Hi, I am planning to create a twist tie machine that secures spools of cables. I have only found one other person who's made this through arduino boards, but they didn't provide much info into the process. I am not sure how to program for this niche project.
I have done other arduino based projects like building 3D printers, but there are many resources for that topic so its easier.
Any advice is welcomed.
Sort out the mechanics of how this will be achieved and build it - you’ll then know what the code must do.
With all these projects the hardware is the difficult part - you might even find you dont need the Arduino !

That is question 3.
Question 1 is how can a machine secure spools of cables with twist ties?
Question 2 is what function would an Arduino have in that machine?
Question 3 is how can I program an Arduino to perform that function?
And question 0: who is for ? For yourself easy , for others - packaging , maintenance , safety ( keeping figures out ) , product for sale ??

Give more details on how this machine works, and show an image or link to this project from "another person who's made this".
Is it something like this

Yes, exactly. But it must tie around the cable from a vertical position as the spool is sat flat.
This is similar to what I am interested in making, it may give you a better idea of the concept.
It is for a university project that could be used as part of an assembly line.
Yes, exactly.
Take a look at this video. I'm trying to make something similar.
Yes, but as others have said, the arduino operation is the least important. Mechanics are everything. Balers have been tying hay bales for 100 years (and then tossing them into a wagon) using only gears, springs and leadscrews: no electronics. Figure out the mechanism then come back here when you need to program it and we'll help.

Take a view here to find the best hardware:
You say University project ?
Is this part of a qualification you are doing ?
If so you need to research this stuff as you need to justify choice you make in your report , “ I asked in a hobby forum” =0% fail.
Inspiration from others is not cheating. I'm not asking someone to do it for me, I'm asking for advice. I have almost completed the entire mechanical side of it myself now. I do not do electrical engineering or robotics. That is just an extra optional step I'd like to achieve. The task is to design it but not necessarily program it.
Disagree. It's all in the framing.
"I asked hammy in a hobby forum", provide link, teacher sees hammy PFP, doesn't dare give any mark but 100% success.

Then the only addition is: 1. powering the moving parts. 2. monitor and control the timing of the moving parts. Once that is done you can think about programming the entire operation.
