[02:25:45] <Deejay> moin
[02:33:35] <yasnak> morning
[02:38:52] <witnit> mojn!
[02:42:16] <Deejay> :)
[03:02:19] <witnit> zeeshan: were you the one redoing the yasnac controls?
[03:29:25] <Swapper> pcw_home: Hi, quick question, do you know if there are any readymade bitfiles for the 7i80 that can run a 7i77 on one port and a "bob" with stepgens on the next port?
[04:32:13] <minibnz> how is everyone.. im stuck with a descision to make.. two job offers one pays half as much as the other but they have mills and lathes i get to use and is with a mates company.. the other is more on the electronic side of things that will pay more so i can buy more machines of my own..
[04:32:45] <minibnz> if i take the higher paying job i have to work out how to tell my mate you cant afford me..
[04:36:20] <DaViruz> part time on each
[04:36:23] <DaViruz> win win!
[04:38:01] <minibnz> well the higher paying job started to look like they wanted part time and i was thinking along those lines..
[04:38:57] <minibnz> but the fulll time offer is in the city where my mates offer is out west. takes ages to cummute that. so it only leaves the weekend.. i will never get anything done :)
[04:39:07] <DaViruz> besides, your mate should understand you cant say no to twice the pay
[04:39:33] <DaViruz> and working for friends can get complicated
[04:40:13] <minibnz> he is cool but his mum runs the company (for now) so i will sorta stretch the friendship as he pushed so hard to get me a offer..
[04:40:41] <minibnz> i think i will go and decline in person.. and try not to waste any ones time..
[04:41:16] <minibnz> the other offer came out of the blue was really unexpected and looks like it will be great fun.
[04:42:29] <minibnz> working with a company that makes maps from low level arial photography. first task will be to reverse enginer a lens control protocol and make a controller to integrate with their protocol.
[04:42:33] <DaViruz> i was faced with a very simulat situation a few years back
[04:42:45] <minibnz> just hope i get to choose the MCU :)
[04:43:14] <DaViruz> still not sure i made the right choice
[04:43:35] <minibnz> as its planes i am wondering exaclty what standards i have to adhear to..
[04:43:52] <DaViruz> hate this job, but i wiuld probably have simular feelings about the other one by now :P
[04:44:15] <minibnz> its not a critical system but integrates with the planes power system so there will be something to follow.. :)
[04:44:16] <DaViruz> that sounds pretty interesting
[04:45:20] <DaViruz> i try to follow a "not working with hobby stuff" policy, but i'm not sure how wise that is
[04:45:22] <minibnz> yeah i hate these sorta choices.. but it does sound like fun at the mapping job. dont mind flying in planes
[04:46:16] <minibnz> sometimes hobby grade is great to prove a point.. if you can do it with hobby hardware just imagine what real stuff could do? :p
[04:46:31] <DaViruz> for some reason getting paid takes the fun out of things
[04:46:45] <DaViruz> for me at least
[04:47:09] <minibnz> yeah i am most farmilar with PIC MCU's and will be able to smash out a interface board in about a month depending on how complex the protocol is.
[04:48:42] <minibnz> oh so far i have not had that problem.. my old job was build boards and design solutions to problems with a linux OCR system.. basically the same sort of thing i play with at home just a little different. so it was different enough so what i was doing at home felt like fun still.
[04:48:58] <DaViruz> getting familiar with a new mcu is usually pretty easy as long as you dont intend to program it in assemblu o find
[04:49:01] <DaViruz> i find
[04:50:37] <minibnz> my last job was such a cruise any reall job is probably going to be good for me.. last 4 years (since the founder died) hardware development had dropped to the point where i was going to be made redundant but then they shuttered the whole company.. but those 4 years was spent doing foriegn orders and watching youtube while waiting for something to break around the office..
[04:51:54] <minibnz> yeah its the different conventions in the datasheets i have the hardest time with... its taken me a while but i have my head around PIC datasheets and all the cross interactions.. when i read a different MCU datasheet it almost seems like a different language
[04:53:19] <minibnz> yeah i prefer to do all my PIC code in C and a little C+ makes life nice an simple with easy to read code no reading three or for lines just to see they are loading a reg.. :) C is one line for most things :)
[04:54:52] <minibnz> the compilers do a good job. their free versions do some nasty's to make the code bigger but the chips are so cheap its ok for one off's and for production you use the full version.
[04:55:16] <DaViruz> the only time i touch asm these days it's disassembled cowhich is way more painful then writing it in the first place :(
[04:55:32] <DaViruz> code, *
[04:55:43] <minibnz> oh yeah machine gen assembly is nasty nasty stuff..
[04:56:10] <minibnz> i use it only when i really MUST know how long something takes to execute. but thats the only time
[04:57:04] <DaViruz> :better orf doing time critical stuff with timers whenever possible
[04:57:35] <DaViruz> oh well, i guess i should get back to working
[04:58:01] <minibnz> oh no.. not that sort of thing.. much faster things.. like reading and writing to the EEPROM in a PIC its time contrained to stop you accidentially writing to it..
[04:58:17] <minibnz> in general i use interrupts where ever i can..
[04:58:31] <DaViruz> ah
[04:58:36] <minibnz> PIC's have more than enough :) like most MCU;s these days.
[04:58:51] <minibnz> i will let you go earn :)
[04:58:56] <minibnz> talk later.
[04:59:24] <DaViruz> the last time i programmed for pic was 16c84
[05:00:00] <minibnz> oh they was nasty too.. they are much more C orintated now.. no more bank selecting BS...
[05:00:08] <DaViruz> oh yeah. work :P
[05:00:35] <minibnz> the compiler might be taking care of that these days.
[05:00:50] <minibnz> i havent had to touch a bank in years.
[05:19:57] <DaViruz> yeah there wasnt really any c compilers for pic back then, i knew of one which sas way too expensive for hobby use
[05:22:00] <DaViruz> re time constrictions for eeprom srites, avr works like that too, but i just do it in c. first time i tried it i douvle checked the assembly though to make sure it didnt do something stupid
[05:30:34] <DaViruz> maybe it'll bite me in the ass some day :)
[05:51:30] <archivist> I used 16F627 or 628
[06:07:27] <DRGray> Hey, I thought I had got all going ok, by on my axis test if i keep holding down in one direct about every 3 or 4 times, it switches direction, any body heard of this issue before? I’ve tried two type of drivers and I get the same issue. I’m guessing possibly some sort of timing issue?
[06:08:26] <_methods> servos, steppers?
[06:08:37] <DRGray> steppers
[06:09:36] <Jymmm> check cabling
[06:09:55] <Jymmm> what driver?
[06:10:16] <DRGray> leadshine dm422
[06:10:24] <Jymmm> link?
[06:10:35] <DRGray> http://www.leadshine.com/UploadFile/Down/DM442m.pdf
[06:10:49] <Jymmm> product link, not manual (sorry)
[06:10:57] <DRGray> i also have some cheap chinese ones i get the same issue
[06:11:08] <Jymmm> check cabling
[06:12:03] <Jymmm> shielded cable?
[06:12:04] <DRGray> ok ill double check it and see whats going on,
[06:13:38] <Jymmm> if it's changing direction randomly, and also on two different drivers, it sounds like the issue is between the computer and driver. (the DIRECTION line ;)
[06:14:27] <Jymmm> unshielded cabling, another strong signal/cable near it, could also cause issues
[06:14:27] <DRGray> i’ve tried a multimeter on the direction and it seems to be correct
[06:14:40] <DRGray> that could be it
[06:14:40] <archivist> DRGray, some break out boards do not drive the optos in the drivers properly
[06:15:12] <Jymmm> DRGray: Are you using shielded cable(s)?
[06:15:22] <DRGray> as in not producing a high enoguh signal voltage
[06:15:30] <archivist> current
[06:16:03] <DRGray> no im only connecting one motor up at the moment. i didnt think it would be to big an issue
[06:16:08] <archivist> I had to open up a driver to diagnose the design error :)
[06:16:21] <DRGray> like i said the multimeter seems to produce a constant voltage to the direction pin
[06:16:31] <archivist> which bob have you used
[06:16:39] <DRGray> following the test sequence of the axis control
[06:16:43] <Jymmm> DRGray: shack the hell out of the cabling along it's entire length =)
[06:16:51] <DRGray> ive tried it with a scope as well it seems to get to the driver fine
[06:16:52] <Jymmm> shake*
[06:17:23] <archivist> its not voltage its current to the driver opto to internally there is another resistor
[06:17:37] <DRGray> HY-JK02-m
[06:17:52] <archivist> does your bob have a series resistor
[06:17:59] <DRGray> im not sure
[06:18:25] <DRGray> let me double check the wiring
[06:18:40] <DRGray> its probably something daft
[06:18:40] <archivist> yes it does, that is the crappy one I first used
[06:19:01] <DRGray> what is the best bob at a reasonble cost?
[06:19:17] <DRGray> archivist: did you have a problem like that?
[06:19:29] <archivist> http://www.ebay.co.uk/itm/321905519866
[06:19:57] <archivist> DRGray, yes I did have a problem with lines not being driven
[06:20:24] <archivist> that one I pointed at can be had for half that price
[06:20:39] <DRGray> http://www.ebay.co.uk/itm/141684440668
[06:20:59] <DRGray> it drives fine, but then all of a sudden it changes direction
[06:21:24] <DRGray> so on the initial setup if you keep pressing and realeasing say the right arrow every 4 click it will change direction
[06:21:43] <Jymmm> check for poor solder joint/connection on BOB
[06:21:48] <DRGray> i’ve tested the output voltage though and it seems to fine
[06:22:05] <DRGray> ill solder the wires direct on
[06:22:10] <archivist> define fine :)
[06:22:39] <DRGray> no choppy ness seems to drive the stepper nicley
[06:23:11] <DRGray> ill go and tidy the wiring up and re-test and let you know what happens
[06:23:13] <archivist> there is a series resistor of about 270 ohms inside the driver AND one on the bob, then you get half current to the opto led in the driver
[06:23:24] <Jymmm> arekm: define - de = fine ;)
[06:23:31] <Jymmm> bah, archivist
[06:24:25] <archivist> your bob has two optos in series, not entirely sensible
[06:24:54] <DRGray> im guessing if i dont have shielded cable a ribbon is better? stop any twisting
[06:25:45] <DRGray> archivist: did you find a way round it or just get a differnt bob?
[06:26:18] <archivist> DRGray, I stopped using that bob
[06:26:48] <DRGray> archivist: what do you use now?
[06:27:14] <archivist> the type I pointed at on ebay, I have 3
[06:27:31] <DRGray> the 13 quid one?
[06:27:32] <DRGray> hah
[06:27:32] <DRGray> it works well?
[06:27:54] <archivist> http://www.collection.archivist.info/archive/DJCPD/PD/2015/2015_10_14_cnc_bob/IMG_2013.JPG
[06:28:39] <archivist> another top left http://www.collection.archivist.info/archive/DJCPD/PD/2015/2015_12_30_wormtest/img_2020.jpg
[06:29:23] <archivist> they are less good at encoder input, but usable with an interface see vero
[06:29:37] <DRGray> sheiled cable?
[06:29:54] <archivist> none on that setup
[06:30:34] <DRGray> just ordered that 13 quid bob just in case
[06:31:12] <archivist> I fitted a 4th to someone's machine and we needed to shield some cables because we got some noise into the encoder signal
[06:31:19] <DRGray> the driver sort of look similar to mine there all packed like that im guessing
[06:32:20] <archivist> the main difference is the 74 series chip drives the driver opto directly
[06:32:23] <DRGray> just firing up the solder iron
[06:33:05] <archivist> the inputs while less good for encoders are perfect for limit switches
[06:35:24] <DRGray> i have had issues with noise in the past, but ive found earthing the body of the device has normal removed it
[06:35:38] <DRGray> that might be a bit of a nieve way of dealing with it
[06:42:13] <minibnz> its a good start.. grounding everything together gets you a solid starting point... then start sheilding things if it still persists. i have a ribbon cable that i think i s picking up noise on the step lines for my A axis. looking at the pins they are not near as many gnd lines as the other pins so that might be why i have only noticed that now.
[06:43:18] <minibnz> still chasing a solution to the cable. i have a ribbon cable that is nice and long (40cm) that allows me to work on the box. i am going to make another ribbon cable that is shorter and see if that solves it.. '
[06:43:58] <minibnz> i dont have space for a normal sheilded cable the box that has my stepper board and PC is rather tight for space...
[06:45:38] <DRGray> shielding seems like some sort of magic
[06:45:39] <minibnz> with that i am torn as to where and how to implement my tool changer.. do i do it via a usb interface or try and squeeze it out of the par port pins i have spare on the daul card i have..
[06:46:10] <minibnz> well back in the day it was a dark art.. now its well understood..
[06:47:50] <minibnz> basically when a wire carries a high current pulse like the stepper wires, it generates a magnetic feild that is then picked up by the ribbon cable and converted into a voltage that might just be interpretated as a high or a low or both.. then things seem to happen randomly..
[06:49:08] <minibnz> when you shield the cable bunch with wire or sheet metal the magnetic pulse is captured by the sheild and gets shunted to ground. for good sheilding only one end should be sheilded. if current flows thru the sheild it is less effective
[06:49:34] <DRGray> one end? what of the cable?
[06:50:02] <minibnz> of the shield in the cable. usually the driving end (the end with the power supply)
[06:51:22] <minibnz> so for a simple test i would take some tin foil and neatly wrap my ribbon cable all the way up. then the end that connects to the parallel port would be connected to a ground.. the end of the shield at the BOB is left unconnected.
[06:53:07] <minibnz> for much higher frequencies you need to add passives to improve things but for our needs one end to ground is fine. you may find that comercial cables have a sheild that is connected to both ends, its still ok you will probably find that a good BOB will have the outside of the socket floating or high resistance to ground.
[06:53:45] <minibnz> even if your bob is not floating dont stress it will still help..
[06:54:37] <DRGray> ok ill try and digest this information at some point
[06:55:09] <DRGray> ive just redone the wries from the bob to the driver im just doing the ones from the driver to the stepper
[06:55:50] <DRGray> the power cables are very close to the stepper cables on teh driver is that ever a problem?
[06:56:24] <minibnz> sweet. try and get as much physical distance between the wires that drive the controller and tht output that goes to the steppers. this will also help a lot. atm my ribbon touches the steppers bundles as its too long for my box.
[06:58:21] <minibnz> not generally as they are considered high power signals. DC voltage is still a signal. its when the higher power signals are near the lower power/voltage signals like the 5v from the par port. my steppers run at 24v @ 3amps thats more than enough to try and flip a bit on the stpper inputs if the wires are bunched up too close.
[06:59:23] <minibnz> i have been poking around in my box a fair bit adding bits and peices and need to get some distance between them by cable tie'ing em up nice and neat..
[07:00:10] <DRGray> my motors are rated at 3.5v 1.8 amps. i have a 20 volt power supply is that ok?
[07:00:11] <minibnz> you can also shield from the other side as well.. if you shield the noisy cable that will help prevent it reaching the 5v signals with full strength.
[07:00:31] <DRGray> im guessing 20/3.5 = result * 1.8 = amps
[07:01:06] <minibnz> that could be ok but it might not be.. do you have a datasheet handy for the steppers?
[07:01:39] <minibnz> im not 100% certain on this but.. i have heard that that voltage doesnt really matter all that much on the larger steppers.
[07:01:52] <archivist> larger voltage is better
[07:01:54] <DRGray> current 1.8amp/phase, resistance 1.75ohm bi polar two colis
[07:02:02] <archivist> driver limits the current
[07:02:12] <DRGray> thats about all there is on the data sheet :)
[07:02:24] <archivist> you can step a lot faster with a higher voltage
[07:02:55] <minibnz> archivist is correct but at some point there has to be a limit of what you should use.. if he has a tiny little dvd stepper that would probably let the magic smoke out
[07:03:29] <archivist> 1.8 amp is not tiny dvd stepper
[07:03:36] <minibnz> ok so you know its the current that you need to keep under control.
[07:03:52] <DRGray> ok
[07:05:07] <minibnz> i know that archivist, was just making a point. to be careful.
[07:05:25] <DRGray> i appreciate points :)
[07:05:50] <minibnz> the more voltage you use the more heat that is generated too..
[07:05:57] <DRGray> i have a proxxon miller thats what im tryig to automate at the moment im trying no to melt it
[07:06:49] <minibnz> oh those green sub micro mills.. looked at one of those when i started looking... then settled on a seig X2
[07:07:14] <minibnz> still should be good to light work. all depends on your needs.
[07:07:18] <DRGray> it seems pretty well put togehter
[07:07:34] <DRGray> well i like the 3 axis, i might use it for some other jobs as its quite easy to take the miller off
[07:07:42] <DRGray> just seems like a nice solid construction
[07:08:10] <minibnz> i purchased a proxon diving head chuck and powered that. they do make some nice bits.
[07:08:43] <minibnz> the motor was too small for me and my big ideas :)
[07:09:13] <archivist> the technical reason for more volts is the inductance of the motor coils, higher voltage is faster rise time
[07:09:56] <DRGray> as in rise from 0 - xvolts?
[07:10:05] <archivist> yup
[07:10:35] <DRGray> i must of learnt something at college
[07:10:39] <archivist> well current rises slowly in an inductor
[07:10:47] <minibnz> i just havent looked into why they always say the coils are always rated at low voltages.
[07:11:04] <archivist> the low rating is pure dc
[07:11:09] <DRGray> from what i understand its at x volts it will be using y amps
[07:11:14] <DRGray> double the voltage double the amps
[07:11:32] <archivist> the resistance sets that value
[07:12:06] <archivist> use a current limiting driver and the voltage limit almost disappears
[07:12:40] <DRGray> ok
[07:12:47] <DRGray> ready to test :-S
[07:12:53] <minibnz> upto the point where the insulation gets soft :)
[07:13:14] <DRGray> ok fixed it :D
[07:13:27] <DRGray> really dum mistake but bizare out come
[07:13:53] <DRGray> the proxon comes with 9 pin connectors. so i bought a break out bored connector to wire it in
[07:13:58] <minibnz> not obvious until you have seen/suffered it once or twice..
[07:14:17] <DRGray> i i wired in coila 1 to the wrong pin
[07:14:20] <DRGray> so there was nothing going to it
[07:14:29] <DRGray> it must of been strangly running off one phse
[07:14:37] <minibnz> ahhh that will do it.
[07:14:50] <minibnz> do you have micostepping on the driver?
[07:14:54] <DRGray> man that was really doing my head in i thought i had checked everything over with teh multi meter
[07:14:56] <DRGray> yes
[07:15:06] <DRGray> im not micro stepping at the moment just whole steps
[07:15:16] <DRGray> im going to wire up the other two mother now
[07:15:19] <DRGray> after a coffee
[07:15:30] <minibnz> sweet
[07:15:54] <DRGray> im not sure about all the other settings so be prepared for a few more questions later?
[07:15:56] <DRGray> :-)
[07:16:09] <DRGray> thanks for all your help thiough it really helped me just follow the process though
[07:16:23] <DRGray> sometimes its a bit hard when your bashing your head against the same problems
[07:16:23] <minibnz> no problems.
[07:16:35] <minibnz> been there.. done that..
[07:51:47] <witnit> Most of the time when I was first getting started I would have a problem like that and just be so totally lost, im very glad I have the experience now to realize im usually missing something simple. I can't count the times I have misswired or misunderstood code and been stumped for a couple days solid.
[07:52:24] <witnit> Proofreading your own work can be troublesome
[08:08:30] <MrSunshine> gaaah im going nuts on my X axis .. something isnt right and i dont know what .. :/
[08:10:25] <gregcnc> what kind of problems are you having?
[08:10:55] <MrSunshine> the ballscrew works fine the first 2/3 of the way but at the end it starts to bind up for some reason ...
[08:11:03] <MrSunshine> and noise from it
[08:11:17] <MrSunshine> like resonanse noise at some parts but not others
[08:12:12] <MrSunshine> when pulling it by hand it works very smooth the first 2/3 but then gets shoppy at the end
[08:12:17] <MrSunshine> choppy
[08:12:40] <gregcnc> with no stepper?
[08:13:04] <MrSunshine> yeah, disconnected the stepper so i could feel the screw
[08:13:32] <gregcnc> and this wasn't a problem before you installed it?
[08:13:54] <MrSunshine> ive changed the screw on the machine to a higher pitch one
[08:14:05] <MrSunshine> and before that no .. not a problem with the old screw
[08:14:30] <MrSunshine> the machine can handle it .. but i do not like the sound =)
[08:14:46] <MrSunshine> so it doesnt stall or anything but i want stuff to work smoothly =)
[08:14:57] <gregcnc> so the nut runs as it should on the screw?
[08:15:13] <MrSunshine> without the axis attached yes
[08:15:34] <MrSunshine> so something is pulling it in some way ... i guess im gonna have to get more indicators out and check the rail straightness or something
[08:15:48] <MrSunshine> problem is that everything is painted =)
[08:15:52] <gregcnc> that's the next step
[08:16:37] <MrSunshine> getting kinda daunted with the machine :/ feels like i never get it running as it should .. been down for a almost two months due to screw change and depression :P
[08:17:37] <gregcnc> just keep working at it.
[08:17:52] <MrSunshine> i guess i can check it on the paint as if its a huge error it should atleast indicate me to that there is a huge error =)
[08:19:22] <gregcnc> did you have the bend screw problem or someone else?
[08:22:10] <MrSunshine> they are a tad bit bent
[08:28:41] <witnit> maybe if you put your indicator on the side of the screw and drive the nut down until it started to get hard to turn. if you watch which way the indicator moves you can see which direction the shaft being pulled toward in an alignment issue. If the indicator goes up then back down then you may suspect a bent shaft
[08:28:46] <witnit> MrSunshine: ^
[08:29:04] <gregcnc> I can't remember if a tad is .010" or .1" TIR.
[08:29:51] <gregcnc> what happens if you loosen the bearing mount supporting the far end of the screw?
[08:29:53] <archivist> gnats cock^3
[08:34:44] <MrSunshine> gregcnc: smoother so it feels like the nut is twisting on the mounting plate
[08:35:07] <MrSunshine> gonna do more measurements on everything ...
[08:35:19] <MrSunshine> better do it right now than half ass it then have to do it over again later :P
[09:15:32] <Simonious> I know T1 is tool 1, what is H1?
[09:15:41] <_methods> height offset 1
[09:15:52] <_methods> tool length offset
[09:16:06] <_methods> however you prefer to call it
[09:16:14] <Simonious> so.. when using tool 1, one should also use H1.., right?
[09:16:24] <_methods> sure if you want to
[09:16:31] <_methods> that is typically how you would do it
[09:16:52] <_methods> unless you need to use another length offset for that tool to provide a finer tolerance for something
[09:17:25] <Simonious> thanks
[09:20:29] <_methods> np
[09:21:52] <gregcnc> Simonious are you using G43?
[09:22:38] <Simonious> uhm..
[09:22:43] <Simonious> looking
[09:22:50] <gregcnc> H1 does nothing without G43
[09:23:04] <Simonious> yes, it's using g43
[09:24:10] <gregcnc> quick change tooling or tool Z probe?
[09:33:03] <anomynous> first part with self "made" fixed position vise work offset :D So nice not needing a probe. Count parallers + part thickness from vise way upwards for z-zero :D And x and y in stationary jaw
[10:05:04] <DrNoboto> hey guys, i'm wondering what the easiest way to change the max speed on an axis is
[10:05:17] <DrNoboto> in other words, i want to copy my existing configuration, but allow higher speeds on one axis
[10:05:38] <DrNoboto> i tried modifying a config using pncconf but for some reason the other 2, non-modified, axes die when i do that
[10:05:43] <DrNoboto> no idea what's going on there
[10:06:09] <DrNoboto> might work better if i just change something in the config manually
[10:09:33] <archivist> DrNoboto, edit in an editor, not pncconf
[10:09:44] <DrNoboto> that's what i was suggesting
[10:09:48] <DrNoboto> but i don't know what to change
[10:09:49] <DrNoboto> ...
[10:11:11] <DrNoboto> i see values for maxaccel and maxvel several times in several of the different config files
[10:11:51] <archivist> edit a maxvelocity of the axis you want and try it
[10:13:02] <DrNoboto> in .hal, .ini, or both?
[10:13:41] <DrNoboto> i guess i need to raise the values in [TRAJ] as well...?
[10:19:08] <DRGray> hey all im back and much progress
[10:19:26] <DRGray> i dont trust my dip switches on my drivers
[10:19:47] <DRGray> while its holding a motor should i just be able to read a voltage / amperage across a phase?
[10:22:03] <archivist> DRGray, it is a switching waveform so you only get an average
[10:22:37] <DRGray> ah so even when holdig its rapidly switching between two?
[10:22:39] <archivist> not something you usually bother to measure
[10:22:57] <DRGray> well i just want to know if when i change the dip switches for my current its delivering what it says on the box
[10:23:08] <DRGray> ive seen a few web posts saying the dip switch settings are inacurate
[10:23:12] <archivist> just measure power supply if anywhere
[10:23:35] <DRGray> sharing a power supply between 3 motors so just divide the amperage by 3 im guessing
[10:32:23] <MrSunshine> sigh, looks like the distance to the rails to the beam they are attached to is off ...
[10:37:06] <DRGray> well it seems to be running smoothly even at 10 volts off the power supply i was using 20 but ive cut it down as the motors were getting warm
[10:42:12] <MrSunshine> is there any way to stiffen a rectangular profile without adding to much weight to it? =)
[10:42:23] <MrSunshine> so it wont sag so much when hanging free
[10:43:04] <archivist> see bridge and roof trusses for inspiration
[10:43:20] <MrSunshine> yeah was thinking some kind of /\ inside the beam
[10:44:03] <archivist> below/above
[10:44:48] <MrSunshine> but shouldnt it work if inside it also ? =)
[10:51:45] <gregcnc> can you add another leg in the middle, makes level tougher, but not impossible. or an under deck stay cable like some bridges? how big is this router?
[10:53:08] <MrSunshine> its a gantry router and its the X axis =)
[10:53:18] <MrSunshine> 1.5 meters wide
[10:56:20] <pink_vampire> hi

[11:39:37] <MrSunshine> hmmm, i realy should make a sled that goes on the rails somehow to check the straightness but i dont know how i should make it :P
[11:42:56] <archivist> either use a level, or a laser pointer and a mirror
[11:43:25] <MrSunshine> archivist: yeah .. but the straightness to the side of the beams i mean now =)
[11:43:53] <MrSunshine> not length wise or so .. just that the rails are just right to the side where the screws are mounted
[11:44:11] <archivist> mirror and laser works in any plane
[11:45:11] <MrSunshine> archivist: any info on how you mean? =)

[11:51:13] <archivist> if you have a level with a laser out the end on the frame pointing at a mirror on your moving item, adjust until it reflects back, move frame see if reflection moves, posh method is with an autocollimator
[11:52:10] <pink_vampire> how the turret get lock do precise?

[12:19:51] <SpeedEvil> woof
[12:21:49] <maxcnc> hi all from a winter wite Germany
[12:55:40] <DRGray> is there anyway of controlling linuxcnc remotly?
[12:55:48] <DRGray> as in sending commands to it over the network?
[13:00:59] <DRGray> are there logs for this chanel?
[13:01:26] <cradek> zlog:
[13:02:48] <DRGray> thanks :D
[13:05:39] <maxcnc> DRGray: you can make your nice pendant like xhc-hb04 to get things done
[13:05:56] <maxcnc> DRGray: also work with user Mcodes to set things you want
[13:07:09] <DRGray> erm i kind of want to be able to send signals from another computer say transmit mcode across the network so i can control it like a robot
[13:07:53] <cradek> a user-defined M code (M100, M101, ...) can be set up to run any shell script or program on the system
[13:09:51] <DRGray> yes but i want to send mcodes to a running version of linux cnc
[13:10:23] <DRGray> codes. not mcodes specificially
[13:10:49] <DRGray> i suppose i want to do the equivelant of attach to the console remotly
[13:11:19] <Jymmm> DRGray: what are you REALLY trying to accomplish?
[13:11:40] <DRGray> i want to use the linuxcnc as a black box for being able to control the cnc.
[13:11:52] <DRGray> then from a remote program being able to send it commands to control the cnc
[13:12:43] <Jymmm> Why dont you just use an arduino for that?
[13:13:47] <DRGray> i’ve written a basic controller before on the arduino, but linux cnc is easy to configure.
[13:14:04] <DRGray> there is a lot to take in to control a 3 axis nicely
[13:14:54] <DRGray> i dont really want to re-invent the wheel
[13:21:47] <DRGray> linuxcncrsh - a telnet based user interface which allows commands to be sent to LinuxCNC from remote computers.
[13:21:53] <DRGray> that will probably do it
[13:32:46] <Jymmm> There's keystick, but it's a bit dated. http://linuxcnc.org/docs/2.4/html/gui_keystick.htm
[13:34:04] <DRGray> 404 dated :-)
[13:34:31] <DRGray> i think i can probably get something workign with linuxcncrsh
[13:34:37] <Jymmm> http://linuxcnc.org/docs/html/gui/keystick.html
[13:34:56] <Jymmm> There is an NON-GUI version as well
[13:35:08] <DRGray> yeah i need to send the command from a remote machine.
[13:35:17] <DRGray> im planning on using linuxcnc as a controller
[13:35:21] <Jymmm> Yes, it'll do that
[13:35:25] <DRGray> which is then run from software on another machine
[13:35:39] <DRGray> ill have a look at it
[13:35:51] <DRGray> im just going through the manual from top to bottom at the moment
[13:36:03] <DRGray> just to get the full picture
[13:36:12] <Jymmm> it may not be in the manual. But I think you are reinventing the wheel *eh*
[13:36:25] <DRGray> he he he
[13:36:50] <Jymmm> Circa 2008 https://www.mail-archive.com/emc-users@lists.sourceforge.net/msg10192.html
[13:36:57] <DRGray> in one of the first page of the manual it mention remote controling cnc
[13:37:18] <Jymmm> Remote console(s) I suspect
[13:37:46] <Jymmm> which it does have, but it sound like you are trying to bypass the use of gcode in some fashion
[13:37:47] <DRGray> anything that i can send data to and recieve a response is fine
[13:37:56] <DRGray> no i want to use gcode
[13:38:11] <Jymmm> but LIVE?
[13:38:24] <DRGray> yes the software will generate it
[13:38:38] <Jymmm> then just upload it as a gcode file
[13:38:45] <DRGray> if it wants the machine to move an axis to a specific point it will send that gcode to the box
[13:38:48] <DRGray> yeah
[13:38:49] <Jymmm> queue it up so to speak
[13:39:21] <DRGray> i already control other device either over tcp/serial
[13:39:36] <Jymmm> you are not saying what you REALLY want todo here
[13:39:43] <DRGray> you just write to a stream and get a response i want to get the same sort of scenario with linux cnc so i use it as a device
[13:40:20] <DRGray> i want to use linux cnc to control my hardware so my software doesnt have to worry about doing anything more then generating gcode commands
[13:40:28] <Jymmm> Well, good luck
[13:41:27] <DRGray> hopefully good understanding
[13:41:49] <DRGray> linuxcnc is a little beast im sure it can do it
[13:42:02] <DRGray> plus its on linux so i can probalby find someway of connecting to it
[13:43:52] <maxcnc> Gn8
[14:01:57] <MrSunshine> soo ... aligned the rails ... they were quite off .. but when measuring on the ballscrew i get a 0.2mm deflection on the screw on the middle, and i dont know if its twisted beams, bent beams or whatever :P
[14:02:33] <MrSunshine> oh well, more measurments tomorrow i guess =)
[14:09:05] <pink_vampire> there is a way to make a hing without any run-out or play?
[14:10:04] <archivist> a number of special hinges exist
[14:10:56] <archivist> a v groove, ground shaft and springs is one
[14:11:45] <archivist> for tiny amounts of bending, some mechanisms have sheet metal spring hinges
[14:12:49] <archivist> ground bar and groove is seen on a clockmakers depthing tool
[14:12:51] <CaptHindsight> interference fit brass bushing and steel pins
[14:13:37] <archivist> the sheet springs are in some of my measuring gear, they work to microns
[14:14:45] <CaptHindsight> what size hinge? how much movement? what loads? etc etc
[14:15:31] <archivist> http://www.collection.archivist.info/searchv13.php?searchstr=lvdt+probe has parallelograms using sheet spring
[14:16:07] <archivist> CaptHindsight, do you know who made that probe?
[14:16:46] <archivist> spent ages googling found nothing
[14:17:55] <pink_vampire> there is a name for it, or therm that I can google?
[14:17:57] <CaptHindsight> nope, put it up on the mail list, you never know who's seen it before
[14:19:06] <pink_vampire> the spring sheet is nice, but I want to get more than just few deg..
[14:19:55] <pink_vampire> archivist: ^
[14:20:51] <pink_vampire> how can I cut a groove with a milling machine?
[14:20:51] <archivist> kinematic hinge
[14:21:25] <archivist> https://www.precisionballs.com/KINEMATIC_ENCYCLOPEDIA.php
[14:26:10] <CaptHindsight> you finally got some snow
[14:26:59] <CaptHindsight> archivist: or was that only in France/Germany?
[14:29:08] <archivist> no snow at the moment
[14:30:17] <pink_vampire> here there is aloooot of snow
[14:31:18] <PetefromTn_> Keep it up there we don't want it here ;)
[14:31:36] <pink_vampire> archivist: other then precisionballs.com I can't find any info about that.
[14:33:55] <pink_vampire> I don't think that kinematic hinge is the correct therm for that.
[14:34:22] <joem_> they have arrived
[14:34:26] <joem_> they are obscenely large

[14:36:16] <gregcnc> Flexure
[14:36:22] <anomynous> are they strong
[14:36:48] <pink_vampire> nema34?
[14:37:24] <pink_vampire> and you have to clean your nails with a brush.

[14:53:06] <joem_> pink_vampire, yeah n34
[14:53:22] <joem_> lol yeah i've been working in the garage
[14:53:35] <joem_> ok your nails are a lot nicer than mine
[14:53:52] <pink_vampire> now my nails muchhh longer.
[14:54:19] <joem_> those aren't short by any means
[14:54:19] <_methods> great for pickin your nose
[14:54:30] <_methods> you can get them buggers way up there
[14:54:36] <pink_vampire> _methods: NO!!!
[14:54:45] <joem_> sharpen one to a point
[14:54:46] <joem_> self defense
[14:54:54] <pink_vampire> NO!
[14:55:05] <pink_vampire> 17mm
[14:55:10] <joem_> really
[14:55:17] <pink_vampire> yes
[14:55:22] <joem_> seems long
[14:55:24] <_methods> long range booger getters
[14:55:31] <joem_> do you type with them?
[14:55:42] <joem_> and if so, is it noisy
[14:55:47] <joem_> satisfyingly so?
[14:55:58] <pink_vampire> I have CTS.. so anyway I'm using a pen and type sloow.
[14:56:04] <joem_> CTS?
[14:56:07] <joem_> some sort of disease?
[14:56:14] * joem_ will feel real bad if its actually a disease
[14:56:27] <pink_vampire> https://en.wikipedia.org/wiki/Carpal_tunnel_syndrome
[14:56:34] <joem_> chronic typing syndrome
[14:56:36] <joem_> ohhhhh
[14:56:37] <joem_> yeah
[14:56:44] <pink_vampire> yes,
[14:56:50] <joem_> you get that from typing with long ass nails :P
[14:57:14] <pink_vampire> maybe..
[14:58:19] <pink_vampire> I have it for years.. and only before 5 years I let my nails grow to so crazy length..
[14:58:34] <joem_> hey i'm a doctor and a firefighter and a 911 operator
[14:58:38] <joem_> (not really)
[14:59:01] <pink_vampire> the longest I ever had was 22mm
[14:59:15] <pink_vampire> LOL
[14:59:26] <joem_> i can't stand having long nails
[14:59:37] <joem_> even when they get a little long i have to trim them otherwise i'll have the urge to bite them off
[14:59:58] <pink_vampire> are you bite them?
[15:00:04] <joem_> not if they're trimed
[15:00:06] <joem_> trimmed
[15:00:40] <gregcnc> isn't that what 60 grit paper is for?
[15:00:56] <joem_> lol how thick are your nails
[15:01:03] <joem_> down there with the angle grinder
[15:01:39] <pink_vampire> OMG angle grinder O_O
[15:02:15] <joem_> texas chainsaw manicure
[15:02:23] <joem_> omg thats brilliant
[15:02:25] * joem_ writes it down
[15:02:41] <pink_vampire> LOL
[15:03:29] <pink_vampire> joem_: you make me laugh
[15:03:51] <joem_> wow and you haven't even seen a picture of me
[15:04:43] <pink_vampire> ok...
[15:04:59] <gregcnc> chainsaw manicure is an ongoing joke at my house. wife hates it when i tell her i have to get the chainsaw to clip her toe nails.
[15:05:21] <pink_vampire> now I'm now sure if I want to see..
[15:05:40] <joem_> eh, twas more of a joke
[15:05:47] <joem_> i just look like.... some guy
[15:05:59] <pink_vampire> gregcnc: what is going on over there..
[15:06:45] <pink_vampire> my phone die :(
[15:06:48] <gregcnc> it's not that bad, but she butchers them in like one minute
[15:07:13] <pink_vampire> TMI
[15:08:30] <joem_> i'm not sure if the driver is big or not, i've never used anything but itty bitty 2am SMD drivers
[15:09:41] <joem_> half of it is heatsink
[15:11:40] <CaptHindsight> I can't find a M19 x 1 tap in stock in the USA
[15:12:05] <gregcnc> can't CNC it?
[15:12:18] <_methods> x1?
[15:12:33] <_methods> that's not a common thread pitch for m19
[15:12:39] <JT-Shop> I have a M18 x 1 tap
[15:13:02] <CaptHindsight> ah hah drillsandcutters.com
[15:13:04] <_methods> http://www.sears.com/merlintools-19mm-x-1-metric-hss-right-hand/p-SPM11943411430
[15:13:16] <_methods> only $200 lol
[15:13:29] <CaptHindsight> $34
[15:13:51] <Simonious> all the tools fusion 360 is offering me are coming up metric, not seeing the toggle for standard - anybody know where it is?
[15:13:54] <_methods> where'd you find it?
[15:14:29] <CaptHindsight> https://drillsandcutters.com/m19-x-1-hss-metric-hand-tap/
[15:14:31] <Jymmm> M19x1.5
[15:14:58] <_methods> good price
[15:15:40] <_methods> wow their annular cutters are dirt cheap too
[15:15:53] <_methods> never heard of this company before
[15:16:11] <Jymmm> CaptHindsight: In stock too =)
[15:16:35] <Jymmm> New York
[15:17:03] <JT-Shop> dang F4 windshield for the BlueWing cost $355!
[15:17:09] <_methods> CaptHindsight: you ever buy from them before
[15:17:34] <enleth> I just connectet the bport's control to a genuine DEC VT520, they happily exchanged program code at a lightning speed of 2400 baud, the best this Heidenhain can do
[15:18:05] <Jymmm> enleth: 300 BAUD BABY!!!
[15:18:25] <enleth> the lowest it can do is 11, for punched tape punchers and readers
[15:18:37] <Jymmm> enleth: O_o lol
[15:19:03] <Jymmm> enleth: DO IT!!! I'd love to see tape/punch cards circa 2016 =)
[15:19:05] <Simonious> so.. I'm looking at the list of taps in fusion 360 and I've got no idea which one is for a 4-40 I would expect it to be labeled a such..
[15:19:16] <enleth> I have one too but it's a current loop teletype so it needs a converter
[15:19:33] <Jymmm> bah
[15:19:37] <Simonious> ahh, found it
[15:21:30] <enleth> and a keycode converter too - heidenhain talks V.24 and 7-bit ASCII, the teletype expects the actual Baudot code
[15:22:03] <Simonious> odd.. fusion 360 has tap mods of 'tapping' 'right tapping' 'left tapping' wonder what that first one is for..
[15:22:05] <enleth> but it's just a matter of time
[15:23:31] <enleth> Simonious: we have this joke in Poland: three trams approach a crossing. One goes left, another goes right and the last one follows them.
[15:25:31] <CaptHindsight> _methods: just did
[15:27:04] <Simonious> enleth: that works here
[15:27:50] <CaptHindsight> Enco doesn't even have it
[15:31:02] <_methods> yeah it's an odd thread pitch for that dia tap
[15:31:26] <CaptHindsight> ER16 nut size on a spindle
[15:31:50] <anomynous> woot
[15:31:54] <anomynous> i use those for drills
[15:32:00] <_methods> m19 by itself isn't a common dia metric tap
[15:32:30] <CaptHindsight> yeah, ER16 mini
[15:32:48] <CaptHindsight> cheap on ebay from China
[15:32:55] <_methods> at least according to iso 261
[15:32:58] <_methods> and 262
[15:33:55] <CaptHindsight> http://www.ebay.com/itm/New-19mm-19-x-1-Metric-HSS-Right-Hand-Tap-M19-x-1-0-Pitch-/161811423318
[15:34:07] <CaptHindsight> $13 shipped
[15:34:21] <_methods> well there ya go
[15:34:44] <CaptHindsight> unfortunately I need it by Friday, not April 3
[15:35:12] <_methods> i got some chinese taps and they were pretty damn bad
[15:35:19] <_methods> make sure you buy like 5 if you need 1
[15:35:45] <CaptHindsight> yeah, I only use them up to maybe 5mm
[15:35:51] <_methods> i'm willing to gamble on most chinese stuff
[15:35:57] <_methods> but i've been burned by a few things
[15:36:03] <_methods> chinese taps being one of those
[15:36:21] <CaptHindsight> tolerances are terrible
[15:36:31] <_methods> the teeth were so bad
[15:36:41] <_methods> it was actually comical until i broke the tap
[15:36:51] <_methods> then i wasn't laughin so much
[15:37:04] <Sync> I just buy good taps now, it is not worth breaking cheap ones off in valuable parts
[15:37:13] <_methods> yeah i just stick to OSG
[15:37:28] <_methods> but i was just tryin them out to see how they were
[15:37:37] <CaptHindsight> the cheapest I buy are Irwin
[15:37:51] <CaptHindsight> since they carry them at Menards
[15:37:55] <_methods> needless to say they weren't OSG quality lol
[15:38:35] <CaptHindsight> M19 in 6061 shouldn't be too bad
[15:38:44] <_methods> just sticky
[15:38:48] <_methods> you hand tapping?
[15:39:08] <CaptHindsight> for this yeah
[15:39:25] <_methods> you'll be fine with the cheap taps for that
[15:39:36] <_methods> i was tappin steel with my ghetto taps
[15:39:39] <_methods> didn't work so well
[15:39:50] <_methods> they would have been fine for alum
[15:39:55] <_methods> not rigid tapping of course
[15:40:01] <_methods> but good enough for hand tapping alum
[15:40:08] <CaptHindsight> for stainless I use the good stuff
[15:40:25] <CaptHindsight> I don't cut much steel
[15:40:33] <_methods> yeah i wouldn't even try them in SS unless you were just doing it for gigglez
[15:40:59] <CaptHindsight> 6xxx and 7xxx aluminum and SS is most of it
[15:41:36] <CaptHindsight> maybe some Invar
[15:42:23] <_methods> well if you order the chinese ones you'll see what you're dealing with when you get them lol
[15:42:49] <CaptHindsight> https://drillsandcutters.com/m19-x-1-hss-metric-hand-tap/ we'll see
[15:43:31] <_methods> i mean for that price you can't go wrong
[15:43:44] <_methods> how many collet nuts you making?
[15:44:27] <CaptHindsight> I'm actually making fixtures that attach to the spindle
[15:44:53] <_methods> how many fixtures you have to tap?
[15:45:01] <CaptHindsight> just a few
[15:45:08] <_methods> oh you'll be good
[15:45:37] <CaptHindsight> I never make more than a few of anything
[15:45:45] <_methods> i'd still order 2 since i know how my luck is with taps
[15:46:09] <CaptHindsight> anything past proto goes out to job shop
[15:46:13] <CaptHindsight> heh
[15:48:47] <CaptHindsight> mot made by Tap America
[15:49:28] <CaptHindsight> no name so hopefully GoodFu
[15:50:38] <CaptHindsight> RongFu is Taiwanese but not a great name for a brand
[15:50:39] <pink_vampire> https://drillsandcutters.com/1-hss-aircraft-taper-router/
[15:50:52] <pink_vampire> what is the use for that drill bit?
[15:51:52] <CaptHindsight> "Taper routers are used for cutting, trimming and routing around cowling, door sills and plexi-glass, trimming on wing terminals in bulkheads and ribs on fuselage."
[15:53:05] <pink_vampire> ok..

[16:02:04] <pink_vampire> joem_: ^
[16:02:56] <joem_> is that comfortable
[16:03:11] <pink_vampire> NO!
[16:03:19] <pink_vampire> I mean YES!!
[16:03:23] <joem_> lol
[16:05:45] <pink_vampire> joem_: let's say it that way.. I have to think about everything that I'm doing to keep them from break .
[16:06:25] <joem_> heh
[16:07:13] <pink_vampire> now.. think about metal working.. sharp corners, deburring, sanding etc..
[16:07:55] <pink_vampire> joem_: ^
[16:08:13] <joem_> yes
[16:08:16] <joem_> deburring nail
[16:08:22] <joem_> no need to have a deburring tool
[16:08:26] <pink_vampire> NOOOO!!!!
[16:08:30] <joem_> :P
[16:08:49] <pink_vampire> I'm grow them almost 1 year.
[16:09:04] <joem_> wow
[16:09:08] <pink_vampire> 11 months
[16:09:39] <joem_> i wish i could read chinese
[16:09:49] <pink_vampire> why??
[16:10:06] <joem_> manual that came with drivers has no english
[16:10:18] <pink_vampire> what driver?
[16:10:30] <joem_> https://i.imgur.com/BhHmYUs.jpg
[16:11:59] <pink_vampire> PU is the pulse Dr direction
[16:12:27] <pink_vampire> the negative of them go together,
[16:13:02] <pink_vampire> look
[16:13:03] <joem_> heh those aren't to difficult
[16:13:13] <joem_> the schematics shows that they are optoisolated, etc
[16:13:22] <joem_> i'm interested in the function of the display
[16:13:25] <pink_vampire> pend??
[16:13:37] <joem_> yep, interested in that output
[16:13:45] <joem_> p00 p001 p002, etc, what do the various menus mean and what are their settings
[16:13:54] <pink_vampire> alm?
[16:14:02] <joem_> alm, alarm
[16:14:14] <joem_> signal back to the controller when torque limits have been reached, crashes, over/undervolt, etc
[16:15:03] <pink_vampire> why do you buy stuff like that from china?
[16:15:28] <joem_> why not?
[16:15:52] <joem_> somebodys got to
[16:15:54] <joem_> :P
[16:17:40] <pink_vampire> I don't like to get electronic stuff from china
[16:19:15] <CaptHindsight> I get most of my non-critical life hangs in the balance can't hurt children and loose women women electronics from China
[16:19:49] <joem_> lol
[16:20:38] <joem_> my guess is that they all follow leadshine's example when it comes ot building this stuff
[16:20:45] <joem_> and that the same communication scheme is in place
[16:20:48] <joem_> its a place to start
[16:21:03] <joem_> of course, if their website is down....
[16:21:03] <joem_> wtf
[16:21:19] <CaptHindsight> or start there and remove parts and use cheaper parts until it stops working or customers notice
[16:23:39] <joem_> pink_vampire, ah, pend is on when the motor has yet to reach it's requested position
[16:23:42] <pink_vampire> what to you think about the G320X?
[16:24:18] <joem_> not bad, geckodrive makes good stuff obv
[16:24:22] <joem_> but, realize its not a closed loop controller
[16:24:49] <pink_vampire> what do you mean?
[16:25:43] <pink_vampire> you mean that the computer don't get the data from the encoders?
[16:25:49] <joem_> ok so, the geckodriver has a single pid controller and encoder on board, for potision management
[16:26:15] <joem_> the closed loop has three, for torque, position, and encoder
[16:27:02] <joem_> additionally, the geckodrive you m ust tune your pids, common for any digital servo driver
[16:27:12] <joem_> the more advanced ones will have a self tune routine
[16:29:18] <pink_vampire> I'm pretty ok with them I know it's not the best but for the price I think it's ok..
[16:30:49] <Deejay> gn8
[16:54:27] <enleth> _methods: once I was given a set of chinese taps that were just cast. that's it, no machining, raw casting. there were firggin' parting lines on them
[16:54:55] <enleth> I think they were the most blatantly chinese tools I've ever seen
[16:58:06] <enleth> to add insult to injury, they were suspiciously light and the surface had a spangle-like texture resembling zinc-based alloys
[16:58:38] <enleth> I'm pretty sure I did not try to put a magnet to them, unfortunately
[16:59:05] <enleth> although I didn not try to use them in general
[17:00:49] <_methods> yeah the chinese taps i had weren't quite that bad lol
[17:01:08] <_methods> but they were still bad enough to be basically worthless for anything besides aluinum or cast iron
[17:04:57] <Crom> installing freecad
[17:08:48] <enleth> BTW, do you keep a stock of manual tap sets, or just go for all machine taps and use them for manual tapping as well?
[17:09:27] <enleth> I do have quite a bit of manual straight taps, but I try to avoid buying more and get spiral machine taps when I need a new size
[17:09:31] <JT-Shop> what's manual tapping... oh wait I remember now
[17:10:10] <enleth> that's for when you have to tap a hole in the machine you normally use to tap holes
[17:11:00] <_methods> that really annoying activity you have to do when you don't have a machine with rigid tapping lol
[17:11:54] <Crom> hehe, I'm looking at the grizzly G9972Z. It looks like the first job you do is make a reversing lever for it
[17:12:20] <Crom> so you can cut left or right hand threads
[17:13:16] <enleth> on a related note, I'm considering buying some imperial keylocking thread inserts for the express purpose of repairing some stripped threads on the Bridgeport that someone re-tapped metric. as much as I hate the imperial threads, the only thing I hate more is imperial threads mixed willy-nilly with metric in the same machine
[17:13:45] <enleth> (and, as a consequence, imperial screw heads mixed with metric)
[17:14:43] <Sync> just replace everything with metric
[17:15:10] <enleth> I'd do that, but I'm not in the mood to disassemble the whole machine yet again
[17:15:33] <Sync> then ignore the imperial screws
[17:15:41] <Sync> and just replace them when you do it again
[17:15:47] <enleth> besides, I'd have to fit those inserts everywhere or seriously oversize all threads
[17:16:35] <enleth> it's hard to ignore them when some of them are used semi-regularily to access stuff
[17:16:45] <Crom> wooo 12x36 is also a gap bed
[17:18:43] <Sync> then replace them where you don't want them
[17:21:50] <enleth> nah, it's easier to fix the damage done and have just one type all over
[17:22:23] <enleth> and have spare parts fit without modification and stuff like that
[18:17:24] <Crom> hmmm Shars 250-105 I think I'll have to get one of those
[18:36:16] <[cube]> nice design: https://touchofmodern.insnw.net/products/000/386/686/a0fd50a8b908e6ba02973791e2519dd2_large.jpg?1455927565
[18:58:21] <witnit> IMO when ever possible use a roll/form tap in production work
[18:59:20] <witnit> shavings are hard to get out of the bottom of a blind tapped hole
[19:00:06] <Jymmm> just flood the hole with mercury ;)
[19:00:49] <witnit> wait, I dont understand that reference
[19:01:03] <witnit> haha explain pls
[19:02:10] <Jymmm> it was a joke
[19:02:35] <Tom_itx> hahahahahaha.... i got it!
[19:02:50] <Jymmm> Tom_itx: no you didnt!
[19:02:59] <Tom_itx> :)
[19:03:54] <Crom> pretty knife
[19:04:26] <Jymmm> Tom_itx: You ever work with OLED displays?
[19:05:14] <Tom_itx> not personally but i know a little about them
[19:05:36] <Tom_itx> i do know you must initialize them in the right order
[19:05:46] <Jymmm> Tom_itx: Does this look right? Seems "interlaced" http://imgur.com/yauh4ex
[19:05:47] <Tom_itx> or you could destroy em
[19:06:14] <Tom_itx> doesn't look that crisp to me
[19:06:16] <zeeshan-lab> :]
[19:06:28] <zeeshan-lab> what does
[19:06:35] <Tom_itx> evil mad scientist you are
[19:06:52] <malcom2073> lol
[19:07:08] <zeeshan-lab> got off work
[19:07:20] <zeeshan-lab> came to lab, have been blowing aluminum up
[19:07:39] <zeeshan-lab> pretty sure all the results i did over the last 6 months
[19:07:42] <zeeshan-lab> are bullshit
[19:07:52] <zeeshan-lab> cause im getting random failures with aluminum
[19:07:52] <Tom_itx> heck i knew that...
[19:07:56] <zeeshan-lab> which shouldnt be happening
[19:08:08] <zeeshan-lab> something wrong with the die or pressure controller
[19:08:17] <witnit> what kind of failure?
[19:08:19] * zeeshan-lab shoulda tried aluminum to begin with
[19:08:25] <zeeshan-lab> bulge test
[19:08:28] <Tom_itx> foil?
[19:08:30] <zeeshan-lab> ya
[19:08:34] <zeeshan-lab> i annealed it
[19:08:35] <zeeshan-lab> 1145
[19:08:39] <Tom_itx> maybe it's tempered from rolling
[19:08:42] <Tom_itx> never mind
[19:08:48] <witnit> tom....lel
[19:08:52] <zeeshan-lab> well i only tested the tempered material so far
[19:08:57] <zeeshan-lab> right now its running the first batch of annealed
[19:09:04] <zeeshan-lab> i hope it cracks at the pole. will make me happy
[19:10:33] <zeeshan-lab> i know something is wrong cause its taking more pressure to blow up the annealed material
[19:10:37] <Tom_itx> must be perfectly flat with no deformations in it
[19:10:41] <Tom_itx> or it will crack there
[19:10:45] <zeeshan-lab> ya
[19:12:05] <Tom_itx> i spent the afternoon forming parts on the screen
[19:12:43] <Tom_itx> and helping the flunkee that sits beside me
[19:13:04] <witnit> i bought lathe, and im no where near you thank you very much
[19:13:17] <Tom_itx> he's actually starting to get it a bit
[19:13:44] <Tom_itx> nice guy but not very pc savvy
[19:13:47] <witnit> if it werent for people in this room I wouldnt have any cncs at my shop (true story)
[19:13:50] <Tom_itx> he's an ole tool n die maker
[19:14:29] <Jymmm> Tom_itx: It looks like every other line is missing/blank
[19:14:43] <Tom_itx> the lace came unwoven
[19:17:51] <joem_> https://i.imgur.com/1ppffa8.png
[19:20:38] <zeeshan-lab> tom how old
[19:20:55] <Tom_itx> not sure if he's retired or not
[19:21:24] <Tom_itx> all he did was on manual machines
[19:22:18] <witnit> he can do everything we can, but he can do it in his head
[19:22:26] <witnit> thats what nice about those type
[19:24:34] <zeeshan-lab> =]
[19:26:31] <Tom_itx> meh, he may have a couple screws loose
[19:29:53] <witnit> You may see his eyes light up if you start saying things like, calculate the rise on that cam and make sure your clean your sine block, before you even think about picking that machinery's handbook up, here's your gauge blocks and trig tables.
[19:30:14] <witnit> should bring him back a few years
[19:46:30] <witnit> I bought an old clausing lathe today something like 3" bore hydraulic chuck
[19:48:02] <witnit> hopefully its still in descent shape, the guy said it just doesnt have alot of hours on it. but its ancient. Anyone have anything good to say about clausing lathes?
[19:48:34] <CaptHindsight> nice, nothing like an Emco
[19:50:03] <witnit> hmm, those look a little how do I say..
[19:50:11] <witnit> little
[19:52:40] <witnit> something similar to this but much older, bigger and dirtier. http://www.surplusrecord.com/listphotos/885509.jpg
[20:08:21] <zeeshan> nice witnit
[20:10:00] <Sync> hm, those single cable tig leads seem to be uncommon here
[20:15:54] <yasnak> Okay, so besides sublime with custom config what would be a good cnc program editor for multiple channels?
[20:16:22] <Tom_itx> multiple channels?
[20:18:07] <yasnak> yeah
[20:18:15] <Tom_itx> ahh that is kinda neat
[20:18:28] <yasnak> channel 1, channel 2, channel 3. all control different parts of the machine and use sync/wait codes
[20:18:33] <yasnak> swiss machines
[20:18:54] <Tom_itx> will it edit same name vars automatically?
[20:19:06] <Tom_itx> looking at the site
[20:19:25] <yasnak> what? sublime? its just an editor. has tons of plugins and packages
[20:19:30] <PetefromTn_> Congrats Witnit but I thought you were gonna buy my CNC lathe ;)
[20:20:00] <yasnak> I used to use pujr, but they license per computer $300.00 and everytime i need to reform its another. plus my laptop. annoying.
[20:20:11] <yasnak> And I can't use WinCNC due to lawsuits (yeah, i know)
[20:20:24] <Jymmm> PetefromTn_: s/buy/accept donated and delivered cnc/
[20:20:27] <witnit> PetefromTn_: this one cost $200 :)
[20:22:42] <PetefromTn_> hehe
[20:22:51] <PetefromTn_> you cheapass ;)
[20:22:53] <yasnak> http://www.star-m.jp/eng/products/lathe/la_pu.html i need that :( but don't want to pay again
[20:23:14] <Tom_itx> how hard is it to make a custom language file for sublime?
[20:23:17] <witnit> about 8 years ago I stopped in and handed him this BEI absolute encoder (nice resell value on it) told him I couldnt use it myself and I think he remembered me
[20:24:15] <yasnak> http://docs.sublimetext.info/en/latest/extensibility/syntaxdefs.html
[20:24:45] <Tom_itx> and what is the stuff on the right side of the screen?
[20:24:50] <PetefromTn_> I got everything to finish the CNC lathe build here...now all I need is a new house to put it in :D
[20:42:25] <witnit> yasnak: you mean you need a new license or just the program?
[21:11:38] <Erant> I received the 1000 line Omron encoder I bought from China for $20. It looks surprisingly legit.
[21:12:04] <Erant> I still think it's fake, but it's optical, and the line disc has "omron" on it.
[21:12:07] <Erant> Sooo. maybe?
[21:12:19] <Erant> We'll see if it actually works as a spindle encoder.
[21:14:56] <zeeshan> tons of omron fakes :P
[21:15:00] <zeeshan> damn chinese!q
[21:15:36] <Tom_itx> damn canucks
[21:18:06] <Erant> zeeshan: Yeah, but putting it on the optical disc? At least they're committed to the fake.
[21:18:21] <Erant> You can't see the optical disc unless you take off the cover and shine a light in.
[21:18:50] <Erant> It's just for a spindle encoder, so as long as it's even a little accurate, I'm cool.
[21:19:12] <Erant> Wonder if it's accurate enough for a rigid drag knife. :)
[21:26:49] <yasnak> witnit, new license
[21:27:23] <yasnak> I have the program, its on a trial. after 90 it closes up. i used to be able to break those by debugging them and following it to where it hid the key but no longer have time ;/
[21:47:09] <Sync> just use it in a vm
[21:51:12] <yasnak> ;/
[21:51:30] <yasnak> working on this text editor named atom
[22:38:23] <joem_> trying to control my machine from a beaglebone but not really finding a cape that provides 5v optoisolated high speed control of steppers + a few relays for spindle/flood/etc control + enough inputs to handle RPM, alarms from the motors, etc... something tells me this may not exist, and i shall need discreet relays, but otherwise, any suggestions?
[22:38:46] <joem_> here's this one, but not enough io pins have been made available http://www.probotix.com/wiki/index.php/PBX-BB
[22:38:51] <joem_> and no on-board relays
[23:58:38] <tiwake> pink_vampire: poke
