This is a nice little precision pump and controller combination. It can dispense 100 ml/min at 300 rpm. I set the output to 1 amp and use 16 micro steps (set dip switches to 16 and F09 to 160). I use working mode 3 (F01 to P03) and a low acceleration (F12 to 003). There really is not a good way to use the supplied mounting plate. I tapped into the nylon and used four M3x6 screws to attach to the printed mounting plate. May not need to tap if you are careful. OpenScad file included.
