It should conventionally be "C" (A is parallel to X, B is parallel to Y, C is parallel to Z) You control which axes are enabled with COORDINATES = XYZA in the INI file. If you want to start using C then you would need to edit that to XYZC, but to also add 2 more axes and alter the HAL file to send axis.5 values to the stepper motor. I think you are probably better staying with the XYZA configuration (it means all your G-code continues to work). If you want to stop changes in A value moving the tool in the preview display then all you need to do is edit the INI file GEOMETRY setting. That probably says XYZA. Change that to just XYZ and the A movements will not be shown. I think this is only valid in EMC2 version 2.3 onwards which I think will work on 6.06, but I am not sure how you would upgrade. If you want to Show rotary axis movements correctly then I think you need to change the number of axes (AXES=6), change the HAL file to connect axis.5 to the stepper, change GEOMETRY to CXYZ, change COORDINATES to XYZC, edit all your G-code and, to avoid displaying non-valid A and B axes, also update to a newer version of EMC2. Much easier to continue using A. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
