#emc | Logs for 2010-05-15

[00:06:09] <PCW> BSPI is may name for the specific buffered SPI host side hardware
[00:06:23] <PCW> (look in regmap)
[00:08:33] <PCW> (my name)
[00:13:53] <andypugh> Yes, I think I saw that in passing, but was looking for something else, so moved on
[00:37:02] <PCW> loong day time to go homewards...
[00:37:03] <PCW> bye andy/all
[01:04:12] <MarkusBec_away> MarkusBec_away is now known as MarkusBec
[01:11:42] <MarkusBec> MarkusBec is now known as MarkusBec_away
[02:02:09] <atmega> anyone know why I get an Unknown m code used on M98 P111
[02:05:21] <andypugh> I am not sure EMC uses M98
[02:07:51] <andypugh> If you want to call a sub-program, that functionality is in O <call>
[02:12:23] <atmega> cool, thanks.
[02:12:29] <atmega> nice thing about standards, there are lots.
[02:13:55] <andypugh> I think all of "O" and M98 are technically extensions to RS274D
[02:15:49] <andypugh> RS274D was approved in 1980, it has been diverging since.
[02:49:18] <atmega> can you do a MSG or somethign that prompts for variable entry?
[02:49:27] <cradek> nope
[03:04:39] <atmega> if I did a G41 cut with the wrong tool selected (zero diameter) the resulting cut would be what was specified + cutter radius?
[03:05:02] <cradek> G41 on a zero diameter tool has no effect
[03:05:23] <cradek> cutter comp does not turn on - the tool takes the programmed path
[03:06:03] <atmega> so what I really ended up cutting was the programmed path + radius
[03:07:06] <cradek> I guess, something like that
[03:56:46] <ries> hey all, where can I find about the hard ware needed for auto-homing? I do find the sequences, but I am not sure what is expected from my switches
[03:58:06] <atmega> how to wire them?
[04:00:41] <ries> Athlocatle: yeaa and where to put the switches, also I have a block of 8cm along each axis, and I wonder if i can use that to put my microswitch against
[04:00:54] <ries> I think they need to be wired parallel...
[04:01:35] <atmega> if you only use one pin, you would parallel them for NO switches
[04:01:44] <Athlocatle> ??
[04:01:45] <atmega> or series for NC
[04:01:59] <atmega> tab completion I presume
[04:02:47] <ries> so I can put them like 15cm from each home position, and the size of my 'block' doesn't really matter?
[04:04:54] <atmega> afaik, you can put the switches anywhere and just tell EMC where it is relatively
[04:05:16] <atmega> I have only done one setup, and I combined home with (-) limit
[04:07:08] <ries> ic ic
[04:14:05] <ries> atmega: what happens when the auto home cannot find the home switches? can I instruct it to step after let's say 300mm of searching?
[04:19:41] <atmega> that can't really happen with my setup
[04:19:58] <atmega> so, no idea.
[04:24:55] <ries> ic...
[04:25:11] <ries> I was planning, for now to make 3 switches, but may be I should attach all 6
[04:29:17] <atmega> My Z has only the one home switch, but it is (almost) at the end of (-) travel so I just have it home negative
[04:47:35] <cradek> a home switch should divide the travel into two sections: one with the switch on, the other with the switch off
[04:48:11] <cradek> a home switch that divides travel into three sections is not good, because emc can not tell which way to travel to find the switch
[04:48:25] <cradek> putting a small cam at the end of travel is a common way
[07:31:37] <ries_> ries_ is now known as ries
[07:44:36] <elmo40> atmega: what version of kMotion do you have?
[09:11:47] <MattyMatt> neat, sorted the G41 lead in, and I can still plunge. If I'd used G42 that would have been a 100% success.
[09:14:18] <MattyMatt> I guess I ought to put a button in for plunging? with some materials/cutters you'd prefer to slope in along the cut?
[09:20:23] <piasdom> g'mornin all
[09:22:58] <micges> hi
[09:33:13] <piasdom> (i asked before) how do i put a "home all" button in axis?
[09:34:11] <MattyMatt> there's a menu for it, dunno how to add buttons tho
[09:34:38] <piasdom> i did what was said and it added the home all button, but took away the home each axis button
[09:34:46] <MattyMatt> I find I need the Unhome All button just as much, to get it to home in the first place :)
[09:35:17] <MattyMatt> no handwheels
[09:35:33] <piasdom> no one should have a unhome :)
[09:37:25] <MattyMatt> home switches would be nice
[09:38:21] <micges> piasdom: home all button will show when you have defined home sequence in ini file, home each axis is in machine menu
[09:38:26] <MattyMatt> and trying to mill vice/clamps sensor wouldn't go amiss
[09:38:58] <MattyMatt> on a machine made for wood
[09:39:19] <piasdom> i know, but it onlt had home all and i couldn't home z without homing xy
[09:39:40] <piasdom> *only
[12:04:11] <piasdom> if it put home all = x=0,y=0,z=0 in the "Trajectory planner section", would that give me another button?
[12:05:43] <JT-Dev> try it
[12:08:33] <piasdom> k :)
[12:17:16] <frallzor> did a little update and now emc wont boot without an error, saying it can not find certain things, like axis
[12:18:54] <JT-Dev> what kind of update?
[12:19:10] <frallzor> the ones that updates via updater
[12:19:15] <frallzor> in ubuntu
[12:19:42] <frallzor> 2.3.0 became 2.3.4
[12:19:59] <frallzor> but I know the issue now
[12:20:04] <JT-Dev> ok
[12:20:23] <frallzor> for some reason it works after stepconf
[12:22:16] <JT-Dev> frallzor: you should be at 2.3.5 if you updated with the synaptic package manager
[12:22:41] <frallzor> well I was a bit behind on that
[12:22:48] <frallzor> I bet itll be 2.3.5 if I do it again
[12:23:25] <frallzor> oh ffs
[12:23:36] <frallzor> now the config for the gamepad wont work
[12:23:47] <frallzor> its the thing messing it up =/
[12:25:20] <JT-Dev> nothing is suppose to break between 2.3.0 and 2.3.5 only if you go to 2.4.n
[12:26:11] <frallzor> 2.4.n?
[12:27:49] <JT-Dev> any 2.4 version might have new things that might break any 2.3 config
[12:28:23] <JT-Dev> but nothing is suppose to break between any 2.3 version like 2.3.0 2.3.1 etc
[12:28:59] <JT-Dev> n=any number
[12:29:37] <frallzor> f f f f f
[12:29:49] <frallzor> why wont the config with the pad work now
[12:30:12] <frallzor> there isnt anything specific in any file.. that should mess up
[12:32:13] <piasdom> no :(
[12:33:02] <frallzor> http://pastebin.com/iSEuRZxq maybe this log makes sense to someone =)
[12:37:01] <JT-Dev> look at line 525
[12:38:08] <frallzor> aha mhm
[12:38:19] <frallzor> is that suddenly changed?
[12:38:31] <frallzor> since that exact same line worked in 2.3.0
[12:39:21] <JT-Dev> is you game pad plugged in?
[12:39:28] <JT-Dev> your
[12:39:35] <frallzor> yup
[12:44:13] <cliffb> Morning everyone... I am looking from some feedback, I have been working on a remote gui interface to use with emc. Here is two screenshots so far... http://www.powerautomation.net/mainpage/images/CNC/qtemc_axis.png http://www.powerautomation.net/mainpage/images/CNC/qtemc_help.png
[12:46:48] <frallzor> any ideas on what is the mess JT-Dev? =)
[12:47:00] <cliffb> I used qt to write it, My goal is to be able to use qt desiner, so a user can layout the view as he sees fit, connect the widgets to there pins,params or signals and then open it without any need for compiling.. kinda like pyvcp but being able to drag and drop where you want..
[12:47:22] <SWPadnos> cliffb, rock on :)
[12:47:51] <cliffb> It runs over TCP and will work on windows, mac and of couse linux...
[12:48:14] <cliffb> Think this is something people will use??
[12:48:25] <SWPadnos> are you using some qt/X tcp thing?
[12:48:31] <SWPadnos> yes, I'll bet people would use it
[12:48:37] <cliffb> no... it uses halrmt....
[12:48:48] <SWPadnos> ok. you may want to look at using NML directly
[12:49:10] <SWPadnos> that's the "standard" way of doing remote (or local) GUIs
[12:49:53] <SWPadnos> there was some work done about 5 years ago on a set of qt<->NML widgets, but we never got very far
[12:50:15] <cliffb> If I do that I would have to re-invent the wheel and make both a local and remote program.. for most purposes.. halrmt seems find...
[12:50:33] <SWPadnos> no, NML is how the GUIs talk to the task manager
[12:50:38] <SWPadnos> EMC task that is
[12:51:36] <cliffb> Do you have to be running on the same host to issue a NML command to EMC?
[12:51:41] <SWPadnos> no
[12:52:06] <SWPadnos> but you can be, which removes a layer of complexity for people using one computer
[12:52:19] <cliffb> Cool.. that allows for a lot integration...
[12:52:40] <SWPadnos> yep. NML is the way to go, IMO (that's what it's there for)
[12:53:54] <cliffb> I'll do some more reading.. I have wrote the back end which reads the state and issues signals so it could be changed easily.. I already saw many issues only having halrmt commands to work with.
[12:54:15] <SWPadnos> yep. I'll bet error notification is one :)
[12:54:19] <SWPadnos> and status updates
[12:55:06] <cliffb> ... Yeah.. sending a crap load of text every update really hogs bandwidth...
[12:55:20] <cliffb> You know where I might find that qt source you mentioned
[12:55:26] <SWPadnos> NML sends a fair amount of status, but it's everything
[12:55:52] <SWPadnos> I'll look around for it. I think we stuck it on linuxcnc.org, but I don't know where
[12:56:20] <cliffb> As a side question, who has admin to the site?
[12:56:23] <SWPadnos> there's also source for the Smithy UI "EZTrol" somewhere - that's also qt based
[12:56:34] <SWPadnos> depends on which part of the site you're talking about
[12:57:16] <cliffb> I would just like to see a wiki link at the top.. not huge but it's a pretty major source of info
[12:57:19] <SWPadnos> the forums and stuff are mostly admin'ed by alex_joni and jt-something
[12:57:28] <JT-Hardinge> LOL
[12:57:33] <SWPadnos> ok, I think that would be Alex
[12:57:42] <SWPadnos> jt-whichever :)
[12:57:56] <cliffb> Although I guess i can scroll down
[12:58:00] <JT-Hardinge> at least you know where I'm at lol
[12:58:29] <SWPadnos> the wiki link is about 2 inches below the top link bar on my screen
[12:58:40] <JT-Hardinge> mine too
[12:58:43] <cliffb> lol
[13:02:22] <frallzor> JT-Hardinge think speed has changed in 2.3.4? =)
[13:03:21] <JT-Hardinge> speed?
[13:03:37] <frallzor> that pin or whatever its called
[13:03:52] <frallzor> its "name"
[13:04:15] <JT-Hardinge> no, I'm sure no EMC pin names changed from 2.3.0 to 2.3.4 AFAIK
[13:05:34] <frallzor> anyone might know why this happens in 2.3.4 but not in 2.3.0 for me? 526.custom_postgui.hal:31: pin 'halui.jog-speed' does not exist
[13:07:37] <Xavier_H> Hi all
[13:08:46] <JT-Hardinge> frallzor: it is in 2.4...
[13:09:22] <frallzor> what is it in 2.4? cant hurt to try =)
[13:10:17] <JT-Hardinge> it is the same halui.jog-speed
[13:10:31] <frallzor> ah you mean it wasnt changed in 2.4 =)
[13:10:50] <frallzor> then its logical it isnt changed in 2.3.4 either
[13:11:12] <frallzor> wonder why I didnt get 2.3.5 though like you said
[13:13:08] <frallzor> possible to get 2.3.5 somehow besides via synoptic?
[13:13:44] <JT-Hardinge> dunno why but you might need to reload the something or another files in synaptic
[13:15:46] <JT-Hardinge> yea open up synaptic and the big reload button
[13:16:09] <SWPadnos> ... after changing the emc2 repositories back to 2.3
[13:16:29] <SWPadnos> you won't see 2.3.x with the 2.4 repos in the sources list
[13:16:39] <JT-Hardinge> I think he is still on 2.3
[13:16:45] <frallzor> well I have both
[13:16:55] <frallzor> 2.4~pre too
[13:17:03] <SWPadnos> ok, if you have both repos listed then you will see all of the packages
[13:17:13] <frallzor> I guess I dont then
[13:17:26] <frallzor> 2.3.4 is the newest according to synaptic
[13:17:38] <SWPadnos> ok, then you need a reload
[13:18:31] <frallzor> now 2.3.5 shows
[13:18:32] <frallzor> goodie
[13:19:55] <frallzor> ill let it update while Ill go make a sandwich
[13:30:40] <frallzor> all done, exciting
[13:34:13] <frallzor> still same error
[13:36:56] <JT-Hardinge> logger_2 bookmark
[13:37:17] <JT-Hardinge> I guess that ain't the right word :/
[13:37:29] <SWPadnos> you need a comma (or maybe a colon)
[13:37:39] <SWPadnos> logger_2, bookmark
[13:37:39] <SWPadnos> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-05-15.txt
[13:37:47] <JT-Hardinge> ah ok thanks
[13:37:49] <frallzor> I hate emc right now =D
[13:37:52] <SWPadnos> logger_2, help
[13:39:23] <SWPadnos> bbl
[13:40:00] <JT-Hardinge> frallzor: look at line 442 too, not related to this problem but a problem too
[13:41:03] <frallzor> cna you paste it for me? I cleared the wrong window
[13:41:06] <frallzor> *can
[13:41:18] <JT-Hardinge> http://pastebin.com/iSEuRZxq
[13:41:21] <frallzor> ty
[13:41:43] <frallzor> yeah thats nothing, happens at every startup
[13:41:48] <frallzor> never during milling
[13:42:00] <JT-Hardinge> you didn't read it well did you?
[13:42:10] <JT-Hardinge> this helps too with dmesg http://www.linuxcnc.org/docview/html//common_Linux_FAQ.html#r1_6_6
[13:43:34] <JT-Hardinge> #
[13:43:36] <JT-Hardinge> [ 544.926068] This Message will only display once per session.
[13:44:30] <JT-Hardinge> [ 544.926071] Run the Latency Test and resolve before continuing.
[13:44:54] <frallzor> well as I said, it happens no matter what at every startup =)
[13:45:03] <frallzor> but during milling when just doing that its all fine
[13:45:27] <JT-Hardinge> it happens all the time I'm sure but you only get ONE message
[13:45:55] <JT-Hardinge> if you got a message everytime it happed you would get a flood of messages and would not be able to stop them
[13:46:07] <frallzor> if it did occur all the time wouldnt I loose step all the time then?
[13:46:28] <JT-Hardinge> no but your steps would not be on time
[13:47:23] <frallzor> meaning?
[13:49:53] <JT-Hardinge> your step output would not be smooth I guess it a way to describe it
[13:50:03] <JT-Hardinge> http://www.linuxcnc.org/docview/html//common_Stepper_Diagnostics.html#r1_2_2
[13:50:32] <JT-Hardinge> I guess it would run like mach then
[13:51:59] <frallzor> ill try a higher number then =)
[13:52:21] <frallzor> but the odd issue with speed is still
[13:53:22] <JT-Hardinge> clear the dmesg and run again then post the dmesg to pastebin again
[13:53:49] <frallzor> rgr
[13:53:51] <JT-Hardinge> like it shows here http://www.linuxcnc.org/docview/html//common_Linux_FAQ.html#r1_6_6
[13:56:35] <frallzor> run emc before dmesg?
[13:56:43] <frallzor> or just do it? =)
[13:56:57] <JT-Hardinge> yes, clear dmesg, run emc then do dmesg
[13:57:22] <frallzor> hmmm
[13:57:34] <frallzor> im pretty sure I altered all files for the gamepad use
[13:57:41] <frallzor> and it booted now
[13:57:55] <JT-Hardinge> EMC runs now?
[13:58:18] <frallzor> ill have to doublecheck if all changes are there
[13:58:29] <frallzor> odd
[13:59:09] <frallzor> its all in the files and it just booted
[13:59:25] <frallzor> isnt that funky?
[14:00:28] <frallzor> the world is a funny place to be in
[14:00:40] <JT-Hardinge> now you need to run the latency test for an extended time to find your results
[14:01:37] <frallzor> changed it to 20000
[14:01:52] <frallzor> so far no complaints
[14:02:01] <JT-Hardinge> good
[14:02:12] <frallzor> wonder if that had anything to do with this issue....
[14:02:19] <frallzor> no complaints and now its working
[14:02:36] <JT-Hardinge> Yea!
[14:02:56] <frallzor> but still, same with 2.3.0 and there it did work =)
[14:03:04] <frallzor> maybe some feature to prevent failure
[14:03:39] <frallzor> but im inside now, so I can test it atm so Ill see if it really works in a bit
[14:03:44] <frallzor> *cant test
[14:04:18] <frallzor> but at least I got wireless on it too now so I can camp by the computer and still have internet now =)
[14:05:08] <JT-Hardinge> I know how that is I struggled for while to get my shop and house LAN and Internet working and playing nicely
[14:05:29] <frallzor> I had to use ndiswrapper but It was surprisingly easy
[14:05:48] <frallzor> not even a frown upside down to get it going =P
[14:05:59] <JT-Hardinge> I had to run another cat5e cable from my shop to the beer cave
[14:22:20] <frallzor> aha
[14:23:00] <frallzor> if stepconf say like max step rate = eg 30000
[14:23:20] <frallzor> does it mean one could use 5 steppers that have a max rate of 6000 then?
[14:23:36] <frallzor> or is it 30000 per stepper?
[14:27:10] <frallzor> or per axis?
[14:28:07] <JT-Hardinge> per stepper
[14:28:34] <frallzor> lets say you have 2 on X, count as 2 or one?
[14:34:58] <JT-Hardinge> I'm not sure I understand the question
[14:35:26] <frallzor> I would think that 2 stepper getting exactly the same orders would share the step rate
[14:35:40] <frallzor> so its not 2x rate but 1x
[14:36:27] <JT-Hardinge> yes the step rate is the same for all
[14:37:15] <frallzor> so if I have 2x for x, 1x y 1x z its the stepper rate x4?
[14:37:27] <frallzor> which should preferably be lower than the base?
[14:39:22] <JT-Hardinge> I really not sure what we are talking about now :)
[14:40:40] <frallzor> one enters the info in the basic machine information and get a Max steprate right?
[14:41:27] <frallzor> if this is 30000Hz does it mean i can use 30000Hz per stepper? or max steprate / number of steppers = max per stepper
[14:41:30] <JT-Hardinge> yes you enter in the latency test result and the max step rate is calculated from that
[14:43:03] <JT-Hardinge> the max step rate is just that and has nothing to do with how many steppers you have
[14:43:36] <frallzor> well the steppers have a rate at its max speed too
[14:43:58] <JT-Hardinge> what do you mean?
[14:44:29] <frallzor> "Pulse rate at max speed: 6000Hz"
[14:44:59] <JT-Hardinge> that is limited in your max velocity setting
[14:45:05] <frallzor> I though that this multiplied with the number of steppers and should be equal or less to the max steprate as in 30000
[14:45:06] <JT-Hardinge> in/with
[14:45:38] <JT-Hardinge> the number of steppers has nothing to do with the max step rate
[14:46:37] <frallzor> no, but doesnt the steppers own max rate has something to do with it?
[14:47:30] <JT-Hardinge> no
[14:47:53] <JT-Hardinge> I assume you mean the stepper driver board max pulse rate
[14:48:00] <frallzor> yup
[14:48:15] <frallzor> or nah, the info in step conf
[14:49:02] <JT-Hardinge> the max step rate in the basic page is how fast you can generate pulses not how fast you will go based on accel and vel settings
[14:49:38] <frallzor> ah
[14:50:08] <JT-Hardinge> go to an axis page and play with the numbers and watch the pulse rate at max speed number
[14:51:32] <JT-Hardinge> if your driver has a 6000Hz speed limit you make sure you don't have a velocity gear ratio that exceeds that
[14:53:20] <frallzor> 350 kHz maximum Step pulse frequency this means im pretty safe?
[14:53:25] <frallzor> =)
[14:53:40] <DaViruz> or pretty optimistic
[14:53:46] <frallzor> gecko =(
[14:53:56] <frallzor> they lie?
[14:54:08] <frallzor> data on the driver btw =)
[14:54:13] <frallzor> not settings in emc
[14:54:15] <DaViruz> no but the paralell port will never handle that
[14:54:16] <DaViruz> oh
[14:54:16] <DaViruz> ok
[14:54:29] <frallzor> so my 6k should be pretty decent
[15:51:51] <jlmjvm> jepler r u here?
[15:52:43] <jlmjvm> trying to add an index for homing on my mill
[15:55:01] <jlmjvm> does the new stepconf have an option for that?
[15:57:25] <JT-Dev> yes
[15:57:58] <JT-Dev> you running 2.4?
[15:58:10] <jlmjvm> no,2.2 i think
[15:59:03] <JT-Dev> wow that is old
[15:59:21] <jlmjvm> like me unfortunately
[15:59:27] <JT-Dev> me too
[15:59:48] <jlmjvm> it was when stepconf first came out
[16:00:49] <jlmjvm> is 2.4 already in a ubuntu download?
[16:01:35] <JT-Dev> it's an upgrade from 2.3 but not on a live cd
[16:01:44] <jlmjvm> k
[16:01:55] <JT-Dev> I meant the new pncconf
[16:02:01] <JT-Dev> I'll check the stepconf
[16:02:10] <jlmjvm> k,thanks
[16:03:34] <JT-Dev> yea, no index as stepconf is for steppers and they normally don't have encoders
[16:04:19] <jlmjvm> thats what i have,steppers with encoders
[16:04:50] <jlmjvm> works very well,but would like to add the index
[16:06:29] <JT-Dev> you might take a look at the sample configs and pull the index part from one and add to yours
[16:06:42] <jlmjvm> lemmee see
[16:08:59] <cradek> currently, you can't home to index with steppers unless you are running them with a velocity mode stepgen and pid
[16:11:30] <JT-Dev> that's good to know
[16:12:35] <jlmjvm> yep,good to know
[16:13:54] <atmega> I just cut my first useful thing on my router!
[16:14:12] <jlmjvm> i thought i remembered Alex telling me it would,but that was couple years ago
[16:14:24] <pcw_home> Is there any reason the software stepgen cant home to index?
[16:15:43] <pcw_home> (assuming homing moves could be slow enough that index can be reliably detected)
[16:17:03] <jlmjvm> be back in a few
[16:18:18] <renesis> open loop step can home with limit switches tho right
[16:18:22] <renesis> RIGHT!??!?!
[16:18:42] <renesis> hope so
[16:20:39] <JT-Dev> yea
[16:27:54] <frallzor> just tried the system, works fine with 2.3.5 =)
[16:38:26] <JT-Hardinge> yea frallzor
[16:39:19] <frallzor> now I just need 2 grand and im in business! :P
[16:39:44] <JT-Hardinge> Monopoly money?
[16:39:51] <frallzor> real money =(
[16:40:21] <JT-Hardinge> your supposed to save the money first then start the business :P
[16:41:32] <frallzor> boring :P
[16:55:41] <frallzor> oh a bit cheaper than I thought
[16:55:57] <frallzor> still expensive though :P
[16:56:05] <JT-Hardinge> what is?
[16:56:17] <pjm> btw thanks dev's for EMC 2.4, working very nicely here!
[16:56:37] <JT-Hardinge> cool
[16:57:50] <frallzor> JT-Hardinge aspire, but the difference is like a fart in space =)
[17:03:08] <jlmjvm> back from lunch
[17:05:42] <JT-Hardinge> * JT-Hardinge has a shot of Nyquil and a Corona in preparation for a nap and can't wait for this head cold to go to someone else
[17:06:47] <jlmjvm> cradek,can my mill be run with a velocity mode stepgen and pid?
[17:52:32] <piasdom> if i have g43 m6 t3 in my code and t3 -1 in tool table shouldn't the zero be moved down. i had t3 +1 and it was added to my zero. running an inch about zero. is that right?
[17:53:06] <piasdom> should the -1 be ran 1 in under my zero?
[17:56:38] <jlmjvm> what kinda machine you running
[17:58:13] <cpresser> i am running the; however there seem to be some issues: i cant load the module rtai_sched and rtai_lxrt at the same time, since they both export the same symbol 'lxrt_prev_task'.
[17:58:18] <cpresser> any ideas how to fix this?
[17:59:34] <piasdom> sherline
[18:00:08] <piasdom> sherline tabletop mill
[18:00:12] <frallzor> lack of stuff to mill, so im making a second deer scene :P
[18:01:29] <jlmjvm> how did the first 1 look
[18:02:04] <piasdom> i ran it in the air, ran an inch about my z home
[18:02:45] <piasdom> then i put a neg sign and it ran at my z home
[18:03:20] <piasdom> i just changed the tool table to see the differance
[18:05:55] <frallzor> jlmjvm me?
[18:10:48] <jlmjvm> frallzor:yes you
[18:11:57] <frallzor> http://www.pici.se/p/aBwpEvRwD/ turned out pretty ok =)
[18:12:06] <frallzor> making same again but will treat it differently
[18:13:13] <jlmjvm> excellent work
[18:14:14] <jlmjvm> brb
[18:45:08] <mikegg> would 125 VDC be too much juice for an 850 in-oz stepper?
[18:45:41] <SWPadnos> what's the voltage rating of the stepper?
[18:45:49] <mikegg> i don't know
[18:46:02] <SWPadnos> then yes, it's probably too much :)
[18:46:06] <SWPadnos> what about the drive?
[18:46:18] <mikegg> still shopping for a drive
[18:46:32] <mikegg> was thinking about buying a gecko, but they top out at 80 VDC
[18:47:07] <SWPadnos> I had a couple of big-ass steppers, actually "synchronous/stepper" motors, which were 1100 oz-in or could be run directly from 120AC
[18:47:19] <SWPadnos> they were huge, about 40 pounds each
[18:47:23] <mikegg> wow
[18:47:40] <SWPadnos> anything "small" is probably not going to take that
[18:48:16] <SWPadnos> why do you wonder about 125VDC?
[18:49:28] <jlmjvm> hello SWPadnos
[18:49:32] <SWPadnos> hi
[18:49:35] <mikegg> I've got a servo drive that is blown, but the DC power supply is still good
[18:49:55] <mikegg> trying to think of some way to make use of it
[18:50:26] <SWPadnos> hmm
[18:50:47] <mikegg> I guess if I wanted to step the 125 VDC down to 80 VDC i would just need to get a bunch of those big power resistors with the heat sinks?
[18:51:25] <SWPadnos> that would be about the worst thing I can think of :)
[18:51:33] <SWPadnos> you'd need a lot of fans in that case
[18:51:46] <mikegg> heh, glad I asked
[18:51:53] <cradek> submerging them in vats of vegetable oil would keep them cool enough
[18:52:02] <SWPadnos> better to get a 2:1 transformer and run the supply at 62.5V (or something)
[18:52:08] <SWPadnos> and you could deep-fry chickens or something too
[18:52:21] <mikegg> like the sound of that!
[18:52:33] <SWPadnos> hard to keep the metal bits out of the soup though
[18:53:13] <mikegg> alright well I guess I'm shopping for a PS and a drive
[18:53:54] <SWPadnos> and motor specs. start with those
[18:54:35] <mikegg> argh, I know! there is no visible label on the motor
[18:55:03] <mikegg> It's the Z-axis on one of these bad boys http://www.smithy.com/product_specs.php?cid=11&scid=16&pid=1006
[18:55:38] <mikegg> it says tested at 110 VDC
[18:55:40] <mikegg> 6 amps
[18:56:33] <SWPadnos> then I'd say that 125VDC is out of spec
[18:56:41] <SWPadnos> and 110 probably is too, but they tried it
[18:56:56] <SWPadnos> you could email them and ask
[18:57:38] <mikegg> I could get like a 125 VAC step down transformer and put it on the AC input to my spare DC power supply... No?
[18:58:23] <SWPadnos> uh
[18:58:35] <SWPadnos> dunno actually
[18:59:22] <mikegg> depends on how the DC power supply works?
[19:00:18] <SWPadnos> yes. if it's a bulk supply (transformer and capacitor), then the output V will be proportional to the input V
[19:00:52] <SWPadnos> if it's a regulated supply, especially a switching supply, then it may not work at all with such a low input, or it may still try to make the full output voltage regardless
[19:01:29] <mikegg> not a transformer and capacitor. has a rectifier and some transistors
[19:01:39] <mikegg> wait
[19:01:45] <mikegg> has capacitors too
[19:06:31] <frallzor> yeeey first time i lose a shitload of steps
[19:06:52] <frallzor> gg 2.3.5 =(
[19:08:51] <mikegg> thanks fellas, I gotta run.
[19:15:56] <jlmjvm> http://pastebin.com/8uzQwQ9u
[19:18:28] <jlmjvm> Steve if get a chance can you take a look at my config,trying to enable index
[19:20:17] <frallzor> how odd I lost steps, only difference is 2.3.0 > 2.3.5 and I increased base thread from 15000 > 28000 just for fun
[19:22:47] <cradek> increasing base thread will probably make your step timings worse
[19:22:52] <cradek> I recommend changing one thing at a time
[19:23:02] <frallzor> really?
[19:24:10] <frallzor> I had no issus but JT commentend on my emc complaining about delay at start
[19:24:12] <frallzor> so I changed
[19:24:33] <frallzor> *issues
[19:24:44] <cradek> maybe try an in-between value
[19:25:02] <frallzor> 20k seems fair
[19:30:33] <frallzor> too bad I messed up my last piece of hardwood with it =)
[19:35:58] <cradek> if you're that close to the edge (and you have verified your machine moves freely everywhere) you should probably reduce your vel and accel both by 10%
[19:36:38] <frallzor> well it has worked fine before I changed =)
[19:36:56] <frallzor> I was only going at it at 5000mm/min too
[19:37:56] <SWPadnos> jlmjvm, lines 34 and 35 in that file will not quite do what you want, and I think 35 may actually error
[19:38:38] <SWPadnos> also, index and index-enable aren't the same thing
[19:38:47] <frallzor> Ill just go back to 15-16000 that worked =)
[19:39:07] <SWPadnos> index-enable most likely shouldn't be attached to a physical port pin, that's an internal signal between the motion controller and the encoder counter component
[19:39:50] <SWPadnos> so my suggestion (after reading all relevant parts of the manual, looking at sample configs, etc :) ) is:
[19:40:17] <SWPadnos> uncomment line 27 so that the physical index pin is connected to the encoder component
[19:40:44] <SWPadnos> replace lines 34 and 35 with one net line that connects the encoder and motion controller like so:
[19:41:21] <SWPadnos> net index-enable-0 axis.0.index-enable encoder.0.index-enable
[19:44:14] <jlmjvm> thanks,will give that a try
[19:44:35] <SWPadnos> is it actually a spindle encoder (as line 34 implies)?
[19:45:16] <jlmjvm> no,that was something i got from stepconf for an example
[19:45:20] <SWPadnos> ok
[19:46:55] <eric_unterhausen> eric_unterhausen is now known as EricKeller
[19:50:40] <jlmjvm> that appears to work,emc will start without error
[19:51:24] <jlmjvm> will wire it in and test in a bit
[19:54:48] <jlmjvm> thanks for the help
[19:56:08] <jlmjvm> bbl,gotta power down for some wiring

[21:04:19] <cradek> haha
[21:04:35] <cradek> hope it was worth it
[21:05:13] <MattyMatt> it got the url in the first spam. impressive
[21:05:45] <cradek> heh, they say they have "unique" prices
[21:05:57] <archivist> but automation was waiting to kick it :)
[21:06:21] <cradek> seems like freenode is pretty darn good
[21:06:26] <archivist> its been in another chan under another nick too
[21:06:46] <MattyMatt> freenode should syndicate it
[21:07:00] <MattyMatt> maybe not freenode, efnet could tho
[21:08:00] <MattyMatt> I don't mind an occasional word from my sponsors :)
[21:09:43] <MattyMatt> 59.5mm x 46.8 when it should be 60x47. this is good enough for my woodworking needs
[21:10:26] <MattyMatt> so BlenderCAM is basically operational
[21:10:40] <eric_unterhausen> eric_unterhausen is now known as EricKeller
[21:11:28] <MattyMatt> blender GUI doesn't seem to have a way to show disabled buttons, so I've got too many dead ones to release atm
[21:20:33] <JT-Hardinge> * JT-Hardinge rewires the fork so it works with mux16
[21:22:43] <Jymmm> an electric fork?! You have an electric spoon too?????
[21:23:04] <JT-Hardinge> Feed Over Ride Knob
[21:23:18] <MattyMatt> same to you :)
[21:23:20] <Jymmm> Oh, well then FORK YOU!
[21:23:29] <Jymmm> and the mill you rode in on!
[21:24:01] <MattyMatt> case 'G0':
[21:24:11] <JT-Hardinge> my deceased BIL license plate was QQQQ UNC
[21:24:17] <JT-Hardinge> I don't think he liked them
[21:27:52] <grommit> What would be the best tool to use to mill a curved slot in the wall of a part (for inserting a grommet into)?
[21:31:26] <archivist> ph-horn make tooling for that sort of job
[21:39:26] <frallzor> aha mhm it seems I can get vcarve and be happy
[21:55:11] <JT-Hardinge> does that mean I don't have to send you $2,000 to make you happy now?
[22:00:20] <grommit> I see a lot of tools at ph-horn, which one specifically?
[22:03:39] <archivist> only you know your machine and grommet
[22:04:47] <MattyMatt> frallzor, I should try a pic like that with this blender script. the original one was made for raster scanning pics
[22:05:12] <MattyMatt> it'll have to be elephants. that's all I've modelled
[22:06:05] <MattyMatt> I haven't posed a herd of them yet tho
[22:08:28] <grommit> I see now, I would have to mill from the side. Ok. Thanks,
[22:08:44] <MattyMatt> raster scanning can't be the best way to carve pictures tho
[22:09:09] <andypugh> Z-modulated hikbert curve
[22:09:13] <andypugh> (Hilbert)
[22:09:49] <MattyMatt> I've got 55,60 and 90 deg engraving tools in the post from France
[22:10:06] <MattyMatt> I want to trace the troughs
[22:10:37] <MattyMatt> maybe just a bias towards troughs while raster scanning
[22:11:29] <MattyMatt> I won't get away from zigzags with 3mm tools tho
[22:12:07] <MattyMatt> a giant chamfer could do every fine detail
[22:13:34] <MattyMatt> yeah the hilbert scanning would be great for small patches, like faces
[22:14:13] <andypugh> Probably very slow with all those corners.
[22:15:38] <MattyMatt> presumably speed would be limited by the Z moving constantly
[22:15:51] <MattyMatt> in a high relief patch
[22:15:57] <frallzor> JT-Hardinge yes send me $2000!
[22:17:45] <MattyMatt> zbuffer is the next thing to fix on this script
[22:18:23] <MattyMatt> it makes its own array, when it could use a blender image which gives other benefits
[22:18:27] <frallzor> wonder what my father will think about this motive...
[22:18:39] <JT-Hardinge> frallzor: I'll e-mail it to you ok
[22:18:46] <frallzor> sure :P
[22:19:08] <MattyMatt> motive for buying vcarve?
[22:19:19] <frallzor> the motive I milled
[22:19:25] <frallzor> maybe scene is a better word =)
[22:19:40] <MattyMatt> ah motif
[22:19:47] <MattyMatt> la mot francais
[22:20:48] <MattyMatt> yeah more than 3 wilderbeest and it's a scene, not a motif
[22:21:26] <frallzor> crap, I still need Aspire, ergo, I need cash =(
[22:21:51] <frallzor> wonder if I can earn the sum with the machine somehow..
[22:22:17] <MattyMatt> have you spoken to any carpenters?
[22:22:34] <frallzor> not yet, but now when I have something to show I will
[22:22:39] <MattyMatt> making furniture is pretty easy if you maill all the pieces to size
[22:24:32] <tvc> Hey anyone know if it is possible to setup EMC for 3 axis, but one of those axis rotational? Ie: Y,X, & A?
[22:24:54] <frallzor> its in stepconf at least
[22:24:57] <JT-Hardinge> theres nothing like the view of thundering herds of wildebeest from a Torquay hotel bedroom window
[22:25:09] <MattyMatt> mass produce reprap parts. you can get about 10 sets on an 8x4 sheet
[22:25:15] <archivist> tvc I ran mine like that for a while
[22:25:20] <andypugh> tvc: Yes.
[22:25:22] <frallzor> reprap naaah
[22:25:28] <JT-Hardinge> tvc: yes
[22:25:32] <frallzor> would need a laster for sharp corners =/
[22:25:40] <MattyMatt> the last set on ebay went for 310gbp
[22:25:45] <tvc> ok thanks guys, just gotta RTFM now...
[22:26:05] <frallzor> *laser
[22:26:07] <MattyMatt> I reckon 3 sets per week with my mill
[22:26:33] <MattyMatt> and I guess plywood will sell for less than plastic
[22:26:40] <JT-Hardinge> tvc: it is a good one I think :)
[22:26:52] <MattyMatt> so maybe I should be milling plastic :)
[22:26:56] <frallzor> MattyMatt how to solve corners then?
[22:27:23] <MattyMatt> corners?
[22:27:45] <MattyMatt> I can mill outside corners nice and square
[22:27:45] <frallzor> the parts surely have sharp inside corners and such?
[22:27:49] <JT-Hardinge> frallzor: lock the spindle and put a square punch in there like a broach
[22:28:16] <MattyMatt> a 4th axis would be handy for a few parts yes
[22:28:27] <pfred1> would it?
[22:28:38] <MattyMatt> but most of it can be done on 2 sides in a router
[22:28:50] <pfred1> how about an antique european wooden horn handled plane?
[22:28:58] <pfred1> think that'd be handy?
[22:29:04] <MattyMatt> could be
[22:29:16] <pfred1> thats what I thought when I picked one up earlier today
[22:29:21] <tvc> JT-Harding: initially I thought I could use the XYZA and leave X out, but it failed to load axis... I'm back to square one atm
[22:29:26] <MattyMatt> a tilting drill vice would be more so
[22:29:35] <pfred1> I got one of those
[22:29:43] <pfred1> came with my mill
[22:29:58] <pfred1> not a nice one with the protractor though one of the junky arm ones
[22:30:43] <pfred1> you know we throw you a defective vise with every mill puschase kind?
[22:31:12] <MattyMatt> I got my first scars on mine yesterday
[22:31:18] <andypugh> tvc: What error message? And did you leave X out of the HAL, or only the INI?
[22:31:24] <pfred1> I pretty much leave my 6" clone vise on the table now
[22:31:55] <MattyMatt> tried to cut 4mm deep through the jaw with a 3mm cutter. not pretty
[22:32:10] <MattyMatt> at woodcutting speed
[22:32:30] <pfred1> you have to be careful with a lot of vises I've noticed when you tighten them they lift the movable jaw end a few thousandths
[22:32:36] <MattyMatt> it got a fair way through tho :) I'll try milling more metal
[22:33:04] <pfred1> you can sort of fix it by using a bar of round stock on the movable end
[22:33:12] <pfred1> or just get a decent vise
[22:33:34] <MattyMatt> mine could be zinc. it's a toy one. the movable end is loose
[22:33:39] <pfred1> I noticed it when i was squaring up some stock
[22:33:50] <pfred1> yeah if its loose at all its lifting
[22:34:23] <pfred1> even smacking the work with a hammer the machine vibration will pick it back up
[22:34:31] <MattyMatt> I could mill the paint off, that would improve it. it's diecast
[22:34:32] <pfred1> drove me nuts!
[22:35:03] <pfred1> but if you put a piece of round stock about the height of the jaw on the movable end and tighten it that makes the work suck down to the fixed jaw
[22:35:23] <pfred1> it does work but you lose the capacity of the diameter of the round you use
[22:35:31] <MattyMatt> I saw an old article that did similar with square stock
[22:35:46] <pfred1> nah the round makes the work roll down to the fixed jaw its pretty neat how it works
[22:35:53] <pfred1> sort of cam locks it in
[22:36:04] <pfred1> don't look like it'd work but it does
[22:36:33] <pfred1> the movable jaw rides up but doesn't take the work with it I guess
[22:37:13] <pfred1> I got a couple of them "drill vises" and they all do it
[22:37:56] <MattyMatt> vices need electrifying these days
[22:37:58] <pfred1> the movable jaw only has about an inch or so of purchase slide going for them its not enough
[22:38:09] <pfred1> nah if you're cool you have a hydraulic one
[22:38:10] <MattyMatt> that's half the job, loading and unloading them
[22:38:24] <pfred1> we had hydraulic vises in the shop I worked in
[22:38:32] <pfred1> just do a foot switch lock unlock
[22:38:36] <MattyMatt> that'd do nice
[22:38:40] <pfred1> oh yeah
[22:38:46] <MattyMatt> do they show up in Axis?
[22:38:51] <pfred1> when you're doing 10,000 pieces it comes in handy
[22:39:30] <MattyMatt> oh a robot arm to do the loading too
[22:39:40] <MattyMatt> direct of your flatbed truck
[22:39:45] <pfred1> we'd blow out one of the chinese hyradulic units every week then the boss got us a real pump
[22:40:04] <MattyMatt> get a 6m wagon and keep all your stock in it
[22:40:15] <pfred1> we had racks
[22:40:26] <pfred1> and an electric hoist and a roller table
[22:41:06] <pfred1> we could get the hoist right out onto the flatbed trucks
[22:41:14] <MattyMatt> neat
[22:41:20] <pfred1> well we had to
[22:41:38] <pfred1> we'd get steel by the flatbed load
[22:42:02] <MattyMatt> it's all cheaper in 6m lengths, I've noticed
[22:42:19] <pfred1> I think they were 20' long bar stock we'd get
[22:42:31] <MattyMatt> same thing
[22:42:38] <frallzor> 6m is standard lengths so =)
[22:42:44] <pfred1> yuppers I think we paid a quarter a pound even back then
[22:42:48] <frallzor> cost more to cut and sell smaller pieces =)
[22:43:05] <pfred1> oh no ours was sheared at the foundry
[22:43:13] <pfred1> we'd always have to cut off the sheared ends
[22:43:28] <MattyMatt> I'm trying to think if I can handle 6m of 8mm shaft and get it cut before bending it
[22:43:36] <pfred1> lose like a half an inch on either side
[22:45:19] <pfred1> we used mainly bar stocks
[22:45:32] <pfred1> I'd go through tons of 3x4
[22:45:48] <pfred1> cut them up 5 at a time
[22:46:01] <pfred1> clamp them all on the roller table together and have at it
[22:46:57] <pfred1> thats the only thing I nicked when i was working ther was a clamp
[22:47:08] <pfred1> I should have taken 2 in every size
[22:47:19] <JT-Hardinge> * JT-Hardinge is glad to be on the easy row of the wiring of the fork
[22:47:27] <pfred1> but I was able to buy a pair at a garage sale once
[22:48:00] <pfred1> I'm almost done wiring up my last motor driver over here
[22:48:16] <MattyMatt> I've got 3 nice clamps for my bed. needs the 4th
[22:48:17] <JT-Hardinge> cool
[22:48:19] <pfred1> but I went out shopping today
[22:50:56] <pfred1> I should take a pic of them they're ingenious how they work
[22:51:10] <pfred1> Henry was a genius
[22:52:00] <andypugh> I have given up in disgust with my motor driver, the drive IC is ignoring me.
[22:52:20] <pfred1> andypugh the last one I built it was whacky what made it mess up
[22:52:34] <pfred1> andypugh chip has 2 grounds motor and logic
[22:52:48] <pfred1> andypugh I hooked the logic after the motor and it ran even with no pulses
[22:53:07] <pfred1> andypugh moved the connection like an 1/8th of an inch and it fixed it!
[22:53:21] <pfred1> andypugh too bad it took me 2 days to figure it out!
[22:53:47] <andypugh> I am pretty sure that my chip needs all the grounds wiring together
[22:53:51] <pfred1> I ripped just about the whole board up changed everything
[22:53:58] <pfred1> star is common
[22:54:03] <KimK> andypugh: which driver IC are you using, is this for your three-phase PWM project?
[22:54:07] <pfred1> but this star wastes it!
[22:54:15] <andypugh> IRAMS10UP06A
[22:54:25] <pfred1> I pulled the logic ground right off a filter cap and that did the trick
[22:54:54] <pfred1> before i sort of had it daisey chained with the motor grounds
[22:55:11] <pfred1> but the difference in wiring is so subtle its amazing the difference
[22:55:32] <pfred1> when it worked I was stunned that was what it was and it was as messed up as it was
[22:56:04] <andypugh> I am wondering if my lack of filter caps is the problem, but the logic 5V and 15V are from a bench PSU, should be filtered internally? Besides they look perfectly clean on the scope.
[22:56:20] <pfred1> when there's inductive load I try to jail the noise with filters
[22:56:48] <pfred1> my noise was low amplitude and high frequency
[22:56:56] <pfred1> like i had to turn my scope way up to see it
[22:56:59] <andypugh> There's no inductive load when it isn't even trying to drive either bridge.
[22:57:03] <pfred1> and all my drivers have it
[22:57:25] <pfred1> which was what was driving me nuts because drivers that work are noisy too
[22:57:51] <pfred1> but on the one I ran the ground what seemed easier to me
[22:58:13] <pfred1> not thinking it'd do what it did
[22:58:42] <KimK> IRF.com irams10up60a.pdf is that the one?
[22:58:56] <andypugh> Yes, that's the beast
[22:59:02] <pfred1> andypugh this is what helped me while I worked on it I kept telling myself that signal conditioning is most of electronics
[22:59:26] <pfred1> donno if it'll help you but I found solice in the thought
[22:59:55] <andypugh> I have _lovely_ signals now, out of the optos is the squarest, cleanest, up-to-the-rails and down-to-ground square wave you could ask for.
[22:59:59] <pfred1> I was just about to give up and build a whole new driver and I figured let me try one more thing
[23:00:08] <pfred1> yup thats what i had
[23:00:31] <KimK> so it's working now?
[23:00:38] <pfred1> mine is
[23:00:54] <pfred1> and i know how tou route the ground now too!
[23:01:03] <pfred1> or at least how not to
[23:01:51] <pfred1> I thought it was the inverter I was running it through that was sensitive to noise pulled that off the board
[23:02:03] <pfred1> changed caps changed the one ground resistor
[23:02:35] <pfred1> pulled the vregulator off checked it out
[23:03:17] <pfred1> 2 days screwing around with it
[23:06:03] <pfred1> hey here's the clamps i used to make: http://www.jstool.com/WRKHLDG.htm
[23:06:43] <pfred1> they don't show exactly how they work but there is a pocket in the nose the set screw rides in and the threads are only in the body
[23:07:12] <pfred1> so you turn the set and the nose goes up or down in the dovetail
[23:07:21] <pfred1> and pushes in or back
[23:07:52] <andypugh> Just like a TaperLok bush?
[23:07:56] <pfred1> and I've done every damned operation for making the things
[23:08:17] <pfred1> donno i know this is henry's invention he patented it
[23:08:29] <pfred1> like 60 or more years ago
[23:08:37] <andypugh> Talking of patents, I don't get this...
[23:09:07] <andypugh> http://www.gizmag.com/steve-durnin-ddrive-d-drive-infinitely-variable-transmission-geared/15088/
[23:09:46] <pfred1> heh if only people could understand the thing thats what we said about henry's other invention the wheel dresser
[23:10:20] <pfred1> it well you could understand the basics of it but what it could do appeared infinite in a way it was strange
[23:11:16] <pfred1> 'you ever rip apart a real manual transmission?
[23:11:48] <pfred1> I blew out the layshaft on one and tried to rebuild it and i almost got it too
[23:12:00] <pfred1> guy at the trans shop said i missed it by one spacer when I asked him
[23:13:12] <pfred1> he's full of junk once you're in gear regular transes are direct drive
[23:24:19] <andypugh> I also think that all his output torque comes from the "speed control" motor
[23:30:17] <andypugh> When a circuit diagram says "10m" next to a cap, does that mean 10,000uF?
[23:33:31] <KimK> If you're looking at page 9 of that pdf, I'd say no, since they use a 0.1 "m" there too, so I vote for (in this case) m= microfarads
[23:34:55] <pfred1> yeah they didn't have the funny font you need to make the uF
[23:35:09] <pfred1> the u is really an M isn't it?
[23:35:57] <pfred1> the blade in this plane is pretty old I wonder if its original to it?
[23:36:13] <KimK> It's fairly common practice to put an electrolytic (their 10m) in parallel with a ceramic or similar (their 0.1m) to get good noise supression at both low and high frequencies, respectively
[23:36:37] <pfred1> yeah that's uF
[23:37:45] <andypugh> I was just wondering why they used the SI prefix for "milli" when "u" for micro is less ambiguous, even if not actually correct.
[23:38:26] <andypugh> OK, I am going to add those caps, but I don't expect much difference.
[23:38:29] <KimK> ah, OK. pfred1 might be right, font issues?
[23:38:59] <pfred1> anybody here read german?
[23:39:47] <pfred1> this is exactly what I just got : http://www.holzwerken.de/museum/hersteller/kirschen_warenzeichen_1.jpg
[23:39:53] <andypugh> I assume that the rest of that stuff on page 9 is only relevant if you are using temp/fault sensing. (I already have the 6k8 resistor)
[23:40:33] <andypugh> That is _very_ german, isn't it?
[23:40:40] <pfred1> now what are these nazis going on about?
[23:41:31] <pfred1> even if it was made in 1900 still makes it an antique today I guess
[23:41:48] <pfred1> I saw the 1858 and was like dang this is old!
[23:42:53] <pfred1> though I do have some older planes
[23:44:35] <pfred1> I paid heavy for it though $15
[23:45:32] <KimK> andypugh: Yes, although that page 9 stuff includes a clever combination of over-current and over-temp switching. What did you choose for the bootstrap capacitors?
[23:46:11] <pfred1> yeah andy don't give up just keep at it man its good fir the brain
[23:46:35] <pfred1> like i said I was just about to give up over here when I got it
[23:46:59] <pfred1> it was literally the last thing I was going to try
[23:50:12] <pfred1> ah ha 1858 is when the company founded
[23:50:34] <pfred1> so this is a two cherries blade
[23:51:45] <pfred1> pretty cool I usually love this old kraut steel
[23:52:42] <pfred1> 110 years old still looks good
[23:54:39] <pfred1> I'll have a good time honing this puppy up
[23:59:54] <andypugh> I have experimented some more, and might try a different PWM scheme.
