12:02 AM MacGalempsy: XXCoder. making chips now?
12:04 AM xxcodercnc: not today MacGalempsy
12:04 AM xxcodercnc: currently wiring spindle
12:08 AM MacGalempsy: must be exciting to get that much closer
12:09 AM xxcodercnc: yeah
12:09 AM xxcodercnc: no more stup[id grinmder
12:09 AM xxcodercnc: it sucked.
12:10 AM MacGalempsy: gonna need to see some pics
12:10 AM xxcodercnc: not yety
12:10 AM xxcodercnc: has old videos a sec
12:10 AM xxcodercnc: https://www.youtube.com/channel/UC9lTUoLDmMJkICEKVKdXj0A
12:11 AM xxcodercnc: nylon was a bad fail on my part LOL
12:28 AM MacGalempsy: doh!
12:28 AM xxcodercnc: yeah too mlong for no cooling system
12:29 AM xxcodercnc: well powerbox no smoke
12:29 AM xxcodercnc: now to wire rest up.
12:29 AM minibnz: still cant tapp a hole yet,but i have wired in the drawbar to the mesa and have added a gladevcp button that lets me open and close the chuck via software..
12:33 AM xxcodercnc: oikay stupuid questioon time
12:33 AM xxcodercnc: psu has "+v" and "com"
12:33 AM xxcodercnc: I assume com is ground?
12:34 AM MacGalempsy: yup
12:34 AM MacGalempsy: common
12:34 AM xxcodercnc: yeah
12:34 AM xxcodercnc: ok
12:41 AM xxcodercnc: board no smoke
12:45 AM xxcodercnc: `+
01:10 AM xxcodercnc: MacGalempsy: spindle works :)
01:11 AM xxcodercnc: just need to connect and figure out PWM
01:11 AM xxcodercnc: got no idea how configure that.
01:14 AM minibnz: xxcodercnc i can help you there...
01:14 AM xxcodercnc: thanks
01:14 AM xxcodercnc: whats pdm mode?
01:14 AM minibnz: just played that game and didnt loose
01:15 AM xxcodercnc: http://linuxcnc.org/docs/html/config/stepconf.html#_spindle_configuration
01:15 AM minibnz: pdm mode is for driving a servo i think
01:15 AM xxcodercnc: oh. mines a umm dc type so dont think thats useful
01:16 AM xxcodercnc: looks like I have to go to my computer to find out more information. a second
01:16 AM minibnz: mine is a DC motor too
01:17 AM minibnz: what would be useful is.. what control you have and what you have to connect the control to emc (just so i get what you are trying to do)
01:17 AM XXCoder: a second
01:17 AM minibnz: np
01:18 AM XXCoder: I hate how ebay deletes history
01:18 AM XXCoder: so I cant recover info after certain time
01:19 AM XXCoder: http://www.ebay.com/itm/301641324807?_trksid=p2060353.m2749.l2649
01:20 AM XXCoder: freq 1k to 10 khz
01:20 AM minibnz: ok this should be easy enough and what do you have on EMC's side? mesa parport?
01:20 AM XXCoder: BOB heh
01:21 AM XXCoder: it has pwm output
01:23 AM minibnz: yeah what BOB do you got.
01:23 AM XXCoder: oh lol a second
01:23 AM XXCoder: https://www.aliexpress.com/item/High-Quality-Upgraded-5-Axis-CNC-Breakout-Board-for-Stepper-Motor-Driver-Mach3-USB-Cable/32738646022.html
01:23 AM minibnz: ok so what i think you have is EMC on a PC with a printer port going to the BOB thats going to the spindle controller that goes to the motor :) ?
01:23 AM minibnz: do you have that wired up yet
01:23 AM XXCoder: only thing missing is wires from PWM output to PWM board
01:25 AM XXCoder: so
01:25 AM minibnz: ok i think you need to take the last two screw terminals on block nearest the usb port on the BOB.. they go to the PWM in on the spindle controller
01:26 AM XXCoder: I guess since range is 1k-10khz I can just select 5000 hz?
01:26 AM minibnz: yup
01:26 AM XXCoder: 0-10v I guess I can just use 18 awg?
01:26 AM minibnz: yuo
01:26 AM minibnz: yup
01:26 AM XXCoder: but what do I use for umm lemme bring up linuxcnc stepconf
01:27 AM XXCoder: "speed 1:" and 2, as wewll as pwm1 and pwm2
01:27 AM XXCoder: use spindle at speed
01:27 AM minibnz: if you select a lower pwm frequency it is less taxing on the parallel port so you will be able to do other things faster. unless you need really fine grain control i think1khz will be fine
01:27 AM XXCoder: cycles per revolution
01:27 AM XXCoder: 1k it is then
01:28 AM XXCoder: maybe little bit more like 1.5 khz dont like minium heh
01:28 AM XXCoder: http://linuxcnc.org/docs/html/config/stepconf.html#_spindle_configuration
01:29 AM minibnz: ok yeah mine runs at 3khz
01:29 AM minibnz: im on a mesa so its a lttle diff but did play with the par port.
01:29 AM minibnz: ok speed 1 speed 2 what do you mean is that the labels on the pins on the bob?
01:29 AM XXCoder: mine has minium of 2000 rpm (it can be slower but I guess just not enough power)
01:30 AM XXCoder: max of 12k
01:30 AM minibnz: sweet
01:31 AM XXCoder: yeah. I have tachmeter ready for later :)
01:31 AM XXCoder: I will 3d print mount for it later
01:32 AM XXCoder: going to my machine
01:32 AM minibnz: ok so on the speed controller board the green screw terminals whats the labels?
01:33 AM xxcodercnc: pwm and ground
01:34 AM minibnz: so just wire them to the matching terminals on the BOB.. then the rest should be in software.
01:35 AM xxcodercnc: yeah wiring is quite strightforward
01:35 AM minibnz: hal is where it gets fun
01:35 AM xxcodercnc: yeah
01:36 AM xxcodercnc: i gonna figure tachmeter wiring l;ater
01:37 AM minibnz: yeah i dont think the parallel port will be able to keep up with such a high spindle speed and a high resolution encoder. 1PPR might be all its good for
01:37 AM minibnz: this is for a router right? high spindle speeds?
01:39 AM xxcodercnc: yeah
01:41 AM minibnz: should still be useful even at 1PPR if you dont need the accuracy you could add a hardware divider that will help the parport keep up, very simple logic chip will do the job there.. you probably could divide the rpm by 12 and not really notice any loss in control
01:42 AM xxcodercnc: reappy? and keep power?
01:44 AM minibnz: sorry what do you mean?
01:44 AM xxcodercnc: keep the torque up
01:44 AM xxcodercnc: so it has cutting power
01:46 AM minibnz: yeah you can setup hal to widen up the pulses as the spindle speed drops due to chip load on a router it will be really useful due to its high spindle speed and variability
01:47 AM xxcodercnc: oh nice
01:47 AM xxcodercnc: hnmm spindle just powered on
01:47 AM xxcodercnc: estop wasnt released yet
01:47 AM minibnz: yeah that might be because the parport pins default the wrong way for that sort stuff.
01:49 AM minibnz: i have the same problem with my mesa card the misting fan and coolant pump turn on while linux is booting.. oh and its 100% duty cycle too so you can't use pwm to limit max power i was blowing up chips left right and center
01:49 AM xxcodercnc: i had set pwm to pin 1
01:50 AM xxcodercnc: hmmhow do i command it to stop
01:50 AM minibnz: but while its booting up your OS and linuxcnc the hardware sets the pin one way (probably high) this is read by the spindle controller as full speed
01:50 AM xxcodercnc: forgot gcode
01:50 AM minibnz: M5
01:50 AM xxcodercnc: no reaction
01:50 AM minibnz: M3 s0
01:50 AM minibnz: you might need to invert the par port pin
01:51 AM xxcodercnc: ya configuring it
01:51 AM minibnz: if its going when it should be stopped
01:52 AM * Loetmichel_ carries still an usb/rs485 adapter in his pocket... for 2 years now... the VFD is abpe to be controlled by rs485... I tried to do that for ages now... because i have the same problem: system boot: spindle running
01:52 AM xxcodercnc: yep minvert fixed it
01:52 AM Loetmichel_: until linuxCNC is started
01:53 AM Loetmichel_: also it would be handy tfor the S240000 command to have an actual effekt
01:53 AM minibnz: i have a hope pwc_home has offered to make custom firmware for the mesa card i have and first on my list is invert the coolant enable pins and the motor enable pins at boot up..
01:54 AM minibnz: you gotta solve that in hardware for the Parallel port...
01:55 AM Loetmichel_: minibnz: usually you can convince the VFD to start when it gets a low signal instead of a high
01:56 AM xxcodercnc: nice its doing full run test nw
01:56 AM xxcodercnc: including spindle
01:56 AM xxcodercnc: it started up to 10k rpm
01:57 AM xxcodercnc: no more lucious speed 27k rpm with runout from hell
01:57 AM minibnz: i have added a hardware switch inline for the misting fan and the pump so i dont get hosed too bad.. although sometimes i forget it.. it really should be fixed in the firmware so if i have a power outage the pump dont go crazy and flood me ot
01:57 AM Loetmichel_: XXCoder: btw: the chinese VFD and spindle bundle come with WAAAAAY to long ramps
01:57 AM minibnz: out
01:57 AM Loetmichel_: i have mine down to 1 sec start and 2 sec stop ramp
01:57 AM xxcodercnc: speed ramp up?
01:58 AM Loetmichel_: cant do 1/1 because then the VFD would go on Overvoltage when braking
01:58 AM Loetmichel_: yes
01:58 AM xxcodercnc: interesting dunno how long mine is on that
01:59 AM Loetmichel_: its useful if you have many starts/stops in the code
01:59 AM xxcodercnc: is pause for speedup configurable?
01:59 AM xxcodercnc: dont wanna it hit stock while still ramping up
01:59 AM minibnz: i had fun trying to tune my pid settings. i got lucky found a semi helpful blog and then played from there and it seems to work pretty good it overshoots at the moment but i think if i just tweak back the P value i will be good..
01:59 AM Loetmichel_: that was my problem
01:59 AM Loetmichel_: i use the Txx command to define depth of cut in my 2d files
02:00 AM Loetmichel_: which results in loads of m5 Txx m3 in close succession
02:00 AM xxcodercnc: mine dont seem to support ccw
02:00 AM minibnz: my problem was when i was setting it up the encoder cant go past 700rpm (dunno why just yet) but then the PID would get to full speed then i would hit the power and the fuse would blow
02:01 AM * Loetmichel_ once managed to blow a siemens micromaster completely
02:01 AM minibnz: i had to add a relay onto my mill to control direction. and had to add software delay when changing directions so the controller doesn't yellow light
02:02 AM Loetmichel_: ramped up a 1.1kw async motor to 24kRPM and then Estopped it
02:02 AM xxcodercnc: no rpm display
02:02 AM Loetmichel_: ... all fet modules let out the magic smoke:-(
02:02 AM Loetmichel_: so be careful when shortening the ramp down
02:03 AM xxcodercnc: is there a way to know commanded rpm?
02:03 AM xxcodercnc: if using mdi
02:03 AM minibnz: i was lucky it was just a fuse that was the first time i tried out my DIY VFD
02:03 AM xxcodercnc: err
02:03 AM xxcodercnc: manual
02:04 AM minibnz: use the hal-meter and look at spindle-rpm-cmd
02:04 AM xxcodercnc: how do i get that?
02:04 AM minibnz: machine menu hal-meter
02:04 AM xxcodercnc: looking
02:05 AM minibnz: then in the list that pops up on open the meter you can select signals and search for spindle, commnad the spindle from the MDI and see what variable has the same number then change the number and see if the meter changes
02:08 AM xxcodercnc: linuxcnc status seem to nhave that info too
02:08 AM xxcodercnc: i went over 12k rpm apparenrtly
02:08 AM xxcodercnc: was fraid to go too far so didnt go futher than 12300
02:09 AM minibnz: heheheh same here.. my motor goes up to 6k but the reduction is about 3:1 and i dont go near 2k anymore
02:10 AM minibnz: someday soon i might see if linuxcnc can handle auto spindle speed to feedrate.. once i get all the tool table and changer going..
02:10 AM xxcodercnc: so linuxcnc dont limit rpm?
02:10 AM xxcodercnc: can set s100000 and blow boards?
02:11 AM minibnz: oh i was tampering with hal directly looking at the pwmgen output and controls
02:12 AM xxcodercnc: m3 s12100 runs fine
02:12 AM minibnz: before i set any speeds i was just feeding the pwmgen directly sorta brute forcing it to see what i needed while i was making the pwm to analog converter
02:13 AM xxcodercnc: \so about divider
02:13 AM xxcodercnc: how do that work?
02:13 AM MacGalempsy: sorry got caught up in 1984
02:14 AM MacGalempsy: great news xxcodercnc
02:14 AM minibnz: its a logic chip that you take from your index pin as the input and it will divide by 2 4 8 or 16
02:14 AM minibnz: so it sits between the encoder and the BOB
02:15 AM minibnz: the encoder could just be a opto sensor or a hall sensor that gives you 1 pulse per revolution.
02:15 AM XXCoder: mac indeed
02:16 AM XXCoder: great now forgot why go to my room
02:16 AM XXCoder: ah yes getting phone to record run
02:16 AM minibnz: then in HAL you use a scale module to multiply the encoder rps value by what ever the hw divider is to get your real speed
02:16 AM XXCoder: mini yah got induction ready to wire in tachmeter
02:16 AM XXCoder: even comes with nifty display though limited to 9999
02:17 AM XXCoder: interesting
02:17 AM minibnz: oh if you want you could probably tamper with the display to read right too...
02:17 AM XXCoder: so say bob sends out 10v, it divides by 2 so 5v to PWM board
02:18 AM minibnz: you put a second divider that divides by 10 before it gets to the screen
02:18 AM minibnz: no wrong side of the equation
02:19 AM XXCoder: but isnt it still quite weak
02:19 AM minibnz: the bob sends out 0-10v to the spindle control encoded as a analog signal.
02:19 AM XXCoder: yeah
02:20 AM XXCoder: so bob sends 0-10v to PWM board
02:20 AM minibnz: yes
02:21 AM XXCoder: and divider lays beetween those?
02:21 AM minibnz: the encoder gives you 1ppr that goes to a hardware divider (made from logic chips) the divider then feeds back into your BOB as a input pin.
02:22 AM XXCoder: ppr = pulse per rev
02:22 AM minibnz: so if you think of it as a circle.. the signals from the GUI go out the PWM signal from the BOB to the spindle. then the encoder on the spindle goes to the divider then this goes into the BOB
02:23 AM minibnz: yes to ppr
02:24 AM XXCoder: im somewhat confused, divider between encoder and BOB means say if set 2k rpm and divider is 2, BOB gets 1k rpm data?
02:24 AM minibnz: correct.
02:24 AM XXCoder: isnt it mean it will ramp up to 4k rpm and think its going 2k rpm?
02:24 AM minibnz: thats in the feedback loop. then in the software of hal you multiply it back by 2 to get real rpm and no change in ramp
02:25 AM minibnz: what you are doing is to limit the speed of the signal on the parallel port.
02:25 AM XXCoder: ahh so it helps lessen signal demend
02:25 AM minibnz: you might find you dont need it and your hardware can keep up.. and you wont need to do all this..
02:25 AM minibnz: yes
02:26 AM minibnz: your CPU can multiply a signal way easier than it can count a 12khz signal
02:26 AM XXCoder: okay now it makes sense
02:26 AM XXCoder: thanks
02:27 AM XXCoder: I was thinking you meant divide rpm so it has more power at lower speeds
02:27 AM XXCoder: which kinda confused me
02:27 AM minibnz: oh no.. you are only controlling/tampering with the input/feedback
02:28 AM XXCoder: yeah clear to me now :)
02:28 AM Deejay: moin
02:28 AM XXCoder: though that made me wonder, is there a way? besides gearing heh
02:30 AM minibnz: thats all dependant on the type of motor you have and the controller. if you have a controller that pwm's the motor voltage then you pretty much have the best you are going to get short of going to a fully closed loop controller where the encoder connects to the controller not to EMC
02:31 AM minibnz: then you can get into brushless or AC motors its another deep dark rabbit hole.
02:31 AM XXCoder: yeah machine is rather limited
02:32 AM XXCoder: 52mm max
02:32 AM XXCoder: can do 43mm diameter
02:32 AM minibnz: thats pretty good, unless you are planning on doing huge things :D
02:33 AM XXCoder: yeah
02:33 AM XXCoder: if I build larger cnc router I'll go one of larger common sizes, like 57mm
02:33 AM XXCoder: those is lowest with vfd and ac spindle
02:34 AM minibnz: use it until you hit some limits then upgrades later wont be all that expensive.. i remember back i the day you wouldnt even think of using a brushless dc motor due to cost and complexity instead you just slapped in a bigger motor now its so easy to use a BLDC that will be my next upgrade after the toolchanger
02:35 AM XXCoder: I would love to have taper toolholders
02:35 AM XXCoder: so length is fixed for tools, dont have to find length each time change tool
02:35 AM XXCoder: just swap tools
02:35 AM minibnz: i got a set couple of tormach toolholders and then a lot of chinese clones :)
02:36 AM XXCoder: heh man machine at work has TIIIINY toolholder
02:36 AM XXCoder: TINY haas machine.
02:36 AM minibnz: i just wired in the power drawbar on my mill so it opens and closes automagically now..
02:37 AM XXCoder: man I love clickspring.
02:37 AM minibnz: pcb mills have indexable bits. there are collars you set onto the bare tools to set them all the same maybe you could do that? get a few common heights?
02:38 AM XXCoder: I suppose but small machine it dont really matter,
02:38 AM XXCoder: can always get tool setter
02:38 AM XXCoder: its not very hard
02:38 AM XXCoder: I has plenty pins for that.
02:38 AM minibnz: i am going to modify a axis scale into a tool setter.
02:39 AM XXCoder: https://www.youtube.com/watch?v=eb9J5a5eaWs
02:39 AM minibnz: i made a usb reader for the grizzly scales.. i dont use them at the moment they are all over the place after i smashed a houseing cuz it cost me travel in my y axis
02:48 AM XXCoder: usb reader for checking tool lengths?
02:48 AM minibnz: yeah
02:48 AM XXCoder: interestihng
02:49 AM minibnz: couple of ways i could do it.. easy way is to put it on the end of a usb PIC micro. have a button that fills out the tool table via usb keyboard device.
02:50 AM XXCoder: my biggest issue is cam stuff :(
02:50 AM minibnz: send value send tab send value send tab rinse repeat.. could also have a second sensor that detects the diameter of the tools :) keyboardless setup :)
02:50 AM XXCoder: I can design stuff but no idea how to make gcode of those.
02:50 AM minibnz: oh gcode is easy just dont try and learn it all at once.
02:51 AM XXCoder: heh its simple for me
02:51 AM minibnz: dxf2gcode will be your best friend for a while.
02:51 AM XXCoder: its basically like basic script language for me lol
02:51 AM minibnz: i use it for wierd shapes and then pluck the gcodes out and see how its done and why.. curves still beat me for the moment but i am getting better
02:52 AM XXCoder: g2 and g3 yeah
02:52 AM minibnz: oh so you mean creating the dxfs
02:52 AM XXCoder: nah
02:52 AM XXCoder: can always just use draft designing
02:52 AM minibnz: oh yeah use dxf2gcode to see one way to do it..
02:52 AM XXCoder: i didnt complete my manual machinist training so I cant figure what metal needs what rpm, ipm so on
02:53 AM XXCoder: and "bad cutting sound" dont really have any meaning to me as im deaf
02:53 AM minibnz: its good becuase you can break out individual shapes
02:53 AM MacGalempsy: another great clickspring video
02:53 AM minibnz: XXCoder there is a chart you can get that shows you which way you should router a board, inside outside endgrain and all that..
02:53 AM XXCoder: indeed!
02:54 AM minibnz: from there you can look at the shavings see how fine and hot they are..
02:54 AM XXCoder: yeah need to learn that
02:54 AM XXCoder: at work everything is basically given
02:55 AM minibnz: might not be a bad idea to get yourself a hand operated router so you can get an idea of what the vibes are like on some practice timber
02:56 AM minibnz: this is why i have kept all the handles on my mill. until i get my head around how to drive it sometimes i like to snap the first bit by hand to find its limits :)
03:00 AM minibnz: XXCoder do you have access to a oscilloscope?
03:00 AM XXCoder: unfortunately nope
03:00 AM minibnz: can you code?
03:00 AM XXCoder: kinda of, been a while lol
03:01 AM minibnz: arduino and maybe a bit of GKT
03:01 AM minibnz: QT sorry
03:02 AM minibnz: maybe you could hook up a accelerometer upto the router head and display the vibrations on a screen or a set of leds with an arduino?
03:03 AM XXCoder: thats not too bad idea
03:04 AM minibnz: a mega could probably be turned into a spectrum analyser and you could feed that with a peizo pickup.. that could be a fund little project
03:04 AM XXCoder: tachmeter would also tell me if its trying to cut too much as stalling
03:04 AM minibnz: a mega could probably do a single fft and a lcd pretty easy
03:05 AM minibnz: oh once you have the hardware getting a tach on the screen should be pretty easy with the stepconf alone
03:05 AM SpeedEvil: ESP8266 has wifi, I2S in, for high quality audio, and a 160MHz 32 bit processo, for about $2 in modules
03:05 AM minibnz: the pconf almost got my spindle speed right..
03:05 AM XXCoder: heh I have physical tach display too
03:06 AM minibnz: yes watching the tach drop as it hits the work peice will be good
03:07 AM XXCoder: indeed though since its limited to 9999 if its at 12000 it wouldnt show loss till below that
03:07 AM XXCoder: if it goes below its in trouble anyway
03:07 AM XXCoder: so not too big problem since mostly wood and some alum
03:08 AM SpeedEvil: It would be nice if tool force were easier to directly measure
03:08 AM minibnz: you could put a hardware divider on that so it goes in steps of 10..
03:08 AM XXCoder: ya divider would work that way also
03:08 AM XXCoder: just need to remember to add 0 at end lol
03:08 AM minibnz: maybe there is ajumper inside you can adjust?
03:09 AM XXCoder: nah pure 0-9999
03:09 AM XXCoder: theres variants that add . if its over 9999 so say for 12000 it would say 1.200
03:09 AM XXCoder: but mine is cheaper version that doesnt.
03:12 AM XXCoder: okay done watching nilered video going to record a test run and uplaod to youtube.
03:13 AM minibnz: so if you want to divide by 10 you could use a 4017 chip.. feed the 1ppr into the input the 10 output pin to your par port and also the the 4017 reset pin add power and you are away..
03:15 AM minibnz: woops not the par port you feed the 10output pin to the reset and to the hardware counter dusplay input
03:19 AM XXCoder: back
03:20 AM XXCoder: well it looked good
03:20 AM XXCoder: dunno on sounds thats why i recorded a video
03:20 AM XXCoder: working on that now.
03:21 AM minibnz: well as long as the finish is nice no splinters or dags, and the machine is not shaking like mad and it has not burned the wood your settings are probably good.
03:21 AM minibnz: doh.
03:21 AM XXCoder: its not cutting anything just dry run
03:21 AM XXCoder: so you guys can joy it making nasty noises lol
03:21 AM XXCoder: *enjoy
03:21 AM minibnz: ahh sweet
03:21 AM minibnz: im in for that :)
03:22 AM minibnz: too slow a feed rate and you burn your job piece..
03:22 AM minibnz: to fast and the chips are more like splinters and it will vibrate a bit
03:26 AM XXCoder: https://youtu.be/1JMSRF6Q9uw
03:27 AM XXCoder: sorry shaky dont have any holder
03:28 AM minibnz: thats pretty sweet...
03:28 AM XXCoder: you can see old setup there from failed nylon run LOL
03:28 AM XXCoder: its been 9 months
03:28 AM XXCoder: sounds good?
03:29 AM XXCoder: nylon https://www.youtube.com/watch?v=sojJgCfDbp4 heh
03:30 AM XXCoder: its also one and only time I played with transitions. yeah I didnt like it lol
03:31 AM minibnz: the nylon video i can suggest why you failed... you need to get an aircompressor to blow on the cutter like coolant but air
03:31 AM minibnz: also far too fast for nylon.
03:31 AM XXCoder: yeah and need pauses to cool off if nothing else
03:31 AM XXCoder: well i have 16 more of those pucks
03:31 AM XXCoder: so it dont really matter
03:32 AM minibnz: but if you add air you are going to make a massive mess..
03:32 AM minibnz: i have coolant and it works well to keep the cutter clean
03:33 AM minibnz: just got the fan running for my misting setup, just have to work out how im going to get the air from the fan to have a little coolant in it and onto the tool
03:34 AM XXCoder: http://s3.crackedcdn.com/phpimages/photoshop/6/3/8/508638_v1.jpg
03:34 AM XXCoder: jan birthday lol
03:34 AM minibnz: fun fact :)
03:35 AM minibnz: betya that gets ya all the gals..
03:37 AM minibnz: i reckon its right up there with wanna watch me suck a spaghetti up one nostril and out the other..
03:37 AM XXCoder: lol
03:37 AM minibnz:
03:38 AM XXCoder: http://cubiclebot.com/wp-content/uploads/2013/02/157-448x600.jpg?cb5e28 heh
03:38 AM minibnz: the other problem with cutting plastics at those speeds is that it will swell, as it heats up it swells into the cutter and more plastic gets removed when it cools it shrinks
03:39 AM minibnz: hahahahaha
03:39 AM XXCoder: yeah at work we use shitton of coolant on nylons
03:39 AM minibnz: hahahah
03:39 AM minibnz: hahah
03:39 AM XXCoder: those pucks I have is left over from one job
03:39 AM minibnz: nice.. i like to re-appropriate scraps and leftovers at work too...
03:40 AM XXCoder: yeah only if its literal trash though
03:40 AM minibnz: we have boxes of terminal blocks and pins and switches from stuff we have saved..
03:40 AM XXCoder: I'm still waiting gor good brass leftovers so I can make brass hammer with alum middle
03:41 AM minibnz: these are things that are worth money and dont take up much space so we keep them in containers at work but if we need them then they are free to a good home..
03:42 AM minibnz: a supplier sent us 1600 of the wrong type of screw they are not in our BOM our warehouse chick gave em to me and the old block to do what ever we want with them.. she couldn't bring herself to just toss'em
03:42 AM XXCoder: douchebags. https://www.youtube.com/watch?v=DJOX0c60wQE they burnt rug and play on rug that looked to be decent condition
03:42 AM XXCoder: wow lucky ya
03:44 AM minibnz: and i try to make it even i take random things in to work that i have here.. like i pulled the spot light off my 4wd so they could see the light pattern thru their camera before they bought 6 of them. saved them about a week.. thats worth way more than all the screws and components that i could ever 'pocket' and walk' out with
03:44 AM XXCoder: nice
03:44 AM XXCoder: indeed. as lonmg as stuff dont "walk out"
03:44 AM XXCoder: have persmissions and such
03:45 AM XXCoder: uhh those douchebags is melting zinc coated bolt
03:45 AM XXCoder: they might get themselves zinc fever
03:45 AM XXCoder: flipping morons one guy almost touched other pole wire when remocing metal chunk from one
03:45 AM XXCoder: he'd have died
03:46 AM minibnz: oh yeah i always tell them what i wants.. and make sure they dont need them..
03:49 AM XXCoder: nice
03:50 AM minibnz: sometimes they have said just thow xyz out and i have taken it home, then a few weeks later they are like spewin we tossed them go order more... and i tell them and bring them back
03:51 AM XXCoder: dont company you work for know what they need? lol
03:51 AM minibnz: yeah and no..
03:52 AM XXCoder: ewhats they and you do
03:53 AM XXCoder: oh yea
03:53 AM XXCoder: my video, machine sounds good? no nasty stepper resourances?
03:54 AM minibnz: things change.. and since the sydney office closed at my old day job all these things i have collected have become very handy now i am working from home.. i dont mind charging them what i think is a great rate. plus all the prior knowledge i have as well that makes me feel i could probably charge more but meh im happy for now..
03:54 AM minibnz: no the stepper axis all sounded really nice..
03:54 AM XXCoder: so worth the upgrade, even though tb6560 never saw any real use
03:56 AM minibnz: i wonder if a old hifi spectrum analyser might help you out with that sort of thing, seeing as though you are looking for (normally) audible frequencies, might be a simple tool for you slap that in a box take to work see how the 'perfect' machines 'sound' and go home and see if you can get the same thing..
03:57 AM XXCoder: yeah
03:57 AM minibnz: yeah i run tb6560's and the noise is horrible.. and i think its to do with the decay settings, i need to have them in the noisy horrible setting to be able to get my max speeds out of them
03:57 AM XXCoder: heh had horrble settings for tb6560
03:58 AM XXCoder: 50 decay I think
03:58 AM minibnz: microphone + pre-amp -> spec'y
03:58 AM XXCoder: it was mostly reasonable (watch "tuned" video)
03:58 AM XXCoder: but still sucked
03:59 AM minibnz: other than the noise its ok, when i am booting up my Z axis makes random steps (nearly snapped my tap like that) and today i notice that there is a few electro caps that are leaking on the Z circuit so i think i will be replacing them and seeing whats going on..
04:00 AM XXCoder: leaky caps l;eak magic smoke
04:00 AM minibnz: little brown stains under their legs makes them look like they have shat themselves...
04:01 AM minibnz: once they leak all their goodness then the smoke comes out....
04:01 AM XXCoder: fancy
04:02 AM minibnz: i think its partly due to they are only 25v and i am running 24v so they might be on the edge,, i have no idea if they see the 24v rail but meh i will install higher voltage onese...
04:02 AM minibnz: oh you gotta clean the brown stain up too.. cuz if you leave it there it will eat the tracks away and then you will be in trouble..
04:04 AM XXCoder: ouch
04:04 AM XXCoder: yeah time to upgrade heh
04:04 AM minibnz: had a job years ago trying to keep the scraps of the old telephone exchange boards alive while they completed an upgrade.. it had me grinding out burnt pcb and refilling it with 2pt epoxy then replacing the tracks with wires...
04:04 AM XXCoder: my cnc royter system is 24
04:04 AM XXCoder: 24v
04:04 AM XXCoder: sounds fun ugh
04:04 AM minibnz: i will replace them.. they are cheap :) and i have some 63v ones here somewhere..
04:05 AM minibnz: the company got good coin for that job. and the boss pissed it away on crap..
04:05 AM minibnz: i was billing 40k a month for just what i was doign
04:06 AM XXCoder: one month is more than my annual income assuming usd is same value
04:06 AM minibnz: i know i was only getting 3500/month at that job..
04:07 AM XXCoder: heh I still remember that one day
04:07 AM XXCoder: I made 660 parts in one day
04:07 AM XXCoder: one is 75 bucks.
04:07 AM minibnz: fair enough they have a few other expenses other than me but still... there was other contracts that i worked on too..
04:07 AM XXCoder: no no its titanium type
04:07 AM XXCoder: 150 bucks
04:08 AM XXCoder: 2 of em woild have went well over what I earned that day.
04:08 AM XXCoder: so 660 yeah lol
04:08 AM minibnz: but the theory is that the machines might not be in use 100
04:08 AM minibnz: 100% of the time.. :)
04:10 AM XXCoder: actually most of production machines is in fairly constant use
04:10 AM XXCoder: only new machines is still being configured so not really running a lot.
04:10 AM XXCoder: 11 machines from sister company that went under
04:11 AM minibnz: oh i know thats the reality but thats not how they think when billing time comes about.. unless you have so much work that your job is slowing down other jobs :)
04:12 AM XXCoder: heh that happened
04:12 AM XXCoder: company got new infinity parts job that took over old cell
04:13 AM XXCoder: so some of jobs had delayed and was quite late when we moved em to different machines
04:13 AM XXCoder: I run the new cell, other guy run the old cell
04:13 AM XXCoder: any others run standalone cnc machines
04:13 AM XXCoder: *and
04:14 AM minibnz: most times i have seen that happen in electronics the old manufacturer and the new one get together and sort out the wrinkles in the handover.. its quite civil.. in metal work its start from scratch the other guy dont know what he is doing sort of thing
04:15 AM XXCoder: heh we didnt have that benefit :(
04:15 AM XXCoder: sister company that went under was at Utah
04:15 AM XXCoder: company i work is at washington
04:15 AM XXCoder: so theres only 2 left now, one at washington and one at calfornia
04:15 AM minibnz: well in electronics the machines and files are pretty much all standardised
04:16 AM minibnz: relativley new sorta trade/industry.. at least compared to sheet metal work.
04:17 AM XXCoder: heh one I work for have so many different machines
04:17 AM XXCoder: from haas to okuma
04:17 AM XXCoder: a61 is one I run
04:17 AM XXCoder: companies tend to standardize one one brand so programs is more sharable
05:11 AM jthornton: morning
05:12 AM XXCoder: hey jthornton https://www.youtube.com/watch?v=1JMSRF6Q9uw
05:12 AM XXCoder: omg a new video lol bveen months :P
05:14 AM jthornton: it moves!
05:14 AM XXCoder: and spins!
05:15 AM XXCoder: real spindle works :)
05:15 AM XXCoder: its so silent compared to grinder
05:16 AM XXCoder: I dont really feel anything when its dry running
05:17 AM jthornton: just watched it again with my speaker on and it sounds good to me
05:18 AM XXCoder: nice
06:12 AM XXCoder: https://www.youtube.com/watch?v=Mi75y7DevjQ
06:13 AM XXCoder: fanastic. classic myfordboy, but with new stuff like cnc
06:13 AM XXCoder: he cast and milled new holder for spindle
06:29 AM sync_: meh all those spindles are crap
06:30 AM XXCoder: heh better than orginial machine had
06:30 AM XXCoder: check out mine https://www.youtube.com/watch?v=1JMSRF6Q9uw lol
06:30 AM XXCoder: spindle there is a upgrade from really bad grinder
06:33 AM sync_: I wouldn't be so sure, an acceptable grinder at least is designed for the load
06:33 AM XXCoder: heh grinder runout was... insane
06:33 AM XXCoder: it was really loud, so it couldnt work well
06:34 AM sync_: wat
06:35 AM sync_: since when has noise something to do with performance?
06:35 AM XXCoder: it vibrates so hard it didnt cut smoothlyu
06:35 AM XXCoder: remember, "loud" to me means it vibrates so hard
06:35 AM XXCoder: it can be really loud but silent vibration wise lol
06:36 AM XXCoder: I wouldnt know if that happened
06:37 AM XXCoder: anyway grinder was cheap shit
06:38 AM XXCoder: 27k rpm only, and like I menioned, really bad runout lol
06:39 AM sync_: I'd just have gotten a better grinder, the collet adapter on the spindle is a joke
06:39 AM XXCoder: or stright router, if theres any 43mm lol
06:48 AM XXCoder: hmm
06:48 AM XXCoder: I wonder if using 2020 to make box for electrics would work,
07:10 AM XXCoder: elio apparently will have 120 amp alternator
07:10 AM XXCoder: whats "standard" alternator amps?
07:12 AM archivist: there is no standard
07:12 AM XXCoder: thats why i added quotes
07:12 AM XXCoder: average car usually has what amps?
07:13 AM archivist: power station alternator is in many thousands of amps and volts
07:13 AM sync_: 120 is a bit on the low side
07:14 AM sync_: on higher end cars it is not uncommon to see 250A
07:14 AM XXCoder: interesting
07:14 AM XXCoder: not too surpising as its quite small autocycle.
07:17 AM R2E4_bevins: Any ideas on lube control? Setting a time to run a lube cycle? I know there was a thread in the forums about adding time to iocontrol lube but I cannot find it.
07:20 AM jthornton: I do it in classicladder using a motion pin
07:21 AM R2E4_bevins: How much time between cycles?
07:21 AM sync_: I'd do something between 10 and 30 minutes
07:21 AM sync_: if you do short travel work, even more frequent
07:23 AM jthornton: I don't recall but the time was in the manual so I just copied it
07:23 AM R2E4_bevins: OK but its not lube oil, it is grease, I dont think that matters but I will check. It is overhead linear bearings so lube oil would drip on table and pieces...
07:23 AM R2E4_bevins: JT-Shop: I noticed you have it on your site. I'll look at that.
07:24 AM R2E4_bevins: or a post one of the two.
07:24 AM sync_: depending on your travel speed you may want oil
07:25 AM archivist: and dont over lubricate
07:26 AM sync_: pushing more oil than you need doesn't really hurt anything
07:26 AM R2E4_bevins: The manual says dont use oil. It has a specific grease, mobil ep0
07:26 AM sync_: with grease you can put in too much
07:26 AM R2E4_bevins: I have a centralized distributor, I give it a pulse and it delivers a specific amount.
07:27 AM archivist: it costs money over lubricating
07:27 AM R2E4_bevins: But I do not know what the original control did....
07:27 AM sync_: less than a broken machine archivist
07:27 AM archivist: blown seals and wastage
07:28 AM sync_: look up what the rail manufacturer says
07:28 AM sync_: but probably not very often
07:29 AM sync_: even if I push a liter a day or more, it is not really a cost factor and ime lube oil will not blow out seals, grease might
07:29 AM R2E4_bevins: A liter a day? on one machine?
07:30 AM sync_: yeah
07:30 AM sync_: why not?
07:31 AM R2E4_bevins: On my VMC it drops in a tray. I'd be changing it out everyday. I dont use it much but still.
07:31 AM Loetmichel: harhar... just wanted to start my "tinkerPc"... THAT thing wasnt on for a (to) LOOOONG time... couldnt find the mouse because even pulling its cable did nothing, mouse has disappeared under a SO big pile of junk that i will rip the cable out instead of pulling ot out of the pile...
07:31 AM sync_: if I'm doing work with a lot of short moves I lube often
07:31 AM sync_: as the lube tends to get pushed out and not distribute properly doing that
07:31 AM sync_: and it is cheap insurance
07:32 AM sync_: a liter of castrol magna is 2.5€ or something...
07:32 AM R2E4_bevins: my lube distributor on my VMC, I add power and it automatically distributes it, I get an alarm when it is low, I think it pumps every 1/2 hour
07:32 AM XXCoder: whats you use to lube machine?
07:33 AM sync_: I use any cglp 68 or 220 that my oil dealer has on sale
07:33 AM R2E4_bevins: I use lubriway ISO68
07:33 AM XXCoder: how do you lube runways and ballscrew?
07:34 AM XXCoder: currently my cnc router has nothing on rods and ballscrew has unknown grease
07:34 AM sync_: through the lube line and the lube pump
07:34 AM sync_: I would use a cglp 220 if your stuff is exposed
07:34 AM sync_: the higher viscosity will make it stay longer
07:34 AM XXCoder: hmm ok
07:34 AM R2E4_bevins: Mine is all sealed.
07:35 AM XXCoder: cglp 220 seems euro and that region only
07:35 AM sync_: it is just a classification of oil
07:35 AM R2E4_bevins: drips in a pan on the Y and Z, dont know where it goes from the X....lol
07:35 AM XXCoder: ah so thats regional classification, wonder what it is in usa classification
07:35 AM sync_: vactra no 4 would be a cglp220
07:36 AM XXCoder: https://www.amazon.com/MOBIL-Vactra174-Way-Lubricants-VACTRA/dp/B00065UK2C
07:36 AM XXCoder: bucket for 112 bucks
07:36 AM XXCoder: so not very expensive. just whole bucket yeah gonna look for smaller :)
07:37 AM XXCoder: oh wrong one, found another. 158 bucks for bucket
07:37 AM R2E4_bevins: JT-Shop: https://forum.linuxcnc.org/20-g-code/30998-m7-m8-g-codes#74976 This what your talking baout?
07:38 AM R2E4_bevins: Is the Oiler output in CL your out-07?
07:38 AM XXCoder: https://www.mscdirect.com/product/details/60002177
07:39 AM jthornton: yea that's what I use
07:40 AM jthornton: I'm down in the beer cave :)
07:40 AM R2E4_bevins: JT-Shop: Thats usually not a problem at 08:33 AM....
07:41 AM XXCoder: it will probably take my cnc router 100 years to use 5 galloon lol
07:41 AM R2E4_bevins: down on inventory?
07:41 AM XXCoder: 5 am, time to fake being dead for 7 hour approx. laters
07:42 AM jthornton: no beer down here just some wine that is clarifying
07:42 AM jthornton: later
07:46 AM Loetmichel: XXCoder: $me went to bed at 0900 this morning... and awoke at 1200, two hours ago...
07:46 AM Loetmichel: i just hope my inner clock will work on monday when i have to wake up at 0800 ;)
07:46 AM Loetmichel: 0700
08:32 AM os1r1s: Where is the default tool change location set in linuxcnc?
08:40 AM R2E4_bevins: In the ini file
08:43 AM Tom_itx is now known as Tom_L
08:43 AM R2E4_bevins: In the EMCIO section tool_change_position
08:46 AM os1r1s: R2E4_bevins Awesome. Thanks. Do you happen to know if it uses world or fixture coordinates?
08:50 AM R2E4_bevins: oslrls: I dont kniow. I think you have to spcecify with G?? Not sure
08:53 AM R2E4_bevins: Absolute
08:54 AM R2E4_bevins: But you might want to verify....
11:25 AM ApocalypseCow is now known as insomnia
11:49 AM zeeshan: blah
11:49 AM zeeshan: looks like after all this months of back and forth for getting a hydraulic pump gasket
11:49 AM zeeshan: they dont have a replacement gasket :(
11:50 AM sync_: silicone the shit out of it
11:51 AM archivist: make one, brown paper and grease it
11:52 AM zeeshan: if it were that easy
11:52 AM zeeshan: i'd have done it a long time ago :P
11:52 AM zeeshan: http://i.imgur.com/hwysxNT.jpg
11:52 AM archivist: it generally is :)
11:52 AM zeeshan: it's the gasket that goes in between the two chambers that are at the highest pressure
11:52 AM zeeshan: around 1ksi
11:52 AM sync_: then use a sheet of copper
11:53 AM zeeshan: the oem gasket is a metal gasket with embossing coated with nitrile rubber
11:53 AM zeeshan: its a POS compact design
11:53 AM zeeshan: so you need that damn embossing to seal for a damn.
11:54 AM zeeshan: at leas tthey tried
11:54 AM zeeshan: they sent me 8 different gaskets
11:54 AM zeeshan: lol
11:54 AM sync_: I bet a piece of copper with hylomar on it would seal just fine
11:55 AM zeeshan: i think hylomar contaminates hydraulic fluid
11:56 AM archivist: machine a groove for an o ring
11:56 AM sync_: with what?
11:56 AM zeeshan: archivist
11:56 AM zeeshan: i was actually thinking that
11:56 AM sync_: it is just PU rubber iirc
11:56 AM zeeshan: you think i can get away with a viton or nitrile rubber seal?
11:56 AM zeeshan: :)
11:56 AM archivist: look at the o ring specs
11:56 AM zeeshan: http://i.imgur.com/z9nJXoh.jpg
11:57 AM zeeshan: i got a book here
11:57 AM Wolf_: bubblegum
11:57 AM zeeshan: it talks about high pressure sealing
11:57 AM sync_: yeah just smear hylomar on it and be done
11:57 AM zeeshan: might work in this case
11:57 AM sync_: common repair on agricultural shit
11:57 AM zeeshan: sync_: this my cnc lathe's hydraulic pump
11:57 AM zeeshan: the last thing i want is this thing leaking in the middle of a job
11:57 AM sync_: sure
11:57 AM sync_: but it won't
11:58 AM archivist: that gasket goo works well
11:58 AM zeeshan: so youre saying
11:58 AM zeeshan: just hylomar it
11:58 AM sync_: ah, the obvious answer is, scrape it oiltight
11:58 AM zeeshan: directly on the surface
11:58 AM sync_: yeah
11:59 AM zeeshan: rofl @ scrape it oil tight
12:00 PM archivist: we used to run the bikes with goo instead of gaskets, stayed oil tight then
12:02 PM zeeshan: https://www.garlock.com/en/products/blue-gard-style-3000
12:02 PM zeeshan: i was thinking of just cutting a gasket out of this
12:02 PM zeeshan: material
12:04 PM archivist: damned off claim "drastically lowers emissions levels"
12:04 PM archivist: odd
12:05 PM archivist: look at max pressure
12:05 PM sync_: as I said zeeshan, there are probably a lot of solutions
12:05 PM sync_: hylomar will work, an annealed sheet of copper will also
12:17 PM zeeshan: sync have you heard of the knife maker "puma"
12:17 PM zeeshan: they're apparently make knives in germany :)
12:31 PM Tom_L: zeeshan, what's up?
12:32 PM Tom_L: seems you keep making things harder on yourself
12:32 PM zeeshan: ordering gasket material
12:32 PM zeeshan: how so
12:32 PM zeeshan: i tried ordering the right gasket from the manufacturer
12:32 PM zeeshan: and they gave me the wrong gasket 8 times
12:32 PM Tom_L: was that pump working?
12:32 PM zeeshan: now i have to make my own gasket
12:32 PM zeeshan: yep
12:32 PM Tom_L: is that pump working?
12:32 PM zeeshan: but it was leaking
12:33 PM Tom_L: brittish cars run with leaks
12:33 PM Tom_L: new
12:33 PM zeeshan: This lathe rebuild
12:33 PM Tom_L: i know
12:33 PM zeeshan: will likely be a pain in the ass
12:33 PM zeeshan: m,ainly because parts are a bitch to get.
12:34 PM Tom_L: not off to a good start for sure
12:34 PM zeeshan: at least the computer and mesa hardware is ready
12:34 PM zeeshan: :)
12:36 PM Tom_L: been fighting printer ports here
12:36 PM Tom_L: trying to keep an old dos app running
12:38 PM zeeshan: hehe
12:38 PM zeeshan: im about to drill a hole in my firesteel rod
12:38 PM Tom_L: it's the last hurdle
12:38 PM zeeshan: to pass some paracord through
12:38 PM zeeshan: i think i should video it
12:38 PM zeeshan: what old dos app are you running
12:38 PM zeeshan: and why!@?!?!
12:39 PM Tom_L: a business app i wrote years ago
12:39 PM Tom_L: don't wanna rewrite it in windows
12:39 PM Tom_L: taking the easiest way i can find right now
12:39 PM * zeeshan hands you a 486
12:39 PM Tom_L: the old pc is starting to flake out
12:39 PM Tom_L: i'd take it
12:39 PM Tom_L: this is a p100
12:40 PM Tom_L: i've got much newer boards with blown caps

01:24 PM zeeshan: :D
01:34 PM os1r1s: F/S question. On a g0704 size mill and a 3/8" end alum roughing end mill, do you think .125 DOC with .125 stepover. What feed would you use at 2250 RPM? Cutting 6061.
01:34 PM zeeshan: os1r1s: is it cnc
01:35 PM os1r1s: zeeshan Yep. Using fusion360 for cam
01:35 PM zeeshan: how many flutes on the end mill
01:35 PM zeeshan: feed = rpm * number of cutting edges(flutes) * chipload (in inches per tooth)
01:36 PM zeeshan: so if its a 3 flute end mill, you a pretty safe chip load is .001"/tooth
01:36 PM os1r1s: 3 flutes on the end mill Carbide with ticn coating
01:36 PM os1r1s: No coolant
01:36 PM zeeshan: 2250*3*.001
01:37 PM os1r1s: 67.5?
01:37 PM os1r1s: ipm
01:37 PM zeeshan: 6.75
01:37 PM zeeshan: hehe
01:37 PM zeeshan: you can go a lot faster than that
01:37 PM zeeshan: prolly around 18"/min would be ok
01:38 PM os1r1s: I'm actually at 6.75 right now
01:38 PM os1r1s: But I'm trying to figure it out
01:38 PM os1r1s: I've already broken 2 bits this weekend (on other parts). So I'm trying to be more safe :)
01:38 PM zeeshan: the problem is
01:38 PM zeeshan: if you dont use any coolant
01:38 PM zeeshan: or some sort of mist
01:38 PM os1r1s: I dont' yet. I still need to add it
01:38 PM zeeshan: 6061 will gum up even a 3 flute end milkl
01:38 PM zeeshan: when you try to feed faster
01:39 PM zeeshan: you can spray wd40 while its cutting manually
01:39 PM os1r1s: I think that is what I'll have to do
01:39 PM zeeshan: when the end mills break
01:39 PM zeeshan: do you see a glob of metal stuck in the flute?
01:39 PM os1r1s: Yeah. In the last one I did
01:39 PM zeeshan: use any oil
01:40 PM os1r1s: This is why I put mist on my other one. But I need to get these cut and don't have time to finish the enclosure
01:40 PM zeeshan: even vegie oil works
01:40 PM zeeshan: hehe
01:40 PM os1r1s: I have way oil or tapping fluid handy. But tempted to just get WD40
01:40 PM malcom2073: WD40 does amazing on aluminum in a pinch
01:40 PM Wolf_: I love my spray mister
01:40 PM Tom_L: vape for cnc
01:41 PM SpeedEvil: Tom_L: Well - you can put vape fluid in it.
01:41 PM SpeedEvil: :)
01:41 PM Wolf_: it would probably work as well lol
01:44 PM Wolf_: mist doesn’t need a giant enclosure http://i.imgur.com/ng0Ygak.jpg
01:47 PM _methods: just wear a raincoat
01:47 PM _methods: and rubber boots
01:49 PM pfred1: I have an ancient bijur spray mist coolant unit but i never had the guts to fire it up
01:50 PM malcom2073: Wolf_: How you're not getting chips all over your legs, I'm not sure
01:50 PM malcom2073: but when I machine, chips go 2ft in every direction heh
01:50 PM malcom2073: 3-4ft
01:50 PM malcom2073: 2-4* arg
01:50 PM Wolf_: see the mag switch with the lexan on it
01:50 PM malcom2073: yeah, it would def. bounce off the back piece and fly forward still :P
01:51 PM Wolf_: small chips + the mist my machine makes alum mud
01:51 PM malcom2073: ohhh, yeah the chips do look small
01:52 PM Wolf_: the rougher makes dust due to the tooth profile
01:52 PM Wolf_: pfred1: mine is a half diy setup http://i.imgur.com/6h18AtY.jpg
01:54 PM pfred1: Wolf_ i have one like this http://thumbs.ebaystatic.com/images/g/j5kAAOSwzOxUYQpd/s-l225.jpg
01:54 PM pfred1: plus there's a nozzle on a magnetic base with a hose
01:55 PM pfred1: the thought of vaping coolant just never really appealed ot me though
02:01 PM Wolf_: yeah, my setup runs at 30psi, so its not atomizing the coolant
02:03 PM os1r1s: Mist needs a compressor
02:03 PM os1r1s: Which is another issue ...
02:04 PM Wolf_: not at my house, shop and the house are plumbed in to the air system
02:04 PM pfred1: os1r1s every shop should be plumbed for air
02:04 PM pfred1: I remember when I first got compressed air i wondered why air wasn't in huoses like electrical outlets
02:05 PM os1r1s: pfred1 Its an electrical challenge. My mill using the full circuit to the garage
02:05 PM os1r1s: uses
02:05 PM os1r1s: So a compressor would put me over the top
02:05 PM pfred1: I still need to redo my one 240V cirsuit here
02:05 PM pfred1: every time i want to weld i have to unplug my mill
02:05 PM pfred1: its a hassle
02:05 PM Wolf_: 200 feet of 3/8 dot air line, my house has a 5 gallon air tank in the basement, shop has a 60gal w/ refrigerated air dryer on it
02:06 PM pfred1: but i have two 240VAC circuits on my shop so one for tools and one for the AC
02:07 PM pfred1: heck I even have my CNC spindle running on that one 240VAC line
02:08 PM pfred1: they wanted $6 more for a 120/230 PSU
02:08 PM pfred1: so I told them to stuff it I'd run it at the higher voltage
02:09 PM pfred1: I ran a line out of my table saw for it
02:09 PM pfred1: halfway through setting that up I regretted it though
02:09 PM pfred1: but it's done now
02:10 PM Wolf_: I put all my stuff on twist lock 3ph plugs
02:10 PM pfred1: the table saw has a twist lock
02:10 PM pfred1: the other plugs are them gigantic plug in models
02:10 PM Wolf_: welders and plasma will run on single-3phase
02:11 PM pfred1: my one 240V line i pretty gypo I ran it when I first moved in and i just tapped off the stove breaker
02:12 PM pfred1: so I can't cook and machine at the same time
02:12 PM Wolf_: lol
02:12 PM pfred1: well the break box is way over stuffed there's no way I could put another breaker in
02:12 PM pfred1: I have never seen such a packed panel and I used to do electrical work so I've seen some stuff
02:13 PM Wolf_: my shop is on a 100 breaker, feeding a 150 panel
02:13 PM pfred1: I really need to do a whole service
02:13 PM pfred1: but I really don't want to
02:13 PM pfred1: this place needs a pane ltwice the size of what it has
02:13 PM Wolf_: same here, my shop needs a new service run to it, and the house needs a new meter box
02:14 PM pfred1: electric is all this place has
02:14 PM pfred1: there's no gas
02:14 PM Wolf_: same
02:14 PM pfred1: I got an electric well too
02:15 PM pfred1: I suppose the septic has a pump in it as well but the less I know about that the better
02:15 PM Wolf_: it might, depends on the septic setup
02:16 PM pfred1: I have a mound so it ain't dreaining up there
02:16 PM pfred1: unless the laws of fluid dynamics are different here?
03:19 PM JT-Shop: gotta love people that say my stuff don't work when they didn't even buy it from me lol spyder stuff
03:22 PM CaptHindsight: JT-Shop: yup, maybe it's a competitor
03:40 PM JT-Shop: no, just old farts like me that can't remember where they got stuff
04:34 PM roycroft: /j ##homebrew
04:34 PM roycroft: ack
04:34 PM pfred1: roycroft what are you brewing?
04:34 PM roycroft: nothing today
04:34 PM roycroft: i brewed a batch of bitter yesterday though
04:35 PM pfred1: I live down the road from one of the best breweries in the world
04:35 PM roycroft: there would be a lot of contendors for that title
04:35 PM pfred1: I'm 5 minutes south of here https://www.dogfish.com/
04:35 PM roycroft: to which one are you referring?
04:35 PM roycroft: oh
04:35 PM roycroft: dogfish is ok sometimes
04:35 PM roycroft: sam makes some good brews
04:36 PM roycroft: and some crap
04:36 PM pfred1: it is OK al lthe time here
04:36 PM roycroft: it's pretty dodgy
04:36 PM pfred1: oh yeah you have to know which ones are good
04:36 PM roycroft: i like his midas touch ale
04:36 PM pfred1: sam is a bit cracked
04:36 PM roycroft: i want to brew something like that some day
04:36 PM roycroft: i'm not going to go to egypt to get dates with wild yeast on them though
04:36 PM pfred1: he's living proof that is always pays to marry money
04:37 PM Loetmichel: pfred1: i know. my wife has 3 times my salary... VERY handy sometimes ;)
04:37 PM roycroft: we don't get too many of his beers here
04:37 PM roycroft: people rave about his 120 minute ipa
04:37 PM roycroft: it's ok
04:37 PM roycroft: for an ipa
04:37 PM pfred1: yeah I don't liek the 120
04:38 PM roycroft: i think pliny the elder is vastly superior
04:38 PM pfred1: the 90 is OK
04:38 PM roycroft: but that stuff is impossible to get these days
04:38 PM pfred1: their favorite beer of mine is the burton baton
04:38 PM pfred1: see here i can get dogfish any time
04:38 PM roycroft: i don't think that vinnie even bottles it any more
04:38 PM pfred1: I can go up the road and they'll jsut give it to me
04:38 PM roycroft: and whenever a batch of pliny is about to be tapped there is a queue blocks long at the brewery waiting to get some
04:39 PM roycroft: it usually sells out within a couple hours
04:39 PM roycroft: santa rosa is too far for me to drive for beer
04:39 PM pfred1: sam has the largest wooden vats in the US
04:39 PM roycroft: and i do not queue up for things anyway
04:39 PM pfred1: 20,000 gallons
04:39 PM roycroft: but i had pliny years ago a couple times, when it was still being bottled
04:40 PM roycroft: and while not a fan of ipas, i must say it was really excellent
04:40 PM roycroft: dogfish make another beer i like a lot - raison d'etre
04:40 PM pfred1: I like IPAs
04:41 PM roycroft: i got burned out on them about 30 years ago
04:41 PM roycroft: it's all one could get around here for craft brew at the time
04:41 PM pfred1: I could drink DFH 60s forever
04:42 PM roycroft: i wouldn't mind trying burton baton
04:42 PM roycroft: it looks interesting
04:42 PM pfred1: here's one of their wooden vats http://beerlovescompany.com/wp-content/uploads/2012/12/image37.jpg
04:42 PM roycroft: having huge casks is not necessarily a good thing, btw
04:43 PM roycroft: it takes a lot longer to age a beer in a huge cask vs. a smaller one
04:43 PM pfred1: roycroft it is if you like having a lot of beer
04:43 PM pfred1: the palo santos used to be great when the vat was new
04:43 PM roycroft: lots of smaller ones is just as good as one big one
04:43 PM roycroft: as far as quantity
04:44 PM pfred1: but now they don't taste good to me anymore
04:44 PM pfred1: still put me on my ass
04:44 PM roycroft: that's another drawback to huge casks
04:44 PM pfred1: but burtons they're just delicious
04:44 PM roycroft: if the cask gets infected badly it's quite an expense to replace
04:44 PM pfred1: they clean it out
04:45 PM pfred1: caustic soda
04:45 PM roycroft: caustic in a wooden cask?
04:45 PM pfred1: I think so
04:45 PM roycroft: i've never heard of anyone doing that
04:45 PM pfred1: maybe I'm wrong
04:45 PM roycroft: usually you just rinse it out really well, and burn sulphur in it if you want to suppress bugs
04:45 PM pfred1: heck half the tiem when you take the tour they say different things
04:45 PM roycroft: once the bugs get in the cask you can never get rid of them
04:46 PM pfred1: what kind of bugs?
04:46 PM roycroft: the best you can do is kill off most of them and stun the rest, so that they are slow to come back
04:46 PM roycroft: wild yeast/bacteria
04:46 PM roycroft: i.e. any microorganism you don't want
04:46 PM pfred1: well beer stops fermenting because the alcohol content becomes lethal
04:46 PM roycroft: sort of
04:47 PM pfred1: that's why beer is different strengths
04:47 PM roycroft: that's a contributing factor
04:47 PM pfred1: some strains last better than others do
04:47 PM roycroft: the types of sugars the yeast can consume is another
04:48 PM roycroft: one of the big differences between lager yeasts and ale yeasts, for example, is that lager yeasts can metababolize maltiotriose (a trisaccharaide), while ale yeasts cannot
04:48 PM roycroft: so you can run out of food before the alcohol level is too high
04:48 PM pfred1: I don't like lagars
04:48 PM pfred1: I like ales
04:48 PM roycroft: i mostly brew ales, because i'm better at brewing them
04:49 PM roycroft: but i enjoy well-made lagers as well
04:49 PM roycroft: and brew them occasionally
04:49 PM Deejay: gn8
04:49 PM pfred1: as i understand it the lager proces is more technically challenging
04:49 PM roycroft: it can be
04:49 PM roycroft: fermentation temperature control is much more critical than with an ale, generally speaking
04:49 PM pfred1: I leave all the brewing to the experts
04:49 PM roycroft: pilsners are technically very challenging
04:50 PM roycroft: because they are so clean that they readily expose the slightest flaw in the brewing process
04:50 PM roycroft: as i said earlier, i'm burned out on ipas and don't enjoy them much these days
04:50 PM roycroft: that said, when i teach brewing classes, i generally start folks out with an ipa
04:50 PM roycroft: because it's a very simple process
04:50 PM pfred1: simple is good
04:51 PM roycroft: and because between the malt body and all the hop bitterness/flavor, minor flaws are masked pretty well
04:51 PM roycroft: so the batch almost always turns out well
04:51 PM roycroft: i move folks to cleaner, more subtle beers as they gain more experience
04:51 PM pfred1: DFH isn't bitter
04:51 PM roycroft: their ipas are bitter
04:51 PM pfred1: nah
04:51 PM roycroft: but they have a lot of malt body as well
04:51 PM roycroft: yes, they are
04:52 PM pfred1: no, they're not
04:52 PM roycroft: but the key is to balance the maltiness and the bitterness
04:52 PM roycroft: they absolutely are
04:52 PM pfred1: the key os continual hopping
04:52 PM roycroft: you just don't notice it
04:52 PM roycroft: because it's well-balanced
04:52 PM pfred1: they say it is because of their patented continual hopping process
04:52 PM roycroft: if they did not have a lot of bitterness they would be so sickly sweet you would not be able to drink them
04:52 PM roycroft: that's utter bullshit
04:53 PM roycroft: sierra nevada were doing continous hopping back in the early '90s
04:53 PM pfred1: I hate sierra nevada it tastes like sucking on pine needles to me
04:53 PM roycroft: and russian river do a lot of continous hopping
04:53 PM roycroft: pliny the elder, while not continously hopped, has a very complex dry hop schedule
04:54 PM roycroft: making it essentially continuously hopped
04:54 PM roycroft: i like some of sierra nevada's ales
04:54 PM pfred1: I haven't had it in so long
04:54 PM roycroft: they do rely a lot on citrusy, piney northwest hops
04:54 PM roycroft: which i rarely use
04:54 PM pfred1: because 1 i live next door to DFH and 2 I didn't like it
04:54 PM roycroft: i live very close to some of the biggest hop farms in the country
04:54 PM roycroft: and i use local hops maybe once/year or so
04:55 PM roycroft: for them that like the hops that grow around here, that's great
04:55 PM pfred1: I'd have to be daft to drink Sierra Nevada here
04:55 PM roycroft: have your northwest-style piney overhopped ipas
04:55 PM roycroft: i prefer earthy english hops and floral/herbal noble hops from germany and slovenia
04:55 PM pfred1: sam tried to grow hops
04:56 PM roycroft: did he end up dumping them? :)
04:56 PM pfred1: beats me I know I don't hear about it anymore
04:56 PM roycroft: did you watch his tv show?
04:56 PM roycroft: the one that lasted less than a season
04:56 PM pfred1: they just had some growing by the side of their restaurant for a while
04:56 PM pfred1: no I never caught an episode
04:57 PM roycroft: every episode he either dumped a batch or threatened to dump a batch
04:57 PM pfred1: well they had some problems
04:57 PM pfred1: now they run around with blow torches
04:57 PM roycroft: every episode he brewed a beer that in the best of circumstances (according to him) would take months to do properly
04:57 PM roycroft: and he would have a deadline of 2 weeks
04:57 PM pfred1: befor they crack a valve they blowtorch it
04:57 PM roycroft: and would "pull it off" and it would always be perfect
04:58 PM roycroft: he should clean his brewery
04:58 PM roycroft: that's really hard to do once it gets infected though
04:58 PM pfred1: I'm sure he has
04:59 PM roycroft: if you're looking to start a brewery it's usually cheaper and easier to either build a new building or buy/lease a building that has never been a brewery than to move into a defunct brewery that had gotten infected
04:59 PM roycroft: even though the defunct one has all the equipment there and is "ready to go"
04:59 PM pfred1: yeah DFH used to be a cannery
05:02 PM SpeedEvil: roycroft: just turn up the heat to 80C for a week.
05:02 PM roycroft: that won't do it
05:03 PM roycroft: not even close
05:03 PM pfred1: UV light?
05:03 PM roycroft: it would kill most of the active bugs
05:03 PM roycroft: but it won't phase the spores
05:03 PM roycroft: as soon as you drop the temperature and add some food the spores will start growing
05:03 PM pfred1: UV is germicidal
05:05 PM Valen: neat bleach for a month, that'll kill most stuff ;->
05:05 PM roycroft: it is, but it's difficult to get enough intensity to disinfect a whole brewery and to make sure every nook and cranny gets flooded with the uv light
05:05 PM Valen: add some ozone to the mix for flavour
05:05 PM roycroft: bleach will depassify your ss brewware, and it will rust
05:05 PM Valen: so pickle it again after
05:05 PM roycroft: depassivate, i suppose, is the better term
05:06 PM roycroft: or not use bleach in a brewery
05:06 PM roycroft: nobody does
05:06 PM roycroft: that's why there is caustic
05:06 PM roycroft: and other cleaners
05:06 PM Valen: if you are worried about it being infected though
05:07 PM roycroft: there are ways to sanitize without using bleach
05:07 PM roycroft: when you use bleach the cobolt oxide (protective layer in ss) reacts with the bleach to form cobolt chloride
05:08 PM roycroft: and then you get iron molecules exposed to the surface
05:08 PM roycroft: and you know what happens next
05:09 PM Valen: you run a load of nitric acid through the thing to wipe out survivors and re-passivate it ;->
05:10 PM roycroft: sure, but you do that with caustic
05:10 PM roycroft: you just don't use bleach
05:10 PM roycroft: it's not done in breweries
05:10 PM roycroft: caustic doesn't react as strongly as bleach, but any strong alkaline cleaner will react with the cobolt to some degree
05:11 PM pfred1: I love the smell of cobalt in the morning
05:11 PM roycroft: citric acid will also repassivate
05:11 PM roycroft: and star-san, which is a sanitizer widely used in the food industry and by homebrewers, will also repassivate
05:11 PM Valen: I reckons bleaching and passivating would be cheaper than building a new brewery
05:11 PM roycroft: it contains organic acids
05:11 PM roycroft: bleach won't kill everything
05:12 PM pfred1: Valen burn it down for the insurance money
05:12 PM roycroft: if you could autoclave your entire brewery that would be effective
05:13 PM roycroft: just build a giant autoclave around the building and fill it with pressurized steam for a couple days
05:13 PM pfred1: just make moonshine nothing can live in 200 proof alcohol
05:13 PM roycroft: it's impossible to make 200 proof alcohol by distillation
05:13 PM roycroft: 190 proof is the best you can get
05:14 PM pfred1: yeah I've had 190
05:14 PM pfred1: that stuff can strip paint
05:14 PM pfred1: red horse grain
05:14 PM roycroft: to suck that last 5% of water out you have to add other chemicals to bond to the water, and then remove the newly-created compounds
05:14 PM roycroft: i don't remember the process
05:14 PM pfred1: I still remember the burn
05:15 PM roycroft: i use everclear to clean pcbs
05:15 PM roycroft: i would never drink that stuff
05:15 PM roycroft: but it's really good at cleaning solder rosin off a pcb
05:15 PM pfred1: when you're young you can do a lot of crazy things
05:16 PM pfred1: I use stuff with Dimethal keytones in it
05:18 PM pfred1: I'm running low though
05:27 PM XXCoder: Wolf_: you alive?
05:27 PM Wolf_: maybe
05:27 PM XXCoder: oh probably is close enough lol
05:28 PM XXCoder: https://www.youtube.com/watch?v=1JMSRF6Q9uw
05:30 PM XXCoder: what ya think
05:31 PM pfred1: XXCoder well I was listening to https://www.youtube.com/watch?v=a3Cwoz_JnyM but I paused it
05:31 PM XXCoder: a picture. wonderful lol
05:32 PM pfred1: there is a long pausei n the beginning
05:32 PM Wolf_: looks good, needs more cutter :P
05:32 PM XXCoder: nah same picture all way to end
05:32 PM XXCoder: wolf yeah was a dry run to test mechinics, it was second run lol
05:33 PM pfred1: XXCoder if you don't customize TB6560s you can never get performance out of them
05:33 PM pfred1: you need fitted current sense resistors in TB6560s
05:34 PM pfred1: just flipping DIP swithes to change the current setting isn't going to do it
05:35 PM pfred1: so yeah TB6600s are a big step up in adjustment
05:35 PM pfred1: how'd you set the current on yours?
05:36 PM XXCoder: I set all 3 to 2A current
05:36 PM XXCoder: and 1/8 steps
05:36 PM pfred1: yes but what method did you use?
05:36 PM pfred1: what process
05:36 PM XXCoder: oh simple, switch on tb6600s
05:36 PM pfred1: like how'd you do it?
05:37 PM pfred1: you didn't measure the current with a meter?
05:37 PM XXCoder: nah need to do that
05:38 PM pfred1: what I did wa I broke one of the coil connections and put a meter in there then I joged rally slowly until i got the higest current reading
05:38 PM pfred1: then adjusted the current there
05:39 PM pfred1: your machine looked like it was going pretty good to me though
05:39 PM XXCoder: yeah its already way better
05:39 PM pfred1: TB6600s are smoking drives for the money
05:39 PM pfred1: what input voltage do you run?
05:39 PM XXCoder: 24v
05:40 PM pfred1: supposedly the ICs can do what 45V?
05:40 PM pfred1: but on my boards they say 32V so that's what I run
05:41 PM pfred1: the way your machine looks like it is moving I don't see how much faster yo ucan hope to go with it
05:41 PM XXCoder: nice. yeah with tb6560 tests it could do 300 mm/s
05:41 PM pfred1: I hit 200 inches per minute on my machine but tore up a lead nut
05:41 PM XXCoder: smoothly too, but problem was it was very vibrative
05:41 PM XXCoder: *at lower speeds
05:42 PM pfred1: the TB6600 vibrates?
05:42 PM XXCoder: hardly at all
05:42 PM pfred1: over current can run jerky
05:42 PM pfred1: it's weird over current motors strain
05:42 PM XXCoder: I tried all way down to 25% current nope sill issues
05:42 PM pfred1: yeah the commercial TB6560 boards how they do current is horsecrap
05:42 PM XXCoder: thats when I said fuk it get rid of tb6560
05:43 PM pfred1: thre's 2 current sense resistors on the drive that set the drive current
05:43 PM pfred1: and there's a formula that you use to calculate what value resistor you need to run for what current
05:43 PM XXCoder: there is very little resourances with tb6600s at around 3 mm/s and 7 mm/s, similiar with tb6560 but MUCH lower vibration so whatever
05:43 PM pfred1: the DIP switches just change the logical current inside the drive IC
05:43 PM XXCoder: can barely feel it
05:44 PM pfred1: well still check your current
05:44 PM XXCoder: yeah
05:44 PM pfred1: because totally dialed in they tun the best
05:44 PM pfred1: run even
05:44 PM pfred1: just with the power OFF disconnect a motor lead and put an ameter in line with it
05:44 PM XXCoder: theres knob on spindle psu also on current not too sure how check that. I guess just connect to +v and com and check current?
05:45 PM pfred1: then set your jog speed really slow and tap jog
05:45 PM pfred1: when you get your highest reading that is the current you'r running at
05:45 PM XXCoder: I want that to be close to rated
05:45 PM pfred1: yeah you can go right up to whatever your motors call for
05:45 PM pfred1: 2 amps or whatever
05:45 PM XXCoder: yeah its 2a
05:46 PM pfred1: but just check without a meter there's no way of knowing
05:46 PM pfred1: for home CNC routers TB6600s are great
05:46 PM pfred1: I think they cost $8.35 now?
05:47 PM pfred1: I just wish motors were cheap
05:47 PM os1r1s: pfred1 I wish Teknic made nema17 clearpaths
05:48 PM XXCoder: heh guys in reprap was recommanding me smoothieboard and other usb boards. no thanks :P
05:48 PM XXCoder: its good for 3d printer but for milling heck no
05:49 PM XXCoder: its not even remotely rt
05:49 PM pfred1: os1r1s my steppers will run 2,000 RPM which i beyond what i can make mechanics that can handle
05:49 PM XXCoder: nema is pretty cheap now
05:49 PM XXCoder: its shipping that hurts as its quite heavy
05:49 PM os1r1s: pfred1 I really dig the clearpath series after putting them on this mill
05:49 PM pfred1: XXCoder the 3D printer crowd is clueless hwne it come to performance
05:49 PM os1r1s: I'm sure its overkill, but they are fast, smooth, and quiet
05:50 PM XXCoder: its fine for 3d printing. hell ramps works for that and its ancient
05:50 PM pfred1: yah ramps is a joke
05:50 PM XXCoder: but for cutting and milling, realtime is a must.
05:50 PM pfred1: pololu chip carriers?
05:50 PM pfred1: they'r not even real motor drives
05:51 PM os1r1s: XXCoder Its arguable whether you consider boards like the smoothstepper realtime or not.
05:51 PM pfred1: do ramps boards work if you run them higher than 12V?
05:51 PM XXCoder: good question pf lol
05:51 PM os1r1s: pfred1 Ramps works up to 24V if memory serves
05:51 PM XXCoder: os USB is not realtime no matter what.
05:52 PM os1r1s: I have a few Rambo boards (successor to ramps) working at 24V.
05:52 PM pfred1: I'm amazed because the control lines are not isolated
05:52 PM XXCoder: it dont have any INT to cpu
05:52 PM os1r1s: XXCoder To be fair, I'm not sure if mesa boards to either
05:52 PM XXCoder: parallel port does.
05:52 PM os1r1s: XXCoder Using a 6i25 or 5i25 moves away from the pport
05:53 PM pfred1: omething weird is going on with my machine
05:53 PM XXCoder: ah that I dont know
05:53 PM os1r1s: For example, I'm running a 6i25 connected to a 7i76
05:53 PM os1r1s: In linuxcnc
05:53 PM pfred1: I run a few job and home it and it isn't back where it started anymore
05:53 PM XXCoder: ow
05:53 PM pfred1: thoiugh the jobs it run seem OK
05:54 PM pfred1: it is just something I noticed
05:54 PM XXCoder: any relation to orginial home to supposely current home and part coord?
05:55 PM XXCoder: there may be error somewhere
05:55 PM pfred1: I honestly have no idea what is going on yet
05:56 PM pfred1: this picture is a little blurry but check out this plot i did yesterday the text at the top is almost legible http://i.imgur.com/7ipdRXZ.jpg
05:56 PM pfred1: it just didn't come out in the photo
05:56 PM XXCoder: the old pen cnc eh heh
05:57 PM pfred1: yeah elcheapo ballpoint pen FTW
05:57 PM pfred1: I tried nice pens they don't work as good
05:57 PM XXCoder: been a while but did that with my machine
05:57 PM pfred1: oh i plot a lot
05:58 PM pfred1: I pretty much always plot a job before i cut it just to get a feel for it
05:58 PM pfred1: I sim but it isn't the same
06:02 PM pfred1: I'm jealous my CNC is a way better artist than I ever was
06:03 PM XXCoder: plotting against who? ;)
06:03 PM XXCoder: meh cnc is great on following instructions
06:05 PM SpeedEvil: Meth cnc less so
06:05 PM XXCoder: lol
06:06 PM XXCoder: mr evil, what ya think
06:07 PM XXCoder: of video
06:07 PM pfred1: rapid looked really rapid
06:08 PM pfred1: XXCoder do your motors get hot?
06:08 PM XXCoder: nope
06:08 PM XXCoder: but then didnt go really long runs
06:08 PM XXCoder: linuxcnc engrave was longest it ran
06:08 PM pfred1: they may actually heat up more sitting
06:09 PM pfred1: teppers are kind of backwards that way
06:09 PM XXCoder: oh ya highest torque and current at rest. forgot
06:09 PM XXCoder: didnt get really warm
06:09 PM pfred1: one step is your highest current draw per phase
06:09 PM Wolf_: http://i.imgur.com/XRTwasV.jpg toasty
06:09 PM pfred1: well in microstep it is just one of the microstep that is at the top
06:09 PM XXCoder: I still want one. :( heat camera
06:11 PM Wolf_: http://i.imgur.com/eotv49V.jpg http://i.imgur.com/W0pB6U3.jpg mine get warm
06:12 PM XXCoder: isnt that past the curie temperate
06:12 PM Wolf_: that in F not C
06:12 PM XXCoder: ah yea
06:12 PM XXCoder: too used to C lately lol
06:13 PM pfred1: I think I'd put fans on my motors if they got that hot
06:14 PM pfred1: it isn't unheard of
06:15 PM pfred1: some people heat sink their motors too
06:15 PM pfred1: just get some old heat sinks and strap them on
06:16 PM Wolf_: I think I turned the current down on drivers after I took that pic
06:17 PM pfred1: well motors can get pretty hot
06:18 PM Wolf_: 0.6A on the x/y and 1A on the Z
06:18 PM pfred1: that's it?
06:19 PM Wolf_: when holding
06:19 PM pfred1: ah hold current reduction
06:19 PM Wolf_: moving it gets to almost 3A
06:19 PM pfred1: gecko drives?
06:20 PM SpeedEvil: XXCoder: thermal cameras are coming down lots,which is nice.
06:20 PM sync_: 51°C isn't bad
06:20 PM sync_: the enamel usually is rated to 140°C
06:20 PM Wolf_: I think flir came out with a cell phone with thermal in it
06:21 PM sync_: the mitsubishi servos I have have no problem with 80°C case temp
06:21 PM pfred1: sync_ what is the bearing grease rated to?
06:21 PM sync_: more
06:21 PM pfred1: sweet!
06:21 PM sync_: currently seek thermal is the best bang for the buck imho
06:23 PM sync_: usually the greases will take 120°C no problem
06:24 PM sync_: I blew out one of the dustshields on one of the mitsubishis by running it at 8100rpm for an hour tho
06:24 PM sync_: got soft and walked off the shaft
06:25 PM XXCoder: SpeedEvil: nice! looking
06:25 PM Wolf_: this is pretty cool, not cheap tho http://www.flir.com/suas/duo/ same size as gopro
06:25 PM XXCoder: wolf that was my future plan, wait till that phone gets outdated
06:25 PM XXCoder: then buy one for 20 bucks
06:28 PM XXCoder: cheapest 175 bucks
06:29 PM sync_: the seek compactpro is ok, 320x240 is a nice resolution
06:29 PM sync_: quite cheap as well, 500$ iirc
06:29 PM SpeedEvil: https://www.youtube.com/watch?v=ugQJUSyidRg
06:29 PM SpeedEvil: cheerson cx20 with flir one and raspberry pi thermal vision drone flight fpv
06:30 PM XXCoder: http://www.ebay.com/itm/FLIR-ONE-THERMAL-IMAGER-CAMERA-ATTACHMENT-IPHONE-5-5S-iOS-435-0001-01-00-/282368337058
06:30 PM Wolf_: flir has some new phone attachments coming out soon
06:33 PM XXCoder: nice, hope that will lower prices more
06:33 PM Wolf_: http://www.flir.com/flirone/products/?id=81769 160x120 $399 msrp
06:34 PM SpeedEvil: Be careful about resolution - you really want to look at the produced image - some are pretty crap, and some of the software seems to have limits in it to protect revenue
06:34 PM SpeedEvil: - for example, not allowing you to set max/min, but autoranging.
06:35 PM XXCoder: yeah I remember reading something about resolution limition removal hack
06:35 PM SpeedEvil: Which is really, really annoying if you're trying to survey something
06:35 PM Wolf_: flir has the MSX overlay
06:35 PM SpeedEvil: Not that.
06:35 PM Wolf_: which is great at low rez
06:35 PM SpeedEvil: I mean features intentionally left out
06:35 PM XXCoder: http://fubar.gr/hacking-the-flir-e4/
06:36 PM Wolf_: yeah, I don’t remember what my e4 was missing stock
06:39 PM XXCoder: hack apparently adds change sensor to RNDIS mode, increase resolution to 320x240, and add PIP measure options, color palettes, etc
07:03 PM R2E4_bevins: WTF? +- 12v analog control for yaskawa drives?
07:03 PM chopper79: What drives?
07:04 PM R2E4_bevins: SGDB servopacks
07:04 PM JT-Shop: say goodnight Gracie
07:04 PM R2E4_bevins: goodnight Gracie
07:05 PM R2E4_bevins: mesa cards +-10V, that means would lose 12% of top speed?
07:06 PM R2E4_bevins: http://www.ghautomation.com/51down/SGDBUserManual%28sigma-1%20090001%20%E8%8B%B1%E6%96%87%29.pdf
07:06 PM R2E4_bevins: gnd in for inputs..... Cant win for losing
07:11 PM sync_: can't you use the pulsetrain input?
07:12 PM R2E4_bevins: Mesa has a card capable of pulse train?
07:13 PM R2E4_bevins: whatever a pulsetrain is
07:13 PM sync_: it's just 5V pulses
07:15 PM R2E4_bevins: I think thats more for control via PLC
07:16 PM R2E4_bevins: or PCU position control unit
07:17 PM R2E4_bevins: PAO /PAO PBO /PBO PCO /PCO encoder, check but +-12V?
07:17 PM zeeshan: R2E4_bevins: can you not scale your drives
07:17 PM zeeshan: so that 10v hits your target
07:17 PM zeeshan: that way you're only really losing resolution by not providing 12v
07:18 PM XXCoder: hey zeeshan you seen my video?
07:18 PM zeeshan: XXCoder: no
07:18 PM R2E4_bevins: yes but you loose speed
07:18 PM R2E4_bevins: or no... lol
07:18 PM XXCoder: https://www.youtube.com/watch?v=1JMSRF6Q9uw
07:18 PM zeeshan: R2E4_bevins: no
07:18 PM XXCoder: loose speed not good. tight speed is better!
07:19 PM zeeshan: XXCoder: send me that machine
07:19 PM zeeshan: i need an engraver!!!
07:19 PM XXCoder: sure $1,000 plus shipping
07:19 PM zeeshan: =[
07:20 PM XXCoder: heh honestly its a mess I need to pack electrics into nice box
07:20 PM XXCoder: ich never returned for while so I havent had chance to ask name of it.
07:20 PM XXCoder: ya know, box that can add walls to control wiring and mounts
07:20 PM XXCoder: so what ya think of machine sounds?
07:20 PM R2E4_bevins: ok so you would lose 12% of resolution?
07:21 PM R2E4_bevins: I dont find that very attractive
07:22 PM zeeshan: XXCoder: http://i.imgur.com/REXbWbd.jpg
07:22 PM zeeshan: check out the knots ive been working on
07:22 PM zeeshan: for my bushcraft stuff
07:22 PM zeeshan: :D
07:23 PM XXCoder: minecraft ;)
07:23 PM XXCoder: decent
07:23 PM zeeshan: who knows one day that paracord might be needed
07:23 PM zeeshan: :D
07:27 PM sync_: R2E4_bevins: it should work the same
07:28 PM R2E4_bevins: pulsetrain or the +-12v?
07:28 PM XXCoder: so what ya think of machine noises?
07:28 PM sync_: pulsetrain
07:28 PM XXCoder: I guess its way better from others comments so far.
07:32 PM R2E4_bevins: I'll print the manual and read it tomorrow.
07:39 PM R2E4_bevins: torque ref +-10v speed ref +-12v
07:50 PM os1r1s: Any reason not to use a drill bit in an R8 collet if the bit has a shank with the same size as the collet?
07:50 PM Tom_L: no
07:51 PM Tom_L: unless it's broken
07:51 PM os1r1s: Tom_L Awesome
07:51 PM os1r1s: Tom_L Thank you
07:58 PM R2E4_bevins: scored today....
07:58 PM R2E4_bevins: https://forum.linuxcnc.org/38-general-linuxcnc-questions/32002-biesse-rover-346-retrofit?start=210#88650
07:59 PM R2E4_bevins: except it is a 15hp 220 3phase motor. need a 60 amp transformer
08:00 PM Tom_L: bottom one a phase inverter?
08:00 PM R2E4_bevins: no, a vacuum pump
08:00 PM Tom_L: sorta looks like one
08:01 PM R2E4_bevins: rotary vane vacuum pump
08:02 PM Tom_L: screw compressor
08:03 PM R2E4_bevins: I need one of those.... I have a big 45hp two motor compressor but screw compressor is what I need. Plus it helps on heat in winter...lol
08:03 PM Tom_L: my bud had one, it was huge
08:04 PM Tom_L: in a room by itself
08:04 PM Tom_L: they're kinda noisy
08:11 PM R2E4_bevins: how do you calculate transformer needed 600=>220 for a 15hp electric motor
08:13 PM R2E4_bevins: 12 KVA should do it
08:35 PM cncnoob: Howdy. I just got my home/limit switches installed on my 3 axis mini mill and I'm having some trouble with the configuration
08:36 PM cncnoob: I have a C10 break out board so I have 5 inputs to work with
08:37 PM cncnoob: I used 3 of them as "Minimum Limit + {INSERT AXIS} Home"
08:37 PM pfred1: you could wire all your limit switches in series couldn't you?
08:37 PM cncnoob: Then wired the remaining 3 limit switches (the max positions) in series and ran them to a single pin
08:38 PM cncnoob: It didn't seem to make sense to wire them in series since I also want homing
08:38 PM pfred1: the machine always knows what direction it is going in, doesn't it?
08:38 PM XXCoder: well wonder if can wire Z to both X and Y, so if only X, it is X, if only Y it is Y, if both triggers at same time, it is Z?
08:39 PM XXCoder: would need 2 pins for that.
08:39 PM cncnoob: Here is what I was going off of
08:39 PM cncnoob: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Homing_And_Limit_Switch#Home_Min_Limit_Switch_for_Each_Axis_and_Combined_Max_Limit_Switches_for_all_Axis
08:39 PM XXCoder: while max ends can be serial, its only used for "oh shit too far"
08:39 PM cncnoob: Originally I had it wired differently, like this
08:39 PM cncnoob: http://cnc4pc.com/Tech_Docs/3_C10R10.pdf
08:40 PM pfred1: that's why I never put switches on my machine plus sometimes i like to lie to it
08:40 PM cncnoob: But that wasn't getting the desired results
08:40 PM XXCoder: honestly I would nto bother with max, just use software maxes
08:40 PM pfred1: I use soft limits
08:40 PM cncnoob: That works so long as your software doesn't mis-step
08:41 PM cncnoob: Well as of right now I'm not even dealing with the max limits
08:41 PM pfred1: computers don't make mistakes
08:41 PM cncnoob: I have them disabled in config. I'm just trying to get the home/mins to work
08:42 PM cncnoob: I think some of my troubles are related to my initial stepper config which I still scratch my head over
08:44 PM roycroft: computers do, indeed, make mistakes
08:45 PM cncnoob: I keep getting home switch activated before start of latch move
08:47 PM cncnoob: This is my Z axis config:
08:48 PM cncnoob: [AXIS_2]
08:48 PM cncnoob: TYPE = LINEAR
08:48 PM cncnoob: HOME = -0.001
08:48 PM cncnoob: MAX_VELOCITY = 1.0
08:48 PM cncnoob: MAX_ACCELERATION = 30.0
08:48 PM cncnoob: STEPGEN_MAXACCEL = 37.5
08:48 PM cncnoob: SCALE = 2000.0
08:48 PM cncnoob: FERROR = 0.05
08:48 PM cncnoob: MIN_FERROR = 0.01
08:48 PM cncnoob: MIN_LIMIT = -9.875
08:48 PM cncnoob: MAX_LIMIT = 0.0009
08:48 PM cncnoob: HOME_OFFSET = 0.000000
08:48 PM XXCoder: whoa
08:48 PM XXCoder: if more than 3 lines use dpaste or pastebin or whateer
08:48 PM cncnoob: will do
08:49 PM cncnoob: If you see the MIN_LIMIT it just doesn't seem correct
08:50 PM cncnoob: But that is what I had to set it at to 1.) get the tool to move in the correct direction with the button press AND 2.) have my home position at (or near) 0
08:51 PM cncnoob: When the Z axis is all the way up do you expect that to be the zero point for that axis?
08:51 PM XXCoder: http://assets.amuniversal.com/d63c40d0dc7201345867005056a9545d heh
08:53 PM cncnoob: At this junction in my day that is what I consider a non sequitur :)
08:53 PM XXCoder: it is.
08:58 PM XXCoder: cncnoob: that depends, some machines has lowest at zero, some highest
08:58 PM XXCoder: when its highest set as zero, you go negative to go down
08:58 PM XXCoder: my cnc router is set to -200 to 0 though need to set correct sizes later. (mm)
09:04 PM cncnoob: Ok, then my config doesn't look so crazy I guess
09:05 PM XXCoder: heh at work theres one machine that has zero at lowest
09:05 PM XXCoder: such annoyance.
09:06 PM pfred1: my machine X and Y home in the middle
09:07 PM pfred1: Z does too come to think about it
09:07 PM XXCoder: fancy. how do you repeat home position as needed?
09:07 PM pfred1: thre's an X on the table and I glued a spray straw to the Z axis as a pointer
09:07 PM pfred1: the spray straw is pretty accurate
09:08 PM cncnoob: The thing for me is that CAMWorks by default sets up GCode to send the machine home before it starts cutting
09:08 PM XXCoder: most cases thats fine
09:08 PM cncnoob: so driving the Z axis down is no good
09:08 PM cncnoob: http://pastebin.com/5WnYRzmm
09:08 PM XXCoder: but if you hit e-stop wouldnt it mean you would have hard time getting home correct position again to resume?
09:09 PM pfred1: XXCoder I can just restart a program
09:09 PM XXCoder: with new stock I guess
09:09 PM pfred1: nope
09:09 PM pfred1: just run over it all again
09:09 PM cncnoob: So my Y axis config is just as weird.
09:09 PM cncnoob: MIN_LIMIT = -3.875
09:09 PM cncnoob: MAX_LIMIT = 0.0009
09:10 PM pfred1: sometimes i run plots twice to darken lines
09:10 PM pfred1: machines goes right over the lines
09:11 PM cncnoob: Any ideas why I have to have a negative MIN_LIMIT on my Y? I want the zero point to be with the tool as far to the left as it can go.
09:12 PM pfred1: this is the first plot I ever did and the machine traced every line 3 times http://i.imgur.com/YjsaF5g.jpg
09:12 PM cncnoob: That was the only way I could make it do that AND have the keyboard short cuts work in the correct direction
09:12 PM XXCoder: pf whats you use to make gcode?
09:17 PM MacGalempsy: evening folks
09:18 PM XXCoder: hey
09:18 PM MacGalempsy: new spindle 100g go?
09:18 PM MacGalempsy: 100%
09:20 PM pfred1: XXCoder it depends on what I am doing
09:20 PM pfred1: if the scale doesn't matter then I like F-Engrave
09:20 PM XXCoder: the plotter thing?
09:20 PM XXCoder: ah that I downloaded but not have tried yet
09:20 PM pfred1: but if the scale matters i use DXF2gcode
09:20 PM XXCoder: mac yeah works great
09:21 PM pfred1: they're both pretty good
09:21 PM pfred1: for 2.5D anyways
09:21 PM XXCoder: yea ok
09:21 PM XXCoder: theres svg to gcode also if I recall
09:21 PM XXCoder: I like inkscape a lot.
09:21 PM pfred1: for 3S I've been messing with pycam
09:22 PM pfred1: 3D
09:22 PM pfred1: I think gcoderools in inkscape is worthless
09:22 PM XXCoder: I just wish freecad constrant draft could export to dxf
09:22 PM pfred1: gcodetools even
09:23 PM pfred1: I export DXF from inkscale and process it with Qcad then convert it in either F-Engrave or DXF2gcode
09:23 PM pfred1: XXCoder check this out http://i.imgur.com/MwbyoY2.png
09:24 PM pfred1: that's my experimental 3D tool chain
09:24 PM XXCoder: camotics
09:24 PM pfred1: that's a sim program
09:24 PM XXCoder: that one is weirdly buggy
09:24 PM XXCoder: I know
09:24 PM XXCoder: former name free SCAM heh
09:24 PM pfred1: it beats having to get up and go over to my machine controller to look at files
09:25 PM pfred1: but yeah it is a bit strange
09:25 PM pfred1: I like how when it sims when it is done it eraces the job
09:25 PM pfred1: who thought that was a good idea?
09:25 PM XXCoder: it always starts backwards
09:26 PM XXCoder: working from complete and going back
09:26 PM XXCoder: and its speed up/ slow down? there is NO 100% so I never know what speed its going at.,
09:26 PM pfred1: but at least when I open a file it shows me what it looks like
09:27 PM pfred1: not all free software is worth quite what it costs
09:27 PM XXCoder: heh yeah, theres that shitty cam
09:27 PM XXCoder: halcom or something?
09:27 PM pfred1: I haven't tried it yet
09:28 PM pfred1: you ever tried the built in image2gcode plugin in LinuxCNC?
09:28 PM XXCoder: yeah
09:28 PM pfred1: it works
09:29 PM XXCoder: one of my earlier videos pengin logo
09:29 PM XXCoder: my machine wasnt running well so it failed
09:29 PM pfred1: I made this with it http://i.imgur.com/vI1dfW9.jpg
09:29 PM pfred1: that's an image2gcode
09:30 PM XXCoder: yeah
09:30 PM pfred1: hell I couldn't do that with a router
09:30 PM XXCoder: why?
09:30 PM pfred1: I lack the focus I guess
09:31 PM pfred1: you can see my Z axis straw in this picture http://i.imgur.com/KXrsIpm.jpg
09:32 PM XXCoder: I think I see it.
09:32 PM XXCoder: to left of spindle
09:33 PM pfred1: yup that's it
09:33 PM XXCoder: have you considered camera?
09:33 PM XXCoder: its surpising workable and accurate
09:33 PM pfred1: it is one of them spray can straws
09:33 PM pfred1: like you get on WD-40
09:33 PM XXCoder: if add the cross and align it on cross on background
09:34 PM pfred1: the cross on my table is a bit hard to see in the picture
09:35 PM pfred1: I'm getting ready to isolation route anotehr PCB
09:35 PM XXCoder: cool :)
09:37 PM pfred1: here's the layout http://i.imgur.com/HiDzOdY.png
09:38 PM pfred1: I'll trace that in inkscape then process it in DXF2gcode
09:38 PM XXCoder: 5k cap eh
09:38 PM pfred1: that's the pot over the cap
09:38 PM pfred1: I don't do the silkscreen so I don't even try to tweak it
09:38 PM XXCoder: im not expert on electric heh
09:38 PM pfred1: me either
09:39 PM pfred1: ut I do like to blow stuff up
09:39 PM pfred1: when i buy parts i buy lots of extras
09:39 PM pfred1: the last I I bought I got 20 of the little buggers
09:39 PM pfred1: IC
09:40 PM pfred1: because i know I'm going to cook a pile of those figuring out how it works
09:40 PM XXCoder: I still wonder if capactor powered flashlight will ever happen
09:40 PM pfred1: I think they make them
09:40 PM enleth: https://hackerspace.pl/~enleth/2017-02-26-upgrade/IMG_0040.JPG - new laser tube came in yesterday
09:41 PM XXCoder: huge laser. getting huge shark?
09:41 PM XXCoder: pf the jackoff flashlights dont count heh
09:41 PM enleth: 30cm longer and 5mm thicker than the factory tube, it was a tight fit in the LY3040 chassis
09:41 PM pfred1: running lasers gets to be expensive
09:41 PM pfred1: the bulbs don't last forever, do they?
09:42 PM XXCoder: nope if I receall from my research
09:42 PM XXCoder: 5k hours?
09:42 PM enleth: pfred1: for chinese lasers, you treat them as consumables, not parts
09:42 PM XXCoder: then it starts to taper off to too weak
09:42 PM pfred1: yeah I looked int oit you have to figure how much it costs a monute to run a laser
09:43 PM pfred1: some cost more than others do
09:43 PM pfred1: thjen there's screwing up the optics that can happen pretty much instantly
09:43 PM enleth: chinese optics are consumables as well
09:44 PM pfred1: burn the wrong stuff without exhaust and all optics get wasted
09:44 PM pfred1: I've heard a lot of horror stories about cheap plywood
09:44 PM enleth: uh, doing anything without exhaust on a laser cutter is asking for trouble
09:45 PM pfred1: people learn real fast to use the birch
09:45 PM enleth: and it's not a matter of "cheap" plywood, but rather of the type of glue used in the plywood
09:45 PM enleth: water-resistant glue is completely laser-proof
09:45 PM enleth: water-based glues are OK
09:45 PM pfred1: everyone makes the plywood mistake
09:46 PM enleth: very old plywood scavenged from furniture usually cuts well
09:46 PM enleth: and most plywood suppliers actually specify if their products can be laser-cut
09:47 PM enleth: https://hackerspace.pl/~enleth/2017-02-26-upgrade/IMG_0053.JPG - the original chassis did have a short extension for the far end of the tube, but we had to extend the extension a tiny bit here
09:47 PM pfred1: so how many Watts is this laser?
09:47 PM enleth: 60W rated power and it looks like it might actually be able to provide that
09:47 PM XXCoder: 60w chinese watts
09:47 PM pfred1: yeah 60W is n joke
09:48 PM pfred1: use protective gear with one remaining good eye
09:48 PM enleth: I have to test it, but it's quite a bit longer and thicker than many "60W" tubes I've seen so far
09:48 PM enleth: and the build quality is much higher
09:48 PM enleth: so, we'll see
09:49 PM pfred1: I can remember when I was in grammer school the geeks from Bell Labs came to my school to give us a presentation about lasers
09:49 PM pfred1: you never seen a bunch of grown men so excited
09:49 PM pfred1: outside of a strip club at least
09:49 PM enleth: besides, for most things you don't ever use the full power
09:50 PM pfred1: back then no one evne had a laser that could pop a balloon
09:50 PM pfred1: so they faked it
09:50 PM pfred1: this was in the early 1970s
09:52 PM pfred1: lasers were the things of comic books back then
09:52 PM XXCoder: heh theres weird stuff there too
09:52 PM XXCoder: like vibroium heh
09:52 PM XXCoder: solid sound :P
09:53 PM pfred1: vivoleum?
09:53 PM XXCoder: no
09:53 PM pfred1: that's fuel made out of people
09:53 PM pfred1: a Yes Men gag
09:53 PM XXCoder: oh
09:54 PM pfred1: they gav a talk at Exxon about it
09:54 PM pfred1: they got a round of applause from th crowd too
09:54 PM pfred1: before evryone figured out they were being had
09:55 PM XXCoder: soylent green is better use for people I think. heh
09:55 PM XXCoder: in book it isnt people
09:55 PM pfred1: http://vivoleum.com.yeslab.org/
09:55 PM pfred1: hey soylent green is coming true
09:56 PM pfred1: we are fishing out the world's oceans
09:56 PM pfred1: which 30 years ago I would not have thought was possible
09:56 PM XXCoder: yeah
09:56 PM XXCoder: I drink soylent btw heh
09:58 PM pfred1: there are more than twice as many people on Earth today as the day I was born
09:58 PM os1r1s: Anyone think .125 DOC and .125 stepover with an 3/8 alum roughing end mill at 2250 rpm and 6ipm is a bad idea?
09:58 PM pfred1: how many HP spindle?
09:58 PM XXCoder: pf good news is rate of rate of growth is negative for first time
09:59 PM os1r1s: 1 HP G0704 size machine
09:59 PM pfred1: yeah it should work
09:59 PM XXCoder: so doubling rate is slower now than couple years ago
09:59 PM pfred1: XXCoder the agencies responsible for publishing the numbers are lying
09:59 PM os1r1s: pfred1 6061 no coolant
10:00 PM XXCoder: evidence?
10:00 PM pfred1: what size tool?
10:00 PM os1r1s: pfred1 3/8
10:00 PM pfred1: hmm 220 SFPM
10:01 PM pfred1: what is the tool made of?
10:01 PM os1r1s: Its a niagra alum roughing end mill (3 flute) ticn coated
10:01 PM pfred1: carbide?
10:01 PM os1r1s: Yah
10:02 PM pfred1: yeah you could go faster is that the machine's top speed?
10:02 PM os1r1s: Top RPM but not top feed
10:02 PM pfred1: yes RPM
10:02 PM pfred1: that's what's limiting you
10:02 PM os1r1s: I was hoping to get to deeper cuts with the same stepover
10:02 PM pfred1: carbide in aluminum the sky's the limit pretty much
10:03 PM pfred1: you could run 3X the RPMs
10:03 PM os1r1s: I run 10k on my shertaig, but I need to up the pulley on this one to do something faster
10:03 PM pfred1: what people do is shallow depth of cut and rapid feed
10:04 PM pfred1: and adaptive paths too
10:04 PM os1r1s: pfred1 I do use adaptive paths when I clearing pockets
10:04 PM pfred1: yup
10:05 PM os1r1s: So when you say shallow DOC, wouldn't you consider .125 fairly shallow?
10:05 PM pfred1: I suppose
10:05 PM pfred1: why 6 IPM?
10:06 PM pfred1: is that the right ship load?
10:06 PM pfred1: chip load even
10:06 PM XXCoder: .125mm?
10:07 PM pfred1: lordy this chart doesn't even start to 125 IPM
10:08 PM pfred1: Chip Load = feed rate ( ipm ) ÷ ( cutting rpm x number of cutting edges )
10:08 PM os1r1s: pfred1 Plugged it into Gwizard and that was the recommendation
10:09 PM pfred1: seems kinda slow
10:09 PM pfred1: kinda really slow
10:10 PM os1r1s: It feels really slow
10:10 PM os1r1s: :)
10:10 PM pfred1: how many teeth 4?
10:10 PM os1r1s: 3
10:10 PM pfred1: your chip load is 0.00088
10:11 PM pfred1: it should be like 0.004 I think?
10:11 PM pfred1: so 60 IPM would be more like it
10:11 PM os1r1s: Its N76231 from http://www.niagaracutter.com/carbide-high-performance/elite-series-for-aluminum-and-non-ferrous/ar330-3-flute-coarse-pitch-rougher
10:11 PM pfred1: well no 30?
10:12 PM pfred1: I wondered what feeds i should run so I just did a test
10:12 PM pfred1: I setup a job that just cut faster, and deeper
10:13 PM pfred1: I stiopped when i was going much faster and deeper than I thought was rational
10:13 PM pfred1: but it still worked
10:14 PM os1r1s: The website says the inch/tooth should be around .003
10:14 PM pfred1: this is the formula Chip Load = feed rate ( ipm ) ÷ ( cutting rpm x number of cutting edges )
10:14 PM pfred1: oh wait did I divide the teeth>
10:14 PM XXCoder: if I recall theres a table for optitial chiploads?
10:15 PM pfred1: it still comes out to 0.008
10:16 PM pfred1: it's because your RPMs are too low
10:16 PM pfred1: people machine aluminum at like 18,000 RPM
10:16 PM os1r1s: So you think 6 IPM is sae
10:16 PM os1r1s: safe
10:17 PM pfred1: what's the worst that can happen you snap an end mill?
10:18 PM pfred1: why no cutting fluid?
10:18 PM pfred1: people love WD-40 on aluminum
10:20 PM XXCoder: wd40 is pretty effective,
10:20 PM pfred1: you gotz to slick it up some
10:20 PM XXCoder: giant router at old job I used wd40 all time
10:20 PM pfred1: it gives that nice surface finish
10:21 PM pfred1: I buy WD by the gallon jug it is pretty economical that way
10:21 PM XXCoder: yeah no need to have pressured cans
10:22 PM pfred1: yeah I have a spray pump
10:22 PM pfred1: cans go too fast and cost too much
10:23 PM pfred1: the humidity is so high here everything rusts while I'm looking at it
10:23 PM pfred1: so I go through WD
10:24 PM pfred1: it's WD or wire wheels take my pick
11:10 PM CaptHindsight: hhmm had to disable KMS in the RTAI kernel in 2.7.8 to keep the latency jitter low
11:27 PM XXCoder: hnm
11:27 PM XXCoder: https://www.youtube.com/watch?v=NZJCxMN9NWk
11:27 PM XXCoder: caps in controller connections?
11:27 PM XXCoder: I guess it helps it avoid "brownouts"
11:31 PM Wolf_: yeah, they are on the power in lines
11:32 PM XXCoder: damn
11:32 PM XXCoder: pluge was way too fast on first metal test
11:32 PM XXCoder: second one better
11:33 PM XXCoder: back
11:33 PM XXCoder: er be back later
11:33 PM os1r1s: Woohoo, it worked ... https://www.dropbox.com/s/8csb6ocd55jox6z/eustaluxend.jpg?dl=0
11:33 PM XXCoder: first metal cut?
11:33 PM os1r1s: XXCoder On this mill
11:34 PM XXCoder: nice
11:34 PM os1r1s: I got a PM25 and CNCed it
11:34 PM os1r1s: Its been a long time in the making ....
11:34 PM XXCoder: same as my cnc router lol laters
