Z Axis overtravel at end of program
I just borrowed a '97 4020 CNC HS88 with software updated to a copyright date of 2002. I am new to Fadals and normally run Mitsubishi controls.
It has been running fine for a couple of weeks, but now at the end of the program, the Z Axis goes straight up and over-travels and shuts off the drives. I am using the same post (I think). The machine is in format 1. At start up I enter SETH at the CS position and I am using E1 for my fixture offset.
The code is:
N21660 G0 Z10.
N21670 M5 M9
N21680 G91 H0 Z0.
N21690 E0 X0 Y0
N21700 M2
I tried removing line 21680, but it still does it. The post is the one that came with MasterCam 9.1 SP2.
As a temporary fix, I have been adding an M00 before that line. When the program reaches the STOP, I press Manual and enter HO to send it home.
Confused!
