[00:03:12] <_methods> doesn't linuxcnc make g53/g54 the same by default?
[00:03:27] <_methods> when you home it sets that as g54 correct?
[00:05:00] <the> hi, i was getting confused myself, on my axis screen in the preview it shows G54, this it would appear is indeed the same as G53 - someone correct me if i am wrong...
[00:05:05] * JT-Shop thinks he needs to further subdivide the crimp on terminal collection
[00:05:43] <_methods> you can reset g54 to whatever
[00:06:11] <_methods> but i think they default when you home
[00:06:21] <_methods> to home position
[00:06:23] <JT-Shop> the: G53 is the machine coordinates
[00:06:30] <_methods> yes
[00:06:43] <_methods> but when you home i believe lcnc sets both g53 and g54
[00:06:50] <JT-Shop> G54 - G59.4 is coordinate systems you can apply offsets to
[00:06:52] <_methods> to the same coordinates
[00:07:04] -!- jdqx has quit [Ping timeout: 250 seconds]
[00:07:16] <JT-Shop> not really, if you have an offset from before in G54 it is still there
[00:07:27] <_methods> ahhhh
[00:07:35] <_methods> i did not know that
[00:07:50] <_methods> even when your first fire up a machine and home it?
[00:07:57] <JT-Shop> a good bed time story is the important user concepts in the manual
[00:08:14] <JT-Shop> offsets are stored in a file...
[00:08:22] <_methods> well alrighty then
[00:08:48] <_methods> good to know
[00:12:09] <JT-Shop> that's another reason a good preamble is needed

[00:17:00] <enleth> andypugh: did you have that gearbox casting made commercially or somehow made it yourself?
[00:18:02] <enleth> Tom_itx: is the kinda-sorta 30's vintage car look intentional?
[00:18:17] <JT-Shop> I could have used that today lol

[00:29:06] -!- Praesmeodymium has quit [Ping timeout: 240 seconds]
[00:30:22] <andypugh> enleth: I paid a foundry to make the casting from my own patterns.
[00:30:38] <the> JT-Shop, your od.ngc - what is final cut?
[00:31:27] <andypugh> the: I can’t remember what the home_offset means, but that will be your problem. Is it a shared home/limit switch?
[00:31:33] <the> JT-Shop, the cycle appears to work for me but stops at around half the required depth of final diameter...
[00:31:37] <JT-Shop> depth of last cut IIRC
[00:32:15] <the> andypugh, yes, only one limit swich on the z and one on the cross slide...
[00:32:51] <andypugh> You need the switch to be outside your axis limits then. So yo can’t jog on to it.
[00:33:05] <the> JT-Shop, that is what i thought. i cant get it to cut the full depth - any idea? does a certain number of passes and stops with the motor still going...
[00:34:03] <the> andypugh, ie a -minus value also?
[00:34:32] <andypugh> I can’t remember. It’s ages since I set up a new machine.
[00:34:49] <the> andypugh, i will try... cheers.
[00:36:19] <andypugh> Do you get the message after homing is complete but before you move? That indicates that the move-to-home isn’t moving off the switch.
[00:37:58] <the> andypugh, i get the message after homing is complete - everything moves in exactly the same way as it did originally.
[00:39:20] <andypugh> Your home position needs to be somewhere clear of the switch. Is your final homing move off of the switch or on to the switch?
[00:39:54] <andypugh> Have you read the homing page?
[00:40:36] -!- chris_99 has quit [Quit: Leaving]
[00:41:16] <andypugh> I am curious to see what this goes for, I intend to sell my home-converted mill/lathe at some point.
[00:41:19] <andypugh> http://www.ebay.co.uk/itm/151936433454
[00:41:33] <the> final homing move is off the switch. it finds the switch then trys to move much further than the possible movement of the cross slide...
[00:42:32] <andypugh> What’s your home position?
[00:43:05] <the> working - 40
[00:43:14] <the> not minus
[00:43:32] <andypugh> That’s all the way in
[00:43:43] <the> x, HOME = 40.0
[00:43:51] <andypugh> You don’t have a 40 any more...
[00:43:56] <the> at the very beginning of its travel...
[00:43:57] <archivist> andypugh, I had one of those mills as a manual, its junk as a mill, but a reasonable grill
[00:44:00] <archivist> drill
[00:44:34] <andypugh> If your max is 0 and your min is 40, then it can’t move to a home position of 40, can it?
[00:44:43] <andypugh> Sorry, min is -40
[00:45:17] -!- AR__ [AR__!~AR@24.238.81.234.res-cmts.sth2.ptd.net] has joined #linuxcnc
[00:46:18] <andypugh> The HOME_POSITION has to be somewhere between Min and Max
[00:46:22] <archivist> the round column is the main error in design
[00:47:03] <andypugh> I am not planning on bidding, I am just wondering if anyone actually pays money for scruffy home-conversions.
[00:47:18] <andypugh> (I think mine is a little better-looking than that one)
[00:47:32] <archivist> I would never expect you to get one of those :)
[00:48:02] <JT-Shop> you guys are burning the midnight oil tonight
[00:48:04] <archivist> I think its reserve is too high
[00:48:34] <andypugh> JT-Shop: It’s only a little past midnight
[00:48:51] <JT-Shop> I stayed up to midnight once
[00:49:01] <JT-Shop> well maybe twice
[00:49:02] <andypugh> archivist: Hmm, yes “Reserve not met”
[00:49:33] <andypugh> Not even on ballscrews.
[00:50:50] <andypugh> This is mine: https://picasaweb.google.com/108164504656404380542/CNCUnsorted#5611904480713910226 I have certainly become more ambitious in my conversions since that. Mainly my budget is about an order of magnitude higher.
[00:51:12] <archivist> andypugh, yet no bids yet on http://www.ebay.co.uk/itm/Adcock-Shipley-2AG-Horizontal-Milling-Machine-/181986608684
[00:51:41] <archivist> and no silly reserve
[00:51:47] <andypugh> Folk don’t realise that Horizontals are useful
[00:52:18] <archivist> and that is a good lump of iron
[00:52:59] <_methods> i'd rather have a horizontal personally
[00:53:20] <andypugh> Another problem for many folk. They can’t see how they would move it, or where they could put it. The Mach3 device would sit in a wood-floored shed. The Adcock and Shipley would fall through the floor of a shed.
[00:53:39] <andypugh> _methods: Having both is good.
[00:53:46] <_methods> oh of course
[00:53:58] <_methods> but if i had to pick one or the other i'd pick the horizontal
[00:54:39] <andypugh> _methods: I find the horizontal head useful for stuff that is way too big for the mill, like this: https://picasaweb.google.com/108164504656404380542/Holbrook#6231236737028424114
[00:54:56] <_methods> way more versatile
[00:55:03] <andypugh> I mean having a single machine with both heads
[00:55:04] <_methods> you just have to be more creative with your setups
[00:55:57] <andypugh> _methods: This is the same machine: https://picasaweb.google.com/108164504656404380542/Holbrook#6230479153726904034
[00:56:39] <_methods> yeah nice machine
[00:57:12] <_methods> i'm tryin to find a nice hardinge tm-um
[00:57:19] <_methods> for a reasonable price lol
[00:57:25] <archivist> I was abusing mine a bit http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_06_15_Adcock_Shipley/IMG_1249.JPG
[00:58:01] * malcom2073 kicks archivist's internet pipe
[00:58:01] <malcom2073> :P
[00:58:20] <_methods> now that's what i was talking about
[00:58:23] <_methods> gettin creative lol
[00:59:28] <_methods> some smartass put libreoffice in the lcnc iso
[00:59:47] <_methods> has that always been in there lol
[00:59:53] <andypugh> archivist: It ought to be trivial to fasten a high-speed Chinese spindle to the overarm for for engraving etc.
[01:00:28] <andypugh> _methods: It’s part of the Debian LiveCD. So more a case of the pacckage builder not removing it.
[01:00:47] <andypugh> You can remove it if you want. But do _not_ remove the calendar thingy.
[01:00:54] <_methods> hahah ok
[01:01:00] <_methods> i'll leave it i'm not hurting for space
[01:01:14] <_methods> i was just curious what was taking my install so long
[01:01:56] <andypugh> For some reason the entire GUI has a dependency on the calendar. If you uninstall that then do an autoremove you lose X ans GTK and have a text-only command-line machine.
[01:02:05] <andypugh> Don’t ask me how I know.
[01:02:20] <_methods> haha i think i remember you having that issue a month ago or so

[01:19:26] <the> and i think tomorrow i have to fix my nick, the just doesnt cut it...
[01:20:00] <andypugh> I think you just have to type /nick newname
[01:20:14] the is now known as thesaint
[01:20:17] <thesaint> lol..
[01:20:22] <Akex_> +1
[01:20:32] <thesaint> never did like irc...
[01:21:13] <thesaint> andypugh, didnt get it working but learnt lots, thanks for the help..
[01:21:37] <andypugh> You will get there. You just need to read, study and inwardly digest the homing manpage
[01:21:54] <Akex_> Andy How you choose the speed on your lathe ? With linuxcnc ?
[01:22:09] <Akex_> Spindle speed
[01:22:34] <andypugh> Which lathe?
[01:23:14] <Akex_> Maybe Is not the good words (spindle)
[01:23:37] <Akex_> The last picture
[01:24:09] <Akex_> Holbrook
[01:24:41] <andypugh> Ah, that is done with LinuxCNC, yes. There is only one VFD that either controls the mill spindle or the lathe spoindle. A relay swaps between the two (hard-coded in the HAL file for lathe or mill mode)
[01:24:42] <Akex_> I see you put a vfd or similar
[01:24:55] <andypugh> Ah, no, wait, the Holbrook?
[01:25:05] <thesaint> andypugh, going to read it now.... cheers.
[01:25:05] <andypugh> That is a work in progress.
[01:25:12] <Akex_> Yes
[01:25:45] <Akex_> Ok and on this lathe there are a gear box ?
[01:25:55] <andypugh> There is a 3hp motor in the base, with a variator, a gearbox _and_ a VFD. I still need to decide how the speed will be controlled. I _could_ put a servo on the variator.
[01:26:54] <andypugh> The motor in some of the photos is the Z servo, though it looks big enough to drive a spindle.
[01:27:06] <andypugh> (1kW)
[01:27:21] <Akex_> Ok, for you what Is a power for a good servo ?
[01:27:38] <Akex_> Power needed
[01:27:45] <andypugh> It depends on the application.
[01:27:47] Protractinium is now known as praesmeodymium
[01:28:02] praesmeodymium is now known as Praesmeodymium
[01:28:22] <Akex_> The good answer ;)
[01:28:27] -!- patrickarlt has quit [Remote host closed the connection]
[01:29:11] <Akex_> And you, for your lathe ?
[01:29:40] <andypugh> My stepper lathe is about 50W per axis, and works fine. The Holbrook will be 1kW on Z and 600W on X, and I fully expect not to be working the motors even slightly hard.
[01:30:07] <andypugh> I am largely using motors that I had lying about that turned up cheap on eBay
[01:30:25] <Akex_> I speak for spindle
[01:31:41] <andypugh> 1.0kW is OK on my stepper lathe. I expect the 2.2kW on the Holbrook to be better. Commercial CNC lathes tend to be 7kW or more.
[01:32:08] <Akex_> I have a lathe but i don t know if i install linuxcnc or just a dro
[01:32:10] <andypugh> Lots of mid-sized manual lathes like the Myford are 1hp
[01:32:36] <Akex_> 7kw Is not cheap no ?
[01:32:58] <andypugh> No, and is difficult on a domestic power supply.
[01:33:27] <Akex_> I have 32A and 380v
[01:34:00] <andypugh> Anyway, I have to log off now. But it sounds like you can run a proper industrial machine.

[08:52:07] <trentster> hey all
[08:54:01] <trentster> I am busy with the re-design of my Z axis for linear profile rails - I was wondering on opinions where is best location for screw holes from bearing plate to attach to ballscrew nut? as per this screenshot https://monosnap.com/file/v1m3SMKe4WtkIkSZSMfzzg5RwhB1gR.png
[08:56:33] <archivist> did you forget the carriages
[09:01:03] <trentster> nah they are not in the diagram yet, they are those small schneebergers the 9mm gap is for them
[09:05:02] <trentster> archivist: https://monosnap.com/file/KzwD2pmSkYOJOPKiThNkeoi7ojutWF.png thats what the ballscrew mount looks like
[09:05:18] <trentster> does it matter if the bearing plate is attached in the middle or at the top edge?
[09:06:18] <archivist> working to a thou, dont care
[09:07:02] <archivist> when working to tenths you start to worry about thermal expansion etc
[09:09:40] <trentster> archivist: so if you did care about thermal expansion where would the best place to conenct it be?

[16:13:11] <ssi> quiet today!
[16:14:05] <morbo> any recommendations for a pololu-style or even same pinout stepper driver rated for more more than 2 amps without cooling? supposedly the DRV8825 can do it with cooling, but that's not an option for me. :(

[16:15:38] <morbo> any heatsink suggestions then
[16:16:08] <archivist> could even be the case you put it into
[16:16:23] <morbo> thats a little further down the road.
[16:16:30] <archivist> many drivers come with a heatsink
[16:16:57] <morbo> they come with pretty small ones sometimes
[16:17:15] <archivist> eg the black box style
[16:17:20] -!- justanotheruser has quit [Ping timeout: 260 seconds]
[16:17:34] <morbo> do you have a suggestion on a driver?
[16:17:34] <archivist> the others I dont trust
[16:17:37] <CaptHindsight> convection vs forced convection, convection is just the use of a heat spreader
[16:17:49] <CaptHindsight> forced convection is a heat spreader with a fan
[16:18:14] <CaptHindsight> you can do the same with convection only you require more surface area
[16:18:18] <archivist> the bigger the fins the less fan needed
[16:19:24] <archivist> my driver I have been messing about with the last few weeks hardly gets warm
[16:19:52] <morbo> I'd like to use 2amp zapp steppers
[16:20:14] <CaptHindsight> the problem with the A4988 is that they designed the package to cool the die via the pins and not the case
[16:20:19] <morbo> but I can't seem to find some drivers that a like pololus that can handle it.
[16:20:32] <morbo> without dealing with cooling and et
[16:20:33] <morbo> c
[16:20:41] <morbo> any driver suggestions in general, for around 2amps?

[16:21:54] <archivist> first I see on ebay http://www.ebay.co.uk/itm/CNC-Microstep-Stepper-Motor-Driver-2M542-4-2A-Controller-24-50V-DC-Nema17-23-34-/121673528376

[16:22:21] <CaptHindsight> the DRV8825 package uses an exposed pad to remove heat from the device
[16:23:13] <CaptHindsight> so both require some fancy pcb layout to move the heat from the pcb out to a heatsink

[16:23:46] <trentster> Anyone ever mount 15mm Hiwin rail to 30 series extrusion - the bloody screws are M3 - know any clever way to do it?

[16:25:57] <trentster> archivist 30mm metric
[16:26:03] <archivist> trentster, I thought that was 4mm

[16:29:01] <archivist> use 3.5mm screws then
[16:29:29] <trentster> that still does not solve my problem
[16:29:40] <trentster> How to mount rail on the 30 series extrusion
[16:30:01] <archivist> t nuts or use something solid and not that extrusion
[16:30:06] <CaptHindsight> he needs some matching nuts
[16:30:06] <trentster> besides making t-nuts which is a non-option for em I dont have a machine that can cut steel
[16:30:30] <CaptHindsight> make em from aluminum
[16:30:52] <CaptHindsight> or bolt the rails to some plate and then bolt the plate to the t-slot
[16:30:59] <archivist> make sure your nuts have as much thread as possible
[16:31:26] <trentster> the issue with aluminium tnuts is the thread can strip really easily

[16:34:28] <CaptHindsight> or find some steel flats 12-15mm wide and 2mm thick
[16:34:48] <CaptHindsight> drill and tap, cut with a hacksaw
[16:34:54] <archivist> steel 1/2" thick and throw the extrusion

[16:35:52] <trentster> CaptHindsight: yeah thats a good idea, even 4mm thick would work

[16:43:53] <CaptHindsight> use the rails as a drill guide, well for marking anyway
[16:43:56] <trentster> and hope I can get every single hole just perfectly centered without a cnc machine - yikes!
[16:44:39] <CaptHindsight> you'll have a little play in the holes and with the length of the screws
[16:45:09] <CaptHindsight> you have to learn somehow
[16:45:38] <archivist> I clamped one rail made sure it was square then marked through the holes, mounted that one and then used the carriages and plate to set the width for the second rail
[16:45:46] <CaptHindsight> then when you're done you'll know how to do it better next time
[16:46:20] <trentster> No pain no gain - huh guys ;-)
[16:46:35] <archivist> I drilled an mounted one screq for the second rail, moved the carrage to the other end for the second screw
[16:47:12] <archivist> used that to make sure it was parallel

[21:02:58] <andypugh> Well bother! (quoth he, surprisingly mildly) my lathe drivetrain just seized solid.
[21:03:52] <thesaint> guys, does anyone know on the preview screen in axis if you can change the number of decimal places shown on your intended cuts? I have only one order of precision, i would like 3.. cheers!
[21:04:32] <thesaint> andypugh, hi andy, sorry to hear!
[21:04:55] <thesaint> that sounds bad..
[21:04:57] <andypugh> Only one? You should have 2 in metric and 3 in imperial.
[21:05:16] <anomynous> why metrics get less than imperials?
[21:05:19] <thesaint> only one.. ie 12.4 etc...
[21:05:28] <andypugh> That’s very odd.
[21:05:32] <cradek> I don't understand "on your intended cuts"
[21:05:49] <cradek> can you say more precisely, or make a screenshot?
[21:05:52] <thesaint> cradek, preview of what the tool will do..
[21:06:13] <andypugh> Ah, you mean the extents? I thought you meant the DRO

[21:06:49] <thesaint> is that called the extents? thanks..
[21:07:05] <thesaint> the stuff shown in red before you hit start...
[21:07:11] <cradek> did you know you can click on those lines, and it takes you to the corresponding line in the gcode program? that's often an easy way to see the exact values in the corresponding code

[21:09:01] <thesaint> cradek, cool..
[21:09:21] <andypugh> You probably can change the precision of the extents.
[21:09:32] <thesaint> andypugh, where do i do that?
[21:09:39] <andypugh> I have no idea
[21:09:50] <andypugh> I know that you can change the DRO precision
[21:10:07] <cradek> I believe you can't change either without editing the source
[21:10:14] <thesaint> ok, i use google and see what i come up with, cheers!
[21:10:22] <thesaint> i know what to look for now..
[21:10:30] <andypugh> Indeed, though as they are interpreted files, there is no need to recompile
[21:10:45] <jdh> I'd like another digit myself
[21:11:11] <andypugh> DRO or extents?
[21:11:28] <jdh> extent
[21:12:35] <jdh> I put the cutter where I want it and touch off to extent
[21:14:45] -!- swarfer has quit [Quit: swarfer]
[21:14:54] <jdh> but, I know it is .0625 not the displayed .062
[21:16:49] <andypugh> Are you sure you don’t mean DRO? I know how to tweak the DRO precison (edit around line 1321 of /usr/lib/pymodules/pythin2.7/glcanon.py)
[21:17:17] <andypugh> By extension, it looks like you need to edit line 567 of the same file to change the extents display
[21:21:12] <andypugh> Yes, that works: http://imagebin.ca/v/2TFBHtnvZkNh
[21:22:06] <thesaint> yes, looking at it now, i dont seem to have file glcanon.py - at least not where you said..
[21:22:55] <andypugh> You will need to use “gksudo gedit” to be allowed to edit the file.
[21:23:29] <andypugh> And I can never type “Python” which is part of the problem.
[21:23:57] <thesaint> lol... still cant find it :-)
[21:23:58] <andypugh> “locate glcanon.py” will find your version
[21:24:03] <thesaint> doing..
[21:24:39] <andypugh> I have three of them, which is interesting
[21:24:49] <thesaint> my linux admin skills are very rusty, i have 2 of them..
[21:24:56] <andypugh> Two I can understand, three is a surprise
[21:25:24] <andypugh> I edited the one in usr/lib/pymodules and it worked

[23:40:01] <CaptHindsight> looking for a motor speed controller that has velocity mode, adjustable ramp up/down and digital readout, you'd think that this would be easy to find turnkey
[23:41:49] <FloppyDisk> what kind of motor? Like an ac motor or dc brushed? You can try www.kbelectronics.com. They might have something.
[23:42:21] <CaptHindsight> doesn't matter +-10V out, looking for the control vs the drive
[23:42:25] <FloppyDisk> Thinking outloud, I don't recall a stepper motor or servo drive that would do that. But a VFD...
[23:43:21] <FloppyDisk> Oh - you're looking for a pot w/ +-10vdc output to run your drive.
[23:44:05] <CaptHindsight> digital pot with settable velocity and ramp up/down
[23:45:24] <CaptHindsight> might be a AC servo, BLDC or mini brushed DC motor
[23:45:56] <FloppyDisk> I did a little googling and arduino comes up... Or this type of thing: http://lechacal.com/wiki/index.php/Stepper_control_generic
[23:46:03] <FloppyDisk> But, not really what you're looking for.
[23:46:23] <CaptHindsight> mope, you'd have to write the GUI and also wrote the ramping
