In this video session i’ll present some topics about the solder dispenser. I run in my first test in some issues, here i presents new Features, Issues and there solutions.

lookin’ good! question… I don’t want to distract you, but did you see this solder paste dispenser project that people were discussing recently? It is manual, so not exactly what you are doing… but interesting anyway. http://letsmakerobots.com/content/solder-paste-dispenser
Yes i checked this, but i decide to make my Dispenser with a real nema 14 Stepper. But yes, its also a good solution 
Yeah, i think the stepper is definitely the way to go. Does the glass tube need to be adjustable to let you adjust the height of the dispenser? Or, are you assuming that it will be lower than any milling bit and the user will re-zero the machine for solder dispensing?
I think it’s better to adjust the height of the spindle. The cannula are around 0.5mm over the pcb. After the isolation milling we can remove the endmill, but I try to find a automatic solution
