[02:23:48] <skunkworks_> Tom_itx: there is a componant that would allow you to make a 4 input and gate.
[02:24:02] <skunkworks_> I guess you would need 3
[02:24:07] <skunkworks_> 3 input
[02:25:43] <Tom_itx> i don't think that would help any
[02:25:50] <Tom_itx> there are 2 separate outputs
[02:26:30] <Tom_itx> the reason for and2 and and6 is because edge pulses when you start lcnc
[02:26:37] <Tom_itx> and causes a fault
[02:27:19] <Tom_itx> otherwise it wouldn't be needed
[02:28:10] <Tom_itx> there shouldn't be a pulse because i've checked the outputs of the first 2 and gates

[02:31:15] -!- PetefromTn has quit [Remote host closed the connection]
[02:32:01] <Tom_itx> i'm not a good programmer but i don't think edge should pulse then

[02:48:07] <Jymmm> My print server jsut kicked my ass big time after I updated the firmware, it change the paraport to FIFO instead of Bi-Directional.

[17:33:37] <CaptHindsight> IchGuckLive: yes, they are, you can sail from the Atlantic all the way to Chicago
[17:34:22] <JT-Shop> yes it does but you only use 16-17 or 18-19 for the other one

[18:02:52] * JT-Shop goes to take a nap
[18:03:44] <CHNCguy> hey does anyone know if a regular quadrature encoder can be used as a spindle feedback encoder?
[18:04:42] <eric_unterhausen> why not?
[18:04:45] <archivist> I would say yes
[18:05:02] <eric_unterhausen> depends on the speed of the spindle and the max rate at which the counter can count transitions
[18:05:13] <eric_unterhausen> otherwise it's only a mounting problem
[18:06:07] <archivist> lathe/mill? and if threading one needs an index pulse
[18:06:08] <CHNCguy> well i its a 1000ppr encoder and the speed is up to 6k
[18:06:19] <CHNCguy> lathe
[18:06:30] <eric_unterhausen> what electronics?
[18:06:55] <JT-Shop> CHNCguy, I use the original encoder on my CHNC

[18:11:29] <zeeshan> lots of people on the forums like them.
[18:11:31] <eric_unterhausen> mesas can handle millions of transitions/sec so should be good at 1000 count encoder at 6000 rpm
[18:11:52] <CHNCguy> sorry im back. the encoder is stock, but on my 2nd one i dont have the encoder but i have a ballscrew encoder it fits fine too ;)

[18:30:34] <zeeshan> IchGuckLive: i am currently working on a lathe to start off with
[18:30:40] <zeeshan> then next will be my plasma table
[18:30:43] <zeeshan> and then the mill
[18:31:02] <zeeshan> using the lathe as a learning experience :P
[18:31:22] <zeeshan> the 570oz in steppers are for the plasma.
[18:31:22] <IchGuckLive> lathe i woudt go for a 21000 version so 8Nm or 680Oz
[18:31:30] <zeeshan> i already bought 1200oz in steppers for the lathe
[18:31:39] <zeeshan> from automationtechnologies
[18:31:45] <IchGuckLive> ok thats fine
[18:31:53] <IchGuckLive> now go up to 75V
[18:31:55] <zeeshan> i wanted to oversize just so i don't lose stepps
[18:32:03] <zeeshan> im using 2 72V switched supplies
[18:32:04] <IchGuckLive> and you are at the front end
[18:32:23] <IchGuckLive> 1 shoudt be ok
[18:32:30] <zeeshan> you thinkso?
[18:32:35] <zeeshan> each motor draws 7A
[18:33:10] <zeeshan> the power supplies are rated to 8A
[18:33:12] <IchGuckLive> this stepper does not need the full amP
[18:33:23] <IchGuckLive> you can hang up 2 of them
[18:33:46] <zeeshan> if im running both axis at full torque
[18:33:48] <IchGuckLive> zeeshan: that is the learn effect
[18:33:54] <zeeshan> then they'll draw 7A each?
[18:33:59] <IchGuckLive> no
[18:34:10] <zeeshan> please explain!
[18:34:35] <IchGuckLive> the phase that is driving takes 3.5*0.7Amp
[18:34:51] <IchGuckLive> you necer got all phase on power
[18:35:05] <IchGuckLive> so it can handle 2 motors
[18:35:07] <zeeshan> OHH
[18:35:15] <IchGuckLive> at may 25feet cable
[18:35:20] <IchGuckLive> max
[18:35:27] <zeeshan> so at any given pulse, 1 phase per motor is powered
[18:35:38] <IchGuckLive> yes
[18:35:58] <zeeshan> why the 0.7 factor?
[18:36:14] -!- WalterN has quit [Read error: Operation timed out]
[18:36:21] <zeeshan> even without the .7 factor
[18:36:23] <zeeshan> 3.5*2
[18:36:27] <zeeshan> 1 power supply can easily handle 2 motors
[18:36:34] <IchGuckLive> the phase divider for the Linduction
[18:36:37] <zeeshan> okay ill just use the other power supply for the miling machine.
[18:37:05] <IchGuckLive> for the toolchanfger turret use 48V
[18:37:13] <IchGuckLive> and small driver
[18:37:23] <zeeshan> i'm not using a turrent!
[18:37:28] <zeeshan> i'tll be a very basic cnc lathe
[18:37:34] <zeeshan> it'll have tachometer for index pulse
[18:37:37] <zeeshan> and 2 axis control
[18:37:51] <zeeshan> im using a quick change tool post to manually change tools
[18:37:52] <IchGuckLive> ok up to you
[18:38:36] <zeeshan> IchGuckLive: you've done some conversions?
[18:39:04] <IchGuckLive> on mashines no i build from block
[18:39:14] <zeeshan> oh wow
[18:39:16] <zeeshan> that's cool

[19:58:58] <CaptHindsight> the arm soc is only $6 from allwinner with 2 cores at 1Ghz

[20:00:52] <tjtr33> isnt andypugh working with the udoo?

[20:04:55] <tjtr33> whats your thoughts on seperating cnc control computer from gui user front end computer?
[20:06:04] <CaptHindsight> it works fine for those applications
[20:06:33] <CaptHindsight> I guess it comes down to why you want to do that or what you're trying to do
[20:06:57] <CaptHindsight> why use an ARM board instead of a x86 board?
[20:07:11] <eric_unterhausen> I like splitting the two functions
[20:08:25] <CaptHindsight> for a lowest cost appliance controller board that would run Linuxcnc then ARM + FPGA
[20:08:49] <tjtr33> i know that splitting is a revered programming concept ( basis of tcl/tk ) but if & where to cut the baby in half is best considered by those in the know of new hardware ( so, i ask )

[20:21:47] <tom_R2E3> hello
[20:22:13] <tom_R2E3> i'm struggling to wire up a MPG2 to mesa 7i77
[20:23:06] <tom_R2E3> i've changed the mode of 7i77 to mode 3, connected the encoder to pins 16&17, then connected ground and 5v
[20:23:43] <tom_R2E3> if I run linuxcnc then show hal config I was watch the 7i77 pin with the encoder connected and it counts!
[20:24:30] <tom_R2E3> however, i've connected the other buttons - Enable, select axis and select scale - but when I watch these pins in hal config then dont change
[20:24:37] <tom_R2E3> they*
