You have encoder feedback ?

So I took some time and created a generic driver for EL2502 that works for me. I can control frequency and duty cycle with two seperate 16bit integers. This has been tested only in one channel but for second channel, PDOs should be 1603 with the same sub indexes as for the first. 
SDO index 02 is to set control number from SINT16 to UINT16 and index 07 to change operation mode to frequency AND duty cycle.
I hope this helps you.

I found my self in a situation where i could end up getting sucked into the lathe department at work and had an idea to build some kind of test simulation for testing macro programs and testing of programs in general. So i thought it would be neat if i could create some kind of virtual machine for this. i have never tried anything like this in the past so who knows how far i can push the limits with what is able to be done with the tools we have here to work with? Being a mill guy for the most part and looking at lathes with a main and sub spindle with XYZ with a 4th linear axis on the sub spindle for part transfers and phase snyc on both spindles with some of these lathes having a second turret on top of this kinds makes you take a step or two back to get your ducks in a row when your in a situation where there is no one to ask questions because the last guy that knew these machines ends up retiring. So that's basically how this project came to light

what i have managed to do so far is get all 3 of these programs to play nice together open up and render my model and create a 3D orbital view with a zoom feature with a custom viewer so far. i almost gave up on this project quite a few times but got things working this past weekend. i am not just getting into the custom UI with designer which i am just now starting to understand a little bit.
added a screen shot of the model to give you and idea of what is being worked on this is by no means final or even close to being done. i had no idea what i was getting myself into when i started this and thought it would not be to much trouble until i started and that went out the window pretty quickly once i dove into it  

 

The boards looks nice, is it a hobby or are you going to sell them?

I guess you already know this but just in case, here is how you create individual pins for i/o

in many cases autotune broke parameterisation, for example Siemens s120 with their servos working like a charm, but if You use third party supplier of servos, just be sure You are using parameters delivered by Your supplier of servo, if supplier have not parameters for Your driver, don't take it, auto tune mostly broke settings, same manufacturer of drive and servo have to work, but i think it can be price reason (in comparison to Panasonic MINAS A6B for example)

It wont work,(the simple explanation since you don't understand\haven't read the links) the RPi SOC doesn't do the memory\port mapping the parallel ports require.

When searching about this a thread I started came up, regarding SPI, mentioned parallel ports don't work with the RPi.

Rather than banging your head against a wall look at the Linuxcnc RIO project. Or get a Mesa 7i90HD, it's really quite cheap if you are based in the USA.

I think I have wrapped my head around my stepper motor and limit switch wiring. Regarding the spindle, I have a few questions:

The inverter is a woods eTrac x2c and the manual offers a nearly overwhelming number of options. I was never able to see the spindle working with the stock
AMC controller. I have attached the relevant table from the inverter manual and it seems like I should be able to use the analog spindle interface to provide 0-5vdc signal for speed control (vin). Do I simply use inputs on the 7i96 to conteol fwd/rev and a ground connected to the inverter common? Is that all there is to it?

The original wiring from the AMC controller to the inverter is somewhat different and it isn’t obvious that the AMC was actually able to control the spindle speed. It is connected to use 4 preset spindle speeds and the AMC has wires indicating an acceleration/deceleration signal, as well as some connections to NO and RCM.

 

 

Thanks. I tried all three variants on both parport cards. Did not work.
Let's not spend any more time on this. appreciate everyone's time and effort.
I'll likely jump back in this fall when I have more time.

I deleted my previous post as i missed a crucial point, sorry for the confusion.

Possibly. I have not tried it but it will be up to the devs to increment the Python version. I thought that would have been done as linuxcnc 2.9.4 is in Debian 13 natively.

M3 S10000 ; works, spindle starts and spins up
M5 ; works, spindle stops
G53 G1 F4000 Z-10 ; Spindle does not move and GCode interpreter seems to be hung!

Is spindle-at-speed true? if not, pretty sure this will hang waiting for spindle-at-speed to be true.

One advantage, If you have step/dir servos, returning the position information to LinuxCNC
allows LinuxCNC to monitor the actual following error during operation.

DELETED as i missed a crucial point so my reply was not correct.
See PCW's reply below

OK, so an update on this issue.
Tonight I had some time to isolate where the problem is happening, and I can bring it down to just a couple of commands.

I start up Linux CNC, toggle the CNC on and home it, this is my start point.

Now in the MDI window I type the following

G53 G1 F4000 Z-10 ; This works, carriage moves down 
G53 G1 F4000 Z0 ; This works, carriage moves up 

I can repeat the above multiple times, the carriage moves up and down as expected.

BUT, if I type the following (either after typing the above or after a clean start)

M3 S10000 ; works, spindle starts and spins up
M5 ; works, spindle stops
G53 G1 F4000 Z-10 ; Spindle does not move and GCode interpreter seems to be hung!

On the console I see the following output 

mdi_execute_hook: MDI command 'M5' done (remaining: 0)

I've attached the full console output from the linuxcnc command 
 
 

Oh good, and oh .... i don't know....
