For test cut aluminum , yeah i already test cut it after finished build and it can cut aluminum but with this design it not good for metal work or aluminum work.

Amazing how someone videoing a machine test completely omits the machine, could have been any machine and not necessarily a very good one in video, nothing suggests that this same machine, or that it is stable, could be the gantry swings like a pendulum so you don't want to show it even long shots take care not to show enough of machine to identify it.

:D , Sorry for not do video review machine first and it not swings but it vibrate.Quote:

That was dampers , it come with stepper motor.DampersQuote:

I've not read your thread bit if you have bought a complete machine and it came fitted with those dampers on then it suggests your drives are not the best and affected by resonance.?Quote:

If not and the drives are of decent quality with Mid mad resonance damping capabiltys then remove them because they will be affecting performance.
A quick scan of the thread points out he's actually trying to sell the plans and parts to build these machines, apparently they're the best thing since sliced bread, glad I bake my own.
