MULTAX Mode Cycle -- Most machine tools support hardware cycles (G81 etc) only in the XY-plane or in 3-axes mode as set in the cycle panel G-code section. If the machine is a 4/5-axes machine with rotary table, the GPost will rotate into XY-plane automatically for any tool axis. In this case, leave the 1st setting to "Same as 3-axes mode". If the machine has a rotary head or you want to switch to a software cycle in MULTAX/ON mode, then select the "Mixed mode" and then set the desired option for various tool axis input. If the machine tool supports hardware cycles (G81 etc) in YZ and ZX-plane cycles, this can be specified. (Intcom 4355)
