[04:28:07] <t4nk684> WELP!
[04:28:12] <t4nk684> wrong channel
[05:38:12] <jthornton> yikes
[05:53:48] <jthornton> Tom_itx, I woke up to a bunch of payments for my new air filters! The store is finally taking off.
[05:54:33] <archivist> better get shipping then :)
[05:57:45] <jthornton> yea, I just got the parts bag kitted up last night so now I need to pack the box and write the instructions
[06:00:48] <Loetmichel> yay, asiashop has delivered... DINNER! (at work) -> http://www.cyrom.org/palbum/main.php?g2_itemId=14805
[07:25:42] <Tom_itx> good stuff
[07:28:36] <R2E4> mornin
[07:40:13] <R2E4> well, the spindle still not working. I think I have to bring in Fanuc.
[07:48:08] <rob_h> do you have the full intergration manual R2E4?
[07:50:29] <R2E4> no, just have the maintenance manual
[07:51:24] <R2E4> Before, I could not turn the spindle, now the spindle I can turn all the time wether the machine is on or off. enabled or disabled
[07:51:35] <R2E4> its getting worse.
[07:52:18] <R2E4> Fanuc doesnt want to play. They will send someone out at 180/hr.
[07:53:40] <rob_h> i found them usefull in past .. whats the model number
[07:53:49] <rob_h> i have a range of manuals u might be lucky
[07:53:53] <rob_h> what was the old control?
[07:54:07] <rob_h> is it Alpha ? early or late
[07:55:25] <R2E4> early, the motor is A06B-1003 B300, Drive 53425E with A20B-1001-0120 with orientation board A20B-008-0030
[07:55:32] <skunkworks> is there a brake?
[07:55:44] <skunkworks> seems odd to me that you couldn't turn the spindle before...
[07:55:51] <R2E4> The old control is hitachi seikli seicos
[07:56:08] <rob_h> motor is all black then, no red top
[07:56:15] <R2E4> no red top
[07:56:22] <rob_h> so alpha
[07:56:23] <rob_h> ok
[07:56:46] <R2E4> http://www.ebay.com/itm/FANUC-A06B-1003-B300-AC-SPINDLE-MOTOR-MODEL-3-1500-6000-RPM-/380813881109? thats the motor
[07:56:48] <rob_h> i will have a look later on see what info i have
[07:56:54] <R2E4> ok thanks
[07:57:26] <rob_h> next size motor down to what we have on all our mills
[07:57:35] <R2E4> The spindle seems real easy to turn, too easy, dont know if the servo is turning also.
[07:57:59] <rob_h> servo
[07:58:28] <skunkworks> I would be more worried that it didn't turn originally...
[07:58:55] <archivist> does it have a backgear
[07:59:10] <rob_h> is it gearboxed?
[07:59:35] <R2E4> I dont know. I suspect it does cause their is a low gear input
[07:59:44] <rob_h> is on all drives
[07:59:52] <rob_h> infact i think fanuc drives have 7 gear input
[07:59:54] <archivist> if so then in low it would be hard to turn
[08:00:07] <R2E4> I dont think so, cause I see no place for it
[08:00:12] <rob_h> A20B-1001-0120 is top card number i think
[08:00:18] <rob_h> onside of drive is the drive number it self
[08:00:58] <R2E4> I looked last night and couldnt find it on the inside.
[08:01:08] <rob_h> its on left or right
[08:01:15] <rob_h> on outside
[08:01:28] <R2E4> B-53425E is what I had before, thats what Fanuc told me
[08:02:45] <R2E4> http://irmtl.com/LinuxCNC/VM40/Spindle%20Servo/sp2.JPG
[08:03:04] <rob_h> aah ha
[08:03:10] <R2E4> The display allways shows 000000
[08:03:13] <rob_h> should have manual for that, its same as in my CHNC
[08:03:28] <rob_h> i think it shows speed as fault or something
[08:03:31] <rob_h> default
[08:03:45] <R2E4> OMG...... cool
[08:04:16] <rob_h> i think model number is more like, A06B-6055-H106
[08:04:23] <rob_h> but end numbers change in drive sizes
[08:04:25] <R2E4> Went through the whole retrofit, everything is working up until the spindle....lol
[08:04:42] <R2E4> A06B-6044-h103
[08:05:41] <rob_h> i found what you might need, but each manual is 30mb or so so probly exceed your inbox limit for email
[08:06:14] <R2E4> Can you dump it on my server scp?
[08:07:37] <CaptHindsight> interesting about Fanuc at $180/hr, who do you get a tech, engineer, someone that knows what they are doing?
[08:09:42] <rob_h> yea
[08:09:48] <Valen> rob_h: there are ways of transferring large files outside email these days ;->
[08:09:53] <rob_h> and they also look up machine serial number and bring out every board in the machine to fix it
[08:11:02] <R2E4> The only Fanuc parts in it is the spindle servo and drive
[08:12:06] <R2E4> The guy was ok when I talked to him,. He didnt know anything, he said he would have to send an engineer out. There are two in Montreal, one guy is new and the opther is an older guy thats been doing it for ecver he said
[08:13:16] <CaptHindsight> will they be of any help since you have retrofitted the machine? They understand how they built the machine. They would be clueless with all the changes.
[08:14:15] <R2E4> Yes but it is opnly the spindle drive and servo. They should be able to see whats going on right away. every other wire in the machine is not their buisness
[08:14:43] <CaptHindsight> you'd think, but you're far more optimistic than me :)
[08:14:48] <R2E4> 4 setup wires to put the drive in function, plus power
[08:15:15] <R2E4> hehe, yeah, I would probablty spend 4 hours explaining what I did before he would touch it.
[08:15:22] <CaptHindsight> so 16 possible states
[08:16:37] <R2E4> not really. input estop, input sp forward, Mready and low gear
[08:16:53] <R2E4> need all 4 to work.....
[08:16:59] <R2E4> from what I see
[08:18:10] <CaptHindsight> 4^2=16 is what I meant, are you just getting fed up and rather have them help or are you still looking for help here?
[08:18:32] <R2E4> http://irmtl.com/vm40/SP-schematics.pdf
[08:18:55] <R2E4> No, I am looking for help here
[08:19:18] <CaptHindsight> there's that emotional factor as well :)
[08:20:08] <R2E4> I see what your saying, I would think would need all 4 before spindle starts spinning
[08:20:43] <CaptHindsight> ^^ that is the actual wiring diagram for your exact drive?
[08:20:44] <R2E4> I dont think its broke, I think I am doing something wrong....lol
[08:21:07] <R2E4> That is the machine schematics that came with the machine
[08:21:40] <R2E4> Those pins I verified on the cable and connectors
[08:22:06] <CaptHindsight> E-STOP should be OPEN, now we're down to only 8 states
[08:22:49] <R2E4> oh, I was closing it. Tried it open as well
[08:23:28] <R2E4> What e-stop is open? IF a wire breaks or disconnects, you wont know.
[08:23:38] <CaptHindsight> try the others OPEN as well
[08:24:00] <R2E4> I tried all open as it shows.
[08:24:42] <CaptHindsight> how about the thermostat? is that built into the motor and normally closed?
[08:24:59] <rob_h> should alarm about that
[08:25:12] <R2E4> yeah, thats in the motor
[08:25:23] <rob_h> or its wired into estop chain
[08:25:57] <R2E4> externally it is not.
[08:26:21] <R2E4> you guys are giving me life again...lol
[08:27:46] <R2E4> It would alarm on thermostat open.
[08:28:25] <rob_h> depends on type in motor but yes they are normaly closed
[08:28:32] <rob_h> then heat up and become open
[08:29:00] <CaptHindsight> I'm wondering about the 5 signals above the ANALOG input for speed/direction control
[08:30:03] <R2E4> The 5 above are outputs
[08:30:24] <rob_h> he means ones shown as Sp.forward sp.reverse. low gear etc i think
[08:30:54] <CaptHindsight> ok, that seems to make it easier
[08:30:54] <rob_h> normlay you just close estop, ready, sp.forward then input a analog should go forward
[08:31:22] <R2E4> ok, rob, thats what I thought, and I tried but it didnt go.
[08:31:32] <CaptHindsight> and we know that this is a good servo drive?
[08:31:50] <CaptHindsight> and good motor and encoder?
[08:32:20] <R2E4> I was told it was running when they shut it down. I have a friend that saw it running a month before they shut it down.
[08:32:54] <R2E4> There's no encoder on it. Theres a magnetic sensor, used for orientation
[08:33:11] <CaptHindsight> encoder/pulse generator
[08:33:26] <rob_h> sensor is inside motor in the top
[08:33:34] <rob_h> its a Sine cosine output
[08:33:43] <rob_h> drive uses it for a speed reff
[08:34:29] <CaptHindsight> the correct AC power is input?
[08:34:34] <rob_h> just A and B chan.. alpha motors sometimes have a Z chanel if they do regid tapping as saves adding a encoder driven from spindle belt
[08:34:53] <CaptHindsight> I'm just asking about the basics since sometime little dumb things get forgotten
[08:35:09] <rob_h> yea
[08:35:19] <R2E4> yes 220 3ph good in.
[08:35:35] <rob_h> well im heading back to work now :)
[08:37:32] <CaptHindsight> if everything is wired correctly then it should be working now
[08:38:43] <CaptHindsight> the motor windings check ok? can you swap motors or the servo drive? (shotgun method)
[08:39:07] <R2E4> I dont have any spares.
[08:40:58] <CaptHindsight> you've probably checked every connection, have you had someone else check it? I've had times where I just didn't see something obvious or assumed something was connected when it wasn't
[08:41:34] <CaptHindsight> like checking for typos :)
[08:43:01] <R2E4> yeah, thats a good idea, would have to find someone. i have a few candidates
[08:43:17] <CaptHindsight> at least it ALARMs when the thermostat is open
[08:43:32] <CaptHindsight> the drive isn't completely dead
[08:44:23] <CaptHindsight> why sometimes walking away and coming back later works
[08:45:05] <GuShH_> Because the universe simply hates us all
[08:45:37] <CaptHindsight> the pulse Gen is just 5VDC + and GND
[08:45:38] <R2E4> I will disconnect the inputs and redo them when I get there.
[08:46:05] <CaptHindsight> +/-A and +/-B
[08:46:34] <CaptHindsight> and a shield ground
[08:47:32] <R2E4> I didnt touch those connections. They go from motor to drive directly.
[08:49:17] <CaptHindsight> I see 5 connections, READY, SP FORWARD, SP REVERSE, LOW GEAR and ORIENTATION
[08:49:53] <CaptHindsight> you mentioned 4
[08:50:30] <R2E4> yup, those are the ones. I omitted orientation cause that is needed when you want to orientate the spindle for tool change.
[08:50:53] <CaptHindsight> is it OPEN?
[08:51:12] <R2E4> yes, I didnt connect it
[08:51:31] <CaptHindsight> what's the voltage on G2?
[08:51:38] <R2E4> G2 is gnd
[08:51:53] <CaptHindsight> it also has to go to OS
[08:52:22] <R2E4> yes, theres no pin for it.
[08:53:59] <CaptHindsight> where? no OS pin/connection on the drive? or?
[08:54:44] <CaptHindsight> drawings can also be wrong, that makes it even more fun
[08:54:47] <R2E4> I am looking at the way it was wired in the machine. There was no connection to that pin. The connector that went to the old machine, did not have that pin connected.
[08:55:28] <CaptHindsight> ah there you go, a discrepancy already
[08:55:33] <CaptHindsight> frustrating
[08:56:07] <R2E4> I found a few when doing the X,Y,Z drives
[08:56:56] <CaptHindsight> have you tried a 9V battery on the Analog input?
[08:58:06] <R2E4> no.
[08:58:29] <R2E4> I did that with the xyz drives.
[08:58:42] <CaptHindsight> ok, that was you
[08:59:05] <CaptHindsight> I think I noticed you working on this for a while
[08:59:15] <R2E4> been a couple months now
[08:59:46] <R2E4> its is working so far, I can run gcode, control panel buttons working etc....
[09:00:40] <CaptHindsight> it happens, we are about to ship a system and now last minute crazy behavior
[09:01:50] <CaptHindsight> nut thats a low price for a spindle motor like that
[09:02:19] <skunkworks> heh - people are arguing on the mach list about linux vs ms.. (about xp EOL)
[09:02:29] <R2E4> not again
[09:02:57] <archivist> I hate versions of LTS going eol too :)
[09:03:26] <skunkworks> well - you know linux has security issues also.... let me point you to an article that show 1 or 2 exploits..
[09:03:52] <skunkworks> archivist: sure!
[09:03:56] <CaptHindsight> BSD-CNC?
[09:04:16] <CaptHindsight> Plan9-CNC
[09:04:30] <skunkworks> os-warp-cnc
[09:04:43] <CaptHindsight> but I guess it really should be QNX-CNC :)
[09:05:04] <CaptHindsight> real realtime vs our fake real time stuff
[09:06:32] <skunkworks> Those are fighting words!! ;)
[09:07:09] <CaptHindsight> $350 for a 6K rpm 5.5KW motor, I guess you don't know the shape of the bearings, but if nothing else is worn + $300 for bearings
[09:07:58] <R2E4> I would venture to say the drive would be bad before the motor
[09:08:13] <R2E4> Thats one heavy duty servo
[09:10:54] <CaptHindsight> what's a good simple way to stop Linuxcnc from running a program? Let's say Linuxcnc can run but just not RUN G-code without an additional password or something
[09:30:08] <CaptHindsight> R2E4: have you tried grounding OS anyway?
[09:35:16] <zeeshan|2> R2E4: i told you!
[09:35:24] <zeeshan|2> R2E4: they send out a technician for that much
[09:36:57] <CaptHindsight> if the tech brings out another servo drive and it runs problem solved
[09:37:32] <R2E4> I dont have access to that pin
[09:37:44] <R2E4> zeeshan|2: yeah I know
[09:37:50] <zeeshan|2> bloody expensive
[09:38:00] <CaptHindsight> an issue might be that he won't swap drives with non-original wiring since it could fry his new drive
[09:38:07] <CaptHindsight> or ask you to be liable
[09:38:16] <R2E4> probably plus travel.
[09:38:25] <zeeshan|2> prolly no travel
[09:38:27] <CaptHindsight> and wait until the drive is certified ok
[09:38:31] <zeeshan|2> if you have him there for a minimum number of hours
[09:38:38] <zeeshan|2> i think 3
[09:38:59] <CaptHindsight> for that price you can buy a used servo drive just for testing
[09:39:05] <zeeshan|2> i think the most annoying part you'll find for having the person come there is
[09:39:15] <zeeshan|2> telling you that you're doing it all wrong
[09:39:15] <zeeshan|2> lol
[09:39:20] <zeeshan|2> even though you're doing it right
[09:39:23] <CaptHindsight> heh yeah
[09:39:24] <zeeshan|2> and waste your time like that.
[09:39:36] <zeeshan|2> and you shouldn't bother and get their i series controller.
[09:39:58] <zeeshan|2> in other words, i think it will be useless for having a technician come there
[09:40:45] <zeeshan|2> if your motor is an alpha series
[09:40:48] <zeeshan|2> its in that zip file
[09:40:52] <R2E4> whats their i series controller cost? 10,000.00?
[09:40:54] <zeeshan|2> the operation manual
[09:41:06] <CaptHindsight> you can get a used AB servo drive for $200
[09:41:21] <zeeshan|2> its about 20k new
[09:41:23] <R2E4> For that servo?
[09:42:00] <R2E4> yes but the problem with that is the orientation circuit
[09:42:12] <CaptHindsight> it would be smaller, but it would turn the motor without load, then after testing you could resell the AB drive
[09:43:35] <zeeshan|2> R2E4: what is the problem?
[09:43:50] <R2E4> zeeshan|2: The spindle dont spin
[09:43:57] <zeeshan|2> you have it all wired right?
[09:44:15] <zeeshan|2> you said earlier
[09:44:16] <zeeshan|2> you got it spinning
[09:44:20] <zeeshan|2> whether the machine was on or off
[09:44:30] <R2E4> I can turn it by hand
[09:44:59] <zeeshan|2> can you ever not turn it by hand?
[09:45:17] <R2E4> before it wouldnt turn by hand
[09:45:38] <zeeshan|2> that's good
[09:45:41] <zeeshan|2> at least you know its getting power
[09:45:42] <CaptHindsight> how was it wired in that BEFORE state?
[09:47:09] <R2E4> It wasnt wired up. just power, and no magnetic sensor. Since I have connected magnetic sensor and cycled the E-stop, it now turns with my hand
[09:47:33] <zeeshan|2> early, the motor is A06B-1003 B300, Drive 53425E with A20B-1001-0120 with orientation board A20B-008-0030
[09:47:36] <zeeshan|2> whoops
[09:48:09] <zeeshan|2> that drive part number
[09:48:11] <zeeshan|2> i dont think is right
[09:49:06] <R2E4> It is A06B-0644-H103
[09:49:14] <CaptHindsight> R2E4: can you disconnect the encoder/pulse gen/mag sensor and see if the motor locks up again?
[09:49:33] <R2E4> I dont know how they cross ref the B-53425E
[09:50:08] <zeeshan|2> honestly
[09:50:11] <zeeshan|2> in this thing where it says
[09:50:16] <CaptHindsight> so he could be using the wrong diagram?
[09:50:17] <zeeshan|2> how to select a servo amplifier for the spindle
[09:50:30] <zeeshan|2> it goes A06B-60xx-H103
[09:50:59] <R2E4> CaptHindsight: I can try that, but the magsensor is working, When I turn the spindle, the led's for orientation are correct, I can turn the spindle to the orientation it needs.
[09:51:16] <zeeshan|2> spindle amplifiers have the part numbers
[09:51:26] <zeeshan|2> spm x-xx
[09:51:43] <zeeshan|2> the first x is motor type 'alpha series, alpha C series'
[09:51:50] <R2E4> I am using the diagram that the machine was powered up with.
[09:52:06] <CaptHindsight> maybe it's stuck in E-STOP somehow
[09:52:46] <R2E4> I heard the contactors energized/de-energize when I set e-stop input
[09:53:24] <CaptHindsight> and you hear them turn on again when you release E-STOP?
[09:54:07] <R2E4> yes
[09:54:28] <R2E4> but last time I tried last night I didn't hear them.
[09:54:49] <CaptHindsight> and no matter what the spindle just spins free right now?
[09:54:54] <zeeshan|2> http://i.imgur.com/D8djWZw.png
[09:54:58] <R2E4> yes
[09:54:59] <zeeshan|2> does this look like your amplifier?
[09:55:34] <R2E4> no thats not it
[09:55:39] <zeeshan|2> doh ;p
[09:55:39] <CaptHindsight> http://irmtl.com/vm40/SP-schematics.pdf
[09:56:07] <R2E4> That is from the hitachi-seiki VM40 schematics
[09:56:17] <CaptHindsight> I have a mess to fix here, bbl
[09:56:30] <zeeshan|2> okay lemme see if i can find something similar
[09:57:03] <R2E4> Rob sent me the manuals to A06B-6055 and I am going throught hem, and I think they are correct.
[09:58:11] <zeeshan|2> according to that pdf
[09:58:25] <zeeshan|2> the wiring between the motor and drive is ok
[09:58:43] <zeeshan|2> i like how your motor has a thermostat built in
[09:58:44] <zeeshan|2> :D
[09:58:59] <R2E4> I didnt touch the connections between the motor assembly and drive.
[09:59:15] <zeeshan|2> youve been playing around with:
[09:59:25] <zeeshan|2> well obviously
[09:59:28] <zeeshan|2> you got r s t ground
[09:59:30] <zeeshan|2> hooked up right?
[09:59:33] <zeeshan|2> thats power.
[09:59:35] <zeeshan|2> duhh =D
[09:59:47] <zeeshan|2> sp. speed check signal, spd certain speed signal sp zero speed signal
[09:59:54] <zeeshan|2> spindle alarm
[10:00:01] <R2E4> Those are ooutputs
[10:00:03] <R2E4> outputs
[10:00:25] <zeeshan|2> so theres only 6 more signals left
[10:00:29] <zeeshan|2> e-stop
[10:00:39] <zeeshan|2> ready, forward, reverse, low gear, orientation
[10:00:56] <CaptHindsight> yeah, what i mentioned earlier, even mentioned to have someone else sanity check the connections
[10:01:06] <pcw_home> Some of these drives have a spindle brake done with a contactor in the motor leads is there anything like that?
[10:01:12] <R2E4> CaptHindsight: Yes, I am going to do that
[10:01:15] <zeeshan|2> OS looks like
[10:01:18] <zeeshan|2> common ground
[10:01:26] <zeeshan|2> actually its not
[10:01:31] <zeeshan|2> nm it is.
[10:01:46] <R2E4> pcw_home: The manual says that when command is removed the regenerative braking kicks in
[10:01:54] <CaptHindsight> I have wires crossed or wrong and I just didn't see it myself, like checking for typos in your writing
[10:02:08] <Loetmichel> *gnah... sometimes the chinese manufacturers forget to think. couldn't the made the rotational axis 8mm lower? -> http://www.cyrom.org/palbum/main.php?g2_itemId=14811&g2_imageViewsIndex=1
[10:03:19] <R2E4> I'll have another go at it this afternoon. Disconnect wiring, reqwire and have someone else check it.
[10:05:01] <R2E4> zeeshan|2: B-53422E do you have means of checking what this cross ref to as in drive # re: A06B-6055-H103
[10:05:47] <CaptHindsight> Loetmichel: that feature keeps the tools from getting worn :)
[10:06:32] <CaptHindsight> Loetmichel: your router looks similar, what model is that?
[10:08:47] <zeeshan|2> nope =/
[10:09:38] <Loetmichel> CaptHindsight: chinese CNC 6040
[10:09:40] <pcw_home> R2E4 command being forward or reverse?
[10:09:42] <pcw_home> I would also check the voltages at the forward/rev pins and see if the change when you enable them
[10:10:58] <CaptHindsight> pcw_home: are you using 14.04 with the 3.4 RTAI kernel?
[10:11:11] <R2E4> pcw_home: ok, the manual says it needs estop, sp forward or revers, and ready, if you remove sp forward or rewverse, it would cease the spindle
[10:15:55] <pcw_home> I tried 14.04 but had too many linuxcnc dependency problems
[10:17:05] <pcw_home> currently using 12.04 with 3.12.5 Preemt-RT kernel
[10:17:36] <CaptHindsight> pcw_home: any issues with 12.04 and Linuxcnc?
[10:19:06] <CaptHindsight> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNC_On_Ubuntu_Precise I've followed this but I havent't controlled any machines with it
[10:25:49] <zeeshan|2> http://hamilton.kijiji.ca/c-buy-and-sell-furniture-hutches-display-cabinets-Office-Metal-File-Cabinet-with-wheels-W0QQAdIdZ460125038
[10:26:00] <zeeshan|2> so im thinking of buying this today
[10:26:13] <zeeshan|2> http://i.imgur.com/knSHKUN.jpg
[10:26:22] <zeeshan|2> then mounting that mini drill press on the left and belt sander on top of it
[10:26:33] <zeeshan|2> (scrapping the base for the belt sander
[10:28:12] <zeeshan|2> trying to geet rid of these shelves (to make space for vertical bandsaw)
[10:28:20] <zeeshan|2> http://i.imgur.com/03ep4TD.jpg
[10:33:16] <CaptHindsight> is that a turbo on the shelf under the paint cans?
[10:34:12] <zeeshan|2> those are brake cleaner cans
[10:34:12] <zeeshan|2> !
[10:34:18] <zeeshan|2> and yes theres 2 sitting on the shelf
[10:34:18] <zeeshan|2> hehe
[10:34:38] <R2E4> Is that a small metal cutting bandsaw on the left of the shelf?
[10:34:45] <zeeshan|2> yes
[10:34:57] <zeeshan|2> it works okay in vertical mode
[10:35:02] <zeeshan|2> but nothing like a doall vertical bandsaw
[10:35:06] <zeeshan|2> which weighs 1000lb
[10:35:20] <zeeshan|2> like if you're trying to cut round stuff, forget about it
[10:35:23] <zeeshan|2> it just shakes everything
[10:35:36] <R2E4> Is that a fanuc spindle servo and cmpatable drive enclosed in that black box?
[10:36:07] <zeeshan|2> dude
[10:36:12] <zeeshan|2> do i look like im made of money?!?!
[10:36:13] <zeeshan|2> :D
[10:36:17] <zeeshan|2> fanuc belongs at work
[10:36:26] <zeeshan|2> automation technologies belongs at home
[10:36:26] <zeeshan|2> :)
[10:36:58] <R2E4> My Fanuc is on the home side.
[10:37:35] <zeeshan|2> i think the only fancy stuff i have
[10:37:46] <zeeshan|2> is vfds abb, eaton, and plcs allen bradley
[10:37:55] <zeeshan|2> but thats still relatively cheap compared to most fanuc stuff
[10:38:42] <JT-Shop> allen bradley and cheap don't go in the same sentence!
[10:38:58] <zeeshan|2> their micrologix drives are realtivelyy cheap
[10:39:06] <zeeshan|2> not driuves
[10:39:07] <zeeshan|2> plcs
[10:39:27] <R2E4> jeez! this manual shows a variation similar but not the same as the others
[10:41:15] <CaptHindsight> Loetmichel: did you have to rework your 6040 to get the lash out and also square it? The 4530's are a real mess to fix
[10:42:12] <Loetmichel> the squaring: yes
[10:42:15] <Loetmichel> las: no
[10:42:34] <JT-Shop> maybe relative to compact logix but not to automation direct plc's
[10:42:36] <CaptHindsight> Loetmichel: I see nuts on the ballscrews for setting preload
[10:43:04] <CaptHindsight> Loetmichel: the 4530's don't have threads, I have to shim each one
[10:43:14] <CaptHindsight> or i could replace the ballscrews
[10:47:54] <pcw_home> CaptHindsight no issues with 12.04 that I have noticed
[10:48:53] <pcw_home> have not messed with the 3.4.55 RTAI kernel since my current test machine needs 3.11 or >
[10:51:07] <CaptHindsight> yes, new hardware
[10:53:01] <pcw_home> strangely enough 2.6.122-RTAI works on the J1800 CPUs just no accelerated video
[11:08:32] <CaptHindsight> ubuntu always seems to default to VESA or flglrx for drivers, never the good stuff
[11:08:59] <CaptHindsight> the ubuntu devs never did understand how video works with Linux
[11:11:58] <R2E4> Thats probably why my linuxcnc gui is freezing sometimes.
[11:12:15] <CaptHindsight> R2E4: what hardware?
[11:13:41] <R2E4> Its an nvidia video card. Havent had time to research yet.
[11:13:50] <R2E4> MB dont know.
[11:14:20] <CaptHindsight> I haven't used Intel or nvidia in close to 10 years
[11:15:29] <pcw_home> maybe MB or video issue I would try a different video card first
[11:16:34] <pcw_home> can you still get a console when you get a GUI hang?
[11:17:06] <pcw_home> ( control alt F1 )
[11:17:26] <R2E4> yes, and the machine still runs the gcode
[11:17:31] <CaptHindsight> anyone have a favorite wired USB keyboard with trackball/pad for their Linuxcnc machines?
[11:18:19] <CaptHindsight> so X dies, which version Ubuntu?
[11:18:29] <pcw_home> I suspect nvidia (but I always suspect Nvidia)
[11:19:28] <R2E4> yeah, thats what I thought also. Any suggestions on which video card?
[11:19:41] <R2E4> from the livecd, and built from there.
[11:19:55] <CaptHindsight> we use all AMD
[11:20:19] <CaptHindsight> since I have access to docs we can fix anything
[11:20:30] <CaptHindsight> but we rarely need the docs
[11:20:39] <R2E4> AMD cpu?
[11:20:42] <pcw_home> does the MB have built in video?
[11:20:54] <CaptHindsight> cpu and gpu and now APU :)
[11:20:56] <R2E4> IT is a pci card.
[11:21:09] <Loetmichel> CaptHindsight: i use a regular mouse and a silicone foldable keyboard
[11:21:23] <Loetmichel> watertight and heat resistant
[11:21:29] <CaptHindsight> you can find old ATI PCI GPU cards
[11:21:40] <R2E4> Loetmichel: I have one of those
[11:21:42] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12569
[11:21:53] <CaptHindsight> Loetmichel: I used to used those as well
[11:22:24] <Loetmichel> they are not for typing longer essays, but grat for machine use when the Swarf is everywhere ;)
[11:22:43] <R2E4> I have some old video cards I'll try. I am not really concerned about that right now though. concentrating on the spindle
[11:22:48] <CaptHindsight> heh, I tried to use them for my desktop, got tired really fast
[11:23:08] <CaptHindsight> R2E4: you're close
[11:23:09] <Loetmichel> yeah, typing on these is a PITA
[11:23:21] <Loetmichel> but they are great for anything with water or heat
[11:23:32] <Loetmichel> s/or/and//or
[11:24:54] <CaptHindsight> R2E4: http://www.ebay.com/itm/ALLEN-BRADLEY-ULTRA-3000-2098-DSD-010-SE-C-V1-50-GOOD-USED-TAKE-OFF-/181342592587?pt=BI_Control_Systems_PLCs&hash=item2a38dc5e4b
[11:26:14] <CaptHindsight> IIRC those or similar can be used with your encoder
[11:26:36] <R2E4> The pulse generator?
[11:27:35] <CaptHindsight> yes, they take just about anything, even analog
[11:28:09] <R2E4> To test the motor? You sure that is strong enough for my motor?
[11:28:10] <CaptHindsight> pcw_home: what kind of encoder is on his motor? http://www.ebay.com/itm/FANUC-A06B-1003-B300-AC-SPINDLE-MOTOR-MODEL-3-1500-6000-RPM-/380813881109
[11:28:31] <CaptHindsight> http://irmtl.com/vm40/SP-schematics.pdf
[11:29:09] <pcw_home> probably just normal quadrature
[11:29:23] <R2E4> I would lose orientation though.
[11:29:32] <CaptHindsight> 5V and +/-A and +/-B
[11:30:08] <pcw_home> yep probably standard differential quadrature
[11:30:12] <CaptHindsight> R2E4: why do you think you'll lose orientation?
[11:30:15] <pcw_home> no index
[11:31:10] <pcw_home> is there some other sensor for orientation?
[11:31:28] <R2E4> magnetic sensor
[11:31:51] <R2E4> 4th page of http://irmtl.com/vm40/SP-schematics.pdf
[11:34:32] <CaptHindsight> we think that it's just standard quadrature 5V no index
[11:34:42] <CaptHindsight> a scope will verify this
[11:34:48] <pcw_home> and CNA is on the spindle drive?
[11:35:53] <R2E4> yes
[11:41:28] <CaptHindsight> http://www.ebay.com/itm/Allen-Bradley-2098-DSD-030-B-Ultra-3000-Servo-Drive-/380815380893?pt=BI_Control_Systems_PLCs&hash=item58aa5d919d this drive will do it
[11:41:34] <pcw_home> I would check the signals at the drive and make sure they are high when off and go low when active
[11:46:16] <R2E4> In the manual, each input has its own feed pin(gnd), the machie schematics show coming from one source. I dont think thats a problem cause thats how it was wired and working on the machine.
[11:57:13] <pcw_home> I would still check at the drive pins
[11:57:50] <CaptHindsight> broken wire, loose contact etc etc
[11:57:53] <R2E4> OK, looking for +v at the pins to go gnd when apllied input?
[11:58:34] <CaptHindsight> they are active LOW
[11:58:47] <R2E4> yes
[11:59:13] <pcw_home> we are assuming that...
[12:02:53] <R2E4> Going to the shop now to do some testing.
[12:06:07] <IchGuckLive> hi all B)
[12:06:30] <IchGuckLive> what a wonderfull day here in germany
[12:06:52] <CaptHindsight> we had spring here yesterday, now back to winter
[12:07:25] <CaptHindsight> then 20C, now -1C
