Machine all of a sudden stop because a limit is hit is of course really annoying, will maybe not wreck the part but ... Could take some time and accuracy to recover from with a not to low risk of failed attempt and wrecked part beause of user error. Workaround to trigger correct recalculation seems to be. Then offsets are changed reload file or restart Linuxcnc. Then tool length are changed restart Linuxcnc. Guess the fix is to trigger the calculation whenever any offset is changed and any tool length is changed. Anybody know anything about to fix this?

It seems reload work if reloaded work for both methods if file is changed on disk. Though still only possible to use the green reload or shortcut once after a file is loaded or reloaded by other method.

Re: [Emc-users] OT Fanuc ot-c cpu power supply A16B-1212-0950
Hello again guys, Well, the situation is this: The machine always turns on with all it's functions working properly, with the exception of the screen which sometimes works and sometimes does not (when it fails sometimes there's no signal at all on the LCD monitor, and sometimes there are white lines on the screen). Voltage on the graphics board falls within the limits the manual says it should be so I'm guessing this should be a graphics card problem, but this could also be a main board problem too, no way to know. It's a real pain in the ass because the machine all works properly, but I also have all the means and components to convert it to LCNC (replacing the servo motors entirely, I don't have too much time to experiment controlling the original fanuc motors). If I replace the fanuc motors I will try to control them outside the machine with a new encoder and a generic driver for PM motors so I can re-use them. Or maybe I'll sell them on ebay with their drives and power supply and forget about fanuc equipment. Next time we purchase a machine, we'll try to find one with the control burned and convert it directly to LCNC, I don't even need to mention the advantages... Thank you guys and I hope you're all doing well!
