Re: resetting X 0
A quick tip: Your X Zero Set is recorded on the Management Data Card in the electrical cabinet of the machine. If it is there,(a lot of people think they are helping when the remove it for safe keeping) enter the number and verify that the PR Zero Offset number for X is the same as well.
If you are off slightly, use Broby's procedure to correct the X zero point and use the PR Zero Offset number to shift the encoder position. That way all your Stroke End limits, Zero Points, Variable limits all stay the same.That is what you want if you've entered any zero points into a program.
Best regards,
Experience is what you get just after you needed it.
