Printerboard
You will typically find this 2A 2B 1B 1A or B1 B2 A1 A2 on the printerboard. The meaning of marking is not uniform but I dare say:
- The first character typically is the coil / phase numbering (Very important, since mixing the coils usually destroys the stepper)
- The second character is the polarity (less important, since it can be reversed in the software)
This means:
- Pin 1 and pin 2 are a coil
- Pin 3 and pin 4 are a coil
Stepper motor - How to identify a coil pair
Apart from the data sheet, the easiest and most secure way to identify a coil is:
- Spin the spindle between your fingers, remember how it feels
- Short two of the wires
- Spin again: If it feels harder / more bumpy now, you have found a pair
With a voltmeter:
- Between a pair you should have some Ohms resistance
- Between a non-pair you should have infinite resistance, i.e. no continuity

This means your new 2m cable should match just nicely.
Side note:
Rated current (= max current) of this stepper is given with 1.5A →
run_current = 1.5 x 0,707 x 0,8 = 0.85A
Klipper uses RMS current as run_current

I really do not want to be rude: What we are discussing here are very much basics. Unless you have a bit of experience in this, the Vorons are not exactly what I’d recommend starting with.
