Really depends on the driver, as it will follow a set of HPGL pen moves in order. Could be the generator simply moving through the print file and getting the characters out of a font table or line list in sequence, or some algorithm that does it as the code spaghetti came from the output file. |

I gave away an A1 flat bed pen potter years ago. Apart from the possibility of using special inks like plotting resist directly on PCB material inkjets made them obsolete years ago. |

Anybody in EEVbog land using a plotter for PCB etch resist artwork? Any homebrew solutions? What pens that can be acquired these days are used? Any problems interfacing with DXP? |

Me too, the Sharpie Industrial versions seems to have the "right" ink. Just scouring the forums collective wisdom as to going down the plotter path. Been using toner transfer for years (though not a large number) and lately with quite reasonable results (SOT23/6 with tracks to middle pins from each side). But always thinking how it might be easier though. The etching is the easy and fast bit. |
