Building 750mm x 750 OX. Won't bore you with the traditional, just the mods, extras that may help make your better.
Cable management was important to me. I used a 10mmx10mm drag chain to get all the wires from the gantry to the left side. I have attached a 3D swivel to attach the chain to the gantry using an existing hole. I drilled a large hole between the two holes in the 20mmx40mm horizontal to get the right stepper motor leads to the left side without hanging it on the beam.
I used high wear nylon wire mesh to ensure long wire insulation wear.
I drilled and tapped holes on the gantry and two side plates to attach limit switches on the x and y axis (both + and - limits run in parallel). I tapped them because there isn't enough clearance to get a nut on the inside.
I terminated all my wires with 16mm aircraft connectors, both 4 wire and 2 wire.
I will builda housing for the xPro and spindle controllers all coming out through these connectors. My plan is to be flexible.
I built a connector holder on the gantry (.stl included) so that my spindle can be swapped out of other effectors can be added (like a 3D extruder).I also pre=wired a sensor connector in case I want to look into probing.
Not happy with my current z-limit switches- I lose about 40mm of travel. Stay tuned for an update.
UPDATE: 2/2/2015: Repositioned my z-stop (took a little engineering, but I recaptured max travel. Will post pictures when I actually get stops to work.
Finished my electronics mounting box and recompiled to enable VARIABLE_SPINDLE speeds. Also, set my max speed in config.h to match my spindle. See pictures. I'll link to the 3D files in parts list...
First run. Drilling pilot holes for spoiler Board:
