12:47 AM XXCoder: interesting. https://www.aliexpress.com/item/4000047700719.html pink_vampire
12:52 AM XXCoder: 20w and can engrave metal, and cut wood
12:52 AM XXCoder: 120 for laser only not too bad
12:52 AM XXCoder: i wont build one till I have room for enclosure though. 20w is just scary lol
01:26 AM Loetmichel: XXCoder: 20W? pish! Friend built an 80W co2 lasercutter a while back. with no enclosure at all... was always a bit frightened around it, not only because "protect your remaining eye" but also because: 8kV HURT, even when current limited to a few 100mA ;)
01:27 AM Loetmichel: and yes, i am speaking from experience, accidentally touched the laser tube ends a few times while in operation.
01:34 AM Elmo40: Loetmichel, they arent accidents
01:34 AM Loetmichel: not?
01:34 AM Elmo40: just look at your track record
01:34 AM Elmo40: you are simply a clutz
01:34 AM Loetmichel: just because i am slightly careless dont make them not accidents. it just makes me a clutz :)
01:35 AM Elmo40: 'remaining eye' ?
01:35 AM Elmo40: where did the other one get to?
01:36 AM pink_vampire: Elmo40: https://i.imgur.com/ZGeJWyL.png
01:36 AM Elmo40: i think it is calibrated now
01:38 AM Loetmichel: Elmo40: a joke about the sign in nearly every laser lab: "protect your remaining eye!"
02:01 AM XXCoder: Loetmichel: lol
02:01 AM XXCoder: i listen using my eyes so its slightly more mission-critical not to lose sight :)
02:12 AM selroc: what do you plan for coronavirus? telework for everyone?
02:12 AM Loetmichel: XXCoder: you are deaf IIRC? then i can understand that sentiment ;)
02:12 AM XXCoder: yeppers heh
02:27 AM BitEvil is now known as SpeedEvil
03:05 AM Deejay: moin
04:48 AM Tom_L: morning
05:45 AM jthornton: morning
05:48 AM XXCoder: yo
08:28 AM Loetmichel: *blink* *blink* Note to self: use more than 470R for a 3mm high efficiency led at 12V if it shall just indicate power one... MAAAN thats BRIGHT! :-)
08:29 AM Loetmichel: ... would have never thought that i would use an L200 in a military device to drop some voltage... the things we do because the chip was at hand :-)
09:27 AM rue_mohr: hah, I used like a 50k on the indicator for my headphone amp, and had to put a peice of tape over it
09:27 AM rue_mohr: I'll go back for it one day
10:17 AM Rab: Loetmichel, I'd thought I was well versed in electronics, but I've never heard of the L200. And it looks like a fairly old part. How does it compare to e.g. LM317?
10:24 AM roycroft: whoever said they were looking for a track saw the other day, there's a ts75 on festoolrecon.com right now
10:31 AM * SpeedEvil ponders festoolrepo.com.
10:56 AM JT-Shop2: hmm that link goes to a Finish Delta Sander DTS 400
11:11 AM Rab: I saw the track saw when roycroft posted it, guess somebody snapped it up and isn't talking. ;)
11:13 AM Tom_L: soggy and 44°F
11:14 AM jthornton: same here
11:41 AM roycroft: the good stuff sells in seconds on the recon site
11:42 AM roycroft: a ts75 usually doesn't last long
11:42 AM roycroft: jt-shop2: the festoolrecon.com site is kind of odd
11:42 AM roycroft: they only post one item at a time, quantity one
11:42 AM roycroft: when that item sells they post another one
11:43 AM Loetmichel: Rab: a few gernations older
11:43 AM Loetmichel: but a bit more versatile
12:00 PM JT-Shop: roycroft, I guess that is one way to do it
12:01 PM JT-Shop: what sander do you use?
12:35 PM roycroft: jt-shop: i have several
12:36 PM roycroft: for rough sanding and general use i have a ets-ec 150/5
12:36 PM roycroft: for finish sanding i use an ets 125/2-req
12:37 PM roycroft: for sanding railings/moldings/etc i have an ls-130
12:37 PM roycroft: for hogging out material i use an ras-115
12:37 PM roycroft: for getting into corners and for doing smaller hogging out i use an ro-90
12:38 PM roycroft: and for doing curved work i will often use my 2x72 belt grinder or my 6x80 edge sander
12:38 PM roycroft: for inside curves i have a bobbin/spindle sander
12:48 PM JT-Shop2: the ets 125 is about what I'm looking for
12:53 PM roycroft: jt-shop2: it's not an agressive sander by any means, but it leaves a beautiful finish, and is relatively inexpensive
12:53 PM roycroft: the ets-ec 125 is a bit more powerful, and the motor is brushless, but it has a 3mm orbit, while the ets 125 has a 2mm orbit
12:54 PM roycroft: both have superior dust extraction, of course
12:55 PM roycroft: you really have to use festool abrasives with their sanders to get good extraction, but, while they cost a bit more than other brands, they last a lot longer, and are really less expensive in the long run
12:56 PM roycroft: i used to use those red (diablo?) abrasive discs from home depot, which i found were pretty good
12:56 PM roycroft: the festool abrasives last at least 2x as long as an equivalent diablo
12:57 PM roycroft: iirc i was paying about $30 for 100 125mm/5" diablo discs, where festool are $48 for 100 discs, so a considerable savings, given how much longer they last
12:58 PM Tom_L: i've got 2 devilbis air sanders
12:58 PM Tom_L: 6 & 8"
12:59 PM Tom_L: free 3m discs i got from my bud that designed the punch press to cut them out
12:59 PM Tom_L: test samples
01:00 PM Tom_L: had a bunch of 3m 'diaper' absorbent material i used on the shop floor until i ran out
01:02 PM Tom_L: ok. out to test cut a bunny (coding assignment my kid had)
01:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/xtra/bunny.jpg
01:03 PM roycroft: i like that air sanders are wicked powerful, but there is no concept of dust extraction with them, and they are noisy as hell
01:03 PM roycroft: so i avoid them these days
01:04 PM Tom_L: these are actually pretty quiet
01:04 PM Tom_L: better than the average air sander
01:04 PM roycroft: the ones i've used aren't
01:04 PM roycroft: but i have not used all air sanders everywhere :)
01:04 PM roycroft: the extraction issue remains, though
01:05 PM roycroft: i'll use an air sander outdoors, but never inside a shop
01:05 PM roycroft: i still have some in my body tools cart
01:05 PM JT-Shop2: roycroft: thanks for the info on the two different sanders
01:05 PM roycroft: sure
01:06 PM roycroft: i'm not a festool fanboi by any means, but their sanders are as good as any others on the market
01:06 PM roycroft: so i'm pretty big on them
01:07 PM roycroft: the ras-115 is discontinued for some reason, but it's available at the recon site fairly often for really cheap - like $160
01:07 PM roycroft: if you need to do any aggressive hogging, pick one up when you see it
01:08 PM roycroft: it has no random orbital function - it's strictly rotary, but it just eats up wood
01:08 PM roycroft: put a 40 grit pad on it and the wood almost melts away
01:09 PM JT-Shop2: wow
01:10 PM roycroft: i also like to use it for cleaning up cast iron machine tables and the like, with a vlies (scotchbrite) pad
01:18 PM JT-Shop2: that's a good idea
02:27 PM roycroft: it works brilliantly, jt-shop2
02:27 PM roycroft: don't use a ro sander for any kind of polishing or cleaning up like that - it will do virtually nothing
02:35 PM JT-Shop2: my cabinet glass door frame is perfect :)
02:36 PM unterhaus: roycroft, went fast, now it's one of their stupid sanders again
02:44 PM unterhaus: I guess it wasn't that fast
03:02 PM Rab: Tom_L, I got commissioned to do a bunny by my niece a few years ago (she thought it was an obvious use for a Rabbot). No pics though.
03:05 PM unterhaus: anyone know a reliable source for genuine SR44 batteries?
03:05 PM Tom_L: this was more a gcode assignment for them
03:05 PM Rab: Tom_L, no G02/G03 yet? ;)
03:05 PM Tom_L: not on that one
03:06 PM Rab: Looks good, far better than I would care to do by hand.
03:06 PM Tom_L: last year they took 3rd in the nation at skillsusa for such a competetion
03:07 PM Tom_L: landed him a job at a large cnc shop fresh out of HS
03:07 PM Tom_L: he's just going back to finish his vo'tech classes for more experience
03:08 PM unterhaus: search for SR44 on amazon, get a batch of results for LR44, which is what I'm afraid of
03:08 PM Rab: unterhaus, I buy from Mouser/Digi-Key. They have Seiko and Renata, at least. The ones I get don't seem to last as long as I feel like they used to, though.
03:08 PM Tom_L: i typically use 357 to replace them
03:09 PM unterhaus: 357 also appears to be widely counterfeited, too bad none of the reviewers check the voltage
03:09 PM Tom_L: The 357 and SR44 are equivalent and both are silver oxide batteries. The alkaline version is LR44. According to Energizer (who doesn't make SR44 and claim that the 357 is their equivalent) the 357 has a bit less mAH rating than their EPX76 silver oxide. The voltage curve of the EPX76 is also a bit flatter than the 357.
03:11 PM CaptHindsight: https://www.harborfreight.com/home-outdoor/home/batteries/button-cell-battery-multi-pack-24-pk-63398.html not worth every penny
03:12 PM Tom_L: aparently sony makes the SR44
03:12 PM Tom_L: https://www.walmart.com/ip/Sony-SR44B1A-Watch-Battery-silver-oxide-1-55V-1pk/181001277
03:12 PM Tom_L: is it worth $17?
03:12 PM XXCoder: 17 bucks for one
03:13 PM Rab: And I thought $3.47 was outrageous: https://www.mouser.com/ProductDetail/Seiko-Instruments/SR44W?qs=sGAEpiMZZMve4%2FbfQkoj%252BATxq4Qmw0zmwm060LiBQHo%3D
03:14 PM Tom_L: https://www.amazon.com/Sony-Silver-Mercury-Battery-Batteries/dp/B00ISCTPOY
03:15 PM Tom_L: https://www.ebay.com/b/Sony-SR44-Watch-Batteries/98625/bn_8936403
03:15 PM Tom_L: 20 for $32
03:16 PM unterhaus: the 20 for $32 has got to be counterfeit
03:16 PM Tom_L: or 25 for $37
03:17 PM unterhaus: almost always a lr44
03:17 PM Tom_L: several choices to make there...
03:17 PM unterhaus: you can tell with a voltmeter, after you waste your time buying
03:18 PM Tom_L: no, you can and i'll wait for the results :)
03:19 PM CaptHindsight: does the application really require a SR44?
03:19 PM unterhaus: an LR44 in a caliper is a very annoying thing
03:20 PM CaptHindsight: I just change them all the time
03:20 PM unterhaus: an sr44 doesn't cost that much if you can find them
03:20 PM CaptHindsight: takes seconds then worry about something else
03:22 PM unterhaus: I was hoping someone had found a supplier. Maybe next time I order from mouser
03:23 PM CaptHindsight: just another ruined industry
03:23 PM unterhaus: I blame you
03:23 PM CaptHindsight: also why it's so difficult to find things on amazon
03:24 PM XXCoder: amazon is clones all way down
03:24 PM CaptHindsight: nah, was already ruined, i just don't care any more
03:24 PM unterhaus: I feel like we have gained a lot, but some marginal stuff like this is really annoying
03:25 PM Tom_L: tape a solar pannel to the side of them
03:25 PM CaptHindsight: cheap wins
03:25 PM CaptHindsight: also stupid
03:27 PM unterhaus: ya
03:27 PM unterhaus: If you need an 8mm lead screw you are in luck
03:27 PM unterhaus: but outside the parameters they have chosen, no joy
03:29 PM unterhaus: trying to decide if I should stock up for the coronavirus quarantine
03:50 PM Deejay: gn8
05:31 PM unterhaus: 6mm socket head cap screw head is bigger than 1/4" cap screw. Huh
05:31 PM unterhaus: was about to buy a 1/4" counterbore
05:32 PM Tom_L: or plunge cut an endmill
05:33 PM innkeeper: for a cheap cnc machine i can build or buy to mill out 16ga (0.051" | 1.30 mm) sheets for control panel use. ... probably not bigger then 400mm long by 200 wide ... 1'4" x 6" .. what would be some good ones to look at
05:33 PM innkeeper: sluminum sheets
05:34 PM innkeeper: aluminum
05:34 PM unterhaus: mill is not working
05:35 PM unterhaus: pilot on the 6mm is 5/16", seems like a lot of clearance
05:35 PM gregcnc: button cells from mcmaster cheap
05:36 PM gregcnc: what I've received was Varta
05:36 PM Tom_L: unterhaus, i can't remember what i used on mine but i got them surplus
05:37 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Y_Axis_Plate2.jpg
05:37 PM Tom_L: i _think_ those were 6mm, maybe 5...
05:38 PM unterhaus: I will probably use it again, I feel guilty using a drill bit to counterbore, but I have done it
05:39 PM Tom_L: the ones i had had replaceable centers
05:40 PM unterhaus: I hope you can trust mcmaster not to ship counterfeit batterys
05:41 PM unterhaus: There are sets of counterbores on amazon for a reasonable price, but I don't really want a set
05:43 PM Tom_L: what do you expect to pay?
05:43 PM Tom_L: carbide for $60
05:44 PM Tom_L: https://www.mscdirect.com/product/details/01570019
05:45 PM Tom_L: https://www.kbctools.com/catsearch/44/cap-screw-counterbores
05:45 PM unterhaus: don't need carbide. Mcmaster HSS $30
05:46 PM Tom_L: i wasn't planning to use it past that job so i was ok with a used one
05:47 PM unterhaus: I would be happy with a used one, but I'm not going to work too hard to find one
05:48 PM unterhaus: just ordered the mcmaster one, needed other stuff. And ordered some SR44 like gregcnc said
05:48 PM unterhaus: $2.55, not bad if they are real
05:49 PM gregcnc: https://www.ebay.com/itm/232065571461
05:49 PM gregcnc: too late I guess
05:50 PM unterhaus: I'll have mine on wednesday. shoulda ordered 30 minutes ago, would have been here tomorrow
05:51 PM gregcnc: i hate it when that happens, seems like the cutoff varies slightly
05:52 PM unterhaus: probably wouldn't have gotten to it tomorrow anyway
05:54 PM JT-Shop2: yippie my Woodpeckers nuts showed up today
05:54 PM unterhaus: are they red?
06:13 PM unterhaus: back before amazon, I knew someone that ordered toilet paper from McMaster because it would be there the next day
06:18 PM jthornton: silver nuts
06:21 PM CaptHindsight: are there any CAM tools to automate aligning parts in a mill and generating the tool paths to trim the perimeter of cast parts?
06:22 PM CaptHindsight: it's easy enough to create the models for parts along with fiducials for alignment in a jig
06:23 PM CaptHindsight: but say each cast or printed part is unique and you want CAM to generate a tool path for each unique part
06:24 PM CaptHindsight: to make this easier all the parts are about the same size
06:24 PM CaptHindsight: and the jigs will all be the same
06:25 PM CaptHindsight: another scenario could be trimming the excess plastic from vacuum formed parts
06:26 PM gregcnc: are you using assemblies to do you CAM now?
06:27 PM CaptHindsight: by assemblies do you mean groups of parts or?
06:27 PM gregcnc: is your CAM intergal to CAD?
06:27 PM CaptHindsight: yeah if its NX
06:28 PM CaptHindsight: but was wondering about lower cost CAD CAM apps
06:28 PM gregcnc: you build an assembly to create CAM toolpath, duplicate file sub in new part, and if they are similar enough most of the work is done
06:30 PM gregcnc: looks like the snowstorm fizzled out.
06:30 PM CaptHindsight: for tomorrow?
06:31 PM CaptHindsight: went from 6+ inch prediction down to 1.5 for tomorrow
06:31 PM gregcnc: yeah
06:31 PM CaptHindsight: gregcnc: say you have a bunch of STL files, all different but approximately the same size
06:32 PM CaptHindsight: you cast or 3d print the molds
06:32 PM unterhaus: we're getting rain
06:33 PM CaptHindsight: then you want to CNC trim each part off a tree or vacuum form and then trim the excess sheet from each part
06:33 PM CaptHindsight: and you want to automate all the CAM
06:34 PM CaptHindsight: so you have a list of CAD files (stl, step, etc)
06:34 PM CaptHindsight: you have a stack of parts to be trimmed
06:34 PM gregcnc: starting a vacuum form protoype shop?
06:34 PM CaptHindsight: nope
06:34 PM CaptHindsight: looking for software
06:35 PM CaptHindsight: vs writing it all myself
06:35 PM gregcnc: that sounds very specialized. The process I describe is very common for family parts in most CAM
06:36 PM CaptHindsight: if they can afford to use NX this makes it all easier
06:37 PM CaptHindsight: but if the CAD is generated by 3d scanning and you end up with a step or stl...
06:37 PM gregcnc: right
06:37 PM CaptHindsight: there is not much CAD involved other than grouping or nesting
06:38 PM CaptHindsight: or your CAM can next
06:39 PM gregcnc: I have not idea outside normal CAD CAM
06:40 PM CaptHindsight: what if FreeCAD is your CAD?
06:40 PM gregcnc: sorry idunno
06:41 PM CaptHindsight: and PYCAM is your CAM since it's pretty simple stuff that you are casting or printing
06:41 PM Tom_L: has anybody produced useable gcode from freecad?
06:41 PM CaptHindsight: HAH, are there any 3rd party tools for things like this?
06:44 PM jthornton: got the intake manifold off of Rusty this evening, now to clean up the rat crap and replace the knock sensors wiring harness
06:45 PM CaptHindsight: jthornton: after what you went through I'd probably build some sort of barrier or trap on the manifold
06:45 PM gregcnc: I got lucky and didn't have to replace that starter. turned out the ground strap to the engine had a bad connection.
06:45 PM jthornton: this is the second time and that thought has crossed my mind for sure, rat poison is in several places under the hood
06:46 PM CaptHindsight: jthornton: soy based insulation on the old wiring?
06:46 PM CaptHindsight: gregcnc: yeah, yes for once in while it was an easy fix
06:47 PM gregcnc: cost me a tow, because by the time it wouldn't crank that battery in the car was dead too, so it wouldn't jump start either
06:49 PM _unreal_: Tom_L, there are a few
06:50 PM CaptHindsight: https://youtu.be/ZlCNYLrDCQ0?t=55 say you want to automate trimming on a CNC mill
06:51 PM CaptHindsight: but each part has a slightly different shape and you have the CAD for each file
06:51 PM CaptHindsight: file/part
06:52 PM gregcnc: is each part different forever?
06:52 PM gregcnc: or is there just a 10, 000 part library?
06:52 PM CaptHindsight: forever different
06:53 PM CaptHindsight: but all about the same size and shape
06:54 PM CaptHindsight: you want to trim +/- 100th of an inch but the parts may vary 1/4 inch in any direction, max volume of the parts is fixed say 3 x 3 x 3"
06:56 PM CaptHindsight: MasterCAM starts at what? ~$10K just to start plus you still have to automate this
07:02 PM CaptHindsight: another approach is use the CAD along with a camera, align the part using the camera, trim the parts perimeter
07:04 PM Tom_L: align the trim code with a probe
07:05 PM CaptHindsight: we can add alignment marks to the CAD file so it gets printed or cast
07:06 PM gregcnc: that's a long ballscrew https://chicago.craigslist.org/chc/tls/d/des-plaines-unfinish-project-8-4-cnc/7081589943.html
07:08 PM CaptHindsight: yeah, maybe he didn't know where to find good rack gears
07:10 PM CaptHindsight: only days left to assemble
07:11 PM Rab: CaptHindsight, maybe automated probing would be a better workflow than having to load the correct CAD file for each unique part.
07:11 PM Rab: Somebody asked about something similar, but an innie rather than an outtie: https://forum.linuxcnc.org/40-subroutines-and-ngcgui/27397-tracing-curve-with-probe
07:12 PM CaptHindsight: there already is CAD for each part
07:12 PM CaptHindsight: probing takes time
07:13 PM CaptHindsight: a camera can align in a second
07:14 PM CaptHindsight: solidworks + mastercam might be $15-20K plus whatever to automate
07:16 PM CaptHindsight: in the case of vacuum forming there might be 20 parts done at a time with one sheet of plastic
07:16 PM CaptHindsight: each part is unique
07:17 PM CaptHindsight: then CNC mill to trim each part from the film
07:17 PM CaptHindsight: film/sheet
07:17 PM CaptHindsight: it's rigid
07:18 PM Tom_L: trim die in a press if you're making a bunch
07:19 PM CaptHindsight: Tom_L: each part is slightly different shaped, so you would need a unique die for each
07:19 PM CaptHindsight: think of each part like a snowflake
07:19 PM CaptHindsight: about the same size but all different
07:20 PM Tom_L: just had to bring up snow .....
07:20 PM CaptHindsight: sorry
07:20 PM Tom_L: pretty much over that for the year
07:21 PM CaptHindsight: Rab: yes, i see what he is trying to do, but we have CAD for each part (or oval in that scenario on the forum)
07:21 PM CaptHindsight: we were 50 something this past weekend
07:21 PM CaptHindsight: back down to 5 again at night later this week
07:21 PM CaptHindsight: been that way for the past few weeks
07:22 PM CaptHindsight: ~8 day warm to cold cycle
07:22 PM CaptHindsight: and we had winter in october :(
07:23 PM CaptHindsight: so this is the 5th month of winter already
07:23 PM Tom_L: been a bit crazy this year for sure
07:24 PM Rab: CaptHindsight, do all the parts share a common feature with the same coordinates in CAD? Maybe you could make a locating jig which fits the part the same way as the form.
07:25 PM Rab: IOW the outer dimension varies, but the inner surface which conformed to the form should be more consistent.
07:28 PM Rab: If the CAD parts all have an origin of X0Y0, maybe even a L-shaped peg system which fits under the part. If there's a corner radius you move the pegs out, but still have the X and Y reference for the edges of the part.
07:28 PM CaptHindsight: Rab: yes, what i was thinking
07:29 PM CaptHindsight: Rab: we can even have alignment marks in the base of the part that gets trimmed off
07:30 PM CaptHindsight: Rab: you have list of CAD files and you have a list of matching CAM files for trimming
07:30 PM CaptHindsight: the parts are all aligned with the same origin XYZ
07:32 PM CaptHindsight: are there any CAD CAM utils that automate keeping track of all the files and sending them to the CNC mill for trimming?
07:33 PM CaptHindsight: a team of machinists can do this by hand
07:33 PM CaptHindsight: but this needs to be automated
07:34 PM CaptHindsight: at least the trimming or parts, it parts can still be handled bu humans hands from the vacuum press to CNC mill
07:35 PM CaptHindsight: sorry let me fix that sentence
07:36 PM CaptHindsight: at least the trimming of parts, this should be automated, parts can still be handled by human hands from the vacuum press to CNC mill
07:44 PM CaptHindsight: CAx, MRP and ERP all looks custom and expensive
08:40 PM _unreal_: sigh...
08:40 PM _unreal_: not going to see my parts till wed
08:41 PM _unreal_: I'm minus 2 parts to make my programmer "" with luck"" work
08:44 PM _unreal_: OMG I have little I can do right now
08:44 PM _unreal_: so annoying
08:45 PM _unreal_: I'm trying to figure out how to setup my parts for the contoller
08:45 PM Tom_L: seems to be a theme with you
08:45 PM _unreal_: I have TWO massive caps
08:45 PM _unreal_: I assume it would not be legal to mount them outside of an enclosure
08:45 PM Tom_L: i didn't have massive caps so i went with several smaller ones
08:46 PM Tom_L: probably not
08:46 PM * _unreal_ is no electrician
08:46 PM _unreal_: I got 2x 75vdc 27,000uF caps
08:47 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/psu/caps2.jpg
08:47 PM _unreal_: ? Tom_L are my eyes warped or are a few of the casing on those caps dented?
