Have been running a TM1P for six months with few issues. The last several days I have been getting the alarm code 430 when trying to load my program. "beginning and end mark missing" and alarm 972, "FNC file not found". When I check, the percent sign is at the beginning and end of the program and everything else seems to be correct and the same as it was. What is causing the alarm??? My G code is being generated by MasterCam X4 after drawing in SW.
Any help is appreciated
