FIGHTECH is still alive

Hi all,

Figtech is alive. I did not forget about blog, but currently I have moved to new place and workshop is not set up. I hope that before Christmas I will show some new pictures.

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.

Big CNC - update

Hi,

I made some progress in building newest machine. Z axis is ready in 85% now.

New status

Hi there,

As I was better almost all previous week I was working in my workshop. I decide to do as much as I could in this time. So there is a lot of progress.

This is frame of new machine, it will be total 1850 x 983 big, and 700 mm high. It should be build like that, because I need someday to take it out of this room. And only 790 mm wide doors are available.

Ball nut and screw for Z axis

Hi there,

I am ill still and can not do anything in workshop. But I received one more thing to new CNC. Ball nut and screw for Z axis. This is 1605 screw, 200 mm thread long. Already prepared to install. But first I have to project and cut out parts for Z axis.

Only Z axis will have a screw. Rest of axis will be belt driven. I think I will use HTD 5 belt as a direct transmission for X and Y axis. I like to have a fast machine.
