Auto home nothing happens (no repsonse)

Vertex 3D Printer Vertex - Assembly and user manual

Hi,

I have successfully uploaded the new (ONE head) firmware and stored it (as per the instructions). Then removed the programming shunt.

When I access the menu and go to “Control printer” submenu and then select “Auto home” nothing happens. No sound, no movement, nothing…
The LCS display just returns to the “Auto home” option. Pressing it again does not work.

When I look at the motherboard I see that to red leds are burning LD9 (close to a driver board) and LD3 (close to FAN2 connector).
Also the leds at the end stops burn red (3x).

What can I do?

Is the printer connected only via USB?

Yes, I have the printer connected with the computer by USB.

No SD card or what so ever…

I think Velleman is trying to ask if power is connected?

My mistake, also the power (220V) is connected. :slight_smile:

I changed the stepper motor drivers (swapped places) and now only the “Z-axis” is moving.

I think one (or more) of my stepper motor driver is defective.

See also my other topic “LCD display fades out” as they are probably related.
