3d printer 24v power fisibility?

Projects General Guidance
1

ordered parts for 3d printer based 24v supply but I wonder is it possible to work without electrical overdrive for each component.
I think the 12v power option more commonly use in 3d printer and this is first make so I worried about that power option. so any advice would be grateful :slight_smile:

  • power supply / out 24v 500W 20.8A
  • mother board / makebase tinybee
    : power input dc12~24v <20A
  • included motor driver / MKS TMC2209
    : default? current 1.25A, max 2.5A
    logic? V 3.3V/5V, input V 5.5V-28V
    microstep upto 1/256
    dir/step, uart mode
  • stepper motor / 3pc axial drive
    : 42Ncm 1.7A 2phase
  • stepper motor / 1pc filament drive
    : rated v 9.6v rated current 0.3A/phase, 2phase
  • heated bed / mk3 214x214 3rd option
    : 12or24v
  • hotend extruder part / 24v remote distance? 0.4 option

What would that be? Never heard that terminology before.

If You post the schematics of all that stuff connected Your post would make sense and a lot more worth to looking into.

Why? 24 volt makes the steppers perform a lot better.

It might work and it might not. Is that just for the extruder? (I see 9.6V motors.)

Power (wattage) is a function of voltage squared so for example if you've got a 24V 100W heater but you're running at 12V you're only getting 25W of heat.

...The "basic" power calculation is Power = Voltage x Current and if you know Ohm's Law you know that current is proportional to voltage (with constant resistance) so cutting voltage in half cuts the current in half, and there you go.

yes the 9.6v stepper motor for extruder part that feeds filament only.
I've try to find having smaller torque one in nema serise so I choosed that. but I think it could be something worng with input voltage.
someone says motor runs faster on higher voltage but it could be hotter than lower voltage in a long time use.

electircla overdrive :blush:

schematics? ok I'll try that
