Aluminum CNC , iD2CNC - SS v.1.0 Build log

[lucan07]

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.

iD2 What are the yellow bits for on the back of the motors? if they have any weight they will certainly compromise the machine with the extra inertia.

Looks cool. Practical if you need to manually move an axis. Just don't rotate too fast because the motors work as generators as well, and will feed back currents the wrong way. Depending on your stepper driver, it may cause harm if you rotate the dial too fast.

Do you really feel the need/use of dampers? Have you tried with/without? OK, it came with the machine, so no reason not to have them, but I am curious if they are actually doing anything useful.

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.?
Back in stone age it was common Hack to get around resonance crippling performance. It's not a Good thing.!!

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.

Although the single X ballscrew, gantry side plates and overhanging Y axis (due to ballscrew position ) will reduce stiffness and performance my experiences of this type of design is that it is no problem for wood and plastic and will cut them all day long. If that is the intended use the I see no great issues on the mechanical side
Occasional aluminium plate is ok but for serious aluminium work this is not the machine to use and you need something stiffer in design including profile rails on most/all axes
