DEV2: G30 / G32 z-probe height
Hi,
I needed to replace my servo of my probe for measuring the bed height.
Therefore I started to use G30 to calibrate my probe. I observed things:
1. Using the graphic display and the control I was not able to set values above 10mm (but I need around 13mm).
2. When changing the value in the eeprom using reptier server, it has no effect.
When using G32 S2 the changes in the EEPROM have the expected effect.
Do I have to use G30 in a different way? Or is there a mistake?

is causing the 10mm limit. Have increased it to 20mm for next update also 13mm is quite high.
2. When I change it in eeprom and reset it is still there and also shown in menu (except if value is out of range of course then it might get clipped). But it does nothing until next command using it.
What code exactly do you run with G30 to calibrate? There are many uses and variation on that command.
The high value of 13 mm allows me to press reset before the nozzle is broken, if there is a problem with the z-probe. And it is simply the end of the standard length of the servo.
Is there a comparable list for Repetier only?
The problem with G30 is that it depends if you already correct bed rotation or not. So it is fine to run G32 S2 and then do a G30 test as you did - if the bed planar. If bed rotation correction is off z is not adjusted so real Z depends on where you run your test.
