02:14 AM Deejay: moin
02:53 AM sorki is now known as srk
04:16 AM Loetmichel: *GAH* WHY? Coworker just came around hanging up A3 papers with "WHEN PACKING STUFF, LOOK ON THE DELIVERY SLIP AND CHECK THE AMOUNT!" in red... Appears someone sent some devices to a customer and packed our prototypes alongside as well. So not only we have sent two units to much, we dont have a reference ow to build more as well. Head->desk :(
04:26 AM XXCoder: shouldnt they ship it back?
04:27 AM Loetmichel: yep, but we have to build more NOW. and the reference is in france...
04:28 AM XXCoder: ahh damn
04:28 AM Loetmichel: always something here.
04:29 AM Loetmichel: not a day that works without hickups. makes the job interesting but also stressful. :)
04:29 AM XXCoder: yeah
04:30 AM Loetmichel: and slowly but surely the stress is getting to me. Already caught myself overreacting a few times in the last months to a degree that i left some Coworkers frightened because they are not used to me exploding.
04:30 AM Loetmichel: not a good thing
04:31 AM Loetmichel: <- is getting quite "shortfused" lately
04:31 AM XXCoder: need some vacation
04:31 AM XXCoder: problem with being irreplacable, you have hard time havign a week off
04:32 AM Loetmichel: indeed
04:34 AM XXCoder: making cross table. interesting. https://youtu.be/BojSiUFk6ys
04:38 AM XXCoder: I wouldnt call it "flat" but good enough for drill press cross table
04:40 AM Tom_L: morning
05:37 AM JT-Cave: morning
10:22 AM veegee: Went to the local hydraulic supply store hoping they'd be decent. Nope, just a bunch of hicks overcharging
10:23 AM veegee: For a 1m pressure washer hose with NPTF ends, they charged me $50 initially. I was like "WTF" (in a nice way) and pointed them to what they should actually cost
10:23 AM veegee: like in the $25 range tops
10:24 AM veegee: They reduced it to $38 and I said I can't understand what part of this costs so much. The hose ends are < $10 tops and 1m of pressure washer hose costs like a dollar
10:24 AM veegee: Princess auto will crimp for free, I just wanted to try something else local
10:24 AM veegee: And the fuckwit said "princess auto is crap"
10:24 AM veegee: lol they have the _exact_ same crimping machine as these guys
10:25 AM veegee: then he made some other excuse about them not using "bite to wire" fittings and "that's why they blow out all the time"
10:25 AM veegee: I've literally _never_ had a hydraulic hose from princess auto blow out. And I just checked, _all_ their fittings are bite to wire type
10:25 AM veegee: Time to write a friendly review on google about these fine gentlemen
10:27 AM veegee: They're the only hydraulic hose/fitting supplier in Toronto. Their website is absolute trash: http://hosesupply.ca/
10:28 AM veegee: Not sure how they got 16 reviews with an average of 4.5/5 stars. My review should make enough of a mark to cause them to hopefully change their aggressive behaviour
10:32 AM gregcnc: you still spent your money there?
10:37 AM veegee: I should have walked out, but I needed that hose today
10:37 AM gregcnc: I'm thankful when that happens
10:37 AM veegee: I really don't like big chain stores, but damn, princess auto does so many things right
10:38 AM veegee: They don't treat their customers like pieces of shit, amazing return policy, really good prices
10:39 AM veegee: But emphasis on not treating their customers like shit. I've been treated well every single time by them and they even honour their sale prices a month after the sale ends if you just mention it at the checkout counter
10:39 AM veegee: And the sale price is always significant, like 50% off
10:39 AM roycroft: before you leave a scorching review, engage management
10:39 AM veegee: Yeah that's the plan
10:39 AM roycroft: you may just have encountered a bad sales person
10:40 AM gregcnc: is it like a harbor freight?
10:40 AM roycroft: not a bad company
10:40 AM veegee: I'm going to call them first and clarify
10:40 AM veegee: gregcnc yeah princess auto is the Canadian equivalent of harbour freight
10:40 AM roycroft: management will let you know if this is an isolated or systemic behavior
10:40 AM veegee: gregcnc but not sure what harbour freight's customer service reputation is
10:41 AM roycroft: harbor freight's customer service is spotty and random
10:41 AM roycroft: and in large part depends on whether you give them your phone number when they demand it
10:41 AM roycroft: if you don't they're almost invariably jerks
10:41 AM gregcnc: 86753ooooohhhh9
10:42 AM roycroft: harbor freight use the tandy/radio shack model - employees' performance reviews place a heavy ranking on percentage of phone numbers captured
10:42 AM veegee: damn that's miserable
10:43 AM roycroft: i don't withhold to punish the employee
10:43 AM roycroft: i withhold because i value my privacy, and see this as a harbor freight-employee issue, not a cutomer-employee issue
10:43 AM roycroft: customer
10:44 AM roycroft: wow
10:44 AM gregcnc: how bad was the experience, you asked for a hose, and they whipped you with it?
10:44 AM roycroft: my county health department just elminiated preregistration/screening for covid-19 vaccines
10:44 AM roycroft: as of today you just go to the website and schedule an appointment
10:44 AM roycroft: i'm glad i already have one
10:45 AM roycroft: it's going to be a zoo today
10:45 AM unterhaus: We have a Parker store in my little town in Central Pennsylvania
10:45 AM unterhaus: although I don't think they will build a hose on the spot
10:45 AM unterhaus: have to come back
10:46 AM * roycroft wonders how there can be only one hydraulic hose supplier in all of gta, when there are at least four in much much smaller eugene
11:03 AM veegee: There are more in the greater toronto area, but I didn't want to drive very far
11:04 AM unterhaus: I know there is a garage here that will make hoses, probably more than one. Limited selection of ends though
11:04 AM unterhaus: if you need NPT ends, you're good. But Canukistan might not use 'murican threads
11:06 AM JT-Shop: there is prob 50 places here that make hyd hoses
11:06 AM JT-Shop: and one place that makes hose... Gates
11:16 AM roycroft: my county is moving from moderate risk to low risk on friday
11:17 AM roycroft: we'll be having live concerts and the like before long
11:17 AM * roycroft will be so happy to see life return to some semblence of normalcy
11:34 AM unterhaus: JT-Shop, the neighbor is putting in a building and my wife is afraid it's a chicken coop
11:35 AM unterhaus: I don't think chickens are legal here, next township over legalized them
11:37 AM JT-Cave: why is she afraid?
11:38 AM roycroft: most incorporated communities in the us allow hens, but the majority outlaw roosters
11:41 AM unterhaus: JT -- noise I guess
11:42 AM unterhaus: we had chickens when I was a kid, but the rooster had to go "live on a farm"
11:42 AM JT-Cave: hens can be a bit noisy but not like a rooster
11:44 AM roycroft: hens can bother your next door neighbor
11:44 AM roycroft: roosters can bother your entire block
11:45 AM JT-Cave: where I live there are no blocks...
11:46 AM unterhaus: I suppose she could be right, but so far it's all just screened-in, no place to roost
11:46 AM roycroft: maybe it's a bunny hutch
11:47 AM unterhaus: it has a floor, which seems weird for animal husbandry
11:48 AM unterhaus: but it would be a good way to raise snakes and bunnies underneath. Probably one or the other
11:48 AM Tom_L: ask em wtf they're up to
11:48 AM roycroft: chat with neighbors?
11:49 AM roycroft: how quaintly 20th century
11:49 AM Tom_L: no, txt them
11:49 AM unterhaus: I was, but it's about a half mile walk from here
11:49 AM Tom_L: while you're both standing on your porches
11:49 AM roycroft: they're a half mile away and your wife is worried about a little noise?
11:49 AM gregcnc: just call the city and let them sort it out then post the confrontation on tiktok
11:49 AM unterhaus: actually wanted to ask if I could have some wood they are letting rot at the fence line
11:50 AM unterhaus: they are back yard neighbors on another street
11:50 AM unterhaus: I"m not walking through their yard, probably eat lead
11:51 AM Tom_L: take a white flag with you
11:52 AM unterhaus: I'm not that curious, really
11:52 AM Tom_L: aww, we wanted you to have a story to tell us
11:52 AM unterhaus: you just wanted me to get shot
11:53 AM * Tom_L snickers
11:53 AM Tom_L: what's a little lead among neighbors?
11:54 AM unterhaus: if it's bothersome, the people next to them will complain, they bothered me over my raised garden
11:54 AM * JT-Shop makes a mental note to clean the bandsaw more often... like before it becomes a solid lump of chips
11:55 AM unterhaus: I shouldn't say bothered, the husband asked me what I was building in case he wanted to bother me about it
11:55 AM gregcnc: so he conversed with you
11:55 AM unterhaus: he just made sure I wasn't building a chicken coop
11:57 AM unterhaus: then he made fun of it because it was only 4'x8'
11:57 AM gregcnc: did you show him up?
11:58 AM unterhaus: gardening around here is not easy, lots of hungry critters.
11:58 AM unterhaus: I have 2 neighbors that have abandoned gardening because it's a lot of work just to feed the rabbits
11:59 AM unterhaus: and deer
11:59 AM miss0r: feed rabbit, eat rabbit.. sounds like gardening to me
11:59 AM miss0r: Just with an extra step to make it tasty
11:59 AM gregcnc: some lead poisoning
11:59 AM miss0r: gregcnc: Use full metal jacket...
12:00 PM gregcnc: come on we know you can't even have slingshots over there
12:00 PM miss0r: Hey!... you have a point
12:00 PM gregcnc: lol
12:00 PM miss0r: a rock thrown with high accuracy never gave anyone food poisoning :)
12:01 PM miss0r: well.. perhaps food poisoning. I meant to say lead poisoning
12:03 PM miss0r: probably a good thing we can't have guns 'round here. I would be the first to dig and sandbag reinforce a 50cal machinegun nest in my front yard
12:03 PM miss0r: because reasons :)
12:03 PM gregcnc: are you running production of those filter adapters? Work holding for production is a big part of the game
12:03 PM miss0r: production is a strong word. Its s small batch of 5
12:03 PM gregcnc: ah ok
12:04 PM miss0r: and by the looks of it, they are selling like crazy. If demand keeps up, I will outsource it
12:04 PM miss0r: (to a local tool shop)
12:04 PM JT-Shop: man that 3/4 pitch blade flat cuts through 12" steel like butter
12:05 PM miss0r: JT-Shop: Yeah that is a nice pitch. I have that on my cold saw. (with a spinning disk sorta think.. I'm not sure what the term is in english)
12:06 PM miss0r: gregcnc: But the production has not been going too well honnestly. I don't know why these units kick my ass. I've scrapped more units than I have completed - by far even :)
12:07 PM JT-Shop: cold saw
12:07 PM gregcnc: i've caught some of the issues here. you can't get enough wrench clearance by milling that slot with the part on it's side?
12:08 PM JT-Shop: I normally have an 8/12 pitch on the bandsaw but for thicker stuff change it
12:08 PM miss0r: gregcnc: I could. But it does not look as nice :)
12:09 PM miss0r: JT-Cave: The issue with chip buildup is much more pronounced with a circular blade, as the traveled distance for each tooth before it can dump its chip is longer. I wish I could fit a proper bandsaw in here :)
12:09 PM miss0r: gregcnc: I am hoping we can continue this conversation later. I have to run back in to the family now. Talk to you later
12:09 PM gregcnc: if the volume was there I'd might try one of those insert type saws
12:30 PM * JT-Shop sets up the VMC for some lights out machining
01:55 PM roycroft: i have to make a tool to adjust the parallelism on my new jointer
01:55 PM roycroft: it sounds like it's time to finally finish the heat treatment kiln
01:59 PM roycroft: the tool won't really need to be heat treated, but if make it out of tool steel it will be more durable than mild steel, and if i'm going to make it out of tool steel i might as well harden and temper it
02:00 PM * roycroft is good at justifying things
02:01 PM XXCoder: lol
02:02 PM roycroft: well that heat treatment kiln has been partially disassembled and filling up a workbench in my fabrication shop for close to a year
02:02 PM roycroft: i really do need an excuse to finish it
02:02 PM roycroft: anyway, it's lunch time, so i get to go test my new jointer for the first time, even though the beds are not quite perfectly parallel yet
02:14 PM XXCoder: yay :)
02:20 PM roycroft: well, even with the beds not parallel, i was able to joint a long, twisted piece of ash faster than i could on my old jointer
02:20 PM XXCoder: awesome :D
02:20 PM roycroft: and it's definitely a different class of machine
02:21 PM roycroft: it's only 2" wider than the old one, but it's like the difference between a mill/drill and a bridgeport class mill
02:21 PM roycroft: as soon as i started working with it i remembered my old 8" jointer and now much better it was than the 6"
02:21 PM roycroft: and i had my old one before spiral/helical cutterheads were around
02:21 PM roycroft: it had straight knives
02:22 PM roycroft: i don't like the tinny sheet metal vibration sounds from the base though
02:22 PM roycroft: i wonder if there's something equivalent to dynomat that i can procure locally
02:22 PM roycroft: er, dynamat
02:27 PM roycroft: actually, i think i have some dynamat in a box of miscellaneous vw bus parts
02:27 PM roycroft: it's probably 20 years old, so no idea if it is still sticky
02:51 PM NoGodDamnIdea: hey guys
02:53 PM XXCoder: hey
02:55 PM miss0r: gregcnc: Are you still around?
02:56 PM Tom_L: roycroft, need a stub shaft for aligning the clutch? still got one in my toolbox
02:56 PM Tom_L: along with a few other 'specialty' tools
02:57 PM Tom_L: they just cancelled the mask mandate in this county
03:12 PM roycroft: i need a pin spanner with rectangular pins
03:13 PM XXCoder: tom hope cases dont bloom in there :(
03:13 PM roycroft: we'll be masking until we reach herd immunity
03:13 PM Tom_L: they've been pretty low here
03:13 PM roycroft: which will probably be around the end of the year
03:13 PM Tom_L: pin spanner?
03:13 PM roycroft: especially with lunatics like my boss running around
03:13 PM Tom_L: for what?
03:14 PM roycroft: the jointer has parallelogram ways
03:14 PM roycroft: it's for adjusting them
03:15 PM roycroft: i'd probably be best off making one out of a socket
03:15 PM roycroft: if i get one that's the correct size
03:15 PM roycroft: but then i would not have the excuse to finish the heat treatment kiln
03:16 PM roycroft: https://cdn0.grizzly.com/manuals/g0490x_m.pdf
03:17 PM roycroft: page 41 shows the eccentric bushing adjustment
03:17 PM roycroft: one of my adjustable pin spanners might fit that, but i don't think so
03:17 PM roycroft: i'll definitely check before making a tool
03:18 PM roycroft: this is an adjustment i should need to make once every few years - it's hard to justify making a special tool for that
03:20 PM Tom_L: you'd forget where it was by then anyway
03:22 PM roycroft: actually, if i make a special too for that, i'd store it inside the jointer cabinet
03:22 PM roycroft: i'm pretty good about keeping machine-specific tools with the machine
03:23 PM roycroft: and i already need to make a little storage bin to attach inside the jointer stand to hold extra inserts, guard springs, etc.
03:24 PM roycroft: too much of my life has been wasted looking for things like that
03:24 PM roycroft: i'm finally learning to take the extra time to find proper homes for that kind of stuff
03:24 PM unterhaus: I'm horrible about keeping tools with their machines. I have some wrenches that were obviously for a woodworking tool, but I have no idea which ones
03:25 PM unterhaus: OTOH, the wrenches for the tablesaw are hanging on the front on one of those magnetic tool holder strips
03:25 PM roycroft: i used to be bad about that stuff
03:25 PM roycroft: but i'm very good about it now
03:29 PM XXCoder: roycroft: can always make something to hold it to joiner
03:29 PM XXCoder: not too accessable, but if its not often used..
03:29 PM roycroft: sure, but i have other things to store that go with it as well
03:30 PM roycroft: so i'll just make or buy a little box to hold the stuff, and figure out a way to attach the box to the inside of the cabinet
03:31 PM roycroft: i'm in the middle of desiging the mobile base for the machine - i may just weld in a couple extra brackets to support the toolbox
03:36 PM veegee: Dog damn, remember when I posted about that hydraulic fitting that had tapered threads AND a flare?
03:36 PM veegee: Turns out it was just a standard NPT swivel
03:37 PM veegee: Albeit the threads were tapered from deformation
03:37 PM veegee: I couldn't understand why it needed a tapered thread _and_ a flare-like face to seal
03:38 PM roycroft: especially since it's all but impossible to make both types of seals work at the same time on the same fitting
03:38 PM veegee: Turns out the sealing is just from the flare-like face and the threads are supposed to be straight threads (not tapered), but engage with a MNPT face
03:38 PM veegee: so it pretty much behaves like a flare fitting
03:38 PM roycroft: so they're really supposed to be nps, not npt
03:38 PM veegee: yeah
03:38 PM veegee: they are indeed NPS
03:39 PM veegee: the male NPT fitting it's supposed to attach with also has an inner bevel
03:39 PM veegee: so it seats against that flare better than a sharp edge would
03:40 PM veegee: Now I'm wondering why air line fittings aren't all like that. Why do we have these damn expensive pipe unions when we can just use swivel fittings like that instead?
03:40 PM veegee: It's a lot cheaper than buying pipe unions for every joint
03:40 PM veegee: I'd much rather deal with flare type seals than tapered threads
03:41 PM roycroft: taper threads can be serviced more times than flare fittings without going out of spec
03:41 PM roycroft: and unions an almost indefinite number of times
04:00 PM roycroft: well this is nice
04:00 PM roycroft: i've wanted to build a metal storage rack outside my fabrication shop for years, but haven't wanted to spend any money on it
04:00 PM roycroft: my boss just told me that i can have all the ladder rack from the data center we're vacating if i'll haul it away
04:01 PM roycroft: it will be a little funky for a metal storage rack, but it should work well
04:01 PM roycroft: it's thickly powder coated, so i'll have to some serious grinding on the bits i need to weld up
04:01 PM roycroft: but it's free and it's strong
04:01 PM NoGodDamnIdea: so _unreal_ i used the settings you told me but the machine acts weird
04:02 PM roycroft: he also told me i can start catching up on my vacation time that i missed out on last year
04:02 PM roycroft: so i have three weeks from last year, and three weeks from this yeaer
04:02 PM roycroft: as soon as the move out of the data center is complete i can start taking vacation days at least one day/week for now
04:02 PM roycroft: and a full week some time in may
04:23 PM _unreal_: NoGodDamnIdea, define weird
04:23 PM _unreal_: and I litterally JUST sat down
04:24 PM _unreal_: just got home, just watered a few plants out side has not rained in like 3 weeks
04:24 PM _unreal_: here in south florida
04:24 PM _unreal_: NoGodDamnIdea, hello?
04:24 PM NoGodDamnIdea: lemme upload some pics and a vid
04:24 PM NoGodDamnIdea: yes yes I am here
04:24 PM _unreal_: NoGodDamnIdea, god damn it put down the glass of water
04:24 PM _unreal_: heh
04:24 PM NoGodDamnIdea: nah this time its my broken heart
04:25 PM _unreal_: at least you have two replacement girl friends just an arms reach away
04:25 PM _unreal_: acting weird, is the machine MOVING or is it vibrating shuddering
04:26 PM NoGodDamnIdea: you will understand soon let me upload
04:27 PM _unreal_: I can drink faster then this is uploading LOL
04:28 PM _unreal_: speaking of thinking I'm going to reload my gin/tonic
04:28 PM NoGodDamnIdea: yeah me too
05:20 PM unterhaus: maker license for solidworks is reportedly $100, very tempting for me
05:21 PM XXCoder: look into terms
05:21 PM XXCoder: can you sell stuff?
05:21 PM XXCoder: so on
05:27 PM roycroft: solidworks is a great 3d modeling app
05:27 PM roycroft: it has a rather steep learning curve though
05:27 PM roycroft: i would argue that freecad has a steeper learning curve
05:27 PM Tom_L: https://www.solidworks.com/support/community-download#no-back
05:27 PM XXCoder: probably
05:27 PM Tom_L: https://www.reddit.com/r/maker/comments/a9iw5i/get_solidworks_maker_licence_for_free/
05:27 PM roycroft: but solidworks is not somethng you just install and start making complex models the first day
05:27 PM XXCoder: i cant run solidworks in linux so its moot point for me
05:28 PM roycroft: so be prepared to invest some time in it if you decide to get it
05:28 PM Tom_L: it's quite similar to catia
05:28 PM Tom_L: i happen to like catia better though
05:28 PM roycroft: i've never used catia
05:29 PM roycroft: i hear good things about it
05:29 PM Tom_L: it's a high end cad
05:29 PM roycroft: iirc catia is more popular in the aviation industry
05:29 PM Tom_L: aviation, auto etc
05:30 PM Tom_L: handles assemblies better
05:30 PM XXCoder: has linux version?
05:30 PM Tom_L: no
05:30 PM XXCoder: hmm too bad oh well
05:30 PM Tom_L: and now it's all cloud based
05:30 PM XXCoder: lost a lot of points
05:31 PM Tom_L: the seat my bud got years back was $75k iirc
05:31 PM Tom_L: with a sun pc
05:31 PM roycroft: we paid around $6k for the solidworks license i use
05:32 PM roycroft: which was solidworks 2012 with most of the extras
05:32 PM Tom_L: yeah, that's about what my smartcam was way back when
05:32 PM roycroft: that's what i still use
05:32 PM Tom_L: same here
05:32 PM roycroft: i don't use it at work any more, so my boss did not pay for support/upgrades
05:33 PM Tom_L: i did programming for my friend and it paid for itself the first year i had it
05:33 PM roycroft: so i've been dreading the next step in my blasting cabinet refurbishment - cleaning up the remnants of the foam seals between the parts
05:33 PM roycroft: but i went out a while ago, put a wire cup on an angle grinder, and cleaned up the funnel in about 10 minutes
05:34 PM roycroft: it went way better than i thought it would
05:34 PM roycroft: i like when that happens
05:36 PM roycroft: i'm not sure if i should get that solidworks maker version, even though it comes with the cam software
05:36 PM roycroft: it can't be used commercially, although i'm not sure what d'assault systems consider commercial
05:37 PM roycroft: iirc, the maker version of fusion is ok to use for low-volume commercial shops
05:37 PM roycroft: like <$100k/year or something like that
05:38 PM roycroft: gross sales, that is, not grosss margin
05:40 PM XXCoder: roy though they did lot of cuts on free recently
05:40 PM XXCoder: only 10 parts something? active
05:40 PM * roycroft also wonders what the difference is between a "hobbyist" and a "maker" in d'assault's eyes, other than posting every minute of a "maker's" life on youtube
05:40 PM XXCoder: which makes some assemblies impossible to make
05:41 PM roycroft: as in almost all assemblies
05:50 PM _unreal_: I'm still trying to find the best usb cam. for my laser etchedr
05:50 PM _unreal_: etcher
05:50 PM _unreal_: greatest field of view as well
05:51 PM _unreal_: I'm looking at this one. https://www.amazon.com/ELP-Fisheye-170degree-Infrared-Housing/dp/B07DWWSWNH/ref=sr_1_34?dchild=1&keywords=fisheye+usb+camera&qid=1616561511&sr=8-34
05:51 PM _unreal_: and
05:51 PM roycroft: i bought a usb camera at the goodwill for $5 to monitor my 3d printer

05:51 PM roycroft: it was old and used
05:51 PM roycroft: but i can monitor the printer with it
05:51 PM * roycroft spends his money where it matters
05:52 PM _unreal_: roycroft, my cnc has a 21/24" work area
05:52 PM _unreal_: I prob need fish eye
05:52 PM _unreal_: but I'm looking at that 110 degree
05:52 PM _unreal_: view angle
05:52 PM _unreal_: and this is laser as well
05:53 PM roycroft: you'll buy a pos "router" from harbor freight to save a buck, then buy a top-of-the-line webcam to monitor your crappy router :)
06:21 PM _unreal_: at least I would be consistant :)
06:21 PM _unreal_: ;)
06:51 PM roycroft: i wonder if my spot welder would secure the wire mesh inside its frame for the blasting cabinet tray
06:51 PM roycroft: i had to cut the tray down to fit, since i lowered it 4" into the funnel, and now the wires are really loose
06:52 PM roycroft: i guess i can give it a go, and if it doesn't work, maybe pull out the tig welder
06:52 PM roycroft: i'm afraid my mig welder would burn the stuff up
07:08 PM rue_mohr: usb cables, how close can you get to a plasma cutter before it starts to twitch funny
07:25 PM roycroft: i've never had a plasma cutter twitch, funny or not, as i approached it
07:26 PM roycroft: even as i picked up the torch and powered it on
07:26 PM roycroft: perhaps plasma cutters fear you, but not me
07:27 PM roycroft: which makes one wonder if you are a serial plasma cutter abuser
07:29 PM rue_mohr: its the usb that would do the twitching
07:29 PM rue_mohr: electrical noise
07:29 PM roycroft: tell the usb to simmah down
07:29 PM roycroft: it's just plasma
07:30 PM roycroft: usb is surrounded by solids and gases, and sometimes liquids, and it is ok with all of those
07:30 PM roycroft: why should it freak out about plasma?
07:33 PM Tom_L: isn't it a high frequency?
07:33 PM Tom_L: i don't have one so i'm not sure
07:33 PM rue_mohr: small electrical signals and high power ZZZZZT dont go well both ways
07:33 PM rue_mohr: I dont either yet
07:40 PM roycroft: seriously though, people build cnc plasma cutters all the time - it should not be difficult to keep the torch side far enough away from the control side to avoid problems
07:44 PM internut: _unreal_ how about running flatcam on a mac
07:44 PM internut: ?
08:59 PM Bleepshop: Is 24 pins of I/O enough for CNC outputs and handwheel inputs ?
09:00 PM * Bleepshop is getting ready to hang together a bank of 3.3V<>5V level shifters and build a prototype interface.
09:03 PM _unreal_: flatcam on mac no idea
09:03 PM Tom_L: Bleepshop, maybe but doubtful
09:10 PM Bleepshop: Tom_L: Axises are X/Y/Z, so 3 step, 3 dir, 3 limit, 1 spindle, 1 coolant, 1 probe. Total of 12 and I think the handwheel uses 12 signal leads.
09:11 PM Bleepshop: Screw it, I'll shove the circuit to one end of the board and leave room to add a 7th shifter block just in case.
10:22 PM Tom_L: just saying, you end up using more than you think
10:23 PM Tom_L: need stepper driver enables?
10:23 PM Tom_L: estop?
10:24 PM Bleepshop: E-stop piggybacks on the handwheel wiring, I do need a 13th for the charge pump though.
10:26 PM Tom_L: estop should disable the stepper drivers and vfd
10:27 PM Tom_L: at least
10:27 PM XXCoder: isnt it better to just override steppers by estop so it locks in place and not just drop
10:28 PM Tom_L: if it's that big you should have a brake
10:28 PM Bleepshop: XXCoder: No way in hell will this do anything under the influence of gravity unless you chucked it out of a C-130. LOL
10:29 PM XXCoder: lol ok
10:29 PM Tom_L: as you build you learn to plan for the worst
10:30 PM * Bleepshop curses "WTF is my stock of perfboard ?"
10:30 PM Tom_L: i got some fr4 for you
10:31 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/etching/Copper1.jpg
10:31 PM Bleepshop: Tom_L: Woot! Do you ratsnest and route as well ? ;D
10:31 PM Tom_L: i used to
10:32 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/etching/etch6.jpg
10:32 PM Tom_L: not even sure what that was now
10:33 PM Tom_L: used to build avr programmers
10:34 PM Tom_L: was pretty good with eagle but i'd probably have to relearn it now
10:34 PM Bleepshop: Looks like an RJ-12 on the left side and a microcontroller in th middle.
10:35 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/boards/new_batch/DSC_0001.JPG
10:35 PM Tom_L: those were some programmer boards
10:35 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/boards/new_batch/USB_chips.jpg
10:35 PM Tom_L: i made a few
10:38 PM Tom_L: SOT23-6 http://tom-itx.no-ip.biz:81/~webpage/temp/tiny/tinyboard1.jpg
10:38 PM Tom_L: that's about as fine as i ever did by hand
10:43 PM Tom_L: Bleepshop, so you're planning to use the rpi4 gpio as the interface?
10:50 PM Tom_L: Bleepshop, have you seen these? http://store.mesanet.com/index.php?route=product/product&path=69_62&product_id=345
10:50 PM Tom_L: http://store.mesanet.com/index.php?route=product/product&path=69_62&product_id=338
10:50 PM Bleepshop: Tom_L: Gonna try it and see what ahppens.
10:51 PM Tom_L: connects to the rpi via spi
10:52 PM Tom_L: can expand the io if you need more via sserial
10:53 PM Tom_L: the heavy lifting is offloaded to it's fpga
11:18 PM XXCoder: hmm i might need to reoil some of bearings
11:18 PM XXCoder: filiment roller isnt working properly and jams sometimes lol
