12:06 AM pink_vampire: the tip of the indicator was too short, but it is M2! so.... https://i.imgur.com/6Spp4PR.png
05:25 AM Tom_itx: morning
05:26 AM XXCoder: hey
05:26 AM Tom_itx is now known as Tom_L
07:13 AM JT-Cave: mmm shrimp and grits for supper
07:31 AM perry_j1987: morning all
07:43 AM Centurion-Dan2 is now known as Centurion_Dan

08:31 AM gregcnc: pink_vampire video if you are going to make that saw cut on that spindle, the destruction should be heard here in chicago
08:32 AM gregcnc: you can't feed saws like endmills maybe 1/10-1/20 normal chipload and low RPM, <1000.
08:38 AM andypugh: pink_vampire: Going back that Mystery Lathe photo. For some reason it looks Australian to me. But it seems very unlikely that there would be an Aussie lathe in the US (where I believe yoiu are?)
08:41 AM gregcnc: which photo?
08:46 AM gloops: https://www.ebay.co.uk/itm/bridgeport-milling-machine/324227554670?
08:58 AM gregcnc: Mute this clip it's loud https://www.instagram.com/p/CBo6DsdppXE/
08:59 AM gregcnc: this is polygon turning. are the faces generated simply from the change ins radius or is there more complex speed syncing between the spindles?
09:07 AM skunkworks: That is cool
09:08 AM Tom_L: skunkworks, you got your work cut out now!
09:08 AM skunkworks: https://www.youtube.com/watch?v=H_zOoYeQqHY
09:09 AM skunkworks: I give up ;)
09:10 AM gregcnc: I guess I should just do the math in the Fanuc manuals to see what's needed
09:12 AM gregcnc: this is very fast, but depends on how accurate you need the flats to be, because they aren't
09:19 AM perry_j1987: skunkworks that is crazy
09:51 AM perry_j1987: eishhhh https://www.youtube.com/watch?v=XewCqAWXLhM that part moving all around when they are trying to machine it lol
09:52 AM Tom_L: too much gab
09:53 AM perry_j1987: was watching to get a peek inside the building
09:53 AM perry_j1987: use to drive by it all the time
09:56 AM perry_j1987: https://www.youtube.com/watch?v=aEm_X2wUfps lol
09:56 AM perry_j1987: robot hitting the mouse button cracked me up way too much
09:57 AM perry_j1987: looks like making paddle lock parts
09:58 AM gregcnc: happens even in "real" shops. close teh door, push the green button
11:16 AM perry_j1987: so no tie in with the robotic arm two separate ecosystems eh?
11:17 AM perry_j1987: i want to get one of these used kuka robot arms to play with some time
11:26 AM gregcnc: depends if the machine supports it
11:37 AM Tom_L: one of the workcell conveyors screwed up at my kid's work some time back and was sending pallets to the wrong machines
11:37 AM gregcnc: did it get fired?
11:37 AM Tom_L: no but it got fixed pdq
11:41 AM Tom_L: i think they had to fly somebody in for that one
11:52 AM skunkworks: there was a pbs program about computers when I was a kid - The intro or end of the show had a robot placing objects or something then at the very end - it unplugged itself.
11:54 AM Tom_L: is that like suicide?
11:55 AM skunkworks: My teenage self thought very deeply about it..
11:55 AM Tom_L: heh
11:55 AM perry_j1987: lol
12:11 PM Dolence: gregcnc got way better results
12:11 PM gregcnc: what did you do?
12:11 PM Dolence: changed resolution from 32 to 256 steps per mm
12:12 PM Dolence: and changed accelleration value
12:12 PM Dolence: it was too high, causing problems in corners and when doing briddges
12:13 PM Dolence: now I'm using 3200 steps per revolution / 16 microsteps
12:13 PM Dolence: It's very nice even on aluminum :D
12:13 PM gregcnc: yeah that makes sense
12:14 PM Dolence: thank you very much!
12:15 PM gregcnc: you're welcome. are tolerances OK?
12:20 PM Dolence: Didn't measured yet. I mainly use to cut parts for my own personal use
12:21 PM gregcnc: what is the resolution of the encoder on the motors?
12:21 PM Dolence: I'm building a large 3D printer (48x48cm useful table area)
12:21 PM perry_j1987: https://www.youtube.com/watch?v=ojWiY5KP3WQ fun watching all the parts climb out of the machine on their own
12:21 PM Dolence: I guess it's 1000
12:22 PM Dolence: Yeah, encoder resolution is 1000
12:22 PM Dolence: Is this ok?
12:23 PM Tom_L: plenty good yes
12:23 PM gregcnc: i'm just curious.
04:01 PM veegee: yay my new aircat die grinder arrived but I'm still sitting at the office
04:01 PM veegee: Can I blow into the air intake to make it spin? PLEEEEEEASE?
04:02 PM veegee: JUST ONCE I PROMIES
04:03 PM Tom_L: likely to void the warranty!
04:06 PM veegee: It's the aircat 6260 1hp straight die grinder
04:06 PM veegee: Feels nice and solid
04:07 PM CaptHindsight: FDM/FFF is so slow, why do people make printers with an area over a few cm^3?
04:08 PM CaptHindsight: over that size use SLA/LCD/DLP or SLS with multiple lasers
04:18 PM andypugh: It doesn’t matter how long it takes if you can sleep or watch TV at the same time.
04:19 PM veegee: Wow making the die grinder spin by blowing into it is quite the exercise for your diaphragm
04:20 PM CaptHindsight: I see some that will take days to use up the volume
04:20 PM veegee: so much airflow and pressure required
04:20 PM veegee: Well other than moisture, at least the tool is getting biological grade filtered air :D
04:27 PM JavaBean: CaptHindsight: check out the railcore2. not sure how long it would take to fill its full volume, but its rather fast
04:34 PM W1N9Zr0: CaptHindsight: just need a bigger hotend https://e3d-online.com/collections/hotends/products/supervolcano-upgrade-kit
04:50 PM andypugh: Tool-porn: https://www.workshopheaven.com/starrett-92-9-nine-inch-dividers.html That’s a _lot_ of money for some dividers.
04:52 PM XXCoder: ouch yeah
04:52 PM XXCoder: I bet its very stiff
04:54 PM andypugh: If I used a divider every day, rather than every year, I would be more tempted.
05:00 PM roycroft: i buy most of my starrett tools one ebay these days
05:01 PM roycroft: for usually about 1/4 what they cost new
05:01 PM XXCoder: some are fakies
05:01 PM XXCoder: expecially mitoyoto
05:02 PM XXCoder: fake ones dont actually do power management so it loses power in a month or so
05:02 PM XXCoder: while real ones can last year or 2 of usage
05:02 PM roycroft: i got a nice 4"/100mm mitutoyo digital caliper off amazon's warehouse site a couple years ago for just over $100
05:02 PM roycroft: their "warehouse" is open box/returns stuff
05:03 PM XXCoder: 4" pretty small
05:03 PM XXCoder: good if you make only small parts I guess
05:03 PM roycroft: the caliper i still had the factory shrink wrap on, but the shrink wrap was a bit torn
05:03 PM roycroft: i have some 6" ones
05:03 PM roycroft: but i find that most of what i measure with calipers is 4" or shorter
05:04 PM roycroft: and a 4" one fits in a pocket very nicely
05:04 PM XXCoder: nice
05:04 PM roycroft: it's a very useful and convenient size
05:04 PM roycroft: but it should not be one's only calipers - i'd say if you only had one, get a 6"
05:05 PM JavaBean: 6"??? i find my calipers a bit small, kinda want a 12"
05:05 PM XXCoder: lot depends on usercase
05:06 PM XXCoder: my 6" is all I need
05:12 PM roycroft: i think you'll find that 6" is the most common size dial/digital calipers
05:12 PM Loetmichel: on that account: i should order a dozen more $20 digital 6" calipers for the company. they tend to evaporate. :-)
05:14 PM roycroft: the only $20 ones i see around here are from harbor freight
05:15 PM roycroft: and they 1. burn through batteries like there's no tomorrow, because when you turn them off all that does is blank the splay
05:15 PM roycroft: 2. get full of crud right away and start giving inaccurate readings
05:15 PM roycroft: and 3. die an early and horrible death
05:16 PM XXCoder: Loetmichel: heavy workshop theft? doesnt sound good
05:16 PM roycroft: i'd probably go through at least a half dozen of them per year, and have replace the batteries almost every time i used them, if i kept with them
05:16 PM roycroft: so a quality set like the mitutoyo is actually a lot cheaper, even in the short term
05:16 PM XXCoder: roy yep they tend to use bad mitoyoto hack that dont do power management
05:16 PM roycroft: schook, xxcoder
05:16 PM roycroft: school
05:16 PM XXCoder: i threw away my old cheap one
05:16 PM roycroft: in his case the cheap ones make sense
05:16 PM XXCoder: indeed
05:16 PM roycroft: because they're going be stolen or damaged right away anyway
05:17 PM roycroft: and the cheap ones work ok for a couple weeks
05:17 PM roycroft: which is about how long they last in a school
05:17 PM XXCoder: my cheap one lasted a year or so
05:17 PM XXCoder: I had to reset zero each time I use it though lol
05:17 PM roycroft: i have a box of hem
05:17 PM XXCoder: it was such a bad one
05:17 PM roycroft: i need to get rid of them
05:17 PM roycroft: but they're not landfill material
05:17 PM XXCoder: turn them into dro thing
05:18 PM roycroft: so i just collect them in a box
05:18 PM XXCoder: or donate to schools
05:18 PM roycroft: they're all dead
05:18 PM andypugh: I like to have a 3” digital caliper in my workshop, next to the computer and on the electonics bench. I have several 6”, a 4” and a 12” too. Oh, I fogot the 3” in my desk drawer at work.
05:18 PM XXCoder: battery dead or just dead
05:18 PM roycroft: one of these days i'll remember to take the box with me when i got to recycle electronics
05:18 PM roycroft: 3" would be nice
05:18 PM roycroft: although i find the 4" to be a really handy size
05:18 PM XXCoder: 3" is nice but im maxed out on certified tools at shop so I cant get more
05:19 PM Loetmichel: XXCoder: nope.i found one in the coffee kitchen, one on the floor in the measurement chamber and one outside in the rain.
05:19 PM roycroft: 3" is even more pocket-size than 4"
05:19 PM XXCoder: maybe that guy hoped his caliper would grow in rain? ;)
05:19 PM Loetmichel: no theft. just lazy workers that "disapper" them in some remote corners
05:19 PM Tom_L: 8" is a fairly handy size
05:19 PM Loetmichel: we HAD 10 at one time though
05:19 PM roycroft: or maybe they break and the workers hide them
05:20 PM Loetmichel: no idea where the rest disappeared
05:20 PM roycroft: they go to that island where one sock out of every pair goes
05:20 PM Loetmichel: you cant break much on a 12 eur caliper
05:20 PM Loetmichel: yes, i think so
05:21 PM Loetmichel: ah, and i THINK i have one at home. freshly cleaned in the washing machine ;)
05:21 PM XXCoder: loet reminds me about that time I read about one nonmachinist borrowing a calibration set gage block. boss told him he can use it
05:21 PM XXCoder: turns out it was to shim up a machine
05:21 PM Loetmichel: ouch
05:21 PM XXCoder: those isnt regular blocks but calibration blocks. $100 each and certified
05:22 PM Loetmichel: double ouch
05:22 PM Loetmichel: i have a story like that, too
05:22 PM roycroft: and the white house just blocked the cdc from testifying before congress about covid-19 and school reopenings
05:22 PM XXCoder: company had to order new one and certify it lol that block is dead for good
05:22 PM Loetmichel: had a machinist once get a diameter gauge set from the company internal "tool rent"
05:23 PM roycroft: i guess they really mean it when they say they "won't let science get in the way of reopening schools"
05:23 PM andypugh: 75mm / 3” plastic caliper. I have a few of them and they appear to be surprisingly accurate (and read to 0.01mm). https://www.amazon.co.uk/Faithfull-CALDIG75-Digital-Caliper-Capacity/dp/B016QUDZ86
05:23 PM roycroft: grr
05:23 PM roycroft: it's the weekend and i was getting happy until i just read that
05:23 PM Loetmichel: he brought them back a week later, took one out of the box and shouted "those damn things are garbage, none fit!" and threw it with lots of force in a corner.
05:23 PM XXCoder: andy wow cheap too bad cant use em at work lol
05:23 PM roycroft: NEW RULE: no reading news sites right after work on a friday
05:23 PM Loetmichel: the face of the "tool rental clerk"...
05:24 PM Loetmichel: turned out he turned a replacement for one of the gauges on the lathe, even knurled it and threw THAT in the corner as a prank.
05:24 PM roycroft: andypugh: i've found most cheap digital calipers to be fairly accurate
05:24 PM roycroft: they're just not durable
05:24 PM XXCoder: loet lol funny
05:24 PM XXCoder: roy not surpised
05:24 PM roycroft: and they have that never shutting off problem
05:25 PM andypugh: Plastic ones win for measring batteries :-)
05:25 PM Loetmichel: andypugh: o once tested our 10 cheap digital ones with gauge blocks
05:25 PM Loetmichel: less than 2/100m deviation
05:25 PM roycroft: if you buy cheap calipers to save money you have to remove the battery every time you finish using them or they will cost you way more than expensive ones
05:25 PM Loetmichel: thats NOT bad for $15 or so
05:25 PM Loetmichel: mm of course
05:26 PM Tom_L: i use a volt meter for batteries
05:26 PM Loetmichel: yeah, they eat battiers like crazy
05:26 PM * roycroft notes that he's had his mitutoyo calipers for a couple years now or more, and is still on the first battery
05:26 PM Loetmichel: but a 10-slip of AG13 is just a couple bucks, so who cares?
05:26 PM andypugh: The ones I linked, a few years old now batteries all good.
05:26 PM roycroft: with batteries costing $4, if you go through a couple batteries/week your "cheap" calipers are outrageously expensive
05:27 PM roycroft: that's unusual, andypugh
05:27 PM andypugh: That’s why I mentioned it.
05:27 PM Loetmichel: roycroft: a TENPACK of AG13 cost around $2 here
05:27 PM Loetmichel: and its more like one battery a month
05:27 PM Loetmichel: not a weel
05:27 PM roycroft: $30.26 each
05:28 PM roycroft: not as cheap as the harbor freight ones
05:28 PM roycroft: but not expensive
05:28 PM roycroft: 3 or more are $21.55 each
05:28 PM roycroft: 24 or more are $17.62 each
05:28 PM roycroft: good for a group buy
05:29 PM roycroft: i put them on my shop tools list
05:29 PM roycroft: i don't like taking expensive calipers with me when i go to a hardware store
05:30 PM roycroft: and i absolutely need calipers at the hardware store when i'm purchasing fasteners out of the bins
05:30 PM roycroft: people toss them back in randomly
05:30 PM roycroft: so i always take calipers with me and sometimes a thread gauge
05:32 PM Loetmichel: roycroft: over here in germany that could be "bad". i know of some home improvement store chains here that would accuse you of trying to steal said caliper. regardless if your model is not on their stock
05:33 PM Loetmichel: been there had that. took a while to convince them that they only sell garbage and no mitutoyo
05:33 PM Tom_L: most of the ones i go to have a 'test' nut and bolt display to fit your selection to
05:37 PM roycroft: the one i go to the most replaced theis with plastic one that are all beaten up
05:38 PM roycroft: loetmichel: if i feared that i'd engrave an owners mark on the tool prior to entering the store
05:38 PM roycroft: that + the recorded serial number i have at home should be enough to make it clear that i did not steal them from that store
05:39 PM roycroft: tom_l: i have a nice size/thread checker at home - nicer than what is in the hardware store
05:39 PM roycroft: it's faster to use than a caliper and thread gauge
05:39 PM roycroft: i have it mounted right by my fastener storage
05:40 PM Loetmichel: roycroft: i got there eventually
05:40 PM roycroft: but mine is metal, not plastic
05:40 PM Loetmichel: just was quite the ride
05:40 PM roycroft: and i take care of my stuff
05:40 PM roycroft: i should head out to the shop
05:41 PM roycroft: i need a file with a couple safe faces, and i found that they're expensive around here
05:41 PM roycroft: so i bought a regular mill bastard with 4 cutting sides
05:41 PM roycroft: and need to grind the teeth off two sides before i can start my work
06:49 PM robotustra: good time of the day
07:05 PM robotustra: how is everything?
07:31 PM veegee: Just when I thought it was over, the Americans invented a new unit: https://www.amazon.ca/AIRCAT-803-RW-Power-Ratchet-Wrench/dp/B00U11M5LU
07:31 PM veegee: What's a "flub"?
07:35 PM robotustra: what is this wrench for?
07:35 PM robotustra: general purpose wrench?
07:37 PM W1N9Zr0: flubs sounds like something related to making plumbuses
07:43 PM veegee: I'm just looking for a general purpose air ratchet that impacts
07:43 PM veegee: doesn't need super high torque
07:43 PM veegee: Is "reactionless" the same as "impacting"?
07:44 PM veegee: I've never used a reactionless air ratchet before
07:45 PM veegee: But I definitely want at least a light impacting mechanism just to loosen nuts. Not big lug nuts you'd use a 1/2" real air impact for, just anything less than that
07:47 PM Tom_L: get a butterfly impact
07:48 PM Tom_L: https://www.northerntool.com/shop/tools/product_153867_153867
07:50 PM Tom_L: maybe the reactionless is more like a ratchet but air powered
07:50 PM Tom_L: i had one but never called it that
07:51 PM roycroft: i have a couple air ratches that are not impact
07:51 PM robotustra: Tom_L, how is you mill
07:52 PM roycroft: they are slower than molasses in the yukon in december
07:52 PM veegee: Tom_L <3 you read my mind and gave me what I needed but couldn't describe
07:52 PM Tom_L: yeah but they get in places a regular impact can't
07:52 PM veegee: Didn't even know that kind of thing existed
07:52 PM veegee: perfect
07:52 PM Tom_L: oh the butterfly ones?
07:53 PM veegee: the one you linked
07:53 PM Tom_L: they're pretty handy
07:53 PM roycroft: a butterfly impact tool like that with the torque dialed way down is nice
07:53 PM Tom_L: and more torque i think than the ratchet type
07:53 PM veegee: yeah I just need low torque
07:53 PM robotustra: veegee, to fix grinder wheels?
07:53 PM veegee: For the purpose of quickly assembling bolts until contact is made but not too tight since I'll go over them with a torque wrench
07:54 PM veegee: robotustra not for any particular thing, just for hobby shop usage
07:54 PM roycroft: you said "quickly"
07:54 PM roycroft: so you don't want an air ratchet
07:54 PM Tom_L: 175 ft/lb is more than just snug
07:54 PM roycroft: you want an impact wrench with a low torque setting
07:54 PM veegee: the one Tom_L linked shows 8,000 RPM free speed
07:54 PM veegee: also 300 RPM is still fast. Way faster than by hand, no?
07:54 PM Tom_L: but most of those have a 'screw' on the back to dial it down
07:55 PM roycroft: and it's an impact wrench, not a ratchet
07:55 PM veegee: yeah I'm going to get that one because I also want that
07:55 PM veegee: but still looking for a reactionless air ratchet
07:56 PM veegee: Something like this: https://www.youtube.com/watch?v=-xZ_mVVtqb0
07:57 PM roycroft: i have impact wrenches going up to 1" drive/1500ft-lbs, and none of them twist at all when i use them
07:57 PM Tom_L: those are slower by far
07:57 PM robotustra: I would use usual electrical screwdriver
07:58 PM roycroft: my battery drills are a different story
07:58 PM roycroft: but even my battery impact wrenches do not twist
07:58 PM robotustra: because for air - you need an aircompressor
07:58 PM Tom_L: robotustra, he's got plenty of that
07:58 PM veegee: like too much
07:58 PM roycroft: often times it's pretty hot though :P
07:59 PM veegee: 11kW compressor, 360 gallon tank
07:59 PM veegee: But yeah specifically I'm looking for the "ratchet" form factor
07:59 PM Tom_L: there are plenty out there
07:59 PM roycroft: the butterfly ones are great for assembly
07:59 PM veegee: yeah getting that butterfly one for sure
08:00 PM roycroft: the gun-shaped ones are best for disassembly, imo
08:00 PM veegee: I have those already
08:00 PM robotustra: :) I have small one but I don't use it at all - too laud
08:00 PM Tom_L: the ratchet type are somewhat cumbersome
08:00 PM Tom_L: especially with a hose off the end
08:00 PM veegee: It's hard to get into tight spaces with a 1/2" gun form factor impact
08:00 PM roycroft: you put a flex coupler on the end
08:00 PM veegee: the ratchet form factor fits anywhere
08:00 PM roycroft: and use a small pigtail hose
08:01 PM Tom_L: i know
08:01 PM roycroft: you don't need a thick 1/2" air hose going right up to the ratchet when you're just doing assembly work
08:01 PM robotustra: what do you assemble?
08:01 PM Tom_L: i use coiled hose for hand tools
08:01 PM veegee: robotustra this is just for general purpose, I don't do anything specific in my life
08:01 PM roycroft: he assembles collections of tools
08:01 PM veegee: robotustra I have a hobby shop
08:02 PM veegee: LOL but yes
08:02 PM Tom_L: i'm beginning to believe that
08:02 PM veegee: I do indeed have quite a collection
08:02 PM veegee: I appreciate a well made machine
08:02 PM robotustra: :)
08:02 PM veegee: I never buy crap
08:02 PM robotustra: veegee, hackerspace or what?
08:02 PM robotustra: everyone buy crap
08:02 PM veegee: electrical engineering, machining, metalworking
08:03 PM veegee: I have EE lab equipment like high end oscilloscopes, bench multimeters, arbitrary waveform generators
08:03 PM robotustra: I bought a crap manual mill :)
08:03 PM Tom_L: robotustra, he may as well open one :)
08:03 PM veegee: a very good TIG/stick welder, plasma cutter
08:03 PM veegee: a 2500 lb vertical mill, a 14x40 lathe
08:03 PM Tom_L: veegee, what are you gonna build with all this?
08:03 PM robotustra: good, I can't put much in one room :)
08:04 PM robotustra: build a collecton of tools
08:04 PM veegee: I have a document full of projects that I've been appending to over the years. I've only very recently been able to rent this shop
08:04 PM veegee: I own a software engineering company and do that stuff by day. It was a lot of work for many years and very low pay
08:04 PM Tom_L: what's your first project gonna be?
08:04 PM veegee: with mom bringing food
08:05 PM veegee: but it worked out and now I have time for hobbies
08:05 PM veegee: Well just yesterday I fully disassembled the rear end of my BMW RNine-T and removed the crappy stock shock and put in an ohlins shock
08:05 PM robotustra: cool
08:05 PM veegee: night and day difference in handling
08:06 PM veegee: My 13 year old Jeep JK Sahara is going to get a lot of upgrades
08:06 PM Tom_L: :)
08:06 PM robotustra: but why do you need so big lathe for that? :)
08:07 PM Tom_L: robotustra, how _is_ your lathe coming along?
08:07 PM veegee: well not for that, but I have plenty more stuff in the list that does require a lathe
08:07 PM robotustra: Tom_L, slowly but surely
08:07 PM veegee: Also I just love to learn things and be creative and constructive
08:08 PM veegee: And almost always buy used equipment for a much lower price
08:08 PM veegee: I got my 11kW compressor and tank for like $1,000. Retail price is $4,000+
08:08 PM robotustra: Tom_L, https://i.imgur.com/JfaIeJU.jpg
08:08 PM Tom_L: oh wow, you're making progress from the last time i asked
08:09 PM robotustra: https://i.imgur.com/3m8YVPr.jpg
08:09 PM veegee: CNC lathe? nice
08:09 PM robotustra: tomorrow I'll get KC-25 milling machine
08:09 PM robotustra: it's equivalent to grizzly 0704
08:09 PM Tom_L: you spent months scraping on some metal. i was beginning to wonder
08:10 PM robotustra: I decided not to use steel for spindle housing
08:10 PM robotustra: Aluminum I can mill on my router, but not steel
08:11 PM robotustra: I needed to sit bearings in a housing
08:12 PM robotustra: I need to bolt this thing together and ... still too many small things to do
08:13 PM robotustra: I have time on vacations mailny
08:13 PM robotustra: mainly*
08:13 PM Tom_L: right i remember you telling me that
08:14 PM robotustra: veegee, yes, trying to do some small cnc machines
08:14 PM robotustra: the only problem - I can't make chuck plate
08:14 PM veegee: robotustra NOOOOO don't get that
08:14 PM robotustra: or base plate
08:15 PM veegee: Z axis rigidity may be a problem
08:15 PM veegee: Knee mill is far better if you can
08:15 PM robotustra: what is knee mill?
08:15 PM veegee: I considered all these options before buying my Bridgeport clone
08:15 PM veegee: the knee is the Z axis on a bridgeport
08:15 PM robotustra: I live in appartment :)
08:15 PM veegee: instead of the head moving up and down for Z axis control
08:15 PM veegee: oh ok enough said
08:15 PM Tom_L: heh
08:16 PM robotustra: I can't put bridgeport in my room :)
08:16 PM Tom_L: it would end up in the basement
08:16 PM veegee: If you can even get it into a basement
08:16 PM robotustra: definetly
08:16 PM veegee: You'd have to disassemble it. Those weigh like 2,500 lbs
08:16 PM robotustra: KC-25 is only 150 kg
08:16 PM robotustra: 300 lbs
08:16 PM veegee: yeah
08:17 PM robotustra: I can handle it on a dolly
08:19 PM veegee: Get a good vise to go with that
08:20 PM robotustra: I have some small 3" vise
08:20 PM veegee: not a shitty drill press vise
08:20 PM veegee: a positive lock machinists vise
08:20 PM robotustra: I have precise ones
08:20 PM veegee: Similar to this: https://www.amazon.ca/HHIP-3900-2104-Positive-Milling-Opening/dp/B00E0ND9N8
08:22 PM robotustra: I usually clamp parts to the table
08:22 PM robotustra: with t-nuts and bolts
08:22 PM veegee: ah ok
08:23 PM roycroft: i have a 4" vise on my mini mill
08:23 PM roycroft: i keep it parked towards the right side of the table
08:23 PM roycroft: i hold most parts in that
08:23 PM robotustra: I cansern only that the mill has plastic gears in the gearbox
08:23 PM roycroft: and the left half of the table is clear for when i need to mount parts directly on the table
08:24 PM roycroft: and the vise can always be removed of course
08:24 PM roycroft: it only takes a minute to tram it in when it's reinstalled
08:24 PM Tom_L: https://www.shars.com/4-440v-cnc-milling-machine-vise-0-0004-1
08:26 PM robotustra: Tom_L, this one is too expensive
08:27 PM Tom_L: it's a decent vise if you can't afford a kurt
08:28 PM robotustra: https://www.accusizetools.com/precision-screwless-vises/
08:28 PM robotustra: I got this one but 3"
08:28 PM Tom_L: i hate those
08:28 PM Tom_L: i got one in a drawer
08:28 PM robotustra: bad clamp?
08:28 PM Tom_L: inconvenient
08:29 PM veegee: LOL I have one too and hate for the same reason
08:29 PM veegee: The machinist from whom I bought the mill gave me a big version of those
08:29 PM veegee: He just threw it in for free
08:29 PM veegee: He probably hates it too lol
08:29 PM Tom_L: i bet he did
08:29 PM veegee: It's very big and heavy and no doubt its precise and built well. But yeah super annoying
08:30 PM robotustra: it's mainly for toolmaking
08:30 PM robotustra: if you want to put something in a grinder
08:30 PM robotustra: as soon as I make small things I don't suffer much
08:31 PM robotustra: one of the reason why I got them - they fit in my router for clearence
08:31 PM veegee: It's more the style of vise. There are equally small ones with better mechanisms
08:32 PM veegee: But hey whatever works for you
08:32 PM robotustra: my router has about 4" gap between table and portal
08:32 PM Tom_L: robotustra, i made these for my kid: http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube/Cube_small2.jpg
08:33 PM robotustra: cool
08:33 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube/Turners_cube2.jpg
08:33 PM Tom_L: he was supposed to finish that at vo'tech but covid cancelled that so i finished that for him too
08:33 PM veegee: I remember it was funny because he kept reminding me "don't forget to take the vise"
08:34 PM Tom_L: haha
08:34 PM robotustra: btw I probably buy big vise anyway, as soon as the clearence on the new mill will be 8"
08:35 PM Tom_L: i'd make it more if you can
08:36 PM robotustra: the only limit is the concret in a floor
08:37 PM robotustra: I hope my floor will survive
08:37 PM robotustra: and I'll not fall into the basement
08:37 PM robotustra: with all my cnc machines
08:38 PM Tom_L: spread em out a bit
08:38 PM Tom_L: what do your neighbors say?
08:39 PM robotustra: nothing
08:39 PM robotustra: my router is in a soundproof box
08:39 PM Tom_L: ahh
08:40 PM robotustra: I almost don't hear it iven when I'm sitting in the room
08:40 PM Tom_L: that can be good or bad. i listen to mine to see how it's cutting
08:41 PM robotustra: https://www.youtube.com/watch?v=BwhQ6ab06e0
08:42 PM Tom_L: i have no sound on this pc
08:42 PM robotustra: ah, bad
08:42 PM Tom_L: looks like a nice setup
08:43 PM robotustra: so it's about 4 times quiter
08:44 PM Tom_L: i had my sherline in a box
08:44 PM Tom_L: wasn't doubled up or insulated like that though
08:46 PM robotustra: yeah, any mill need an "environment"
08:46 PM Tom_L: does it run hot?
08:46 PM robotustra: no
08:46 PM robotustra: it's a water cooled spindle
08:47 PM Tom_L: is that you in the making of the box?
08:47 PM robotustra: I did this box
08:48 PM robotustra: 5/8" plywood
08:48 PM Tom_L: https://www.youtube.com/watch?v=Yxa8HH3t_Ds
08:48 PM robotustra: and black rubber for car doors
08:48 PM Tom_L: that one came on after yours
08:48 PM Tom_L: that's not you
08:49 PM robotustra: not me
08:49 PM robotustra: my youtube channel is robotustra
08:50 PM Tom_L: yeah i wasn't paying attention
08:51 PM robotustra: my router is sitting on 4 inner tubes - it's floating, so, no low frequency vibration pass to the floor
08:51 PM robotustra: and rubber cuts high frequencies
08:52 PM Tom_L: yeah
08:54 PM robotustra: something similar I have to make for cnc lathe and for manual mill, and may be upgrade it with the time, I'll see
08:54 PM robotustra: now I decided to learn a bit more about linuxcnc
08:56 PM robotustra: trying to understand how to connect gui to the engine
09:04 PM Tom_L: ?
09:04 PM Tom_L: which gui are you looking at?
09:05 PM robotustra: my own
09:05 PM Tom_L: qtpyvcp?
09:05 PM robotustra: no
09:05 PM Tom_L: have you looked at that?
09:05 PM robotustra: no
09:06 PM Tom_L: you _can_ build your own with it probably alot easier
09:06 PM robotustra: can you give me a link?
09:06 PM Tom_L: join #hazzy
09:07 PM robotustra: it's done in python
09:07 PM Tom_L: yeah
09:07 PM robotustra: I don't know python
09:08 PM Tom_L: you really don't need to
09:08 PM Tom_L: https://www.qtpyvcp.com/
09:08 PM hazzy-m: robotustra: www.qtpyvcp.com
09:08 PM robotustra: https://i.imgur.com/srombUk.png
09:08 PM robotustra: this is gui I'm working on
09:08 PM Tom_L: yeah you can do that with qtpyvcp and the hooks are probably alot easier
09:09 PM robotustra: probably
09:09 PM Tom_L: https://pypi.org/project/probe-basic/
09:10 PM Tom_L: that's one they've been working on for ages
09:10 PM Tom_L: i think it demonstrates most of the possibilities of it
09:11 PM Tom_L: https://github.com/kcjengr/probe_basic
09:12 PM Tom_L: https://www.youtube.com/watch?v=Y4OaXS05ZMQ
09:13 PM Tom_L: https://www.youtube.com/watch?v=ryp-dghwCzs
09:15 PM robotustra: kurt cloned my qtlcnc repo and I think he took some ideas from it
09:15 PM robotustra: may be
09:15 PM robotustra: like building controls from config file
09:16 PM robotustra: I did mine and qt and c++
09:16 PM Tom_L: huh
09:16 PM robotustra: and I build all gui from text file configuration
09:17 PM robotustra: it means all controls and actions are written in a text file, you don't need to recompile anything to change gui :)
09:17 PM Tom_L: support for qt may be limited in the future
09:18 PM Tom_L: i don't know alot about any of them
09:18 PM robotustra: may be, that's why I want to go away from qt
09:18 PM robotustra: just use pure opengl, glut
09:18 PM robotustra: and barebone gui building
09:22 PM skunkworks: Just bought a 9.99 quad copter on a whim.. I think I just spent the last hour flying it around. Amazing.
09:22 PM robotustra: so qtpyvcp is a constructor of GUI
09:23 PM roycroft: i was just pondering building a quad drone
09:23 PM roycroft: it seems like it would be fun to fly
09:23 PM roycroft: and fun to build
09:25 PM robotustra: did anybody make a decent looking GUI in qtpyvcp?
09:26 PM robotustra: yeah, my friend is a fun of copters, has built like 9 of them
09:27 PM Tom_L: robotustra, talk to JT-Cave about some he's done
09:28 PM hazzy-m: robotustra: decent looking depends on personal taste, I no a lot of people would not like your GUI, but I think its perfect, clean and simple
09:29 PM hazzy-m: did you make any progress with the gcode backplot?
09:30 PM hazzy-m: I think that's what you were working on last we talked
09:31 PM * hazzy-m uploaded an image: Screenshot from 2020-06-21 23-13-39.png (34KB) < https://matrix.org/_matrix/media/r0/download/matrix.org/rgZpsHuJswSGkiSotyCpCKNn >
09:31 PM hazzy-m: these are the DROs on my QyPyVCP based GUI
09:32 PM hazzy-m: the HALBarIndicators can be used to display individual axis load or following error
09:34 PM robotustra: Last time I made openGL view, and stoppen at it. To get the trajectory I need to do parsing of g-code with rf274 to canonical form and after that extract the path data
09:35 PM robotustra: so I abandoned it to the better times
09:35 PM skunkworks: hazzy-m: i cant wait to find time to play with your stuff
09:35 PM robotustra: I still don't know how linixcncn works inside.
09:35 PM robotustra: have to fix it
09:37 PM robotustra: hazzy-m, looks good but I would make numbers more contrast, may be to the level of letters XYZ
09:37 PM hazzy-m: robotustra: well I'm looking forward to your GUI kit being finished, or at least more complete, you have some really interesting ideas
09:38 PM robotustra: hope I'll find time to it
09:38 PM hazzy-m: robotustra: that can all be changed in the GUI specific style sheet, that's just the default color and font
09:38 PM robotustra: my vacations are over, but thanks god it's still summer, long days,
09:39 PM robotustra: and remote work also helps to save 1 hour for travel
09:39 PM hazzy-m: skunkworks: I can't wait to have time to play with it too :)
09:39 PM robotustra: skunkworks, are you working in skunkworks?
09:44 PM skunkworks: no. nick name.. long story
09:46 PM robotustra: skunkworks is a airspace company
09:47 PM skunkworks: well.. a secret arm of an airspace company
09:47 PM CaptHindsight: https://ibin.co/2yEz1zoUZ5jZ.jpg hows this for a gui? for fans of reprap
09:48 PM robotustra: I see tha axis gui + vcp
09:48 PM CaptHindsight: with pronterface of whatever that crap is called
09:48 PM CaptHindsight: printrun
09:49 PM robotustra: sounds like joke :)
09:50 PM CaptHindsight: looks like joke too
09:50 PM robotustra: Tom_L, now I want to buy that vise
09:50 PM Tom_L: haha
09:51 PM hazzy-m: CaptHindsight: lol
09:51 PM robotustra: but first thing first, build an enclosure
09:54 PM skunkworks: CaptHindsight: where is the image from? it has my k&t side panel
09:56 PM CaptHindsight: skunkworks: yeah, I think i grabbed it the day you had posted it
09:57 PM CaptHindsight: some cut n paste from repcrap and wallah!!
09:57 PM skunkworks: ah! i thought you found some random image on the net
09:58 PM CaptHindsight: I can make it worse, maybe when I have tome :)
10:01 PM hazzy-m: CaptHindsight: spare our eyes :)
10:02 PM robotustra: yes, must wash my eyes
10:05 PM robotustra: where I can find .hal syntax?
10:12 PM Tom_L: http://linuxcnc.org/docs/2.8/html/hal/intro.html
10:12 PM Tom_L: http://linuxcnc.org/docs/2.8/html/hal/basic-hal.html
10:13 PM robotustra: thank you
10:14 PM CaptHindsight: hazzy-m: getting out the fluorescent color pallet
11:17 PM XXCoder: those dum dums try to steal a tv lol https://youtu.be/zdcH25Dn_lo
