I need a breakout logic board design and schematics for the carriage (hotend), it consist of up to 3 hotends
Each hotend is acompanied of heater carthridge(2 wire), thermistor(2 wire), hotend fan(2 wire), part fan(2 wire), lift-up nozzle servo w/encoder(10 wire just for servo/encoder)or(one proximity sensor of 3 wire connection) an d sxtruder stepper motor(4-wire)
If possible I woould like to ad smd leds for each device for feedback reference of correct functioning.
Design for 2-wire screw on terminal for inputo voltage, JST-2.54 connectorts for rest. please remember that is for 3 sets of what is mentioned above.
Please advice what is smallest it can be done.
I would like to 0land with 24vdc and common ground and which would supply power to most components and have a voltage reg to 12v in case a sensor might be neded and a 5v drop down for prox sensors and optical sensors.
