Hi I’m look for a wiring diagram with in the stepper motor plug so i can make a rotary cutter.

Thank you tom

When I built mine, I just took off the cover of the control box and looked at what pins of the D-9 connector were connected to the stepper motor driver A+ A- B+ B-

I used something like this for the rotary:

I also connected the rotary to the X - axis of of the control box with a D-9, A-B switch.

I’ll try to grab a picture this weekend…if I forget just poke me again.

I use fusion. I use a technique similar to this for tube notching Fusion 360 - Unfolding Sheet Metal Tubing - YouTube

Here are some pics:

Here is my DB-9 A-B Switch Box. Recall an A-B box connects either all of A’s or B’s 9 pins to the 9 pins of the output. The red X is the A-B box velcroed to the table. The red circle shows the output connected to the X axis connector on the table controller. One A-B input goes to the X axis motor connector (that comes with the table) the other goes to the rotary’s stepper motor (I don’t have it connected in this picture as I had the rotary put aside for awhile).

Here is one picture of my rotary and the stand. Note the red circle, this is a 3D printed part with cheap bearings to guide long pieces. Works surprisingly well.

Here is one more pic of my “quonset hut” leveling stand. I call it that because it was supposed to be a temporary prototype and of course I never changed it :slight_smile:

Side note, you can also see big pile of magnets in the last picture on top of the rotary…One of the best tools around…I have them all over my shop…Seriously try them.
