Arduino_WireCutter

Arduino wire cutter stripper with nextion display

I'm not a professional. I've worked on my own personal 3d printers for awhile so I'm familiar with arduino and steppers. Never have I done a project like this so its my first from start to finish. I basically saw Mr Innovatives video and wanted a machine similar, but no code or layout was provided. I've made some very simple 3d drawings for the supports and during my trial and error build I decided limit switches where the way I wanted to go. This way I dont care about steps when it comes to cutting the wire (other than feeding wire). My first nextion HMI - lots of hardships getting through it and the arduino code, again I'm no pro by far. I'm sure there are alot of things that are questionable and/or not correctly done, but I went with what I could figure out. Please feel free to contribute to the code, if you want to collabrate on this let me know and I'll open the door. I can be contacted through garzajd3@gmail.com or message on github.

In the pics below is my version of this tool. I went with adding limit switches on the "cutter" stepper so that I do not need to actually know the # of steps for a close/open. There are a total of 5 3d printed parts: 1 for the feed stepper mount, 1 for the wire tube holder (adjustable to align with cutter), 1 cutter holder, 1 piece the holds both limits switches (mounted to the cutter stepper). I've also opted to use a 5:1 stepper for the cutting unit. I was finding that with a standard 1:1 nema 17 sometimes steps would be skipped when trying to cut wire. I'm sure this can be worked out by adjusting linkage, position, etc but I wanted something that would work consistently with alittle more power.

Sorry this pic is blurry, but it was the only one I took. This is the simple PCB I laid out as a UNO plug-in (shield) for the stepper drivers and connectors. I probably went overkill on the components, but oh well.
