  • Y-axis linear rails are side mounted to the 160x80 item profile. This allows a larger work area and the ball screws can be mounted to the same piece of aluminium plate, with a little bit of machining.

  • Gantry side plate is on the inside and an 80x80 item profile is mounted on the outside of the plate. The 80x80 item profile is mounted to the X-axis 200x80 item profile with a back plate and a bottom plate.

  • The X-axis ball screw and linear rails are all on the front side. With some machining on of the aluminium plates, I am able to squeeze everything in the with custom made ball screw nut brackets.
