02:27 AM Deejay: moin
03:15 AM Loetmichel: *giggle* NOW i know why the coffee was great yesterday... just disposed of the 1x4 paper filter that the coworker used yesterday: full to the brim... and then he used 8 cups of water with that. maaan... that stuff was not for the weak hearted ;)
04:14 AM XXCoder: Loetmichel: crazy
05:00 AM Tom_L: morning
05:00 AM jthornton: morning
05:01 AM XXCoder: morning
05:01 AM Tom_L: kindof interesting how ladder logic came about
05:01 AM Tom_L: was snooping around a bit last night
05:02 AM XXCoder: ladder? snooping around?
05:02 AM XXCoder: you a perv?
05:02 AM jthornton: first application was to replace relay logic on auto assembly lines
05:03 AM Tom_L: huh
05:04 AM jthornton: at least that's what I remember seeing once
05:08 AM jthornton: https://en.wikipedia.org/wiki/Programmable_logic_controller#Invention_and_early_development
05:09 AM XXCoder: jt I managed to snag couple mini coke cans
05:09 AM XXCoder: plan to test it with laser
05:09 AM XXCoder: would bne funny if it could engrave it, or even better, cut. doubtful lol
05:10 AM jthornton: mini?
05:10 AM XXCoder: yeah
05:10 AM XXCoder: its smaller than normal soda cans
05:10 AM jthornton: shorter?
05:10 AM XXCoder: and smaller diameter
05:10 AM Tom_L: i think about an elevator cenario all done with relays...
05:12 AM XXCoder: https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcQvtgqg0ILLIZVmweUK8AzssJ0gLWNEdqKZqVXVGrEF5hzbEDdt
05:12 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/Relay1.jpg
05:12 AM Tom_L: like those :)
05:13 AM jthornton: that's some old time relays
05:13 AM Tom_L: i can't remember where i got em now
05:14 AM XXCoder: i dont think im getting my extensions for laser engraver cables anytime soon
05:14 AM XXCoder: hong kong closed down shipping
05:14 AM Tom_L: for holiday or virus?
05:14 AM jthornton: why did they do that?
05:14 AM Tom_L: one or the other...
05:14 AM XXCoder: the fun one. nah lies, its virus
05:15 AM Tom_L: gonna suck for their new year
05:15 AM XXCoder: yeah
05:15 AM jthornton: china locked down the center of the virus trapping 50 million people
05:16 AM XXCoder: if it ever hits india hyper dense area it'll kill so many
05:18 AM XXCoder: isnt it like 100million in just few miles square area?
05:18 AM jthornton: dunno
05:19 AM XXCoder: mumbai, india 76,790 peopl per sqft
05:19 AM XXCoder: erm mi
05:19 AM XXCoder: square mile
05:19 AM XXCoder: 14.4 million in 187 sq miles
05:20 AM XXCoder: less people than I remembered, but more dense than I remembered too
05:20 AM XXCoder: second place is also india, kolkata, india. 62k people per sq mile
05:22 AM p0g0: XXCoder, I'd commend Zelazny's "Stand On Zanzibar", old scifi with a metric like that.
05:22 AM XXCoder: will check in bit
05:27 AM p0g0: Oops, John Brunner, not Zelazny
05:27 AM p0g0: https://en.wikipedia.org/wiki/Stand_on_Zanzibar
05:33 AM p0g0: XXCoder, fwiw, Zelazny is another Hugo winner (6X!) with a magic theme, the Amber series, if you need more scifi.
05:33 AM XXCoder: amer series have em, love em
05:33 AM p0g0: 'k
05:36 AM sensille: so short ... gets expensive on audible
06:40 AM veegee: Hmmm I replaced the motor in my vertical mill (bridgeport clone), now it's very hard to turn the speed to the slowest setting
06:41 AM veegee: I mean it's compressing the discs on the motor side which has a huge spring, but it's a lot harder than the old motor
06:41 AM veegee: I also put some belt dressing on the belt while I was in there. Was that a bad idea?
06:41 AM XXCoder: maybe old one was worn? or theres something in it
06:42 AM veegee: I mean I could turn the dial with the handle before. Now I need to hold it on the wheel with my whole hand to turn it to the very slowest RPM
06:42 AM veegee: going faster is just as easy as before
06:42 AM XXCoder: odd
06:42 AM veegee: Not a big deal, I just hope I didn't do anything wrong
06:42 AM XXCoder: look around because that may be indiction of something that will worsen over time
06:43 AM jthornton: yea something is wrong, it should not be that hard to change speeds when the spindle is running
06:43 AM veegee: this only applies near the very slowest RPM
06:43 AM veegee: anything in the top 3/4 RPM range is same as before
06:44 AM veegee: just like the last 1/8 low RPM range is unusually difficult. Machine runs great otherwise. Power draw is as expected, so motor isn't working harder than it should
06:44 AM XXCoder: is rpm selector rubbing on something?
06:44 AM veegee: I'm guessing the belt dressing I sprayed the belt with made the belt a lot stickier
06:44 AM veegee: no
06:45 AM veegee: it's not the dial that's the issue
06:45 AM XXCoder: ohhh https://www.youtube.com/watch?v=but0X43F4oc
06:45 AM veegee: I suspect that it's just having a hard time compressing the plates on the motor shaft
06:45 AM jthornton: that doesn't sound right
06:46 AM XXCoder: jt check the video its 2.5 min long
06:46 AM veegee: the old motor felt almost as difficult
06:46 AM veegee: but I could still just crank the handle normally
06:47 AM veegee: I mean it's a simple mechanism, so I'm wondering what could be causing that
06:49 AM jthornton: pretty slick, just like the big boys
06:51 AM jthornton: https://www.youtube.com/watch?v=H7KgjMRjuEs
06:51 AM XXCoder: i hate bad introps
06:52 AM XXCoder: damn thats big sbrs
06:52 AM jthornton: yea they are rather stupid
06:55 AM XXCoder: man I want one of those mini stuff lol
06:55 AM XXCoder: dont need it but...
07:00 AM XXCoder: more recent one https://www.youtube.com/watch?v=VN7FUAJP21M
07:00 AM XXCoder: 1.5 min
07:08 AM jthornton: https://www.youtube.com/watch?v=b1U9W4iNDiQ
07:08 AM jthornton: skip the first minute
07:10 AM XXCoder: ya learned about injection process by lego company
07:10 AM XXCoder: pretty cool
07:10 AM jthornton: Monique just laid her first egg this year
09:29 AM jymmmm: Good Morning
09:30 AM jymmmm: jthornton: Is a proud Chicken Daddy, gonna hand out cigars?
10:30 AM gregcnc: anyone follow grimsmo?
10:45 AM Spatial_Suze: hi all
10:46 AM Spatial_Suze: i need ur help, i use grbl for one linear actuator. i you like if is possible to change speed in line gcode. i try X100 F100 and X0 F10; but the speed dont change in the movement, can someone tell me why?
10:46 AM gregcnc: what is actual speed?
10:48 AM Spatial_Suze: $30 maximum spindle speed, rpm = 1000 RPM
10:48 AM Spatial_Suze: $100 x-axis steps per millimeter = 250 steps/mm
10:50 AM Spatial_Suze: $110 X-axis maximun rate mm/min = 500.00 mm/min
10:51 AM Spatial_Suze: i would like justre create a movement A to B and B to A with various speed
10:52 AM gregcnc: i know nothign about grbl, what I'm getting at is the config is probably limiting the speed somehow.
10:52 AM Spatial_Suze: ok
11:02 AM gregcnc: holy crap! mcfarland bought a race track
11:08 AM jthornton: is a grbl a fuzzy little animal?
11:10 AM unterhaus: I forgot I left a linux mint installation going for days now. Hopefully it's okay
11:17 AM Deejay: re
11:24 AM unterhaus: it was finished
11:26 AM unterhaus: I hate it when an order shows "processing" for days on end. Especially when I don't trust the vendor to actually ship
12:21 PM perry_j1987: hows it going guys
12:29 PM JT-Shop: lost the spring clip from the red lead on my Fluke...
12:31 PM Tom_L: that kinds sucks
12:31 PM SpeedEvil: Noooooooooooooo
12:32 PM * SpeedEvil is coming to the conclusion that his wood will not be delivered today
12:32 PM JT-Shop: I'm like WTF where could it go in 30 minutes
12:32 PM gregcnc: I lose stuff in seconds....
12:33 PM * Tom_L glances over at the chickens
12:37 PM * JT-Shop listens to From the Indies to the Andes in his Undies by the Hoosier Hot Shots
12:59 PM unterhaus: turn off the lights and scan at floor level with a flashlight
01:00 PM -!- #linuxcnc mode set to +v by ChanServ
02:26 PM * t4nk_freenode scratches away some dust-mites
02:31 PM miss0r: My "new" car is now sitting in my driveway: https://imgur.com/a/8TuwalU
02:37 PM unterhaus: what are you going to do with that thing?
02:39 PM miss0r: unterhaus: I'm going to convert it into a camper home for the family
02:41 PM beachbumpete1: miss0r: AWESOME!
02:42 PM miss0r: Thanks - They are hard to come by in Denmark these models
02:46 PM unterhaus: I suspect they are relatively difficult to get anywhere
02:47 PM unterhaus: that one looks like it's in good shape, how is the interior
02:47 PM miss0r: "Land rover 101 forward control" google that - they are out there to get
02:47 PM miss0r: pictures lie :) nothing is in particular good shape. Former owner was not big on service. The only thing he realy did for the car was paint the outside in the past 5 years of owning it
02:48 PM miss0r: (and the outside does not include the roof)
02:52 PM unterhaus: I have thought about doing a sprinter conversion
02:53 PM miss0r: Sounds alot easier than doing stuff to a 1977 military vehicle
02:57 PM SpeedEvil: miss0r: 1 gallon per mile?
02:57 PM SpeedEvil: On the plus side, you can DIY parts to a degree
02:57 PM miss0r: 14 mpg, if you please... :)
02:58 PM gregcnc: 14 isn't even bad
02:58 PM gregcnc: gas or diesel?
02:58 PM gregcnc: by US standards
02:58 PM SpeedEvil: Oh - that's smaller than I thought
02:58 PM miss0r: gas driven
02:59 PM miss0r: it even has a LPG system installed.
02:59 PM gregcnc: oh yeah 3.5 V8?
02:59 PM SpeedEvil: - in that the wheel stance (? - distance between) is very much under the trailer
02:59 PM miss0r: yeah
02:59 PM miss0r: 101" is the axle distance
03:00 PM miss0r: ~36" wheels
03:05 PM unterhaus: I seem to have taunted the plumbing gods one too many times. There is a leak under the kitchen sink, but no obvious source
03:06 PM miss0r: lol.. one shall never taunt the gods of sewage...
03:08 PM unterhaus: I violate the 3 trip rule by only taking one trip to the hardware store to complete a plumbing job
03:09 PM unterhaus: Plumbing gods apparently want their other 2 trips
03:10 PM miss0r: you should know better
04:03 PM skunkworks: when we bought this house (old turn of the centruy house moved to a new lot) can you say turn of the century? turn of the century^2?
04:04 PM skunkworks: every plumbing fitting that could be loose was loose...

06:23 PM unterhaus: leak must be due to the dishwasher.
06:35 PM jthornton: fire him if he leaks
06:56 PM _unreal_: finally finally finally.... I got the Y axis put together enough so I can get a measurment on the damn timing belt.
06:56 PM _unreal_: I need a 72" timing belt
07:42 PM nvz: hmm.. I have 12ft of timing belt and two pulleys leftover from my build.. but _unreal_ isn't on right now :P
07:43 PM nvz: https://www.amazon.com/dp/B01KFO1P9K/ is what I bought I only used 3 of the 5 pulleys and have 12ft of belt left over
07:47 PM Tom_L: but he needs continuous belt
07:47 PM CaptHindsight: 72" is wide for belt, how long?
07:48 PM Tom_L: 700'
07:48 PM Tom_L: it's on a conveyor
09:53 PM Connor: okay, so, on our laser cutter. Still having issues. I thought perhaps it was the BOB locking up. It's not. Power cycling the BOB didn't clear the issue. It appears the parport is locking up.
09:54 PM Connor: I've NEVER seen this before in all my dealings with LinuxCNC
09:54 PM Connor: and it's so random..
09:57 PM Connor: Also, anyone have any issues with 5C collets being too tight? I picked up a set, and it's all I can do to get stock in them.
09:57 PM Connor: I have to use a screwdriver to wedge them open enough for the part to slip in..
10:02 PM rue_mohr: static buildup from the movement of the axies cause the metal carriges aren't bonded with conductor wirez?
10:38 PM CaptHindsight: Connor: please define "locking up" on the parallel port
10:39 PM CaptHindsight: try swapping LPT cards or adding one if it's an integrated LPT
10:39 PM CaptHindsight: what are the signals actually doing or not doing?
10:43 PM Connor: After it locks up. The parport doesn't respond anymore. No signals in or out. I was tripping the e-stop, so I disable that input signal in linuxcnc. Next time it happen, LiinuxCNC just kept going like nothing happened, but the steppers stop moving and the laser stop firing and the pin for the e-stop toggled.
10:43 PM Connor: I'm going to try a known good parport card tomorrow and see if that makes any differeance.
10:44 PM Connor: s/I was/it was/g
11:01 PM fjungclaus1 is now known as fjungclaus
