You need to buy the little crimp terminals separately, and you need a pretty small crimping too.
that's just the socket?

are you talking about field power on the 7i76?

all my lathe subroutines http://gnipsel.com/shop/hardinge/hardinge.xhtml
so you add a few lines to your ini file and copy all my subroutines
my [DISPLAY] section of the ini file http://pastebin.com/pt6Jx9nZ
anything with a # is a comment
oh and this line too
TOOL_EDITOR = tooledit x orien back front z diam
My lathe subs are prettier than ngcgui, but can't be assembled into a G-code file (in fact, no G-code is produced).
yours does look better. how does that work with no G code?
It uses fixed G-code subs, and calls them with parameters, rather than creating a g-code file that can be re-used.
ok, that makes sense
wheres ur subs andy?
Dewey like to use helper subs with ngcgui
I get confused by them
(Though I am working on some mill tabs that simply MDI the G-code in from Python :-)
I do like the way ngcgui can concatenate the subroutines into one file
Yeah, there are definite advantages to ngcgui if you make things more than once, and know what you want to make.
true, that would work for single ops, but im my case with multiple tools and such, im not sure it would work nicely...expecially without seeing the toolpath
My subs are more like a 2-axis version of manual lathe power feed :-)
even for one offs it is faster than anything else I've tried
Yeah, my stuff is for standing at the machine and thinking in metal :-)
That's why I have decided I don't need a "proper" CNC lathe, the sorts of things I do suit the conventional centre-lathe layout and access for measuring tools etc.
say for example I chuck up a blank and touch off Z then I can take a facing cut and zero Z, turn the OD, drill, rigid tap, part off etc just by filling in the blanks and telling ngcgui to use all of them in the order I placed them

hey jt im trying to install the features at the link first and see how they are, https://github.com/cnc-club/linuxcnc-features
but i cant install python for some reason
can u guide me through it?
it's greek to me
is says type in terminal sudo apt-get install python-1xm1
says couldnt find package
Wheres my typical process would be to open the facing tab, load my T1, jog close to the work, touch of Z to 1, then face to zero. Then realise I haven't quite cleaned up enough, so face to -1mm, then re-touch off. Then I might turn a diameter to Z = -20, offer up the mating part, decide to make it a bit longer, so do it a bit further. The way I work is very iterative and hands-on.
you should have python installed, just open a terminal and type in python
yup i got

Either other folk are lazy, or bad at google, or I am particularly good at thinking of ways to search. (viz the wire-end rounding tools I found for that guy on the users list).
so I tell it the diameter and how much to face off, if it don't clean up I run again

So, any Mesa card folks around? I got the Mesa 5I25 and the matching 7I76 daughterboard for my mill, all the stepper outputs work now, so now and I am trying to get the analog 10v spindle control to show signs of life on a digital voltmeter. Its wired up to 12v in the proper circuit, and my 5th stepgen is set for spindle, but what else do I need to do to make it work? I don't see changes on
the meter when I play with the + and - buttons. The numbers go up and down in the test screen, so stepgen is working, hmmm.
I had a very interesting problem, it took me a whilr to figure it out. The Y axis went very tight at the column-end. I initially thought that it was wear in the slides (which would make me sad), but it seemed odder than that, the table almost seemed to levitate at the column end. It was one of those things solved when not quite asleep. The swarf-shield had to be modified to suit the new nut:

Spindle speed isnt a stepgen
Mr_Mayhem: I don't suppose you are the Mayhem I know from Ixion?
No, I am different Mayhem, hehe.
Mr_Mayhem: If you list the HAL pins you should see three pins with "spindle" in the name (IIRC_
ok let me get the list up on the screen.
I can't recall the exact names, but id you have linuxnc "live" just open a terminal and do "halcmd show pin *5i25*" and you should be able to see them.
jthornton: The swarf shield hole wasn't quite big enough, so when the shield hit the column and started to slide, it pushed the table sideways. As the left-side guide is a V way, the effect was to push the table upwards......

CHNCguy: You still there? I am sorry, I got distracted.
I see spindir, spinena, and spinout.
Them be the ones. spinout is the spindle speed
I see the rope
There is probably a parameter for scale. halcmd show param *spind*
Sorry, don't type the "d" there.
I am being lazy, I have a 7i76 wired in behind me, all I need to do is boot that PC.
Yes, spindir - invert, spinena invert, spinout - maxlim, spinout - minlim, spinout - scalemax.

well, I don't know but it goes up to 24000 rpm. I know the vdf can scale it, but I haven't played yet to that level of detail. I am just trying to see my voltmeter go up and down at this point. I do have the 12v wired to the 7I76.
If I set 10v to be 24000 rpm that would be a good start.
[01:29:02] -!- rob_h has quit [Ping timeout: 264 seconds]
If 10V is 3000 rpm at the vfd then the HAL file needs to include "setp hm2_5i25.0.7i76.00.spinout-scalemax 3000" to set the scaling, then set the min and max similarly to what you want the limits to be.
Mr_Mayhem where in the pncconf did u set your spindle up at?
(check the parameter name, I am guessing). Pncconf might know how to do this, I am not sure.
It was done as a 5th stepgen set to spindle.
Yeah, stepgen, he be wrong.
[01:30:40] -!- tjb1_ [email@example.com] has joined #linuxcnc
ya i think thats wrong
there is a place
in smart serial 0
but my pncconf crashes when I set it to spindle output
not really crashes, but just doesnt let me finish, gives me errors
I tried the only other spindle thingie I could find, smart serial 0. It always crashes the pncconfig.
I doubt it actually "crashes"
I think this is the 3rd tab, smart serial 0, yes?
yes why does it have it there if all we get is errors, we must not be selecting something else also
Now, here is something that might surprise you. When folk write software they tend to choose error messages that mean something. They may not mean anything to you, but I bet that Chris would know exactly what the error message meant.
One would assume this, yes. Maybe we need a dependency.
Yeah, he would be the person most familiar.

The smart-serial stuff will only work if you have a smart-serial accessory attaached to TB3. The spindle VFD should actually be on TB4
(I just noticed that the 7i76 manual was open in the background all along...)
yes, tb4. I assumed it uses pcm pulses or something. So what signal does control the output of the 10v output pot? hmm.
The 7I76 spindle stuff is part of sserial channel 0
I see the pinout in the manual but nothing about how to select and set it up ;|
ok. That't the one tab I get the error on when I set it to spindle.
do you have field power applied?
at the end when I click apply.

Both yellow LED are lit steppers work fine.
probably a pncconf bug then
if this is the latest pncconf you will have to edit the hal file by hand
I have the last cd image, but it seems the same as the one I dl in March 2013
I am playing with pncconf here, having also found a live LinuxCNC VM also lurking in a background window
Funny what you can find just laying around on your system.
When you get to the "Mesa0 Configuration" stage of Pncconf, select the firmware you actually have (probably 7i76x2)
Then click the "accept component changes" butan
(oops, using the wrong vernacular there, that's the gaming window where they use "butan" :-)
I think it said 7I76 x1 in the help page that showed pinouts.
under the help/ Output tab in Pnconfig
Fine, choose that, then hut the big "Accept..." button
Then Smart Serial 0 tab should have a 7i76-Analog Output sub-tab?
Done, it did it's progress bar animations, and is done.
Then set the analog output to "Spindle Output" and it ought to just work?
No, it has 7I76 Mode 0 I/O Card Tab 0, Tab 1, Tab 2
They are all 7I76 Mode 0 i/O Card x
Can you put a screen grab on imagebin?
Andy is likely running master
Yeah, that analog tab is not there.
I can't do the pastebin right now as the box isn't wired, what do I use to take a screen shot anyway? I am a linux newbie.
I'd have to copy the image file over via usb dongle.
u said u have tab 2 right?

[01:52:23] -!- terabyte- [firstname.lastname@example.org] has joined #linuxcnc

it should then say 7i76 mode i/o card tab 2
its the 3rd tab
top drop down select spindle output
And, in fact, Help-about claims to be "beta 1 version"
Unused analog input is noticable.
then select spindle output
When I select this, I get the error when I get to "Apply" at the end.
same here.... :( BOOOoooooOoooOoO
hey guys how can we edit the file manually?
Yeah, that's how I feel.
there has to be another setting that we are missing which causes the error, I don't have field power on right now so that might be my prob
I always edit the files manually, FWIA
Andy mentioned an 7i76-Analog Output sub-tab, which is not here on my setup.
I have what you said, IO Tab 2
catching up here... those terminals are C-Grid
to fit the 7i73
ahhh i see
I have to eject, I have a dinner to get to. Sorry about that. If you know what to do manually, please put it here and I will try when I return from dinner.
haha i know now........
i have ur answer ;D
ill type it in here
have fun :D
thanks, I really appreciate the help, all of ya.
********** OK so this might work ************* on the 3rd i/o table (I/O Connector 3) on the right hand side num 0 says unused encoder, you should select spindle input here. Then change the smart serial 0 tab 2 to spindle output. Then you will be able to test the spindle, if it runs here then ur good. I don't have field power so I can't test, gonna
try it tomorrow. Hope this gets it working ;)
andy, how do u modify the file to work the spindle?
which file and what do you do to it?
[02:01:16] -!- uw [uw!~uw@unaffiliated/uw] has joined #linuxcnc
Manually it is just a case of adding "net somesignalnameorother motion.spindle-speed-out => hm2_5i25.0.7i76.0.spinout" to the HAL file.
You can choose any signal names you want, and anywhere you use them in the HAL file they will represent the same value. The pins created my the motion module (which include the spindle speed) are all listed here: http://www.linuxcnc.org/docs/html/man/man9/motion.9.html
any reserved words on those?
There are no reserved signal names. In fact I think that signal names can be identical to pin names, even, but that would be asking for trouble. :-)
for any number of reasons
Ah, no, HAL does refuse to allow you to do that "Signal name 'motion.tooloffset.z' must not be the same as a pin"
andypugh, when you did your LCD were you playing with the 7i73 at the time?
i ran across your lcd pic the other day again..
Yes, the LCD is connected via a 7i73
do you remember how the lcd shows up in hal?
or is it just io pins
it is just a single pin.
what interface was the lcd?
so the 7i73 handles it?
Yes, one byte per servo thread, (gives a perfectly adequate update rate)
lcds are pretty slow anyway
The "lcd" HAL component handles the formatting, and creates net-able HAL pins
i haven't looked into it much yet
woohoo, just got the first signs of motion out of the VFD driver i've been writing
(modbus-rtu control of an Emerson/Control Techniques Commander SK)
"lcd" looked easy when i started it, then I foind that there was no floating-point printf in the kernel, so I ended up writing printf from scratch on HAL...
Right, I am going to retire now, in the hope of seeing actual AM tomorrow, and getting stuff done.

I'm back CHNCguy, Andy, in case you are still around tonight. I have a new screen for the spindle settings after following those pncconf instructions. Looks good so far.
Bottom line, you have to set the encoder input to prevent the error. I wonder, what if I have no encoder? Because I don't. Best I could do would be some kind of voltage coming from the vfd which corresponds to frequency/rpm. Hmmm. I will play around with this new arrangement to see what happens.

The hint I use is look at the 3d screen different views to determine which part of it is out of bounds (the red rectangle is the bounds as set by earlier settings) Then touch off more in the opposite direction.
vikingsraven, u probly neeed to set a machine postion, G28.1 normaly its a home point
then set a work postion also probly, ie G54, not sure what demo program runs code wise you might need tools if it uses any
ok thanks guys, the touch off is the sort of referencing button. sorry first time trying this software, linux and this setup. Huge learning curve. Did try the manuals but im dyslexic and it all mixes up!
Ha, well good luck to you. It is a fairly steep learning curve but its so nice when you get it all to work! Nice to see your own parts get cut when you are set up.

Basically you have a zero point in your drawing and final gcode file. You put the tool tip to the same place on the stock (usually the corner closest to home position) and this sets the machine to use the same zero position as your gcode file/drawing.
so both "zero" reference postions then become the same.
You make linuxcnc follow the convention used in the gcode.
so first you set home for each axis (near the lower limit of travel for each axis), then you touch off x and y on the corner that is considered zero in the gcode or drawing. Then touch z barely to the top of the workpiece somewhere, assuming it is flat.
The home positions become "soft limits" which prevent the machine from moving too far in the minus direction.
The upper limits are set in the stepgen settings, generally.
And are keyed from the home positions as a reference.
[11:23:21] -!- reksio1 [firstname.lastname@example.org] has joined #linuxcnc
So, the general idea is, home all axis near their lowest minus position, then touch off x and y to the zero point of the workpiece on the table. Then touch off z to the top of the workpiece. It can get much more sophisticated, but that is the basics.
The idea is, the whole planned motions in the gcode file must fit within the box you defined and touched off, without hitting the lower limit (home) or the upper limit. Or drilling into your table, hehe.
That for each axis I mean.

thanks, found it on their page
are you up to speed on hm2 stuff? i'm having some weird issues with 2.6.0~pre and trying to sort it out
(current git as of yesterday)
sure what's up?
i've been happily running a 7i43 on 2.5.1 for about a year, using CONFIG="firmware=hm2/7i43/SVST4_4B.BIT num_encoders=2 num_pwmgens=2 num_stepgens=4"
due to some other development i'm doing (modbus driver for a vfd) i pulled latest git yesterday and tried to get my basic config up and running on that.. the issue is that the stepgens seem to be taking up a bunch of extra pins which i am using as gpio in my setup
the formerly available pins now show up as "Table2Pin" "Table3Pin" etc... I found reference to them in pins.c in the hm2 driver, with a comment " FIXME: these depend on the stepgen mode"
one sec and i'll paste some text somewhere to show you
ok, pastebin output from dmesg after start
Thats because Andy added table mode to the stepgen in master
its arguable that the pins beyond step and dir should be left as GPIO unless the config line invokes them
[15:02:12] -!- dgarr [firstname.lastname@example.org] has joined #linuxcnc
working one: http://pastebin.com/sK3BHW4a
not working: http://pastebin.com/UjqAznHy
pcw_home: is there a config argument to turn that on and off? i don't care so much what the default state is, i just need to turn those back to GPIO and get my stepgen's back to 2 pins only
i did look through the code a bit yesterday and couldn't find anything obvious, but i only tried for 15 minutes or so
Not until the source is fixed
ahh, Andy left debug code
this is classic yak shaving, my main goal was to get my vfd driver written... which i've done, so now i'd like to get it running with my real config and not the sim
i'd like to contribute my vfd driver back once i polish it up a bit
a fixed bitfile is a workaround
i'm totally fine with a workaround for now, any pointers?
jthornton in your ini, all lines like: NGCGUI_SUBFILE = /home/john/linuxcnc/subroutines/face.ngc
would be simpler and more portable written as NGCGUI_SUBFILE = face.ngc
because linuxcnc always has to find the file in the search patch: PROGRAM_PREFIX, then SUBROUTINE_PATH
and SUBROUTINE_PATH already defines /home/john/linuxcnc/subroutines
If you are setup for building bitfiles is easy, if not its a 5G download of the tools
the full Xilinx FPGA suite?
dgarr, I'm not sure why I did that
CHNCguy, pastebin the exact error
well, i'm not opposed to it... i'm a bit rusty on VHDL but it's probably not even that involved
[15:11:13] -!- vikingsraven has quit [Quit: Page closed]
are the bitfiles part of the hm2 firmware? i ask because i'm still using the same firmware files from my 2.5.1 install
its editing one file: PIN_SVST4_4_48.vhd
well i was actually looking for an excuse to play with the FPGA code anyway, so this is a way to force the issue
is this reasonably accurate? http://tom-itx.dyndns.org:81/~webpage/emc/xilinx/xilinx_install_index.php
presumably that's your site, Tom_itx?

i was working at one of the first internet providers in my area by the time 28.8 was common... we had hand-built racks of hundreds of 28.8 modems, stripped of their plastic cases
[15:33:52] -!- gonzo__ [email@example.com] has joined #linuxcnc
what an ungodly mess that was, but it was better than having hundreds of wall warts and all those plastic cases too
I got an ex isp rack, that had cased modems but a common industrial psu and flying leads
the common psu makes a huge difference
our solution was about as slick as it could be... the guy in charge of that was an old retired engineer.. he fabricated some really nice cases out of clear polycarbonate, so each modem slotted in nicely
but you still had a rats nest of serial and phone wiring coming out the back
Speaking of wall warts I notice On-Semi has a chip whose entire purpose is to discharge the AC line filer capacitor when the wart is unplugged

anyhow, my probe works, can see the pin in halmeter
during pnfconf i selected the z probe ladder
and in the HALUI section the MDI commands are there
I need to figure out how to invoke this
is the input pin wired to motion.probe.input ?
i was able to take the patch from that commit and do patch -p1 --reverse to back it out
for some reason the man page reverse patch failed, but who cares
the pin mapping in dmesg looks correct, now it's on to ripping out the stuff to run my old spindle and get the new stuff in there
it is wired to the probe-in pin
i can bring up the halmeter and select probe-in
and watch it go false to true as it should
ok so a probe operation is invoked with G38.x
[16:32:01] <pcw_home> http://linuxcnc.org/docs/html/gcode/gcode.html#sec:G38-probe

tangentaudio: does all work
yes, i backed out a change that andy pugh made a couple weeks ago and that fixed it
good to know
he had some development code in there for table-driven stepgen, and it breaks normal 2 pin step/dir operation it seems

I'm sure it does if you have the lathe package and I assume you need a lathe package
why would you want to use mastercam for a lathe?
could be worse, you could be using mach and losing steps in Z and cutting into the table when you you thought you had 0.020" clearance

so I am thinking about springing for a VFD for my tiny desktop mill, but I will size it for the real sized bridgeport or equivalent I expect to buy in the next 1-3 years
can I expect good control running say a 1/2 hp motor with a 3hp VFD?
3hp sounds like enough for me, this is a hobby shop that I hope to turn into a tiny jobshop kinda deal on the side, but deff not a production/pro shop
I just can't find any info that says if it is good idea to run a tiny motor with a large VFD
single phase 120v input right?
probably on a 50 amp breaker
I have used ac lenze vfds with great success
no use rating a vfd higher then ur application unless u plan on upgrading the motor
well I do plan on upgradeing the whole machine
U can get a 1hp vfd for cheap, 3hp starting to get expensive
so I don't want to have to replace my VFD when I upgrade
I was looking at GS2 series stuff, and the price does jump, but its not like a 1/2 hp model iss free, so I figure spend once
well u can get away with a 7.5hp ac lenze vfd for about 500$, it takes 240 single in and outputs single and 3 phase out if you want, when u upgrade, its gonna be 3phase most likely
actually it looks like 3hp is as big as 240 single phase gests
at least on what I can find, do you have am odel name for what you are talking about? I'm on the lenze website now

Are you sure that you will want to disable the mini-mill when you have the Bridgeport? I would say that you might as well get the right-sized VFD for the Mini, then the right one for the BP.
probably can't afford to keep both, since I am waiting to buy the mill till after I buy a house lol
I'll be able to put the original motor back onto the mini mill and resell it pretty easy I would hope, but you have a decent point
best case scenario: I lose both my
real jobs and am forced to take up "building junk for other people" as a full time job and can justify all the toys on my wishlist
[21:29:14] -!- thomaslindstr_m has quit [Remote host closed the connection]
sorry back now ;)
true I agree with andy
but with the shear cost of converting a manual mill to CNC, I am not too optomistic
well I can always buy a small VFD when I get the bridgeport, now that I think of it!
so I'm not painting myself into a corner lol
[21:30:47] -!- thomaslindstr_m has quit [Client Quit]
well here is something I have learned from converting lots of machine (my first one is linuxcnc I am doing now, but in the past with mach 3) make a machine, make parts, make money, then grow
I have built 2 companies from the ground up, if you want to get bigger and afford more toys, start producing now, then a 500$ vfd would be nothing in the retrospect that you just made 4k for maching 2 parts with ur bridgeport

I used the HF version, which worked good enough, but the roller was a very sad endevour
do you need to use it once a month or once a week?
I'd like to just make my own control cabinets vs what we pay for off the shelf
heh, gather dust for 6 months , then 100 cabinets
you may want to stick to CL or ebay for a real unit
the Jet units just don't look like they would hold up for long
or the others at NorthernTool
but if your time isn't super valuable, it will work, I just think your time could be better spent, and the corners aren't super crisp, but I didn't use it too much
it won't just fall apart in your hands tho, you just gotta tweak it a bit and learn to massage it right, if its like the HF model

trying to find a nice TIG for aluminum sheet up to 8ga
can't decide between Syncrowave or Dynasty
I've heard ppl who love thier syncrowaves, but thats as far as my input goes there
I own a TIG that is 25 years older than me, so not much help there
they are very popular
lots of older HF units on ebay
I would check out weldweb or weldingweb for better info
I would NEVER use a HF welder
and I am a cheap bastard
heh... high freq
half my shop is HF, but still I have had horrible experience with even older craftsman welders and will no longer buy anything but the big three

but still not gonna waste my money on a HF
^^ MIller HF
not the Harbor :)
had me scared for a while there
I recently failed to talk a friend out of buying a HF mig welder
I am not gonna be answering his calls when he wants help later...
in China the mindset is that you want a welder you can carry on a scooter and lasts for 1 year
I 'learned' on one of those machines, the guy teaching me told me it was decent
20% duty cycle
so there are lots of units under $300 US
I still have no idea really how to TIG, stainleiss is a PITA, but I'll get it eventually
yeah, I have an old Solar MIG like that, good for sheet metal
all I have learned is I am glad I did not sell the water cooled setup that came w/ the rig
low duty cycle
yeah, lots of the older water cooled units around
esp in my unheated shop, when its below 40 degs, its nice to have a welding CABLE not a welding ROD on the back of the torch head lol
the syncros tend to sell for near the price of new around here

the fact it has selenium diodes instead of vacuum tubes is a selling point tho

and install the package with the dpkg line that is it

Quick dumb question: I think I updated using a deb file, but how do I tell what version of linuxcnc I have? The Gdebi updater says I have 2.5.3, but Axis says 2.5.0.
Synaptic Package Manager says 184.108.40.206, so I guess 2.5.0. Hmmm.
I ran $ sudo dpkg -i filename.deb, replaced filename.deb with the deb I downloaded for linuxcnc 2.5.3
