08:37 AM -!- #linuxcnc mode set to +v by ChanServ
10:31 AM Unterhaus_: woodpeckers must have a grinder, but it appears they didn't use it on their new square
10:38 AM LUNADA_DESKTOP: odd post to walk in on lol
10:41 AM LUNADA_DESKTOP: apparently this machine has brakes on 3 out of 4 servos
10:41 AM LUNADA_DESKTOP: the x axis is the only one that doesnt
11:00 AM JT-Cave: LUNADA_DESKTOP, would it help you if mesact could get a list of all the pins on your boards?
11:04 AM JT-Cave: geez I had to remove the rear fender and the receiver to cut the lock off the Bluewing so I could take the trailer hitch out
11:05 AM JT-Cave: does woodpeckers make their stuff? or do they farm it out?
11:08 AM roycroft: they manufacture their own tools
11:08 AM roycroft: they own blue spruce toolworks now as well
11:08 AM JT-Cave: didn't know that or I forgot
11:09 AM roycroft: bridge city were bought by harvey tools a few years ago
11:09 AM roycroft: harvey tools manufacture their own stuff, but they have a plant in china where the make most of it
11:09 AM roycroft: woodpeckers make their stuff in ohio, though
11:11 AM JT-Cave: my new yuasa battery has failed in just a few months... I'm getting tired of buying them for the bluewing
11:51 AM LUNADA_DESKTOP: agm or wet cell?
11:51 AM JT-Shop_: agm IIRC
11:51 AM LUNADA_DESKTOP: got it on a tender or ride it often at least?
11:51 AM JT-Shop_ is now known as JT-Shop
11:51 AM JT-Shop: I put it on a tender about once a month
11:52 AM JT-Shop: I've had batteries in the past that never needed anything but they were wet cell
11:52 AM -!- #linuxcnc mode set to +v by ChanServ
11:53 AM LUNADA_DESKTOP: weird. no power draws anywhere?
11:53 AM JT-Shop: should not be any power draws with the key off, it's a 09 goldwing
11:54 AM LUNADA_DESKTOP: i've had really good luck with lithium batteries in my bikes
11:54 AM LUNADA_DESKTOP: i've left them completely dead for at least a year and no issues
11:56 AM LUNADA_DESKTOP: so i got 2 moving axes on the machine now
11:56 AM JT-Shop: nice
11:57 AM * JT-Shop hears a nap calling his name
11:57 AM LUNADA_DESKTOP: i'm having issues with the y axis (dual motor, gantry)
11:57 AM JT-Shop: issues?
11:57 AM LUNADA_DESKTOP: i think i have something configured wrong as it shows 4 joints instead of xyz in axis
11:57 AM JT-Shop: did you home the gantry?
11:58 AM LUNADA_DESKTOP: i did not because i havent been able to move it under power at all
11:58 AM LUNADA_DESKTOP: inthe y axis
11:58 AM JT-Shop: did you set the home sequence to a negative number for the gantery?
11:58 AM JT-Shop: gantry
11:59 AM LUNADA_DESKTOP: i did but then it would only let me move the x axis by jogging without homing
11:59 AM LUNADA_DESKTOP: so i changed that
11:59 AM Tom_L: jt, odd.. seems you just bought that battery
11:59 AM JT-Shop: yes I did
11:59 AM LUNADA_DESKTOP: i'm just trying to make sure things are moving in the correct directions and whatnot
11:59 AM JT-Shop: https://www.youtube.com/watch?v=1OtWNuLWfwc
12:00 PM JT-Shop: gantry homing example
12:00 PM JT-Shop: a gantry must have the home sequence set to a negative number for one or more joints and they all must have the same number
12:01 PM LUNADA_DESKTOP: so there's no way of jogging it without homing it first?
12:01 PM JT-Shop: you can configure it to not move when homing
12:01 PM LUNADA_DESKTOP: ah
12:01 PM LUNADA_DESKTOP: yea i forgot about that
12:01 PM JT-Shop: you can only jog joints until homed
12:02 PM LUNADA_DESKTOP: it wont let me jog at all except for x with -2 in the y axis home sequence
12:02 PM LUNADA_DESKTOP: not even z, which i thought was weird
12:02 PM JT-Shop: when you power up does the DRO show all 0's
12:03 PM LUNADA_DESKTOP: yea
12:03 PM JT-Shop: ah you must start the home sequence with either 0 or 1 and not skip a number
12:03 PM LUNADA_DESKTOP: having 4 joints instead of 3 axes in the dro isnt wrong?
12:03 PM LUNADA_DESKTOP: (3 axis gantry)
12:04 PM JT-Shop: that is correct until you home the joints for the gantry
12:04 PM LUNADA_DESKTOP: got it, ok
12:04 PM JT-Shop: run the axis gantry sim
12:04 PM LUNADA_DESKTOP: i'll try homing without moving and go from there, thanks
12:04 PM JT-Shop: np
12:04 PM JT-Shop: now it's really nap time
12:05 PM LUNADA_DESKTOP: i pretty much made the config by hand so i figured i screwed up something
12:05 PM Tom_L: can o soup and nap in my immediate plans
12:05 PM LUNADA_DESKTOP: i just got to work about an hour ago lol. no naps for me
12:06 PM Tom_L: it's noon o'clock here
12:06 PM LUNADA_DESKTOP: 10am here
12:06 PM Tom_L: banker's hours..
12:06 PM LUNADA_DESKTOP: already almost 70 out
12:06 PM LUNADA_DESKTOP: i changed my hours for traffic reasons
12:07 PM LUNADA_DESKTOP: they're doing construction on the highway and it's been screwing up my commute
12:07 PM LUNADA_DESKTOP: i'll start at 8 once they're done
12:08 PM LUNADA_DESKTOP: anyway, back to the grind. thanks for the help.
01:16 PM solarwind: I like to annoy machinists by pronouncing fillet like "fish fillet"
01:23 PM solarwind: regrinding a broken carbide insert for a sharp edge works surprisingly well. Lack of coating doesn't seem to be an issue
01:23 PM solarwind: Definitely not a $10/insert issue
01:46 PM solarwind: Hmm, why aren't CBN inserts used for regular mild steel?
01:46 PM solarwind: Is there any disadvantage? Are they more prone to chipping/breaking?
02:00 PM roycroft: you should go down to florida an hang out with abom for a week, solarwind
02:00 PM roycroft: he can teach you all about inserts
02:41 PM LUNADA_DESKTOP: well it's all jogging and moving now
02:41 PM LUNADA_DESKTOP: just gotta get the spindle working and then i can focus on tuning
02:42 PM LUNADA_DESKTOP: had to add a timedelay for the z axis brake so it didnt drop and cause a following error when i powered it up
03:01 PM JT-Shop: sounds like your making progress LUNADA_DESKTOP
03:02 PM LUNADA_DESKTOP: yep. since i've picked up some plc programming skills since my last retrofit, it's coming to me more naturally now
03:03 PM LUNADA_DESKTOP: you were right though, it was the homing thing.
03:06 PM LUNADA_DESKTOP: pretty sure the spindle thing is mainly due to the change to multi spindle support since i used the hal sections from my other machine and it didnt like that. should be easy enough to fix
03:16 PM JT-Shop: yup spindle.0.something for pins
03:20 PM Tom_L: motion.spindle was changed to ^^
03:22 PM Tom_L: after 2.7x
03:27 PM JT-Shop: trying another maintainer/charger on the bluewing battery
03:56 PM roycroft: i have a half dozen of these: https://www.amazon.com/dp/B00068XCQU
03:56 PM roycroft: they work brilliantly, and i've had them for years
03:57 PM Tom_L: 64°F
04:32 PM LUNADA_DESKTOP: got the spindle working
04:33 PM LUNADA_DESKTOP: getting an unexpected realtime delay on task 0
04:36 PM LUNADA_DESKTOP: cant see any latency spikes when running a test. most i see is about 100,000. seems to only do it when loading linuxcnc.
04:45 PM JT-Shop: I might be ready to drop the forks by the time I quit
04:48 PM LUNADA_DESKTOP: nice
04:48 PM LUNADA_DESKTOP: got a spring compressor?
04:48 PM JT-Shop: no
04:48 PM LUNADA_DESKTOP: or do you not need one on that bike
04:48 PM JT-Shop: not needed on the gl1800
04:51 PM JT-Shop: the hardest part was unplugging the display panel
04:53 PM LUNADA_DESKTOP: that was the worst part on my tl1000r. the springs were stiff
04:53 PM LUNADA_DESKTOP: i had to make a spring compressor
04:53 PM JT-Shop: how do you get the cap on with a spring compressor?
04:55 PM LUNADA_DESKTOP: it's been over 20 years so i forgot, but iirc, it may have compressed the cap down with the spring so you could start the threads?
04:55 PM JT-Shop: that makes sense
04:56 PM LUNADA_DESKTOP: they sell specific compressors for them
04:56 PM LUNADA_DESKTOP: i was just young and poor
04:56 PM JT-Shop: I remember then
04:56 PM LUNADA_DESKTOP: now i'm old and poor
04:57 PM LUNADA_DESKTOP: ok time to start tuning. wish me luck
04:57 PM JT-Shop: should be easy, have you seen my guide?
04:59 PM JT-Shop: roycroft, https://youtu.be/qC11ouRH13w?t=961
04:59 PM JT-Shop: have you used a guide like that?
05:00 PM TurBoss: Hello!
05:00 PM JT-Shop: yo TurBoss
05:01 PM TurBoss: Mr. JT :)
05:01 PM XXCoder: yo the boss
05:01 PM TurBoss: i'm about to enable a relay bot
05:01 PM TurBoss: to the matrix and discord
05:02 PM JT-Shop: what will it do?
05:02 PM TurBoss: it will "relay" msgs from irc to that networks
05:02 PM JT-Shop: cool
05:02 PM XXCoder: relay text :) though there wont be mass nick joins as that requires server stuff thats still disabled
05:03 PM XXCoder: cant wait to see it woprk tur :)
05:03 PM TurBoss: :)
05:03 PM TurBoss: it joining
05:03 PM TurBoss: *its
05:04 PM TurBoss: \o/
05:04 PM lcnc-relay: <Relay> <~Turboss> \o/
05:04 PM TurBoss: :(
05:04 PM lcnc-relay: <Relay> <~Turboss> :(
05:04 PM XXCoder: sounds like some issue come up
05:04 PM TurBoss: :)
05:11 PM lcnc-relay: <TurBoss> hello!
05:12 PM TurBoss: pong?
05:12 PM lcnc-relay: <Relay> <~Turboss> pong?
05:12 PM lcnc-relay: <JT (@jt-shop:matrix.org)> Ping
05:13 PM lcnc-relay: <roguish> TurBoss: you are a genius. !!!!!!!!!!!!!!!!!!
05:13 PM TurBoss: still bit buggy
05:13 PM lcnc-relay: <Relay> <~Turboss> still bit buggy
05:13 PM TurBoss: :D
05:13 PM lcnc-relay: <Relay> <~Turboss> :D
05:13 PM lcnc-relay: <xxcoder> yep. thats why turboss handles bridging stuff lol. I only manage rss bot
05:14 PM TurBoss: lul
05:15 PM TurBoss: the last test nº 1
05:15 PM lcnc-relay: <Relay> <~Turboss> the last test nº 1
05:16 PM TurBoss: the last test nº 2...
05:16 PM lcnc-relay: <Relay> <~Turboss> the last test nº 2...
05:16 PM XXCoder: sounds like bot is eaching back all irc comments?
05:17 PM lcnc-relay: <Relay> <~XXCoder> sounds like bot is eaching back all irc comments?
05:17 PM JT-Shop: https://youtu.be/qC11ouRH13w?t=1499
05:17 PM lcnc-relay: <Relay> <~john> https://youtu.be/qC11ouRH13w?t=1499
05:18 PM TurBoss: yes it fails to compare its own name :/
05:18 PM lcnc-relay: <Relay> <~Turboss> yes it fails to compare its own name :/
05:20 PM TurBoss: it should be ok?
05:20 PM TurBoss: it is
05:20 PM TurBoss: :D
05:20 PM XXCoder: awesome
05:21 PM lcnc-relay: <roguish> TurBoss: more better
05:21 PM Roguish: ok, that was typed in on Element
05:30 PM Tom_L: TurBoss, can they see this side?
05:31 PM lcnc-relay: <turboss> yes
05:31 PM Tom_L: just not a gob of nicks
05:31 PM lcnc-relay: <JT (@jt-shop:matrix.org)> Yes
05:32 PM Tom_L: so if you direct a message to someone you can't do that from irc
05:32 PM XXCoder: yeah thats the downside to this type of bridge
05:32 PM XXCoder: cant do tab autocmplete also
05:32 PM Tom_L: depending on the traffic that could be either good or bad
05:35 PM JT-Shop: yup
05:38 PM Tom_L: get the back tire changed?
05:38 PM JT-Shop: decided to rebuild the forks while it's on the center stand
06:14 PM LUNADA_DESKTOP: ugh, fun. i'm getting racking while homing the y axis
06:14 PM LUNADA_DESKTOP: only on the index search
06:15 PM LUNADA_DESKTOP: or at least it's getting a following error
06:19 PM LUNADA_DESKTOP: i suspect that the gantry is too stiff to allow any misalignment and the indexes are too far apart on each encoder to actually reach both at the same time.
06:19 PM LUNADA_DESKTOP: which makes sense
06:21 PM LUNADA_DESKTOP: doing some reading, i assume it's covered somewhere
06:21 PM LUNADA_DESKTOP: but the rest of the machine is homed via home switches and index. getting closer
06:49 PM rene-dev5 is now known as rene-dev
07:58 PM LUNADA_DESKTOP: so i figured out it just moves to the first index and parks during the homing sequence. then eventually gets a following error on the second joint of the gantry.
07:58 PM LUNADA_DESKTOP: it doesnt seem to be trying to move when it gets that following error
10:25 PM solarwind: https://www.youtube.com/watch?v=cXbd3XQKMMQ Surface Speed and Finish
10:26 PM solarwind: This has been my exact experience as well, but I don't understand why
10:26 PM solarwind: When the carbide insert starts throwing sparks, that's when you get the really good surface finish. But it also burns up the insert
10:27 PM solarwind: The difference is remarkable. It's the difference between the crappy mild steel surface finish everyone is familiar with vs. almost a mirror like finish with nothing but the surface speed being increased
10:28 PM solarwind: around 240m/min is where you start getting really good surface finish
