Hello fellow machinists,
I recently encountered a problem with the cnc mill I'm working on. It uses the Fanuc 0M controls and I usually runt it with a drip-feed.
The problem is that at some point last week the cutting feedrate (G01) got "stuck" at 1260mm/m, meaning whatever I set G01 F____ to it will always run it at 1260mm/m. I do not know where this came from, I was just repeating the same program I ran before without any changes. The rapid (G00) works just fine at 7500mm/m. There is a manual speed override for all feedrates, including rapid, when I turn that on it will run everything in the feedrate I set the manual dial to. But this is obviously not a solution for a program that needs multiple tools and operations. The problem occurs when using code generated with Fusion360 via the drip-feed as well as on code directely entered on the controls of the machine. Sice it does run at slower feedrates on the manual override I do not think that it is some mechanical problem with any sensors but rather some problem in the software.
Do any of you have an idea what could have caused this and how to undo it?
PS: There are no error codes shown anywhere.
Kind regards
Benedikt
