Hi Laserwinkel,
I am building my own.
At this moment i have a bought machine, it's doing 32x27,5x7cm but last week when i was sick at bed with backaches, you start thinking and i almost bought one, but that dude seem to be some sort of conmen'ish type, letting you wait very long selling broken stuff.
So now i have decided to built my own.
It will do 110x550x15 or something like that.
Will start welding the frame in a few weeks, and order the stuff i need in the next 2 months.
In the mean time i am learning stuff on my small machine.
There is lots of stuff to learn you know, router bits, software, material stuff...
Hopefully i will be able to engrave cool stuff, make my own front plates, and coolingblocks/cases.
I didn't fail !
I just found out 10,000 ways that didn't work.
