Hi,
I installed BLTouch to my 3D printer and everything went well and works fine. At one point I homed all the axes from the menu of the printer and the Z axis pushed straight into my bed and the BLTouch sensor did not trigger.
I investigated further and found the following: When there is cold filament unter the nozzle it prevents the nozzle to get close enough to the bed to trigger the BLTouch sensor. Therefore, it did not stop to go down which was not really good for the printer. Also with BLTouch the "normal" end stop is beind disabled which is on purpose to prevent that this one triggers before the BLTouch probe.
So here is my question: Is there an option to allow Z axis homing only when the nozzle has a minimum temperature? I could not find anything about this.
Does anyone know something how I can prevent this?
Thank you very much, Sebastian
