12:00 AM unterhaus: turned out the 250A circuit breaker was computer adjusted to only be something like 50a
12:06 AM unterhaus: I knocked out the power for half the building once, then the electrician did it again
12:06 AM unterhaus: I like the idea of being able to adjust breakers like that
12:06 AM unterhaus: but they had to bring a computer over and wire to the breaker, not sure about wifi
12:06 AM unterhaus: the only good news about that was the electrician was walking through our building when I blew the breaker
12:06 AM unterhaus: could have been hours before they fixed that
12:19 AM unterhaus: Tom_L feeding the troll over on devel
12:19 AM unterhaus: ^was

12:27 AM roycroft: well, now i remember why i never finished that rpi project
12:27 AM roycroft: i need some screws that i don't have, and do not want to even think about making
12:32 AM unterhaus: what kind of screws?

04:07 AM JT-Cave: morning
04:07 AM XXCoder: hey timeoutboy
04:08 AM JT-Cave: must be sun spots my internet is flaky
04:34 AM andypugh: Chickens are hogging the bandwidth wathinv Wallace and Grommit on YouTube
04:34 AM XXCoder: yeah likely
04:34 AM XXCoder: training for their own eventual rebellation
04:34 AM XXCoder: make them into chicken pies NOW
04:35 AM XXCoder: too bad chickens are smat to cut off internet to ward off warnings
04:43 AM -!- #linuxcnc mode set to +v by ChanServ
04:45 AM -!- #linuxcnc mode set to +v by ChanServ
04:46 AM andypugh: Hey, JT, While you were out we decided that it’s the Chickens that are messing with yout internet while they plot a chicken uprising.
04:47 AM XXCoder: yeah I recommand pie thing
05:24 AM -!- #linuxcnc mode set to +v by ChanServ
05:28 AM JT-Cave: quite likely they are a devilish bunch
05:29 AM XXCoder: indeed
05:39 AM JT-Cave: every time I flash a sd card with etcher it hijacks .html files and next time I try and open one etcher is the app wtf
05:39 AM XXCoder: thats weird
05:52 AM jymmmm: Morning
05:53 AM XXCoder: yo
05:53 AM jymmmm: What's "etcher" ?
05:53 AM XXCoder: program to flash sdcard or whatever with image
05:53 AM jymmmm: ah
05:53 AM XXCoder: normally its very easy to use. jts having oddissue
05:54 AM jymmmm: gotcha
05:54 AM XXCoder: JT-Cave: all html files on your computer, or it replaces html files im image with etcher?
05:55 AM jymmmm: XXCoder: I think he means when he clicks on a html file, etcher is opening it instead of a browser.
05:55 AM Tom_L: morning
05:55 AM XXCoder: yeah more likely
05:55 AM XXCoder: hey tom
05:55 AM jymmmm: Morning Tom_L
05:56 AM XXCoder: JT-Cave: you can change it back i dont remember how to do it on windows though
05:56 AM jymmmm: haha, neither do I at the moment
05:56 AM JT-Cave: windows?
05:57 AM XXCoder: linux should be simple enough using context menu
06:02 AM JT-Cave: yea but etcher keeps changing it back lol
06:02 AM XXCoder: man that is weird
06:06 AM jymmmm: JT It looks like it might have been infected... https://forums.balena.io/c/etcher/32
06:07 AM jymmmm: Primarily windows, but who knows.
06:07 AM JT-Cave: yea I don't use it on windblows
06:09 AM XXCoder: i looked though git of etcher for html
06:09 AM XXCoder: no result
06:10 AM jymmmm: JT I understand that, but if infected, etcher could be trying to inject JS malware into html files
06:13 AM JT-Cave: etcher just complains that something is missing and I close it, the files are not changed
06:15 AM jymmmm: "etcher is Made with JS, HTML, node.js" ugh
06:17 AM JT-Cave: time to be a Chicken Tender
06:17 AM XXCoder: time for chicken pies
06:21 AM _unreal_: yawn
06:21 AM _unreal_: wow yesterday I was sooooooo wiped out I didnt wake up till noon
06:21 AM _unreal_: I guess I'm caught up a bit
06:21 AM _unreal_: now
06:22 AM jymmmm: IT's annoying when the downloads don't include a SHA1 to verify
06:24 AM XXCoder: expecially if its critical like driver or os update
06:25 AM jymmmm: exactly
06:32 AM Tom_L: socal still playin with the light switch?
07:37 AM tiwake: I keep changing my mind from getting one of these https://www.artcotools.com/compete-nsk-e3000-series-spindle-system-60-000-rpm.html
07:38 AM tiwake: to just using a stepper motor to rotate a wedge cutting tool to face the direction of the cut
07:40 AM tiwake: merf
07:41 AM tiwake: anyone have any favorite CNC kits?
07:44 AM JT-Cave: XXCoder, etcher replaces the file association in caja so when I click on a .html file etcher pops up and complains that the header is missing
07:46 AM tiwake: for that matter, how much does that NSK cost anyway?
07:52 AM tiwake: https://www.ebay.com/itm/Nakanishi-Modular-NR-3060S-Spindle-w-EM-3060-Motor-E3000-Series/313258540485?hash=item48efa9fdc5:g:f1sAAOSwnwpfTqUo that seems like a good price
08:43 AM tiwake: neh, I want something that spins fast
08:53 AM Tom_L: what do you plan to cut with it?
08:54 AM tiwake: mainly engraving, but I think it would be fun to be able to do 3D milling
08:54 AM Tom_L: wood aluminum and plastic?
08:54 AM tiwake: donno what materials
08:55 AM tiwake: maybe other stuff too
08:55 AM Tom_L: high speed spindles kinda limit what you can cut without work hardening etc
08:55 AM gregcnc: do the math with your available feed rates and expected feed per tooth
08:55 AM tiwake: sure
08:58 AM tiwake: Tom_L: do you have a favorite place to get CNC kits?
08:58 AM Tom_L: no, i built my own
08:58 AM gregcnc: https://www.ebay.com/itm/263174089090 these must be fairly new I didn't see any decent looking brushless DC spindles last tiem I looked
08:59 AM gregcnc: i wonder if they're any good
08:59 AM tiwake: the one I want to get goes up to 60k RPM... heh
09:00 AM Tom_L: that's kinda scary
09:00 AM Tom_L: you need good tooling for those speeds
09:00 AM gregcnc: https://www.ebay.com/itm/263174081107
09:00 AM tiwake: https://www.ebay.com/itm/Nakanishi-Modular-NR-3060S-Spindle-w-EM-3060-Motor-E3000-Series/313258540485?hash=item48efa9fdc5:g:f1sAAOSwnwpfTqUo
09:00 AM Tom_L: any imballance and the tool will be a missle
09:01 AM tiwake: NSK is top tier stuff
09:01 AM Tom_L: i know that
09:01 AM gregcnc: well 3mm shank carbide is pretty decent
09:01 AM Tom_L: i'm also talking about cutters
09:01 AM gregcnc: NSK are nice
09:01 AM tiwake: oh, sure...
09:01 AM Tom_L: you don't usually see quality stuff like that pop up here :)
09:02 AM Tom_L: at least on the 'noob' scale
09:02 AM tiwake: shit I should just get that spindle
09:02 AM tiwake: the one I linked
09:02 AM gregcnc: 1/8" and smaller carbide end mills are readily avaialble and cheap
09:02 AM Tom_L: yeah
09:02 AM gregcnc: even good stuff
09:02 AM tiwake: for that I'd use maritool
09:02 AM tiwake: they make good shit
09:03 AM gregcnc: maritool doen'st make any cutters
09:03 AM tiwake: endmills
09:03 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/etching/mills1.jpg
09:03 AM Tom_L: those were ~$20 ea
09:04 AM Tom_L: online carbide and lakeshore seem to have nice carbide
09:04 AM gregcnc: how much is a driver for the NSK?
09:05 AM tiwake: donno, I'm only looking at ebay
09:05 AM tiwake: https://www.ebay.com/sch/i.html?_from=R40&_nkw=NE211&_sacat=0&rt=nc&LH_PrefLoc=1
09:05 AM Tom_L: tiwake, i would hesitate on that one. says used and on those rpm you definitely want good bearings
09:05 AM tiwake: Tom_L: right, there is no new NSK things on ebay
09:05 AM tiwake: I don't know how much new costs
09:06 AM gregcnc: all that stuff is pricey
09:06 AM Tom_L: i don't think quality companies sell ebay
09:06 AM CaptHindsight: only 350W so the driver should not be much
09:06 AM gregcnc: sure they do
09:06 AM tiwake: here is the kit https://www.artcotools.com/compete-nsk-e3000-series-spindle-system-60-000-rpm.html
09:06 AM tiwake: from some random company in califorina
09:07 AM tiwake: I've used that spindle system before, its very nice
09:07 AM gregcnc: I think new they run 3kUSD
09:07 AM tiwake: very quiet
09:08 AM gregcnc: maybe a bit less. https://www.maxprod.com/products/nsk-9775.asp
09:08 AM tiwake: is there a cheaper but still really good competitor to that?
09:09 AM tiwake: $2k for the controller... merf
09:10 AM CaptHindsight: https://www.ebay.com/itm/NSK-NAKANISHI-E3000C-Control-Unit-Model-NE211-and-Cables-/124121112967
09:10 AM CaptHindsight: was only $400
09:10 AM gregcnc: either you take your chances with ebay or auction hunt this stuff costs real money
09:11 AM CaptHindsight: https://www.ebay.com/i/293582805347
09:12 AM Tom_L: the big ones run ~$70k
09:12 AM Tom_L: 40-50 taper
09:13 AM CaptHindsight: not a big market
09:13 AM CaptHindsight: and shops just plug and pay
09:13 AM Tom_L: just about every shop across the country have em
09:14 AM Tom_L: yeah plug in pay for sure
09:14 AM CaptHindsight: but if you know how these things work you can save $$$$
09:15 AM tiwake: well, there are no guarantees in life to begin with...
09:16 AM gregcnc: if you have the time to screw around, you can do that. bigger companies rarely do
09:17 AM tiwake: you know what I kind of want to do
09:18 AM CaptHindsight: shops rarely have engineers and usually not electrical
09:18 AM tiwake: get a big steel plate, and just drill and tap 1/4-20 holes every inch or so and use that for the bed of the CNC mill that I'll be building
09:18 AM CaptHindsight: big co's have other problems
09:19 AM tiwake: and not move the bed around, instead moving the cutter
09:19 AM tiwake: 3' cube of bed
09:20 AM gregcnc: what kind of parts require that?
09:20 AM tiwake: donno
09:20 AM tiwake: any kind that I decide to make
09:20 AM gregcnc: 3' of styro foam?
09:21 AM tiwake: wut
09:22 AM gregcnc: 3' cube of aluminum weighs how much?
09:22 AM CaptHindsight: http://www.airturbinetools.com/spindles/app_case_studies/flying_s.html
09:23 AM CaptHindsight: https://www.ibagnorthamerica.com/ibag-spindles-applications
09:23 AM tiwake: why would I be machining a cube of aluminum?
09:23 AM CaptHindsight: https://www.moldmakingtechnology.com/articles/why-you-should-use-high-speed-machining-with-micro-tooling
09:25 AM Tom_L: tiwake, why not? http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube/Cube2.jpg
09:25 AM gregcnc: big parts generally require big machines
09:25 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube/Turners_cube2.jpg
09:25 AM tiwake: CaptHindsight: https://www.ibagnorthamerica.com/ibag-spindles-small-spindles
09:26 AM tiwake: Tom_L: I mean, sure, but not 3'x3'x3'
09:26 AM tiwake: thats... pretty huge
09:26 AM Tom_L: that big one is about that size
09:26 AM gregcnc: three feet? milled on the sherline right?
09:26 AM Tom_L: oh no, 3"
09:26 AM Tom_L: sry misread
09:27 AM Tom_L: most of the parts my kids machine are loaded with a crane though
09:27 AM Tom_L: so yes
09:27 AM tiwake: one of Tom_L's eyes wasen't working
09:27 AM gregcnc: and those machines are how big?
09:28 AM Tom_L: yeah
09:28 AM Tom_L: they're big
09:28 AM tiwake: CaptHindsight: how much do you think those cost?
09:29 AM tiwake: I don't think I need faster than 60k RPM... heh
09:29 AM Tom_L: i can't imagine why
09:29 AM Tom_L: unless you're running production
09:30 AM CaptHindsight: pricing is usually similar to other brands, the only bargains are brands that cut corners and lose quality
09:30 AM tiwake: even production
09:31 AM tiwake: oh, how does linuxCNC interact with the mesa controller boards?
09:31 AM CaptHindsight: look at your application closer
09:31 AM tiwake: does it feed something like Gcode to them?
09:32 AM tiwake: CaptHindsight: I just wanna make money with the machine
09:32 AM gregcnc: you need a pretty good idea of what you'll be doing with it
09:33 AM Tom_L: tiwake, you'd have to ask peter about that
09:34 AM Tom_L: or look at the source
09:34 AM CaptHindsight: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?EMC_Components
09:34 AM Tom_L: pretty sure it's below the gcode level though
09:34 AM CaptHindsight: g-code is at one end and the Mesa boards at at the other
09:34 AM tiwake: engraving and probably cutting 3D sculptures out of various materials
09:35 AM gregcnc: will roughing with an 1/8"x1" tool be adequate?
09:35 AM gregcnc: especially if there is 3" to deal with?
09:35 AM gregcnc: dah, 3 feet
09:36 AM tiwake: for a bed that size I would likely keep various fixtures set
09:36 AM tiwake: more space is more better
09:36 AM CaptHindsight: haha "htasta> aaaw guys you really blew it. he woulda given us world piece and all you had to do is give him a CNC."
09:36 AM tiwake: I don't think I would be using all of that space at the same time
09:38 AM gregcnc: how does 3' of Z travel come into play?
09:38 AM Tom_L: large gantry
09:39 AM tiwake: did I say 3' for Z? maybe... donno how much Z I actually want
09:39 AM gregcnc: 3' cube you said
09:39 AM Tom_L: i wish i had a little more now
09:39 AM Tom_L: by the time you get fixtures etc you lose alot of z
09:40 AM tiwake: or oddly shaped parts
09:40 AM tiwake: say castings or something... iunno
09:40 AM gregcnc: how many machines built like this? that aren't 5 axis
09:40 AM tiwake: horizontal mills are I think
09:43 AM gregcnc: all I'm saying is think it through if you really need to work on parts that large If you look at teh machine that do that kind of work they are either huge or 5 axis
09:44 AM gregcnc: or both
09:44 AM Tom_L: keep in mind, the more axis the more expensive the cad cam
09:44 AM Tom_L: as well
09:45 AM Tom_L: 4 & 5 axis are alot more common place now than when i was doing it though
09:45 AM tiwake: 4 axis is pretty simple... more or less
09:45 AM tiwake: most of them time all 4 axis are not moving at the same time
09:46 AM tiwake: a 5th though, lots of things are made with all 5 axis moving
09:48 AM gregcnc: i don't know what your expectations are, just don't underestimate requirements of the machine
09:49 AM tiwake: I mean, whatever machine I have I can find work for
09:50 AM tiwake: for heavier duty stuff I need three phase power though, which will cost about $10k just to string the power lines
09:50 AM tiwake: and however much more to actually get it installed in my small shop
09:51 AM gregcnc: phase converter?
09:51 AM tiwake: those cost about 10k too
09:51 AM gregcnc: how much power do you need?
09:51 AM tiwake: say I get a haas VF2 or something
09:52 AM tiwake: and a lathe
09:52 AM tiwake: heh
09:52 AM tiwake: it adds up quick
09:53 AM tiwake: the 220 single phase I have is not beefy enough to power it anyway
09:53 AM gregcnc: yeah power is always a consideration with industrial machines
09:54 AM gregcnc: only 100A service?
09:54 AM tiwake: 60amp is what is installed
09:54 AM tiwake: breakers
09:55 AM tiwake: donno if it can handle more with bigger breakers
09:55 AM Tom_L: on my friend's first vmc he swapped out the transformer so he could run it in his garage
09:55 AM Tom_L: after that he started using a phase inverter
09:56 AM Tom_L: finally just had 3 phase brought in
09:56 AM tiwake: tl;dr I'm looking at lower power things that would be good for engraving or cutting/nibbling out sculptures
09:56 AM tiwake: but still not be cheaply built
09:57 AM gregcnc: but a 2.2kW spindle is a long way from 2 20HP machines
09:57 AM Tom_L: yeah
09:57 AM tiwake: what?
09:57 AM CaptHindsight: you have only 12HP or 9200 watts available for everything at 70% derating
09:58 AM gregcnc: engraving spindle vs VF2 and similar size lathe
09:58 AM tiwake: sure, I don't need three phase for the NSK stuff
09:58 AM tiwake: why would I?
09:59 AM gregcnc: I use a phase perfect can't complain
09:59 AM CaptHindsight: you have enough power to run a small office and some power tools
10:00 AM tiwake: https://www.maritool.com/Cutting-Tools-End-Mills-Ball-End-Mills-2-Flute-Spherical-Ball/c78_79_119_582/p18464/.1575-Spherical-Ball-End-Mill-220deg-2-Flute-TiAlN-Coated-.79-LOC/product_info.html
10:02 AM gregcnc: heh that's Harvey's dimensional sketch
10:06 AM tiwake: hmm
10:06 AM tiwake: looks like if I buy used from ebay, end up spending about $1500 or so
10:11 AM tiwake: https://www.ebay.com/itm/Nakanishi-E3000C-NE211-Spindle-CNC-Controller-Driver-High-Speed/302940068254?hash=item4688a2999e:g:vRkAAOSw5atb2J3x
10:12 AM tiwake: ships from USA, not thailand
10:19 AM tiwake: Tom_L: do you think 3'x3' is a good size for a bed? or should it be bigger?
10:19 AM tiwake: and how much Z should I build?
10:21 AM gregcnc: what is your work holding? what are your parts? what kind of tooling? as travels increase the structure has to increase
10:22 AM Tom_L: my cube is 17.75 x 13 x 7"
10:23 AM Tom_L: you will want more z for sure
10:23 AM Tom_L: x and y aren't quite as critical since all the tooling and fixtures eat up z
10:23 AM gregcnc: it sounds like you want o build a Datron
10:24 AM tiwake: what is that?
10:24 AM Tom_L: if you're doing 3d you will want more for sure
10:24 AM tiwake: Tom_L: are you using steppers or servos?
10:24 AM Tom_L: consider rotary too, that raises the z up
10:25 AM Tom_L: steppers: 570 in/oz
10:25 AM tiwake: hmm
10:25 AM gregcnc: https://www.youtube.com/watch?v=3YzAl29Ag78
10:26 AM gregcnc: how much axis thrust do you have Tom?
10:28 AM CaptHindsight: veegee: what is wrong with you canucks? https://www.cbc.ca/news/canada/montreal/quebec-city-police-stabbings-1.5785401
10:28 AM CaptHindsight: you're supposed to use a gun!
10:31 AM Tom_L: tiwake, https://www.ebay.com/itm/3pcs-NEMA23-570OZ-IN-5A-3-8-DUAL-SHAFT-STEPPER-MOTOR/253223632606?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649
10:31 AM Tom_L: with gecko 203v drivers
10:32 AM tiwake: that seems... small
10:32 AM Tom_L: plenty beefy for me
10:32 AM Tom_L: i cut some steel on mine
10:33 AM Tom_L: i have yet to stall them
10:33 AM tiwake: I was thinking about getting one of these https://www.automationtechnologiesinc.com/products-page/servo-nema34-kits
10:33 AM gregcnc: direct drive?
10:33 AM Tom_L: mine are
10:33 AM gregcnc: screw pitch?
10:33 AM Tom_L: z is 3:1 though
10:33 AM Tom_L: 5mm
10:35 AM Tom_L: https://www.ebay.com/itm/US-20mm-Square-linear-guide-400-700-1000mm-RM1605-Ballscrew-BKBF12-f-CNC-Router/402520657974?hash=item5db819d036:g:Sz0AAOSw-u9fmnnT
10:35 AM Tom_L: those
10:39 AM gregcnc: tom on the direct drive axis you have 1100lb thrust.
10:39 AM Tom_L: should be more than enough for what i do
10:39 AM gregcnc: far more
10:39 AM Tom_L: i wasn't sure at the time so i did the reduction on z
10:40 AM Tom_L: i have pulleys to go 2:1 as well
10:40 AM Tom_L: i see no reason to change them though
10:41 AM Tom_L: incicentally, my spindle motor is out for delivery today
10:41 AM gregcnc: what kind of motor did you get?
10:41 AM Tom_L: 1.2kw BLDC 5600 rpm
10:42 AM Tom_L: so i'll either do 1:1 or 1: 1.15 to get around 6400 rpm
10:42 AM gregcnc: that should be fun
10:42 AM Tom_L: i still gotta order pulleys for it
10:43 AM Tom_L: i'm waiting to mount it to get the center distance for the belt length
10:59 AM _unreal: well thats interesting. just looked up a computer I got from the dumpster at work this past week. its an other euro computer
11:00 AM _unreal: got to love the luxury yachts
11:05 AM Loetmichel: *shudder* just got my new passport/ID in the mail Why do have Pictures on official ID always be so bad?
11:19 AM t4nk_freenode: lol
11:20 AM t4nk_freenode: well... I got the same thing, Loetmichel ... but I'm quite sure it's because I am in them :|
11:26 AM jymmmm: Loetmichel: Not bad, just your natural beauty shining thru
11:30 AM JavaBean: atleast you didn't break the camera. they seem to have gotten more robust in the last 20 years
11:30 AM Loetmichel: ... or it may have to do with the fact that the picture was taken by a computerized system that ordered a specific pose juuust after sprinting for 1 mile from the parking lot to the town hall to meet my appointment... ;)
11:30 AM JavaBean: nah, you natural looks
11:32 AM t4nk_freenode: Looksmichel
11:33 AM t4nk_freenode: also; they're valid for 10years now in europe.. so enjoy it for a while ;)
11:33 AM t4nk_freenode: oh, and one more thing... the next one..
11:34 AM t4nk_freenode: will always be worse than the last one.
11:35 AM JavaBean: you aren't wrong
11:35 AM roycroft: our dmv offices are still closed
11:35 AM roycroft: i don't know how people get new driving licenses these days
11:35 AM roycroft: renewals are done via mail
11:35 AM JavaBean: since when have people in the us needed a "license"
11:36 AM roycroft: i think they're just sending temporary paper license that needs to be used with the expired picture license
11:36 AM pfred1: you need a license to operate a motor vehicle on a public road
11:36 AM roycroft: my tabs just expired
11:37 AM roycroft: when i renewed them i got a letter back from the state saying there's an inventory shortage of tabs, and not to expect them until the end of december at least
11:37 AM roycroft: and they sent me a temporary permit to attach to my rear window
11:38 AM roycroft: it seems odd that they would have a shortage of tabs
11:38 AM roycroft: unless the tab printing place has printing presses that are touching each other so that workers cannot safely operate them
11:39 AM pfred1: tab works funny in my client
11:40 AM roycroft: tab is being discontinued again
11:40 AM t4nk_freenode: what do you mean by tab?
11:41 AM roycroft: in the most recent context, a very untasty sugar-free cola bevarage
11:41 AM roycroft: beverage
11:41 AM pfred1: I meant the key
11:42 AM roycroft: the tab key in my client is a hotkey for privmsg, and pressing it repeatedly scrolls through the names i've privmsg'ed since launching the client
11:43 AM t4nk_freenode: then I'll be speaking of sensasionalist journalism
12:10 PM unterhaus_: pennsylvania got rid of the date stickers on license plates. So cue the stories of Pennsylvanians being pulled over in other states
12:11 PM unterhaus_: already have a problem because we don't have front plates
12:11 PM pfred1: Pennsyltuckey seems to have a lot of problems
12:18 PM _unreal: ok
12:18 PM _unreal: powering up
12:24 PM unterhaus_: anyone can recommend a low-cost variable bench power supply?
12:28 PM pfred1: unterhaus_ do you rent or own your own home?
12:30 PM pfred1: the power that can come out of a recepticle is awe inspiring
12:31 PM pfred1: I had an electrician tell me once that you can see 50,000 amps before a breaker kicks off
12:36 PM Rab: See how?
12:36 PM Rab: Like a disturbance in the Force?
12:37 PM gregcnc: maybe if it's a breaker at the substation
12:39 PM unterhaus_: pfred1, if you are saying I shouldn't get a cheap psu that will be dangerous, I assume nobody would recommend such a thing
12:39 PM unterhaus_: Except CaptHindsight
12:39 PM _unreal: ok so working on going though the config again
12:39 PM _unreal: the
12:39 PM pfred1: unterhaus_ electronics is like the wild west it is hard to tell when you're riding into town if it is going to go well or not
12:40 PM gregcnc: I haven't shopped for PSU in a long time isn't it just about power rating?200W vs 2kW?
12:40 PM _unreal: 7i96 config tool. OR should I use the lcnc setup/config tools?
12:40 PM pfred1: gregcnc power rating is certainly one metric
12:40 PM _unreal: I could also use a hand on dbl checking my math
12:40 PM _unreal: so my setup
12:40 PM gregcnc: the one you start with
12:40 PM pfred1: but today you have to worry about mains isolation too
12:40 PM _unreal: 1.8 degree stepper motors
12:41 PM _unreal: 1/8th stepping
12:41 PM pfred1: because PSUs have fundamentally changed
12:41 PM _unreal: my machine has pulleys, 10 tooth at the motor to 48 tooth,
12:41 PM pfred1: SMPS as opposed to ballast transformers
12:41 PM _unreal: driving threaded rod 13 TPI
12:42 PM pfred1: there's PSUs made now where one output is directly connected to the mains
12:43 PM unterhaus_: I assume you have stuck your tongue into one to test it
12:43 PM _unreal: 200 step motor 1/8th stepping is 1600 micro steps, 48 teeth / 10 teeth=4.8 turns per rotation,
12:43 PM pfred1: _unreal you use all thread lead screws?
12:43 PM _unreal: yes
12:43 PM _unreal: with HDPE nuts
12:43 PM _unreal: lasts for ever
12:43 PM Rab: unterhaus_, I'd stick to at least a quasi-namebrand. I think KORAD is one. The no-name stuff can look identical, like it came off the night shift of the same production line, but people have done teardowns and some are really poorly made and dangerous.
12:43 PM roycroft: _unreal: if you use pncconf you shouldn't have to check your math, or even do any math
12:43 PM _unreal: very little resistance and NO BACK LASH
12:43 PM pfred1: I burnt out an HDPE nut with acme thread
12:43 PM pfred1: but i was running it 2,000 RPM
12:43 PM roycroft: you plug your parameters into the configuration wizard and it will do the work for you
12:44 PM _unreal: heh ya that may have some issues
12:44 PM Rab: pfred1, what was the failure mode? Did the threads melt?
12:44 PM pfred1: it did
12:44 PM _unreal: I'm not sure what RPM I'll get
12:44 PM pfred1: Rab it stripped it out
12:44 PM _unreal: pfred1, I did a test few days ago running 4000mm/m back and forth for about 30min
12:44 PM pfred1: made the machine run funny was a bit of a hassle to diagnose what was actually going on
12:44 PM _unreal: no heating
12:45 PM Rab: Exciting. I've used Delrin with pretty good luck, but at low speeds.
12:45 PM _unreal: then again I grease the shit out of the rod with white lithium
12:45 PM _unreal: the drive nuts I hand built and are sectional and 4" long
12:45 PM roycroft: this is frustrating
12:45 PM gregcnc: you don't need any microstepping at all with the low pitch and that reduction
12:45 PM _unreal: 3" sorry
12:45 PM roycroft: i'm trying to buy a 55 gallon barrel off cl
12:46 PM roycroft: the seller doesn't want to deal with me unless i text him
12:46 PM roycroft: which i can't do
12:46 PM _unreal: roycroft, if you lived near me I could get you tons of them
12:46 PM _unreal: we go though 55gal drums all the time
12:46 PM roycroft: he says he's paranoid about giving me his address or any other contact info via email
12:46 PM roycroft: and insists on texting
12:46 PM Rab: roycroft, how does he propose to get the barrel to you?
12:46 PM gregcnc: some thign weren't meant to be
12:46 PM roycroft: i told him i could call him or he can call me
12:46 PM roycroft: or he can meet me somewhere if he doesn't want to tell me where he lives
12:47 PM roycroft: he keeps telling me to text him to prove i'm not a spammer
12:47 PM roycroft: he wants me to text him, rab, and he'll text his address back to me
12:47 PM roycroft: somehow that "proves" that i'm real in a way that email ortelephony cannot
12:47 PM pfred1: roycroft why do you need to know his address?
12:47 PM gregcnc: last time I dealt with CL the guy sent me his address before I even asked
12:47 PM _unreal: roycroft, I've never used pnconfig
12:47 PM roycroft: i don't
12:47 PM roycroft: i jsut want to buy a barrel from him
12:48 PM roycroft: i would need his address to pick it up
12:48 PM Rab: roycroft, why can't you text?
12:48 PM roycroft: because i can't
12:48 PM _unreal: ?
12:48 PM _unreal: you dont have a cell phone?
12:48 PM roycroft: i do
12:48 PM gregcnc: he's just as frustrated you can't text
12:48 PM roycroft: but it has sms disabled by the carrier
12:48 PM t4nk_freenode: he just never learnt to type
12:48 PM _unreal: roy just use google
12:48 PM _unreal: you can send SMS via google
12:48 PM pfred1: nice
12:49 PM _unreal: google phone something like that. its been awhile
12:49 PM roycroft: there's another seller who wants me to call him
12:49 PM roycroft: but when i do the recapcha thing on cl it always gives me an "internal error" popup
12:49 PM roycroft: and i never see the guy's phone number
12:49 PM roycroft: i've told him this in email, and he responds to email
12:49 PM Rab: Most carriers have SMS gateways, too. But I expect those would show up as something weird, only heightening scammer suspicion.
12:49 PM roycroft: but he wants me to call to arrange the pickup
12:50 PM roycroft: and wants me to get the number off cl
12:50 PM pfred1: I had a website not work the other day until after i clicked away the cookie message
12:50 PM _unreal: what is "use INI substantiations for mesa board names?
12:50 PM roycroft: how do people sell stuff if they are this difficult?
12:50 PM pfred1: I was just ignoring it
12:50 PM gregcnc: they probably don't
12:50 PM pfred1: not everyone is Amazon
12:50 PM roycroft: _unreal: pncconf is recommended by several folks here
12:51 PM roycroft: i would use it to generate a configuration
12:51 PM roycroft: then review the hal files it generates
12:51 PM _unreal: and I'm asking
12:51 PM roycroft: there's a mesa config section
12:51 PM _unreal: WHAT.. is "use INI substatutions for mesa board names
12:51 PM _unreal: its one of the first page check options
12:52 PM roycroft: i don't recall seeing that
12:52 PM roycroft: i haven't run pncconf in a long time
12:52 PM _unreal: its the first page
12:52 PM roycroft: i'll be doing it again soon, but not this minute
12:52 PM _unreal: I dont know what its for what it does
12:52 PM _unreal: I'll leave it blank then
12:52 PM roycroft: i'm sure someone like jt or andypugh would be able to tell you
12:52 PM roycroft: leave it blank if you can
12:53 PM roycroft: as i said, you generate the configuration with it
12:53 PM roycroft: then review the files it generates
12:53 PM roycroft: so you have an opportunity to fix/tweak things
12:53 PM _unreal: test base period
12:53 PM _unreal: its defaultin to 100,000 what am I looking for for a value to enter?
12:54 PM _unreal: max servo is around 12,000, base thread around 24,000
12:56 PM _unreal: ok few copys of glxgears running and other stuff running and servo=25,200 base 38,200
12:57 PM _unreal: then again I'm using mesa card
12:57 PM rs[m]: _unreal: you want only one thread, and this should have 1ms
12:57 PM rs[m]: period
12:58 PM rs[m]: _unreal: that would be 1000000 (1mio) ns
12:58 PM _unreal: so leave it at default?
12:59 PM rs[m]: _unreal | its defaultin to 100,000
12:59 PM rs[m]: so, no
12:59 PM _unreal: its set to 1,000,000
12:59 PM rs[m]: but in all probability the default is 1000 000
12:59 PM _unreal: by default
12:59 PM _unreal: ns
01:01 PM _unreal: onto the next page
01:01 PM _unreal: general GUI
01:01 PM _unreal: position offset, and feed back settings
01:03 PM _unreal: offset= machine or relative
01:03 PM _unreal: feedback= commanded or actual
01:08 PM _unreal: arg... online info is lite when it comes to these options
01:09 PM _unreal: default liner velocity, mini vel, max vel
01:09 PM _unreal: angular
01:10 PM t4nk_freenode: angular schmengular
01:11 PM roycroft: i guess what i fundamentally don't understand is why so many people are so paranoid and protective of their email addrss, yet hand their cell phone number out to anyone in the world without a second thought
01:11 PM roycroft: myself, i'm the opposite
01:11 PM roycroft: i'm extremely protective about giving out my phone number
01:12 PM t4nk_freenode: can I have it?
01:12 PM roycroft: if i'm at all concerned about giving out an email address i just make one up for the person in question
01:12 PM _unreal: email providers sell your email address
01:12 PM roycroft: and nuke it if spam starts arriving
01:12 PM _unreal: same with phone companies. so why that guy is paranioed is moronic
01:13 PM roycroft: i actually do the same thing with my phone number when i feel the need to give it out randomly
01:13 PM roycroft: such as when i'm selling stuff on cl
01:13 PM _unreal: chances are you could get that guys SS number if he's in the usa for $25
01:13 PM roycroft: i have a voip service, and costs me $1.50 to get a new phone number
01:13 PM roycroft: it's worth that much if i'm going to publish it on cl for stuff i'm selling
01:13 PM roycroft: perhaps i'm odd
01:13 PM roycroft: well, i know i'm odd
01:14 PM roycroft: but when i sell stuff i try to make it as easy as i can for folks to communicate with me
01:14 PM roycroft: i don't see the point in making it all but impossible to do so
01:15 PM roycroft: but i get this all the time from sellers "i am not going to give you my email address, but here's my cell phone number"
01:17 PM roycroft: i know many folks can't make up a new email address as easily as i can, but still, if you have privacy concerns, don't give out your cell number to random people
01:18 PM roycroft: i'm going to try to get the other seller's phone number using a windows-based browser, in case the error i get is a javascript thing
01:18 PM roycroft: i really want to get a barrel today
01:19 PM roycroft: the windows machine does not even give me the phone link
01:20 PM roycroft: i think cl is broken
01:23 PM t4nk_freenode: it sure is keeping you up and busy
01:23 PM roycroft: well i need to get this asap
01:24 PM roycroft: to the point that if there were a local vendor who sold them brand new i'd pay the $100 for a new one
01:25 PM t4nk_freenode: vs how much on cl?
01:26 PM roycroft: $20
01:26 PM roycroft: i'd rather pay $20
01:26 PM roycroft: but i just need to get one
01:26 PM t4nk_freenode: hehe, no kidding ;)
01:26 PM roycroft: it's holding up a project
01:32 PM roycroft: you must text me guy finally agreed to meet me somewhere
01:32 PM roycroft: what a pain in the butt
01:34 PM _unreal: god this is confusing but I got motion with the mesa
01:34 PM _unreal: doing the test setups testing the drives and tuning
01:35 PM _unreal: very glad I'm using 1/8th micro stepping. 1/2 was a bit choppy
01:35 PM t4nk_freenode: lol, where's the meat, and when is it going down, roycroft?
01:35 PM pfred1: microstepping runs smoother
01:35 PM pfred1: you should see how a stepper motor runs on a sine wave
01:36 PM pfred1: like butter i have a 120V stepper motor runs right off wall current
01:36 PM t4nk_freenode: you'll still need to be able to cut through sth thicker than butter though
01:36 PM pfred1: you need to phase shift one of the coils
01:37 PM pfred1: can do that with a capacitor
01:38 PM pfred1: http://i.imgur.com/L0AMzq8.jpg
01:38 PM roycroft: he wants to meet at a garden center :)
01:38 PM roycroft: fortunately it's not far from my house
01:40 PM t4nk_freenode: he're probably robbing some swimming pool as we speak ;)
01:40 PM t4nk_freenode: he's.
01:40 PM pfred1: that whole bank of capacitors is in series so it makes one cap
01:40 PM pfred1: my pool died
01:42 PM andypugh: _unreal: Probably too late, but “use INI ….” means that the HAL contains lines like “net signal 1 [HOSTMOT2]BOARD.0.input.001” instead of “net hm2_5i25.0.input.001”
01:43 PM andypugh: So, if you later change the Mesa card you only have to change one INI line to change all the HAL. But I think it looks untidy and don’t use it.
01:43 PM _unreal: so DOO dont use it
01:43 PM _unreal: lol
01:47 PM andypugh: Before PNCCONF it was very useful for the sample Mesa configs, as they could be made to work with different cards with little editing. But if you are using Pncconf, if you got a different card you would probably just run it again.
01:48 PM _unreal: it moves
01:49 PM _unreal: in LCNC
01:49 PM _unreal: now to test limit switches
01:49 PM _unreal: is there an area where I can see limit switch activitiy?
01:49 PM _unreal: before I crash into them i'd like to know if they are functioning
01:49 PM _unreal: my machine kind of has like 2k lbs torque
01:49 PM _unreal: forces
01:49 PM _unreal: thing
01:51 PM pfred1: I just use soft limits
01:51 PM pfred1: we don't need any stinking limit switches
01:52 PM andypugh: I have learned my lesson. for this 4th prototype of a bracket thinkgy I am only 3D printing one of them, rather than 12 before a trial fit.
01:53 PM _unreal: hum
01:53 PM _unreal: ok homing in the wrong direction and limits do not seem to be working
01:53 PM _unreal: tried a homing and manualy tapped the limits
01:54 PM _unreal: so they are ether not wired right or not programmed right
01:54 PM t4nk_freenode: doa from the truck I'm afraid :|
01:54 PM t4nk_freenode: again!
01:55 PM jymmmm: Shit, no wonder I keep thinking it's later than it is... time changed last night
01:55 PM t4nk_freenode: hehe... been a while alrady
01:56 PM _unreal: ????
01:57 PM _unreal: ARE THE 7i96 inputs suposed to get tied to ground ?
01:57 PM _unreal: or are you suposed to feed them 5v?
01:57 PM _unreal: they now testing apear to be +5v at the pins ??????
01:58 PM _unreal: but everything I've found on line says +5v to limit switch to INPUT on 7i96
01:58 PM pcw_home: 7I96 inputs depend on how the input common is connected
01:58 PM _unreal: so WTF?
01:58 PM _unreal: ?
01:58 PM renesis: are they bipolar optos?
01:58 PM renesis: bipolar optos are <3
01:58 PM _unreal: renesis, its a 7i96
01:58 PM pcw_home: if the input common is ground you need +4V to +24V in the inputs
01:59 PM renesis: sounds like an old gpu to me
01:59 PM _unreal: pcw_home, I'm reading 5.11v on the inputs. and 5.25 if the limit is triggered. the 5v supply is 5.25
01:59 PM jymmmm: _unreal 11 isolated inputs provided for general control use including limit switch and controlpanel inputs. Inputs operate with 4V to 36V DC and can have a positive or negativecommon for sourcing or sinking input applications. Six 36V 2A isolated outputs allowsinking, sourcing combinations of both.
01:59 PM _unreal: so I'm guessing I need to tie the inputs to ground?
02:00 PM _unreal: the board on the inputs has a common
02:00 PM pcw_home: if the input common is +4V to +24V, you ground the inputs to activate
02:00 PM renesis: they are bipolar inputs
02:00 PM renesis: <3
02:00 PM _unreal: is that a setting?
02:00 PM _unreal: or
02:00 PM _unreal: design?
02:00 PM tiwake: Tom_L: do you think I should go with stepper motors instead of servos?
02:00 PM renesis: its just two opto diodes in inverse parallel config
02:00 PM renesis: thyey spent they extra nickel
02:00 PM pcw_home: its up to you (how you connect the input common pin)
02:01 PM jymmmm: Nickle?! Cheap bastards :D
02:01 PM renesis: pcw_home: how many inputs per common?
02:01 PM _unreal: just put the metter
02:01 PM pcw_home: all on a 7I96 (in various groups on other cards)
02:01 PM _unreal: and common reads 5v if I probed the right now
02:01 PM renesis: could be more <3
02:01 PM _unreal: right one
02:02 PM pcw_home: you have to connect the input common to ground or +V
02:05 PM renesis: _unreal: you might be reading leakage currents or something, put the meter down and find a schematic if you want to understand
02:06 PM _unreal: ?
02:06 PM _unreal: pcw_home, as in jump common to a ground jumping a wire?
02:06 PM _unreal: using a jumper wire
02:06 PM _unreal: ?
02:06 PM renesis: have an EE at work alwats putting ohm meter across everything, pisses me off, his DMM prob like WTF
02:07 PM renesis: three phase mains? lets put an ohm meter on it
02:07 PM pcw_home: Yes, if you want active high inputs, wire input common to ground. if you want active low inputs, wire input common to V+
02:07 PM jymmmm: renesis: better than a cap meter
02:08 PM renesis: jymmmm: :(
02:08 PM renesis: the other day he wired his cabinet up funk and it didnt turn off when he switched it off
02:08 PM renesis: i still havent gotten an explanation on that
02:08 PM _unreal: is there a link you can show me on line
02:08 PM renesis: so he ohm meters everything, I FOUND THE PROBLEM GUYS
02:09 PM renesis: EARTH AND NEUTRAL ARE CONNECTED
02:09 PM renesis: and im like, dotdotdot
02:09 PM _unreal: because that makes no god damn sense?
02:09 PM renesis: _unreal: sec
02:09 PM renesis: tho im guessing the documents have a schematic
02:09 PM jymmmm: renesis: Hey, at least he didn't say neutral and hot are connected
02:10 PM tiwake: jymmmm: what do you think? steppers or servos?
02:10 PM _unreal: jump a wire from common to ground on the board?
02:10 PM renesis: i dunno then at least i could have probably figured out wtf he did with his power switch
02:10 PM jymmmm: tiwake: for?
02:11 PM renesis: _unreal: https://i.stack.imgur.com/mzoMa.jpg
02:11 PM tiwake: for a 3'x3'x2' (or so) CNC mill
02:11 PM tiwake: scratch build
02:11 PM renesis: so how it has LEDs going both ways?
02:11 PM jymmmm: tiwake: motor size?
02:11 PM _unreal: I'm trying to get the limit switches wired. i have 0-5 wired to XYZ +/- limits
02:11 PM renesis: that makes it bidirectional, works DC+, DC-, AC
02:11 PM tiwake: jymmmm: something like this https://www.artcotools.com/compete-nsk-e3000-series-spindle-system-60-000-rpm.html
02:12 PM renesis: so there are a bunch of those connected on one side, the common side
02:12 PM _unreal: so +5v source to all 6 limit switches, and other end tied to 0-5 for +/- x +/- y ETC...
02:12 PM renesis: if you connect common side to voltage, ground turns the inputs on
02:12 PM renesis: if you connect the common side to ground, voltage turns the inputs on
02:12 PM _unreal: eheh thats an opto the link you posted
02:12 PM _unreal: I'm looking for a wireing schematic SHOWing how to wire the 7i96
02:13 PM jymmmm: tiwake: not spindle motor, drive/axis motors
02:13 PM renesis: i just explained how sink/source commons work
02:13 PM renesis: make your own schematic
02:13 PM _unreal: https://forum.linuxcnc.org/media/kunena/attachments/24949/WWK2xKP.png
02:13 PM _unreal: for example
02:13 PM _unreal: that is how its wired right now
02:13 PM _unreal: +5v to limit switch and other wide of limit tied to input
02:14 PM _unreal: but inputs are all HIGH apparently
02:14 PM _unreal: so ether I need to set the setting to invert in pnconfig
02:14 PM tiwake: jymmmm: donno... what should I get? was thinking about one of these https://www.automationtechnologiesinc.com/products-page/servo-nema34-kits
02:14 PM tiwake: heh
02:14 PM rs[m]: _unreal: what is "C" connected to
02:14 PM _unreal: right now nothing
02:14 PM _unreal: and it its self is +5v
02:14 PM jymmmm: tiwake: where are you on the planet?
02:14 PM renesis: ha, 7i96 doesnt have an input schematic
02:15 PM tiwake: I'd like to get inch ballscrews too, but I don't know where to find them
02:15 PM renesis: _unreal: see you have to make your own
02:15 PM tiwake: jymmmm: Texas
02:15 PM _unreal: o,O
02:15 PM renesis: wtf nothing
02:15 PM _unreal: own?
02:15 PM rs[m]: _unreal: connect C to the ground of whatever powers your limit switches
02:15 PM renesis: yes your own
02:15 PM _unreal: renesis, exactly
02:15 PM renesis: unterhaus_: do what rs[m] says
02:15 PM renesis: the way you have it wired its not supposed to work
02:15 PM _unreal: so jump a wire from common to any ground
02:15 PM renesis: gimme a sec i can find you a schematic for something similar
02:15 PM _unreal: god that is fucking retarted
02:16 PM renesis: what?
02:16 PM rs[m]: _unreal: look at the C at the schematic you posted
02:16 PM renesis: pcw_home: _unreal is mean :(
02:16 PM _unreal: interesting
02:16 PM _unreal: had not noticed that
02:16 PM _unreal: ? god thats freaking weird
02:17 PM _unreal: no resistors?
02:17 PM renesis: he put resistors for you
02:17 PM renesis: https://cdn.automationdirect.com/static/specs/c002dd2d.pdf
02:17 PM _unreal: ok...
02:17 PM _unreal: tieing to ground
02:17 PM renesis: page 1 has a schematic of similar setup
02:18 PM renesis: see you can flip the power supply either way so it works with whatever type of sensor outputs
02:18 PM renesis: its kind of like magic, only really it is 2x the LEDs
02:19 PM _unreal: ok rebooting mesa
02:19 PM renesis: i kinda dont like how they did the diode symbols in that
02:19 PM renesis: it almost looks like a triac
02:20 PM renesis: https://i.stack.imgur.com/mzoMa.jpg
02:20 PM renesis: definitely sexier symbols
02:20 PM _unreal: ahh
02:20 PM _unreal: sigh
02:20 PM _unreal: how to I reactivate networking?
02:20 PM _unreal: had to shut down the card
02:20 PM _unreal: err entire everyting to mess with the wiring
02:21 PM _unreal: ok just did an MM test
02:21 PM _unreal: and all the limits are low
02:22 PM _unreal: and hitting the limit set it high
02:22 PM _unreal: but I need to start up networking again
02:22 PM renesis: so it works!?
02:22 PM _unreal: I'm going to assume so
02:22 PM _unreal: need to re-establish network connection
02:22 PM renesis: i mean its bidir optos how does it not work
02:23 PM _unreal: systemctl restart networking
02:23 PM _unreal: ok networking back up
02:23 PM _unreal: ok limit works but its homing in the wrong direction
02:24 PM _unreal: for Y axis
02:24 PM _unreal: testing x
02:24 PM _unreal: Z I cant do anything with
02:24 PM _unreal: doesnt exist
02:24 PM renesis: slap it
02:24 PM _unreal: ok x and y are going in the wrong direction
02:25 PM _unreal: so is that an INV setting? in the pnconfig?
02:26 PM renesis: or you can swap some wires
02:26 PM _unreal: mother fucker this is confusing.??? ok now GPIO settings that were grayed out before for the TB3 are now active?
02:27 PM _unreal: I'm guessing thats because I grounded COM?
02:27 PM _unreal: heh..
02:27 PM renesis: thats pretty neat that it knows
02:27 PM _unreal: thats just it I have made to many chances to know if doing one thing or an other was what did it?
02:27 PM renesis: guess you will never know unless you start undoing things one at a time
02:28 PM _unreal: now its listing them as
02:28 PM renesis: i say you just throw your hands in the air (and wave them like you just dont care) and move forward
02:28 PM _unreal: pin type, GPIO INPUT, gpio output, gpio O drain
02:29 PM rs[m]: ALWAYS change at least 3 things at once before looking for any effects
02:29 PM _unreal: heh
02:29 PM renesis: rs[m]: !
02:29 PM _unreal: I'm in the pnconfig
02:29 PM _unreal: rs[m], right now I'm trying to figure out how to change the homing direction
02:29 PM _unreal: the machine moves in the correct directions for control
02:30 PM _unreal: the limit switches for HOME area are working but its seeking to the wrong direction
02:30 PM rs[m]: i don't know pncconf, but probably you need to make the search velocity negative
02:30 PM renesis: is your g53 going to be negative or positive?
02:31 PM _unreal: g53?
02:31 PM renesis: just curious, i have no advice but i might call you a weirdo
02:31 PM _unreal: god I've used planetcnc for to long
02:31 PM renesis: wow _unreal you have been here for probably 15 years abd your going to "g53?" at me?
02:31 PM _unreal: very powerful but makes a lot of options simplified
02:32 PM renesis: g53 is machine space, or machine coordinates, or machine workspace, or non user workspace, or whatever you want to call it
02:32 PM renesis: its non modal in gcode
02:32 PM Tom_L: tiwake, it's your call but steppers work fine for me
02:36 PM _unreal: in the pnconfig it has a choice for twards neg/pos limit
02:36 PM _unreal: it is set for neg. already
02:36 PM _unreal: and the neg limits worked to activate the homing BUT it was traversing in the positive direction
02:37 PM renesis: so maybe it means negative workspace home limit
02:38 PM renesis: i would think that would be the default, but its kind of a machine builders preference
02:39 PM renesis: personally, when i see positive G53 coordinates i am like, cnc heathens
02:40 PM W1N9Zr0: http://linuxcnc.org/docs/2.7/html/config/ini-homing.html#_homing_sequence
02:40 PM _unreal: and typing - negative number when the drop down choice is negative would be kind of odd
02:40 PM _unreal: not to mention conflictin easy
02:40 PM _unreal: hehe
02:40 PM W1N9Zr0: if your homing switch is inverted, the machine will start moving in the back off direction instead of the homing direction
02:41 PM renesis: oh thats cool you can set it to home at switch make or break i guess
02:41 PM renesis: because it thinks its already there
02:41 PM _unreal: no index pulse
02:41 PM _unreal: just a limit :)
02:42 PM * t4nk_freenode makes notes whilst he closely monitors _unreal @work
02:43 PM t4nk_freenode: always humbling to be able to observe a great master
02:43 PM t4nk_freenode: *shedding tear of joy*
02:43 PM roycroft: grr
02:43 PM renesis: omg dont encourage him
02:43 PM _unreal: just tears
02:43 PM t4nk_freenode: lol...
02:44 PM t4nk_freenode: oh
02:44 PM roycroft: i waited for the guy for a half hour and he never showed up
02:44 PM t4nk_freenode: hehe I thought y..
02:44 PM t4nk_freenode: indeed
02:44 PM * t4nk_freenode rubs his eyes..
02:44 PM _unreal: at least the mesa is driving the motors remaining working motor controllers
02:45 PM _unreal: once I get the limits setup then I'm "" home free ""
02:45 PM t4nk_freenode: yeah, I wanna be right there at that moment :))
02:45 PM t4nk_freenode: with my stopwatch :b
02:46 PM t4nk_freenode: mmm I oughtta get on with my power supply I guess... but I'm too happy it's finally got all them friggin wires inside
02:46 PM t4nk_freenode: and staying inside
02:49 PM roycroft: maybe i should start a new website - craigslist for grownups
02:50 PM _unreal: hum
02:55 PM _unreal: stil going in the wrong direction
02:56 PM _unreal: tried setting neg numbers
02:56 PM _unreal: funny how it goes away from the home switch
03:01 PM roycroft: you can switch the direction in your configuration file
03:01 PM roycroft: or, if you're using 3 phase steppers, swap two of the pairs of wires
03:01 PM t4nk_freenode: he just never responded anymore, roycroft?
03:01 PM roycroft: no
03:01 PM roycroft: i waited a half hour then went home
03:02 PM roycroft: because that's a good way to sell stuff
03:02 PM _unreal: I'm using standard steppers
03:03 PM t4nk_freenode: sjees... bummer
03:03 PM Lee_ is now known as Lee-
03:03 PM t4nk_freenode: I'm curious to what he'll say, if anything
03:03 PM _unreal: sigh, I'm just makin "" lunch for my daughter and I"" my father called and siad he may need me to get him from the hosptial hours ago. and he has not called....
03:04 PM _unreal: i was expecting to get mcdonalds
03:04 PM _unreal: sigh
03:05 PM _unreal: roycroft, where whould i find that in the settings?
03:05 PM _unreal: file
03:08 PM roycroft: i don't know offhand but i know it's there
03:08 PM roycroft: search for "invert"
03:09 PM _unreal: arg.. there is no GUI text editor. need to install one
03:09 PM pfred1: nano isn't so bad
03:17 PM Deejay: gn8
03:21 PM roycroft: nano isn't a gui editor, but it's curses/terminfo based
03:21 PM roycroft: and probably pretty easy for the novice to navigate
03:22 PM roycroft: i guess i need to move on to a different project this afternoon, since the barrel isn't happening
03:23 PM roycroft: time to try to find some m2.5-0.45 taps for the next project
03:23 PM roycroft: because i love stabbing at windmills
03:24 PM jymmmm: again?
03:25 PM roycroft: i have a don quixote complex
03:28 PM CaptHindsight: roycroft: I ordered a few sets off Amazon from ~1mm- 3mm
03:28 PM CaptHindsight: just to have around
03:29 PM CaptHindsight: the suppliers around here wanted $20ea
03:31 PM pfred1: roycroft why does an editor have to be GUI?
03:31 PM W1N9Zr0: m2.5 on a pi? just drill it out to 3mm
03:32 PM _unreal: I use nano all the time but there are times when you need a GUI
03:32 PM _unreal: more powerful features
03:33 PM renesis: fuck nano
03:34 PM renesis: vim < *
03:34 PM W1N9Zr0: nice one
03:34 PM pfred1: renesis it is better than vi
03:34 PM renesis: wait i fucked that up
03:34 PM renesis: anyway some nano installs have jacked up default configs
03:34 PM pfred1: I'm not BIll Joy
03:35 PM renesis: word wrapping saves come to mind
03:35 PM renesis: vut id rather vim than most gui text editors on lunix
03:36 PM renesis: im not sure what more powerful features im missing out on
03:36 PM _unreal: ok still trying to figure out why its homing the wrong direction
03:36 PM renesis: are you using NO when it expects NC or something?
03:37 PM renesis: w1n9zr0's research seemed to make a lot of sense
03:37 PM rs[m]: _unreal: are you sure your axis is moving in the right direction?
03:37 PM renesis: he says yes
03:37 PM _unreal: yes
03:37 PM rs[m]: i would just check the other checkbox in pncconf
03:38 PM _unreal: if I press the + and set it to continu... it runs in the correct direction
03:38 PM _unreal: let me dbl check
03:38 PM veegee: CaptHindsight regarding medieval sword guy: LOL that's actually a case of mental illness
03:39 PM _unreal: oh shit.... dbl checking everyrthing
03:41 PM veegee: as opposed to the rampant gun violence in _other_ countries
03:42 PM renesis: guns is like anarchy, the people who want guns probably shouldnt be trusted with guns
03:43 PM renesis: like, on a philosophical level, anarchy and guns are great
03:46 PM CaptHindsight: veegee: I wish we took mental illness seriously down here
03:47 PM renesis: and education
03:47 PM renesis: and gun training
03:47 PM CaptHindsight: agreed
03:47 PM CaptHindsight: and sexual abuse
03:47 PM renesis: and child wellfare
03:47 PM renesis: and separation of religion and state
03:48 PM JavaBean: and the making of popcorn
03:48 PM renesis: but fuckit, celebrate stupidy and everyone gets a gun, woooooo
03:48 PM renesis: hor air popcorn ftmfw
03:48 PM CaptHindsight: the pageantry of stupidity
03:48 PM renesis: you can also roast coffee with same technology
03:49 PM JavaBean: i have a microwave popping bowl
03:49 PM renesis: sounds very dangerous
03:50 PM _unreal: ok I was looking at the machine backwards it is behind me
03:50 PM CaptHindsight: https://www.youtube.com/watch?v=611fw81BN98 Long Way Up, anyone else watch this?
03:50 PM renesis: dotdotdot
03:50 PM _unreal: homed x but it didnt pull off so
03:50 PM _unreal: got to get it set to the pull off level
03:51 PM CaptHindsight: they ride electric motorcycles 14k miles from the tip of South America to LA
03:51 PM JavaBean: yeah, maybe?? it might be polycarbonate, its marked #7(15)
03:51 PM CaptHindsight: support vehicles are also electric
03:53 PM renesis: capthindsight: neat
03:55 PM _unreal: use index pulse. are they talking about an encoder or the limit switch for detecting, backing off touching again?
03:56 PM _unreal: ?
03:56 PM roycroft: as i thought, i can get m3 fasteners locally, but not m2.5
03:57 PM roycroft: and even if i decided to go with american customary, i can get #4 fasteners, but not #3
03:57 PM _unreal: roycroft, I can get m2.5
03:57 PM roycroft: i am *not* going to spend the rest of the day making four tiny m2.5 screws
03:57 PM _unreal: there is a place in fort lauderdale called mconalds that sells everything
03:57 PM roycroft: i have other options tomorrow
03:57 PM roycroft: but that does not help me today
03:57 PM _unreal: small store but GOD they got evertyinhg
03:57 PM _unreal: they are " on paper " and ace hardware
03:57 PM _unreal: heh
03:58 PM _unreal: used m2.5's on my daughters machine for the pen holder I designed
03:58 PM roycroft: this is why i did not finish this project months ago
03:58 PM roycroft: i was missing four tiny screws
03:58 PM roycroft: and i'm still missing them
03:58 PM roycroft: now to move on to a project where i don't have to try to source any materials today
03:59 PM _unreal: heh
03:59 PM _unreal: ya the m2.5's were my PIA as well
04:00 PM JT-Shop: how can I test the onboard nic on this pc?
04:00 PM roycroft: this is to mount a rpi
04:00 PM roycroft: i can't go any bigger, even if i wanted to
04:00 PM roycroft: if i try to drill out the mounting holes to fit larger fasteners i'll damage the pcb
04:01 PM roycroft: i suppose i could hot glue it in place, but that's so eew
04:01 PM roycroft: jt-shop: loop it back to itself
04:01 PM jymmmm: roycroft: sub mounting plate
04:01 PM roycroft: no room
04:01 PM roycroft: it's a really tight fit
04:01 PM renesis: just buy screws and standoffs from mcmaster?
04:02 PM roycroft: and mcmaster will have them here in an hour on a sunday?
04:02 PM renesis: maybe
04:02 PM roycroft: they won't
04:02 PM roycroft: i promise
04:02 PM renesis: it is mcmaster
04:02 PM roycroft: i could get them by tuesday if i wanted to pay for overnight shipping
04:02 PM jymmmm: roycroft: silicone it
04:02 PM renesis: you should move to the LA area
04:02 PM roycroft: that's even more eew than hot glue
04:02 PM roycroft: i absolutely should not
04:03 PM roycroft: that would be horrible for me
04:03 PM roycroft: and horrible for la
04:03 PM jymmmm: roycroft: you want it bad, you get it bad. The worse you want it, the worse you get it.
04:03 PM renesis: think of all the same day mcmaster
04:03 PM roycroft: i just need to work on something else
04:03 PM renesis: standard ship costs!
04:03 PM roycroft: like the barrel i was supposed to pick up today
04:03 PM renesis: pew pew pew
04:08 PM JT-Shop: roycroft, thanks I'll look that up
04:12 PM roycroft: pin 1 to pin 3 and pin 2 to pin 6 will loop it back
04:13 PM roycroft: i just dug out a box of assorted fasteners that i haven't touched in like 20 years, and found exactly 2 m2.5-45 screws, that are 12mm long
04:13 PM roycroft: and i need 6mm
04:13 PM _unreal: boy this is agravating... still trying to get homing working
04:13 PM roycroft: but i can make those shorter :)
04:13 PM _unreal: its "working" but it homes. pulles off then goes back and just keeps going
04:13 PM roycroft: the board has four mounting holes, but 2 is enough to keep a rpi in place
04:14 PM roycroft: jt-shop: or you can just plug the built-in ethernet to a switch and see if you get link
04:14 PM rs[m]: _unreal: did you rtfm this http://linuxcnc.org/docs/html/config/ini-homing.html
04:14 PM JT-Shop: ok I'll try that
04:14 PM _unreal: roycroft, https://photos.app.goo.gl/GvprVxFfbKAWY7VR7
04:15 PM roycroft: i just 3d printed a case for the thing
04:15 PM roycroft: i have an ender 5 3d printer, and want to run octoprint to manage it
04:16 PM _unreal: roycroft, I figured you'd like the RPI "" shell ""
04:16 PM roycroft: i got a rpi4 for octoprint, and downloaded an enclosure that mounts the rpi right under the ender 5 control panel from thingverse
04:17 PM _unreal: rs[m] I've read that entire thing...
04:18 PM _unreal: rs[m], what is confusing is there are differences in what the PNCONFIG has for options to click on and what that page talks about
04:18 PM _unreal: they do not fully match up
04:18 PM roycroft: https://www.thingiverse.com/thing:4262878
04:18 PM roycroft: that's what i'm using
04:20 PM roycroft: i don't want a bunch of crap laying around, so mounting the pi inside the control panel enclosure is a pretty clean way of doing it
04:20 PM _unreal: home position location, home switch location. offsets I have yet to find a clear description of what they are and how they correlate
04:20 PM JT-Shop: https://dpaste.com/68F3WMQSZ looks like it's working
04:20 PM JT-Shop: hmmm
04:21 PM roycroft: _unreal: i'm not sure what your issue is, exactly
04:21 PM roycroft: but you can set your home position to be an offset from your home switch
04:21 PM roycroft: say you want to home almost at the absolute limit of an axis
04:21 PM _unreal: roycroft, right now it homes touches the switch, pulls off then goes back and just keeps going NEG
04:21 PM roycroft: but you can't mount your home switch right there, because you have a limit switch in the way
04:22 PM _unreal: I've for the hell of it tried switching home latch dir, from neg to pos and back and forth no change
04:22 PM roycroft: so you have to move your home switch 1" away from the limit of the axis
04:22 PM _unreal: ?
04:22 PM rs[m]: _unreal: did you turn on index pulse?
04:22 PM roycroft: you can do that, and then set an offset so that when you get to the home switch it moves that 1" back towards the limit
04:22 PM _unreal: I'm not moving my damn home switch
04:22 PM roycroft: and homes there
04:22 PM roycroft: i'm explaining what offsets are
04:22 PM _unreal: index pulse is for an encoder
04:22 PM _unreal: I do not have an encoder
04:22 PM roycroft: not telling you to move anything
04:23 PM _unreal: any more
04:23 PM roycroft: if you have an offset set that's what it's for
04:23 PM _unreal: I switched to the steppers
04:23 PM pfred1: I just tell my machine it is homed
04:23 PM roycroft: and if you want to home right at your home switch then you need to not set an offset
04:23 PM _unreal: roy I tried that
04:23 PM gloops: home offset i think
04:23 PM _unreal: it touched pulled off then went back and touched and errored that it was still on the switch
04:24 PM roycroft: that's fine, phred1, until you start doing a production run on a fixture plate
04:24 PM roycroft: you want a repeatable home for that
04:24 PM pfred1: the trick is home your machine before you turn it off
04:24 PM _unreal: ya I need a repeatable home
04:24 PM _unreal: I just want it to touch and pull off and done
04:24 PM gloops: so, first time it finds the switch at a steady speed (hopefully)
04:24 PM rs[m]: _unreal: look at latch velocity. does it have same sign as search velocity?
04:24 PM _unreal: non of this back and forth
04:24 PM pfred1: as long as you don't move it then it starts up homed
04:25 PM _unreal: rs[m], I've tried setting it to NEG and opposite and it still does the same thing
04:25 PM gloops: it then backs off the switch and returns to it, slowly to be very precise
04:25 PM _unreal: home latch direction
04:25 PM gloops: when its latched, it either stays there or you can set an offset for it to park it
04:25 PM roycroft: s/you don't move it/it hasn't moved/
04:25 PM _unreal: gloops, ya and it wont back off it again it hits it and tops and errors that its still touching the limit switch
04:26 PM _unreal: I set an offset and it tries to continu to go neg
04:26 PM pfred1: I also home in the center of the bed so if it is off a little no biggie
04:26 PM roycroft: indexing by trust is risky
04:26 PM _unreal: I dont have an index
04:26 PM roycroft: indexing by assumption even more so
04:26 PM gloops: you got the switch ..whats the term now
04:26 PM gloops: open live
04:27 PM gloops: few years sinc i did this
04:27 PM rs[m]: _unreal: latch vel should be opposite sign as search vel for what you want
04:27 PM gloops: someone will know
04:27 PM _unreal: rs[m], hehe I just said I have tried swtching that back and forth and it does not change
04:28 PM rs[m]: _unreal: are you sure
04:28 PM _unreal: yes
04:28 PM _unreal: ok currently set to
04:28 PM rs[m]: remember, always change at least 3 things at once
04:28 PM roycroft: does linuxcnc need to be restarted or sent SIGHUP after a change like that?
04:28 PM veegee: Why did they stop producing these? http://www.airtrax.com/photos.html
04:29 PM _unreal: ???????????????????????????????????/
04:29 PM _unreal: what in the blue hell
04:29 PM _unreal: I just changed it again and it touched pulled off and stopped
04:30 PM _unreal: same settings over and over switching direction
04:30 PM gloops: come on hows it work with limit switches, you need the circuit ....
04:31 PM gloops: im going to do a refresher on all this when my heads clear, in fact im building again next year
04:36 PM gloops: normally closed / normally open
04:49 PM _unreal: ok the machine is "" running the linuxcnc proram ""
04:49 PM _unreal: had to disable z limits since its not even rigged up
04:52 PM JavaBean: does that mean its beer time??
04:54 PM _unreal: taz have no beer :(*
04:54 PM JavaBean: :*(
04:55 PM JT-Shop: weird the nic is working now
04:55 PM pfred1: gotta love network issues
04:56 PM JT-Shop: not really lol
04:56 PM _unreal: uploading a video
04:56 PM pfred1: come on the problem could literally be anywhere in the world
04:57 PM JT-Shop: the problem can only be 1m from the nic at the most
04:57 PM _unreal: https://drive.google.com/file/d/1PMHFCbCGYkwsFH-tN91TG9Tb5LioR1MV/view?usp=sharing
04:57 PM JT-Shop: I flash Mesa cards with that nic and it's on 10.10.10.11
04:57 PM pfred1: I had a lightning storm blow a switch up here not too long ago
04:57 PM JavaBean: knowing poor jt, the problem is probably a PEBKAC type issue
04:57 PM pfred1: but i was due for an upgrade there anyways
04:58 PM JT-Shop: it's happened before
04:58 PM _unreal: pfred1, !!!! I'm going to take that to heart
04:58 PM pfred1: that old switch was literally from 1995
04:58 PM _unreal: going to put my entire machine behind APC
04:58 PM JT-Shop: we used to loose a lot of phone and computer equipment at the other shop till we drove more ground rods
04:58 PM _unreal: 10bt?
04:58 PM pfred1: 100
04:58 PM _unreal: in 95?
04:58 PM pfred1: I got GB now and it is nice
04:59 PM _unreal: ??? 100bt in 95???
04:59 PM pfred1: yes
04:59 PM JT-Shop: yea when I replace a switch it's GB
04:59 PM pfred1: 10/100
04:59 PM pfred1: we weren't living in caves in 95
05:00 PM JavaBean: speak for yourself
05:00 PM pfred1: OK not all of us
05:00 PM _unreal: you must have paid a fortune then
05:00 PM pfred1: it wasn't bad as i remember I got it at a warehouse
05:01 PM pfred1: somplace in Plainfield
05:01 PM pfred1: was an industrial park
05:01 PM pfred1: it wasn't CompUSA that's for sure
05:01 PM _unreal: hum
05:01 PM _unreal: well I have 2 ups's one has no batteries but its a very large one
05:02 PM _unreal: I'm going to setup one UPS for the computer and one for the machine
05:02 PM _unreal: that way at least its isolated
05:02 PM pfred1: I worked on a place that backed up financial data and they had a really large UPS
05:02 PM veegee: _unreal deep cycle lead acid is the way to go: https://www.solacity.com/product/rolls-surrette-s6-l16-hc/
05:02 PM pfred1: the battery room was the size of a basketball court
05:02 PM _unreal: shit I may need 3
05:03 PM pfred1: they just have shelving units of lead batteries
05:03 PM _unreal: my VFD for the 1.5kw spindle is rated at 13 amps
05:03 PM pfred1: then they had 3 diesel generators each the size of a freight locvomotive
05:03 PM pfred1: Google thinks the place is a law firm
05:04 PM _unreal: you guys look at the video?
05:10 PM roycroft: data centers like that used to use giant flywheels for backupk power
05:10 PM roycroft: cheaper and less maintenance than rooms full of batteries
05:10 PM roycroft: but way way scarier when something goes wrong
05:11 PM roycroft: they had generators behind the flywheels, of course
05:11 PM roycroft: the flywheels were just to keep the power on while switching over to generator power
05:13 PM _unreal: ???
05:13 PM _unreal: ok there is some funking weird shit going on with the controllers and speed
05:13 PM _unreal: I'm wondering if i should switch it back to half stepping
05:14 PM _unreal: trying to adjust JOG speed upto 700+
05:14 PM JavaBean: why not trying 1/4 stepping?
05:14 PM _unreal: I dont think I can
05:14 PM _unreal: there is no 1/4 listed
05:14 PM _unreal: fdm2740c
05:14 PM _unreal: if you can figure out the pulse rate that would be amazing
05:14 PM _unreal: err
05:15 PM roycroft: half step, mississippi uptown toodeloo
05:15 PM roycroft: hello baby, i'm gone goodbye
05:15 PM _unreal: setting for that pulse rate
05:15 PM roycroft: half a cup of rock and rye
05:15 PM roycroft: farewell to you old southern skies
05:15 PM roycroft: i'm on my way, on my way
05:16 PM t4nk_freenode: hehe... somehow.. cl seems like a fitting place to dwell for you, roycroft
05:17 PM _unreal: JavaBean, have you found a way to do 1/4 stepping?
05:17 PM _unreal: I dont get how it says 150khz
05:17 PM _unreal: for the drive but I cant even come close
05:18 PM JavaBean: no, sorry. i am trying to just be a lurker. i didn't know your setup doesn't do 1/4
05:19 PM _unreal: I cant seem to get much over 500mm/m before the drive pauses
05:19 PM _unreal: then again that could be timing as well
05:19 PM _unreal: in my settings
05:20 PM _unreal: I just chose gecko drive 202
05:20 PM _unreal: or something like that
05:20 PM _unreal: for timing settings
05:20 PM _unreal: the PDF for this motor controller doesnt give much info
05:22 PM _unreal: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwi-gKyovuLsAhUGS60KHdIJCZYQFjAAegQIBBAC&url=https%3A%2F%2Fkenswu.zzvps.com%2FFunction%2FManual%2FDS_FMD2740C_EN.pdf&usg=AOvVaw3jscG3nMKAlICnlFrmdShk
05:22 PM _unreal: JavaBean, I had a typo
05:23 PM JavaBean: oops
05:23 PM _unreal: FMD2740C
05:23 PM _unreal: fmd not fdm
05:23 PM _unreal: https://kenswu.zzvps.com/Function/Manual/DS_FMD2740C_EN.pdf
05:24 PM pfred1: _unreal looks fancy
05:24 PM _unreal: Min. impulse time 5 us
05:24 PM _unreal: uS
05:25 PM pfred1: Min. impulse time 5 us
05:25 PM pfred1: that's 5000 ns?
05:25 PM pfred1: now whether it can really handle its minimum is another matter
05:26 PM pfred1: to be safe you might want to go with 6000ns or so?
05:27 PM pfred1: I vageuly remember some issue with the pulse shape when I was setting LinuxCNC up
05:28 PM pfred1: you need an oscilloscope to check that out
05:29 PM pfred1: I was looking as scopes the other day you can get a lot of scope cheap these days
05:39 PM _unreal: I just adjusted the timing to 5uS
05:39 PM _unreal: the motors still stall if I go over 750mm/m
05:39 PM _unreal: though the other day when i was half stepping I was able to do 4000mm/m
05:39 PM _unreal: right now its set to 1/8th
05:39 PM _unreal: stepping
05:40 PM _unreal: well I'll be bacvk I have to go run. my daughter needs some supplies and my father JST @#$%@#$@#$@ called and is now ready to be picked up fom the hospital F..U...
05:40 PM _unreal: like magic always worst time
05:40 PM pfred1: you accelerating?
05:41 PM pfred1: steppers can only accelerate so fast they can't go from 0 to top speed right off
05:41 PM pfred1: not sure why
05:41 PM pfred1: I just know they can't do it
05:43 PM pfred1: I guess they get otu of sync?
05:44 PM pfred1: there is a certain lower speed every stepper motor can start out at though
05:45 PM pfred1: somewhere around 250 RPM or so
05:46 PM JavaBean: not true, 250rpm may not work on every stepper motor
05:46 PM pfred1: I mewan with no load on them
05:46 PM pfred1: litte pancakes they can accel good too
05:47 PM pfred1: I spent a lot of time fooling with stepper motors
05:47 PM pfred1: too much
05:48 PM pfred1: JavaBean but yeah 250 is just an estimate I kind of remember some not starting above 200
05:49 PM pfred1: they just voice coil
06:20 PM _unreal: and he quits
06:21 PM _unreal: ya I dont get it
06:21 PM _unreal: I think its more a factor of the motor controller being a POS
06:21 PM _unreal: I dont understand why its failing on high freq
06:21 PM _unreal: at least it has not burned out any more motor controllers
06:22 PM _unreal: I'v e been watching it. and its weird, the LED turns off and the motor stops. then when the step rate slows down it comes back to life
06:22 PM _unreal: and as to the thing stalling
06:23 PM _unreal: I can be doing a 1000mm movement and it will fail 50% across
06:23 PM _unreal: so that has nothing to do with ramping
06:23 PM _unreal: it has something to do with the design of the motor controller
06:24 PM renesis: maybe its overheating
06:25 PM renesis: did you get gecko drives?
06:30 PM roycroft: that's a silly question
06:31 PM roycroft: if he had gecko drives none of this would be happening :)
06:31 PM JavaBean: shots fired?
06:34 PM roycroft: i just spent an hour and a half dismanting my 3d printer power supply/controller, carefully and with great difficulty assembling the rpi and the controller board in the new enclosure, and reassembling it all
06:35 PM roycroft: the printer controller does not power up now
06:35 PM roycroft: i think the interface cable, which had like 2mm of slack, slipped off when i was reassembling it
06:35 PM roycroft: so i get to do it all over
06:35 PM renesis: you should have put the hot glue there
06:35 PM roycroft: but not today
06:36 PM roycroft: if i did it today i'm afraid expletives might leak out of my mouth
06:36 PM roycroft: the usps reports that on saturday only 43% of ballots in colorado were being delivered to the election centers on-time
06:37 PM roycroft: colorado requires all ballots to arrive on election day, not be postmarked by election day
06:38 PM roycroft: the correct way to win an election is this:
06:38 PM roycroft: 1. run for office
06:38 PM roycroft: 2. convince more people to vote for you than vote for your opponent
06:38 PM roycroft: 3. wait until all the votes are counted
06:38 PM roycroft: 4. have the most votes after they're all counted
06:39 PM roycroft: the incorrect way to win an election is this:
06:39 PM roycroft: 1. run for office
06:39 PM roycroft: 2. prevent people whom you think would not vote for you from voting
06:39 PM roycroft: 3. prevent ballots that you think won't help you from being returned on time
06:39 PM renesis: thats not very american of you roycroft
06:40 PM roycroft: 4. take legal action to stop counting the votes when you're ahead and it appears you might lose your lead
06:40 PM renesis: next you will say that post office is an essential service and not a business
06:40 PM renesis: are you some sort of antiantiantifa?
06:40 PM roycroft: it's the only type of commerce explicitly stipulated in the constitution as something the government should operate
06:41 PM roycroft: i am a man with no label
06:42 PM t4nk_freenode: not on any containers containing what you need in any case :b
06:42 PM roycroft: although i do put labels on most of my stuff
06:43 PM renesis: well maybe if you had a label you would arrive at your destination on time and be counted
06:45 PM jymmmm: roycroft: you label your socks and undies?
06:45 PM renesis: i dont even fold those things
06:45 PM roycroft: i do not
06:45 PM renesis: guys its happening, rent is going down
06:46 PM t4nk_freenode: heh, coincidentally my name is Calvin Klein
06:46 PM renesis: that is both sad and wonderful
07:02 PM pcw_home: _unreal (if you are still here) if the drives minimum step time is 5 usec I would set the step time to 10 usec (10000 ns)
07:04 PM renesis: pcw with the grandma timing
07:33 PM _unreal: ok
07:35 PM _unreal: pcw_home, I'm using the PCCONFIG
07:35 PM _unreal: so so just 10000 across the board under stepper info?
07:35 PM _unreal: XYZ motor config?
07:35 PM _unreal: driver type custom, and 10000 for step on time, step space, direction hold, direction setup?
07:36 PM _unreal: had to pick up my father from the hosptial
07:36 PM _unreal: just got back. he was SUPOSED to be discharged like 6 hours ago
07:55 PM _unreal: just got an odd error
07:55 PM _unreal: Unknown word where unary operation could be "position relative actual" X error
08:01 PM _unreal: figured it out
08:03 PM roycroft: god damn you, alek scarlotos! go to hell and take your robocallers with you!
08:03 PM roycroft: sorry, i just got barraged by calls
08:03 PM Tom_L: now now
08:03 PM roycroft: almost as many as olivia made the other day
08:03 PM * roycroft notes that he voted weeks ago
08:06 PM roycroft: we shall have our first election results in just about 27 hours
08:06 PM roycroft: it's hard to believe this phase of the election is almost oer
08:06 PM roycroft: over
08:06 PM roycroft: harder yet to believe it's lasted as long as it has
08:06 PM roycroft: it seems like it's been going on for decades
08:08 PM XXCoder: yeah
08:09 PM XXCoder: did you read about bunch of people blocking freeway?
08:09 PM XXCoder: insane. its same people who got angry about blm protests on freeway too
08:12 PM roycroft: i read about people in north carolina trying to vote and getting pepper sprayed
08:13 PM roycroft: i think you're talking about the ones who were blockading the biden bus
08:13 PM roycroft: and it was worse than blocking the freeway
08:13 PM roycroft: they were trying to run the bus off the road
08:13 PM roycroft: because they believe in the first amendment
08:13 PM Rab: Haha, that was here.
08:15 PM roycroft: it will be interseting to see what happens to the republican party if they suffer a shellacking come tuesday
08:16 PM roycroft: they've had come to jesus moments many times in the past that they've ignored
08:16 PM roycroft: as have the democrats, if i'm honest, but not to the same degree
08:16 PM roycroft: if dear leader is ousted, will they remain the party of trump?
08:17 PM roycroft: which is a very recent thing for them
08:17 PM roycroft: i suspect a number of them will, and a significant number will make an attempt to return to what republicanism used to be about
08:18 PM roycroft: but i suppose that as long as i can continue ordering and receiving the parts i need, i'm fine with letting them sort that out amongst themselves
08:23 PM XXCoder: roycroft: nah not biden bus one
08:23 PM XXCoder: its day after that
08:24 PM roycroft: i think we should do like switzerland an australia and make voting mandatory
08:24 PM XXCoder: yes please
08:24 PM XXCoder: small fee if no vote
08:25 PM roycroft: it's a lot harder to do voter suppression if it's against the law not to vote
08:25 PM roycroft: well, it's a lot harder to get away with it
08:25 PM roycroft: the excuses don't hold up
08:26 PM * JavaBean points out that not everyone who is a US citizen and in the country is eligable to vote
08:26 PM unterhaus_: the attic ladder I put in isn't long enough
08:26 PM roycroft: correct, javabean
08:26 PM roycroft: and not all should be
08:26 PM unterhaus_: prisoners should be allowed to vote, that is relatively recent
08:26 PM XXCoder: boy was reoublicans pissed when wa started providing easy register at car license centers
08:26 PM XXCoder: that was well before trump era too
08:26 PM JavaBean: unterhaus_, been there, done that. just be glad you weren't in the attic when you discovered that
08:27 PM roycroft: however, convicted felons who have served their sentence should have their voting franchise reenstated
08:27 PM JavaBean: yes, please
08:27 PM roycroft: you know
08:27 PM unterhaus_: I gave up and poked a hole in the ceiling for a ladder
08:27 PM XXCoder: unter yeah except some states coyly made freed prisoners require to pay off debt first
08:27 PM roycroft: like the voters in florida overwhelmingly decided two years ago
08:28 PM roycroft: and the florida legislature reversed
08:28 PM unterhaus_: yeah, they can't even tell them how much it costs to vote
08:28 PM unterhaus_: scotus obviously didn't want them to
08:28 PM roycroft: interesting things come come from the next congress, regarding scotus
08:29 PM roycroft: court packing in the sense of increasing the number of justices is politically infeasible
08:29 PM unterhaus_: no it isnt
08:29 PM roycroft: but there are other things congress could do
08:29 PM roycroft: yes, it really is
08:29 PM unterhaus_: no it's not
08:29 PM unterhaus_: I don't know why people are saying that
08:29 PM unterhaus_: it just takes an act of congress
08:30 PM roycroft: the house already passed legislation putting an 18 year limit on the term of a supreme court justice
08:30 PM roycroft: and they did it in a way that would pass constitutional muster
08:30 PM roycroft: i think that would be a great idea
08:30 PM unterhaus_: 18 years of these guys would ruin the country
08:30 PM roycroft: every president would get, on average, two new justices
08:30 PM roycroft: well, not necessarily
08:31 PM roycroft: the congress could also pass legislation limiting the power of the supreme court
08:31 PM unterhaus_: I think we would end up with a constitutional crisis if they tried that
08:31 PM roycroft: the court does not have any real power vested in it in the constitution
08:32 PM unterhaus_: you'll see, they'll overstep and strike down some perfectly reasonable law and the court will be adjusted
08:32 PM roycroft: the power of the court was given to the court by the court itself, in marbury v. madison
08:32 PM roycroft: and that power has never been challenged by another branch
08:33 PM unterhaus_: they could impeach kavenaugh for not saying who paid off his debts
08:33 PM roycroft: he could be impeached for perjury
08:33 PM roycroft: as could several other justices
08:33 PM unterhaus_: there really doesn't need to be a reason
08:33 PM roycroft: but that's not going to work out
08:33 PM roycroft: and it's not the correct approach
08:33 PM unterhaus_: depends on who paid them
08:34 PM unterhaus_: no, the correct approach is to add justices
08:34 PM roycroft: i disagree
08:34 PM roycroft: for one, that's a slippery slope
08:34 PM roycroft: if the dems pack the court
08:34 PM roycroft: the next time the republicans control the senate and whit house (if they ever do), they'll do the same
08:34 PM unterhaus_: unelected buffoons striking down gay marriage is the thing that will make court packing mandatory
08:35 PM unterhaus_: no, have to control all three
08:35 PM roycroft: and second, nine justices has been a really good number for a long time
08:35 PM * JavaBean looks arround for his popcorn bowl
08:35 PM roycroft: no they don't
08:35 PM roycroft: the house has absolutely nothing to do with supreme courts nominations and confirmations
08:35 PM roycroft: the president nominates, and the senate confirms
08:35 PM roycroft: the house plays no rôle
08:36 PM roycroft: i could see 11 or 13 justices on the supreme court and having it still be functional
08:36 PM unterhaus_: expanding the court takes legislation. Do you need me to explain how that works?
08:37 PM roycroft: but 27, 83, 459?
08:37 PM roycroft: that's not going to work
08:37 PM unterhaus_: sure it is
08:37 PM roycroft: oh, yes, expanding does
08:37 PM jdh: I think you are looking for #ConstitutionalScholars
08:37 PM roycroft: yeah, we're getting pretty off-topic again
08:38 PM roycroft: sorry
08:38 PM roycroft: i'm making indian food for dinner, which i hate doing
08:38 PM roycroft: because it takes a long time, and all those wonderful spices smell up the house while it's cooking, and make me really hungry
08:38 PM roycroft: so i'm trying to find distractions while i'm waiting for it to finish cooking
08:39 PM unterhaus_: hit myself in the hand with a 5 pound hammer
08:39 PM roycroft: don't do that
08:39 PM roycroft: it hurts and causes injury
08:39 PM unterhaus_: now you tell me
08:39 PM unterhaus_: I realized that after
08:39 PM * roycroft is now and always has been a master of the obvious
08:42 PM JavaBean: when all you have is a hammer, all the world looks like your thumb
08:44 PM unterhaus_: index and middle finger, axually
08:44 PM unterhaus_: I was going to put ice on the middle finger, but it's getting better
08:44 PM JavaBean: still ice it
08:45 PM unterhaus_: but it will get cold
08:45 PM JavaBean: i speak from experience
08:49 PM unterhaus_: how do I take a ttl high signal and make it drive an input that is high at 10v?
08:49 PM roycroft: it's finally time to make rice
08:49 PM unterhaus_: thinking about just using a 7404
08:49 PM unterhaus_: and a relay
08:50 PM unterhaus_: or routing my enable signals through to a mesa output on a 7i37
08:50 PM unterhaus_: is there any downside to tying all the enables together?
08:52 PM Tom_L: i did
08:52 PM Tom_L: spindle and drives are separate though
08:58 PM unterhaus_: on separate logic lines?
08:59 PM unterhaus_: all my drives should be enabled at the same time
08:59 PM Tom_L: well, i haven't fully decided
08:59 PM unterhaus_: ic
08:59 PM unterhaus_: did you run it?
09:00 PM Tom_L: i just got the spindle motor today and am figuring the in's and out's of it
09:00 PM unterhaus_: is it a router?
09:00 PM Tom_L: no
09:01 PM Tom_L: BLDC
09:01 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Spindle_motor1.jpg
09:02 PM jdh: wow, quite different from the old one.
09:02 PM unterhaus_: nice. Did that spindle come with the mill?
09:02 PM Tom_L: the spindle is a sherline i moved over to this mill
09:03 PM jdh: what's the cooler
09:03 PM Tom_L: it's coming off
09:03 PM Tom_L: it was to cool the old sherline motor
09:03 PM Tom_L: it got rather hot without it
09:04 PM Tom_L: i just layed the motor off to the side so i could measure the pulley center distance on the new one
09:30 PM roycroft: wow
09:30 PM roycroft: on 60 minutes just now, an interview with the chair of the republican party in arizona
09:31 PM roycroft: party chair: women are being brainwashed by the media
09:31 PM roycroft: interviewer: you're not saying that women can't think for themselves?
09:32 PM roycroft: party chair: "i don't know"
09:32 PM roycroft: the party chair is a woman, btw
09:50 PM renesis: did she start complaining about new star wars and ghostbusters?
09:53 PM roycroft: i suspect she knows of neither
09:53 PM roycroft: and don't forget the mad max reboo
