What tricks have you found to reduce seam bumps?

[hackinistrator]

many times seam bump is generated at the start of the loop .
also there is no retraction at every loop end (unless you force it)
in those cases i use layer start script that retracts very little at the start of the loop (outer perimeters first)

@hackinistrator Most slicers would have a retract on layer change or retract on travels setting as well to facilitate that.
