From Updated Marlin, now moves are not smooth
Jeffeb3: Why did you only upgrade to 414D? I think there were some junction deviation/arc things getting worked on then. I forget where it ended up, but I think the more recent 425D versions have that ironed out.
(Sorry, I haven’t figured out how to quote from another thread.)
Is 414 the latest/last firmware rev for the MP3DP? Or is there a newer one with similar fixes?
