Scanning Z Probe Flex Cable?

charliedrums

So I accidentally broke the ribbon cable on my scanning z probe. I got some replacement from amazon (uxcell Flexible Flat Cable, 4 Pins 0.5mm Pitch 76mm FPC FFC Flexible Ribbon Cable for LCD TV Car Audio DVD Player Laptop 10Pcs (A Type) ) but now my scanning z probe does not calibrate. Did I get the wrong flex cable?

I get constant

M558.2 K1 S-1
Error: M558.2: failed to calibrate sensor drive current

M558.2 K1
Sensor drive current is 31, offset is 144968

Before the cable changed drive current read 14. Everything worked fine up until the cable changed. Maybe these cables are not the ones? any help will be appreciated. Thank you.

I think I figured it out. I bought the A type cable which the ends are in line and I need the B type cable which the ends are opposite?
Is this it?

@charliedrums You want a 4-way, 0.5mm pitch, opposite side contacts, Flat Flexible cable, eg from Mouser.
Duet3D supply 50mm and 150mm long cables that are rated for 80C.
Different lengths, and higher temperature rated FFCs are available.
