Dedicated printer table for mini
How sturdy should the table be for a 3D printer, assume if the table moves or wobbles this not good.
Im thinking of making a dedicated table about 2ft tall out of 2x4 wood with a 1/4 plywood top. I think this should be ridged enough. I was thinking of adding a concrete slab for the print to sit on also but not sure if thats needed.
Any input from anyone with a dedicated table for there 3D printer would be good.

RE: Dedicated printer table for mini
You don't want anything wobbling about, but you also don't want excessive noise. The vibrations from a 3D printer can easily be picked up by a large, flat surface and amplified through resonance. Definitely consider adding a weighted based (e.g. paver tile or marble cutting board) to any lightweight table or cabinet you go with. You want to couple the printer to the base mass, so use something like felt feet that don't isolate the printer from the mass of the slab. Then you want to de-couple the slab mass from the table surface, so use something like foam or Sorbothane feet.

Thank you thats some good advice. I need to start a shopping list on amazon now 🙂

What is your opinion on the foam pads included with the MINI+?
My setup is: carpet floor → Ikea LACK table → Strips cut from an old mousepad → 44 cm paving stone → Prusa MINI+ (with incl. foam feet)
Adding the paving stone definitely makes it feel more solid, but it hasn't entirely eliminated noise from resonance. I am now wondering if replacing the provided foam feet with felt would help at all.

Most people have no trouble with resonance/vibration, they happen to choose a site that does not resonate. The simplest way out is often just to re-site the printer.
If that is not possible then find ways to change the frequency of the supporting furniture: adding or removing weight, increasing or reducing stiffness (aka strap down the noisy bit) or change the source frequency (change printing speed) - or a combination of these.
Failing this then vibration/noise absorbtion, thick carpets, curtains and soft furnishings.
Paving slabs are just one way of adding weight.
Cheerio,

I have another question in the same theme: Can you put a Prusa MINI+ on any desk ? If not, what does it need ?

A firm level surface, is best
