Do you lose position if you lose comms?

[Bob Eustace]

Bumped the computer near the end of a job and lost comms. On a bog standard Buddy does it remember the home position if you are forced to reboot the computer and dont move the Shopbot at all? Using JH after the reboot seemed to take it back to the start position.

What is the difference between JH. And MH? What is the command to use the limit switches to zero x & y?

Many thanks

JH jogs to the home postion and MH moves to the home positon. Jogging is generally faster than moving but depends on your settings.

On a standard install C3 ([C]uts menu, Home X,Y axes using prox switches) will home the xy using limit switches.

You may need to re-run the setup routine ([T]ools menu, Shopbot Setup) to get the correct offsets from where the switches are to where you want you home to be.

Not sure on the lost comms situation as I always rehome to the same point and I'm fortunate in not having had any comms issues for well over a year.

Bob...
In most cases, yes.

By definition, lost comm means that your computer has either lost communication with the controller or received an error in return. Short version: Control software does not know exact position of the tool.

Like Adrian says, Jog is a rapid motion, move is cutting speed. Both can be set independent of each other on the Console.

JH command runs the Custom99, which can be modified to your liking. In many cases, home is considered 0,0. In many cases not. In either case, the software should have all of your settings saved. But.... if you didnt use the C3 to set the X,Y zero prior to running the file, you will not be able to use it to find, or remember, an X,Y zero location that was set out in the table for an individual file.

To have a repeatable location in case a file is interupted, follow these steps:

Run C3
Using your method of move or keypad center on new location
write down X & Y positions
Then Z2 to set 0,0.

If position is lost run C3
type in J2 to the saved location
Then Z2
