Hi Everybody,
I have an idea to build a "Cable Length Cutting Machine" using for following:
*Arduino Uno
TB6560 Stepper Motor Driver
Nema 17 Stepper Motor
Basic Display
5 Off Push Buttons:
Start
Reset
Increase Length (mm in multiples of 10)
Decrease Length (mm in multiples of 10)
Cut Cable
I have the design idea in my head and how to build it, just unsure how i can code this and get it actually to work. As i cannot find anything like this on the internet.
The idea of it working:
A cable is placed in one end where a stepper motor will feed the cable to the desired set length, once it reaches this set length i then press a button to cut the cable and then press start to start the process again. There will be one stepper motor either end so once the cable is cut in can still be fed out of the machine.
I would REALLY appreciate any help that you can give me Thank you in advance !!
What part are you struggling with? and can you clarify why you need a second motor? I saw a few wire cutting machines in my life and all of them just feed the wire out, cut it and let it drop in a container
The need to push a button to cut the cable seems pointless to me. Why not have the machine automatically make the cut at the right location? I'd make it so that you can set the length and the number of pieces to cut, hit start and the machine does everything else on its own.
I bought an old programmable wire cutter on Ebay several years ago. It's stepper motor has a wheel with grit embedded in it and has a rubber wheel pressing the cable/wire hard against the stepper motor wheel, so there is limited slippage. The machine has only one stepper motor and works just fine.
It also has a low voltage solenoid do drive the cutter. It is powered by a capacitor charged to a high voltage and discharges into the solenoid to give a very quick and powerful cut. Makes a big bang!
You just need to measure the drive wheel circumference on the stepper to get the cable length moved for each step and you are ready to go!
Thank you in advance !!
