Here`s the code for horizontal mount sir, it starts from right to left
Note: on our machines I dont use the homing switches, I just press "ref all home" button on mach 3 to zero all axis on it`s current position, I do think that it`s easier for you to reload materials if the plastic is facing the other way around, simpler to reach the T-slot brackets with wing nuts, on sacrificial wood, a 1/2 plywood I think is good enough to put your wooden stoppers and the upside down bolts for the T-slot brackets then wing nuts for easy load and reload of the plastic boxes but of course it all depends on your preference, bottom line is you can do whatever you want with it

Nice belt driven CNC machine you got there sir our two units CNC laser machines used belts too, and it`s already 12 years old and never change the belts on it yet. I do think it`s a clever way to avoid ball screw jamming due to small dust particles entering on it causing to lose steps, for light routing passes on non metal materials I think it`s a good and better idea to use belts instead of a ball screw
