Hello,

I require possible causes for the following error codes,

Code # 100 MT232 module error
Code # 3400 single block stop when cutting

The machine generates these codes during a automatic cutting sequence.
While running in automatic the machine will switch to single block operation and
the display screen will switch to Display mode by itself.
This fault occurs at random locations during the cutting sequence but most times
at the start or the end of the cycle.
The machine sometimes also stops with a soft limit fault but the table position is ok.

I changed the WMT card 4 weeks ago and this problem went away until now.

There are also a lot of junk characters displayed on the screen just above
the function key descriptions.
