      My Overlord is extremely noisy

      Yes it is, resonance box of worst kind as all parts are loose it sounds like.

        Are they intended to be answers to the questions you've been asked? From what I see, the effector reached all positions it would be expected to reach. It's false triggering before it hits the bed, but that's not what I'd call "can not reach all the points".

        Does that video show the behaviour you are trying to correct and that you have described as "can not reach all the points", or is this supposed to be illustrating something else?

          The whole story started with false trig's and after a lot of tests it kinda worked OK then these can not reach started, now the points are reached and false trig pops up. This is a sensitivity issue as so many parameters can get to make issues like dive height I had yesterday. This is a bloody mess so I start to think there can be a problem with the board it self.

            OK, sorry I don't know that board. Presumably its running Reprap Firmware of some version, if the config is compatible with Duet boards??

            The false triggers seem to only occur during movement, not when the machine is stationary? If so, it can only be either mechanical resonances or a wiring problem with crosstalk from a power cable to the sensor cable.

            As an experiment, you could try putting some sponge rubber or wadded tissue between the sides of the heatsink and effector frame, to damp vibration without restricting the end movement on the smart effector too much, and see if that reduces or eliminates the false triggers?

            If it does, the solution appears to be to try and improve the stepper driver settings or type, so they don't rattle the whole frame??

              False trig occurs when there is NO movement, can make longer delay with M672 still false trig.

                Sorry, I'm not familiar with James. Is that from a Duet reseller?

                    @phaedrux it's bought directly from Duet3D in the uk

                    Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

                          That sound is terrible...and beside lowering the sensivity of the smart effector i would say...get some new Linear bearings...just from that sound ever time it changes direction it could be vibrating bearings that affect the smart effector

                            The Overlord printers sound like that from new; the linear guides are pretty good as long as you keep them lubricated, twin rods with long bronze sleeve bushes.

                            I've always thought the noise was due to a lack of or primitive microstepping in the control board & motor drivers, plus the long guide rod design means there can be some lateral resonances.
                            (The machines were launched on Kickstarter in late 2012 or early 2013, if I remember right, so the electronics are fairly primitive compared to a Duet).
