Hi

Take out the steel plate, is acting like a trampoline, oscillating with the machine movements!

Is the machine leveled OK? The installation guys use 0.02/1000 Spirit Level ( leveler )? Let the machine on the concrete floor, try first on the top of rubber, if not cutout rubber around legs!

good luck!

Thanks FCM,

we remove the metal plate and make a new ferro-concrete base.Under foot put ESD rubber.Now machine working perfect - without any vibration.

Thank you very much and success.
