I was reading about the A1 and problems with bed-slingers printing tall models because the moving bed tends to make the model wobble and layers can shift or the model gets knocked down.
That got me to thinking about core xy and tall model problems. Most of the problems that I have seen are caused by using infill that overlaps and when the model is tall the nozzle hits the infill bump and knocks it loose.
Now to the point about anti-vibration feet and tall models. Anti vibration feet do not stop the printer from vibrating. In fact, they let it vibrate more. Their purpose is to isolate the printer vibration from the surface that it is sitting on.
Depending on how soft the anti-vibration feet are they could allow the printer to vibrate enough to make a tall model wobble and have the print fail just like a bed-slinger. The perfect solution would be to bolt the printer to a large block of granite so that it is so solid that vibration is at the minimum possible.
