First thing you should do, if you haven't already, is upload the latest firmware to your printer from here http://www.geeetech.com/forum/download/file.php?id=3543

If that doesn't work, try the following steps, one at a time:

1. Make sure that the Z axis drives are at the same height. Measure ...

Sorted, it was a lazy copy/paste into configuration.h on my part
Without checking (duh) I just copied in a number of lines including this #define Z_PROBE_OFFSET_FROM_EXTRUDER -1.4
Not even sure why I would have changed that, I'll blame the kids...
Rookie error, sorry for wasting your time

Is there no change when setting different Z offset?


Setting different offsets makes no difference. The offset reports as having changed to the new value but I still cannot drive down below -1.39

I've now upgraded the firmware to 1.1.8 which also makes no difference.


Here's a thought, I ...

I am aware where the home positions are supposed to be, but the hotbed (Y-axis) moves to the opposite end when sent to the home position. The end-stop microswitches have nothing to do with the direction of travel, do they?


FYI
If the printer thinks that the endstop microswitch has been ...

My printer has behaved itself until this afternoon when it started to have printing problems caused by the nozzle being too high.
The printer uses a 3DTouch probe and I attempted to do a calibration using https://www.geeetech.com/wiki/index.php/3DTouch_Auto_Leveling_Sensor#Calibration which has ...

The X and Y Home position equates to the location of the X&Y endstop microswitches.
The wires on the microswitches should be connected to the outer lugs.
The connectors from the microswitches should go into the 1st (X) and 3rd (Y) sockets from the edge of the board. The sockets are labelled on the ...

The pin on my 3DTouch was randomly dropping down causing massive print failures. The LED remained lit so it was not being driven down.

To correct this I followed a suggestion to remagnetise the pin by unscrewing the top grub screw and removing the pin and leaving it stuck to a Neodymium magnet ...

This is not a question, just a FYI.
I don't know if the extruder head design has changed since the wiki was written but...
