Troubleshoot Error 62 (G4 CNC with M830 motherboard only)

During bootup or after editing a program, the control drops to DOS and screen reads "Error 62 at pgm ctr ..."

The error 62 message is an indication that something went wrong while the control was trying to save the offsets. Your offsets have been lost, so you'll have to touch the tools off again, but first, you need to replace the offset file.

To Repair the offset file:

Boot the machine normally, and when you get to the Omniturn logo/file backup screen, press Ctrl-C instead of Y or N.
You'll be asked if you want to terminate the batch job. Say Y to that prompt.
You should now see the DOS prompt (K:\CNC).

At this prompt type C: then press Enter. Now you should see the C:\RUNFILES prompt.
Type edit tcmp then press Enter. The editor will start, with your tool offset file displayed.
Clear everything out of the file, and enter 32 lines that say this: 0,0

There is a line counter at the bottom of the edit screen so you can keep track of where you are in the file. Make sure your first pair of zeros is on line 1 and the last is on line 32.

Note: If you are DOS-conversant, you can download TCMPZERO, rename it TCMP and copy it to your C:\RUNFILES directory.

Once you've got the offsets zeroed, press Alt-X and save the file and exit the editor, then reboot. You'll have to touch your tools off again, since the offsets are zeroed out.

If repairing the offset file doesn't help, the next step is to restore the hard drive from the thumb drive. Instructions to do that can be found here.

If restoring the hard drive from the thumb drive doesn't help, the next step is to replace your hard drive and run off the USB stick until your new hard drive gets there. Instructions to do that can be found here.
