Invalid character in EIA block

[Rob Davis]

I am 7 sheets into a job and I jsut got this error message. It is in the middle of a tool change and the head is straight up from the last operation and is calling for tool change. But I am DOWN right now and cannot clear this error. I looked at the forum and it said it was a non-closed comment but it is in the tool change procedure, 7 sheets into the run???
I am afraid something is going on. I need some help.
Tried calling T-Wood but nobody home at 4:15??

The message has now changed to "the plc program in the control did not respond to the tool change request!!! Push E-stop, then NC-reset twice and home machine. If that does not help, contac tThermwood Tech Services."
Here goes nothing!

Back running again after home machine and then jump ahead to sheet 7 and recutting that sheet. On sheet 8 now and running OK. Any ideas why this happened?

Sometimes when an error occurs during a tool change a line of code is inserted into the program that has to be deleted, I think its purpose is to make you check and make sure the right tool is in the head. At least that happens to me sometimes, I'm using thm v7 and the latest control nesting.

I always reload the program from were it was written .

I get the same error some times I have found out that it is best to re wright the Cnc and start back on the sheet that the error happened on. On some occasions these errors might corrupt the code and continue to error Until the code is re written.
