Meldas 4 axis post

Hi I am trying to configure a Meldas post to accept a 4th axis I have got to a issue which I cannot get past. I have followed the instructions from Autodesk but the post keeps failing with the error below.

Error: REWIND: Rewind of machine is required for simultaneous multi-axis toolpath and has been disabled.

As this is my 1st attempt at post manipulation I am struggling to get past this. HELP!!

Hi @pgoodson

The attached image shows the error for rewind, this is happening due to rotary limits mentioned in the post is reached so it tries to retract to the home position. Mostly the 4 axis machines allows the cyclic motion it doesn't need to be retract and reconfigure. To rectify the error follow below method.

Change this :

var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], range:[-360, 360], preference:1}); machineConfiguration = new MachineConfiguration(aAxis);

To this :

var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], cycle:true, preference:1}); machineConfiguration = new MachineConfiguration(aAxis);

Save the file and test nc output carefully.
