Maybe I am having a senior moment, but how do you test the step/dir with a 7c81 when you can’t get LinuxCNC to run?

hi
i am cambridgeshire , close to peterbrough . how far are you from there?
M1 is close just how north are you?

im sure folks can help on here etc alot of info etc on the forum now. what is the problem you are having? is there one part you are having issues with? is it linuxcnc side or wiring it up ?


what is the machine in question any photos you can share etc, how much work is already done
what is the system, servos or steppers?
can you share some info here?

i have done many linuxcnc retros, all big iron mind you. laths & mills, and a few old denford mills & Lathes for people over the years... all with mesa cards , using old drives hard ware & new etc.

It is not possible to change a parameter in the hal file from the gui. Is it true?

As per the first post this is an ET60 so it has encoder inputs and associated firmware. The ECR60 is open loop only.
I wonder if you would be so kind as to share your working config?

Thanks, the axes move perfectly!

I've just set the PID parameters for my axes.
i'd like to know if bounces are ok or should i have as few as possible?
because the procedure is very well written, except that it doesn't specify what scale to stop at.
At 50 mv/div, are bounces negligible?

the images are relative to my X axis (with the turret), which is why there are more bounces when drawing. Im actualy at P=125 and F1=1

Slow speed UP (134 mm/min)
 
Slow speed DOWN (134 mm/min)
 
High speed UP (7127mm/min)
 
High speed DOWN (7127 mm/min)
 

I have exactly the same result

Edit: with 1.0 instead of 0.10 this is fine. Thanks a lot 

Since 'ci402.0.pos-scale' is a hal_parameter and not a hal_pin you cannot connect it to other hal_pins. You can only set them in using 'setp'.

As for 'ddt.0.out' that is an OUT hal_pin so it can only be connected to an IN hal_pin, so in your panel you can only connect it to something like a HAL_label to display the value.

Coincidentally that machine was also the very first machine I ever setup/retrofitted to run Linuxcnc (EMC2 at the time) and it has been running it the longest. But back then it started out as a simple 3 axis control with 3 step/dir commanded servos using software stepgens and no control of the VFDs. (The operator had to manually start/stop the spindles/VFDs.)

Then few years later I added a Mesa 5i25/7i85S combo, to add encoder feedback to close the position loop in Linuxcnc and fast hardware step-generation. Soon after that I used Mb2hal, to add control of the 8 spindle VFDs to Linuxcnc.

I have nearly a 20yr history with this machine since we bought it new, with more than half of those years running EMC2/Linuxcnc.

Once I get this done, my project will be completely finished. This is the last issue I'm stuck on.

One way to debug this is to widen the following error limits
and then plot the commanded and feedback joint positions
with halscope.

Hi...I copied a working axis as far as being able to jog with no error...but when I jog new axis (U)...I get Joint follow error...not sure what I am doing wrong...I tried to switch pins to another working axis and still had problem with U...other axis still worked after switch pin...??

I'm trying to do what the manual says, but I'm getting errors. I can't connect ddt to the testpanel, nor can I connect it to ci402.0.pos-scale. It seems difficult to do this for someone at my level.
 
 

Hi guys!I want to repeat the project Marco Reps, I bought these servo amplifiers but I have problems with starting. I have assembled a test configuration on the table and am trying to run it linuxcnc. I've made some progress, but I really need your help!I can rotate the motors if I connect to the USB in the leadshine Motion studioTell me, do I need to change any servo settings for the first launch?I get a response when I request ethercat slaveI have attached screenshots of my startup problem, all the Marco Reps files I am experimenting with and photos of the servo amplifiers (look at what they show on their displays? is this correct?)I really need your help in getting this system up and running. 

Bitte den ganzen config Ordner zippen und auch den Fehler posten.

Again, please clarify which drive you ended up taking. Because a closed-loop drive is sold by the seller at a slightly higher price. This is probably due to the low-level firmware. They might have sent you a cheaper version.
