mini CNC project[300×300mm] based on 2020 / 4020 - alum. X-profiles

EN

That is my “redesigned” idea of mini CNC router. All parts where ordered from Aliexpress or Ebay and it was not so much as cost actually.

The project took few months to assemble and to get all parts. The result is quite average but not that bad.

Axis movement is smooth with that rollers, but not very strong in that setup. If you wish to have stronger base, then your design must be with only big V-wheels, made from strong ABS plastic and maybe few of them on each side as the developer from OPEN BUILD make.

Additionally to the build is small holder for dremel type grinder, one 3d printed holder for small 18V motor used as spindle and one 3d printed holder for 3.5W laser like that:

The GRBL board to drive machine that is my design, because after buying two ready chinese boards which has own problems, decide that will be nice to have something that if not work will be only my fault (he he..)
