Re: [Homebrew_PCBs] Re: CNC drill holes and laser printer output, they do not align. Suggestions?

2010-06-21 by Slavko Kocjancic

Hello...

I'm make PCB with toner transfer quite long. It work's so well...
And I can make PCB for small QFP with 0.8 or 0.5mm grid without problems.
I didn't know that my printer has bad output at all.
But when I go to drill my board with CNC (was drilled by hand) then I 
notice that problem as all holes isn't drilled in centre.
I blame CNC (homemade) 1'st for inacurracy but came out that CNC is 
accurate but not the printer.

Then I just put commercialy made film to my printout and see difference 
easy and goes to investigate. BAD bad Bad printer. And not just one. !

Slavko.
