I see someone says 'Ahh so close' - I think I was closer!!
Successful build spread over several days, and that fearsome moment when you plug it in and hit the ON button.
So I got through all the self test and calibration and onto para 6.3.9 on page 26 of the handbook which is the kit only 'First Layer Calibration' which is the last task before Chapter 7 Printing!!
It didn't print. Where do I start to fault find please? Everything had been fine up till then though there was a requirement at one point to check the nozzle for which I couldn't find an instruction so ignored it. The printer did all the expected movements but nothing came out of the extruder - and yes I did have filament plugged in.

RE:
A couple things to check to start the troubleshooting process.
- Check to see if the extruder motor is turning. If not then check the connection to the Einsy Rambo board.
- Check the tension on the idler to make sure it is gripping the filament. If not tighten it.

Thanks so much K7ZPJ. Apart from the query as to how one checks that that motor is running ! After my posting I went back to the machine and pulled the filament back out of the entry hole and it had clearly gone down a considerable distance which makes me think that the extruder motor had pulled it in. But then I am now reading that the extruder has to be preheated (page 25).
I mentioned that there was an instruction on the LCD screen "Please clean the nozzle for calibration. Click when done", (3/4 way down page 21) but am not finding any guidance on how to do this.
In contrast to the "Assembly Instructions" which are the pinnacle of clarity (nearly always!!), the Handbook Instructions are poor and confusing.
Cheers.

Yes - well sometimes it is better to go back a step and then find something obvious. Step 36 on page 127 is quite clear that the IR filament sensor plug has two rows of pins and the lower are the important ones - missed that didn't I. Fortunately the dire burn-out warning hasn't occurred! I had my suspicions that the problem lay in this sensor area and it was reading someone else's post on a Prusa site that sent me off checking. Thanks for the help given.
