BIGCNC - small update

Hi all,

I made some small progress in building Z axis for new CNC. Sprocket on ball nut installed, holder for step motor installed.

Sprockets

Hi all,

I have to get almost 11 sprockets to my BIGCNC. Two of them will be big (48 and 36 tooth). I decide to try to cut them myself. I found a script on Thingiverse (link) and create with it one HTD 3M and HTD 5M sprockets. With Cambam I convert STL to DXF and prepare files to cut. Each sprocket is made from two identical parts and put together with 4 screws.
This is what I receive. Assembled HTD 3M 20 tooth:

Big CNC - first look

Hi,

Yesterday I made first try to try on big CNC in to one piece. It look awesome:

Only step motor is missing in Z axis.

Now it is time for X and Y axis.
