Like said, my programming experince is minimal, so im not sure what impact the following changes would have. But i believe this would be all that is needed to allow them to handle more axes. (least 26×6 = 156).

Like said Ive been able to get it to work for the 6 axis, across 2 board with rs485. How do we control more?
I would think that a minor code change on the tinyg could be to change the axis name that the board recognizes from X, to AX, BX, etc. The rest of the code could be left alone.
Unfortunately that is outside the scope of my programming knowledge.
OK, i misunderstood what you were saying.
Your saying i need to have 2 separate g-code senders talking to each board on a separate com connection in order to do this.
Ok…
But the board is advertised as being able to be linked with RS-485 to be able to network 1000 axes. This is what I want to do. How do i do this?
I’m wanting 1 G-code sender, to talk over 1 RS-485 line to handle 8 axis. This is what is advertised as a feature of this product. And is what i want to do. But the documentation page on the wiki about networking is blank.
