT-Shop: yep longer days now each day
04:13 PM jym: hmmm, ok
04:13 PM jym: Didn't realize that, hasn't snowed yet
04:14 PM gloops: probably wont lay till march anyway
04:14 PM JT-Shop: gloops: how old are your hens?
04:15 PM gloops: JT couple of years most of them, 2 this years chicks
04:15 PM JT-Shop: no supplmental light?
04:15 PM gloops: no, no power on where they are
04:16 PM JT-Shop: from what I've heard the pullets will lay all winter cause they don't know better lol
04:16 PM jym: CLUCK POWER... IT'S THE FUTURE!!!
04:16 PM JT-Shop: mine are 18 weeks old today
04:17 PM gloops: hmm, some breeds are better than others, usually if we raise any from the spring, they wont lay till the following spring
04:17 PM gloops: what breed JT?
04:19 PM gloops: if theyre raised in ideal conditions, proper lighting, correct diet some are at POL at 16 week, usually more like 5 or 6 months
04:20 PM gloops: and if that coincides with winter as it usually does for naturally hatched, longer
04:20 PM JT-Shop: Rhode Island Red
04:21 PM gloops: id say 22 week
04:21 PM JT-Shop: the hatchery says 16-24 weeks, they have had 12.75 hours of light or more since the get go
04:22 PM gloops: ours just free range eating what they find, we also feed them scraps, bread and leftovers + wheat and layers pellets, you arent supposed to do that if you want them to lay like clockwork
04:23 PM gloops: RIR are nice birds though, probably the best
04:23 PM JT-Shop: I feed mine 18% starter and a bit of wheat fodder I grow
04:24 PM JT-Shop: when they start laying I'm switching to 18% all flock and having oyster shells on the side I think you guys call it soluble grit
04:24 PM gloops: ahh you want to get proper layers mix to get them going
04:26 PM JT-Shop: the layer is the same as all flock but with added calcium added, my rooster if he lives that long don't need the extra calcium from layer
04:27 PM gloops: we generally up the diet when theyre coming into lay, feeding them pure factory pellets - the eggs dont taste good though, you can mix it 1 pellets to 2 wheat without production dropping much
04:27 PM gloops: and the eggs are a lot better
04:27 PM JT-Shop: they get a cup of wheat sprouts a day with the feed
04:28 PM JT-Shop: http://gnipsel.com/images/chickens/fodder/fodder-rack-05.jpg
04:28 PM gloops: lol
04:29 PM JT-Shop: http://gnipsel.com/images/chickens/fodder/fodder-rack-04.jpg
04:29 PM JT-Shop: try that one
04:29 PM gloops: i think mine would be classed as feral at the side of those
04:30 PM JT-Shop: yea mine have lived a sheltered life so far
04:30 PM JT-Shop: time for me to snuggle with Sweet Pea while everyone else does the time to roost dance
04:35 PM * jym never knew that JT-Shop was such a princess sleeping on a pea under his mattress(es) ;)
04:36 PM Deejay: gn8
04:47 PM roycroft: chickens love to eat spent grain from brewing
04:47 PM roycroft: and it's really good for them
04:47 PM roycroft: if you can find a local microbrewery who have to dispose of their spent grain you might be able to get heaps of free chicken food
04:49 PM gloops: a lot of people are going on about the wonders of feeding chickens yogurt here
04:49 PM gloops: does wonders for laying apparently, ive given mine the odd dollop but not tried it properly so cant say
04:49 PM roycroft: that would be expensive
04:50 PM roycroft: unless you also have cows and make your own yoghurt
04:50 PM gloops: i dont know how much a big carton of natural yogurt is now, maybe £2 a pint
04:56 PM gregcnc: 2 for 1 crashes? https://youtu.be/kKTQh9CXvx8?t=9s
05:40 PM anonnumberanon: lol does anyine use water to lubricate metal drill and cut?
05:41 PM anonnumberanon: this guy claims it's good for stainless steel
05:42 PM JT-Shop: my coop just sent me an email saying the door is closed lol
05:44 PM MarcelineVQ: :>
05:46 PM gloops: water is ok for drilling
05:46 PM JT-Shop: well it sent me two one saying it's in motion, one saying it's closed
05:47 PM gloops: music might help them get laying
05:51 PM gloops: https://www.dailystar.co.uk/news/latest-news/357694/Chickens-lay-more-eggs-when-listening-to-soothing-classical-music
05:52 PM anonnumberanon: haha
05:56 PM gloops: water doesnt lubricate, it cools
05:57 PM gloops: many cutting scenarios need lubricant as well as coolant
05:57 PM gloops: like soluable oil
05:58 PM anonnumberanon: lol this guy teaches how to use a square while tapping but it's only square in one axis, heh https://www.youtube.com/watch?v=X9VhONdGFFg&t=9m01s
05:59 PM anonnumberanon: would probably always use one of those guides to tap to do a good job, or a drill press..
05:59 PM * anonnumberanon learns the drill press tap technique next
05:59 PM MarcelineVQ: anonnumberanon: some recent tap talk here if you're interested https://www.youtube.com/watch?v=HJn9rSzAKEE
06:00 PM MarcelineVQ: drill press mean putting a tap-follower in the press?
06:00 PM MarcelineVQ: *meaning
06:01 PM anonnumberanon: yeah im look at what to do with my (chrismas soon to be mine) 10" drill press for tapping
06:01 PM gloops: you cant beat hand tapping i dont think
06:01 PM gloops: well, if you dont mind the work
06:01 PM gloops: only takes a minute
06:01 PM anonnumberanon: i heard you can just turn the chuck by hand but what is that tap-follower sweetness you are mentioning?
06:01 PM MarcelineVQ: neat, what's the quill travel on that press?
06:01 PM anonnumberanon: i think 2 inches
06:01 PM anonnumberanon: if you mean how far down it can go with the lever
06:02 PM MarcelineVQ: a tap follower is a spring-loaded pin basically that keep the tap stright while you turn it by hand
06:02 PM anonnumberanon: gloops, wouldn't it be absolutely straight if you use a drill press?
06:02 PM MarcelineVQ: it goes in the dimple on the top of taps
06:02 PM * anonnumberanon shops for that
06:02 PM gloops: anon they dont wander much - they have to follow the hole
06:03 PM MarcelineVQ: they can wander enough to break teeth :(
06:03 PM gloops: maybe for a shallow tap
06:03 PM gloops: Marcel starter tap in hard stuff
06:03 PM anonnumberanon: nothing about tap followers on amazon.com..
06:04 PM MarcelineVQ: yeah though that quickly adds up when you're buying two taps for every job hehe
06:05 PM MarcelineVQ: anonnumberanon: if you'r alergic to google, they can also be called tap guides though that's not the name I see more often https://www.amazon.com/Brown-Sharpe-599-792-30-Adjustable-Tensioned/dp/B005317ZMC
06:05 PM MarcelineVQ: https://www.youtube.com/watch?v=y79op3DM4uo
06:06 PM gloops: i suppose it depends, im messing about with 5ft lengths atm, too much trouble to move it
06:07 PM MarcelineVQ: anonnumberanon: If you can get more than 2" quill travel you should, mine is 2" and I am constantly constantly fighting for room to work
06:07 PM anonnumberanon: oh i already ordered it
06:08 PM anonnumberanon: the price was right, I'll upgrade maybe
06:08 PM Tom_L: do it once and do it right
06:08 PM anonnumberanon: it's not too hard to sell tools on craigslist i can get my money back if i start to really struggle with it
06:11 PM anonnumberanon: Tom_L, don't forget to document how to align things please that's like my strongest doubts about your cnc, i don't doubt it i doubt how i would do it so really interested to see how you do it.
06:12 PM Tom_L: i took part of it out to my bud's today to have machined
06:12 PM anonnumberanon: yay, will it be finished today?
06:12 PM Tom_L: the parts that won't fit anything i've got
06:12 PM Tom_L: no
06:12 PM anonnumberanon: he must have a large strong machine to be able to machine your steel frame
06:13 PM Tom_L: he used to have a shop full of large cnc's and manual ones
06:13 PM anonnumberanon: will he machine the bottom where it meets the bench/floor/legs as well as the top where you will put your rails or what?
06:13 PM Tom_L: now he's retired but kept one cnc, bridgeport and a nice lathe etc
06:18 PM Tom_L: i wonder what size drag chain i should get for this
06:19 PM anonnumberanon: so he's machining the bottom and the top of your frame?
06:20 PM Tom_L: i haven't taken that part out there yet but he probably will
06:25 PM anonnumberanon: circular saw arriing tomorrow so ill be able to make a workbench quickly
06:25 PM anonnumberanon: Tom_L, he will probably be very happy to do this for you.
06:25 PM anonnumberanon: like perfectly and stuff
06:25 PM Tom_L: we trade favors
06:25 PM anonnumberanon: i would
06:26 PM anonnumberanon: what do you do for him?
06:26 PM Tom_L: mostly computer stuff
06:26 PM Tom_L: keeping his cnc up and goin
06:28 PM anonnumberanon: haha there you go nice exchange of skills
06:29 PM Tom_L: i could do the work, just don't have the machines to do it
06:29 PM anonnumberanon: when i used to fix my friends' cars it only went one way :(
06:30 PM Tom_L: 18 x 25 should be big enough...
06:32 PM anonnumberanon: I'm gonna need a 20mm by 20mm table for my cnc. One that's less than 1 thousandth accurate on all dimensions
06:32 PM anonnumberanon: 200 by 200 i mean
06:35 PM anonnumberanon: does this look like a good beginner kit?

06:39 PM archivist: bearing steel is a bit odd for taps and dies
06:45 PM Tom_L: i generally just get the taps i need
06:47 PM Tom_L: same with reamers
06:47 PM Tom_L: i did get a decent 115 piece drill set though along with an every day one i keep replacing bits in
06:55 PM Tom_L: BeachBumPete did you get your dimension issue figured out?
06:57 PM anonnumberanon: MarcelineVQ, i see what you mean about the spring loaded center, this is really nice
06:59 PM anonnumberanon: oh wait no not as nice as i thought
06:59 PM anonnumberanon: just good for the beginning or something
06:59 PM anonnumberanon: won't stay on there for the entire tap operation since the drill press chuck will stay immobile and not go down with the tap
06:59 PM anonnumberanon: wait, spring-loaded...
06:59 PM anonnumberanon: humm..
07:00 PM MarcelineVQ: well, you lower what's holding it when you run out of spring travel
07:00 PM MarcelineVQ: in a deep enough hole you're well lined up at a certain point as well

07:01 PM Tom_L: that's the one i've got
07:01 PM MarcelineVQ: that's not what we're talking about but those are wonderful, I used mine to start holes in thin walled tubing recently
07:01 PM Tom_L: oh, for centering a hole?
07:02 PM MarcelineVQ: he's talking about tap followers/guides
07:02 PM Tom_L: ok
07:03 PM MarcelineVQ: Tom_L: I inherited a sterret version of that unit, they're lifesavers
07:13 PM anonnumberanon: oh yeah i've ordered a punch already
07:14 PM anonnumberanon: any video you can link about cnc tables? the main surface you attach things to, and that you use to square the machine?
07:15 PM anonnumberanon: machine table base they are called?
07:16 PM anonnumberanon: there is this but i'm assuming my machine would need to be squared BEFORE doing this.. heh chicken and egg
07:18 PM anonnumberanon: I'm having a really hard time getting info on this. Most tables are not the dimensions I need and the ones Ebay has that I have found so far go to $100 to $150 in average.
07:20 PM MarcelineVQ: it's not quite like lego some things you'll need to make or modify instead of buy as-is
07:22 PM anonnumberanon: so what to buy that's already very precise and true to be able to square the rest around it?
07:22 PM BeachBumPete: Tom_L no I just posted it in a 3d view and another file with a drawing template showing the dimensions I needed
07:23 PM Tom_L: it's not a feature you would use that often really
07:23 PM BeachBumPete: actually I do that most often with these parts
07:24 PM Tom_L: i'm not sure if SW has that feature but i know catia does
07:25 PM BeachBumPete: I think you can do it in SW because that is where I recall doing it but its been awhile since I had SW access
07:44 PM Connor: Anyone point me to a good VFD for 1.5HP Motor for my bridgeport?
07:46 PM anonnumberanon: I could buy 16 of those to make my own table, that would be 80 dollars.
07:46 PM anonnumberanon: http://www.orangealuminum.com/t-slot-framing-systems-and-tracks/t-track.html
07:46 PM anonnumberanon: it seems to have 10 to 20 thousandth of tolerance ..
07:55 PM Tom_L: pretty light weight
07:56 PM Tom_L: my bud has gotten away from using T slots for fixture plates
07:57 PM Tom_L: he's got an aluminum plate bolted to his table that literally looks like swiss cheese
07:57 PM Tom_L: a variety of different size holes to acomodate different fixture mounts
08:05 PM jdh: Connor: I have this bookmarked. not sure why. http://dealerselectric.com/variable-frequency-drive-motor-control.asp
08:06 PM Connor: https://www.amazon.com/LAPOND-Inverter-Professional-Frequency-VFD-2-2KW/dp/B01DKJWM6W
08:06 PM Connor: Looking at this one..
08:07 PM Jeebiss_ is now known as Jeebiss
08:10 PM Connor: Only issue I see with using a VFD is having it output RPM vs Frequency... Not sure if it can do that..
08:11 PM jdh: http://a.co/iC8XL3A
08:12 PM jdh: this one does modbus http://a.co/89diDjg
10:13 PM trentster: Anyone know if where in the docs it explains how to add a seperate tab in ngcgui to add buttons for routines like center finding etc?
10:15 PM Tom_L: http://linuxcnc.org/docs/2.7/html/gui/ngcgui.html
10:16 PM trentster: Thanks Tom_L
10:20 PM jesseg: Interesting, it says Bone ash is used in machine shops for various purposes. https://en.wikipedia.org/wiki/Bone_ash#Machining
10:20 PM jesseg: Anyone ever heard of that before?
10:25 PM trentster: If I want to use the same pin I am using for auto z touch off plate to use for hole finding routine would what I have added in this custom_postgui.hal suffice? line 36 is all I've added.
10:27 PM trentster: https://pastebin.com/t9jBvzi1
10:28 PM trentster: and I've added the routine to my "routines" directory, its called p-hole.ngc
10:34 PM Tom_L: probably something around 33
10:35 PM Tom_L: err, that's not a pin
10:36 PM trentster: isnt the pin defined in the main "hal" file?
10:36 PM trentster: e.g. I see this in my main hal file:
10:36 PM Tom_L: unless it's around 40 and beyond
10:36 PM trentster: "net deb-probe-in debounce.0.0.in <= parport.0.pin-11-in-not"

11:45 PM trentster: If anyone can help, I'd sure appreciate 5 minutes of time.
