Hi All - I have been researching on and off this subject for a while. Been 7 months since I've spoken about jerk here. I have started a collaborative design with a company for a large router (3mx1.5m) and they want to use servo motors and run fast. So I dug out my notes and did a bit more digging on controllers. I found an old note about Dynomotion and started reading their stuff. I also sent a note to Duet3D and started reading their stuff. I found Duets docs and forum was like walking through mud. However Dynomotion was clear and happy. Plus Tom from Dyno answered an email even though its Easter... I like Kflop and its now the front runner for the AA machine. Good diagnostic software and jerk control to boot for steppers and servos. Shall know more after reading more. Its also open architecture so maybe able to write an input shaping or active control for it... Have to brush up on C. Peter
