CNC solder paster dispenser - how do I approach this.

[JAZZCNC]

rinse repeat.....so I don't see how I can link the solder paste dispense to a z move, else the paste would be dispensed as the z plane is descending.

This is easy with a brain just tell it to watch Z Axis DRO and while ever equal to 0.2 then turn on dispenser.! . . could easily be done with a VBscript as well using something like a While-wend loop.

Not sure I'm understanding you point about the smd components and the reel...I'm not doing pick & place, I just want to get a dab of paste at the centre of each smd pad.

Ok didn't realise that.! . . . If theres something to probe against then It's very easy to find the centre of a square or circle.
