I'm glad to see that preheating the board is working for others. So maybe a heating element under
the board to minimize heat lose before printing? My infeed table is aluminum so I could heat it
fairly easy. I had problems with the Epson ink coming off in the etch until I made sure the board
was VERY clean. If I cleaned the ink off the board before etching you could see where the ink
actually made the copper cleaner in the trace areas. Unless the Epson ink does a better job I will
get away form it as it's too much moola. So keep it up with the MSI testing.
