After upgrading my Duet2 Wifi firmware to 3.2, I keep getting T0
Error: New tool too close to Z axis limit. Aborting tool change

I am using a delta

nothing jumps out at me as being incorrect with that config to cause the error you're seeing.
I take it you have changed the stepper motors to 0.9 degree ones? I hope you have some sort of cooling on the board for the current settings you have.

@ken340 said in New tool too close to Z axis limit. Aborting tool change:

M106 P0 S0 I0 F500 H-1 L0.5 ; set fan 0 value. Thermostatic control is turned off

F and I aren't valid here.

@ken340 said in New tool too close to Z axis limit. Aborting tool change:

G29 S1 ; Load the heightmap

There no point loading the height map here as it gets unloaded when G28 is ran.

Can you check the output of M98 P"config.g" and provide the start section of a gcode file? Do you also use start.g?

dvmourik

Look at your homedelta.g file

There are some lines that will put the head down a bit after homing. Still using H1 there will make it fail. Use the H2 to move the motors down a bit.

@jay_s_uk I actually bought the same 0.9 stepper as in your guide.

how should I configure M106?

I somehow overcome this by manually home and set T0 temp to 50 then turn off.

This would be typical for your fan settings

M106 P0 S0 H-1                                 ; set fan 0 value. Thermostatic control is turned off
M106 P1 S1 H1 T45                            ; set fan 1 value. Thermostatic control is turned on
