I own a K2-2514 cnc routing machine.
Wherever I set the z=0 point along the z-axis, all movement above 0 are indicated as negative in mach2. And - of course - all movement below 0 are indicated as positive.
This is not correct.
The result has been that for all profiling jobs I have attempted, I am a newbie, the machine has attempted to start cutting from the deepest point in the stock.
Is there a way I can adjust this?
If I have to live with this, would reversing the polarity of all z values in my g-codes solve the problem?
