Zheight

[Bruce James]

I,m running V-Carve and Mach 3 At the start of every job the tool lifts 20.32 mm above the material and goes through the whole process at this height. The 20.32 is reflected in a spot at the bottom of the toolpath window and is greyed out. Where on earth is V Carve getting this measurment from???

Under Material Setup, you can set the gap above material.

It shouldn't be running the whole job at that height though.

Have you cut with this machine before or is the first time?

For all the world this sounds like a case of job Z Zero is set to material surface and the machine thinking Z Zero is at the machine bed (or vice-versa).

Presuming that 20.32 is a metric mm value the inch value is 0.8 which is the Vectric default value for the Z gap above material that Gary pointed out.

Another possibility if the z-axis is not moving at all is that when the machine starts & the z-axis lifts it is topping out & tripping the z-axis driver
