this is my remix of ProjectswithRed's automatic wire stripper. I've recreated (almost) all of the 3d models with openscad, to allow for parameter tweaking. I switched the extruder to an openscad model, and tweaked that extensively as well.
A 3D printed automatic wire stripper and cutter. I had some old 3d printers that had been retired, I reused those parts for this project. I used a mainboard from a wanhao i3, and 24v steppers from a makerbot replicator 1 (though the wanhao steppers would've been fine at 12v). I'm using a 20V 65W lenovo laptop power supply that had a frayed end.
I'm running Marlin on this, since that can already do everything I need and I don't have to write or maintain any code :).
X and Y endstops are always triggered, so G28 won't fail.
I modified the Z endstop to be optical, so that's inverted from the wanhao's config.

I used some parts from old, dead 3d printers. mainboard, lcd, and rotary encode from a wanhao i3, steppers from a makerbot replicator 1, and a power supply from a lenovo laptop that had the end frayed / broken.
-
D8mm L100mm lead screw (x2), for the linear motion.
-
D8mm lead screw nut (x2), to attach the top blade housing to the lead screws.
-
5x8mm rigid shaft coupler (x2), to attach the lead screws to the stepper motors.
-
10mm magnets (x2), to attach the container.
-
KNIPEX V-blades, to cut and strip the wires.
Please refer to the /3d_printing directory.
This is the layout of the components on the board. Use this only for reference on roughly where you should fix the components to the board. I don't suggest using this for exact measurements as you should position the components where it is appropriate for your version of the project.
