The only current issue is that the electronic lube pump is a lube first version. It's over lubing the mill. As soon as I hit cycle start it turns on. So, that's not good if you stop and start often. The mill is dripping with oil. I don't think I can shorten the pump time. If It did a quick shot of ...

There are many possible causes for loss of position. Mechanical slippage somewhere is most likely.

A good starting point for troubleshooting would be to restart the control; home the machine; and mark the motor shaft orientation, ballscrew orientation, and axis position with each axis sitting at ...

I suspect there is still an issue with the spindle encoder, or the spindle encoder cabling, or the EMC-PG01L board in the Delta C2000 drive.

You could test that by changing Pr. 00-11 in the Delta drive from 3 to 0, so that the drive runs the motor in an open-loop V/f mode instead of the closed-loop ...

Yes, if it were any ordinary PLC-reported fault condition, then pressing and releasing emergency stop would reset it.

If your problem were directly related to the emergency stop button, then you could replicate the problem simply by pressing and then releasing emergency stop.

In your picture of ...

You could use the PLC Detective logic analyzer to log when, and for how long, the EStopOk input was open; and whether any other inputs opened at the same time.

I came in this morning at 9AM, and it was in e-stop state. It generated a weekly report too. Restarting CNC12 didn’t fix it. I had to quit ...

When you use the F8/Graph key in CNC12 to preview the program before you try running it, you can look at the scales/rulers on the Graph screen to see where the toolpath cuts, relative to the WCS X0 Y0 Z0.

BTW, the PLC has nothing whatsoever to do with WCS locations or G code interpretation.

If you can find them in a pre-update report or in a backup of the pre-update cncm folder, and they were not corrupted back then, then it would work to restore those copies.

Reinstalling CNC12 and choosing to install a factory-supplied PLC program would give you fresh factory-standard macros, but it ...

Assuming that your 6/6/25 v5.26 report is still current, your M3 and M4 (and M7 and M8) macro files have been corrupted.

All the characters in those macro files have been replaced with zero (NUL) bytes.

That is probably why you cannot start the spindle in Auto mode at the MDI prompt (although I do ...

In general, you can keep the spindle off simply by selecting Manual spindle mode. In Manual spindle mode, M3 and M4 cannot start the spindle.

Unfortunately, the factory-supplied M3 and M4 macros prevent you from proceeding without changing back to Auto spindle mode (at which point they they start ...
