@lukas-aurarum try adjusting the H value in you M558 command that sets up the probe. I think default is 5mm. The z axis will travel an equal distance in the negative direction as the H value. So it will move 10mm before it gives up with the default of 5mm.

can you post your full config as it currently is please?

We considered various options, but the chips to read PT100 and thermocouple sensors are quite expensive, and we want to keep the price of the tool board as low as we reasonably can. PT1000 sensors are now readily available.

My guess it that it's the cable. If you connect a PC running YAT or Pronterface etc. to the Duet via USB and send M111 S1 P3, then every command received by the Duet will be echoed to USB. If the Duet is receiving data from the 5i then you should see "aux: M408" lines regularly.

Use M305 to set up a virtual heater that uses that thermistor (e.g. heater 102), then use M106 to control the fan thermostatically from that heater number.

Solved.

Was due to Maximum speed and acceleration of extruder not set high enough.

You could do it the other way round. Home Z using bltouch, then use a G1 S3 Z move with the type of Z endstop set to stall detection. That will adjust the tool Z offset.

Stall detection is at best accurate to +/- 1 full step of the motor.
