[00:04:01] theorb is now known as
theorbtwo
[00:04:14] <joe9> JT-Shop: just wanted to check with you about this behaviour, when I have the quill all the way down and I press and hold the housing of the quill to the side, the runout is 0.002 inches.
[00:04:40] <joe9> but, when I leave it and check the runout of the spindle, the runout is 0.007 inches
[00:04:58] <joe9> JT-Shop: is your 0.006 inches runout at the chuck or the spindle?
[00:05:49] <JT-Shop> I just measured on my chuck as you piqued my curiosity
[00:06:03] <joe9> 0.006 inches at the chuck is pretty cool.
[00:06:05] <JT-Shop> but it doesn't affect the drilling any
[00:06:17] <joe9> mine is 0.020 inches at the chuck.
[00:06:33] <JT-Shop> blue the taper to the chuck fit
[00:06:43] <JT-Shop> do you know how to do that?
[00:06:45] <joe9> or, sometimes close to 0.03 inches.
[00:07:02] <joe9> no, I have never done "bluing". will see if I can do it.
[00:08:37] <JT-Shop> you smear a thin coat of something grease like on one part and put the two parts together and remove with care then see what areas the grease transferred to the dry part
[00:09:04] <JT-Shop> that shows you what parts touched
[00:10:51] <JT-Shop> the process is systematic to find the actual problem part, so if you mark the chuck and the shaft and assemble and indicate then rotate 1/4 turn and repeat you can figure if the chuck is bad or the taper or spindle is bad
[00:11:07] <joe9> ok, thanks.
[00:21:47] <SadMan> isn't there by chance a package with rtai kernel newer than 2.6.32?

[00:26:46] <raynerd> Hi guys, sure this is very obvious but have been working on my cnc machine for 2 weeks now and just these last few mins giving it its first 3 axis run of the emc2 splash screen. It is 12:30 midnight and I`m shattered but...
[00:27:03] <raynerd> when I`m cutting, I`m getting like an inverted image?
[00:27:26] <raynerd> so the EMC2 splash/demo looks like it is from behind.
[00:28:05] <alex4nder> your X is swapped?
[00:28:31] <raynerd> ahhh, could be...sorry tired, just wanted to go to bed happy.
[00:28:34] <raynerd> I`ll give it a go.
[00:31:03] <raynerd> nice one, thank you!

[03:43:21] <hatch789> anyone have any idea why my 7i49 board would not have any DC signal coming out for my servo drives? I just got the resolvers working today with PCW's help, but my servo drivers are not producing any voltage to drive my servos
[03:45:59] -!-
demacus_ has quit [Ping timeout: 245 seconds]
[03:46:09] <jdhnc> I assume you checked the power supply
[03:47:03] <hatch789> yeah ...my resolvers are working properly and picking up my movements on the handwheels
[03:47:36] <jdhnc> aren't they powered separately?
[03:47:40] <hatch789> for them to be working the board (7i49) has to be operating with the proper voltage and other things
[03:47:44] <hatch789> no
[03:48:01] <hatch789> the board gets it power from the 50 pin connector to my 7i43 card
[03:48:27] <pcw_home> 7I49 needs 2 enables and pwmgen set to mode 2
[03:48:43] <hatch789> I saw the 2 enables thing. But I didn't know what that meant?
[03:49:03] <jdhnc> ya know, you just can't beat the cost of Linuxcnc and the responsiveness of mesa guys
[03:49:04] <hatch789> pg12 enable inputs
[03:49:44] <hatch789> I have my pwmgen set to mode 2. It's been mode 2 since a few days ago
[03:50:01] <hatch789> but what's the 2 enable inputs that come from the FPGA?
[03:50:25] <pcw_home> they are from pwmgen enable
[03:50:42] <pcw_home> (both from ena 0 I think)
[03:53:22] <pcw_home> hm2_7i43.0.pwmgen.00.enable must be set true
[03:54:03] <hatch789> in my hal file? under the PWM Generator signals/setup section?
[03:55:07] <pcw_home> its supposed to be controlled by a linuxCNC or axis signal (take a look at the sample hm2 servo config)
[03:56:23] <hatch789> ok I will do that. this is what I have by the way in my PWM Generator signals/setup section
[03:56:24] <hatch789> net x-enable axis.0.amp-enable-out => hm2_7i43.0.pwmgen.00.enable
[03:56:44] <hatch789> then of course:
[03:56:44] <hatch789> net y-enable axis.1.amp-enable-out => hm2_7i43.0.pwmgen.01.enable
[03:59:46] <pcw_home> only 0 should matter
[03:59:48] <pcw_home> you can check that both pin 1 and pin 47 on the 7I49
[03:59:50] <pcw_home> 50 pin connector go low when you are in a machine on state
[04:01:29] <pcw_home> and trace in hal that they are true and the pwmgen value is reasonable relative to pwmgen scale
[04:02:38] <hatch789> I can't seem to find your hm2 servo config sample hal file?

[13:59:53] <archivist> look related to the ones I use

[14:00:07] <cncbasher> yes they are all the same
[14:00:42] <cncbasher> iv'e not had a bad one , at least not as yet
[14:01:03] <archivist> I had a dry joint in one
[14:01:13] <vin321> sweet & will i get away woth a 24 v power ?
[14:01:18] <cncbasher> even shorting out a motor it survived
[14:01:31] <vin321> cool
[14:01:42] <cncbasher> better with 36 - 48v
[14:01:44] <archivist> I run 28v
[14:01:49] <vin321> i meen i dont want to use 24 v but for now
[14:02:15] <cncbasher> 24 is fine for testing , you just wont get the speed

[14:03:00] <vin321> odds are to much speed with throw my thing to bits at this stage

[14:03:59] <cncbasher> you need around 10 amps for 3 of them

[14:06:49] <cncbasher> i use a lot of these , for stepper psu's

[14:07:50] <cncbasher> theirs plenty to choose from , but in the main modified computer supplys are a bit of a rough way to do it
[14:08:55] <cncbasher> also you cant beat a simple transformer , bridge rectifier and large caps
[14:09:06] <cncbasher> thats all you need
[14:09:54] <cncbasher> no seperate psu's and batts is not a clean way to do it
[14:10:17] <cncbasher> and problems and you'll blow the lot
[14:10:46] <vin321> thats how i killed my tb6560
[14:11:21] <cncbasher> tb6560's are easy to kill , all you need to do is connect it
[14:11:51] <cncbasher> they should be killed on sight
[14:12:08] <vin321> it was odd it worked at 36 them wem i changed back to 24 it poped
[14:12:42] <vin321> thing is i got it working
[14:12:51] <cncbasher> their a typical bad design layout made cheap , a few extra pennies and they would have been fine
[14:13:37] <cncbasher> in most badly spec'd components , but after all their made to a price of course

[14:14:31] <cncbasher> probably fine in very low amp steppers , but give them any real use and they will pop

[14:32:04] <cncbasher> yea their fine
[14:32:24] <cncbasher> but you do need a fair powersupply for them
[14:33:18] <cncbasher> be careful some stepper drivers are only 48v max
[14:33:41] <cncbasher> better to get the 60v + ones and a matching supply
[14:33:53] <cncbasher> what are you using them in
[14:33:59] <cncbasher> router ?
[14:34:22] <vin321> i guess
[14:34:47] <vin321> its got a gartry with a router straped to it
[14:35:23] <cncbasher> yea you better off with the higher voltage and current types
[14:35:35] <cncbasher> you have a lot of mass to move
[14:35:42] <cncbasher> with a gantery
[14:36:14] <vin321> ya its moisy to
[14:36:52] <cncbasher> if you have any friction or tightspots try and remove them
[14:37:00] <vin321> i realy need to change this keybord letters all worn & im desxic
[14:37:21] <cncbasher> the smoother it runs the better mechanicly
[14:39:17] <vin321> its fealy smoth y& x have 4 rails each tho as its made from plans of wood theres some flex at times
[14:39:40] <vin321> i got some pritty good resolts with that tb bord
[14:40:24] <vin321> not perfict but at lest i could see some progress
[14:41:18] <vin321> the biggest issue was x i think the bearings are to close to gather for the load there was a lil wobble

[16:20:38] <raynerd> Hi guys
[16:21:02] <raynerd> I`m absolutely gutted. Last night I got my cnc machine working on three axis and was hanging on here talking to a few people.
[16:21:46] <raynerd> Just got down to it now looking forward to the first time of proper use and the bloody power supply is tripping when connected to my 3-axis TB6560 board
[16:21:51] <raynerd> I`m guessing the board is screwed?
[16:22:50] <raynerd> Power supply comes on just fine when not connected to the driver, but then trips off when connected.
[16:22:55] <jdhnc> might try it one motor at a time.
[16:23:02] <archivist> TB6560 is not known for reliability, what was the voltage you had it on
[16:23:09] <raynerd> 12v
[16:23:15] <raynerd> and tried it with no motors!
[16:23:55] <raynerd> the little led comes on new the 12v vol reg when connected to parallel port but connecting a power supply just causes it to trip out.
[16:24:02] <raynerd> new = near
[16:24:47] <raynerd> I could cry, been building up to this day for frigging months
[16:26:02] <raynerd> any idea what could be happening on the driver board to cause the power supply to trip out when connected?
[16:26:12] <archivist> comment from someone else today <cncbasher> tb6560's are easy to kill , all you need to do is connect it
[16:26:30] <pcw_home> 12V should be really safe unless you disconnected DC power or motors live
[16:27:14] <raynerd> I`m fairly sure I haven`t done that and yes I was purposely keeping on 12v during testing
[16:27:16] <archivist> check for shorts, things getting hot etc
[16:27:47] <raynerd> the little fan doesn`t even come on.
[16:28:16] <raynerd> that was a stupid comment, sorry, the fan wouldn`t come on because the power supply is being knocked off!
[16:28:21] <archivist> use a dvm to check shorts on the rails
[16:28:33] <pcw_home> I'd be temped to power it with a lab supply, crank it up till you have a couple amps and see what gets hot
[16:28:53] <archivist> pcw_home, I do that too :)
[16:29:01] <raynerd> ok
[16:29:20] <raynerd> I presume when I find something getting hot, that could very well be the dead component
[16:29:25] <archivist> yup
[16:29:45] <pcw_home> (a an good milli voltmeter so see where the current is going for dead shorts)
[16:29:48] <archivist> or just the part in series with the faulty part
[16:30:43] <raynerd> pcw_home: sorry, could you just explain that bit
[16:30:46] <archivist> a dvm capable of measuring very low resistance is another way
[16:31:09] <raynerd> yes, so I have a multimeter,
[16:32:43] <pcw_home> If you have several paralled component, and one is a dead short (so no heat) you can trace where the
[16:32:45] <pcw_home> current is going by measureing small voltage drops along the current carrying traces
[16:32:46] <archivist> connect black to 0v, then use the red lead on the power rail and measure various points till you find the lowest resistance on the power rail, should be close to the shorted chip
[16:34:06] <pcw_home> Thats easier (but the contact resistance is somtimes larger than the short/trace resistance)
[16:36:52] <archivist> yup needs a 4/5 digit meter
[16:37:28] <pcw_home> The heat way usually works too as long as the shorted component has some resistance
[16:39:05] <pcw_home> even 0.1 Ohm will give you a very noticeable ~1W with 3 A

[16:42:54] <raynerd> guys, I`m back, sorry I went down to the workshop to look at it. OK, first thing before I`ve done any test with a multimeter is that I can power up just fine but when the parallel connector to the computer is put in the socket, it shorts my supply
[16:43:06] <raynerd> even my bench supply drops to 6v
[16:43:35] <archivist> check wiring
[16:44:17] <raynerd> can`t see anything wrong with the wiring. The lead is a standard parallel lead that came with the driver
[16:44:43] <archivist> your part of the wiring :)
[16:45:24] <raynerd> Sorry :( not with you. At present I`ve no wiring connected other than the parallel cable and dc input
[16:45:43] <archivist> if the board has opto isolators that symptom should be impossible
[16:46:02] <pcw_home> is your 12v supply floating?
[16:46:20] <archivist> what amps can the supply handle
[16:46:29] <raynerd> :-S floating?
[16:46:43] <archivist> is it going into limit due to being undersized
[16:46:49] <raynerd> I`ve just switched to a lab supply so it is doing the same with my 12v constant and lab supply
[16:47:11] <pcw_home> floating meaning neither terminal is grounded
[16:47:11] <archivist> at how many amps
[16:47:53] <raynerd> sorry, pcw-home, know your trying to help but I`m not clear what you mean. No, I don`t think either terminal is grounded.
[16:48:16] <raynerd> please bear in mind that it was working just fine before I went to bed last night
[16:48:36] <pcw_home> how much current flows with the lab supply connected?
[16:49:28] <pcw_home> maybe theres a 1/2 bad Hbridge so its shorted in one particular DIR (whicd changes if plugged into computer)
[16:49:28] <raynerd> the lab supply shows 0.12A at 13.5v when the parallel cable is connected but the voltage drops to a max of 6v locked when the cable is connected
[16:49:54] <pcw_home> at how much current?
[16:50:17] <raynerd> one second...let me take this laptop down to the machine so can give you proper info.
[16:50:27] <pcw_home> (when its at 6V)
[16:51:20] <archivist> at least 6v means no shorts probably
[16:51:57] -!-
ries has quit [Ping timeout: 255 seconds]
[16:52:10] <raynerd> OK, no parallel cable connected - all lights come on as expected and driver "looks" fine. 13v at 0.12A
[16:52:57] <raynerd> When parallel cable is connected and computer turned on - 6v at 0.54A
[16:53:26] <archivist> has the psu got a current limit
[16:53:35] <pcw_home> ok when at 6V leave it on a bit and see what gets hot
[16:53:52] <raynerd> It is a Kenwood PA18 and has a 2A limit
[16:54:01] <archivist> are the motors connected
[16:54:08] <raynerd> not at present
[16:55:01] <archivist> error! how can a psu drop to 6v below its current limit
[16:55:22] <raynerd> huh?
[16:55:50] <raynerd> that is what the PSU is telling me.
[16:55:54] <pcw_home> just a WAG: one 1/2 bridge is bad in one DIR (so affected by DIR = cable)
[16:55:55] <raynerd> the numbers on the front
[16:56:16] <archivist> turn the current limit up
[16:56:30] <pcw_home> so feel around for whats hot
[16:56:54] <raynerd> archivist :( OOPS!
[16:57:04] <raynerd> 13v, 1.26A
[16:57:07] <pcw_home> (.54 amp at 6V should be enough archivist is trying to burn you)
[16:57:32] <archivist> smoke should get out the bad chip now
[16:58:01] <archivist> you could switch off and feel for "warm"
[16:59:08] -!-
Tom_itx has quit [Ping timeout: 252 seconds]
[16:59:12] <raynerd> nothing hot
[16:59:23] <raynerd> at 12v, should I plug a motor in and see if I can run one?
[17:00:10] <archivist> you can try, but /me finds that current high for no motors
[17:01:48] <pcw_home> 13v, 1.26A shoud definitely get something hot (left on long enough)
[17:02:13] <pcw_home> thats about 15W
[17:02:35] <archivist> I would be expecting a cracking noise and smoke

pierp has quit [Client Quit]
[17:04:02] <pcw_home> yeah that power is going somewhere...
[17:04:39] <raynerd> big diodes at the front are getting hotter
[17:04:57] <archivist> unplug motors, use one motor at a time to test each drive
[17:05:14] <raynerd> ok
[17:05:29] <raynerd> ok, so just got x axis in now
[17:05:33] <raynerd> what am I looking for?
[17:05:49] <archivist> heat and does it work properly
[17:06:12] <raynerd> 12.5v at 1.19A - working fine
[17:06:16] <pcw_home> try all three? and see if they all work equally well
[17:06:33] <pcw_home> maybe you healed it ;-)
[17:06:38] <raynerd> lol
[17:06:56] <archivist> and "big diodes" means little, look at your manual/circuit
[17:07:38] <raynerd> btw, I`ve noticed this before, when the motor starts running, the current drops massively.
[17:08:12] <raynerd> so like same motor in x axis, same results as above, 12.5v about 1.2A but drops to 0.2A when running!
[17:09:03] <pcw_home> Yes because at 12V you cannto supply full motor current when the motor is running at any decent speed
[17:09:11] <raynerd> AH OK.
[17:09:14] <raynerd> I see sorry.
[17:09:27] <raynerd> Well now i`m confused. Same results with the same motor on all three axis!
[17:09:53] <archivist> you need a beefy supply for motors
[17:10:06] <pcw_home> if you run the motors slowly the current should not drop so much
[17:10:23] <archivist> sum your required motor currents
[17:10:44] <raynerd> sum them?

[17:11:11] <raynerd> ahh I see,
[17:11:22] <raynerd> so really I need a minimum 6A supply
[17:11:30] <archivist> bingo
[17:11:38] <raynerd> this is 5A

Tom_itx [Tom_itx!~Tl@unaffiliated/toml/x-013812] has joined #linuxcnc
[17:12:17] <archivist> set your current to 1.5A per motor then
[17:13:59] <raynerd> motors are only 5v 1A so why they pulling 2A ?
[17:14:37] <archivist> see your settings on the chips
[17:15:11] <raynerd> The driver has 2 dip switches and the current isn`t stated, it just says: 100%, 75%, 50 or 25%
[17:15:36] <raynerd> #i`m currently set to 50%
[17:16:53] <archivist> see manual or tb6560 datasheet
[17:17:27] <raynerd> I`m reading the manual?
[17:17:50] <raynerd> I don`t see what the % is of?
[17:20:25] <archivist> data sheet says torque setting(current) try 25%
[17:22:18] <raynerd> humm, OK so with them set to 25%, the OLD 12v 5A supply is working!
[17:23:59] <archivist> just an under rated psu was the problem or running too much current for your motors

[20:49:35] <Tecan> need help connecting this biznatch
[21:00:11] <jdhnc> don't cut the blue wire.
[21:00:53] <djdelorie> <abyss>they're all green!</abyss>
[21:01:38] <djdelorie> If you're a wire-color-nazi, please don't look at my wiring... I use scrap ribbon cable so there are rainbow colors all over the place...

isssy has quit [Quit: Bye Bye]
[21:03:43] <jdhnc> mine tend to be whatever I have closest that is about the right size.
[21:06:07] <djdelorie> well, if we wanted pretty, we'd buy professionally-made equipment, right? ;-)
[21:06:44] <jdhnc> maybe. I'm just frugal/cheap
[21:07:10] <jdhnc> but, some people don't even want to pay money for a compiler.
[21:08:14] <Thetawaves> pay money for a compiler? are you kidding me?
[21:08:25] <Thetawaves> the best compilers are free anyway
[21:09:34] <djdelorie> I write my own compilers :-)
[21:10:09] <jdhnc> I recall.
[21:17:51] <jdhnc> I bought a copy of borland C 4.5, it was disappointing.
