Torch doesn't go down while cutting

When running a G-code, like the uploaded example, somethimes the z-axis motion doesn’t work like it should. The torch doesn’t descend to te plate. It just moves a little on the moving height, starts the arc and makes the movement. But is doesn’t go for the pierce height.
The next move all can be normal again.

Does our Arcdroid need an update or is their a setting problem? What should I look at?

Look in tune and make sure that file is set properly. That file must be loaded and check the file cut settings in tune. If may be a conflict between your g code settings and the Arcdroid cut settings

You are probably experiencing a false probe

Not probing before every cut causing the torch height to be too far to pierce

my machine is leveled with the table i re leveled it because it was slightly off thought this was causing my issues but after fixing the table and re calibrating my machine, my first cut started off great it cut 5 pieces fine then went back to not probing and not getting an arc then a few pieces later it started working well again and probing before piercing.

Sounds like the torch cable is getting in a. I d every so often and giving you a restriction on Z axis. I had that problem when i first set up mine. Just make sure it is supported good and has a loop so there is no bind.
