12:27 AM elbartek: ok anyone here??
12:30 AM elbartek: need some advice again
12:30 AM elbartek: found a good spindle rated 380v 3ph... I only got 110/220v 1ph at home... Is there any VFD that actually does that or its chinese propaganda crap?
12:30 AM elbartek: I am so f***** skeptical of throwing my hard earned money on a huanyang brand vfd lol... I guess even the rs485 voltage spec if off by 20%
12:33 AM elbartek: I know I can do 220v 1ph to 220v 3ph with a good Delta VFD... ... but never seen 220v 1ph to 380v 3ph... althought he Huanyang Co. Inc. Tm. Super number one company claims it does... at 5.5kw
12:34 AM elbartek: Is there anyway to get 3ph 380v in North America from the grid? lol
12:35 AM elbartek: I have a hospital not too far
12:36 AM elbartek: so wait... the huonyang VFD actually has a step up transfo integrated ...
12:37 AM elbartek: ahh... maybe they have a different sqrt(2) when handling RMS
12:39 AM elbartek: 220v*sqrt(2) = 311.126983722v ... minus the losses
12:42 AM elbartek: in china... sqrt(2) = 380/220 ----> sqrt(2.98347107438)*220 = 380... hence... 2 American Units = 2.98347107438 China Units
12:43 AM elbartek: okay given that.... we can always use 2/3 factors for reviewing any chinese specs (I'm being nice)
12:44 AM elbartek: when they say 300W... its actually 200W.... but yeah... 200W struggling watts going thru piss poor caps that will leak in a few months
12:53 AM elbartek: hey how about buying a chinese VFD... dumping all the electro caps and soldering some new Rubicons / Nippons in?
12:53 AM elbartek: or maybe I'll just buy it and try to flush it down the toilet and put the video on youtube
01:01 AM fragalot: hi
01:05 AM elbartek: hi
01:40 AM xunil: elbartek, i would watch your "will it flush" video
01:45 AM IchGucksLive: hi from Germany
01:46 AM IchGucksLive: coooooold
01:46 AM fragalot: very
01:46 AM IchGucksLive: elbartek: still on ?
01:56 AM IchGucksLive: im off till later
03:05 AM Deejay: moin
04:34 AM jthornton: morning
04:48 AM XXCoder: hey jthornton
04:48 AM jthornton: hey XXCoder
04:48 AM XXCoder: whats up
04:49 AM jthornton: finally v carved that harley logo sunday
04:49 AM XXCoder: good eh
04:49 AM jthornton: came out real nice
04:49 AM XXCoder: yiou got vcarver?
04:50 AM jthornton: I used the BP knee mill and f-engrave
04:50 AM XXCoder: ahh cool. is f0engrave good?
04:51 AM jthornton: seems to be once you get the hang of it
04:51 AM XXCoder: looks free?
04:52 AM jthornton: yea it is free and it's based on a program that is based on a program that I wrote lol
04:52 AM XXCoder: lol ok
04:52 AM jthornton: I thought it was cool to see my name in the credits
04:53 AM XXCoder: I want to engrave something then cast some low temp metal on it
04:53 AM XXCoder: like pewler
04:57 AM jthornton: https://makezine.com/2015/07/20/introduction-lost-wax-casting/
05:00 AM XXCoder: https://www.youtube.com/watch?v=pqTDxf7x8ew
05:15 AM jthornton: that looks easy
05:16 AM XXCoder: yeah
05:16 AM XXCoder: pewler temp melt is so low it dont really affect wood
05:16 AM XXCoder: yet high enough it wont deform or melt in really hot day
05:17 AM XXCoder: basically perfect for casting fun
05:40 AM Tom_L: 39°F
05:44 AM Tom_L: JT-Shop, your page looks better now
05:44 AM Tom_L: musta paid the bill? :)
05:45 AM Tom_L: pics eat alot of space
05:45 AM jthornton: they increased the memory limit in the php.ini file
05:45 AM jthornton: nothing to do with pics
05:46 AM Tom_L: huh
05:54 AM jthornton: it failed to open a cache.language file that is 167b
05:57 AM jthornton: something on their end broke, both stores were fine yesterday morning and both broke yesterday afternoon
08:12 AM Loetmichel: HA! Finally got the Fiberoptic 2* 4 in 1 switch working... have to redesign the prototype PCB quite a bit though... (maaan, what a mess!) -> http://www.cyrom.org/palbum/main.php?g2_itemId=17031&g2_imageViewsIndex=1
08:38 AM JT-Shop: Tom_L: the error was trying to do a flock() fwrite() and fflush() on a file
08:59 AM skunkworks: That looks like something I built!
09:02 AM Loetmichel: skunkworks: its a prototype. with a few errors of mine and an attached IR remote reciver as an afterthought ;)
12:22 PM Tom_L: jthornton, which one did it fail on?
12:37 PM JT-Shop: Tom_L: https://pastebin.com/tqj0en72
12:55 PM IchGucksLive: hi
01:03 PM fragalot: hi
01:09 PM IchGucksLive: holzjunkie: any chip
01:09 PM IchGucksLive: beside chio
01:10 PM holzjunkie: no nothing sorry
01:10 PM IchGucksLive: hi jimm
01:12 PM IchGucksLive: jimmylu2333-fedo: ni hao to goungzuo
01:17 PM IchGucksLive: ok im off for today
01:32 PM gloops: all quiet on the Western front
02:06 PM Tom_itx: http://paste.debian.net/1015741/
02:06 PM Tom_itx: any ideas?
02:11 PM jdh: homed?
02:18 PM Tom_L: of course
02:19 PM Tom_L: i might have figured it out
02:32 PM JT-Shop: Tom_itx: why are you homing again?
02:32 PM Tom_L: i'm not
02:32 PM Tom_L: just on power up
02:32 PM Tom_L: but the stored coordinates for G54 G55 fail after power up
02:33 PM Tom_L: it goes to G54 ok but not G55
02:33 PM Tom_L: i get that error
02:33 PM Tom_L: i set it up last night but didn't have time to run the part
02:33 PM JT-Shop: your text says your homing twice
02:34 PM Tom_L: the NGCGUI button sends it to the x0 y0 z0 fixture offset for the active offset
02:34 PM JT-Shop: ah
02:34 PM Tom_L: that's _that_ home
02:35 PM Tom_L: i home to machine home on power up
02:35 PM JT-Shop: home is the machine home not a fixture offset
02:35 PM Tom_L: yeah i probably didn't word that the clearest
02:36 PM JT-Shop: yea saying home for coordinate system offset is confusing
02:36 PM Tom_L: it works fine until i power cycle the machine
02:36 PM cradek: Tom_L: did you see my response and do what I suggested in the other channel?
02:36 PM Tom_L: not sure what gets changed there
02:36 PM Tom_L: yeah, i don't use G92
02:36 PM Tom_L: but i'll check the screen
02:37 PM Tom_L: may have to do it later though
02:39 PM Tom_L: i can see i need to edit the sub a bit if i'm gonna start using multiple fixtures
02:39 PM Tom_L: change G0 Z0 to G28 Z0 then put G0 Z0 after the x y Move
02:40 PM Tom_L: especially if G54 Z is lower than G55 Z
02:40 PM cradek: when do you use this button?
02:41 PM Tom_L: i use fixture offsets for all my programs. generally it's just been G54 which is default
02:41 PM cradek: usually my work origins mean the tool is touching the top of the work. it would be a mistake to rapid to it. so you must be doing something else.
02:41 PM Tom_L: after setting them up, i generally send the machine there to start
02:41 PM Tom_L: i set Z 1" or more above the work
02:41 PM Tom_L: and fix it in the cad model
02:41 PM Tom_L: it's a safety thing i just got used to doing
02:43 PM Tom_L: then like you say, if you rapid to it, you're safe
02:43 PM Tom_L: i know lots of guys here touch off the work, but i've never done it that way
02:44 PM Tom_L: on 4 axis or multiple fixtures we often used a tooling ball as home
02:46 PM Tom_L: then you can have P1 on one side of the toumbstone and P2 on the opposite
02:47 PM gregcnc: There is no reason for that. That move should be part of the program and the machine should be somewhere way up high in Z when you start.
02:48 PM Tom_L: you live in days where cad can do it all :)
02:49 PM gregcnc: what do you mean?
02:50 PM Tom_L: back then it was alot of work doing multiple fixtures in one program
02:50 PM gregcnc: I mean your move to XYZ0,0,0 boefore startingthe program
02:50 PM Tom_L: now you can put them all in the model and hide the inactive ones
02:50 PM Tom_L: it's just a habit
02:51 PM gregcnc: no point
02:51 PM Tom_L: the point being if it goes where you told it, the program won't jam the first tool into the work
02:51 PM gregcnc: if the offset is wrong it will still crash
02:51 PM gregcnc: it may
02:51 PM Tom_L: not necesarily
02:52 PM Tom_L: it could yes
02:52 PM Tom_L: but it gives you an 'ohshit' moment to react
02:53 PM gregcnc: that should be during dry run
02:53 PM Tom_L: i agree
02:53 PM Tom_L: like i said, not everybody does it this way
02:53 PM gregcnc: did you get your button working?
02:54 PM Tom_L: which button?
02:54 PM gregcnc: mdi g5x xyx0
02:54 PM Tom_L: this issue isn't resolved yet no. i ran out of time for now
02:55 PM Tom_L: gotta leave here in a few min
02:55 PM gregcnc: ah
02:56 PM Tom_L: not sure how that sub became a symbolic link though
02:56 PM Tom_L: i'll have to find it and fix that
02:59 PM XXCoder: I always walk it in
02:59 PM XXCoder: expecially when unproven program
03:05 PM JT-Shop: Tom_L: I set some offsets for G54 and G55 and shut down axis and start back up and they are there
03:08 PM Tom_L: did you move to their zero offsets?
03:08 PM Tom_L: the values are there on mine but i get that error
03:08 PM Tom_L: i'll fiddle with it later. gotta go here pretty quick
03:11 PM JT-Shop: yea
03:12 PM Tom_L: not sure why i'd get a positive limit error when the numbers are negative
03:13 PM Tom_L: anyway, bbl.
03:21 PM XXCoder: I guess they are getting truckload of thoughts and prayers ready again
03:21 PM XXCoder: school shooting.
03:22 PM andypugh: I 3D printed some actual structural ans useful parts at the weekend. For pretty-much the first time.
03:22 PM andypugh: http://bodgesoc.blogspot.co.uk/2018/03/LED.html
03:23 PM Deejay__ is now known as Deejay
03:24 PM Deejay: re
03:24 PM XXCoder: andypugh: thats printed? did you do some finishing work?
03:45 PM JT-Shop: nice
03:57 PM andypugh: Only the adaptor rings are printed. The finned disc things are original Yamaha parts.
04:00 PM XXCoder: ahh
04:00 PM JT-Shop: we went for a 200 mile ride Saturday... froze our ass off on the way back
04:00 PM XXCoder: car ride or?
04:01 PM JT-Shop: BlueWing
04:01 PM XXCoder: bluewing boots?
04:02 PM JT-Shop: temp dropped 8F after lunch and all I had on was my bluejean shirt, wife had a T shirt on
04:02 PM JT-Shop: seat wasn't plugged in so the grip heater would not work either
04:03 PM JT-Shop: Blue GoldWing
04:03 PM andypugh: You wouldn’t have wanted to ride around in a T-shirt round here last saturday, it was snowing, and cold with it.
04:04 PM XXCoder: ah motorcycle
04:06 PM JT-Shop: yea got down to 13C for a while
04:06 PM XXCoder: kansas measles. People aren't vaccining for some reason
04:06 PM CaptHindsight: andypugh: maybe a near-a-snowmobile project this summer? :)
04:07 PM XXCoder: jt so seat had warmers but wasnt plugged in?
04:07 PM CaptHindsight: do they sell snow mobiles in the UK?
04:07 PM andypugh: I doubt that they sell many.
04:07 PM JT-Shop: when I put the seat on I didn't push till it clicked so it fell out
04:08 PM andypugh: Almost nowhere has snow for more than a couple of days at a time, and then it’s rarely more than a few inches.
04:08 PM XXCoder: doh
04:08 PM CaptHindsight: 12C here Sunday, now back to 2C all week
04:09 PM CaptHindsight: andypugh: how about the hills of Scotland, same story?
04:09 PM gloops: turned out nice this afternoon, not that warm but leasant and sunny, birds singing in the hedges etc
04:09 PM gloops: pleasant
04:10 PM andypugh: There are some ski resorts in Scotland, so they will have a few there, I reckon.
04:10 PM CaptHindsight: was hoping to get out to Islay before tourist season
04:11 PM andypugh: There’s not a lot there. :-)
04:11 PM andypugh: But more than there is on Jura
04:11 PM JT-Shop: I had to use channel lock pliers to get the plug and socket to lock... springy seal
04:13 PM andypugh: Having said that, we spent a nice holiday on Islay when I was a kid, for two weeks. (including driving there and back)
04:14 PM CaptHindsight: my favorite aged ethanols come from there
04:15 PM JT-Shop: hmm the sun is out, time to noodle head around with the chickens and have a beer
04:15 PM andypugh: I was imagining that was the attraction.
04:15 PM CaptHindsight: any news from archivist?
04:16 PM CaptHindsight: he's been pretty quiet lately
04:16 PM andypugh: I like them all, too. But I think my favourite is actually from a lot further north: https://en.wikipedia.org/wiki/Highland_Park_distillery
04:17 PM CaptHindsight: big fan of https://en.wikipedia.org/wiki/Ardbeg_distillery
04:18 PM CaptHindsight: if peat came in the bottle I might be only slightly happier
04:20 PM andypugh: Some of the drinking water on the islands looks like whisky there is so much peat in it.
04:20 PM CaptHindsight is now known as PeatFromIslay
04:21 PM PeatFromIslay: have to take a side trip to Ireland as well
04:22 PM PeatFromIslay is now known as CaptHindsight
04:24 PM andypugh: One of the reviews here: https://www.proof66.com/whiskey/ardbeg-corryvreckan-single-malt-scotch.html says “Perfection if you're partial to drinking out of a cigar's ash tray. And I am"
04:28 PM andypugh: This is the most hacky musicl instrument I have ever seen: https://www.youtube.com/watch?v=MUdWeBYe3GY
04:29 PM CaptHindsight: andypugh: yes, strong smoke
04:31 PM CaptHindsight: andypugh: where did you go for winter testing this year?
04:31 PM andypugh: Finland and the Alps
04:32 PM CaptHindsight: must be difficult to predict
04:33 PM CaptHindsight: looks like the Chinese have jumped onto the laser etching and SLS parts bandwagon
04:33 PM gregcnc: 100USD SLS for everyone?
04:33 PM CaptHindsight: getting there
04:34 PM CaptHindsight: galvo heads $300, RF lasers $3k, diode lasers $1k
04:36 PM CaptHindsight: gregcnc: LCD based SLA printers for $500
04:37 PM gregcnc: are they just ignoring patents?
04:37 PM gregcnc: or have they started expiring?
04:37 PM andypugh: The Chinese ignoring patents? Perish the thought!
04:38 PM CaptHindsight: SLS patents started expiring
04:39 PM CaptHindsight: LCD panels just started being produced with very small pixels for cheap
04:39 PM gregcnc: oh that's great, that seems a good method
04:41 PM CaptHindsight: https://maxdesign1990.files.wordpress.com/2016/05/diagram-1.png?w=980&h=842&crop=1
04:57 PM gloops: https://www.mirror.co.uk/news/uk-news/uk-weather-britain-bake-3-8017294 hottest summer for 100 years coming
04:59 PM SpeedEvil: Lies.
05:00 PM gloops: well they post these sensational weather forecasts every year, bound to be right sometimes
05:06 PM Deejay: gn8
05:39 PM elbartek: hello anyone there??
05:40 PM JT-Shop: sometimes
05:40 PM elbartek: how can I run a 3kw 380v 3ph spindle at home^^ got ideas?
05:40 PM elbartek: VFD?
05:41 PM elbartek: run it on 220? VFD single phase to tri-phase
05:41 PM JT-Shop: what is your normal voltage?
05:41 PM elbartek: 220 single phase hah
05:41 PM elbartek: im in Canada
05:41 PM elbartek: dont want to spend too much on conversion..
05:42 PM elbartek: just that I have this high end colombo spindle...
05:42 PM JT-Shop: a rotary phase converter is easy to build but then you need a transformer
05:42 PM JT-Shop: can you wire the motor for 240v?
05:42 PM elbartek: I really dont know...
05:42 PM elbartek: giordano colombo rv 90.2
05:43 PM elbartek: doest specify connection on name plate
05:43 PM elbartek: doesnt
05:43 PM elbartek: well... constructing a phase converter and a transformer will cost me more then the motor no?
05:43 PM elbartek: I picked up the motor for 500$
05:44 PM gloops: says you can run them on 230v
05:44 PM elbartek: where?
05:44 PM elbartek: I didnt find a spec sheet
05:44 PM JT-Shop: the transformer yea, I get used motors here for a $50 to make a RPC
05:44 PM gloops: 7.5 HP, RV 90/2 FP1 SB CPE 25 DX, Electric Spindle, 220/380 V, 21.6/12.5 A, 18000/24000 RPM, 300/400 Hz, 2 Pole
05:44 PM JT-Shop: if it runs on 230v then a RPC or a VFD
05:44 PM elbartek: yeah but the 1phase to 3phase conversion can be handled by VFD
05:45 PM gloops: well 5hp and 7.5hp do
05:45 PM JT-Shop: yea 3HP is the usual limit for single phase to three phase
05:45 PM elbartek: its a 7hp
05:45 PM elbartek: just states 380v tri phase on nameplate
05:45 PM gloops: http://www.maxymtechnologies.com/Maxym%20Support/Spindles%20Motors%20and%20Inverters/Colombo%20RV90%205HP%20Collet%20Spindle.pdf
05:46 PM elbartek: it would probably still run on tri phase 220v from vfd no??
05:46 PM * JT-Shop wanders inside to start chow
05:46 PM elbartek: thanks gloops... but they seem to make custom motors like this one
05:47 PM gloops: i dont know, wouldnt want to give advice that burnt an expensive part
05:47 PM elbartek: nameplate: 380v, 400hz, 24000rpm, 2.9kw, 7hp, 7A type 90.2
05:47 PM Valen: some (many) motors can be converted between star and delta wiring
05:47 PM Valen: then a regular VFD will be able to drive it
05:48 PM elbartek: I guess I would have to dissassemble it then...
05:48 PM Valen: (single in > 3 phase out)
05:48 PM Valen: the ones I've seen it's just an electrical connection in the junction box on the motor
05:48 PM elbartek: I can buy a VFD for 220v single and 220v tri out
05:48 PM gloops: the vfd will supply 3 phase to the spindle
05:48 PM elbartek: stupid chinese sell huanyong VFD that does 220v single to 380v triple out... lol... really?
05:49 PM elbartek: doesnt even compute...
05:49 PM elbartek: 220v * sqrt(2) approx 310v ... I guess
05:49 PM elbartek: how the hell they get 380v without a transfo?
05:49 PM elbartek: plus the losses
05:50 PM elbartek: at 5kw that is
05:50 PM elbartek: and 350$
05:50 PM elbartek: lol
05:51 PM elbartek: I was thinking that if I run it a 220v tri phase, only the torque will be affected? it has passive fan cooling, so as long as I get the RPM high, there shouldn't be a problem... no ?
05:52 PM gloops: whats it for cutting?
05:54 PM elbartek: just engraving probably... maybe aluminum cutting too?
05:55 PM elbartek: cutting/engraving copper pcb
05:55 PM elbartek: fr4
05:56 PM elbartek: I know its probably way over specs... but I got the motor
05:56 PM elbartek: HP wise
05:56 PM elbartek: I just want to buy a chinese spindle and get crap runout
05:57 PM elbartek: then I would get a diff. spindle for wood...
05:58 PM elbartek: rewiring from delta to star would lower the voltage requirement?
06:00 PM gregcnc: Probably intended to run from 400V
06:00 PM gregcnc: if you can change it
06:00 PM elbartek: so Im better off finding a 220 tri-phase spindle?
06:00 PM elbartek: ahhhh
06:01 PM gregcnc: you can run any size VFD from single phase in many cases.
06:02 PM elbartek: yeah but... I only have 220v single phase in my home workshop
06:02 PM elbartek: he motor is rated 380v tri
06:02 PM elbartek: the
06:03 PM gregcnc: i'd stick with 220-250
06:04 PM gregcnc: to make life easy
06:04 PM elbartek: yeah... sucks... I got a licensed electrician friend... how hard is it to install 380 at home?
06:04 PM elbartek: lol
06:05 PM gregcnc: pft in the US? impossible
06:05 PM elbartek: prob. not legal
06:05 PM gregcnc: transformer
06:05 PM elbartek: they actually install a transfo?
06:05 PM gregcnc: legal, but the poco will want like 5-10k
06:05 PM gregcnc: I have 400V trafo
06:05 PM elbartek: aaahh\
06:06 PM elbartek: cant spend that much money to run that motor
06:06 PM elbartek: anyone selling a good quality spindle ? lol
06:07 PM gregcnc: aren't there tons of used commercial router spindles on ebay?
06:07 PM elbartek: not good ones... I need an ER collet or something similar
06:08 PM elbartek: Ive found nice ones, but the shaft end is not collet compatible as is
06:08 PM gregcnc: example?
06:08 PM elbartek: teknomotor... perske... elte... hsd... colombo.. but got different shafts with no threads
06:08 PM elbartek: shaft for saw as an example
06:08 PM elbartek: let me show u
06:09 PM elbartek: I thought this one was good enought
06:09 PM elbartek: https://www.ebay.ca/itm/Teknomotor-High-Frequency-Motor-550028RH-1Kw-18000RPM-165VAC-3-Phase/183126163176?hash=item2aa32b7ee8:g:mB8AAOSwr0ZXORwC
06:09 PM elbartek: 165v on 220v vfd is okay... controlled voltage vfd
06:09 PM elbartek: the price is real good... but look at the shaft end... its meant for saw attachment
06:10 PM elbartek: Ive found some perske with threaded shaft for ER collet... but >500$ cheapest.. and seller doesnt know their "state"
06:11 PM elbartek: the teknomotor... well try finding a shaft adapter? I don't know... possible?
06:12 PM elbartek: then maybe its just better to construct my own spindle and use an ac motor with VFD
06:12 PM gregcnc: only if you know such an adapter was a factory item
06:13 PM elbartek: no... they make that shaft for their saw motors
06:13 PM elbartek: too bad...
06:14 PM elbartek: https://www.ebay.ca/itm/PERSKE-3PH-ELECTRIC-MOTOR-SPINDLE/201978692252?hash=item2f06de429c:g:o1wAAOSw~y9ZDMEb
06:14 PM elbartek: but way too big ...
06:14 PM elbartek: however has ER32 collet lol
06:14 PM elbartek: and cheap
06:15 PM elbartek: 4.8kw
06:16 PM elbartek: "Units are in great condition." isnt very very informative
06:18 PM CaptHindsight: ASK THEM FOR MORE DETAILS /shout
06:18 PM elbartek: good idea... Im trying to find the spec sheet... they seem bulky and might weight too much
06:19 PM Tom_L: JT-Shop, did you use G90 or G91 when you use the fixture offset test?
06:28 PM elbartek: any good online store where I could find used cnc parts / spindles ?
06:30 PM CaptHindsight: elbartek: what location? Canada?
06:39 PM Tom_L: not on a linux box here... if you right click on a symbolic linked file will it show you the original's location?
06:46 PM roycroft: that would be a function of whatever file manager you're using - it would not be a linux thing
06:46 PM roycroft: but ls -l shows the location of the linked file
06:47 PM roycroft: that's a universal thing
06:48 PM roycroft: and if it's a directory, ls -l dirname will show the link, and ls -l dirname/ will show the contents of the directory
08:05 PM gregcnc: skunkworks is that a new lathe?
08:06 PM gregcnc: new to you that is
08:07 PM CaptHindsight: anyone returned a broken Crafstman tool lately?
08:07 PM Tom_shop: to where?
08:08 PM gregcnc: sears?
08:08 PM CaptHindsight: do you still just bring them in for a swap? Farm and Fleet, Ace hardware Loews etc
08:09 PM gregcnc: i was wondering the same, should have gone to the sears before they closed it
08:09 PM CaptHindsight: guess I'll try Farm and Fleet and report back
08:09 PM CaptHindsight: just wore out a 3/8 drive
08:09 PM CaptHindsight: has only one spot where it still enagages
08:09 PM gregcnc: oops
08:12 PM elbartek: <-- looking for >18k rpm 220-240v spindle motor which is not chinese
08:12 PM elbartek: I mean... at a good price
08:13 PM elbartek: with ER type collet
08:15 PM malcom2073_: CaptHindsight: Lately sears was giving me rebuild kits for my ratchets
08:15 PM malcom2073_: rather than swapping them
08:15 PM malcom2073_: I mean it worked, but meh on me having to spend the time to rebuild them myself
08:18 PM gregcnc: https://youtu.be/M38EsctrUb0?t=47s
08:42 PM skunkworks: gregcnc, ?
09:19 PM CaptHindsight: farm and Fleet will swap your craftsman tool
09:20 PM CaptHindsight: unfortunately the one near me does not carry the wrench that broke :(
09:20 PM CaptHindsight: wild goose chase continues tomorrow
10:05 PM Tom_L: oh.. what about ACE hardware? they carry craftsman
10:09 PM Jymmm: So does ORCHARD, and *maybe* lowes
10:11 PM Jymmm: CaptHindsight: YOu can call craftsman and they can resolve it for you
10:12 PM Jymmm: CaptHindsight: https://www.craftsman.com/
10:13 PM Jymmm: CaptHindsight: 888-331-4569
10:16 PM CaptHindsight: off to ACE tomorrow
10:16 PM CaptHindsight: they have it in stock near me at 3 different stores
10:17 PM CaptHindsight: how did Sears ever mismanage themselves into oblivion?
10:18 PM CaptHindsight: the ACE website has better search than the Craftsman site BTW
10:19 PM CaptHindsight: https://www.craftsman.com/products/craftsman-3-8-in-drive-flex-head-quick-release-teardrop-ratchet
10:22 PM CaptHindsight: Dear Craftsman Tools, Please make my socket drive more better. I only used it on Sundays to just snug up loose nuts and bolts. No real pressure was applied.
10:28 PM Tom_L: did you drive it with a 1" industrial impact wrench?
10:29 PM CaptHindsight: I noticed it slipping while loosening some 16mm nuts
10:30 PM Tom_L: fine or coarse ratchet? the fine ones strip pretty easy
10:30 PM CaptHindsight: firts 20 deg, then 30 then 60 ... now 180
10:30 PM CaptHindsight: fine
10:30 PM Tom_L: could just be dirty too, did you take it apart?
10:30 PM CaptHindsight: think it's a 10 or 20 between
10:31 PM CaptHindsight: no it slips, not dirty
10:31 PM Tom_L: got your knuckles all taped up now?
10:31 PM CaptHindsight: I usually only break the 1/2 drives
10:31 PM CaptHindsight: hah, i use my teeth, learned that lesson !
10:32 PM Tom_L: i use an 8' cheater bar on my snapon 1/2"
10:33 PM CaptHindsight: I have a 3/4 and 1"set as well
10:33 PM Tom_L: i've never needed one yet
10:33 PM hazzy-dev: I have a late 70s craftsman .375 ratchet that works like new, even though the chrome handle is worn down from years of use, I have a 02 ish craftsman pro .375 ratchet that barley gets used at all, and has been exchanged three times, that is what happened to craftsman ...
10:33 PM CaptHindsight: yeah, the old metal was more better
10:33 PM Tom_L: i believe that
10:34 PM hazzy-dev: HF crap is better than craftsman these day, sad times
10:34 PM Tom_L: for one time use maybe
10:35 PM CaptHindsight: I got a HF 3/4 to 1/2 adapter, it works
10:35 PM CaptHindsight: I did twist a HF 3/8" extension 180 degrees
10:36 PM CaptHindsight: might have been made from solid lead
10:37 PM CaptHindsight: S-K was a local tool maker
10:37 PM Tom_L: at least it didn't snap in half and smack your arm
10:37 PM CaptHindsight: gone now
10:37 PM Tom_L: they were ok
10:37 PM hazzy-dev: the snapoff stuff from HF is hit or miss, but I keep one of these in the truck and it is great for 12 bucks: https://www.harborfreight.com/38-in-drive-quick-release-ratchet-62287.html
10:38 PM CaptHindsight: lol they should use that as a brand name
10:38 PM CaptHindsight: the $10 orbital sander lasted an hour
10:43 PM hazzy-dev: I keep well clear of anything with a universal motor sold by HF, have not had any problems with their tools with induction motors though
10:43 PM * hazzy-dev knocks on wood
10:44 PM CaptHindsight: I don't have much from them
10:44 PM CaptHindsight: I did try this https://www.harborfreight.com/30-inch-shear-press-brake-and-slip-roll-5907.html
10:44 PM CaptHindsight: got lucky, has been working great
10:47 PM hazzy-dev: Seem to have better luck with the HF stuff that requires more brawn than brains
10:48 PM CaptHindsight: i have to find a 8' press brake
10:48 PM hazzy-dev: Though I went in there the other day to get blue gloves, and their new line of welders caught my eye. look pretty decent actually, I was impressed
10:50 PM hazzy-dev: hydraulic or flywheel type?
10:50 PM CaptHindsight: prefer hydraulic
10:50 PM CaptHindsight: the flywheel types are near free since the insurance co's don't like them
10:53 PM hazzy-dev: That is what I was thinking, I see the flywheel ones all over practically for the taking, but the hydraulic ones are so much lighter and simpler if you don't need something fast
10:53 PM CaptHindsight: though I could probably live with a 48"
10:53 PM CaptHindsight: need to shear full sheets, usually just across
10:54 PM CaptHindsight: and make enclosures
10:55 PM hazzy-dev: So you probably don't need anything very beefy, mostly sheet metal stuff it sounds like
10:55 PM CaptHindsight: https://www.ebay.com/itm/30-Ton-Beckwood-2-Post-2672XX-Hydraulic-Machine-Press-Brake-w-72-X-14-Table/132507885296 needs a pump $800
10:57 PM hazzy-dev: They got two of them, cut the post off one end of each and weld them together and it would be plenty long
10:57 PM hazzy-dev: :D
11:02 PM CaptHindsight: I used to have a sheet metal fab nearby. If I brought the materials they would shear and bend for a few $$
11:13 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/ERROR_Pics/
11:14 PM Tom_L: series of screenshots while trying to get G55 work zero set
11:14 PM Tom_L: i don't know why but turns out it was a z move causing the error
11:14 PM Tom_L: if i moved to the X Y 0 position that would work
11:14 PM Tom_L: if i did a MDI G0 Z0 i got an error
11:15 PM Tom_L: if i did a G1 Z -1 F20, then G28 Z0, then G0 Z0 it would work
11:15 PM Tom_L: i don't understand that behavior
11:16 PM Tom_L: the screenshots are for the active codes and offset values
