HAAS EC-1600ZT Horizontal rotary B-axis moves: No minus sign on B axis moves when it changes directions

[JCDFCM]

 I can't get Mastercam to output a minus sign on B axis moves when it changes directions on a HAAS EC-1600ZT Horizontal. I researched the forum and did not find anything conclusive. I was informed HAAS machines need the minus sign for direction. I'm on Mastercam 2019. The WCS plane is TOP and the Tool/Construction Planes are FRONT and the operation is a multi-axis flow with the tool orientation set to 4-axis for output format and Z-axis for Rotary-axis. It seemed like this challenge has been around for sometime in the earlier versions but is there a fix in either 2018/2019/ or 2020? Any suggestions?

Thanks, JCDFCM

fixed.  In the machine definition file, under B-axis -Continuous type, select the Signed continuous. Previously I had it set to Shortest direction. The post then output negative and positive values for the B-axis to determine direction. We tested a few op types like multi-axis drilling as well as multi-axis flow and all went well.
