Z axis probe height init

You could set it so it just clears the 50mm tube.

PlasmaC is pretty good at high speed probing now so maybe you could try that as long as you have enough movement in your float switch.

Earlier you said that you made Z slower because it had some issues. You should have the JOINT_2 velocity and acceleration set to what the actual velocity and accelleration is that you reqire then set the AXIS_Z ones to twice that value.

FYI, i have probing set at 4m/m and at 150mm high on a 185mm travel, with setup speed of 9.6m/m and max speed at 12m/m.

I will check it out tomorrow.

What exactly does IHS stand for?

Initial Height Sense

Ah, I would have guessed “Search”. I work in the land of a bazillion government acronyms so I don’t assume anymore.

Then I don't understand how the IHS skip option works, because in the plasma guide there is no explanation about it. So I suggested, that if the IHS skip is active, it shouldn't search metal sheet and assume that it's the same height like it was at the end of the cut(or at the beginning of the cut when thc is off) thus I shouldn’t activate float switch. But it seems, I am terribly wrong

Well not many folk must use that feature, I broke it last August...

Thanks for the report, it is fixed now.
