Hello from Derry!

[JAZZCNC]

Well you have one of the better ones which uses water cooled spindles but unfortunately using the TB based drive which is not so desirable.!

These machines are OK for learning but if you try to push it too hard then it will break at some point.
If you can't return it then my advise is use it to learn on. Don't expect the world from it, treat it gentle then sell it at your soonest opertunity.
Then either buy or build a better machine. DON'T try to upgrade or make it better you'll just be throwing good money away that can be better spent on DIY build worth having.!
