01:52 AM gloops: any progress with the mill miss0r?
01:55 AM XXCoder: hey miss0r
01:55 AM miss0r: gloops: I have it stripped down and somewhat wiped off. i'm not going to do much more before the technician gets here in about 1.5 hours
01:55 AM miss0r: hey XXCoder
01:55 AM XXCoder: my cnc router is in my closet :( no room at all to run for while yet
01:55 AM XXCoder: we are planning to build a shop
01:55 AM miss0r: XXCoder: remember to build a well insulated shop :)
01:55 AM XXCoder: indeed
01:55 AM XXCoder: for winter is coming :P
01:55 AM miss0r: indeed
01:56 AM miss0r: I'm just not shure where I can get plate shim-stock around here
01:59 AM gloops: by shim you mean a plate that is going to be in contact with the rail?
01:59 AM Deejay: moin
02:00 AM miss0r: Yeah. The gip is bottomed out, and I can still force around 0.015mm of play with the ram extented completely
02:00 AM miss0r: heh. This is actualy sad. The only CNC I have in complete working order at the moment, is actualy my X-Carve... I'm having some nasty driver issues with my Camm-3. Like random errors. Sometimes it works, then after a PC power cycle it doesn't.
02:00 AM XXCoder: weird
02:02 AM miss0r: it all happened when I went from a 32bit pc running windows xp 32bit to a 64bit pc running windows xp 32bit. That messed it up. I need to go back.
02:02 AM XXCoder: but not stright up 64 bit?
02:02 AM gloops: amazing how time passes messing about with stuff like that
02:03 AM miss0r: XXCoder: nope. The drivers for this thing is _OLD_. and theres no way to install in on anything newer. maybe using XP is a bit of a stretch. (From what I read on forums).
02:04 AM XXCoder: x-carve is that okd?
02:04 AM XXCoder: oh camm-3 nm
02:04 AM miss0r: yeah ;) sadly the X-carve works as well as the factory intented it to
02:04 AM miss0r: well, I did some minor upgrades so it is somewhat useable...
02:04 AM XXCoder: alum milling?
02:07 AM miss0r: XXCoder: I'm sure it could do some alu milling. but the result would be nasty i'm sure. unless you took it ridiculous slow
02:07 AM XXCoder: likely
02:07 AM miss0r: its for wood, no doubt abot it
02:07 AM miss0r: I did, however, cut some sheet steel with it :D
02:08 AM miss0r: The next door neighboors kid(age 11) started messing with computer case modding. so he had me cut out a 'CS:GO' logo in the cabinet side. It did 'ok'
02:10 AM gloops: i think they made some upgrades for the original xcarve, apparently z was made of rubber, but it can be made into a decent machine with some bracing
02:10 AM gloops: its still machine, should be running all hours
02:12 AM miss0r: it was rubber. no doubt. I cut a (from memory) 1000x45x4mm steel sheet, and bolted it in between the x-axis rails, to stiffen them up. then I added support to the y-axis rails. I did a new z-axis carrige and installed a dewalt router instead of the electric motor with an er collect on it
02:14 AM miss0r: I've seen it before. CNC routers trying to pass a generic chinesium sheetmetal motor with small bearings off as a spindle worth a damn
02:14 AM gloops: well theyre charging $250 an hour for large format routing in the states allegedly
02:15 AM miss0r: it had absolutly no radial support. it could move up and down 2-3mm. That ofcourse is also after it was used some time by a friend of mine
02:15 AM miss0r: holy...!
02:15 AM miss0r: hmm... does 1000x1000mm count as large format?
02:16 AM gloops: no not really, and they are cutting like 600ipm, so would have to adjust pricing accordingly, watch bill griggs videos, hes on facebook - he is real lol, he does a pricing talk
02:17 AM gloops: standard size is 8x4 plus - so you can load a standard 8x4 sheet of ply or particle board or whatever
02:18 AM miss0r: hehe. If I had a router that size I would hardly have spare room to fit a drillpress in here
02:19 AM miss0r: XXCoder: Did I show you the pictures of my shop yesterday?
02:19 AM XXCoder: build a bigger shop ;)
02:19 AM XXCoder: miss0r: nah I finally had internet access yeserday
02:19 AM XXCoder: was only on for a bit
02:19 AM miss0r: If you are interrested, i'll find the picture again?
02:20 AM XXCoder: yeah
02:21 AM miss0r: http://picpaste.com/IMG_1313-eW5CgroJ.JPG http://picpaste.com/IMG_1317-rGGyVivL.JPG
02:21 AM miss0r: As you can see, I haven't got alot of room left :)
02:22 AM XXCoder: indeed
02:22 AM XXCoder: still, you can actually stand in it
02:22 AM XXCoder: our garage is total full
02:22 AM XXCoder: result of moving from bigger house to smaller.
02:23 AM miss0r: hehe i'll bet that would happen to me as well. So far we've only moved from smaller to bigger.
02:23 AM XXCoder: I'm going to throw away, give away, or donate so much stuff.
02:23 AM miss0r: But this time I think I'll stay till the coroner has to carry me out
02:24 AM XXCoder: as long as its not from under your stuff
02:24 AM miss0r: I hope not :) Everything here is bolted down, so that would take a dissaster to move it
02:24 AM XXCoder: nice
02:25 AM miss0r: I'm lucky enough to have a 250mm thick steel reinforced concrete floor - it does nicely
02:30 AM miss0r: XXCoder: You need to get that router of your back up and running. Not being able to create stuff must make you insane. It would drive me nuts, thats for sure
02:31 AM XXCoder: its havent been too productive
02:32 AM XXCoder: problems abound heh
02:33 AM miss0r: :] I keep forgetting what router you are using?
02:33 AM XXCoder: chinese 3040
02:33 AM miss0r: ahh. The generic chinesium :) the 3040 is the smallest one, right? if that is the case - thats what I started using as well
02:34 AM XXCoder: its not smallest anymore there is tinier ones now lol
02:34 AM XXCoder: $120 ones
02:34 AM miss0r: wow
02:34 AM * miss0r hits fleabay
02:35 AM miss0r: my god. Just when you thought china couldn't possibly make a worse product :o
02:35 AM XXCoder: there is turtles all way down
02:36 AM XXCoder: im sure they will find a way more
02:36 AM gloops: haha, 2 engineers talking about buying a router? you could make one to industrial standards
02:36 AM XXCoder: im not an enginner :P
02:36 AM XXCoder: im barely a machinist. certainly a cnc operator.
02:37 AM miss0r: atleast they are, for once, being reasonable about it capabilities: "It can only cut foam,paper,thin leather material."
02:38 AM miss0r: But knowing the chinese products, thats probally even exaggerated.
02:38 AM XXCoder: myfordboy upgraded one to cut alum
02:38 AM miss0r: I'm not an engineer either. I'm an electrician with an expensive hobby shop
02:38 AM XXCoder: worked fine
02:39 AM gloops: 150 is a lot for a pair of automatic scissors lol
02:39 AM miss0r: XXCoder: I think that is a matter of definition. speed+surface finish+acuracy
02:39 AM miss0r: gloops: slow automatic scissors - don't forget slow
02:39 AM XXCoder: what he did was pretty decent
02:40 AM miss0r: XXCoder: link?
02:40 AM XXCoder: way below commerical but yeah
02:40 AM XXCoder: a sexc
02:40 AM miss0r: Do any of you guys know where I can get a descent rigid tapping head for an even fore descent price?
02:40 AM XXCoder: https://www.youtube.com/watch?v=8AhJpm_llvY there is later videos
02:41 AM archivist: for rigid you dont need a head
02:42 AM archivist: you do need proper machine taps though
02:43 AM miss0r: archivist: My mill supports rigid tapping. But having a bit of springyness in the tool holder wouldn't harm I think. And I only use machine taps around here
02:43 AM miss0r: XXCoder: Okay, it does surprisingly well, I will have to admit that
02:44 AM XXCoder: yeah he later mills on metals after he upgrades machine with some cast alum metal parts
02:44 AM XXCoder: and better spindle
02:44 AM miss0r: yeah. he basically build a new router on top of the old frame :)
02:46 AM XXCoder: yeah less plastic
02:46 AM gloops: router is a cinch if you can weld and have a drill press
02:48 AM miss0r: gloops: Yeah. absolutly. but its all about the accuracy of the end product. I don't like large welded contructions for precision.
02:48 AM IchGucksLive: morning from germany ;-( The world never sleeps
02:49 AM IchGucksLive: miss0r: thats what THC is for
02:49 AM miss0r: THC?
02:49 AM IchGucksLive: i'm fine on 10mm bending
02:49 AM miss0r: so tell me. are you surviving the storm situation?
02:50 AM miss0r: I feel lucky it passed just to the north of us
02:50 AM IchGucksLive: large 3mx2m construct on 80mm sqare tube
02:50 AM miss0r: north=south
02:50 AM gloops: you basically got 4 rails to level and align, my solution is to have them bolted in slots so they can be adjusted, worked on my prototype
02:50 AM miss0r: it can be done. absolutly. its been done. If I had the space I would absolutly build one that could do complete sheets of wood
02:51 AM IchGucksLive: miss0r: Tourch hight control
02:51 AM miss0r: :]
02:51 AM IchGucksLive: for wood just mill you a ground plate flat after
02:53 AM gloops: common trend seems to be to have the long axis as the gantry, that presents major deflection issues
02:53 AM IchGucksLive: ok im off out in the fog plouing a hekta or 2 (100) to go Fahr Deuz worrier is filled up and ready to go
02:53 AM XXCoder: gloops: not as long as sideload is very low, like plastic or wood cutting
02:53 AM IchGucksLive: gloops: you can oveercom this with rack pinion
02:54 AM gloops: Ichs i mean the beam bending
02:54 AM IchGucksLive: no use of ballscrews
02:54 AM archivist: the drive does not change deflection of the gantry
02:55 AM gloops: XXCoder well you got cutting forces and the leverage of the z axis, 8-10 foot beam, needs to be strong
02:55 AM IchGucksLive: if you use AL profile 90x90
02:55 AM IchGucksLive: you are up with no bent at 3meters
02:55 AM IchGucksLive: more i go gor 90x135
02:55 AM miss0r: that sounds a bit iffy
02:55 AM XXCoder: "strong" is meaningless, better use "stiff"
02:55 AM gloops: that would twist Ichs
02:56 AM IchGucksLive: no with support at 50cm
02:56 AM gloops: 8x4 inch ally box sags under its own weight over 8ft
02:56 AM IchGucksLive: you do not need the underSpace
02:57 AM gloops: what is the advantage of a long gantry? i cant see it, if the area is 8x4 surely it makes sense to have a 4ft span
02:57 AM IchGucksLive: gloops: https://www.youtube.com/watch?v=W-24T2lqgH4
02:57 AM XXCoder: cheaper interms of rails and screw?
02:58 AM IchGucksLive: the real mashine got 2 more supports in X
02:59 AM IchGucksLive: one more between the legs
02:59 AM IchGucksLive: at 17USD per meter
02:59 AM gloops: thats with the gantry over the short span though Ichs, the big industrial machines have the gantry over the long span
03:00 AM IchGucksLive: its the long span
03:00 AM IchGucksLive: 2 motors per side driving the Gear
03:01 AM IchGucksLive: later ;-)
03:07 AM gloops: yes getting late enough to make some noise
03:09 AM XXCoder: https://www.youtube.com/watch?v=XOxM_NekH3k
03:12 AM miss0r: I don't like easel... Its what came with the x-carve as well. I ended up using a generic post processor in mastercam and feeding it to the x-carve with universal g-code sender
03:13 AM XXCoder: im unsure what to use for cam
03:13 AM gloops: not tried it, v carve or aspire
03:14 AM miss0r: I've heard good things about the free fusion software
03:14 AM miss0r: a nice price/effect ratio (with be being free'n all)
03:14 AM XXCoder: windows only
03:14 AM miss0r: I'm sure it can output g-code to feed into linux cnc
03:14 AM archivist: use insiderearofskull cam its free!
03:15 AM gloops: i havent had time to try all the open source options, Blender can draw anything and the CAM plugin looks OK, but not tested it
03:15 AM gloops: yes miss0r theyre all using fusion
03:15 AM miss0r: archivist: I'd like to see you do some 3d contouring with it :)
03:16 AM miss0r: gloops: Who are 'they' ?
03:17 AM gloops: miss0r diy machine builders - the ones who dont buy the vectric apps mainly seem to be on fusion, i only looked at it, didnt like the look of it so never went back, it is a capable app no doubt
03:18 AM miss0r: I'm running MasterCAM X5, on a license borrowed from a friend of mine :) It has the upside of free tech support a phonecall away(said friend)
03:19 AM gloops: half the battle
03:19 AM miss0r: I looked at the fusion as well. It didn't realy speak to me either. And that is annoying, as someone already wrote a post processor for my maho mill for fusion. I had to do that myself for mastercam
03:21 AM archivist: miss0r, the bevel gear generation is 3d :)
03:22 AM miss0r: archivist: That doesn't count, and you know it ;)
03:22 AM archivist: effin cam cannot do that any way
03:23 AM archivist: also my escape wheel used a slitting saw to cut the curved teeth
03:24 AM miss0r: I have to run. The technician will be here any sec. I'll write an update here after
03:25 AM archivist: if the curve can be described by maths then you can hand code it
03:25 AM gloops: hmm, i got a strange boring kind of attachment in a bucket of bits i bought last week, ill have to get a pic and post it later, someone might know what it is - useless to me
03:25 AM archivist: pic or it didnt happen :)
03:26 AM gloops: ill get one - probably an expensive item if you had to buy one, i cant see any use for it
03:27 AM gloops: got some v blocks faceplates chuck keys stuff like that, all small stuff
03:27 AM archivist: internal curves with a boring head are quite good
03:28 AM archivist: used mine to resurface one of the bearings for Leawoods engine
03:28 AM gloops: ahh curves might be for that, it has two slides on ribbed guides, thought it might involve offsettin the cutter or something
03:34 AM gloops: anyway bbl
04:23 AM XXCoder: https://www.kickstarter.com/projects/2130625347/goliath-cnc-an-autonomous-robotic-machine-tool-for lol
04:23 AM XXCoder: miss0r: ya there
04:29 AM XXCoder: https://ksr-ugc.imgix.net/assets/018/490/446/7cdb6e4c2b83339cc32b74312ad225be_original.png?w=680&fit=max&v=1506452789&auto=format&lossless=true&s=7d1e2e5f5734cab37752456796afee64
04:29 AM XXCoder: LOL
04:30 AM XXCoder: not even $5 million machine can do that
04:30 AM XXCoder: +- 0 tol my ass
04:30 AM XXCoder: "Goliath’s software communicates 100 times per second with Goliath effectively reducing the amount of latency between the machine and sensors."
04:31 AM gloops: archivist - https://postimg.org/image/15ejzddj7f/
04:33 AM archivist: gloops, a capstan tool
04:33 AM gloops: ahh right, suspected something like that
04:33 AM archivist: just about to fly, steaming at leawood today
04:34 AM gloops: have a nice day
05:45 AM DaViruz: how much glue logic is reasonable to put in hal?
05:50 AM DaViruz: that's probably not a very good question
07:16 AM slipalong: Anyone know if fusion 360 produces G code?
07:16 AM slipalong: Cant see how to do it
07:17 AM gloops: yes it does
07:17 AM gloops: but i dont use it so cant really help
07:17 AM gloops: from what i see people saying it isnt too easy to pick up either
07:25 AM slipalong: Ive used Inventor 2016 pro and thats not too bad. But was thinking of going fusion360.
07:25 AM DaPeace: slipalong: yes. it exportes gcode with varios postprocessors
07:26 AM slipalong: Do the g code generators have a facility to account for your vice / clamps
07:27 AM DaPeace: yes. you can create the stock in 3D and set it as stock and then its working around
07:28 AM slipalong: what should I do draw my vice so it knows where it is to avoid it?
07:29 AM DaPeace: yes. ive had a look right now.. you create the clamps and stuff in 3D and select it as fixtures. than its calculating the toolpath around it
07:30 AM slipalong: cool thanks. Im just getting ready to run my first job after converting and I don't want any expensive mistakes
07:31 AM DaPeace: i use it a lot without fixtures but my machine is a little simpler and the parts i process too
07:31 AM gloops: what machine is it slipalong?
07:32 AM gloops: like mill, router ?
07:36 AM slipalong: Its a AMA25LV
07:36 AM slipalong: Grizzly G0704 look alike
07:37 AM gloops: i dont know many mills - looks ok though
07:37 AM gloops: anyway off out
07:45 AM Loetmichel: hihi. wife just got a speeding ticket. 16kph to much-> 35€. Thats what happens when you badmouth your husband for having to pay 25€ for a speeding ticket ;)
08:30 AM Jymmm: Loetmichel: you both lose and insurance goes up
08:31 AM Tom_L: pron: https://www.youtube.com/watch?v=LK6a1hmlq88
08:31 AM Loetmichel: Jymmm: hu? why should it?
09:22 AM DaViruz: 35€ :O
09:22 AM DaViruz: minimumn for speeding here is like 500€
09:24 AM CaptHindsight: still lotsa suckers https://www.kickstarter.com/projects/2130625347/goliath-cnc-an-autonomous-robotic-machine-tool-for
09:24 AM CaptHindsight: traditional CNC 96" x 25" LOL
09:25 AM CaptHindsight: it's for art projects
09:26 AM CaptHindsight: maximum feedrate with no load, wtf?
09:28 AM CaptHindsight: I wonder what its terminal velocity is when dropped from an aircraft?
09:30 AM CaptHindsight: Aug 2018 delivery, that's 10 months out
09:37 AM CaptHindsight: archivist: ever seen a listing of Bridgeport head serial numbers to production dates? Not the serial numbers on the base near the Y axis crank
10:00 AM gregcnc: they're putting a lot of faith into those tires on that routerbot
10:04 AM HighInBC: gregcnc: I can't imagine that working right with just dead reckoning
10:04 AM HighInBC: unless they have some system to locate its position and orientation in real time
10:06 AM gregcnc: maybe the base is filled with depleted uranium
10:07 AM HighInBC: frickin laser beams
10:10 AM gregcnc: hah you have to scroll way to the bottom to see the two lines it uses to track position like the plotters that hang on the wall
10:43 AM CaptHindsight: CNC machine designers must be idiots, why have a rigid table and gantry if you can do it all with skate wheels and string
10:44 AM syyl: of course! because they are stuck in their narrow view of things!
10:44 AM CaptHindsight: why didn't anyone think of this before? :)
10:44 AM syyl: ask a maker to build a proper machine tool!
10:44 AM syyl: sorry. startup ;)
10:44 AM CaptHindsight: is that like a hacker? :)
10:45 AM syyl: more like a hack
10:45 AM syyl: ;)
10:46 AM syyl: maybe that could be upscaled?
10:46 AM syyl: a kuka-robotarm ontop of an old t34 tankchassis?
10:47 AM syyl: with a nice motor-spindle on the end of the arm
10:47 AM syyl: onsite machining.
10:47 AM enleth: that "traditional CNC" photo of a tiny wobbly chinese piece of crap takes the cake
10:48 AM syyl: haha
10:48 AM syyl: thats what the makercrowd thinks of cnc
10:48 AM CaptHindsight: there must be quite a surplus of old tanks strewn about
10:48 AM enleth: I'm offended by implicating hackers in this, though
10:48 AM syyl: lol ;)
10:48 AM CaptHindsight: now a mobile cnc shop thats an idea
10:49 AM CaptHindsight: like a food truck
10:49 AM syyl: but nothing new
10:49 AM enleth: CaptHindsight: funny thing is, you could do it right, it just wouldn't be cheap
10:49 AM syyl: emergency organisations have stuff like that
10:49 AM CaptHindsight: hang out at hacker events and run parts
10:49 AM syyl: the part of siemens that works on turbines onsite, for installations, has a shipping container with lathe/mill/whatnot
10:50 AM enleth: it would sure be nice to show up at CCC with an 18-wheeler that folds out the sides into a machine shop
10:50 AM gloops: well they already have those for bricklaying
10:50 AM syyl: and real onsite cnc-machining where you drop a machine in place is also common
10:50 AM syyl: in heavy industrial applications
10:50 AM syyl: just google "onsite machining"
10:50 AM syyl: boggles the mind :D
10:51 AM CaptHindsight: need a new table top? call T34 on site CNC
10:51 AM syyl: haha ;)
10:51 AM CaptHindsight: heh call , how old am I?
10:51 AM CaptHindsight: just press the app
10:51 AM syyl: app!?
10:51 AM CaptHindsight: new cabinet door, no problem
10:52 AM syyl: need to get rid of a workmate?
10:52 AM syyl: no problem
10:52 AM syyl: *mill**mill*
10:52 AM CaptHindsight: that icon thing on your phone
10:52 AM CaptHindsight: the one shaped like a tank
10:53 AM gloops: in a quarry, direct cutting statues out of rock
10:53 AM gloops: cuts out the middle men
10:53 AM CaptHindsight: cut, blast away
10:53 AM gloops: water cut
10:54 AM CaptHindsight: at T34 CNC we blast away then perfectly cut your stone to your specifications
10:54 AM gloops: water canon with .01 jet cuts through titanium
10:55 AM CaptHindsight: yeah but T34's has 4" guns, only metric
10:55 AM CaptHindsight: sorry 3"
10:58 AM gloops: t34 was a war winning design
10:59 AM CaptHindsight: https://youtu.be/GW2U0qORdLE?t=9m20s also solves parking problems
10:59 AM gloops: but was it truly russian?
10:59 AM CaptHindsight: as any Ruskie, of course :)
10:59 AM CaptHindsight: they invented everything first
11:00 AM CaptHindsight: ^^ old cold war joke for those too young
11:00 AM gloops: i think the brits helped them
11:01 AM gloops: we also foolishly gave them the plans for a functioning fast jet engine
11:05 AM enleth: they'd just take a slow one and threaten it with a gulag if it doesn't run faster
11:43 AM gloops: Daily Mirror‏Verified account @DailyMirror 42m42 minutes ago
11:43 AM gloops: Japanese woman 'dies from working 159 hours overtime' with only two days off in one month
11:43 AM gloops: man, the japanese are going soft these days
12:08 PM IchGucksLive: hi all from a cold rainy germany
12:09 PM HighInBC: greetings from cold rainy canada
12:09 PM IchGucksLive: gloops: how has been the mounting day ;-)
12:10 PM IchGucksLive: gloops: why do british citicens like to drive on sideway
12:15 PM gloops: Ichs this is another vile terror act - need to start shipping some people out of here
12:16 PM IchGucksLive: agree some dont need to be here
12:16 PM IchGucksLive: others are very welcome
12:16 PM gloops: well, UK is generally anti immigration
12:17 PM HighInBC: funny considering how much they liked spending time in other peoples countries
12:17 PM gloops: this economic model is useless
12:17 PM gloops: High visiting is different to migrating
12:19 PM IchGucksLive: it will change on Ecars
12:19 PM IchGucksLive: as about 600000 people will be off the fuel car production
12:23 PM gloops: cant see the EU lasting long anyway
12:34 PM IchGucksLive: hi BeachBumPete 2 more big storms in the region
12:48 PM BeachBumPete: hey Ich
12:48 PM BeachBumPete: yeah apparently
12:48 PM BeachBumPete: beautiful day here ;)
12:51 PM IchGucksLive: as always bevor and after a storm
12:52 PM BeachBumPete: whats your point?
01:07 PM Tom_L: nice day here too
01:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/mushroom.jpg
01:08 PM Tom_L: looks not edible to me
01:10 PM BeachBumPete: WTF is that?
01:10 PM Tom_L: pulled it out of the yard

01:11 PM Tom_L: i pull them out too
01:16 PM hazzy: We usually have a bunch of mushrooms in our yard, but hardly any this year
01:16 PM hazzy: been too dry I guess

01:19 PM IchGucksLive: hi chupacabra
01:20 PM IchGucksLive: chupacabra: just ask if you need help
01:41 PM IchGucksLive: im off Gn8 from germany
02:05 PM HighInBC: if I get the wiring mapped right, can I just wire an arduino nano with GRBL to a parallel port and use it on a stock parallel port based CNC?
02:20 PM skunkworks: yes
02:21 PM skunkworks: with all the grbl limitations
02:29 PM HighInBC: Nice to be able to try it out without modding my existing system
02:29 PM HighInBC: thanks
02:29 PM HighInBC: easy to switch
02:44 PM gloops: well the chinese devils have struck again, my gear aint coming
02:54 PM HighInBC: hmm I am guessing I need to hook pins 18-25 on the db25 to the nano's ground so there is a return path for the optoisolators
05:01 PM HighInBC: Lets see if my first attempt works: https://oshpark.com/shared_projects/1K4tRAGy
05:07 PM HighInBC: based on this http://images.highinbc.com/GRBL_DB25_adapter.pdf
05:10 PM HighInBC: gloops: I feel your pain
05:10 PM HighInBC: I have a brew system partially complete due to me planning on an obscure part that is never going to come
05:20 PM HighInBC: my new linuxcnc computer is named: highincnc
05:55 PM Daniel-2818: Hey guys, do you use a direct coupling between the stepper motor and the ballscrew or a toothed belt?
05:55 PM Daniel-2818: And what would you recommend for what reason?
06:05 PM gloops: you want stops on if youre using those flexi shaft connectors they snap like cotton
06:18 PM gloops: unless you want to change the gearing though, adding belts pulleys chains and so on increases chances of backlash - and more moving parts more breakdown potential
