PRs welcome. I think this is good practice, but ho-dang what a mess a3d4f2b82e romps with traces, vias, and net links Add four more switches/buttons, move LED drivers onto PCB Latest commits for file Images/PXL_20210831_000949090.jpg 2cb8e5eaf6 Go to file 46614f2341 Add 55k-ish resistor to coarse knob to fix - Single-step button (SW13) isn't producing a high enough voltage to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a diode to U2-3 Clock In - U1-13 (can get at from top when assembled - Stop Switch - 10 - center_adjust; // build up seven rows; middle one unused row_7 = row_6 + vertical_space/7.
