Touch plate error

if the command takes lmore then 5 seconds to finish - that will cause an error... not sure why it would be the parameter missing error though.

Does that sound like it might be the problem?

Myscion, I tried hard coding the search velocity with various values and the error message always displays. When displaying the code in message windows it all appears correct. Interestingly the routine has been updating the offset table and positioning the machine correctly so really it's mostly just an annoyance. So if the function is working correctly then what? Maybe it's not exiting the function clean and throwing the error? Not sure.

thanks

Cmorley, I tried speeding up the search and home velocities to test but still the same error message. Good idea to test.

thanks

So I am looking at master, around line 905 and it is different from what you quoted.
So either your master branch is old or you are not using linuxcnc's version or you modified something.
Can you paste the code snip it

Here is the code, it is from qtdragon_handler.py. master unmodified.

thanks
