Greetings. As someone completely new to 3d printing and forums here goes. I'm the proud owner of RS Ormerod number 425. Reading through this forum I see several mentions of no 5volt supply except through the usb. I am suffering this issue. I placed the jumper on jp9 but this makes no difference and since my unit is out of the 1 - 220 range mentioned I believe it should receive 5 volts via the atxby ejg - Ormerod
