It is recommended not to use cheap chineese wires as:
– Cheap wires are thicker, takes up more volume on the drum, which increases the risk of “wire jam”.
– The lifetime is better with quality wire.
– It is easy to spice, you can use a piece of welding wire a slicing tool.
– Requires more power from the sled stepper motor
– Generates more drag in the air, which means less altitude
Use Liros DC500.
It is a quality wire, which costs around 500-600€ for 1000m.
We have also tried Liros DC Pro that is only Ø1.6mm, and it is still easy to splice.
