Reprap heated bed generator Remix

thingiverse

IMPORTANT NOTICE: This script is not working with Processing 3, you have to use Processing 2.2.1! This is a remix of http://www.thingiverse.com/thing:29785. My modifications: generates a PCB layout similar to the MK2a heat bed which is available at http://www.reprap.org/wiki/PCB_Heatbed option to include wires for a thermistor creates an SVG file instead of an Eagle board UPDATE Sep 12, 2014: added option to define package size of SMD thermistor used; suitable SMD soldering pads will be generated in this case UPDATE Nov 14, 2014: fixed calculation of wire resistance Instructions To generate your PCB heat bed layout start your Processing 2 IDE (download from https://processing.org) and open HeatBedSVG.pde. IMPORTANT: the script is not working with Processing 3 or later, you need Processing 2.2.1! set size of the board (h, w) and heated area (heatWidth, heatHeight) set the voltage you want to run the heat bed with (voltage) play with wire width and spacing to get the resistance required for your purpose (linewidth, traceSpacing, resistorPads). If your board is not completely filled, try different values for resistorPads if you would like to have thermistor wiring included in the generated layout, set thermistor = true and modify the thermistor wire settings as you please run the sketch; you will see the calulated resistance in the Processing window, the resulting heatbed.svg is written to your sketch directory
