Every time I upload a simple file from MasterCam X5 , I try to run the
program and keep getting a 211 alarm code which is

CNC Description: STORED STROKE LIMIT FIRST AREA X.
Yasnac alarm: 211 - S-OT1 (X)

I was away from the machine for two months because I got in a car accident and as soon as I came back this was happening.

Any code that has a positive value automatically over travels my machine.
the person I bought the machine from had code on there and I tested it out
and it worked fine including mine before the accident but now the machine only cuts if it goes in the negative direction. I already checked the parameters and there all fine.

Any ideas????
