[17:23:04] <bdale> skunkworks: btw, I've got solid-seeming 3-axis motion control now .. as soon as I can get a couple "day job" things done, I'm nearly ready to re-install the head.
[17:23:37] <skunkworks> bdale: great!
[17:24:45] <bdale> only remaining "funny" with the wiring is that if I introduce about 6" of unshielded ribbon cable between the pluto-p and the wall of my nema box, I get following errors. if I leave that out and run the shielded, high-quality 25-pin D-shell cable all the way to the pluto-p, all works great. so I've got rethink how I get the cable from the PC to the pluto-p.
[17:24:46] <skunkworks> bdale: did you see the weekend progress? http://www.youtube.com/watch?v=2E3PMooch1k
[17:25:07] <bdale> yes, I looked at that .. way cool!

[17:26:40] <Jymmm> Binary day!
[17:26:47] <bdale> I doubt the extra cable length is at at fault, though it could be .. seems more likely to me that I'm picking up noise.
[17:27:54] <pcw_home> 1B
[17:28:12] <bdale> cutting a hole in the box wall and using a split cover plate with a grommet for the cable may be a good solution .. I'll worry about it later, though, too much else I need to do today to keep getting $$

[18:20:20] <kiyokan> Hello, i just made a mistake and do not have the option to correct it the way it needs to be done. I bought a set of 7/8 lathe tool bits where i needed a set of 1/2. is there any way to still be able to use the 7/8 without having to grind the bottom of them down to 1/2?
[18:20:59] <awallin> get a tool-holder that has vertical adjustment ?
[18:21:35] <SWPadnos> yeah. it seems there are two options (without buying the right tools): modify the tools or modify the holder(s)
[18:21:39] <kiyokan> also here is a pic of my lathe, and you can kinda see its tool post
[18:21:40] <kiyokan> http://www.harborfreight.com/9-inch-x-20-inch-geared-head-belt-driven-bench-lathe-45861.html
[18:22:12] <kbarry> Gotta love HF
[18:22:33] <kiyokan> i do, just wish they sold the stuff they show online in store.
[18:22:44] <awallin> you shouldn't leave the chuck-key like that :) will fly a long way when someone turns on the spindle...
[18:23:28] <kiyokan> yeah i have seen that happen only once was funny to watch the guy lear a hard lesson but he was warned...
[18:23:35] <kiyokan> learn*
[18:26:02] <kiyokan> so grinding them down is the cheapest option, but going to be a pita. i dont think they can be returned how ever i will check to see if they will take them back slightly used... or some how lower the tool post, no idea even how to do that.
[18:29:32] <kiyokan> well just got off the phone they wont take them back...
[18:29:54] <Jymmm> exchange?
[18:30:00] <JT-Work> mill them down
[18:30:01] <Jymmm> are they used?
[18:30:27] <Jymmm> JT-Work: laser engraved ceramic tile (the 2nd one is actually better, but the 1st one shows up more because I rubbed some carbon dust into it) http://i55.tinypic.com/se6pt3.jpg
[18:30:48] <JT-Work> Jymmm: cool
[18:30:53] <kiyokan> for about 30 seconds till i noticed they were to big. but i had tightened them down in the tool post so now one of them has 3 little dents in it.
[18:31:19] <Jymmm> kiyokan: ebay em and buy the right ones
[18:32:14] <kiyokan> yeah just wish i could have somehow been able to use them. was looking forward to using that parting tool.

[18:37:44] <kiyokan> so any one want this set of tool for 35$ shipped? http://www.harborfreight.com/20-piece-metal-working-lathe-tool-kit-43536.html
[18:38:44] <Jymmm> kiyokan: Sure, if they'll fit in a 1/2" =)
[18:39:12] <kiyokan> they fit if you have a nice grinding wheel.
[18:39:29] <Jymmm> nope, no gots
[18:39:32] <kiyokan> i might keep them but my wheel is in very bad shape has some deep groves in it..
[18:40:01] <kiyokan> and dont know how to make it normal again besides running stock into it...
[18:40:58] <kiyokan> oh and i should be using these to start my drilling hole correct? v
[18:41:03] <kiyokan> http://www.harborfreight.com/5-piece-center-drill-countersink-set-with-60-angled-tip-42280.html
[18:41:07] <JT-Work> wow that is old school tooling
[18:41:32] <kiyokan> what is?
[18:41:43] <JT-Work> I bet the T slot cleaner is really useful on a lathe
[18:41:53] <JT-Work> the tools you linked to
[18:42:13] <kiyokan> yeah they are very nice and strong but just 0.375 to big.
[18:42:22] <JT-Work> they used that kind of tooling in the 30's - 50's
[18:42:52] <kiyokan> they should stop selling them so people like me stop getting confused. i cant belive i missed the part where it said 7/8...
[18:44:01] <kiyokan> although i do have a band saw with a72in blade. those are seemly hard to find.
[18:44:33] <JT-Work> bandsawbladesdirect.com
[18:44:54] <kiyokan> that page looks a bit messed up
[18:45:06] <kiyokan> lots of weird symbols.

[18:54:05] <JT-Work> do you know how to sharpen HHS tools?
[18:54:27] <kiyokan> no. and even if i wanted to i need to find out how to fix my grinding wheel
[18:54:48] <JT-Work> then don't buy the HF ones
[18:56:47] <kiyokan> also is there any way to make an acme threaded rod on a lathe?

[23:18:51] <andypugh> I think my Z is too stiff. (still on the Acme screw) though it does move freely downwards. I am trying to decide whether to try a pneumatic counterbalance first, or a ballscrew
[23:21:44] <Valen> we found with our 100kg head that for a servo system it needs to be fairly balanced
[23:21:51] <Valen> otherwise the PID doesn't tune well
[23:22:40] <andypugh> Aye, I was wondering if that would be an issue.
[23:23:31] <andypugh> So I need a long-stroke cylinder then. I have found a promising looking rodless one.
[23:23:37] <Valen> you can use bias to tune it out somewhat
[23:37:29] <andypugh> So, if the whole machine weights 500kg, I reckon 200kg for the knee?
