Hi, I am currently designing a little laser cutter and so I have two stepper motors, the controller electronics (2x L297+L298 driver) and a 1W laser diode that needs 2V.
I plan on running the 0.9deg/step steppers at 24V and 0.5mA, the laser at 0.5A and 2V and the controller needs a 5V supply too, the power supply I want to use is a 24V 2.2A laptop charger. My idea is to use voltage dividers to get voltages slightly above 2v and 5v and use an LM317 and 7805. I have read that the motors being an inductive load can cause a lot of noise so i am a little confused.
I have the complete driver schematic, the 5v and 24v are separate at the moment but I will combine if its possible, you can ignore the optocoupler and transistor part as ill start a seperate thread for that unless you really want to point out any problems it has.
I would greatly appreciate any help, I need to start building this soon.
Thanks
