Which version of LinuxCNC are you running? I would expect the spindle pins to look more like "spindle.0.speed-out" on any recent LinuxCNC version.

To get a list of HAL pins that you can copy and paste from, in the HAL file insert the linejust after the block of "loadrt" commands
Then start LinuxCNC from the command lineLinuxCNC probably won't start, but you will see a list of all the pins, and also a message about the first problem it has found in the HAL file.
Copy the pin list from the terminal window and squirrel it away in a text file for reference.
(Copy and paste in the terminal window is generally ctrl-shift-C and ctrl-shift-V as "normal" Ctrl-C is "Cancel")

I took the PID solution and modified the code a little. I initialized spindle-index-enable to 1 when starting Lcnc.
I also used ABS on spindle-Pos-fb-abs.
The spindle is positioned, but only in certain cases:
- When starting Lcnc, if I've never rotated the spindle at speed and the angular displacement is small (less than 20 degrees).
- If I rotate the spindle first and then try to orient it, almost every time, it will start at maximum speed, without orientation.
- If I rotate the spindle first, and then reposition it slightly by hand with my index finger, I can orient it, but always with small successive angular displacements.

It's progressing little by little, but from my point of view, it's more tinkering than mastery...

 

ec_generic should autoload when ethercat master service is started and "generic" is mentioned in /etc/ethercat.conf
There was an issue where it didn't and the user had to modprobe it manually after start of linux.
Suspected Secure boot but it was off like in your case. Never understood why it didn't load.
I guess you have to experiment to see if you can get it to autoload.

 /usr/sbin/ethercatctl is the file that loads the modules when the service is started, it's a bash script.
 

OK, found it! It because of G64... Case closed

Only the parport gets disabled or LinuxCNC also show an error? (Not sure if the parport gets disabled after a following error?)

Perhaps a parport driver is interfering, what does lsmod show?

Is in the BIOS the parallel port set at ECP/EPP/AUTO? Try EPP or ECP

Too aggressive timing for the steppers?

Power Management in BIOS?

Sorry, i thought i filed it in the "German" section. Could someone please move it there?

I've been having a hard time trying to figure out how to get my router's Yaskawa 616g5 vfd connected up and running with my 5i25 - 7i77 setup.
I can't seem to find a good example of the HAL code and I'm not across HAL enough to figure it out for myself. 
Just trying to get the absolute basics working. Spindle on is already connected and working. I just need to figure out the 0-10v output from analogue5.
The VFD can be configured for 0-10v or +-10v. I'll be setting it to 0-10v, no need for it to reverse direction.
I've seen versions with scaling and versions without, versions that set the scaling directly in HAL and others that set the scaling parameters in INI.
As I understand it I shouldn't need any scaling, just SCALE, MAX and MIN values of 24000 and 0 (or maybe 6000, the slowest the spindle is rated for) 

I think I had it close to working at one point but the scaling must have been off. I've not gone as far as connecting the vfd to the 7i77 yet, just probing the output pins on the 7i77 with a multimeter. I was reading 0.4v when the spindle was on and 0 when off but in trying to figure out why the scaling was off on that particular iteration of the HAL file I deleted something and couldn't get LCNC to run. That was about the 15th attempt so I gave up for the day.

Most of the code I've tried to work from has looked like this or some version of it.
If someone has a similar setup and could share their HAL file or give me some direction on the bare bones that are required to get 0-10v working I'd really appreciate it.

ec_generic was not loaded.
After modprobe it I can see slaves
How to autoload it?

 Hi, mal wieder eine Anfänger-Frage... Ich bin mit meiner gerade erst fertig gebauten Fräse bei den ersten Tests und habe mir mal einen Stift eingespannt, um erste Schritte zu machen. Als Übungsobjekt habe ich den LinuxCNC-Schriftzug aus "Axis" genommen und ein paar mal mit unterschiedlichem Vorschub geplottet - F400, F1200, F2400, F3600 und nochmal an der gleichen Position F900.



Beim untersten Schriftzug sieht man, dass unterschiedliche Kurven enstehen (aussen F3600, innen F900). Jetzt frage ich mich natürlich, ob das Schrittfehler sind, oder woher das sonst kommt und was man dagegen tun muss?

Danke im Vorraus
Chris
 

Still struggeling a bit with the homing sequence.
In addition to the home switches I would like to use the encoder index to home. But the index is not found while homing.
So if I write "HOME_USE_INDEX = YES" in the INI, then the homing sequence does not end, even after 4 or 5 motor revolutions the index is not found. The index signal itsself is present- can see it in the oszy, it is also wired to the 7i80, so I assume it is not linked in the HAL correctly.

I hope someone can help me with this issue.

Thanks
Sigi.

 
 

Getting the control box together some is being reused from the original system such as the transformer the motor starters. 

The phrase "again" wasn't referring to a previously asked question, it's just a "turn of phrase".

Like the other members responding here, I am a bit confused as to "MEM" in the context of Linuxcnc, as far as I was aware gcode isn't "stored in memory for reuse" but reread from a loaded file.

Now whilst you appear to frustrated it is no use getting upset when you are not getting the answer you require.

Now if you can give some details regarding your OS, version of Linuxcnc and any configuration files, that would be great. Even better would be a short video of what is happening.

One must remember that this is a multinational forum and whilst some are fluent in English it is not their native tongue.

Are you sure you are running LinuxCNC?, I've never heard of MEM mode.

Thanks Chris.

Despite reading almost every post on this forum, i have no idea what that means.

Again, does the machine move at G0 speeds or just the gcode preview on LinuxCNC screen?

 

MEM refers to Memory Mode. This is where you select a program from the machine's internal memory and press CYCLE START button to run it automatically. 

Again? You never asked a question before this, so how is this "AGAIN"?
Ponder this: If "just the gocde preview on the LinuxCNC screen" is the only thing moving, how could it crash if I had a part in there....
Look, if you are not going to read what I posted where I clearly described what happened, there's little reason to continue this conversation.
