how to stop and re-start a job.

[Tlempicke]

I have been attending to other chores on the router and it has brought up a question I have had for some time.

If I want to stop a job and restart I can use tool check.

But how do I stop a job, shut down the computer, restart the computer and pick up where I left off?

If you have accurate homing (index pulse like ZRI and not just home switches), then just write down the line number where you stopped the program. You can then shut off the machine.

When ready to restart, hit F4 Run, F2 Search, and then enter the recorded line number. All documented in the manual starting with section 6.3.

If you do not have accurate homing, then you will have to find some feature on your part to indicate on and reset your WCS before you can resume the job as above.

For most DIY & sub $35k commercial routers cutting wood, I would add a +1 and the following to Tom's comments:

1) Ignore the part about the index pulse (ZRI) homing. Wood moves ~.006-.015" during cutting, prox sensors offer all the accuracy and repeatability that the table and material are capable of.
2) Simply don't shut of the machine and you won't have to worry about rehoming inaccuracies.
3) Assuming this was a long cutting 3D relief model, there will likely be some wood movement due to stress relief from cutting and your z height relative to the new material height will be off. Restart, check for Z variance. If needed, pause and use the "G52 Z -#" command (multiple times, if needed) to dial in the Z height.
