Haas G150 milling away my island!
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! :mad: 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
M06 T2 G43 H02 (0.25 DRILL)

G83 G99 Z-0.25 Q0.02 R0.1 F14.

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.
