Hmmmmmm - plate sounds a bit inflexible - what are you hinge arrangements, or is it flexible in some way?
Anyway - with the e-nable fingers the pulling string is almost always offset from centre - so when pulled applies an asymmetric force around the fulcrum and hence the bend in that direction.
I have played around with this - the further away from the fulcrum you place the string, the stronger the pull force, but the lower the potential overall movement.
I have also played with non-linear 'holes' for the string - placed closer to the fulcrum, so when the finger is flat it takes a degree of force to pull, but as the finger bends the string can rise in the elongated 'tunnel' improving its force characteristic. The point of this was to vary the hole shape in each finger and thus control which bend started first.
Pop a piccy of what you are trying to do if you want and it may be clearer.

Here comes Cura 5.9 and in this stable release we have lots of material and printer profiles for UltiMaker printers, including the newly released Sketch Sprint. Additionally, scarf seams have been introduced alongside even more print settings and improvements. Check out the rest of this article to find out the details on all of that and more
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
