This Dura is a 2007 model. I haven't tried G20 since we first got it going, so don't recall exactly what the issues were, but remember being very startled when all the offsets were suddenly wrong when G20 was called. Solution was instant and total metrification for cnc machining in my lab :-). Since few of my students have any significant prior experience machining, they don't generally grumble about giving up "thou's".
The other Fanuc quirk that catches them is forgetting decimal points on whole numbers. X10 is 10microns not 10mm, while X10.0 is 10mm. It's turned a few parts into big spiral chips on the finishing pass. -- Ralph ________________________________________ From: Feral Engineer [theferalengin...@gmail.com] Sent: Friday, July 16, 2021 11:55 AM To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] OT Fanuc! CAUTION: This email originated from outside the Walla Walla University email system. On the dura, is the issue that it just moves the decimal instead of converting the values? That's just a parameter change. I don't recall the dura using tc controls, i thought those started with td? I may be wrong, it's been a while since i saw one of those in the wild. Phil T.
