[00:13:22] <Tom_itx> andypugh you don't think if i thread the pulley it will cut the belt?
[00:13:40] <Tom_itx> (put the setscrew in the pulley part)
[00:14:17] <zeeshan|2> no
[00:14:22] <zeeshan|2> thats a common way to hoild pulleys to shafts
[00:14:26] <zeeshan|2> theyre chamfered through
[00:14:56] <zeeshan|2> unless im intrepreting that q wrong :/
[00:15:04] <Tom_itx> i may do that to lower them on the shafts
[00:15:22] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/cnc/new_pulleys/spindle_enc1.jpg
[00:15:23] <zeeshan|2> Tom_itx: does it work?
[00:15:25] <zeeshan|2> your current setup
[00:15:26] <Tom_itx> cut the shoulder off
[00:15:32] <Tom_itx> i haven't wired it up yet
[00:15:36] <Tom_itx> i just got it mounted
[00:15:44] <Tom_itx> the old one worked
[00:15:46] <zeeshan|2> what size shaft does the encoder have?
[00:15:55] <Tom_itx> .156
[00:16:01] <Tom_itx> i had to make a bushing for it
[00:16:11] <zeeshan|2> that might sound silly
[00:16:19] <zeeshan|2> but cant you just flip both pulleys upside down
[00:16:23] <zeeshan|2> to lower the belt
[00:16:24] <Tom_itx> no
[00:16:32] <Tom_itx> the shaft isn't long enough
[00:16:34] <Tom_itx> on either one
[00:16:53] <zeeshan|2> it looks so good as is
[00:16:59] <zeeshan|2> id wait till that encoder blows up
[00:17:04] <zeeshan|2> till coming up with another method :P
[00:17:07] <zeeshan|2> (it wont blow up)
[00:17:12] <Tom_itx> i have 3 more
[00:17:19] <zeeshan|2> doesnt look like the belt has much tension
[00:17:22] <Tom_itx> no
[00:17:24] <zeeshan|2> so youre not owning the bearings
[00:17:30] <Tom_itx> just enough to keep it from slipping
[00:17:56] <zeeshan|2> and to be honest
[00:18:01] <zeeshan|2> if the belt was tensioned really tight
[00:18:06] <zeeshan|2> i bet that angle would flex :P
[00:18:14] <Tom_itx> it would
[00:18:17] <Tom_itx> it's pretty thin
[00:18:49] <zeeshan|2> i wish i could mount an encoder like that
[00:19:29] <zeeshan|2> http://www.ebay.com/itm/251321358155?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[00:19:31] <zeeshan|2> i bought 3 of these
[00:19:31] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/cnc/new_pulleys/new_pulley_mounted3.jpg
[00:19:41] <Tom_itx> i just took the spacer out and flipped the angle around
[00:19:45] <Tom_itx> from the old one
[00:19:46] <zeeshan|2> rofl
[00:19:47] <zeeshan|2> nice
[00:20:00] <Tom_itx> lowered it a bit
[00:20:02] <zeeshan|2> did you make that pcb?
[00:20:07] <Tom_itx> no
[00:20:10] <Tom_itx> that's from a printer
[00:20:14] <zeeshan|2> ah
[00:20:14] <Tom_itx> so is the encoder
[00:20:44] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/motors/stepper6.jpg
[00:20:48] <Tom_itx> original purpose
[00:20:54] <zeeshan|2> nice
[00:21:17] <Tom_itx> the new one is better i think
[00:21:38] <Tom_itx> i'll have to edit the hal a bit
[00:21:59] <Tom_itx> add an index channel and adjust the CPR
[00:22:26] <Tom_itx> next i'll have to figure a way to hack the speed control and add a relay for reverse

[00:43:50] <andypugh> zeeshan|2: For some reason YouTube is broken on my PC at the moment so I can’t find the timestamp, but I used sensors like that and a top-hat shapd pulley on mu Mini-mill:
https://www.youtube.com/watch?v=ZhICrb0Tbn4&list=UUexvgsGz_QFvOublovDYoTQ
[00:45:09] <zeeshan|2> nice
[00:45:11] <zeeshan|2> where did you buy those
[00:45:15] <zeeshan|2> i feel like i paid too much for the 3 i bought
[00:45:37] <zeeshan|2> do they have a schmit trigger in em?
[00:46:23] <andypugh> I can’t remember, it was a long time ago.
[00:46:26] <Tom_itx> you can get em from china
[00:46:30] <Tom_itx> like mine?
[00:46:45] <zeeshan|2> no Tom_itx
[00:46:47] <zeeshan|2> the slot type
[00:46:49] <zeeshan|2> right angle style
[00:46:51] <Tom_itx> oh ok
[00:47:05] <zeeshan|2> andypugh: howd you position a and b phase?

[00:47:19] <andypugh> slotted holes
[00:47:23] <zeeshan|2> no
[00:47:27] <zeeshan|2> i mean physical sensor relative to each other
[00:47:33] <zeeshan|2> to bring em 90 deg apart
[00:47:45] <andypugh> slotted holes
[00:47:58] * zeeshan|2 slaps himself
[00:47:59] <andypugh> (and halscope)
[00:48:07] <zeeshan|2> i thought you were talking about about the trigger wheel :P
[00:48:17] <Tom_itx> andypugh i wonder how well that would work with a stepper
[00:48:26] <zeeshan|2> looks great btw
[00:48:29] <Tom_itx> with encoder feedback
[00:49:24] <andypugh> Gah! The web page I found on how to stop YouTube crashing Safari crashed Safari!
[00:49:35] <Tom_itx> hah

[00:51:51] <PCW> zeeshan|2: I think you may be making a mistake with the spindle encoder,
[00:51:53] <PCW> this should wire to a hardware encoder input, not field I/O so should have 5V or TTL signal levels
[00:51:54] <PCW> not high level PNP or NPN type signals
[00:52:17] <zeeshan|2> PCW: these will be wired to the encoder inputs
[00:52:29] <zeeshan|2> hm
[00:53:30] <zeeshan|2> http://www.clrwtr.com/PDF/SUNX/SUNX-PM-Series-Photoelectric-Sensors.pdf
[00:53:34] <zeeshan|2> on page 4
[00:53:53] <zeeshan|2> says output "PNP open-collector transistor"
[00:54:11] <zeeshan|2> so that is the wrong type? :/
[00:54:30] <Tom_itx> you want it to pull up or down when active?
[00:54:39] <zeeshan|2> well i thought it was pull down
[00:54:48] <PCW> Its OK, you wll have to add a pulldown resistor to the 7I77 inputs
[00:54:49] <Tom_itx> NPN then i think
[00:54:54] <zeeshan|2> but hes right, i was thinking of putting it to field i/o
[00:55:19] <Tom_itx> i hope i don't have to redo my bit file for the spindle encoder now...
[00:56:05] * zeeshan|2 reads 7i77 pdf
[00:57:03] <Tom_itx> PCW have you come across anybody trying to control a sherline spindle with the stock control and a mesa card?
[00:57:06] <zeeshan|2> the encoder inputs arent pull down inputs?|
[00:57:22] <Tom_itx> i wonder if i could unhook the pot and add some sort of interface there
[00:57:45] <PCW> No, they pullup in TTL mode
[00:57:59] <zeeshan|2> son of a
[00:58:04] <zeeshan|2> so i needed to buy pnp not NPN
[00:58:05] <zeeshan|2> er
[00:58:07] -!- BellinganRoy has quit [Quit: Konversation terminated!]
[00:58:07] <zeeshan|2> NPN nor PNP
[00:58:15] <zeeshan|2> those are way more common too!!!
[00:58:17] <Tom_itx> that's what i was thinking
[00:58:19] <zeeshan|2> fak
[00:58:28] <zeeshan|2> haha
[00:58:30] <Tom_itx> or add an inverter :D
[00:58:59] <Tom_itx> what are you switching?
[00:59:14] <zeeshan|2> Tom_itx: whatcha mean
[00:59:23] <PCW> or a 200 Ohm pulldown resistor/input
[00:59:24] -!- md-2 has quit [Read error: No route to host]
[00:59:25] <Tom_itx> what's the NPN hook to?
[00:59:25] <zeeshan|2> im hooking up the encoder signals directly to encoder input of 7i77
[00:59:32] <Tom_itx> oh ok
[00:59:39] <zeeshan|2> but field i/o is pull down
[00:59:42] <Tom_itx> nevermind, what i was thinking wouldn't work
[00:59:44] <zeeshan|2> and encoder input is pull up
[00:59:47] <zeeshan|2> damn it!
[01:00:23] <zeeshan|2> when someone finds this machine in 1000 years
[01:00:31] <zeeshan|2> they're gonna be so pissed off that i used a pnp encoder
[01:00:32] <PCW> its meant to work with open collector encoders (which always pull down = NPN)
[01:00:56] <Tom_itx> so you add pullups to the encoders?
[01:01:01] <zeeshan|2> pull down resistors
[01:01:04] <Tom_itx> to ensure they switch...
[01:01:05] <zeeshan|2> er
[01:01:11] * zeeshan|2 doesnt know anything anymore
[01:01:14] <Tom_itx> that's what i gotta to with this one
[01:01:29] <zeeshan|2> pcw whats wrong with wiring em to the field i/o? :-)
[01:01:33] <Tom_itx> but i already knew they were open collector
[01:01:38] <PCW> need to add pulldowns, the PNP opto pulls up
[01:02:01] <zeeshan|2> its too slow?
[01:02:16] <PCW> only problem with field I/O is that its only read at the servo thread rate
[01:02:28] <zeeshan|2> so theyre suseptible to jitter issues
[01:02:30] <PCW> (so nominally 1 KHz)
[01:02:50] <zeeshan|2> well thats 60000 rpm
[01:02:55] <zeeshan|2> this is 1:!
[01:02:57] <zeeshan|2> 1:1
[01:03:14] <zeeshan|2> i think my spindle hits a max of 5000 rpm
[01:03:26] <PCW> so with margin this would limit your max count rate to 500 Hz
[01:03:50] <zeeshan|2> 30000 rpm good enough! :)
[01:03:53] <PCW> so thats like 2 /3 slots at 5000 RPM
[01:05:10] <PCW> not very good, now you can use a higher res encoder if you only care about it at low speeds (say for tapping)
[01:05:23] <zeeshan|2> or just add pull down resistors
[01:05:27] <zeeshan|2> you said they need to be 200 ohm?
[01:05:42] <renesis> pullsups, no? non open collector?
[01:05:48] <renesis> *npn
[01:05:51] <zeeshan|2> its PNP
[01:05:54] <renesis> oh
[01:06:12] <zeeshan|2> so opto output -> 7i77 pin encoder A for example
[01:06:12] <renesis> this is still your gearshift encoders?
[01:06:23] <zeeshan|2> then encoder A -> 200 ohm resistor to ground?
[01:06:29] <PCW> The encoder inputs have 2K pullups so 200 Ohms would pull pretty close to ground
[01:06:39] <renesis> 200R, nice
[01:06:52] <renesis> that pulldown not fuckin around
[01:07:16] <renesis> oh
[01:07:20] <zeeshan|2> is my logic right?
[01:07:21] <zeeshan|2> about the wiring
[01:07:28] <PCW> and your optos can drive 50 mA so this is 25 mA
[01:07:28] <zeeshan|2> 200ohm to ground from the encoder input
[01:08:08] <PCW> Another option is to use one of the MPG inputs on the field I/O
[01:08:33] <zeeshan|2> from what i recall
[01:08:36] <zeeshan|2> thats inputs 16-20
[01:09:08] <zeeshan|2> nm
[01:09:10] <zeeshan|2> 16-19..
[01:09:20] <PCW> yes there are 2 channels (0=16,17, 1= 18,19)
[01:10:15] <PCW> these do not have a real index but I'm pretty sure the driver can simulate an index
[01:10:25] <zeeshan|2> ill use the pull down option
[01:10:27] <zeeshan|2> itll be easier
[01:10:35] <zeeshan|2> cause otherwise ill need to provide one of the vfields with 5v
[01:10:41] <zeeshan|2> and can't use that on board jumper anymore
[01:11:11] <PCW> you can use 24V signals into the MPG inputs
[01:11:33] <zeeshan|2> oh i just realized
[01:11:36] <zeeshan|2> this sensor doesnt need to be at 5v
[01:11:40] <zeeshan|2> its 5-24v
[01:11:44] <zeeshan|2> +/- 10%
[01:12:28] <zeeshan|2> (i was thinking the sensor can only work at 5v)
[01:12:32] <PCW> I suspect the real encoder input will be better/less trouble
[01:12:44] <zeeshan|2> okay pull down resistor it is
[01:13:10] <zeeshan|2> i mean each encoder input set
[01:13:12] <zeeshan|2> has a ground already there
[01:13:20] <zeeshan|2> itll be fairly easy to jumper a resistor between the pins
[01:13:40] <PCW> or at the OPTO

[01:23:44] <humble_sea_bass> I use my estop as a coat hook

[01:30:43] * zeeshan|2 hides
[01:30:51] <LeelooMinai> Like Chuck NOrris
[01:31:03] <zeeshan|2> you have a drill press
[01:31:05] <zeeshan|2> do you have holesaws?
[01:31:10] <zeeshan|2> ez to drill holes
[01:31:29] <LeelooMinai> I do not worry about making holes - I already made two for fan and intake:)
[01:31:45] <zeeshan|2> so whats the problem
[01:31:48] <zeeshan|2> make a hole in the door
[01:31:50] <zeeshan|2> less irc
[01:31:52] <zeeshan|2> :-)
[01:32:03] <LeelooMinai> But, the hole would be on the front door and kind of big - so that the whole button sticks out of it
[01:32:12] <zeeshan|2> what
[01:32:20] <zeeshan|2> its like a 22mm hole?
[01:32:27] <zeeshan|2> arent your fan holes bigger?
[01:32:27] <LeelooMinai> Because if I attach button to the door directly, I will have crazy mains cables going over the 7i76:)
[01:32:30] <zeeshan|2> like 102mm?
[01:32:41] <LeelooMinai> No, I put small 70mm fan in there
[01:33:10] <zeeshan|2> your e-stop has mains wires going through it?
[01:33:25] <LeelooMinai> Well, I could also make smaller hole, but then I would need to unscrew the red cup every time I want to open the door:)
[01:33:49] <LeelooMinai> zeeshan|2: Isn't that the point of it? To cut off power?
[01:34:03] <zeeshan|2> how many amps go through your main?
[01:34:22] <LeelooMinai> It's just psu for stepper drivers - not much
[01:34:30] <zeeshan|2> ah oka
[01:34:40] <zeeshan|2> usually you use contactors to kill main power
[01:34:43] <zeeshan|2> not an e-stop :p
[01:34:56] <zeeshan|2> e-stop uses NC coils on the contactor
[01:35:16] <LeelooMinai> Well, it's rated for far more than that psu can handle

[15:15:35] <taiden> hey all
[15:16:00] <taiden> i'm interested in running my linuxcnc computer from my windows computer
[15:16:16] <taiden> i do all my cad/cam on my windows laptop but i'd like to be able to control the linuxcnc computer directly from it
[15:16:20] <taiden> is there a good way to do this?
[15:16:44] <taiden> also would be nice to not have a keyboard, mouse, monitor dedicated to this thing
[15:20:21] <JT-Shop> is the linuxcnc computer in another room or building?
[15:21:25] <Tom_itx> JT-Shop what you workin on today?
[15:22:35] <Tom_itx> taiden probably not the best idea for realtime hardware
[15:23:05] <JT-Shop> a chimney cap for an outdoor fireplace
[15:23:40] <taiden> i had seen people get 1/3 latency by running headless
[15:23:51] <taiden> i thought it might show a performance increase as well

[15:24:13] <CaptHindsight> taiden: in the old days or much older hardware
[15:24:29] <taiden> estop is hardware on the gecko g540
[15:25:18] <taiden> perhaps its just more trouble than it's worth

[15:54:32] <JT-Shop> only if you can't boot the CD
[15:55:10] <Tom_itx> i wanted to try it on my old backup pc and it had problems with 10.04
[15:55:16] <JT-Shop> if I understand correctly the hot fix was for a few computers that could not boot from the USB or something like that

[16:44:34] <pcw_home> Its well to remember that the latency test doesn't actually do anything (no I/O, no memory allocation for RT tasks)
[16:44:36] <pcw_home> so a few usec here or there are basically meaningless
[16:47:27] <pcw_home> I suspect a J1800 will generate a much better step stream than a for example

[17:13:37] <Tom_itx> i really didn't find any cause yet
[17:14:13] <taiden> wait, the parallel port 7i43 is only $80?
[17:14:15] <Tom_itx> i need to sift thru the wires to see if anything came unhooked
[17:14:32] <Tom_itx> yeah but there's a cheaper better replacement with more io
[17:14:45] <taiden> what do you suggest?
[17:14:53] <Tom_itx> pcw_home what's that new card PN?
[17:14:55] <Tom_itx> i forget...
[17:15:01] <taiden> the mesa hardware is very daunting at first look
[17:15:01] <Tom_itx> with the 3 headers
[17:15:10] <taiden> just trying to get a better grasp of what you guys like to use
[17:15:17] <Tom_itx> mesa is it
[17:15:32] <taiden> yeah but what specifically
[17:15:32] <Tom_itx> 5i25 unless you need parport
[17:15:42] <Tom_itx> with a daughter card
[17:16:18] <pcw_home> for parallel port connection the 7I90HD is cheapest
[17:16:18] <taiden> with the 7i43 do you need anything else to run stepper motors?
[17:16:43] <Tom_itx> some sort of isolation for safety
[17:16:44] <taiden> 7i90 is $60 lol so cheap

[17:20:30] <t12_> anyone know what series of pins these are
[17:20:32] <Tom_itx> taiden i'm using the gecko 203v
[17:20:32] <t12_> http://dodeca-t.com/photos/20141122-20141122-_B222623.jpg
[17:20:39] <pcw_home> yes though a 5I25/6i25/7I80DB/7I92 is easier
[17:20:42] <taiden> almost seems pointless to run software stepping
[17:21:15] <Tom_itx> 5i25 would be a good choice
[17:21:32] <Tom_itx> with whatever daughter card you need with it
[17:21:47] <taiden> what are the daughter cards used for?
[17:22:08] <Tom_itx> all sorts of things
[17:23:07] <taiden> their stuff is completley insane
[17:23:18] <taiden> do you need a daughtercard to run stepper drives?
[17:24:40] <Tom_itx> probably not
[17:24:49] <Tom_itx> if your driver is opto isolated
[17:25:11] <taiden> and what kind of step frequencies would i see on these things?
[17:25:40] <pcw_home> 1/4 Clock low is max
[17:25:58] <taiden> sorry i'm not that well versed in computer systems
[17:26:06] <taiden> i'm just a lowly mechanical engineering student :P
[17:26:24] <pcw_home> so 8 .33 Mhz on a 5I25, 25 MHz on a 7I90
[17:26:40] <taiden> so 5 Mhz minimum across the board

[17:40:07] <Tom_itx> hmm
[17:40:16] <Tom_itx> wonder why it blew
[17:40:28] <Tom_itx> the problem i think came from something on the 7i47
[17:40:35] <pcw_home> 5V >7V
[17:40:50] <Tom_itx> or shorting the 5v?
[17:41:01] <Tom_itx> that's all i can see so far but can't see where
[17:42:12] <pcw_home> shorting the 5V (to gnd) would not hurt

[19:36:16] <CaptHindsight> there are differences in the same types of acrylics, it's actually a wide range of variations
[19:37:48] <PetefromTn_> I am making a neat edge lit sign for my wife's favorite musical band for her and I wanted to get some thicker acrylic clear sheet to get a good light transmission and the most pro look to it. Thinking like 3/8" think plate
[19:38:08] <CaptHindsight> either will work at that thickness
[19:38:57] <CaptHindsight> sheet is usually extruded
[19:39:19] <PetefromTn_> is sheet acrylic generally what is used for this application?
[19:39:55] <PetefromTn_> http://www.signsalive.net/edge-lit-signs/led-edge-lit-custom-sign.jpg wanting something like this.
[19:40:26] <XXCoder> PetefromTn_: can you get samples of both
[19:40:31] <PetefromTn_> http://www.outdoor-signs.co.uk/images/edgelit/edge_lit_etched_acrylic.jpg or this
[19:40:33] <XXCoder> then cnc both to same whatever
[19:40:37] <XXCoder> then test?
[19:40:56] <PetefromTn_> well money is tight right now so I just need to order what I need to complete the project
[19:41:12] <PetefromTn_> I am going to order enough to do two of them just in case I screw the pooch with the first one somehow
[19:41:25] <XXCoder> companies sometimes do send small free sample
[19:41:43] <XXCoder> but tend to only for if youre planning big project
[19:41:46] <CaptHindsight> heh, yeah around 2x2 inches
[19:41:57] <XXCoder> CaptHindsight: yeah. good enough to test light properies
[19:42:33] <PetefromTn_> not worried about that but just want to get a good material sheet ordered here.
[19:43:00] <PetefromTn_> reading that tho it seems cast acrylic may be the way to go
[19:43:05] <CaptHindsight> Home Depot
[19:43:21] <PetefromTn_> went to HD and their prices are stupid
[19:43:37] <CaptHindsight> extruded will have extrusion patterns

[19:44:27] -!- sumpfralle [sumpfralle!~lars@vmd6311.contabo.host] has joined #linuxcnc
[19:45:47] <PetefromTn_> sounds like extruded acrylic is more dimensionally accurate than cast and the flame polishing of the edges is better with extruded too... so maybe I will get some 3/8 extruded
[19:46:15] <XXCoder> like I said, get samples and test
[19:46:25] <XXCoder> see what results in better mini sign
[19:46:36] <XXCoder> then order larger ones for project

[21:00:35] <LeelooMinai> Hmm, strange - my axis moves 20mm instead of 10
[21:02:33] <LeelooMinai> I have set the driver to 1600 pulses/rev
[21:02:48] <LeelooMinai> ballscrew is 5mm per rev
[21:03:07] <LeelooMinai> And entered 320 for step_scale
[21:03:24] <LeelooMinai> 1600 / 5 being 320
[21:04:42] <LeelooMinai> Though I am not sure why the driver has this 1600 pulse/rev - it depends on the stepper...

[21:05:45] <archivist> just a factor of 2 error so adjust accordingly
[21:06:16] <LeelooMinai> Yes, but I would like to understand what is going on. Here's the table of my driver:
http://i.imgur.com/GLDdxxx.png
[21:06:28] <LeelooMinai> I have "normal" 200 steps per rev steppers
[21:07:44] <renesis> mine are 200 steps, so definitely "normal"
[21:07:54] <LeelooMinai> Right, 1.8 deg per step
[21:08:08] <renesis> pi/100
[21:08:09] -!- swingley has quit [Remote host closed the connection]
[21:08:23] <renesis> they step in centipi
[21:08:32] <LeelooMinai> Unless I somehow misintrpret that 1600 steps/rev on the driver setting
[21:08:45] <LeelooMinai> But what else could it be...
[21:09:04] <LeelooMinai> Well, hmm...
[21:09:11] <LeelooMinai> It's strange it starts from 400 though
[21:09:34] <renesis> maybe its a microstep drive in half step mode?
[21:09:37] <LeelooMinai> Where is 200:)
[21:10:04] <LeelooMinai> Maybe all off = 200
[21:10:19] <LeelooMinai> But still, that would mean that my calculations are correct
[21:11:40] <renesis> are you talking about the drive settings? i dunno what you mean by all-off
[21:12:27] <LeelooMinai> I mean it's not in the table, but maybe all off = no microstepping = 200 pulses per rev for normal stepper
[21:12:28] <pcw_home> is it possible the settings are only read at power-up?

[21:12:50] <LeelooMinai> pcw_home: There are dip switches on them
[21:12:54] <LeelooMinai> I mean on the drivers
[21:13:08] <renesis> they might only look at the switches during initialization
[21:13:30] <renesis> rebewt
[21:13:49] <LeelooMinai> Wait, what...
[21:14:27] <renesis> you may need to power cycle the drive for the new dip switch settings to take effect
[21:14:30] <LeelooMinai> The look at the switches, set what is needed and then what... How could they be changed thereafter? :)
[21:14:41] <LeelooMinai> No, they were set up like that for days.
[21:15:03] <renesis> you changed them or still the same?
[21:15:19] <renesis> also in some datasheet tables, 1 = dipswitch OFF
[21:15:22] <LeelooMinai> I did not play with them for days if not weeks
[21:15:37] <renesis> which is retarded even through it makes sense (pullup inputs)
[21:15:48] <LeelooMinai> The dip switch block has "ON" painted on it
[21:15:56] <renesis> customer doesnt give a fuck the the switches are lower side
[21:15:58] <LeelooMinai> I set it according to that painted on
[21:16:24] <renesis> *that the switches are low side
[21:16:54] <renesis> leeloominai: so it just changed recently? same linuxcnc config and dip settings?
[21:17:18] <LeelooMinai> No, linux conf I just edited - it's kind of first time run.
[21:17:25] <renesis> oh
[21:17:35] <renesis> you checked datasheet for the driver?
[21:17:46] <LeelooMinai> I just linked table from it
[21:18:14] <renesis> oh nice, missed that, i started line after
[21:18:23] <renesis> then went to far when reading up =\
[21:18:41] <LeelooMinai> O, crap
[21:18:58] * LeelooMinai beats herself with a "stupid" stick
[21:19:10] <renesis> it doesnt have a 200 pulse mode
[21:19:18] <LeelooMinai> My drivers are a bit different model:)
[21:19:30] <renesis> and i like that table
[21:19:32] <LeelooMinai> And apparently dip switches are different
[21:19:39] <renesis> ON/OFF instead of logic 1/0
[21:19:41] <LeelooMinai> Ok, solved
[21:19:47] <renesis> neat
[21:20:47] <pcw_home> if you are using a hardware stepgen you should set the ustep ratio as high as it will go
[21:21:17] <LeelooMinai> pcw_home: Will it not affect accuracy if the pulses are too fast?
[21:21:23] <renesis> i have a xylotex that doesnt really work =(
[21:22:06] <renesis> leeloominai: i think he means when the drive automatically microsteps to the next position
[21:22:13] <pcw_home> no, faster is better as long as the drive can take the step rate
[21:22:24] postaL_offline is now known as postaL
[21:22:42] <LeelooMinai> The driver has max 8000 pulses per rev so that's what 8000/200 = 80/2 = 40 sub-pulses
[21:23:06] <LeelooMinai> ok, I guess I will try that
[21:23:25] <LeelooMinai> Having fpga and all:)
[21:23:32] <pcw_home> so thats 160 KHz at 1200 RPM which should be OK
[21:23:34] <renesis> oh neat
[21:24:28] <pcw_home> above about 32 usteps/step its diminishing returns (not any smoother)
[21:24:52] -!- franco has quit [Remote host closed the connection]
[21:24:58] <LeelooMinai> I am not sure though how to set up all those timing parameters - so far they are all 5000, but I could not really find any specs for that for my drivers
[21:25:11] <LeelooMinai> Is this some kind of trial and error thing?
[21:25:33] <pcw_home> well the drive should have specs :-(
[21:25:50] <pcw_home> 5 and 5 will limit you to 100 KHz
[21:25:54] <renesis> timing diagrams are really hard!
[21:26:01] <LeelooMinai> Maybe I should search further then
[21:26:26] <LeelooMinai> pcw_home: So would you go with 32 microsteps or 40?
[21:27:08] <pcw_home> I doubt you will notice any difference but its worth playing around with
[21:27:39] <LeelooMinai> 32 is rounder, so I will go with that:)

[23:48:43] amnesic_away is now known as amnesic
[23:49:31] <LeelooMinai> Is this page still valid for new linuxcnc?
http://linuxcnc.org/docs/html/config/ini_homing.html
[23:50:25] <LeelooMinai> btw, it's inconsistent - uses LATCH_VEL then LATCHVEL - not sure what is valid
[23:50:40] <XXCoder> hm 69 bucks at harbour freight
[23:52:14] <XXCoder> lol passive agressive post. " on a side note see how my machine is not all surface rusted? that's because it's stored properly, be wary of any equipment with rust of any kind."
[23:52:23] <XXCoder> way to get sales dude
[23:53:15] <LeelooMinai> What, it's a good advertisment:)
[23:53:42] <zeeshan|2> LeelooMinai: becareful when youre homing
[23:53:47] <zeeshan|2> its so easy to break the switch
[23:53:50] <zeeshan|2> especially with the way you have iut mounted
[23:53:52] <zeeshan|2> *it
[23:54:02] <zeeshan|2> i broke mine!
[23:54:41] <jdh> mounted so they smash the switch instead of passing by it?
[23:54:42] <LeelooMinai> Hmm, you mean by putting wrong signs in there?
[23:54:48] <zeeshan|2> jdh yea
[23:54:52] <zeeshan|2> LeelooMinai: yes
[23:55:08] <zeeshan|2> its really easy to have it backwards
[23:55:17] <zeeshan|2> if you can
[23:55:22] <zeeshan|2> unmount your switch
[23:55:32] <zeeshan|2> actually dont even unmount it
[23:55:34] <zeeshan|2> trigger it by hand.
[23:55:42] <zeeshan|2> and see if it moves in the correct dorection
[23:55:45] <zeeshan|2> (the axis)
[23:55:57] <LeelooMinai> RIght, good idea
[23:56:16] <jdh> and mount it so you don't smash it.
[23:56:40] <zeeshan|2> jdh too late
[23:56:41] <zeeshan|2> :-)
[23:56:55] <LeelooMinai> I just mapped my machine to have 334mm X x 286mm Y and 146mm Z btw
[23:56:55] <zeeshan|2> if i change em
[23:56:59] <zeeshan|2> ill prolly throw prox switches
[23:57:29] <zeeshan|2> btw the command is "HOME_LATCH_VEL"
[23:58:16] <LeelooMinai> The page has LATCH_VEL
[23:58:21] <zeeshan|2> yea
[23:58:22] <zeeshan|2> but look down
[23:58:24] <zeeshan|2> the real command is there
[23:58:59] <LeelooMinai> So it's triple confusing - different names on the drawing, different in the table, and different in the text:)
[23:59:17] <jdh> fix it
[23:59:35] <LeelooMinai> I did not make it:)
