Mini wannabe datron build

neeeed jerk controllll.... hahaha

4th axis!



So, in redoing linuxcnc and adding this new leadshine L6 servo, ethercat is not totally ferked. I am getting random limit and joint errors during program runs, during jogging, sitting idle. I managed to see one of these errors with the scope and it is a one frame spike of ferror that's seemingly infinite value.

What the heck is going on. Ill upload my config files shortly. Every camera cut in the video is a random joint error on a random axis.

I have the jitter fix build, and not a whooole lot else really changed from the last build. HALP!

there have been big changes.

follow the updated process and also the added Hal file command mentioned in response to your other post
 

thanks, ill look it all over in the morning.

Alright, the 4th axis joint error inverting is 32 bit count roll over.

I am getting confusing info in my searches, but there seems like there is a hall function to manage this? Anyone have some insight as how you implement it?

thanks!

I'm not sure on this but I thought there was a change to support 64 bit floats for instanceslike this that managed the wrap but I have no experience. There is a big body of work pending in master branch around 64 bit pins. Message Grandixximo on Discord.
