It means, "Not a Number". That is not good. We used to have this problem
several years ago with communication between the real-time and non real-time
processes. I'm glad you have a stepper system, on a servo machine one or more
axes take off at warp speed toward the next galaxy! This is an important
problem and it would be great if you could determine what G-codes caused it.
Just a thought, you're not using the R format for G02 and G03 are you? You
are using I J right? The reason I ask is that this problem (screaming
runaway) was also caused by subtle errors in programming arc moves using R
format. Thanks for reporting this!
