General Mach Discussion / Re: Run From Here: strange Z axis plunge to zero ruining jobs!

Thanks for your help. I use Cut2D and zero my work z-axis at the surface of the material. So cuts plunge in the negative. I attached my machine config from the manufacturer (Zenbot 24 x 24 machine).

Thanks for your help. The machine does not respond to Mach3 at all. I have to restart Mach3 program. There are no error /pins red just the "pwm bumped to minimum setting" message. Another thing I have not solved: I have finally figured out how to re-zero the machine though with saving the fixure and re-homing the machine after restarting Mach3. However, I am always restarting the job from the start instead of "run from here" because Mach3 DESTROYS the work because it always moves the Z-axis first in the "preliminary move" which is just so retarded. Why Mach3 does not move x and y first and then Z last *ALWAYS* is baffling.

Why does Mach3 EVER plunge the z axis first for a preliminary move? It should just move x and y first. I have ruined a bunch of jobs and broken expensive bits for carbon fiber trying to restart with "run from here" with this same problem. I've even moved the spindle manually above this spot but it still plunges and tweaks the job. Can you please point me to some tutorial on how to setup Mach 3 to never move Z axis first in a preliminary move?

Is there just a simple way to disable spindle control in Mach3 or the machine's XML file Would that prevent this from happening even if the gcode (I generate from Cut2D) calls out the speed defined by the tool (in Cut2D)?

I have this exact same problem with my Zenbot. It will happen randomly in a job - unpredictable. Although restarting Mach3 will does reset everything - this is NO SOLUTION! Because you have to re-zero the job / bit! I too have a spindle which is just manually controlled. Is there a setting I need to change to prevent this?
