No negative z-numbers on wireless MPG
I am using the wireless handwheel as supplied from Planet-CNC. Works well but have not used it extensively.
Today I was running a tool path that starts with a positive z-value and ends up slightly negative. But noticed when the tool ends up below zero, the display stays positive.
In that case, the screen display jumps from +2.10mm to -0.99mm (which is correct and what the bit is doing) and the MPG display jumps from +2.1mm to +0.99mm.
