I have a problem with "A" axis.
I connected my rotary axis "A" for the first time.
In general configuration I have "A" axis as angular.
I enabled the "A" axis  and set the steps per as my other axis for now.
But when I energize the servo motors instead humming sound and steady position on all axis (X Y Z) my "X" axis went on and run the table to the limit but the "A" axis didn't move.
When I disconnected the 12 pin plug from the rotary axis "A" and re-energize the servo motors, both X and A axis went on and they were running wild.
I don't understand why X is responding that way.
In pin ste-up  have  X 2-3, Y 4-5, Z 6-7 and A at 8-9 

When no "A" axis is connected everything works fine , no problems. 

Any suggestions ?

Dont see anything wrong in the xml at first look, what happens if you swap the pin assignments for A and put them in X values?

Hey Hood, I see that A is not enabled, and the macro pump is running. Also, there are duplicate pin assignments for B and c axis although they are not enabled. Not sure if that's a prob or not but seem to remember it's best not to do.

BTW ... Congrats ! ! ! Over 13,000 posts and your batting average is still improving.
Cheers !

Yes I just presumed he had disabled the A due to the problems and had maybe been messing with the other axis. Its always best to get a xml in the state that is giving the issues so might be a good idea to set up again so the problem is there then shut down and attach that xml.

The average may be improving but the eyesights going with staring at the bloody screen so much Grin
