[00:03:10] <andypugh> PCW: The flasher is saying "No hm2 devices found" after successfully downloading the svua8_8 firmware to the 5i23. The 8i20 is in port 0 of the 7i44 which is on CN4. That ought to work, shouldn't it?
[00:04:02] <Tom_itx> i've got one that will do operations on data. i suppose that would work

[00:35:47] <andypugh> Crikey, this is a serious micrometer:
http://www.ebay.co.uk/itm/190744612617
[00:37:39] <PCW> Yes that should work (and I am assumung that firmware worked before)
[00:37:44] -!- L84Supper has quit [Ping timeout: 260 seconds]
[00:38:19] <andypugh> Yes, all I have done it shange the 8i20.BIN file.
[00:38:27] <PCW> no hm2 hardware found is pretty serious, means no 55AACAFE cookie at offset 0x100 in the FPGA
[00:38:57] <PCW> hardware issues?
[00:39:32] <andypugh> It reports success downloading the firmware to the card. (even reporting /DONE success)
[00:39:57] <PCW> what does dmesg say?
[00:40:08] <andypugh> dmesg in DOS?
[00:40:48] <PCW> Oh DOS
[00:43:07] -!- adb has quit [Ping timeout: 260 seconds]
[00:43:14] <PCW> Its probably one of those Motherboards where the DOS memory access fails
[00:44:06] <andypugh> It might be. It's an Atom board.
[00:44:19] <PCW> Intel Atom MBs are one that does not work
[00:44:35] <andypugh> So I do need to write the Linux version then?
[00:45:38] <PCW> so the loading and reading /done are done in I/O space (which always works) but HM2 access is always via memory (since its a 64K window = too big for I/O)
[00:46:17] <PCW> well I think you had another MB that worked at one time
[00:46:44] <andypugh> Yes. I probably plugged everything into ye olde xeon
[00:47:15] <PCW> some work some dont, seems BIOS dependent
[00:47:17] <andypugh> It's a bit more of a pain now, but I can try it.
[00:49:06] <PCW> programming is not terribly hard and AFAIK all cards are programmed the same (skip boot block, program next n blocks (however big the file is))
[00:52:12] <andypugh> I might be able to figure it out with the sourcecode.

[00:55:08] <PCW> The bad thing is if you make a mistake you may brick the device
[00:55:10] <PCW> So if you are writing code, probably best to let us test it first
[00:56:14] <andypugh> How common is it for the DOS utility not to work?
[00:58:51] <PCW> about 50% of newer MBs dont work
[00:59:13] <andypugh> And about 2% of users need to update their firmware?
[01:02:15] <PCW> Yeah

[01:09:15] <PCW> the windows utils always work (and are not a problem with the 8I20) but getting serial port access to 7I76 and 7I77 is awkward
[01:16:36] <PCW> If you are considering a Linux utility I would use SSERIAL and not the UART
[01:18:00] <PCW> (so the standard FPGA firmware can be used which avoids a couple awkward steps with 5I25 and 6I25 cards)

[08:14:17] <toastydeath> why does everyone machine at like half the speed of beard growth
[08:14:29] <toastydeath> every time there's a video someone posts, it's crawling along
[08:15:15] <Theta9> personally, it is hard to trust fast/light cuts will cut faster than slow heavy cuts
[08:15:35] <Theta9> i'm sure there is a level where fast/light will remove more material
[08:15:44] <Theta9> getting there is hard though
[08:15:56] <toastydeath> fast/light is beyond the ability of many hobby controls
[08:16:12] <toastydeath> and is still faster than most of the videos I see posted
[08:16:25] <toastydeath> slow and heavy isn't the issue, i'd understand that
[08:16:35] <toastydeath> what I don't get is these itty bitty cuts crawling along at 2 ipm
[08:17:11] <Theta9> well, even parallel port drivers can do better than that
[08:17:22] <Theta9> so, i doubt it is a driver issue
[08:17:48] <toastydeath> no, it's a control issue - the actual control itself
[08:18:31] <mrsun> why not medium/medium then? :P
[08:18:34] <toastydeath> get a machine moving 60-80 inches a minute and a lot of inexpensive or free controls can't handle changing directions
[08:21:08] <toastydeath> and i used to run a machine from the late 60s that could easily cut faster than that

[15:49:00] <r00t4rd3d> this is why we have daylight savings time
[15:49:48] <Jymmm> awallin: 1) about 30m, 2) It does, you just have to enable it =)
[15:50:10] <jdh> we should always have DST
[15:50:13] <awallin> Jymmm: wow that long, ok thanks... I'll wait
[15:51:01] <r00t4rd3d> jdh why? so when you go bug collecting after work you can still see?
[15:51:04] <r00t4rd3d> thats why we have it now.
[15:53:09] <jdh> I would rather have daylight later than earlier.
[15:53:30] <jdh> for mon-fri, it could stay dark until noon and I'd never notice.
[15:53:41] <jdh> and after all, I am the most important consideration.
[15:54:00] <pcw_home> It is rather silly much better to just change working ours to suit
[15:54:32] <jdh> yeah, but getting others to match mine isn't going tohappen.
[15:55:48] <r00t4rd3d> reading the history of dst is comical.
[15:55:49] <pcw_home> I think if DST were abolished, businesses, schools etc that cared would just adjust hours as appropriate
[15:56:11] <r00t4rd3d> "An avid golfer, he also disliked cutting short his round at dusk."
[15:56:20] <jdh> school hours changing without corresponding business hours changing woudl be chaotic
[15:57:04] <pcw_home> looks like Kazakhstan abolished DST in 2005
[15:57:26] <jdh> K could be a role model for the world!
[15:57:27] <r00t4rd3d> Hawaii, Arizona dont do it.
[15:57:45] <L84Supper> school days start too early IMHO
[15:57:58] <jdh> we ship our contaminated trash/dirt/etc to kazakhstan.
[15:58:10] <r00t4rd3d> and millions of dollars.
[15:58:13] <L84Supper> what are kids doing waiting for buses or walking to school at 7:00 am?
[15:58:37] <jdh> my bus came at 6:20 in high school
[15:59:01] <r00t4rd3d> i got kicked off and had to walk.

[17:49:04] <ktchk> Hi any recomandation for auto touch high adjustment for plasma table?
[17:50:46] <sliptonic> skunkworks: I'm converting a bridgeport clone (supermax ycm-30) Still struggling to get the mesa 7i77 analog5 to output 0-10v for the vfd though.
[17:51:49] <skunkworks> is it doing anything at all?
[17:52:41] <sliptonic> I'm configuring through pncconf. If I set min-0 max=10, and max scaling to 6000, then the pin will be at about 0v with the spindle off. It jumps to 1.7 when I start the spindle and stays there regardless of set speed.
[17:52:42] <skunkworks> you can see I scaled the spindle pwm to -4000
[17:52:58] <sliptonic> If I set max scaling to 1, it jumps to 10v.
[17:53:32] <skunkworks> huh
[17:53:55] <skunkworks> I have never used the pncconfg
[17:54:34] <skunkworks> so - when you do a m3s6000 with the above scaling - you get 1.7v?
[17:55:31] <sliptonic> So far, I've just been testing with the keyboard shortcuts, but yes.
[17:55:34] <tetbert> emc2 is running our y-axis, but not z or x
[17:55:44] <skunkworks> and spindle overrride is set to 100%?
[17:55:52] <sliptonic> Correct.

[18:54:53] <sliptonic> from .ini axis scale is 6000, max 10, min 0.
[18:55:08] <sliptonic> With spindle off, analog5 shows 64.6 mV.
[18:55:49] <sliptonic> m3s3000: analog5 shows 77.1mV
[18:58:22] <sliptonic> If I set output scale to 1, I can make it jump from ~65mV to 10V.
[18:58:33] <sliptonic> But nothing in between
[19:00:30] <pcw_home> you would need minlimit 0 maxlimit 6000 scalemin =-6000 scalemax =6000
[19:02:12] <pcw_home> oops no scalemin just 6000 for scale max
[19:03:45] <pcw_home> setp hm2_5i25.0.7i77.0.1.analogout5-scalemax 6000

[19:06:47] <sliptonic> pcw_home: Thank you! That was the one combination I didn't try.
[19:07:24] <pcw_home> maybe pncconf needs a bugfix
[19:08:06] <IchGuckLive> sliptonic: did you improve the VDF to 400kHz
[19:08:27] <IchGuckLive> be carfull with speeds below 2500
[19:08:41] <IchGuckLive> it will head up alot
[19:10:02] <sliptonic> IchGuckLive: I've seen that documented everywhere but I don't understand it. This is a 3 phase induction motor rated for 60Hz.
[19:10:45] <sliptonic> If I set the base freq for 60 and the max and min around that I can overdrive the motor. If I set it to 400 the motor won't start.
[19:10:49] <IchGuckLive> we speking about hyanyang watercooled spindles or
[19:11:12] <sliptonic> Huanyang vfd. Not spindle.
[19:11:35] <pcw_home> Master has the sserial manual with some hints on what the maxlim/minlim/scalemax do
[19:11:36] <IchGuckLive> ah ok then im out do you drive a servo with this vfd
[19:11:36] <pcw_home> (though they are described per card, they are the same for all sserial numeric output types )
[19:12:29] <sliptonic> pcw_home: pncconf is setting the values right. I just assumed max limit was the limit that the pin was putting out. Just me being ignorant.
[19:13:26] <sliptonic> IchGuckLive: Nope. Just the spindle motor. This is a bridgeport clone conversion.
[19:14:31] <IchGuckLive> ok i thougt i got now 5 of this working VFD and at Foam mill im always at 7500

[22:30:25] <KimK> andypugh: I second your idea, but would use it both for spindle growth comp (which I understand Sam has already done) and to use one of your "beefy SSRs" for turning a spindle chiller on/off and alarming if it gets too hot. And maybe keeping a few hours of temp history?
[22:31:34] -!- racycle has quit [Quit: racycle]
[22:31:49] <KimK> The exact circumstances were murky, but we had a spindle failure here recently that may or may not be traceable to spindle chiller failure. The machine in question had no overtemp alarm, nor any temperature history. Not even the operator's senses, since the door was closed and it was running.
[22:32:19] <roh> hm. you got such an expensive piece of hardware and no monitoring on it?
[22:33:04] <roh> just curious... i would have expected that something like that is default on such equipment
[22:33:26] <KimK> That's the way they build them, cheaper, I suppose. But with LinuxCNC we can add whatever we can imagine, and that machine is a LinuxCNC candidate.
[22:33:42] <roh> sure.
[22:36:44] <KimK> It's a 10,000 RPM spindle with only the usual greased bearings (nothing fancy like air bearings, or oil mist, or anything like that), so loss of the chiller above 5 or 6 K or so could lead to some heat. Exactly how much is a little uncertain.
