@deckingman said in Input Shaping makes no difference whatsoever:
@mrdui I have a theory which is purely conjecture, and based on two things that you have mentioned. Firstly that your print head has a mass of 8Kgs and secondly that you only see the artefacts when printing detailed parts. So it could be that small, probably segmented moves, start and end at some micro-stepping value in between full steps.
Sorry I should have been clearer: ringing only bothers me when I do details parts because the goal of detailed parts is usually to get a good aesthetics result.
But most of the time I print functional parts so I just don't care about the appearance, My only concerns is for the parts to be mechanically sound and to print as fast as possible. But the ringing is the same no matter what parts I'm doing, even when the parts are gigantic.
Out of curiousity, what is this print head that has a mass of 8Kgs? I have a 6 input, liquid cooled hot end with parts made from stainless steel and brass as well as aluminium, mounted on a metal gantry between two parallel rails but that only has a moving mass of around 2Kgs. Above that, I have 6 extruders mounted on a separate gantry (the UV axes) which weighs in around 3Kgs. The combined mass of both gantries is around 5Kgs so I'm curious to know what your configuration is that has a mass is 8Kgs.
Actually 8 kilos is the mass of the whole gantry system, so thats the carriage itself, the tubes, the linear bearings, the rollers and the motors. Basically everything that moves, besides the bed. The carriage just by itself is more around 2kilos.
Here is a link to my build thread, in case you're interested to see: https://forum.v1engineering.com/t/mpcnc-made-in-china-new-build/19393/508
Most of the weight actually comes from the metal tubes which are very heavy duty industrial smooth rods. Reason being that I was using the previous version of this machine as a CNC router too.
