Seems the PIDs are connected to an extruder in an unfortunate way, maybe better to use the bed? Negative P should do it?\r\n\r\nI am also into the \"new board\" idea, in fact yesterday I engraved a double-sided pcb with the diode laser, etched and put solder mask on a rather large board. Experimental at this point. Will order professional quality when all is good. Main reasons are to fit a usable display http://www.ebay.com/itm/7-inch-TFT-LCD-module-800x480-SSD1963-w-touchpad-PWM-arduino-AVR-STM32-ARM-/121715736935?hash=item1c56d2c167:g:QRkAAMXQVERS66u3 and to drive seven stepper motors - X, 2 Y and 4 bed. One more disadvantage with Due is that it can only drive a few mA per pin, so in e.g. RAMPS_FD schematics there are buffers everywhere, even to drive a led is done via a MOSFET.\r\n\r\nI checked LaserWeb, haven't used that one but seems incredibly nice. Maybe it can also generate G7 raster code at some point, that would be awesome.\r\n"}}
