I would look at I.V. pumps as well, can usually pick them up cheap from surplus.

DIY CNC Glue Dispenser Hi all,
I'm studying Mechanical Engineering part time and I have decided to build a CNC glue dispenser as a project and for my boss. Things are taking alot longer than I thought they would and I now have less than three months to get this done!
To begin with I was going to build this completely from scratch but now (for speed) I think the best option would be to buy a basic kit and modify it to suit.
The plan is to build a small 3 axis bench top type machine. There will be a syringe on the Z axis attached to a precision air control unit.
The big question is: How do I control 3 axis' plus the on/off of the air control? Is it a case of finding the right chipset?
Has anyone done anything like this before?
Any help would be much appreciated. I will try to post up some pics along the way.
Thanks
Lee

Sorry I forgot to mention that I already have a precision air supply which I intend to use to force the glue out of the syringe.
At the moment it's a hand held device and is switched on and off using a foot pedal. I want to be able to switch it on and off using an M Code during the program.
So instead of the pedal I assume I would connect it to an auxiliary output on a CNC chipset?
We had been using pneumatic dispensers for dispensing micro dots of adhesives for years until I found this air free dispensing system. They offer several different types of dispensing systems for exact glue assembly. We are testing the benchtop system and will let you know.
This is what they say on their web site:
Control and monitoring of a consistent repeatable assembly fluid deposit worldwide resulting in increased bottom line profits through higher productivity, fewer rejects, less fluid waste and lower production costs.
