Brevity is the soul of wit, so they say. Of wisdom too.
So some tips that may help you:
I've sometimes prepared long texts in MS 'Word' (which has a word and character counter) then copied the text to the thread.
Ask yourself….
– What are you describing? The system or its every component?
– What do the photos show? Completed parts or detail machining?
– What is your aim? To suggest a lubrication system (with computer control??) in general, or to show your specific system?
– For Whom? Beginners needing step-by-step help, or reasonably experienced model-engineers?
– Would the work be better offered as a constructional series to ME or MEW – the latter perhaps more appropriate?
Really, a few carefully-chosen photos and brief notes on pipe sizes, fittings etc. should be sufficient to help others wishing to build their own version, remembering their possibly quite different machine-tools and facilities from yours. Reserve deeper detailing for the more complicated, specific things built for it, such as any pump, filter, etc.
You mention software. I am not sure where that is needed in what I take to be a machine-tool oiling system, but a programme listing might be better as an appendix, second article or offered directly by e-post.
