This is a general question for reducing vibration sources. I think that even without going into detailed laws of physics it is clear that each printer is producing vibrations that can influence the quality of a print.
The moving building table plus the moving printer head produce vibrations because of the necessary stop and go motions during the printing process.
Although the Proforge2S has two support beams from the top to the base, I see two points here:
#1 - The support beam is just a flat piece of metal, would it not have been better to use a profile (more rigid than a flat strip) here - any suggestions for a mod?
#2 - Is it really a good idea to put two spools of filament on top of the printer, where they are bound to multiply (moving masses) the vibrations of the printer - any suggestions for a mod?
It would be great if we could start a discussion here and I am looking forward to hear about your thoughts!
