Homebrew PCBs

I have, just last week.  :(

My Canon MP730 inkjet and Konica/Minolta 1350W are 'short' on distance for
SMD pads.  They were just fine for thru-hole parts, but they lack slightly
on SMD precision.  The part in question is a 30 pin FFC connector with a
pitch of 0.5mm.  The output of the 2 printers above is about 1mm short on
total length.

I have to test a HP LaserJet 2000 and LaserJet 4V; hopefully these will
prove more accurate.  If they fail as well, then I guess I had better get
that CNC-capable machine working pronto.

Objet : [Homebrew_PCBs] Artwork for CNC drilling PCBs


Hi,

Just finished putting together a CNC drilling machine and have now 
stumbled on a problem that I never anticipated....The drilling machine 
appears to be more accurate than the printer used for the PCB 
artwork....Tried both a HP2420 (laser) and Epson 2200 (Inkjet) and the 
results were similar. Is this a known issue with CNC setups?
