Thanks Jules. I don't have anything labeled acceleration in the speeds area. Is it referred to as something else? Screenshot attached.

How can I reduce the acceleration rate in S3D? I'm having a similar problem and have seen that suggested here, but don't see that setting. Also, I've got several areas that I can configure a retraction. Where is the best place in the settings for changing retraction between layers?

Does anyone have the link to the printable replacement parts mentioned here? I'd love to have that before I need it.
