12:27 AM ve7it: jym, missed ya this morning
12:32 AM XXCoder: ve7it: you will have better aim tomorrow
12:32 AM XXCoder: ;)
12:32 AM * jym smacks XXCoder
12:32 AM XXCoder: ow
12:32 AM jym: ve7it: YOu doing HF these days?
12:32 AM ve7it: jym, hope so.... funny you should ask about HF.... just in the process of putting up a new HF antenna
12:32 AM jym: XXCoder: HEre's a damn cookie, now STHU
12:32 AM XXCoder: ow
12:32 AM jym: ve7it: What antenna?
12:32 AM ve7it: jym, all I have up now are 6M, 2M and 440
12:32 AM jym: No 6m (I think)
12:32 AM Wolf__: so just a ht? :P
12:32 AM jym: I have a 2m/440, and a HF rig, but would only be a long wire
12:32 AM ve7it: jym, using the ICOM ah4 tuner ant the feedpoint and then 2 random length pieces of wire across the yard... have to put a small tower up against the house for the center support
12:32 AM Wolf__: sounds odd for 2M
12:32 AM jym: I dont even rememebr what hf rig I have... icom 740??
12:33 AM ve7it: I have too many hf rigs... ic-736, ic-706, ic-751, and an icm700 marine hf
12:34 AM jym: I've never put it on the air
12:34 AM ve7it: the 751 is my oldest radio... from the 80's but still a top notch performer
12:35 AM jym: What antenna are you installing?
12:36 AM ve7it: I lied... also have an IC-781, but its power supply caught on fire... have to take a serious look at it one of these days
12:36 AM * Wolf__ only has a vx7r… which probably needs a new battery pack at this point
12:37 AM ve7it: jym, I guess you could call it an off center fed random length dipole... put as much wire up as I can fit across the yard
12:37 AM jym: lol
12:38 AM jym: Both my HT's need batteries, I want to get/find an empty case and use lipo
12:38 AM jym: liion
12:40 AM Wolf__: yeah, kinda my thought as well, get a AA conversion pack and use 14500 cells in it
12:40 AM ve7it: yea... I guy gave me a couple of ic-f3s 2M handhelds without battery packs..... I am wondering if I can 3d print a pack with maybe 3 18650s, a boost regulator and a charging circuit all in the case
12:41 AM Wolf__: vx7r is a extra pain in the ass for the battery pack design
12:42 AM jym: Wolf__: Can't find it... Kenwood HT-D7a
12:42 AM ve7it: with my main handheld, I just use AA batteries as I only tend to use it a few times a year for events... costco rules
12:44 AM ve7it: I live out in the sticks, so a mobile with 25+ watts and a decent antenna are required to get anywhere there are other hams!
12:44 AM Wolf__: jym: https://www.amazon.com/ExpertPower-FNB-58-FNB-58Li-FNB-80-FNB-80Li/dp/B00EDWPLD2 that for the radio I have https://www.amazon.com/Battery-Yaesu-Radio-VX-5R-VX-6R/dp/B078C69KF6
12:45 AM jym: Wolf__: screw your ht, I need a battery back for mine =)
12:46 AM Wolf__: TH-D7a?
12:47 AM jym: yeah
12:48 AM jym: https://www.universal-radio.com/catalog/ht/4211.html
12:49 AM Wolf__: http://store.batteriesamerica.com/bt-11h6xaabatterycaseforkenwoodth-d7ath-g71ath-d7eetc.aspx might be a way to hack li-ion in to it
12:50 AM jym: $25, bastards
12:54 AM ve7it: https://www.amazon.ca/gp/product/B07MX6CFQZ I ordered a couple of these
12:56 AM Wolf__: blah for us w/ our fancy HT with odd packs lol
01:01 AM jym: yeah, no shit
01:27 AM Loetmichel: _unreal_: Anet A8
01:36 AM Jymmm: Loetmichel: I don't have a problem with it either, _unreal_ does though =)
01:40 AM Loetmichel: i just saw a really tiny brad nailer in a "maker" video... WANT! :-)
01:40 AM Loetmichel: (and a framing gun... but the money....)
01:41 AM Loetmichel: but i meant: that thing would be suitable for a kid
01:46 AM sensille: trust your kids
01:47 AM Loetmichel: sensille: and removing brad nails from fingers is a good learning experience how NOT to do it. will happen only once ;)
01:47 AM Loetmichel: i gurantee you that ;)
01:48 AM XXCoder: lol my bro was working for someone when he shot a brad nail off into somewhere in yard
01:48 AM XXCoder: he told my bro to find it.
01:48 AM XXCoder: it took my bro quite a while but he did find it
01:51 AM Loetmichel: https://youtu.be/FwzoHHrnpFA?t=47 <- there.. isnt that thing cuuuuuuute?
01:52 AM Loetmichel: XXCoder: supermagnets FTW ;)
01:56 AM XXCoder: looking
01:56 AM XXCoder: lol he was not permitted to get magnets
01:56 AM XXCoder: hard lession on not shooting it off
02:04 AM Loetmichel: i do that shooting off nails too. but i usually aim at the trashcan
02:04 AM Loetmichel: not into the yard
02:05 AM Loetmichel: its easier to just shot off a couple nails until it works again than to search why the nailer jammed "yet again!"
02:05 AM XXCoder: yeah though that wasnt case for my bro
02:07 AM Loetmichel: i DO have the habit of shooting off electronic pars legs into the void here at the company when i am done soldering them in... those PCB snips shoot the legs quite fare thru the workshop ;)
02:07 AM XXCoder: lol
02:07 AM Loetmichel: sometimes you can even hear them ricochet off the flourescent tubes on the ceiling ,)
02:07 AM sensille: make sure to aim for other eletronics
02:08 AM Loetmichel: sensille: the $500k R&S spectrum analyzers for example :-)
02:09 AM Loetmichel: ... they even make the same sounds as bullet riccochets sometimes
02:09 AM sensille: 500k? right, that's your core business. i hope it has some ventilation slots where the legs can enter
02:09 AM Loetmichel: :)
02:09 AM Loetmichel: it has
02:10 AM sensille: great
02:10 AM Loetmichel: but inside all is enclosed a second time into cast aluminium shilding boxes ;)
02:10 AM Loetmichel: we had one SAs PSU explode on us
02:11 AM Loetmichel: sounded like a hand grenade gone off
02:11 AM Loetmichel: it broke half a dozen M4 screws that held the cast alu box closed
02:12 AM sensille: that looks spacy: https://www.amazon.de/dp/B07MZRWPQG/
02:12 AM Loetmichel: thats when i opened it, looked inside: "nope, not even trying to fix that. Send it to R&S!"
02:13 AM Loetmichel: why dio i get a hentai tentacle vibe from that?
02:13 AM sensille: that thing actually looks helpful
02:13 AM * Loetmichel pulls his mind out of the gutter :-)
02:14 AM Loetmichel: i use a simple desk vise with a ball joint at the bottom for that
02:14 AM Loetmichel: https://www.youtube.com/watch?v=_xnwZU2bd2Q <- like that
02:15 AM sensille: i was searching for a magnifying glass on an arm
02:15 AM sensille: and got that tentacle monster
02:17 AM Loetmichel: i like the magnifying glasses on my nose better
02:17 AM Loetmichel: those on the arm are never in the right position and always in the way
02:17 AM sensille: yeah, i already admired them in the video
03:43 AM * Loetmichel just 3d-printed a new nozzle for the air gun. Old one disappeared somehow. Never thought to find the exact part i needed on thingiverse... 30min, 4gr PLA at ~8 cent and i got a working air gun again... isnt 3dprinting great? ;)
03:43 AM XXCoder: tomorrow you will find missing one
03:44 AM Loetmichel: XXCoder: possible
03:44 AM Loetmichel: or should i say "very probably so"?
03:44 AM Loetmichel: :-)
03:45 AM XXCoder: :)
05:10 AM jthornton: morning
05:12 AM Tom_L: morning
05:13 AM XXCoder: morning
05:15 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Mill_Holder10.jpg
05:15 AM Tom_L: finally got a decent part but there's still a little runout
05:16 AM jthornton: that threads on your spindle?
05:16 AM Tom_L: yes
05:17 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Mill_Holder11.jpg
05:30 AM Tom_L: fwiw, i went .007" over on the threads to get a 'good' fit
05:33 AM Tom_L: +.002" on the .500 hole. that cutter must be a little undersize
05:36 AM XXCoder: looks nicely milled
06:18 AM methods_: https://www.reddit.com/r/holdmyfeedingtube/comments/ca8q81/hmft_after_i_kick_a_wild_bear
06:18 AM methods_: the manliest of all sports
06:19 AM methods_: after poking hungry sharks with short sticks
06:21 AM XXCoder: that person is a dumbass
06:23 AM methods_: among other titles you win from that
06:24 AM XXCoder: https://www.smbc-comics.com/comic/2009-04-16
06:26 AM methods_: i guess that guy read that comic
06:26 AM XXCoder: maybe
06:27 AM XXCoder: trying to graduate to smbc level
06:29 AM jthornton: https://forum.linuxcnc.org/41-guis/36838-plot-widget-for-qtpyvcp#138760
08:20 AM Tom_L: nice jthornton, yours?
08:24 AM Tom_L: methods_, we see it because the bear didn't eat the camera
08:38 AM jthornton: Tom_L: no, someone else made that
08:47 AM methods_: or maybe someone found the camera in a pile of bear poop
09:00 AM perry_j1987: morning
09:04 AM JT-Shop: morning
09:04 AM perry_j1987: lost a drillbit
09:05 AM JT-Shop: I'm constantly losing stuff
09:05 AM perry_j1987: after doing numerous holes just fine it started a new hole and look and the brass was cherry red
09:05 AM perry_j1987: in the first few mm of depth
09:05 AM perry_j1987: odd
09:13 AM SpeedEvil: In general, when cutting brass, that is probably bad.
09:13 AM SpeedEvil: Also, wasn't the sound 'slighty' different?
09:14 AM SpeedEvil: I'm quite surprised you can get brass to do that, I wouldn't have thought it would easily get to cherry red, even if flow drilling.
09:25 AM perry_j1987: i was suprised to
09:26 AM perry_j1987: lets see.
09:26 AM perry_j1987: 9730 rpm 140mm/min plunge
09:26 AM perry_j1987: 1/16 drillbit
09:29 AM perry_j1987: and hmmm just rebooted the linuxcnc computer and now it seems the pcie serial /parallel card isnt working
09:29 AM perry_j1987: ugh more to fix
09:31 AM SpeedEvil: Do you mean the brass was cherry red, or the drill?
09:31 AM perry_j1987: the brass was
09:32 AM * SpeedEvil wonders if there is a new chinese steel/nanoparticulate iron oxide yellow metal.
09:33 AM perry_j1987: heh
10:58 AM perry_j1987: what speeds and feeds do you guys come up with for 1/16 drillbits?
10:58 AM jthornton: depends on the material and the limits of your spindle
10:59 AM perry_j1987: its one of those 2.2kw watercooled 24000 rpm spindles
10:59 AM perry_j1987: so no real torque below 6k rpm or so
10:59 AM perry_j1987: in brass
11:01 AM jthornton: http://www.vikingdrill.com/viking-Drill-FeedandSpeed.php
11:01 AM jthornton: might be a good place to start
11:11 AM JT-Shop: perry_j1987: 150 SFM on a 0.0625 Drill is 9167RPM and 300SFM is 18,335 RPM
11:12 AM perry_j1987: i just found another problem
11:12 AM perry_j1987: when i converted this machine to linuxcnc the only spindle test i did was hitting the butto nin axis hearing it turn on
11:12 AM perry_j1987: then stepping it up and down seemed to work
11:12 AM perry_j1987: when i cranked the button all the way on it sounded about the right speed
11:13 AM perry_j1987: well i just looked down at the vfd and it was only 382k instead of 400 at max
11:13 AM perry_j1987: so there's issue there
11:13 AM perry_j1987: then that lead me to a further test
11:13 AM perry_j1987: mdi S9000 m3
11:13 AM perry_j1987: and it shot up to 382k on the vfd
11:13 AM perry_j1987: so that was odd
11:14 AM perry_j1987: so thats around 22k rpm
11:14 AM perry_j1987: real speed
11:14 AM JT-Shop: bbl
11:16 AM perry_j1987: k
11:20 AM perry_j1987: got some reading to do on spindle control again to get this fixed
11:55 AM perry_j1987: hmm
11:56 AM perry_j1987: just went through all the settings set the scale to 24000
11:56 AM jym: Morning folks
11:56 AM perry_j1987: but when i comand it to move 24000 the vfd only goes to 382.4 instead of 400
11:57 AM perry_j1987: could it be this 5axis breakout board card not outputting the full 10v or something?
11:57 AM perry_j1987: it takes a pwm input and converts it to 0-10v for me
12:07 PM perry_j1987: just put multimeter on it and 10.38v output when commanded to go 24k rpm
12:07 PM perry_j1987: hmm
12:09 PM gloops: blame china
12:12 PM gloops: maybe an offset
12:14 PM perry_j1987: when i was running mach3 i had this chinese controller card that was running the show
12:14 PM perry_j1987: it was doing 400 back then
12:17 PM perry_j1987: so i see this vfd can do serial/modbus
12:17 PM perry_j1987: does that give me spindle speed output too for linuxcnc?
12:28 PM gloops: not used it myself, someone will tell you
12:35 PM gloops: https://www.forum.linuxcnc.org/38-general-linuxcnc-questions/33720-spindle-synchronisation-is-it-working-the-way-it-should
12:36 PM perry_j1987: ugh just broke another dirllbit
12:37 PM perry_j1987: these calculators are terrible
12:37 PM perry_j1987: its funny you only find them on tool manfuacturer websites heh
12:37 PM perry_j1987: conspiracy to make us buy more tools
12:38 PM gloops: yeah makes sense theyd err on the side of high tool failure
12:39 PM gloops: plenty of variables not tool related that can be blamed
12:41 PM perry_j1987: drilling should be somewhat basic of an op right?
12:48 PM roycroft: feed and speed recommendations are just that - recommendations
12:48 PM roycroft: you have to adapt them to your particular environment
12:48 PM roycroft: and the manufacturer-published ones tend to err on the side of aggressiveness, as in most production environments labor costs more than tooling
12:49 PM roycroft: i.e. it's cheaper to replace the tooling more often than to take longer to do the job
12:50 PM roycroft: the first question i would ask is: how much runout does your spindle have? :)
12:50 PM Loetmichel: roycroft: also the manufactuer likes to sell new tools ;)
12:50 PM roycroft: loetmichel: overrating the tooling is not a good way to do that though
12:51 PM roycroft: if your failure rate is too high your customers will go elsewhere
12:51 PM Loetmichel: i know
12:51 PM Loetmichel: but they go as close as they can get away with to that barrier
12:51 PM roycroft: the real takeaway from this is:
12:51 PM roycroft: feeds and speeds are not laws - they are recommendations to get you started
12:51 PM Loetmichel: also "bigger numbers look nice in the datasheet" ;)
12:52 PM perry_j1987: so who is publishing sane recommendations then
12:52 PM perry_j1987: lol
12:52 PM roycroft: most manufacturers
12:52 PM Loetmichel: if not all
12:52 PM perry_j1987: i have not seen a single shred of evidence to back that claim roycroft :P
12:53 PM Loetmichel: point is that the manufacturers feeds/speeds are usually "absolute max"
12:53 PM roycroft: it's more likely your machine or your gcode that's the problem
12:53 PM Loetmichel: and you do good to stay BELOW that
12:53 PM roycroft: yes, what loetmichel said
12:53 PM roycroft: take the recommended settings, and slow down by 30% or so
12:54 PM roycroft: if that works well, slowly increase until you suffer premature tooling failure
12:54 PM roycroft: then back off a bit again
12:54 PM perry_j1987: slow which down
12:54 PM perry_j1987: lots of sliders to pick from heh
12:54 PM Loetmichel: easiest would be the feedrate
12:54 PM perry_j1987: at this poitn i dont mind if it took 3 minutes to drill one hole :P
12:54 PM perry_j1987: i dont have money to throw at this project to keep buying tools lol
12:54 PM roycroft: there is no single answer to your question
12:55 PM Loetmichel: perry_j1987: hmmm... not like this? https://www.youtube.com/watch?v=m7eO5cu-fXg
12:55 PM Loetmichel: ok, i cheated: that are 5mm heaxagons. not drills
12:55 PM perry_j1987: if i filmed all my tool breaks so far i'd have enough to do a cut scene montage
12:55 PM roycroft: perry_j1987: part of learning to machine involves experimentation and replacing tooling
12:55 PM perry_j1987: lol
12:56 PM Loetmichel: in 1,5mm thick alu ;)
12:57 PM Loetmichel: perry_j1987: i have a box with about 1.5kg of broken 1/8" tungsten carbide tool shafts on that machine
12:57 PM Loetmichel: and its already the second fill
12:57 PM Loetmichel: sent one off to the scrapyard already
12:57 PM Loetmichel: ( you get money for that, tungsten carbide is expensive!)
12:58 PM perry_j1987: i just cant find anybody talking about conservative numbers that will let you get through a single hole drilled :P
12:58 PM Loetmichel: meaning: expect a lot of tools to break until you get a "feeling" for the machine and make no errors any more. (if ever)
12:59 PM roycroft: i just told you to slow down by 30%
12:59 PM roycroft: i have no idea what you're doing
12:59 PM Loetmichel: yeah, what roycroft says
12:59 PM roycroft: if you're drilling a hole, are you pecking or going full bore all at once?
12:59 PM roycroft: if you're not pecking, you should be
12:59 PM Loetmichel: take the tool manufacturers advice, reduce feedrate 30%, try
12:59 PM Loetmichel: should work
12:59 PM roycroft: use the correct rpm for the material
01:00 PM roycroft: slow down the feed rate on the peck
01:00 PM roycroft: there is no magic formula to make everything work perfectly
01:01 PM roycroft: you have to actually understand what you're doing to succeed at it
01:01 PM perry_j1987: aye
01:01 PM roycroft: observe the operation and determine why your tooling is breaking
01:01 PM roycroft: then fix that problem
01:01 PM Loetmichel: ... or you could do it like this: https://www.youtube.com/watch?v=mj8sGEf8Wf8 *ram bam thank you ma'm*
01:01 PM Loetmichel: :-)
01:01 PM Loetmichel: (thats 2mm carbon plate, a few 100 3mm holes ;)
01:02 PM perry_j1987: i seem to have a disconnect to how i run a drill press when i can feel the work and this cnc heh
01:02 PM Loetmichel: "the optimum feedrate is found when the drill "screws into the plate" like a screw ;)
01:02 PM perry_j1987: i just looked and somehow the peck drilling got turned off from when i first setup this cam
01:02 PM Loetmichel: and you get corkscrew like swarf from carbon plate ;)
01:03 PM Loetmichel: perry_j1987: whats your machine?
01:03 PM roycroft: there you go
01:03 PM perry_j1987: 6040
01:03 PM roycroft: turn it back on
01:03 PM Loetmichel: and what hole you want to drill?
01:03 PM roycroft: and stop breaking drills :)
01:03 PM Loetmichel: in what material
01:03 PM Loetmichel: how deep?
01:04 PM perry_j1987: brass 1/16
01:04 PM roycroft: 1/16" is pretty small
01:04 PM perry_j1987: 1/16 bit
01:04 PM roycroft: and brass is pretty gummy
01:04 PM perry_j1987: its a very squeeky metal
01:04 PM perry_j1987: reminds me of cheese curds
01:04 PM roycroft: it's no wonder you're breaking drills if you're not peck drilling
01:04 PM Loetmichel: any chance to get the drills to ONE end of the gantry?
01:04 PM roycroft: you're not clearing your chips
01:04 PM perry_j1987: i have my vise all the way to the left
01:05 PM perry_j1987: chips were consistently flying out at me
01:05 PM Loetmichel: roycroft: 1,5mm deep with an 1,5mm drill bit warrants no peck drilling
01:05 PM perry_j1987: during the entire holes that did complete successfully
01:05 PM perry_j1987: doing about inch deep
01:05 PM perry_j1987: well less
01:05 PM roycroft: 25mm does :)
01:05 PM perry_j1987: 5/8 to 3/4 deep
01:05 PM roycroft: 15mm does
01:05 PM roycroft: 18mm does
01:05 PM Loetmichel: ah, so not 1/16" brass=
01:06 PM Loetmichel: i thought
01:06 PM roycroft: 1/16" diameter drill
01:06 PM Loetmichel: i see
01:06 PM roycroft: which is pretty small
01:06 PM roycroft: i assume that your part is not in motion when you're drilling
01:07 PM Loetmichel: perry_j1987: i asked about getting close to the gantry sides because the 6040 has unsupported rails on the gantry
01:07 PM Loetmichel: if the spindle is in the middle it bends pretty easily
01:08 PM Loetmichel: the drilling force can be enough
01:08 PM Loetmichel: for it to tilt up or down
01:08 PM roycroft: also, if you have not modified your drill it will get really grabby with brass
01:08 PM roycroft: positive rake is not good for drilling brass
01:08 PM Loetmichel: perry_j1987: is you drill bit HSS or carbide?
01:10 PM * roycroft would recommend hss while the tooling is still breaking frequently
01:12 PM gloops: yeah optimum feed/speed recs is just that - assuming ideal conditions, not factoring in for any slack or chatter in the machine, or the work piece moving
01:15 PM roycroft: perry_j1987: if you're using unmodified drills for the brass, get a little diamon hone and file a tiny flat on the cutting edges
01:15 PM perry_j1987: it is a crappy harbor freight drillbit
01:15 PM roycroft: oh, well that's the main reason you're breaking them
01:15 PM roycroft: hf drills are made of pot metal, not hss :)
01:15 PM perry_j1987: but they have black oxide coating which makes them impervious :P
01:15 PM gloops: they dont snap for nothing though
01:15 PM perry_j1987: na i got their 1120 piece set for 7 bucks super deal
01:16 PM perry_j1987: bought it for the nice steel holder and plan on replacing them with better ones as needed / they break
01:16 PM roycroft: i'm serious about grinding zero rake flats on the cutting edges
01:16 PM roycroft: copper is even worse than brass for being grabby
01:16 PM perry_j1987: do you have a picture of what you mean
01:16 PM roycroft: but brass does a pretty good job of it
01:16 PM roycroft: i do not
01:16 PM gloops: oil it
01:17 PM roycroft: teh gogle probably does
01:17 PM roycroft: positive rake = recipe for failure with copper/brass
01:17 PM gloops: oil can/car oil
01:17 PM roycroft: http://www.chaski.org/homemachinist/viewtopic.php?t=90388
01:17 PM roycroft: there you go
01:18 PM roycroft: there's a picture in that article
01:18 PM roycroft: about 1/2 way down
01:18 PM roycroft: my google fu is working today
01:18 PM roycroft: usually it does not
01:20 PM roycroft: ha
01:20 PM roycroft: that article even mentions using a diamond hone
01:21 PM perry_j1987: sending someone out to ACE to get some of their drillbits
01:21 PM perry_j1987: ah so the leading edge file it flat in-line with the drillbit so its not coming to a V?
01:22 PM roycroft: you file a flat so the cutting edge is at a 90 degree angle to the part
01:23 PM roycroft: which will help keep it from grabbing the part
01:23 PM perry_j1987: ok
01:26 PM roycroft: turn peck drilling back on too
01:27 PM perry_j1987: aye i'll have the new bits soon i'll file a flat on the edges like that pic and im generating the new gcode now with peck turned back on
01:27 PM perry_j1987: ty
01:27 PM perry_j1987: Loetmichel i was looking at the x axis on this thing
01:28 PM roycroft: since you'll have several new drills i would recommend changing one thing at a time testing, and noting the behavior change
01:28 PM perry_j1987: it doesnt look like it'd be too much work to mill a channel out the back of the alum bracket that holes the linear bearings
01:28 PM perry_j1987: so you could fit supported rail bearings in
01:28 PM roycroft: btw, i am still a 100% manual machinist
01:28 PM perry_j1987: then all one would have to do is mount a C channel to the back of the uprights and mount some supported rails off that
01:28 PM roycroft: but cnc machining is just manual machining that is automated
01:28 PM Loetmichel: perry_j1987: only helps if you have something to mount the SBRs to ;)
01:29 PM roycroft: you still have to do the same things
01:29 PM Loetmichel: dont do a C channel
01:29 PM Loetmichel: do a box channel
01:29 PM perry_j1987: ya that'd keep it from twisting
01:29 PM perry_j1987: when i got the bit stuck in the brass
01:30 PM perry_j1987: i could easily see where all the flexing was going on
01:30 PM perry_j1987: it did not appear to be any percevable in the z axis but the two smooth rods for x were twisted from eachother
01:30 PM Loetmichel: yeah, i know
01:30 PM Loetmichel: drilling the vacuum table wasnt pretty
01:30 PM Loetmichel: and its only made of phenolic paper
01:30 PM perry_j1987: heh
01:31 PM Loetmichel: https://www.youtube.com/watch?v=ZwAizto843U
01:31 PM perry_j1987: this upgrade would be able to reuse alot of the existing parts which is nice
01:31 PM Loetmichel: thats a 0.8mm tungsten carbide bit
01:31 PM Loetmichel: the 3.175mm drill bit before that though...
01:31 PM Loetmichel: petty bad flexing
01:32 PM Loetmichel: (same program, so pretty fast feeds)
01:33 PM Loetmichel: ... there are jobs that take the whole day ;)
01:35 PM roycroft: what did your chips look like, perry_j1987?
01:35 PM roycroft: were they long, stringy chips?
01:35 PM roycroft: or nice little c-shaped or g-shaped chips?
02:51 PM Deejay: gn8
02:52 PM miss0r: Don't you just love it when you make a spline and it just fits with close to no slack
02:52 PM miss0r: :D
02:52 PM miss0r: Now for the real work piece - this one was just a test
02:56 PM JT-Shop: the test piece you made the other day?
02:58 PM miss0r: yeah.. now I made it on a shaft replica
02:58 PM miss0r: to test the setup
03:00 PM miss0r: https://imgur.com/undefined
03:00 PM miss0r: well.. not that :D
03:00 PM miss0r: https://imgur.com/a/STT9WPH
03:02 PM JT-Shop: are you cutting that profile or grinding it?
03:05 PM miss0r: cutting
03:06 PM miss0r: I reground a a 60degree disc cutter to do the flat bottom
03:13 PM JT-Shop: cool
03:14 PM JT-Shop: 32°C here at the moment
05:13 PM Connor: anyone have a pack of 10 inserts setting around? I need general dimension of the packaging.
05:15 PM Tom_L: it would depend on the insert type
05:15 PM Connor: My inserts where DCMT 070204
05:15 PM Connor: But, I thought most of those where pretty much the same size..
05:16 PM JT-Shop: plenty of different sizes
05:16 PM Tom_L: if i were guessing i'd say about 2 x 5 or 6"
05:16 PM Connor: Ordering some Schaller Bins for endmills and insert packs.
05:19 PM Tom_L: https://www.cleartecpackaging.com/boxes-insert.html
05:19 PM Tom_L: take your pick
06:14 PM * jthornton spent the last 3 hours trying to get the hood latch cable out of the truck, finally got the third nut loose that holds the parking brake pedal...
06:26 PM Elmo40: did you first remove the fuel tank? these things are all interconnected...
06:27 PM Elmo40: maybe shake the tail light, too.
06:31 PM jthornton: well I removed the bed of the truck...
06:33 PM _unreal_: hello
06:33 PM _unreal_: just got home
06:36 PM _unreal_: I assume its everywhere but MAN beer got cheap
06:37 PM jthornton: MAN beer?
06:37 PM _unreal_: just picked up a 24 pack of miller high life I HATE miller highlife but 24can for $10 at walmart
06:38 PM _unreal_: jthornton, yes MAN beer. I don't do that woman BEER
06:39 PM _unreal_: its MAN beer
06:40 PM TurBoss: http://github.com/jethornton/mill_touch_v6/
06:41 PM jthornton: a 12 pack of cerveza lasts me 12 days...
06:41 PM _unreal_: !?
06:41 PM TurBoss: I'm JT too
06:41 PM _unreal_: me 3-6 days
06:41 PM roycroft: so what you call "man beer" is what everyone else calls shite :)
06:41 PM jthornton: too many carbs so I switch to wine after my cerveza
06:41 PM TurBoss: :P
06:42 PM TurBoss: :)
06:42 PM _unreal_: TurBoss, What is that github?
06:42 PM * jthornton used to brew 25 gallon batches of beer but weighed 240 lbs too
06:42 PM * roycroft brews smaller batches, but still has s problem getting rid of it all, because he doesn't drink much any more
06:43 PM _unreal_: I love doing home made beer. HELL I have 6 different meads done now
06:43 PM roycroft: i typically brew 40L batches
06:43 PM TurBoss: _unreal_: is a interface for linuxcnc that jthornton wrote
06:43 PM jthornton: I experimented with making 1 gallon all grain batches for a while
06:43 PM _unreal_: I have tamerind mead, mango, pumpkin, raspberry mead anda few other types
06:43 PM _unreal_: SOOOO god
06:43 PM roycroft: too much work for too little reward
06:43 PM jthornton: yup
06:43 PM roycroft: which is why i doubled my batch size
06:43 PM jthornton: but it was fun to experiment
06:44 PM roycroft: twice the beer for barely any more effort
06:44 PM _unreal_: barely any effort? surely you jest
06:44 PM roycroft: no, i do not
06:44 PM _unreal_: :)
06:44 PM roycroft: it takes a couple more minutes to mill the grain
06:44 PM jthornton: yep, no effort at all making beer
06:45 PM roycroft: maybe an extra half hour for the brew session
06:45 PM jthornton: takes a couple more seconds for me to mill...
06:45 PM roycroft: so 6-1/2 hours instead of 6 hours
06:45 PM * TurBoss uploaded an image: image.png (91KB) < https://matrix.org/_matrix/media/v1/download/jauriarts.org/VrGKniFkAZZmNYzfyaJugImS >
06:45 PM roycroft: that's worth it for an extra 20L of beer
06:45 PM _unreal_: :)
06:45 PM jthornton: http://gnipsel.com/beer/equipment/Mill.htm
06:45 PM _unreal_: roycroft, what type of bottles do you bottle with?
06:45 PM _unreal_: I use the..... ahhh
06:46 PM _unreal_: what the hell are they called
06:46 PM roycroft: i very rarely bottle
06:46 PM _unreal_: those greeen bottles with the ceramic top
06:46 PM roycroft: that's far too much work
06:46 PM roycroft: 97.5% of my beer gets kegged
06:46 PM _unreal_: ahh KEGGING :)
06:46 PM _unreal_: even better
06:46 PM roycroft: but when i do bottle i use style-appropriate bottles
06:46 PM jthornton: I used to use cola canisters called cornies or something like that
06:46 PM _unreal_: grolsh
06:46 PM _unreal_: I use grolsh how ever you spell it bottles
06:46 PM roycroft: yes, corney kegs
06:47 PM roycroft: grolsch
06:47 PM jthornton: http://gnipsel.com/beer/equipment/beer-equipment.html
06:47 PM roycroft: anyway, i need to go break down a sheet of plywood
06:47 PM roycroft: and not talk about brewing right now
06:47 PM _unreal_: I have 50+ grolsch bottles on hand.
06:47 PM jthornton: still working on the store?
06:47 PM jthornton: or stand?
06:47 PM _unreal_: roycroft, karate chop?
06:48 PM roycroft: yes, drawers for the grinder stand
06:48 PM roycroft: one more sheet of 12mm ply to break down and cut up
06:48 PM jthornton: grinding herbs?
06:48 PM roycroft: and i still have to get a sheet of 18mm for the drawer fronts, but that will have to wait until after the fair
06:48 PM roycroft: belt grinder
06:49 PM roycroft: for grinding steel
06:49 PM jthornton: ah
06:49 PM jthornton: the one you made?
06:51 PM _unreal_: roycroft, I think the best beer for its type I ever made was this tamarind beer few years ago. using tamarind paste, and I believe a germin beer base I'd have to find my book to tell exactly what it was made from
06:51 PM _unreal_: but OH my god it was so good.
06:51 PM _unreal_: I called it numb tongue
06:52 PM _unreal_: because tamarinds if you eat to any will make your mouth numb. I'm not kidding, if you dont know what they are. they kind of look like a super sized peanut with a brown flesh inside and big seeds and they are VERY sour...
06:52 PM _unreal_: depending on the type
06:53 PM _unreal_: but OMG that beer was sooo good
06:54 PM _unreal_: I believe at its core it was a wheat beer
06:54 PM _unreal_: if memory serves
06:56 PM _unreal_: gloop come back.... come back..........
06:56 PM _unreal_: SIGH
06:59 PM _unreal_: SO.. I'm going to go take a quick shower grab and other beer and code my next cut for a bit. I'm thinking about designing a micro touch probe for the hell of it
06:59 PM _unreal_: easy to build design
07:21 PM _unreal_: shhhhhh
07:41 PM perry_j1987: evening guys
07:54 PM perry_j1987: im going insane i think
07:57 PM _unreal_: I knew it
07:57 PM perry_j1987: heh
07:58 PM perry_j1987: i just postprocessed some gcode ran it on the rotary axis
07:58 PM perry_j1987: then tried post processing some more. and it wont run
07:58 PM perry_j1987: lol
08:10 PM perry_j1987: ok think its coming back to me now heh
08:10 PM perry_j1987: i havnt tried my 4th axis since moving to linuxcnc
08:11 PM perry_j1987: so the postprocessor i had setup for 4th axis was back on mach3 heh
08:17 PM _unreal_: way back in the way back ehhhh
08:20 PM perry_j1987: heh
08:26 PM perry_j1987: so apparently linuxcnc was able to run some gcode from mach3 postprocessor
08:26 PM perry_j1987: but not all of it
08:55 PM flyback is now known as phlyback
08:55 PM phlyback is now known as flyback
09:23 PM andypugh: perry_j1987: That’s a surprise, I thought that Mach3 G-code was largely identical to LinuxCNC.
09:25 PM andypugh: Connor: 95.25mm x 39.52mm x 10.66 mm. If you want any more spurius accuracy I would need to get the mircrometers out.
09:28 PM andypugh: Those are some that were sat next to the PC that I bought in a job-lot, had no use for, and have not yet offloaded. (TGCR08 x 20, TPMR16 x 1)
09:36 PM perry_j1987: 4th axis is alot of fun
09:51 PM Tom_L: hand coding 4th axis is even more fun
09:53 PM Tom_L: perry_j1987 what codes failed?
10:36 PM perry_j1987: i fixed it
10:36 PM perry_j1987: i had forgotten i havnt used 4th axis since i converted to linuxcnc
10:36 PM perry_j1987: and i outputted gcode from my old mach3 post processor on one of the computers hhe
10:36 PM perry_j1987: so had to make a postprocessor for linuxcnc setup for my 4th axis
10:36 PM perry_j1987: now im off and running
10:56 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20190708_161814.jpg
10:58 PM Connor: That a tormac tool holder and a knockoff? :)
10:58 PM Tom_L: you made the left one?
10:58 PM skunkworks: yes
10:59 PM Tom_L: funny i tried to make a sherline holder last night but it's got more runout than i'd hoped for
10:59 PM skunkworks: That was the whole point of this adventure...
11:00 PM skunkworks: The final bore was done in the green machine.
11:00 PM Tom_L: checking runout?
11:00 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Mill_Holder10.jpg
11:00 PM Tom_L: that was my best attempt so far
11:00 PM Tom_L: all mill
11:00 PM skunkworks: yes - the tormach one was .0015 out at the tip.. further further out.
11:01 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20190708_225437.jpg
11:01 PM skunkworks: cool!
11:01 PM Tom_L: looks good
11:01 PM Connor: yup. looks good.
11:01 PM skunkworks: rough around the edges but it has it where it counts :)
11:02 PM Tom_L: i checked one that i purchased and it had runout but not quite as much as mine
11:02 PM Tom_L: i need a 'real' spindle :)
11:02 PM Connor: You do it in a lathe? or on the mill?
11:02 PM Tom_L: who?
11:02 PM Connor: skunkworks:
11:03 PM skunkworks: I cheated.. Mostly done on the mazak lathe...
11:03 PM Tom_L: some of it looks like lathe
11:03 PM skunkworks: I have video if I can get it up
11:03 PM Connor: Do the shank to 3/4" then mount in a lathe and bore it out.
11:03 PM Connor: err. in the mill.
11:03 PM Tom_L: what's the slot in the original for?
11:03 PM Tom_L: tool changer grip?
11:04 PM Connor: Tool changer fingers
11:05 PM skunkworks: yes - And this is for a probe which will never go into the tool changer
11:06 PM skunkworks: Most all was done in one operation on the mazak.. - then the monarch - then the actual mill for final boring
11:07 PM Tom_L: why?
11:07 PM Tom_L: why not just lathe the whole part?
11:07 PM skunkworks: The back pocket, taper and back drilling was done on the monarch
11:07 PM Tom_L: my lathe is shot or i would have
11:08 PM Tom_L: runout on it is way worse
11:08 PM skunkworks: Monarch is a lathe..
11:08 PM Tom_L: right
11:09 PM Tom_L: did you turn the part in the mill spindle to bore it?
11:09 PM skunkworks: yes
11:09 PM Tom_L: i thought about trying that
11:09 PM skunkworks: so it should be as good as I can get it... :)
11:10 PM skunkworks: time will tell
11:10 PM Connor: Yup.
11:10 PM Tom_L: how did you hold the cutter?
11:10 PM skunkworks: vise
11:10 PM skunkworks: vice that has a little v cut in it for holding round stock..
11:10 PM Tom_L: yeah
11:10 PM skunkworks: https://youtu.be/YZI7Q7O_PcY
11:11 PM skunkworks: not up yet.. still uploading
11:11 PM Tom_L: i'll check tomorrow
11:11 PM Tom_L: bedtime here
11:11 PM Tom_L: i might try one more that way but i'm gettin kinda burned out on it
11:12 PM Tom_L: did you drill a hole first then a boring tool?
11:12 PM skunkworks: yes
11:13 PM Tom_L: i guess i could drill the hole on the lathe then go to the mill
11:13 PM skunkworks: I drilled and bored it on the mazak to within .003ish..
11:13 PM skunkworks: then finish bored it on the mill
11:14 PM Tom_L: mmm
11:14 PM Tom_L: i may have to try one that way
11:14 PM Tom_L: the sherline mill holders break .125 cutters at the grub screw. i'm hoping to use a valenite extension to hold them in the mill holder instead
11:15 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/valenite/valenite_holder1.jpg
11:15 PM Tom_L: something like that
11:15 PM Tom_L: i had to re'purpose that holder for something else
11:16 PM Tom_L: the .125 carbide cutters are just too small and the grub screw cracks them after a while
11:17 PM skunkworks: Cool
11:17 PM Tom_L: i'm not happy about how far it will stick out but i'll try it
11:17 PM Tom_L: was a 6" collet extension
11:18 PM skunkworks: heh - going to be about an hour to upload
11:18 PM Tom_L: i'll not wait up :)
11:18 PM skunkworks: Can you make it any shorter?
11:18 PM Tom_L: no
11:19 PM Tom_L: it's as short as it can get
11:19 PM skunkworks: I bet if you can make it coaxial it will work way better
11:20 PM Tom_L: hope so
11:48 PM ItsFlipp: what are the main differences between vibratory and tumbling setups for deburring?
