12:00 AM Lcvette: I get ya, I will look at it
12:03 AM Tom_L: just trying to prevent another crash
12:03 AM Lcvette: My buddy has been running his machine for a while now and I know he has a dollar more that 12 tools
12:03 AM Tom_L: no worries then
12:03 AM Lcvette: I'm sure he would have said something if he had to require the tool table everyone he changed a tool out
12:03 AM Lcvette: Rewrite
12:03 AM Lcvette: Lol
12:03 AM Lcvette: Too late
12:03 AM Lcvette: Also crashed again
12:03 AM Lcvette: Broke some fingers on the carousel
12:03 AM Lcvette: Lol
12:03 AM Tom_L: i read that
12:03 AM Lcvette: They're proud of those little plastic buggers
12:03 AM Tom_L: as i'm sure they are of the Y trucks
12:03 AM Lcvette: $30 a piece
12:03 AM Lcvette: Surprisingly not much difference
12:04 AM Lcvette: Comparatively soaking for what your getting
12:08 AM Lcvette: Piece of $30 plastic verse $70 precision bearing car
12:08 AM hazzy-lab: Lcvette: Even if you end up having to rewrite the tooltable, that could be don't automagicaly by a script when you enter the tool number in one of the boxes in the screen
12:08 AM Lcvette: Oh sweet
12:08 AM Lcvette: Is there a way to get it from where it remaps the t#?
12:08 AM Lcvette: There's a set section where it does then
12:08 AM Lcvette: A block of numbers
12:15 AM Lcvette: M19 r0 q3
12:15 AM Tom_L: you need to load a couple .py files too i think
12:15 AM Lcvette: I just looked through the remainder for too change and didn't see anything relating to H
12:16 AM Lcvette: Maybe mine just triggers am output to my drive which does the orient procedure
12:17 AM Tom_L: i think so
12:17 AM Lcvette: Then sends out a orient completed signal
12:17 AM Tom_L: pin 31 and 10 iirc
12:17 AM Lcvette: Yup
12:17 AM Lcvette: Lol
12:17 AM Lcvette: Pin 10 is for the lock
12:18 AM Lcvette: ;)
12:18 AM Lcvette: Pretty proud of that one
12:29 AM * hazzy-lab goes to shut down the shop lights and get some sleep
12:29 AM hazzy-lab: gn8
12:38 AM Lcvette: Night hazzy!
12:58 AM fragalot: Hi
01:04 AM CaptHindsight: Caged balls

01:10 AM IchGucksLive: hi all
01:12 AM IchGucksLive: im off 2 garden till later
01:15 AM CaptHindsight: https://thumbs.dreamstime.com/b/german-beer-garden-lindau-germany-may-town-lindau-streets-old-town-entry-typical-town-lindau-69302414.jpg
01:15 AM CaptHindsight: gardening huh
01:22 AM fragalot: CaptHindsight: it's a hard life, but someone's got to do it
01:24 AM CaptHindsight: http://www.3ders.org/articles/20180531-you-can-get-a-3d-printed-model-of-your-brain-in-under-an-hour-thanks-to-bitmap-based-3d-printing.html
01:24 AM CaptHindsight: ...... if they can find it
01:26 AM fragalot: I'm kinda amazed this didn't exist already
01:26 AM fragalot: the conversion technique, I mean
01:27 AM XXCoder: nice
01:27 AM CaptHindsight: have to get raw MRI data
01:27 AM CaptHindsight: things like that get turned into proprietary formats rather quickly
01:28 AM CaptHindsight: you don't want and upstart outdoing your highly profitable imaging
01:28 AM CaptHindsight: and/an
01:52 AM CaptHindsight: https://lifesciences.solutions/bioassemblybot/
01:52 AM CaptHindsight: they have software to convert MRI scans into robot paths
01:53 AM CaptHindsight: maybe i should do it for LCNC
01:54 AM CaptHindsight: https://lifesciences.solutions/tsim/
02:23 AM Loetmichel: hmm... anyone knows of a downloadable DVD label for LinuxCNC 2.7.1? If so, please share the link!
02:25 AM XXCoder: easy enough to make one
02:25 AM XXCoder: download vector image of Chip, add version #
02:27 AM Deejay: moin
02:35 AM Loetmichel: XXCoder:could do...but would take time... used a sharpie for now ;)
02:36 AM XXCoder: lol ok
02:37 AM Loetmichel: <- still has problems with his maschine losing steps on y under very certain curcumstances. repeatable. so i dont think its a loose contact, i am thinking LinuxCNC is "forgetting" acceleration ramps. so it may be a good idea to update to the newest version and see if that helps ;)
02:38 AM XXCoder: odd. yeah hope you figure it out
02:38 AM CaptHindsight: https://postimg.cc/image/fdot1h5g1/
02:44 AM Loetmichel: hmm... "linuxCNC 2.6.13" exactly one minor version point behind... maaan, that system is ooold...
02:45 AM Loetmichel: where did i store that external disk? better making an image before reinstalling it to 2.7.13 ;)
02:51 AM RyanS: Ich mentioned that running steppers at 80V ( instead of 45V) increases the costs of EMI shielding. why is that? more expensive cables and enclosures?
02:56 AM rmu: RyanS: i don't know about EMI shielding, but 80V is above "extra low voltage", so regarding regulations 80V is as good as mains voltage
02:56 AM CaptHindsight: more shielding costs mire
02:57 AM CaptHindsight: higher voltage, higher energy noise
02:58 AM CaptHindsight: depends on the design of the stepper drivers
02:58 AM RyanS: I was thinking it is more because we were talking about plasma but you would need good shielding regardless of the stepper voltage
03:00 AM CaptHindsight: it's an odd idea to bring up
03:00 AM CaptHindsight: cnc plasma cutters don't require higher voltage steppers
03:01 AM CaptHindsight: https://www.allaboutcircuits.com/tools/stepper-motor-calculator/
03:02 AM CaptHindsight: http://www.daycounter.com/Calculators/Stepper-Motor-Calculator.phtml
03:03 AM syyl: https://kaindl.de/en/fsm.html?___from_store=de
03:03 AM syyl: commercial cnc grinder that uses linuxcnc
03:04 AM CaptHindsight: RyanS: are you considering using some large steppers that require higher 80V
03:04 AM CaptHindsight: RyanS: was the discussion about noise with a THC for plasma?
03:05 AM RyanS: well, I want 7800mm/min (310 ipm) and I think you want as much acceleration as possible. so I was thinking higher voltage = more torque = faster acceleration
03:06 AM XXCoder: so if I feed stepper 1000v would it have insane level of torque?
03:06 AM CaptHindsight: RyanS: yes you want to use proper grounding techniques
03:06 AM CaptHindsight: and smoke
03:06 AM XXCoder: so theres voltage limit
03:07 AM CaptHindsight: the insulation of the coil windings is one hard limit
03:08 AM CaptHindsight: the power supply input to the stepper drivers is another
03:08 AM XXCoder: ahh makes sense. hugher voltage need more isulation and grounding
03:08 AM RyanS: the torque curve is higher at 80V than 40v and most drives are 50v or 80v from what I've seen
03:09 AM CaptHindsight: but you're not driving steppers at anywhere near the breakdown voltage of the insulation
03:09 AM RyanS: and most builds use NEMA 34 which won't cost me any more than 23s really
03:10 AM CaptHindsight: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Formulas
03:10 AM CaptHindsight: XXCoder: ^^
03:10 AM XXCoder: looking
03:11 AM rmu: higher voltage makes the current increase faster, current is proportional to torque, so increasing voltage can increase performance of stepper with high speed
03:11 AM CaptHindsight: power dissipation of the motor is another limit
03:12 AM rmu: doesn't matter that much when stepping speeds are low
03:12 AM RyanS: I'm pretty sure shielded stepper cables can take a lot of emi
03:12 AM XXCoder: 60c recommanded as limit
03:12 AM XXCoder: (stepper heat
03:12 AM rmu: power dissipation should be that much different as the drive has to control current anyway
03:12 AM rmu: should NOT be
03:14 AM CaptHindsight: XXCoder: but yeah a million volts would be more torque :)
03:14 AM XXCoder: turn the world ;)
03:14 AM CaptHindsight: if it didn't arc and melt
03:15 AM CaptHindsight: like saying a 250,000 hp engine would make a car faster
03:16 AM CaptHindsight: if it was 300Kg and fit and didn't melt
03:17 AM XXCoder: shuttle carrier has insane HP and can carry shuttle and stuff ready to launch, yet it goes at max speed of 4 mph
03:17 AM CaptHindsight: yah just needs a differnt tranny
03:18 AM CaptHindsight: fer more giddyup go
03:18 AM XXCoder: lol
03:18 AM RyanS: am I asking for headaches going closed loop steppers? does linuxCNC need to be set up differently to using open loop?
03:23 AM CaptHindsight: no, it's a different config, closed vs open loop
03:24 AM RyanS: ie more things to go wrong
03:25 AM CaptHindsight: what type of encoders?
03:25 AM CaptHindsight: glass scales, rotary on the motor shafts?
03:25 AM RyanS: rotary
03:26 AM CaptHindsight: plasma cutters are non-contact
03:26 AM CaptHindsight: what will the travels be?
03:27 AM RyanS: 1200mm
03:28 AM RyanS: 435mm/min to 7800mm / min range preferably
03:28 AM CaptHindsight: rack and pinions for the XY?
03:28 AM RyanS: yeah
03:46 AM gloops: fragalot got closed loop steppers and has had them running i think, he might be able to explain the config
03:47 AM Loetmichel: *hmpf* 2 hours into work.. day already shit. 5 projects that had fails over the weekend... so i have to attend to them and "repair" the problems... atm i am running around like a chiken that just lost its head... i HATE multitasking...:-(
03:47 AM gloops: there is a loop between the driver and stepper to ensure commands are executed
03:49 AM gloops: you can also use encoder input to detect following errors in linuxcnc, and..i think you have 2 way signals which will give absolute position, like a servo
03:49 AM gloops: you can have 2 way signals
03:50 AM RyanS: ok
03:51 AM RyanS: anyone tried the drives from Stepperonline?
03:53 AM gloops: i think ive had 1 driver, wasnt a genuine leadshine i dont think, works ok though
03:55 AM RyanS: they used to sell 'leadshine' but now they just have their own brand
03:56 AM gloops: well, the one i got was leadshine price, but when it came it was just a chinese copy with stepperonline print on it
03:56 AM gloops: they work pretty much the same
03:58 AM RyanS: interestingly Kelling drives have an identical manual to leadshine so those could simply be manufactured for Kelling
04:02 AM gloops: i dont know how it works in Aus, over here its often cheaper to buy a bundle than individual parts
04:02 AM gloops: motors/drivers/psus all together
04:04 AM gloops: https://www.ebay.co.uk/itm/DE-SHIPPING-Wantai-CNC-kit-3Axis-Nema-34-Stepper-Motor-1232oz-in-5-6A-Driver-80V/152308752022?
04:04 AM RyanS: my only concern is how to identify an issue with a drive but at the same time a local supplier wants $170AUD for leadshine DM556
04:05 AM gloops: pfff
04:06 AM RyanS: see I don't get the power supply for each driver thing
04:07 AM RyanS: I would rather get one decent meanwell PSU
04:10 AM gloops: well, the argument is individual psus dont get overloaded
04:10 AM gloops: if all axis are moving at once, fast maybe, the one psu gets hit
04:11 AM Loetmichel: gloops: argument for one big psu could be that it can provide more current o ne axis whenthe otehr ones doesent use as much
04:12 AM gloops: i noticed a 'bit' of difference when i went to 2 psus
04:15 AM gloops: if you have 1 psu per motor, that can handle any demand the motor makes, youre safe
04:37 AM RyanS: none of these cheapo motors have torque graphs
05:11 AM Loetmichel: sooo, installed newest version of LinuxCNC on the mill/router... here is hoping that the "forget acceleration ramps occasionally and destroy workpieces" is gone now :)
05:28 AM RyanS: ok so nema 34 at 48V is 400RPM and at 80V is 600RPM
05:37 AM rmu: RyanS: i know of nema34 stepper motor doing 1000rpm @ 80V, moving a gantry via timing belt at about 1m/s
05:38 AM rmu: IME thats pretty much the limit what is possible with steppers
05:40 AM RyanS: god... I only need 7m/min
05:40 AM XXCoder: https://www.youtube.com/watch?v=qNzl6N_ScyQ monowheel bike
05:43 AM gloops: to get the high speeds though the drivers need to be fast, and the step generator
05:44 AM gloops: or, you are likely to run into step timing problems or latency long before you get to 60m/min ?
05:44 AM gloops: with parport
05:47 AM rmu: gloops: in this case it is dedicated µ-controller that is generating the steps, up to about 35kHz
05:47 AM Loetmichel: hmmm... not getting the steppers enabled... LinuxCNC runs, but no movement at all, not even in the stepconf wizard... and i used the wizard file from 2.6.13... where did i go wrong???
05:48 AM Loetmichel: no changes to hardware made, just a fresh install from the 2.7.13 DVD...
05:48 AM Loetmichel: Any ideas?
05:49 AM gloops: not found parport?
05:49 AM rmu: Loetmichel: polarity mismatch on enable signal, missing/wrong charge pump settings, wrong EPP setting in BIOS
05:57 AM Loetmichel: HA! Found it!... it can be so simple... managed to reset the bios to defaults while installing... default is: LPT and com-ports off... :-(
05:57 AM Loetmichel: somehow
05:57 AM XXCoder: weird
05:57 AM Loetmichel: no idea how that happened though
05:57 AM Loetmichel: that bios reset
05:58 AM XXCoder: battery died for a minute or what
05:58 AM RyanS: ah so 80V, 3.5L, 5.5A gives about 600 rpm. 2*pi*(rps) = 0.36 m/s / 3 for 3:1 belt reduction is 7200mm/m. does that sound right?
05:58 AM Loetmichel: nope, PC wasnt off today
05:58 AM Loetmichel: so it cant be the battery
05:58 AM RyanS: with a 10mm pinion
05:59 AM Loetmichel: i suspect the wrong Thumbdrive with won10 install on it that i accidently booted from instead of the LinuxCNC DVD
05:59 AM Loetmichel: win10
05:59 AM Loetmichel: its an old Core2 duo 2800 and an industrial board though
06:00 AM Loetmichel: can sometimes react strangely to "newer" OSes
06:01 AM Loetmichel: its surprisingly powerful though... less than 10k jitter, even with streaming a webcam and desktop to a different pc for remote operation... -> https://www.youtube.com/watch?v=9u_ChO1AKYY
06:02 AM Loetmichel: works the same with the new version (at least it did with the 2.6.13 install)
06:02 AM XXCoder: thats lower than my 11? years old pc lol
06:06 AM jthornton: morning
06:06 AM Loetmichel: lower jitter or lower cpu power?
06:07 AM Loetmichel: morning
06:07 AM XXCoder: jitter
06:07 AM XXCoder: dunno on cpu
06:07 AM XXCoder: it was fairly high end back then. 8 gb ram along other stuff
06:10 AM jthornton: hmm there is a toad in the run...
06:10 AM XXCoder: this one? heh https://www.youtube.com/watch?v=dCnjgAkDXvk
06:12 AM jthornton: lol
06:14 AM XXCoder: :)
06:15 AM jthornton: I've seen the neighbors chickens eating a frog but mine have ignored the toads
06:17 AM XXCoder: chickens eat whatever they can or feel like I guess lol
06:19 AM jthornton: once they figure out it's food then the battle is on
06:23 AM Tom_L: morning
06:26 AM XXCoder: world sharpest cardboard https://www.youtube.com/watch?v=jvo86AHovFc
06:27 AM XXCoder: carbon knife still #1, followed by pasta knife
06:35 AM syyl: oh
06:35 AM syyl: they are making a prison shiv
06:36 AM miss0r: syyl: I got the correct Erowa chuck. I needed a manual one
06:36 AM syyl: perfect :)
06:36 AM syyl: that means that i can leave for work, without worrying ;)
06:36 AM syyl: ahoi!
06:36 AM miss0r: and it turns out a former employee, who is VERY local to me, had it in his new shop. So I just drove there and got it
06:36 AM miss0r: :o
06:44 AM Tom_L: https://www.youtube.com/watch?v=TRjm3FsApOg
06:44 AM Tom_L: the reason i posted this is at 2:00 approx, what sort of shell mill is that?
06:44 AM Tom_L: cuts both directions
06:45 AM Tom_L: maybe it's my imagination but it looked like it reversed direction
06:46 AM Tom_L: i think it's just the camera sync and the spindle speed making it look that way
06:47 AM miss0r: If you look at the way it throws the chips, its a regular one
06:48 AM Tom_L: still waking up here, wasn't thinking about that :)
06:48 AM miss0r: ;]
06:51 AM Tom_L: is that a thread form tap at 4:53?
06:52 AM Tom_L: kinda surprised they use no coolant there
06:54 AM miss0r: Looks like a solid carbide tab.
06:54 AM miss0r: They most likely turned off the flood coolant to allow for footage.
06:54 AM Tom_L: sometimes it's on though
06:54 AM miss0r: Otherwise that would be a quite boring operating to look at
06:54 AM miss0r: sure
06:55 AM XXCoder: yeah. it eats tools but for single video shot its fine
06:55 AM XXCoder: while some it would probably fuse with part if no coolant lol
06:55 AM miss0r: I'm breaking my neck trying to find a rockwell automation server: B3633-3Y+1000LD+TRIAD+25WAY D
06:55 AM miss0r: Any of you living in the US?
06:55 AM miss0r: server=servo
06:56 AM Tom_L: https://www.ebay.com/itm/Rockwell-Automation-Motor-Model-B3633-3Y-1000LD-TRIAD-25WAY-D-/272526981159
06:56 AM XXCoder: usa
06:56 AM miss0r: I have found a seller; he lives in the US, but does not sell to international buyers
06:56 AM miss0r: Tom_L: exactly that one
06:56 AM miss0r: and I don't have the time to wait a month for one from yo long ding dong
06:58 AM miss0r: XXCoder: Are you from usa?
06:59 AM miss0r: anyway; if somewhat wants to help me out here. I will paypal upfront & pay for every possible expense assosiated with this transfer
06:59 AM XXCoder: yeah though not shipping though, way too busy :(
07:00 AM XXCoder: hope you find someone. :) there is reshippers service out there I think
07:00 AM miss0r: hmm.. Will look into that
07:02 AM XXCoder: I bet that video? its been setup a while ago and system locked
07:02 AM XXCoder: I bet it's a nightmare to setup
07:13 AM Loetmichel: XXCoder: It works again... so far no step loss on y... -> (caution loud) https://www.youtube.com/watch?v=zkcJXdLp-ms
07:13 AM XXCoder: my pc dont even have speakers lol
07:14 AM XXCoder: using autovomit video smoother in youtube?
07:14 AM miss0r: woah. getting seasick here
07:15 AM Loetmichel: XXCoder: you mean "i should" or "did i have used"?
07:15 AM XXCoder: *should not have used* ;)
07:15 AM Loetmichel: ah, so its most likely "should have"... sorry, freehand with a smartphone
07:15 AM Loetmichel: XXCoder: i havent used one
07:15 AM XXCoder: ahh yeah some phones have weird latency with videos
07:15 AM Loetmichel: its uploaded directly from the smartphone
07:16 AM XXCoder: makes it have siiliar effect but not as bad as youtube autovomit video stabilizer
07:16 AM miss0r: But that was like the worst kind of latency.. The one you have no chance of predicting. It gave me the sweats
07:16 AM XXCoder: anyway it seems to run smopthly
07:17 AM XXCoder: miss0r: trust me, im way too riciously sensive to handheld and his wasnt too bad for that
07:17 AM Loetmichel: XXCoder: if you mean the sprinle shaking at the start: thats the whole "table" it sits on moving left and right
07:17 AM miss0r: XXCoder: i'm usualy not sensitive to it, but that one there got me :D
07:17 AM XXCoder: no, whole video
07:17 AM Loetmichel: newtons forst law ;)
07:18 AM XXCoder: I miss gaming. :( though minecraft is starting to return to "playable"
07:18 AM Loetmichel: ah, sorry. s/first/second
07:18 AM XXCoder: I can only do very limited mining or even explore interiors
07:19 AM XXCoder: but "outside" is fine.
07:19 AM RyanS: newton's first law = apples hurt when they hit your head
07:20 AM Loetmichel: second: each force has a direct and opposite force
07:20 AM Loetmichel: because spindle and y axis has higer mass than the rest of the table it moves the table instead of the spindle ,)
07:20 AM miss0r: RyanS: Newtons 4th law: for every made action, there a female overreaction
07:21 AM * XXCoder rolls eyes
07:21 AM Loetmichel: resulting in that "swaying2 motion
07:21 AM RyanS: shit has friction. is that one?
07:21 AM miss0r: hehe
07:23 AM miss0r: During this cleaning, the EDM installation has forced me to do: I found some fun stuff :)
07:24 AM miss0r: When the misses and I bought this house 6 years ago, it was sold 'as is'. I.e. the former owners were dead, and there was noone to enherit the stuff. So needless to say we did a lot of back and forward to the local recycling station. But I also kept some tools. I am quite sure he owned some milling equipment of some sort
07:24 AM miss0r: I just stumbled across one of those boxes, that I tucked away. Some of these tools i've never seen before
07:25 AM XXCoder: nice
07:48 AM RyanS: does it matter if they don't show the torque curve? https://www.omc-stepperonline.com/nema-34-stepper-motor/keyway-dual-shaft-nema-34-cnc-stepper-motor-45nm-637ozin-55a-86x86x80mm-34hs31-5504d.html
07:49 AM RyanS: the stepper calculator says 411rpm @ 48V
08:02 AM miss0r: meh.. i just ordered 120L dielectric fluid for the "new" edm. 4.30eur/L
08:03 AM miss0r: This is turning out to be an expensive friendship
08:04 AM miss0r: Its basically kerosine, but with the flame point at a higher temperature than regular kerosine
08:54 AM Lcvette: Tom_L: the tool numbers are stored in the linuxcnc.var file
08:55 AM Lcvette: I checked and when changing tools there does not appear to be an issue of having more than 12 tools in the tool table, the H offset does follow the T# during an m6
08:56 AM JT-Shop: miss0r: if you want to ship the motor to me I can forward it to you, I ship international all the time from my Mesa store
08:56 AM Lcvette: So that f wouldn't be an issue
08:57 AM Lcvette: *shouldn't
09:00 AM gregcnc: H offset is whatever you call
09:00 AM gregcnc: machine doesn't care if it's T1 H99
09:02 AM Lcvette: There were some questions last night as to whether there h offset from the tool table would follow the tool number or pocket number during a tool change
09:02 AM gregcnc: it doesn't
09:03 AM gregcnc: Most CAM however do this be default
09:03 AM Lcvette: Shouldn't have to have offsets in cam
09:03 AM gregcnc: in you are fingerCAM, you have to call the correct offset
09:03 AM gregcnc: yes you do
09:03 AM Lcvette: No
09:04 AM gregcnc: absolutely
09:04 AM Lcvette: Usually in machine
09:04 AM gregcnc: which cam do you use
09:04 AM Lcvette: Can be done either way
09:04 AM gregcnc: ofsset values are stored in the machine
09:04 AM Lcvette: But makes no sense to have to update a programmer with tool offsets
09:04 AM gregcnc: offset are called in cam just like manual programming
09:05 AM Lcvette: They specify what tool
09:05 AM gregcnc: and which offset to use
09:05 AM Lcvette: No
09:05 AM Lcvette: Sorry
09:05 AM gregcnc: the offset number doens't have to match the tool noumber for any reason other can convenience
09:06 AM gregcnc: you've never used it any other way I. I on the other hand have
09:06 AM Lcvette: A length offset is not going to stay the same
09:07 AM Lcvette: A machine operator isn't going to remeasure and set his tools Everytime a program comes down the line
09:07 AM gregcnc: tha'ts not eh question here
09:07 AM Lcvette: Sure it is
09:08 AM Lcvette: If your saying can dictates the offer
09:08 AM Lcvette: Cam* offset
09:08 AM gregcnc: no
09:09 AM Lcvette: The offset sould be does in the machine
09:09 AM gregcnc: the value in the offset register is one thing, and calling the offset to use with a tool is another
09:09 AM Lcvette: Stored
09:11 AM gregcnc: does that make sense?
09:11 AM Lcvette: None at all
09:12 AM gregcnc: what kind of amchines have you run?
09:12 AM Lcvette: There's only one correct offset unless your using an offset compared to a master tool
09:12 AM gregcnc: there are a variety of reasons to use different offsets
09:12 AM gregcnc: or different values for the smae tool
09:13 AM gregcnc: do you have a copy of the SMid book?
09:13 AM Lcvette: wear offset
09:15 AM gregcnc: some controls have wear, but that's not relevant
09:16 AM gregcnc: you don't call wear separately
09:16 AM Lcvette: Ok your missing the waters here I think
09:16 AM Lcvette: Missing
09:16 AM Lcvette: Muddying
09:16 AM gregcnc: dude I actually use controls with wear, and often call an offset that is not the tool number
09:17 AM gregcnc: it's very common
09:17 AM Lcvette: There's no chance I'm calling my offers from cam
09:17 AM gregcnc: even standard practice
09:17 AM gregcnc: post some code and i'll show you
09:17 AM gregcnc: which cam do you use?
09:19 AM Lcvette: Wait
09:19 AM Lcvette: Wait
09:19 AM Lcvette: We are talking about the same thing in different ways
09:19 AM Lcvette: Yes
09:19 AM Lcvette: Hxx comes from cam
09:20 AM Lcvette: As a started call
09:20 AM gregcnc: that is calling the offset
09:20 AM Lcvette: But the value assigned comes from linuxcnc
09:20 AM Lcvette: That's what we were discussing here
09:20 AM gregcnc: value is in the control, which can be anything and doesn't matter
09:20 AM gregcnc: no
09:21 AM gregcnc: you MUST call the offset
09:21 AM Lcvette: Not you and I dammit
09:21 AM gregcnc: that is the point I'm making
09:21 AM Lcvette: Tom and i
09:21 AM Lcvette: Lol
09:21 AM gregcnc: T1 H99 is valid
09:21 AM Lcvette: Last night
09:22 AM gregcnc: by default CAM usually calls T1H1, but tha'ts because you madeCAM do that
09:22 AM Lcvette: Ok
09:22 AM Lcvette: Go back to the log and read from last night
09:22 AM Lcvette: Then come back
09:22 AM Lcvette: If you want to continue
09:22 AM gregcnc: My CAM is setup to call T1 H11 for my Fanuc M0 control
09:23 AM Lcvette: So already I'm not arguing the h word
09:23 AM Lcvette: I'm seeing the assigned offset value
09:23 AM Lcvette: That's not coming from cam
09:24 AM Lcvette: The married value
09:24 AM Lcvette: Measured
09:24 AM Lcvette: Your beating a read horse
09:24 AM Lcvette: Dead
09:24 AM gregcnc: Oh, I went over that with him a while ago
09:24 AM Lcvette: And will it didn't stick
09:24 AM Lcvette: Lol
09:25 AM Lcvette: Well
09:25 AM Lcvette: Damn tablet
09:25 AM Lcvette: He was saying he thought the h values would follow the pocket number not the tool number
09:25 AM Lcvette: In the ATC setup
09:26 AM Lcvette: Because there are only 12 pockets and more than 12 tools in my tool table
09:26 AM Lcvette: But that's not an issue I told him
09:26 AM Lcvette: He said to check
09:27 AM Lcvette: Not being so don't in linuxcnc I figured better safe than sorry even if skeptical
09:27 AM Lcvette: So I researched it
09:27 AM Lcvette: Was just reporting my findings
09:32 AM Lcvette: Now in a perfect world,, the machines on the floor would be networked to the cam work stations and the tlo's would be updated in realtime and adjusted in the tool library in can do the cam programme
09:33 AM Lcvette: Always has 100% accurate tooling simulation to work with for collision and gouge deyection checking
09:33 AM gregcnc: some places do
09:34 AM Lcvette: I know
09:34 AM Lcvette: Is awesome
09:49 AM Tom_L: glad we cleared that up...
09:50 AM rmu: Lcvette: you want something like https://www.wfl.at/en/software/crashguard
09:53 AM Tom_L: i bet that
09:53 AM Tom_L: 's mostly used on 5 axis etc
09:54 AM gregcnc: where the cost is worth the benefit
09:59 AM IchGucksLive: hi all
09:59 AM Tom_L: hi
10:00 AM IchGucksLive: Lcvette, sounds like Factory 4.0
10:01 AM IchGucksLive: Inneoi ProE got all you need
10:02 AM Lcvette: Lol
10:02 AM Lcvette: I'm good with fision
10:02 AM Lcvette: Fusion
10:03 AM Lcvette: Works for now
10:03 AM Lcvette: Affordable
10:08 AM IchGucksLive: Lcvette, why not Freecad
10:09 AM Lcvette: Maybe
10:09 AM Lcvette: But for now I'm familiar with what I'm using
10:09 AM Tom_L: IchGucksLive how's freecad doing?
10:10 AM Lcvette: No need to add more confusion or learning curve to my sissy fill plate
10:10 AM IchGucksLive: only a view noe on it and most internal
10:10 AM IchGucksLive: Tom_L, my trodoichanal is not accxepted as discussion saing it schoudt be a full operation base
10:10 AM Lcvette: Once all my other to do's are done I will have a look at freecad
10:27 AM IchGucksLive: im off
11:47 AM Tecan: https://cdn.thingiverse.com/renders/41/27/50/7e/2c/d6f6ba9bda853804535affdbcf588ffa_preview_featured.jpg
11:50 AM hazzy-lab: Tecan: What CAD are you using?
11:54 AM miss0r: tecan: and what the hell is that thing?
12:05 PM skunkworks: Tecan: what is it?
12:05 PM hazzy-lab: Part of his 3D printer :)
12:06 PM Tecan: yeah, looks handy
12:06 PM hazzy-lab: looks like a stealth aircraft though
12:06 PM hazzy-lab: :D
12:07 PM Tecan: im making a new block thats printable without supports
12:07 PM Tecan: almost done
12:07 PM hazzy-lab: nice
12:11 PM Tecan: https://cdn.thingiverse.com/renders/47/d9/4c/e2/f4/437c929426336198acb71892e6dcbb5b_preview_featured.jpg
12:12 PM Tecan: there got rid of the flat spot under the stepper mount
12:13 PM IchGucksLive: hi all
12:18 PM aircooled is now known as hazzy-lab
12:18 PM hazzy-lab: here lazzy log: http://tom-itx.no-ip.biz:81/~tom-itx/irc/logs/%23linuxcnc/2018-06-18.html
12:18 PM hazzy-lab: :D
12:18 PM hazzy-lab: lol
12:19 PM hazzy-lab: I beat a bot for once!
12:24 PM miss0r: hazzy-lab: check out my new EDM: https://imgur.com/a/PfPuNdq
12:25 PM hazzy-lab: miss0r: Very nice! Are you going to put the spindle you made on it?
12:26 PM miss0r: no :) This one does it all on its own. The spindle if for the portable EDM
12:31 PM hazzy-lab: Ah, I noticed the stand the spindle was mounted on, I figured it was just for testing, but it is portable! That would be very handy for removing broken taps and the like on larger work
12:31 PM hazzy-lab: So do you have a portable power supply too?
12:33 PM miss0r: well.. portable sure :) it weighs 15 kgs
12:33 PM miss0r: but it is build with a handle on it, so thats the idea
12:39 PM hazzy-lab: Thats not too bad, about like a small welder ..
12:40 PM hazzy-lab: Certainly more portable than a normal EDM power supply!
12:43 PM miss0r: absolutly. this not quite new one I bought (1982) weighs 125 kgs
12:43 PM miss0r: (the power supply alone)
12:53 PM IchGucksLive: miss0r, time changes and 1982 is the start of mashine builders
12:53 PM miss0r: Its a good year for that stuff ;)
12:57 PM IchGucksLive: miss0r, most education here still runing this mashines
12:57 PM IchGucksLive: miss0r, i fixed alot of thme in the past 10 years
12:57 PM miss0r: Indeed. It is still used as a tool room EDM in the industry here as well
12:58 PM IchGucksLive: but most is the control down no mechanikal failure
12:58 PM miss0r: Indeed. I hope this unit is OK. but I won't know for the next 14 days. I don't have enough dielectric fluid for it before then
12:59 PM IchGucksLive: im off for today bye Gn8
12:59 PM Rab: miss0r, what's the composition of the fluid?
01:00 PM miss0r: A proprietary blend of eleven herbs and spices
01:00 PM Rab: (Apologies if you've already discussed this)
01:00 PM miss0r: hehe. well, its basically kerosine, but with a higher flame temperatur. if you don't use the 'improved' kerosine, your fire ensurance will go through the roof
01:01 PM Tom_L: as will everything else
01:02 PM Rab: I knew kerosene was a staple for EDM, but I wondered about that.
01:02 PM miss0r: With some amount of certainty, yes :)
01:02 PM miss0r: well. kerosine is alright in its pure form, as long as you make damn sure to keep the sparking well below the surface
01:02 PM Tom_L: don't try this at home, we are trained professionals
01:02 PM miss0r: (we get payed to do this=
01:02 PM miss0r: )*
01:02 PM gregcnc: it's probably a bit more like lamp oil
01:03 PM miss0r: probally.. i hope its something else:D it was expensive enough
01:03 PM Tom_L: mythbusters did a flame test episode and i think kero was one that was very hard to ignite
01:04 PM miss0r: sure. but keep in mind, if conditions are not ideal for sparking, you might have a pocket of hot kerosine surrounding the electrode. AND should the same poor fluid exchange also cause a lowered surface, you have you recepie for dissaster
01:11 PM skunkworks: flash point!
01:13 PM miss0r: yes, thanks ! :D
01:15 PM Loetmichel: kersone is close to diesel
01:15 PM Loetmichel: it doesent ignite at all without either a wick or an atomizer
01:15 PM Loetmichel: at room temperature that is
01:16 PM Loetmichel: but in an EDM there can not happem much
01:16 PM Loetmichel: the kerosene bubbles becasue of the sparks have no oxygen in them and they recombine with the fluid before they reach the top
01:17 PM Loetmichel: so even if you have a ignition source there it would not burn
01:17 PM fragalot: 'sup
01:17 PM lcvette_: that all sounds frightening
01:17 PM fragalot: I'm going through an entire bristle cup wheel on my angle grinder per part on this rf45 >.<
01:18 PM miss0r: :o
01:18 PM skunkworks: https://www.youtube.com/watch?v=h4Jj9AYZM0w
01:18 PM fragalot: some parts seem to be filled with plaster that comes off by looking at it, other parts seem to feel like they went old-school & did it with lead
01:18 PM miss0r: realy going at it today, ha?
01:18 PM * Loetmichel uses 99.5% IPA in an ultrasonic cleaner often... THATS fun... one spark on the topand you have a funny sputtering flame about 6"*8" wide on top of the cleaner...
01:18 PM Loetmichel: no problem though, thats why there is a stainless steel lid ;)
01:18 PM fragalot: hehe
01:19 PM miss0r: :D
01:20 PM fragalot: liquid kerosene typically isn't really /THAT/ flammable that a spark sets it off.. until you vaporize it.
01:20 PM Rab: The classic Bondo machine tool restoration?
01:20 PM Loetmichel: fragalot: thats what i just said
01:20 PM Loetmichel: IPA however...
01:20 PM fragalot: Rab: the classic chinese casting clean-up. :P
01:20 PM Loetmichel: (2-propanol, not the beer)
01:21 PM fragalot: Loetmichel: ever time you say IPA it makes me think of indian pale ale and makes me feel ill >.>
01:21 PM skunkworks: I broke down and bought 55 gal of edm oil... It wasn't pretty
01:21 PM skunkworks: And I still haven't really used the edm for anything...
01:21 PM fragalot: miss0r: so was it just kerosene then?
01:21 PM Loetmichel: fragalot: thats why i clarified
01:21 PM Loetmichel: ;)
01:21 PM * djdelorie wonders what kind of edm oil skunkworks finds attractive...
01:22 PM skunkworks: the free kind...
01:22 PM miss0r: fragalot: He had no idea. Apparently the last year of him owning it, it was rented out to another shop, that is now closed(reason he got it back and put it up for sale). So I ordered two 60L barrels of some kerosine based dielectric fluid. But it will take 14 days for it to get here >.<
01:22 PM fragalot: sounds pricey
01:23 PM miss0r: 4.30eur/L
01:23 PM miss0r: plus taxes, plus shipping ect
01:23 PM fragalot: but you get the taxes back
01:23 PM skunkworks: https://www.youtube.com/watch?v=TNfLRVFBF38
01:23 PM miss0r: sure. just not the environmental taxex
01:24 PM gloops: first slot together creation worked, perfect joints, too perfect for idiots to assemble though, thats another string to the fiddle anyway
01:25 PM miss0r: gloops: pictures or it didn't happen ;)
01:25 PM gloops: phones dead lol
01:25 PM fragalot: it didn't happen.
01:25 PM miss0r: it didn't happen.
01:26 PM gloops: the joints are..perfect, needs gentle force with heel of hand to push in, id take a thrape more off if i were to sell them
01:26 PM fragalot: of course they're perfect, they only exist in CAD
01:26 PM miss0r: my my, what an imagination you have :P
01:26 PM gloops: ill post pics tommorrow
01:27 PM miss0r: Looking forward to it ;)
01:34 PM gloops: only a dome slice into 4, only needed 2 parts as theyre identical either way https://ibb.co/guQ3Pd
01:35 PM gloops: it took quite a bit of messing about to work out a way to achieve these using only free software lol
01:35 PM gloops: but now the process is proven, can apply it to any 3d model
01:36 PM Tom_L: https://www.youtube.com/watch?v=IR2p9ceg1bw&t=3s
01:36 PM Tom_L: interesting toe clamps
01:41 PM hazzy-lab: fragalot: been there, done that, wouldn't do it again: https://goo.gl/photos/zY3e6AjbmZQdVFW67
01:41 PM fragalot: nice
01:42 PM hazzy-lab: Is your's a genuine Rong Fu?
01:42 PM fragalot: wow your casting looks even more like styrofoam than mine does
01:42 PM fragalot: no
01:43 PM fragalot: I'm fairly confident mine is a copy of a clone of an RF
01:43 PM fragalot: where someone described it to a 4yr old messenger boy
01:43 PM hazzy-lab: that sounds about right!
01:44 PM miss0r: fragalot: I hope to see yours in as nice & clean a state as hazzy-lab's
01:44 PM JT-Shop: Tom_L: I have a few similar to that
01:44 PM fragalot: miss0r: I'll do you one better, mine's sparkly!
01:45 PM miss0r: hehe, I thought you were trying to get rid of that again?
01:45 PM hazzy-lab: My ENCO was better than the genuine rong fu's we have at Gtech, which was surprising
01:45 PM fragalot: nah, it's growing on me
01:45 PM fragalot: :P
01:47 PM miss0r: hahaha
01:47 PM gloops: harry kane 10 minutes eng 1 tun 0
01:48 PM hazzy-lab: Here are the pics of my RF45 CNC conversion: https://goo.gl/photos/VpBoQXWfCFtgN4mZ8
01:48 PM Tom_L: JT-Shop, i wonder how many hours he put into em
01:49 PM Tom_L: coulda just as easily bought some if you're counting hours
01:52 PM miss0r: hazzy-dev: IS THAT A SPEC OF RUST ON THAT GEAR?! HOW DO YOU EXPECT TO DO PRECISION WORK WITH RUST ON THAT GEAR?! (drill sergent, Full metal jacket) It looks good :D
01:53 PM cradek: it looks like he's leaving the jaws dead hard. I'm surprised they don't just shatter.
01:55 PM hazzy-lab: miss0r: That was some sort of red lapping compound they used to run in the gear box at the factory, all it did was destroy the bearings
01:56 PM fragalot: I found some of that too
01:56 PM fragalot: I also found that the oil level in the head isn't high enough to reach the top gear
01:58 PM hazzy-lab: I fill mine all they way up! It oozes out the vent on a hot day, but better than than run it dry
01:58 PM miss0r: hehe
01:58 PM miss0r: Install a paddle wheel
01:59 PM fragalot: i've got a vent extension :P
01:59 PM fragalot: from factory the vent was just a piece of tubing going nowhere.. not sure what that was about
01:59 PM miss0r: thats cheating
01:59 PM hazzy-lab: hehe, it probably does churn around enough to get up there, but ...
02:00 PM hazzy-lab: fragalot: hehe, maybe they did that so the oil does not poor out when you tilt the head (like it does on mine ...)
02:01 PM fragalot: wasn't quite long enough for that.. then again I got it 2nd hand so it might have been
02:07 PM fragalot: cradek: depending on the steel they may not ever get glass hard
02:07 PM fragalot: cradek: and also, it's not because he didn't film it that he didn't do it
02:12 PM * SpeedEvil sighs at finding his chainsaw lube pump is dead.
02:26 PM hazzy-lab: hazzy-dev: has never had a chainsaw with a pump that worked
02:27 PM hazzy-lab: I guess that is not true, but the new stihl saws are so stingy with the oil it might as well not work
02:29 PM fragalot: hazzy-lab: still drooling a bit of your rebuild pics :-) did you ever check how square everything was before you started vs after?
02:29 PM JT-Shop: yea the new chainsaws only pump 1/2 as much oil
02:29 PM fragalot: or did you not make any dimensional changes
02:32 PM hazzy-lab: fragalot: I did check before and after, I had to tilt the column back a little bit to get the head trammed, and now it is pretty close in all directions, about .0005 over 6in
02:33 PM fragalot: nice
02:33 PM fragalot: mine had an out of square saddle
02:33 PM fragalot: well over 4 thou per 4"
02:33 PM hazzy-lab: The problem is the column dovetails tend to squeeze together a bit then the head is in the middle of the travel, so the head sags, but it is not much
02:33 PM hazzy-lab: Wow, that is way out!
02:34 PM fragalot: yup
02:34 PM hazzy-lab: I was very pleased with this machine, very usable even as it arrived, just looked like sh*t
02:35 PM fragalot: https://photos.app.goo.gl/ojchujCF1esupgTs5
02:35 PM phaxx: how tight should thrust bearings be?
02:35 PM fragalot: phaxx: snug, not tight
02:35 PM fragalot: all you're doing is removing play
02:35 PM skunkworks: hazzy-lab: finally working on my small cnc mill. All apart - needs a riser and some tlc
02:36 PM phaxx: hm, thanks.
02:56 PM JT-Shop: nice to have a bigger machine to fix your smaller one
02:57 PM lcvette_: hazzy-lab: the column dovetail pinch issue is a painful one for most small bench mills, i know my little G0704 suffers from it terribly
02:57 PM fragalot: took me some looking to find someone willing to help :P
02:57 PM lcvette_: tight at the top and bottom and sags in the middle
02:57 PM JT-Shop: looks like the fixup went well
02:57 PM fragalot: lcvette_: I wonder if a spacer in the head saddle would help?
02:58 PM lcvette_: problem is the ballscrew resides in there and there isn't much room
02:58 PM fragalot: there is room above & below the ballscrew mount
02:58 PM fragalot: granted, you'd have to machine the column for this to work
02:58 PM lcvette_: its a "C" channel with the center open for the ballnut to travel
02:59 PM lcvette_: ive imagined a sliding bearing
02:59 PM lcvette_: but that would require some serious precision on that opening be ground
02:59 PM fragalot: or scraped, but yes
02:59 PM lcvette_: and if you are going that far... may as well just go linears
02:59 PM Wolf__: fix for my small mill was to replace it with a knee mill
02:59 PM fragalot: lol
03:00 PM fragalot: if they made a knee mill that takes the same footprint as my rf45 i'm interested
03:00 PM gloops: bend the middle over a shim
03:00 PM lcvette_: if you go with say a Hiwin RG series pin roller type the issue is gone because the z saddle now helps to fix the problem
03:01 PM lcvette_: not following gloops
03:01 PM gloops: im not either lol, but it was just a thought
03:05 PM hazzy-lab: fragalot: Looks like you are doing a very nice job re-machining those castings!
03:05 PM hazzy-lab: That unobtainium 55deg is leaving a nice finish, guess it has not come off the arbor, yet? :D
03:05 PM fragalot: :P
03:06 PM fragalot: a nice mirror finish for me to scrape the rest of the way
03:09 PM hazzy-lab: lcvette_: I think linear bearings are the only real solution, but the sag is really not enough to effect most parts so its not really worth the effort
03:09 PM fragalot: i've got so much slop in the spindle that I doubt I notice the sag
03:09 PM lcvette_: slop?
03:09 PM fragalot: play
03:09 PM lcvette_: runout?
03:10 PM fragalot: sideways movement
03:10 PM hazzy-lab: Wolf__: same here! I go to the PB for everything that I don't absolutely need CNC for
03:10 PM lcvette_: that can be fixed easy
03:10 PM lcvette_: are you going cnc?
03:10 PM fragalot: lcvette_: listening.
03:10 PM fragalot: no
03:10 PM lcvette_: Y not?
03:10 PM lcvette_: lol
03:11 PM fragalot: because i'm building a proper granite one :P
03:11 PM lcvette_: so its in your quill
03:11 PM fragalot: yeah
03:11 PM lcvette_: ok
03:11 PM lcvette_: well you can take the quill and have it spray welded
03:11 PM lcvette_: than have it ground
03:11 PM fragalot: That is indeed an option.
03:12 PM lcvette_: the other option is bore and sleeve the head casting
03:12 PM hazzy-lab: OR, drill six holes in the quill housing and make little brash plugs to push on the quill and take out the play, I did that and it works great
03:12 PM fragalot: that is indeed another option
03:12 PM hazzy-lab: brass* lol
03:13 PM fragalot: hazzy-lab: really? only in a single ring pattern, or also higher up inside the head?
03:13 PM lcvette_: you appear to have access to machines
03:13 PM fragalot: lcvette_: I do - but first I want to finish the cnc build to get some space back
03:13 PM hazzy-lab: Three at the bottom, three at the top
03:13 PM fragalot: I can work around the sloppy spindle for now
03:13 PM lcvette_: gotcha
03:14 PM Deejay: re
03:15 PM hazzy-lab: wb
03:15 PM Deejay: tnx
03:15 PM Tom_L: lcvette_ do you still have your G0704?
03:16 PM Tom_L: is that the one you swapped spindle motors on?
03:25 PM gloops: Kane again 90 minutes heh heh
04:09 PM Tom_L: finally got the manual for this item: https://tinyurl.com/y9pzs2v2 if anybody cares to comment on it http://tom-itx.no-ip.biz:81/~webpage/cnc/BLDC/Motor&Controller.pdf
04:10 PM lcvette_: Tom_L: yes
04:10 PM lcvette_: still hAVE THE g0704
04:10 PM Tom_L: apparently CN201 disables the buttons and switches to external control
04:11 PM Tom_L: which is PWM
04:12 PM Tom_L: 5sec to get up to speed seems a bit much
04:13 PM lcvette_: Tom_L: did you just buy that bldc?
04:13 PM Tom_L: no
04:13 PM Tom_L: but i got him to send the manual
04:14 PM lcvette_: i cannot stress enough that thing is a giant waste of time and money
04:14 PM lcvette_: buy a servo instead
04:14 PM lcvette_: you would be far better served
04:15 PM Tom_L: at 3x the cost
04:15 PM Tom_L: but it's not out of the question
04:15 PM lcvette_: do you know why that thing is $175
04:15 PM Tom_L: still looking
04:15 PM Tom_L: cause it's made in china and it's cheap
04:15 PM lcvette_: when i bought it was new and they were charging $800
04:15 PM lcvette_: if that tells you anything about them
04:16 PM lcvette_: now they can barely give them away
04:16 PM Tom_L: i bought my first 20M hdd for about that too :D
04:16 PM lcvette_: something is only 3 times the cost if the first thing you buy is the only thing you have to buy
04:16 PM Tom_L: i don't have a 20 ton industrial machine either
04:17 PM lcvette_: it was on a G0704
04:17 PM lcvette_: are you saying your machine is much smaller?
04:17 PM Tom_L: i saw your video
04:17 PM Tom_L: no
04:17 PM lcvette_: that motor and drive is garbage
04:18 PM lcvette_: you will be replacing it inside 6 months if not sooner
04:19 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Chip_Guard2.jpg
04:20 PM Tom_L: i don't have a real good pic of it
04:20 PM gloops: takes mine about 30 seconds to reach top revs
04:20 PM gloops: you cant speed them up too quick really
04:20 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/table_slot1.jpg
04:21 PM Tom_L: i've been looking at a servo as well
04:21 PM Tom_L: would require alot more rewiring
04:22 PM lcvette_: https://www.automationdirect.com/adc/Shopping/Catalog/Motors/AC_Motors_-_General_Purpose_and_Inverter_Duty_(0.25_-_300HP)/AC_Motors,_General_Purpose-z-PE_Rolled_Steel,_IronHorse_0.33-3.0HP/3-Phase_Motors,_56C_(0.33_-_3HP)_TE,_Footed_Rigid/MTR2-P75-3BD36
04:23 PM lcvette_: $99 bucks
04:23 PM Tom_L: that thing's way too big for my mill
04:23 PM lcvette_: grab a $129 sensorless vector vfd off ebay
04:23 PM lcvette_: your golden
04:23 PM lcvette_: thats a little one
04:23 PM lcvette_: 3/4hp
04:24 PM gregcnc: only 22lb
04:26 PM lcvette_: it will live forever
04:27 PM lcvette_: and outperform that crappy chinese bldc setup
04:27 PM Tom_itx: https://store.dmm-tech.com/products/dht-0-75kw-ac-servo-motor
04:28 PM Tom_L: also looking at that one
04:28 PM gloops: https://www.ebay.co.uk/itm/ER25-Spindle-Head-Unit-2HP-Power-Head-3000rpm-5Bearings-CNC-Drilling-Milling/192054805885?
04:28 PM Tom_L: gloops, i've seen those
04:28 PM gloops: any good?
04:28 PM Tom_L: i don't own one
04:29 PM Tom_L: there are several similar ones
04:29 PM tjb1: So would I see any benefit to counting frequency with gatetime on a 75MHz core vs a 16MHz core?
04:30 PM gloops: yeah, seems designed with milling in mind, 5 bearings
04:32 PM piscina: should i make my 12' x 8' shed have 16" on centers?
04:33 PM Tom_L: of course
04:33 PM piscina: what kind of roof should i do? gambrel?
04:33 PM piscina: gable?
04:33 PM Tom_L: and you should make it 24 x 16 instead
04:33 PM piscina: can't go over 100'^2 without a permit
04:34 PM Tom_L: get a permit
04:34 PM Tom_L: huh, it's 400 here i thought
04:34 PM piscina: permits almost always equal higher property tax at the end of the year
04:34 PM gregcnc: 12" thick concrete floor for the 5 axis machine too
04:34 PM piscina: soon as, round here anyways, they find out you've done anything with your house they charge you higher property taxes
04:34 PM gloops: you can make the shed any size you want, nobody ever checks the permits
04:34 PM * piscina gasps
04:35 PM piscina: just because no one watches me shoot smack does that mean it's okay to do?>
04:35 PM Tom_L: gregcnc, don't forget the pit of silicone for a vibration dampener
04:35 PM gregcnc: around here they check google maps and update your tax
04:35 PM gloops: whats going in the shed piscina
04:35 PM piscina: actually it has to go between two trees and a walk-way and fence
04:36 PM Tom_L: gloops growin weed
04:36 PM piscina: seasonal hardware
04:36 PM lcvette_: Tom_L: if there is one thing I have learned, its that you never complain about having too much moto power but you will certainly complain about not having enough
04:36 PM piscina: mower, shovels, rakes, solvents, etc.
04:36 PM gloops: go for duo pitch roof then
04:36 PM gregcnc: doesn't local lumber yard sell kits?
04:36 PM Tom_L: lcvette_, i'm well aware of that senario
04:36 PM lcvette_: and another benefit i found to having alot of weight on the head was it really seemed to calm the vibrations in the cutter down
04:37 PM piscina: wouldn't a kit cost more than building it from scratch?
04:37 PM gloops: i thought you meant a shed for a workshop
04:37 PM gregcnc: no idea, but harder to screw up
04:37 PM fragalot: I disagree
04:38 PM fragalot: mine was a kit and I regret doing that
04:38 PM fragalot: the fit-up of the premade parts is never quite right
04:38 PM Tom_L: i've always scratch built my stuff
04:38 PM fragalot: the roof panels should have been 50mm longer
04:38 PM fragalot: etc
04:38 PM fragalot: if you are able to do so, build it from scratch.
04:38 PM fragalot: I tried to save time by buying a kit but .. meh.
04:38 PM piscina: i think i'm gonna do a gambrel roof cause i want the head-room/extra storage
04:38 PM gloops: not difficult to make a shed with a chop saw
04:38 PM piscina: i think it's gonna be 12 x 8 x 8
04:38 PM fragalot: at least i've got 30yrs warranty on it >.>
04:39 PM gloops: but you know its gonna take a couple of days
04:39 PM piscina: i've done a fair amount of framing with lumber. i have my own spiker. i know how to swing a purse
04:39 PM piscina: :s/purse/hammer/
04:39 PM Tom_L: i did one with a barn like roof for more overhead storage once
04:39 PM piscina: shouldn't take but a morning to frame it out and put a roof on it
04:39 PM piscina: siding and shingles might take a bit more
04:39 PM fragalot: go for it
04:40 PM piscina: trying to convince the old lady, via phone right now, that it needs a 9 x 7 garage door on it too
04:40 PM piscina: on the long side
04:40 PM piscina: she says it'll cost too much
04:40 PM piscina: she wants to see my "Drawing" first
04:40 PM fragalot: yeah but you save money by doing it yourself
04:40 PM piscina: and she wants a "materials list"
04:40 PM Tom_L: give her a drawing
04:40 PM fragalot: and that savings can go towards the door
04:40 PM fragalot: :D
04:41 PM gloops: make it with old pallets
04:41 PM piscina: i have the rails and the hinges for a garage door i just can't find anything decent to make panels with tbh
04:42 PM Tom_L: that shed's barely big enough for a garage door
04:42 PM piscina: i'll have to cut the rails i do have down a bit i figure though. they're for a 16' x 10' garage door initially
04:42 PM Tom_L: what about double doors
04:42 PM piscina: i don't like how double doors flop around after a while
04:42 PM piscina: the hardware never lasts. so much weight
04:43 PM piscina: then the door doesn't close as nice as it should
04:43 PM piscina: and you get debris and shit in the shed, mice
04:43 PM fragalot: just means you need to DIY the hinges too
04:43 PM Tom_L: you'll lose at least 18" of overhead storage too
04:44 PM piscina: which makes the gambrel roof basically pointless to do
04:44 PM piscina: i can't believe this woman
04:44 PM piscina: now i have to draw out a shed
04:44 PM piscina: next she'll make me go to lowes or something and price ou t lumber
04:44 PM fragalot: lol
04:45 PM piscina: then she'll want me to go to roof mart and price out siding and shingles
04:45 PM fragalot: just give her the invoice
04:45 PM fragalot: "about that much"
04:45 PM Tom_itx: http://howtospecialist.com/outdoor/shed/12x8-shed-free-diy-plans/
04:45 PM Tom_L: done deal
04:45 PM Tom_L: she won't know if you got that or not
04:46 PM piscina: she took my credit card and we have a joint account
04:46 PM fragalot: lol
04:46 PM piscina: it's the only reason i have to ask
04:46 PM Tom_L: tricky one there..
04:47 PM piscina: and she'll make my life even more terrible than it already is if i spend "pointless" money
04:47 PM piscina: a shed isn't pointless!
04:47 PM piscina: my wife is a hoarder though
04:47 PM piscina: i swear she has every article of clothing she has ever had in her life in closets around the house
04:48 PM piscina: why do women need so much clothes?
04:48 PM Tom_L: why ask why?
04:48 PM gloops: https://i.pinimg.com/originals/6a/fc/55/6afc55be8207c08b0a3dedbdc71982a8.jpg
04:48 PM piscina: her idea is that she spent good money on things. so those things, in her perspective, are still worth the money she spent on them.
04:49 PM piscina: we have 5 crock pots. and now we only use the insta-pot
04:49 PM piscina: can we get rid of the other crock pots? nope
04:49 PM Tom_L: hide the good one
04:49 PM gloops: sounds like she wears the pants piscina
04:49 PM Tom_L: heh
04:49 PM Tom_L: yup
04:49 PM piscina: on yah. she definitely does
04:50 PM piscina: she also makes over double what i make a year so...
04:50 PM piscina: roll reversal
04:50 PM piscina: i also do the dished and maintain the house
04:50 PM piscina: i call 'em "pink jobs"
04:50 PM Tom_L: price a house keeper and present that to her
04:50 PM piscina: she'll ask me if i'm lazy or something. then ridicule me for a good week.
04:51 PM Tom_L: you may need more than a shed
04:51 PM piscina: ;]
04:51 PM piscina: that's what my old man says
04:51 PM piscina: i just need to clean the garage reasonably
04:51 PM piscina: she has 4 lawn mowers
04:52 PM piscina: i don't think 2 of them will ever work again. i'm not allowed to throw them out though.
04:54 PM fragalot: that's why you need the shed
04:54 PM fragalot: where else would you keep 'm
04:56 PM piscina: she has this spade shovel that isn't a spade anymore
04:56 PM piscina: it's a square
04:57 PM piscina: and 3 wooden ladders that i wouldn't even stand on the first step of
04:57 PM piscina: her parents kept all their toys from when they were children and gave them to her
04:57 PM piscina: it's a generational problem i'm sure
04:58 PM piscina: she wants a drawing? she'll get a drawing!
04:58 PM piscina: sitting at the drafting table now
04:59 PM rmu: you need marriage counselor
05:09 PM piscina: you ever seen the key and peele skit?
05:10 PM piscina: https://www.youtube.com/watch?v=5LGEiIL1__s <-- serious lulz
05:11 PM piscina: darrel, i looked my woman in the eye socks, i said...
05:22 PM Deejay: gn8
06:16 PM ChanServ changed topic of #linuxcnc to: Forum downtime for upgrade starting at 1500UTC | LinuxCNC is a linux-based open-source CNC control. | Latest release: 2.7.14 | http://www.linuxcnc.org
06:38 PM phaxx: nothing quite like fusion360, a local application, prompting you to login to remind you that you don't own shit anymore.
06:41 PM Tom_L: it's been that way all along, they're just enforcing it differently now
06:46 PM phaxx: yep. still jarring. :)
06:47 PM Kevin`: surely you don't rely on fusion 360 for anything that needs to be available in the future?
06:49 PM phaxx: nah, hobbyist level user here.
06:53 PM hazzy-lab: What's really frustrating is when you go out in the field where there is no Internet, spend hours drawing up a part in F360, and then try to save it, it is impossible! Can't even export and save it locally like you normally can. What I ended up doing was holding down the power button to power off my laptop, and then use the "restore unsaved documents" feature in F360
06:53 PM hazzy-lab: That was the first and last time I used F360 for anything other than play
07:07 PM tjb1: Got my UC100 for G540 and they used female db25...
07:18 PM phaxx: hazzy-lab: hah, awful. brave though, to rely on the document restore feature.
07:21 PM hazzy-lab: It was my only hope! I had spent hours trying to save the model
07:37 PM CaptHindsight: I found the marriage drama to be a nice change from the usual in here, but lets not make a habit of either
07:39 PM CaptHindsight: please
07:44 PM enleth: hazzy-lab: uh... what about just suspending the laptop?
07:45 PM enleth: also, please someone remove that forum downtime message from the topic
07:47 PM CaptHindsight: probably best to make that request 7-9 hours earlier than this time of the day
07:48 PM CaptHindsight: seb is probably driving home right now in traffic
07:49 PM CaptHindsight: first archivist, now jym is gone

07:51 PM CaptHindsight: kewl now we are going to get spaceships with lasers
07:56 PM Tom_L: where'd jymmmmmmmmm go?
07:57 PM CaptHindsight: .seen jymmm
07:57 PM theCockerel: Sorry, I haven't seen jymmm around.
07:57 PM CaptHindsight: how many mmmm's did he use?
07:58 PM CaptHindsight: .seen Jymmm
07:58 PM theCockerel: Sorry, I haven't seen Jymmm around.
07:58 PM CaptHindsight: they found a way out and left!
08:21 PM hazzy-lab: enleth: It would just start right back up with F360 running, and not let me save the file. If I tried to close F360, it would give me the option to discard changes or save, but save would not work
08:23 PM hazzy-lab: yeah, wonder what did happen to jymmm
08:24 PM enleth: hazzy-lab: but you could have just kept it running until you had an internet connection. I know, still a workaround, but a more convenient one
08:24 PM enleth: ("running", but suspended)
08:25 PM CaptHindsight: .seen t12
08:25 PM theCockerel: Sorry, I haven't seen t12 around.
08:25 PM hazzy-lab: Oh, I did have an Internet connection when I tried to save it, I knew it would not work with out one so only tried when I go back home
08:26 PM hazzy-lab: But since it was not created when it was connected it would not let me save it
08:26 PM enleth: ah, OK, I get it now
08:26 PM CaptHindsight: .seen MacGalempsy
08:26 PM theCockerel: Sorry, I haven't seen MacGalempsy around.
08:26 PM enleth: hazzy-lab: did you file a bug report?
08:26 PM enleth: they tend to actually fix stuff they get reported
08:27 PM hazzy-lab: I was going to, but there were already sever filed for the same issue with no fixes
08:27 PM hazzy-lab: several*
08:27 PM enleth: ah, *that* is shitty then
08:47 PM Tom_L: .seen theCockerel
08:47 PM theCockerel: Tom_L: I'm right here!
08:48 PM Tom_L: bot hasn't been around long enough
08:52 PM CaptHindsight: few months
08:52 PM CaptHindsight: .seeen anyone
08:52 PM CaptHindsight: .seen anyone
08:52 PM theCockerel: Sorry, I haven't seen anyone around.
08:52 PM CaptHindsight: .seen yourself
08:53 PM theCockerel: Sorry, I haven't seen yourself around.
08:53 PM CaptHindsight: .seen nobody
08:53 PM theCockerel: Sorry, I haven't seen nobody around.
09:03 PM evilren_ is now known as renesis
09:12 PM Tecan: wow the great pyramid was 6.5 million tons roughly
09:29 PM CaptHindsight: probably why they sell those small models of it at the shops, shipping full size copies would be expensive
11:05 PM MrHindsight is now known as CaptHindsight
11:13 PM hazzy-lab: LMAO Capt
11:13 PM * hazzy-lab must be tired
11:37 PM CaptHindsight: it's been one of those days
11:37 PM CaptHindsight: for the past few years
