New CNC router 8x4 For Cutting Multiple Materials

[Jonathan]

been working on different ideals as you can see from by thread, but seam like almost no one is willing to giving advice or the own views, i welcome anyone who can talk from experience, good or bad,

I'm happy to comment on the new design, but I haven't posted as most of the things I have to say are the same as what I said in post #7. The main problem is still that the gantry is far too tall - it's best to have no gantry sides and lower the bed, that way the gantry is supported by the main frame not some flimsy bits of plate.

A 3Nm nema 24 motor is plenty for the Z-axis. Also, to get anything like good resolution on X and Y with rack and pinion, you'll need to have two belt reduction not one. Search on the forum for rack and pinion versus ballscrews and you'll find plenty of relevant information.
