Ghosting is an artefact in the print due to the vibrations in the printer that are induced by rapid changes of direction. It is important not to confuse them with inherent vibrations in the printer due for example to the belts being loose or the bearings not being in perfect order. The good news is that it is relatively easy to tell them apart: ghosting (...

Ghosting is caused by differential movement between the bed and the head when the head undergoes acceleration. The forces add energy to a resonance in that differential vibration mode. By changing how you mount the base, you will change the mode and probably change the frequency. With the soft mounting, the bed can move more easily. It will tend to ...

To expand on the #3 solution: reducing the elasticity of the system, if you have your filament mounted on the top of your printer, placing the filament elsewhere on a separate spool holder can also reduce ghosting. Tightening the belts and moving my filament got rid of ghosting for me on my MP Maker Select.

Ghosting is very well described in the topic What causes “ghosting”?. Ghosting is an artefact in the print due to the vibrations in the printer that are induced by rapid changes of direction To add to that answer and get on topic of your question and your possible solutions I'd like to say that neither of the solutions you provide is correct. What do ...

The fact that these are all perfectly spaced, and don't mirror the edges of irregular prints, makes me think it's definitely not ghosting. That said, I can't see the Y direction on either print, just the X direction, so this all assumes it's only happening in one direction. One thing to think about: Your motors have typically 2 opposing coils, and they get ...

I got good results by mounting my printer on a concrete paving slab (obviously cleaned and sealed) and placing that on a foam mat. The combination of high mass and flexible mount has substantially reduced ghosting in my prints. Not my idea; I found it on a video on YouTube which I no longer have a link to. Honestly not sure if this is the best solution from ...

There are 3 options to reduce ghosting working on different methods. Basics of motion physics When the machine changes movement direction, it does so with a very short time difference delay between the head and the frame, inducing vibration. Let's assume the head makes just movements back and force around a point $x_0$ in the mid of the bed with an amplitude ...

To fix ghosting it doesn't realy matter if the printer is bolted down or flying thru the air. The main point is to get rid of any movement in the printer construction itself. What I mean: If you bolt down your printer, but all parts wiggle as hell, then you will have ghosting. And if you have a printer with no wiggeling parts, then the printer could ...
