tangential axis unexpectedly dive into material.

[girogiri]

Hello All,

one more issue with tangential blade: on a three headed machine ( router + 2 tangential blades) we need to change the UCCNC configuration during Gcode execution.
This is accomplished via the M6 macro that stops the Gcode execution, change the tangential axis parameter, save and then restart Gcode execution.
If at this point we change manually the feedrate of the machine, at the successive pull out/pulldown the blade dives downn into the material and onto the machine bed snapping the blade.

any suggestion?

thanks
Giorgio
