Hi,
For some reason on the config that I did install, the values for the step increments for the THC, the travel height, pierce height and switch travel does not seem to always take effect immediately after I have changed them. For example, at first when I adjusted the switch travel it did work somewhat, but usually when I did change it, it had no effect on the movement of the torch after the plate was sensed.
With the step increments I slowly increased the value once because the torch was not moving up fast enough, I then change the value to something ridiculous like 2 mm and the effect seem to have took place but when I changed it back to a much smaller value, the torch still moved as if the value was 2. It was only fixed once I restarted LinuxCNC.
I did however 'fix' the problem by changing the default values to the values that I desired, and that works perfectly now.
Regards
