Jon machine is going mint. I don't currently have encoders connected back to the control but I did. The motors are tuned mint. It's just the table mass at the acceleration jumps a bit when moved.
I might just enable reducing feed rate at corners in fusion360 cam for now if I can. I want the acceleration for a faster machine (top speed is only 8mm/min). And acceleration is only 500mm/s squared. So I don't want to go any slower in general. I just want nicer cornering like a okuma machine Regards Andrew On Fri, Jul 24, 2020, 3:44 AM Jon Elson <el...@pico-systems.com> wrote: > On 07/23/2020 12:00 AM, andrew beck wrote: > > Yes I'm not worried about servo following error spikes.
