when you boot mach4, the value? in the increment field in the jog window does not necessarily have anything to do with what the selected step really is. running it up or down usually gets it right but on at least one occasion it didn't, had to reboot. also the move does not necessarily match the displayed increment exactly but it might be that it is in continuous mode even though it says incremental? i did not pay enough attention to this which only happened a couple of times to really know what was going on. i am sure about the increment not matching at startup.
i mentioned this in a previous email but i have now proven that with mach4 and ESS there are moves that are combined when they are very separate events and i even tried faking it with dwells and with redundant moves. it seems that ESS is being too smart about efficiency of motion and smoothness. something is also creating the exact opposite effect. if i do the moves separately all is fine. if mach4/ESS does combine the move it not only does this when it shouldn't but it makes the motion choppy. i need to check but i am sure i have the same max speeds and accelerations and have tried the moves as G0 and G1? i thought something was wrong with my machine because i listen very carefully to all the noise (through hearing protection) and flinch and am ready to hit estop is something sounds a little different (not in a good way, it sounds sort of like grinding and nothing is grinding, i know that for a fact). i know for an absolute fact that the noise of moving x and y separately is quieter than doing both at the same time.
