  1. Hey yall, I am attempting to update a generic Haas VF- TR post to accommodate my UMC 750. I have all the rotary axis and directions set, but I am getting this weird rapid motion between operations when the rotary repositions, instead of retracting and doing one single rotation, it seems to be attempting to track the x,y,z moves with the rotation. See the attached NC code, I've deleted a lot of the fluff to make it easier to read. I am fairly green at post editing, where do I need to be looking in the post to fix this? Thank you!

  2. I'm trying to run a few simultaneous 5 axis surfacing toolpaths on a Haas UMC but I can't get the machine to cut at the correct feedrate. I started out with an angle increment of 3 degrees but the motion was pretty jerky so I reduced it to .5 degrees then .1 degrees. The motion looks smooth now but the toolpath takes far longer to run. According to backplot the toolpaths should've taken a little under a minute and a half but at 3 degrees the actual machining took just under 6 minutes and at .5 degrees probably closer to 20 minutes. I'd imagine .1 degrees would take over an hour. I tried playing with the toolpath tolerances in mastercam as well as the machine's smoothing settings but none of that seemed to help. Is there an easy way to get a simultaneous 5 axis toolpath to cut smoothly and at the feedrate you specify? Thanks
