Thanks, I did not find that page! Gives me a better idea what they are doing. Seems to be step/dir centric control.

There is plenty of info there, and i do not think they use/work with LinuxCNC as the controllers use USB

A guy from Norway asked me about a CNC retrofit.  He wants to use planet CNC - I had never heard of it, but it LOOKS like it might be using parts of LinuxCNC, possibly.  Anyone know?  It seems to be multi-platform, but the web page is REALLY thin on details.
Thanks,

I did a quick test on my non-rt installation running 'cmake/nc_files/fillet/square_100x100_P5.ngc'.
1. it seems that inital deceleration and final acceleration along the fillet do not respect max_acceleration settings (50 for x in my case)
2. there seem to be acceleration spikes while traversing the fillet

Below is the captured accelerations for X and Y for the first corner of the rectangle:

 

I know they are 6-wire, but perhaps they are 8-wire internally.

They always are 8 wire inside, they all have 4 windings inside, they all have 50 magnetic de-tents inside, making it 200 steps per revolution. There are same types with 400 steps per revolution, meaning 0.9 degree per step instead of the usual 1.8 degree per step.
There are also 3 phase and 5 phase stepper motors, Vexta had some nice videos explaining all the types and versions on youtube.

Many thanks to both.  Good catch 16, 17 not 016, 017.  That eliminated that problem then it said pin 16 was already in use.  I ommitted the "spindle out pin 16 and 17" then it worked.  
4th Axis Mill opened up.
Can't find control for the A axis and some of the other directional keys have been switched around.  Where would I correct them.
Mandy, Many, Many thanks,

We've recently suffered a problem on our DMG CTX 310, with an error on the HSCI bus. Had to change the PLC I/O board, which is not cheap.
Finding a generic drive for those servos might be a problem. If I were you I'd toss the Heidenhain stuff, make some servo motor mounting adapters and just get new servo+drive sets.
I worked on a project with some Leadshine EL7-EC servos and drives through EtherCAT (although not with LinuxCNC, but they could easily be integrated) and can recommend them. Very smooth motion, quick integration and easy tuning. I also used a Mesa 5i25 + 7i76 on another project and the Leadshine EL6/EL7-RS should work just as fine through Step/Dir.
Motors are compatible with both series (23-bit encoder). Big pluses of EL7-EC vs. EL6/EL7-RS is (to me) STO. Both series are relatively inexpensive.
