Creality Ender-2 Base Plate by lewtwo

My problem with the “Y” AXIS turned out to be the location of the “Y” end stop sensor switch. I had it in the top slot of the “Y” AXIS extrusion. It belongs in the bottom slot. It is the back wheel of the carriage that is supposed to trigger the micro-switch. This is a complete rework. My mistake, my ignorance, my apologies.
Moving on ....
I still want to put a larger base on the bottom because my printer sits on top of four vibration
dampening pads to reduce the noise (around 25 db at this point) and is just a bit tipsy when I hang a full spool of filament. In working on this project I managed to strip the socket of one of the 5mm button head mounting screws. In order to remove that screw I had to totally disassemble the entire printer down to the bare acrylic base plate. The add on board will also allow enough thickness to replace the 5mm button head screws with proper 5mm x 10mm long socket head cap screws. It should be obvious but never assume: the two drawing are from the bottom looking up.
I am attaching a piece of 8mm thick compressed bamboo plywood (3 plies). I selected three points for 5mm mounting bolts and use 5mm diameter by 8mm long “T” nuts in the plywood. This allows me to bolt the printer to the “add-on” board from the top. The clearance holes in the plywood will be “match drilled” to the acrylic plate. The location of these pads was chosen to allow the printer to sit on top of a wooden box that houses the power supply. I got the anti-vibration pads via Amazon.

I am old, senile (as demonstrated by mistakes on the first version) and must be going blind as well. I made this as close as I could measure but I certainly would not bet the farm on it. I included the PCB holes but I do not have enough confidence in them to include full dimensions.
