We are now the Courtly Arts Performers (of Victoria) and can be found at https://www.courtlyarts.com/.

I put together the new site with the help of daughter Kat – and those with any interest can now acquire music, book events, see the pretty pictures and catch up on news of coming performances. The group has done its first season of concerts – with a level of attendance that I think surprised (and pleased) us all. We have also had a large number of attendees at an introduction to dance course, held last month. So the future is looking bright indeed for an infusion of new blood…

I have however always thought that a utility that regularly sent an auto-nozzle check would largely eliminate this problem – of course at the expense of some ink usage. “Just the job for an arduino project” thought I and started capturing IP packets to analyse the dialogues going on during maintenance and cleaning operations. At this point my son pointed out that I already had a NAS on the network that could run scripts to do this task – and took over the challenge of parsing the command data and writing the necessary scripts.

With amazing celerity, he has done in a few days what I probably would have only ground out over weeks. He has developed a python script that run under the (in this case Synology) NAS and which provides for auto-checks of the nozzles and reporting any blocks – and in addition from the unix command line allows for cleaning or power cleaning individual nozzle sets.

With the addition of some some further NAS scripts, my own system now runs the auto-check on a regular basis and emails me the results. If things are not OK it tells me so and I can SSH into the NAS from wherever I am in the world and invoke some cleaning.

Now, I have no doubt opinions will vary as to whether this is the optimal approach for maintaining clean nozzles. The guys who maintain my printer believe that as long as the head caps are in good condition, the printer should actually handle longish idle periods without problem. And my experience suggests that he is right; I do get blockages but nothing major / fatal. And it’s clear that this approach requires the printer remain powered up and it will use ink; both costs (which are however irrelevant to me). But at least this provides a previously unavailable option and I will be testing it in the coming year and see how it goes.

For those interested:

1. This is NOT FOR YOU unless you
   a) have a NAS that can or is running python and know your way around unix or
   b) want to (and know how to) implement this on a unix server / raspberry pi etc
2. The python script generated by genius offspring #1 is available at github
3. You will have to sort out your own mail reporting scripts depending on your own NAS. If you have a Synology NAS with DSM 5.x I can post the generic materials required to set that up
4. A reminder that you will have to go into maintenance mode with the printer and disable the auto power off timer.
5. We suspect this should work for all Epson x900 large format printers – but it has only been tested on an Epson 4900.
6. Imagine every possible caveat to using and applying this – and consider they apply. You are entirely on your own here, there is no help desk, advice, warranty of performance, survival of your printer or any other technology near it, or implied happy ending.

That said, it’s running happily on our network, “bumping” the printer a couple of times a week and letting me know the results. Because it’s driven by the NAS which is always running anyway, it is independent of whether any other machines are active on the network – and it does not rely on difficult to maintain “homebrew” hardware kit. “Bonza Mate!” – as we say down here…

Or you can buy the physical versions online from Blurb; they are quite beautiful in large format hard cover – albeit not cheap. [I make no markup – you just pay the basic Blurb price]

The new site template also does a fine job of holding any blog posts too, making my old blog site now redundant as the target for new photography related materials. However, it still has lots of fine stuff and will continue to accumulate technology posts, so I will leave it live and you can still see it here.
