RE: Sensorless homing not working with Duet 3 mini
@gloomyandy I owe you for that one, many thanks indeed. It is homing on this, will revert at end of homing to spreadcycle. Thanks again

RE: Rare negative readings from filament sensor causing pause
@jay_s_uk Hi I use events for some of the errors, to filter out other issues. I don't see where the actual measured variable is recorded or how it is named.
something like if measure value is < 0 then..... Many thanks -
Rare negative readings from filament sensor causing pause
I have had a couple of circumstances when I have had a negative reading from the filament sensor. I would like to ignore these errors and prevent negative readings causing a pause. Does anyone know the best way to achieve this? Many thanks Jeremy

RE: Sensorless homing not working with Duet 3 mini
Anyone know why stallguard doesn't initiate with duet 3 mini. Changing the sensitivity doesn't work, it is just not responsive. It clatters no matter what. I can get it working on a Duet 2 board without any hiccup at all with a super light touch as well. It doesnt appear to be firmware related as I rolled back to 4.6..

Sensorless homing not working with Duet 3 mini
I am not able to get sensorless homing working with a duet 3 mini running firmware 3.5 rc2. I have looked and cannot see where it is going wrong and have tried numerous settings to no avail. Not sure if I should go back to an older version of the firmware. Hopefully I am missing something really stupid. My main config is below followed by my homex file. Many thanks

Magnet too strong error message with Duet V3 filament sensor
Hi I would like to know what is the distance between the magnet and the sensor on the V4 filament sensor should be. The housing designed by Lo-fi gives an error of magnet too strong. The standard housing is working fine but there is a little more filament resistance. If I know the optimum distance I may modify the Lo-fi housing to deal with the change in magnet of the new version (V4) Anyway if someone knows the dimension it would make things very simple. Many thanks Jeremy

RE: Handling error codes to switch off power using M81
Hi Andre
Thanks for your help, makes sense.

Handling error codes to switch off power using M81
I am trying to understand if there are any settings to get the duet to switch off the 24V power supply using the M81 command. As far as I can see the heaters are turned off if it detects an issue, but it does not turn off the power supply. I can switch the power on and off no issues and this is handy at the end of printing. However I am not sure about how error messages can be arranged to power down the 24 volt power supply.
Many thanks
Jeremy
