Hi support team,
I'm a CNC board and software manufacturer and I'm writing PP for 3, 4 and 5 axis Mill machine configurations.
All worked fine with 3 axis Mill PP and our customer are already using it with Fusion 360.
Now I'm writing 5 axis mill PP and I've got some problems with post-processed NC.
My 5 axis CNC do not have RTCP so I'm using the table-table way.
The tilt-table use A on X how Master and C on Z how slave:
Like in image A move from -90 to 90 degree and C axis can rotate to infinite negativo or positive.
Just to place the limits I've added in first lines of onOpen() a range to C or -9999 to 9999, I thought is enough.
function onOpen() { // configure for 5 axis table on table VMC (A master of C) if (true) { var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], cyclic:true, range:[-90,90], preference:0}); var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], cyclyc:true, range:[-9999,9999], preference:0}); machineConfiguration = new MachineConfiguration(aAxis, cAxis); machineConfiguration.setHomePositionX(toPreciseUnit(2.5, IN)); machineConfiguration.setHomePositionY(toPreciseUnit(2.5, IN)); setMachineConfiguration(machineConfiguration); // 0: Maintain tool tip position (TCPM). // 1: Map tool tip position. // 2: Map tool tip position for machine axes in table only. optimizeMachineAngles2(2); } if (!machineConfiguration.isMachineCoordinate(0)) { aOutput.disable(); } if (!machineConfiguration.isMachineCoordinate(1)) { bOutput.disable(); } if (!machineConfiguration.isMachineCoordinate(2)) { cOutput.disable(); }
I've added upon code how suggested in other post to enable 5 axis in CAM when user uses "Multi-Axis" features of Fusion360.
I'm using WCS how reference point (which will fall in exact axis line where A meet C in tilt table).
This is a schema that I've already used with VisualCAM & RhinoCAM.
Looking at Fusion360 path result seem fine:
But when loaded in my CNC environment is clear that path is not fine and at run the final product is wrong:
I guess to have made some big mistake enabling 5 axis in my PP.
Thank you for support !!!

Something was not good in copying / pasting the screenshots in the previous message made with Mac OS X Sierra.
Once the thread was published the images of the print were visible, today a black icon is in place.
I will try with Windows 10.
