My cnc "dealer" did import them directly to austria/Europe
I am working on an VFD Toolchanger configuration fpr 3 or 4 axis Milling machines
And we will then order batches
so i can ask him when he is ordering the next batch if you need / want to

No i am fighting with spindle orientation

The o/p removed the link, and the pc has been removed from their web site. The only place I could find it was robotshop or something like that. After all that work, is there going to be a sustainable source?
RoBoard who make it, are a robotics company.
I found it for sale on a UK site and a US site, both of which show stock available, so presume availability for the time being.

Quite honestly the disk image was more to save me time than anything.
Much easier to provide a package that just works, than try to talk an endless stream of people of varying degrees of Linux knowledge, through a complicated build process.

(Update of status i have one cf with a manual compiled ok kernel and run linuxcnc 2.5.2 fine i had a parport config where i can also conrtol the vfd because of spindel orientation i have bought 8gb cf cards and used your binary package to be compatible ,..
that worked fine as well now i want to use GPIO
i did load down the code and compiled it in it should work
so now my confusion
1) the picture shows 2 times 8 pins
2) your text on tab 3 says you have the gpio as 3 times 8 pins
i tried the example nice but where is the pin ? i understand the masking but not where is which pin ?
so my question
would it be possible to use the "LPT" board "normal" like an lpt board
and on top configure the gpio board as 3 times 8 pins or like the picture says 2 times 8 pins
if i know which pin i can go to the machine and see if spindle orientation "likes" me

You will be glad to know it is quite simple, you have been looking at a picture labelled NCBOX-PWM
The picture for the GPIO ports never uploaded for some reason, I think the picture size limit was lower then
So here it is
The ports can be set in BIOS but I seem to remember thay are all IN pins by default

that worked fine
Thanks for trying it and reporting back, I know it works for me, but needed someone else to confirm

Verry nice thx for the picture ,..
i made yesterday pin 7 to respond
so i was afraid to use try & error for that pins now i am verry happy ,..
Question should i try something for the "audience"
my next steps will be
1) Spindle orientation ( i have an Voltage divider on an 24V conactless switch which i put in one of the pins
2.) Toolchanger carousel
2.1) 2 Relais (24V) for left right and turn on
2.2) 2 24V conactless switches for index and posistion of the turret
2.3) 2 endswitches for Carousel is back or is in front
2.4) 1 Solenoid valve (which will be an 24V Relais

3.) 2 Relais for the spindle operation
4.) 2 Switches to check spindle position
the rest of the pins i will use for Buttons
![;) ;)](/media/kunena/emoticons/wink.png)
so on fr i will work on Spindle orientation
meanwhile i read a lot to see if i use classicladder or write an component for toolchanger
thomas
Which means if anyone want to use that small NCBOX i can try some stuff if needed
in the end of the project
one of the box will go on my turning lathe -> yes i want thread with it
![;) ;)](/media/kunena/emoticons/wink.png)
and the 2nd box will go to the mill with ATC

I do have your Board now um and running
I managed to use LPT for the normal Stepper configuration VFD and so on,..
I also managed tu use 2 Times 8 Pins of the gpio´s but now i am got stuck
I prepared an Electronic (which is where i am not 100% firm i am mecanic and software developer ,... )
where i use an Inducttive NPN Switch It is an IF71002 ( www.produktinfo.conrad.com/datenblaetter...NKG_I_US_100_DPS.pdf )
It works with 24V like i use the Power for your Board
then i build an Voltage divieder to get the voltage down below 5 V (between 3 and 4.5)
So then i found out that your pin "wants" minus pole to get activated ,..
I tried to reverse that with an BC547 Tranistor but i spend the whole day to day it doesnt work.
So i would love to use my Voltage divider .
Question 1 )
Is there a chance somewhere in the bios for instace (which i searched) to tell the board please use + as logical 1 not minus ?
Then my electronic should work immediatlely
Question 2)
Do i have to buy an PNP Switch instead ?
Question 3)
You developed the board probably you have an recomendation how to tacle that problem
thx

Pending any reply from Anthony, have you thought of just using the 24v from the inductive proximity switch, to switch a 5v signal of the correct polarity, rather than directly connect.
Found this circuit too
www.cosel.co.jp/en/data/pdf/reverse_polarity.pdf
I'm sure Andy, Jon or PCW will have loads of other ways to do it.
