Problem with manual moving in emc2

[ad_Wolf]

Hi, guys!
How do I solve the problem: when I run through the interface axis G-code file, and then put to a pause, disconnected manual control machine. I wish that it would stay on. For example, I want to move to 1-2 millimeter tool, and continue run the G-code.

I don't understand what you are asking. What do you mean "disconnected manual control machine"?

Are you talking about changing tools and then continuing?

Please sorry for my bad English.
I mean that when I put EMC2 to PAUSE, i can not move machine manually. But I need it. Please help me!

That is because when the machine (controller) is turned on it exerts holding force with the motors to avoid losing position. If you turn off the controller, you can move the machine manually, however, EMC2 will no longer know where the machine is. This can result in very bad things happening.

Can you jog the machine while in the middle of a prorgram? If not, the next best way is to just program in a tool change.

I think he means he wants to jog the machine while a g-code program is paused...

You can't do this.

If you need set tool lengths you need to either setup a switch that uses 'probing' to set tool length - or you split the program where the tool change occurs. (so you run the first program - switch tools/set tool length - run second program.)

here is an example of a gcode program using tool length probing.

Samco,

You might be right but I wasn't sure what he meant by "manually" so I answered based on my guess. I was hoping you or someone else would jump in because I am pretty sure that tool lengths are really the key to solving his problem, not just moving to a different location.
