I will give that a try Rob, I don’t think it is in my ini file at all IIRC. My acceleration on the Z axis was set quite low so I brought that up to something reasonable today and it helped. Though again, it is a direct comparison as those have been my settings under the previous (2.4-2.6) releases. Will try ARC_BLEND_RAMP_FREQ tomorrow.
By the way, this certainly isn’t a “critical application” of any sort but it is interesting to “hear” differences in the new code, and learn about new options (apparently)!
