[09:21:49] <gregcnc> pink_vampire video if you are going to make that saw cut on that spindle, the destruction should be heard here in chicago
[09:22:37] <gregcnc> you can't feed saws like endmills maybe 1/10-1/20 normal chipload and low RPM, <1000.

[09:28:33] <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?)
[09:31:49] <gregcnc> which photo?
[09:36:50] <gloops> https://www.ebay.co.uk
[09:49:21] <gregcnc> Mute this clip it's loud https://www.instagram.com
[09:50:12] <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?
[09:58:16] <skunkworks> That is cool
[09:59:21] <Tom_L> skunkworks, you got your work cut out now!
[09:59:21] <skunkworks> https://www.youtube.com
[09:59:41] <skunkworks> I give up ;)
[10:01:26] <gregcnc> I guess I should just do the math in the Fanuc manuals to see what's needed
[10:02:56] <gregcnc> this is very fast, but depends on how accurate you need the flats to be, because they aren't
[10:10:26] <perry_j1987> skunkworks that is crazy
[10:41:44] <perry_j1987> eishhhh https://www.youtube.com that part moving all around when they are trying to machine it lol
[10:42:42] <Tom_L> too much gab
[10:44:08] <perry_j1987> was watching to get a peek inside the building
[10:44:14] <perry_j1987> use to drive by it all the time
[10:47:17] <perry_j1987> https://www.youtube.com lol
[10:47:25] <perry_j1987> robot hitting the mouse button cracked me up way too much
[10:48:22] <perry_j1987> looks like making paddle lock parts
[10:48:34] <gregcnc> happens even in "real" shops. close teh door, push the green button

[12:06:54] <perry_j1987> so no tie in with the robotic arm two separate ecosystems eh?
[12:07:45] <perry_j1987> i want to get one of these used kuka robot arms to play with some time
[12:17:09] <gregcnc> depends if the machine supports it

[12:27:58] <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

[12:43:20] <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.
[12:44:49] <Tom_L> is that like suicide?
[12:45:31] <skunkworks> My teenage self thought very deeply about it..
[12:45:38] <Tom_L> heh
[12:46:27] <perry_j1987> lol
[13:01:47] <Dolence> gregcnc got way better results
[13:02:07] <gregcnc> what did you do?
[13:02:15] <Dolence> changed resolution from 32 to 256 steps per mm
[13:02:48] <Dolence> and changed accelleration value
[13:03:14] <Dolence> it was too high, causing problems in corners and when doing briddges
[13:03:44] <Dolence> now I'm using 3200 steps per revolution / 16 microsteps
[13:04:09] <Dolence> It's very nice even on aluminum :D
[13:04:12] <gregcnc> yeah that makes sense
[13:04:36] <Dolence> thank you very much!
[13:05:48] <gregcnc> you're welcome. are tolerances OK?
[13:11:11] <Dolence> Didn't measured yet. I mainly use to cut parts for my own personal use
[13:11:52] <gregcnc> what is the resolution of the encoder on the motors?
[13:12:11] <Dolence> I'm building a large 3D printer (48x48cm useful table area)
[13:12:22] <perry_j1987> https://www.youtube.com fun watching all the parts climb out of the machine on their own
[13:12:24] <Dolence> I guess it's 1000
[13:13:20] <Dolence> Yeah, encoder resolution is 1000
[13:13:25] <Dolence> Is this ok?
[13:13:35] <Tom_L> plenty good yes
[13:13:42] <gregcnc> i'm just curious.

[16:51:56] <veegee> yay my new aircat die grinder arrived but I'm still sitting at the office
[16:52:14] <veegee> Can I blow into the air intake to make it spin? PLEEEEEEASE?
[16:52:29] <veegee> JUST ONCE I PROMIES
[16:53:05] -!- CaptHindsight has joined #linuxcnc
[16:54:04] <Tom_L> likely to void the warranty!
[16:56:55] <veegee> It's the aircat 6260 1hp straight die grinder
[16:56:59] <veegee> Feels nice and solid
[16:57:49] <CaptHindsight> FDM/FFF is so slow, why do people make printers with an area over a few cm^3?
[16:58:35] <CaptHindsight> over that size use SLA/LCD/DLP or SLS with multiple lasers
[17:08:54] <andypugh> It doesn’t matter how long it takes if you can sleep or watch TV at the same time.
[17:10:19] <veegee> Wow making the die grinder spin by blowing into it is quite the exercise for your diaphragm
[17:10:24] -!- infornography has joined #linuxcnc
[17:10:37] <CaptHindsight> I see some that will take days to use up the volume
[17:10:46] <veegee> so much airflow and pressure required

[17:43:21] <XXCoder> ouch yeah
[17:43:25] <XXCoder> I bet its very stiff
[17:45:02] <andypugh> If I used a divider every day, rather than every year, I would be more tempted.
[17:45:40] -!- JavaBean has joined #linuxcnc
[17:51:18] <roycroft> i buy most of my starrett tools one ebay these days
[17:51:29] <roycroft> for usually about 1/4 what they cost new
[17:52:05] <XXCoder> some are fakies
[17:52:10] <XXCoder> expecially mitoyoto
[17:52:27] <XXCoder> fake ones dont actually do power management so it loses power in a month or so
[17:52:42] <XXCoder> while real ones can last year or 2 of usage
[17:53:14] <roycroft> i got a nice 4"/100mm mitutoyo digital caliper off amazon's warehouse site a couple years ago for just over $100
[17:53:25] <roycroft> their "warehouse" is open box/returns stuff
[17:53:39] <XXCoder> 4" pretty small
[17:53:52] <XXCoder> good if you make only small parts I guess
[17:53:53] <roycroft> the caliper i still had the factory shrink wrap on, but the shrink wrap was a bit torn
[17:54:05] <roycroft> i have some 6" ones
[17:54:21] <roycroft> but i find that most of what i measure with calipers is 4" or shorter
[17:54:28] <roycroft> and a 4" one fits in a pocket very nicely
[17:54:32] <XXCoder> nice
[17:54:51] <roycroft> it's a very useful and convenient size
[17:55:13] <roycroft> but it should not be one's only calipers - i'd say if you only had one, get a 6"
[17:56:09] <JavaBean> 6"??? i find my calipers a bit small, kinda want a 12"
[17:56:22] <XXCoder> lot depends on usercase
[17:56:30] <XXCoder> my 6" is all I need
[18:02:50] <roycroft> i think you'll find that 6" is the most common size dial/digital calipers
[18:03:12] <Loetmichel> on that account: i should order a dozen more $20 digital 6" calipers for the company. they tend to evaporate. :-)
[18:04:28] -!- ferdna has quit [Quit: Leaving]
[18:05:00] <roycroft> the only $20 ones i see around here are from harbor freight
[18:05:27] <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
[18:05:49] <roycroft> 2. get full of crud right away and start giving inaccurate readings
[18:05:57] <roycroft> and 3. die an early and horrible death
[18:06:29] <XXCoder> Loetmichel: heavy workshop theft? doesnt sound good
[18:06:31] <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
[18:06:54] <roycroft> so a quality set like the mitutoyo is actually a lot cheaper, even in the short term
[18:07:00] <XXCoder> roy yep they tend to use bad mitoyoto hack that dont do power management
[18:07:02] <roycroft> schook, xxcoder
[18:07:04] <roycroft> school
[18:07:05] <XXCoder> i threw away my old cheap one
[18:07:12] <roycroft> in his case the cheap ones make sense
[18:07:17] <XXCoder> indeed
[18:07:24] <roycroft> because they're going be stolen or damaged right away anyway
[18:07:38] <roycroft> and the cheap ones work ok for a couple weeks
[18:07:47] <roycroft> which is about how long they last in a school
[18:07:57] <XXCoder> my cheap one lasted a year or so
[18:08:05] <XXCoder> I had to reset zero each time I use it though lol
[18:08:10] <roycroft> i have a box of hem
[18:08:11] <XXCoder> it was such a bad one
[18:08:14] <roycroft> i need to get rid of them
[18:08:21] <roycroft> but they're not landfill material
[18:08:24] <XXCoder> turn them into dro thing
[18:08:29] <roycroft> so i just collect them in a box
[18:08:30] <XXCoder> or donate to schools
[18:08:37] <roycroft> they're all dead
[18:08:46] <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.
[18:08:48] <XXCoder> battery dead or just dead
[18:08:53] <roycroft> one of these days i'll remember to take the box with me when i got to recycle electronics
[18:09:02] <roycroft> 3" would be nice
[18:09:18] <roycroft> although i find the 4" to be a really handy size
[18:09:20] <XXCoder> 3" is nice but im maxed out on certified tools at shop so I cant get more
[18:09:32] <Loetmichel> XXCoder: nope.i found one in the coffee kitchen, one on the floor in the measurement chamber and one outside in the rain.
[18:09:44] <roycroft> 3" is even more pocket-size than 4"
[18:09:57] <XXCoder> maybe that guy hoped his caliper would grow in rain? ;)
[18:09:58] <Loetmichel> no theft. just lazy workers that "disapper" them in some remote corners
[18:10:11] <Tom_L> 8" is a fairly handy size
[18:10:17] <Loetmichel> we HAD 10 at one time though
[18:10:20] <roycroft> or maybe they break and the workers hide them
[18:10:27] <Loetmichel> no idea where the rest disappeared
[18:10:52] <roycroft> they go to that island where one sock out of every pair goes
[18:10:59] <Loetmichel> you cant break much on a 12 eur caliper
[18:11:11] <Loetmichel> yes, i think so
[18:11:36] <Loetmichel> ah, and i THINK i have one at home. freshly cleaned in the washing machine ;)
[18:11:48] <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
[18:11:57] <XXCoder> turns out it was to shim up a machine
[18:12:07] <Loetmichel> ouch
[18:12:15] <XXCoder> those isnt regular blocks but calibration blocks. $100 each and certified
[18:12:29] <Loetmichel> double ouch
[18:12:40] <Loetmichel> i have a story like that, too
[18:12:43] <roycroft> and the white house just blocked the cdc from testifying before congress about covid-19 and school reopenings
[18:12:44] <XXCoder> company had to order new one and certify it lol that block is dead for good
[18:13:04] -!- leorat has joined #linuxcnc
[18:13:11] <Loetmichel> had a machinist once get a diameter gauge set from the company internal "tool rent"
[18:13:30] <roycroft> i guess they really mean it when they say they "won't let science get in the way of reopening schools"
[18:13:36] <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
[18:13:40] <roycroft> grr
[18:13:57] <roycroft> it's the weekend and i was getting happy until i just read that
[18:14:00] <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.
[18:14:06] <XXCoder> andy wow cheap too bad cant use em at work lol
[18:14:13] <roycroft> NEW RULE: no reading news sites right after work on a friday
[18:14:17] <Loetmichel> the face of the "tool rental clerk"...
[18:14:54] <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.
[18:15:00] <roycroft> andypugh: i've found most cheap digital calipers to be fairly accurate
[18:15:05] <roycroft> they're just not durable
[18:15:17] <XXCoder> loet lol funny
[18:15:21] <XXCoder> roy not surpised
[18:15:22] <roycroft> and they have that never shutting off problem
[18:15:33] <andypugh> Plastic ones win for measring batteries :-)
[18:15:48] <Loetmichel> andypugh: o once tested our 10 cheap digital ones with gauge blocks
[18:15:59] <Loetmichel> less than 2/100m deviation
[18:16:03] <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
[18:16:12] <Loetmichel> thats NOT bad for $15 or so
[18:16:15] <Loetmichel> mm of course
[18:16:28] <Tom_L> i use a volt meter for batteries
[18:16:33] <Loetmichel> yeah, they eat battiers like crazy
[18:16:36] * roycroft notes that he's had his mitutoyo calipers for a couple years now or more, and is still on the first battery
[18:16:54] <Loetmichel> but a 10-slip of AG13 is just a couple bucks, so who cares?
[18:17:06] <andypugh> The ones I linked, a few years old now batteries all good.
[18:17:10] <roycroft> with batteries costing $4, if you go through a couple batteries/week your "cheap" calipers are outrageously expensive
[18:17:27] <roycroft> that's unusual, andypugh
[18:17:37] <andypugh> That’s why I mentioned it.
[18:18:00] <Loetmichel> roycroft: a TENPACK of AG13 cost around $2 here
[18:18:12] <Loetmichel> and its more like one battery a month
[18:18:15] <Loetmichel> not a weel
[18:18:18] <roycroft> $30.26 each
[18:18:32] <roycroft> not as cheap as the harbor freight ones
[18:18:39] <roycroft> but not expensive
[18:18:54] <roycroft> 3 or more are $21.55 each
[18:19:05] -!- infornography has quit [Quit: Leaving]
[18:19:07] <roycroft> 24 or more are $17.62 each
[18:19:12] <roycroft> good for a group buy
[18:19:43] <roycroft> i put them on my shop tools list
[18:20:14] <roycroft> i don't like taking expensive calipers with me when i go to a hardware store
[18:20:33] <roycroft> and i absolutely need calipers at the hardware store when i'm purchasing fasteners out of the bins
[18:20:41] <roycroft> people toss them back in randomly
[18:20:57] <roycroft> so i always take calipers with me and sometimes a thread gauge
[18:23:01] <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
[18:23:34] <Loetmichel> been there had that. took a while to convince them that they only sell garbage and no mitutoyo
[18:23:47] <Tom_L> most of the ones i go to have a 'test' nut and bolt display to fit your selection to
[18:28:19] <roycroft> the one i go to the most replaced theis with plastic one that are all beaten up
[18:28:54] <roycroft> loetmichel: if i feared that i'd engrave an owners mark on the tool prior to entering the store
[18:29:24] <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
[18:30:00] <roycroft> tom_l: i have a nice size/thread checker at home - nicer than what is in the hardware store
[18:30:11] <roycroft> it's faster to use than a caliper and thread gauge
[18:30:21] <roycroft> i have it mounted right by my fastener storage
[18:30:27] <Loetmichel> roycroft: i got there eventually
[18:30:32] <roycroft> but mine is metal, not plastic
[18:30:34] <Loetmichel> just was quite the ride
[18:30:36] <roycroft> and i take care of my stuff
[18:31:25] <roycroft> i should head out to the shop
[18:31:44] <roycroft> i need a file with a couple safe faces, and i found that they're expensive around here
[18:32:06] <roycroft> so i bought a regular mill bastard with 4 cutting sides
[18:32:21] <roycroft> and need to grind the teeth off two sides before i can start my work

[20:21:57] <veegee> Just when I thought it was over, the Americans invented a new unit: https://www.amazon.ca
[20:22:06] <veegee> What's a "flub"?
[20:25:56] <robotustra> what is this wrench for?
[20:26:15] <robotustra> general purpose wrench?
[20:27:30] <W1N9Zr0> flubs sounds like something related to making plumbuses
[20:33:28] <veegee> I'm just looking for a general purpose air ratchet that impacts
[20:33:41] <veegee> doesn't need super high torque
[20:34:05] <veegee> Is "reactionless" the same as "impacting"?
[20:34:57] <veegee> I've never used a reactionless air ratchet before
[20:36:10] <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
[20:38:12] <Tom_L> get a butterfly impact
[20:39:22] <Tom_L> https://www.northerntool.com
[20:40:27] <Tom_L> maybe the reactionless is more like a ratchet but air powered
[20:40:33] <Tom_L> i had one but never called it that
[20:42:04] <roycroft> i have a couple air ratches that are not impact
[20:42:18] <robotustra> Tom_L, how is you mill
[20:42:40] <roycroft> they are slower than molasses in the yukon in december
[20:42:58] <veegee> Tom_L <3 you read my mind and gave me what I needed but couldn't describe
[20:43:09] <Tom_L> yeah but they get in places a regular impact can't
[20:43:12] <veegee> Didn't even know that kind of thing existed
[20:43:19] <veegee> perfect
[20:43:26] <Tom_L> oh the butterfly ones?
[20:43:30] <veegee> the one you linked
[20:43:34] <Tom_L> they're pretty handy
[20:43:37] <roycroft> a butterfly impact tool like that with the torque dialed way down is nice
[20:43:43] <Tom_L> and more torque i think than the ratchet type
[20:43:47] <veegee> yeah I just need low torque
[20:44:16] <robotustra> veegee, to fix grinder wheels?
[20:44:21] <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
[20:44:34] <veegee> robotustra not for any particular thing, just for hobby shop usage
[20:44:39] <roycroft> you said "quickly"
[20:44:44] <roycroft> so you don't want an air ratchet
[20:44:52] <Tom_L> 175 ft/lb is more than just snug
[20:44:54] <roycroft> you want an impact wrench with a low torque setting
[20:45:05] <veegee> the one Tom_L linked shows 8,000 RPM free speed
[20:45:18] <veegee> also 300 RPM is still fast. Way faster than by hand, no?
[20:45:18] <Tom_L> but most of those have a 'screw' on the back to dial it down
[20:45:27] <roycroft> and it's an impact wrench, not a ratchet
[20:45:52] <veegee> yeah I'm going to get that one because I also want that
[20:45:59] <veegee> but still looking for a reactionless air ratchet
[20:46:27] <veegee> Something like this: https://www.youtube.com
[20:48:17] <roycroft> i have impact wrenches going up to 1" drive/1500ft-lbs, and none of them twist at all when i use them
[20:48:18] <Tom_L> those are slower by far
[20:48:22] <robotustra> I would use usual electrical screwdriver
[20:48:38] <roycroft> my battery drills are a different story
[20:48:48] <roycroft> but even my battery impact wrenches do not twist
[20:48:50] <robotustra> because for air - you need an aircompressor
[20:49:06] <Tom_L> robotustra, he's got plenty of that
[20:49:17] <veegee> like too much
[20:49:17] <roycroft> often times it's pretty hot though :P
[20:49:39] <veegee> 11kW compressor, 360 gallon tank
[20:49:59] <veegee> But yeah specifically I'm looking for the "ratchet" form factor
[20:50:12] <Tom_L> there are plenty out there
[20:50:17] <roycroft> the butterfly ones are great for assembly
[20:50:25] <veegee> yeah getting that butterfly one for sure
[20:50:31] <roycroft> the gun-shaped ones are best for disassembly, imo
[20:50:39] <veegee> I have those already
[20:50:40] <robotustra> :) I have small one but I don't use it at all - too laud
[20:50:41] <Tom_L> the ratchet type are somewhat cumbersome
[20:50:48] <Tom_L> especially with a hose off the end
[20:50:59] -!- MrHindsight has quit [Ping timeout: 240 seconds]
[20:51:03] <veegee> It's hard to get into tight spaces with a 1/2" gun form factor impact
[20:51:11] <roycroft> you put a flex coupler on the end
[20:51:18] <veegee> the ratchet form factor fits anywhere
[20:51:20] <roycroft> and use a small pigtail hose
[20:51:28] <Tom_L> i know
[20:51:36] <roycroft> you don't need a thick 1/2" air hose going right up to the ratchet when you're just doing assembly work
[20:51:37] <robotustra> what do you assemble?
[20:51:54] <Tom_L> i use coiled hose for hand tools
[20:51:57] <veegee> robotustra this is just for general purpose, I don't do anything specific in my life
[20:52:21] <roycroft> he assembles collections of tools
[20:52:26] <veegee> robotustra I have a hobby shop
[20:52:28] <veegee> LOL but yes
[20:52:31] <Tom_L> i'm beginning to believe that
[20:52:37] <veegee> I do indeed have quite a collection

[20:53:50] <veegee> a very good TIG/stick welder, plasma cutter
[20:53:58] <veegee> a 2500 lb vertical mill, a 14x40 lathe
[20:54:11] <Tom_L> veegee, what are you gonna build with all this?
[20:54:18] <robotustra> good, I can't put much in one room :)
[20:54:43] <robotustra> build a collecton of tools
[20:54:44] <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
[20:55:08] <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
[20:55:12] <Tom_L> what's your first project gonna be?
[20:55:17] <veegee> with mom bringing food
[20:55:29] <veegee> but it worked out and now I have time for hobbies
[20:55:57] <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

[20:59:50] <veegee> CNC lathe? nice
[21:00:06] <robotustra> tomorrow I'll get KC-25 milling machine
[21:00:17] <robotustra> it's equivalent to grizzly 0704
[21:00:18] <Tom_L> you spent months scraping on some metal. i was beginning to wonder
[21:01:08] <robotustra> I decided not to use steel for spindle housing
[21:01:24] <robotustra> Aluminum I can mill on my router, but not steel
[21:01:41] <robotustra> I needed to sit bearings in a housing
[21:02:45] <robotustra> I need to bolt this thing together and ... still too many small things to do
[21:03:59] <robotustra> I have time on vacations mailny
[21:04:10] <robotustra> mainly*
[21:04:23] <Tom_L> right i remember you telling me that
[21:04:41] <robotustra> veegee, yes, trying to do some small cnc machines
[21:05:15] <robotustra> the only problem - I can't make chuck plate
[21:05:18] <veegee> robotustra NOOOOO don't get that
[21:05:21] <robotustra> or base plate
[21:05:28] <veegee> Z axis rigidity may be a problem
[21:05:38] <veegee> Knee mill is far better if you can
[21:05:59] <robotustra> what is knee mill?
[21:06:01] <veegee> I considered all these options before buying my Bridgeport clone
[21:06:10] <veegee> the knee is the Z axis on a bridgeport
[21:06:16] <robotustra> I live in appartment :)
[21:06:18] <veegee> instead of the head moving up and down for Z axis control
[21:06:22] <veegee> oh ok enough said
[21:06:26] <Tom_L> heh
[21:06:28] <robotustra> I can't put bridgeport in my room :)
[21:06:33] <Tom_L> it would end up in the basement
[21:06:41] <veegee> If you can even get it into a basement
[21:06:41] <robotustra> definetly
[21:06:50] <veegee> You'd have to disassemble it. Those weigh like 2,500 lbs
[21:07:07] <robotustra> KC-25 is only 150 kg
[21:07:12] <robotustra> 300 lbs
[21:07:20] <veegee> yeah
[21:07:43] <robotustra> I can handle it on a dolly
[21:09:55] <veegee> Get a good vise to go with that
[21:10:45] <robotustra> I have some small 3" vise
[21:10:57] <veegee> not a shitty drill press vise
[21:11:08] <veegee> a positive lock machinists vise
[21:11:20] <robotustra> I have precise ones

[21:13:23] <veegee> ah ok
[21:13:41] <roycroft> i have a 4" vise on my mini mill
[21:13:51] <roycroft> i keep it parked towards the right side of the table
[21:13:57] <roycroft> i hold most parts in that
[21:14:09] <robotustra> I cansern only that the mill has plastic gears in the gearbox
[21:14:15] <roycroft> and the left half of the table is clear for when i need to mount parts directly on the table
[21:14:27] <roycroft> and the vise can always be removed of course
[21:14:45] <roycroft> it only takes a minute to tram it in when it's reinstalled
[21:15:26] <Tom_L> https://www.shars.com
[21:16:45] <robotustra> Tom_L, this one is too expensive
[21:17:49] <Tom_L> it's a decent vise if you can't afford a kurt
[21:18:39] <robotustra> https://www.accusizetools.com
[21:18:47] <robotustra> I got this one but 3"
[21:18:57] <Tom_L> i hate those
[21:19:03] <Tom_L> i got one in a drawer
[21:19:11] <robotustra> bad clamp?
[21:19:20] <Tom_L> inconvenient
[21:19:27] <veegee> LOL I have one too and hate for the same reason
[21:19:39] <veegee> The machinist from whom I bought the mill gave me a big version of those
[21:19:44] <veegee> He just threw it in for free
[21:19:49] <veegee> He probably hates it too lol
[21:19:50] <Tom_L> i bet he did
[21:20:10] <veegee> It's very big and heavy and no doubt its precise and built well. But yeah super annoying

[21:21:19] <robotustra> as soon as I make small things I don't suffer much
[21:21:59] <robotustra> one of the reason why I got them - they fit in my router for clearence
[21:22:25] <veegee> It's more the style of vise. There are equally small ones with better mechanisms
[21:22:38] <veegee> But hey whatever works for you
[21:23:13] <robotustra> my router has about 4" gap between table and portal

[21:24:29] <Tom_L> haha
[21:25:26] <robotustra> btw I probably buy big vise anyway, as soon as the clearence on the new mill will be 8"
[21:25:53] <Tom_L> i'd make it more if you can

[22:14:02] <roycroft> i was just pondering building a quad drone
[22:14:08] <roycroft> it seems like it would be fun to fly
[22:14:16] <roycroft> and fun to build
[22:15:56] <robotustra> did anybody make a decent looking GUI in qtpyvcp?
[22:16:42] <robotustra> yeah, my friend is a fun of copters, has built like 9 of them
[22:17:38] <Tom_L> robotustra, talk to JT-Cave about some he's done
[22:19:10] <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
[22:19:38] <hazzy-m> did you make any progress with the gcode backplot?
[22:20:52] <hazzy-m> I think that's what you were working on last we talked
[22:21:55] * hazzy-m uploaded an image: Screenshot from 2020-06-21 23-13-39.png (34KB) < https://matrix.org >
[22:22:23] <hazzy-m> these are the DROs on my QyPyVCP based GUI
[22:23:06] <hazzy-m> the HALBarIndicators can be used to display individual axis load or following error
[22:25:20] <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
[22:25:37] <robotustra> so I abandoned it to the better times
[22:25:37] <skunkworks> hazzy-m: i cant wait to find time to play with your stuff
[22:26:16] <robotustra> I still don't know how linixcncn works inside.
[22:26:22] <robotustra> have to fix it
[22:28:00] <robotustra> hazzy-m, looks good but I would make numbers more contrast, may be to the level of letters XYZ
[22:28:09] <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
[22:28:35] <robotustra> hope I'll find time to it
[22:29:03] <hazzy-m> robotustra: that can all be changed in the GUI specific style sheet, that's just the default color and font
[22:29:08] <robotustra> my vacations are over, but thanks god it's still summer, long days,
[22:29:43] <robotustra> and remote work also helps to save 1 hour for travel
[22:30:02] <hazzy-m> skunkworks: I can't wait to have time to play with it too :)
[22:30:23] <robotustra> skunkworks, are you working in skunkworks?
[22:35:08] <skunkworks> no. nick name.. long story
[22:36:56] <robotustra> skunkworks is a airspace company
[22:37:29] <skunkworks> well.. a secret arm of an airspace company
[22:37:43] <CaptHindsight> https://ibin.co hows this for a gui? for fans of reprap
[22:38:41] <robotustra> I see tha axis gui + vcp

[22:40:38] <CaptHindsight> looks like joke too
[22:40:54] <robotustra> Tom_L, now I want to buy that vise
[22:41:09] <Tom_L> haha
[22:41:30] <hazzy-m> CaptHindsight: lol
[22:41:58] <robotustra> but first thing first, build an enclosure
[22:45:26] <skunkworks> CaptHindsight: where is the image from? it has my k&t side panel
[22:47:07] <CaptHindsight> skunkworks: yeah, I think i grabbed it the day you had posted it
[22:47:32] <CaptHindsight> some cut n paste from repcrap and wallah!!
[22:47:56] <skunkworks> ah! i thought you found some random image on the net
[22:48:36] <CaptHindsight> I can make it worse, maybe when I have tome :)
