QTPlasmaC float switch activated during JOG

Hi, may be you can help me, when we are pisitioning the Z axis clos to the material,  some times by error it hit the material and the float switch is activated, machine stop wich is good, but then i can't get out of this situation and i have to turn the machine off and manually turn the z axis.

when this happens, jogs are inhibited (to prevent damage to the torch, material, etc.). You have two choices:

1. Go to the settings tab and check the radio box "Override Jog". The behavior of this radio button is described in the user manual in this section (its toward the bottom of the table): linuxcnc.org/docs/devel/html/plasma/qtpl...#plasma:settings-tab
2. change your preferences file to always allow Z+ jogging when Jogging is inhibited. This will allow you to press Page Up and get off the material and restore normal jogging. Here is the user manual on that topic: linuxcnc.org/docs/devel/html/plasma/qtpl...og_inhibit_via_z_jog
