You could try reducing the max_accel number.

Or try putting some numbers in the max_error parameters of the PID to limit the pid output at large errors.

Now would you say this is reasonably tuned? Don't have enough experience to judge if this will result in decent machining performance.

No, you need _much_ more FF1

(or set the OUTPUT_SCALE to mm/s at 10V) and FF1=1.000

If you reduce the OUTPUT_SCALE to an appropriate number (say about 400)
you would need to reduce the PID terms correspondingly (to say P=220 =11000*400/20000)
etc

/EDIT Didnt respond to last message. Disregard....

Assuming a metric machine based on the 136 in the preview, and the suggestion that this isn't a room-sized machine..
In one of the Halscope traces you have have an error of 0.015mm during a move. That's pretty good. But in others it is more like 0.5mm, which is terrible.

Ahh was wondering why my numbers where that high, thought ff1 was in mm/min.

What do you mean by 136 in the preview? The 0.015mm is my bad had the mouse hovering over a lower error value. Basically it is pretty bad. Will post some beter examples of f.error and feed later.
Now in my understanding the way to reduce the f.error is by increasing P, or are there other parameters that infuence it?
