[02:16:10] <tjtr33> on a 5i25, the 1st 4 inputs can be used as low-rez analog inputs. Anyone have experience with this?

[02:23:35] -!- Sigmac has quit [Quit: Sleeping]
[02:23:42] <pcw_home> tjtr33: on a 7I77 ( or 7I76 or 7I84) not a 5I25
[02:25:58] <pcw_home> (or 7I70 which has 6 channels)
[02:28:00] <tjtr33> pcw_home, yes you're right, on a 7i77. i read the 1st 4 inputs could be read as analog inputs ( like a pot )
[02:28:13] <pcw_home> Yeah
[02:29:44] <tjtr33> oh, so i just read hm2_5i25.0.7i77.0.0.analogin0 as a float! doh! thats way cool
[02:29:57] <pcw_home> Its fairly funky ( its basically a side effect of the fact the digital inputs are all read as analog and processed for hysteresis, threshold etc)
[02:30:14] <pcw_home> so 8 bits and 36V full scale
[02:30:29] -!- koo6 has quit [Ping timeout: 244 seconds]
[02:31:06] <tjtr33> good enuf for say the THC input? ( after some large watt resistor divider )
[02:31:23] <pcw_home> possibly
[02:32:05] <tjtr33> thx, i'll avoid one of those 4 so i can play with it later
[02:32:35] <pcw_home> input impedance is 22K so a 180K resistor for ~300V FS
[02:33:12] <tjtr33> FS?
[02:33:20] <pcw_home> Full Scale
[02:33:33] <tjtr33> ok
[02:33:52] <pcw_home> Hmm not sure if the polarity may be wrong :-(
[02:34:21] <pcw_home> its unipolar of course + only
[02:34:42] <tjtr33> i can feed my idea thru a bridge to insure pos polarity always
[02:35:22] <tjtr33> heh a bridge is like abs()
[02:36:04] <pcw_home> yeah but not sure you want to float the input GND at plasma voltage
[02:36:47] <pcw_home> that could bite!

[06:31:49] <asah> hey yes...
[06:32:10] <zeeshan> my conversion is going slow :P
[06:32:20] <asah> join the club.
[06:32:22] <zeeshan> haha
[06:32:26] <zeeshan> im literally replacing everything
[06:32:29] <zeeshan> electronics wise
[06:32:32] <asah> I just got thw whole thing working after 10 months.
[06:32:35] <Connor> http://chattanooga.craigslist.org/tls/4713493919.html
[06:32:36] <zeeshan> nice!
[06:32:45] <zeeshan> asah: you got your hydraulics working?
[06:32:46] <asah> and I want to do much more in the niceties department.
[06:32:48] <asah> yep.
[06:32:59] <zeeshan> connor get it!
[06:33:02] <zeeshan> wow
[06:33:02] <asah> I am sharing my vfd between the spindle and the hydros pump.
[06:33:07] <Connor> I have no room for it.
[06:33:09] <zeeshan> asah ahh cool
[06:33:13] <zeeshan> i have vfd for hydraulic pump
[06:33:15] <zeeshan> anotehr for coolant
[06:33:16] <zeeshan> and one for spindle
[06:33:21] <zeeshan> a little excessive :P
[06:33:37] <zeeshan> asah is your hydraulic pump on ALL the time?
[06:33:43] <zeeshan> only when you do a tool change
[06:33:46] <asah> no. just for tool changes
[06:33:52] <zeeshan> so you have one button that energizes it
[06:33:55] <zeeshan> a pressure light comes on
[06:33:56] <asah> so I have a contactor switchero setup.
[06:34:05] <zeeshan> and then you press another button to energize the solenoid?
[06:34:18] -!- amiri has quit [Ping timeout: 265 seconds]
[06:34:18] <zeeshan> to allow fluid flow to cylinder?
[06:34:23] <asah> well, I wrote a python component to do those things automagically.
[06:34:31] <asah> but essentially yes.
[06:34:42] <zeeshan> check this video out
[06:34:46] <zeeshan> this is the issue i was having with my pump
[06:34:54] <asah> its complicated by the fact that the vfd resource is shared between the two motors.
[06:35:02] <zeeshan> http://www.youtube.com/watch?v=erP1e3bOqys&list=UUy-Z-COl0WvPmSLXMOvtedg
[06:35:18] <Connor> asah: Why is it shared ?
[06:35:22] <asah> Ill likely get another dedicated vfd for the hydros, but this works till then.
[06:35:42] <zeeshan> my hydraulic pump isnt happy
[06:35:43] <zeeshan> :P
[06:35:44] <asah> cause my old vfd for the hydros was not rated high enough to run off single phase.
[06:36:03] <zeeshan> asah according to my motor specs for hydro
[06:36:08] <zeeshan> its only .25kW
[06:37:33] <asah> not fun… so the pressure switch never trips?
[06:37:43] <asah> that motor does not sound happy.
[06:37:44] <zeeshan> no it does
[06:37:50] <zeeshan> notice how it went to infinity
[06:37:53] <zeeshan> on the ohmmeter?
[06:37:56] <zeeshan> for a little bit
[06:38:03] -!- gennro has quit [Remote host closed the connection]
[06:38:16] <zeeshan> i decoupled the motor from the hydraulic pump
[06:38:17] <asah> I have some partes in my manual I didn’t scan.
[06:38:19] <zeeshan> and it runs fine
[06:38:35] <asah> which may be helpful. (did you get the rest of those scans ok?)
[06:38:40] <zeeshan> btw thanks so much for the link
[06:38:42] <zeeshan> they helped :)
[06:38:48] <zeeshan> infact thats where i figured out the operation for the hydraulic pump
[06:38:51] <asah> it describes the hydros setup on my mill.
[06:38:58] <Connor> could it be that the pump needs work? Like bad bearings ?
[06:39:05] <zeeshan> connor im not sure yet
[06:39:09] <zeeshan> i still have to take the pump apart
[06:39:13] <zeeshan> ands ee whats going on inside
[06:39:20] <zeeshan> ill do it later this week
[06:39:23] <zeeshan> i got an exam this wednesday
[06:39:25] <asah> that is a different pump than I have.
[06:39:25] <zeeshan> studying :(
[06:39:35] <Connor> I told you a while back the pump was for the draw bar.. you must have not seen me say it..
[06:39:40] <asah> mine is a small hawe power pack.
[06:39:43] <zeeshan> connor i know it is!

[06:39:52] <zeeshan> asah ah okay
[06:39:57] <zeeshan> mines a small bosch power pack :P
[06:40:03] <zeeshan> with 1 pressure switch
[06:40:07] <zeeshan> and 1 solenoid valve
[06:40:36] <zeeshan> asah: got videos of your mill in action? :D
[06:40:47] <asah> =) not yet.
[06:40:53] -!- Thetawaves [Thetawaves!~Thetawave@156-96-178-69.gci.net] has joined #linuxcnc
[06:41:17] <asah> still much to do. I have all the panels stripped off the thing. going to paint some of them.
[06:41:33] <asah> making a new console for the monitor and keyboard setup… the fun never stops.
[06:41:49] <asah> super excited to be able to swap tools though!
[06:42:33] <asah> what are you studying zeeshan?
[06:42:45] <zeeshan> "advanced structural mechanics"
[06:42:47] <zeeshan> graduate course
[06:42:49] <zeeshan> its driving me insane
[06:43:02] <asah> what degree you going after?
[06:43:12] <zeeshan> masters of applied sciene
[06:43:14] <zeeshan> mech eng
[06:43:23] <asah> fun stuff.
[06:43:29] <zeeshan> dude
[06:43:36] -!- Thetawaves has quit [Client Quit]
[06:43:37] <zeeshan> how did you figure out what tool holder
[06:43:40] <zeeshan> and retention knob your machine uses?
[06:43:57] <asah> manual.
[06:44:04] <asah> and previous owner.
[06:44:19] <zeeshan> check this out
[06:44:19] -!- gennro_ has quit [Ping timeout: 258 seconds]
[06:44:21] <asah> I have the full manual set.
[06:44:26] <zeeshan> youre lucky!
[06:44:36] <asah> yes… very.

[06:44:46] <zeeshan> thats what my drawbar looks like
[06:44:53] <zeeshan> it doesnt look like it pulls on a pull stud
[06:45:02] <zeeshan> cause currently its in the closed position
[06:45:07] <zeeshan> and it looks too far open
[06:45:11] <asah> have you tried mazak like mine?
[06:45:16] <zeeshan> no
[06:45:17] <zeeshan> im afraid
[06:45:20] <zeeshan> i dont want to jam the tool :P
[06:45:37] <zeeshan> https://www.flickr.com/photos/128539016@N05/15616955925/in/photostream/
[06:45:42] <zeeshan> this is one of the tools that came with the machine
[06:45:51] <zeeshan> but the previous owner told me he doesnt know if it belogns with it :P
[06:46:14] <asah> does he taper fit?

[06:46:23] <zeeshan> i cant check
[06:46:28] <zeeshan> thats the most i can get it in
[06:46:36] <zeeshan> cause my hydraulics isnt working :)
[06:46:41] <asah> =)
[06:46:53] <zeeshan> online i found specs saying
[06:46:55] <asah> looks like you can build pressure on the hydros though.
[06:46:56] <zeeshan> 'iso40 din2080'
[06:47:10] <zeeshan> yes
[06:47:14] <zeeshan> but i dont wanna burn the pump or motor
[06:47:20] <zeeshan> so im gonna try to fix the overload condition first
[06:47:31] <zeeshan> these components are kind of expensive to replace!
[06:47:38] <asah> the solenoid on mine took a fair bit of current like 1.2 @ 24v
[06:47:45] <zeeshan> wow
[06:47:56] <asah> yeah, I was surprised.
[06:47:57] <zeeshan> i guess it'll need a relay
[06:48:03] <asah> thats what I had to do.
[06:48:03] <zeeshan> cant pass it right through mesa
[06:48:03] <zeeshan> :/
[06:48:10] <asah> then it worked fine.
[06:48:12] <zeeshan> i think mesa is 300mA
[06:48:13] <zeeshan> max
[06:48:30] <zeeshan> 7i77 that is
[06:48:33] <asah> I tried to run it off that and no dice.
[06:48:46] <asah> (I have 7i70 and 7i71 io boards)
[06:49:47] <Connor> Don't forget to put fly-back diodes on the relays.
[06:50:03] <zeeshan> doesnt mesa sell a relay card
[06:50:03] <zeeshan> ;/
[06:51:17] <zeeshan> Because of thermal limitations there is a maximum p er driver chip total current of 1.4 amps continuous. Each driver chip connects to 8 sequential outputs. If this limit is exceeded, the driver chip may go into thermal shutd own
[06:51:25] <zeeshan> hehe
[06:51:27] <asah> their spindle interface card works as relay card.
[06:51:54] <asah> I had some nice siemens contactors that lived in the maho originally.
[06:52:13] <asah> total overkill to switch 24v… but thats what I had lying around. =)
[06:53:37] <zeeshan> haha
[06:53:52] <zeeshan> i have an abundance of those contactors!
[06:54:19] <zeeshan> http://i.imgur.com/A0ZB0HS.jpg
[06:54:22] <asah> I bet you do. and a ton of wire...
[06:54:24] <zeeshan> i gutted that cabinet out
[06:54:27] <zeeshan> completely
[06:54:43] <asah> same ones. =)
[06:54:47] <zeeshan> haha
[06:54:57] <zeeshan> i sold the servo drive unit
[06:55:03] <zeeshan> and tnc 150
[06:55:05] <zeeshan> it sold in 3 days
[06:55:05] <zeeshan> haha
[06:57:49] <asah> wow.
[06:57:53] <asah> I should try that too.
[06:57:55] <asah> ebay?
[06:57:57] <zeeshan> yes
[06:58:05] <zeeshan> i made 1000 of them
[06:58:08] <zeeshan> or 1200
[06:58:09] <zeeshan> i forget
[06:58:14] <zeeshan> it was ridiculusly high
[06:58:18] <asah> wow.
[06:58:23] <zeeshan> fyi
[06:58:25] <zeeshan> each one of those cards
[06:58:28] <zeeshan> in the servo drive unit
[06:58:33] <zeeshan> costs 900$--1000
[06:58:54] <asah> crazy.
[06:59:11] <asah> that was the bosch setup?
[06:59:20] <zeeshan> yes
[06:59:22] <zeeshan> bosch tr10
[06:59:28] <zeeshan> and heidenahin tnc140

[06:59:29] <zeeshan> 150
[06:59:35] <asah> cool.
[07:00:01] <asah> I will have to start taking some pics of stuff in my boxes labeled maho. =)

[07:00:19] <zeeshan> thats one card
[07:00:23] <zeeshan> from the heidenhain
[07:00:23] <zeeshan> lol
[07:00:33] <asah> mine is a phillips control.
[07:00:35] <asah> 432.
[07:00:37] <zeeshan> oh
[07:00:44] <zeeshan> does your machine have glass scales?
[07:00:48] <asah> yes.
[07:00:52] <asah> same ones I believe.
[07:00:55] <zeeshan> by who
[07:00:56] <asah> heidenhain scales
[07:01:01] <zeeshan> so you have an interpolator?
[07:01:04] <zeeshan> card
[07:01:06] <asah> yes.
[07:01:09] <zeeshan> exe?
[07:01:11] <asah> yes.

[07:01:24] <zeeshan> i bought those
[07:01:26] <zeeshan> i hope they work
[07:01:31] <zeeshan> still waiting for them to arrive
[07:02:08] <asah> did you check the current rating and match it?
[07:02:36] <asah> that one looks way more advanced than mine. =)
[07:03:14] <zeeshan> i just used the fact
[07:03:17] <zeeshan> that theyre 11uA scales
[07:03:50] <asah> http://www.practicalmachinist.com/vb/attachments/f48/94721d1387856588-maho-mh400e-retrofit-linuxcnc-exe_board.jpg
[07:03:59] <asah> cool. should work then. =)
[07:04:01] <zeeshan> wow
[07:04:02] <zeeshan> those are nice!
[07:04:16] <asah> old school discrete logic.
[07:04:40] <zeeshan> what model is your scale
[07:04:42] <asah> it has nice test points on it that have been very helpful.
[07:04:43] <zeeshan> ls #?
[07:05:19] <asah> LS 403
[07:05:32] <zeeshan> http://www.braunem.de/fileadmin/user_upload/downloads/Datenblaetter/Vergleichstabell_fuer_Messsysteme.pdf
[07:05:34] <zeeshan> i used this pdf
[07:05:41] <zeeshan> notice how it says ls 905 -> 11 uA
[07:05:50] <zeeshan> yours are also 11uA
[07:05:50] <zeeshan> :D
[07:07:33] <asah> I don’t see a 905 on there. =)
[07:07:57] <asah> 904 yes…
[07:08:18] <zeeshan> my bad
[07:08:20] <zeeshan> i meant 904
[07:09:00] <asah> cool. you can do both 5 and 10 x interp.

[07:09:06] <zeeshan> this was the original interpolator card
[07:09:07] <zeeshan> w/ the machine
[07:09:07] <asah> with that exe
[07:09:14] <zeeshan> im not too good with microelectronics
[07:09:17] <zeeshan> so i didnt bother figuring it out :P
[07:09:31] <zeeshan> but the chips look very similar to the one yours uses
[07:09:35] <asah> yeah, that one looks rough.
[07:09:43] <asah> mine was all nice and self contained.
[07:09:48] <zeeshan> nice
[07:09:57] <zeeshan> i'd like to run 10x
[07:10:01] <zeeshan> precise!
[07:10:03] <asah> I would bet.
[07:10:05] <asah> =)
[07:10:20] <zeeshan> itll prolly be a couple of weeks
[07:10:23] <zeeshan> before i can get it running
[07:10:26] <zeeshan> so much to do :/
[07:10:27] <asah> or months.
[07:10:28] <asah> =)
[07:10:30] <zeeshan> haha
[07:10:35] <asah> started out with weeks for me.
[07:10:45] <asah> and things go on and on.
[07:10:53] <asah> and life gets in the way…
[07:11:14] <asah> I started in in ernest around christmas last year.
[07:11:28] <zeeshan> wow
[07:11:32] <asah> got it all working with three phase on the old power system.
[07:11:36] <zeeshan> it took about 2 months to do my lathe
[07:11:39] <zeeshan> but that was completely custom
[07:11:39] <asah> (drives I mean)
[07:12:26] <asah> now having to pull and redo all the drive systems, replace servos, make mounts etc...
[07:12:35] <zeeshan> what servo drives are you using
[07:12:37] <zeeshan> i forget :)
[07:12:50] <asah> not to mention I am a bit crazy at work. (starting a robotics company ) =)
[07:12:55] <asah> mesa 8i20
[07:13:01] <zeeshan> ah cool
[07:13:08] <zeeshan> nice
[07:13:31] <asah> I imagine I am never going to be done with the thing… but in a good way.
[07:13:41] <asah> I have lots of proejcts planned. =)
[07:14:06] <asah> nice manual input is needed. (jog knob )
[07:14:18] <asah> etc...
[07:15:02] <zeeshan> :D

[07:18:40] <asah> which… the gear changing servos ?
[07:18:43] <asah> yes.
[07:18:49] <asah> 18 speed gearbox on mine.
[07:18:58] <zeeshan> haha
[07:19:07] <zeeshan> i want to elimiante it somehow
[07:19:08] <zeeshan> =/
[07:19:14] <zeeshan> i just want high and low gear
[07:19:24] <zeeshan> i was looking at your manual
[07:19:27] <zeeshan> seems a bit complicated :P
[07:19:49] <asah> quite...
[07:20:41] <asah> I am looking to do the same thing (use vfd to do the fine tuned speeds)
[07:21:09] <asah> looks possible… I just haven’t figured out which exact gears to use...
[07:21:26] <zeeshan> yes
[07:21:50] <zeeshan> thsoe gear changing servos might be nice to have
[07:21:50] <asah> I can manually switch them easily.
[07:21:54] <zeeshan> for lets say you want to do

[07:23:06] <asah> I built a component to do the changing… so I am pretty far along the pike towards full gearbox control.
[07:23:33] <asah> it is a ton of IO and states to keep track of.
[07:23:59] <zeeshan> doh
[07:24:11] <zeeshan> remember how many io it takes? :)
[07:24:12] <zeeshan> roughly
[07:24:15] <asah> In haooy to share those things if they are interesting.
[07:24:21] <asah> happy rather...
[07:24:38] <zeeshan> will definitely ask you when i get there!
[07:25:36] <asah> roughly 10 - 12 inputs, 10-12 outputs.
[07:25:43] <asah> I forget.
[07:26:09] <zeeshan> wow
[07:26:14] <zeeshan> thats a lotta i/o stolen
[07:26:14] <zeeshan> :P
[07:26:19] <asah> yeah.
[07:26:58] <asah> 3-4 states for each stage… three stages.
[07:27:29] <asah> then similar amounts of output.

[14:08:24] <PetefromTn_andro> Yeah I need to get pictures but it was a long day yesterday and we got done really late. Plus it does not look like Mich. The control has been gutted and it is missing the spindle motor etc. Etc.
[14:09:44] <archivist> A kit, I got two microscopes last week as kits, more fun
[14:10:03] <PetefromTn_andro> Someone removed most of the enclosure and it's in pieces. I also need to strip and repaint some of the sheet metal because some asshole painted in with a mop I think.
[14:10:13] <archivist> till "complete" really means parts missing
[14:10:52] -!- sumpfralle has quit [Ping timeout: 240 seconds]
[14:10:57] <PetefromTn_andro> Most of what I need to put it back together is all there just dirty.
[14:12:51] <PetefromTn_andro> What is there physically looks really good tho and it is a fine machine. 15x40 swing and it has a nice heavy duty tail stock and a pretty heavy casting.
[14:13:37] -!- sudobangbang has quit [Ping timeout: 245 seconds]
[14:14:37] <PetefromTn_andro> It has a D1-5 or 6 headstock not exactly sure which one just yet. It's pretty large tho. Much bigger than the D1-4 I had on my 12x36 Asian lathe I just sold.
[14:15:49] <PetefromTn_andro> It has a very large and deep chip trays with a coolant drain into a sump that sits in the tail stock foot
[14:16:48] <PetefromTn_andro> It's made by HH Roberts /Standard Modern in Canada.
[14:18:57] <PetefromTn_andro> All in all it should be basically twice the machine and then some of my 12x36 I had which was a pretty nice little lathe actually so once I get it cnc retrofit working it will be a great addition to my shop.
[14:20:50] <PetefromTn_andro> The only real problem it has is since they removed the spindle motor they must have lost the timing belt pulley for it so I am gonna have to find out what kind of belts it used and then try to find or make one for it.
[14:21:30] <PetefromTn_andro> It was apparently a 5hp or 7.5 hp machine before
[14:22:04] <PetefromTn_andro> There are still three long timing belts in the enclosure that were for the spindle.
[14:23:09] <PetefromTn_andro> I'm going to try to get my hands on a new 5hp face mount three phase motor for it and run it with a vfd most likely
[14:23:11] -!- skunkworks_ has quit [Ping timeout: 244 seconds]
[14:24:12] <PetefromTn_andro> The spindle already has a nice encoder installed on it and there is some kinda sensor going into the headstock case that I am not sure what it is yet.
[14:25:13] <PetefromTn_andro> After breakfast I am going to get out there and start cleaning it up and getting it moved into the place I want it.
[14:25:51] <PetefromTn_andro> This should be a really cool machine retrofit project.
[14:26:24] <PetefromTn_andro> Can't wait to have a nice powerful cnc lathe to work with.
[14:27:06] <PetefromTn_andro> I'll try to get pictures when it is a bit more presentable hehe

[17:08:54] <PetefromTn_> Tom_itx I hear you man. I am still trying to get it moved around in the shop. Honestly that mopped on paint on a lot of the surfaces is not gonna work for me. In fact I have already started to strip it off in a couple spots.
[17:09:04] <PetefromTn_> The good news is that the ways look really nice and smooth.
[17:09:21] <PetefromTn_> No major wear or damage really that I have seen anywhere.
[17:10:20] <PetefromTn_> The X axis has the ballscrew and servo still there along with the heavy timing belt drive that it came with. The Z ballscrew was removed so I will be needing to get one made and they removed the Z axis motor.
[17:10:53] <PetefromTn_> The thats the bad news the good news is they were kind enough to leave all the mounts for the Z ballscrew on all three places both ends and the carriage.
[17:11:26] <PetefromTn_> They seem to have large diameter bearing holes in them and it appears that the Z motor was originally mounted right along side of the headstock
[17:11:56] <PetefromTn_> There is a piece of angled sheetmetal that kinda isolated the work area from that and there is also a cover that went over top of the motor.
[17:12:18] <PetefromTn_> The motor is mounted horiztonally parallel with the Z axis
[17:13:17] <PetefromTn_> There was a small box that came with the machine that has the original heavy belt drive and timing pullies for that Z motor so I guess they probably used the same style Z motor as the X motor. The X motor is quite large
[17:14:02] <PetefromTn_> The X axis carriage sticks out pretty far beyond the rear of the apron and the X motor sits underneath it facing the back of the machine and the belt drive is mounted to a heavy steel plate vertically.
[17:14:07] <Tom_itx> no pics... never happened!
[17:14:15] <PetefromTn_> yeah I hear ya.
[17:14:18] <PetefromTn_> To be honest
[17:14:25] <Tom_itx> it's a good story though :D
[17:14:26] <PetefromTn_> my shop is a fuckin' disaster right now
[17:14:53] <PetefromTn_> I mean I have shit everywhere from moving out the old machine and setting up rigging to move that out and the new one in.
[17:15:21] <Tom_itx> that's what makes it interesting
[17:15:24] <PetefromTn_> Plus my wife has decided to start a woodworking project making some kinda square pumpkin things you put at the front door during halloween
[17:15:41] <PetefromTn_> so I have wood dust, paint and shit everywhere from that.
[17:15:54] <archivist> I always look in the background :)
[17:15:55] <PetefromTn_> And my shop is not that big so a little clutter makes for quite a disaster.
[17:16:09] <PetefromTn_> I will definitely get some pics here soon
[17:16:29] <PetefromTn_> I just wanted to get it sorta cleaned off and put in position to get better photos of it.
[17:16:38] <PetefromTn_> I am very pleased so far with my purchase tho.
[17:16:48] <PetefromTn_> It should be a fine lathe when it is finished
[17:17:08] <PetefromTn_> it should be able to do about anything I could want to with a CNC lathe short of a full blown turning center
[17:17:14] <archivist> we all have teh clutter http://www.collection.archivist.info/archive/DJCPD/PD/2001/2001_10_11_lounge/P1010001.JPG
[17:17:39] <PetefromTn_> yeah but at least yours is sorta organized clutter hehe
[17:17:52] <PetefromTn_> mine right now looks like a bomb went off in a machine shop
[17:18:07] <CaptHindsight> PetefromTn_: don't let them manipulate you. I believe you. Who would make up such a story? :)
[17:18:14] <PetefromTn_> The machine is grey on the top area
[17:18:18] <archivist> and the garage http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_04_15_glass_trolley/IMG_1526.JPG
[17:18:23] <PetefromTn_> and all gunmetal grey on the bottom
[17:18:31] <archivist> not tidy!
[17:19:28] <PetefromTn_> Okay okay you got me beat LOL
[17:19:30] <PetefromTn_> :D
[17:19:50] <PetefromTn_> I just like to put my best foot forward when showing shop pictures is all
[17:20:06] <archivist> had to invert the frame to get it out
[17:20:08] <PetefromTn_> not trying to BS ya
[17:20:29] <PetefromTn_> CaptHindsight I assure you I am NOT making this up ;)
[17:21:09] <PetefromTn_> and to make it all even better I just ordered a brand new Air conditioning system for the house that will arrive here wednesday so I need to get this beotch cleaned up to make room for it until I can get it installed.
[17:22:10] <PetefromTn_> I swear that damn Uhaul trailer was awesome....
[17:22:42] <PetefromTn_> right up until we lowered the damn rear deck and tried to get the machine to slide over the large crossways ribs they were kind enough to put into its face
[17:22:55] <PetefromTn_> Damn foot of the machine caught on every single one of them
[17:23:03] <archivist> I need to make more space here for the machines
[17:23:13] <PetefromTn_> you never saw such a furious prybar fest
[17:23:51] <PetefromTn_> my old POS heavy duty engine crane was actually able to lift the whole machine off the deck just enough to get something very very thin under it
[17:24:20] <PetefromTn_> then it was lots of cranking with the come-a-long until it slid off onto the wood cribbage we setup under it.
[17:24:44] <PetefromTn_> once we got the damn thing off the trailer and could drive the truck and trailer out from underneath it it was not too bad really.
[17:24:58] <PetefromTn_> apparently when the machine is fully assembled it weighs about 3k lbs
[17:25:34] <PetefromTn_> mine is less of course since it is missing the Z balllscrew Z motor and spindle motor along with everything in the electronics enclosure that was not bolted down tight hehehe

[17:27:24] <archivist> it is like chess, you have to think a few moves ahead
[17:27:29] <PetefromTn_> it seems like that mopped on paint comes off real quick with mar hyde tal strip paint remover spray so that is a good news.
[17:27:41] <PetefromTn_> yes exactly and try to not do anything terribly stupid.
[17:28:29] <PetefromTn_> trying to decide if I should strip the whole freakin lathe down to bare metal and respray with some nice epoxy based industrial paint or just do the top area where they mopped it on.
[17:28:50] <PetefromTn_> The base is just gunmetal gray and the paint while greasy and grimy does not look too bad really.
[17:29:08] -!- ler_hydra has quit [Remote host closed the connection]
[17:29:25] <PetefromTn_> I may try to mask off the bottom area after I clean the piss out of it and just respray the top sheetmetal after I get it stripped.
[17:30:04] <PetefromTn_> Would have been nice to just get on with retrofitting it but I know how I am It would drive me nuckin' futz to have to look at all that mopped on paint for any amount of time really.
[17:31:35] <PetefromTn_> well I better get my ass back out there and get to cleaning and moving stuff so I can make room. I was thinking of putting it in the midle of the side wall so I can have access to the tailstock end for longer bar stock but I would need to move a couple tons of junk to make that happen.
[17:31:52] <PetefromTn_> We will see how determined I am I guess here haha

[19:40:35] <varesa> what is the most likely reason for the max speed I can run my machine without stalling suddenly dropping by 1/2?
[19:41:34] <varesa> the machine was also moved from around 0-10C to +20C, so maybe something temp-related in the drives causing current to drop?
[19:43:05] <varesa> I used to have my max velocity in the .ini around 20, now I need to put it and the homing velocities to something like 6 for some axes for it to even home
[19:43:09] <Tom_itx> bad bearing?
[19:43:11] <CaptHindsight> what drives? motors? type of machine? whay type of gearings?
[19:43:16] <Tom_itx> somthing binding
[19:43:18] <CaptHindsight> bearings?
[19:43:58] <varesa> I don't think it is a mechanical thing, as atleast the Z axis which propably has the most trouble moving up is really light if I spin it by hand when the motor is off
[19:44:06] <MrSunshine> hmm got blocks, 40x40mm big ... that i need to hold down firmly to make a hole in them using the cnc ... anyone got any idea? i need them to be fast swapable to continue on the next batch .. and atleast 5 - 10 blocks at a time in a jig =)
[19:44:14] <varesa> (unless it starts to bind at higher speeds)
[19:44:14] <CaptHindsight> was the machine moved or was the just ambient temperature changed?
[19:44:21] <varesa> CaptHindsight: moved
[19:44:25] <MrSunshine> (they do not have a perfect size ... can diff -1mm from the 40mm :/
[19:44:29] <Tom_itx> :(
[19:44:47] <CaptHindsight> varesa: maybe something is now more bent than it was
[19:45:23] <varesa> CaptHindsight: possibility, but then it moves just fine by hand making me think the motors are driven with lower current than before
[19:45:33] <CaptHindsight> wiring
[19:45:46] <CaptHindsight> loose solder connections
[19:46:20] <varesa> I don't really know about the models of the drives/motors/mechanics, it is this Terco CNC 45 with close to zero specs/documentation: I don't really
[19:46:24] <CaptHindsight> electrical contamination falling into wiring, contacts. relays etc
[19:46:36] <varesa> *: http://i.imgur.com/m6onk0k.jpg
[19:47:05] <CaptHindsight> I asked since the more info we have the better guesses we can make
[19:47:11] -!- hpopols [hpopols!4ef0e66d@gateway/web/freenode/ip.] has joined #linuxcnc
[19:47:19] <hpopols> Hi
[19:47:25] <varesa> Of course, and I'm more than happy to tell as much as I know
[19:47:40] <ReadError> varesa, QUIT STALKING ME
[19:48:06] <hpopols> I saw a small typo error in linuxcnc interface documentation, where can I report it?
[19:48:07] <varesa> ReadError: Stop being interested in the same things :p
[19:48:39] <CaptHindsight> hpopols: what typo?
[19:48:50] <varesa> I checked that the drives are receiving a steady 42V, doesn't drop/have ripple when an axis is run (atleast on the X axis, I assume they are being fed from the same supply. The others are harder to measure)
[19:49:08] <CaptHindsight> hpopols: have a link?
[19:49:09] <hpopols> In http://linuxcnc.org/docs/html/common/python-interface.html
[19:49:23] <hpopols> traj_mode(int) set trajectory mode. Mode is one of MODE_FREE, MODE_COORD, or MODE_TELEOP.
[19:49:43] <hpopols> it's TRAJ_MODE_FREE,...
[19:50:20] <hpopols> nothing very important but i notice it when witting my own gui
[19:51:24] <CaptHindsight> hpopols: near the end of section 5?
[19:51:48] <hpopols> yes end of 5.2
[19:51:58] <CaptHindsight> traj_mode(int) set trajectory mode. Mode is one of MODE_FREE, MODE_COORD, or MODE_TELEOP.
[19:52:16] <hpopols> yes, constant name doesn't exist
[19:52:30] <ReadError> varesa, what drives you using?
[19:52:40] <hpopols> real one are TRAJ_...
[19:53:42] <CaptHindsight> hpopols: so it should be the same as used in 3.1 " motion_type (returns integer) - trajectory planner mode. One of TRAJ_MODE_COORD, TRAJ_MODE_FREE, TRAJ_MODE_TELEOP."
[19:54:28] <hpopols> CaptHindsight: yes i think
[19:55:33] <CaptHindsight> "This is work in progress by Michael Haberler. " who has left to work on his fork of Linuxcnc
[19:55:39] <hpopols> CaptHindsight: MODE_* constant is used for AUTO MANUAL MDI
[19:56:13] <hpopols> mah left the lcnc project?
[19:56:44] <hpopols> i have been away for a while now but i didn't know that!
[19:56:57] <CaptHindsight> I used to see his nick in here but I think he left to pursue machinekit
[19:58:28] <hpopols> CaptHindsight: ok, i don't know this project
[20:02:52] <varesa> CaptHindsight: ReadError: My drives are 3x something that looks like this: http://i.imgur.com/bugM8Xz.jpg
[20:03:15] <ReadError> what do those pots do?
[20:03:25] <ReadError> current adjustment?
[20:04:11] -!- Sigmac has quit [Quit: Leaving]
[20:04:22] <varesa> ReadError: Haven't tried, I just took one out of the machine and removed the covers/heatsinks
[20:06:44] <CaptHindsight> varesa: any problems before you moved the machine?
[20:07:03] <CaptHindsight> and did the problems start the first time you tried to use it after the move?
[20:07:07] <varesa> CaptHindsight: not of this sort
[20:07:13] <varesa> CaptHindsight: pretty much yes
[20:08:19] <CaptHindsight> varesa: are the all motors the same? is it just the one axis that is slower now?
[20:09:15] <varesa> CaptHindsight: They could be, though atleast the Y motor is pretty well hidden/covered. X seems unaffected but Y and Z required slowing a lot
[20:09:31] <CaptHindsight> can you compare the resistance of the motor windings from one motor to the other if it's only one axis that has changed
[20:09:45] <CaptHindsight> so (2) two axis seem slower now?
[20:09:51] <varesa> yes
[20:10:02] <CaptHindsight> maybe power supply as well
[20:10:44] <CaptHindsight> is there a common power supply to all 3 drives? do they each have their own power supply?
[20:11:28] <varesa> CaptHindsight: Each of the drives have their own pair of cables coming from the power supply, but I need to move the machine to see where they actually connect
[20:13:16] <CaptHindsight> I'd check all the connections, tighten things back up. One of the first things we'd do is start looking for bad connections by tapping boards, harnesses etc to see if it changes anything
[20:13:20] <PetefromTn_> Well I couldn't stand it anymore. I started stripping that freakin' mopped on shitty paint job off the headstock and the spindle belt enclosure area.
[20:13:47] <PetefromTn_> I also found that I have most of the stuff to put the sheetmetal covers all back together.
[20:13:48] <cathode> <3 amazon. just got my stepped bit delivered... on a sunday
[20:13:59] <PetefromTn_> I found the cover for the X axis belt drive
[20:14:01] <cathode> i ordered on friday night
[20:14:01] <CaptHindsight> PetefromTn_: before you know it you'll have it all apart and media basting everything :)
[20:14:14] <PetefromTn_> I found the cover for the Apron area
[20:14:24] <CaptHindsight> cathode: carrier pigeon?
[20:14:26] <PetefromTn_> It has a nice long ballscrew cover
[20:14:26] <PetefromTn_> for the z
[20:14:48] <cathode> https://www.dropbox.com/s/sr7zdmaj6z9l83u/2014-10-26%2013.13.22.jpg?dl=0
[20:14:55] <cathode> USPS, apparently they deliver on sunday now
[20:14:58] <PetefromTn_> Captain I wish I had a parts washer big enough to dip this monster in so I could really clean it off.
[20:15:32] <CaptHindsight> varesa: chips, loose fasteners, etc also can find their way inside and fall onto connections
[20:15:44] <PetefromTn_> I figured out what some of the stuff in the belt drive compartment is.
[20:16:04] -!- gennro_ has quit [Ping timeout: 245 seconds]
[20:16:10] <PetefromTn_> It has apparenlty an oil recirculation pump that takes the headstock lubrication and sucks it out the bottom and then pumps it back up into the top somewhere
[20:16:30] <PetefromTn_> It has an encoder on the spindle
[20:16:47] <varesa> CaptHindsight: I'll check everything and do some more measurements
[20:17:00] <PetefromTn_> it has a coolant pump altho the pump itself is missing but the lines are already run in a nice jacketing looks like 220 single phase
[20:17:20] <PetefromTn_> It had an electronic one shot oiling system
[20:17:28] <varesa> I just now remembered that I did a lot of rewiring so I don't need the old controller box
[20:17:58] <PetefromTn_> the lines for it are run but the Z circuit is hanging there with what looks like a banjo bolt setup and I am not sure where the hell it goes.
[20:18:17] <cathode> PetefromTn_ - sounds like your machine is like my 1926 house
[20:18:32] <cathode> "i see this wire. and it's hot, but i have no idea where the hell it goes or comes from"
[20:18:37] <varesa> At first I moved just the power switch to the machine itself, didn't work. I realised that stuff like 5V and 12V supplies to the drive/logic stuff inside the machine are provided by the controller...
[20:18:43] <PetefromTn_> There is a pneumatic line going to an angled bit that was mounted on the toolpost for what I have no idea
[20:18:50] <PetefromTn_> cathode Yeah I know right.
[20:18:57] <PetefromTn_> Apparently the machine is a 1996
[20:19:02] <cathode> :/
[20:19:05] <PetefromTn_> it came with a three phase 7.5 HP spindle motor
[20:19:06] <cathode> made in taiwan/china?
[20:19:12] <PetefromTn_> no canada
[20:19:41] <PetefromTn_> its an HH Roberts Standard Modern 14x40
[20:19:50] <cathode> i bet once you get everything torn apart there will be a placard inside with the words "SORRY, MATE"

[20:40:06] <cathode> ah nvm it would need to be a brushless DC motor i guess. that would be ridiculously expensive
[20:41:00] <varesa> cathode: for the spindle?
[20:41:15] <cathode> i mean in general
[20:41:57] <varesa> mine has a DC spindle
[20:42:00] <cathode> i bought a 1hp 3-phase AC motor for my wood-cutting bandsaw that i'm building. but i'm thinking 1hp might be a little undersized so i'm looking at other options
[20:42:35] <varesa> ah that kind of machines
[20:43:17] <hpopols> CaptHindsight: I am curious, What is the purpose of the machinekit project? I went to the website nothing important related there. As far as i understood, the project is not only foccused on CNC and support embedded hardware (BagleBone). Not much changed from LCNC source. Can you tell me more about this project (few words)? Thank you in advance for your time.
[20:46:21] <cathode> i don't have 3phase service at my house, so i'm using a VFD with single-phase input to produce 3phase output. if i upgrade my motor size i'd like to still do the same thing but it's harder to find 3hp and 5hp VFD units that have a single-phase input option

[21:11:39] <cathode> PetefromTn_ - those are nice links to your computer's hard drive

[21:38:07] <somenewguy> unless of course they are in a catalog but not actually available, which is entirely possible, I am only window shopping
[21:38:18] <cathode> yeah i am running 240VAC to everything in my shop
[21:38:38] <somenewguy> yeah trying to get real power out of 110 just nets you fire

[22:00:44] <somenewguy> he released 1.0 a few months ago after years of silence
[22:00:50] <somenewguy> oooh sorry I'm thinking of heekscad/cam
[22:01:15] <somenewguy> I use freecad for modeling only, works well enough for me

[22:05:26] <somenewguy> freecad is much nicer than heekscad
