That's a fantastic idea, microetching the surface....



Dust is a problem for me too.

Strangely at first the MISPRO was great, i left it in the printer over  
several weeks with the cleaning pump totally disabled and it would still  
print without fault after weeks of standing still. This went on for a few  
months with no problems, but now suddenly it is not printing on all  
nozzles, and resists cleaning so far.
