@ -127,21 +127,26 @@ So ALL my motors are 4-wire bipolar-series motors!
2. Power_supply_current = number_of_motors * 2/3 * motor_peak_current for "bipolar-parallel motors"
Since ALL LDO motors I own are bipolar-Series Motors we will use Rule of Thumb #1 ONLY!
Power_ _supply_current = (5 * 1/3 * 2.0 Amps) + (1 * 1/3 * 1.0A) = 3.333 + 0.333 = 3.6667 or 4 Amps in series for 48V @ 4Amp = 192 Watts or 200 Watts PSU (if the PSU supplies the full power without an aluminum plate for heat dissipation).
Power_ supply_current = (5 * 1/3 * 2.0 Amps) + (1 * 1/3 * 1.0A) = 3.333 + 0.333 = 3.6667 or 4 Amps in series for 48V @ 4Amp = 192 Watts or 200 Watts PSU (if the PSU supplies the full power without an aluminum plate for heat dissipation).
Power my Voron 2.4 48VDC 250 mm Build (running all HT motors from LDO at 48VDC) with the following:

So I could use option 3 & 4 OR 5 & 6. Since I plan on LEDS and running a Raspberry Pi 4B with a solid state disk drive via USB 3.1 interface instead of using a Micro-SD card I want to have enough power to add extras to my Voron Build.

I opted to buy the following:
