Hello there. I just want to say this community has already been a great help to me learning my way around g-codes and the Haas control, and I hope you can help me now!

Anyway, I'm running a proven program to create a simple square pocket with a circular island. However, now the Hass Mini-Mill I'm using is milling a plain square pocket without an island at all. The finish pass at each z-depth follows the contour I want, but it already milled away what would have been the island. (Edit: The toolpath goes back and forth across the whole width of the pocket, just as if I were doing a plain one. It's not until the finishing pass that it follows the island's geometry...) This is extremely frustrating since I'm holding the correct finished part in my hand! So far it appears my cutter comp and geometry are still good, so I think it's either something in the G150 line or a machine setting. My instructor and another student looked at my code and we still couldn't figure it out. The code is as follows:

G54 G90 G20 G28

Note: The copy of my code that ran on the machine was erased, leaving copies on my computer and usb drive. I believe this code is exactly the same as what worked, but there is a chance I have an older, incorrect version.
