[11:31:12] <R2E4> I was reading in the forums, you can connect n MPG directly to the encoder input on the 7i77. Is there some truth to this?
[11:32:26] -!- dhoovie has quit [Read error: Connection reset by peer]
[11:33:38] <jthornton> aye, that is the way to connect your MPG to the 7i77
[11:35:39] <jthornton> I also have two selector switches, one for axis selection and one for increment
[11:36:19] <R2E4> They wire into inputs?
[11:36:38] <jthornton> they who?
[11:36:44] <R2E4> I have a parralel interface for it. iT is a cnc4pc
[11:37:00] <R2E4> asix selection and selector switches
[11:37:22] <jthornton> yes the selector switches are just inputs
[11:37:42] <R2E4> I think I will need more outputs and maybe inputs.
[11:38:10] <jthornton> http://linuxcnc.org/docs/html/examples/mpg.html
[11:38:47] <jthornton> IIRC you can get an I/O card for the second port on the 5i25
[11:39:01] <jthornton> as well as other options for even more I/o
[11:39:13] <R2E4> Thats what I am looking at on the mesa site
[11:39:28] <jthornton> one of the early things I do is make an I/O list to get a count
[11:40:04] <R2E4> I am working on an overview of the project.......
[11:40:10] <jthornton> PCW, knows all the options
[11:40:40] <R2E4> Phasing the project and filling in some details when I get them....
[11:41:03] <jthornton> you already have the 5i25 right?
[11:41:26] <R2E4> yeah, I have the 5i25 and 7i77 cables and mpg stuff.
[11:41:57] <jthornton> I think there is a sticker on the 5i25 that shows what it is programmed for
[11:42:42] <jthornton> IIRC a different bit file can be used for different card combinations
[11:43:01] <R2E4> I'll check it but I ordered it with the 7i77, so I would think it would come with the right configuration.
[11:43:59] <jthornton> I would guess it has 2 7i77's one for each port, if you need to use something else on port 2 you have to update the 5i25
[11:44:12] <R2E4> ok, I see.
[11:44:45] <R2E4> This is getting exciting. but damn.... theres alot to think of.
[11:45:12] -!- sumpfralle has quit [Ping timeout: 256 seconds]
[11:45:44] <jthornton> LOL yea it can get busy... just do one thing at a time
[11:47:06] <R2E4> I downloaded the software to update the 5i25, when I printed the manual yesterday.
[11:47:46] <R2E4> I printed the getting started, Integration and user guide linux CNC and the 5i25 and 7i77 manuals.
[11:47:56] <R2E4> nothing like having printed copies......
[11:48:21] <jthornton> easier to read, harder to search, easier to make notes in
[11:50:15] <R2E4> Think I am going to get a bucnh of relays mount them on DIN rails and drive them with the outputs from the mesa cards.
[11:50:54] <R2E4> or get some relay cards, dont know the requirements yet of the current and voltage of the switching.
[11:51:41] <R2E4> All the motors are 220 3 phase. You dont switch the three legs when powering 3 phase motors?
[11:53:48] -!- asdfasd [asdfasd!grgrgrgrg@] has joined #linuxcnc
[11:54:22] -!- micges has quit [Quit: Wychodzi]
[11:58:19] <jthornton> 3-phase motors use a 3-4 pole contactor rated for the amps that it draws
[11:58:28] <jthornton> don't you have all that in the machine now?
[11:59:13] <R2E4> plc relay would enable the contactor then?
[11:59:44] <R2E4> yes, it is there.
[11:59:57] <jthornton> normally the machine will have 24vdc coils on the contactors and you just wire that to the 7i77 outputs
[12:00:30] <R2E4> Theoretically I would just have to find which relay is used for which function and wire that into my relay on the outputs of the mesa board.
[12:00:40] <jthornton> aye
[12:00:56] -!- vladimirek [vladimirek!~vladimire@] has joined #linuxcnc
[12:01:17] <R2E4> ok....the contactor is tripped by the 24 volts....
[12:01:34] <R2E4> Damn..... this is going to be fun.
[12:02:19] <jthornton> normally when someone says relay they are switching a logic circuit and a contactor is switching a power circuit
[12:04:36] <R2E4> yeah. I'm pretty good with relays and timers. I use to build door interlocks with relays and timers......
[12:05:30] <R2E4> There was one that had 8 doors, with all kinds of logic. they didnt want to spend for plc, so I did it with relays and timers. They could have bought 5 plcs with the money it cost them.
[12:05:34] <jthornton> have you used the Automation Direct Click PLC's yet?
[12:05:55] <Tom_itx> jthornton, i thought of something... make a 'pulley' and put an o-ring around it fitted to your encoder shaft the size of your collet tube then mount the encoder atop and let it 'float' inside the tube
[12:05:55] <R2E4> I have used dl05 and 06's
[12:05:59] <jthornton> aye, and 10 AB buttons will buy you a touch screen
[12:06:16] <Tom_itx> the o-ring would help dampen vibration as well
[12:06:39] <R2E4> yeah...... its amazing they get that much for those things.
[12:06:54] <jthornton> Tom_itx, I'm not following
[12:07:04] <R2E4> You can get the same stuff at surplus stores for less than 5 bucks
[12:07:35] <Tom_itx> wedge the pulley with the o-ring on it inside the tube as a friction contact mechanism to drive the encoder shaft
[12:09:34] <jthornton> I have a good coupler for the encoder so I'll use that to avoid any side load on the encoder shaft
[12:09:36] <Tom_itx> make the pulley similar to what i did on the wheels on this bot only smaller: http://tom-itx.dyndns.org:81/~webpage/largebot/largebot1.jpg
[12:10:05] <Tom_itx> with a groove around the edge to seat the o-ring
[12:11:05] <jthornton> I'm just making a shaft with some o-ring grooves to push down into the tube and a shoulder to sit on the top then a small stub shaft for the coupling
[12:12:03] <Tom_itx> if you look closely, i used a grommet here to mount an encoder to the large wheel: http://tom-itx.dyndns.org:81/~webpage/motors/focusring3.jpg
[12:12:18] <Tom_itx> rather than driving it by it's intended gear
[12:13:00] <Tom_itx> the encoder is on the back side out of view
[12:13:21] <jthornton> back of the driven pulley?
[12:13:26] <Tom_itx> yes
[12:13:34] <Tom_itx> the other is just a motor
[12:14:28] <Tom_itx> i made an angle mount to hold the encoder also not visible there
[12:14:56] <jdh> http://raleigh.craigslist.org/tls/3880109107.html
[12:15:01] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/motors/focusring1.jpg
[12:15:06] <Tom_itx> there's the back side of it
[12:16:44] <jthornton> yep, I'm making a similar bracket to mount to the jacking screw holes
[12:16:48] <Tom_itx> if i didn't need the collet tube i'd use one of those on my sherline
[12:16:53] <Tom_itx> since it has index
[12:17:11] <jthornton> you have a draw bar?
[12:17:19] <Tom_itx> yeah, of sorts
[12:17:23] <Tom_itx> it's just a long screw
[12:17:41] <Tom_itx> only used for morse 2 taper holders like my drill chuck etc
[12:17:52] <Tom_itx> the collets screw to it from the bottom
[12:18:36] <Tom_itx> ok gotta run or i'll be late

[16:35:40] <dosas> hi, for my driver i need an enable pin so i'm trying to set all 3 enable signals on one pin
[16:35:45] <dosas> but when i use
[16:35:50] <dosas> net xenable => parport.0.pin-07-out
[16:35:55] <dosas> net yenable => parport.0.pin-07-out
[16:35:58] <dosas> net zenable => parport.0.pin-07-out
[16:36:06] <dosas> it complains that the pin is set 3 times
[16:36:12] <Tom_itx> yes
[16:36:22] <dosas> how do i do this i read in the wiki that it is possible but they do not show how
[16:36:34] <Tom_itx> use the net
[16:37:07] <Tom_itx> err i'm not sure you can do that, maybe if you used an 'or' gate
[16:37:21] <dosas> okay
[16:37:25] <Tom_itx> xneable -> or -> to the port pin
[16:37:28] <Tom_itx> next or
[16:37:29] <Tom_itx> next or
[16:38:22] <dosas> okay i will try this thank you

[16:51:04] <willburrrr2003> Am I right to assume that "net spindle_enable motion.spindle-on => pwmgen.0.enable => pid.0.enable" is the same as entering "net spindle_enable motion.spindle-on => pwmgen.0.enable"and "net spindle_enable motion.spindle-on => pid.0.enable" ?
[16:51:07] <JT-Shop> that's what it takes to fill the hole so it is 1.030" od

[23:09:44] <jdh> money isn't everything, but I'd probably quit going to my job if they didn't pay me.
[23:10:00] <tjb1> Hard to pay rent without any ;)
[23:10:18] <tjb1> I had to load up a credit card pretty good to get up here and get started
[23:10:33] <jdh> that sucks
[23:10:58] <jdh> suck it up and pay it off as fast as possible even if you have to scrimp on things
[23:11:04] <jdh> like, food, etc.
[23:14:16] <Jymmm> tjb1: Top Ramen ; green onions, raw egg, sliced luncheon meat, carrots, celery, sliced pickled ginger, basil, bean sprouts, bok choy, cabbage, frozen veggies
[23:14:34] <tjb1> Jymmm: sounds expensive
[23:14:41] <tjb1> How about just ramen? :P
[23:14:58] <Jymmm> tjb1: not ALL of them, jsut whatever you have. frozen veggies are cheap
[23:15:09] <tjb1> I just eat lunch meat sandwiches
[23:15:13] <tjb1> eggos for breakfast
