Yes you can, not required though.
Just follow the steps on that post and make sure each step is OK before moving on to the next, by the time you enable the drives and the inherent danger with it, all the safety stuff is already in place and the most you get is a short thump when enabling the machine and the analog outputs re reversed in regards to encoder feedback, so if all is good when enabling the machine nothing happens, might just notice the DRO numbers changing a bit.
Oh, and please let me know if something is not clear or can be written differently for easier understanding.
Thank you.

got the 7i76 working, however i am getting a Field I/O fault from the 7i77. CR16 is shining red. i dont understand what this means. Pin W1 is in the default position. i have supplied 24v to pin 5 'vin'.

Thank you.

 

I apologize, I accidentally pressed the Submit button twice and I was no longer able to delete, I didn't find any options, I even tried to delete the content to try to delete the post.
I noticed a bug that if you quote a post and then edit the message your reply gets wrapped up in the quoted person's message
Anyway I'm still trying to figure out how to delete my posts I can't find an option when I edit, do I have to do it from the profile perhaps?

i just had a look at my old topics. You also helped me 2 years ago. i think the same problem happend. First i am gonna check if the field power is available

And you can not ignore feedback on analog servo systems if the motors are mounted on the machine, that ends up badly. But for testing on the table/desk you can, although there is no benefit to it, feedback must be sorted before even enabling the drives.
 


 

what I already did was putting low voltage to the x and y motors servo drive to see if I use the right inputs there and get movement. that worked fine. but it was with a lab voltage source, not any controller board.... 

that's kind of sad... can I buy a cheap servo drive to at least see if my config is right?
I mean, I get that tuning without the machine and the exact motors does not make any sense.
I just want to see, I did correct with Hal/ini pins to wire the machine if I get there....

yep! I try thanks

just did that, made no difference to how to hal conf looks like :?

Try setting all sserial to 000000 instead of 000xxx in the loadrt line, to many sserials enabled in the firmware so might be disabled with x.

do you mean this?

in case the hal and ini files are needed

Do they show in "show hal configuration" from the "machine" menu?

i also found the 7i77 servo tune post, wich I am currently reading to get used to what I need to do in future.

Is it this one?

No skipping steps there!!!

i already have that.
Or able to see that from the data?
