Hi,
I've just starting running my first code to test a new build. I've noticed even after adjusting motor tuning and CV in mach3 and slowing the speed i'm getting too much vibration through the framework.
In-hind site I should have used a bigger profile steel, 4mm wall thickness etc as the electrics are producing plenty of torque to move a 50kg gantry etc.
I've designed the framework to be open both ends and for the work bed to be raised and lowered to allow for blocks of foam. I'm just wondering where to start adding steelwork to dampen the osculation, particularly when the machine changes direction.
Sorry about the pic, produced in NOCAD ;)

I would do them in the order C A D
With the A bracing it is better to go from the corners instead of midspan as these are stiffer.
The above would help with the visually detectable shake. The rest are more likely to improve tiny vibrations that effect surface finish so for what you need might not be necessary.

Thanks for thoughts.
I concur. C is the priority, The X rail needs support in the middle and the A diamond provided that support. I think there is also some work to do on to gantry legs to get them absolutely square to the beam. Even a very slight parallelograming is creating a tension in the structure and i'll need to get rid of that. Watch this space :)
