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!
Best, Eduard
The beams work well to create a triangle shape to keep everything rigid despite being flat themselves. We did include some mounting holes on the beams, they could be used to fix 2020 extrusions too.
Adding more weight to a printers frame would usually help dampen vibrations, but I see where you're coming from, you could try printing some table top spool holders and comparing, but this was never really an issue when designing for vibration reduction.
The two key things that were included in the design to reduce vibration were the TMC2100 stepper drivers and silicone rubber feet.
The only real vibration on my printer is caused by x movement.
I‘ll be putting a vibration dampener on that motor and hope it helps
