Hello.
I am building my second machine.
Have a build log at cnczone, but i find this forum handy,
the more forum's- the more knowledge :)

Previous machine was a mdf/drawer slide machine
with M12full thread as drive screw's.. Probotix 3 axis 260 OzIn stepper set..

New machine will be Alu box-section frame with 20mm precision linear
slides and twin 20mm ballscrews on X axis with 5mm pitch, designing "on
the fly", but the other axes will be similar.
The frame is done, just waiting from the items from Zapp..
I belive they will be shipped out today :)
