Subject: Re: More on - Produce Quick & Cheap PCBs with a CNC paper cutter

AFAIK  gcode is programming code for CAD/CAM software to routing holes in the drilling process

Wondered if  bundle software come with  X/Y axis easy design , this is vector-graphics enabled
rather than "bitmapped" (points instead of lines)

At first glance it would be an asset if an average user shouldn't be involved with learning gcode
programming  if the cutter comes with a visual oriented interface

So design can be transparent to the
user even without knowing the intricacies  of CAD/CAM software.

Comments about Silhouette Studio software are welcome specially from those already using it.

btw, I have seen only the so called CriCut that seems having similar concept to  Silhouette Cameo.

How they can be compared ?

Are these paper cutters suitable for an average electronic hobbyist/diyer trying to do their own PCBs  at home with only a cutter with X/Y blades and a Dremel flexible shaft ?


TIA

I would guess that there's a lot of runout on this, which does limit
the minimum trace width. One thing I might try when my Sillhoute
comes in is to use a laser to remove paint resist. You should also
use some sort of vacuum system to suck up the fiberglass dust.

If the machine is mechanically adequate for pcb milling,

the next  step would be to convert it to use gcode like a standard cnc.


This  should be relatively easy for someone "skilled in the art".
