#linuxcnc | Logs for 2013-11-12

[01:50:38] <RyanS> What is the deal with every time a recommendation for a VFD pops up, its TECO, TECO, TECO?
[03:13:46] <MacGalempsy_> three position switch. is it to run one powered all the time to show the switch is powered (one input) and the other activated at latch?
[03:14:16] <MacGalempsy_> oops three wire switch
[03:40:34] * archivist off to the advanced engineering show at the NEC
[04:04:38] <MacGalempsy_> nm problem solved
[04:31:50] <dougztr> setting up vim for .nc files ... good idea
[05:04:37] <_DJ_> moin
[05:20:10] <jthornton> morning
[05:22:35] <MacGalempsy> morning
[05:24:20] <MacGalempsy> any chance of direction with this error that came up when attempting to start linuxcnc? http://pastebin.com/8d839Xpk
[05:29:24] <jthornton> I can't spot anything, when you have a problem like this clear dmesg then run the config the capture the dmesg
[05:30:01] <jthornton> sudo dmesg -c
[05:30:06] <MacGalempsy> ok ;)
[05:30:08] <jthornton> http://linuxcnc.org/docs/html/common/Linux_FAQ.html#_bootup_messages
[05:30:10] <MacGalempsy> brb
[05:30:18] <jthornton> what did you do before the error?
[05:30:29] <MacGalempsy> nothing just ran pncconf
[05:30:47] <MacGalempsy> let me go out to the garage and clear this
[05:35:46] <jthornton> MacGalempsy, on the forum attach the file to your message instead of using pastebin. Use pastebin here...
[05:41:02] <MacGalempsy> ok.. just went out there, but realized its time to get started on 6am reports.
[05:41:47] <jthornton> ok
[05:41:57] <jthornton> did my sample configuration run?
[05:43:15] <MacGalempsy> no
[05:43:23] <MacGalempsy> not even the precompiled ones
[05:43:46] <jthornton> precompiled?
[05:44:24] <MacGalempsy> just what ever the basic configs that popup when linuxcnc starts. but perhaps becuase they are not for this card, they failed
[05:44:53] <MacGalempsy> i just wanted to get past the second screen
[05:44:56] <jthornton> right, there is no 5i25 config there. try and run my sample configuration
[05:45:18] <MacGalempsy> just put the 2 files in the configs folder?
[05:45:47] <jthornton> no, a config folder has to have a tool table and a var file as well as the hal and ini file
[05:46:51] <MacGalempsy> so how do I use just the two files?
[05:47:26] <jthornton> did you get the pin names by following the "Hal Pin Names" here http://gnipsel.com/linuxcnc/configs/index.html
[05:47:26] <MacGalempsy> yes
[05:47:54] <jthornton> give me a min
[05:48:30] <jthornton> I'm a ding bat, I should have put the rest of the files in there
[05:52:26] <jthornton> there should be 5 files when you unzip the sample config from http://freeby.mesanet.com/7i77.zip
[05:53:41] <MacGalempsy> sure was a slow night in the oil patch
[05:54:04] <MacGalempsy> only 1 out of 4 rigs drilling ahears
[05:54:07] <MacGalempsy> ahead
[05:54:28] <jthornton> land rigs or offshore?
[05:54:38] <MacGalempsy> land
[05:54:47] <MacGalempsy> still only 2 files that I can see there
[05:55:00] <MacGalempsy> 2 in ohio, 2 in oklahoma
[05:55:05] <jthornton> from that link http://freeby.mesanet.com/7i77.zip
[05:55:13] <MacGalempsy> usually its texas
[05:55:29] <jthornton> hmm
[05:55:36] <MacGalempsy> yep. when I click on that link, the zip opens and only 2 files
[05:56:04] <jthornton> give me a moment
[05:56:19] <MacGalempsy> ok. going to get a cup of water
[05:58:57] <MacGalempsy> it would be cool to make a mini rotory steerable unit to sell to engineers that have it all ;)
[06:03:50] <jthornton> http://gnipsel.com/linuxcnc/configs/7i77.html
[06:04:05] <jthornton> download my sample config
[06:05:28] <MacGalempsy> again the bp one had multi files, the sample only has 2
[06:06:34] <jthornton> refresh the page, there are 3 configs now
[06:06:43] <MacGalempsy> ah ok
[06:08:54] <MacGalempsy> cooll. going out to the garage. will log in on my laptop out there.
[06:11:45] <MacGalempsy> yay it worked
[06:13:05] <jthornton> woopee
[06:13:34] <MacGalempsy> im about to explode with excitement because its a whole new step in the right direction
[06:13:35] <jthornton> ok, you know you have working hardware, you can modify the sample config or continue with pncconf
[06:14:01] <MacGalempsy> so why would pncconf now work?
[06:14:41] <jthornton> you would have to ask on the forum about that
[06:14:54] <MacGalempsy> all I care is that it works.
[06:14:59] <jthornton> Chris Morley is pncconf
[06:15:27] <jthornton> I'm updating my page to have the files needed for the Mesa sample config to work... sorry about that
[06:16:06] <jthornton> if you go into the sample ini file and set the items for each axis you should be able to move it
[06:16:24] <jthornton> set scale and limits
[06:16:56] <MacGalempsy> there is a z-brake
[06:17:30] <MacGalempsy> will have to hit that relay, I guess, but first x&y
[06:17:45] <jthornton> that should be released when the drive is energized
[06:18:12] <MacGalempsy> the zbrake is on its own power relay
[06:18:37] <MacGalempsy> two wires come down, but I can hotwire them to let the machine go up and down
[06:18:38] <jthornton> yes, you can connect many outputs to a single signal in hal
[06:20:27] <jthornton> actually my config does need quite a bit of hal added
[06:20:49] <MacGalempsy> so what do you do for a 9-5?
[06:21:33] <jthornton> I design and build automation equipment, I have a CNC machine shop in my back yard lol
[06:22:32] <jthornton> I used to work offshore on jackup rigs (Gulf and West Africa), build destroyers, overhaul submarines, and make nails
[06:23:12] <MacGalempsy> very cool. ive been a petroleum geologist for about the last 7 years, working onshore
[06:23:47] <jthornton> cool, I bet the oil field has changed a bit since I worked there
[06:24:20] <MacGalempsy> I do everything from the home office, they send me drilling data, it gets modeled and then reported
[06:24:36] <jthornton> last rig I worked on we had a pipe spinner but it was broken most of the time so we threw the chain going in the hole
[06:24:41] <MacGalempsy> thus slow nights gives a lot of time to work on machines
[06:24:47] <jthornton> cool
[06:26:27] <MacGalempsy> my hopes are to use this machine to make a some injection molds for classic landcruiser parts
[06:26:43] <MacGalempsy> and work on some miniture drilling equipment
[06:27:05] <jthornton> cool
[06:29:03] <MacGalempsy_> ok
[06:29:49] <Tom_itx> 24f.. brrrr
[06:31:08] <jthornton> I'm adding some stuff to my 7i77 sample config
[06:31:17] <jthornton> 37f here Tom and snowing
[06:31:34] <Tom_itx> no white, just.... brrrrr
[06:31:59] <Tom_itx> no cloud cover to keep it in
[06:37:04] <jthornton> MacGalempsy, the first thing I do when testing an axis is to move the axis by hand and watch the DRO to be sure my feed back is connected correctly
[06:37:18] <jthornton> this is done before energizing the axis drive
[06:44:29] <MacGalempsy_> no dro readout
[06:45:05] <jthornton> I updated my sample config with the hal items needed for a basic configuration
[06:45:27] <jthornton> refresh the page and get the latest config
[06:46:34] <MacGalempsy_> i dont have the faults and resets hooked up, guess those are needed to enable the drive
[06:47:18] <jthornton> you don't need to enable the drive to test the encoder counts and direction
[06:47:54] <jthornton> my original config did not connect any thing up to the encoders but the latest one should
[06:48:11] <MacGalempsy> oh there is another one since you had me download it the last time?
[06:48:22] <MacGalempsy> ok. let me redownload
[06:48:48] <jthornton> yes, I just uploaded it
[06:49:12] <MacGalempsy> ok cool
[06:50:13] <MacGalempsy> but first I need to edit the pins so the estop is to the correct port
[06:51:04] <jthornton> yes, are you using an external e-stop?
[06:51:10] <MacGalempsy> yes
[06:51:58] <jthornton> let me get the bit of hal you need to connect up the external estop
[06:52:38] <MacGalempsy> the pin is hm2_5i25.0.7i77.0.0.input-00 is typically ground. when the estop is hit, the it shows 24v
[06:52:52] <jthornton> http://linuxcnc.org/index.php/english/forum/47-hal-examples/25861-external-e-stop
[06:54:21] <MacGalempsy> net remote-estop estop-latch.0.fault-in <= hm2_5i25.0.7i77.0.0.pin-in00
[06:54:35] <MacGalempsy> just replace that last line in the code?
[06:54:39] <jthornton> change parport.0.pin-in10-not to hm2_5i25.0.7i77.0.0.input-00 in the example I linked to
[06:54:41] <jthornton> yes
[06:55:05] <jthornton> and comment out the std estop loop
[06:55:45] <MacGalempsy> that is the loopout and loopin, correct?
[06:56:29] <MacGalempsy> cool
[06:56:34] <jthornton> yes
[06:57:33] <MacGalempsy> ok, so my axis have max and min endstops
[06:57:44] <MacGalempsy> axes....
[06:59:25] <jthornton> yes the min and max travels set the soft limits, after homing LinuxCNC will not allow the machine to exceed them
[07:00:17] <MacGalempsy> so the power is generally on, until the switch is hit
[07:01:17] <jthornton> after you clear the estop in LinuxCNC and then energize the power pressing the external estop should kill power and show estop on your config
[07:01:55] <jthornton> after pulling out the external estop you will need to press power (F2) again to restore power
[07:01:58] <MacGalempsy> so for now ignore the max limit switch?
[07:02:39] <jthornton> when your estop chain is working properly you can connect up the limit switches in hal
[07:03:48] <jthornton> axis.N.neg-lim-sw-in and axis.N.pos-lim-sw-in are the limit switch connections
[07:05:03] <jthornton> so something like net x-pos-limit axis.0.pos-lim-sw-in hm2_5i25.0.7i77.0.0.pin-in??
[07:05:20] <jthornton> with ?? being the pin number
[07:23:27] <Jymmm> Today is: 11/12/13
[07:23:47] <_DJ_> hmm, in germany it is 12.11.13
[07:24:08] <cpresser> Today is Sweetmorn, the 24th day of The Aftermath in the YOLD 3179
[07:30:41] <MacGalempsy> strange, the first file you put out there with all 5 files worked fine, this new one does not work at all
[07:31:19] <jthornton> what is the error?
[07:31:30] <MacGalempsy> the same as before, would not start
[07:31:35] <jthornton> I can't test it down here in the beer cave...
[07:31:40] <jthornton> dmesg
[07:32:10] <Jymmm> jthornton: It's not even noon yet ya lush!
[07:32:45] <jthornton> well I'm drinking blueberry juice... and surrounded by beer and wine
[07:33:00] <Jymmm> Blueberry Beer?
[07:33:14] <Jymmm> Blueberry Wine?
[07:33:27] <jthornton> I've made blueberry wine before
[07:33:52] <Jymmm> And now partaking the fruits of your labor
[07:34:35] <Jymmm> in liquid fermented form
[07:34:47] <jdh> it's a little early for that.
[07:35:14] <Jymmm> on your corn flakes
[07:35:24] <PetefromTn> Supposed to get BUTT cold her today apparently....also winds 20-30MPH....
[07:36:19] <PetefromTn> Makes me long for the warmth of South Florida LOL
[07:37:16] <jthornton> until July...
[07:37:32] <alaubhan> ok pastebin http://pastebin.com/JBbBL1Gh
[07:39:08] <MacGalempsy___> that is the dmesg after the error
[07:39:52] <jthornton> hmmm I don't see anything, does LinuxCNC also give an error screen?
[07:39:59] <MacGalempsy> none
[07:40:08] <jthornton> I'll have to test it in a bit when I go out to the shop
[07:40:32] <MacGalempsy> ok. again, I appreciate your help. time for me to hit the sack.
[07:41:09] <jthornton> ok, I updated my web page some more and I'll test the config on my machine to make sure it runs today and update that too
[08:33:36] <JT_Shop> MacGalempsy___, when you wake up I fixed the config and uploaded to my web site.
[08:48:52] <Tom_itx> MacGalempsy___, axis has a DRO by default
[08:52:20] <Tom_itx> Jymmm, you should have waited to tell us at 14:15:16
[08:57:30] <Tom_itx> JT_Shop, why do you use a latch on estop?
[08:57:47] <Tom_itx> i was just looking at mine on the pendant
[09:05:04] <Tom_itx> is it just for the soft estop 'circuit' ?
[09:05:21] <Tom_itx> so both can't be activated at once
[09:09:04] <jdh> dhoovie seems to have connection issues.
[09:39:56] <SadMan> what's the difference between latency-test and latency-test-atom?
[11:41:42] <IchGuckLive> hi all B)
[11:41:53] <jdh> <all> hi
[11:44:03] <IchGuckLive> at this time of the day linuxcnc is not very bussy as all are resting
[11:45:16] <WalterN> I'm getting ready to make a fancy program
[11:45:30] <IchGuckLive> python or gcode
[11:45:32] <Tom_itx> to do what?
[11:45:35] <kwallace2> Too busy working.
[11:45:39] <WalterN> Gcode
[11:45:50] <IchGuckLive> nice i make this most time
[11:45:55] <IchGuckLive> fancy is best
[11:46:02] <IchGuckLive> from image to gcode
[11:46:18] <Tom_itx> using what?
[11:46:33] <IchGuckLive> gimp incscape heeks
[11:47:03] <WalterN> its a die thing for thick electrical wires... there is a huge range of wire sizes, several hundred anyway. When the customer orders them they order maybe 50, but like 3-4 of each size
[11:47:09] <IchGuckLive> i do only need outlines
[11:47:37] <WalterN> getting ready to take a program for one size and make it a generic program to do a large range of sizes
[11:48:35] <IchGuckLive> WalterN: i woudt go for python as it is integreadet in linuxcnc you can d generate from that simple gcode
[11:48:35] <jdh> sounds well suited for a c/perl/python gcode generator
[11:48:40] <IchGuckLive> did you see our simple gcode examples on python
[11:48:48] <WalterN> IchGuckLive: that would be nice if the machine ran off of linuxCNC
[11:49:11] <WalterN> wait, what?
[11:49:15] <IchGuckLive> if it takes gcode why no
[11:50:16] <WalterN> also, I dont know python... mostly only C and java
[11:50:21] <IchGuckLive> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_LinuxCNC_G-Code_Generators#Grid_Rectangular_Circular_SpiderNet_G_code_Generator
[11:50:45] <IchGuckLive> this is from me
[11:51:05] <IchGuckLive> also the airfoilgenerator witch meets your needs most
[11:51:30] <IchGuckLive> WalterN: you can see the dropdowns witch generate gcode for your need on your choice
[11:51:50] <IchGuckLive> left drop down woudt be the size right the count
[12:24:54] <jdh> l
[12:26:16] <IchGuckLive> 2
[12:40:51] <Jymmm> Tom_itx: =)
[13:40:47] <IchGuckLive> im off BYE
[13:40:53] <archivist> grmbl, Renishaw didnt bring the rotary encoders to the show today
[14:11:02] <skunkworks> http://www.youtube.com/watch?v=egSSJ6_JwOA&noredirect=1
[15:35:14] <MacGalempsy> afternoon all
[16:15:01] <_DJ_> gn8
[16:30:14] <WalterN> what is the turning roughing command? G71?
[16:51:44] <WalterN> seems so
[17:05:35] <WalterN> herm
[17:15:15] <WalterN> does G71 skip the block of code once its done?
[17:15:44] <WalterN> I mean...
[17:15:48] <WalterN> [cut stuff]
[17:16:08] <WalterN> G71 P1 Q5 [stuff]
[17:16:44] <WalterN> meh, need pastebin
[17:17:31] <WalterN> but everything between N1 and N5 is not run twice, right? G71 returns operation of the program at the end of N5
[17:55:22] <JT_Shop> there is no G71
[17:56:40] <Tom_itx> wow, did somebody change the font on the webpage?
[17:57:38] <JT_Shop> looks the same to me
[17:58:16] <Tom_itx> on the gcode page for example, the numbers appear smaller than before i think
[17:59:24] <Tom_itx> maybe it was a recent brouser update...
[17:59:25] <Tom_itx> who knows
[18:01:09] <JT_Shop> might have hit a key on your keyboard that changes text size
[18:01:41] <Tom_itx> it's the only place i've noticed it
[18:03:01] <JT_Shop> it does look like a different font
[18:04:54] <Tom_itx> G71 is metric parameter on a Fadal
[18:05:10] <Tom_itx> G70 inch
[18:09:42] <WalterN> JT_Shop: what do you mean no G71?
[18:10:26] <WalterN> I was just reading about it in the fanuc operators manual
[18:12:59] <JT_Shop> oh then your on the wrong channel this is the LinuxCNC IRC channel
[18:15:40] <WalterN> I know not of another CNC machine channel
[18:16:48] <WalterN> or machining channel in gernal
[18:16:50] <WalterN> general
[18:17:02] <Tom_itx> there are some
[18:17:07] <Tom_itx> i forget which ones
[18:17:22] <mpictor> WalterN: talk to faunuc? read the manual?
[18:17:57] <JT_Shop> WalterN, your asking questions about Fanuc G code on the LinuxCNC channel...
[18:18:23] <JT_Shop> there are thousands of different variants of G code besides LinuxCNC
[18:18:30] <MacGalempsy> guys, after linuxcnc is running and I execute halrun in terminal, when saving, does that save as the active HAL in linuxcnc?
[18:18:34] <WalterN> and anodizing...
[18:18:55] <WalterN> and lasers/optics
[18:19:01] <JT_Shop> MacGalempsy, if I understand what your asking no
[18:19:27] <MacGalempsy> the ulitimate question is, can I edit the halfile while linuxcnc is running?
[18:19:37] <JT_Shop> WalterN, sure we talk about many things but when you ask about G code we assume you mean LinuxCNC
[18:19:59] <JT_Shop> MacGalempsy, you can but it won't take effect till you start again
[18:20:11] <JT_Shop> did you get the updated sample configuration files?
[18:20:50] <MacGalempsy> did you upload new ones? I just went back to the earlier ones that worked, and planned to try and go from there
[18:21:32] <WalterN> I just havent had a chance to change controllers at all... I will probably be converting a manual lathe into a CNC gang tooling type machine though sometime if the shop slows down :P
[18:21:46] <JT_Shop> yes, I had a mistake in the one you downloaded this morning and fixed and tested on my 5i25 7i77
[18:21:49] <WalterN> among other things
[18:22:10] <MacGalempsy> sweet. will d/l now and load it up. going to the garage
[18:36:11] <CaptHindsight> http://www.3ders.org/articles/20131112-diwire-the-first-ever-desktop-wire-bender-a-new-kind-of-3d-printer.html
[18:36:35] <MacGalempsy> still no sucess. it just goes straight to the error again...
[18:37:07] <CaptHindsight> http://vimeo.com/41425580 DIWire Bender
[18:38:12] <JT_Shop> run linuxcnc from the menu and pick that config and let me know what the error is
[18:38:38] <MacGalempsy> ok. I will get the dmesg an put it to pastebin
[18:39:17] <JT_Shop> linuxcnc might pop up a different error than dmesg if you run it that way
[18:42:03] <JT-Droid> Test
[18:42:38] <JT-Droid> Test
[18:42:44] <MacGarage> JT_shop - http://pastebin.com/AAvyTdQX
[18:43:42] <CaptHindsight> wow $3200+ for a CNC wire bender
[18:44:37] <JT-Droid> Run tge config from cnc linuxcnc
[18:44:58] <MacGalempsy> i tried, that is what came up
[18:45:41] <MacGalempsy> I select it from the list, and that is the dmesg that results, even after sudo dmesg -c
[18:45:53] <JT-Droid> Did you refresh your browser?
[18:45:59] <MacGalempsy> yep
[18:46:12] <JT-Droid> Im running that confignow
[18:46:49] <MacGalempsy> are there additional download requirements then just installing the linuxcnc disk?
[18:46:55] <JT-Droid> And i dl from my web page to the mill
[18:47:25] <JT-Droid> Are you sure your running the right config
[18:48:05] <MacGalempsy> this is how I do it. there is only one folder in the configs, it is the file you posted wiht updates around 8am this morning
[18:48:36] <MacGalempsy> when I open linuxcnc, there is a list, I select the one that goes with your file, and it wont start up
[18:48:55] <MacGalempsy> the one you posted without the axis section seems to work fine
[18:49:06] <JT-Droid> Installing the livecd then running one config from the config picker zets everythingup
[18:49:34] <JT_Shop> pardon the droid, I'm just getting use to it
[18:50:02] <MacGalempsy> so run the config that works, then try to switch too the config that doesnt after linuxcnc is running?
[18:50:04] <JT_Shop> this is the latest config http://gnipsel.com/linuxcnc/configs/files/5i25-7i77.zip
[18:50:34] <JT_Shop> I'm running it on my mill and it runs and you can move the axes and see the DRO change
[18:50:39] <MacGalempsy> that is the config im trying to tun
[18:51:03] <MacGalempsy> do all the pins and stuff need to be changed before attempting to run?
[18:51:25] <JT_Shop> no, it should run out of the box with a 5i25/7i77
[18:51:58] <JT_Shop> did you put it in it's own directory?
[18:52:02] <MacGalempsy> maybe I should remove the tb1 power supply and just run for the 5i25 pwr?
[18:52:08] <JT_Shop> it/latest config
[18:52:21] <MacGalempsy> yes,the folder contents are in their own folder
[18:52:43] <JT_Shop> the 7i77 needs field power or the config will not run
[18:52:50] <MacGalempsy> it has field power
[18:52:59] <MacGalempsy> and when I do show pins, they all come on
[18:53:20] <JT_Shop> you may still have linuxcnc running then
[18:53:33] <JT_Shop> did you do a halrun and leave it oopen?
[18:53:49] <MacGalempsy> do I need to have halrun open?
[18:54:05] <JT_Shop> no, you can only run one at a time and you can'
[18:54:17] <JT_Shop> t run a latency test at the same time either
[18:54:20] <MacGalempsy> I even rebooted then tried starting it
[18:56:01] <JT_Shop> when you run from Applications > CNC > LinuxCNC and pick that config to run you should get a LinuxCNC error screen if there is a problem
[18:56:29] <MacGalempsy> yes it comes up and the whole thing shuts down
[18:56:41] <JT_Shop> what is in that error screen?
[18:57:00] <JT_Shop> that is usually the best clue
[18:57:49] <MacGarage> there is a print file information header
[18:58:15] <MacGarage> but I cannot seem to copy the info
[18:58:53] <JT_Shop> if you select all the text and press the middle mouse button or wheel it will copy then press it again to paste to a file
[18:58:55] <MacGarage> can not find -sec MOT -var MOT -num 1
[18:59:13] <JT_Shop> having opened up a text file and middle click in it
[18:59:13] <MacGarage> cannot find -sec EMCMOT -car EMCMOT -num 1
[18:59:48] <JT_Shop> I think that is normal
[19:00:59] <Jymmm> Click in the text area, CTRL+A to select all, CTRL+C to copy, CTRL+V to paste.
[19:01:27] <JT_Shop> sometimes that doesn't work with some interfaces in linux :(
[19:01:35] <MacGarage> http://pastebin.com/az9NNMu4
[19:01:39] <Jymmm> then they're fucked up
[19:01:40] <JT_Shop> sometimes only the middle mouse works
[19:01:55] <MacGarage> one of those combos worked, not sure which one
[19:02:04] <JT_Shop> 7i77.hal:42: Pin 'hm2_5i25.0.7i77.0.1.analogena
[19:02:06] <Jymmm> Nobody has a middle button since the 80's
[19:02:24] <JT_Shop> the wheel works too as a middle button
[19:02:37] <Jymmm> What mouse wheel?
[19:03:07] <Jymmm> ever heard of trackpads, trackballs
[19:03:16] <JT_Shop> MacGalempsy, line 37 is the error
[19:03:41] <JT_Shop> for some reason the 7i77 pins are not showing up like field power or 5v is not correct
[19:03:52] <Tom_itx> Jymmm, the middle button is for your middle finger
[19:04:01] <MacGalempsy> maybe a connection came loose
[19:04:29] <JT_Shop> I'm heading in and will watch from the droid
[19:04:44] <Jymmm> Tom_itx: Nah, top-right button, which is programed to PASTE.
[19:04:50] <MacGalempsy> tb1 has a 5v psu from a cellphone charger. fieldpower is 24v from a 100w psu
[19:05:07] <MacGalempsy> and vin and field power are shared o nthe 7i77
[19:05:56] <MacGalempsy> will go back through the wiring
[19:06:09] <MacGalempsy> so that is why the ealier one with no axis settings worked ;)
[19:06:13] <Jymmm> Tom_itx: bottom chord = BACK
[19:10:03] <JT-Driod> Lost my connection
[19:11:10] <JT-Driod> Use 5v from the 5i25 as shown on my web page
[19:14:49] <micges> MacGalempsy: if you have 7i77 powered you should have 4 leds on
[19:15:01] <micges> left up, center, center , right down
[19:16:21] <CaptHindsight> JT_Shop: what is the name of the storefront that you use for the cycle parts?
[19:19:33] <CaptHindsight> nevermind, found it http://www.opencart.com/
[20:05:31] <MacGalempsy> thats what it was, wired to get power from the 5i25 and JT's files worked fine
[20:05:40] <MacGalempsy> now time to DRO came up
[20:05:43] <MacGalempsy> oops
[20:39:25] <MacGalempsy> ah this is going mucho bueno
[20:44:53] <PetefromTn> Congrats Mac.... The mesa cards are nice huh... Gotta get to bed here good luck with it.
[21:40:21] <pzpz> i'm here...
[21:41:13] <kwallace1> How far have you gotten on your machine?
[21:41:39] <pzpz> i want to buy in in 2 weeks..
[21:41:41] <MacGarage> dro readout
[21:41:44] <MacGarage> estop
[21:41:59] <MacGarage> x limit switches and y switch
[21:42:08] <MacGarage> working on z limits now
[21:42:16] <pzpz> what?
[21:42:57] <kwallace1> MacGarage is getting his machine wired up.
[21:43:15] <pzpz> ohhhhhhh
[21:43:37] <pzpz> i start to write to him...
[21:43:39] <pzpz> hehe..
[21:43:42] <pzpz> funny.
[21:45:41] <pzpz> 90V motor is a problem?
[21:46:06] <kwallace1> That's what I have on my lathe.
[21:47:07] <kwallace1> 90 Volt motors used to be common on machines, now they have higher voltage.
[21:47:53] <pzpz> what do you mean by "higher voltage"
[21:47:59] <pzpz> 90V is the max..
[21:48:17] <pzpz> more you will burn it..
[21:49:14] <kwallace1> It is common for modern CNC machines to use higher voltage for their motors.
[21:50:01] <kwallace1> The more voltage the faster you can go.
[21:51:58] <pzpz> 3000 rpm in the X/y is 70mm / s
[21:52:19] <pzpz> more than enough for me
[21:53:28] <pzpz> and with ball screws 5 TPI it will 250mm / s
[21:54:11] <pzpz> it is very very fast for what i need
[21:54:19] <pzpz> so..
[21:54:30] <pzpz> i go with this motor
[21:55:45] <kwallace1> You already have motors?
[21:55:53] <pzpz> http://www.kelinginc.net/KL34-180-90.pdf
[21:55:56] <pzpz> no
[21:57:14] <pzpz> what controlers i need for it?
[21:58:20] <pzpz> to connect the motor to the 5i22 mesa board
[21:59:51] <pzpz> ?
[21:59:57] <pzpz> kwallace1, ?
[22:00:19] <kwallace1> LinuxCNC and the 5i22 is your controller, you need amps for brushed motors, such as the Pico or Mesa PWM amps.
[22:01:27] <kwallace1> http://pico-systems.com/pwmservo.html
[22:02:22] <pcw_home> a 5I22 is probably overkill for almost any CNC application
[22:03:38] <pzpz> pcw_home, take a look http://pastebin.com/zMcBVz1B
[22:06:04] <kwallace1> My take on it is, 8 pwm signals with encoders, the rest is simple GPIO.
[22:08:08] <pzpz> the pico systems are good?
[22:11:01] <pzpz> i cant find "amps" in mesanet
[22:12:00] <kwallace1> Yes their controllers and amps work well, but I also look at the Mesa bits for my new projects.
[22:12:21] <micges> pzpz: http://mesanet.com/motioncardinfo.html
[22:14:31] <kwallace1> Maybe the 7i40
[22:15:14] <pzpz> http://store.mesanet.com/index.php?route=product/product&filter_name=7i29&product_id=141?
[22:17:25] <kwallace1> 2kWatts is about 2.5 hp, kind of overkill.
[22:17:25] <pzpz> http://www.kelinginc.net/KL34-180-90.pdf
[22:18:12] <pzpz> 3400W motor!?!
[22:18:33] <pzpz> yes it is over kill...
[22:19:08] <pzpz> errrr i need to buy it and use torqe meter
[22:20:44] <pzpz> i need to select the PWM amps by the Continuous Current or the Peak Current??
[22:20:55] <pcw_home> Peak
[22:21:05] <kwallace1> The motor is around 700 Watts
[22:21:14] <MacGarage> realized they all work. just dont have enough strength to pull up the z axis all the way
[22:21:50] <kwallace1> No up on the Z axis?
[22:21:58] <MacGarage> its there
[22:22:03] <MacGarage> and I tested the button
[22:22:23] <MacGarage> but between the wieght and the old cold grease, I cannot left the z axis all the way to the limit
[22:22:55] <pzpz> MacGarage, what machine you have?
[22:23:03] <MacGarage> benchman xt
[22:23:47] <kwallace1> The Benchman is what you need pzpz.
[22:23:48] <MacGarage> going into the house to take a break. after getting on my knees in the garage, my back hurts!
[22:25:59] <pzpz> OMG it is looook soooo sweeeeet
[22:26:05] <MacGalempsy> thanks
[22:26:30] <MacGalempsy> the wiring has been a bugger, but i know what everything should do, so now its just interface time
[22:26:37] <kwallace1> I think this is it? http://www.ebay.com/itm/121183132008
[22:26:48] <MacGalempsy> that be the beast
[22:27:18] <MacGalempsy> http://www.machinetoolsonline.com/doc/benchman-xt-industrial-cnc-machining-centers-0001
[22:27:36] <MacGalempsy> mine is the 2HP, 4th axis and 20 tool atc
[22:27:37] <pzpz> more then 3 time then what i want to spand...
[22:27:51] <MacGalempsy> i ended up giving him 5
[22:28:20] <MacGalempsy> but between shipping and tooling, we're up to 7 or 8
[22:28:34] <pzpz> and opss Net 800 lbs (363 kg)
[22:28:45] <pzpz> cant lift it..
[22:28:57] <MacGalempsy> time to hit the gym ;)
[22:29:15] <MacGalempsy> actually, I have the meat heads from the gym on call to come lift it onto the stand my uncle is welding up
[22:29:30] <pzpz> time to hit the machin with the gym....
[22:29:44] <MacGalempsy> except, he didnt finish before he went on his cruise
[22:29:54] <MacGalempsy> so now got to wait until he gets back.
[22:30:54] <pzpz> 300 Kg on old wood floor ...
[22:31:03] <pzpz> amazing..
[22:32:18] <pzpz> i will stay with the G0704...
[22:35:46] <MacGalempsy> I looked at one of those on ebay when the search was on, but after seeing this one, the precission is way better and its made in US
[22:37:15] <pzpz> but i want it as a hobby..
[22:37:34] <pzpz> not to open a factory..
[22:40:06] <jdh> quite the huge difference in price.
[22:42:00] <pzpz> yes.. 1:10
[22:43:23] <jdh> I have about $2k in my G0704
[22:44:01] <pzpz> what motor you use?
[22:44:22] <jdh> keling 540oz 23's
[22:44:35] <pzpz> stepper?
[22:44:41] <jdh> yep
[22:44:57] <jdh> cheap motors and drivers, 48v
[22:45:23] <pzpz> what drvers?
[22:45:49] <jdh> I don't remember the model, Low-end keling
[22:46:01] <jdh> I'd buy better ones if I did it again.
[22:46:46] <pzpz> and you covert to ball screw?
[22:46:52] <jdh> yep
[22:47:20] <pzpz> where you get them?
[22:47:44] <jdh> linearmotionbearings2008 guy chai
[22:48:03] <pzpz> ?????
[22:48:30] <pzpz> ohh i see
[22:48:40] <pzpz> ebay..
[22:49:19] <jdh> kind of. I just told him what I wanted (hoss plans) and he gave me a quote and I paid ($200 shipped)
[22:50:08] <pzpz> and it fit with the regular bearings?
[22:50:18] <pzpz> what is hoss plans?
[22:50:49] <jdh> https://www.google.com/search?q=hoss+g0704
[22:51:32] <pzpz> http://www.g0704.com/ ?
[22:51:35] <pzpz> this?
[22:51:37] <MacGalempsy> pzpz: the way I look at it is that if I can buy and industrial machine for the price of a hobby machine, why not?
[22:51:58] <RyanS> How come every time someone asks about VFDs (particularly on CNC zone), everyone says TECO... There would have to be 100 different manufacturers
[22:52:12] <jdh> teco is cheapp
[22:52:32] <RyanS> Is that it
[22:52:58] <RyanS> are Chinese ones off eBay bad?
[22:53:27] <pzpz> jdh, http://www.g0704.com/Shop_Info.html#ballscrews
[22:53:29] <pzpz> this?
[22:54:36] <pzpz> jdh, you can tap with the G0704?
[22:54:37] <jdh> he has a set of plans for sale.
[22:55:03] <jdh> makes it really easy to do the conversion, but there is nothing you couldn't do without them.
[22:55:36] <pzpz> i'm expert in solidworks..
[22:55:38] <MacGalempsy> pzpz: the g0704 is basically a drillpress with cnc axes
[22:55:49] <MacGalempsy> so why not just use a tapping head?
[22:56:22] <jdh> tapping head is expensive and takes up a lot of Z
[22:56:28] <MacGalempsy> depending on the spindle motor, the machine may not go slow enough, or be able to reverse fast enough
[22:56:51] <pzpz> to make individual small spindle for it?
[22:57:52] <pzpz> there is a way to control the motor?
[22:58:03] <pzpz> like speed and dir..
[22:58:24] <MacGalempsy> with that machine, you would probably be best off manually tapping
[22:58:44] <MacGalempsy> or, you could run a thread mill
[22:59:08] <pzpz> what is a thread mill?
[22:59:34] <jdh> speed is easy. dir requires more
[23:00:12] <jdh> you could get a 3phase motor and a TECO VFD
[23:00:29] <MacGalempsy> im not at the point of actually machining yet, but im feeling it is close
[23:00:31] <pzpz> the motor is not universal motor
[23:00:33] <jdh> but, most of the cheap motors seem to be too heavy.
[23:00:42] <RyanS> lol, teco :p
[23:00:43] <pzpz> so you can go DC..
[23:00:49] <jdh> g0704 is a 90v dc motor
[23:01:04] <jdh> I through the teco in for you.
[23:01:10] <jdh> or threw
[23:01:29] <RyanS> Speaking of tapping do you necessarily need a capacitor brake to do it on a VFD converted drill press?
[23:02:25] <pzpz> if it is a DC the G320X not work?
[23:02:31] <pzpz> 80V 20A
[23:02:33] <RyanS> Why should it matter how quickly it reverses?
[23:03:54] <kwallace1> If you run out of turns on the tap you're out of luck.
[23:04:21] <RyanS> I don't follow
[23:04:35] <pzpz> RyanS, mee too
[23:06:06] <kwallace1> The way I see it, you spin the tap and start the hole, you stop the VFD but it doesn't slow down very quickly and you run out of turns on the tap.
[23:06:49] <RyanS> Why not just stop it earlier. Once you get used to the timing
[23:06:54] <pzpz> kwallace1, but it is not ON/OFF
[23:07:21] <pzpz> you have acceleration..
[23:07:44] <kwallace1> The VFD won't command a reverse until the motor comes to a stop.
[23:07:45] <pzpz> you need servo spidle
[23:08:09] <kwallace1> Or use a cheap resistor, works a treat.
[23:08:29] <pzpz> or use servo
[23:08:39] <RyanS> I just can't imagine tapping working very well with vfd
[23:08:54] <RyanS> how on earth do you tap Properly with a VFD if you have to reverse the quill by hand?
[23:09:20] <MacGalempsy> you dont, most vfd wont reverse fast enough
[23:09:34] <pzpz> but you can use bit for trading.
[23:10:27] <MacGalempsy> thread mill baby. they are expensive, but you can machine with a vfd
[23:10:52] <RyanS> MacGalempsy I think if you have a capacitor brake They do?
[23:11:18] <MacGalempsy> maybe with a brake that would work, but you would have to ask someone who has tried it
[23:11:34] <kwallace1> https://www.youtube.com/watch?v=Zxw7HaD_kxk
[23:11:37] <MacGalempsy> my machine has no brake, and to get a replacement with one would be about 2k
[23:13:01] <pzpz> https://www.datrontooling.com/index.php?_a=category&cat_id=19
[23:13:07] <kwallace1> VFD's can reverse very well, with a braking resistor and proper settings.
[23:13:22] <MacGalempsy> kwallace1: how do you get the machine to revers?
[23:13:24] <Valen> spindle synchronised motion ftw
[23:13:25] <MacGalempsy> so fast?
[23:13:28] <pzpz> regular spindle..
[23:14:00] <RyanS> I would assume, though that when the spindle reverses the tap will push the quill back up If you hold the handle loosely?
[23:14:13] <kwallace1> Within a turn at tapping speeds.
[23:14:31] <pzpz> why not use this.... https://www.datrontooling.com/index.php?_a=category&cat_id=19
[23:15:06] <MacGalempsy> pzpz look at the price of those dudes. way more expensive that an tapping head
[23:15:27] <pzpz> is datron....
[23:15:34] <RyanS> not on a drill press . You can't :)
[23:15:34] <MacGalempsy> wonder if my vfd will reverse that fast
[23:15:56] <pzpz> i send it for the shape of the bit.
[23:17:54] <RyanS> I'm thinking of upgrading froma bench drill press, and getting a three-phase drill from the start and adding vfd
[23:18:12] <RyanS> http://res3.graysonline.com/handlers/imagehandler.ashx?t=sh&id=1847922&s=gl&index=0&ts=634830121023630000
[23:18:27] <RyanS> This is the motor of the one thinking of
[23:18:39] <RyanS> 1400rpm
[23:18:47] <kwallace1> For tapping on a drill press, I would use a VFD with a dual foot peddle for forward and reverse.
[23:20:16] <pzpz> or you can tapping with a spring holder.
[23:20:40] <pzpz> and do the tapping manualy
[23:21:14] <RyanS> I suppose it isn't that much of a hassle unless you need to tap 1 million holes
[23:22:34] <RyanS> This drill press has something which sounds like is badly translated from the manual "smooth running and long lived industrial motor with frequency converter extreme engine powered, wide constant torque progression
[23:22:50] <RyanS> WTF are they talking about
[23:23:16] <RyanS> That sounds almost like a VFD
[23:23:55] <kwallace1> Actually a simple tap fixture works well: http://www.chronos.ltd.uk/acatalog/info_41126001.html
[23:24:00] <pzpz> take it a parts.. and looking for a VFD :)
[23:24:32] <RyanS> Extreme engine that sounds hilarious
[23:25:17] <pzpz> kwallace1, you can do the same with a drill press
[23:25:32] <RyanS> uber extreme beefy industrial
[23:28:00] <pzpz> someone try the TTS?
[23:30:36] <pzpz> ?
[23:31:25] <RyanS> I heard its pretty convenient and simple to implement tts
[23:32:15] <RyanS> But I think some people say the tools can come out during milling, but a few the owners of the machines said it wasn't a problem
[23:32:27] <pzpz> but the power drawbar look complicated..
[23:33:03] <RyanS> I don't think it is. It's just a stack of Bellville washers
[23:34:05] <RyanS> And the actuator presses down on them to open the r8 collet
[23:34:53] <pzpz> but if i make a sqweez of half a ton on the bering it can make it go wrong...
[23:36:30] <RyanS> I would guess just presses down on the collet slightly out of the tapering therefore it opens up and releases the tool
[23:38:01] <pzpz> i want to make it quiet and electric
[23:38:28] <RyanS> hmm I think electric would be easier because you don't need a compressor
[23:39:44] <kwallace1> MacGalempsy: I finally found a proper video : https://www.youtube.com/watch?v=0qFv-TAM22U
[23:39:49] <pzpz> i dont want a compressor in the middele of my home..
[23:41:51] <pzpz> RyanS, but in tapping you need to go slooooow...
[23:44:12] <pzpz> go with 50-60 RPM and the brake will be fast.
[23:44:51] <RyanS> is 1400 rpm motor any good for a VFD?
[23:47:52] <pzpz> or you can do this..https://www.youtube.com/watch?v=EGhjsAOjfzU
[23:50:07] <Valen> by dad does most of his tapping with a battery drill
[23:52:40] <pzpz> Valen, it work to but if you need it very centerd - drill press will work file
[23:52:47] <pzpz> fine*
[23:54:38] <MacGalempsy> ok midnight reports are done. now to look at how to activate the zbrake when moving the z axis
[23:55:21] <RyanS> Just hold the tap in your teeth and rotate your head :p
[23:55:50] <MacGalempsy> !
[23:55:52] <MacGalempsy> hahaha
[23:55:55] <kwallace1> MacGalempsy: Did you see the VFD video I posted?
[23:56:28] <MacGalempsy> sorry was working on a report. let me look back
[23:57:11] <pzpz> LOL
[23:57:22] <MacGalempsy> what is a braking resistor?
[23:58:48] <MacGalempsy> that is pretty amazing how fast that stops
[23:59:23] <MacGalempsy> I saw in the digital drive report that the machine slows down at a few hundred rpm per second
