I have rich experience with precision mechanics using stepper motors driven through specific drivers and MCUs like AVR and C2000 (dedicated for motor control). How can you drive 7 stepper from AVR ? Do you have at least 7 dedicated timers/counters with compare units for that or do you use signal multiplexing. Current regulation of stepper motor is accomplished by ref. voltage through the driver chip. What do you measures with galvos ? heir arrow is moving according to current through the coil, so you need "something" to current converter. U-V converter is done on OpAmp easily. Could you clarify with you analog stuff on the board, as it's not clear from your description. What do these galvos show ? What do the gigipots sets ?
