Agree with you, Mike, Aussilek's HCL be prickly, bit of Mr Dundee. Has a menthal bowie.
Now I have the (questionable) honour to present another, not so elucidative fact we have missed somewhat:the syringe-to-target distance. The issued approx. 50um goes sometimes down to <10um or even hits, caused by substrate warpage. In these positions, wet chemistry "bleeeds" out, but flakes, too large for the little space left, can't leave needle exit, and...you get at haemorroid. The countermeasure was to tell the machine to check space repetedly  and make the necessary needle height correction. Lesson: keep right distance.

Aussilek, how on earth did you get the cotton through? Did you run a full spool?

Hang about. I'm not in a competition here to provide the perfect answer, If I could
do that based on a couple of postings I would be beyond even the Werner class.
Suggestions made are to help provide information which will help find a solution. So
you can either try and describe the internal shape of a dispense needle using words
or say take a look at those supplied by.. The intention is to increase the knowledge
base at the other end. I know the standard EFD syringes are a bit wibbly woobbly for
precision automated high speed dispensing, but they have knowledge in this area and
probably can add 2cents and a couple of other contacts and so on.
If you want a pumpkin wine recipe you can have it, but I didn't want to clutter the
whole of technet with it.
