Does this fit the 3018 prover?

It requires you to 3D print a 52mm bracket. Ve sure to write Sainsmart for the bracket - it's a perfect fit and works with the end stops. Be *very* careful when removing the Z-axis bearings. They are 35mm bearings and are impossible to find. In fact, you should buy LM8SUU (short 17mm) bearings x 4 in case you mess up and some balls come out of the bearings. Those are easier to find. Print the bracket at least 80% solid, reassemble your machine, and you're in business. It works quite well.

does this work with the cnc3 3018 pro?

Can you send me wiring directions to the board for this unit

Will this fit your new. 4040 model

I had to purchase a new Z axis holder to use this spindle - it is not a take the old one out and put the new one in situation.

what do I use for a power source. do I just modify a wall plug cord to wire the converter?

It comes with a 3-prong power cord which you connect to the terminal screws on the power supply. I attached crimp terminals to the ends of the power cord for a better connection.
