12:27 AM XXCoder: must have been a decade since i last logged in
12:34 AM XXCoder: good to hear they "improved" since
12:34 AM veegee: Perfect https://www.youtube.com/watch?v=iP1Im4QILS0
12:34 AM veegee: Just need to crush some charcoal and mix it with the lead dioxide and heat it
12:34 AM XXCoder: trying to make lead?
12:34 AM veegee: reduce the lead dioxide to lead oxide and then to lead
12:34 AM veegee: they have pure activated carbon in their video so it happens really nicely
12:34 AM veegee: but charcoal should do just fine
01:19 AM Deejay: moin
01:37 AM enleth: veegee: any precautions to not get lead poisoning from the fumes?
01:38 AM veegee: enleth 3m organic vapour cartridges with P100 filters on a full face respirator
01:38 AM veegee: also doing it outside
01:39 AM veegee: I'm not worried about that
01:39 AM veegee: the melting temperatures are also really low. Like less than 700ºC
01:40 AM veegee: Need it to be above 600º to make sure that the lead dioxide reduces to lead oxide, then the carbon takes it the rest of the way to pure lead
01:40 AM veegee: XXCoder and yeah cheap if you have 5,000 lbs worth of industrial lead acid batteries
01:40 AM XXCoder: not bad
01:40 AM veegee: you get 50% of it instantly because the negative plates are just lead
01:41 AM veegee: the other 50% are lead dioxide, that's when you need to go through all this silly business to purify it to lead
01:42 AM veegee: I have so many uses for lead as a counterweight
01:42 AM veegee: It's such a useful metal. I can make an enclosure with sheet metal for something, then pour lead into it for stability.
01:42 AM XXCoder: it definitely useful as weight
01:42 AM veegee: Yeah
01:42 AM XXCoder: easy enough to shape or melt
01:43 AM veegee: Like a raspberry pi for example is so light that the cables connected to it dictate how it sits on your desk (or most of the time levitate in the air propped up by cables)
01:43 AM veegee: I hate that
01:44 AM veegee: pour some lead into a sheet metal rectangle with similar base dimensions and you have a safe heavy baseblate for it
01:44 AM veegee: baseplate*
01:45 AM veegee: I don't even bother welding the last face of the sheet metal container. Tape to cover it up is more than good enough. Not going to hurt anyone
01:45 AM veegee: You really have to try to poison yourself with lead these days. Like you have dig it out with a spoon and eat it
01:45 AM XXCoder: all you need is to wash hands when touch it
01:45 AM veegee: or constantly handle the ingots and not wash your hands and then proceed to lick your hands to clean them
01:45 AM XXCoder: then risk is essentally zero
01:45 AM veegee: yeah
01:46 AM XXCoder: just be careful with envormental exposure
01:46 AM veegee: I melted the lead negative plates
01:46 AM veegee: no fumes emitted
01:46 AM veegee: it just turned from solid to liquid with some slag, end of story
01:46 AM veegee: no smell or anything
01:46 AM XXCoder: theres always outgas
01:46 AM XXCoder: tiny amount maybe but theres some'
01:46 AM veegee: makes sense because the negative plates are made from very pure lead-antimony stock
01:48 AM veegee: the AGM batteries are even better, they use pure lead for the negative plates since the glass mat provides the mechanical strength, so you don't need to alloy the lead with antimony
01:48 AM veegee: They make for shittier batteries, but easier for an amateur to recycle
01:48 AM XXCoder: cool :)
01:49 AM veegee: I'm so tempted: https://www.kijiji.ca/v-view-details.html?adId=1552424616
01:49 AM veegee: XXCoder daddy please buy this for me, I'll be a good boy I promise
01:49 AM XXCoder: concerned with "its age shows"
01:50 AM XXCoder: backlash?
01:50 AM XXCoder: or just paint
04:27 AM Tom_L: morning
04:27 AM miss0r: morning
05:40 AM JT-Cave: morning
06:12 AM miss0r: What do you guys use to protect aluminium when clamping a machined surface in a 3-jaw or vice?
06:15 AM miss0r: Usualy I would use some good quality "tool box" cardboard. But when doing some time consuming milling with coolant, they loose their strength and mush up. That is an issue when I want to excert alot of force onto it, and not grap more than 10mm in a vertical 3-jaw with parallel blocks on it
06:16 AM miss0r: I need a new idea
07:08 AM Tom_L: mylar?
07:09 AM Tom_L: brass or ss shimstock
07:12 AM miss0r: I'm thinking brass is hard enough to mark the surface
07:12 AM miss0r: perhaps mylar
07:14 AM JT-Cave: make an aluminum sleeve like a collet
07:16 AM miss0r: yeah, I guess that'll work
07:22 AM miss0r: Running a 100x10mm slitting saw in quite deep in the side of this workpiece.
07:22 AM miss0r: It needs *some* holding force, even though I'm running it slow af
07:32 AM miss0r: https://imgur.com/a/YbUmfNY
07:34 AM gloops: sheet lead?
07:39 AM miss0r: hmm I think that will just squeeze out..
07:39 AM miss0r: I don't have nay sheet lead to try with, though :)
07:39 AM rs[m]: aluminium soft jaws
07:42 AM miss0r: rs[m]: Yeah; which is basically what JT suggested.
07:42 AM miss0r: I guess I should turn a alu shim ring/sleeve
07:44 AM gregcnc: soft jaws
09:51 AM unterhaus_: I have thought of getting a new chuck just so I could use soft jaws
09:53 AM roycroft: do you have a metal lathe, unterhaus_?
09:53 AM unterhaus_: yes
09:54 AM roycroft: you said the other day that you don't have the ability to mill your new bandsaw fence
09:55 AM roycroft: you can chuck an end mill in your lathe and mount the fence on the carriage and mill it that way
09:55 AM roycroft: it might take a little fiddling to fixture it, but it should not be too difficult to do
10:00 AM roycroft: it would even give you an excuse to make a milling fixture for the lathe
10:07 AM gloops: i did a few bits on the lathe with angle plate and compound vice, not ideal but it gets you out of spot
10:14 AM roycroft: exactly
10:14 AM roycroft: and for something simple like what unterhaus_ needs to do it would be pretty easy to set up
10:18 AM unterhaus_: have to think about that
10:25 AM veegee: What the hell is up with this transformer secondary: https://i.ebayimg.com/00/s/NjAwWDgwMA==/z/k5UAAOSwnW1gR9kg/$_59.JPG
10:25 AM veegee: 208/480/600? What?
10:25 AM veegee: Normally they're 600V to 208Y120
10:53 AM roycroft: yay
10:54 AM roycroft: my county is down to less than 20 new cases/day, and the governor is moving us from high risk to moderate risk on friday
10:54 AM roycroft: we were at extreme risk just two weeks ago, so this is a significant drop
10:54 AM roycroft: we were well over 100 new cases/day two weeks ago
12:45 PM miss0r: 'evening
12:46 PM Tom_L: https://twitter.com/RueNahcMohr/status/1368787248389398529?s=20
12:50 PM miss0r: what a mad man! Who leaves the keys in the chucks like that?! :D
12:54 PM Tom_L: miss0r, you get your fixturing problem worked out?
12:55 PM miss0r: tom_L: I've turned a and opened an aluminium sleeve. I have yet to complete the workpeice that is held with cardboard.
12:55 PM miss0r: So, I have not tested it yet
01:10 PM roycroft: i'm sure the keys in the chuck were just staged for the photo, but i know that when i was taking machining classes, if i had ever left the key in a chuck and taken my hand off the key i'd have been dragged out behind the shop and flogged mercilessly by my instructor
01:10 PM gregcnc: with the chuck key
01:10 PM roycroft: probably with a burlap sack full of chuck keys
01:10 PM miss0r: hehe and serves you right too
01:11 PM roycroft: i've never been flogged
01:11 PM miss0r: now you will remember to never let it sit :)
01:11 PM miss0r: well.. the fear of the flogging will make you remember then
01:11 PM roycroft: it's easy to instill fear in people when there's good reason for doing so and that reason is communicated clearly
01:11 PM miss0r: indeed
01:12 PM CaptHindsight: ever have an instructor that used metaphor or irony to convey a lesson vs physical abuse?
01:12 PM miss0r: for frogs sake! I want a 5-axis cnc machining center. Doing operations with slitting saws takes forever :)
01:13 PM miss0r: yeah.. sure. All of them, if they had anything to say. I've never had an abusive teacher
01:13 PM CaptHindsight: for us it was often ridicule
01:14 PM miss0r: well... There was this priest back when we attented mandatory bible class before we could get christened... He smacked me on the top of my head with his personal bible when I could not sit still :)
01:14 PM roycroft: as painful as the flogging would be, i know it would be less painful and less enduring than having a flying chuck key put my eye out
01:14 PM miss0r: indeed
01:15 PM roycroft: yay~!
01:15 PM roycroft: a bite on my edge sander!
01:15 PM roycroft: and just as i was shopping for abrasive belts for the 2x72 that would be more suitable for wood
01:16 PM miss0r: I've watched a few of these CNC crash videos on youtube. For some reason theres a video in one of them, featuring a student holding the chuckkey of a manual lathe. You can see he is realy putting his back into it, getting ready for a big pull. The lathe is put into back gear and turned on. This is when I just skip ahead. I don't know what happened, but I hate to think about it
01:16 PM miss0r: Theres no way that ends well for the young lad-
01:17 PM gregcnc: it's worth watching
01:18 PM gregcnc: not like the stuff you find on liveleak
01:23 PM CaptHindsight: has anyone annealed their CNC glue gun printed parts?
01:24 PM CaptHindsight: wondering how distortion is being controlled in the process
01:24 PM roycroft: and the guy is coming over today
01:24 PM roycroft: i even told him i'm firm on the price and he did not argue
01:25 PM roycroft: so now it's really time to find good 2x72 belts
01:25 PM gregcnc: don't you bury the print in sand or salt?
01:25 PM roycroft: i use ceramic and zirconia alumina belts on it now, but those aren't good for wood
01:25 PM roycroft: well, they may be, but they're overkill for wood
01:26 PM CaptHindsight: https://rigid.ink/blogs/news/how-to-anneal-your-3d-prints-for-strength
01:26 PM roycroft: so wells fargo kept sending me email after email telling me it would be prudent to lock my credit card if i'm not using it
01:26 PM roycroft: so i locked it
01:27 PM roycroft: now they send me email after email reminding me that it's locked and that i should log in and unlock it if i want to use it
01:27 PM CaptHindsight: they just like staying in touch
01:27 PM roycroft: i think their goal is not to protect my account
01:28 PM roycroft: their goal is to find excuses to send spam
01:28 PM CaptHindsight: most people would enjoy the attention
01:28 PM CaptHindsight: in this age of isolation
01:28 PM roycroft: i get plent of that kind of "attention"
01:28 PM roycroft: thank you very much
01:39 PM JT-Shop: crap! I was so focused on making a right and left part I put the blank in the press brake backwards!
01:43 PM JT-Shop: I did make a beautiful 90 degree bend...
01:44 PM miss0r: lol
01:44 PM miss0r: shit happens
01:47 PM XXCoder: JT-Shop: aw :(
01:47 PM XXCoder: miss0r: never do saws in hurco lol but nice cut it looks like
01:48 PM miss0r: XXCoder: I would NEVER ! unless it is ABS plastic or something
01:48 PM miss0r: and then I would only do it with a smaller diameter blade lol
01:48 PM XXCoder: yeah. plus if you pause, it will go up to z home lol
01:48 PM XXCoder: dumb programming
01:48 PM miss0r: Unless you have the model that just drops z a few mm on pause
01:48 PM miss0r: they also make those :D
01:48 PM XXCoder: jeez lol
01:49 PM XXCoder: thats worse, thats *any time* cant pause
01:49 PM miss0r: indeed
01:49 PM miss0r: also, the break on the z-axis is slow after a few years of use. so if you see an error and press the e-stop, you are likely to crash even harder :D
01:50 PM * XXCoder facepalms
01:50 PM miss0r: hehe. yeah. its a hate & love relationship for me. The only.. and I mean ONLY reason I have some love for them, is because I do repairs for a living :D
01:51 PM miss0r: because they are mostly just a waste of good low quality cast iron
01:51 PM XXCoder: securing the future lol
01:52 PM roycroft: i am getting to the point where i really really need a cnc mill, so that project may take precedence over my other shop fixture projects
01:52 PM miss0r: I don't think I've ever come across a hurco operator that actualy liked it
01:52 PM miss0r: roycroft: Little snippet of advice. Avoid hurco - even.. Especially if you are offered one for a good price
01:54 PM roycroft: i have the machine already - i've had it for a decade
01:54 PM roycroft: and i have most of the parts to do the cnc conversion
01:54 PM miss0r: what machine is it?
01:54 PM roycroft: it's a grizzly mill-drill
01:54 PM roycroft: sieg x3 clone
01:54 PM roycroft: g0463 iirc
01:57 PM roycroft: yes
01:57 PM roycroft: that's the model
01:57 PM miss0r: ahh yeah. that one can do some nice milling - if you keep it light
01:57 PM roycroft: https://www.grizzly.com/products/grizzly-6-x-22-3-4-hp-mill-drill/g0463
01:57 PM XXCoder: how light?
01:57 PM miss0r: it depends :)
01:57 PM roycroft: the funny thing is, i've used it for steel 90+% of the time over the years
01:57 PM XXCoder: wood only? heh
01:57 PM miss0r: no no
01:57 PM miss0r: you can do steel if you run it carefully
01:57 PM roycroft: but when i do the conversion, i'll be making lots of jigs out of aluminium
01:57 PM roycroft: yes
01:57 PM XXCoder: not bad really
01:57 PM roycroft: like i can take 0.010" facing cuts
01:57 PM roycroft: with a bridgeport i'd be able to take 0.075" per go with the same tooling
01:57 PM miss0r: you can actualy get'em to do something a bit heavier if you upgrade the spindle bearings
01:57 PM enleth: Quinn of Blondihacks has a very similar mill, AFAIR
01:57 PM miss0r: Theres a fait chance I will get a kick in the groin for this, but the BP is not exactly a powerhouse either
01:57 PM enleth: she's probably pushing it to the limits, but the results are impressive
01:57 PM miss0r: enleth: Yeah. that is the same model
01:57 PM roycroft: but once i do the conversion, the majority of the work will be in aluminium, mostly 1/2"/12mm thick
01:57 PM roycroft: she's fairly meticulous, enleth
01:58 PM roycroft: she's not the most experiened machinist around, but she knows that and she does her homework before approaching a project
01:58 PM miss0r: not a bad thing to be when doing machining
01:58 PM miss0r: indeed
01:58 PM roycroft: i do not watch her videos all that often, but i do enjoy them when i do
01:58 PM miss0r: unlike some other "machinist" on youtube, she does not make me want to facepalm all the time
01:58 PM roycroft: and that she's a small-shop, small-machine hobbyist really helps
01:59 PM roycroft: i like watching folks like abom
01:59 PM roycroft: but he has real machines and does big work
01:59 PM miss0r: yeah
01:59 PM enleth: miss0r: there are actually rigid ram CNC bridgeports that can do a bit more than the regular models, the iron is beefed up in more places than just the ram
01:59 PM roycroft: it's enjoyable to watch him, but that's not the kind of stuff i do or can do or want to do
01:59 PM enleth: they're still not a VMC by a long shot
01:59 PM roycroft: blodihacks is scaled down to my level :)
01:59 PM miss0r: enleth: Yeah. my mistake here was just assuming that when people say bridgeport they are talking about the "original" tool room mill
02:00 PM enleth: most probably do, and probably never heard of the CNC iron adaptations
02:00 PM roycroft: i usually say "bridgeport class", not "bridgeport"
02:00 PM roycroft: and when i say that i mean a medium-size job shop manual milling machine
02:01 PM miss0r: but that is not doing justice to that size class of, say, deckels
02:01 PM miss0r: which are ridiculously rigid compared to the BP
02:01 PM enleth: deckels, shaublins, etc. are a class of their own, where the overall size and mass is extremely deceptive
02:01 PM roycroft: well just as ther are production lathes vs. toolroom lathes of the same physical size class, so it is with milling machines
02:02 PM miss0r: enleth: Can't argue with that :)
02:07 PM enleth: but they were actually *engineered*, not just slapped together until it "eh, looks good enough"
02:07 PM miss0r: enleth: I was ->| |<- this close to get my hands on a mint deckel FP1... I missed it :-(
02:07 PM roycroft: i don't need high precision with my mill, fortunately
02:07 PM miss0r: roycroft: Eh?
02:07 PM miss0r: what is the point then?
02:07 PM roycroft: i'll primarily be using it to make woodworking jigs once i do the conversion
02:07 PM gloops: sturdy cnc router?
02:07 PM enleth: BTW, if anyone's looking for one of those CNC bridgeports, specifically a model that is *excellent* for a linuxcnc conversion and pretty hard to find, there's a guy in southeast US who has at least one, among a whole warehouse chock full of other machine tools
02:07 PM roycroft: by "high precision" i'm taking about holding 0.0001"/0.002mm
02:07 PM enleth: ABOM did a walkaround of that warehouse something like two years ago and I noticed one Series 1 MDI, identical to mine, in a sweeping shot
02:07 PM roycroft: if i can hold 0.002"/0.05mm i'd be happy
02:07 PM enleth: funny thing is, the MDI model ("manual data input"), which originally can only do one axis at a time under its own power, having a single servo drive and a non-interpolating control, is a better conversion platform than the actual CNC models with simultaneous 3-axis capability
02:07 PM roycroft: which is better than an off-the-shelf tormach
02:07 PM roycroft: i'm interested, btw, in that comment about upgrading the spndle bearings on my machine
02:07 PM miss0r: roycroft: I don't know much about tormach, but if I bought a any cnc mill (not counding the fleabay models) I would be realy crossed if I could not hold 0.015mm tolerances
02:08 PM roycroft: i'll do the conversion as well as i can
02:08 PM roycroft: and hopefully will get it tighter than that
02:09 PM roycroft: but if that's where i land i won't sweat about it
02:09 PM roycroft: that would do what i need to do, for now at least
02:09 PM roycroft: i'm not a good machinist
02:10 PM roycroft: i would not even call myself a machinist at all
02:10 PM roycroft: i've taken machining classes, and i make parts
02:10 PM roycroft: i'm thoughtful and careful
02:10 PM enleth: most of us here are screwaroundists, not machinists
02:10 PM roycroft: but by no means expert in training or developed skills
02:10 PM roycroft: so i try to set realistic expectations for myself
02:11 PM enleth: doesn't mean you can't go full goetteswinter
02:11 PM roycroft: i hope i'm a little more than a screwaroundist
02:11 PM roycroft: well i have limited time
02:11 PM miss0r: shit.. I'm no machinist either. I'm an electrician
02:11 PM roycroft: and i have particular parts i need to make to particular specifications
02:12 PM miss0r: At some point I just decided to start a machine shop and drive around and repair other peoples machines. so Now I am a repairman I guess. hardly a machinist :)
02:12 PM roycroft: so my aim is to spend the least amount of time necessary to upgrade the machine to be able to make those parts to those specifications
02:12 PM miss0r: then the spindle is not where you want to start.
02:12 PM miss0r: Unless you find that the rest of your machine has reached a state where the spindle is the bottleneck
02:13 PM enleth: most important is probably to somehow find good enough affordable ballscrews
02:13 PM JT-Shop: here goes another shot at making a left and right part in the press brake
02:13 PM roycroft: i have the ballscrews
02:13 PM miss0r: fingers crossed, JT
02:14 PM roycroft: and the stepper motors, and the drives, and the mesa boards i need, and the linuxcnc machine
02:14 PM roycroft: and power supplies, and a bunch of other stuff
02:14 PM enleth: you look all set then
02:14 PM roycroft: i still need some connectors, cables, and miscellaneous bits
02:14 PM roycroft: but i have proably 90+% of what i need to do the conversion
02:15 PM roycroft: other than the metal to make all the motor mounts, etc.
02:15 PM miss0r: Untill you actualy start to build it, then you realize you only have around 40% :D
02:15 PM enleth: the worst part is when you realize you need to mill off a bunch of iron where the taller ball nuts attach or whatever and you don't have a second mill to do it with
02:15 PM roycroft: if i'm honest, the main thing that has been holding me back all these years is this:
02:15 PM roycroft: i only have one milling machine
02:16 PM enleth: this exactly.
02:16 PM roycroft: i need the milling machine to make the parts to rebuild the milling machine
02:16 PM roycroft: so i anticipate several rounds of disassbling parts of the machine, fitting the new parts to it, and reassembling it
02:16 PM enleth: roycroft: parts you *make*, you can do beforehand or reassemble the mill to make them after measuring, but the worst is when you need to modify the machine's iron
02:17 PM enleth: cue jury rigging a lathe for milling
02:17 PM roycroft: i don't anticipate much if any of that, other than drilling/tapping for screws
02:18 PM roycroft: i want to install a one-shot lubrication system, but to do that i would need to do significant machining on the iron
02:18 PM enleth: relative height of the ball nut attachment points and the screw bearing holes can be a problem
02:18 PM roycroft: so, at least initially, a one-shot system is not going to happen
02:18 PM enleth: they're probably going to be different than for the existing ACME nuts
02:18 PM roycroft: yes, i anticipate that will be an issue
02:18 PM enleth: if you're lucky, you'll be shimming it
02:19 PM roycroft: there is also a longer table available for my machine
02:19 PM roycroft: i need to decide soon if i want to invest in that or not
02:19 PM roycroft: that would require buying the longer table and also getting a longer ball screw for the x axis
02:20 PM roycroft: i run out of length occasionally now, and the jigs i make for woodworking will be larger than most of the parts i currently make
02:20 PM roycroft: so i'd probably run into that limitation more frequently
02:20 PM enleth: if you do that, you'll probably have an easier time doing the conversion, being able to work on the new table using the old table
02:20 PM miss0r: you know, you could consider just finding an old deckel maho 400 or something. They are quite usable with their philips 432 controller - should you need something a little more beefy
02:21 PM roycroft: on the other hand, if i install a good, repeatable fixture plate, it should be easier to remount parts to work on the other end than with with my current setup
02:21 PM enleth: or look at that MDI Bridgeport if you're up for a 1600kg machine
02:21 PM roycroft: the real problem i have is that i don't have room for a bigger machine
02:21 PM roycroft: and i'm not willing to do what it takes to make more room at the moment
02:22 PM roycroft: if the woodworking busines takes off, and i do that stuff full-time, then it might be time to look at expanding the shop
02:22 PM roycroft: and at that point, buying a bridgeport class mill and converting it might be in the cards
02:22 PM roycroft: i would already have the smaller mill to make parts for the bigger mill conversion project, so that would be easier to deal with
02:23 PM JT-Shop: on to the next part...
02:23 PM roycroft: at least that's my thinking
02:23 PM roycroft: right or wrong
02:23 PM enleth: if that's the case, really do look for a factory CNC bridgeport
02:23 PM enleth: they're *so* much better for conversions
02:23 PM JT-Shop: I think I have a singulator figured out in my head for the magazine...
02:23 PM roycroft: and i just ordered some abrasive belts for wood
02:24 PM enleth: the problem with converting a normal BP is the X motor location, the dumb thing needs to be at the end of the table and stick out half a mile to the side
02:24 PM roycroft: the local makerspace has a bridgeport that was factory cnc
02:24 PM roycroft: it uses some really weird toolholders though
02:24 PM enleth: CNC iron mounts the X motor off the saddle, with a rotating nut
02:24 PM roycroft: and there are only two toolholders at the makerspace
02:24 PM enleth: roycroft: Erickson QuickChange?
02:25 PM roycroft: i forget what they are - it's been a couple years
02:25 PM roycroft: not that though
02:25 PM enleth: KwikSwitch was also used in some models
02:25 PM roycroft: anyway, i looked into buying some, but they were really pricey and hard to find
02:25 PM enleth: Erickson QC holders are still available new and they're not expensive if you know where to look, KwikSwitch is a completely dead system
02:25 PM roycroft: kwik-switch sounds familiar
02:26 PM roycroft: they might be those
02:26 PM enleth: OTOH, spindles are interchangeable between the two
02:26 PM enleth: if I had a KwikSwitch machine, I'd be looking for an Erickson spindle to swap in
02:26 PM roycroft: yes, but i can't do that at the makerspace
02:26 PM roycroft: i gues what i'm getting at is that they have the mill, but i never used it due to the toolholder issue
02:27 PM roycroft: and now there's a pandemic, and the makerspace has been closed for a year
02:27 PM roycroft: so it's moot anyway
02:27 PM enleth: (rigid ram BP spindles are longer than the regular ones because the Varispeed assembly is on a riser to allow the Z ballscrew to telescope around the bullgear housing, but they interchange within the type)
02:27 PM roycroft: yeah, i just found a kwikswitch holder on ebay, and it looks like what i remember
02:28 PM roycroft: and speaking of toolholders
02:28 PM enleth: they were shit out of luck when they got it instead of QC, then
02:29 PM roycroft: the other thing that's been holding me back from doing the conversion is that it makes sense to me to use the tormach toolholder system on my machine
02:29 PM roycroft: it is a small machine with an r8 spindle
02:29 PM roycroft: tormach seems to scale to that pretty well
02:29 PM roycroft: but pricing things out, i could easily spend $1k on the tormach system just to get enough pieces to get started sanely
02:29 PM enleth: no experience with either of those here, can't comment
02:29 PM roycroft: that stuff adds up very quickly
02:30 PM enleth: all I've ever used are ISO and ISO-derived spindle machines
02:30 PM roycroft: i don't want to have to touch off and index every time i make a tooling change
02:30 PM roycroft: and that means having a bunch of toolholders
02:31 PM roycroft: i'm not sure what to do about drills, though
02:31 PM roycroft: i really can't afford to buy a whole lot of drill chucks or dedicated collets/collet holders
02:32 PM roycroft: this is the "i have no experience at all with cnc milling" part that makes me really uncertain about what to expect
02:33 PM roycroft: so maybe i won't need to spend $1k on toolholders at the beginning
02:34 PM roycroft: but i anticipate that if i spend $200 to "just get started" i'll likely get frustrated at having to swap out and reindex tooling all the time, and end up spending that other $800 in short order
02:46 PM enleth: I wonder if this little bandsaw is going to handle this: https://i.imgur.com/YdjrscY.jpg
02:46 PM enleth: so far it's cutting
02:46 PM enleth: 115mm of solid steel
02:48 PM XXCoder: no dripper?
02:49 PM enleth: doesn't have one
02:49 PM enleth: I'm squirting in oil from time to time
02:50 PM XXCoder: ok
02:52 PM enleth: sounds good, isn't stalling or chattering
02:53 PM roycroft: it should handle it just fine as long as you don't cut too fast
02:53 PM enleth: 120mm, actually
02:53 PM XXCoder: yeah
02:53 PM XXCoder: just was surpised because most video or picture i usually see dripper
02:53 PM enleth: belt is set to the lowest speed, whatever that is
02:53 PM gloops: yeah smaller pulley is an idea for steel cutting
02:54 PM enleth: the new base we made actually has a drip tray but we havent gotten around to installing a pump
02:54 PM roycroft: it's the downfeed rate that is most important
02:54 PM enleth: downfeed valve is just barely cracked open
02:55 PM roycroft: i don't know what that means on your particular machine, but it sounds better than having it fully open
02:55 PM gloops: that bandsaw will eat that
02:56 PM enleth: it's a really shit bandsaw that loves throwing blades, so I'm actually surprised it's going well
02:56 PM roycroft: i have a 7x12/180x300 1hp bandsaw, and i made some slices of 4"/100mm stainless steel round bar with it once
02:58 PM roycroft: those little bandsaws are slow, but they can handle a lot and they're really quite, which is what i like the best about them
02:59 PM roycroft: i'd rather start a cut with a nice, quite machine, walk across the room and do other stuff while it's cutting than use a big, noisy abrasive cutoff saw that spews abrasive and metal dust all over the place
03:25 PM miss0r: Thats it for tonight. I now have it setup for the first of two drilling operations from the back. https://imgur.com/a/JUVIf5C
03:25 PM XXCoder: looks very nicely done
03:25 PM miss0r: the inside surface of the large slotting saw cut looks crummy, but it is absolutly smooth to the touch, so I believe it will clean up nicely in the water polishing, and be completely hidden once it has a black oxide finish
03:25 PM miss0r: thanks
03:26 PM XXCoder: yeah its funny how patterns make it look like bad curs
03:27 PM miss0r: well. that slotting saw setup has all ods against it :D
03:27 PM miss0r: wallered out and crooked.
03:27 PM miss0r: I've ordered a new one, but it has not gotten here yet
03:28 PM XXCoder: yeah? wouldnt crooked cause V cuts rather than nice and even flat surface?
03:28 PM Tom_L: miss0r, what's it for?
03:29 PM miss0r: XXCoder: well.. I had to run it slow, like you would not believe how slow, and then magically it ended up touching all the surface :)
03:29 PM XXCoder: nice
03:30 PM miss0r: Tom_L: Its a spin-on oil filter console convertion for a series IIA land rover. Its going to be shipped to australia monday.
03:30 PM miss0r: My very own design
03:30 PM Tom_L: that takes about 4 weeks
03:30 PM Tom_L: under normal circumstances
03:30 PM miss0r: the shipping?
03:31 PM Tom_L: uh huh
03:31 PM miss0r: well. I don't think it takes that long from europe
03:31 PM miss0r: But I realy have no idea. :)
03:31 PM Tom_L: ahh, maybe not from there
03:31 PM Tom_L: i forgot where you were
03:31 PM miss0r: I forget I am here too, sometimes :)
03:32 PM Tom_L: is that a rotary head it's in?
03:32 PM Tom_L: mine doesn't have enough clearance to use it on end like that
03:32 PM miss0r: Mine barely does
03:32 PM miss0r: :)
03:33 PM miss0r: Well, I couldn't fit a drill chuck and a drill on top of this. I will do helical boring with an endmill, theres just enough space for that
03:34 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Rotary2.jpg
03:35 PM miss0r: same exact model I would think
03:35 PM miss0r: Its a pretty nice model
03:35 PM Tom_L: don't use it alot but it's handy to have
03:35 PM miss0r: well, for this setup where I have to grap a round part and drill at a 55 degree angle it works a charm
03:36 PM Tom_L: you should go buy a 5 axis for that
03:36 PM Tom_L: :)
03:37 PM miss0r: Yeah I know :) I realy do want one, you know :D
03:37 PM miss0r: but they are pretty expensive, if I want the same quality in a 5-axis, that I have in this deckel maho here
03:37 PM Tom_L: i'm a bit jealous of my kid, he runs a zimmerman 5 axis at his work
03:37 PM Tom_L: huge parts
03:39 PM miss0r: I can see the charm in that :)
03:45 PM Tom_L: i maybe could take the chuck off and use a plate and get a little done on it
03:46 PM miss0r: Hmm. I guess you could do that.
03:46 PM miss0r: I might even do that
04:03 PM gloops: you lot with all the decent mills and lathes could make a viable 5 axis surely
04:07 PM roycroft: do any of you use openscad?
04:07 PM roycroft: i'm not sure that's even that important
04:07 PM roycroft: here's the situation:
04:07 PM roycroft: i need to design some jigs for steam bending wooden parts
04:08 PM roycroft: the parts will have some springback, which will be a consistent amount for a given type of part
04:08 PM roycroft: so i need to design the parts in some cad application at actual dimensions
04:08 PM roycroft: and then "squeeze" the x axis by a set percentage before milling the jigs
04:08 PM roycroft: i think openscad should be able to do that without much difficulty
04:09 PM roycroft: but is that also something i can do either by editing the gcode, or perhaps with a configuration option in linuxcnc?
04:10 PM roycroft: i can do it easily in autocad
04:10 PM roycroft: but i've no way of generating gcode from autocad
04:11 PM roycroft: it would actually be pretty neat to be able to do it as a linuxcnc configuration
04:12 PM roycroft: so i would never have to concern myself with it while drawing the parts in cad
04:12 PM roycroft: just tell linuxcnc "reduce all x axis movements by 11.5%"
04:16 PM gloops: scale 1 axis independently..freecad should do that, and make gcode
04:16 PM gloops: never used openscad
04:16 PM roycroft: freecad still irritates me
04:16 PM roycroft: i want it not to, but it insists
04:17 PM gloops: lol, it hasnt irritated me for a few years, since thats the last time i used it
04:17 PM XXCoder: .13-.15 sucked
04:17 PM gloops: people seem to be using it more now though, new release out not long ago
04:17 PM XXCoder: .19 is pretty good
04:17 PM roycroft: however, the more i think about it, the more i'd prefer it to be in a linuxcnc profile, so that i never have to concern myself with scaling while i'm drawing
04:18 PM roycroft: the main problem i have is that i try to use it on both macos and linux
04:18 PM roycroft: and it behaves quite differently on each platform
04:18 PM gloops: what was that simple app Ichs used to use with linuxcnc, cant remember the name now
04:18 PM roycroft: and, while it was developed on linux, i have a very difficult time getting it to run on linux reliably
04:19 PM roycroft: 0.18 seems to run ok on linux, but 0.19 is a nightmare
04:19 PM roycroft: and on macos, 0.18 won't run at all - it crashes constantly, so i have to run 0.19
04:19 PM roycroft: and i haven't even tried 0.19 since i recently upgraded to catalina
04:19 PM XXCoder: :(
04:20 PM roycroft: so i have no idea if it even runs on my macs any more
04:20 PM * roycroft quickly checks, now that he's thinking about it
04:20 PM gloops: librecam - is there such a thing
04:20 PM XXCoder: its why it wont be 1.0 product for qyute a while
04:20 PM XXCoder: freecad has cam but its not great
04:21 PM gloops: nah not librecam, cant remember but Ichs used an app like a plugin with linuxcnc, think his videos are gone again now
04:22 PM XXCoder: yeah he was working on previews for freecad cam
04:22 PM * JT-Shop has to be careful to design parts he can actually make lol
04:22 PM roycroft: well, it loads at least, and does not crash right away
04:22 PM roycroft: but here's the thing
04:22 PM roycroft: let's say i want to steam bend some parts out of ash, basswood, and madrone
04:22 PM roycroft: just for examples
04:23 PM roycroft: and i determine that ash will spring back about 12%, basswood 11.5%,and madrone 9%
04:23 PM roycroft: just made up numbers - no correlation to reality
04:23 PM roycroft: if i had a linuxcnc profile for making bending jigs, i should be able to set a variable to the amount of axial shrink i want
04:24 PM roycroft: and run the same gcode for all three jigs
04:24 PM roycroft: if i had to do it in cad i'd have to generate three different gcode files
04:24 PM gloops: well there was an attempt at librecam https://github.com/LibreCAM
04:24 PM roycroft: and if i mod the jig design, i have to mod all three
04:24 PM roycroft: so doing it in linuxcnc would be the best thing
04:24 PM XXCoder: you should be able to, using spreadsheet
04:24 PM roycroft: and i'm 99% sure i could do it there without much difficulty
04:25 PM roycroft: i should have thought it through more before mentioning it
04:25 PM roycroft: because now i really don't want to do it in cad at all
04:25 PM roycroft: or even with the cam software
04:25 PM XXCoder: freecad has spreadsheet
04:26 PM CaptHindsight: let that be a lessen to yah!
04:26 PM roycroft: i'll experiment - i can do it with linuxcnc in demo mode
04:27 PM XXCoder: demo mode?
04:27 PM roycroft: capthingsight: i've been told all my life to think before i speak
04:27 PM roycroft: and i try to heed that advice
04:27 PM roycroft: but i still open my mouth too often
04:27 PM roycroft: whatever they call the non-machine, non-realtime mode
04:28 PM JT-Shop: sim
04:29 PM roycroft: yeah
04:29 PM roycroft: that's the word i was looking for
04:29 PM roycroft: simulator mode
04:29 PM roycroft: am i correct that doing what i want to do should be fairly straightforward?
04:30 PM roycroft: i know that there are movement calibration variables - there has to be for any cnc controller
04:31 PM XXCoder: sim mode ah yes yeah I like that mode too to test styuff on my pc
04:31 PM roycroft: this is something that anyone who does foundry work would deal with, except not on a per-axis basis
04:32 PM roycroft: if you're making casting dies you add a shrink percentage
04:33 PM gloops: well, technically spring isnt the same as scaling one axis independently is it?
04:33 PM gloops: its a horrendously unfathomable scaling of the curve
04:33 PM roycroft: it would be close enough for my application
04:33 PM JT-Shop: roycroft, is the bending jig just one arc?
04:33 PM gloops: yeah i thought that too
04:33 PM roycroft: no, it is multiple arcs
04:33 PM roycroft: the initial ones will be almost sinusoidal
04:34 PM roycroft: i'm thinking the "receiving" side will be one solid piece
04:34 PM roycroft: and the "pushing" sides will be a number of identical single arc pieces
04:35 PM Tom_L: how does scaling affect springback?
04:35 PM JT-Shop: just wondering out loud if you could do that with the tool diameter, for a bigger profile "say" the tool is bigger than it really is
04:35 PM roycroft: so when it comes time to do the bending, i would do the center arc first
04:35 PM roycroft: and then work my way out to the edges
04:35 PM gregcnc: I would design the forms as required in CAD.
04:36 PM roycroft: tom_l: the springback would tend to straighten the wood strip out, so it would mostly elongate along the x axis
04:36 PM Tom_L: when we made hydroblocks we'd use ~2-3 degree undercut so when the bladder smashed the sheet it could spring back where it was supposed to be
04:36 PM roycroft: as i said, different woods will have different amounts of springback
04:36 PM roycroft: so being able to adjust the axial movement in linuxcnc would be the most flexible
04:36 PM gloops: how about an adustable jig?
04:37 PM roycroft: the jig will have to conform pretty closely on both sides
04:37 PM roycroft: i don't see how i could make it adjustable
04:37 PM gloops: they use them for making arcs in UPVC profiles
04:37 PM gregcnc: why screw with some complicated math for gcode when you can just draw what you need?
04:38 PM roycroft: because i'd have to redraw it for every type of wood i would use
04:38 PM gregcnc: once
04:38 PM roycroft: yes
04:38 PM roycroft: and i've not done this particular type of bending before
04:38 PM Tom_L: using alot of cutter comp can get you into trouble on arcs
04:39 PM roycroft: so perhaps just compensating on one axis won't work out
04:39 PM roycroft: i think it will be good enough, but i really don't know for sure
04:39 PM gregcnc: the trouble I see is that first you have to model your situation mathematically and come up with formula to do what you want
04:39 PM roycroft: i may have to adjust both x and y to get it to work the way i want, in which case it may be easier to just draw it for each specific jig
04:39 PM Tom_L: might require a visual for good advise
04:40 PM Tom_L: you can draw one then scale the drawing whatever percent you need
04:40 PM roycroft: well i have to do the cnc conversion on my machine before i can even try this out, so i am getting ahead of myself here :)
04:40 PM Tom_L: any decent cad can do that
04:41 PM roycroft: when i started thinking about moving the cnc conversion up on the priority list all the stuff i want to do with it started coming back to me
04:41 PM roycroft: and i'm getting a little distracted thinking about how to accomplish them
04:41 PM gregcnc: scaling is one thing, trying to correct for the spring over the profile of the part is something much tougher
04:41 PM Tom_L: agreed
04:42 PM roycroft: yes, i agree there
04:42 PM roycroft: but again, this is wood, and it does not have to be perfect
04:42 PM roycroft: if it is close and looks good that's what matters
04:42 PM Tom_L: are there numbers for wood for that?
04:42 PM roycroft: no
04:42 PM roycroft: because every species behaves differently
04:42 PM gregcnc: any preffered sonic cleaner solution for aluminum? I think i have to buy a real one
04:42 PM roycroft: and not only that, the method of drying the wood affects the amount of springback
04:43 PM roycroft: air dried vs. kiln-dried can differ significantly
04:43 PM gregcnc: so how much precision does this require?
04:43 PM roycroft: i've used simple green, but dilute it or it will pit the aluminium over time
04:43 PM roycroft: i can't quantify that exactly, gregcnc
04:43 PM Tom_L: gregcnc, i used to have ammonia solution but sometimes just use mild dish soap
04:43 PM roycroft: i'll just say it has to be visually appealing, i.e. close to what is envisioned
04:43 PM Tom_L: not specific to aluminum
04:44 PM gregcnc: and will you have to put it in your CMM room for a couple weeks to acclimate to the inspection humidity and temperature?
04:44 PM roycroft: there are no mechanical tolerances per se
04:44 PM * roycroft uses simple green to clean most things
04:44 PM gregcnc: so does the spring matter, or even the difference between wods?
04:45 PM roycroft: it matters if it looks too "flat"
04:45 PM roycroft: functunally it does not matter at all
04:45 PM Tom_L: gregcnc, anything specific you're trying to remove from the aluminum?
04:45 PM gregcnc: soluble oil
04:46 PM Tom_L: i used one to clean my rc engines
04:46 PM roycroft: i would use simple green diluted about 15:1
04:46 PM gregcnc: I'm tired of cleaning parts by hand
04:46 PM Tom_L: yeah
04:46 PM roycroft: maybe even 25:1 or 30:1 for soluble oil
04:46 PM Tom_L: doesn't take that long with a cleaner
04:46 PM roycroft: i bought a "big" ultrasonic cleaner a few years ago - it's 20l
04:47 PM roycroft: my old one is 1/2l, and i used it all the time
04:47 PM roycroft: the 20l one is awesome
04:47 PM XXCoder: i like simple green
04:47 PM roycroft: be sure to get a heated one if you don't have one already
04:47 PM XXCoder: very effective cleaner
04:48 PM gregcnc: heater died in the one I have
04:48 PM roycroft: diluted simple green + 60 degrees will clean just about anything
04:48 PM XXCoder: roy i have small ultrasonic, and its great on really deep clean
04:48 PM XXCoder: I use it to clean my watch band for one, and glasses sometimes
04:48 PM roycroft: iirc the 20l one was only about $200
04:48 PM roycroft: which is cheap for what it is
04:49 PM roycroft: i had my 1/2l one for probably 10 years before i got the bigger one
04:49 PM roycroft: i still use them both all the time
04:50 PM roycroft: if i'm only machining a part or two and i forget to heat up the ultrasonic cleaner i'll clean the parts with acetone in a sure shot can
04:50 PM roycroft: but i really prefer to use the ultrasonic cleaner
04:51 PM Tom_itx: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/ultrasonic2.jpg
04:51 PM Tom_L: probably 20+ yrs old
04:51 PM roycroft: https://www.ebay.com/itm//193792095345
04:51 PM roycroft: mine is simlar to that
04:51 PM XXCoder: nice
04:52 PM roycroft: setting it is kind of odd
04:52 PM roycroft: if i turn it on and start setting the temperature up, it will go up to 60 and then stop
04:52 PM roycroft: i can't set it any higher
04:52 PM roycroft: but if i use the down arrow, which i usually do because it's faster, it goes down to zero, then goes to +69
04:53 PM XXCoder: i managed to get $100 machine for just $33
04:53 PM roycroft: and i can continue to set it down by 1 degree at a time, but once i hit 60 i can't go up any more
04:53 PM XXCoder: and its good one, not cheap plastic crap
04:53 PM roycroft: it's an odd logic error
04:53 PM roycroft: both of mine are stainless steel
04:53 PM XXCoder: mine is probably stainless steel
04:54 PM Tom_L: i thought they all were
04:54 PM roycroft: but in the small one i almost always put the parts in a jar, and just put plain water in the tank
04:54 PM XXCoder: nah theres plastic ones for glasses and such
04:54 PM roycroft: some have plastic tanks
04:54 PM roycroft: but we probably shouldn't talk about those :)
04:54 PM XXCoder: or basically entirely plastic besides electrics heh
04:54 PM Tom_L: if i use different solvents in it, i put it in a jar in water
04:54 PM roycroft: i'm not sure how effective the plastic ones are even
04:55 PM roycroft: i should think that the plastic would dampen the ultrasonic vibration somewhat
04:55 PM roycroft: that's why i use a jar in my little one
04:55 PM Tom_L: not something i would get
04:55 PM roycroft: i like to use different solvents at times
04:55 PM roycroft: in the big one i ony use simple green
04:55 PM XXCoder: roy likely though for glasses or something thats still plenty
04:56 PM roycroft: and i don't have a glass "tub" that would fit in it nicely
04:56 PM roycroft: btw, concentrated, but not full-strength, simple green in a heated ultrasonic cleaner is great for paint stripping
04:57 PM internut: stripping?
04:57 PM XXCoder: removal of paint
04:58 PM internut: I dated a stripper once
04:58 PM internut: she worked in a print shop
04:58 PM internut: her job title was 'stripper'
04:59 PM roycroft: you know, it just occured to me that if i got my sheldon horizontal mill working, between it, my lathe, and my drill press, i could probably make most of the parts i need to do the cnc conversion on the mill/drill, and avoid all that disassembly/reassembly stuff
05:00 PM roycroft: i should revisit that project
05:00 PM roycroft: i think that after i get the stuck taper pin removed, it should be fairly straightforward to get that machine operational
05:01 PM roycroft: and it would be an awesome machine to have running
05:06 PM unterhaus: new iphones don't charge from a normal usb? That stinks
05:10 PM internut: they have their own connector
05:11 PM internut: they've had it for some time
05:11 PM XXCoder: dont buy apple
05:11 PM internut: why not?
05:11 PM internut: I like their laptops
05:12 PM XXCoder: cool
05:12 PM internut: I have an iPhone because I needed to use an app that didn't have an android version
05:13 PM internut: it's a 6S and uses the same connector as the 12
05:14 PM XXCoder: only apple product i own is keyboard. its over 10 years old
05:14 PM roycroft: i have a
05:14 PM internut: frankly, the apple connector is better than the Micro-USB
05:14 PM roycroft: n iphone 6 and it uses that new connector that apple use for their stuff
05:14 PM roycroft: but the cable is standard usb on the power supply end
05:14 PM XXCoder: i have fewer and fewer devices using micro0usb
05:14 PM internut: micro usb was troublesome
05:14 PM roycroft: and on the phone it's the same connector that's on my ipad
05:15 PM snakedGT is now known as snaked
05:15 PM roycroft: i'm not excited that apple use odd connectors on their devices, but as long as they're standard connectors on the other end i don't mind it too much
05:16 PM internut: yeah, I bought a bunch of cables with the apple connector, they were pretty cheap
05:16 PM internut: my wife and my son have iPhones
05:17 PM internut: they're saying we could get 2 feet of snow here
05:17 PM roycroft: i'm pretty invested in apple products for desktop/laptop/portable devices
05:17 PM roycroft: they run unix
05:17 PM roycroft: and have apps
05:17 PM roycroft: and they work really well
05:18 PM internut: I was a lead developer on Comcast's CloudDVR
05:18 PM roycroft: i'm still struggling with my debian laptop
05:18 PM internut: it ran in Linux containers
05:18 PM roycroft: it kind of works, but it's really clunky to use
05:18 PM roycroft: a macbook pro just works
05:18 PM internut: but also ran, without modification, on my laptop
05:18 PM roycroft: i have vmware fusion on all my macs
05:19 PM roycroft: so when i need to run windows or linux apps i can easily do so
05:19 PM internut: Honestly, I haven't needed to run any windows apps in forever
05:19 PM internut: most linux stuff runs on OSX
05:19 PM roycroft: anyway, edge sander guy is coming over in an hour, and i need to go to market, so i should head out shortly
05:19 PM roycroft: i use autocad and solidworks almost every day
05:20 PM roycroft: solidworks is not available for macos
05:20 PM internut: oh, I don't use solidworks
05:20 PM roycroft: and i don't want to pony up $5k to buy autocad that runs natively on macos
05:20 PM roycroft: my old version of autocad (2008) runs just fine for me
05:20 PM roycroft: and i don't have to pay for upgrades/support
05:20 PM internut: I use OpenSCAD for all my 3D stuff
05:21 PM roycroft: i'm not ready for that yet
05:21 PM internut: OpenSCAD?
05:21 PM roycroft: it would take too long for me to draw anything more than the simplest parts
05:21 PM roycroft: yes
05:21 PM roycroft: because openscad is not very efficient until one build up a decent macro library
05:21 PM internut: I thought it was the dumbest thing when I first looked at it
05:22 PM internut: now I love it
05:22 PM roycroft: it's a great app
05:22 PM internut: but, I'm probably doing pretty simple stuff compared to what you're doing
05:22 PM roycroft: and if i invest a little time in it here and there, eventually i'll find it efficient enough to use for designing real parts
05:23 PM roycroft: well i do fairly simple stuff as well, but even the simple stuff is complicated enough for openscad to be a bit onerous
05:23 PM roycroft: these jigs i'm taking about would be a perfect application for it though
05:23 PM internut: I write code for a living
05:23 PM internut: so, it wasn't too hard to learn
05:23 PM roycroft: i did, back in the 1970s
05:24 PM internut: one little trick is
05:24 PM roycroft: but that's not my issue
05:24 PM roycroft: it's not difficult to learn at all
05:24 PM internut: I have made a lot of brackets and clips
05:24 PM roycroft: it's that the primatives are very primative
05:24 PM internut: I like to model the thing that's held in the bracket, and then subtract it from something larger
05:25 PM roycroft: so designing a screw, for example, requires writing quite a bit of code
05:25 PM internut: sometimes I model the thing, and make a bigger one and subtract the actual size one
05:25 PM roycroft: whereas in solidworks i just pull up the screw library, select the desired parameters, and place the screw in the model
05:25 PM internut: yeah, Solid works is a MUCH more comprehensive tool
05:25 PM roycroft: once i draw the screw in openscad and save it as a macro, i can do essentially the same thing
05:25 PM internut: there's no doubt
05:26 PM roycroft: but i have to code that screw the first time, and that's a fair amount of work
05:26 PM roycroft: and when i'm done with that
05:26 PM roycroft: i need a nut
05:26 PM roycroft: and a washer
05:26 PM roycroft: and thousands of other parts, over time
05:26 PM roycroft: each of which has to be coded once and saved as a macro
05:27 PM roycroft: solidworks without the parts library would be the same thing
05:27 PM roycroft: but solidworks has a parts library
05:27 PM roycroft: and for what's missing, mcmaster-carr fills in nicely :)
05:27 PM internut: Yeah
05:27 PM internut: OpenSCAD is a toy compared to SolidWorks
05:28 PM roycroft: well it's not something that should be compared to solidworks
05:29 PM internut: I still love it
05:29 PM roycroft: that wasn't a dis
05:29 PM roycroft: it's just a statement of fact
05:30 PM internut: here's my first OpenSCAD project: https://panicattackpictures.com/pan-tilt/index.html
05:30 PM roycroft: the two apps are barely related
05:30 PM internut: A pan-tilt-slide system for shooting time-lapse video with camera moves in it
05:30 PM internut: (maybe I showed you this before?)
05:30 PM roycroft: i hadn't seen it before
05:31 PM internut: and a video shot on it: https://youtu.be/9kqBcZl1I98
05:31 PM roycroft: that white part is probably about 150 lines of code
05:31 PM perry_j1987: man tap magic smells good
05:31 PM internut: I was at a friend's house and played with a puzzle he had
05:32 PM internut: I went home and designed and 3D printed one
05:32 PM roycroft: abom loves the smell of it, perry_j1987
05:32 PM roycroft: he talks about how much he loves the smell every time he uses it
05:32 PM perry_j1987: lol
05:32 PM internut: then I realized that with OpenSCAD, I could animate it pretty easily
05:32 PM internut: https://youtu.be/e9qaZdl_jjI
05:32 PM roycroft: i've never used it, so i'm missing out, i guess
05:32 PM perry_j1987: put little dab behind the ears and im good to go for the day lol
05:32 PM roycroft: anyway, i'm off to market
05:32 PM internut: jiggity jig
05:38 PM _unreal_: so my laser is operational. still having issues with the limit switches but other thennot being able to home. its for the most part work. I am having issues with the z motor though
05:38 PM _unreal_: its an addon of my own design.
05:44 PM perry_j1987: i need to get some chairs in the shop lol
05:44 PM _unreal_: how about you just sit your ass down
05:44 PM perry_j1987: metal shavings
05:46 PM perry_j1987: lol
05:48 PM _unreal_: ?
05:48 PM _unreal_: random?
05:48 PM perry_j1987: there are metal shavings on the floor
05:48 PM _unreal_: or I just dont tget it
05:48 PM perry_j1987: cant sit my ass on it
05:48 PM _unreal_: oh... ya details I didnt know
05:49 PM _unreal_: finally just finished cleaning the @#$@#$# dbl sided stick tape foam. stuff off of my cnc ready to put more down :)
05:50 PM perry_j1987: what is the foam tape for
05:51 PM _unreal_: holding parts down
05:51 PM perry_j1987: with foam tape?
05:51 PM _unreal_: yes
05:51 PM perry_j1987: why
05:51 PM _unreal_: if I miss a PCB board
05:51 PM _unreal_: I always use that stuff
05:51 PM _unreal_: if I'm milling face board
05:51 PM _unreal_: ahh
05:51 PM _unreal_: dont know the name
05:51 PM perry_j1987: i always used masking tape or blue painters tape
05:51 PM perry_j1987: to the bed and the pcb and some superglue between them
05:52 PM perry_j1987: easy to remove the tape that way
05:54 PM _unreal_: https://www.cspusa.net/images/contentimages/images/maxresdefault.jpg
05:54 PM _unreal_: yes but I cant mill though it
05:55 PM _unreal_: too little margin for error
05:55 PM _unreal_: this kind of board https://www.cspusa.net/images/contentimages/images/maxresdefault.jpg
06:09 PM JT-Cave: finally got building a damn deb down pat
06:12 PM Tom_L: sounds like it may have been giving you a little grief
06:12 PM JT-Cave: it's been a pain in the ASS for a long time
06:13 PM JT-Cave: all the tools are half broken or only work some secret way
06:13 PM JT-Cave: looks like rain here till Tuesday...
06:13 PM Tom_L: same
06:14 PM Tom_L: or at least for a day or two
06:15 PM roycroft: we shall allegedly have sunny skies through the week's end
06:16 PM roycroft: with temperatures climbing to the upper teens
06:17 PM JT-Cave: not sure what that is...
06:18 PM Tom_L: yeah i've had enough of the teens for quit some time
06:18 PM roycroft: and they're just beginning here
06:18 PM roycroft: the real teens
06:19 PM jym: and I have 6" of snow since this morning and still going
06:35 PM roycroft: we had a wind/hail/sleet storm yesterday that came out of nowhere and destroyed my patio gazebo and my grill gazebo
06:35 PM roycroft: one minute it was sunny, about 15 degrees, and nice and calm
06:35 PM roycroft: three minutes later it was about 8 degrees and sleet was coming down
06:35 PM roycroft: a minute later and huge balls of hail pelted my property
06:36 PM roycroft: about 2cm of icy hail balls built upon the ground
06:36 PM roycroft: then five minutes later it was sunny and 15 degrees again
06:36 PM roycroft: in other words, it is march
06:37 PM roycroft: we get colorado weather one month out of the year
06:57 PM roycroft: edge sander is sold
06:58 PM roycroft: that's pretty amazing - it took two days to sell it
06:58 PM roycroft: i thought it would take a lot longer
06:58 PM roycroft: i guess the right buyer was reading cl at the right time
07:01 PM XXCoder: oven is fixed. wheeee
07:03 PM roycroft: btw, my intuition seems to be right - i posted the sander on cl sunday night, and wondered out loud at the time if that was not a bad time to post in tools for sale
07:03 PM roycroft: and i heard nothing
07:03 PM roycroft: today i renewed the post at about 6:30 am
07:04 PM roycroft: and got a phone call just after 8 from the guy who was just here, and an email from another guy about an hour later
07:04 PM roycroft: so no more posting on sunday night
07:05 PM roycroft: the absolute best time to post tools for sale on cl is about noon on a friday that is the 5th of the 20th of the month
08:24 PM unterhaus: I always wanted my ebay auctions to end on Friday at noon
08:36 PM roycroft: if i'm honest, i've never put anything up for auction at ebay
08:36 PM roycroft: i've always been a buy it now person
08:36 PM roycroft: i do have a couple items that i'm considering auctioning
08:36 PM roycroft: or at least a combination auction/buy it now listing
08:37 PM -!- #linuxcnc mode set to +v by ChanServ
08:37 PM roycroft: so i've never concerned myself about ending times on ebay
08:37 PM roycroft: with cl, posting time makes a big difference for sure
08:38 PM roycroft: i just got ahead of myself on sunday - i was inspired over the weekend to do the sale, and as soon as i snapped the pics i listed the machine
08:40 PM roycroft: and the machine i just sold is not a weekend warrior item, so timing the listing to coincide with pay day was not important
08:40 PM roycroft: the guy who bought it has a trailer fabrication shop, and will be using it for his business
08:40 PM roycroft: so any weekday would be fine to list it
08:40 PM roycroft: just not on the weekend
