We have bought a Heiz 3-axis milling machine with a 'roundino' stepper-driven rotary table and are using EMC2/Axis version 2.2.5 installed from the Ubuntu live CD. I have it configured based on the step_mm examples and have the 4 axes calibrated and working seemingly OK.
I notice that the rotary table can be commanded with 'g1 a(xxxx)' to set it spinning and if I set F300 or F500 then it's rotational speed is adjusted accordingly (I don't know what F(xxx) means to a rotary table as it is not linear - can anyone enlighten me?). G0a(xxx) turns at the - somewhat faster - jog speed. If I issue a 'F300' then 'G1 x15 a3600' (Cut a spiral 15mm major radius and 10 turns) then the rotary table turns at what I estimate as jog speed. In fact the setting of the F parameter does not seem to influence it at all when the motion is combined with X,Y or Z movement, although it does when only rotary motion is programmed. This seems to me to incorrect operation, but it is also possible that I have misunderstood something. Can anyone tell me if I am driving the machine wrongly or is there a bug in EMC/Axis here?
