CNC 3018 Pro Upgrades

CNC 3018 Pro Upgrades

These few details allowed my cnc 3018 pro to become more rigid.
Now it can even process aluminum (not large parts).
This design is not perfect and I have thoughts to improve it.
In the next version I want to do:

1. Round shaft made of standard iron pipe (outer diameter 22-32mm).
Now it’s a clothes rack divide (it seemed to me beautiful and reliable, it was a spare from the old closet).

2. Reinforce lateral holders (now their thickness is 10 mm, they deviate by 2-4 mm when moving the tool along the X axis).
I think may be can add an iron corner.

3. Adding "bushings" for the shaft to get rid of micro jamming (braking when moving along the X axis).
Now I have made a crossbeam and fixed it with screws.
See photos and STL files.

See how I collect it (I think to understand, knowledge of Russian is not necessary).
