I have assembled the Vertex Nano and it does not turn on (more details below). Instead, both fans “pulse” (start and stop in short succession). The display remains dark. On the mainboard, near the printhead connector, I see a red led flashing.
- powering via USB turns on the printer, including the display, and I am able to select various menu items
- immediately after assembly, I was able to turn on the printer once (didn’t get as far as calibration yet) but now it is consistently not working showing the symptoms above.
Any idea for further diagnostics?
Many thanks for your support!
