Making changes to the eggbot extension to take advantage of a home command might be within my capabilities – worth giving it a try – the difficult part for me is to wrap my head around the OOP (Object Oriented Programming) part ;-)
Where did you find the hub4hub serial splitter? I have used Eterlogic virtual port software to do this – unfortunately the 64bit version has to be bought, the 32bit version is free but will not install on a 64bit OS – the price for the 64 bit version is very reasonable – might go ahead and buy it.
Interesting how the QB command return got ‘jumbled’ – I am curious what is causing this just ‘every now and then’. Nevertheless – I am impressed by you coding!
