[00:00:03] <JT-Shop> always a good plan
[00:00:12] <L84Supper> intermittent problem or ? you'll see
[00:00:50] <PetefromTn> yeah I guess so...
[00:02:15] <PetefromTn> what are your thoughts on the element I chose. 2500 watt, 240v, and a measured 24 ohms with the wires hooked up to the resistor. I dunno what the rating would be for it in AIR since it is rated for 25oo watts in water.
[00:02:51] <Connor2> Allot less..
[00:02:52] -!- Nick001-Shop has quit [Remote host closed the connection]
[00:02:59] Connor2 is now known as Connor
[00:03:27] <PetefromTn> yeah but WHAT?
[00:03:36] <Connor> No clue. :)
[00:03:37] <L84Supper> 10:1 in air so maybe 250W
[00:03:56] <PetefromTn> REALLY well we set that number to 300 in the setting...
[00:04:35] <PetefromTn> again funny thing is I never actually moved the head so the drive should have never sent any power to the resistor yet. I just energized the servos...
[00:04:48] <JT-Shop> water heater elements don't like to be in the air when they get hot, but how long would the breaking resistor be powered up a second or two
[00:05:00] <PetefromTn> if that...
[00:05:42] <PetefromTn> I have one on my 7.5HP spindle motor which is 5.5kw and it is about the same size resistor incidentally and it works fine and honestly does not even get that hot really...
[00:05:43] <JT-Shop> I had to put one on my GS2 VFD to get the spindle to stop quick for tapping
[00:06:02] <PetefromTn> yeah me too...
[00:06:20] <PetefromTn> nice that they are only $10.00
[00:08:08] <L84Supper> 0.6 vs 0.025 W/(m·K)) air vs water 24:1 but that's comparing the heat absorption
[00:08:12] <JT-Shop> aye, that does help when sperimenting
[00:08:16] <Connor> 600 Watts
[00:08:25] <Connor> Water makes no difference...
[00:08:38] <Connor> are the drives 120 or 240 v ?
[00:08:41] <L84Supper> the 2400W is just the rating of 240V with a 24 ohm load
[00:08:45] -!- abrookins has quit [Ping timeout: 256 seconds]
[00:08:48] <cpresser_> PetefromTn: where do you get 10$ resistors?
[00:08:57] <Connor> yea 600W at 120v
[00:14:25] <Tom_itx> is a stovetop element similar resistance?
[00:14:29] <Tom_itx> they work fine in free air
[00:14:54] <Connor> Hot water heater element will be fine.. it's not like they're ran continues duty..
[00:15:00] <Connor> in this application.
[00:15:04] <L84Supper> PetefromTn: whats the 300 setting all about?
[00:15:15] <L84Supper> a wattage setting?
[00:15:39] <Connor> If that's the Watts setting... then.. you need to set it for the rated element.. makes no difference if it's in air or water.
[00:16:22] <L84Supper> the current is still determined by the voltage generated by the motor and the resistance
[00:17:30] <r00t4rd3d> resistance is futile
[00:17:57] <r00t4rd3d> join the force luke
[00:18:50] <L84Supper> should have been the campaign slogan for Bush in 80
[00:19:04] <L84Supper> sorry 2000
[00:19:36] <L84Supper> fits Reagan as well
[00:24:39] <L84Supper> PetefromTn: whats the motor voltage?
[00:24:59] <Connor> I think it's single phase 240v.
[00:25:05] <PetefromTn> Okay just went out there and TRIED it again. Not sure what the hell the difference was other than I set the wattage at 150 in setting CN012 instead of 300. It SEEMS to work properly now. The resistor got hot to the touch like the one on the spindle motor now and I was able to rapid the millhead at twice what I was before. That is all I was able to test thus far.
[00:25:07] -!- erictheise has quit [Quit: erictheise]
[00:25:24] <PetefromTn> The motors are 1kw 240v 3 phase I beleive.
[00:25:44] <PetefromTn> cpresser_: they are simple water heater elements you can buy at any hardware stor.
[00:25:48] <Connor> is that a value for wattage ?
[00:25:48] <PetefromTn> store.
[00:25:57] <PetefromTn> apparently..
[00:26:10] <Connor> well @ 24ohms @ 240v = 2400watts
[00:26:28] <Connor> @ 24ohms @120v = 600watts
[00:26:30] <L84Supper> add fins to the heater element
[00:26:59] <L84Supper> increasing the surface area will increase the thermal conductivity
[00:27:04] <PetefromTn> it is not a problem I have them installed in a small vertical space between the column and the electronics cabinet
[00:27:19] <PetefromTn> besides that would be easier said than done really.
[00:27:59] <L84Supper> use a contactless IR thermometer and read the the temp when braking
[00:28:06] <PetefromTn> right now unless I run into that damn clicking again it accomplished the objective. Before If I rapided it at anything more than about 70 IPM it would fault, now I just tested it at 120 and it was working...
[00:28:17] <PetefromTn> Got one I can borrow LOL
[00:28:24] <Connor> I Do.
[00:28:36] <PetefromTn> how did I know that was coming LOL...
[00:28:41] <Connor> ROFL
[00:29:02] <PetefromTn> Oh by the way I thought about that paint, you have been so helpful to me you are welcome to use it as much as you need for free...

[00:29:30] <PetefromTn> LOL...
[00:29:48] <L84Supper> http://www.harborfreight.com/non-contact-pocket-thermometer-93983.html even cheaper
[00:30:44] <Connor> I have a Ryobi one.. I can't use it in the house.. because the dog hears the BEEP and sees the laser dot and goes nuts wanting to play "Red Bug"
[00:31:19] <Connor> I don't mind playing Red bug with her.. but, she obseses for hours after we're done...
[00:31:24] <PetefromTn> Hmm might have to pick one of those up..
[00:31:44] <PetefromTn> I was gonna use that stuff to paint my Nacra Catamaran sailboat LOL...
[00:31:55] <Connor> http://www.homedepot.com/p/Ryobi-Tek4-Professional-4-Volt-Infrared-Thermometer-RP4030/100671261#.UYrudS7SGtg
[00:32:13] <PetefromTn> Now that it works I am gonna try upping my rapids on the Z and see how far it can go before it faults again...
[00:32:16] <Connor> That's the one I hve
[00:32:33] <Connor> Probably won't at this point..
[00:32:39] <PetefromTn> LOL you likethe spensive ones...
[00:32:55] <PetefromTn> probably won't what?
[00:32:59] <Connor> It wasn't that much when I bought it.. I think it was $40.00
[00:33:03] <Connor> Fault out.
[00:33:13] <PetefromTn> oh that would be nice LOL
[00:33:21] <PetefromTn> one more issue sorted..
[00:33:36] <Connor> Now just the noise generated by the spindle..
[00:33:44] <Connor> Dinner Time.. back in a while.
[00:33:55] <PetefromTn> Got a small 8gb flash drive and gonna try to run some simple code..
[00:33:58] <PetefromTn> enjoy man...

[00:51:30] <PetefromTn> Okay fellas, I was just out there playing with the setup and I changed that parameter for the resistor output wattage to 150 and was able to up the Z axis rapid speed to like 300 easily, when I went t 340 I got another fault so I am gonna up the resistance setting to 250 again and see if I can get it to go faster without faulting.

[00:52:09] * Tom_itx waits for fireworks
[00:52:19] <Valen> see if you can see why its faulting
[00:52:44] <PetefromTn> I know why its faulting...
[01:03:08] <r00t4rd3d> you?
[01:13:07] <PetefromTn> okay I just was able to rapid that massive millhead up and down the column at 475 IPm without any faults... AWESOME!!
[01:13:21] <Connor> Damn, That's fast
[01:13:38] <Connor> Scary fast.
[01:13:54] <generic_nick|2> yay, my old parts mill is gone!
[01:14:11] <generic_nick|2> cherry picker held together long enough to get it on the trailer at least
[01:14:49] <PetefromTn> yeah you should see it in person LOL
[01:16:22] <PetefromTn> about crap yourself speed rofl..
[01:18:19] <PetefromTn> Honestly it SHOULD do 650 like the other two axes but 475 is faster than the stock setup so I'm happy now,,,

[02:14:54] <PetefromTn> OMFG!! I just ran a simple circular interpolation program with the Cincinatti Arrow. I ran it in air several times to ensure it was gonna do what I wanted it to do and after I felt comfortable with it I decided to FINALLY strap a piece of aluminum to the table to see how she cuts.
[02:15:27] -!- jfire has quit [Quit: Leaving.]
[02:16:30] <PetefromTn> I zeroed on a piece of paper and set my Z,X,and Y and held my breath and hit go. It ran a 1/4 inch four flute cutter in .050 DOC passes on a 2" interpolated circle down to half an inch. Flood coolant, spindle on and off, all three axes did exactly what they were supposed to. It was awesome.

[02:17:01] -!- slifty has quit [Quit: Leaving...]
[02:18:19] <L84Supper> PetefromTn: what was causing the fault?
[02:18:21] <PetefromTn> The best part is that once I finished the program I raised the millhead up and not expecting anything super precise on my first cut I put my telescoping gauge in the resultant hole and measured it with my calipers and then my best micrometer. The hole is 2.0001!!! I cannot freakin' believe it. It is also about as round as I can measure. I almost crapped my pants when I measured it ROFL...
[02:19:04] <PetefromTn> The fault as I said was from regen when the millhead goes DOWN the column. The head is rather heavy and it was kinda causing the regen to overcome the built in resistor on the drive.
[02:20:05] <PetefromTn> Once I installed the new water heater element resistor and got it dialed in with the drive it now can rapid at almost 500 IPM down the column without tripping the overvoltage error.

[02:20:57] <PetefromTn> Now all I need to do is work with Mike Kilroy on getting the spindle setup correct and I should be able to start really making parts with this monster. The program ran exactly as I wanted so my Sheetcam post is apparently working fine with EMC.
[02:21:29] <PetefromTn> I do want to modify my post so that at the end of a program the millhead goes up to maxZ and the table centers and comes fully forward.
[02:21:43] <PetefromTn> Other than that it ran perfectly. I am STUNNED!!
[02:21:57] -!- maximilian_h has quit [Ping timeout: 248 seconds]
[02:22:38] <jdh> do you always want it to do that? You could add a pyvcp button to go there, or G28
[02:24:52] <PetefromTn> Honestly I do actually want it to do that after every program because I want to be able to unload and load parts without reaching into the machine to do it or jog it closer to me...
[02:26:05] <Tom_itx> i added that to my post
[02:26:16] <Tom_itx> make sure you put the G28z on a separate line
[02:26:36] <Tom_itx> or you'll end up hitting fixtures
[02:29:37] <PetefromTn> so you do a G28 at the end of the program and it goes to your final home positions which for me would be table in center of X table all the way towards the op in Y and head all the way up in Z...
[02:29:54] <PetefromTn> whatsa G28z?
[02:30:58] <Tom_itx> i do G49 G28 Z0
[02:31:04] <Tom_itx> G28 Y0
[02:31:20] <jdh> you store a position with g28.1 first
[02:31:32] <Tom_itx> well i didn't
[02:31:38] <Tom_itx> i just send it to 0
[02:33:00] -!- fiesh has quit [Read error: Operation timed out]
[02:33:04] <PetefromTn> why Z0? Is that machine coord Z0 perhaps at the top of travel?

[02:34:11] <Tom_itx> but i also use G54 offsets
[02:34:20] <jdh> g28 is absolute
[02:34:23] <PetefromTn> Sheetcam has two parameters for parking and toolchange position. Talking with Art apparently they are both machine coordinates so in theory I could just say go to Z o and whatever y forward is and set those up that way. Should work the same...
[02:34:54] <Tom_itx> they are absolute coordinates yes
[02:34:56] <PetefromTn> I want to use g54 etc for my vises once I get them etc..
[02:35:13] <PetefromTn> damn you should see the finish on this hole...LOL
[02:35:27] <Tom_itx> i set my tool table to match my cad cam tool setup too
[02:36:14] <PetefromTn> actually on my last machine I setup my tool table in mach3 and used no tool offsets in Sheetcam just the tool numbers and descriptions... rather zero..
[02:36:43] <PetefromTn> Would like to do the same with this machine since I will be using a toolchanger eventually on it and getting everything working the way it used to work on the original control.

[02:38:29] <Tom_itx> same town as the fest
[02:38:34] <PetefromTn> ROFL
[02:38:40] <Tom_itx> might swing by for a day or so
[02:38:44] <PetefromTn> lucky guys
[02:39:01] <Tom_itx> i go by there all the time
[02:39:04] <Tom_itx> never been inside
[02:39:12] <PetefromTn> nows your chance...
[02:39:50] <Tom_itx> i've been out of the loop for probably 15-20 yrs for the big machines
[02:39:50] <generic_nick|2> what happens if there is a tornado?
[02:40:00] <Tom_itx> you land in a field nearby
[02:40:19] <generic_nick|2> do we need to wear ruby slippers so we can get back to the fest?
[02:40:26] <PetefromTn> Funny I machined that hole and for some reason which I was not sure of it left a little teet in the middle of the hole like a little stick sticking up. I thought it was a problem but then I looked back at sheetcam and it was that way in the toolpath LOL... I had a setting wrong.
[02:40:43] <PetefromTn> Been awhile since I used the program or ran a CNC on it LOL

[02:44:16] <PetefromTn> Would love to come tho...
[02:44:38] <generic_nick|2> plus if i had the time to travel, i'd be on the rubicon lol
[02:44:42] <Tom_itx> i'd be in the same boat if i didn't live here
[02:45:07] <PetefromTn> I hear ya...
[02:45:13] <generic_nick|2> plus i see my cnc's everyday, the last thing i want to see on vacation is another cnc lol
[02:45:31] <PetefromTn> Damn I am happy that Z axis faulting issue appears to be behind me now.
[02:45:42] <generic_nick|2> was it the drive faulting?
[02:45:57] <PetefromTn> Can't miss mine, it is this HUGE box in the garage LOL...
[02:46:05] <generic_nick|2> or a ferror?
[02:47:11] <PetefromTn> Yeah it has been giving me overvoltage on Z down moves due to the massive millhead weight. I had to switch to the braking resistor from the factory internal one to overcome that overvoltage fault. Honestly I knew that was gonna be the case as Mike Kilroy told me so even before I tried it...
[02:47:13] -!- kmrhb has quit [Ping timeout: 245 seconds]
[02:47:32] <generic_nick|2> gotcha
[02:47:59] <PetefromTn> Now that a larger resistor capacity is there I was rapiding the head down and up the column at like 475 IPM....
[02:48:29] <PetefromTn> I backed it back to 100 for these initial program run tests tho. also set the feedrate override to like ten..
[02:49:47] <Valen> I suggest finding a "torture test"
[02:50:03] <Valen> something that will max out all the axies for 10 minutes or so
[02:50:17] <Valen> lots of accelerations, rapids short little hops
[02:50:24] <Valen> all over the bed if you can
[02:50:53] <Valen> we found ours isn't quite right, tune it in tight in one spot and it'll oscillate in another
[02:51:15] <PetefromTn> that is the plan man... still have LOTS of tuning to do here. just getting started really...
[02:51:40] <Valen> still, pretty good when it all works though ;->

[03:09:59] <PetefromTn> I do believe that I have lost a LOT OF HAIR over it thoo
[03:10:06] <Valen> thats a given
[03:10:08] <jdh> hair is overrted
[03:10:12] <PetefromTn> It has been a real bitch to get it to this point.
[03:10:23] <ssi> still
[03:10:35] <ssi> a lot of people in here would gladly put in the effort and the $2000 :)
[03:10:49] <PetefromTn> If it works and I can use it to make money I will be thousands ahead of what it would cost to buy even a decent working used VMC...
[03:11:16] <Valen> 1
[03:11:24] <Connor> It is a nice machine. I swear, one of these days, I'm going to finish up mine..
[03:11:25] <Valen> this is what $3000 gets you here http://www.ebay.com.au/itm/ROLAND-ENGRAVER-Roland-EGX-20-NEW-IN-BOX-FREE-DELIVERY-NEW-PROTECH-CNC-/251262967648?pt=LH_DefaultDomain_15&hash=item3a80709f60&_uhb=1
[03:11:40] <PetefromTn> Agreed, I can' t complain at all... I love it and if it works the way I hope it will make me some decent cash for my family...
[03:12:19] <ssi> Valen: yea well your dollars are smaller than ours
[03:12:31] <Valen> $au is 1.04 $us
[03:12:34] <ssi> see?
[03:12:36] <ssi> 4% smaller
[03:12:37] <ssi> :D
[03:12:38] <PetefromTn> It has really taken a lot of patience and even more importantly a LOT of good friends helping me or this would have never happened at all...
[03:12:51] <Valen> 1 australian dollar buys you more than one US$

[03:15:20] <Connor> I wish I had a easier way to cut down my alumn stock..

[03:15:29] <ssi> Connor: get a bandsaw!
[03:15:33] <Connor> Breaking out my Chop saw makes a HUGE ass mess.
[03:15:39] <PetefromTn> I want a CNC lathe next..... but that one is too big.
[03:15:43] <ssi> Connor: I bought a grizzly 7x12 bandsaw last year and I'm quite happy with it
[03:15:43] <Connor> ssi: I have one.. Just doesn't do well on Alumn
[03:15:56] <PetefromTn> REALLY mine kicks ass in aluminum...
[03:16:03] <PetefromTn> Gotta buy better blades..
[03:16:12] <ssi> that mazak is super hot, but too big for me
[03:16:32] <Connor> Having issues with it.. stupid pulley comes off... it's just a little table top one..
[03:16:32] <PetefromTn> I get mine from Holston gasses and you need to buy Lennox variable pitch aggressive...

[03:17:20] <Connor> one like that.
[03:17:20] <PetefromTn> I got that 4x6 here but I blew the damn motor on it. Then I got the 7x12....
[03:17:37] <ssi> yeah 4x6 bandsaws are mostly shit
[03:17:40] <PetefromTn> Thats a toy and it is also a wood bandsaw...
[03:17:52] <Connor> Yea, that's my point..
[03:17:59] <Connor> It sucks for trying to do alumn.
[03:18:00] <PetefromTn> Actually I used my 4x6 for years with great success....
[03:18:01] <ssi> haha yea that's not a bandsaw
[03:18:19] <ssi> PetefromTn: I did too, so long as great success implies "one piece of metal came off the other piece of metal"
[03:18:22] <ssi> it wouldn't cut anything like straight
[03:18:25] <PetefromTn> It is no 7x12 tho that thing is much more powerful and has liquid coolant onboard...
[03:18:26] <ssi> or quickly
[03:18:28] <ssi> or cleanly
[03:18:58] <Connor> PetefromTn: You need to come over sometime and look at my tiny a$$ shop.. you'll see what I'm dealing with as far as tools...
[03:18:58] <ssi> it was a $200 HF 4x6 though... about the junkiest bandsaw one can get that's still nicer than Connor's fischer-price saw :D
[03:19:01] <PetefromTn> Hmm Mine cut fine with the right blades and proper adjustment. I recall it was a bitch getting it to cut right...
[03:19:17] <ssi> I moved it to the airport, and one of the castings snapped in half during the journey
[03:19:18] <PetefromTn> ROFL...
[03:19:18] <Valen> push harder ;->
[03:19:29] <PetefromTn> you guys crack me up..
[03:19:31] <Connor> I'm for sure not using the right blades for alumn on it.. not sure what to get.
[03:19:38] <ssi> Connor: get a horizontal bandsaw :P
[03:19:59] <r00t4rd3d> most people have no clue how to tune a band saw.
[03:20:03] <PetefromTn> This 4x6 is not that big really. In fact you can use it on a table top without the stand if you want..
[03:20:19] <Connor> http://www.ivdc.com/cnc/shop/ My shop before getting the Mill.. it's were the Radial Arm saw is.. (and the saw is gone)
[03:20:23] <PetefromTn> I found you gotta make that blade TIGHT!!
[03:20:37] <r00t4rd3d> you shouldnt have to over tighten it
[03:20:40] <PetefromTn> Then play with the guides ad nauseum...
[03:20:51] <PetefromTn> You do on the POS 4x6's
[03:21:00] <r00t4rd3d> look at the blade from the top down, when it flattens out, thats enough
[03:21:02] <PetefromTn> My 7x12 is another animal completely...
[03:22:16] <ssi> you guys see my ridiculous 3000ipm plasma jog test earlier?
[03:22:21] <PetefromTn> Love how that Aus ebay site says G'day instead of hello ROFL...
[03:22:28] <PetefromTn> nope...
[03:22:31] <PetefromTn> do tell...

[03:23:15] <ssi> hahahaha that's the best part
[03:23:17] <ssi> those are just love taps
[03:23:19] <r00t4rd3d> what could you cut at 3000ipm besides paper?
[03:23:24] <ssi> if i really forget and smack it, it's pretty gnarly
[03:23:27] <PetefromTn> AIR.
[03:23:52] <Valen> foam
[03:23:55] <Valen> timber perhaps

[03:24:05] <PetefromTn> Those uprights are kinda flimsy looking no?
[03:24:05] <r00t4rd3d> balsa
[03:24:13] <ssi> dunno about 3000ipm, but you gotta cut pretty quick
[03:24:27] <ssi> PetefromTn: they're 1/4" aluminum, and welded to the gantry
[03:24:29] <PetefromTn> Need to tig weld some more ass on there methinks
[03:24:30] <ssi> it's pretty stout
[03:25:00] <PetefromTn> Just bustin your balls man. LOL
[03:25:06] <ssi> it's actually overbuilt as hell
[03:25:10] <ssi> no cutting forces for plasma :P
[03:25:20] <ssi> the damn table weighs 300lb
[03:25:31] <ssi> I'm kinda dumb, and I made it out of 1/4" wall tube
[03:25:37] <r00t4rd3d> just sloppy cuts unless you spend a million on a plasma
[03:25:57] <PetefromTn> is that belt driven?
[03:26:04] <r00t4rd3d> rack and pinion
[03:26:05] <ssi> rack+pinion
[03:26:16] <PetefromTn> jeez thats smokin'

[03:26:47] <ssi> I need to reduce it more
[03:26:51] <ssi> it's 3:1 reduction
[03:26:59] <PetefromTn> Damn millhead probably weighs as much as my van...
[03:27:21] <ssi> I may go to a smaller pinion... can't really reduce in the belt reduction any further

[03:28:25] <Tom_itx> small drills
[03:28:27] <Tom_itx> always
[03:28:37] <PetefromTn> Ya know what amazed me about it is when I made that test cut today I could not see ANY chips anywhere.. Talk about chip evac..
[03:28:44] <ssi> I prefer to spot drill
[03:28:44] <PetefromTn> basically always...
[03:28:49] <r00t4rd3d> i send 1/4 holes all the time

[03:29:16] <generic_nick|2> i always center drill
[03:29:39] <ssi> I want to add a spot drill to my plasma table
[03:29:47] <PetefromTn> Read something on PM yesterday about how it is actually bad to use a center drill as a predrill.
[03:29:49] <Tom_itx> it's just a good idea in general to spot drill first
[03:30:03] <Connor> What?
[03:30:04] <ssi> that was the most disappointing part of plasma for me... small holes don't cut well, and if you pilot them, it hardens the plate enough that it's a bitch to finish drill
[03:30:08] <r00t4rd3d> aspire has peck drill and you can set the parameters
[03:30:11] <Connor> I thought that was what they were for...
[03:30:12] <PetefromTn> You really should use a spot drill that has the same tip angle as the drill you intend to use..
[03:30:16] <ssi> PetefromTn: yea don't use a center drill, use a spot drill
[03:30:34] <Connor> Ahh.. Yea.. I use Center drills all the time..
[03:30:36] <ssi> center drills aren't for spotting
[03:30:36] <r00t4rd3d> i drill with a endmill
[03:30:44] <ssi> they're for drilling 60 degree centers in stock for lathe centers
[03:30:55] <PetefromTn> yes exactly..
[03:30:56] <generic_nick|2> you can get them in different angles
[03:31:27] <PetefromTn> need to pickup a real nice spot drill in the same tip angle as your drills..
[03:31:36] <ssi> I don't bother with the same angle as my drills
[03:31:37] <PetefromTn> Probably a 1/2 incher...
[03:31:41] <ssi> I run a 90 degree spot drill, and that's fine
[03:31:52] <Connor> I'm not a machinist.. So.. I didn't know..
[03:31:52] <ssi> but yea, center drill is the wrong tool for the job
[03:31:54] <PetefromTn> what are your drills?
[03:32:01] <ssi> mostly 118
[03:32:02] <ssi> some 135
[03:32:19] <ssi> my machine shop drills are mostly 118, all my aircraft stuff is 135
[03:32:20] <generic_nick|2> if a hole is that critical, you shouldnt be drilling to a finished dimension anyways.
[03:32:25] <PetefromTn> yeah that is what they were saying it causes the drill to wander upon first contact that way..

[03:41:13] <generic_nick|2> a bit high for the spindle, but the amount of time i save WAY more than pays for the occasional new spindle bearings

[03:51:59] <generic_nick|2> meh, hold out for an hnc
[03:52:19] <PetefromTn> whazza difference?
[03:52:28] <generic_nick|2> cnc vs air
[03:52:48] <generic_nick|2> isnt that one all air operated?
[03:53:31] <PetefromTn> dunno just found it..
[03:53:51] <generic_nick|2> i dont think it has servos or ball screws
[03:54:21] <PetefromTn> really interesting...
[03:56:46] <ssi> you don't want the ahc
[03:56:52] <ssi> I htink it's actually hydraulic
[03:56:54] <ssi> and crazy
[03:57:38] <PetefromTn> okay.... dunno really. Actually what I want is like a slant bed model with gang tooling perhaps an older Cincinatti milacron.

[03:58:46] <ssi> yea that's the one you want
[03:58:50] <ssi> hell that's the one I want
[03:59:01] <generic_nick|2> has the bar feeder too
[03:59:11] <generic_nick|2> wish i had one for my hnc sometimes
[04:00:08] <PetefromTn> how big is that bastard?
[04:00:38] <generic_nick|2> small
[04:00:39] <ssi> not that big
[04:00:57] <ssi> 4klb tops
[04:01:02] <generic_nick|2> 2500lbs or so for the lathe. controller is a beast though
[04:01:02] <ssi> probbaly less
[04:01:08] <ssi> hnc is 2500
[04:01:14] <PetefromTn> we're ditching the controller no?
[04:01:16] <ssi> chnc might be a bit more, bigger spindle
[04:01:21] <generic_nick|2> true
[04:01:25] <ssi> you'lll prolly want the drives and power supply out of the control
[04:01:42] <PetefromTn> yeah so I can sell em...
[04:01:51] <generic_nick|2> but the servo might be more of a direct drive so you loose all the varidrive bs
[04:01:58] <generic_nick|2> or use them
[04:02:12] <ssi> true
[04:02:14] <generic_nick|2> i used the hiak amps and the stock servos
[04:02:24] <generic_nick|2> they work great
[04:02:24] <ssi> me too
[04:02:26] <ssi> worked great
[04:02:26] -!- kmrhb has quit [Ping timeout: 255 seconds]
[04:02:28] <PetefromTn> what size are the sercos..
[04:02:33] <generic_nick|2> tiny
[04:02:36] <PetefromTn> servos..
[04:02:44] <PetefromTn> 130mm
[04:02:46] <generic_nick|2> 20 amp drives though i believe
[04:02:56] <ssi> hnc is 90vdc
[04:02:59] <ssi> dunno about the chnc
[04:03:09] <PetefromTn> they're not AC drives?
[04:03:17] <generic_nick|2> not the hnc
[04:03:37] <generic_nick|2> but no clue. that chnc is old as balls, so maybe dc as well
[04:04:42] <generic_nick|2> you're not going to be doing big work in that thing so no need for big power
[04:05:15] <generic_nick|2> i havent needed any more power anyways
[04:05:26] <PetefromTn> Im likin this guy..http://www.ebay.com/itm/MORI-SEIKI-SL1A-CNC-LATHE-WITH-TOOL-HOLDERS-TAIL-STOCK-SL1A-/271150510399?pt=LH_DefaultDomain_0&hash=item3f21d4713f
[04:06:24] <generic_nick|2> id get that over the hardinge
[04:06:47] <generic_nick|2> but it is much bigger
[04:06:49] <PetefromTn> gotta find a nice one with a blown control LOL...
[04:06:57] <generic_nick|2> they're all over lol
[04:07:02] <generic_nick|2> that one is a bit overpriced
[04:07:08] <PetefromTn> agreed...
[04:07:18] <PetefromTn> nice machine tho...
[04:07:23] <generic_nick|2> you can buy a running sl6 for 5-6k
[04:07:38] <PetefromTn> only thing I don't like is that Mori parts are spensive
[04:07:48] <generic_nick|2> yea but you dont need them
[04:07:53] <generic_nick|2> they're the best lol
[04:07:54] <PetefromTn> LOL..
[04:08:22] <PetefromTn> thats what I hear...
[04:08:29] <generic_nick|2> i ran an sl0, sl3, and an sl6 for years
[04:08:37] <PetefromTn> good machines?
[04:08:47] <generic_nick|2> great machines. only thing that ever went wrong was the fanuc controls
[04:08:58] <PetefromTn> LOL we can fix that right..
[04:09:15] <generic_nick|2> we had some HARD crashes. didnt evne flinch
[04:09:26] <PetefromTn> I'll bet.
[04:09:43] <PetefromTn> If you arent crashing you arent making anything I guess over time...
[04:09:48] <generic_nick|2> lol
[04:10:05] <generic_nick|2> id like an sl0
[04:10:09] <PetefromTn> I hear they are built like a brick outhouse...
[04:10:16] <generic_nick|2> yep
[04:10:18] <PetefromTn> whats the difference
[04:12:12] <generic_nick|2> the number is the size
[04:12:24] <generic_nick|2> 0 is the smallest, and it goes up from there
[04:12:32] <PetefromTn> obviously...
[04:12:44] <PetefromTn> they all have the same features just smalller
[04:12:53] <generic_nick|2> more or less
[04:12:57] <PetefromTn> all slant bed, all tool turret
[04:13:06] <PetefromTn> do they all have tailstock
[04:13:20] <generic_nick|2> i ran a newer mori lathe, like a 2006 model. it was ok but i think the older ones were beefier
[04:13:23] <PetefromTn> whats the HP on SL1
[04:13:32] <generic_nick|2> all the ones we had did
[04:13:40] <generic_nick|2> no clue on numbers
[04:13:56] <PetefromTn> Sure seems like a sweet machine tho...
[04:14:03] <generic_nick|2> yep
[04:14:07] <PetefromTn> Can you get a collet closer?
[04:14:18] <generic_nick|2> no clue. we just had chucks
[04:14:29] <PetefromTn> pneumatic?
[04:14:38] <generic_nick|2> hydro
[04:14:49] <PetefromTn> are the machines hydro?
[04:15:01] <generic_nick|2> servo
[04:15:14] <PetefromTn> so a pump setup just for the chuck?
[04:15:27] <generic_nick|2> yes and maybe turret, i dunno
[04:15:45] <PetefromTn> don't like hydro stuff... too messy and complicated...
[04:15:52] <generic_nick|2> and tailstock
[04:16:03] <generic_nick|2> never had a problem with it
[04:16:26] <generic_nick|2> all power chucks willl bte hydro
[04:16:30] <generic_nick|2> be*
[04:17:15] <PetefromTn> I am gonna want a nice pendant for my Cincinatti Arrow here soon I think. Gotta find one that has an MPG on it that plays nice with LinuxCNC..
[04:17:21] <generic_nick|2> you need to be able to adjust the pressure. same with the tailstock
[04:17:46] <PetefromTn> aah...
[04:19:43] <PetefromTn> Well I am gonna hit the hay here fellas. Nice chatting with you.. peace
[04:20:17] <generic_nick|2> nite
[04:21:10] -!- PetefromTn has quit [Remote host closed the connection]
[04:23:23] <ssi> mhaberler: excellent find!
[04:24:06] <mhaberler> maybe that helps to fill in the quadrature decoder missing spot in Charles' driver
[04:24:18] <ssi> I'm gonna jump into the PRU code here real soon
[04:24:22] <ssi> PWM outs would be good to have too
[04:24:59] <mhaberler> yes, but maybe investigating the existing PWM's first might make sense before doing new ones
[04:25:09] <ssi> true
[04:25:14] <mhaberler> I didnt look into those though
[04:25:28] <ssi> I have a couple applications for the BBB driving machines
[04:25:42] <mhaberler> stepper?
[04:25:47] <ssi> one is redoing my g0602 lathe, which requires two stepgens, an encoder counter (three would be nice), and a pwm out
[04:25:51] <ssi> yea
[04:26:02] <mhaberler> how many ppr
[04:26:14] <ssi> the spindle encoder is 32 I think
[04:26:16] <ssi> pretty coarse
[04:26:19] <ssi> it's homemade
[04:26:44] <ssi> https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-frc1/205204_655375525742_5631970_n.jpg
[04:26:57] <mhaberler> so that wont be more than say 3000 transitions/sec then
[04:27:08] <ssi> it'd be more than that at 3000rpm!
[04:27:13] <mhaberler> oh
[04:27:47] <ssi> I'm hoping that two prus is enough to run four stepgens and four encoder counters at least
[04:27:51] <ssi> but maybe I'm overestimating the hardware
[04:27:55] <mhaberler> well that'd be a bit pushing the envelope with a soft encoder and base thread
[04:28:03] <mhaberler> oh absolutely, enough bang there
[04:28:31] <mhaberler> you need to talk Charles into providing the hooks for other tasklets in the PRU, it might be there already
[04:29:11] <ssi> yea I dunno how configurable pru code is gonna go
[04:29:22] <ssi> might be we just end up with a bunch of different programs, and you load the one you want
[04:30:04] <mhaberler> dont think that will scale; I guess its going to be one binary with all functions assembled in, and select the ones you need based on a config mask
[04:30:17] <ssi> that may work
[04:30:28] <ssi> are there limits to the binary size in the PRU?
[04:30:29] <mhaberler> mask bit set -> execute corresponding tasklet
[04:30:34] <mhaberler> 12k I think
[04:30:50] <mhaberler> pretty hard to exceed with assembly code.. I wouldnt understand it
[04:31:03] <ssi> it's also complex because what pins the PRU grabs (and therefore become unavailable to gpio driver etc) will change based on the tasklets you want
[04:31:22] <mhaberler> yes, that's why the bitmask is needed
[04:31:37] <ssi> yeah I guess that won't be a problem if it's a hal driver that's setting up the PRU
[04:32:02] <mhaberler> that is the case now; HAL driver does incantations, then load PRU binary and start it
[04:32:02] <ssi> pru driver loads first, based on config strings tells pru which tasklets to run, and then marks those pins clamed
[04:32:10] <mhaberler> yes
[04:32:16] <ssi> and honestly the order doesn't even matter
[04:32:28] <ssi> if the gpio driver loads first and claims pins that the pru needs, pru driver will fail
[04:32:34] <mhaberler> that's the point of the bitmask
[04:33:05] <mhaberler> what we do need is a inter-driver convention how to correlate bit number and GPIO pin
[04:33:18] <mhaberler> that's where your offset comes in
[04:33:21] <ssi> keep it simple
[04:33:35] <ssi> two 46 bit masks
[04:33:44] <ssi> first one is P8, second one is P9
[04:34:22] <mhaberler> so we need say macros to convert pin# to bitpos and vice versa
[04:34:39] <ssi> yeah
[04:34:52] <ssi> and those macros can be specific to whatever representation the driver in question uses
[04:34:57] <mhaberler> hm, another list item..
[04:36:09] <ssi> so there's an 8k block of ram in the pru that you can write to from linux code
[04:36:20] <ssi> I guess the strategy is to write control data into that space on the servo-thread
[04:36:27] <ssi> and let the PRU run its own base thread based on your control data
[04:37:44] <ssi> haha gotta love college students
[04:37:45] <ssi> So, if you need precise timing, or more rapid access to a certain GPIO pin, this is a route you might want to look into. There are a few suggestions listed above that might be interesting to see come out of using the PRU. However, if you do not require precisely timed events or faster access to GPIO pins, you might want to consider just using C on the main processor. Much of the information needed to access certain parts of the PRU and the hardware from
[04:38:00] <ssi> "Using the PRU is hard, so we recommend you don't unless you need to, cause it's scary and hard"
[04:38:23] <ssi> also, who starts a paragraph in a research paper with "So, "
[04:38:24] <ssi> :D
[04:40:12] <ssi> http://blog.pignology.net/2013/05/getting-uart2-devttyo1-working-on.html
[04:40:14] <ssi> this is useful too
[04:40:16] <ssi> from Dave's post
[04:41:18] <ssi> oh weird... now I see how you apply an overlay
[04:42:16] <ssi> I'd love to get to a point where we can design some hardware breakout capes that have signal conditioning for specific tasks, and give it an eeprom so it'll load its dto automatically at boot
[04:42:21] <ssi> that would be pretty dang slick

[13:10:28] <jdh> you are a Gentoo Fan?
[13:10:43] <r00t4rd3d> i hate everything
[13:10:44] <timholum> does anyone know if there are any functional linuxcnc machine's running on an arm processor? I would love to have my beaglebone be the heart of a cnc machine, but Last I looked ( 6 months to a year ago ) I could not find any way to get a real time kernel
[13:11:30] <Daywalker198454> hello together... i have a problem. i want linuxcnc to use a second parport but i think linux doesnt load it...
[13:11:58] <jdh> timholum: afaik, a bbb version is in progress
[13:12:17] <jdh> and runnable with some effort
[13:12:25] <r00t4rd3d> Daywalker198454, how did you add the 2nd parport?
[13:12:50] <r00t4rd3d> a cheap pci card?
[13:13:04] <Daywalker198454> just pushed in a free pci slot... normaly i use windows :P
[13:13:12] <Daywalker198454> new on linux
[13:13:13] <timholum> adh: Thanks for the info, do you know where I could download the devel version?
[13:13:19] <timholum> for beaglebone
[13:14:00] <Daywalker198454> under windows no problem
[13:14:04] <PetefromTn> timholum: I think that SSi here is working on the bone setup for linuxCNC

[13:16:40] <r00t4rd3d> lspci and see if the card is listed would be a start
[13:16:41] <timholum> Perfict, I think with this info I should be able to get something working :)
[13:17:10] <Daywalker198454> one moment i will try
[13:17:16] <r00t4rd3d> im dont think any ole pci parport card will work either

[13:29:49] <r00t4rd3d> does he need to define the hardware address of both parports some place?

[13:30:52] <Daywalker198454> i a real noob in linux installed it the first time
[13:31:47] <Daywalker198454> i think linux didnt start the 2nd parport

[14:18:32] <Nick001> loadrt hal_parport cfg="0x378 0xcc008 out" sometimes you have to try one of the other addresses
[14:18:49] <Nick001> in the list
[14:18:55] <Gigs-> there's the harbor frieght type stuff for like $5 but very limited, or the fastenal type which are more specific and cost $100 times more

[14:20:05] <L84Supper> where can I find a hat I can wear so I can lose pounds and inches while earning money while I sleep?
[14:20:25] <Gigs-> If you are making fun of me I don't think my request is unreasonable
[14:20:47] <Gigs-> springs cost a fraction of a cent to make, probably less than bolts, but it's pretty easy to have a fully stocked cabinet of every common bolt size
[14:21:02] <L84Supper> the point is you might be looking for something that isn't available
[14:21:13] <Gigs-> that's why I asked some guys that might know
[14:21:49] <FinboySlick> L84Supper: Only kind of hat that I can think of which might suit that requirement would turn you into a pulp fiction character.

[14:36:58] <generic_nick|2> i want to make a disk encoder for my spindle on my mill

[14:38:50] <generic_nick|2> cool
[14:39:11] <generic_nick|2> i was planning on machining a disk with a bunch of slots in it all the way around
[14:39:21] <GammaX> ill be using one on mine, just have to darken the inside of the splines on my rf45 spindle and polish the outer edges...
[14:39:41] <JT-Shop> GammaX: factory automation
[14:40:03] <GammaX> JT-Shop can you show an example?
[14:42:00] <generic_nick|2> i need 3 of those i assume, 1 each for a,b, and index?
[14:42:22] <generic_nick|2> is index even needed for rigid tapping?
[14:42:28] <GammaX> generic_nick|2 what you putting this on?
[14:42:37] <generic_nick|2> my mill's spindle
[14:42:46] <GammaX> well rigid tapping will need one on spindle.
[14:43:04] <GammaX> you said 3 of them though?
[14:43:11] <generic_nick|2> im just asking
[14:43:21] <generic_nick|2> didnt know if it needed a,b, and z
[14:43:22] <GammaX> well... im gonna be using just 1.
[14:43:45] <GammaX> what kind of system is this going on?
[14:44:01] <generic_nick|2> system?
[14:44:18] <GammaX> what type of machine generic_nick|2
[14:44:20] <generic_nick|2> just on the spindle of my mill running emc
[14:44:27] <generic_nick|2> shizuoka
[14:44:39] <GammaX> got any photos of spindle area?
[14:44:50] <generic_nick|2> not off hand
[14:45:31] <generic_nick|2> i was just going to machine a disk to mount on the spindle up near the pulley
[14:45:44] <generic_nick|2> tons of room after i ditched the varidrive
[14:46:45] <jdh> I dont' think that woudl be a great sensor for a slotted disk
[14:47:19] <generic_nick|2> not even slots that dont go through and i paint the insides black?
[14:47:39] <jdh> that might work
[14:47:46] <GammaX> generic_nick|2 I think it would be great with great reliability.
[14:48:59] <GammaX> if you can take out the spindle if you precision grind some splines on it and then mount the omron to thatarea. no need for a disc at all.
[14:49:06] <generic_nick|2> have you figured out how many ppr at a given rpm it can handle
[14:49:30] <GammaX> that or clamp on like an aluminum coupler with your slots already cut on it.
[14:49:41] <jdh> you could get a spline sensor and not use a disc
[14:49:42] <generic_nick|2> the disk would be way easier....
[14:50:14] <GammaX> jdh thats what im trying to do with my omron.
[14:50:49] <generic_nick|2> there are no splines, i need something big enough in diameter to clear a part of the spindle or ill have to make a big bracket, and the disk is easier
[14:52:16] <jdh> NO!
[14:52:38] <FinboySlick> I DON'T EITHER! ;)
[14:52:49] <GammaX> lol why so hostile man...
[14:53:27] <JT-Shop> would you guys quit hollering I'm trying to take a nap
[14:53:31] <JT-Shop> GammaX: http://imagebin.org/257088
[14:53:35] <generic_nick|2> WHY IS EVERYONE YELLING!
[14:53:40] <PetefromTn> snicker snicker../
[14:54:06] <JT-Shop> some parts for 7 automatics I'm making http://imagebin.org/257089
[14:54:07] <GammaX> LOUD NOISESSS!!!!!
[14:54:14] <JT-Shop> dang that is fuzzy
[14:54:29] <GammaX> JT-Shop Looks great!
[14:54:43] <generic_nick|2> JT-Shop: your press runs on ethernet?
[14:55:13] <FinboySlick> JT-Shop: Don't mention automatics, you'll wake up our local ATF agent.
[14:55:15] <GammaX> haha I just noticed that
[14:56:48] <JT-Shop> yea, I can surf the internet while pressing parts
[14:57:23] <L84Supper> POE = power over ethernet
[14:57:45] <Jymmm> 48V press huh?
[14:57:48] <pcw_home> Purity Of Essence
[14:58:24] <L84Supper> 48, 49 whatever it takes
[14:58:39] <GammaX> does poe realy put out 48v?!
[14:58:55] <Jymmm> up to 48
[14:59:09] <L84Supper> http://en.wikipedia.org/wiki/Power_over_Ethernet
[14:59:11] <GammaX> damn... thats good to know...
[14:59:35] <GammaX> does linuxcnc have capability of controlling a usb based break out board for a stepper system?
[14:59:54] <Jymmm> nope
[15:00:45] <jdh> you have to have a POE injector
[15:00:46] <GammaX> damn
[15:03:46] <pcw_home> Running LinuxCNC with a remote USB controller has been done
[15:03:48] <pcw_home> but it fragments the RT portion of LinuxCNC
[15:03:50] <pcw_home> (this may be addressed in the future with MachineKit that runs
[15:03:51] <pcw_home> all of the RT parts of LinuxNC on the remote device)
[15:04:39] <FinboySlick> The MachineKit concept seems promising.
[15:05:15] <Jymmm> MachineKit ???
[15:05:48] <GammaX> anyone have sonme larger nema 34 steppers there lookin to sell?
[15:06:36] <Jymmm> pcw_home: MachineKit ???
[15:07:13] <pcw_home> at the minimum the remote device probably needs fast floating point,
[15:07:15] <pcw_home> sufficient memory for HAL, Motion,Task,and a communication method
[15:07:16] <pcw_home> which may rule out a number of existing USB stepgen/IO devices
[15:07:19] <PetefromTn> JT-Shop: what the hell are those things?
[15:07:53] <GammaX> Also annyone running a Hitachi sj200 vfd?
[15:08:14] <PetefromTn> sorry WJ200...
[15:08:18] <Jymmm> PetefromTn: (industrial sex toys)
[15:08:21] <generic_nick|2> ok time to plan my shop layout. and figure out how im going to move my mill....
[15:08:27] <PetefromTn> LOL....smartass.
[15:08:49] <PetefromTn> I thought all CNC's were industrial sex toys LOL
[15:08:49] <Jymmm> PetefromTn: you would think, but Noooooooooooooooooo
[15:09:00] <GammaX> PetefromTn should be closenough... you running it with linuxcnc?
[15:09:07] <PetefromTn> yuppers
[15:09:34] <JT-Shop> PetefromTn: servo motors, gear boxes, linear slides, bits and pieces
[15:09:44] <GammaX> PetefromTn classic ladder or someother way?
[15:10:11] <Jymmm> PetefromTn: Here, watch some CNC pr0n http://www.youtube.com/watch?v=A_qHR_H_2cg
[15:10:12] <Tecan> (A_qHR_H_2cg) "CTX gamma 2000 TC" by "GILDEMEISTERTV" is "Tech" - Length: 0:08:58
[15:10:51] <PetefromTn> Right now I have not gotten to the toolchanger still working on the basic three axis system and spindle control with linuxCNC...gotta get my spindle encoder installed before I can rigid tap and index for toolchange...
[15:11:37] <JT-Shop> when they are done they go on an assembly line to lift and rotate pallets (not the kind for shipping) as needed to present the correct side of the engine to the automatic assembly machines
[15:12:02] <PetefromTn> SWEET....you are not new at this then Right LOL
[15:12:27] <PetefromTn> CNC porn is GOOD PORN....shiny stuff...drool.
[15:13:44] <generic_nick|2> hmmm maybe i can put an anchor in my floor and use a snatchblock with a winch to pull the mill
[15:14:54] <Jymmm> generic_nick|2: get yourself 5-10 1/4" steel rods. use them as "rollers"
[15:15:12] <PetefromTn> ya know I watch that multi axis machine video and think to myself......jeez man I can think of about a hundred ways to crash the crap out of that monster LOL...
[15:15:29] <generic_nick|2> too heavy to lift, and it wont roll without mechanical help
[15:15:30] <GammaX> generic_nick|2 id go for rolling and eth an electric or hand crnk winc
[15:15:59] <generic_nick|2> it's a 7000lb mill
[15:16:43] <GammaX> craigslistmight have a guy offeriung forklift service
[15:16:58] <generic_nick|2> no, cant do that here
[15:17:03] <PetefromTn> I have moved several heavy machines using steel small diameter pipes as rollers...
[15:17:52] <generic_nick|2> ive moved this machine tons of times, it's a knee mill and rollers are a PITA
[15:18:22] <PetefromTn> yeah they are but they work and are cheap. You can go rent some machine skates if you want. Or build some...
[15:19:26] <generic_nick|2> na i want an anchor in the floor for pulling broken vehicles into my driveway anyways

[15:28:34] <JT-Shop> generic_nick|2: they do come in handy if you don't have a tree near by
[15:29:39] <generic_nick|2> i bet.
[15:30:12] <generic_nick|2> i think after i move my shop i may try and sell my house and move somewhere where i actually have room for a backhoe

[15:37:34] <JT-Shop> ssi: 12,500 if I'm not on it

[15:39:12] -!- L33TG33KG34R has quit [Ping timeout: 264 seconds]
[15:39:17] <ssi> wait, wait no
[15:39:33] <ssi> The requirement for a type rating is limited to large (greater than 12,500 lbs MGTOW)
[15:39:40] <ssi> that means 12,501 requires a type rating
[15:39:43] <ssi> 12,500 doesn't :D
[15:39:55] <ssi> I can never remember which side of the fencepost it falls on
[15:42:36] <JT-Shop> what's a type rating?
[15:42:50] <ssi> sorry, stupid pilot jokes
[15:43:07] <JT-Shop> ok, I'm with you now
[15:43:07] <ssi> type rating is a special certificate that you have to hold in order to fly a particular type of aircraft
[15:43:17] <ssi> every aircraft over 12,5 requires one
[15:43:32] <ssi> but the key word there is "over"
[15:43:35] <JT-Shop> biggest I ever flew was a Cessna 310
[15:43:45] <JT-Shop> dunno what it weighed
[15:43:52] <JT-Shop> it was my Dads
[15:44:02] <ssi> there's lots of planes where they intentionally set the GTOW at 12,500 even though it could technically be higher, just to avoid having to be typed in it
[15:44:06] <ssi> a 310 is about 4k GTOW
[15:44:20] <ssi> 4600 actually
[15:44:23] <JT-Shop> IIRC a slick sombeach when pointed downhill
[15:44:23] <ssi> 2850 empty
[15:44:37] <ssi> 12,5 is a BIG airplane
[15:44:41] <ssi> or a small bulldozer :)
[15:44:48] <JT-Shop> yea, it gives me some scale now
[15:44:56] <JT-Shop> I need a small dozer
[15:45:42] <ssi> I need to get a trailer that I can put my forklift on
[15:45:47] <ssi> and also move machinery with
[15:46:11] <ssi> I figure a 12klb rated trailer would do it
[15:46:19] <ssi> the trailer itself will weigh 3k or so
[15:46:40] <ssi> but the ramp for the forklift is the hard part
[15:46:55] <ssi> it's solid tire :(
[15:47:26] <JT-Shop> yea, they are hard to load without a dock
[15:47:40] <ssi> rollback would be nice :P
[15:47:44] <ssi> but a bit out of my price range
[15:47:48] <JT-Shop> the local rental place has a drop bed trailer for the hard tire forklifts
[15:48:01] <r00t4rd3d> I have OSHA forklift certification :)
[15:48:08] <ssi> not me
[15:48:11] <ssi> I'm thoroughly unsafe
[15:48:14] <r00t4rd3d> not that its hard to get
[15:48:27] <generic_nick|2> i remember some joker who came to buy a mill from me tried loading a forklift on some old ass wood deck trailer and it fell through
[15:48:32] <ssi> we used to have drunken parties and I'd put five or six people on a pallet and raise them eight feet in the air and do donuts
[15:48:39] <r00t4rd3d> i use to load tractor trailers, had to get it.
[15:48:49] <ssi> OSHA BE DAMNED
[15:49:57] <generic_nick|2> ssi, we just lift my jeep up when we get drunk around the forklift. http://farm9.staticflickr.com/8263/8705860068_1a4372a41f_c.jpg

[17:27:19] <ssi> PetefromTn: no I prefer you fail and are forced to sell it to me for what you have in it
[17:27:57] <PetefromTn> Now why the hell would I do that. at least if I do fail I can tell the wife it is worth WAY more than I have in it LOL...
[17:29:05] <ssi> hahahaha
[17:29:25] <ssi> seriously I gotta find me something like that
[17:29:59] <Connor> Okay, So, I need to make a one-off part... It's a rectangle part, with a U shape cut into the center.. and 4 holes (one in each corner).. I can't use the vise because it would run it into the jaws..
[17:30:19] <PetefromTn> I am really likin it.... Especially when I made that circular interp last nite and it was only .0001 out of spec LO..
[17:30:40] <GammaX> Connor how would it do that?
[17:30:44] <ssi> yea that's awesome
[17:30:47] <Connor> so, I guess I need to use hold down clamps.. but.. I don't want to reposition the clamps to drill the freaking holes... it's not a very large part either.. about 4" wide and 2.5" deep
[17:30:52] <ssi> I love the crap out of my HNC... it's an amazingly precise machine
[17:31:04] <GammaX> PetefromTn are ou using modbus to control that vfd>
[17:31:06] <GammaX> ?
[17:31:06] <ssi> the guy I Bought it from was making fuel nozzles for jet engines out of inconel

[17:31:46] <PetefromTn> Connor: you need to bolt a plate to the vise and then drill and tap that for the hold down bolts in the four holes, then use them to clamp the part while you machine the slot...
[17:32:07] <PetefromTn> nope...just linuxCNC and the 7i77 card.
[17:32:29] <Connor> I guess I could also cut the bar down slightly over sized.. mill the ends.. and mount it long ways in the vise since I have a 5" vise..
[17:32:48] <Connor> that would allow me access to the side that I need to cut U shape.
[17:32:49] <PetefromTn> always more than one way....
[17:32:56] <GammaX> PetefromTn so a ladder?
[17:33:30] <PetefromTn> LOL no man no ladder yet just basic linuxCNC. The ladder will come once I get spindle orientation wired up and it will control the toolchanger...
[17:34:54] <GammaX> basiclinuxcnc...
[17:35:07] <GammaX> i guess im just confused cause I didnt know it could be done...
[17:35:44] <Connor> PetefromTn: Or the Remap functions without Ladder. :)
[17:36:06] <PetefromTn> Connor: yes exactly just as soon as you figure out how for me LOL
[17:36:55] <PetefromTn> the 7i77 card has ability to use the sixth axis setup for spindle control. It has enable and 0-10v outputs to control the unit...
[17:37:21] <Connor> PetefromTn: Next steps are wiring in all those prox sensors.. and finding out more info on the Toolchanger motor.
[17:37:30] <GammaX> PetefromTn damn I forgot... i dont have mesa :(

[19:10:39] <cpresser_> generic_nick|2: the datasheet says that the led about 1.2V; the maximum current for the LED is 50mA
[19:11:22] <generic_nick|2> the minimum voltage is 1.2v? or max?
[19:11:38] <cpresser_> the detector will work at 5V; see the 'light current cs. collector-emitter-voltage' plot
[19:12:12] <generic_nick|2> ahh
[19:12:36] <cpresser_> you need to design two circuits. one for the led, one for the detector

[23:22:00] <r00t4rd3d> i would rather use windows then ubuntu any day of my life
[23:22:05] <LokiScarlet> Uh... I'm completely new to CNC equipment, and I'm trying to figure out if this machine they have at work will work with LinuxCNC... It's a FlexMate from the good ol DOS days
[23:22:18] <LokiScarlet> Or.. The boards are FlexMate
[23:22:19] <generic_nick|2> yea i was going to say, ive had more issues with ubuntu...
[23:22:29] <ssi> I don't use ubuntu as a desktop either
[23:22:39] <ssi> I use it to run CNC machines, and we use it for servers at work
[23:22:43] <ssi> it's fine for both
[23:22:53] <generic_nick|2> i tried linux, it just doesnt work with netflix so it's useless
[23:23:04] <r00t4rd3d> lol
[23:23:06] <generic_nick|2> or any other program i want to use for that matter
[23:23:07] <LokiScarlet> >doesn't work with netflix
[23:23:09] <LokiScarlet> That's what you think
[23:23:44] <generic_nick|2> LokiScarlet: did they find a hack for it yet?
[23:24:18] <ssi> chap
[23:24:20] <ssi> crap evens
[23:24:21] <LokiScarlet> There's always a way. If nothing else, there's the web interface
[23:24:30] <ssi> sheetcam on linux runs, but then aborts with an error and won't tell me what it is
[23:24:51] <generic_nick|2> but i can just use windows and it works without finding a way lol
[23:24:53] <LokiScarlet> ssi: Tried /var/log/sheetcam or something like that?

[23:25:16] <LokiScarlet> generic_nick|2: Or you can do what I'm about to do and wipe everyhing with NetBSD
[23:25:52] <ssi> that'd be way too easy :P
[23:25:59] <ssi> there is some stuff in /var/log/messages though, let's see
[23:27:12] <ssi> no, nothing useful
[23:27:15] <ssi> this is the error: We are very sorry but SheetCamTNG-dev has encountered an internal error. It would be very helpful if you could send a debug report so we can try to find out what went wrong
[23:27:20] <ssi> SUPER helpful
[23:27:44] <andypugh> If you re-start it is there are send-error-report option?
[23:27:52] <ssi> yeah I sent an error report
[23:28:00] <ssi> although that threw an error too
[23:29:08] <andypugh> Les is generally pretty responsive.
[23:29:13] <ssi> I think it failed to create the support.zip file
[23:29:23] <ssi> maybe I'll try to contact him directly
[23:29:31] <ssi> I did actually pay for a copy of the license once upon a time

[23:30:53] <ssi> no
[23:31:02] <nathanstenzel> anyone here use both a cnc mill and a 3d printer?
[23:31:26] <LokiScarlet> What do you run to run the program?
[23:31:56] -!- slifty has quit [Quit: Leaving...]
[23:32:00] <LokiScarlet> Like, filename if it's in your bin path, full path if it's somewhere else
[23:32:47] <ssi> nathanstenzel: yea lots of people
[23:33:03] <ssi> LokiScarlet: there's a run_sheetcam script
[23:33:15] <ssi> just sets LD_LIBRARY_PATH
[23:33:23] <nathanstenzel> I ask because I was wondering if the programs for manipulating the gcode and doing the slicing and such is all that different
[23:33:30] <ssi> nathanstenzel: yeah somewhat

[23:39:07] <nathanstenzel> can you use slicer and repetier for cnc milling too?
[23:42:05] <Tom_itx> that might be better asked in #reprap
[23:43:41] <nathanstenzel> hmmm....is this channel for software called "linuxcnc" or is it for cnc milling on linux?
[23:43:45] -!- stsydow has quit [Remote host closed the connection]
[23:44:09] <r00t4rd3d> bot
[23:44:10] <Tom_itx> yes
[23:44:10] <r00t4rd3d> h
[23:44:48] <nathanstenzel> so it is for linuxcnc software as opposed to repetier and slicer?
[23:45:09] <Tom_itx> yes
[23:45:21] <Tom_itx> thus the channel name
[23:45:33] <nathanstenzel> ah. I guess you are right then. I misunderstood that whole website

[23:53:09] <r00t4rd3d> pcb milling i am sure
[23:53:29] <PCW> Solder paste dispensing and pick and place as well
[23:53:53] <mercuryrising__> I'm having a lot of trouble getting stability back in linuxcnc (took me about a week to get the computer back up and running, so many errors) - but I'm getting closer! I can start a job now, but the computer will freeze (no error reported) or linuxcnc will break (with this error) - http://pastebin.com/myURPLyA
[23:54:12] -!- Nick001-Shop has quit [Ping timeout: 276 seconds]
[23:54:14] <mercuryrising__> nathanstenzel, Yes you can, I have one that was working great until my computer decided to stop working last week
[23:54:21] Nick001-Shop_ is now known as Nick001-Shop
[23:55:24] <nathanstenzel> it seems that CNC machines are more flexible than the printers. The printers do not seem to use swapable tools as often
[23:56:52] <nathanstenzel> any idea if rostock max can be used for CNC milling? It is a delta type 3d printer based on pick and place machines
[23:57:33] <nathanstenzel> it seems really fast for a pick and place machine. it is a pitty that 3d printing is so slow. probably milling would be just as slow on it.
[23:57:54] <mercuryrising__> not sure, might want to check with reprap, they probably have more experience with this stuff
[23:58:22] <PCW> machine check event sounds like your computer is dying...
[23:58:44] -!- stsydow has quit [Client Quit]
[23:58:59] <mercuryrising__> how so? when do they kick in?
[23:59:55] <PCW> take a look at your kernel log
