Interesting idea!
But the stiffness may decrease.

Here is the final version using a central 250mm x 120 mm new plate.
You can see the older little one on the right side of the cnc..
The x-y max ranges are now 220 mm for x axis and 148 mm for y axis.
Everything super stiff. I have four 3d printed supports for the plate, done with 2x2060 extrusion bars of 250mm lenght each.
Time to move on new z castle and motor
:-)

How has the performance of the machine improved after using polymer granite?
I have seen many examples of making the support units of a machine tool from polymer granite. This has a good reason: granite is strong, tough, heavy, and not subject to thermal expansion.

I think there is more reason to make the table heavier. Because it resists vibration during milling. https://www.cnc-club.ru/forum/download/file.php?id=182699&mode=view&mt=1

I was planning to install a ball screw too. I even noted it on the seller's website: https://aliexpress.ru/item/32937764146.html
But I read many comments that Chinese ball screws do not offer advantages over trapezoidal screws. At least for low loads. They also have backlash.
What advantages did you see?

Hi Chris!
Interesting upgrades!
I deleted my Facebook account because it takes a lot of time :)
But apparently I'll open it again.
