change footprints of transistors to save on panel wires More traces and vias, and this is a corner // is placed on the larger board underneath the smaller board. // margins from edges h_margin = hole_dist_side + thickness; output_column = width_mm - thickness; // column from edge plus hole radius Latest commits for file Images/PXL_20210831_000922493.jpg 4579d541a8 Adding SynthMages footprint library How to use 7.5mm holes, not 6mm alpha pots - 9.8mm, +2mm rotary - 11.5mm, +3.5mm -- biggest by far, maybe 12.6mm? SR2511 series are 11.43? Maybe more?
