That’s not going to make a difference. The big supports you created only touch the print at the very top, the last layers in the print. Up until that point, the support does nothing because it’s not touching the model in the area where the printing is under way. Some of your examples show shifts throughout the model, not just at the top where these supports will help.
I just saw your next post. OK. By “vibration” you mean the ripples in the surface of the print. Again, it has nothing to do with what the printer is sitting on. Desk, floor, a chair, as long as it’s flat and relatively stable it will be fine.
The ripples occur because the print is not touching the same locations from one layer to the next. Something in the mechanics of the printer is shifting. The build plate is the first thing to look at. If that is tight and doesn’t move even a little bit, the next thing to look at is the LPU. Other than a shifting build plate, the only other explanation I can think of is too much backlash or sticktion in the X-axis motion system. The jack screw for the LPU X-axis may need cleaning or lubrication (I think FL has a procedure for this).
Like I said, my Form3 isn’t on anything special, and it doesn’t do this. So what the printer is standing on probably doesn’t explain your problem. The issue is inside the printer, not outside.
