Design of a gantry system for my DIY CNC using Rack and pinion
I have recently implemented a DIY CNC based on a 60x40 RHS as a guide rail and 4mm metal sheet used to construct the gantry on belt drive system, I now waned to change this same system to rack and pinion with a 8 to 1 gear redaction to multiply torque
The pinion on the reduction box has to press down to the rack with spring tension
Please refer to the attached documents and video link for details

what I needs to change on this design is the X-axis RHS needs to change to 50 x 70 RHS instead of 60 x 60
I have attached the drawings for the system i am using now, I can provide the original DXF files when agreed
