Aluminium profile CNC

656usd is amazing!

I agree.. take it before he finds out that he calculated wrong :D

Just a reflection.. with that long ballscrews and direct couplings the motors will stick out in the back/front where you have mounted them.
Have you thought about using pulleys or shorter ballscrews?

It seems a very good price to me too :)

Nr1madman, yes I plan to have motors on front of the cnc. I would like to have the maximum length. I could have miss something, is there any advantage to use pulleys?

For me with limited space a pulley system is good because you can fold the motor into the machine area so that it doesn't stick out.
Also it's said that the belt in a pulley system helps with resonances. Of course you need good pulleys without backlash like htd:)

Yes, resonance is better with pulleys in there, you can also easily tune/change the ratio for speed tuning.
