Hi !
I'm building a 3d printer with 24v stepper from old printers. So, I modify my ramps to run with 24v.
But I would like to use 12v for the hotend, fan and of course arduino.
I would like to know if it's possible (and safe) to use two power supply :
- a 12 atx PSU
- a 24v 7a power supply
My idea is to connect the negative of the two power supply together.
I hope someone can help me :)
