I am assembling the SP6 gears with the arbor of 1/16". By drilling the holes of the gears, I was able to push the arbor through the gears, but it is.a tight fit. Is it supposed to be a tight fit or should I drill the holes bigger to make the gears rotate more freely? When I push the arbors into the four holes on the front frame, the fitting is so tight that the arbor won't rotate. Is it correct? thanks,

This is my first time working on CNC Shield and related eletronics. I want to make sure I am doing the modfication (4 edits) correctly. Do you think you can share a picture of the backside of the CNC board after the modification? For example, I am not sure how to do Edit 2, Do i just short the four nodes on the right side, and connect the Vcc on the left to the top node on the right using a wire? Thanks a lot,

I just ordered SP6 silent desktop clock. I am wondering whether it is possible to change the display time (I, II, ...) to numbers (1, 2, 3,...)
