At 1.20 euros a meter was that for chain flex? I've seen prices for cy shielded from £0.60p per m but it doesn't suggest constant bending i.e for chain drive
I found this company at £1.94 per m for chain flex https://www.tme.eu/gb/details/cf881....shielded/igus/
or is the chain flex over the top?? and standard CY shielded fine?
