After a trip to the Reading Hackspace and a few hours with one of the excellent soldering irons they have I’ve made short work of the two dual stepper motor controllers for my 3d printer.  The only components missing are the drivers which are ESD sensitive so I’m fitting once the main controller board is complete and all three boards are ready to be fit to the printer.
