This is a conversion i made to a commercial peristaltic pump to accept a stepper motor.
It was easier than editing the whole firmware in order to use it properly.
it can be seen working here:

Its a simple geared system so there is alot of backlash but its not made for precision dispensing.
The secondary gear has space to press fit 625zz bearings. Modification on the body of the donor peristaltic pump is needed in order to fit the gears and drilling the base for the shafts. Also some pieces of 5mm shaft are needed.
This project was over a year ago so i'm missing the original assembly files and i don't remember specifics like the reduction rate etc..
