[03:35:21] <jdh> any analog help around? This is a plot of mV from a pressure transducer. The downward slope is expected, the spastic samples are not.
http://www.artichoke.org/psi-mv.png
[03:41:44] <Tecan> everyone's trying to make pressure transducers these days like woody norris
[03:42:18] <jdh> ?
[03:44:18] <Theta9> what kind of filter do you have?
[03:45:00] <jdh> none :)
[03:46:06] <Theta9> what does your adc input stage look like?
[03:47:54] <jdh> 0-5vdc from the transducer to a voltage divider to teh ADC chip
[03:48:14] <Theta9> voltage divider?
[03:48:21] <Theta9> ADC is 3.3v or something?
[03:48:32] <jdh> 2.048 I think
[03:48:47] <jdh> http://www.abelectronics.co.uk/products/3/Raspberry-Pi/7/ADC-Pi---Raspberry-Pi-Analogue-to-Digital-converter
[03:48:51] <jdh> that's the board
[03:52:19] <Theta9> does the addition of a capacitor from the input the ground help?
[03:53:10] <jdh> tried a 1uF, did nothing
[03:54:33] <Theta9> how long is the cable?
[03:54:44] <jdh> the readings have a 45ish mV jitter. If I take all pressure off the transducer, the ADC reads 0VDC, but a digital voltmeter reads 40mV ish
[03:55:11] <Theta9> what is the jitter on your power supply?
[03:55:20] <jdh> about 3ft of cat5 with power on one pair, signal on the other (same ground)
[03:56:30] <jdh> dvm shows 10mV on the power
[03:57:39] <jdh> I tried a 47uF on the 12v supply also
[03:57:56] -!- Keknom has quit [Quit: Leaving.]
[04:03:51] <AR_> what is the output of the transducer, jdh
[04:03:53] <AR_> what voltage
[04:04:06] <jdh> 0-5vdc
[04:04:23] <AR_> ok
[04:04:31] <AR_> and what accuracy are you trying to get?
[04:04:49] <jdh> 1psi would be nice, 5 would be ok
[04:05:03] <jdh> but, it should be better than that
[04:05:17] <AR_> and how many mV per 1psi?
[04:06:26] <AR_> if you need to detect changes of <200mV, i suggest you add filtering
[04:06:45] <jdh> .86mV/psi
[04:07:07] <jdh> I think... 0-5800psi, 0-5vdc
[04:07:39] <AR_> holy crap
[04:07:49] <jdh> I have a differnt one (does 0.5-4.5vdc out) working on an arduino and it's fine.
[04:07:54] <AR_> and you need that whole range?
[04:08:06] <jdh> max is 4200 or so
[04:08:16] <jdh> I don't like to run my compressor higher than that
[04:08:35] <AR_> well, i know you will not get that accuracy without filtering and sheilding
[04:09:46] <jdh> I would have thought so too, but my other one reads perfectly on the other ADC.
[04:10:31] <AR_> odd
[04:11:10] <jdh> it's a different transducer. physically 2x as large
[04:11:12] <Tom_itx> what does the other one do on that adc?
[04:11:20] <Tom_itx> isolate the problem
[04:11:43] <jdh> haven't tried. different pinout on the M12 and I'd have to cap the gas line.
[04:11:48] <jdh> but, I'll try that tomorrow I guess.
[04:13:49] <Tecan> shit iForgot to pull down my pants before pooping again..hehjk

[19:15:25] <archivist> here it could be warmer than indoors

[19:17:43] <archivist> beats me how the loons fail in the snow
[19:19:33] <andypugh> To be fair, it was probably more than an inch, and it packed down into a very icy mess (being barely below freezig)
[19:19:35] <archivist> learning to drive in slippery conditions should be compulsory
[19:20:44] <andypugh> There is only so much you can do if you have a BMW, Mercedes or Jaguar with wide tyres and rear wheel drive. I have seen them doing all the right things many times, and still unable to do anything but slide down the camber.
[19:23:06] <archivist> I have never tried that sort of car in the snow, except for a mk4 cortina maybe
[19:24:56] <archivist> but usually I spend some time each winter trying out the car I have at the time, balls of fun

[20:14:12] <JT-Shop> that's what I did, put some wood screws into knobbies
[20:15:35] <JT-Shop> wow it has wheelie control "Not much has changed with the 2012 R1, but the big news is it now has a six-stage traction control system, incorporating anti-wheelie in its two most intrusive levels."

[22:42:01] <mevon> hello, Im glad to report that my implementation of ChibiOS in an arduino to Servo control L296N three steppers is making progress, I can now control 1 axis with no lag or f-error
[22:42:27] <tjb1> Anyone have any idea why my Z stalls when doing a rapid but not when doing a G1 move? Would it be that its trying to reach the max velocity too quickly versus reaching whatever feed I have set?
[22:43:07] <tjb1> I think it has something to do with my THC and then suddenly trying to move up since it is not working correctly but I don't think I have enough time/want to try lightening the Z up this weekend.
[22:43:47] -!- sumpfralle [sumpfralle!~lars@31-16-107-207-dynip.superkabel.de] has joined #linuxcnc
[22:44:48] <andypugh> tjb1: Stepper torque reduces with speed. You probably need to drop the axis max velocity
[22:45:03] <tjb1> I believe its at 2 but I will check
[22:45:43] <tjb1> I really want to keep my accel up because the touch off works much better then but have to do what works.
[22:46:04] <andypugh> Accel probably isn't the problem.
[22:46:24] <andypugh> But max velocity might be. A G0 move tried to move at the axis max-velocity

[23:06:08] <Valen> think that peak or cont torque?
[23:07:28] <andypugh> Continuous. But in oz-in for bigger numbers
[23:07:57] <Valen> thats fairly respectable i spose
[23:08:03] <Valen> what are you using to drive them?
[23:08:06] <icee> that seems expensive
[23:08:24] <Valen> theres a bigass box on the back of them, sure theres no encoder?
[23:08:47] <Valen> and 2 cables
[23:12:13] <andypugh> I asked the vendor. He says no encoder.
[23:12:39] <Valen> then whats the second box?
[23:12:48] <andypugh> Hall sensors?
[23:12:49] <andypugh> http://www.pittmanexpress.com/ecatalog/brushless-dc-motors/en/brushless-dc-motorsA0422052NC-NAXX-SP
[23:12:57] <andypugh> Is the same motor, with the encoder.
[23:13:09] <Valen> looks pretty dern similar
[23:13:42] <andypugh> But they are tiny. Maybe good for a little 3D printer for jewellry masters (my thoughts)
[23:15:56] <andypugh> Valen: Have you seen

[23:16:49] <andypugh> US$556 for a 750W motor + Dyn3H drive to suit (LinuxCNC compatible)
[23:17:10] <Valen> yeah you mentioned them before
[23:17:23] <andypugh> They seem friendly :-)
[23:17:30] <Valen> peak torque is in the same region as the kelig ones
[23:17:44] <Valen> for much cheaper
[23:17:54] <andypugh> That price includes the drive.
[23:17:58] <andypugh> Does Keling?
[23:18:06] <Valen> even if you include the drive
[23:18:17] <andypugh> Which Keling deive?
[23:18:20] <andypugh> (drive)
[23:18:25] <Valen> mesa drives
[23:19:21] <andypugh> Well, the DMM takes mains power input, which helps. Have you priced low ESR 600V caps?

[23:22:15] <Valen> she is obviously defective
[23:22:17] <ds3> is there any recommendation on a low priced, EMC2 compat (or min. work) spindle motor setup?
[23:22:35] <andypugh> What sort of spindle motor?
[23:22:38] <Valen> depends on what you mean by comptible with emc
[23:22:48] <ds3> 1/4HP
[23:22:58] <ds3> can be a bit more
[23:23:13] <Loetmichel> ds3: any motor which vfd has a 0-10V input
[23:23:19] <ds3> would be nice to have S/M03/M04 commands
[23:23:33] <ds3> Loetmichel: anyone selling motor + electronics to do that?
[23:23:44] <ds3> current motor is less then happy
[23:23:47] <Valen> I am hoping to hook up one of those chinese spindles by rs485 soon
[23:23:51] <Loetmichel> ans some small electronics which cam make a PWM to a voltage
[23:24:13] <ds3> so EMC prefers to output a PWM?
[23:24:23] <Valen> emc doesn't really have a preference
[23:24:25] <Loetmichel> IIRC yes
[23:24:30] <Loetmichel> it can
[23:24:37] <Valen> but it can do PWM out
[23:24:38] <Loetmichel> not prefers
[23:24:41] <ds3> but it is easier to setup emc to output pwm?
[23:24:51] <ds3> vs say a SPI controlled or I2C controlled DAC?
[23:25:07] <Loetmichel> ds3: why bother wit a dac?
[23:25:14] <Loetmichel> pwm is much more simple
[23:25:15] <Valen> I try to avoid analog stuff
[23:25:33] <Valen> I'd say PWM is easier than all that mucking about yes lol
[23:25:37] <ds3> don't really care... trying to see how much it'd cost for a simple solution
[23:25:54] -!- mattions has quit [Ping timeout: 264 seconds]
[23:26:07] <ds3> I can either fix my current DC motor w/manual controls or try to fit in a automatically (EMC) controlled setup
[23:26:18] <Loetmichel> ds3: any motor with a VFD with 0-10V inputs can be used for PWM
[23:26:28] <Valen> if you have a chinese spindle with VFD controller you can get a 485 (or whatever it is) chip for the spindle for a few $ and a usb > 485 dongle from deal extreme for a few more $
[23:26:36] <Loetmichel> you just need some Resistors, caps and a Operational amplifier
[23:26:42] <Loetmichel> its really simple
[23:26:57] <andypugh> In many cases the resistor and cap is all you need.
[23:27:01] <Valen> I'd use a fet and a cap and a resistor, no amp ;->
[23:27:08] <Valen> if he can tune to 0-5v
[23:27:10] <ds3> Loetmichel: who sells one cheap? small 3PH motors seem rare
[23:27:29] <Loetmichel> most of the time you can power the circuit even from the VFD, which normally has a 15V output

[23:27:51] <Valen> thats actually rather cheap
[23:28:00] <Valen> we paid almost $600 for our last one
[23:28:03] <ds3> 2KH? that is like 1.5HP
[23:28:14] <Valen> KW's are bigger than HP's
[23:28:15] <ds3> look for sub 1hp
[23:28:15] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12506
[23:28:26] <Loetmichel> 800W for less than 300 Eur
[23:28:30] <Valen> ~3HP
[23:28:42] <ds3> the mechanical parts won't handle 3HP
[23:28:55] <ds3> and I don't want to be around when the parts go flying
[23:29:12] <Valen> you don't need to push that hard
[23:29:22] <ds3> can I limit power with the VFD?
[23:29:24] <Valen> I think the most we have ever had it up to was 5A
[23:29:30] <Valen> probably best not to
[23:29:33] <Loetmichel> ds3: there are NO parts that are going to floy
[23:29:40] <Valen> http://www.ebay.com.au/itm/NEW-DIY-CNC-Router-0-8KW-800W-Spindle-Motor-1-5kw-Inverter-Drive-Driver-Kit-/121032655271?pt=LH_DefaultDomain_0&hash=item1c2e1bc1a7&_uhb=1#ht_5638wt_1398
[23:29:40] <andypugh> But for $5 you can use this circuit with any VFD:

[23:29:47] <ds3> Loetmichel: this is for a Taig mill... very small machine
[23:30:04] <Loetmichel> ... exept the mill bit shards and the workpiece
[23:30:09] <Valen> too much spindle power is not a problem I have ever heard people complain of
[23:30:13] <Loetmichel> ds3: NOT smaller than mine:
[23:30:28] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12569
[23:30:51] <Valen> http://www.ebay.com.au/itm/NEW-DIY-CNC-Router-0-8KW-800W-Spindle-Motor-1-5kw-Inverter-Drive-Driver-Kit-/121032655271?pt=LH_DefaultDomain_0&hash=item1c2e1bc1a7&_uhb=1#ht_5638wt_1398
[23:30:59] <Valen> ~1HP
[23:31:03] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12578
[23:31:18] <ds3> Loetmichel: hmmm that came from ebay?
[23:31:23] <Loetmichel> Valen: 1.5kW is more loke 2 HP
[23:31:34] <Valen> 1.5 VFD .8motor
[23:31:34] <Loetmichel> ds3: the Motor? yes
[23:31:35] <ds3> 800W is a bit over 1HP, IIRC
[23:31:36] <andypugh> That link of mine (which got rather lost in the URL flood) can be fitted into the cable, or at the VFD. Just solder components to the chip legs.
[23:31:45] <ds3> andypugh: I like your link
[23:31:56] <ds3> let me find out what package that chip is in
[23:32:05] <Valen> though as far as I'm aware these vfd's don't take in 0-10v
[23:32:06] <Valen> ?
[23:32:15] <Loetmichel> Valens link is exactly mine
[23:32:50] * Valen bets the only difference in the vfd power outputs is how much steel they pack in the back of the controller to make it feel heavier
[23:33:01] <ds3> SOIC... I like
[23:33:02] <Loetmichel> andypugh: right: i said it isnt much work ;)
[23:33:12] <ds3> I rather not deal with ebay
[23:33:18] <ds3> but I'll look into that
[23:33:28] <Loetmichel> Valen: no, the smaller ones have a smaller heatsink-fan ;-)
[23:33:29] <ds3> Loetmichel: how much was it?
[23:33:36] <andypugh> That circuit isolates the P-port (or Mesa/Pico) PWM from the VFD control voltage. The voltage the VFD sees is a proportion of it's own control voltage. As far as the VFD s concerned, it sees something like a potentiometer.
[23:33:48] <Loetmichel> ds3: less than 300 eur for spindle AND VFD
[23:33:59] <ds3> andypugh: I assume it takes advantage of the slow response of the isolator to do some filtering?
[23:34:17] <ds3> Loetmichel: hmmm that's like $500 US.
[23:34:20] <Loetmichel> ds3: no, The RC does the filtering
[23:34:21] <andypugh> No, that's the cap and resistor.
[23:34:30] <Loetmichel> ds3: $400 more likely
[23:34:38] <Valen> the one i posted was in $au which is ~= $us atm
[23:35:03] <Loetmichel> but germany tends do be a bit more expensive than .us
[23:35:20] <andypugh> The only important point is that that particular Opto is a Totem-pole output, so it sinks current when off, and sources when on. A typical Opto doesn't.
[23:36:44] <ds3> Loetmichel: is it a PM DC motor or 3PH?
[23:36:53] <andypugh> 3P
[23:37:04] <Valen> do be aware too though that many parallel ports wont push enough current for many optos
[23:37:33] <Loetmichel> 3ph
[23:37:53] <ds3> that is a very close race with a sherline motor
[23:38:05] <ds3> guess it comes down to which one can be wired up easier
[23:38:32] <Loetmichel> andypugh: ... abd the opto has a Cmos output rather than TTL so it can cope with the 15V ;-)
[23:39:53] <andypugh> That chip needs typically 2.2, max 5.5 mA current. I did look very long and hard for the exact right chip.
[23:40:48] <andypugh> (it can actually handle 25V on the output side)
[23:40:56] <Valen> thats a pretty nice chip
[23:41:24] <ds3> doesn't silabs make similar isolators?
[23:44:42] <andypugh> I wonder if it is worth getting a batch of PCBs made up and flogging PWM to VFD convertors on that eBay. I reckon I coulf make $5 or $6 a week.
[23:46:50] <jdh> I'll pay us$10 for one (shipped)
[23:48:03] -!- rob_h [rob_h!~rob_h@5e029598.bb.sky.com] has joined #linuxcnc
[23:48:05] <Tom_itx> a guy in #avr does pcbs from china
[23:48:12] <Tom_itx> pretty reasonable
[23:50:52] <andypugh> I have used Seeed. They would charge $10 for 10 boards, and cheaper for more.
[23:51:14] <ds3> hmm
[23:53:51] -!- ybon has quit [Quit: WeeChat 0.3.8]
[23:55:44] <Loetmichel> andypugh: woha! a whopping $6? GO for it!
[23:56:01] <andypugh> So far I am impressed. Quality is good. You get resist and screen print and plating. It beats making them yourself by a huge margin if you can wait 10 days.
http://www.seeedstudio.com/depot/fusion-pcb-service-p-835.html?cPath=185
[23:56:38] <Loetmichel> hmm.
[23:57:56] <ds3> if you are doing a PCB, can you throw in pads for a reverseing relay?
[23:58:00] <Loetmichel> i hve some local PCB manufacturers wich make a 100*160mm 2 layer card with gold and resist for about $50. and 10 pcs for about $100
[23:58:16] <andypugh> I might do it anyway, just because there doesn't seem to be anything out there simple and cheap enough.
[23:58:19] <Loetmichel> much more expensive but faster
[23:58:53] <Loetmichel> ds3: reversing ralay?
[23:58:54] <andypugh> ds3: And suddenly we have feature-creep....
[23:58:57] <Loetmichel> for what?
[23:58:59] <ds3> andypugh: if you have provisions for a relay, I'd be interesting in buying one
[23:59:09] <ds3> Leotmichel: I am seeing cheaper DC motors
[23:59:21] <ds3> andypugh: no need to install it...just pads
[23:59:24] <Loetmichel> the VFD have 2 inputs for CW and CCW
[23:59:47] <ds3> trying to confirm that the sherline DC motor unit takes 0-10V.. if so, it just needs a relay and I have it all
[23:59:50] <Loetmichel> and / or a "run" and a " Direction" input
[23:59:54] <ds3> and it is like $230USD
