This is my initial design for a 1200mm x 2700mm cutting area CNC. It is simply a scaled up version of the ox with a SHS & EA steel bolted table as a starting point. What are the issues I may run into with this method? I would prefer not having to change the design of the plates to avoid any issues.
Do I need to upscale the x gantry to 2 x 80/20? It is currently the standard OX 60/20. If it was to change to the larger v-slot then I would have to modify the design of the plates.
I will use 2 80/20 v-slot connected with double t nuts + fixed under table with a equal angle steel for the Y axis. Y axis is going to be rack & pinion.
Is the table too lightweight?
Nema 23 for X and Y.
Nema 17 for Z.
The location of the Y axis v-slot in relation to the table surface may be a bit low compared to the OX?
