Sieg KX3. Cannot accurately control spindle speed. was created by Roadwins
I got a KX3 a couple of months ago. Just not getting to really play with it. I have noticed that the spindle speed is not correctly controlled. Even in manual control the spindle speed max is about 3000 rpms and low is about 2000. I was looking thru the files and found an older setup. With that one the max is 3500 rpms and low is about 1000. I have not attempted doing my own setup yet. Any ideas on where this is controlled or where I should start? Also what should I look at to get setting and pins if I want to try a new setup? Breakout board is a cnc4pc C11G.

Thanks Pl7i92
Spent the morning playing with the spindle section of stepconfig and starting to learn how the 4 values relate to each other. I am not quite there but I am getting closer and closer.
