TopsCNC : HEAVY
Description
After the first version of the TopsCNC, I wanted to go even further by creating a heavier and more stable CNC machine: the TopsCNC Heavy.
I stayed in the same spirit as the TopsCNC, using easily available components suitable for DIY manufacturing — such as V-Slot aluminum extrusions and T8 trapezoidal screws, combined with standard electronic components (Arduino + GRBL).
Evolution
As with the TopsCNC, there have been a few iterations and upgrades on this Heavy.
- The base version is the "NEMA 17" version, with which I had satisfactory results. If you plan to make a machine of 1m - 1.2m and more or perform machining operations that require a bit more torque, you should take a look at the Heavy Nema23 upgrade.
- The improvement of the "locking" of trapezoidal screws (compatible only with the Heavy Nema23 version).
- The "MoreDepth" version, which allows for a taller Z carriage and more cutting depth.
