It is a limit of 9, and really is inherent to G-code, which has A, B, C, U, V, W, X, Y, Z as command words to move an axis. There are not many (if any) letters of the alphabet unused, and the fact that G-code ignores spaces means that this is not an easy limitation to overcome. There is no inherent reason why this limitation of degrees of freedom has to mean a limitation in the number of joints, and this is being worked on, as Alex has already mentioned. There is no limit to the number of Stepgens or PIDs that you can have in HAL, so if you are happy to control joint positions from analogue output commands or custom M-codes in the G-code you can fiddle it that way (though such moves will not be coordinated with the 9 built-in axes) -- atp ------------------------------------------------------------------------------ Beautiful is writing same markup.
