A couple of years ago I started a thread about printing my own peristaltic pump. The intention was to follow through with a controller for coolant and air. The project was shelved through illness and now I am better I am picking up on unfinished projects.

I have all the kit I need to make a step programmer that at each step delivers air, coolant or both. I thought about 16 steps at first, but that is way OTT so 8 channels.

I will carry on with it one day, but I have other projects to clear first.

The reservation I have is that peristaltic pumps need a soft silicone tube. I have been informed that silicone tube is not oil resistant _ any advice please !

Cheers
