[01:34:03] <hatch789> hey guys is there a way to adjust a small signal (tiny voltage) out of the signal with the .ini file perhaps? like mine is showing .01v and making my axis move a tiny bit when I have the power off to linuxCNC
[01:34:31] <hatch789> there is a DEADBAND setting in the .ini file is this what I can change to try to get 0.00v on the multimeter?

[01:41:49] <roycroft> well my vfd and motor combo works brilliantly, except it takes about 30 seconds to ramp up to speed
[01:42:00] <roycroft> i'll have to see if i can tweak that
[01:42:14] <roycroft> i can stall the motor by hand at about 8Hz
[01:42:30] <roycroft> and i don't anticipate i'll ever need to run it that slow, so that's great
[01:43:12] <roycroft> i estimate that to be ~460rpm
[01:43:18] -!- chupacabra has quit [Ping timeout: 250 seconds]
[01:43:34] <roycroft> assuming the speed/frequency curve is linear
[01:46:30] <gregcnc> hatch789 servos should not have power when linucnc is not running/machine is off/estop is in
[01:46:38] -!- micges has quit [Quit: Wychodzi]
[01:46:56] <gregcnc> there is a bias setting, but your amp should also have bias
[01:49:17] <skunkworks> Estop out - power supply to drive gets activated.. Linuxcnc on - drives get enabled.

[01:52:35] <hatch789> I have not performed setup to that degree yet
[01:53:18] <hatch789> so when I press power to my servos on my MILL and then don't have power on in linuxcnc. THere is a small voltage on the signal wire that makes the axis move just ever so slightly

[01:53:40] <hatch789> I know I can take this out at the amp but I was wondering if there is a way to take it out in linuxcnc also
[01:55:52] <skunkworks> if that is happening then the hardware setup/config isn't correct.

[14:07:07] <SpeedEvil> Quicker.
[14:09:35] <enleth> SpeedEvil: you don't even need that for some padlocks. A friend of mine was trying to open a padlock to get to some stuff that belonged to us but was locked up by the landlord by mistake and we needed it *fast*. He started poking the padlock with a lockpick - no torque wrench at this point - just to get a feel of how many pins are there. He was talking with me in the process, looking at me, not the
[14:09:41] <enleth> padlock, and suddently the thing dropped from his hands to the floor.
[14:10:18] <enleth> Let me reiterate: it sprung open because someone was trying to determine how many pins are there, not actually trying to open it yet.
[14:10:23] <SpeedEvil> yeah - I knwo - I was just amused by the above

[15:53:44] <roycroft> i'm considering a braking resistor for my grinder motor, and want to be sure i understand what i can get
[15:54:13] <roycroft> if the power rating of the resistor is the same as the vfd specifies, but the resistance is slightly higher, that should work fine, but will brake a bit more slowly, right?
[15:54:20] <SpeedEvil> yes
[15:54:39] <SpeedEvil> heating elements are a good cheap source
[15:55:09] <roycroft> for example, the vfd specifies 70 ohms @300 watts, but it's a 2.2kw vfd
[15:55:22] <SpeedEvil> http://www.ebay.co.uk/itm/Bush-AE6BFS-Top-Oven-Grill-Heating-Element-Square-1200-1400w-/141799490488?hash=item2103e883b8:g:MDYAAOSw~bFWG4Zm
[15:55:23] <roycroft> my motor is 2hp, and the spec for the 1.5k2 vfd is 100 ohms $300w
[15:55:36] <Jymmm> find an old electric stove heating element coil =)
[15:55:40] <roycroft> i found a nice braking resistor that's 117 ohms @300w
[15:56:07] <roycroft> nice meaning brand new and made in the usa
[15:56:20] <SpeedEvil> you could always parallel with a 500 ohm 50W one
[15:56:29] <roycroft> sure
[15:56:43] <SpeedEvil> It's almost certainly not going to be noticable though
[15:57:17] <roycroft> the motor takes 30 seconds to spin down as it is set up right now
[15:57:25] <roycroft> i'd like to stop it faster
[15:57:26] <gregcnc> no dc braking?
[15:57:50] <roycroft> i need the braking resistor for that
[15:57:58] <gregcnc> not for DC
[15:59:18] <roycroft> oh, there is a dc braking feature
[15:59:22] <roycroft> i should look at that
[16:00:30] <roycroft> http://www.jinlantrade.com/ebay/invertermanual.pdf
[16:00:38] <roycroft> that's the manual for my inverter, in case anyone is interested
[16:00:40] <pcw_home> DC braking uses the rotor for the braking resistor :-)
[16:00:51] <roycroft> it's not engrish, but it's terse
[16:01:17] <roycroft> there's a parameter for dc braking
[16:01:24] <roycroft> it's set to 2% by default
[16:01:31] <roycroft> and can be set up to 20%
[16:01:42] <roycroft> so adjusting that up might help for now
[16:02:12] <gregcnc> you may need to enable DC braking
[16:02:23] <roycroft> yes, i'm looking for a toggle parameter
[16:03:27] <roycroft> and there is a parameter for that
[16:03:31] <roycroft> two, actually
[16:03:51] <roycroft> one for dc braking at start - used to ensure the motor is not rotating the wrong direction at start
[16:03:55] <roycroft> and one for dc braking at stop
[16:04:00] <roycroft> which is disabled by default
[16:04:53] <roycroft> there's also a stopping mode parameter which can be set to decelerate or coast, and it's set to decelerate by default
[16:04:57] <roycroft> which explains the 30 second spin-down

[16:08:14] <roycroft> i found out last night that the serial number of my inverter is 65536
[16:08:23] <roycroft> i wonder how many of them share that same serial number
[16:08:31] <roycroft> i would guess all of them
[16:08:36] <enleth> roycroft: unless your spindle is pretty heavy, you should be able to cut the deceleration time down a lot safely even without a brake
[16:09:43] -!- zeeshan has quit [Ping timeout: 244 seconds]
[16:09:47] <enleth> roycroft: I'm stopping a 2hp Bridgeport spindle motor in 3s without a braking resistor and the measured bus voltages don't exceed the VFD's maximum back-EMF rating
[16:09:51] <roycroft> enleth: last night i changed only the parameters required to test basic functionality
[16:10:11] <roycroft> i haven't done anything with acceleration/deceleration times yet
[16:10:22] <gregcnc> Enleth DC or decel ramp?
[16:10:23] <roycroft> that will be my next round of testing
[16:10:29] <enleth> roycroft: I'd need a braking resistor though, if I wanted the e-stop to stop the thing dead nuts within a couple revolutions
[16:10:34] <enleth> gregcnc: ramp
[16:10:42] <roycroft> and i might want that, enleth
[16:10:55] <enleth> but for a tool change stop, within 3s is fine
[16:11:01] <roycroft> i've been using grinders for decades, and have never needed to stop one instantly before
[16:11:17] <roycroft> but there could be a situation where that's useful or critical
[16:11:27] <enleth> I tried a 2s ramp, but the voltage spikes have been a bit worrying, so I kept it at 3s
[16:11:50] <roycroft> i'll experiment with the ramp times, and dc braking, before deciding if i want a braking resistor
[16:11:51] <gregcnc> been using DC braking on my lathe for years now.
[16:12:50] <roycroft> when i was in machining classes i always found it impressive that i could flip the forward-reverse switch and the lathe would instantly change directions
[16:12:57] <roycroft> i don't need that
[16:13:06] <CaptHindsight> you could modify a disc brake from an auto to act a s a clutch and then absorb the energy into a paddle wheel mounted in a fish tank filled with water
[16:13:10] <roycroft> perhaps when tapping it would be useful
[16:13:17] <roycroft> but on a grinder i certainly don't need it
[16:14:11] <enleth> or even just install an automotive brake on the back of the spindle
[16:14:25] <roycroft> 3 seconds would be more then sufficient for a grinder, i should think
[16:14:33] <enleth> a brake designed to stop a 2ton car going at a high speed should handle a machine spindle nicely
[16:15:24] <roycroft> a big bollard will stop the car car faster than a brake
[16:15:50] <enleth> unless it turns out to brake too sharply for the grinding wheel mount to take it
[16:18:53] <CaptHindsight> use smaller brake pads
[16:20:06] <CaptHindsight> or a hydraulic coupled clutch, open the valve when the wheel should stop
[16:20:46] <CaptHindsight> a torque converter
[16:20:50] <roycroft> my motor does whine quite a bit while on the inverter, btw
[16:21:01] <roycroft> i shall solve that problem by turning up the volume on my shop stereo
[16:22:41] <CaptHindsight> how about ear plugs that close when the sound level goes above 70db?
[16:23:38] <roycroft> there are some fancy noise-cancelling headphones that would let me listen to music while blocking out noise without having to turn the music up to eardrum-piercing levels
[16:23:42] <CaptHindsight> I think 70db is the level that nagging also occurs
[16:23:46] <roycroft> but they're pretty expensive
[16:23:50] <roycroft> i should look into them though
[16:23:57] <roycroft> especially if there's a bluetooth version
[16:24:16] <CaptHindsight> they have dropped in price since they are so popular for air travel
[16:24:35] <CaptHindsight> I need a version that is tuned to cancel out baby crying
[16:24:37] <Polymorphism> active electronic shooters muffs
[16:24:38] <roycroft> i don't think they're 100% effective at blocking out noise, but that's good
[16:24:49] <roycroft> i want to hear my machines so i know if something is wrong
[16:24:54] <gregcnc> one of my motors doesn't behave well on the VFD. loses sync at times. don't have a megger to check the motor, but I suspect the 50$ ebay AB vfd
[16:24:55] <Polymorphism> thats what you need
[16:25:57] <Polymorphism> https://www.amazon.com/Howard-Leight-Amplification-Electronic-R-01526/dp/B001T7QJ9O/ something like this perhaps
[16:26:44] <roycroft> yeah, something like that could work
[16:26:58] <roycroft> and while bluetooth would be nice, i still use an ipod all the time, which is tiny
[16:27:07] <roycroft> it generally docks to my shop stereo
[16:27:13] <roycroft> but it can live in my pocket
[16:27:29] <roycroft> the color doesn't excite me
[16:27:45] <gregcnc> I put noise amplifiers on my machines like the Harley guys
[16:27:47] <djdelorie> spray paint it
[16:27:50] <roycroft> but that can be fixed :)
[16:28:07] * roycroft would tie-dye his
[16:28:30] <djdelorie> find any teenage girl and tell them to nail polish it

[19:54:37] <andypugh> It’s easy to get Paypal, I think.
[19:54:54] <JT-Shop> you don't need PayPal
[19:55:18] <JT-Shop> I use PayPal to handle credit card charges
[19:55:27] <Frank_11> i send it to your paypal account
[19:55:36] <JT-Shop> no don't do that
[19:55:40] <Frank_11> lol
[19:55:55] <Frank_11> debit card too?
[19:56:00] <JT-Shop> place an order online and at checkout you go to PayPal and give your CC info
[19:56:04] <JT-Shop> yea
[19:56:22] <Frank_11> ohh
[19:56:25] <JT-Shop> Orlando is prob 2-3 days from here
[19:56:50] <Frank_11> i hope the hotel doesnt charge me for holding the package

[20:18:16] <Frank_11> a family member,
[20:18:21] <Frank_11> until 4th of july
[20:18:34] <Frank_11> just noticed thats your independance day lol
[20:19:01] <XXCoder> yeah pollute the sky day
[20:19:16] <Frank_11> hehe
[20:21:26] <XXCoder> I wonder how much all those fireworks affect weather, but I bet you scientists dont want to be party pooper heh
[20:21:46] <djdelorie> the scientists will insist on extended experimentation...
[20:21:58] <XXCoder> lol
[20:22:06] <XXCoder> fireworks week! lol
[20:22:30] <andypugh> 50 years of observations by me indicate that it is always foggy the day after the 5th of November.
[20:22:49] <alex4nder> andypugh / archivist : yah,.. that speed controller has been used for a bunch of electric skateboard products.. and now it supposed quadrature encoders
[20:23:01] <alex4nder> and there's been work on supporting step / dir
[20:23:06] <djdelorie> yeah, but that's the UK - it's always foggy the day after *every* day...
[20:23:28] <andypugh> It wasn’t _very_ foggy today.
[20:23:31] <alex4nder> I just ordered 10 PCBs for $84 shipped.. and the BoM for each ESC is ~$80
[20:24:12] <djdelorie> saying "it might be foggy" in the UK is like saying "it might snow" in New Hampshire.
[20:24:34] <andypugh> alex4nder: If it’s open-source couldn’t you order your own PCBs for less?
[20:24:41] <XXCoder> it used to be "it might rain" in west washington, but it dont rain as much as it used to in summers now
[20:24:47] <XXCoder> but winter it rains more
[20:25:00] <XXCoder> (spring, winter and fall)
[20:25:00] <alex4nder> andypugh: the $84 PCBs was me ordering them .. it's a 4 layer board
[20:25:01] <djdelorie> yeah, we don't have nearly as much August snow as we used to...
[20:25:10] <andypugh> alex4nder: How big?
[20:26:27] <andypugh> For 4-layer $84 isn’t too bad. Possibly cheaper here, but not by a huge margin:
http://www.seeedstudio.com/fusion_pcb.html
[20:27:13] <andypugh> Seeed have basically stopped me even trying to make PCBs. I have found that I can pretty much do something else on a project for 10 days.
[20:28:19] <SpeedEvil> yeah
[20:28:30] <SpeedEvil> For hobby projects, it's rare there is that much of a deadline
[20:28:54] <SpeedEvil> plus - even if there is, you can spend much of that time compensating for crappy DIY PCB
[20:28:55] <alex4nder> andypugh: they're pretty small... I want to say ~1.5"x2.5"

[22:53:10] <Sync> pfft
[22:59:46] <JT-Shop> Tom_itx: at your house?
[22:59:56] <Sync> andypugh: that's what I hate about composite parts all the time, a lot of work goes into the patterns and then you find out that your part does not work :/
[23:01:14] <andypugh> A friend watched it and was full of “I will try that tonight” then realised that 18 minutes of video is probably a good week of sanding, filling, painting and polishing.
[23:03:51] <Sync> well, it is an afternoon, but yeah
[23:05:24] <andypugh> There are a few waits of “several hours” for things to cure.

[23:06:09] -!- kingarmadillo has quit [Ping timeout: 246 seconds]
[23:07:45] <Sync> that depends on your resin system, but yes
[23:08:08] <Sync> I'm usually opting for fast cure resins as there is nothing worse than watching resin cure
[23:10:03] <Sync> and possibly several hundered dollars in resins later, that's also one thing I hate about stuff like that
[23:10:08] <Sync> if you buy it in bulk it is cheap
[23:10:18] <Sync> but small quantities are overly expensive
[23:10:23] <andypugh> The final result at the end of the third video is pretty umpressive.
[23:10:39] <andypugh> (impressive)
[23:11:39] <Sync> yeah, using prepreg is seksi

[23:32:40] <JT-Shop> http://gnipsel.com/recipes/beef/korean-hamburgers.html
[23:35:14] <andypugh> Serious lack of kimchi
[23:36:49] <CaptHindsight> http://www.mos.co.jp/global/ Japanese hamburger chain
[23:38:10] <SpeedEvil> Prepeg is annoyingly more 'in bulk' problems than just about anything else.
[23:38:16] <SpeedEvil> Need to keep it in the freezer even.
[23:40:08] <CaptHindsight> UV cure prepreg requires no refrigeration
[23:41:23] <SpeedEvil> Not seen that. I keep meaning to investigate UV photoinitiators for conventional resins
[23:41:48] <CaptHindsight> won't work with most conventional resins
[23:42:18] <JT-Shop> working on the kimchi, a buddy sent me some of his mom's vegan kimchi and it was good
[23:43:07] <CaptHindsight> by conventional you are probably referring to OH bonds cured by DIMETHYLANILINE,N,N-, MEKP or benzoyl peroxide
[23:43:57] <CaptHindsight> UV uses free radical or cationic curing
[23:46:06] <Jymmm> FREE THE UV from radical tyranny!!!

[23:48:49] <SpeedEvil> For polyester/styrene resin
[23:49:07] <SpeedEvil> Though I should not try to comment on this when asleep.
[23:49:21] <CaptHindsight> TPO will work
[23:50:20] <SpeedEvil> I need to get my 'shop' built and waterproof before fuckign with that alas.

[23:52:03] <CaptHindsight> but styrene is pretty stinky
[23:52:07] <SpeedEvil> meh.
[23:52:16] <SpeedEvil> It is indeed.
[23:52:37] <SpeedEvil> Part of the shop is supplied breathing air and proper extraction.
[23:53:04] <SpeedEvil> Also - nice that it has activity plentiful up to 400nm - so blue LED works just fine
[23:53:41] <CaptHindsight> blu ray 405nm, not blue 260nm
[23:53:56] <CaptHindsight> sorry 460nm
[23:54:00] <SpeedEvil> yes
[23:54:13] <Tom_itx> JT-Shop, yes
[23:55:31] <SpeedEvil> oops
[23:55:38] <CaptHindsight> http://www.epoxyproducts.com/chemistry.html#part1 good overview
[23:55:51] <SpeedEvil> yes, for some reason I forgot that it was 450nm most LEDs start out at
[23:56:00] <SpeedEvil> - probably as I have a DVD laser
[23:56:04] <SpeedEvil> Thanks!
[23:58:48] <SpeedEvil> yeah - checking - LEDs are going to have non-zero activity - it's well under 10% (though not 0) on the overlaps)
[23:59:07] <SpeedEvil> Probably to the point that LASER is actually cheaper per watt
