Back
[00:00:07] <JT-Shop> the GS2 manual in the back has the part number for the filter
[00:00:15] <FloppyDisk> ahhhh, I'll check it out.
[00:00:47] <FloppyDisk> I found this inexpensive filter I have considered buying from ebay: http://www.ebay.com/itm/111833137431
[00:00:56] * JT-Shop hopes micges fixes the 2.7 errors by the time the filter arrives
[00:01:21] <Tom_itx> he's pretty good about that
[00:01:46] <JT-Shop> yep
[00:02:07] <FloppyDisk> JT-shop. Sorry for next qeustion, but what are the ferrites for? the output of the vfd to the motor?
[00:02:34] <JT-Shop> yes
[00:02:50] <FloppyDisk> And, they're also in the back of the manual?
[00:02:51] <JT-Shop> 4 wraps of each leg as close to VFD as you can
[00:02:56] <JT-Shop> yea
[00:03:10] <FloppyDisk> got -it... I don't think I have that much wire !! ahhh...
[00:03:45] <andypugh> FloppyDisk: Search for Rasmi Filter and you will find many more inexpensive filters.
[00:04:39] <andypugh> But check leakage current to earth if you have an RCD (ELCB) in the circuit.
[00:04:54] <JT-Shop> we went to Hardy Ar Saturday and an English chap has a fish and chips place in rural AR and drives an antique Mini
[00:05:31] <andypugh> pcw_home: Does the new software say “This message will not repeat” millions of times?
[00:06:31] <Tom_itx> knew a guy here with an old mini
[00:06:37] <Tom_itx> always ran hot
[00:07:08] <JT-Shop> http://gnipsel.com/images/misc/Mini01.jpg
[00:07:10] <andypugh> Not a typical problem
[00:07:15] <JT-Shop> http://gnipsel.com/images/misc/Mini02.jpg
[00:07:37] <Tom_itx> yup, same as only his was green
[00:07:49] <andypugh> That’s a moderately modern one :-)
[00:07:51] <Tom_itx> andypugh, he'd 'souped' his up a bit
[00:08:06] <Tom_itx> also had a jensen healey
[00:08:12] <Tom_itx> definite pos
[00:08:14] <JT-Shop> what vintage is a Mini 1000
[00:08:35] <JT-Shop> my neighbor had a bug eyed sprite
[00:08:51] <Jymmm> JT-Shop: Circa 2016 ;)
[00:08:52] <Tom_itx> used to work on those years back
[00:09:07] <Tom_itx> all the mg mgbgt sprite spitfire etc
[00:09:18] <Tom_itx> mg midget
[00:09:43] <Tom_itx> 70's era
[00:10:01] <FloppyDisk> andypugh - @andypugh - thank you, will do... the ebay one I found was from that - I think??
[00:10:02] <andypugh> Mini 1000 is no older than Mk2 (1967)
[00:10:12] <gregcnc> does every installation of 7i77 and 2.7 have this error issue? I'm about to start working with 7i77, it arrived today.
[00:10:25] <Tom_itx> probably so
[00:10:41] <andypugh> I restored one of these once, a Mini with a boot, (Wolseley Hornet): https://en.wikipedia.org/wiki/Mini#/media/File:Wolseley_Hornet_Biggleswade.JPG
[00:10:51] <Tom_itx> gregcnc, a fix hasn't been written yet
[00:11:05] <Tom_itx> likely won't take long though
[00:11:16] <andypugh> It is a geniuine problem that is being detected, but it is being over-detected
[00:11:34] <PCW> gregcnc: yeah so only if you have a noise issue
[00:11:47] -!- rob_h has quit [Ping timeout: 260 seconds]
[00:11:53] <andypugh> And I am running sserial and _not_ seeing this problem on any of my machines.
[00:12:21] <Tom_itx> andypugh, are you filtering your power?
[00:12:28] <andypugh> Yes
[00:12:50] <Jymmm> Has anyone used a FLIR or SEEK by chance?
[00:12:53] <gregcnc> OK, I'll just go ahead and see what happens. It will likely be several days before I attempt to move an axis.
[00:13:03] <andypugh> Hmm, actually, only the one built-in to the VFD on the mill.
[00:13:19] -!- xrr has quit [Read error: Connection reset by peer]
[00:14:05] <PCW> basically it means there's enough HF ground current flowing down the DB 25 cable
[00:14:06] <PCW> that you generate a a TTL threshold worth of drop ( ~1.4V ) along the cable
[00:14:14] <toastydeath> Jymmm, i have used a FLIR camera
[00:14:23] <toastydeath> or a few, rather
[00:14:26] -!- xrr [xrr!~quassel@c21-76.uvn.zone.eu] has joined #linuxcnc
[00:14:28] <Jymmm> toastydeath: How did you like it?
[00:14:47] <toastydeath> really, really nice for a lot of things, actually. i wasn't expecting it at all
[00:15:14] <Jymmm> toastydeath: have you used any others (for comparison) ?
[00:15:32] <Tom_itx> Jymmm they offer a course here using them for machine inspection
[00:15:35] <Tom_itx> bearings etc
[00:15:37] <toastydeath> I have used a few diffrent ones in passing, there is a particular model of FLIR i have on my wishlist that eevblog has a good review on
[00:15:48] <Tom_itx> for preventative maintenance
[00:15:51] <JT-Shop> I actually probed a clothes pin
[00:16:00] <toastydeath> unfortunately my own experience isn't super useful to me since most of them were way out of my price range personally
[00:16:04] <Jymmm> toastydeath: I'll check it out (eevlog)
[00:16:09] <Jymmm> Tom_itx: Nice
[00:16:38] <Tom_itx> nobody seemed interested in the course but the guy made big bucks walking around taking pics with his camera
[00:16:48] <PCW> if i set error inc to 0 and error dec to 1, I still get multiple messeges that the sserial port will be shut down and that the error messages will not repeat
[00:16:55] <Jymmm> Tom_itx: big bucks?
[00:17:06] <toastydeath> Jymmm, i was not expecting it but they're super fast to check if a bunch of things are working correctly
[00:17:16] <Tom_itx> driving to jobsites inspecting equipment
[00:17:18] <toastydeath> from debugging circuit boards to AC systems
[00:17:22] <Jymmm> Tom_itx: ah
[00:17:30] <Tom_itx> 100k+
[00:17:35] <Jymmm> Tom_itx: DAMN!
[00:17:46] <Jymmm> Tom_itx: Just to say "this is too hot" ?
[00:17:55] <Tom_itx> pretty much
[00:18:05] <toastydeath> the expensive ones have really good dynamic range, high resolution, and are very accurate
[00:18:06] * Jymmm can do that!
[00:18:10] <Tom_itx> think how much it could save a company over a major failure
[00:18:34] <Tom_itx> there were other testing methods taught too but that was mainstream
[00:18:47] <toastydeath> the 400-500 dollar ones are usually in the 400x300 pixel range rather than a full 4000x3000 or whatever
[00:18:51] <Jymmm> toastydeath: Yeah, I have an IR Gun, and I had to justify buying it at the time, but now it's like I use it for everything.
[00:19:02] * JT-Shop thinks a little Dave Brubeck is in order
[00:19:26] <toastydeath> i feel like the ir guns are not quite as useful because you can actually *see* when you're getting a bad reading
[00:19:33] <toastydeath> with a FLIR/similar
[00:19:37] <andypugh> I have now squared-up one casting. Looks pretty good: https://picasaweb.google.com/108164504656404380542/Holbrook#6230894969904273346
[00:19:44] <Jymmm> Tom_itx: Yeah, makes sense.
[00:19:55] <toastydeath> like measuring a cold mirror - you'll see the thermal image in the mirror and not the glow of the mirror itself
[00:20:03] <JT-Shop> andypugh: looking good
[00:20:05] <Jymmm> toastydeath: Oh sure, but baby steps thermal anything started adding up =)
[00:20:08] <toastydeath> whereas you're not always sure with the IR gun if it's the blackbody temp
[00:20:13] <toastydeath> haha
[00:20:15] <Tom_itx> i could drive around the countryside in my eco 'smartcar' taking pics all day for that...
[00:20:50] <Jymmm> Tom_itx: $40, $400, THAN to the fancy $40,000 shit =)
[00:20:54] <Jymmm> THEN*
[00:21:00] <andypugh> The hard part is yet to come, I need to face off an internal web, and bore bearing housings now.
[00:21:01] <Jymmm> err toastydeath
[00:21:18] <toastydeath> Jymmm, it could happen!
[00:21:21] <Tom_itx> andypugh, got the setup figured out for it?
[00:21:27] <toastydeath> i scored a great oscolloscope on ebay for 250 recently
[00:21:33] <Jymmm> toastydeath: Ye, and on a drone too =)
[00:21:36] <toastydeath> you never know when someone else has no idea what they're selling
[00:21:44] -!- tobias47n9e_ has quit [Ping timeout: 255 seconds]
[00:22:05] <andypugh> Tom_itx: Not really. It’s hard to get far enough away to get tools with enough reach in. As you can see, the mill is a bit undesize for the job.
[00:22:18] <Tom_itx> yup
[00:22:27] <Jymmm> toastydeath: "For $99 I'll show you where your home is lekaing hundreds of collars in heating and cooling every year..."
[00:22:42] <andypugh> Without that horizontal spindle I would stand no chance.
[00:22:55] <andypugh> But that spindle really shifts metal.,
[00:23:07] <Tom_itx> gear driven?
[00:23:12] <Tom_itx> i bet it's a hog
[00:23:27] <andypugh> Yes. In fact bottom speed is 45 rpm and it’s a 2HP motor
[00:23:44] <Jymmm> toastydeath: Just setup drone to do google maps, I never have to leave the house, all automated =)
[00:23:49] <toastydeath> hahahaha
[00:23:52] <andypugh> I was running at 200 rpm output and 3000 motor rpm
[00:23:54] <toastydeath> that's actually a brilliant idea
[00:23:56] <Tom_itx> bad things happen in slo mo at that speed
[00:24:06] <toastydeath> i really hope you try that
[00:24:30] <Jymmm> toastydeath: When I get a therm cam and a drone, sure =
[00:24:50] <Tom_itx> Jymmm better get one before faa makes you register
[00:24:55] <gregcnc> guys use them on drones for hog hunting
[00:25:01] <andypugh> Tom_itx: I did find a use for super-low speed: https://www.youtube.com/watch?v=thtDRjgbxRE

[00:25:54] <Tom_itx> what was the spring for?
[00:27:47] <andypugh> Motorcycle seat spring: https://picasaweb.google.com/108164504656404380542/NerACar#6058937721486264610
[00:28:28] <Tom_itx> i kinda new it had to be for the ner-a-car
[00:29:48] <Tom_itx> i've wound springs on the drillpress but much smaller wire
[00:33:21] <andypugh> Yeah, that was 1/4” wire, and there was no way to even open the coil out by hand.
[00:36:30] <enleth> andypugh: great trick, thanks for sharing
[00:38:30] <Tom_itx> i didn't use a roller on the small wire, just fed it by hand

[00:42:58] <Tom_itx> i think andypugh is secretly opening a ner-a-car factory
[00:44:03] <zeeshan-lab> :D
[00:44:05] <Tom_itx> andypugh, do you drive it much?
[00:44:24] <Tom_itx> curious what sort of mileage it gets compared to today's transportation
[00:45:42] <zeeshan-lab> way more than the rx7 i bet!
[00:48:52] <andypugh> It doesn’t get much use, it’s really a bit too slow.
[00:49:22] <zeeshan-lab> could you walk faster?
[00:50:17] <Tom_itx> fun to ride though i bet
[00:50:22] <Tom_itx> gets lots of looks..
[00:52:19] <andypugh> Cannonball Baker did a coast-to-coast on one back in the day and got something like 80 mpg

[01:09:34] <zeeshan-lab> ahaha
[01:09:52] <malcom2073_> I did 172 miles on 15 gallons the other day
[01:10:24] <zeeshan-lab> 6.5 mpg
[01:10:27] <zeeshan-lab> for me
[01:10:45] <malcom2073_> My camaro probably gets about that
[01:11:02] <malcom2073_> The problem with a ner-a-car, is that you'd be run over in america most of the time
[01:11:05] <zeeshan-lab> 140 miles for 21 gallons
[01:11:06] <zeeshan-lab> :P
[01:11:25] <malcom2073_> Lol wtf do you drive?
[01:11:41] <zeeshan-lab> thats not my daily car, thank god.
[01:11:46] <zeeshan-lab> the twin turbo rx7 with the v8
[01:12:14] <malcom2073_> lol
[01:12:17] <Tom_itx> my bud's car got ~20gal/mi
[01:12:18] <malcom2073_> Yeah that'll do that
[01:12:29] <malcom2073_> Tom_itx: Funny car? :)
[01:12:30] <zeeshan-lab> 20 gallons per mile?!?!
[01:12:31] <zeeshan-lab> lol
[01:12:33] <zeeshan-lab> nice
[01:12:34] <Tom_itx> yup
[01:12:34] <malcom2073_> Buddy of mine has an alcohol funny car, gets about that
[01:12:38] <zeeshan-lab> nice

[01:13:50] <Tom_itx> i doubt it could pump that much that quick
[01:13:59] <malcom2073_> It has one operating condition: WOT at redline
[01:14:27] <zeeshan-lab> just changing to fuel injectors
[01:14:33] <zeeshan-lab> at high pressure leads to better atomization
[01:14:42] <zeeshan-lab> more powaah
[01:15:00] <zeeshan-lab> but i think youre right
[01:15:07] <zeeshan-lab> if efi had benefits, youd see it more in nhra

[01:22:35] <malcom2073_> Hah nice
[01:22:47] <zeeshan-lab> lots of heating issues and eddy current to worry about
[01:23:12] <zeeshan-lab> thats kind of why the whole rear door is louvered

[02:08:53] <zeeshan-lab> its hard enough to do the control on a rocket landing on a solid land
[02:08:57] <zeeshan-lab> on solid land!
[02:10:03] <renesis> they had to because elon talked shit and looked dumb
[02:10:26] <renesis> he said boeings landing looked like a crash, wasnt pretty
[02:10:44] <renesis> like, bitch their shit looked like a crash, your shit was a crash
[02:11:54] <zeeshan-lab> renesis what have you crashed
[02:12:06] <zeeshan-lab> big guy
[02:12:08] <zeeshan-lab> :D
[02:12:20] <renesis> context?
[02:12:27] <renesis> not much above 5mph
[02:12:37] <gregcnc> a few endmills a couple axis and several rc planes
[02:12:52] <zeeshan-lab> ill follow what elon musk has to say then :)
[02:12:56] <zeeshan-lab> lol greg
[02:12:58] <renesis> yeah was going to say, theres a 3/8" dimple on my mills table
[02:14:19] <renesis> and no one is keeping you from following elon musk saying his crashes are better
[02:14:54] <FloppyDisk> Anyone have a suggestion where to get an m4 tap? dn't have to be cheap. my existing one 'galls' on the starting threads.
[02:14:55] <malcom2073_> I've crashed a 10 ton robotic vehicle
[02:14:59] <FloppyDisk> it's a cheap HF set.
[02:15:24] <renesis> home depot or lowes should have them
[02:16:06] <gregcnc> what are you tapping?
[02:16:09] <renesis> they will usually sell starting/standard/bottom tap sets, or a standard tap + drill
[02:16:32] <FloppyDisk> aluminum... general purpose, mostly aluminum
[02:16:39] <zeeshan-lab> floppydisk buy some osg taps
[02:16:46] <zeeshan-lab> and never look back to hardware store taps again
[02:16:47] <zeeshan-lab> :P

[02:16:50] <FloppyDisk> What's an OSG tap? Sorry...
[02:16:53] <zeeshan-lab> company
[02:17:19] <gregcnc> real taps are nice, I like OSG form taps.
[02:17:19] <zeeshan-lab> and for small threads like that in aluminum
[02:17:21] <FloppyDisk> got it... I had the HF set, but it's probably not great quality and I use the m4 (m5 and M6) alot...
[02:17:25] <zeeshan-lab> id look into form taps
[02:17:28] <FloppyDisk> Well, did, use it some.
[02:18:06] <FloppyDisk> Cool - Thanks. That why I asked! Otherwise it's Mcmaster, but they're usually pricy on things like that.
[02:19:03] <archivist> best not skimping on taps, machine taps are nicer than hand taps

[02:19:45] <zeeshan-lab> oh nm
[02:19:46] <zeeshan-lab> its lot of 2
[02:19:47] <zeeshan-lab> scam!
[02:19:57] <gregcnc> FYI form taps use a different drill size.
[02:20:17] <FloppyDisk> Good to know on the drill size.
[02:21:37] <FloppyDisk> A dumb question... Would I not use a hand tap to rigid tap?
[02:21:55] <FloppyDisk> I don't have rigid tapping going yet, but I have an encoder and some 3d printed parts to put on my spindle
[02:22:00] <FloppyDisk> and want to try it:-)
[02:22:20] <zeeshan-lab> you can use a hand tap to rigid tap
[02:22:28] <FloppyDisk> Ok. good.
[02:22:29] <zeeshan-lab> but problem is it jams up with chips easy
[02:22:42] <zeeshan-lab> thats why you see spiral flute or spiral point taps being used
[02:22:51] <zeeshan-lab> for blind / thru hole respectively
[02:22:57] <FloppyDisk> I did read that flute count matters (or spiral) so that you don't jam.
[02:23:07] <FloppyDisk> Just hadn't looked into it too much.
[02:23:16] <zeeshan-lab> spiral flute directs the chips outside of the hole
[02:23:21] <zeeshan-lab> spiral point directs it in front
[02:23:29] <zeeshan-lab> hand taps seem to be random
[02:23:36] <archivist> the spirals cut easier than hand taps
[02:23:48] <gregcnc> form tap = no chips
[02:24:02] <archivist> form = more force needed
[02:24:10] <zeeshan-lab> form = best threads!
[02:24:19] <gregcnc> form taps are stronger
[02:24:57] <FloppyDisk> do you hand 'form' or is that rigid tapping only?
[02:24:59] <gregcnc> but if you break on in a hole, seems like ti would be tough to remove
[02:25:26] <gregcnc> I've never tried, but read that people use form taps by hand

[02:25:37] <zeeshan-lab> i have
[02:25:37] <duc> Evening
[02:25:42] <zeeshan-lab> even spiral flute by hand
[02:25:56] <duc> Quick question that I have forgot the answer to
[02:26:00] <FloppyDisk> Never heard of anyone doing that (form by hand).
[02:26:09] <gregcnc> spiral flute taps are bendy
[02:26:14] <duc> Does linuxcnc like speed or position more
[02:26:23] <duc> For servo driving
[02:26:40] <archivist> like?
[02:27:41] <archivist> you setup linuxcnc to use servos how you like
[02:28:16] <duc> I found the answer. Velocity is the easiest according to the forum
[02:28:20] <FloppyDisk> @duc - not sure, but I would think that the servo loop would try to correct both and your PID tuning would be a factor.
[02:29:37] <duc> I can wire the servopack as velocity, position or torque mode
[02:30:24] <FloppyDisk> I think w/ lcnc you can do it how you want and tune accordingly.
[02:30:35] <FloppyDisk> Which is the tricky part...
[02:31:07] <FloppyDisk> I have a mesa 5i25/7i77 w/ west amp servo's and it's a funny deal, but the drive closes the velocity loop.
[02:31:19] <FloppyDisk> I wouldn't normally setup a system that way, but it will work.
[02:32:30] <duc> So you just issue steps and direction to it?
[02:33:10] <FloppyDisk> do I? No, that would have the drive close the position loop.
[02:33:29] <FloppyDisk> What are you trying to do? and what hardware do you have?
[02:34:10] <duc> Yaskawa drives with 5i25/7i77. I'll have lcnc close the loop on mone
[02:34:12] <duc> Mine
[02:34:36] <FloppyDisk> I think w/ yaskawa you can choose, depending on the servo drive.
[02:35:01] <FloppyDisk> In japan, theyu're huge fans (for whatever reason) of the servo driving closing the position loop and sending step/dir.
[02:35:04] <duc> Picked up the analog drive units
[02:35:10] <FloppyDisk> ahhh..
[02:35:12] <Contract_Pilot> So on my lathe thinking 7I77 with servo's?
[02:35:25] <Contract_Pilot> Servo for the spindle?
[02:35:39] <FloppyDisk> So, you can set the drive in torque or velocity mode and then tune w/ lcnc...
[02:36:05] <FloppyDisk> I don't really know all the details, but used JT-shop (john thornton's)instructions to tune that way...
[02:36:41] <FloppyDisk> I had to follow his instructinos w/ the old west amp drives from the anilam control.
[02:36:57] <FloppyDisk> @contrac_pilot - sounds good to me, I like servo's.
[02:37:01] <archivist> Contract_Pilot, for normal turning/screw cutting, normal motor drive is ok
[02:37:18] <FloppyDisk> You can go servo w/ spindle, but you need a large motor depending on the size of the lathe...
[02:37:28] <FloppyDisk> That can be $$$...
[02:37:30] <Contract_Pilot> Yea, bit would love to use the spindle for indexing as well.
[02:37:32] <archivist> encoder on the spindle for screw cutting
[02:37:48] <FloppyDisk> You can also go w/ vfd, 3ph motor, and encoder.
[02:37:55] <archivist> indexing is where the servo is needed
[02:38:06] <FloppyDisk> Oh - for indexing then servo!
[02:38:13] <Contract_Pilot> I have a 3ph motor with a hitichi vfd already
[02:38:48] <archivist> vfd does make the best servo though
[02:39:39] <Contract_Pilot> Want to make use of this 7I77
[02:40:08] <Contract_Pilot> Unless somone wants to trade out with me on 2 7I76's i can put in som cash
[02:43:59] <Contract_Pilot> Somone Jacked MY VHF Antenna...
[02:44:24] <gregcnc> I have 7i76 i was going to use on my lathe but got a 7i77. I decided to try closed loop on this one. Servos will be torque mode because they don't have tachs.

[07:32:59] <archivist> Jymmm, what type of boiler
[07:34:22] <archivist> domestic, traction engine,power station
[07:34:28] <archivist> nuclear
[07:34:28] <Jymmm> archivist: Fundamentals basically, like for a radiator heating system. (I'm still on the kick of a "packable" hot water generator)
[07:34:59] <Jymmm> archivist: electricity generator that is
[07:35:33] <archivist> stop dreaming, damned silly
[07:36:08] <archivist> the basics, most efficiency needs very high pressures and temperatures

[07:36:18] <archivist> booooom

[07:37:33] <Jymmm> I already have a small oil cooler to use as well

[07:38:37] <archivist> read up on flash boilers
[07:38:55] <archivist> no the main issue is pressure
[07:39:32] <archivist> steam loco was only about 5% efficient
[07:40:10] <archivist> a power station with all the economics condensation etc manages around 30%
[07:40:11] <Jymmm> per BTU of coal/wood?
[07:40:26] <archivist> yes
[07:41:25] <Jymmm> Ok. In this case, the fire already exists. either it also generates some/any electricity or it doesn't. so not a big issue
[07:42:35] <archivist> leaning a boiler against a small fire will get enough to light an led possibly
[07:43:07] <archivist> far less effort to carry a battery
[07:44:19] <Jymmm> The battery is dead and needs to be recharged and it's winter .
[07:44:25] <Jymmm> archivist: https://www.youtube.com/watch?v=nAORPy4J6j8
[07:44:48] <archivist> you should be carrying enough batteries!
[07:45:01] <Jymmm> archivist: Like that, but a coil shoved into the coals of a campfire
[07:45:34] <archivist> that is a version of a flash boiler
[07:46:14] <archivist> but the pressure needs a pump into the coil
[07:46:30] <Jymmm> check valve
[07:46:34] <archivist> that is a plain heater
[07:46:41] <archivist> no real pressure
[07:47:00] <Jymmm> Ever take apart a coffee maker?
[07:47:09] <archivist> you need to work against the pressure the engine needs
[07:48:08] <archivist> I see you dont realise the problem of continuous water supply to the coil under pressure at the rate it is converted to steam for the engine
[07:48:26] <archivist> look how a steam car works

[08:17:46] <MattoMatic> so, there's no point suggesting a fly cutter to someone with a chinese spindle that won't go lower than 2krpm reliably?
[08:18:38] <archivist> you need some grunt for slow speed flycutting cast iron
[08:19:40] <MattoMatic> arr. AFAICS, you need to gear those motors down, so there's no point paying for the 4 bearings and the collet chuck
[08:20:01] <MattoMatic> do the pulleys and spindle first, worry about VFD later

[14:52:11] <lair82> Good Morning guys, has anyone tried to use G43.1 ?
[14:54:34] <cradek> having a problem?
[14:55:10] -!- sumpfralle has quit [Ping timeout: 265 seconds]
[14:56:03] <cradek> hm I think the docs for g43.1 are totally wrong
[14:58:03] <lair82> Well, not sure really, we tried it yesterday, and it doesn't appear to do what it says it is supposed to, or maybe it does and it isn't making sense to us.
[14:58:28] <cradek> what are you trying to do?
[14:59:52] <lair82> if you do a G43.1 Z 0.250 is it supposed to add/subtract that from the current loaded tool data, or does it disregard the tool table data and only use what you give it with the command?
[15:00:51] <cradek> g43.2 adds the given values to the existing offset. g43.1 replaces the tool offset with the given values. the g43.1 docs are wrong.
[15:01:20] <lair82> We were a little afraid of it after we saw the relative z position changing as much as it did when we issue this command from MDI, Ahhh, this makes sense then
[15:01:39] <cradek> looks like maybe you want http://www.linuxcnc.org/docs/html/gcode/g-code.html#gcode:g43.2
[15:02:31] <lair82> we have been using your g43.2, and it is working as intended, but we figured we would give g43.1 a whirl, and realized real quick that was not what we were expecting
[15:02:48] <JT-Shop> rut row
[15:03:26] <cradek> hi, JT-Shop :-)
[15:04:42] <JT-Shop> offsetting should be replacing
[15:07:49] <cradek> while you're in there, it might be nice to explicitly say that neither g43.1 nor g43.2 changes the tool table
[15:08:01] <cradek> well I guess no g43* command does, so maybe it's not necessary to state
[15:08:18] <cradek> thanks for fixing
[15:08:31] <JT-Shop> yea that's a good idea to say that

[18:50:45] <archivist> JT-Shop, now Im back home, you can use your scope A+B /A-B to see what is induced on a particular wire chan 1 at one end, chan 2 at the other
[18:51:34] <archivist> this is in the presence of any noise in the scope ground
[18:52:15] <archivist> methinks waiting for a filter is best

[19:27:37] <TAPit> Also - yesterday there was discussion of difference between touch off to tool fixture and touch off to workpiece - did you arrive at a conclusion - touch off to Workpice worked as it was expected to for us while fixture did NOT work as expected.
[19:29:22] <rob_h> well finaly got the machine delivered today and sat into place... now to give it a little clean , put some guards back and hook it up and get it dirty :) http://imagebin.ca/v/2QrGOM0R8tVP
[19:29:32] <rob_h> http://imagebin.ca/v/2QrG007TZBTL
[19:31:09] <cradek> TAPit: I am pretty sure they both work right. if you could tell us more about how your expectations were not met maybe we could offer some advice.
[19:33:25] <TAPit> cradek: I had Touch Off To Fixture set - touched off to the bed of the machine - the X axis, of all things, was off the left hand side of the bed by about 1 foot. I gave up - the cnc operator played with for about a hour using Fixture - and it works as they expect it to. I can ask the cnc operator to try the other but at this point - it is working as they want it to. So I am unsure of what else to add. :)
[19:34:18] <cradek> on a mill it would be very unusual to have an X offset in the tool table at all
[19:34:38] -!- sumpfralle [sumpfralle!~lars@erina.opennet-initiative.de] has joined #linuxcnc
[19:34:47] <cradek> maybe on a dual spindle machine, or a probe or camera mounted off to the side of the main spindle
[19:36:07] <cradek> it's hard from this information to guess with 100% certainty what you were doing wrong, but if you touched off a *tool* in X that would surely be a wrong thing to do
[19:36:24] <cradek> (on a lathe you would definitely want to do that sometimes)
[19:36:38] <lair82> Hey Guys, here is what we are setting up now, second job on the machine, there are mounting holes that need to be perpendicular to the taper, around the taper, so mounted the A axis to the corresponding angle. http://postimg.org/image/veju7c3t1/
