Hello all - here I found interesting approach with lots of reality incorporated in this SmartDispenser - NO AIR !!
http://gentec-benelux.com/airfree/ 

LDS9000 et SmartDispenser

Sturdy precision machined screw and precision motor assure zero backlash during operation which eliminates any leak in the hydraulic line chance of pressure loss.
The stepper motor is directly engaged with the screw eliminating lags and backlash, and is preventing any chance of pressure loss.
Patented Precision machined Piston Stabilizer holds the piston straight in the reservoir, eliminating any chance of pressure loss.
PosiLok™ Quick Release threaded hub and piston allow zero slippage between the piston and drive rod, eliminating any chance of pressure loss.
PosiLok™ Quick Release threaded hub and piston allow zero slippage between the piston and drive rod, eliminating any chance of pressure loss.
NoFlex™ Linear Drive Technology gives you the accurate and repeatable method of positive displacement you want without the headache of pneumatic systems. There is no need to flush chambers or valves. Formulations stay untouched in safe, silicone-free barrel reservoirs with this revolutionary new system. You can change fluids or volumes with ease. Unlike AirPulse™ machines, this intelligent dispensing system knows the barrel size, volume and the dispense rate. The result: you get a process control that is unachievable with AirPulse™ systems. profitability.

SmartDispenser™ uses air-free, linear-drive dispense technology to achieve the highest repeatability when dispensing assembly fluids. This technology allows manufacturers to establish one dispense program globally, with no change to fluid deposits. By standardizing dispense programs per product, manufacturers reduce the cost of product validation. The technology also eliminates fluid waste, rework, rejects, and costly air compressors, thus maximizing
By integrating the Windows 7 platform into its technology, each SmartDispenser™ system can be networked to a desktop, laptop, smartphone, or another SmartDispenser™. This technology gives you the ability to monitor live video feeds and real time production data, and enables.

Looks expensive, how much? Would be interesting to buy just the dispenser and build a DIY controller for it.

It is for sure not in price range of my Dispenser, it comes with a magic box -controller...

BUT THE POINT IS STEPPER DRIVEN SOLDER PASTE DISPENSER WILL TAKE LEAD in dispensing - AIR REQUIREMENT IS NIGHTMARE TO ME!!

Just to clarify, as it wasn't immediately apparent to me, the unquoted text starting from "Fishman has..." was the text of the response by Fishman corp.  For a minute, I thought mike was representing Fishman products.

I came across this web page Change unipolar 28BYJ-48 to bipolar stepper motor  http://www.jangeox.be/2013/10/change-unipolar-28byj-48-to-bipolar.html
might be useful to get more power/torque out unipolar stepper ....
@Zapta: would be interesting to test your dispenser by using the same motor but with a higher torque. I guess you would need to change the driver to a bipolar driver for the motor.

The   28ybj-48     stepper motor would need to me slightly modified to be used as bipolar stepper motor - in addition there is integrated tention clutch in that motor - see video -

My understanding is that you don't even need to modify the stepper to use it as bipolar stepper. Just leave the red wire unconnected. Doesn't hurt to cut the trace though if you don't intend to use it as unipolar stepper.

Correct, but you need to change from ULN2003 to L239D driver!

Sure. That's also clearly described in both of the links (with and without cutting the trace).

Why don't you try some other gear & bi-polar stepper motor if Trying is the first step towards failure ?

I think you also need to increase the voltage, otherwise you get half the current and double the number of turns so no chance. Unless if you manage to have the two halves in parallel in the right polarity.

Yes, but does it really give significantly more torque since it uses now roughly half the current?

You can find your answer here:
http://www.jangeox.be/2013/10/change-unipolar-28byj-48-to-bipolar.html
"Finally, most importantly, my torque test resulted in :

800gcm !!

which is at least twice as much as full stepping unipolar (380gcm) and almost 3x more powerful than my half stepping unipolar test (300gcm)

Basically, if I cut one wire in the motor, it gains almost 3 times its original strength."

But that 800gcm is not with 5v :)

The torque gain comes from going from 4v (the ULN Darlington has 1v drop) to 9v.

There are several versions of this motors 5V and 12V.......  - see https://grahamwideman.wikispaces.com/Motors-+28BYJ-48+Stepper+motor+notes
Torque results
See All torques in gram-force * cm.

Most notably:
Note 1: My test for pull-out get to about 200g x 10cm, and at that point broke teeth in the gear train. See images below.
Note 2: Neither Adafruit nor RioRand [as of current writing] list a pull-in spec, a spec which is crucial for actually moving a load.
Note 3: Adafruit's spec for pull-out torque is low by a factor of six! That is, the motor is six times more powerful (in holding) than Adafruit says it is.
Note 4: Perhaps unsurprisingly, the RioRand 5V motor's pull-in torque was about 4x that of the Adafruit 5V motor, corresponding to the 4x greater step-down gearing.
Broken teeth while testing pull-out torque......

I see the thread here has taken a turn from the original question, but figured I'd share this dispenser, (Loctite brand for $35USD), I Just ordered it last week, should get it anyday:

https://www.all-spec.com/products/98815.html

Allspec also sells the Loctite needles in a variety of gauges.
