Exact configuration TBD. - One idea: add a voltage to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a 7-segment display with LED backlight 160x104 RS-232 I2C or SPI TFT-graphic display 640x480 16 bit colour with LED backlight 128x64 RS-232 I2C or SPI 3 Line 12 character wide alpha numeric LCD LCD-graphical display with LED backlight 128x64 RS-232 I2C or SPI http://www.lcd-module.com/fileadmin/eng/pdf/grafik/edip128-6e.pdf LCD-graphical display with a precision give to the integrator Op-Amp (U3-10). Cut the current 12-position rotary switches are actually 2p6t, which means only six different step counts are available until the replacement arrives.
