Hi Amin ,
Yes I sure did . It went remarkably well . I spent some time making a better Z axis arrangement but all in all it wasn’t that tricky.
While it’s supposed to be capable of doing a 8x4 sheet I found it lost accuracy in the extreme corners such that a 20mm hole in the top left corner would come out as an oval shape .
If I did it again I would make my top beam longer than the recommended length so you can move the motors further out at a later time .The reason being that if you want to do a full 8x4 sheet then
you need to place the motors further apart than the recommended spacing to give you just that extra bit of control at the extreme edges . That makes the calibration a bit more interesting so I would get it working first and then if you want the added accuracy
at the edges then move the motors further out .
In one of the photos you can see the workbench I constructed with the top full of 20mm holes actually on the machine
It certainly wetted my appetite to carry on with CNC based woodworking , but I’m probably going to design my own Modular 4x4 vertical machine that can be expanded to an 8x4 machine by doubling
up on the base when needed. ( space limitations are always a problem )
