BL touch trig height in “web UI console” vs “web UI top left”
Johncoffee last edited by Johncoffee
I'm wondering why my trigger height reading from the web UI console window is sometimes different from the Z height at the web UI head position reading (top left in DW screen)
What reading is now correct?
I've repeated the shown example twice - both time the same readings.

@johncoffee I don't use a BLT touch but my best guess would be that the difference is the Z offset.
The "stopped" height is the machine Z coordinate. The displayed height is the user Z coordinate. The following all cause the two to be different:
- A G10 Z offset for the current tool
- Baby stepping (send M290 to see if any is in effect)
- Bed compensation (send G29 S2 to cancel it)
- Workplace coordinate offsets
