About to Print first Part then Boom!

[aaronsinclair]

I got all the way through calibration and was on page 229-230 of the manual. At this point I began to feed the ABS into my machine and prepare for priming. Thern out of nowhere, my machines LCD turned off? The power supply is still on, because I can hear the fan running behind the rambo board. Any ideas on what is happening? I tried turning everything off and unplugging for a bit, then restarting. Nothing though. The screen does not come on? This is frustrating cause I was about to print the first part!

Some things to check (I'm assuming you're using Repetier firmware/host to drive a Rostock Max):

- When you plug the USB cable into your laptop, can you see the USB device?

- Can Repetier-Host talk via USB to the RAMBo?

- Can you use Repetier-Host to move the tower motors via USB?

Check the small fuses on the Rambo board. One of them may be blown.

RAMBo has 3 replaceable fuses. The small white fuse holders are Little Fuse OMNI-BLOCK fuse holders. They are compatible with NANO2 Fuses. Fast or very fast acting are recommended.
An example part number for replacement fuses is 0448005.MR
F2 supplies the motors and on-board power supply.
F3 supplies the extruder heater and fan outputs.
F4 is a 15A ATO (the type found in many automotives). F4 supplies the heated bed output.
Sources for replacement 5A fuses for F2 and F3 are below.
