Power supply 24V
The G1 uses an industrial switching power supply to convert mains AC voltage to the 24V DC used by the stepper motors, fans and control boards. The heater bands and the bed heater run on mains, not on this supply.
Specifications
Section titled “Specifications”| Parameter | Value |
|---|---|
| Output voltage | 24V DC |
| Minimum output current | 40A |
| Input voltage | 220–240V AC (EU standard) |
| Type | Industrial switching PSU (generic) |
Location
Section titled “Location”Inside the power box — the mains enclosure under the panel box, front left. The PSU is a metal box with screw terminals. It is not in the panel box behind the display.
How power supply failure shows up
Section titled “How power supply failure shows up”PSU has failed
Section titled “PSU has failed”Symptoms:
- The printer does not turn on at all — the screen stays black (if the PSU is dead, nothing powers up)
- Machine powers on but nothing moves (no voltage on 24V rail)
- Voltmeter reads 0V or < 20V between 24V+ and GND terminals
Fix: replace the PSU with an equivalent 24V / 40A+ industrial switching PSU. Contact Ginger Additive support for the correct replacement part.
Total power requirements
Section titled “Total power requirements”The G1 draws significant power — plan circuits accordingly:
| Load | Consumption |
|---|---|
| Printer electronics + steppers | ~1 kW |
| Bed heater | ~2 kW — see Bed heater |
| Vacuum | ~1 kW |
| Total peak | 2 × 2 kW, over two circuits |
US / North America installation
Section titled “US / North America installation”The G1 requires 220–240 V on two 16 A circuits (2 × 2 kW peak). Standard US outlets (120V / 15–20A) are insufficient — they provide at most 2.4 kW at 120V/20A, which cannot sustain the bed heater under load.
Required in the US: a split-phase 240V outlet — the same type used by electric ovens, clothes dryers, and dishwashers. This outlet accepts a NEMA 6-20, NEMA 6-30, or similar 240V plug depending on the configuration shipped.
Finding a split-phase outlet:
- Check the kitchen, laundry room, or garage — these almost always have 240V circuits
- If none is available in the installation space, an electrician must install two 240 V circuits, one for each mains input of the power box
Power summary for US installations:
| Parameter | Required | Standard US 120V |
|---|---|---|
| Voltage | 220–240V | 120V |
| Current | 2 × 16 A | 15–20A |
| Power | 2 × 2 kW | ~1.8–2.4 kW |
Safety
Section titled “Safety”- Always power off the machine before opening the electronics box
- The PSU capacitors can hold charge for several seconds after power-off — wait before touching terminals
- The 24V rail itself is safe to touch, but the AC input side (mains voltage) is dangerous — do not touch while live
