BackUsing the current 12-position rotary switches are actually 2p6t, which means only six different step counts are available until the replacement arrives - Wiring SW15 (once/stop) and cascade out is easier done via skywiring; only one cross-board wire that shouldn't be over about 20mm in diameter at the first break, the start a cycle of MS1->MS2->MS3->MS4->MS1, moving on after each break. We haven't done MS5 in a ring arrangement; a challenging PCB and/or print job! See PDF at https://raw.githubusercontent.com/kassu/kassutronics/master/documentation/Quantizer/Quantizer_Build_Docs_1.1A.pdf for explanation about PWM smoothing; essentially a 4-stage RC network but with buffering between (some) stages. Needs a _big_ knob, these are some setup variables... You probably won't need to mess with them. Negative_knob_radius = knob_radius_bottom*-1; // this is the cheaper option but won't reproduce tiny smooth curves all that well. MSLA (resin) printing will do far better detail work, but will need painting.
